  • Filter plate-and-diaphragm assemblies for a filter press
    Patent number: 3931014
    Abstract: In a filter plate-and-diaphragm assembly, the marginal sealing zone of the diaphragm has a sealing rib received in a groove of the filter plate frame. During operation, the diaphragm, with the exception of the sealing zone, is lifted off the filter plate by a pressure medium introduced in a pressure chamber bounded by the diaphragm. The rib is situated in the vicinity of that edge of the sealing zone that is remote from the pressure chamber, so that an intermediate sealing zone of considerable width is disposed between the rib and the pressure chamber.
