Description

Technical Field

[0001] The utility model relates to the technical field of belt filters, in particular to an automatic cloth cleaning mechanism for a belt filter. Background Art

[0002] The dehydration process of belt filter press can be divided into four important stages: pretreatment, gravity dehydration, wedge zone pre-pressure dehydration and pressing dehydration. The technology uses new equipment filters such as program-controlled automatic chamber filter presses, diaphragm filter presses, deep sludge dehydration filter presses, integrated sewage sludge treatment equipment, online precision filtration systems and other reasonably priced, reliable and environmentally friendly filtration products.

[0003] After dehydration, the sludge needs to be transported uniformly through a conveyor belt to facilitate subsequent collection and processing. After the conveyor belt has transported the filter material, a small amount of filter material will remain on the surface of the conveyor belt. On the one hand, it will affect the cleanliness of the surface and the service life of the conveyor belt. On the other hand, it is inconvenient to clean. If water flushing is used, the flushing water needs to be purified again, which is more cumbersome.
