Abstract
A plate filter press with chamber plates and diaphragm carrier plates and diaphragms secured thereto is provided that makes it possible to provide an adequately large, radial slurry admission cross-section that remains free of blockage. An annular supporting collar that respectively embraces the aperture edge of the chamber plate and has a U-shaped cross-section in its edge region is arranged in the central flow-through opening of every chamber plate, whereby the end of each U-leg comprises an annular seating wedge for supporting the arched diaphragm. The seating wedge extends in the direction of the respectively neighboring diaphragm and does not constrict the radial flow channel to the respective filter space.
