[0002] Plate and frame filter press is a commonly used solid-liquid separation equipment, widely used in chemical, metallurgical, mining and other fields. The principle of filtration is to use filter media to pressure filter the material to separate the solid particles, thereby realizing the solid-liquid separation process. In terms of operation control, by controlling parameters such as pressure and liquid flow rate, the filtration process can be automated and precisely controlled to improve production efficiency and product quality.

[0003] The plate and frame filter press is a device commonly used for solid-liquid separation. It is usually composed of a filter press frame, filter plates, filter cloths and liquid discharge ports. The filter screen of the plate and frame filter press is not easy to clean when it is working. Solid particles may remain on the filter screen during the filtration process.
