[0034] The centers of the collecting cover 5, the first rotating block 8 and the second rotating block 9 are on the same line.

[0035] The working principle of the present invention is:

[0036] The high-temperature impure compressed air from the air compressor enters the collecting cover 5 from the air inlet 6 for short-term storage, and flows from the air inlet channel 10 to the temporary storage chamber 11 at high speed, and is blocked by the oil-blocking net 13, and the purified compressed air is finally discharged from the end of the second rotating block 9; in the process of compressed air flow, the starting motor 18 drives the output shaft 20 to rotate, and then drives the driving gear 21 to rotate, and then drives the driven gear 16 to rotate, and then drives the collecting cover 5, the first rotating block 8 and the second rotating block 9 to rotate. The impure compressed air will be separated under the action of centrifugal force. First, the high-temperature compressed air will be cooled, and the water vapor in the airflow will be Condensed into water droplets adhere to the inner walls of the air intake channel 10 and the temporary storage chamber 11; secondly, the oil particles in the air flow will also be condensed into liquid droplets due to cooling and hit the inner walls of the air intake channel 10 and the temporary storage chamber 11 and be adhered; thirdly, the solid particles in the air flow will also hit the inner walls of the air intake channel 10 and the temporary storage chamber 11. Since the inner walls of the air intake channel 10 and the temporary storage chamber 11 are covered with water and oil, the dust particles will inevitably be adhered to them. After being adhered, the impurities in the impurity-containing compressed air will flow into the temporary storage chamber 11 and be gathered and thrown out from the sewage tank 12 to the top box 3. The impurities can be discharged from the sewage pipe 14 by adjusting the butterfly valve 15, thereby greatly improving the filtering efficiency of the compressed air;

[0037] When the output shaft 20 is rotated by the starter motor 18, the first bevel gear 22 and the second bevel gear 23 are driven to rotate, thereby driving the brush 25 to rotate and continuously cleaning the impurities attached to the top wall of the top box 3 for the second time, so that the impurities are gathered to the bottom of the top box 3, so that the impurities can be well guided to facilitate the maintenance and care of the equipment in the later stage;

[0038] The elastic steel plate 27 can reduce the longitudinal vibration of the device, and the vibration reduction device 28 can reduce the lateral vibration of the device, thereby increasing the service life of the equipment.
