SUMMARY OF THE INVENTION: In a vibration centrifugal separator, two cylindrical sieves 10, rotating around a vertical axis and oscillating towards each other, give additional oscillations in the radial plane, for which the separator is equipped with a connecting rod, in the middle part hinged to the exciter 13 and articulated two shoulders levers 7, pivotally mounted on the rotor 4, while the sieves are connected with two shoulders levers hinges, and with the rims of the drums - flexible sleeves 11.2 Il.

Description

The invention relates to the sorting of solid materials by size, in particular to the sorting of seeds of agricultural crops, and can be used in agriculture, in the milling and other public households.

The purpose of the invention is to increase the productivity and quality of the separation process by imparting additional radial oscillations to the sieves.

FIG. 1 shows a vibration centrifugal separator; in fig. 2 - sieves connected to the rims of the drums and the vibration exciter.

The vibratory centrifugal separator includes a casing 1 mounted on frame 2, in the upper part of which a conical spreader 3 is installed, and in the middle and lower parts there is a rotor 4 on which the disc spreader 5 is located. On the rotor 4 by means of hinges 6 are articulated the links 7 of radial oscillations, which have the form of two shoulders, and with the help of hinges 6 fixed sieve drums, consisting of rims 9, cylindrical sieves 10, flexible sleeves 11 and tightening rods 12. The sieve 10 is connected to the levers 7 with oschyu hinges (conditionally not labeled). In the lower part of the rotor 4, there is an exciter 13, which is connected to the sieve drums by connecting rods 14 and 15, and with two shoulders levers 7 by an additional connecting rod 16. In the right part of the casing there is a cleaner 17, inside the frame 2, pulleys 18.19 and 20 rotor drives, vibration exciter and cleaner. From the outer part of the sieve drums, discharge scrapers 21 of lead-through particles are installed, and in the lower part of the rotor, discharge scrapers 22 for tailing particles. On the outside of the casing 1 are

trays 23 for passage-through particles and trays 24 for tail-off particles.

Vibration centrifugal separator works as follows. The grain material enters the conical spreader 3, where it receives the initial velocity, then it hits the disc spreader 5. When it comes off, the circumferential velocity of the particles is finally compared to the peripheral speed of the sieve 10 and the grain mixture lies on the inner surface of the latter. After being driven by longitudinal vibrations, the grain mixture begins to separate into large and small particles. But under the action of additional oscillations in the radial plane, this process proceeds much faster, since loosening of the grain mixture is provided. Therefore, when the sieve oscillates not only in the vertical plane, but also in the radial plane, particles are rapidly moving to the sieve surface. Once on the surface of the cylindrical sieve 10, oscillating in the vertical plane and having additional oscillations in the radial plane, the particles have an increased mobility. Additional radial oscillations reduce the intra-layer pressure and ensure the passage of small particles into the hole, thus achieving an increase in the productivity and quality of the separation process. After passing through the openings of the sieve 10, the passage particles are removed by the scrapers 21 for the passage fraction in the trays 23, and the waste particles are removed by the scrapers 22 in the trays 24.

Thus, the implementation of a vibratory centrifugal separator equipped with a connecting rod in the middle part of the articulated with an exciter and articulated movably with two shoulders with hinges and with the rims of the drums with flexible levers allows the separator to work with additional radial oscillations for cylindrical sieves , which increases the intensity of the processes of segregation of particles, and thus increases the productivity and quality of the separation process.
