Problems solved by technology

[0002] The traditional processing method of polypropylene plastic filter plate needs to heat and melt the polypropylene granular raw material with a plastic extruder, and then put a certain amount of molten material into the mold for pressing and molding. During the cooling and shaping process, the four sides of the filter plate Due to uneven cooling, the surface is uneven. In order to ensure the flatness of the filter plate sealing surface, the traditional method is to use mechanical cutting to mill the uneven part, which requires the investment of CNC milling machines and a lot of manpower. At the same time, a large amount of cutting waste is caused. During the reuse process, the filter cloth is wrapped on the surface of the filter plate. When the material bonded by the filter cloth on the sealing surface of the filter plate is not cleaned, the local position of the sealing surface of the filter plate is difficult. Compress the seal, so that the slurry will be sprayed during the filtration process, which not only wastes raw materials but also pollutes the environment. In order to ensure the sealing performance of the filter plate, the traditional method is to mill grooves on the sealing surface of the filter plate, and then insert rubber Strips to achieve the sealing effect are also very cumbersome and require a lot of manpower

Abstract

The invention belongs to a filter element of a filter press and one of the major structures of the filter press, and specifically relates to a machining-free sealed square polypropylene filter plate. The machining-free sealed square polypropylene filter plate comprises a filter plate body. The machining-free sealed square polypropylene filter plate is characterized in that an upper straight groove, an upper annular groove, a lower straight groove, a lower annular groove, a big triangular concave surface, a small triangular concave surface, an upper straight convex rib, an upper annular convex rib, a lower straight convex rib, a lower annular convex rib, a big concave surface and a circular hole are distributed on the surface of the filter plate. Compared with the traditional machined filter plate, the machining-free sealed square polypropylene filter plate has the advantages that mechanical cutting and processing of the sealed plane and the rubber strip sealing groove of the filter plate are omitted, lots of manpower, equipment and material resources are saved, and a huge technological advance is realized for a plastic filter manufactured by the traditional method.
