[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 5The present invention includes a compressor body 1, a separate compression structure body 2 fixedly installed at the rear of the compressor body 1, an air inlet pipe 3 fixedly installed at the upper part of the separate compression structure body 2, the air inlet pipe 3 can intake air from the lower end, and an installation cover 4 fixedly installed at the bottom of the air inlet pipe 3. The installation cover 4 is provided with a filter plate 9 inside, which can filter out dust in the airflow. A baffle 8 is fixedly installed on one side of the bottom of the installation cover 4, which isolates the lower surface of the filter plate 9 into two areas. A dust collection hopper 6 is fixedly installed at the bottom of the baffle 8, and a discharge pipe 7 is fixedly installed at one end of the dust collection hopper 6. The cleaned dust will enter the discharge pipe 7 through the dust collection hopper 6 and be discharged away. An installation cylinder 12 is fixedly installed on one side of the top of the installation cover 4 through an air inlet cover 10. A fan 13 is provided inside the installation cylinder 12, which can rotate and blow air.

[0023] A support arm 14 is fixedly installed on the top of the mounting cylinder 12. A servo motor 15 is fixedly installed at one end of the top of the support arm 14. The servo motor 15 can output rotational power stably and accurately. The output end of the servo motor 15 is provided with a transmission component. The transmission component is connected to the fan 13 and the filter disc 9. When the servo motor 15 is running, it can drive the fan 13 and the filter disc 9 to rotate, so as to realize the real-time cleaning of the filter disc 9. Several diverter plates 11 are fixedly installed inside the air inlet cover 10. Several diverter plates 11 can guide the airflow in different directions to improve the uniformity of the airflow blown out by the fan 13. A slip ring 16 is fixedly installed on the circumferential surface of the filter disc 9. An annular groove 17 is opened on the inner wall of the mounting cover 4. The slip ring 16 is slidably installed inside the annular groove 17, so that the slip ring 16 can rotate and slide in the annular groove 17 to ensure the stability of the rotational transmission of the filter disc 9.

[0024] When the main body 2 of the separation compression structure is in operation and intakes air, the dust in the air can be filtered down by the filter disc 9. At the same time, the operator starts the servo motor 15 to run. The servo motor 15 drives the filter disc 9 to rotate through the transmission component. When the filter disc 9 rotates, it drives the slip ring 16 to rotate and slide inside the ring groove 17 to increase the stability of the filter disc 9 when rotating. When the filter disc 9 rotates, it will carry the dust attached to its surface to the area above the baffle 8.

[0025] While the transmission components are running, the fan 13 will also rotate rapidly to blow airflow into the air inlet shroud 10. The airflow is evenly guided to the filter disc 9 through several diverter plates 11. The airflow back-blowing can blow the dust attached to the filter disc 9 into the dust collection hopper 6 and discharge it through the discharge pipe 7 for collection. This allows the filter disc 9 to rotate continuously during the filtration process to clean the dust on its surface, so that the clean surface can be continuously adjusted for filtration, preventing dust from adhering and causing blockage, and improving the filtration effect and efficiency.

[0026] The transmission assembly includes a first sprocket 18 fixedly installed at the output end of the servo motor 15. A shaft 19 is fixedly installed at the bottom of the first sprocket 18. Bearings 20 are rotatably installed at both ends of the surface of the shaft 19. The two bearings 20 are fixedly connected to the air inlet pipe 3 and the mounting cover 4 respectively to achieve rotational positioning of the shaft 19. The bottom end of the shaft 19 extends downward into the interior of the mounting cover 4 and is fixedly connected to the top of the filter disc 9, so that the shaft 19 can drive the filter disc 9 to rotate.

[0027] The operator starts the servo motor 15, which drives the shaft 19 to rotate through the first sprocket 18. When the shaft 19 rotates, it drives the filter disc 9 to rotate. When the filter disc 9 rotates, it will carry the dust attached to its surface to the area above the baffle 8.

[0028] A second sprocket 21 is rotatably mounted on the inner bottom of the mounting cylinder 12. A chain 22 meshes with the first sprocket 18, and the chain 22 transmits the power of the first sprocket 18 to the second sprocket 21. A drive gear 27 is fixedly mounted on the bottom of the second sprocket 21. The bottom of the drive gear 27 is rotatably connected to the inside of the mounting cylinder 12 through a rotating seat 23, so that the drive gear 27 can rotate along the rotating seat 23 to ensure the stability of the rotation of the drive gear 27. A driven gear 5 is meshed on one side of the drive gear 27. The diameter of the drive gear 27 is three times larger than the diameter of the driven gear 5. A rotating shaft 24 is fixedly mounted on the bottom of the driven gear 5. The bottom of the rotating shaft 24 is fixedly connected to the fan 13 to drive the fan 13 to rotate and blow air. A bearing seat 25 is rotatably mounted on the surface of the rotating shaft 24, and the surface of the bearing seat 25 is fixedly connected to the inside of the mounting cylinder 12 through two support rods 26 to achieve rotational positioning of the rotating shaft 24.

[0029] While the first sprocket 18 rotates, it also drives the second sprocket 21 to rotate via the chain 22. When the second sprocket 21 rotates, it drives the driven gear 5 to rotate via the driving gear 27. Since the diameter of the driving gear 27 is three times that of the driven gear 5, the driven gear 5 can rotate quickly. When the driven gear 5 rotates quickly, it drives the fan 13 to rotate quickly via the rotating shaft 24 to blow air into the air inlet shroud 10. The filter disc 9 can be cleaned by the backflushing air.
