Description

Technical Field

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

[0002] A vacuum filter is a device that uses vacuum negative pressure as a driving force to achieve solid-liquid separation. Under the action of vacuum negative pressure, the liquid in the suspension is sucked away through the filter medium (filter cloth), while the solid particles are retained by the medium, thereby achieving separation of liquid and solid. The rubber belt filter has the advantages of high filtration efficiency, large production capacity, good washing effect, low filter cake moisture, flexible operation, and low maintenance cost. The rubber belt filter can be widely used in solid-liquid separation in metallurgy, mining, chemical industry, papermaking, food, pharmaceuticals, environmental protection and other fields, especially in gypsum dehydration in flue gas desulfurization. However, after the existing vacuum filter is used, solid residues are easily adhered to the filter cloth surface. Most of the existing technologies use clean water spraying for cleaning. Although this method can clean some solid residues, some residues will still adhere to the filter cloth surface, blocking the filter cloth mesh and affecting the subsequent solid-liquid separation process. For this reason, we propose an automatic cleaning device for a vacuum filter. Utility Model Content
