Description

Technical Field

[0002] The filter press uses a special filter medium to exert a certain pressure on the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. The filter press is composed of filter plates, filter frames, filter cloths and push plates as main components for medium filtration. During filtration, the push plate pushes the filter plates, filter frames, etc. to move, squeezing the medium to separate the medium from the filtrate to complete the filtration.

Adjacent filter frames cannot be aligned during the squeezing process, which will affect the filtration effect of the medium. In addition, the existing rack structure is fixed, which is not convenient for increasing or decreasing the number of filter frames and filter plates during a single filtration according to actual processing needs.
