[0026] The sliding rail 1 7 and the sliding rail 2 9 are provided with opposing protruding structures at their contact positions. The cross-section of the protruding structure is a convex structure inclined at ninety degrees. A rotating hole is provided in the middle of the sliding rail 1 7.

[0027] This device is further configured such as Figure 5 , Figure 6As shown, the stationary blade mechanism 8 includes a slide 12, a fixing rod 13 is provided at the bottom of the slide 12, a limit plate 14 is installed at the end of the fixing rod 13 by screws, the fixing rod 13 is provided with threads, and a fastening nut 15 is installed by the threads.

[0028] The stationary blade mechanism 8 also includes an adjusting seat 16, which is installed on the top of the slide 12. A bevel gear 18 is rotatably installed inside the adjusting seat 16. A rotating hole is provided on the side of the adjusting seat 16, and a bevel gear 19 is rotatably installed inside the hole. The bevel gear 19 meshes with the bevel gear 18.

[0029] The end of bevel gear 2 19 away from bevel gear 1 18 is provided with a cross hole;

[0030] The stationary blade mechanism 8 also includes moving and stationary blades 17. A bracket is mounted on the top of the bevel gear 18, and the moving and stationary blades 17 are bolted to the end of the bracket of the bevel gear 18. Several stationary blade mechanisms 8 are installed between slide rail 1 7 and slide rail 2 9. By sliding the stationary blade mechanisms 8, the distance between the stationary blade mechanisms 8 can be adjusted. Then, the slide block 12 is fixed with a fastening nut 15, which facilitates the adjustment of the number and spacing of the stationary blade mechanisms 8 according to processing needs, thereby adjusting the coal powder separation efficiency. By rotating the bevel gear 2 19, the bevel gear 2 19 drives the bevel gear 18 to rotate, which in turn drives the moving and stationary blades 17 to rotate together, achieving a high degree of precision adjustment of the offset angle of the moving and stationary blades 17, thereby adjusting the separation efficiency of the separator. At the same time, it is convenient to replace the moving and stationary blades 17, improving maintenance efficiency.

[0031] This device is further configured such as Figure 2 As shown, the moving blade mechanism includes a connecting rod 6 and a servo motor 5.

[0033] Working principle: During the separation of pulverized coal, the servo motor 5 drives the connecting rod 6 to rotate through the pulley mechanism 20. The connecting rod 6 drives the moving blade 11 to rotate, thereby driving the airflow to rotate. The pulverized coal collides with the 008 under centrifugal force, separating the pulverized coal from the slag. The slag is conveyed to the coal mill through the discharge port 2 4 for further grinding. The separated pulverized coal is conveyed out through the discharge port 1 2 under the action of the airflow blown into the coal mill and the airflow brought by the rotation of the moving blade 11. When installing the stationary blade mechanism 8, the distance between the stationary blade mechanisms 8 is adjusted by sliding the stationary blade mechanism 8. Then, the slide 12 is fixed with the fastening nut 15, which makes it easy to adjust the number and spacing of the stationary blade mechanism 8 according to the processing needs. By rotating the bevel gear 2 19, the bevel gear 2 19 drives the bevel gear 18 to rotate, which in turn drives the moving and stationary blades 17 to rotate together, so as to achieve a high degree of precision in adjusting the offset angle of the moving and stationary blades 17.
