    [001] The present invention relates to a separator according to the preamble of claim 1.
    [002] Centrifugal separators for realization and continuous operation have been known for a long time, as in a configuration as nozzle separators of document JP 62-1176- 49 A. A separator with lower drum parts and solid drum upper parts, screwed together, it is shown, still in US 2,286,354. In addition to nozzle separators, those with solid discharge openings are known, to which a cylindrical distributor is associated, with which the solid discharge openings can be closed and released. A separator without solid discharge in a formation as a separator is shown in US 2,017,734.
    [003] In centrifuges with a known construction method, particularly with regard to the processing of products under hygienic conditions, there is a need for new construction paths.
    [004] The solution to this problem is the task of the invention.
    [005] The invention solves this problem with the object of claim 1.
    [006] A separator is created to separate a fluent product in several stages or to clarify a product, with at least the following characteristics: a rotating drum, with a lower drum part and an upper drum part and a disposed medium in the clarification drum, one, several or all of the following elements consisting of plastic or a plastic composite material; the bottom drum, the top drum, the means for clarification.
    [007] The medium for clarifying a product to be processed - to be clarified - from solid particles is preferably a package of separating discs from tapered plastic separating discs, but it can also be, for example, a supplementary part clarification / separation material according to the type of document DE 10 2008 052 630 A1 or another means for clarifying a solid particulate product, such as a ribbed body with radial ribs or the like.
    [008] Consequently, a part and, preferably, even all the regions in contact with the product of the rotary system consist of a plastic or a plastic composite material, particularly the bottom drum part and also the top part and the disc pack. In a particularly preferred manner, the supply system and the discharge system further consist of plastic or a plastic composite material.
    [009] In this way, it is possible to configure a part of the drum or, preferably, the entire drum - preferably, together with the systems and regions of supply and discharge - for a single use, which is of interest and advantage, particularly gnocchi refers to the processing of pharmaceutical products, such as fermentation broths or the like, since after the operation for processing a batch of corresponding product, in the operation of continuous preference, during the processing of the product batch, no cleaning the drum, but the drum must be replaced in total. Hygienic problems associated with cleaning are thus simply excluded. The parts in contact with the product can be totally discarded or recycled. Disposal is of interest, particularly in the case of hazardous substances.
    [0010] In a product clarification process, it is also conceivable to concentrate very heavy substances and to melt the drum after processing a batch or to dissolve it, for example, in an acid or similar, to obtain the heavy substance as a residue of that process.
    [0011] By using plastic parts, in addition, production costs can be kept relatively small.
    [0012] Preferably, the drum is rotatable with a spindle construction, which preferably consists of a plastic or a composite plastic material and which is preferably coupled directly with the secondary axis of an engine, being that the spindle construction does not have any articulated support on its external perimeter. This construction is simple and robust and very well suited for light drum construction. The function of the drum support is assumed in a simple way by the electric motor or its rotor support.
    [0013] In this case, it is advantageous, as well as particularly hygienic, when the whole drum, particularly, also its feeding system and its discharge system, is / are formed in airtight construction mode.
    [0014] According to an advantageous improvement, the drum is surrounded by a housing, which preferably also consists of plastic or a plastic composite material. It is even possible that the entire separator consists, except for the motor, in plastic, so that it can be exchanged in total, except for the motor, preferably, as a pre-assembled unit.
    [0015] According to a particularly advantageous improvement of the invention, the bottom of the drum is provided directly, in one piece, with an additional distributor part, which has one or more distributor channels for transferring the product to be processed from a tube. supply to the internal drum space. In this way, two components or even groups of components are unified, normally produced separately, which makes it possible, particularly, to produce plastic.
    [0016] Preferably, as a plastic, recyclable plastic is used, particularly PE (polyethylene), PP (polypropylene) or TK-PEEK (particularly polyetheretherketone (particularly semicrystalline).
    [0017] The plastic parts can be produced in the die-casting process and, optionally, be finished, for example, equipped with holes or the like, where necessary.
    [0018] Screws and the like can also consist of plastic, but they can also be produced from another material, particularly when they do not come into contact with the product.
    [0019] It seems particularly advantageous to operate the rotary system in subcritical rotation numbers (below the first resonance frequency of the rotary system), since this drive clearly simplifies the drive system and, due to the material selection, this separator, in comparison with other currently common separators, it is operated in other ranges of speeds.
    [0020] The energy requirement can be low, in general, in relation to existing buildings. Due to the low speed, in addition, the noise emission is correspondingly low.
    [0021] With the invention a use of a separator according to the invention is also created as a disposable separation for processing once a batch of product, the separator, without being activated, after processing that batch of product is , preferably discarded, for example, by professional combustion, for example, to discard dangerous substances.
    [0022] The invention also creates a process for operating a separator according to the invention. In this process, in a product clarification procedure, substances are concentrated that accumulate in the internal space of the drum, in the region of the largest internal perimeter. Then, the drum is disintegrated, after the processing of a batch - for example, burnt or melted or for example, dissolved in an acid or the like - to obtain the heavy substance as a residue from this procedure.
    [0023] If solid substances are so compacted that they cannot be discharged or only with great difficulty, or the solid discharge holes clog or become blocked, there is the possibility of dissolving, from time to time, or, if necessary , over the discharge system (discharge unit and, optionally, holes in the drum cover) by quick washing with a medium (water, clarified product, buffer solution, ...) or dilute them again, so that despite In addition, they can be discharged through the emptying holes.
    [0024] Other advantageous configurations can be found in the remaining secondary claims.
    [0025] Next, the invention is described in more detail by means of modality examples, with reference to the figures. Show:
    [0026] Fig. 1 is a view of a separator according to the invention, with a direct drive and with a cut-out carcass and drum.
    [0027] Fig. 1 shows a section through the region of the housing 1 and the drum 2 of a separator according to the invention, with which a liquid product can be separated in two phases in the centrifugal field. The housing 1 has an upper housing part 1a (approximately in the manner of a semi-spherical segment) and a corresponding lower housing part 1b, which are connected here, exemplarily with screws 1c in a flange section. The housing can consist of plastic or a plastic composite material.
    [0028] The drum 2 has a vertical axis of rotation D and is inserted here on a spindle construction 3 in the form of a sleeve - here, in the form of a simple construction), which is coupled here directly or through gear elements interspersed with a drive motor 4.
    [0029] A particularly compact form of construction obtained when the drive motor is an electric motor 4, which is arranged directly on the axial extension of the spindle construction 3, preferably on the side of the spindle construction 3 away from the drum.
    [0030] Here, spindle 3 is directly connected with a pin 16 with a secondary axis 5. In addition, it is rigidly connected to the torsion with a torque transmission medium, here, an adjustment spring 17, in the direction circumferential with the secondary axis of the electric motor 4. The torque transmission medium can also be formed in another form, - for example, as a torque transmission contour - (not shown here). The rotating drum 2 can be connected with a pressed fit (for example, in a conical section) to the drive spindle construction 3 or via another means of torque transmission (not shown here).
    [0031] In this case, preferably, a proper support for the construction of spindle 3 is dispensed, which makes the construction to be carried out in a simple and relatively economical way. The secondary shaft support 5 in the motor housing 6 of the electric motor 4, however, also preferably serves as a support for the entire rotor system, consisting of secondary shaft 5, spindle construction 3 and drum 2.
    [0032] The motor 3 is fixed, here, on its side facing the spindle 3, still, in a flange section 18 of the housing 1, for example, screwed with threaded pins 40. The housing or the flange section, for example in turn, they can be fixed in a way not shown here, for example, by screwing, to a foundation or machine chassis, not shown here, or similar.
    [0033] Drum 2 has a lower part of tapered drum 7 and an upper part of tapered drum 8, so that, in total, a double tapered body is formed. The lower part of the drum 7 and the upper part of the drum 8 are screwed together in the region of its largest circumference by means of threaded pins 9 distributed over the circumference. The connection, however, could also take place in another way, such as with a kind of bayonet closure between the two parts or by screwing, with a separate closure ring, similar to metal separators. A triple clamp connection (tight ring with conical surfaces) would also be conceivable. A kind of retaining ring would also be conceivable, for attaching one drum part to the other.
    [0034] To a section 10, here below, of the lower part of the drum 7 an additional distributor part 11 is axially attached, which coaxially encircles the rotation axis in one part, which forms a complete distributor for introducing the centrifuge material into the internal space of drum 15 and for acceleration the centrifuge material in the circumferential direction, in the rotations of drum 2.
    [0035] In the additional distributor part 11, a hole 12 is formed in the upper region in the manner of a blind hole, into which a feed tube 13 comes out. The feed tube is sealed at its outer perimeter with a first circumferential seal (for example, an O) ring 14 in relation to the internal perimeter of the hole 12.
    [0036] The supply tube 13 and the additional distributor part 11 thus preferably form a supply system, advantageously configured hermetically in relation to the environment.
    [0037] The hole 12 leaves, still, in its lower end, in one or more distribution channels 19, which are formed obliquely to the axis of rotation and leave here, also obliquely in the internal space of the drum 15.
    [0038] In the inner space of drum 15, means for clarification are arranged, such as, in particular, a disc pack 20 in one piece or, preferably, in multiple parts, which is formed as a stack of dividing discs 20 'axially spaced , which have a basic conical shape and are preferably inserted rigidly to twist over the additional distributor piece 11. The means for clarification can also be formed in another form, such as ribbed bodies, with radial ribs or arched or as an additional clarification piece, with clarification chambers.
    [0039] The dividing discs 20 'preferably have different radii here, in each case, which is determined by the basic conical shape of the drum bottom 7, as the dividing discs 20' preferably extend externally until just before the inner edge of the drum bottom 7, so that its diameter decreases correspondingly, from top to bottom.
    [0040] A product introduced into the internal space of drum 15 is separated into drum 2 in several, preferably two, phases of product with different density.
    [0041] For the discharge of the various product phases of drum 2, a drainage system is used, with two or more drainage regions.
    [0042] Thus, a lighter liquid phase flows radially inwards and there is guided in a channel 21 in the additional distributor part 11 axially upwards, to an annular channel 22, which is formed between the outer perimeter of the feed tube 13 and a piece of tube 23 of a larger diameter, which also protrudes from above on drum 2.
    [0043] A heavier liquid phase (or a solid phase, still only at the creep limit) is guided, on the other hand, from the region of the larger inner perimeter of the inner drum space through a channel 25 in the upper part of drum 8, and, more precisely, up to a second annular channel 26 between the outer piece of tube 23 and a drum cover 27, which preferably also consists of plastic.
    [0044] The heaviest and the lightest liquid phase run from the annular channels 22, 26 upwards, in each case, in annular chambers 28, 29 axially arranged over each other, in annular bodies 30, 31, which are equipped with discharges 32, 33 radial, by which the lightest and heaviest discharged phase can be discharged additionally. Further upwards, an annular cover 34 is arranged over the annular body 33, with a through hole 35 for introducing liquid into the supply tube 13. The elements 30, 31,34 preferably also consist of plastic.
    [0045] Between the inner feed tube and the annular body 31 or the cover 34, a first annular seal 36 is arranged. Between the piece of outer tube 23 and the annular body 31, yet another annular seal 37 is arranged. furthermore, between the cover 27 and the lower annular body, another annular seal 38 is arranged.
    [0046] The housing 1, the annular bodies 30, 31 and the cover 34 are here clamped together, simply, axially, compactly and securely, with one or more pins, particularly threaded pins 39.
    [0047] Particularly in the manner shown or otherwise, the supply system, as well as the discharge system, with at least two discharges and, therefore, the entire drum 2, are configured hermetically sealed, so that the product does not comes into contact with the surroundings of the drum and is compressed by the rotating system.
    [0048] In this case, a part or, preferably, even all the regions in contact with the product of the rotary system, consist of a plastic or a plastic composite material, particularly the lower part of drum 7 and the upper part of drum 8. Particularly preferably, the dividing discs 20 also consist of plastic, as well as all regions in contact with the product of the supply system and the discharge system, even when they are not rotating in operation.
    [0049] In addition, it is also possible and advantageous to produce housing 1 of plastic or a plastic composite material.
    [0050] In this way, the construction is very light and can be discarded after processing a sufficiently large batch of product.
    [0051] Fig. 1 shows a modality as a two-stage dividing machine (separation of a product in the "liquid / liquid" phases), with the second liquid phase being discharged through the drum cover 8.
    [0052] Three-phase machines (for separation into three phases) can also be made (not shown here).
    [0053] In an advantageous and simple way, the whole drum 2, together with the supply and discharge system and, optionally, a part of the housing, the upper part of housing 1a, is configured as a pre-assembled exchangeable module or a material composed of plastic.
