Detailed explanation of the usage method and characteristics of the fully automatic microporous filter machine
Date: 2025-08-08Read: 4
The fully automatic microporous filter is a device used for efficient filtration and separation of fluids through microporous filtration media. It has automated operation functions and can continuously or batch process large amounts of liquid or gas samples. Below, the editor will introduce the fully automatic microporous filter from various aspects:
1Product Description of Fully Automatic Micro porous Filter Machine
Made by high-temperature sintering with a scientific formula, the filter element has the same aperture inside and outside, making it easy to recoil and remove slag. When the filter layer is thick and the working pressure is high, solid particles are difficult to pass through. It is a new type of precision filter machine used for precision filtration of liquids with very low solid content. This filter adopts a fully enclosed filtration method, and the filter mainly uses PA and PE pipe microporous filter elements (PA and PE pipe filter elements are made of polymer materials fired, belonging to three-dimensional filtration, non-toxic, odorless, and free of foreign objects flowing out, resistant to chemical corrosion, widely applicable, and not easily damaged. The highest operating temperature of PA pipe is 120 ° C, and the highest operating temperature of PE pipe is 80 ° C) as the filter medium. The filter housing is a vertical cylindrical shape, and the material can be selected from stainless steel 304, 316L or carbon steel lined PP, PO, PTFE, enamel glass, etc. Our company mainly produces stainless steel material. The filter has three backwash functions, namely liquid, compressed air (or nitrogen), and gas-liquid mixed backwash. It can also achieve dry slag discharge from the filter residue. The entire filter can be fully automated or semi automated according to the requirements of the demand.
2. Usage of fully automatic microporous filter machine
The microporous filter uses ultra-high molecular weight polyethylene as the main raw material, and the material meets GMP and FDA requirements. Without the use of adhesives, it has broad chemical compatibility. Before use, distilled water should be used for circulating filtration (cleaning equipment and pipelines, and checking for leaks in equipment pipelines and valves). At the beginning of filtration, the filtration pressure difference should be controlled not to exceed 0.01Mpa (by adjusting the reflux valve). After about 10 to 30 minutes, the pressure difference increases to 0.05Mpa. If the flow rate can be maintained at 0.5-1m3/h at this time. The pressure difference does not need to increase. If the flow rate decreases, the pressure difference can gradually increase to 0.1Mpa.

1. High efficiency in draining filter cake: The use of compressed gas rapid blowback method can easily and conveniently remove the filter cake attached to the outer surface of the microporous tube quickly, effectively, and safely.
2. Chemical corrosion resistance performance: Micro porous tubes are resistant to various acids, alkalis, salts, and most organic solvents. They are non-toxic, odorless, and free of foreign matter dissolution, making them highly suitable for applications in industries such as medicine, food, chemical engineering, and environmental protection.
3. High regeneration efficiency: The use of a simple gas-liquid rapid backwash and blowback method can efficiently and quickly regenerate clogged microporous tubes. After a period of use, chemical methods can be used to regenerate the filter tubes, extending their service life.
4. High filtration efficiency: for liquid-solid filtration, the smallest can filter particles of about 0.45um, and for gas-solid filtration, the smallest can filter particles of about 0.3um; The filtration rate is 99.9%, and the filtration pressure difference is low.
