Abstract
A plate-type filter press has sidebars carried on fixed frames, and the filter press plates, the queen end and the king end are all supported on the sidebars by means of pins projecting laterally from the plates and the king and queen ends and resting on the bars. The plates and the queen end are able to slide along the bars on their pins, and even the king end is allowed a limited amount of float between stops on the bars. The press is opened and closed by means of double-acting hydraulic piston-and-cylinder units which are mounted on the king end and are coupled to the queen end by longitudinally extending tie rods so as to close the press by pulling the queen end towards the king end.
Claims5
A filter press comprising a pair of fixed side bars extending horizontally one along each side of the press, a stack of filter plates disposed between the side bars and all supported on the side bars for individual sliding movement therealong by means of pins projecting laterally from the sides of the plates and resting on the side bars, a king end and a queen end at opposite ends of said stack of filter plates and each likewise supported on the side bars for individual sliding movement therealong by means of pins projecting laterally from the sides of said king end and said queen end, and
- fluid-operated piston-and-cylinder units mounted on said king end to float therewith on the said side bars,
- said piston-and-cylinder units having their axes parallel to said side bars and being disposed at opposite sides of said king end adjacent interiorly of said side bars and longitudinal tie rods coupling said queen end to said piston-and-cylinder units thereby to close the press by pulling said queen end toward said king end,
- said tie rods being disposed at opposite sides of said stack of filter plates and lying between said stack and said side bars.
