Abstract

The invention relates to chemical technology and improves processing performance. From the hopper 1, through the nozzles 2, the material rises between the rotating thermostat 3 and the cylinder 5. On the smooth surface of the thermostat 3, the material is distributed in a thin layer and is crushed when pressed between the thermostat 3 and the cylinder 5, as well as under the influence of the vibrator 4. 5 and the engine to cut 7, where the gas exposure occurs. The treated material is collected in reservoir 11, and gas is discharged through pipe 10. 2c. and 1z.p. f-ly, I ill.

The invention relates to chemical or physical processes of general purpose, carried out in the presence of gas and solid particles, namely processes with particles set in motion in rotating drums, and can be used both in research institutions and in manufacturing. preparations for treating various bulk materials with gas (for example, reduction, oxidation, chlorination, etc.),

The purpose of the invention is to increase the processing efficiency.

The drawing shows a schematic of a device for treating powdered materials.

The device contains a hopper 1 for powdered material, nozzles 2 for spraying powder, a smooth cylindrical rotating thermostat 3, a horizontal vibrator 4, a perforated rotating cylinder 5, an internal cylinder 6 with a horizontal slot 7, a movable built-in tube 8 for supplying gas from a tank 9 , a gas outlet 10 and a reservoir 11 for treated material.

The device works as follows.

From the hopper 1, the powdered CuO material through the nozzles 2 flows between a rotating cylindrical thermostat 3 (D 0.2 m) and a perforated rotating cylinder 5 (D 2) with a rotation speed of V 5 rpm driven by electric motors. On the smooth surface of thermostat 3, the processed material is distributed in a thin layer, which allows it to be heated to a temperature of 250 ° C for a short period of time. When compressing the particles of material between the thermostat 3 and the perforated cylinder 5, they are crushed, which is facilitated by the operation of the horizontal vibrator 4, the crushed particles of the material being processed fill

the holes of the perforated cylinder 5 (d) and move with it to the horizontal notch 7, In the inner cylinder 6 from the reservoir 9 through the movably mounted tube 8 the gas H is fed, which passes through the material in the perforated holes of the cylinder 5 and at the same time cleans the holes from waste material in the lower part of the zone of contact between thermostat 3 and cylinder 5. The treated material enters the tank 11, and the screw pipe 10 removes gas N. For particularly fine particles on pipe 10 it is advisable to navlivat filter (not shown) in order to avoid the removal of the treated material with the gas in an aerosol state.
