Abstract

The invention relates to the technique of separation of bulk materials and can be used in agriculture, mining, chemical industry and other sectors of the national economy. The purpose of the invention is to improve the quality of separation. The separator consists of a friction surface - deck 1, which has a double longitudinal-transverse inclination to the horizon. Deca 1 is driven by a vibration exciter. The initial mixture enters deck 1 from a feeding device (PP) 13 installed at the lower longitudinal edge of deck 14 of deck 1. Receivers 15 located along the perimeter of deck 1 are intended to collect separation products. Under PP 13 and across deck 1, sections are located across its width 16 and 17 with a smaller roughness, with the lower part 18 of section 17 located below the PP 13, and its upper part 19 is located above the projection of section 16 onto the upper longitudinal edge of deck 20 of the deck 1. Particles hitting section 16 acquire an incremental speed, and upon meeting with deck 1 brake ts. At this point, the rounded particles begin to roll and move toward the lower receivers 15 of the separation products. Flat particles start moving up through deck 1 and into the upper receivers 15 of the separation products. In the area overlapping the width of the separating surface of the zone of convergence of intermediate fractions, there is an increase in the velocity of the particles, which leads to more dramatic inhibition when the material passes from a less rough surface to a rougher surface. At the same time, particles, which are close to rounded, go into the rolling mode and move to the lower receivers 15. 5 Il.

4 - Parts The invention relates to the technique of separation of bulk materials and can be used in agriculture, mining, chemical industry and other folk industries for the separation of bulk materials into fractions.

The purpose of the invention is to improve the quality of separation.

FIG. 1 shows a separator, the view of FIG. 2 - the same, side view; the same, top view; in fig. ca, located on a plane in such a way that its motion corresponds to the motion of a flat particle; in fig. 5 shows the same particle, located on the plane in the same way that its movement corresponds to the movement of a rounded particle.

The vibration separator consists of a friction surface (deck); the 1.1-long angle of inclination to the horizon is controlled by mechanism 2, the transverse one by mechanism 3. When mowing these mechanisms, the bottom deck 1 is attached to the vibrating table 4, which is mounted on springs of an elastic suspension 5, symmetrically located on the base plate 6 of the bed 7. The vibrating table is set in oscillatory motion by the vibration exciter 8, which is mounted so that; 1 it acts through the center of the oscillating part of the separator and makes an acute angle with the direction of growth under the head of the working body. The vibration exciter is set in motion from the electric motor 9 through the V-belt drive 10, the intermediate gear 1 1 and the elastic clutch 12. The initial mixture enters the de-1 from the power supply device 13 installed at the lower longitudinal edge of deck 14 1. Receivers 15 are used to collect separation products. located around the perimeter of deck 1. Iodine boot. Fixture 13 is located section 16 with a lower roughness. In addition, across the entire width of deck 1, there is a smaller roughness section 17, the nip part 18 is located below the boot device, and the upper part 19 is located along the projection of section 16 onto the upper longitudinal edge 20 of deck 1.

The separator works as follows.

Iodine action of directed vibrations generated by the vibration exciter, the original

the material from the feeding device 13 enters its deck 1. At the same time, the particles immediately get to area 16 with a smaller roughness, acquire additional speed, and when they meet with the pairing surface they decelerate and particles close to rounded begin to roll ( fluctuations in their speed increases) and fall into the lower receivers 15 of the separation products.

0 Having decelerated the particles, they begin to move upward along the working surface and enter the upper receivers of the 15 separation products. Some of the particles that are close to rounded may not be able to acquire the necessary speed for rolling due to collisions, in which case they will fall into section 17, which is made with a lower roughness, which is at an acute angle to the longitudinal edge of the cross section when moving to the side receivers. 1. At this site, also by increasing the speed of movement of the particles and their braking, when they meet the working surface, the particles, which are close to rounded, go into the rolling mode and are mixed into the lower receivers 15.

Thus, the separator eliminates the possibility of particles close to rounded falling into the side receivers, which significantly improves the quality of separation.
