The present invention relates to a method pertaining to press filters of the kind which include a plurality of press plates (13). Pressure chambers (15), are formed between each pair of plates. A filter cake (16) is formed in each pressure chamber. Upon completion of the dewatering process the cakes are released from the chambers by separation of the press plates. The method is characterized in that emptying of the pressure chambers (15) is achieved by permitting each press plate (13) to rotate freely and swing about an axis (18) which extends generally horizontally through the plane of the plate, under the influence of the released filter cake (16). The press filter is constructed so that each press plate (13) is able to pivot in relation to the rails (14). The pulling devices by means of which the press plates are separated are attached to only one single coupling device (19) on each side of each press plate. The coupling devices (19) are placed on or in the immediate vicinity of the runner means, in other words in the proximity of the horizontal rail. <IMAGE> |
