- This international search report has been prepared by the International Searching Authority and will be transmitted to the applicant in accordance with Article 18. A copy will be sent to the International Office.
- This international search report comprises a total. Leaves. In addition, he is accompanied by a copy of the state-of-the-art documents mentioned in this report. 1.
- the international search was carried out on the basis of a translation of the international application submitted to the authority (Rule 23.1 b)). * ⁇ ⁇ With regard to the nucleotide and / or amino acid sequence disclosed in the international application, see field no. 2.
- the invention relates to a centrifuge with a rotatable centrifugal drum which has a plate pack.
- Such separators are known in a wide variety of embodiments, e.g. from DE 200 10 743 Ul.
- the object of the invention is to improve this prior art by creating separators with at least partially improved properties and preferably new possible uses.
- the invention solves this problem by means of the subject matter of claim 1 and creates a new type of centrifuge which has advantages over the prior art in a wide variety of products.
- the centrifuge has at least two centrifugal drums, each of which can be rotated about two axes of rotation, only one of the axes of rotation passing through the center of gravity of the centrifugal drums, such that one of the axes of rotation in each case within the at least one or more centrifugal drums (n ) and the other axis of rotation outside the centrifugal drum (s), the two axes of rotation running through the center of gravity preferably being aligned parallel to one another - in particular lying in one plane - and with a set of plates each being inserted into the drums.
- DE 3 092 579 also shows an emptying system for open drums that can be rotated about an axis of symmetry and are tilted during emptying about a second axis that runs through the one drum.
- DE 1 432 853 OS shows a method and a device for separating substances by gyrofugation, in which a drum is rotated about its axis of symmetry and moved about a further axis on a circular ring which is inclined by approximately 45 ° to the axis of symmetry.
- separators with more than one drum each having one of the plate packs and drums rotatable about more than one axis of rotation, are not disclosed or suggested in the prior art.
- the centrifuge has two - or even more - centrifugal drums, again preferably one of the axes of rotation lies within the at least one or more centrifugal drums and the further axis of rotation preferably outside of the
- Centrifuges result in a centrifuge that is easier to balance than a centrifuge with only one centrifugal drum, which is necessary because the further axis of rotation lies outside the centrifuge drum.
- the first axes of rotation of the drums lie within the drums and coincide with an axis of symmetry of the drums, the second axes of rotation crossing the first axes of rotation perpendicularly.
- This arrangement can be achieved, for example, by a dumbbell-like distribution of the drums, the axis of symmetry of the drums each representing the first axis of rotation and the two drums being rotated like a dumbbell about the second axis of rotation.
- the solid is conveyed to the outside in a simple manner by the rotation of the two drums about the common second axis of rotation, without the need for auxiliary means.
- the Telle ⁇ akete have an advantageous clarifying effect, since they rotate about the first axis of rotation.
- the two centrifugal drums preferably have a double-conical structure, two conical sections oriented opposite one another being formed in each case on the end region which is inner relative to the second axis of rotation and on the end region which is outer relative to the axis of rotation of the centrifugal drums. It is a good idea if the two conical sections of each ScMuder drum are connected to each other via cylindrical sections.
- one of the plate packs with conical plates and preferably riser channels is arranged concentrically to the feed pipe in both centrifugal drums.
- the Telle ⁇ aket solid is separated from the feed or centrifuged material and collects in the solid space (cylindrical) of the centrifugal drum. The solid is then conveyed to the outside by the rotation about the second axis A2.
- This construction makes it possible for the solids to be removed completely automatically by rotating the two drums about the common second axis of rotation. Use of the system for clarification is conceivable
- the effect of the Telle ⁇ akete is due to the rotation around the first axis as with a normal separator.
- the Telle ⁇ aket can also have plates in height.
- the speed on the first axis corresponds to that of a separator.
- FIG. 1 shows a section through a centrifuge according to the invention. and FIG. 2 shows a top view of the exemplary embodiment of FIG. 1.
- Fig. 1 shows a centrifuge 1, which has two centrifugal drums 2, 3, which are each rotatable about a first axis of rotation AI, here a horizontal axis of rotation.
- the first axes of rotation AI pass through the centrifugal drums 2, 3 each as axes of symmetry in their welding points and are aligned here.
- the centrifugal drums 2, 3 are arranged opposite one another. However, the first axes of rotation do not have to be aligned. They can also be aligned in a different way, preferably parallel to one another.
- centrifugal drums 2, 3 are each also rotatable about a second axis of rotation A2, which here lies outside the centrifugal drums 2, 3.
- the two rotary drums 2 are rotated "as a whole” together around the second axis of rotation A2 lying outside the rotary drum 2 - preferably in the common center of gravity of the rotary drums 2, 3 - which is perpendicular to the first axis of rotation AI and crosses them.
- the centrifugal drums 2, 3 here have a double-conical structure, two conical sections 4, 5 oriented opposite to each other being formed on the inner end region relative to the second axis of rotation A2 and on the outer end region of the centrifugal drums 2, 3 relative to the second axis of rotation A2 and are connected to each other via central cylindrical sections 6.
- the centrifugal drums In the area of sections 4, 5, 6, the centrifugal drums here have a continuous jacket.
- discharge openings 7 are formed, in particular for a solid phase, which are aligned concentrically with the first axis of rotation AI.
- the outer conical sections 5 are each preferably conical at an acute angle relative to the first axis of rotation AI, the conicity angle ⁇ to the first axis of rotation being 60 ° and less, so that wear effects due to solids emerging from the nozzles on the drum jacket be avoided. This angle ⁇ is warmed so that the solid can advantageously slide off at this angle.
- the inner conical sections 4 are followed by cylindrical projections 8 towards the second axis of rotation A2, which are rotatably supported in bearing elements 10 by means of bearing systems, in particular by means of suitable ball bearings 9, which absorb axial and radial forces. It is also conceivable to provide additional storage systems (not shown here) in the outer area of the centrifugal drums (e.g. following the conical areas on cylindrical projections or the like (not shown here)).
- the function of supply pipe 11 and discharge ducts 12 can also be reversed - with appropriate modification of the connections). It is also conceivable to connect the two rotary drum drums one behind the other in terms of flow technology.
- Pulleys 13 are attached to the cylindrical lugs 8, which are connected via drive belts 14 to output shafts 15 of first drive devices 16, in particular electric motors or hydraulic motors, which are preferably arranged parallel to the scuder drums 2 on opposite sides of the centrifugal drums 2 in order to realize an arrangement that is as unbalanced as possible.
- first drive devices 16 in particular electric motors or hydraulic motors, which are preferably arranged parallel to the scuder drums 2 on opposite sides of the centrifugal drums 2 in order to realize an arrangement that is as unbalanced as possible.
- a belt drive e.g. with flat belts, V-belts or toothed belts
- chain drives or direct-acting transmissions such as gear transmissions or the like are conceivable.
- Centrifugal drums 2, 3 are arranged on a rotatable, carrier-like ring 17, through the center of which the second axis of rotation A2 runs, the centrifugal drums 2, 3 above and the first drive devices 16 below the ring 17 are located. It is also conceivable to arrange the centrifugal drums 2, 3 between an upper and a lower ring (not shown here) or to also arrange the drive devices above the ring 17 (also not shown here). Finally, the two centrifugal drums 2, 3 could also have a common drive device 16 for driving the centrifugal drums 2, 3 about the first axis of rotation AI, for example a drive motor with two pulleys on a common output shaft or the like.
- the horizontally aligned ring 17 is rotatably mounted on a base frame 19 with bearings 18 and can be rotated on the base frame 19 by means of a second drive device 20.
- the bearing 18 absorbs both the axial and the radial forces and can also be realized in another way.
- a Telle package 21 with conical plates is arranged in both centrifugal drums 2, 3, concentrically to the inlet pipe 10, which can be provided with riser channels 22 and can have a structure analogous to that of separators.
- both centrifugal drums 2, 3 rotate at a higher first speed about the first axis of rotation AI.
- One of the decanters or even separators of known circumferential speed about the first axis of rotation AI at the outer drum diameter can be reached, e.g. a peripheral speed of meM than 80m / sec, whereas the two centrifugal drums 2, 3 preferably rotate about the second axis of rotation A2 at a lower peripheral speed (subcritical operation is preferred).
- Subcritical operation means a speed below the first resonance frequency of the separator.
- the centrifugal material supplied by the feed pipe 11 enters the centrifugal drums 2, 3, where the liquids of different densities collect on different radii and are discharged through one or more discharge pipes or peeling discs or the like. 1, only one liquid phase is derived in each centrifugal drum 2, 3.
- the solid phases collect on the inner circumference of the centrifugal drums 2, 3 and, as a result of the rotation of the centrifugal drums 2, 3, migrate outward about the second axis of rotation A2, where they migrate out of the centrifugal drums in the outer conical sections 5 to the discharge openings 7 and collected in a manner not shown (eg in an outer ring-shaped catching device or the like.
