ABSTRACT:
A filter press includes a plurality of filter elements (filter plates and filter frames) supported in the press stand for displacement along the length of the press. A guide roller is supported on each filter element alternatingly at opposite sides thereof. A continuous filter cloth is trained about each guide roller for guiding the filter cloth in a zigzag course between all adjoining filter elements. At least some of the guide rollers are directly driven by a driving mechanism. The driving mechanism has a sprocket drivingly connected with each driven guide roller and having a rotary axis in alignment with the rotary axis of the associated driven guide roller and a guide wheel mounted on each filter element which supports a driven guide roller. Each guide wheel has a rotary axis spaced parallel from the rotary axis of the respective sprocket. The driving mechanism further has an endless flexible drive member meshing in succession with each sprocket and being deflected by the respective guide wheels between every adjoining sprocket, whereby the flexible drive member has a zigzag course.
