Apparatus for regenerating filter clothes of filter press

A filter press comprising:

• a pair of vertical frame members;
• a pair of horizontal guide rails;
• wherein one guide rail interconnects said frame members on one lateral side thereof and the other guide rail interconnects said frame members on the other lateral side thereof;
• a plurality of filter cloths each having a pair of upper ends;
• a plurality of filter plates each having opposed vertically oriented filtering surfaces, the plates movably disposed in parallel on the guide rails, each of the filter clothes covering the opposed filtering surfaces of a respective one of the filter plates;
• a plurality of horizontal upper-portion support bars each having two ends, wherein each said support bars is disposed directly above and is parallel to the filtering surfaces of a respective one of the filter plates;
• means for resiliently connecting each said support bar to an upper end of a respective said filter plate;
• connecting means for connecting the upper ends of each said filter cloth to a respective one of said support bars so that the filter cloth covers the opposed filtering surfaces of a respective filter plate;
• an opening and closing mechanism for connecting the filter plates to one another and simultaneously opening or closing a plurality of the filter plates;
• wherein filtering chambers are formed between adjacent filtering surfaces of adjacent filter plates when the filter plates are closed and which are opened when the filter plates are opened;
• a horizontal main supply pipe for supplying washing water connected to one lateral side of said frame members and extending parallel to said guide rails and located above the upper-portion support bars;
• a support pipe connected to the other lateral side of said frame members and extending parallel to said guide rails and located above the upper-portion support bars;
• washing pipes disposed above and extending parallel to the upper-portion support bars and extending between the supply pipe and the support pipe, each of the washing pipes disposed above a gap between the filter plates when opened;
• first connecting members, each of which pivotably connects one end of each of the washing pipes with the main supply pipe;
• second connecting members, each of which detachably connects the other end of the washing pipe with the support pipe;
• flexible pipes, each of which connects the main supply pipe and a respective one of the washing pipes to each other in a communicated state so as to supply washing water from the main supply pipe to each of the washing pipes;
• nozzles provided for each of the washing pipes to spray washing water to each of the filter cloths;
• and
• a pair of vibration rods for vibrating the upper portion-support bars, one of the vibration rods being connected to one lateral side of the frame members for contact with one of the ends of the support bars and the other vibration rod being connected to the other lateral side of the frame members for contact with the other end of the support bars.
