How Magnetic Filter Working

Magnetic filter (strainer): it is mainly used to separate fine iron filings from liquid medium to meet the process requirements of liquid medium.

Advantages of magnetic filter (strainer):

In the process of liquid slurry transportation, when the slurry passes through the filter, the iron impurities in the slurry are adsorbed on the magnetic rod sleeve, which greatly reduces the iron impurities in the slurry and ensures that the iron impurity content can be effectively controlled in the next process. Magnetic filter is widely used in pigment, dye, petrochemical, pharmaceutical, food, plastic and other industries. It can effectively remove the magnetic metal impurities in the liquid slurry transportation process, reduce the iron ion content in the product, and improve the quality of the product. The utility model has the advantages of small volume, light weight, convenient installation and operation, etc.

Working principle of magnetic filter (strainer):

When the liquid enters the filter screen through the main pipe, the solid impurity particles are blocked in the filter screen. When the medium contains fine iron filings, it will be adsorbed on the magnetic rod sleeve, and the clean fluid is discharged through the filter screen and the outlet of the filter. When cleaning is needed, the screw plug of the drain outlet at the bottom of the main pipe can be unscrewed to drain the fluid, the flange cover can be removed, the filter screen can be taken out for cleaning and then re installed. It can filter the rust, sand in the sewage and a small amount of solid particles in the liquid, so as to protect the fittings on the equipment pipeline from abrasion and blockage, and protect the normal operation of the equipment.

Features of magnetic filter (strainer):

1. Permanent magnetic bar is used, and the maximum surface magnetism can reach 10000gs and 12000gs.

2. It has the advantages of strong magnetic force, good iron removal effect and convenient cleaning of iron filings.

3. It can remove 0.5 ~ 60 μ M small particles that cannot be seen by the naked eye.

4. The surface finish of bar magnetic steel can meet the requirements of food grade.

5. Its magnetic source is made of high-performance Nd-Fe-B permanent magnetic material, and its magnetic force is 5-20 times higher than that of similar conventional magnetic materials (ferrite or alnico permanent magnetic material).
