Abstract

BACKGROUND OF THE INVENTION The invention relates to a technique for separating bulk materials by size in the agricultural and animal feed industries. The goal is to increase the efficiency and productivity of separation. A sieve cylinder 2 is installed in the vertical casing 1 of the separator, inside which a shaft is located with the possibility of joint rotation. Separating surfaces (SP) 8 are located on the shaft below each other, on which notches 11 and ribs 12 are made to pass the passage fraction. Under the SP 8, pallets 9 are installed with a clearance relative to the cylinder 2, with openings communicating with the receiver 4 of the pass-through fraction. The size of the holes is made decreasing from top to bottom. Moreover, SP 8 have the shape of cones, the smaller bases of which are turned down and have holes coaxial with holes in the pallets 9. The plan cutouts 11 and the fins 12 have the shape of a logarithmic curve extending from the center to the periphery of the cone. From the loading nozzle 5, the separated material flows into the rotating conical SP 8 and is directed to the notches 11 with the fins 12. Here the passable particles are released, which enter the sump 9 and the nozzle 10 are output to the receiver 4. A part of the material flows to the cylinder 2 and finally subjected to a separation process. 2 Il.

Description

This invention relates to a technique for separating bulk materials by size and can be used in agricultural production and in the feed industry.

The purpose of the invention is to increase the efficiency and productivity of separation.

FIG. 1 shows a separator, a cut; in fig. 2 shows section A-A in FIG. one.

 The separator consists of a conical vertical casing 1, inside of which a sieve cylinder 2 with annular channels 3 is installed with rotation potential. An annular gap between the cylinder 2 and

housing 1 forms a collection of 4 pass-through product (fraction). The upper part of the housing 1 is connected to the end pipe 5 of the load of the material being processed. In the lower part of the housing 1 there is a nozzle 6 for removal of the passage product. The lower part of the sieve cylinder 2 communicates with a collection of 7 tailing fraction.

Inside the cylinder 2 there is a distribution-separating rotor coaxially with it, consisting of conical separating organs (surfaces) 8 with rhombic trays 9 of the pass-through fraction. Rhombic pallets 9 have nozzles 10,

communicating through the annular channels 3 with the collection 4 of the passage of the product.

Separating organs (surfaces) 8 are made with wedge-shaped notches 11, with guiding ribs 12 made along a logarithmic curve,

The angle of the forming cone 8 is less than up friction,

The larger base of the conical separable surfaces 8 is directed towards the nozzle 5, the smaller base is made decreasing from the upper cone to the lower one.

All conical surfaces 8 are located one above the other and are rigidly connected to each other, for example, by means of rods 13, adjusting ,. sleeves 14 and nuts 5

To output the finished product from the collector 4 to the bottom of the cylinder 2 GGR.NChTSY blades-blades 16.

On the drive shaft 17, the crepe: -P, -1 is a hard disk 18 connected to the last cone-truncated surface 8 of the collector.

The disk 19 with the holes 20 is connected to the lower part of the sieve cylinder 2.

At the bottom of the collection of 7-words. pipe 21 for withdrawal of the tailing fraction, the large fraction is removed through pipe 21 by means of paddles-blades 22 fixed rigidly on shaft 7. Smaller bases of organs P and holes J are coaxial with gears 4, filled and on pallets.

The device works by the JT as follows.

The material being processed from the nozzle 5 enters into the rotating conical separating surfaces 8, and as it progresses from top to bottom it is gradually distributed into several streams and is directed to the wedge-shaped slits 11 by the guide ribs 12, where the floor is acted upon by centrifugal and coriolistic forces. the moving particles along the slots 11 props, DI1 release of passable particles that enter the rhombic pallet 9 and the nozzle 10 are output to the collector 4 of the passing product.

A part of the processed material, which did not have time to stand out on the separating surface 8, under the action of centrifugal inertial forces enters the rotating sieve cylinder 2 and is finally subjected to the separation process. The passage particles enter the collector 4 and the blades of the mi-blades 16 through the nozzle 6 are brought out. The product that did not pass through the separating surface of cylinder 2 goes downwards to collector 7 and the blades of the paddle blades 22 are removed through pipe 21 to the outside.
