Product Introduction:
topenterformulatortoise shellBag FilterThe top in design adopts a 360 degree fully sealed filter bag design, ensuring that the filtration process is almost 100% leak free and has no dead corners, accurately ensuring filtration accuracy. The reliable sealing design meets demanding filtration requirements. It has many advantages such as reasonable structure, good sealing, strong circulation capacity, and easy operation. Especially the probability of leakage on the side of the filter bag is small, which can accurately ensure the filtration accuracy and quickly replace the filter bag, reducing operating costs. The inner and outer surfaces of the bag filter are treated with mechanical matte sandblasting or mirror polishing, which is uniform and easy to clean. We can also provide bag filters with layered insulation, adjustable support legs or hooks according to customer production requirements to meet the needs of different customers. Adopting the side in top in bottom out/side out method, the filtered liquid medium is pressed or drawn into the bag filter barrel through the pressure in the pipeline. The liquid medium to be filtered is filtered through the filter bag supported by the supporting filter basket, achieving the ideal solid-liquid separation and filtering effect of the liquid medium.

Note: When selecting, the material of the filter bag should be chosen according to the different filtration temperatures. Different filtration accuracies depend on the filter bags of different accuracies. Due to the fact that the liquid medium enters the filter from the top of the filter bag, the liquid can be evenly distributed on the entire filtering surface of the filter bag, making the fluid distribution in the entire layer basically constant and consistent. The negative impact of turbulence is small, and the filtering effect is good.
The main materials and structural forms, inlet and outlet sizes, design pressure, and filtration temperature selection classification of single bag filters are as follows:
