Description

The diffuser 10 is mounted under the sieve in its loading part in such a way that its input sonlo is located at the junction of the sieve 2 but its entire width, and the diffuser 11 is installed under the perforated dielectric partition 5.

The confusors 12 and 13 are placed over the electrodes opposite the diffusers, and in the places where they are located, the electrodes are made perforated. The diffuser 10 may be located at a direct or acute angle to the surface of the sieve 2, and the diffuser 11 - at an acute angle to the surface of the partition 5.

The machine works in the following way.

The grain mixture from the feeder hopper 1 is fed to the charging part of the sieve 2, where under the action of the air flow, leaving it from the diffuser 10, is brought to a fluidized state. In such a mixture, all light particles and impurities are in the upper fluidized bed and, having received sieve charge 2, under the action of electric forces and partially air flow, they are attracted to the electrode 3, where they are very hot, partially. that is, they are removed from the interelectrode space in a known manner (for example, with a nomos, and an electrode surface made movable). Upon further movement under the action of vibration forces and due to the inclination of the sieve 2, the mixture leaves the zone of action of the air flow, loses its fluidized state, and its fractions in the oriented position, i.e., the long axis perpendicular to the electrode, moves to the end of the sieve. With this movement, some of the impurities pass through the sieve holes 2 and enter the tray 17.

Subsequently, the mixture enters the perforated partition 5, where it is re-brought to a fluidized state. In this state, the mixture enters the electric field created by the scrubber drum 6 and electrode 7.

Because the full grain, including rice and mustache, in the fluidized bed are in its lower part, during free fall in the interelectrode space they are not attracted to the drum 6 and enter the clean grain tray 16. The light and fine impurities remaining in the mixture are attracted to Barbai 6, from which they are removed by the scraper 15 and fed to the waste tray 18. In the fluidized state zones, some small and light impurities commensurate with the holes in the electrodes are sucked out from the mixture by confusors 12 and 13 and enters cyclone 9.

Such a machine structure, without significantly increasing its dimensions, allows to increase productivity, improve cleaning quality, reduce dustiness of air in the zone of the machine operation and eliminate corona discharge in the interelectrode space.
