Description

Technical Field

[0001] The present invention relates to the field of traditional Chinese medicine cleaning, and more particularly to a batch cleaning line and cleaning method for traditional Chinese medicine. Background Art

[0002] In the traditional Chinese medicine processing industry, efficient and high-quality cleaning and sorting of traditional Chinese medicinal materials are key links to ensure the quality of traditional Chinese medicine. The Chinese patent with the application number CN202023128550.1 provides a stainless steel traditional Chinese medicine sorting table solution to improve the efficiency and quality of traditional Chinese medicine cleaning and sorting. When in use, the traditional Chinese medicinal materials are placed in a pipeline, and the brushes arranged inside the pipeline become the first line of defense for cleaning. As the medicinal materials move inside the pipeline, the brushes come into full contact with the surface of the medicinal materials, and part of the dust is effectively removed through friction. When the medicinal materials move to a specific position, the material pushing rod starts to play a role. It disperses the gathered medicinal materials to avoid accumulation, facilitating subsequent sorting. At the same time, a collection pipe located on one side of the material pushing rod uses the suction generated by the top to suck the dust on the surface of the medicinal materials into the pipe through a filter plate, and then through the connection with the conveying pipe, the preliminarily cleaned medicinal materials enter the conveying link; this technical solution successfully replaces part of the manual cleaning work, significantly improves the cleaning efficiency, and reduces the labor cost; moreover, by reducing the dust on the surface of the medicinal materials, it enables the operator to more clearly observe the surface condition of the medicinal materials, facilitating sorting and improving the accuracy of sorting to a certain extent. However, on the one hand, its cleaning function is mainly concentrated on the surface of the medicinal materials, and the cleaning depth and effect are limited. In actual situations, there are various types of impurities on the surface of traditional Chinese medicinal materials. In addition to dust, there are also soil, residual pesticides, microorganisms, etc. These impurities may adhere to the gaps and folds of the medicinal materials, and it is difficult to completely remove them only by brushes and suction. For example, for medicinal materials such as honeysuckle with a delicate stamen structure, it is easy to hide dirt inside, and it is difficult for this sorting table to deeply clean the stamens; for medicinal materials such as ginseng with textured epidermis, the impurities in the texture cannot be effectively removed either. These residual impurities will seriously affect the quality of traditional Chinese medicine, reduce its medicinal value, and may even cause problems in subsequent processing and use. On the other hand, this solution does not consider the characteristic differences of different types of medicinal materials. Different medicinal materials have different requirements for cleaning methods, intensities, and times, and this sorting table adopts a unified cleaning mode, which cannot meet the diverse needs. For some fragile medicinal materials, the friction of the brushes may cause damage; for medicinal materials rich in oil or viscous substances, the existing cleaning methods are difficult to completely wash them clean. In the current pursuit of high-quality traditional Chinese medicine, this surface-only cleaning solution is difficult to meet the strict requirements of the modern traditional Chinese medicine industry for cleaning quality.

[0024] Cleaning method for a traditional Chinese medicine batch cleaning line. On the support frame of the transmission unit, the first motor drives the first transmission roller to rotate, causing the first conveyor belt to operate. The baffles distributed on the outer surface of the first conveyor belt push the traditional Chinese medicine to be transported obliquely upward and convey the traditional Chinese medicine to the vibration unit;

[0025] The vibration motor of the drive unit drives the driving wheel to rotate. The driving wheel drives the driven wheel through the connecting belt, causing the rotating disk to rotate. The rotating rod eccentrically connected to the rotating disk drives the connecting rod to move, thereby driving the vibration frame to reciprocate along the length direction of the machine frame. The traditional Chinese medicine vibrates on the vibration frame, and the impurities fall through the leakage holes, enter the dust collection box through the dust collection cover and the flexible tube. Under the vibration action, the traditional Chinese medicine in the upper half of the vibration frame enters the hopper through the discharge channel between the guiding members;

[0026] The traditional Chinese medicine in the hopper falls into the cleaning cylinder. The water pipe is connected to an external water source, and water is sprayed onto the traditional Chinese medicine in the cleaning cylinder through the nozzle. The power motor of the power unit drives the driving sprocket, and the driving sprocket drives the driven sprocket through the chain, causing the cleaning cylinder to rotate. The spiral guiding strips on the inner wall of the cleaning cylinder push the traditional Chinese medicine to tumble and move in the cleaning cylinder, and the sewage flows into the water collection tank through the through holes on the cleaning cylinder and the drain port at the lower end of the positioning cylinder; The guiding plate in the water collection tank guides the flow of sewage, and the solid impurities remain in the solid collection frame. The sewage flows into the bottom of the water collection tank through the first drain hole and the second drain hole;

[0027] The cleaned traditional Chinese medicine is discharged from the discharge port of the cleaning cylinder and falls on the second conveyor belt of the conveying assembly. The conveying motor drives the second conveying roller, causing the second conveyor belt to move. The traditional Chinese medicine moves along with the second conveyor belt. The wind blown by the fan on the fan frame dries the traditional Chinese medicine. The moisture generated during the drying process falls into the water storage cavity through the water drainage holes on the second conveyor belt and then flows into the water storage tank through the pipeline;

[0028] The dried traditional Chinese medicine passes through the guiding plate below the output end of the second conveyor belt and falls into the aggregate frame on the conveyor belt. The conveying motor drives the third conveying roller, causing the conveyor belt to operate. Then the operator collects the aggregate frame containing the traditional Chinese medicine.

[0029] The present invention has the following beneficial effects:

[0030] 1. The vibration frame of the vibration unit is inclined and has leakage holes in the upper half. Under the action of the drive unit, it reciprocates, enabling the impurities to fall through the leakage holes during the vibration of the traditional Chinese medicine, enter the dust collection box through the dust collection cover and the flexible tube, effectively removing most of the soil attached to the surface of the traditional Chinese medicine, reducing the difficulty of subsequent cleaning with clear water, and improving the cleaning effect;

[0031] 2. The cleaning cylinder of the cleaning unit rotates under the drive of the power unit, and the spiral guiding strips on the inner wall push the traditional Chinese medicine to tumble and move. Combined with the spraying of water by the nozzle, it can penetrate into the gaps, folds and other parts of the medicinal materials, thoroughly removing impurities such as soil, residual pesticides, and microorganisms. The cleaning depth and effect are superior to the prior art;

[0032] 3. A guide plate and a solid collection frame are arranged in the water collection tank. The guide plate guides the flow of sewage, causing solid impurities to remain in the solid collection frame. The sewage flows into the bottom of the water collection tank through the drainage holes, facilitating the centralized collection and treatment of solid impurities.

[0033] 4. The blower of the air-drying unit dries the Chinese medicine after cleaning. The generated moisture falls into the water storage cavity through the water drainage holes of the second conveyor belt and then flows into the water storage tank through the pipeline, realizing the recycling of water resources. It not only achieves the purpose of drying the Chinese medicine but also saves water resources.

[0034] 5. A feeding frame mechanism is arranged on the transmission rack. Operators can stack multiple aggregate frames between the L-shaped limit pieces, and control the movement of the limit table through the cylinder to achieve the one-by-one placement of the aggregate frames, eliminating the need for operators to continuously place them manually and reducing labor intensity.

[0077] Cleaning method of traditional Chinese medicine batch cleaning line

[0078] The traditional Chinese medicine is conveyed to the vibration unit 2 through the conveying unit 1 to remove impurities, then enters the cleaning unit 12 for cleaning, is dried by the drying unit 22 afterwards, and finally is collected by the conveyor belt 27 and the aggregate frame 28, realizing the batch cleaning and collection of the traditional Chinese medicine.

[0079] The operator places the traditional Chinese medicine on the conveying unit 1, on the support frame 29 of the conveying unit 1. The first motor 32 drives the first conveying roller to rotate, so that the first conveyor belt 30 operates. The baffles 31 distributed on the outer surface of the first conveyor belt 30 push the traditional Chinese medicine to be conveyed obliquely upwards and convey the traditional Chinese medicine to the vibration unit 2;

[0080] The vibration motor of the driving unit 11 drives the driving wheel 51 to rotate. The driving wheel 51 drives the driven wheel 50 through the connecting belt 52, so that the rotating disc 38 rotates. The rotating rod 37 eccentrically connected to the rotating disc 38 drives the connecting rod 36 to move, and then drives the vibration frame 3 to make a reciprocating motion along the length direction of the machine frame 9. The arranged driving wheel 51 makes its swing smoother; the traditional Chinese medicine vibrates on the vibration frame 3, and the impurities fall from the leakage holes 5, pass through the dust collection hood 70 and the flexible tube and enter the dust collection box 71. Through the above method, the soil attached to the surface of the Chinese medicinal materials is cleaned, so that most of the attached soil falls off after the first cleaning, reducing the difficulty of subsequent cleaning with clear water and achieving a better cleaning effect. Since the vibration frame 3 needs to swing while the dust collection box 71 is fixed, the present invention connects the dust collection hood 70 and the dust collection box 71 through a flexible connection. Under the vibration action, the traditional Chinese medicine in the upper half of the vibration frame 3 enters the hopper 10 through the discharge channel 7 between the guiding members 6;

[0081] The traditional Chinese medicine in the hopper 10 falls into the cleaning cylinder 17. The water pipe 63 is externally connected to a water source, and water is sprayed onto the traditional Chinese medicine in the cleaning cylinder 17 through the nozzle 65. The power motor of the power unit 21 drives the driving chain wheel, and the driving chain wheel drives the driven chain wheel 68 through the chain 69, causing the cleaning cylinder 17 to rotate. The spiral guide strips 66 on the inner wall of the cleaning cylinder 17 push the traditional Chinese medicine to roll and move in the cleaning cylinder 17, and the sewage flows into the water collection tank 13 through the through holes 18 on the cleaning cylinder 17 and the drain port 16 at the lower end of the positioning cylinder 15; the guide plate 56 in the water collection tank 13 guides the flow of the sewage, and the solid impurities remain in the solid collection frame 61, and the sewage flows into the bottom of the water collection tank 13 through the first drain hole 60 and the second drain hole 62;

[0082] The cleaned traditional Chinese medicine is discharged from the discharge port 20 of the cleaning cylinder 17 and falls on the second conveyor belt 73 of the conveying assembly 23. The conveying motor 76 drives the second conveying roller, causing the second conveyor belt 73 to move, and the traditional Chinese medicine moves along with the second conveyor belt 73. The air blown by the blower 26 on the blower frame 82 dries the traditional Chinese medicine, and the moisture generated during the drying process falls into the water storage cavity 77 through the water drainage holes 75 on the second conveyor belt 73 and then flows into the water storage tank 79 through the pipeline 78;

[0083] The dried traditional Chinese medicine passes through the guide plate 80 under the output end of the second conveyor belt 73 and falls into the aggregate frame 28 on the conveyor belt 27. The conveyor motor drives the third conveyor roller, causing the conveyor belt 27 to operate, and then the operator collects the aggregate frame 28 containing the traditional Chinese medicine.

[0084] The aggregate frames 28 are placed on the conveyor belt 27 one by one through the blanking frame mechanism 85. The specific steps are as follows:

[0085] The operator stacks several aggregate bins 28 between the L-shaped limiters 97. When it is necessary to place the lowermost aggregate bin 28 on the conveyor belt 27, two second cylinders 93 drive two symmetrically arranged second limit platforms 88 to move in opposite directions. (Since there are multiple overlapping aggregate bins 28, for the convenience of description and understanding, the aggregate bin 28 is divided into aggregate bin A1 and aggregate bin B1). Since the two second limit platforms 88 no longer support the aggregate bin A1, the aggregate bin A1 drops onto the conveyor belt 27. At this time, the aggregate bin B1 is at the lowermost position. Subsequently, the two second cylinders 93 push the two second limit platforms 88 in the relative direction to prepare for supporting the aggregate bin B1. The first cylinder 92 retracts the two first limit platforms 87, so that the aggregate bin B1 falls onto the two second limit platforms 88. The aggregate bins are lowered in accordance with the above steps. With the above settings, the operator can place multiple aggregate bins on the discharge bin mechanism 85, and the discharge bin mechanism 85 sequentially lowers the aggregate bins, eliminating the need for the operator to continuously place aggregate bins on the conveyor belt 27, reducing the labor intensity of the operator. The aggregate bins are made of plastic material and are relatively light in weight. However, it should be noted that avoid placing too many or too high aggregate bins on the discharge bin mechanism 85 at one time, which may reduce the service life of the discharge bin mechanism 85.

[0086] During cleaning, to further improve the cleaning effect, the present invention provides the parameters for cleaning some medicinal materials:

[0087] For rhizome medicinal materials: When ginseng is cleaned, it is necessary to remove surface impurities while avoiding damage. The rotation speed of the cleaning cylinder is controlled at 20 - 30 revolutions per minute, which can not only make the medicinal materials fully tumble in the cleaning cylinder but also prevent collision damage caused by too high a rotation speed. The water spray volume of the nozzle is 8 - 10 liters per minute, ensuring that the water flow can fully cover the surface of the medicinal materials and effectively wash away impurities. The air speed of the fan is set at 4 - 5 meters per second, and the drying time is 15 - 20 minutes, which can quickly dry the cleaned medicinal materials without damaging the surface of the medicinal materials due to too high an air speed. When astragalus is cleaned, the rotation speed of the cleaning cylinder can be controlled at 30 - 40 revolutions per minute, the water spray volume is 6 - 8 liters per minute, the air speed of the fan is 5 - 6 meters per second, and the drying time is 12 - 18 minutes. Astragalus is slightly softer in texture but has more fibers than ginseng. Appropriately increasing the rotation speed and air speed helps for better cleaning and drying.

[0088] Leaf category: Mulberry leaves are large and thin. The rotation speed of the cleaning cylinder is 15 - 25 revolutions per minute, the water volume is 5 - 8 liters per minute, the air speed of the fan is 4 - 6 meters per second, and the drying time is 10 - 15 minutes. When cleaning, attention should be paid to avoiding leaf breakage. Appropriate rotation speed and water spraying volume can effectively remove surface impurities, and the air speed of the fan can be adjusted according to the dryness of the leaves. Mint leaves have volatile components. The rotation speed of the cleaning cylinder is 10 - 20 revolutions per minute, the water spraying volume is 4 - 6 liters per minute, and the air speed of the fan is 3 - 5 meters per second. A lower air speed can reduce the loss of volatile components and maintain the aroma and medicinal effect of mint leaves.

[0089] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
