For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Please see attached Figure 1 -Attached Figure 5 The endocrine drug pulverizing device comprises a bracket 1, a pulverizing barrel 3 is fixedly installed on the top of the bracket 1, a filter plate 9 is fixedly installed on the bottom of the pulverizing barrel 3, a hollow tube 11 is rotatably installed in the middle of the top of the filter plate 9, a pulverizing knife 10 and a stirring frame 12 with a mouth-shaped structure are fixedly sleeved on the surface of the hollow tube 11, the stirring frame 12 has a hollow structure inside, a plurality of third air holes 17 are opened on the two opposite side surfaces of the stirring frame 12 close to the pulverizing knife 10, two first air holes 14 connected with the inside of the stirring frame 12 are opened on the surface of the hollow tube 11, the pulverizing barrel 3 comprises a base 301 and a barrel body 302, a discharge trough 303 with a funnel structure is opened on the top of the base 301, the surface of the discharge trough 303 is coated with a polytetrafluoroethylene coating, and a cover plate 5 is detachably and fixedly installed on the top of the barrel body 302.

[0024] When in use, by providing the hollow tube 11 and the stirring frame 12, the compressed air can enter the hollow tube 11 to discharge the crushed medicine powder from the bottom of the crushing barrel 3, and enter the cyclone separator 2 through the conveying pipe 4 for separation. A valve is provided at the bottom of the cyclone separator 2, so that the powder can be temporarily stored at the bottom of the cyclone separator 2, and taken out uniformly after the crushing operation is completed. After the crushing is completed, the compressed air can pass through the hollow structure of the stirring frame 12 and the third air hole 17 opened in the stirring frame 12, and blow on the outer surface of the crushing knife 10 to clean the surface. It is not necessary to disassemble the crushing knife 10 for cleaning, thereby improving the working efficiency of equipment cleaning.

[0025] When manufacturing the barrel body 302, a transparent viewing window can be opened on its surface to facilitate observation of the crushing situation inside the crushing barrel 3. A discharge trough 303 is opened so that the crushed powder can quickly enter the conveying pipe 4 after passing through the filter plate 9. The polytetrafluoroethylene coating has good chemical resistance, non-stickiness, high temperature resistance and biological inertness. It will not react with the medicine and can make the powder discharge smoothly, thereby improving the practicality of the equipment.

[0026] In this embodiment, a cyclone separator 2 is fixedly installed on one side of the bracket 1, a discharge port is provided at the bottom of the crushing barrel 3, a conveying pipe 4 is fixedly installed in the discharge port, the other end of the conveying pipe 4 is connected to the feed end of the cyclone separator 2, a feed port for adding materials is provided on the top of the cover plate 5, a sealing plug is connected to the inner thread of the feed port, a through hole compatible with the hollow tube 11 is provided in the middle of the top of the cover plate 5, a servo motor 7 is fixedly installed on one side of the top of the cover plate 5, a belt 8 is sleeved between the output end of the servo motor 7 and the hollow tube 11, the hollow tube 11 is rotatably installed in the through hole provided in the cover plate 5, an air compressor 6 is fixedly installed on the top of the hollow tube 11, and the air outlet end of the air compressor 6 is connected to the inside of the hollow tube 11.

[0027] When in use, unscrew the sealing plug on the top of the cover plate 5, and the medicine to be crushed can be added through the feed port; when crushing, start the servo motor 7 to drive the hollow tube 11 to rotate through the belt 8, and the hollow tube 11 simultaneously drives the crushing knife 10 and the stirring frame 12 to rotate, and at the same time start the air compressor 6 to pump compressed air into the hollow tube 11. The air compressor 6 adopts a small screw compressor. Most of the compressed air passes through the hollow tube 11 and enters the bottom of the filter plate 9, bringing the powder in the discharge trough 303 into the conveying pipeline 4, and then enters the cyclone separator 2 for separation. Another part of the compressed air will enter the inside of the stirring frame 12 from the first air hole 14, and then be blown out from the third air hole 17, blowing up the crushed powder in the crushing barrel 3 and then evenly passing through the filter plate 9 into the discharge trough 303, avoiding powder accumulation, and at the same time avoiding the drug particles from blocking the various air holes on the surface of the stirring frame 12, thereby improving the working efficiency of the equipment crushing.

[0028] In this embodiment, the first scraper strips 13 are fixedly installed on both sides of the stirring frame 12 near the inner wall of the barrel body 302, and one side of each first scraper strip 13 is against the inner wall of the barrel body 302. The second scraper strips 15 are fixedly installed on the two opposite sides of the stirring frame 12 near the bottom, and the bottom of each second scraper strip 15 is against the top of the filter plate 9. Each of the first scraper strips 13 and the second scraper strip 15 is provided with an inclined surface, and a plurality of second air holes 16 are provided on the two opposite sides of the stirring frame 12, and each second air hole 16 faces the inclined surface of the corresponding first scraper strip 13.

[0029] When in use, the first scraper 13 and the second scraper 15 rotate with the stirring frame 12 to clean the inner wall of the barrel 302 and the surface of the filter plate 9 respectively, so as to prevent the powder from sticking together, thereby improving the recovery rate of the equipment for the medicinal powder and avoiding waste of resources. A second air hole 16 is provided, and part of the compressed air is blown out from it to clean the powder adhering to the first scraper 13 and the inner wall of the barrel 302 in time, thereby improving the cleaning efficiency of the first scraper 13. The apertures of the second air hole 16 and the third air hole 17 are much smaller than the outer diameter of the medicinal raw material.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
