Filter press is a kind of equipment for solid-liquid separation, mainly used for the dehydration and filtration of solid and liquid phase materials. The working principle is that the solid liquid mixture is compressed on the filter cloth or filter plate by applying a certain external pressure, so as to achieve the separation of solid particles and liquid.

Filter press mainly includes frame, filter plate, pressure chamber, washing system, electrical control system and so on. At work, the solid-liquid mixture needs to be placed in the pressure chamber, and then pressurized by the pressing device, so that the mixture is gradually compressed on the filter cloth or filter plate, the solid particles are fixed on the filter cloth or filter plate, and the liquid is discharged through the filter cloth or filter plate micropores to achieve solid-liquid separation.

In the entire process, the filter cloth or filter plate of the filter press plays the role of the filter medium, effectively separating solid particles and liquids. At the same time, the filter press is also equipped with a water washing system, which can be used to clean the filter medium and maintain the filtration effect. The electrical control system is used to control the working process of the filter press to ensure its normal operation.

In general, the filter press applies external pressure to filter the solid-liquid mixture using a filter cloth or filter plate, and finally realizes the purpose of solid-liquid separation. It is widely used in chemical, pharmaceutical, food and other fields, and is an efficient solid-liquid separation equipment.
