This invention relates to the separation of powdered materials by size and can be used in cement, chemical and other industrial areas.

A separator is known, including a housing, a loading and unloading device, a working chamber made in the form of a cone, rotating vanes placed in the upper part of the housing f1J,.

The disadvantage of this separator is the low quality of the separation.

The closest to the proposed technical cjtaHqcTH and the achieved result is the air pass classifier, which includes an outer case with nozzles for feeding the air mixture, fine particles and collecting coarse fractions, an additional air supply nozzle with a regulating device, rotary vanes installed in the upper part of the outer case, the inner casing, while the nozzles for feeding the air mixture and additional air are concentrically mounted 2.

A disadvantage of the known classifier is that it lacks a centrifugal force field along the length of the material stream, with the exception of the upper zone, which reduces the quality of separation.

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

The goal is achieved by the fact that the separator is equipped with a louver nozzle installed between the air mixture supply pipe and the additional air supply pipe and additional rotary vanes installed in the middle part of the outer surface of the inner housing.

Figure 1 shows the separator, a general view; figure 2 - zhalyueiyna nozzle.

The separator includes an outer casing 1, a pipe 2 supplying the original mixture, the pipe 3 supply additional air. Between the nozzles 2 and 3 is installed louver nozzle 4, In the middle part of the outer surface of the inner part of the housing 5, additional blades 6 are installed.

Adjustable vanes 7 are installed in the upper part of the outer case. In the upper part of the inner case there is a nozzle 8 for collecting fines, connected to the cyclone

9. Supply of additional air is carried out with the help of a fan.

10 connected by pipe 11

with a pipe 3. To adjust the air supply in the pipe 11, a gate 12 and an air outlet 13 are installed. The supply of additional air is regulated by a device 14 mounted on the nozzle,

3. For the collection of large fractions in the lower part of the classifier is installed the pipe 15.

The separator works as follows.

The initial aerosol when injected into the separator through the pipe 2 is twisted with additional air passing through the louver

4. Further, the winding up of the aerosol mixture is supported by blades 6 installed in the middle part of the outer surface of the inner casing b. Dropping the mixture when entering from the nozzle 2 into the separator as a result of the increase in volume loses its velocity and at the same time the largest particles from noTQKa fall out. The swirled flow of the air mixture, freed from large particles, rises to the adjustable logs 7, in which large particles are finally released. By the inner case 5, after bending around the edge of the nozzle 8, fine particles with air are sent to cyclone 9, where small particles are deposited. The purified air from the cyclone is directed to the fan 10.

Large particles moving in the lower part of the separator are additionally cleaned with air exiting through the slots, the size of which is controlled by the device 14 mounted on the nozzle 3.

The use of the proposed separator will improve the quality of separation of materials.
