[0027] The embodiment of the present application discloses an air intake duct of a powder classifier.

[0028] Reference Figure 1-3 , an air intake pipe of a powder classifier, comprising a pipe body 1, a descaling device 2 is rotatably arranged in the pipe body 1, a pressurizing mechanism 3 is also arranged at the air intake end of the pipe body 1, a flange 4 is arranged at the air outlet end of the pipe body 1, and the pipe body 1 is fixed to the air intake end of the powder classifier through the flange 4;

[0029] The descaling device 2 comprises a rotating ring 21, a driving assembly 22 and a cleaning assembly 23. The rotating ring is rotatably mounted on the inner wall of the tube body 1. The driving assembly 22 drives the rotating ring to rotate. The cleaning assembly 23 is fixedly mounted on the inner wall of the rotating ring.

[0030] During use, after the tube body 1 is ventilated, the driving component 22 drives the rotating ring to rotate inside the tube body 1, and drives the cleaning component 23 to rotate inside the tube body 1 at the same time, which can effectively clean the dust particles on the inner wall of the tube body 1 when the tube body 1 is ventilated, and prevent the dust particles from adhering to the inner wall of the tube body 1 for a long time to form scale and affect the fluidity of the tube body 1.

[0031] Reference Figure 2-3 The cleaning component 23 includes multiple scrapers 231 and multiple brush plates 232. The multiple scrapers 231 and the multiple brush plates 232 are all circumferentially fixed in the rotating ring. The multiple scrapers 231 and the multiple brush plates 232 are spaced apart. When in use, the scrapers 231 can further remove dust particles and scale on the inner wall of the tube body 1, and the brush plates 232 can effectively clean the dust particles on the inner wall of the tube body 1.

[0032] More specifically, the two side surfaces of the scraper 231 are inclined toward the center, and the two sides of the scraper 231 are inclined toward the center from the air inlet end of the tube body 1 to the air outlet end of the tube body 1, which can effectively guide the discharge of scaling and accumulated dust particles when cleaning the inner wall of the pipeline.

[0033] Reference Figure 3 The driving assembly 22 includes an outer gear ring 221, a driving gear 222 and a motor 223. The motor 223 is fixedly arranged outside the tube body 1, the driving gear 222 is fixed to the output end of the motor 223, the outer gear ring 221 is fixedly arranged on the outer wall of the rotating ring, and the driving gear 222 is meshed and connected with the outer gear ring 221;

[0034] When in use, the motor 223 drives the driving gear 222 to rotate, and through the meshing transmission between the driving gear 222 and the outer gear ring 221, the rotating ring can be driven to rotate in the tube body 1, and the cleaning component 23 can be driven to clean the inner wall of the tube body 1.

[0035] Reference Figure 1-2 The boosting mechanism 3 includes a plurality of blowers 31, a ventilation duct 32 and a plurality of air outlets 33. The ventilation duct 32 and the air outlets 33 are both arranged in the tube body 1. One end of the ventilation duct 32 is connected to the plurality of blowers 31, and the other end of the ventilation duct 32 is connected to the plurality of air outlets 33.

[0036] During use, when the air volume and air pressure entering the tube body 1 are insufficient to support the normal operation of the powder classifier, the booster mechanism 3 is turned on to increase the air volume entering the tube body 1 to ensure stable operation of the powder classifier.

[0037] More specifically, the multiple air outlets 33 are all inclined toward the air outlet end of the tube body 1, which can effectively enable the blower 31 to quickly perform pressurized air blowing.

[0038] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
