SU1289549A1 - Apparatus for electroseparation of seeds - Google Patents

Description

one

The invention relates to devices designed to separate seed mixtures according to electrofriction properties, and can be used to separate seed mixtures in selection work when selecting more valuable seeds.

A friction separator is known which includes a rotating disk with a friction peripheral part.

A disadvantage of this device is that it provides separation only by friction properties and does not. Gives a sufficiently high degree of separation of the seed mixture into its components.

The closest in technical essence is a device for electroseparation of seeds, which includes a working body, a system of alternating electrodes used on the working body, a feeder and receivers of separation products.

However, this device is characterized by insufficient clarity of separation of seeds.

The purpose of the invention is to increase the efficiency of the separation process by increasing the friction force by the electric field.

This is achieved by the fact that the electrodes are arranged with the formation of the Archimedes double helix, the working body is made in the form of a disk and the device is equipped with a spreading disk made of conductive material and installed between the feeder and the electrode system.

FIG. t shows the device, side view; fig 2 is the same, top view.

The seed separation device consists of a feeder 1, located above the center of rotation of the working disk 2 plane, a conductive disk 3, into which center the seeds are fed from the feeder. The working rotating disk is made in the form of Archimedes' double helix of two insulated wires. The power to the disk winding is supplied from an alternating voltage source through collector rings 4. Receivers 5 are installed around the disk circumference.

The device works as follows.

The seeds from the feeder 1 fall into the center of the disk 3 located on the disk 2 rotating with a certain speed. In zone 3, the electric field does not affect the seeds, and due to the centrifugal force, they slide along the surface of the disk to its peripheral part. After dropping from disc 3 on the seeds, electrical force begins to act. Depending on the electrical force acting on the seeds, and the coefficient of friction of the seeds on the coating of the disk 2, the sorted material comes off the disk surface along different trajectories and enters different receivers.

The use of this device provides an increase in the completeness of the separation of the mixture into its component components and can be effectively used for the mechanization of work in selection, sorting and primary; seed breeding when cleaning breeding seed samples from difficult-to-separate and quarantine seed plants.
