Description

Technical Field

[0001] This utility model relates to the technical field of filter cloth cleaning equipment, and in particular to a filter cloth cleaning device and a filter press system. Background Technology

[0002] Diaphragm plate and frame filter presses are widely used in current sludge treatment processes. However, as the equipment operates for longer periods, mud and crystalline salts accumulate in the pores of the filter cloth, necessitating regular cleaning to maintain its filtration efficiency.

[0003] Existing automatic filter cloth cleaning devices typically consist of a U-shaped frame and cleaning pipes mounted on it. This device needs to move along the length of the filter press to clean each filter cloth individually. However, in actual operation, the cleaning pipes easily interfere with the diaphragm plate and frame filter press during movement, forcing the cleaning pipes to move above the filter plates and above the sludge chamber. This displacement prevents the press water in the diaphragm plate and frame filter press from being completely drained, resulting in uneven sludge volume in each chamber during the next batch of sludge filling and increasing the filling pressure. Furthermore, long-term water accumulation in the membrane chamber, during the sludge unloading process when the filter plate assembly is opened, causes the press water to accumulate at the bottom of the membrane chamber under gravity. Prolonged gravity action of this water can lead to cracks between the membrane and the substrate, damaging the filter plate and membrane chamber. Utility Model Content
