[0002] The plate and frame filter press is a common solid-liquid separation equipment, widely used in chemical, mining, metallurgy, food, pharmaceutical and other fields. It is mainly composed of filter plates, filter frames, clamping devices, filter media, etc. When working, the solid-liquid mixture is pumped to the filter chamber, and the solid particles gather on the filter cloth to form a filter cake, while the clean liquid enters the liquid collecting tank through the filter cloth and is finally discharged through the drain port. The clamping device applies pressure to make the filter cake tighter and improve the filtration efficiency. The advantages of the plate and frame filter press include simple operation, applicability to various solid-liquid separation scenarios, large processing capacity, good filtration effect, etc. In addition, the plate and frame filter press can also be automatically controlled as needed to improve production efficiency and stability.

[0003] During the use of the plate and frame filter press, the plate and frame has a major function and is used in the solid-liquid separation process. A filter frame, partition plate, filtrate tank, grid, diaphragm and sealing structure are arranged inside the plate and frame. The sealing structure plays a very important role. However, after long-term use, the seals may lose their elasticity and sealing due to aging and wear, resulting in falling off, thereby causing leakage. The replacement method of the seals around the filter plates in the plate and frame is relatively cumbersome, and the plate and frame and the filter plates need to be repeatedly disassembled and assembled, thereby increasing unnecessary workload.
