[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figure 1 and Figure 5 An embodiment of this utility model provides a high-fineness slag powder grading and screening device for ball mills, including a top plate 1 and a base 8. A second motor 18 is provided on the inner wall of the base 8. An eccentric wheel 19 is provided at the output end of the second motor 18. A connecting block 17 is rotatably connected to the front side of the eccentric wheel 19. A second connecting rod 15 is rotatably connected to the outer wall of multiple connecting blocks 17. A rotating shaft 14 is rotatably connected to the inner wall of the second connecting rod 15. One end of the rotating shaft 14 is rotatably connected to the inner wall of the base 8. A sliding groove 20 is provided on the top of the base 8. A sliding component is provided at the bottom of the top plate 1. A connecting column 16 is rotatably connected to the outer wall of the connecting block 17. A grinding barrel 3 is provided at the bottom end of the connecting column 16. A cleaning component is provided on the inner wall of the grinding barrel 3.
[0026] Specifically, the second motor 18 is started, which drives the connecting block 17 through the eccentric wheel 19, thereby driving the second connecting rod 15 to move back and forth. Then, the second connecting rod 15, through another connecting block 17 and connecting column 16, carries the grinding barrel 3 to slide left and right in the sliding groove 20 on the base 8. The rotating shaft 14 limits the second connecting rod 15. In this way, the second motor 18 can realize the left and right swaying of the grinding barrel 3 through the eccentric wheel 19 and other structures.
[0027] Reference Figure 3The cleaning assembly includes support rods 10. One end of each support rod 10 is fixedly connected to the inner wall of the grinding barrel 3. A first motor 11 is provided on a similar side of the support rods 10. A drive shaft 12 is provided at the output end of the first motor 11. A screen 21 is rotatably connected to the outer wall of the drive shaft 12. A cleaning brush 13 is slidably connected to the upper surface of the screen 21. The inner walls of the cleaning brushes 13 are fixedly connected to the outer wall of the drive shaft 12. The outer walls of the screens 21 are fixedly connected to the inner wall of the grinding barrel 3.
[0028] Specifically, the first motor 11 drives the transmission shaft 12 to rotate the cleaning brush 13 on the surface of the screen 21, which can clean the surface of the screen 21 and prevent the accumulation of debris on the surface of the screen 21, which would cause blockage.
[0029] Reference Figure 1 and Figure 2 The sliding assembly includes support columns 22, with a top plate 1 at the top of the multiple support columns 22, a base 8 at the bottom of the multiple support columns 22, multiple springs 4 in the middle of the multiple support columns 22, and a first connecting rod 5 slidably connected to the middle of the multiple support columns 22. One end of the multiple first connecting rods 5 is fixedly connected to the outer wall of the grinding barrel 3.
[0030] Specifically, driven by the second motor 18, the grinding barrel 3 is made to sway left and right, and then the multiple first connecting rods 5 slide on the middle of the outer wall of the multiple support columns 22 under the action of multiple springs 4, so that the grinding barrel 3 can sway left and right while sliding up and down, thus achieving multi-directional swaying, in order to accelerate the screening speed of the multiple screens 21.
[0031] Reference Figure 4 The outer wall of the connecting column 16 is slidably connected to the inner wall of the slide groove 20, and the outer wall of the connecting column 16 is slidably connected to the inner wall of the base 8.
[0032] Specifically, by opening a sliding groove 20 on the inner wall of the base 8, driven by the second motor 18, the connecting column 16 slides repeatedly left and right on the inner wall of the base 8 through the sliding groove 20 with the cooperation of the connecting block 17, the second connecting rod 15, and the rotating shaft 14.
[0033] Reference Figure 1 The outer wall of the grinding barrel 3 is provided with multiple discharge pipes 7 that are connected to the inner wall.
[0034] Specifically, after the first motor 11 drives multiple screens 21 to screen the slag, discharge pipes 7 are set for screens 21 with different screen apertures to classify the slag with different apertures.
[0035] Reference Figure 1 The upper surface of the base 8 is provided with multiple collection pools 6.
[0036] Specifically, after the slag with different apertures is discharged by multiple discharge pipes 7, the slag with different apertures is collected at the same time, saving manpower and improving efficiency.
[0037] Reference Figure 1 The top plate 1 has a discharge port 2 in the middle.
[0038] Specifically, by setting a discharge port 2 on the top plate 1, the slag is poured into the grinding barrel 3 through the discharge port 2 to achieve the material discharge function.
[0039] Reference Figure 3 The top of the support rod 10 is equipped with a material distribution plate 9.
[0040] Specifically, the material distribution plate 9 is fixed to the top of the grinding barrel 3 by the support rod 10. When the material is discharged, the material is diverted by the material distribution plate 9, which slows down the falling speed of the material and reduces the impact on the screen 21, preventing the screen 21 from deforming.
[0041] Working principle: The second motor 18 drives the eccentric wheel 19 to drive the second connecting rod 15 through multiple hinged connecting blocks 17. The second connecting rod 15 is fixed and limited by the rotating shaft 14. The top of the base 8 is provided with a sliding groove 20. The multiple connecting blocks 17 drive the connecting column 16 to slide left and right on the inner wall of the base 8. When the material enters the grinding barrel 3 through the feeding port 2 and the distributing plate 9, the grinding barrel 3 is driven to slide on the support column 22 through the multiple second connecting rods 15 under the action of multiple springs 4. In this way, under the action of the eccentric wheel 19, the multiple connecting blocks 17 carry the second connecting rod 15 to reciprocate. At the same time, the connecting column 16 drives the grinding barrel 3 to reciprocate up and down on the outer wall of the support column 22. The above structure works together to realize the vibration of the grinding barrel 3, thereby accelerating the screening of the multi-layer screen 21, improving the working efficiency, and preventing the screen 21 from clogging.
[0042] This invention involves pouring slag into the discharge port 2. A support rod 10 holds the distribution plate 9 to the top of the grinding barrel 3. As slag is fed from the discharge port 2 onto the distribution plate 9, it is diverted, reducing the impact of the slag on the screen 21 and preventing deformation. A first motor 11 drives the transmission shaft 12, which in turn drives multiple cleaning brushes 13 to clean the surfaces of the multiple screens 21, preventing accumulation and ensuring smooth operation. Screens 21 with different apertures separate slag of varying sizes through multiple discharge pipes 7, collecting it in multiple collection pools 6 for simultaneous screening of slag of different sizes.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
