Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical grinding, and in particular to a pharmaceutical testing grinding machine. Background Technology

[0002] Drug testing refers to the comprehensive evaluation of drug quality based on various indicators stipulated in drug quality standards, using specific testing methods and techniques. Its purpose is to ensure the quality and safety of drugs, prevent substandard drugs from entering the market, and ensure the effectiveness and safety of drugs. Grinding is a common processing method in drug testing. The purpose of grinding is to make the drug components more evenly dispersed in the solvent, thereby improving the accuracy and reliability of the test. Through grinding, the drug particles can be refined, making them easier to dissolve and extract, thus allowing for more accurate determination of their components and properties.

[0003] A search revealed that Chinese Patent Announcement No. CN221847361U discloses a pharmaceutical testing grinder. By setting up a cleaning structure and subdividing the cleaning structure into a scraping unit and a sweeping unit, the residual powder on the top and bottom of the working end of the grinding structure can be cleaned during use. This avoids the situation where the powder is taken out along with the grinding material, resulting in contamination and waste.

[0004] In the above technical solution, a cleaning structure is set up to clean the powder after the medicine is ground, so as to avoid waste. However, the grinding cylinder lacks a cooling function, and a lot of heat is generated during the grinding process. Many drug components are sensitive to high temperature. The grinding process needs to be paused and the heat needs to be dissipated before grinding can continue, which will reduce the grinding efficiency. If grinding continues, the heat will damage the components in the medicine, resulting in a decrease in the accuracy of subsequent testing. Therefore, a drug testing grinding machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a pharmaceutical testing grinder, which aims to improve the problem that existing pharmaceutical testing grinders lack a cooling function during grinding, resulting in the pharmaceutical components being affected and reducing the accuracy of subsequent testing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a pharmaceutical testing grinder, comprising a base 1, a support 2 fixedly connected to the top of the base 1, a grinding cylinder 3 fixedly connected to the top of the base 1, a hydraulic cylinder 4 fixedly connected to the top of the support 2, a lifting plate 5 fixedly connected to the output end of the hydraulic cylinder 4, a sliding rod 6 fixedly connected to the inner wall of the lifting plate 5, two sets of sliding rods 6 arranged symmetrically about the central axis of the hydraulic cylinder 4, the outer wall of the sliding rod 6 slidingly connected to the inner wall of the support 2, a sealing cover 7 fixedly connected to the bottom end of the sliding rod 6, a motor 8 fixedly connected to the top of the sealing cover 7, a drive wheel 9 fixedly connected to the output end of the motor 8 via a shaft, and a rotating wheel 9 rotatably connected to the inner wall of the sealing cover 7. A driven wheel 10 is fixedly connected to the outer wall of a shaft 11, and a driving wheel 9 meshes with the driven wheel 10. A grinding blade 12 is fixedly connected to the outer wall of the shaft 11. Several sets of grinding blades 12 are provided, and the size of the several sets of grinding blades 12 increases progressively from top to bottom. The grinding blades 12 that increase in size from top to bottom form an inverted conical structure, which inhibits the powder from splashing upward under the action of centrifugal force, reduces sample loss, and prevents insufficiently ground particles from accumulating at the bottom of the container. The smaller grinding blade 12 at the top generates less heat when cutting at high speed at the top due to its small contact area. The larger grinding blade 12 at the bottom completes the final grinding in the low-speed zone at the bottom, avoiding concentrated frictional heat generation and protecting the heat-sensitive components in the medicine.

[0033] Reference Figures 2-4A spiral cooling pipe 13 is fixedly connected to the outer wall of the grinding cylinder 3. The outer wall of the spiral cooling pipe 13 fits against the outer wall of the grinding cylinder 3, enclosing the grinding cylinder 3. The cooling source is transferred to the grinding cylinder 3 through the coolant inside. The spiral arrangement increases the contact area between the coolant and the grinding cylinder 3. A circulation pump 16 is fixedly connected to the end of the spiral cooling pipe 13 via a pipe. The bottom of the circulation pump 16 is fixedly connected to the top of the liquid storage tank 15. The circulation pump 16 is also fixedly connected to the liquid storage tank 15 via a pipe. The circulation pump 16 can draw out the coolant inside the liquid storage tank 15 and pass it through the storage tank 15. The coolant is transported to the spiral refrigeration tube 13 through a pipeline, or the coolant in the spiral refrigeration tube 13 can be extracted and transported to the storage tank 15. The storage tank 15 is used to store the coolant. The bottom of the storage tank 15 is fixedly connected to the top of the base 1. A cooler 17 is fixedly connected to the outer wall of the storage tank 15. The cooler 17 cools the coolant inside the storage tank 15 to realize the recycling of the coolant. A heat insulation cover 14 is fixedly connected to the outer wall of the grinding cylinder 3. The heat insulation cover 14 relatively isolates the spiral refrigeration tube 13 from the external environment to prevent heat loss. The heat insulation cover 14 is fitted on the outer wall of the spiral refrigeration tube 13.

[0034] Reference Figures 3-5 A rotating collar 20 is rotatably connected to the top of the rotating shaft 11. A branch pipe 18 is fixedly connected to the inner wall of the rotating collar 20. A portion of the branch pipe 18 is retractable to ensure stable connection when the sealing cover 7 is raised or lowered. A solenoid valve 19 is fixedly connected to the end of the branch pipe 18. The solenoid valve 19 is connected to the spiral refrigeration pipe 13 and the circulation pump 16 via a pipe. The pipe of the solenoid valve 19 is referred to as the small pipe, and the pipe of the spiral refrigeration pipe 13 and the circulation pump 16 is referred to as the large pipe. The small pipe extends through the large pipe. Inside the channel, coolant can be drained out, and the draining is controlled by solenoid valve 19. A positioning frame 21 is fixedly connected to the top of the sealing cover 7. The inner wall of the positioning frame 21 is fixedly connected to the outer wall of the branch pipe 18. The positioning frame 21 provides support and positioning force for the branch pipe 18. The end of the branch pipe 18 passes through the rotating collar 20. The inner wall of the rotating shaft 11 is provided with a spiral heat dissipation groove 22. The branch pipe 18 passes through the rotating collar 20 and is embedded in the cavity at the top of the rotating shaft 11, which can transmit coolant into the spiral heat dissipation groove 22 through the cavity.

[0035] Working principle: The circulating pump 16 first extracts the coolant and delivers it to the spiral cooling pipe 13 to pre-cool the grinding cylinder 3. At the same time, the solenoid valve 19 is in the open state, and the coolant can be transmitted through the small pipe to the branch pipe 18, and finally enter the spiral heat dissipation groove 22. The medicine to be ground is put into the grinding cylinder 3. The hydraulic cylinder 4 drives the lifting plate 5 to descend. At this time, the two sets of sliding rods 6 slide down until the sealing cover 7 closes the opening of the grinding cylinder 3. The motor 8 starts and drives the drive wheel 9 to rotate, so that the driven wheel 10 drives the rotating shaft 11 to rotate. Multiple sets of grinding blades 12 grind the medicine, so that the grinding environment is kept in a relatively cool environment during the grinding process. After grinding for a period of time, the circulating pump 16 extracts the coolant from the spiral heat dissipation groove 22 and the spiral cooling pipe 13 and transmits it to the storage tank 15 to neutralize it with the coolant at a lower temperature. Then, the circulating pump 16 transmits it back to the spiral heat dissipation groove 22 and the spiral cooling pipe 13 to avoid the risk of drug denaturation or failure due to frictional heat during the grinding process.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
