Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine chemistry technology, specifically to an impurity removal device for preparing traditional Chinese medicine chemical reference standards. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to substances used for the prevention, treatment, and diagnosis of diseases, as well as for rehabilitation and health maintenance, under the guidance of TCM theory. TCM mainly comes from natural medicines and their processed products, including plant-based medicines, animal-based medicines, mineral-based medicines, and some chemical and biological products. Impurity removal devices are required during the preparation process.

[0003] Existing technologies, such as CN215030077U, describe an impurity removal device for preparing chemical reference standards of traditional Chinese medicine. When a motor drives a rotating cavity to rotate at high speed, the rotating cavity drives a support column to rotate. The support column rotates inside the working box through a rotatable connection with the working box, which also serves to support the rotating cavity.

[0004] However, this device still has some shortcomings in its use: 1. Simply using a rotating chamber for stirring reduces work efficiency. Since the rotating chamber can only achieve stirring in one direction, the separation process of Chinese medicine raw materials and impurities is relatively slow and cannot quickly and fully separate impurities from the Chinese medicine raw materials.

[0005] 2. The top cover is connected to the box body by bolts, which makes it inconvenient to open and close quickly. In actual operation, it is quite cumbersome and consumes a lot of time and manpower. Utility Model Content

[0006] The purpose of this invention is to provide an impurity removal device for preparing chemical reference standards of traditional Chinese medicine, so as to solve the problem mentioned in the background art that the efficiency is reduced by simply stirring through a rotating cavity.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An impurity removal device for preparing chemical reference standards of traditional Chinese medicine includes a protective box, inside which a preparation component is arranged, and on the top of the protective box an auxiliary component is arranged.

The preparation component 2 includes a preparation cylinder 210 rotatably connected inside the protective box 1, an annular rack 206 fixedly connected to the outer surface of the preparation cylinder 210, a filter screen frame 205 snapped into the inside of the preparation cylinder 210, a positioning plate 207 fixedly connected to the inner wall of the protective box 1, a second motor 208 mounted on the top of the positioning plate 207, a drive wheel 209 fixedly connected to the output end of the second motor 208, the drive wheel 209 meshing with the annular rack 206, an installation cover 303 on the top of the protective box 1, a telescopic cylinder 204 mounted on the top of the installation cover 303, an installation plate 203 fixedly connected to the top of the telescopic cylinder 204, a first motor 201 mounted on the bottom of the installation plate 203, and a stirring rack 202 fixedly connected to the output end of the first motor 201.

[0021] The telescopic cylinder 204 has one end abutting against the mounting plate 203 and the other end abutting against the mounting cover 303. The telescopic cylinder 204 extends and retracts, causing the mounting plate 203 and the mounting cover 303 to move away from or closer to each other, thereby driving the stirring frame 202 to rise or fall relative to the mounting cover 303, that is, to move up and down inside the preparation cylinder 210. The stirring frame 202 is driven to rotate by the first motor 201, which stirs the raw materials up and down. The drive wheel 209 meshes with the ring rack 206, thereby driving the preparation cylinder 210 to rotate inside the protective box 1, so that the raw materials are fully tumbled inside the preparation cylinder 210.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a sealing groove 301 is opened at the top of the protective box 1. A sealing plate 302 is fixedly connected to the bottom of the mounting cover 303. An elastic plate 304 is fixedly connected to the bottom of the sealing plate 302. The sealing plate 302 is used to insert into the sealing groove 301 and abut against the sealing groove 301. A positioning groove 305 is opened on the side of the sealing plate 302. The elastic plate 304 is made of rubber. A fixing rod 306 is provided on the side of the protective box 1. The fixing rod 306 passes through the protective box 1 and extends into the positioning groove 305. The fixing rod 306 is inserted into the protective box 1. A through hole is opened at the top of the mounting cover 303. The stirring rack 202 passes through the through hole and extends into the preparation cylinder 210. A telescopic rod 6 is fixedly connected to the top of the cover 303. The telescopic rod 6 passes through the mounting plate 203 and is slidably connected to the mounting plate 203. A protective plate 7 is fixedly connected to the top of the telescopic rod 6. The protective plate 7 is located on the top of the mounting plate 203. A feed pipe 8 is fixedly connected to the top of the cover 303. The feed pipe 8 is connected to the preparation cylinder 210. A controller 4 is provided on the side of the protective box 1. The first motor 201, the second motor 208 and the telescopic cylinder 204 are electrically connected to the controller 4 respectively. A discharge pipe 9 is fixedly connected to the bottom of the preparation cylinder 210. The discharge pipe 9 passes through the protective box 1 and extends to the bottom of the protective box 1. A base 5 is fixedly connected to the bottom of the protective box 1.

[0023] When it is necessary to open the mounting cover 303, the fixing rod 306 can be pulled out directly, and the elastic plate 304 will lift the sealing plate 302, which will facilitate the quick installation and removal of the mounting cover 303.

[0024] The working process of this utility model is as follows: When using the impurity removal device designed in this scheme for preparing traditional Chinese medicine chemical reference standards, first check whether the device is working properly. Connect the external power supply to the electrical structure of the device. The preparation cylinder 210 is rotatably installed in the protective box 1. The raw material of the traditional Chinese medicine chemical reference standard that needs to be impurity removed is slowly poured into the preparation cylinder 210 through the feed pipe 8. At this time, the telescopic cylinder 204 and the first motor 201 are started. The telescopic cylinder 204 drives the driven stirring frame 202 to move up and down in the preparation cylinder 210 to stir the raw material. Larger particles of impurities are trapped on the activated carbon filter screen 205. Then the second motor 201 is started. Motor 208 drives drive wheel 209 to rotate. Drive wheel 209 meshes with ring rack 206, thereby driving preparation cylinder 210 to rotate inside protective box 1, so that raw materials can be fully tumbled inside preparation cylinder 210, further promoting the separation of impurities and effective components. After the impurity removal work has been carried out for a period of time, feed pipe 9 is opened to discharge the Chinese herbal chemical reference raw material after impurity removal treatment. During the whole working process, controller 4 can control first motor 201, telescopic cylinder 204 and second motor 208. After pulling out fixing rod 306, it is easy to open mounting cover 303 to facilitate cleaning inside preparation cylinder 210.

[0025] The first motor 201, telescopic cylinder 204, and second motor 208 used in this utility model are all existing known electrical devices, and can be directly purchased and used on the market. Their structure, circuit and control principle are all existing known technologies. Therefore, the structure, circuit and control principle of the first motor 201, telescopic cylinder 204 and second motor 208 will not be described in detail here.
