Description

(54) SEPARATOR FOR BULK MATERIALS

one

The invention relates to the food and large industries processing seeds of agricultural crops, and can be used in agriculture for the purification of grain used for storage and processing, as well as in the building materials industry.

A centrifugal screen is known, in which the material is fed into a screw feeder, which feeds it to the discharge ports in the rotor tube, then to the reflective ring, and under the action of centrifugal forces is thrown onto the string surface of the screen. As material progresses along the working surface, et-o is divided into two classes, which enter the discharge windows 1.

The disadvantage of this device is the implementation of the working surface of the tensioned strings, which leads to the passage of particles of litter with the grain when it is oriented along the strings, as well as a single passage of grain through the working surface.

A separator for bulk materials is also known, in which the feeder is made in the form of a rotary distribution cylinder with windows placed in the center of the disk, and the screens are vertically mounted on a rotating disk and feeder at an angle to the vertical radial planes, and partition walls 2 are installed between the screens on the disk. . -V

However, this device cannot effectively clean the seeds of seeds from coarse litter, since the device can work only at high speeds of rotation of the sifting surfaces, and the surface of the sieves is quickly clogged by pressing the sifting material to them. Cleaning the sieve requires stopping the separator. In addition, noise and vibrations during the operation of the separator impair the sanitary and hygienic conditions of servicing the device.

The purpose of the invention is to improve the quality of cleaning seeds from coarse litter, reducing the level of vibration and noise.

The goal is achieved by the fact that it is equipped with two disks

D are rotatably mounted on the outer surface of the cylinder and are kinematically connected with a drive, with the blades with a screening surface fixed between the disks and equipped with agitators, screening, and the surface is made of a volume grid, and the feeder is mounted horizontally.

Fig, 1 schematically shows the proposed device, a general view; on fi; g, 2 - section AA. in FIG. 1,

The device consists of a cylinder 1 with shaft 2 in it, on which the turns of auger 3 are fixed with a right-hand helix and coils of a 4-pin with the left direction of the helix of the loading nozzle 5, the shaft 2 is installed in bearings 6, the cylinder 1 has the name; As a rectangle, the lower side of which is located, for example, at an angle of 30 below the horizontal plane passing through the shaft 2, a gear wheel 8 is mounted on the shaft 2 to axle; the rotational gear is transmitted from the electric motor 9 by means of a gear wheel 10 and a chain gear 11. On the shaft 2 a disk 12 is fixed; rigidly connected with the planet carrier 13. Two disks 14 and 15 are mounted on the outer surface of cylinder 1, each of which is provided with three rollers 16 enabling disks 14 and 15 to rotate freely on the external surface of the hollow axis. The disk 15 is rigidly connected to the carrier 13. On the disks 14 and 15, there are, for example, eight blades 18, the length of the window does not extend beyond the blades 18, each blade consists of a voluminous (wicker) grid 19 stretched on a frame 20 having on three sides there is a limiting shoulder 21. Each lobe of the blade is equipped with a jog, which consists of a lever 22 .. having an axis of rotation 23. One end of the pfc-fjara is attached to the grid through a spring 24, working in tension. On the cylinder 1 is installed the copier 25 (In the lower part of the device there are receivers of litter 26 and grain 27,

The device works as follows.

The grain through the loading nozzle 5 enters the cylinder 1, where the turns of the shkok 3 are transported for unloading to the window 7. Due to the rotation B1-ET of the screw 4, it is pro- teed, the pressure on the moving grain contributes to the uniform growth of the grain through the window 7 and the pressing is eliminated grains. Grain from window 7 enters the screening surface of the blades 18 moving upwards. The grain passes like a HD through three rotating blades 18, and the mineral and organic litter is carried by the blades on the CTopCF5-y cylinder 1, opposite

loading on the blade. The clogged grain from window 7 enters the blade and spreads over the screening surface. In the event of a dany movement, it hits the next blade with a screening surface located at a different angle to the direction of grain movement. So Zyrno passes several sifting surfaces, making a passage through the sifting surface, passing through it, portable movement with the sifting surface and different meeting angle consistently with a number of sifting surfaces, thus achieving high-quality cleaning of grain from organic and mineral litter. After passing the blade of the maximum lift height, the short end of the lever 22 runs onto the copier 25, as a result of which the long end of the lever 22 moves away and the net 19 connected to the lever by the spring 24 does not follow. After passing by the lever, the copier abruptly returns the lever, the spring and the grid to its original position. Thus, the grid 19 is sharply shaken, which helps to remove litter stuck in the grid cells (if necessary, by installing several copiers in succession, it is possible to shake the screening surface many times). The grain enters the receiver 27, and the mineral and organic debris enters the receiver 26. The shaft 2 and the blades 18 are rotated by an electric motor through a chain transmission 11.

The use of the device makes it possible to effectively clean the seeds of large trash.
