[0002] The sewage filter press is a mechanical device that uses a special filter medium to exert a certain pressure on the object to make the liquid seep out. It is a commonly used solid-liquid separation equipment used in chemical production. It is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. The filter plate has the advantages of stable performance, convenient operation, safety and labor saving. The metal cylinder is made of seamless steel pipe and the plastic steel filter plate is precision-cast. It is resistant to high temperature and high pressure and is durable.

[0003] The sewage filtered out by the existing sewage filter press is relatively turbid, and an additional device is needed to precipitate the sewage, which is complicated and takes up space. Due to the long-term sewage treatment, various impurities will accumulate inside the existing sewage filter press over time. If not cleaned in time, the accumulated impurities will corrode the inside of the device and affect the service life of the press. Manual cleaning is required, and the machine needs to be disassembled for cleaning, which is time-consuming and laborious. Therefore, a sewage sedimentation filter press device is proposed to address the above problems. Utility Model Content
