Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical research equipment, and particularly to a medicine washing device for pharmaceutical research. Background Art

[0002] Pharmaceutical research is an important part of medical science, mainly studying scientific issues such as the properties, preparation, mechanism of action, quality control of drugs, and their interaction with the body. It covers multiple disciplinary directions such as medicinal chemistry, pharmaceutics, pharmaceutical analysis, pharmacology, and clinical pharmacy. In the process of pharmaceutical research and production, the cleaning of medicinal materials is a key link to ensure the effectiveness and safety of drugs.

[0003] With the progress of technology and the development of automation technology, the pharmaceutical research community has begun to explore more efficient and automated medicinal material cleaning devices to improve the cleaning efficiency and utilization rate of medicinal materials. However, there are still some problems with existing automated medicinal material cleaning devices. For example, according to the "Medicine Washing Device for Chinese Medicine Raw Material Processing" provided by the Chinese Patent Authorization Publication No. CN221288858U, by setting a stirring structure and controlling the operation of the second motor, the output end of the second motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring plate to rotate through the ring sleeve, achieving a more thorough cleaning effect of Chinese medicine. By setting a limiting structure, it achieves the effect of facilitating the unloading of Chinese medicine, reducing labor costs and having higher efficiency.

[0004] The above patent uses a single stirring method to clean medicinal materials, that is, using centrifugal force to drive the water liquid to clean the medicinal materials. However, this cleaning method is relatively single, and the cleaning effect is not ideal. Stirring cleaning can only clean the floating dust on the surface of the medicinal materials, and it is difficult to completely remove the adsorbed stains on the surface of the medicinal materials. Moreover, the cleaning devices using spraying and rolling on the market are also difficult to clean thoroughly.

[0005] To solve the above problems, a high-efficiency medicinal material cleaning device is urgently needed. Such a device should be able to effectively utilize the power of water flow and the action of mechanical stirring to effectively remove the stains and dust on the surface of the medicinal materials.

Connecting shafts are rotatably connected to both side ends of the power structure, and cleaning soft brushes are evenly fixedly installed on the outer surface of the connecting shafts.

[0013] Further, the power structure includes a power box fixedly connected to the connecting plate.

DETAILED DESCRIPTION

[0029] Embodiment 1, by Figure 1-7Provided is a medicinal herb washing device for pharmaceutical research, including an outer machine chamber 1 supported by support feet 11. One side of the bottom of the outer machine chamber 1 is fixedly communicated with a discharge pipe 12, and the discharge pipe 12 is connected to an external drain pipe. Inside the outer machine chamber 1, a cleaning drum 5 is connected through a bearing. At the open end of the cleaning drum 5 on the side of the outer machine chamber 1, a connecting auxiliary chamber 2 is fixed to cover the opening of the cleaning drum 5. The cleaning drum 5 is rotatably connected to the connecting auxiliary chamber 2. A gear ring 51 is fixed to the outside of the other end of the cleaning drum 5. Above the connecting auxiliary chamber 2, a feeding bin 3 is provided. A conveying pipe is fixed to the bottom of the feeding bin 3. The conveying pipe obliquely penetrates the connecting auxiliary chamber 2 and enters the cleaning drum 5. And a material scattering structure 9 is installed at the transmission position of the conveying pipe at the opening of the cleaning drum 5. A discharge port 21 is opened at the lower part of the connecting auxiliary chamber 2, and a sealing cover is embedded and installed in the discharge port 21 for sealing. A plurality of filter holes 52 are evenly opened on the surface of the cleaning drum 5, and a plurality of inclined material plates 53 are spirally installed inside the cleaning drum 5. In the middle of the cleaning drum 5, a driving cleaning structure 7 is connected through a bearing. One end of the driving cleaning structure 7 penetrates through the cleaning drum 5 and the outer machine chamber 1 and extends out and is connected to a connecting frame 8 in a transmission manner. The other end of the driving cleaning structure 7 is rotatably connected to the connecting auxiliary chamber 2 and is in transmission connection with the material scattering structure 9. At the lower part of the side of the outer machine chamber 1 away from the connecting auxiliary chamber 2, a support frame 4 is fixed. The connecting frame 8 is fixedly installed on the support frame 4, and a driving structure is also fixedly installed on the support frame 4 and is in transmission connection with the cleaning drum 5 and the driving cleaning structure 7.

[0030] Specifically, it is controlled to work through an external control electric box. During work, the driving structure drives the cleaning drum 5 to slowly rotate clockwise inside the outer machine chamber 1, and at the same time drives the driving cleaning structure 7 to rotate counterclockwise quickly, and drives the material scattering structure 9 to transmit and scatter materials. The experimenter pours the medicinal materials into the feeding bin 3, and the medicinal materials slide into the rotating cleaning drum 5 through the inclined conveying pipe. The plurality of inclined material plates 53 arranged spirally in the cleaning drum 5 convey and scatter the medicinal materials inside the cleaning drum 5. The driving cleaning structure 7 frictionally cleans the internal medicinal materials. The sewage generated by the cleaning is filtered through the plurality of filter holes 52 and enters the bottom of the outer machine chamber 1, and the sewage is discharged through the discharge pipe 12. After the cleaning is completed, the sealing cover of the discharge port 21 is opened, and then the reduction motor 6 is controlled to turn over, driving the cleaning drum 5 to rotate counterclockwise. The rotating cleaning drum 5 drives the cleaned medicinal materials to move to the discharge port 21 for discharge with the assistance of the plurality of inclined material plates 53 arranged spirally.

[0031] In this embodiment, the driving structure includes a reduction motor 6 fixed on the support frame 4. A large pulley 61 and a driving gear 62 are fixedly connected to the output shaft of the reduction motor 6. The large pulley 61 is sleeved with a transmission belt 63 and is in transmission connection with the driving cleaning structure 7. The driving gear 62 is meshed with the gear ring 51.

[0032] Specifically, the reduction motor 6 drives the large pulley 61 and the drive gear 62 through the output shaft. Among them, the drive gear 62 meshes with the gear ring 51, thereby driving the cleaning drum 5 to slowly rotate clockwise inside the outer machine compartment 1, and the large pulley 61 drives the drive cleaning structure 7 to rotate counterclockwise quickly through the transmission belt 63.

[0033] In this embodiment, the drive cleaning structure 7 includes a transmission shaft 71 whose bearing penetrates the outer machine compartment 1 and the cleaning drum 5. Both ends of the transmission shaft 71 are respectively rotatably connected to the connecting secondary compartment 2 and the connecting frame 8 by bearings. Outside the transmission shaft 71 and inside the cleaning drum 5, a spiral shunt pipe 73 is fixed, and a drive cleaning structure 74 is fixed in the middle of the transmission shaft 71. Outside the transmission shaft 71 near the connecting frame 8, a lower pulley 72 is fixed and is in transmission connection with the transmission belt 63.

[0034] Specifically, the large pulley 61 drives the small pulley through the transmission belt 63, so that the transmission shaft 71 rotates quickly, driving the spiral shunt pipe 73 and the drive cleaning structure 74 to rotate to perform frictional flushing on the medicinal materials.

[0035] In this embodiment, the inside of the transmission shaft 71 is hollow, and at one end of the transmission shaft 71 located at the connecting frame 8, a rotary joint is movably connected to the external high-pressure water pipeline, and at the same time, the external high-pressure water pipeline is controlled electrically to input high-pressure water liquid into the drive cleaning structure 7 for combined flushing.

[0036] In this embodiment, the spiral shunt pipe 73 is evenly provided with a plurality of water spray holes 731 on the end face facing the cleaning drum 5, and the middle of the spiral shunt pipe 73 is connected to the drive cleaning structure 74. The water liquid enters the spiral shunt pipe 73 and is spirally sprayed from the plurality of water spray holes 731 into the rolling cleaning drum 5.

[0037] Embodiment 2, on the basis of Embodiment 1, the drive cleaning structure 74 includes a connecting plate 741 fixed on the transmission shaft 71. The outer end of the connecting plate 741 is fixed with a power structure 742. Both side ends of the power structure 742 are rotatably connected to a connecting shaft 743 by bearings, and cleaning soft brushes 744 are evenly fixed on the outer surface of the connecting shaft 743. The power structure 742 includes a power box 7421 fixedly connected to the connecting plate 741. The inside of the connecting plate 741 is hollow, and a partition plate 7425 is fixedly connected in the middle of the connecting plate 741. The partition plate 7425 divides the inside of the connecting plate 741 into a water inlet channel and a water outlet channel. Among them, the water inlet channel is communicated with the transmission shaft 71, and the water outlet channel is communicated with the spiral shunt pipe 73. Inside the power box 7421, a cleaning spray head 7423 is obliquely fixed on one side, and the cleaning spray head 7423 is communicated with the water inlet channel. An inlet 7424 is opened at a position near the cleaning spray head 7423 in the power box 7421 and is communicated with the water outlet channel. On the inner surface of the power box 7421 where the connecting shaft 743 is located, a rotary blade 7422 is fixed.

[0038] Specifically, the high-pressure water liquid enters the hollow transmission shaft 71 through the rotatably connected joint, and enters the water inlet channel of the connecting plate 741 along the channel, and then enters the greenhouse power structure 742 to provide rotational power for the connecting shaft 743, driving the cleaning soft brush 744 evenly installed on the surface to rotate and clean. That is, the high-pressure water liquid sprays out from the inclined cleaning nozzle 7423 and enters the power box 7421. The inclined high-pressure water liquid impacts on the rotating blades 7422, driving the rotating blades 7422 to rotate, thereby driving the connecting shaft 743 and the installed cleaning soft brush 744 to rotate. After the power box 7421 is filled with water liquid, it enters the water outlet channel of the connecting plate 741 from the water inlet hole, and finally enters the spiral shunt pipe 73, and is spirally sprayed from multiple spray holes 731 into the rolling cleaning drum 5. The medicinal material conveying and scattering material is inside the cleaning drum 5. The transmission shaft 71 drives the spiral shunt pipe 73 to make the water liquid be spirally sprayed inside the cleaning drum 5 to clean the medicinal materials. The sewage generated by the cleaning is filtered through multiple filter holes 52 and enters the bottom of the outer machine compartment 1, and is discharged through the discharge pipe 12. During the cleaning process, the transmission shaft 71 drives the driving and cleaning structure 74 to rotate, which can stir the medicinal materials to make them more evenly dispersed for cleaning. During the stirring process, the rotating cleaning soft brush 744 can dynamically contact and rub with the stirred medicinal materials, which can effectively clean the dust and stains on the surface of the medicinal materials, thereby accelerating the cleaning efficiency and cleanliness of the medicinal materials.

[0039] Among them, the cleaning nozzle 7423 is inclined and cooperates with the rotating blades 7422 to drive rotation. The high-pressure water liquid sprays out from the inclined cleaning nozzle 7423 and enters the power box 7421. The inclined high-pressure water liquid impacts on the rotating blades 7422, driving the rotating blades 7422 to rotate.

[0040] Embodiment 3, on the basis of Embodiment 1, the scattering structure 9 includes a large gear 94 fixed on the transmission shaft 71 and a connecting seat 91 fixed at the bottom of the outlet of the conveying pipeline. The connecting seat 91 is rotatably connected with a rotating shaft 92. Multiple groups of material distributing blades 93 are fixed outside the rotating shaft 92. A small gear 921 is also fixed outside the rotating shaft 92 and meshes with the large gear 94. The medicinal materials are poured into the feeding bin 3, and the medicinal materials slide into the rolling cleaning drum 5 through the inclined conveying pipeline. At this time, the rotating transmission shaft 71 drives the large gear 94 to rotate, and the large gear 94 drives the small gear 921 to make its rotating shaft 92 rotate accordingly. The rotating shaft 92 drives the rotating blades 7422 to rotate, and scatters the extension sliding out of the conveying channel to the periphery of the cleaning drum 5, so as to facilitate the medicinal materials to be quickly spread out for cleaning work.

[0041] Among them, each group of material distributing blades 93 is in a parabolic curved shape, and the edges of the material distributing blades 93 are upturned. The medicinal materials can be slapped to a farther place in the cleaning drum 5 through the parabolic curved material distributing blades 93, accelerating the spreading of the medicinal materials.

[0042] Working principle:

[0043] This device is controlled by an external control electric box. When working, the reduction motor 6 is started. The reduction motor 6 drives the large pulley 61 and the driving gear 62 through the output shaft. Among them, the driving gear 62 meshes with the gear ring 51, thereby driving the cleaning drum 5 to slowly rotate clockwise inside the outer machine compartment 1. The large pulley 61 drives the driving cleaning structure 7 to rotate counterclockwise quickly through the transmission belt 63, and drives the material scattering structure 9 to drive and scatter the materials. At the same time, the external high-pressure water pipeline is controlled electrically to input high-pressure water liquid into the driving cleaning structure 7 for flushing in cooperation;

[0044] The large pulley 61 drives the small pulley through the transmission belt 63, thereby driving the transmission shaft 71 to rotate quickly, driving the spiral shunt pipe 73 and the driving cleaning structure 74 to rotate for friction washing of the medicinal materials. The high-pressure water liquid enters the hollow transmission shaft 71 through the rotationally connected joint, and enters the water inlet channel of the connecting plate 741 along the channel, and then enters the greenhouse power structure 742 to provide rotational power for the connecting shaft 743, driving the cleaning soft brush 744 evenly installed on the surface to rotate and clean. That is, the high-pressure water liquid sprays out from the inclined cleaning nozzle 7423 and enters the power box 7421. The inclined high-pressure water liquid impacts on the rotating blade 7422, driving the rotating blade 7422 to rotate, thereby driving the connecting shaft 743 and the installed cleaning soft brush 744 to rotate. After the power box 7421 is filled with water liquid, it enters the water outlet channel of the connecting plate 741 from the water inlet hole, and finally enters the spiral shunt pipe 73, and is spirally sprayed from multiple spray holes 731 into the rolling cleaning drum 5;

[0045] The experimenter pours the medicinal materials into the feeding bin 3, and the medicinal materials slide into the rolling cleaning drum 5 through the inclined conveying pipeline. At this time, the rotating transmission shaft 71 drives the large gear 94 to rotate. The large gear 94 drives the small gear 921 to make its rotating shaft 92 rotate accordingly. The rotating shaft 92 drives the rotating blade 7422 to rotate, and scatters the extension sliding out from the conveying channel to the periphery of the cleaning drum 5, so as to facilitate the medicinal materials to be quickly spread out for cleaning work. The medicinal materials are conveyed and scattered inside the cleaning drum 5 by multiple inclined baffles 53 arranged spirally in the cleaning drum 5. The transmission shaft 71 drives the spiral shunt pipe 73 to make the water liquid be spirally sprayed inside the cleaning drum 5 to clean the medicinal materials. The sewage generated by the cleaning is filtered through multiple filter holes 52 and enters the bottom of the outer machine compartment 1, and the sewage is discharged through the discharge pipe 12. During the cleaning process, the transmission shaft 71 drives the driving cleaning structure 74 to rotate, which can stir the medicinal materials to make them more evenly dispersed for cleaning. During the stirring process, the rotating cleaning soft brush 744 can dynamically contact and rub with the stirred medicinal materials, which can effectively clean the dust and stains on the surface of the medicinal materials, thereby accelerating the cleaning efficiency and cleanliness of the medicinal materials;

[0046] After the cleaning is completed, open the sealing cover of the discharge port 21, and then control the reduction motor 6 to turn over, driving the cleaning drum 5 to rotate counterclockwise. The rolling cleaning drum 5 is assisted by a plurality of inclined material plates 53 arranged in a spiral to drive the cleaned medicinal materials to be displaced to the discharge port 21 for discharge.
