[0002] The patent number CN215088663U discloses a classification centrifuge for pharmaceutical use. The structure of the utility model is reasonably designed, avoiding manual operation, improving the classification quality and working efficiency.

[0003] However, for the above-mentioned existing classification centrifuge for pharmaceutical use, firstly, during use, it is fixed with a support column and a pressure spring installed above the base and a fixed frame to prevent the medicine from shaking during centrifugation. The medicine raw material is put into the centrifugal wire mesh frame from the feed inlet. By starting the first motor to drive the driving gear and the transmission gear to rotate, the transmission gear drives the rotating shaft, the centrifugal wire mesh frame, the cleaning plate and the pulley to move centrifugally, or by starting the second motor to drive the driving wheel and the driven wheel to rotate, the driven wheel drives the rotating shaft, the centrifugal wire mesh frame, the cleaning plate and the pulley to move centrifugally, so as to classify the medicine raw material and convey it onto the screening net. Since the device lacks a stirring structure for the material, it is difficult to break up the agglomerated raw materials for classification, resulting in poor classification effect.

In addition, it should be noted that this specification describes many features. Although some features can be combined together to show possible system designs, these features can also be used in other combinations not specifically described. Therefore, unless otherwise stated, the described combination is not intended to be limiting.

[0023] The principle and structure of the present utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0024] Reference Figure 1-6 , a centrifugal classifier for boric acid, comprising a protective box 1, a partition board 8 fixedly connected inside the protective box 1, a grading tank 7 slidably connected inside the partition board 8, a limit ring 15 fixedly connected to the inner wall of the protective box 1, the inner wall of the grading tank 7 being clamped on the surface of the limit ring 15, a feed pipe 9 fixedly connected to the back of the protective box 1, a rotating shaft 13 rotatably connected inside the protective box 1, a centrifugal plate 14 fixedly connected to the surface of the rotating shaft 13, the side of the centrifugal plate 14 being slidably connected and in contact with the inner wall of the grading tank 7, a spiral blade 12 fixedly connected to the surface of the rotating shaft 13, the side of the spiral blade 12 being rotatably connected and in contact with the inner wall of the feed pipe 9, a threaded hole 2 opened on the front of the protective box 1, and a cover plate 3 threadedly connected inside the threaded hole 2.

[0025] By setting the cover plate 3, when the cover plate 3 is tightened in the threaded hole 2, the cover plate 3 will abut against the front of the classification tank 7, preventing the classification tank 7 from shaking during operation.

[0026] Furthermore, a feed hopper 11 is fixedly connected to the surface of the feed pipe 9, and the lower end of the feed hopper 11 is communicated with the inside of the feed pipe 9.

[0027] By setting the feed hopper 11, the staff can add materials through the feed hopper 11.

[0028] Furthermore, a servo motor 10 is fixedly connected to the back of the feed pipe 9, and the output end of the servo motor 10 penetrates through the inner wall of the feed pipe 9 and is fixedly connected to one end of a rotating shaft 13.

[0029] By setting the servo motor 10, the servo motor 10 can drive the centrifugal plate 14 to rotate through the rotating shaft 13.

[0030] Furthermore, a first material collection box 5 is slidably connected inside the protection box 1, and a second material collection box 6 is slidably connected inside the protection box 1.

[0031] Furthermore, a handle 4 is fixedly connected to the front of the cover plate 3, and the back of the cover plate 3 abuts against the front of the classification tank 7.

[0032] By setting the handle 4, the staff can drive the cover plate 3 to rotate through the handle 4.

[0033] Furthermore, the shape of the classification tank 7 matches the shape of the inner wall of the partition plate 8, and one end of the feed pipe 9 is communicated with the inside of the protection box 1.

[0034] The working principle of the present utility model: First, the staff inserts the classification tank 7 into the partition plate 8 and makes the classification tank 7 stuck on the limiting ring 15. Then, the staff screws the cover plate 3 tightly into the threaded hole 2, so that the cover plate 3 abuts against the front of the classification tank 7, ensuring the stability of the classification tank 7 during operation. Then, the staff starts the servo motor 10 to drive the rotating shaft 13 to rotate clockwise, and the rotating shaft 13 drives the spiral blade 12 and the centrifugal plate 14 to rotate clockwise. At this time, the staff can add boric acid raw materials into the feed pipe 9 through the feed hopper 11. Under the rotation of the spiral blade 12, the boric acid raw materials can be conveyed into the classification tank 7, and the boric acid raw materials are dispersed by the centrifugal plate 14 and scattered in the classification tank 7. The boric acid raw materials that can pass through the classification tank 7 fall into the first material collection box 5 for storage, and the boric acid raw materials that cannot pass through the classification tank 7 fall into the second material collection box 6 for storage;

[0035] Compared with the prior art, the raw materials that cannot pass through the classification tank 7 continue to move forward and fall into the second material collection box 6 for storage, which can improve the classification effect of the device.

[0036] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
