Abstract
A chamber filter press for dewatering waste water or product sludges, comprises a press frame with a number of filter plates movably attached at the head bracket and a crosshead that is hydraulically movable for closing the filter plate bundle. The hydraulic cylinder is supported by a replaceable receptacle device in the form of a flange pipe on the end stand of the press frame. Both flanges of the tubular receptacle device are annular flanges, with dimensions matching the flange of the hydraulic cylinder and they have identical through-bores. The flanges are permitted to pass through the hydraulic cylinder and the end stand has on the attachment side a through-hole for the hydraulic cylinder. The receptacle opening has on the opposite side an installation opening through which the back end of the hydraulic cylinder passes.
