[0002] When traditional filtration technology processes large amounts of suspensions, it often takes a long time to achieve satisfactory solid-liquid separation effects, and the filter cake has a high water content, which increases the cost of subsequent processing. The filter press diaphragm filter plate significantly reduces the water content of the filter cake through secondary extrusion, thereby improving filtration efficiency and economic benefits. The background of the filter press diaphragm filter plate stems from the urgent need for high-efficiency, energy-saving, and environmentally friendly solid-liquid separation technology in industrial production. In many industrial fields, such as chemical, pharmaceutical, food processing, mining, environmental protection and other industries, solid-liquid separation is a basic and critical process. With the advancement of science and technology and the enhancement of environmental awareness, traditional filtration technology has gradually exposed problems such as low efficiency, high energy consumption, high filter cake moisture content, and environmental pollution.
