Abstract

The invention relates to the process of cleaning the working media of ferromagnetic particles and provides for an increase in the efficiency of self-regeneration of the working chamber (RK) and removal of soil particles into the bunker. For this purpose, the fluid being cleaned through the pipe 7 enters the RK between the walls of the inner cylinder 2 and the outer cylinder 3 of the housing 1. Under the influence of permanent magnets 6 located on the rotor 5, the particles are trapped by the magnetic field and are attracted to the walls of the outer cylinder. Due to the rotation of the rotor 5, the contaminant particles move towards the longitudinal guide ribs (HP) 4. With the aid of magnets 6, the contaminant particles move along the HP 4 towards the bunker. The purified liquid is discharged through the outlet 8. 2 Il.

Description

The invention relates to devices for cleaning working media from ferromagnetic particles.

The purpose of the invention is to increase the efficiency of the self-regeneration of the working chamber and to ensure the discharge of soil particles into the bunker.

Fig, 1 shows a magnetic separator, a longitudinal section; FIG. 2 is a section A-A in FIG. 1,

The separator contains a non-magnetic body 1, consisting of coaxial cylinders — internal 2 and external 3; longitudinal guide ribs 4, located in the working chamber between the cylinders, vertically arranged rotor 5 with permanent magnets 6 mounted on a helical line, inlet 7, located in the upper part of the body, outlet inlet 8 in the lower part in front of the bunker 9, magnet holder 1 and permanent magnets 11, located on the bunker,

The longitudinal ribs are guides for the movement of soil particles trapped by the magnetic field of the permanent magnets located on the rotor, in the direction of the bunker under the action of the moving magnetic field as a result of alternate interception, downstream of the rotor helix by the magnets,

in the region between each adjacent longitudinal edges.

The device works as follows.

In the mode of cleaning the working medium, the rotor is 5 seconds fixed on it.

These magnets 6 are driven by a drive (not shown) to rotate. The cleaning-liquid with the ferromat particles present in it is sent through the inlet 7 to the working chamber between the inner 2 and outer 3 cylinders of the housing 1, Ferromagnet

Particles entering the magnetic field located on the rotor 5 of the permanent magnets 6 are captured by this field and attracted to the wall of the inner cylinder 2. As a result of the rotation of the rotor 5 with permanent magnets 6 fixed on it, the ferromagnetic particles move to the longitudinal guide edges 4, For each individual particle of contamination near the edge 4 there is a moment in time when the action of the magnetic field below the permanent magnets 6 located on the rotor helix L of the magnetic field 6 begins to exceed the action of the magnetic field in Spherical magnets due to their care of the rib 4. As a result, the ferromagnetic particle constantly moves along the rib 4 to the bunker 9, where it is trapped by the magnetic field of the permanent magnets 10 located on the bunker 9. The liquid cleared of ferromagnetic particles is discharged through the pigment 8 outward.

The magnetic separator allows to increase the cleaning efficiency of working media and to ensure the removal of soil particles into the bunker, preventing them from entering the repeated cleaning cycle.
