[0024] The anti-blocking component 4 includes a rotating plate 5. Several partitions 6 are installed at the bottom of the rotating plate 5. The partitions 6 are evenly distributed in a ring array and placed at an angle. A toothed plate 7 is installed on the top of the rotating plate 5. A gear 8 is installed in the meshing of the teeth of the toothed plate 7. A rotating rod 9 is installed through the center of the gear 8. A drive motor 10 is installed on the top of the rotating rod 9. The drive motor 10 is located on the top of the fixed ring box 3.

[0025] During use, cement raw materials are poured into the interior of the fixed ring box 3 through the feed pipe 11 after passing through the vertical mill. The anti-blocking component 4 accelerates the movement of the cement raw materials to the feed inlet 2 while preventing the cement raw materials from accumulating at the feed inlet 2 and blocking it, which would affect the feeding efficiency of the sorting box 1. The anti-blocking component 4 drives the rotating rod 9 to rotate through the drive motor 10. The rotating rod 9 drives the gear 8 to rotate. The gear 8 drives the tooth plate 7 to rotate through tooth meshing, which in turn drives the rotating plate 5 to rotate, causing the partition plate 6 at the bottom of the rotating plate 5 to rotate. The partition plate 6 facilitates the rapid movement of the cement raw materials.

[0026] Example 2

[0027] Based on Embodiment 1, an adjustable baffle 13 is provided to prevent cement raw materials from flowing out of the feed pipe 11 when moving. Several feed pipes 11 are evenly distributed in a ring array on the outer surface of the fixed ring box 3. The top of the feed pipe 11 is provided with a movable groove 12. The baffle 13 is installed inside the movable groove 12. Several springs 14 are installed on the top of the baffle 13. The springs 14 provide a downward thrust to the baffle 13. The springs 14 are symmetrically placed on both sides of the baffle 13 and evenly distributed in an array. The bottom of the springs 14 is fixed to the top of the feed pipe 11.

[0028] When in use, the baffle 13 moves downward under the force of the spring 14, passes through the inside of the movable groove 12 and blocks the feed pipe 11. When cement raw materials need to be introduced, the baffle 13 can be pulled to easily connect the feed pipe into the inside of the feed pipe 11. At the same time, the baffle 13 can fix and clamp the feed pipe.

[0029] Example 3

[0030] Based on Embodiment 2, a screen anti-clogging structure is provided. A coarse powder outlet 15 is installed at the bottom of the sorting box 1. A medium-fine powder outlet 16 and a fine powder outlet 17 are installed on the side wall of the sorting box 1. The fine powder outlet 17 is located above the medium-fine powder outlet 16. A medium-hole screen 18 and a fine-hole screen 19 are installed inside the sorting box 1. The medium-hole screen 18 and the fine-hole screen 19 are inverted funnel shapes. The fine-hole screen 19 is located directly above the medium-hole screen 18. The medium-fine powder outlet 16 is located on the side wall of the medium-hole screen 18. The fine powder outlet 17 is located on the side wall of the fine-hole screen 19. A sorting structure 20 is installed inside the sorting box 1. A movable scraper 21 is installed on the outer surface of the sorting structure 20. The movable scraper 21 is located on the upper surface of the medium-hole screen 18 and the fine-hole screen 19.

[0031] During use, after the cement raw meal enters through the feed inlet 2, the raw meal of different particle sizes is screened by the sorting structure 20 through the medium-hole screen 18 and the fine-hole screen 19. The coarse powder is discharged from the coarse powder outlet 15 at the bottom of the sorting box 1, while the medium-fine powder and fine powder are screened by the medium-hole screen 18 and the fine-hole screen 19 respectively and discharged from the medium-fine powder outlet 16 and the fine powder outlet 17 respectively. The movable scraper 21 is driven to rotate by the sorting structure 20 to prevent the screen holes from being blocked.

[0032] Working principle: In actual use, after passing through the vertical mill, the cement raw material is poured into the interior of the fixed ring box 3 through the feed pipe 11. The anti-blocking component 4 accelerates the movement of the cement raw material to the feed inlet 2 while preventing it from accumulating and blocking the feed inlet 2, which would affect the feeding efficiency of the sorting box 1. The baffle 13 moves downward under the force of the spring 14, passing through the interior of the movable groove 12. When cement raw material needs to be introduced, pulling the baffle 13 facilitates the connection of the feed pipe to the feed pipe 11. Meanwhile, the baffle 13 can fix and clamp the feed pipe. After the cement raw meal enters from the feed inlet 2, under the action of the sorting structure 20, the raw meal of different particle sizes is screened through the medium hole screen 18 and the fine hole screen 19, so that the coarse powder is discharged from the coarse powder outlet 15 at the bottom of the sorting box 1, and the medium and fine powders are screened through the medium hole screen 18 and the fine hole screen 19 respectively and discharged from the medium and fine powder outlet 16 and the fine powder outlet 17 respectively. The movable scraper 21 is driven to rotate by the sorting structure 20 to avoid the screen holes being blocked.
