[0002] Grinding equipment is frequently used in the daily production and processing of chemical raw materials. By placing the chemical raw materials into the grinding equipment for grinding, the produced raw materials become finer, improving the production quality and processing efficiency. A grinding device typically includes a grinding jar and grinding discs. The grinding discs are placed inside the grinding jar and consist of two discs, upper and lower. The chemical raw materials are loaded between the upper and lower grinding discs, and a motor drives the rotation of the upper and lower grinding discs to grind the chemical raw materials.

[0003] The grinding gap between the upper and lower grinding discs of existing grinding devices is fixed and cannot be flexibly adjusted according to the grinding requirements of different chemical raw materials. This results in poor adaptability to raw materials with various particle size requirements, requiring the replacement of different equipment to complete the processing, which increases production costs and operational complexity.

[0004] In addition, after the existing grinding equipment has finished grinding, raw material debris is easily left on the surface of the grinding disc and the inner wall of the grinding jar, making cleaning difficult. Utility Model Content

[0028] See attached document Figure 1 -Appendix Figure 5 The present invention provides a chemical production raw material grinding device, including a grinding tank 1, wherein a grinding mechanism is provided inside the grinding tank 1;

[0029] The grinding mechanism includes an upper grinding assembly and a lower grinding assembly. The upper grinding assembly includes a rotating sleeve 19, which is disposed inside the grinding jar 1. The rotating sleeve 19 passes through the top of the grinding jar 1 and is slidably connected to the connection point of the grinding jar 1. An upper grinding disc 17 is fixedly mounted on the bottom of the rotating sleeve 19. A top frame 5 is fixedly mounted on the top of the grinding jar 1. A first motor 6 is fixedly mounted on the top of the top frame 5. A transmission rod 21 is fixedly connected to the output end of the first motor 6. One end of the transmission rod 21 is connected to the top of the grinding jar 1 via a bearing. A second gear 22 is fixedly mounted on the outside of the transmission rod 21. A first gear 20 is fixedly mounted on the outside of the rotating sleeve 19. The second gear 22 meshes with the first gear 20. The rotating sleeve 19 is connected to a connecting plate 11 via a bearing. Two hydraulic push rods 10 are fixedly mounted on the top of the top frame 5. The output end of the hydraulic push rods 10 is fixedly connected to the connecting plate 11. The lower grinding assembly includes a base frame 3, which is fixedly mounted on the bottom of the grinding tank 1. A second motor 12 is mounted on the top of the base frame 3. A transmission shaft 13 is fixedly connected to the output end of the second motor 12. The transmission shaft 13 extends into the interior of the grinding tank 1. A lower grinding disc 16 is fixedly connected to one end of the transmission shaft 13. The gap between the lower grinding disc 16 and the upper grinding disc 17 gradually decreases from the center outwards.

[0030] In this embodiment, the distance between the lower grinding disc 16 and the upper grinding disc 17 is pre-adjusted. Specifically, the hydraulic push rod 10 is activated, and the output end of the hydraulic push rod 10 extends and retracts, causing the connecting plate 11 to move up and down. Since the connecting plate 11 is connected to the rotating sleeve 19 through the bearing, the rotating sleeve 19 will rise and fall synchronously with the connecting plate 11, thereby driving the upper grinding disc 17, which is fixed at the bottom of the rotating sleeve 19, to rise and fall, thereby adjusting the distance between the upper grinding disc 17 and the lower grinding disc 16. During this process, the first gear 20 outside the rotating sleeve 19 always maintains a meshing state with the second gear 22 on the transmission rod 21, ensuring that the subsequent power transmission is not affected.

[0031] To achieve the purpose of support, the device adopts the following technical solution: the transmission shaft 13 is fitted with a first support frame 14 through a bearing, the first support frame 14 is fixedly connected to the inner wall of the grinding tank 1, and the transmission shaft 13 is supported and limited by the first support frame 14 to improve the rotational stability of the lower grinding assembly.

[0032] To achieve the purpose of support and limiting, the device adopts the following technical solution: a sliding groove 24 is provided on the outside of the rotating sleeve 19, and an inner sliding ring 23 is fitted on the outside of the rotating sleeve 19. The inner sliding ring 23 is slidably connected to the rotating sleeve 19. A second support frame 18 is fitted on the outside of the inner sliding ring 23 through a bearing. The second support frame 18 is fixedly connected to the inner wall of the grinding tank 1. The inner sliding ring 23 is slidably connected to the sliding groove 24 on the rotating sleeve 19, which does not affect the rotation of the rotating sleeve 19, but also provides support and limiting for it.

[0033] To achieve the cleaning purpose, the device employs the following technical solution: A cleaning assembly is provided on one side of the grinding tank 1. The cleaning assembly includes a compressor 8, which is fixedly mounted on the top of the top frame 5. An air supply pipe 9 is fixedly connected to the output end of the compressor 8. A support rod 26 is fixedly connected to one end of the air supply pipe 9. The support rod 26 is connected to the lower grinding disc 16 via a bearing. Multiple air vents 25 are provided on the outer surface of the air supply pipe 9. When the compressor 8 on the top of the top frame 5 is started, the high-pressure gas generated by the compressor 8 is transported through the air supply pipe 9 and ejected through the multiple air vents 25 on the surface of the air supply pipe 9. This blows and cleans the lower grinding disc 16, the upper grinding disc 17, and the inner wall of the grinding tank 1, removing residual raw material debris to prepare for the next batch of grinding operations.

[0034] In order to achieve the purpose of blocking, the device adopts the following technical solution: a baffle 15 is fixedly provided on the inner wall of the grinding tank 1. The baffle 15 can effectively block the powder from splashing upward, avoiding raw material waste and equipment contamination.

[0035] In order to achieve the purpose of feeding, the device adopts the following technical solution: the top of the top frame 5 is fixedly provided with a feeding pipe 7, the feeding pipe 7 passes through the top frame 5 and extends into the interior of the rotating sleeve 19, and the chemical raw materials to be ground are added into the device through the feeding pipe 7 at the top of the top frame 5. The raw materials enter the interior of the rotating sleeve 19 through the feeding pipe 7 and finally fall on the surface of the lower grinding disc 16.

[0036] To achieve the purpose of support, the device adopts the following technical solution: multiple support columns 4 are fixedly provided at the bottom of the grinding tank 1, which provide stable support for the entire device and ensure that the device remains stable during operation.

[0037] In order to achieve the purpose of material discharge, the device adopts the following technical solution: the bottom of the grinding tank 1 is fixedly provided with a discharge pipe 2, and the drive shaft 13 passes through the discharge pipe 2 and extends into the interior of the grinding tank 1.

[0038] The usage process of this utility model is as follows: By pre-adjusting the distance between the lower grinding disc 16 and the upper grinding disc 17, in specific operation, the hydraulic push rod 10 is activated. The output end of the hydraulic push rod 10 extends and retracts, driving the connecting plate 11 to move up and down. Since the connecting plate 11 is connected to the rotating sleeve 19 through the bearing, the rotating sleeve 19 will rise and fall synchronously with the connecting plate 11, thereby driving the upper grinding disc 17 fixed at the bottom of the rotating sleeve 19 to rise and fall, realizing the adjustment of the distance between the upper grinding disc 17 and the lower grinding disc 16. During this process, the first gear 20 outside the rotating sleeve 19 always maintains a meshing state with the second gear 22 on the transmission rod 21 to ensure that the subsequent power transmission is not affected.

[0039] After adjustment, the chemical raw materials to be ground are added into the device through the feed pipe 7 at the top of the top frame 5. The raw materials enter the rotating sleeve 19 through the feed pipe 7 and finally fall on the surface of the lower grinding disc 16. Grinding protrusions are provided on the grinding surfaces of the lower grinding disc 16 and the upper grinding disc 17 to enhance the grinding effect.

[0040] Subsequently, the second motor 12 is started, and the output end of the second motor 12 drives the transmission shaft 13 to rotate. The transmission shaft 13 rotates stably under the support of the first support frame 14, which in turn drives the lower grinding disc 16 fixed at the top of the transmission shaft 13 to rotate. At the same time, the first motor 6 is started, and the output end of the first motor 6 drives the transmission rod 21 to rotate. The transmission rod 21 drives the external second gear 22 to rotate. The second gear 22 meshes with the first gear 20, thereby driving the rotating sleeve 19 to rotate. The rotating sleeve 19 rotates stably under the cooperation of the second support frame 18 and the inner slip ring 23 (the inner slip ring 23 is slidably connected to the sliding groove 24 on the rotating sleeve 19, which does not affect the rotation of the rotating sleeve 19, but also provides support and limit). Finally, it drives the upper grinding disc 17 to rotate. It is worth noting that the upper grinding disc 17 rotates in the opposite direction to the lower grinding disc 16. This reverse rotation design can make the raw material subject to a stronger grinding force.

[0041] When the lower grinding disc 16 rotates, it generates centrifugal force, which causes the raw material falling on its surface to rotate and diffuse outward. As the gap between the lower grinding disc 16 and the upper grinding disc 17 gradually decreases from the center outward, the raw material will be subjected to a gradually increasing grinding force during the outward diffusion process. After sufficient grinding, the fine powder with the required particle size will pass through the gap between the grinding discs and fall into the bottom of the grinding tank 1. The baffle 15 fixedly installed on the inner wall of the grinding tank 1 can effectively prevent the powder from splashing upward, thus avoiding raw material waste and equipment contamination.

[0042] Finally, the powder that falls to the bottom of the grinding jar 1 is discharged through the discharge pipe 2 at the bottom, completing the entire grinding process;

[0043] Once a batch of raw materials has been ground, the cleaning assembly can be activated to clean the inside of the device. The compressor 8 on the top of the top frame 5 is started, and the high-pressure gas generated by the compressor 8 is transported through the air supply pipe 9 and sprayed out through multiple air holes 25 on the surface of the air supply pipe 9 to blow away the lower grinding disc 16, the upper grinding disc 17, and the inner wall of the grinding tank 1, cleaning away the remaining raw material debris so that the next batch of grinding can be carried out. Multiple support columns 4 fixed at the bottom of the grinding tank 1 provide stable support for the entire device, ensuring that the device remains stable during operation.

[0044] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
