[0002] A plate and frame filter press is a commonly used solid-liquid separation device, widely used in a variety of industries, including chemical, pharmaceutical, food, and environmental protection. It uses a filter medium (such as a filter cloth or filter plate) to press the material, separating the solid particles from the material. The liquid flows out through the filter medium, forming a filter cake.
