ABSTRACT:
This invention relates to filter presses of the kind comprising a plurality of separate filter plates which are supported by or from a main frame so as to form a stack at one end of the frame during a filtering operation, and which are arranged to be moved one by one towards the opposite end of the frame to enable filter cakes to be removed from between the plates.
The plates are heavy and tend to stick together, and known mechanism for moving the plates individually is either complex and tends to clog with the clay or like being filtered in ordinary usage, or fails to take account of the sticktion resulting in the press jamming.
In the invention, the first plate in the stack which is not to be moved is held in place by a pawl engaged with a rack, and a reciprocating carriage moves across the gap between the open and unopen plates of the stack, shutting the pawl and displacing it to engage with the next plate in the unopen part of the stack and then picking up the released plate and displacing it to the opened part, once in each cycle.
