Description

sixteen

The invention relates to the technique of separating grain mixtures along the length of particles and can be used in agriculture, the milling and grain industry for cleaning seeds and food grains, as well as mining.

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

FIG. 1 shows the Trier, top view; in fig. 2 is a section A-A in FIG. one.

Trier includes a vertical shaft 1 around which working surfaces in the form of endless ribbons 3 with cells 4 located on their outer side are mounted on a cross-piece 2 for rotation in a vertical plane. Under the endless belts 3, a device is mounted coaxially to the shaft for communicating additional rotation by the belts 3 in the form of a horizontal disc 5 with an axial bore 6 for outputting a short fraction. The disk 5 is mounted rotatably along the working rotation of the belts 3 and by means of radial rods 7, attached to the shaft 1. The disk 5 peripherally abuts against the supporting rollers 8 mounted on the springs 9. The belts 3 are attached to the disk 5 through the leading 10 and driven 11 curly rollers. Leading shaped roller 10 is driven into rotational movement through the shaft 12, at the lower end of which gear 13 is installed, driven into rotation through the driving gear 14, which is mounted on the drive nozzle 15. In the lower part of the nozzle 15 there is a drive pulley 16, and in the upper part - the leading gear 17, which serves to drive the gear 18 mounted on the shafts 19, on which the receiving brushes 20 are fixed. When the water inlet 15 is mounted on the shaft using roller bearings 21. On the shaft 1 in the lower part there is a drive pulley 22.

Under the disk 5 on the shaft 1 a reflecting cone is installed - a plate 23, on the periphery of which a receiver 24 of short fractions is located. In the upper part of the shaft 1 above the belts 3 a loading device is installed in the form of a bunker 25, from which the initial mixture of grain flows through the loading sleeves 26 to the feeding platforms 27 and endless belts 3.

each endless tape 3 with a roller. 11 and the bolted connection 28 is fastened to the disk 5 through annular grooves 29 made in the disk 5, which makes it possible to make different angles o between the radius of the disk 5 and the belt 3, which makes it possible to choose the optimum modes of operation when separating various grain mixtures. On the periphery of the disk 5 is installed annular receiver 30 of the long fraction. The working surface of the ribbons 3 is made curved, facing concavity to their inner side.

Trier works as follows.

The initial grain mixture from the hopper 25 through the loading sleeves 26 enters the feeding platform 27 and hits the cellular surface of the endless belt 3. Short particles under the action of Coriolis forces and the component inertia forces fall into the cell of the ribbon 3 and move together with the ribbon 3 to the center of the disk 5 where with the help of the receiving brushes 20 they leave the tape cells 3 and through the opening 6 in the center of the disk 5 they enter the reflecting cone plate 23, which are reflected and fall into the ring receiver 24 of the short fraction. Long particles that have not fallen into the cells of the tape 3, move along its surface under the action of centrifugal forces and enter the ring receiver 30 of the long fraction.

The use of Trier will improve the quality of cleaning grain mixtures due to the intensification of filling the cells of Trier under the action of Coriolis forces and components of centrifugal forces (from a portable rotational movement) and high uniformity of cleaning cellular tape from impurities.
