  • Patent number: 5449468
    Abstract: In a chamber filter press (11), two respective filter cloths (13), which enclose a filter plate (12) located therebetween, are fastened on said plate by means of a connecting part (18) and on the underside (19) thereof by means of lashings (14). The filter cloths (13) are free laterally with respect to the filter plates (12) and, when the chamber filter press (11) is open, they can be stretched apart from one another. The upper ends of the filter cloths (13) are provided with eyelets (20). In this arrangement, two adjacent filter cloths (13', 13") are fastened together on a series (21') of springs (21) which, for their part, are suspended on a mobile crossmember (22). The latter is supported on the chamber filter press such that it can be displaced parallel to the charging channel (17) and can move vertically. It is preferably supported on sliding guides or rails (23) which, for their part, may be supported on the chamber filter press (11) such that they can move in the vertical direction.
