The output end of the motor 5 is fixedly connected to the center of the surface of the filter hole 41. It is used to control the rotation of the screening cylinder 4 through the cooperation of the gear 51 and the external gear ring 42.

[0030] In this utility model, a maintenance port 12 is provided on the top of one side of the screening box 1. A baffle 2 is rotatably connected to the surface of the maintenance port 12. A handrail 21 is installed on the surface of the baffle 2. An inclined plate 13 is fixedly connected inside the screening box 1. The inclined plate 13 is inclined. The maintenance port 12 is located at the higher end of the inclined plate 13. Two guide plates 15 are vertically fixedly connected to the lower end of the top of the inclined plate 13. A discharge pipe 16 is fixedly connected to the surface of the screening box 1. The discharge pipe 16 is located at the top of the lower end of the inclined plate 13.

[0031] In this invention, a second scraper 7 is rotatably connected inside the screening box 1. The second scraper 7 is horizontally arranged, and its bottom end is in contact with the inner wall of the screening cylinder 4. A rotating shaft 71 is fixedly connected to the top of the second scraper 7.

The two ends of the two torsion springs 73 are respectively fixedly connected to the two fixing plates 72 and the two end surfaces of the screening box 1 to restrict the rotation of the rotating shaft 71, thereby pressing the bottom end of the second scraper 7 against the inner wall of the screening cylinder 4, which can improve the passage of the brightener inside the screening cylinder 4.

[0032] In this utility model, vertical plates 31 are vertically fixedly connected to both ends of the waste box 3. A first scraper 32 is fixedly connected between the two vertical plates 31.

Subsequently, it is transported into the screening cylinder 4 through multiple discharge pipes 62. During use, the drive motor 5 is controlled to rotate the gear 51, which, in conjunction with the external gear ring 42, causes the screening cylinder 4 to rotate. At this time, the brightener transported into the screening cylinder 4 is screened by gravity through multiple filter holes 41 on the surface of the screening cylinder 4. Then, under the action of the second scraper 7, the brightener is squeezed downwards, making it easier for the brightener to pass through. The screening cylinder 4 screens downwards, thereby improving the efficiency of the device. As the screening cylinder 4 continues to rotate, the filtered material on the inner wall of the screening cylinder 4 rotates to the top of the waste box 3. There is a gap between the waste box 3 and the inner wall of the screening cylinder 4. The first scraper 32 inside the waste box 3 continuously contacts the inner wall of the screening cylinder 4, which can scrape off the impurities remaining on the inner wall of the screening cylinder 4, thereby improving the performance of the screening cylinder 4. The scraped impurities will slide down into the waste box 3 and then slide down through the waste box 3 to collect the impurities, thereby improving the performance of the device.

[0035] In summary, in this utility model, by rotating the screening cylinder 4, the multiple filter holes 41 provided on the surface of the screening cylinder 4 facilitate the continuous screening of the brightener conveyed into the screening cylinder 4, so that the impurities inside the brightener are filtered into the screening cylinder 4. Then, by setting the waste box 3 and the first scraper 32, the impurities filtered into the screening cylinder 4 can be removed, thereby improving the effectiveness of the device.
