    The present invention relates to a dynamic mixer.
    From WO 2007/041878 A1 a dynamic mixer is known for mixing components of different volumes, in particular for the production of molding compounds for dental molds. An antechamber is arranged in the internal space of the mixer housing, within which the mixing rotor has a distribution element for the distribution of the components around its axis of rotation in order to obtain a correct mixing ratio between the components. and avoid air inclusions. Subsequently, for their complete mixing, the premixed components arrive through at least one passage opening, in a main chamber.
    In particular, in high mixing ratios of viscous or pasty components, it is particularly difficult to keep constant the correct mixing ratios and to obtain a satisfactory mixing. Generally, mixing is carried out by gravitational forces, whereby the components are pressed through the mixer. The mixer has a housing and a rotor element, which are hingedly arranged in the housing, in which the housing has a respective inlet opening for at least two components and at least one outlet opening. Between the rotor elements and the housing, an intermediate space is provided in a ring shape, in which a mixing element is installed in the rotor element. The rotor element consists of the body element and the mixing element. This mixing element is formed as a vane element, which protrudes from the body element into the intermediate space. Preferably, there is a multiplicity of these elements in the form of reeds. In addition, static mixing elements can also be projected from the internal wall of the housing to the interior of the intermediate space, which, however, from the technical point of view of production, can only be executed with great difficulty. The components are repeatedly moved by means of kneading through one or more elements in the form of vanes as well as, if necessary, static mixing elements. The objective is to produce the largest possible phase interface between the components, as, by splitting and rearranging the component flows, a profusion of layers as thin as possible is produced to obtain an efficient mixing. Until now, this mixing effect had been produced by the mixing elements, whereby the flows, as a result of the transverse movement of the rotor in relation to the direction of the main flow, are subdivided and the largest part of the filling material is pushed away against the main flow direction, so that the back flow filling material, after the mixing element, follows as a downward flow and thus produces displacement and layer formation of the filling material components. The most difficult mixing tasks lead to longer mixing actions and, therefore, a high energy consumption for the activation of the mixer and a higher resistance for the compression of the components through the mixer.
    For this reason, until now, it has been necessary to face the following disadvantageous consequences: a longer mixer, a high energy consumption, as well as a high pressure loss. Therefore, larger and heavier drive sets and batteries should be provided for the discharge equipment, which limits handling for the application of the mixture, increases energy consumption and, in the case of battery activation, reduces the periods of use of unloading equipment.
    Since, in an interruption of the discharge, the components in the mixer react with each other and solidify, the mixer must be replaced, together with the components contained therein, and discarded after use.
    W02005 / 082549 A2 reveals a dynamic mixer that features mixing elements that are arranged along a rotation cube and project into the mixing space. The mixing elements have a triangular, rectangular or trapezoidal cross-section. The apex of the triangle or the two shorter sides of the trapezoid receive the flow. As already foreseen in WO 2007/041878 A1, in particular, in the mixing elements that have a triangular, rectangular or trapezoidal cross-section, most of the filling material is pushed away, so that the filling material that flows after the mixing element follows as a downward flow and thus produces a displacement and layer formation of the components in the filling material, which leads to the same disadvantages that are already mentioned in WO 2007/041878 A1.
    DE 102 2 100 A1 discloses a stirrer with a rotary agitator about a central axis. The agitator is configured as a helical blade mixer. The direction of rotation of the stirring device is such that the stirrer, in the axial direction of the mixture, promotes the outlet, so that an axial pumping effect is created, which results in an increasing stirring speed , the mixing chamber can be kept reduced or constant. That is, with this stirring mixer an improved transport effect as well as a lower pressure loss can be obtained, however, this results in a reduction of the mixing effect in relation to an isolated helical blade element. For this reason, the mixer length increases, so the solution is contrary to the goal of creating a mixer configuration of the shortest possible length.
    WO 98/43727 A1 discloses a dynamic mixer with mixing elements, which in cross section have a rhomboid (or cylindrical) shape. A mixing channel is configured between the rotation hub and the mixer housing, the diameter of which decreases in the direction of the outlet side of the mixer. Thereby, an acceleration of the axial movement of the filling material is obtained, that is, the flow of the filling material flows more quickly through the mixer, however, the mixing efficiency only increases with additional measures, that is, in the measure in which the mixing blades are arranged in the different axial areas of the mixer shaft in different directions, which in turn results in an increase in pressure loss. A similar solution is also shown in Fig. 6, 7 of DE 199 47 331 A1, with a considerable difference, in that the mixer housing is rotatable in relation to the fixed mixer hub. So that, with this solution, it is possible to obtain an adequate mixture with materials of high viscosity, the mixing vanes are arranged in a greater number of levels, which results in a greater axial length configuration of the mixer.
    DE 101 12 904 A1 discloses a dynamic mixer with a delay chamber, so that the components enter the mixing chamber with a greater volume proportion with a delay compared to the components with a lower volume proportion. This ensures that both components are subjected to mixing from the beginning, so that the total length of the mixer can be reduced. However, it is necessary to pay attention that no dead zones appear. The vane elements are not intended to produce any transport action. For this reason, in relation to WO 2007/041878 A1, in the area of the mixing chamber containing the vane elements, no improvement in the quality of the mixture can be achieved.
    DE 10 2007 059 078 A1 discloses a dynamic mixer that features trapezoidal vane elements and perforated plates as intermediate elements. The arrangement aims to delay the rotation of the media in the mixer, which can be disadvantageous for a mixture of fast-setting components. With this arrangement, a transport effect developed as usual would not be the desired one, because it would be the exact opposite of the desired one.
    US 2009/0034357 A1 discloses a dynamic mixer with a deflection element, which is arranged at the outlet end of the rotation hub. The mixing elements of US 2009/0034357 A1 correspond substantially to those of DE 101 12 904 A1. Therefore, this document reveals that the mixing effect of the reed elements can be considered insufficient and, for this reason, an additional element, ie a deflection element, is provided to increase the quality of the mixture. Alternatively, for this purpose, a static mixer may be provided at the outlet end of the mixer, as disclosed in US 2009/0207685 A1. The vane elements with trapezoidal cross section have already been presented in WO 2005/082549 A2.
    In accordance with EP 1 099 470 A1, installed in the mixer housing, fixed removal elements are provided between the vane elements arranged in a rotating manner on the rotor hub. These removal elements have no transport effect, they only have the objective of improving the mixture.
    DE 199 47 331 shows a dynamic mixer with a rotor hub attachment at the mixer outlet. Therefore, because the rotor hub is arranged at the outlet of the mixer, it has a channel for the discharge of the mixture. The mixing vanes, as usual, do not have any transport function, as in column 3, line 48, it is observed that the pistons press the material outwards. These plungers should belong to a discharge device by means of which the contents of the cartridge are expelled out by compression.
    Therefore, the task of the invention is to find a mixer that has a reduced length and that performs difficult mixing tasks with the lowest possible energy consumption for the rotor as well as it achieves it with less pressure loss through the mixer. The mixers are produced in large quantities. With small mixers it is possible to save on material for the mixer, on components as well as to reduce costs for the disposal of the mixers used.
    The task of the invention is achieved by means of a dynamic mixer for a multiplicity of fluid components, which comprises a housing and a rotor element, which is rotatably arranged in the housing. The housing has an inlet opening for at least each of the components and at least an outlet opening, in which an intermediate space in the ring shape is provided between the rotor element and the housing, in which a mixing element connected to a rotor element. The mixing element has a vane element, which is formed as a conducting element for the transport of the elements from the inlet opening to the outlet opening. The vane element is a conductive element that has a conductive surface which, in relation to the outlet opening, has a concave curvature and on the upward flow side is more distanced from the outlet opening than on the downward flow side.
    According to a configuration example, the vane element does not cover more than 50% of a plane defined by the intermediate space that contains the vane element and is oriented perpendicular to the axis of the dynamic mixer. A multiplicity of vane elements can be arranged on at least two parallel planes, essentially perpendicular to the axis of the dynamic mixer.
    According to a configuration example, a first vane element and a second vane element are arranged in a main chamber in downward flow from the first vane element, in which the shortest distance between the first vane element 20 to the second vane element is at least one third of the distance between the rotor element and the main chamber limitation defined by the housing. In this case, the shortest distance is defined as the distance between the limitation of the main chamber in the housing in the direction of the longitudinal axis of the dynamic mixer.
    According to an example of configuration, the vane element has a cross-sectional surface, essentially in trapezoidal shape. In particular, the vane elements may have an upstream retaining surface, whereby the plane of the retaining surface is arranged parallel to the axis of the rotor element or at an angle so that the retaining surface faces towards the exit opening.
    The vane elements of the dynamic mixer can, in particular, be arranged in pairs with each other. In this case, the arrangement in pairs means that, respectively, two vane elements are arranged on a plane, which is placed perpendicular to the rotor axis. In particular, the vane elements may be arranged in pairs arranged opposite each other. This means the arrangement of a first vane element, displaced 180 ° with respect to a second vane element of a pair of vane elements. For adjacent pairs of vane elements, the vane element of a first pair of vane elements is considered to be displaced relative to a second pair of vane elements in the direction of exit or in the direction opposite to the exit along the axis of the rotor as well as arranged rotated by an angle. In particular, the geometric arrangement of two adjacent pairs of vane elements occurs so that the first pair of vane elements can be converted by an axial displacement along the rotor axis and a subsequent 90 ° rotation around the axis of the rotor on the second pair of vane elements.
    Adjacent pairs of vane elements can have a different geometric configuration. In particular, adjacent pairs of vane elements can have a geometric configuration which, alternately, can be carrier or non-carrier. In this case, under "carrier" it should be understood that the inclination or curvature of at least one conductive surface of the vane element favors a subsequent flow of overlying filling material and contributes to the mixing.
    According to an example of configuration, the vane element has the upward flow retaining surface, a downward flow terminal surface, a cover surface that extends on the outer circumference between the upward flow side retaining surface and the end surface on the downward flow side, a base surface that faces the inlet openings, as well as a cover surface that faces the outlet opening.
    In particular, the cover surface may have a base edge, which has a continuous curvature, facing the inlet openings. The radius of curvature increases, according to a configuration example, from the base edge of the upstream flow retention surface towards the downstream flow end terminal surface. Alternatively or in combination hereby, the base edge may have an S-shaped course. In particular, the radius of curvature of the base edge from the upstream side to the downstream side may be constant in sections. Alternatively, or to complete, the covering surface may have a covering edge facing the outlet opening, which has a continuous curvature. The course of curvature of the cover edge may differ from the course of curvature of the base edge.
    The curvature may have a minimum radius of curvature of 1 mm and a maximum radius of curvature of 100 mm, preferably a maximum radius of curvature of up to 50 mm.
    Preferably, the mixer comprises a maximum of 5 rows of vane elements, preferably a maximum of 4 rows of vane elements, most preferably a maximum of 3 rows of vane elements which are arranged on the rotor element . Hereby, in comparison with the level of the technique, the length of the configuration can be greatly reduced. As a result, there is a reduction not only in costs, but also the filling volume is reduced, so that after using the mixer, the remaining filling material decreases. As a result, the mixer according to one of the configuration examples can also be reduced in proportion to the filler waste.
    According to an example of configuration, the housing comprises a first antechamber and a main chamber, in which the entrance openings lead to the first antechamber, in which the components are incorporated for the first time. In particular, between the first antechamber and the main chamber, a second antechamber may be provided. Between the first anteroom and the second anteroom, at least one opening between the rotor element and the housing for the passage of the components may be provided. According to a configuration example, a mixing element can be arranged in at least a first and a second antechamber. The components can, in the second of the antechamber, be guided in the radial direction of the rotor element, as well as be guided by the mixing elements installed in the rotor element or laterally in the housing, before being driven by a deflection in axial direction to the inside of the main chamber.
    According to an example of configuration, the first part of the housing has, in at least one of the inlet openings, a device for piercing a container containing the components.
    It turned out that, even contrary to the general opinion at the level of the prior art, good results in terms of displacement and layer formation can also be obtained if, at least, the filling material, at least, by some elements mixture, it is not pressed against the mixing elements in the vicinity of these elements, but in the direction of the main flow towards the outlet opening and the filling material which is thereafter in a downward flow is removed from the main flow which flows more slowly. The main flow is between the inner wall of the housing and the rotor element. The geometry of the mixing elements influences the flow, essentially only in place, however, it influences the effect of the mixing, the resistance to rotation of the rotor element and the pressure drop of the components through the mixer. At least a part of these mixing elements has, respectively, a transport effect, which reduces the resistance to the compression passage of the components and the energy consumption for driving the rotor. In addition, it has also been found that, for a required mixing effect, the residence time of the components in the dynamic mixer can be reduced and, thus, the entire dynamic mixer can be built more compact and with less content.
    The mixing ratio of the first and second components can be from 1: 1, but it can also be from 1:10 to 1:50 or it can even be above that.
    The use of the dynamic mixer is preferably carried out in portable stand-alone manual discharge devices or in fixed devices for desktop computers.
    In the following, the invention is explained in detail based on drawings that show in:

    Fig. 1 shows a dynamic mixer for a multiplicity of fluid components. The dynamic mixer 1 has a housing 2 and a rotor element 3, which is pivotally arranged in the housing 2 around an axis of rotation 8. In the present form of configuration, the housing 2 is configured in two parts, it contains a first housing part 4 in which the supply of components is located and a second housing part 5, which acts for the production of a mixture from a plurality of fluid components. The first part of the housing is connected to the second part of the housing by means of a retaining connection, a plug-in connection or a welding connection, once the rotor element 3 is incorporated into the second part of the housing 5. The first part of the housing 4 has an inlet opening 12, 13 for at least each of the components. The inlet openings 12, 13 can have a different diameter depending on the desired mixing ratio of the components. The entrance openings flow into the corresponding entrance channels 10, 11, which are arranged in the first part of the housing 4. The entrance channels 10, 11 flow into the first antechamber 21 5 which is provided with exit openings produced, essentially, by a external annular slit, which opens into an internal space 15 of the second part of the housing 5.
    The second part of the housing 5 has at least one outlet opening 20. Through the second outlet opening 20, the mixture 10 of the components leaves the dynamic mixer. The outlet opening 20 can be specially configured according to the intended use. In the present case, a V-shaped notch is provided. With the help of this V-shaped notch, the filling material results in the shape of a triangular granule. The internal space 15 of the second part of the housing 5 is intended for the incorporation of a rotor element 3.
    The internal space 15 has a second antechamber 17 and a main chamber 22. In the second antechamber 17 there are the components, which, in the first antechamber 21, were brought into contact with each other for the first time and were premixed. The components are conducted from the second anteroom 17 to the main chamber 22. In the second anteroom 17 another premix can occur. For this, a multiplicity of mixing elements 18 is arranged in the antechamber. These mixing elements are configured as pin elements, which project into the antechamber. Alternatively, the 25-pin elements can be arranged on a rotating surface 19 of the rotor element 3 or, as shown in Fig. 1, the inner wall of the housing, which delimits the antechamber, protrudes into the antechamber 17. By means of the rotating surface 19 and the pin elements 18, shear forces are applied on the components. In this way, the components are mixed relatively thin.
    Between the rotor element 3 and the inner wall 6 of the housing, an intermediate space in the form of a ring is provided, which forms the main chamber 22, in which a mixing element 7 connected with the rotor element 3 is arranged.
    The mixing element 7 comprises, in the main chamber 22, a multiplicity of vane elements 23. The vane elements 23 project as projections into the main chamber 22. In this main chamber 22 the final mixing of the components occurs, as in which the components are seized and moved by the vane elements. At least part of the vane elements are configured as conductive elements for transporting the components through the internal space 15 in the direction of the outlet opening 20.
    Fig. 2 shows a section through a dynamic mixer, according to a second configuration example of the invention, for mixing a plurality of fluid components. The dynamic mixer 100 has a housing 102 and a rotor element 103, which is rotatable about a rotor axis 108. In the present configuration, housing 102 is mounted in two parts, it contains a first part housing 104, which contains the component feeds and a second housing part 105, which serves to produce a mixture from a plurality of fluid components. The first housing part is connected to the second housing part by means of a retaining connection, a plug-in connection or a welding connection, as soon as the rotor element 103 is incorporated into the second housing part 105. The first part of the housing 104 has an inlet opening 112, 113 for at least each of the components. Inlet openings 112, 113 can have a different diameter, which depends on the desired mixing ratio of the components. The entrance openings flow into the corresponding entrance channels 110, 111, which are arranged in the first part of the housing 104. The entrance channels 110, 111 flow into the first antechamber 121 which is provided with exit openings 130, 131, which open in an internal space 15 of the second part of the housing 105.
    The second part of the housing 105 has at least one outlet opening 120. Through the second outlet opening 120, mixing of the components leaves the dynamic mixer. The internal space 115 of the second part of the housing 105 is intended for incorporating a rotor element 103.
    The internal space 115 comprises a second anteroom 117 and a main chamber 122. The second anteroom 117 contains the components, which, in the first anteroom 121, are brought into contact with each other for the first time and are premixed. The components are conducted from the second anteroom 117 to the main chamber 122. In the second anteroom 117, another premix can take place. For this purpose, a mixing element 118 is arranged in the second antechamber 117. The mixing element 118 is formed as a vane element, which is connected with the rotor element 103. In addition, other mixing elements 118 can be arranged. on a rotating surface 119 of the rotor element 103, which is not shown in Fig. 2. Shear forces on the components are applied by means of the rotating surface 119 and the pin elements 118. In this way, the components are still mixed together.
    Between the rotor element 103 and the inner wall of the housing, an intermediate space in ring shape is provided, in which a mixing element 107 is connected connected with the rotor element 103.
    The mixing element 107 covers, in the main chamber 122, a multiplicity of vane elements 123. The vane elements 123 project as projections in the internal space 115, which forms the main chamber 122. In this main chamber the mixing of the components, as the components are apprehended and displaced by the vane elements. At least part of the vane elements are configured as conductive elements for transporting the components through the internal space 115 in the direction of the outlet opening 120. In particular, the vane elements can be formed according to each of the variants presented in figures 5 to 7.
    Furthermore, it is also not necessary that the vane elements subsequently disposed in relation to the rotor axis 108, have the same distance from each other. For example, if the distance of the vane element 123, which is arranged closer to the outlet opening 120, is less in relation to the vane element 126 than the distance of the vane element 126 from the vane element. 128.
    Fig. 3 shows a view of the rotor element for use in a dynamic mixer according to one of the preceding configuration examples. The rotor element corresponds to that rotor element 102 shown in Fig. 2, therefore the same reference numbers are used for identical parts as used in Fig. 2. However, this reference is not intended to limit in the sense that the rotor element can only be used in connection with the configuration example according to Fig. 2. Instead, the rotor element can also be used with a small adaptation of the housing geometry in a housing according to with one of the other forms of configuration. The rotor element 103 has a rotor shaft 108, along which a rotor element hub 135 is arranged. The rotor element hub 135 carries a crown element 136, which contains outlet openings 130, 131. Through these outlet openings 130, 131 the components introduced in the first anteroom 121 of the input channels 110. 111 (see Fig. 2) exit to the second anteroom 117. The crown element 136 constitutes a limit of the first anteroom 121. In the crown element 136, conductive elements are projected, which project in the first antechamber 121. The external conductive elements arranged in the crown element 136 shear the components of the outlet openings of the inlet channels 110, 111 and guide them into the space of the first antechamber 121 and thus produce a first contact of the components and, in addition, ensure constant levels of mixing rate. In addition, the conducting elements that are internally arranged ensure a first premix. A second limitation of the second antechamber 117 is the rotating surface 119 which is arranged in a downward flow of the crown element 136 over the rotor element hub 135. The antechamber 117 is bounded on the circumferential side of the second housing part 105 (see Fig. . two).
    The components are pre-mixed using a mixing element 118, which is arranged in the antechamber on the rotor element hub 135 and possibly on the rotating surface 119 or on the downward flow side of the crown 136. The mixing element can be configured as a vane element according to one of the configuration examples shown in figures 5 to 7.
    To enter main chamber 122 (see Fig. 2), the components flow around the rotation surface 119. Between the rotation surface 119 and the inner wall of the second part of the housing remains a narrow ring-shaped slot or segment slit in the form of a-15 level, through which the components pass through entrance channels formed laterally in the housing and reach the main chamber. In addition, vane elements 123, 126, 128 are disposed in the main chamber in a downward flow of the rotation surface 119, which are configured as conducting elements. In addition, vane elements 137 may be provided, which are configured in a diamond shape, as described, for example, in WO 98/43727. In addition, a curvature-shaped vane element 138 is present, which is immediately adjacent to the rotating surface and subjects the filling material of the inlet openings to the shear and leads to the main chamber 25. Other similar vane elements may also be arranged in a downward flow, which cause a removal of the filling material from the main chamber wall 22, 122. Preferably, at the same height along the rotor axis 108, in opposition to each other , similar vane elements are arranged.
    Fig. 4 shows a view of a rotor end of a rotor element 3, 103 according to a first variant according to the invention, which shows reed elements 23 that are configured as conductive elements. The conductive element according to this configuration example has a first conductive surface 24, which is oriented towards the first antechamber 17 and a second conductive surface 25, which is oriented towards the outlet opening 20. The second conductive surface 25 extends, essentially, parallel to a normal level on the axis of the rotor 8, while the first conductive surface is configured so that the transverse surface of the conductive element increases in the direction of rotation. Advantageously, the affluent surface 26 of the vane element in relation to the plane of the axis of rotation is deviated so that it indicates in the direction of the outlet opening 20.
    Fig. 5 shows a view of a rotor end of a rotor element 3, 103 according to a second variant according to the invention, which comprises conducting elements of different configuration. The vane element 33 has a first conductive surface 15, which is oriented towards the second antechamber 17, 117 and a second conductive surface 35, which is oriented towards the outlet opening 20, 120. The second conductive surface 35 has a convex curvature. The usual distance between the first conductive surface and the second conductive surface increases in the direction of rotation.
    In particular, the rear end of the first and second conductive surface may be formed as an edge 36. On the side opposite edge 36 is an affluent surface, preferably inclined with respect to the rotor axis, on which the material of filling that flows over the conductive element is divided and driven towards the outlet opening 20, 120.
    The inclination and curvature of the conductive surface 35 favors a subsequent flow of the superimposed filling material and thus contributes to the mixing.
    The vane element 43 has a first conductive surface 44, which is oriented towards the second antechamber 17, 30 117 and a second conductive surface 45, which is oriented towards the outlet opening 20, 120. The second surface conductor 45 has a curvature. The usual distance between the first conductive surface 44 and the second conductive surface 45 can increase, decrease or decrease it in the direction of rotation. The front ends of the first and the second conductive surface 44, 45 are disposed apart from each other. By this means a retaining surface 46 is created, which submits the filling material composed of components, as an interference element, to a deflection and divides it. The filler portion, which is guided through the second conductive surface 45, by means of its curvature, is transported towards the outlet opening 20, 120. The first conductive surface 44 can also have a curvature. In particular, the curvatures of the first and second conductive surfaces 44, 45 can be similarly.
    In particular, according to Fig. 6, a vane element 53 can be provided, which has an indication towards the outlet cover 20, 120. That is, the first conductive surface 54 has a convex curvature. The second conductive surface 55 has a concave surface in relation to the outlet opening. The geometric configuration of the vane elements can be similar to the vane element 43. In particular, the rotor element can consist of only one vane element 53.
    Preferably, in each of the configuration examples, a plurality of vane elements are arranged on the circumference of the rotor element. In particular, a plurality of subsequent vane elements can also be arranged in the direction of the axis of the rotor element. According to the manufacturing technique, it is advantageous when the diametrically opposed vane elements are of the same type. Preferably, the subsequently arranged vane elements are not all of the same type.
