Description

The invention relates to a device for cleaning fluids from ferromagnetic impurities and can be used in the chemical, metallurgical, energy, mining and other industries.

The purpose of the invention is to improve the regeneration of the filter, reducing energy consumption and the consumption of washing liquid due to oscillations of the nozzle according to the principle of a cage rotor in an alternating electromagnetic field.

FIG. 1 schematically shows an electromagnetic filter, a general view; in fig. 2 is the same cross section.

The filter consists of a housing 1 with nozzles 2 and 3, inside of which there is a ferromagnetic filter nozzle in the form of a package of concentric rings 4 with holes 5, and outside there are sections 6 of the magnetizing coil, between which electromagnets (vibrators) 7 are connected, connected to alternating current when washing the filter and creating oscillations of the nozzle, which serves as a set of vibrators or a rolling rotor.

Electromagnetic filter works as follows.

The filtered liquid passes through the filter nozzle 4, magnetized by direct current, passing in section 6 of the coil. Filtered particles on the top10

the filter nozzle filtered particles turn on the reverse flow of wash water, sections 6 of the magnetizing rolls are disconnected from the direct current, and the electromagnetic vibrators are turned on alternating current. The filter head, which is driven by an electromagnetic vibrator or a rolling rotor, oscillates. The resulting flows of water in the nozzle holes, as well as inertial forces and cavitation phenomena, help to remove the filtered particles, increase the efficiency of filter cleaning, particles, and shorten the filter washing time. On the filter housing can be

J2 are placed Zp vibrators (n is a positive integer) with windings connected in a star or a triangle circuit and included in a three-phase sinusoidal voltage. In such a case, the filter-pad nozzle oscillates according to the principle of a rolling rotor of special asynchronous motors with a rolling rotor and the amplitude of oscillations increases with a lower power of electromagnets.

The number of vibrators, their design features and location on the filter housing, as well as the parameters of the supply voltage can be different depending on the design features of the filter, its performance, etc. The filter can be washed practically at
