Bag filter is a pressure filtration device, which is mainly composed of filter cartridge, filter cartridge cover, quick-opening mechanism, stainless steel filter bag reinforcing mesh and other main components. The filtrate flows into the filter bag from the side inlet pipe of the filter housing. The filter bag itself is installed in the reinforced mesh basket, and the liquid passes through the filter bag of the required fineness level to get qualified filtrate, and the impurity particles are retained by the filter bag. It is very convenient to replace the filter bag, and there is basically no material consumption during filtration.

Bag filter has the advantages of reasonable structure, good sealing, strong overflow capacity, easy operation and so on. In particular, the probability of side leakage of the filter bag is small, which can accurately ensure the filtration precision, and the filter bag can be quickly replaced, reducing the operating cost. The internal and external surfaces of the filter are mechanically sandblasted and polished, which are uniform and easy to clean. As we know, the bag filter adopts the filtration method of side-in-side-out method or side-in-bottom-out method, and the filtered liquid medium is pressed or pumped into the bag filter. The barrel passes through the pressure in the pipeline. The liquid medium to be filtered is filtered through electro-polished punched holes through the filter bag supported by the filter blue, and the changed solids and liquids reach the liquid medium and are filtered respectively.

The structural design of the bag filter is to use four sets of pendulum eyebolts to seal and lock the top cover and the cartridge, so that the filter can better withstand the extremely high filtration pressure and water hammer pressure impact. The bag filter consists of a filter cartridge, a filter basket and a filter bag. The structure is compact and simple; the liquid to be filtered enters from the inlet of the filter, flows into the filter bag, and flows out from the outlet of the filter after being intercepted by the filter bag. . The inlet and outlet design of the bag filter generally adopts the side inlet and bottom outlet method, which is convenient for cleaning.

The structural design of the bag filter is made of four sets of rocker type ring head bolts to seal and lock the top cover and the filter cartridge, so that the filter is more able to withstand ji high filtration pressure and water hammer pressure impact. Bag filter consists of three parts, namely, filter cylinder, filter basket and filter bag, with a compact and simple structure; the liquid to be filtered enters through the inlet of the filter, flows into the filter bag, and flows out from the outlet of the filter after being intercepted by the filter bag. The import and export design of bag filter generally adopts the side inlet and bottom outlet mode, which is convenient for cleaning.
