Description

The invention relates to electrical separation devices for the separation of bulk materials and can be used in agriculture for the production of seed mixtures.

 The purpose of the invention is to increase the efficiency of the seed separation process,

Fig, 1 shows a dielectric calibration-sorting device, side view; Fig, 2 - the working body section.

The dielectric gauge-sorting device contains a hopper 1, a working body 2 located beneath it, made in the form of an endless electrically conductive cloth mounted from electrodes in the form of transverse metal bars 3 of triangular shape and transverse metal bars 4 of triangular shape with an electrically insulating coating connected between connected to one of the terminals of a high voltage source (not shown), driven by a drum 5, filled with an electrical insulating base with a m of a conductive material deposited on its surface and connected to the second terminal of a high voltage source, a driving drum 6 made of a dielectric material, on the perimeter of which plates 7 of elastic elastic insulating material are fixed with a width of metallic base bar with electrical insulation coating

tiem, receivers 8 for separation products by weight and receiver 9 for small seeds, located inside the working body 2,

The device works as follows.

The seed mixture from the hopper 1 enters the surface of the working body 2 ,. made in the form of an endless web on which transverse metal rods 3 and transverse metal rods 4 are installed with an electrically insulating coating with a certain gap A ,, and divided into two fractions: small and large seeds,

Small seeds, m, e, seeds that have smaller geometries.

than the gap A, the passage through it, enters the receiver 9 small seeds. Larger seeds remaining on the surface of the working body enter the separation zone in the area of the driven drum, where due to the action of a non-uniform electric field arising between the rods . polarities are polarized and attracted to them under the influence of an electric force,

In view of the different quality i.e (

homogeneity of seeds; the magnitude of the electric force for different seeds varies. When the web is moving, the seeds are divided into different quality fractions of the separation products. The electrically insulating plates 7 mounted on the driving drum 6 serve to clean the working surface from stuck and sunflower seeds.
