Description

TECHNICAL FIELD

[0001] The utility model relates to filter press technical field, concretely to a filter press convenient to residual treatment. BACKGROUND

[0002] Filter press is a kind of mechanical equipment that separates solid particles from liquid in suspension by applying external pressure. The plates and frames of plate-and-frame filter press are arranged alternately, and filter cloth is covered on both sides of the filter plate. The plate and frame are pressed tightly by a pressing device, i.e. a filter chamber is formed between the plate and frame. A small hole is opened in the same position of the upper end of the plate and frame, and becomes a passage after being pressed tightly. The filtered liquid enters the filter chamber through the passage, passes through the filter cloth, and the solid matter is trapped in the filter chamber and gradually forms a filter cake. In actual use, filter cake residues remain on the filter cloth after the filter cake is removed. If not washed in time, it will reduce the working efficiency of the filter press, and it is time-consuming and laborious to clean it manually.

[0003] To this end, the Chinese utility model patent with the authorization announcement No. CN219764604U discloses a filter press convenient to clean, which comprises a filter press body.
