[0002] The filter press uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment. The corner feed filter plate is one of the main structures of the filter press. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a rectangular chamber filter plate with the publication number of CN205461197U. The material used for the production of the rectangular chamber filter plate is polypropylene. The outer dimensions of the filter plate produced by a mold are rectangular. The filter chamber and the support platform are made by the mold. The apertures of the undercurrent holes and the feed holes are made by the mold. The size of the mold must have a processing allowance and a shrinkage amount. The filter plate blank is molded by a flat vulcanizer. The molded filter plate blank is taken out of the flat vulcanizer to remove the burrs, and then placed on a flat ground to cool and shrink naturally. It is placed flat for about 24 hours and then turned over to cool the other side naturally. The cooling time is about 24 hours. Then the filter plate blank is placed in a special equipment filter plate shaping machine and pressed and shaped for 24 hours. The filter plate blank is taken out from the shaping machine and placed on the ground for 24 hours as an aging treatment. The machine The equipment used for processing is CNC3190 machining center. A water nozzle is installed at the lower end of the filter plate to connect with the liquid collecting hole and the undercurrent hole. The installed water nozzle can be used for both open flow and undercurrent drainage. The installed water nozzle can timely check the filtration effect of filtrate discharge. The water nozzle is made of extended type. The material used for making it is polypropylene or other plastic materials. The feed hole and the undercurrent hole of the filter plate are machined by the machining center. The drainage hole and the liquid collecting hole are connected, the liquid collecting hole and the undercurrent hole are connected, and the corner drainage hole and the undercurrent hole are connected. The drainage hole and the corner drainage hole are processed by a hand electric drill, and the drilling of the liquid collecting hole is processed by a Z50-16 drilling machine. The process hole of the liquid collecting hole at the upper end of the filter plate is blocked and sealed by friction welding of plastic materials. The corners of the filter plate that has been machined and qualified are blunted to remove burrs, and finally a rectangular chamber filter plate is obtained.

[0004] In the above utility model, the liquid to be filtered enters the interior of the filter chamber through the undercurrent holes and the corner drainage holes, and the two adjacent filter chambers of the two filter plates form a sealed space. The liquid is discharged through the drainage holes, the liquid collecting holes and the water nozzles in sequence, and the filter residue is gathered inside the two adjacent filter chambers. There is no cleaning structure, and it is difficult for the operator to clear out the filter residue inside the filter chamber, which brings inconvenience to the cleaning work of this utility model.
