Abstract

This invention relates to a technique for separating loose mixes on friction inclined decks and can be used in the agricultural, chemical, mining industries. The purpose of the invention is to reduce the energy intensity of the bulk separation process. The initial mixture is fed to the friction inclined deck 1, the material is vibrated and the fractions are removed from the sides and the end of the lower base of the deck. Vibration oscillations are reported in the plane of the cross section of deck 1 perpendicular to its longitudinal axis with a frequency equal to the natural frequency of oscillation of the particles of the mixture fraction emitted from the sides of deck 1. In the device above the upper edge of deck 1, the 4, 6, 8. On decks 1, perpendicular to its longitudinal axis, receivers 4, 6, 8 of separation products are placed, made in the form of trays inclined in the longitudinal direction. Friction deck 1 in cross section is designed as a tautochron. The oscillating part of the machine is derived from the equilibrium state when the drive 9 is turned on oscillates and oscillates in the symmetry plane of deck 1. The particles of the mixture, interacting with the vibrating decks 1, swing in their cross section at different frequencies. 2 sec. f-ly, 2 ill.

Above decks 1, there are fixed loading devices 5 with GI-Tayu.im holes 6 located above the base of the edge of the decks 1 in the middle part. The unit 1, the receivers 2-4 and the load devices 5 are rigidly interconnected and are installed on the frame 8 by means of the guides 7. The device contains a drive 9 oscillations, made, for example, in the form of a curved mechanism.

The device works as follows.

When the drive is switched on, the 9 oscillations oscillating with a part of the machine is brought out of equilibrium and oscillates in the plane of symmetry of December 1. After the steady state oscillations occur, the grain mass is fed into

The new part of the upper surfaces of Dec 1 with the help of the tool 5. To do this, open the feed openings 6 located above the middle part of the surfaces of the Decks 1 to the required amount.

When interacting with vibrating decks 1, the particles of the mixture begin to swing in the cross section of the decks. Moreover, the greatest range of oscillations due to resonance are particles whose frequency of cobers coincides with the frequency of oscillations of the deck itself. Such particles are dropped through the edges of Dec 1 into the first receivers 2 and the separation products located under the widest upper part of Dec 1. The following receivers 3 fall into particles that are close in properties to resonating ones. At the end of the receiver 4, particles that by their properties do not enter into a resonant mode of motion roll down.
