Problems solved by technology

[0003] At present, magnetic filters mainly use permanent magnets as filter elements to remove ferromagnetic particles in the medium. However, due to the uneven distribution of the magnetic field of permanent magnets, the filtration efficiency is not high, and it is difficult to meet certain precision requirements. In addition, magnetic filtration In the process of backwashing, water is mainly used as the backwashing medium, the backwashing efficiency is low, and the water consumption is large

Abstract

The invention relates to an electromagnetic filter which comprises a filter with a liquid inlet and a liquid outlet; a magnetic conductive grid is arranged in the cylinder body of the filter; an electromagnetic coil casing is sleeved outside the cylinder body of the filter; and an electromagnetic coil is mounted in the electromagnetic coil casing, and surrounds the periphery of the magnetic conductive grid. In the invention, the magnetic conductive grid is taken as a filter element, a gradient magnetic filed is formed inside the magnetic conductive grid under the action of the electromagnetic coil, an electromagnet is formed, the magnetic filed intensity is high, the magnetic force distribution is uniform, the adsorbability of the filter element is strong, and the filtering efficiency is high.

Description

technical field [0001] The invention relates to a magnetic filter, in particular to an electromagnetic filter. Background technique [0002] Magnetic filters are mainly used in petroleum, chemical industry, metallurgy, medicine, machinery, automobile and other fields to remove a large amount of iron filings, iron powder and other ferromagnetic impurities contained in various liquids, slurries and gases, and can be used for precious metal catalysts Recycling and clarification of weak magnetic medium, etc. [0003] At present, magnetic filters mainly use permanent magnets as filter elements to remove ferromagnetic particles in the medium. However, due to the uneven distribution of the magnetic field of permanent magnets, the filtration efficiency is not high, and it is difficult to meet certain precision requirements. In addition, magnetic filtration In the process of backwashing, water is mainly used as the backwashing medium, and the backwashing efficiency is low and the wa...
