Description

"

The invention relates to the field of separation of bulk materials, D particularly to a technique for separating the products of the milling and animal feed industries.

A known inertial separator includes a distributor, a rotor with vertically mounted radial guides and separating blades, a loading nozzle, receivers of selected fractions, and a rotor drive 1.

The disadvantage of a separator is its low capacity.

The closest in technical essence and the achieved result of the invention is a device comprising a working body containing a distribution device made in the form of horizontal disk rings mounted one above another, the inner diameters of which decrease from the top ring to the bottom one, a rotor with vertically mounted radial directions separating blades and separating blades, charging nozzle and receivers of coarse and fine fractions with exhaust nozzles and a drive 2.

A disadvantage of the known device is the low quality of separation.

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

The goal is achieved by the fact that the separator is equipped with an additional working body, a conical pipe installed between the receiver of a large fraction of the main working body and the loading pipe of an additional working body and labyrinth seals installed at the interfaces of the small and large fraction pipes and receivers of these main fractions and additional working bodies, each shutter being made of a felt ring disk that separates the blades, the inner diameter otorrhea equal to the outer diameter of the loading tube, and the elastic cylindrical member connecting the disc with a felt ring, and each labyrinth seal is designed as a set of three con- centric tsilindriches2093222

elements, while the inner and outer cylindrical elements are rigidly connected to the rotor.

FIG. 1 given inertial separator 5, general view; in fig. 2 — node I in FIG. one; in fig. 3 - node II in FIG. one.

Inertial separator sstp t from loading pipe 1, the main

10 working body 2 and additional working body 3 mounted on the shaft 4, conical collection 5 intermediate products, receivers coarse 6 and fine 7 fractions with exhaust nozzles 8 and 9 of the drive with an electric motor 10 and pulleys 11 and 12 and bearing assembly 13.

Main 2 and additional 3 working bodies have the same

20 and include mounting discs 14, distributor discs 15 separating the trap. mouth 16, nozzles for the withdrawal of large 17 and small 18 fractions. The conical collection 5 of the intermediate fraction in the lower part ends with a pipe 19, which serves as a loading port for an additional working member.

3Q The closure in the main and additional working bodies has an identical device and consists of disks 20 covering the separating blades from above, felt rings 21 adjacent to the outer surface of the loading nozzles 1 and 19 and elastic (for example, rubber) cylindrical elements 22, which the lower part is connected to the disks 20, in the upper part the cylindrical elements 22 are angled by the curved profiles 23 connected to the felt rings 21.

The labyrinth seals in the main and additional working bodies are similar in design and include concentric cylindrical elements 24 and 25 rigidly connected to the rotor, and stationary cylindrical elements 26.

5 The separator operates as follows.

The original product through the loading nozzle 1 enters the disk distribution device 15

55 of the main working body 2 and further on the blade 16 with wedge-shaped calibrating channels. When particles move along the blades, they become

according to its size, the gauge channels. The fine fraction by pipe 18 is sent to receiver 7 and is then removed from the machine through exhaust pipe 9.

The intermediate fraction is discharged into the stationary conical collector 5, from where it enters the flexible pipe 19 and the disk distributor 15 of the additional tool 3. Next, the product moves along the blades 16, in which there are wedge-shaped calibrating channels, which begin from the axis of rotation on this the same distance,, as in the main working body 2, which creates the same conditions for the separation of the fine fraction through the calibrating channels both in the main and in the additional working body.

The coarse fraction descends from the blades 16 of the additional working body through the nozzles 17 and goes to the receiver 6, and the small fraction is combined with the similar product formed after separation on the main working body and enters the receiver 7.

The shaft 4, on which the main and additional working bodies are mounted, is fixed in the Bearing unit 13 and is driven into rotation from the electric motor 10 through a V-belt drive with pulleys 11 and 12.

Due to the installation of an additional working body in the inertial separator, the separation efficiency is increased, since the small fraction 5, which did not succeed in the main working body, separates when the intermediate fraction passes through the additional working body, the presence of an additional working body reduces the length of the channels and, consequently, the rotor diameter, which in turn leads to a decrease in the power consumed by the separator. 5 Reducing the length of the calibrating channels prevents an excessive increase in the speed of the product in the end part of the separating blades, which also contributes to the achievement of a high separation efficiency of 2Q.

Due to the fact that in the proposed separator, the fine fraction is collected in an external receiver and, moreover, the shutter and labyrinth seal are installed in the separator, the mutual clogging of the fractions is minimized, which also contributes to an increase in the separation efficiency.

The application of the proposed inertia30

This separator will allow to increase productivity, efficiency of fine fractions, quality of separation, to reduce the specific metal consumption and energy intensity per unit of production.
