Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb cleaning technology, and in particular to an integrated equipment for cleaning and drying Chinese medicinal herbs. Background Technology

[0002] After harvesting, Chinese medicinal herbs often have impurities such as mud, sand, insect eggs, and pesticide residues attached to their surface. They must undergo thorough cleaning before proceeding with subsequent processing steps such as preparation, slicing, or drying. As the first step in processing Chinese medicinal herbs, the effectiveness of cleaning directly affects the quality and safety of the final product.

[0003] The cleaning process of Chinese medicinal herbs requires a large amount of clean water, but the cleaning water used by existing cleaning equipment is mostly for single use and is discharged directly. Although some equipment is equipped with a circulating filtration system, when multiple cleaning methods are used, the water with different levels of pollution generated at different cleaning stages is filtered and treated uniformly without distinction, resulting in poor cleaning effects in subsequent stages. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an integrated cleaning and drying equipment for Chinese medicinal materials, which can filter water with different levels of pollution generated in different cleaning stages, thereby improving the effect of subsequent cleaning.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A comprehensive equipment for cleaning and drying Chinese medicinal herbs, comprising:

[0007] Base

[0008] A cleaning chamber is connected to and supported by a base; the cleaning chamber has a accommodating space, a first drain outlet, and a second drain outlet, the accommodating space being used for placing Chinese medicinal herbs;

[0009] The transmission mechanism is used to move the Chinese medicinal materials along the length of the cleaning tank.

[0010] A circulating water tank has a first receiving cavity and a second receiving cavity. The first receiving cavity is connected to a first drain outlet, and the second receiving cavity is connected to a second drain outlet. The circulating water tank is provided with a first filter element, a second filter element, and a partition. The first filter element is located in the first receiving cavity, and the second filter element is located in the second receiving cavity. The first filter element and the second filter element have different filtration accuracies. The partition is located between the first receiving cavity and the second receiving cavity to separate the first receiving cavity and the second receiving cavity.

[0011] A first cleaning component is disposed in the cleaning chamber and is connected to the first accommodating cavity; the first cleaning component is used to perform preliminary cleaning of Chinese medicinal materials.

[0012] The second cleaning component is disposed in the cleaning chamber and is connected to the second accommodating cavity; the second cleaning component is used to perform deep cleaning of Chinese medicinal materials.

[0013] A drying mechanism is used to dry the cleaned Chinese medicinal materials.

[0014] Furthermore, the average size of the filter pores in the first filter element is greater than the average size of the filter pores in the second filter element.

[0015] Furthermore, the first cleaning component includes a bubbling tube section and a first water pump. The bubbling tube section is located at the bottom of the cleaning chamber and within the accommodating space. The inlet of the first water pump is connected to the first accommodating cavity, and the outlet of the first water pump is connected to the bubbling tube section.

[0016] Furthermore, the second cleaning component includes a spray pipe section and a second water pump. The spray pipe section is located at the top of the cleaning tank and is supported by the cleaning tank. The spray nozzle of the spray pipe section faces the accommodating space. The inlet of the second water pump is connected to the second accommodating cavity, and the outlet of the second water pump is connected to the spray pipe section.

[0017] Furthermore, the spray pipe section is provided with multiple spray heads, which are distributed at intervals along the length and width directions of the cleaning tank.

[0018] Furthermore, the cleaning chamber includes a feeding section, a cleaning section, and a draining section arranged sequentially along its length. The feeding section is arranged inclined downwards along the length of the cleaning chamber; the cleaning section is arranged horizontally along the length of the cleaning chamber; and the draining section is arranged inclined upwards along the length of the cleaning chamber.

[0019] Furthermore, the transmission mechanism is a mesh conveyor belt.

[0020] Furthermore, the transmission mechanism is provided with multiple baffles, which are distributed at intervals along the movement direction of the transmission mechanism; the baffles are used to prevent the Chinese medicinal materials from sliding down from the draining section.

[0021] Furthermore, the drying mechanism is located at the discharge end of the draining section; the drying mechanism includes a drying chamber, a blower, and a drying conveyor belt; the blower is located inside the drying chamber, the blower is used to blow hot air toward the Chinese medicinal materials, and the drying conveyor belt is used to allow the Chinese medicinal materials to pass through the air outlet of the blower in sequence.

[0022] Furthermore, the drying conveyor belt includes an inclined section and a horizontal section connected in sequence. The inclined section is arranged inclined downward along the length direction of the washing box, and the horizontal section is arranged along the length direction of the washing box. There are two blowers, which are distributed above the inclined section and above the horizontal section.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The circulating water tank has a first receiving cavity and a second receiving cavity. The first receiving cavity is connected to the first drain outlet, and the second receiving cavity is connected to the second drain outlet. The circulating water tank has a first receiving cavity and a second receiving cavity, which are separated by a partition and are physically independent of each other. The first receiving cavity is connected to the first drain outlet through a pipe, and the second receiving cavity is connected to the second drain outlet through a pipe. The two receiving cavities receive water from different drain outlets and serve different cleaning stages. The water in the two circulation loops operates independently and does not interfere with each other.

[0025] 2. The circulating water tank is equipped with a first filter element, a second filter element, and a partition. The first filter element is located in a first receiving cavity; the second filter element is located in a second receiving cavity; the first filter element and the second filter element have different filtration accuracies; the partition is located between the first receiving cavity and the second receiving cavity to separate them. The first receiving cavity contains the first filter element. Water flowing into the first receiving cavity passes through the first filter element during storage, and impurities in the water are trapped and retained in the first receiving cavity, resulting in the filtered water accumulating in the first receiving cavity. The second receiving cavity contains the second filter element. Water flowing into the second receiving cavity passes through the second filter element during storage, and impurities in the water are trapped and retained in the second receiving cavity, resulting in the filtered water accumulating in the second receiving cavity. The first chamber receives water from the preliminary cleaning stage. In this stage, the suspended impurities in the water are relatively large, so a lower filtration precision is sufficient to meet the treatment requirements. Simultaneously, the lower filtration precision maintains a high filtration flux, allowing a large volume of water to pass through per unit time with low filtration resistance, thus meeting the large water volume requirements of the preliminary cleaning stage. The second chamber receives water from the deep cleaning stage. In this stage, the suspended impurities in the water are relatively small, and a higher filtration precision effectively traps these fine particles. The filtered water in the second chamber has a lower impurity content and higher cleanliness, meeting the water cleanliness requirements of the deep cleaning stage. This ensures the effective recycling of water from different cleaning stages, improving the cleaning effect in subsequent cleaning processes. Attached Figure Description

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] See Figures 1-4The present invention illustrates a preferred embodiment of an integrated cleaning and drying device for Chinese medicinal materials, comprising a base 1, a cleaning chamber 2, a transmission mechanism 3, a circulating water tank 4, a first cleaning component 5, a second cleaning component 6, and a drying mechanism 7.

[0035] The cleaning box 2 is connected to and supported by the base 1; the cleaning box 2 has a accommodating space 21, a first drain outlet 22 and a second drain outlet 23, and the accommodating space 21 is used for placing Chinese medicinal materials.

[0036] The base 1 serves as the supporting foundation for the equipment. Placed on the mounting surface, the base 1 provides stable support for the entire equipment, ensuring its fixed position during operation. The cleaning chamber 2 is a long, rectangular box structure with an internal storage space 21 for holding the medicinal herbs. The cleaning chamber 2 is equipped with a first drain outlet 22 and a second drain outlet 23. The storage space 21 extends along the length of the cleaning chamber 2, within which the medicinal herbs undergo cleaning. The first drain outlet 22 and the second drain outlet 23 are located at different positions within the cleaning chamber 2, respectively, to drain water with varying degrees of contamination generated during the cleaning process. The cleaning chamber 2 can be made of stainless steel to withstand the humid environment during the medicinal herb cleaning process and meet hygiene requirements.

[0037] The transmission mechanism 3 is used to move the Chinese medicinal materials along the length of the cleaning box 2.

[0038] The conveying mechanism 3 is installed inside the cleaning chamber 2, and its running direction is consistent with the length direction of the cleaning chamber 2. The medicinal herbs are placed on the conveying mechanism 3 and move from one end of the cleaning chamber 2 to the other as the conveying mechanism 3 operates. The running speed of the conveying mechanism 3 can be adjusted according to the type of medicinal herbs and the cleaning requirements.

[0039] The circulating water tank 4 has a first receiving cavity 41 and a second receiving cavity 42. The first receiving cavity 41 is connected to the first drain outlet 22, and the second receiving cavity 42 is connected to the second drain outlet 23. The circulating water tank 4 is provided with a first filter element 43, a second filter element 44, and a partition 45. The first filter element 43 is located in the first receiving cavity 41, and the second filter element 44 is located in the second receiving cavity 42. The first filter element 43 and the second filter element 44 have different filtration accuracies. The partition 45 is located between the first receiving cavity 41 and the second receiving cavity 42 to separate the first receiving cavity 41 and the second receiving cavity 42.

[0040] Water in the internal storage space 21 of the cleaning tank 2 can flow out of the cleaning tank 2 through the first drain outlet 22 and then into the first receiving cavity 41; water in the internal storage space 21 of the cleaning tank 2 can also flow out of the cleaning tank 2 through the second drain outlet 23 and then into the second receiving cavity 42 along the second drain pipe. The first receiving cavity 41 and the second receiving cavity 42 are used to hold water from the cleaning tank 2 during different cleaning processes, respectively. A partition 45 divides the internal space of the circulating water tank 4 into two independent cavities: the first receiving cavity 41 and the second receiving cavity 42. The first receiving cavity 41 and the second receiving cavity 42 are physically isolated by the partition 45; water in the first receiving cavity 41 cannot pass through the partition 45 to enter the second receiving cavity 42, and water in the second receiving cavity 42 cannot pass through the partition 45 to enter the first receiving cavity 41. The connection between the partition 45 and the circulating water tank 4 is a sealed connection structure to prevent water leakage between the two receiving cavities. When water flowing into the first receiving cavity 41 passes through the first filter element 43, impurities in the water are trapped by the first filter element 43. The filtered water passes through the first filter element 43 and is stored in the first receiving cavity 41, awaiting delivery to the first cleaning element 5. A second filter element 44 is disposed in the second receiving cavity 42, located on the water flow path between the inlet and outlet of the second receiving cavity 42. When water flowing into the second receiving cavity 42 passes through the second filter element 44, impurities in the water are trapped by the second filter element 44. The filtered water passes through the second filter element 44 and is stored in the second receiving cavity 42, awaiting delivery to the second cleaning element 6. Since the water received by the first receiving cavity 41 comes from the preliminary cleaning stage, the suspended impurity particles in this water are relatively large. The first filter element 43 uses a lower filtration precision, with relatively large filter holes or gaps, allowing smaller particles in the water to pass through, while mainly trapping larger particles whose diameter exceeds its filtration precision. When the first filter element 43 operates at a lower filtration precision, it allows a larger volume of water to pass through per unit time with lower filtration resistance, meeting the large water volume requirements of the initial cleaning stage. The water received by the second receiving chamber 42 comes from the deep cleaning stage. In this water, the suspended impurities are smaller. The second filter element 44 employs a higher filtration precision, with relatively smaller pore or gap sizes, effectively trapping smaller particles in the water. When the second filter element 44 operates at a higher filtration precision, the output water has a lower impurity content and higher cleanliness, meeting the water cleanliness requirements of the deep cleaning stage. The first filter element 43 and the second filter element 44 can take the form of a filter screen, filter cotton, or a filter. For example, the first filter element 43 can be a filter screen with a larger pore size (such as a 20-mesh sieve), and the second filter element 44 can be a filter screen with a smaller pore size (such as a 100-mesh sieve). Alternatively, the first filter element 43 can be a combination of a filter screen and a sedimentation tank, and the second filter element 44 can be a combination of multiple layers of filter screen and filter cotton.

[0041] The first cleaning component 5 is located in the cleaning chamber 2 and is connected to the first accommodating cavity 41; the first cleaning component 5 is used to perform preliminary cleaning of Chinese medicinal materials.

[0042] The preliminary cleaning is mainly used to remove larger particulate impurities, such as mud and sand, attached to the surface of Chinese medicinal materials. After the preliminary cleaning, the water carrying the larger particulate impurities flows back to the first receiving cavity 41 through the first drain outlet 22, is filtered by the first filter element 43, and is then transported back to the cleaning tank 2 by the first cleaning element 5, forming the first circulating water path.

[0043] The second cleaning component 6 is located in the cleaning chamber 2 and is connected to the second accommodating cavity 42; the second cleaning component 6 is used to perform deep cleaning of Chinese medicinal materials.

[0044] Deep cleaning is mainly used to remove fine particulate impurities, insect eggs, and some pesticide residues from the surface of Chinese medicinal materials. After deep cleaning, the water carrying fine particulate impurities flows back to the second containment chamber 42 through the second drain outlet 23, is filtered by the second filter element 44, and is then transported back to the cleaning tank 2 by the second cleaning element 6, forming the second circulating water path.

[0045] The drying unit 7 is used to dry the cleaned Chinese medicinal materials.

[0046] The drying mechanism 7 can be set at the discharge end of the cleaning chamber 2 to receive the cleaned Chinese medicinal materials output from the cleaning chamber 2, and to dry the Chinese medicinal materials to reduce their moisture content so that they reach the required dryness for subsequent processing or storage.

[0047] The working principle of the integrated cleaning and drying equipment for Chinese medicinal materials of this invention is as follows: Before starting the equipment, the operator injects clean water into the first receiving chamber 41 and the second receiving chamber 42. The operator puts the Chinese medicinal materials to be cleaned into the cleaning tank 2, and the materials fall onto the conveying mechanism 3. The first cleaning component 5 transports the clean water in the first receiving chamber 41 into the receiving space 21 of the cleaning tank 2, and performs preliminary cleaning on the Chinese medicinal materials. During the preliminary cleaning process, larger particles such as mud and sand adhering to the surface of the Chinese medicinal materials are removed from the surface and enter the water. The water carrying the larger particles flows out of the cleaning tank 2 through the first drain outlet 22 and enters the first receiving chamber 41 of the circulating water tank 4 along the first drain pipe. The water entering the first receiving chamber 41 flows through the first filter element 43, which traps the larger particles in the water. The filtered water is stored in the first receiving chamber 41 and is then transported back to the receiving space 21 of the cleaning tank 2 by the first cleaning component 5, realizing the recycling of the water used for preliminary cleaning. Next, after all the water used for preliminary cleaning in the cleaning tank 2 has flowed back to the first receiving chamber 41, the second cleaning unit 6 is activated to perform a deep cleaning of the Chinese medicinal materials. During the deep cleaning process, fine particulate impurities and insect egg residues remaining on the surface of the Chinese medicinal materials detach from the surface and enter the water. The water carrying the fine particulate impurities flows out of the cleaning tank 2 through the second drain outlet 23 and enters the second receiving chamber 42 of the circulating water tank 4 along the second drain pipe. The water entering the second receiving chamber 42 flows through the second filter element 44, which traps the fine particulate impurities in the water. The filtered water is stored in the second receiving chamber 42 and then transported back to the receiving space 21 of the cleaning tank 2 by the second cleaning unit 6, realizing the recycling of water for deep cleaning. After cleaning, the conveying mechanism 3 moves the Chinese medicinal materials to the drying mechanism 7, which dries the Chinese medicinal materials to reduce their moisture content.

[0048] The cleaning tank 2 is connected to and supported by the base 1. The cleaning tank 2 has a accommodating space 21, a first drain outlet 22, and a second drain outlet 23. The accommodating space 21 is used to place Chinese medicinal materials. The base 1 serves as the supporting foundation of the equipment, placed on the mounting plane, providing stable support for the entire equipment. When the equipment is in operation, the vibrations and loads generated by the cleaning tank 2, the circulating water tank 4, and various moving parts are transmitted to the base 1, which receives and distributes them to the mounting plane. The relative positions between the various components of the equipment are thus maintained, and the fitting accuracy between the mechanisms will not be lost due to the vibrations generated during operation. The cleaning tank 2 is provided with a first drain outlet 22 and a second drain outlet 23, which are respectively located at different positions in the cleaning tank 2. The water generated in the preliminary cleaning stage is discharged from the first drain outlet 22, and the water generated in the deep cleaning stage is discharged from the second drain outlet 23. Due to the different drainage paths, the two waters are separated when discharged from the cleaning tank 2, and the waters with different levels of pollution generated in different cleaning stages will not mix during the drainage process.

[0049] The conveyor mechanism 3 is used to move the Chinese medicinal herbs along the length of the cleaning tank 2. When the conveyor mechanism 3 is running, the Chinese medicinal herbs are placed on it and move from the inlet to the outlet of the cleaning tank 2 with the conveyor mechanism 3. There is no need for manual transfer between each cleaning process, and the cleaning operation can be carried out continuously.

[0050] The circulating water tank 4 has a first receiving cavity 41 and a second receiving cavity 42. The first receiving cavity 41 is connected to a first drain outlet 22, and the second receiving cavity 42 is connected to a second drain outlet 23. The circulating water tank 4 is equipped with a first filter element 43, a second filter element 44, and a partition 45. The first filter element 43 is located in the first receiving cavity 41, and the second filter element 44 is located in the second receiving cavity 42. The first filter element 43 and the second filter element 44 have different filtration accuracies. The partition 45 is located between the first receiving cavity 41 and the second receiving cavity 42 to separate them. The circulating water tank 4 has a first receiving cavity 41 and a second receiving cavity 42, which are separated by a partition 45 and are physically independent of each other. The first receiving chamber 41 is connected to the first drain outlet 22 via a pipe, and the second receiving chamber 42 is connected to the second drain outlet 23 via a pipe. The two receiving chambers receive water from different drain outlets and serve different cleaning stages. The water in the two circulation loops operates independently without interference. The first receiving chamber 41 is equipped with a first filter element 43. Water flowing into the first receiving chamber 41 passes through the first filter element 43 during storage, and impurities in the water are trapped and retained within the first receiving chamber 41. The filtered water accumulates within the first receiving chamber 41. The second receiving chamber 42 is equipped with a second filter element 44. Water flowing into the second receiving chamber 42 passes through the second filter element 44 during storage, and impurities in the water are trapped and retained within the second receiving chamber 42. The filtered water accumulates within the second receiving chamber 42. The water received in the first receiving chamber 41 comes from the preliminary cleaning stage. In this stage, the suspended impurities in the water are relatively large, so a lower filtration precision is sufficient to meet the treatment requirements. Simultaneously, the lower filtration precision maintains a high filtration flux, allowing a large volume of water to pass through per unit time with low filtration resistance, thus meeting the large water volume requirements of the preliminary cleaning stage. The water received in the second receiving chamber 42 comes from the deep cleaning stage. In this stage, the suspended impurities in the water are relatively small, and a higher filtration precision can effectively trap these fine particles. The filtered water in the second receiving chamber 42 has a lower impurity content and higher cleanliness, meeting the water cleanliness requirements of the deep cleaning stage. This ensures the effective recycling of water from different cleaning stages, improving the cleaning effect in subsequent cleaning processes.

[0051] The first cleaning component 5 is installed in the cleaning chamber 2 and connected to the first receiving cavity 41; the first cleaning component 5 is used for preliminary cleaning of the Chinese medicinal materials; the second cleaning component 6 is installed in the cleaning chamber 2 and connected to the second receiving cavity 42; the second cleaning component 6 is used for deep cleaning of the Chinese medicinal materials; the drying mechanism 7 is used for drying the cleaned Chinese medicinal materials. The first cleaning component 5 washes away larger particles such as mud and sand adhering to the surface of the Chinese medicinal materials. These impurities enter the water body and flow with the water towards the first drain outlet 22, and then flow back to the first receiving cavity 41 through the first drain outlet 22, completing the preliminary cleaning cycle. The second cleaning component 6 washes away fine particles, insect eggs, and other residues remaining on the surface of the Chinese medicinal materials. These impurities enter the water body and flow with the water towards the second drain outlet 23, and then flow back to the second receiving cavity 42 through the second drain outlet 23, completing the deep cleaning cycle. After initial and deep cleaning, the surface of the Chinese medicinal herbs still retains a significant amount of moisture. If this moisture is not removed promptly, the herbs are prone to mold or spoilage during subsequent storage or processing. Once the herbs enter the drying unit 7, the moisture adhering to their surface is removed, reducing the moisture content to a level that is unlikely to support microbial growth. Therefore, the cleaned herbs remain dry and meet the requirements for subsequent processing or storage.

[0052] Preferably, the average pore size of the first filter element 43 is larger than the average pore size of the second filter element 44. The water received by the first receiving chamber 41 comes from the preliminary cleaning stage. In this stage, the suspended impurity particles in the water are relatively large, and a lower filtration precision is sufficient to meet the treatment requirements. At the same time, the lower filtration precision results in a larger pore size, allowing a larger volume of water to pass through per unit time, and lower filtration resistance, which can meet the large water volume requirements of the preliminary cleaning stage. The water received by the second receiving chamber 42 comes from the deep cleaning stage. In this stage, the suspended impurity particles in the water are relatively small, and a higher filtration precision can effectively trap the fine particles, resulting in a lower impurity content and higher cleanliness in the water output from the second receiving chamber 42, which can meet the water cleanliness requirements of the deep cleaning stage.

[0053] Preferably, the first cleaning component 5 includes a bubble tube section 51 and a first water pump 52. The bubble tube section 51 is located at the bottom of the cleaning tank 2 and within the accommodating space 21. The inlet of the first water pump 52 is connected to the first accommodating cavity 41, and the outlet of the first water pump 52 is connected to the bubble tube section 51. The bubble tube section 51 is located at the bottom and has air or water outlets distributed on its surface. The first water pump 52 pumps water from the first accommodating cavity 41 into the bubble tube section 51. When gas is introduced into the bubble tube section 51, the gas enters the accommodating space 21 through the air outlet and mixes with the water to form bubbles. As the bubbles rise, they disturb the water, causing the medicinal herbs in the water to tumble within the accommodating space 21. During the tumbling process, the surfaces of the medicinal herbs come into full contact with the water, and the soil and sand adhering to them are detached under the scouring of the water and the impact of the bubbles. When water is introduced into the bubbling tube section 51, the water flows out of the tube section and forms a flowing water stream at the bottom of the cleaning tank 2, which has a rinsing effect on the Chinese medicinal materials. The two working modes can be selected or used in combination depending on the type of Chinese medicinal materials and the characteristics of the impurities adhering to their surface. It can be understood that the bubbling tube section 51 has both air and water circulation functions; different cleaning methods can be achieved by switching the supply medium without replacing the cleaning components.

[0054] Preferably, the second cleaning component 6 includes a spray pipe section 61 and a second water pump 62. The spray pipe section 61 is located at the top of the cleaning chamber 2 and is supported by the cleaning chamber 2. The spray nozzle of the spray pipe section 61 faces the accommodating space 21. The inlet of the second water pump 62 is connected to the second accommodating cavity 42, and the outlet of the second water pump 62 is connected to the spray pipe section 61. The second water pump 62 pumps the filtered water in the second accommodating cavity 42 into the spray pipe section 61. The water is sprayed into the Chinese medicinal materials in the accommodating space 21 in the form of a jet stream through the spray nozzle of the spray pipe section 61. The spray pipe section 61 is located at the top of the cleaning chamber 2, and the spray nozzle faces the Chinese medicinal materials from top to bottom. The jet stream accelerates downward under the action of gravity and has a certain impact force when it reaches the surface of the Chinese medicinal materials. This impact force acts on the surface of the Chinese medicinal materials and washes away the small impurities that are still remaining on the surface of the Chinese medicinal materials after the initial cleaning. Under the influence of gravity, the jet stream passes through the layer of Chinese medicinal herbs and falls to the bottom of the cleaning tank 2, carrying away the impurities and flowing towards the second drain outlet 23.

[0055] Preferably, the spray pipe section 61 is equipped with multiple spray heads, which are distributed at intervals along the length and width directions of the cleaning chamber 2. The spray heads form an array in the length and width directions of the cleaning chamber 2, with the spray ranges of adjacent spray heads connecting in the width direction and arranged sequentially in the length direction, thus forming a continuous spray coverage area above the accommodating space 21 of the cleaning chamber 2. When the medicinal materials pass through this area with the conveyor mechanism 3, they are covered by the spray flow throughout the entire width direction, with no unsprayed dead corners, and all parts of the surface of the medicinal materials are impacted and cleaned by the spray flow. In the length direction, the medicinal materials are sprayed sequentially by multiple spray heads, with each spray carrying away a portion of residual impurities. After multiple consecutive sprays, the total amount of residual impurities on the surface of the medicinal materials gradually decreases.

[0056] Preferably, the cleaning tank 2 includes a feeding section 24, a cleaning section 25, and a draining section 26 arranged sequentially along its length. The feeding section 24 is inclined downwards along the length of the cleaning tank 2; the cleaning section 25 is horizontally arranged along the length of the cleaning tank 2; and the draining section 26 is inclined upwards along the length of the cleaning tank 2. With the feeding section 24 inclined downwards, after the operator puts the medicinal herbs into the feeding section 24, the herbs slide down the inclined surface of the feeding section 24 to the cleaning section 25 under gravity, eliminating the need for an additional pushing device and making the feeding process smoother. With the cleaning section 25 horizontally arranged, the medicinal herbs are in a horizontal state while running within the cleaning section 25, allowing for uniform water distribution and consistent water depth throughout the entire cleaning section 25. This ensures that the water force acting on the medicinal herbs during the cleaning process remains balanced throughout, preventing inconsistent cleaning results due to changes in water depth. The draining section 26 is inclined upward. The Chinese medicinal materials move upward along the inclined surface under the drive of the conveying mechanism 3. The water adhering to the surface of the Chinese medicinal materials flows downward along the surface of the Chinese medicinal materials under the action of gravity and flows back to the washing section 25. When the Chinese medicinal materials reach the discharge end of the draining section 26, a large amount of water adhering to the surface has been removed. The initial moisture content when entering the drying mechanism 7 is low, and the total amount of water that the drying mechanism 7 needs to remove is reduced.

[0057] Preferably, the conveying mechanism 3 is a mesh conveyor belt. The surface of the mesh conveyor belt has mesh openings, allowing water and detached impurities to pass through the mesh and fall to the bottom of the cleaning chamber 2 during the washing process, preventing them from remaining on the conveyor belt surface. When the medicinal herbs are placed on the mesh conveyor belt, their bottoms contact the water below the conveyor belt through the mesh openings. Impurities at the bottom of the herbs can also be carried away by the water through the mesh openings, avoiding the situation where the bottom of the herbs cannot be cleaned due to the conveyor belt isolating the water. In the draining section 26, water passes through the mesh openings and the layer of medicinal herbs under gravity, ensuring smooth drainage and high drainage efficiency.

[0058] Preferably, the conveying mechanism 3 is provided with multiple baffles 8, which are distributed at intervals along the movement direction of the conveying mechanism 3. The baffles 8 are used to prevent the Chinese medicinal materials from sliding down the draining section 26. The baffles 8 are fixedly installed on the surface of the conveying mechanism 3 and move synchronously with the conveying mechanism 3, with a certain interval between each baffle 8 along the movement direction of the conveying mechanism 3. The draining section 26 of the washing box 2 is inclined upward along the length direction of the washing box 2, and the conveying mechanism 3 also moves inclined upward within the draining section 26. The Chinese medicinal materials are placed on the conveying mechanism 3 and move upward with it, tending to slide downward along the surface of the conveying mechanism 3 under the action of gravity. The baffles 8 move with the conveying mechanism 3 during its operation, located behind the Chinese medicinal materials they support, and provide an upward blocking force on the Chinese medicinal materials along the movement direction of the conveying mechanism 3, so that the Chinese medicinal materials do not slide down the slope due to gravity. The spacing between adjacent baffles 8 limits the accumulation range of each group of Chinese medicinal herbs on the conveying mechanism 3. If the spacing is too large, the herbs will accumulate too thickly on the inclined surface of the draining section 26, and the friction between the upper layer of herbs and the conveying mechanism 3 will be insufficient to overcome the component force on the inclined surface, making them prone to rolling off. If the spacing is too small, the amount of herbs that can be accommodated per unit length of the conveying mechanism 3 will decrease, reducing the conveying efficiency. By setting an appropriate spacing, the herbs can maintain a stable accumulation state during the inclined conveying process and smoothly ascend with the conveying mechanism 3 to the discharge end of the draining section 26.

[0059] Preferably, the drying mechanism 7 is located at the discharge end of the draining section 26; the drying mechanism 7 includes a drying chamber 71, a blower 72, and a drying conveyor belt 73; the blower 72 is located inside the drying chamber 71 and is used to blow hot air onto the Chinese medicinal materials, while the drying conveyor belt 73 allows the Chinese medicinal materials to pass sequentially through the air outlet of the blower 72. The drying chamber 71 supports the blower 72, which blows hot air onto the Chinese medicinal materials, transferring heat to them. This causes the moisture adhering to the surface of the Chinese medicinal materials to evaporate into water vapor, which then flows with the hot air or is discharged from the chamber. The hot air blown by the blower 72 directly acts on the surface of the Chinese medicinal materials passing through the drying conveyor belt 73. The flow rate and temperature of the hot air allow the moisture on the surface of the Chinese medicinal materials to gain sufficient heat and evaporate in a short time, rapidly reducing the moisture content of the Chinese medicinal materials. The drying conveyor belt 73 operates continuously. After being discharged from the drain section 26, the medicinal herbs are directly transferred to the drying conveyor belt 73. During transport, they pass sequentially through the air outlet area of ​​the blower 72, continuously receiving hot air throughout the process. It can be understood that the blower 72 can be equipped with multiple air outlets distributed along the conveying direction of the drying conveyor belt 73, ensuring that the medicinal herbs are continuously dried with hot air throughout the transport process, resulting in a more uniform drying effect.

[0060] Preferably, the drying conveyor belt 73 includes an inclined section 731 and a horizontal section 732 connected in sequence. The inclined section 731 is arranged inclined downwards along the length of the washing chamber 2, and the horizontal section 732 is arranged along the length of the washing chamber 2. Two blowers 72 are provided, distributed above the inclined section 731 and above the horizontal section 732. The two blowers 72 are respectively arranged above the inclined section 731 and above the horizontal section 732. The blower 72 above the inclined section 731 performs preliminary drying on the Chinese medicinal materials that have just entered the drying chamber 71, removing free moisture from the surface of the Chinese medicinal materials. The blower 72 above the horizontal section 732 further dries the Chinese medicinal materials after the free moisture on the surface of the Chinese medicinal materials has been removed, removing bound moisture inside the tissue and attached to the surface of the Chinese medicinal materials. After the Chinese medicinal materials are subjected to the hot air action of the two blowers 72, the moisture content is reduced twice, resulting in more thorough drying.
