摘要： The present invention relates to a method pertaining to press filters of the kind which include a plurality of press plates that can be brought towards and into mutual abutment and pairs of which form therebetween at least one pressure chamber, wherein there is formed in each pressure chamber as the aqueous suspension of solid particles is dewatered a filter cake which upon completion of the dewatering process is released from the chamber by separating the press plates so that the chamber will empty itself of its contents. The method is characterized in that emptying of the pressure chambers is achieved by permitting each press plate to rotate freely and swing about an axis which extends generally horizontally through the plane of the plate, under the influence of the released filter cake. The press filter is constructed so that each press plate is able to pivot in relation to the rails. The pulling devices by means of which the press plates are separated are attached to only one single coupling device on each side of each press plate, this coupling device being placed on or in the immediate vicinity of the runner means, in other words in the proximity of the horizontal rail.

摘要： The invention relates to a method for dewatering particle collections with the aid of a filter press in a cyclic sequence comprising filling, dewatering and emptying stages. The various stages within each cycle and between consecutive cycles are followed-up and determined by measuring continuously a magnitude which varies with the mass of the press and its contents, preferably the pressure exerted by the press and its contents on the surface supporting the press.

摘要： Method and apparatus for pressure filtering in a pressure filter (1) comprising a frame carrying press plates (3-6), which can be brought together and apart, said press plates between themselves forming pressure chambers (8). In each pressure chamber there are two filter cloths (9) forming a filter element, said filter cloths being connected to each other in one piece and hanging down from a suspension rod (58) resting on guide rails (86). During operation a suspension of solid particles in a liquid is introduced between the filter cloths (9) in the pressure chambers (8). The liquid is pressed through the filter cloths (9) under the influence of membranes (7) loaded by a pressurized medium and by blowing through a gas and is removed through drain channels (10, 12, 14). The filter cakes (40) remaining between the filter cloths (9) are discharged after bringing apart the press plates (3-6) by vibrating (98) of the filter cloths (9). In order to clean the filter cloths (9 ) from solid particles remaining thereon pipelike means (106) mounted on a laterally movable drip pan are inserted between the filter cloths (9) and spray downwardly directed spray jets (36, 48) of washing liquid on the filter cloths.
