In order that higher demands on the purity of the separated liquid can be satisfied, a cleaning plant (12) having wash chambers (13a,b) for the cleaning of the filter plates (8) is arranged in longitudinal direction alongside of a filter press (1). By means of a transport device (30) having a displacement device (32) which is moveable along rails (31a) and is equipped with a raisable and lowerable gripper (37) which can be engaged via pawls with filter plates (8), the filter plates, after the opening of the filter press (1), are transported one after the other into the cleaning plant (12), sprayed in one of the wash chambers (13a, b) with simultaneous drawing off of the air or subjected to an immersion bath, possibly disinfected or impregnated, dried and transported back. By the development of the cleaning plant (12) with two wash chambers (13a, b), idle paths of the displacement device (32) are substantially avoided. The relative arrangement selected for the filter press ( 1) and the cleaning plant (12) makes it possible to design the transport device (30) in simple manner.

Filter press and cleaning means therefor

A filter press having a plurality of plates adapted to be arranged in abutting relationship in an operating position and to be separated from the operating position for cleansing, replacement or the like, having a pair of first and second reciprocable conveyors arranged respectively along opposing side edges of the plates. Each of said first and second conveyors carry first and second members respectively for engaging the plates selectively during movement of said conveyors, so that when moved in one direction each of the first conveyors and first engaging members act to move the first of said plates from the operating position while each of the second conveyors and second engaging members when moved in an opposite direction act to retain the second of the plates in the operating position.
