Abstract
A squeeze-filter plate for use in such a filter press as to squeeze a cake of solid substances which is built up within a filtration room defined between the squeeze-filter plate and a filter plate adjacent thereto. The squeeze-filter plate is composed of a diaphragm means having a central portion and an outer peripheral portion, and a frame for supporting the diaphragm means. The outer peripheral portion has at least one structure for discharge a filtered liquid from the surface of the diaphragm to a passage in the frame. This structure is constituted by at least one aperture defined in the outer peripheral portion having a solid plug portion positioned therein and at least one socket member housed in the aperture for defining at least two discharge passages each of which guides a filtered liquid from one of the surfaces of the central portion to the passage in the frame without clogging occurring therein.
