    SUMMARY OF THE INVENTION It has been found that the main problems with the rotor of the existing pulp are:
    Processing difficulties on the shape of the spiral blade of the pump blades and connection strength between the pump blades and the hub. For this reason, the rotor of the existing pulp is only produced by pouring or casting or one-piece casting.
    It has been found that by using the pulper rotor and pulper of the present invention, the pump blades and blades of the rotor can be prefabricated separately from the plate or plates and then connected to the hub to solve the above problems , In particular, the sheet material for the corresponding part can be cut out of the plates based on its shape and size, and then the blades of the rotor and the like are formed by bending, stamping or rolling. Thereafter, the pump blades and the blades are each attached to the periphery of the hub by means of a fixed connection type of welding, fusion welding, riveting or the like, whereby the problem of the difficulty in molding can be solved. Furthermore, at least a part of the end side and the bottom of the pump blades are attached to the circumference of the hub by the fixed connection type of welding, fusion welding and the like. In addition, the bottom of each of the pump blades is also attached to the bottom of each of the blades. As a result, the pump blades, the hub and the blades form a stable structure in order to meet the structural strength requirements.
    Having introduced the basic principle of the present invention, various non-limiting embodiments of the present invention will now be described.
    EXEMPLARY DEVICES Figure 1 is a structural schematic side view of a pulper rotor according to an exemplary embodiment; 2 is a structural schematic top view of a pulper rotor according to an exemplary embodiment; and FIG. 3 is a schematic perspective view of a pulper rotor according to an exemplary embodiment.
    As shown in the drawings, an embodiment of the present invention has a main body structure of a pulper rotor 1, which essentially has a hub 2, a plurality of blades 3 and a plurality of pump blades 4. The plurality of blades 3 and the plurality of pump blades 4 surround the hub 2 and the roots of the plurality of blades 3 and the plurality of pump blades 4 are attached to the hub 2. The blades 3 and the pump blades 4 are made separately from one another from a plate and then firmly connected to the hub 2. A lower surface of each of the pump blades 4 is connected to the corresponding blade and each of the pump blades 4 is arranged on the corresponding blade 3.
    In a special embodiment, the hub 2 in its entirety has the shape of an inverted cone, which essentially has a main body of the cone 21 and a connecting base body 22, which extends from an upper section. The cone 21 has an inclined outer side surface. The blades 3 and the pump blades 4 are essentially connected to the outer side surface. An outer end of the upper portion of the connection base body 22 may form a flange or a similar connection structure for connection to an external power coupling element. The hub 2 is formed by stamping a plate or is formed by casting or the hub 2, on the other hand, can be formed from a high strength starting material by drilling and milling in an embodiment with high strength requirements.
    In the specific embodiment shown in Figures 2 and 3, the plurality of blades are designed as a flat, sheet-like structure. Each of the blades 3 is on one
    4.11

    Patent Office
    Side inclined with respect to a radial line of the hub 2. In the specific embodiment, the outer end of the blades 3 is inclined opposite to the direction of rotation of the rotor 1. Each of the blades 3 has a curved front edge 6 and a rectilinear rear edge 7. In a specific embodiment, the front edges 6 are designed as a smooth curve and the shape of an outer edge of each of the pump blades 4 can be aligned with the shape of the front edges 6.
    In the specific embodiment shown in Figures 2 and 3, the plurality of pump vanes 4 surrounding the hub 2 can be divided into pump vanes 4 of full length and pump vanes 4 'of incomplete length. The pump blades 4 with full length and the pump blades 4 'with incomplete length are arranged such that they are offset from one another or that they alternate with one another. As shown in the figures, both sides of a pump vane 4 with full length are each provided with a pump vane 4 'with incomplete length, while both sides of pump vanes 4' with incomplete length are also each provided with a pump vane 4 with full length, so that the pump vanes 4 with full length and the pump vanes 4 'with incomplete length are offset from one another in the same size ratio or alternately.
    One end of the pump vane 4 with full length is connected to the outer end of the blades 3 below and the other end of the pump vane 4 with full length extends up to and is connected to a side surface of the connecting base body 22. At the same time, part of one lower surface of the pump vane 4 with full length is connected to an outer side surface of the cone 21 and the other part of the lower surface of the pump vane 4 with full length is connected to the main body and is arranged on an upper surface of the blade 3. Most of the lower side surface of the incomplete length pump vane 4 'is connected to the blade 3 and an inner end surface of the incomplete length pump vane 4' is connected to an underside of the outer side surface of the cone 21. The structure of the impeller 4 of the rotor in the present embodiment has only the impeller 4 with full length on the inner side adjacent to the axis of rotation and has both impeller 4 with full length and impeller 4 'with incomplete length on the outside away from the axis of rotation. The inner ends of these two types of vanes are not aligned, so that when the rotor is rotated at a high speed, the inner side of the rotor adjacent to the axis of rotation still has a good shredding effect. The decentering or offset of the inner ends of these two types of wings is not only able to reduce their respective weights, but can also improve the crushing effect.
    In the specific embodiment shown in Figs. 2 and 3, each of the pump vanes 4 is inclined from 5 to 20 degrees (the angle a shown in the drawings) from one side away from the blade 3 to the other side. In other words, an upper surface of the pump blades 4 shown in the drawings is inclined 5 to 20 degrees forwards or forwards, which refers to a direction pointing forward from the direction of rotation of the rotor. At the same time, a root of each of the pump blades 4 is inclined by 10 to 30 degrees (the angle shown in the drawings in the same direction in which the blades 3 are inclined, while a tip of the pump blade 4 is 20 to 50 degrees (that in FIG angles ß 2 ) shown in the drawings are inclined in the same direction in which the blade 3 is inclined, at least a part of each of the pump blades 4 is designed in a serrated or wavy shape 8 on a side facing away from the blades 3 and an upper side the serrated or corrugated shape 8 is inclined towards the root of each of the pump vanes 4. The side of the upper portion of the pump vanes 4 is designed as a serrated or corrugated shape and is inclined towards the root of the pump vanes 4. Fibers or paper that moving from the middle part of the rotor 1 to the outside, is shredded or frayed when the rotor 1 acts. The main body of each of the pump blades 4 is as one e Formed a spiral surface and specific shape parameters can vary from

    Patent office can be flexibly selected by experts, according to environmental conditions and work requirements that are not described here.
    With respect to the designations, the angle α refers to an angle at which the pump blades 4 are rotated forward or forward. Therefore, because an upper surface of the impeller 4 is slightly inclined in the direction of rotation of the rotor, it pushes the material to flow down (toward the flow plate), βτ refers to an angle of the impeller 4 from the hub 2 of the rotor 1 to a radius of the rotor 1 and β 2 refers to an angle between a closing end of the pump blade 4 and the radius of the rotor 1.
    In one embodiment of a special manufacturing method of the present invention, the materials of the hub 2, the blades 3 and the pump vane 4 can be made of a stainless steel plate, which is designed so that the sheet material for the corresponding part based on their size and Form is cut out of the plate and then the hub 2, the pump blades 4, the blades 3 of the rotor 1 and the like are each formed by bending, punching or rolling. Thereafter, the pump blades 4 and the blades 3 are each fixed on the periphery of the hub 2 by means of a fixed type of welding, fusion welding, riveting and the like, whereby the problem of the difficulty of manufacture can be solved. Furthermore, at least a part of the end side and the lower side of the pump blades 4 are fixed to the periphery of the hub 2 by the fixed manner of welding, fusion welding and the like. In addition, the lower side of the pump blades 4 is also attached to the lower side of the blades 3. The pump vanes 4, the hub 2 and the blades 3 therefore form a stable structure in order to achieve structural strength requirements.
    In a preferred embodiment, the hub 2, the blades 3 and the pump vanes 4 are made of stainless steel plates with different qualities to use the material based on the strength or strength conditions of the different components, which offers advantages of better suitability and cost savings can be achieved. In addition, the hub 2, blades 3 and pump vanes 4 are each welded together to ensure that the strength of the connection meets the design requirements.
    Another aspect of the embodiment of the present invention also provides a pulper that includes the above-mentioned powder rotor 1. The pulper has a main body with a tub shape. The powder rotor 1 is attached to the lower side or side surface within the main body with the tub shape. A drive spindle is connected to the hub 2 of the rotor 1 to rotate the rotor 1. During the rotation, the rotor 1 rotates at a high speed. Pulp bales are first broken into smaller pulp blocks by the pump blades 4 and then these pulp pieces begin to move from the rotor 1 to the side wall and then up and back down to the center of the rotor 1 from the middle section due to a strong one Circulation generated by the pump blades 4 on the rotor 1. During the circulation, the pump blades 4 not only generate a circulating pumping force, but also use the side to shred or shred the pulp bales.
    [0043] It should be understood that various examples described above can be used in different orientations (e.g. inclined, reversed, horizontal, vertical, etc.) and in different configurations without departing from the principles of the invention. The embodiments shown in the drawings are shown and described only as an example of effectively applying the principles of the present invention, and the present invention is not limited to any specific detail of these embodiments.
