Abstract: The invention provides a filter press comprising a support frame; a plurality of filter plates mounted adjacent one another on the support frame, the filter plates being displaceable between an inoperative position wherein adjacent filter plates are spaced apart, and an operative position wherein adjacent filter plates abut to form filtration cavities between them; the filter plates in their inoperative position being angularly displaceable relative to the support frame; and actuating means adapted angularly to displace the filter plates relative to the support frame so as to discharge filter cake from the filtration cavities.

Abstract: The invention provides a novel filter press comprising: a support frame; a plurality of filter plates mounted adjacent one another on the support frame, the filter plates being displaceable between an inoperative position wherein adjacent filter plates are spaced apart, and an operative position wherein adjacent filter plates abut to form filtration cavities between abutting filter plates; a backing arrangement located adjacent an outermost filter plate, the backing arrangement being displaceable relative to the support frame and being releasably lockable in a fixed position relative to the support frame; and a pressure exerting mechanism adapted to force the filter plates in co-operation with the backing arrangement into sealing abutment when the filter plates are in an operative position and the backing arrangement is releasably locked relative to the support frame.
