Description

The utility model relates to machines intended for use in agriculture, in particular, for sorting grain.

Known dielectric separator, comprising a feeder, a system of electrodes connected in sections, alternating in sign and located on a drum, receivers of separation products (see AS USSR No. 759139, IPC ⁸ V03C 7/02, publ. 08/30/1980 )

The disadvantage of the dielectric separator is low productivity, due to the limited supply of material to the surface of the drum.

Known dielectric separator, including a drum with grooves on the inner surface and alternating polarity electrodes located in the grooves (see AS USSR No. 829190, IPC ⁸ V03C 7/02, published on 05/15/1981).

The disadvantage of this trier is the low efficiency of grain separation of various fractions and low productivity.

Closest to the claimed technical solution is a trier, including a feeder, a honeycomb cylinder, inside which there is a suction pipe with a brush, and receivers of the selected fractions (see AS USSR No. 204794, IPC ⁸ V03C 7/02, publ. 10/20/1967 g.).

The disadvantage of the prototype is the low fractionation efficiency and low productivity, because requires separate cleaning of short and long impurities.

The objective of the proposed technical solution is to increase the efficiency and productivity of grain separation due to the selective effect of an electric field on grains of various shapes.

The solution to the technical problem is achieved by the fact that the known dielectric trier, including feeder, mesh cylinder, inside

of which there is a suction nozzle with a brush, and the receivers of the selected fractions, according to a utility model, are additionally equipped with electrodes located on the outer surface of the mesh cylinder, alternating in sign and connected in sections, and the suction nozzle is made two-section, with a hole made in each cylinder cell, and the electrodes are installed with a gap across the opening of the cylinder cell.

This design will improve the productivity and efficiency of grain separation of various shapes.

The essence of the utility model is illustrated by drawings, in which Fig. 1 shows a cross section of a dielectric triera, in Fig. 2 a section along A-A in Fig. 1, in Fig. 3, a sectional cell with a hole and electrodes, in Fig. 4, an electrical diagram of a dielectric triera.

The dielectric trier consists of a feeder 1, a mesh cylinder 2 with electrodes located on it 3. Inside the mesh cylinder 2, a two-section suction nozzle 4 is installed. The cylinder 2 is formed by cells 5. To release the cells 5 from long particles, a brush 6 is installed on the outer wall of the suction nozzle 4. At the end of the cylinder 2, a receiver 7 is installed for collecting long fractions. The mesh cylinder 2 is mounted on the shaft 8 and rests on the rollers 9.

In the cells 5, a hole 10 is made across, which electrodes 3 of different polarity are installed with a gap.

The electrodes 3 are connected in sections 11, 12, 13 and 14, powered through the collector 15 from the voltage divider 16 without breaking the electric circuit.

Dielectric trier works as follows.

The source material is fed onto the inner surface of the mesh cylinder 2 with electrodes 3 into the zone of section 11 with a maximum electric field strength. Under the action of the forces of the electric field created by the electrodes of 3 alternating polarity, the oatmeal, cockle and grain fall into cells 5. The full grain completely falls into

cells 5, are oriented along the lines of force of the electrostatic field, overlapping the electrodes 3, are attracted to them and move together with the cylinder 2 to the nozzle 4. When the cylinder 2 rotates, sections 11, 12, 13, 14 are switched over and the tension decreases along the separation zone, which allows you to divide the material into several fractions. Puppet, due to the gap between the electrodes 3, rising to a certain angle, rolls into the zone of section I of pipe 4. Oatmeal longer than full grain is knocked out of cell 5 by brush 6 and, moving to the exit at a certain angle to the generatrix of cylinder 2, reaches receiver 7 and is deleted. Full grain, reaching the zone of section II of pipe 4, is extracted from cell 5 under the influence of air flow and sent for further processing.

Using the proposed dielectric triera will allow, in comparison with the prototype, to increase the productivity and efficiency of separation of grain of various shapes.
