DETAILED DESCRIPTION

[0028] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail with reference to the drawings.

[0029] The present application provides aFigures 1-6 A chemical raw material grinding apparatus shown includes:

[0030] Box 1, with a feed hopper 2 at the top and a discharge port 3 at the bottom;

[0031] Support legs are provided at all four ends of the bottom side of the box 1.

[0032] The first grinding mechanism includes a grinding cylinder 4 rotatably mounted at the bottom of the feed hopper 2 and located inside the housing 1. A first rotating component is provided at the top of the grinding cylinder 4, and a conical grinding roller 6 is provided in the middle of the interior of the grinding cylinder 4. A support frame 27 is fixedly connected between the top of the conical grinding roller 6 and the feed hopper 2. A second grinding head 7 is provided on the outer wall of the conical grinding roller 6, and a first grinding head 5 facing the second grinding head 7 is provided on the inner wall of the grinding cylinder 4.

[0033] The first rotating assembly includes a first gear ring 10 disposed at the top of the grinding cylinder 4. A first motor 8 is fixedly connected to the inside of the housing 1 near the grinding cylinder 4 via a bracket. The output end of the first motor 8 is connected to a first gear 9, and the first gear 9 meshes with the first gear ring 10.

[0034] In use, chemical raw materials can be poured into the housing 1 through the feed hopper 2. The material then falls between the grinding cylinder 4 and the conical grinding roller 6. The first gear 9 is driven to rotate by the first motor 8, which in turn drives the first gear ring 10 to rotate. The first gear ring 10 then drives the grinding cylinder 4 to rotate, thereby allowing the grinding cylinder 4 and the conical grinding roller 6 to rotate relative to each other. Since the distance between the first grinding head 5 and the second grinding head 7 gradually decreases from top to bottom, the material can be continuously ground and crushed through the squeezing action between the grinding head 5 and the material, resulting in a better grinding effect.

[0035] The second grinding mechanism includes a grinding frame 14 rotatably installed inside the housing 1 near the bottom of the grinding cylinder 4. The grinding frame 14 is provided with a second rotating component, and a sieve plate 15 is provided at the bottom of the inner side of the grinding frame 14. A grinding ring 16 is provided inside the sieve plate 15, and a grinding block 17 is provided inside the grinding ring 16.

[0036] The second rotating assembly includes a second gear ring 13 disposed on the outer wall of the grinding frame 14. A second motor 11 is disposed inside the housing 1 on the side near the grinding frame 14. The output end of the second motor 11 is connected to a second gear 12, and the second gear 12 meshes with the second gear ring 13.

[0037] A protective frame 18 is provided inside the grinding frame 14, and the protective frame 18 is located above the grinding ring 16. Based on this, the protective frame 18 can intercept the grinding ring 16 and the grinding block 17 to prevent them from falling out of the grinding frame 14.

[0038] After being ground and crushed through multiple stages, the material falls from the grinding cylinder 4 into the grinding frame 14 below. The second motor 11 drives the second gear 12 to rotate, which in turn drives the second gear ring 13 to rotate. The second gear ring 13 then drives the grinding frame 14 to rotate. Under the action of centrifugal force, the grinding ring 16 rotates along the inner wall of the grinding frame 14, while the grinding block 17 rotates along the inner wall of the grinding ring 16. This allows the grinding ring 16 and the grinding block 17 to collide and crush the material falling into the grinding frame 14, thereby further grinding the material and greatly improving the grinding precision of the chemical raw materials.

[0039] An arc-shaped screen 19 is provided inside the housing 1 and between the grinding frame 14 and the discharge port 3. A pressing mechanism is provided on the arc-shaped screen 19.

[0040] The pressing mechanism includes a connecting frame 21, with a pressure roller 22 rotatably connected to the bottom end of the connecting frame 21. Both ends of the connecting frame 21 are fixed with connecting shafts 20. Both connecting shafts 20 are movably connected to the housing 1 through bearings. The pressure roller 22 rolls and engages with the inner side of the arc-shaped screen 19. A third motor 23 is fixed to the outer side of the housing 1. A handle 24 is connected to the output end of the third motor 23. A guide post 25 is fixed to one end of the handle 24 relative to the output shaft of the third motor 23. One end of one of the connecting shafts 20 extends to the outside of the housing 1 and is provided with a guide frame 26. The guide post 25 is slidably engaged within the guide frame 26.

[0041] The material to be ground again in the grinding frame 14 can fall onto the arc screen 19 through the screen plate 15. The rotating handle 24 is driven by the third motor 23 to make a circular motion, which can make the rotating handle 24 drive the guide column 25 to slide back and forth in the guide frame 26. Then the guide frame 26 drives the connecting shaft 20 to swing left and right, which can make the connecting shaft 20 drive the pressure roller 22 to roll back and forth on the arc screen 19 through the connecting frame 21. Thus, the material can be crushed and ground into extremely fine particles and powders again. Finally, the particles and powders pass through the screen holes and are discharged from the discharge port 3, thus fully and effectively realizing the grinding and processing of chemical raw materials with high precision, which greatly improves the use effect of the grinding device.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
