Abstract: A membrane plate for a filter press includes a plate member composed of a plate wall having a peripheral region provided with a plate wall groove and a plate frame surrounding the plate wall. A flexible press membrane is disposed adjacent at least one side of the plate wall and a holding frame covers a membrane edge bead received in the plate wall groove. A connecting arrangement secures the holding frame to the plate frame and permits transverse movement of the holding frame with respect to the plate wall. The connecting arrangement includes a continuous peripheral groove in the plate frame and a continuous, elastic member supported on the holding frame. The elastic member projects from the holding frame and is received by the continuous peripheral groove.

Abstract: A plate filter press includes a plurality of face-to-face arranged filter plates movable into open and closed positions. Any two adjoining filter plates together define a filter chamber bounded by a continuous, raised sealing edge carried on at least one of the two adjoining filter plates. Separate heavy liquid intake members constituted by tubular bars are in fluid communication with each filter chamber. The sealing edges are provided with a respective recess extending in a longitudinal direction of the sealing edges. The tubular bars extend in the longitudinal direction and are sealingly received in the respective recesses in the closed position. Each tubular bar has a liquid outlet opening, and each sealing edge is provided with a transverse liquid passage situated between the recess and the filter chamber.

Abstract: The invention relates to a filter plate for a plate filter press with at least one press diaphragm (6) covered with filter fabric, in which the filter plate (2) and the press diaphragm (6) have at least one shared passage aperture (4), whereby the edge of the aperture (4) of the press diaphragm (6) has a circumferential edge bead (9) which is held in a groove (10) at the edge of the aperture (4) of the filter plate (2) by means of an annular securing component so as to create a seal.
