ABSTRACT:
A filter press has a plurality of filter plates which are individually shiftable by a gripper of a moving mechanism. The filter plates can be releasably locked to one another by a locking hook pivotally supported on each filter plate and engageable behind a detent pin carried by a respective adjoining filter plate. Each filter plate further has a pivotal detent lever operatively connected with the locking hook of the same filter plate and the detent levers of the respective two adjoining filter plates. When the filter plates are close together, the detent levers, by mutual interaction, are pivoted out of the traveling path of the gripper of the moving mechanism. When the head plate of the filter press is moved away from the filter plate stack, a spring can pivot the detent lever of the outermost filter plate in the opposite direction so as to be engageable by the gripper which, prior to shifting the outermost filter plate, pivots the detent lever which it abutted, whereupon the detent lever effects a pivotal motion of the respective associated locking hook, releasing the latter from the detent pin of the adjoining filter plate. Thereafter, the gripper shifts the outermost filter plate away from the other filter plates. This allows the detent lever of the new outermost filter plate to pivot into the gripper path, whereupon the unlocking and shifting cycle is repeated.
