The Structure And Working Principle Of Bag Filter

The bag filter is a pressure filter device, which mainly consists of a filter cylinder, a filter cylinder cover and a quick-opening mechanism, a stainless steel filter bag reinforcement mesh and other main components. The filtrate flows into the filter bag from the side inlet pipe of the filter shell. The filter bag itself is installed in a reinforced mesh basket. The liquid penetrates through the filter bag of the required fineness level to obtain qualified filtrate, and the impurity particles are intercepted by the filter bag. It is very convenient to replace the filter bag of this machine, and there is basically no material consumption for filtration.
Bag filters have many advantages such as reasonable structure, good sealing, strong circulation ability, and easy operation. In particular, the probability of side leakage of the filter bag is small, the filtration accuracy can be accurately guaranteed, and the filter bag can be quickly replaced, which reduces operating costs. The inner and outer surfaces of the filter are mechanically sandblasted and polished, making them uniform and easy to clean. We know that the filtration method adopted by the bag filter is the side-in and side-out method. It can also adopt the side-in and bottom-out method. The filter liquid medium is pressed or pumped into the bag filter barrel through the pressure in the pipe. , the liquid medium to be filtered passes through electropolishing and punching to support the filtration of the filter bag supported by the filter blue, and the changed solid and liquid reach the result of filtration of the liquid medium respectively.
The structural design of the bag filter is to seal the top cover and filter cartridge with four sets of rocking hammer eye bolts, making the filter more able to withstand extremely high filtration pressure and water hammer pressure impact. The bag filter consists of three parts: filter cartridge, filter basket, and filter bag. It has a compact and simple structure; the liquid to be filtered enters through the inlet of the filter, flows into the filter bag, and after being intercepted by the filter bag, flows out from the outlet of the filter. . The inlet and outlet design of the bag filter generally adopts a side-in and bottom-out method for easy cleaning.
