Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a fine filtration component and a pharmaceutical grinder. Background Technique

[0002] A pharmaceutical grinder is a kind of grinding equipment specifically used in the pharmaceutical industry, designed to grind large-sized solid raw materials to the required size to meet the needs in the pharmaceutical process. This grinder usually has an enclosed storage chamber to ensure the safety and hygiene of drugs. Its main shaft speed is usually relatively high, which can reach 7000 revolutions per minute, and at the same time, the working noise is controlled below 85 decibels. The grinding fineness range of the pharmaceutical grinder is wide, ranging from 10 to 120 meshes, suitable for the grinding needs of western medicine and traditional Chinese medicine.

[0003] In a conventional drug grinding device, due to the relatively simple structure of its internal filtering structure, it is difficult to achieve multi-layer filtration. At the same time, the structure separated by screening after filtration cannot be refined and ground synchronously, and requires separate treatment by external equipment, making the processing efficiency relatively limited.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a fine filtration component and a pharmaceutical grinder are proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fine filtration component and a pharmaceutical grinder to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a fine filtration component and a pharmaceutical grinder, including a filtration tank and a filtration structure. A cover plate assembly is installed on the top of the filtration tank, and a transmission shaft is vertically installed inside the filtration tank. Moreover, four groups of rotating rollers are vertically arranged on the surface of the transmission shaft. The filtration structure is arranged directly below the rotating rollers. The filtration structure includes a filter plate, a bearing sleeve, a support frame, and a vibration motor. A bearing sleeve vertically penetrates through the middle of the filter plate, a support frame is installed at the bottom of the filter plate, and a vibration motor is installed at the bottom of the support frame.

[0007] Further, the filtration tank includes a tank body, connection piles, and guide grooves. Four groups of connection piles are annularly arranged on the upper end of the outer surface of the tank body, and four groups of guide grooves are vertically and equidistantly arranged on the inner wall surface of the tank body.

[0008] Further, the cover plate assembly includes a cover body, fixing piles, and fastening bolts. Four groups of fixing piles are annularly arranged on the edge of the cover body, and fastening bolts vertically penetrate through the middle of the fixing piles in a threaded manner.

[0009] Further, the rotating grinder includes a fixed sleeve, a grinding roller and a guide wheel. Three groups of grinding rollers are horizontally and annularly arranged on the side surface of the fixed sleeve, and a guide wheel is installed at one end of the grinding roller away from the fixed sleeve.

[0010] Further, four groups of filter plates are arranged at equal intervals from top to bottom and arranged in ascending order of mesh number, and the grinding roller is attached to the top surface of the filter plate. The surface structure of the guide wheel matches the inner surface structure of the guide groove.

[0011] Further, a servo motor is installed at the center of the top of the cover assembly, and a feeding port is arranged on one side of the servo motor.

[0012] Further, the bottom power output end of the servo motor is connected to the top end of the transmission shaft through a coupling, and the transmission shaft vertically penetrates the center of the rotating grinder and the filtering structure.

[0013] A pharmaceutical pulverizer is installed with the fine filtering component as described above.

[0014] The present utility model provides a fine filtering component and a pharmaceutical pulverizer, which have the following beneficial effects:

[0015] 1. In the present utility model, four groups of filtering structures are arranged at equal intervals in the vertical direction by using the transmission shaft inside the filter tank. Among them, the four groups of filter plates are arranged in ascending order of mesh number from small to large from top to bottom. By using this structure, the drugs put into the tank can be screened and filtered multiple times to ensure the quality of the final drug processing. And by installing a vibration motor at each of the four corners of the bottom of the cross-shaped support frame, the vibration generated by the operation of the vibration motor structure can effectively prevent the blockage of the holes on the surface of the filter plate while promoting the filtering efficiency, thereby ensuring the operation speed of the entire device.

[0016] 2. In the present utility model, by adopting a rotating grinder arranged in the same way as the filtering structure, since the rotating grinder is connected to the transmission shaft by a fixed sleeve, when the servo motor drives the transmission shaft to rotate vertically axially inside the filter tank, it will drive the four groups of connected rotating grinders to rotate synchronously. As the grinding roller rotates and contacts the structure on the top surface of the filter plate, the operation of crushing and grinding the drug can be realized. At the same time, with the operation of the vibration motor, it can be ensured as much as possible that there is no unnecessary blockage when the crushed drug is filtered by the filter plate, and thus the processing efficiency is ensured as much as possible while guaranteeing the quality. In addition, the guide groove opened on the inner wall surface of the tank, in cooperation with the use of the guide wheel, can ensure that the grinding roller rolls along the surface of the filter plate while ensuring sufficient rotational stability to prevent the structure from jumping due to crushing the drug.

[0022] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figures 1 to 4 shown, a fine filtration component and a pharmaceutical crusher include a filter tank 1 and a filtration structure 5. A cover plate assembly 2 is installed on the top of the filter tank 1, and a transmission shaft 3 is vertically installed inside the filter tank 1. Moreover, four groups of rotating grinders 4 are vertically arranged on the surface of the transmission shaft 3. The filtration structure 5 is arranged directly below the rotating grinders 4. The filtration structure 5 includes a filter plate 501, a bearing sleeve 502, a support frame 503, and a vibration motor 504. A bearing sleeve 502 vertically penetrates through the middle of the filter plate 501, and a support frame 503 is installed at the bottom of the filter plate 501. Moreover, a vibration motor 504 is installed at the bottom of the support frame 503. Four groups of filter plates 501 are arranged at equal intervals from top to bottom and arranged in ascending order of mesh number. And the grinding roller 402 is in contact with the top surface of the filter plate 501. The surface structure of the guide wheel 403 matches the inner surface structure of the guide groove 103. Among them, the four groups of filter plates 501 are arranged in ascending order of mesh number from top to bottom. By using this structure, the drugs put into the tank body 101 can be screened and filtered multiple times to ensure the quality of the final drug processing.

[0024] As shown Figures 1 to 4 in the figure, the filter tank 1 includes a tank body 101, connecting piles 102 and guide grooves 103. Four groups of connecting piles 102 are annularly arranged at the upper end of the outer surface of the tank body 101, and four groups of guide grooves 103 are vertically and equidistantly arranged on the inner wall surface of the tank body 101. The cover plate assembly 2 includes a cover body 201, fixing piles 202 and fastening bolts 203. Four groups of fixing piles 202 are annularly arranged at the edge of the cover body 201, and fastening bolts 203 vertically penetrate through the middle of the fixing piles 202 in a threaded manner. The rotating roller 4 includes a fixed sleeve 401, a grinding roller 402 and a guide wheel 403. Three groups of grinding rollers 402 are horizontally and annularly arranged on the side surface of the fixed sleeve 401, and a guide wheel 403 is installed at one end of the grinding roller 402 away from the fixed sleeve 401. A servo motor 6 is installed at the center of the top of the cover plate assembly 2, and a feeding port 7 is arranged on one side of the servo motor 6. The bottom power output end of the servo motor 6 is connected to the top end of the transmission shaft 3 through a coupling, and the transmission shaft 3 vertically penetrates through the centers of the rotating roller 4 and the filtering structure 5. When the servo motor 6 drives the transmission shaft 3 to rotate vertically along the axis inside the filter tank 1, it will drive four groups of connected rotating rollers 4 to rotate synchronously. As the grinding roller 402 rotates and contacts the structure on the top surface of the filter plate 501, the operation of crushing and grinding the medicine can be realized. At the same time, with the operation of the vibration motor 504, it can be ensured as much as possible that when the crushed medicine is filtered by the filter plate 501, unnecessary blockage does not occur.

[0025] A pharmaceutical pulverizer is installed with the fine filtering component as described above. Four groups of filter plates 501 with different filtering meshes are vertically and equidistantly arranged on the surface of the transmission shaft 3. At the same time, with the vibration motor 504 at the bottom of the support frame 503, the medicine put into the filter tank 1 can be quickly filtered in multiple layers. At the same time, with the use of the rotating roller 4, driven by the servo motor 6, the rotating roller 4 will effectively roll the medicine fragments staying on the top surface of the filter plate 501, which can break the medicine and assist the filter plate 501 to carry out fine filtering, thus ensuring the quality of medicine processing.

[0026] In summary, as Figures 1 to 4 shown in the figure, when using this fine filtering component and the pharmaceutical pulverizer, first, the crushed medicine materials are put into the filter tank 1 through the feeding port 7 installed at the top of the cover plate assembly 2, and then the servo motor 6 and the vibration motor 504 at the bottom of the support frame 503 are started simultaneously;

[0027] With the operation of the servo motor 6, the transmission shaft 3 connected to its power output end will start to rotate axially in the vertical direction. Then, the rotating roller 4 connected to the transmission shaft 3 through the fixed sleeve 401 will rotate synchronously. At this time, the grinding roller 402 will roll along the surface of the filter plate 501 with the fixed sleeve 401 as the center. At the same time, the guide wheel 403 installed at one end will roll synchronously along the guide groove 103 opened on the inner wall of the tank body 101 to ensure the smooth rotation of the entire rotating roller 4;

[0028] Under the rolling of the grinding roller 402 and the operation of the vibration motor 504, the further crushed medicine will be gradually refined and filtered from the surface of the filter plate 501, thus achieving good processing. When it is necessary to clean the inside of the filter tank 1, only need to screw out the fastening bolt 203 from the inside of the connecting pile 102 and the fixed pile 202, and then the tank body 101 and the cover body 201 can be quickly separated structurally.
