A crushing body of revolution 4 is mounted on the shaft with a vibrator b. The fan 9 is in communication with the outlet pipe. Under the crushing rotary body 4, a perforated disk 7 is mounted on the parallel shaft of the rotational body of the shaft 13 for conveying the unfinished material under the action of the fan 10, in communication with the accumulation chamber 14, which serves to direct the underfinished material into the inlet pipe. The perforated disk is made with sectors having openings of different through sections. 1 s P. f-ly, 2 ill.

Description

Vi / t.f

The invention relates to a device for preparing dry aerosols, as well as aeration of air-powder and gas-powder mixtures, and can be widely used in agriculture and powder metallurgy.

The purpose of the invention is to improve cleaning efficiency and improve technological capabilities.

In FIG. 1 shows a proposed aerator, a longitudinal section; in FIG. 2 is an embodiment of a sieve with sectors containing sets of holes of different passage sections.

The aerosol aerator contains a housing 1 with an inlet 2 and an outlet in the form of a nozzle 3 nozzles, a crushing body 4 mounted in the housing 4 with a shaft 5, a vibrator b with a vibrator drive, a sieve in the inlet nozzle in the form of a perforated disk 7 with brushes 8. located above it , and two fans. 9 and 10 located on the vibrator body. The fan 9 is in communication with the space under the sieve by means of a nozzle 11 and with the outlet pipe. The fan 10 communicates with the part of the sieve to be cleaned by means of a nozzle 12. The perforated disk of the sieve 7 is mounted on an additional shaft 13 parallel to the shaft of the crushing body of revolution, which is rotated by means of a drive with a low number of revolutions (several revolutions per minute). The aerator is equipped with a storage chamber 14, communicated through openings 15 in the part of the sieve 7 with the fan 10. In addition, the disk 7 is made with sectors 16; containing sets of sizes of openings of different passage sections 17 and 18. A tray 19 is provided for backfill of powder material, in communication with the inlet nozzle 2. The neck 20 of the tray 19 is closed by a cover 21. On the vibrator is a driven pulley 22 of the V-belt drive.

The device operates as follows.

Through the neck 20 of the tray 19, the material is poured into the inlet pipe and closed with a cover 21. When the vibrator 6 is rotated, a centrifugal force is created, which provides oscillatory-rotational movement of the crushing rotation body. Aerosols are crushed by the rotation body and scattered onto a sieve in the form of a perforated

disk 7, sifted and sent by nozzle 11, communicated by line a and with fan 9 to the consumer through the outlet pipe in the form of nozzle 3. Larger particles of material that did not pass the sieve 7

when the disk is rotated, the sieves are directed by the fan 10 via line b and nozzle 12 to the accumulation tank 14, from where they can be directed through the valve c to the inlet pipe for reprocessing. The surface of the disc 7 is finally cleaned with a brush 8.

The operation of the device with a sieve with sectors containing holes of different passage sections is as follows. At

changing the conditions of the technological process, the disk is rotated by a predetermined angle, which ensures a given size of the aeration of the mixture, since the cross-sections of the holes above the aeration nozzle change

mixtures.

The cost-effectiveness of the device is ensured by eliminating the time of simply an aerator for cleaning the sieve from the coarse fraction.
