Description

The invention relates to the enrichment of minerals, namely, the designs of electrical separators for the separation of bulk mixtures, and can be used in the mining industry, in the building materials industry, in the processing of industrial waste, in the purification of powders and in other deposits.

The purpose of the invention is to increase the selectivity and productivity of separation.

Figures 1-4 schematically show the proposed separator, embodiments,

The electric separator includes a housing 1, a feeder 2 located; beneath it is a tubular collecting electrode 3, inside which a high-voltage corona electrode 4, receivers 5, 6 of separation products and a high voltage source 7, are placed coaxially. Precipitation electrode 3 is made of at least two tubes.

The separator works as follows.

Particles of the material being separated from the feeder 2 are fed into the central part of the collecting electrode 3, into the working area between the high voltage electrode A and the collecting electrode Cc. The electrode 4, made in the form of 2Q thin wires and connected to the source 7, creates inside the collecting electrode 3 a zone with ionized gas. ionized gas (corona-discharge current) charges the components of the separated material of non-conductors and conductors. Under the action of an electric field force when a pipe 8 is dropped into the separated material The series deviates to the tube 8 and is evenly distributed along the forming precipitating electrode 3 "Non-conducting particles fall along a trajectory close to the vertical, and flying through the tube 9, enter the receiver 60 35 Conducting particles, reaching the gap 10, slip through it and enter the receiver 6c. Thus, the separation of non-conductors from conductors 40 is carried out.

The movement of the conductive particles through the gap 10 is facilitated by a number of circumstances. First, the conductive particles after touching the electrode 3 restart 45

Third, the conductive particles, like the ionized plasma ha, tend to leave the zone with a high concentration of ionized particles into the zone with a low concentration of these particles.
