These raw materials generally need to be ground before they can be put into subsequent processing.

[0003] Existing grinding devices generally use a grinding wheel and a grinding sleeve to cooperate with each other to achieve the effect of grinding chemical raw materials. However, after use, it is inevitable that some raw materials will adhere to the surface of the grinding piece. Because the gap between the two is small, the cleaning process of the two becomes more troublesome, and there is room for improvement. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a grinding device for processing organic chemical raw materials includes a mounting box 1, which is characterized in that: a lifting assembly 3 is installed on the outside of the mounting box 1, and the lifting assembly 3 includes two extension plates 301 fixedly connected to the bottom of the outer walls on both sides of the mounting box 1, one of the extension plates 301 has a top outer wall rotatably connected to a screw rod 302, the screw rod 302 has an external threaded connection to a mounting frame 304, one end of the mounting frame 304 is slidably inserted with a limit rod 305, one end of the limit rod 305 is fixedly connected to the top outer wall of the other extension plate 301, a motor 306 is fixedly installed on the bottom outer wall of one of the extension plates 301, and the output end of the motor 306 and the bottom end of the screw rod 302 are coaxially fixed.

[0024] The inner walls on both sides of the mounting frame 304 are respectively in contact with the outer walls on both sides of the mounting box 1 , and the box wall of the mounting box 1 can limit the mounting frame 304 , thereby ensuring that the state of the mounting frame 304 is more stable.

[0025] By starting the motor 306 to drive the screw rod 302 to rotate, the mounting frame 304 will be driven to move upward under the cooperation of the screw rod 302 and the limit rod 305, and then the grinding assembly 4 installed in the middle of the mounting frame 304 will also be driven to move synchronously, and the grinding wheel 402 will also be separated from the internal space of the grinding sleeve 2. At this time, cleaning will be easier, and the gap between the grinding wheel 402 and the bottom opening of the grinding sleeve 2 can be adjusted by controlling the position of the mounting frame 304 to ensure that the device can process raw material particles of different sizes.

[0026] like Figure 3 and Figure 4 As shown, a grinding assembly 4 is installed inside the mounting frame 304, and the grinding assembly 4 includes a mounting ring 401 that is rotatably connected to the center of the mounting frame 304, and a plurality of connecting rods distributed at equal distances are arranged at the bottom of the mounting ring 401, and a same grinding wheel 402 is fixedly connected to one end of the bottom of the plurality of connecting rods.

[0027] A gear ring 403 is coaxially fixed to the top outer wall of the mounting ring 401 . A second motor 405 is fixedly mounted on the top outer wall of the mounting ring 401 . A gear 404 is coaxially fixed to the output end of the second motor 405 . The gear 404 meshes with the gear ring 403 .

[0028] The transmission ratio between the gear ring 403 and the gear 404 is much smaller than 1. The gear 404 rotates one circle to drive the gear ring 403 to rotate one circle, ensuring that the stress on the motor 2 405 is smaller when it is working.

[0029] Start the second motor 405, which drives the gear 404 to rotate. The gear 404 can drive the mounting ring 401 to rotate in the middle of the mounting frame 304 through the gear ring 403 meshing with it. The mounting frame 304 drives the grinding wheel 402 to rotate in the middle of the grinding sleeve 2. Since the connection area between the mounting frame 304 and the grinding wheel 402 is large enough, the state of the grinding wheel 402 can be guaranteed to be more stable. With the cooperation of the two, the grinding work can be started, and the raw materials will be gradually ground into small particles.

[0030] like Figure 1 and Figure 2 As shown, a grinding sleeve 2 matched with the grinding wheel 402 is fixedly installed inside the installation box 1, and the grinding wheel 402 can be located in the middle of the grinding sleeve 2.

[0031] like Figure 1 and Figure 3As shown, the thread lead angle of the thread groove on the circumferential outer wall of the screw rod 302 is smaller than the equivalent friction angle, so that the screw rod 302 has a self-locking property, ensuring that the position of the mounting bracket 304 will not change arbitrarily after being adjusted.

[0032] The utility model provides a grinding device for processing organic chemical raw materials, and the specific working principle is as follows:

[0033] When the device is working, the raw material to be processed is introduced into the gap between the grinding sleeve 2 and the grinding wheel 402, and then the motor 2 405 is started. The motor 2 405 drives the gear 404 to rotate. The gear 404 can drive the mounting ring 401 to rotate in the middle of the mounting frame 304 through the gear ring 403 meshing therewith, and the mounting frame 304 drives the grinding wheel 402 to rotate in the middle of the grinding sleeve 2. Since the connection area between the mounting frame 304 and the grinding wheel 402 is large enough, the state of the grinding wheel 402 can be ensured to be more stable. With the cooperation of the two, the grinding work can be started, and the raw material will be gradually ground into small particles to complete the processing. After work, if the grinding sleeve 2 and the grinding wheel 402 need to be cleaned, it is only necessary to start the motor 306 to drive the screw rod 302 to rotate. Under the drive of the screw rod 302 and the cooperation of the limit rod 305, the mounting frame 304 will be driven to move upward, and then the grinding assembly 4 installed in the middle of the mounting frame 304 will also be driven to move synchronously, and the grinding wheel 402 will also be separated from the internal space of the grinding sleeve 2. At this time, cleaning will be easier, and the gap between the grinding wheel 402 and the bottom opening of the grinding sleeve 2 can be adjusted by controlling the position of the mounting frame 304 to ensure that the device can process raw material particles of different sizes.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
