Description

one

The invention relates to mineral processing equipment, in particular, to the construction of an air-through type separator, and can be used to separate a mixture consisting of electrically conductive and non-electrically conductive materials, for example, in the case of these secondary non-ferrous metallurgy.

A pneumatic separator is known, which contains a vertical zigzag separating chamber consisting of a pipe and an upstream channel, loading and unloading pipes 1.

The disadvantage of this separator is its unsuitability for the separation of fine electrically conductive particles.

Also known pneumatic separator containing a zigzag with the same width in height of the working channel, loading and unloading means 2.

The disadvantage of such a pneumatic separator is its unsuitability for separating fine particles.

The purpose of the invention is to increase the efficiency of the process by allowing the separation of electrically conductive particles from the material flow.

This is achieved by the fact that the pneumatic separator is equipped with a running floor inductor mounted on the walls of the sections.

FIG. 1 shows a pneumatic separator, a general view; in fig. 2 shows section A-A in FIG. one.

The pneumatic separator consists of a multisection zigzag separating chamber 1, charging means 2, fan 3, receiver 4, inductors 5, discharge pipe 6 and discharge mechanism 7.

The sections of the separation chamber are made of a non-magnetic material, for example stainless steel, aluminum, copper, with parallel opposite walls 8. Above the walls 8 located downwards there are inductors that form channels with the same section of the section. The boot tool is made in the form of a hopper 9, a blade or other feeder 10 and the nozzle 11 connected in series with each other and one of the secant chambers.

The chamber with its lower end is connected to the receiver, in the lower part of which the unloading mechanism of the blade is installed

(rotary) type. The receiver in the side wall is connected to the fan. The inductors consist of three-phase windings 12 and magnetic cores 13. The upper discharge port 6, designed to unload the light non-conducting fraction, is curved and connected to the upper end of the separation chamber 1. The sections of the chamber 1 are detachable, connected to one another.

The proposed pneumocell works as follows.

The fan 3 is turned on. A pulverized material consisting of electrically conducting and non-conducting particles is fed into the bunker 9. The drive of the feeder 10 is turned on. At the same time, the material being separated out through the pipe 11 enters the channel of the zigzag separating chamber 1. Simultaneously with the supply of material into the chamber 1, the windings 12 of the inductors 5 are turned on. surface inductors. This is done by blowing out light, non-field-held, non-conductive particles. They are discharged through the upper nozzle 6, and the electrically conductive fraction is deflected downwards and unloaded through the unloading mechanism 7.

The proposed separator provides a good separation of fine materials containing electrically conductive and non-conductive particles, for example, when separating fine waste from sharpening carbide tools.
