Description

12388

This invention relates to separation.

granular material, in particular technological chips, and can be used. It is used in all areas of the national household ..

The purpose of the invention is to improve the quality of the separation of process chips by pre-sorting the material to be separated before it enters the main separation zone.

The drawing shows a schematic diagram of the air separator.

The device contains an out-of-the-ear vertical tubular chamber I, which is installed with the possibility of rotation by a drive 2, the lower end of the outer vertical pipe connected to the annular hopper 3. Inside the outer vertical tubular chamber 1 is a coaxial 20

An internally installed vertical tubular chamber D. is installed, with a confusor 5, Bunker 3 is equipped with a tangentially installed supply pipe 25 and 6, and an external vertical tubing chamber on the upper end is equipped with an onfusor 7, and the case 8, 9 cools the upper ends tubular cairns with confueors. In the lower part of the dry zone 8, an attorney 0 in the coarse fraction is installed under the convergers, and an aspiration opening is made in the upper part of the casing 9) 1, A nozzle 12 for the fine fraction is communicated with the base of the inner tubular chamber 4.

The separator works as follows .40

The material being separated under the action of the air flow is directed through the supply nozzle 6 into the ring bunker 3, where the flow is twisted and through the outer tubular chamber of the device between the outer vertical tube and the inner one enters zone A of the inter-confused space 5 and 7. the passage of the annular space by the material under the action of centrifugal forces of the swirling air flow is subjected to delamination (preliminary rough sorting), with

the bulk of the large fraction.

The coarse fraction settles on the surface of the confuser 7 of the outer vertical tubular chamber 1 and, under the action of centrifugal forces arising from its rotation by means of the drive 2, is instantly ejected into the interconfusion space, due to a decrease in the air flow rate due to the increase in the living cross section. a housing 8, from which a large frakhshchi is discharged from the device through the nozzle 10 port. The remaining mass of material, freed from coarse fractions of more than 5.0 mm (which is deposited on the surface of the confuser 7 and thrown into the casing 8), has passed the interfusion space, at the level of the upper section of the confuser 5 of the inner vertical tubular chamber 4, is divided into a fine fraction (1 , 0-5.0 mm) and pulverized (less than 1.0 mm). The dust fraction (1.0 mm) is carried away by the air flow, enters the upper part of the casing 9 and is withdrawn from the device through the aspiration hole 11. The fine fraction of 1.0-5p mm forms a suspended layer at the level of the upper cut-off of the confuser 5 of the inner vertical tubular chamber 4. which flows into the confuser 5, enters it and, under the action of gravity, is led out through the inner tubular chamber from the device through the nozzle 12 from the fine fraction.

A necessary condition for the effective separation of the conditioned fraction is to maintain it in the separation zone A in the Weighted state. When changing the physicomechanical properties of the material, to ensure this condition, it is necessary to adjust the pressure of the material of the air mixture, which is ensured by changing the angle between the confusors of the separation surface and the housing.

As confirmed by experimental data, when the physicomechanical properties of the technological chips change, the angle between the converters should be 5 to 35, and the chip fractions are optimally separated.
