Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a plate and frame filter press. Background Art

[0002] The plate and frame filter is a stainless steel multi-layer plate and frame filter press. It is suitable for closed filtration of liquids with a concentration of less than 50%, low viscosity, and low residue content to achieve purification, sterilization, clarification, and other fine filtration and semi-fine filtration requirements. It directly uses microporous filter membranes and can achieve the purpose of aseptic filtration without filtering through microporous membrane filters. It has a large filtration area, large flow rate, and a wide range of applications. Therefore, it is widely used in the pharmaceutical, chemical, and food industries. It is used in the filtration of injection liquids in pharmaceutical factories with excellent results. After the calcium carbide mud is squeezed by the plate and frame filter press, the resulting clear water is discharged into the water pool, and the filtered mud forms large mud cakes on the filter plates. When unloading the mud, the mud cakes will directly fall into the lower hopper of the plate and frame filter press. A grid is set at the bottom of the lower hopper to cut the large mud cakes into small pieces, which then fall onto the conveyor belt (2) and are transported away.

[0003] However, after the plate and frame filter press has been running for a long time, the mud cake will have a greater impact on the belt conveyor, which may easily cause damage to the belt conveyor. Utility Model Content
