[0002] The plate and frame filter press uses a plurality of filter plates and filter media arranged at intervals and pressed against each other to form a closed filter press chamber, a pressing chamber, and a filtrate trough to complete the filtration dehydration. The filter plate in the prior art has a filter frame, a partition, a filtrate trough, a grid, a diaphragm and a sealing structure, among which the sealing structure plays a very important role. As an important solid-liquid separation equipment, the plate and frame filter press is widely used in chemical industry, pharmaceutical industry, environmental protection, food and other fields. During the working process of the plate and frame filter press, the plate and frame sealing structure is a key component to ensure the normal operation of the equipment and the filtering effect.

[0003] The traditional plate and frame sealing structure usually adopts simple gaskets or sealing strips for sealing. However, in practical applications, this sealing method often has problems such as leakage and unstable sealing effect. Leakage will not only lead to a decrease in the filtering effect, but also may cause environmental pollution and material waste. At the same time, the unstable sealing effect will also affect the operating stability and production efficiency of the equipment. Therefore, we need to propose a plate and frame sealing structure for a plate and frame filter press. Utility Model Content
