Abstract: The invention relates to a filter press construction of the type having a plurality of filter plates suspended from two parallel I beam carriers, the filter plates being provided with a novel supporting arm suspension which prevents undesired swinging. The supporting arms are bent to diverge on both front and back sides of the filter plates, two arms on each side of the vertical center of the plate to provide a novel suspension consisting of two leading bent arms and two lagging bent arms for each filter plate in its operating condition suspended for movement on the I beam carrier. The arms of the filter plates are provided with roller or equivalent sliding elements to facilitate shifting movement on the guiding flange surface of the parallel I beam carriers. This unique leading and lagging supporting arm construction on the I beam carrier eliminates serious swinging problems encountered with conventional filter presses using the parallel I beam carrier suspension for the filter plates.

Abstract: The invention relates to a movable apparatus for removal of filter plates from a filter press, these plates resting on two horizontal guide carriers. The apparatus has a carriage, movable on the guide carriers, which has a driving apparatus for a driver means, in order to always pull off the outside filter plate from a pack of filter plates, and a bolt for holding back the remaining filter plates in the pack. The driver means and bolt are arranged in such manner that the driver means and bolt are movable up and down between a lower engaging position aligned with stops on the sides of the filter plates and an upper dis-engaging position away from such stops.

Abstract: A filter press with a novel spray washing arrangement for the filter plates which plates are shiftable on horizontal guides. The novel spray washing means comprises a carrier frame encompassing the stack of plates together with the horizontal guides and a spray pipe. The carrier frame is movable along the stack of filter plates at vertical, lateral struts. The spray pipe is equipped with spray nozzle and is guided as a unit movably up and down along the vertical struts. The spray pipe comprises two branch lines enclosing between them a filter plate that is to be spray washed. The spray nozzles of the two branch lines face each other to provide the same pressure on front and back surfaces of the filter plate.
