    Abstract: A centrifuge includes a conveyor for moving cake along a cake flow path towards a cake discharge opening and further includes a baffle mounted to the conveyor and disposed along the cake flow path. The baffle is provided on an upstream side, facing substantially away from the discharge opening, with a concave profile or surface. This concave profile or surface serves to direct a portion of the cake, which is headed downstream along the cake flow path, into a recirculation or churning path directed partly back towards a pool. The recirculation or churning of the particulate material facilitates an enhanced washing thereof and improves the removal of valuable solutes or undesirable impurities from the cake.

    Abstract: Centrifugal filtration capable of improving recovery of crystal in a baskey. The basket is so arranged that a central axis thereof is inclined with respect to a horizontal direction to obliqely downwardly orientate a bottom wall of the basket. A crystal recovery auction pipe is arranged which includes a pivotally movable section pivotally moved in the basket, of which a distal end is advanced into crystal in the basket. Crystal in the basket is recovered by suction through the distal end of the suction pipe, which is ultimately displaced to a corner of the basket between a lowermost portion of a peripheral wall of the basket and a bottom wall thereof. This permits crystal collected to a lowermost section of the basket to be substantially recovered by suction through the suction pipe, to thereby improve crystal recovery.

    Abstract: Centrifugal apparatus for the continuous separation of solids-liquid mixtures and the internal washing of separated solids is provided with one or more conduits to deliver washing liquid into centrifugally sedimented solids tumbling and suspending these solids in washing liquid. A distal end of each wash conduit is positioned in close proximity to the inner surface of the centrifuge bowl near the conveyor blade which is adapted to contact the solids upon separation and propel separated solids toward the solids discharge port. The invention includes centrifugal apparatus provided with plurality of cutting tools such as knife blades adapted to cut and separate the sedimented solids. In another aspect of the invention centrifugal apparatus is provided with one or more dip weirs dividing the centrifugally separated liquid pool in the bowl into axially adjacent zones with suitable a passageway for transfer of liquids and solids between adjacent zones. In another aspect of the invention at least a portion of the leading surface of the conveyor blade is provided with an arcuate surface portion adjacent to the distal edge thereof of defined concavity in the leading surface and shape adapted to contact the sedimented solids and tumbling them in washing liquid. This invention provides improved separation of mother liquor from discharged solids and/or reduction of washing liquid required to achieve desired purity of recovered solid product.

    Abstract: In order to considerably reduce expenditures for the dewatering of sludges, particularly from sewage treatment facilities, and thereby perform the step from a sticky, wet solid to a flowable solid granulate practically without the re-admixture of material, it is proposed to employ a solid bowl sludge centrifuge as the dispersing member in a subsequently connected convection dryer for further dewatering of the wet solids particles that are ejected with a dry substance content of approximately 25-35 weight percent. The wet solids particles that are ejected at high speed in the form of a film of particles from the outlet of the solid bowl sludge centrifuge are surrounded by the hot drying gas while still on their trajectory and are pre-dried to a dry substance content of approximately 65 weight percent (FIG. 5).

    Abstract: A cup (2) of the centrifuge has two chambers (1,3). In the first chamber is placed the first blood bag (6) filled with blood fluid, which is inserted into the chamber together with an elastically deformable inset cup (4). A pressure pad (9) bears at one end on the outside (7) of the inset cup (4) and at the other end on the inside (8) of the chamber (1) of the centrifuge. During the centrifuging, the pressure pad (9) is admitted with pressure which results in a great volume increase. The inset cup (4) is thus compressed elastically so that the blood bag (6) is compressed and the blood components centrifuged in the blood bag are transferred corresponding to the volume increase of the pressure pad (9) into an empty satellite-blood bag arranged in the adjacent chamber (2). Over the upper connecting part (81) of the blood bag projecting from the chamber (1) is pushed a holder (64) which prevents bending of the connecting tube during the centrifuging process.

    Abstract: A centrifugal separator has a rotary cylindrical basket on which a cake of solids builds up during rotation of the basket. The charge of the basket is controlled by a sensor sensing the thickness of the cake and a vertical manifold sprays a wash fluid on the cake. The washing of the cake is improved by mounting the manifold on a mobile support and linking this support to the sensor so that the position of the manifold is a function of the thickness of the cake.
