Abstract

The invention relates to devices for cleaning working media from ferromagnetic particles and provides an increase in the efficiency of self-regeneration of the working chamber. For this, the magnetic filter is additionally equipped with a rotor (P) 3 located between the housing 1 and the magnetic system 2 and dividing the working chamber into separate sections by the ribs 4, and in the part of the body opposite to the outlet pipe from the magnetic system 2 and P 3 there is a vertical screen 5 from ferromagnetic material. The liquid to be purified enters the working chamber between the housing 1 and P 3, which begins to rotate. Ferromagnetic particles are attracted to the outer surface of P and rotate with it. The outer surface P, the passage of the screen area 5, where the screened effect of the magnetic field on the ferromagnetic particles occurs, is cleaned of dirt particles. The purified liquid is discharged through the outlet to the outside. 2 Il.

Description

FIG. 2

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

OBJECT OF THE INVENTION Increasing the self-reagent filter capacity

Fig 1 shows a filter, a prodot, a slit, Fig 2 shows a section A-A in Fig 1

The filter contains a non-magnetic body 1, a magnetic system 2 consisting of IC magnets magnets assembled in the form of a rod, a vertically positioned rotor 3 with long edges 4, vertically located between the magnetic system and the rotor in the part of the body that is opposite to one of the branch pipes material, the inlet 6 in the opposite direction - in diameter from the outlet 7 of the upper part of the housing, a bunker 8 with a magnetic holder 9 i permanent magnets 10

The longitudinal ribs 4 divide the working measure into individual sections along which the direction of fluid motion is oriented strictly along housing I and i the same time the ribs 4 are blades due to which rotational motion is reported to the rotor 3 fluid. coming into the working chamber through the inlet 6.

The device works as follows.

In the mode of cleaning the working media, the cleaning fluid with the presence of ferromagnetic particles of contaminants in it enters through the input nai of the cuttings 6 into the working chamber between the housing 1 and the rotor 3, which begins to rotate. The ferromagnetic particles entering the magnetic field are trapped by it and attract are driven to the outer surface of the rotor 3 As a result of the uniform magnetic field around the entire circumference of the rotor 3, the ferromagnetic particles held by the magnetic field rotate with the rotor 3

A shielded magnetic field effect on the ferromagnetic particles held by it on the outer side of the rotor 3 is observed in the part of the body opposite to the output part of the body where the magnetic screen 5 of ferromagnetic material is located. For each individual particle of soil held on the outer surface of the rotor 3 and rotating with the rotor there comes a moment in time when it comes to the zone of action of screen 5 As a result of the magnetic field to the border of this zone and

the absence of such in the area of the screen 5, the contamination particles are held at this boundary with the rotor 3 continuing at the same time as the rotation. The outer surface of the rotor 3, in a similar manner, the passage of the screen area 5 is cleaned from the contamination time.

With the approach of the longitudinal rib A to the boundary of the zone of action of the screen 5 held 10 that at the boundary of the zone, the soil particles are introduced into this zone and the flow of liquid

during the period of passage of the rib 4 of the whole zone, i the length of body 1 to the bunker 8 is displaced. When rbrr 4 leaves the zone of action of the screen 5, parts 1 enoena fall into G the magnetic field of magnets 2 and are attracted

to the outer side of the rotor 3, but lower vertically with respect to its former location. In the next period of time that the rib 4 passes through the zone of action of the screen 5, the particles are displaced even lower

m t d

As a result of such movements, the particle approaches the bunker 8, where it is captured by the magnetic field of the permanent magnets 10. located on the bunker 8 Cleared from

ferrous magnetized particles of contamination liquid is led through the outlet to the outside

The proposed magnetic filter will increase the cleaning efficiency.
