The separator includes a vertically installed material pipeline (MP) I of a non-magnetic material, on which it is rigidly

Description

; , one

The invention relates to magnetic; enrichment and can be used to separate non-magnetic bulk materials, in particular, at 5 ne (working granular or powdered plastics, from metallic inclusions.

The purpose of the invention is to increase the efficiency of the separation process for 10 times to reduce the residual magnetized particles.

The drawing shows a separator.

Cyclic electromagnetic circuit- includes a vertically installed - if 5 le1) material material I of non-magnetic, BCHJ o material, a magnetic system consisting of a magnetizing coil

2, rigidly fixed to the material-: wire, and covering the core 20

3, installed with the possibility of reciprocating motion relative to the coil 2, a collection of ferromagits 1x particles 4 with a guide (funnel 5, arranged with a 25-minute rotation under the material conduit and connected with the kinematic core CKi | 6 and levers 7

And 8 collection of non-magnetic particles (not shown) .30

I Separator works as follows ..

When the material feed mechanism is turned on, the feed coil 2 and the heart

3, overcoming the force of the spring 6, under the action of the electromagnetic field of the coil 2 moves along its axis until it stops against the material pipe. In this case, the magnetizing coil 2 together with the core 3 form an electromagnetic field of maximum magnitude, which is used to extract ferromagnetic inclusions from the free-flowing material flow, collecting and holding them on the vertical plane of the material pipeline. and closes the window in the collection of ferromagnetic particles 4, thereby opening the material line 1 for free movement of the material free from ferromagnetic inclusions.

After the material feed mechanism is disconnected, the voltage is disconnected from the magnetizing coil 2. The electromagnetic field disappears and the core 3 under the action of the spring 6 moves along the axis of the magnetizing coil 2, moving away from the material pipeline.

At the same time, through the levers 7 and 8, the guide flap 5 rotates from around the axis, opening the window in the collection of ferromagnetic inclusions 4, thereby blocking the channel of the material pipeline 1. when core 3 is removed from them, and they, under the action of their own weight, fall down on the gate valve 5 and are poured into a ferromagnet-Lx collection of particles,
