The invention relates to a technique for the separation of bulk materials and, in particular, can be used in agriculture for the separation of seeds.

A known electroseparator includes a feeder, receivers for separation products, cylinders with a working surface in the form of alternating sections of conductive and dielectric materials (tl)

The disadvantages of such a separator are low productivity and sharpness of separation.

The closest in technical essence and the achieved result to the invention is an electric separator with a rotating electric field, including a feeder, working bodies in the form of rotation bodies, made of a dielectric with alternating polarity electrodes placed on their surface and installed with the possibility of synchronous rotation, and product receivers division 2

A disadvantage of the known device is the low efficiency of the separation process.

The purpose of the invention is to increase the efficiency of the separation process by increasing the area of force applied by the electric field to the particles of the material being separated.

This goal is achieved by the fact that in an electric separator with a rotating electric field including a feeder, working bodies in the form of rotation bodies made of a dielectric with electrodes of alternating polarity placed on their surface and installed with the possibility of synchronous rotation, and receivers of separation products, electrodes are placed on facing each other end surfaces of the bodies of revolution in the radial direction, and the bodies

rotations are in the form of discs mounted coaxially on one shaft.

In addition, in order to ensure that neither the ability to regulate the intensity of the field in the separation zone, one of the disks can be mounted with the possibility of axial movement.

The figure shows the proposed electric separator with a rotating electric field.

The electric separator includes two dielectric disks 1 and 2 with alternating polarity electrodes 3, mounted on shaft 4, on which keyways grooves 5 are located, and on the disks are keys 6, thereby the disks can move along the shaft and be fixed with the help of a nut and lock nuts 7, a corona electrode, a electrode 8 for charging the separated particles, a feeder 9, and receivers 10 for separation products.

The electric separator works as follows.

When a constant high voltage is applied to the electrodes 3 of the discs 1 and 2 and the shaft 4 is rotated, a rotating electric field is formed between the discs. The intensity of the rotating electric field rises smoothly to the center of the discs. The sortable material from the feeder 9, charged from the corona electrode 8, falls into the zone. Particles, carried away by the rotating electric field, depending on the electrophysical properties - the weights and masses fall into different receiver cells 10. The trajectory of the separated particles is determined by the force of gravity, electric field strength, centrifugal force. An electric separator with a rotating electric field has the advantage that it has a simple design, the zone of forceful action of the rotating electric field on the separated materials is larger and more

the similarity of the electric field, which can be axially displaced increases the sharpness of the separation with- it creates the possibility of regulating us, In addition, the installation of one of the field separation in the separation zone.
