Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a filter press which is easy to clean. Background Art

[0002] Filter press is the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, the capital equipment investment is large, and the filtering capacity is also low, it is still widely used in some small sewage treatment plants because of its advantages such as large filtering driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs.

[0003] After the frame filter press dehydrates the sludge, it solidifies into mud cakes and remains between the plates and frames. After dehydration is completed, the mud cakes need to be removed to facilitate next use. The traditional method of cleaning the mud cakes is manual cleaning, which is time-consuming, labor-intensive and inefficient. Later, machines were used to replace manual labor, and the mud cakes were separated from the separated plates and frames by mechanical knocking and vibration. Due to the different knocking strength and the adhesion of the mud cakes, some mud cakes could not fall off the plates and frames, resulting in incomplete cleaning of the mud cakes.
