Description

one

The invention relates to the field of mineral processing, and HC names to devices for the separation of materials into fractions in coarse media.

A device for gravitational enrichment of mineral raw materials in heavy moving media is known, including vibrating grooves, a device for feeding material l.

The stratification of the source material into the light and th fractions in such a device occurs along the entire length of the apparatus’s bath. In this case, the liquid phase of the suspension is squeezed into the upper layers of the flow due to the vibration action, and the lower layer is compacted.

The disadvantage of the vibroseparator is the low speed of transportation of the heavy fraction, as well as the low efficiency of the separation process.

Also known vibroseparator containing the feed hopper, vibrating chute, on the bottom of which are installed water distribution pipes with openings mn 2.

However, such a vibratory separator does not provide effective material separation due to the fact that in a raegruch;

between layers of light and heavy fractions.

The aim of the invention is to increase the efficiency of material separation.

This is achieved by the fact that, in the proposed vibroseparator, the bottom of the chute is made in the separation zone cascade, and E in the transport zone from elastic material.

FIG. Figure 1 shows the proposed anti-rim vibroseparator, the cut on FC | G. 2 is a diagram of fastening the elements Ki3 of an elastic material.

Vibroseparator is made in the form of an open trough 1, connected with a moving frame 2 by inclined guide elements 3 and springs 4. Poh. The sliding frame 2 is connected by means of a screw mechanism 5 for adjusting the angle of inclination of the chute 1 to a fixed ramp 6 mounted on elastic elements 7. The electric motor 8 is connected by means of a V-belt transmission with an eccentric drive 9. The design of the working chute 1 includes a screw mechanism 10 for adjusting the height of the drain threshold . Vibroseparator in the zone of separation has a cascade of dnde 11, and in the transport zone - elastic bottom 12,

Vibroseparator works as follows.

Expose1 ": I enrich the material along with the suppression is fed into the apparatus through a loading device having a gate. After switching on the electric motor 8, the chute 1 under the action of the eccentric drive 9 performs a reciprocating motion of an elliptical character.

In the vibroseparator, under the action of the vertical component of elliptical oscillations, the suspension particles are in a vibro-fluid state, forming a bed that is sufficiently permeable for heavy inclusions of the source material, which, falling on the cascade bottom 11 of the separation zone, are vibrated into the transport zone. to form a heavy fraction.

Light inclusions, not having overcome the bed opposition, under the action of the main flow of the suspension belong to the overflow threshold and are discharged through it.
