AI Technical Summary
In existing plate and frame filter presses for polyaluminum chloride filtration, the filter residue is easily squeezed into lumps and adheres to the filter plates, making it difficult to fall off automatically and inconvenient to clean, thus affecting the next filtration use.
The filter is filtered by using a hydraulic cylinder to drive the extrusion plate. After the filter is filtered, the extrusion plate moves in the opposite direction and separates the filter plates. The filter residue is thoroughly cleaned by adjusting the spacing of the hollow discs and the up-and-down movement of the cleaning brushes in conjunction with the drive motor. The filter liquid is sprayed out by a water pump to clean the filter while brushing.
It achieves complete cleaning of filter cake and thorough cleaning of filter plates, ensuring that the next filtration is not affected, and improving the efficiency and cleanliness of the equipment.
