stainless steel bag filter housing

A bag filter housing is multipurpose filtration equipment with a novel structure, small size, easy and flexible operation, energy saving, high efficiency, airtight working, and strong applicability. A bag filter is a new type of filtration system. The bag filter is supported by a metal mesh basket inside the filter bag, and the liquid flows in from the inlet and out from the outlet after filtering by the pack. The impurities are intercepted in the bag, which can be used continuously after replacing the bag.

Structure and working principle

A bag filter is a kind of pressure filtration device, mainly consisting of main components such as filter cylinder body, filter cylinder cover and quick-open mechanism, stainless steel filter bag reinforcing net, etc. The filtrate flows into the filter bag from the side entrance tube of the filter shell, and the filter bag itself is installed in the reinforcing net basket, the liquid penetrates through the filter bag to the required fineness level to obtain qualified filtrate, and the filter bag intercepts the impurity particles. The machine is very convenient for replacing the filter bag, and there is no material consumption for filtration.

The bag filter has many advantages, such as reasonable structure, good sealing, strong circulation ability, and easy operation. Significantly, the chance of side leakage of the filter bag is slight, which can correctly guarantee the filtration precision and change the filter bag quickly, which decreases the operation cost. The inner and outer surface of the filter is solved by mechanical sandblasting and polishing, which is average and easy to clean. We know that the filtration method taken by the bag filter is the method of side in and side out, and the technique of side in and bottom out can be taken. Through the pressure in the pipeline, the filtered liquid medium is pressed into or pumped into the barrel of the bag filter. The liquid medium to be filtered is filtered through the filtering bag of the electric polishing punching support filtering blue support. The solid-liquid change occurs to reach the result of the liquid medium being filtered respectively.

The structure design of the bag filter is designed by four sets of rocking hammer ring head bolts to seal and lock the top cover and the filter barrel so that the filter can better withstand the high filtration pressure and water hammer type pressure impact. A bag filter consists of three parts: filter cartridge, 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 through the outlet of the filter after being intercepted by the filter bag. The bag filter's import and export design generally adopts the side inlet and bottom outlet method, which is convenient for cleaning.

Main advantages

1）Small chance of side leakage of the filter bag, which firmly ensures the filtration quality.

2）Bag filters can carry significant working pressure, slight pressure loss, low operating cost, and apparent energy-saving effect.

3）The filtration precision of the filter bag has been improving and has reached 0.5μm.

4）Bag filtration has a large processing capacity, small volume, and large dirt holding power.

5）Based on the working principle and structure of the bag filter system, it is convenient and quick to replace the filter bag, and the filter is free of cleaning, saving labor and time.

(6) Filter bags can be used repeatedly after cleaning, saving costs.

7）Bag filter has a wide range of applications, flexible use, and various installation methods.
