Abstract:
A filter press (1) comprising:a stack of vertically aligned, horizontally displaceable filter plates (6) having sealing edges and sealing surfaces, a plurality of connecting brackets (11) that each respectively have a groove therein and that are respectively connected to respective ones of the filter 8 plates, and a plurality of coupling pins (12) that protrude from the filter plates and that each respectively engage in the groove of a respective one of the connecting brackets that is connected to: an adjacent one of the filter plates, so that adjacent pairs of the filter plates (6) are mutually coupled via at least one of the connecting brackets (11) each and define a respective filter chamber therebetween, with the filter plates (6) lying against one another with the sealing edges thereof contacting the sealing surfaces of adjacent ones of the filter plates in a pressing position of the stack of filter plates and, starting from the pressing position, the filter plates are displaceable successively to a discharge position by a horizontal displacement of at least one of the filter plates (6) in which a horizontal spacing distance of adjacent ones of the filter plates (6) is limited by an action of the coupling pin of a given one of the filter plates (6) contacting on a stop surface (20) of the groove of the connecting bracket (11) of an adjacent one of the filter plates (6) adjacent to the given filter plate, wherein the filter plates (6), starting from the pressing position, can be displaced to a relief position in which the sealing edges of the filter plates (6) are detached from the sealing surfaces of respective adjacent ones of the filter plates and in which the coupling pins (12) respectively contact on blocking surfaces (13) of the grooves of the connecting brackets (11) which prevents further horizontal spacing of adjacent ones of the filter plates, with the contacting of the coupling pins (12) on the blocking surfaces (13) being removable by unlatching the connecting brackets (11), so that a further displacement of adjacent ones of the filter plates (6) to the discharge position is possible.
