摘要:
A pressure filter includes a pressure vessel having a pressure chamber and a circumferential edge; a turntable rotatably mounted within the pressure vessel about a horizontal axis; a plurality of filters non-rotatably mounted to the turntable and spaced apart from each other at the circumferential edge of the pressure vessel and rotatable around the horizontal axis through a center of the pressure vessel such that the plurality of the filters continuously dip into and out of a solid solution in a bottom of the pressure chamber. A blow-off station is positioned above the solid suspension in the pressure chamber for freeing filter cake that has dried on the plurality of filters. A filter cake conveyor conveys the blown-off filter cake through a pressure lock in the pressure vessel. Each filter forms a filter element having a filter surface which is defined by cross-section sides extending along a radius of the pressure vessel adjacent to the circumferential edge, and long sides extending parallel to the horizontal axis of pressure vessel.

A filter press operating under pressure including a vessel (1) filled with crude material with compressed fluid lying above. A hollow shaft projects into the vessel and supports an assembly of filter elements immersed in the crude material. At least one drying and removing unit for the filter cake is mounted in the vessel above the crude material, into which the filter elements are brought in succession. Driving means are provided for imparting a stepwise movement to the filter elements to the filter assembly and a raising and lowering movement to the individual filter elements with respect to the drying and removing unit.
摘要:
A filtering apparatus for batchwise operation in which a tank contains filter means in the path of liquid to be filtered the downstream side of the filter means communicating with a filtrate collector and jets for directing a liquid on to the filter means after a batch has been processed, to dislodge the extract from the filter means.

1,181,273. Liquid filter. G. MAESTRELLI. 15 June, 1967 [15 Feb., 1967], No. 27618/67. Heading B1D. [Also in Divisions D1 and D2] A filter used in the solvent circuit of a coin-freed dry-cleaning machine comprises a plurality of filter elements D, made of wire wound on flat frames of moulded plastics, having lozenge-shaped cross-sections and being radially arranged about and supported by two or three rotatable hollow shafts F. After a washing cycle, during which solvent passes continually through the filter and back to the washing tub, the solvent flow is stopped and the shafts are rotated or arcuately reciprocated by a common motor (64), creating turbulence in the dirty solvent around the elements and thereby washing the used, absorbent, filter aid and solids therefrom. Periodically a sludge outlet (72) in the housing floor is opened. In Fig. 2 and Fig. 3 (not shown) the elements D intermesh and turbulence is concentrated in zone H. In Fig. 4 (not shown) the elements of the different assemblies do not intermesh and there is less turbulence. Within the limits of the filter housing, additional filter elements may be added to each ring of elements, and further complete rings of elements may be mounted axially above the first on each rotatable assembly. The ends of elements open into hollow radial arms of plastics spiders between which elements are clamped, the spiders (G) open into the interiors of shafts F and these discharge filtrate by outlets (70). Sludge discharged by outlet (72) passes to a distillation plant which recovers the filter aid.

A device is provided for cleaning a filter cloth that forms a part of a filter element in a rotary disc filter. The device includes a flush tube and a spray nozzle operatively connected to the flush tube for receiving a cleaning fluid from the flush tube and directing the cleaning fluid onto the filter cloth.

A disc filter sector comprising a trapezium tubular support frame, and a trapezium screen frame supporting a screen cloth, the trapezium filter medium element being connected to the trapezium tubular support structure. More particularly, there is a pair of such filter sectors, and the sectors are connected together by an overlying cap.
