The rotor structure of the friction powder removing device can improve the uniformity and efficiency of powder removing. In the process of high-speed rotation of the friction blades 4 in the shell toothed plate 2, the friction powder removing device shears, kneads and rubs materials to enable powder to fall off, and the metal foil clusters are particle pellets. The rotor cutterhead is arranged at the discharge end of the 5 rotating shaft and has a certain inclination angle, and negative pressure air flow is formed during operation to convey materials into the air flow classifier through a pipeline. The rotor cutterhead is arranged concentrically in sequence in the friction powder removing machine, and the structure of the concentric arrangement is as follows: the center holes penetrate through the same shaft; the multi-group staggered rotor cutterhead is arranged on the transmission shaft, so that the materials can be fully destoner.

When the present utility model is used, the motor 6, the variable frequency motor 12, the fan 17, and the respective shutters (shutter A7, shutter B14, shutter C16) in the system are sequentially started, and the system starts to operate. The materials are fed from a feed inlet 1, and the friction powder removing machine is operated to form negative pressure air flow inside; the material smoothly enters the mechanical friction powder removing machine by the action of negative pressure air flow, and the mechanical friction powder removing machine comprises: the shell is internally provided with a shell wall toothed plate 2 (the shell wall toothed plate 2 is of a tooth-shaped structure), a friction blade 4 is arranged on a friction tool rest 5 through a pin to form a rotor, a cutter head is convenient to replace, and the friction blade 4 is matched with the shell wall toothed plate 2 to form shearing, kneading and friction on materials.
The materials are pumped into the airflow classifier from the friction powder removing machine through negative pressure airflow, and the materials are collided and dispersed by the material blocking cone 9. The variable frequency motor 12 drives the classifying turbine 11 to rotate at a high speed in the classifying housing 10, and a strong centrifugal air flow is formed in the air flow classifier. Large metal particles in the airflow field are thrown 13 out of the classifying turbine due to the fact that the centrifugal force born by the large metal particles is larger than the resistance generated by the airflow to the large metal particles, so that the large metal particles are thrown to the periphery of the classifying turbine and the classifying shell 10, naturally fall into the air closer A7 under the action of gravity and are discharged and collected; the classifying turbine blades form a certain angle to generate upward cyclone airflow and negative pressure air generated by the fan 17, and fine powder materials are sucked into the cyclone collector from the discharge port through the negative pressure air. If the air quantity generated by the friction powder removing machine cannot meet the negative pressure air generated by the classifying turbine 11 and the fan 17, the air supplementing port 8 can be opened to adjust the air quantity as required. The centrifugal force in the air classifier can be adjusted by adjusting the rotating speed of the classifying turbine 11 through the variable frequency motor 12; the speed of the air flow is controlled by the speed of the stage turbine 11 and the fan 17; the classifying turbine 11 can adjust parameters such as the size of the blades, the inclination angle of the classifying blades and the like; the purpose of screening and separating the particle size of the specified material is achieved.
After the fine materials are sucked into the cyclone collector 13 from the airflow classifier under negative pressure, the airflow reaches the wall surface to make rotary motion in the cyclone collector 13, the airflow makes rotary motion from top to bottom along the wall surface under the action of centrifugal force and gravity, and after the powder materials reach the bottom of the cone, the suction wind generated by the fan 17 turns upwards and finally is discharged through the discharge pipe. When the downward air flow rotates, the fine powder materials are thrown to the outer wall under the pushing of inertial centrifugal force. After reaching the outer wall, the powder falls into the air shutter B14 along the wall surface in a rotating way under the action of gravity, so that the powder collecting effect of the device is achieved. The cyclone collector can be used for adjusting and collecting material effects through parameters such as the size of an inlet and outlet, the height of a cylinder and the outer diameter of a cone, and the like, so that the purpose of further finely separating dust particles of different types is achieved. Simultaneously, two or more cyclone collector devices are used for parallel connection at the same time, so that the collection effect is better.
The separated gas is discharged into a filter dust collector 15 under negative pressure, the gas used by the friction powder removing and sorting system is filtered, and the powder generated by the filtered gas falls into a wind blocking device C16 to enter a collecting pipe 22 and is discharged for collection. The filtered gas is discharged through an exhaust pipe 18 of the fan 17, one side of the exhaust pipe 18 is provided with a return air pipe 21, the filtered gas is discharged into the return air pipe 21 through a pipeline and is discharged into the feed inlet 1 through the pipeline, and the gas can be recycled.
