DZBL series high-efficiency plate-type closed filter (leaf filter/plate filter/plate-frame filter) is a new generation of high-efficiency filtration equipment designed and developed by our company based on foreign technology. This equipment is an ideal equipment for solid-liquid separation or clarification filtration in industries such as condiments, alcohol, oils, petrochemicals, chemicals, petroleum, pharmaceuticals, and beverages.

The filter components are all made of stainless steel. Since the entire filtering process is carried out in a closed container, it can perfectly replace the traditional "plastic plate and frame filter press" and can also achieve heat preservation filtering. The plate filter equipment can be customized for manual and automatic slag discharge, which is very convenient to use. It eliminates the leakage and pollution of the "open" structure of the traditional filter press, and the filtering accuracy is very high. The filtering area ranges from 2 square meters to 200 square meters for users to choose. According to the filtering process requirements, the closed container has two materials of carbon steel and stainless steel plate filters for users to choose.

Main structure and working principle of DZBL high-efficiency closed plate and frame filter/plate filter

The main body of the plate and frame filter is composed of a shell, filter mesh, a cover structure, an automatic slag discharge device, etc. Among them, the filter mesh is composed of multiple layers of stainless steel wire mesh and is installed on the central collecting pipe, which is very convenient for disassembly and cleaning.

During filtration, the filtrate containing filter aids enters the filter through a conveying system (pump or other tools), forming a stable filter cake on the filter mesh (the filter cake layer can provide countless tiny channels), and then the filtrate is actually filtered through the micropores of the filter cake layer.
