Bag filter is a kind of multi-purpose filtering equipment, which is characterized by novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work, and strong applicability. Inside the bag filter, the filter bag is supported by a metal mesh basket. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are intercepted in the filter bag and can be used continuously after replacing the filter bag.
Structure and working principle: The bag filter is a pressure filter device, which is mainly composed of filter cylinder body, filter cylinder cover and quick opening mechanism, stainless steel filter bag reinforcement net and other main components. The filtrate is from the side entrance of the filter housing The tube flows into the filter bag, and the filter bag itself is installed in the reinforced mesh basket. The qualified filtrate can be obtained when the liquid penetrates the filter bag of the required fineness level, and the impurity particles are intercepted by the filter bag. The machine is very convenient to replace the filter bag, and the filter basically has no material consumption.
The bag filter has 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 filter accuracy can be effectively guaranteed, and the filter bag can be replaced quickly and conveniently, which reduces the operating cost. The inner and outer surfaces of the bag filter are solved by mechanical sandblasting and polishing, which is average and easy to clean. We know that the filter method adopted by the bag filter is a side-in-side-out method, or a side-in-bottom-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 by the filter bag supported by the filter basket through the electro-polishing punching hole to achieve the result of solid-liquid separation.
