Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb extraction technology, specifically to a Chinese medicinal herb concentration and extraction device and extraction method that integrates waste residue anti-clogging. Background Technology

[0002] In the process of concentrating and extracting Chinese medicinal materials, in order to fully extract the components, the medicinal materials need to be fully immersed in water. However, the medicinal materials are not fully squeezed, resulting in the inability to fully extract the components.

[0003] Chinese Patent Publication No. CN116061485B discloses a traditional Chinese medicine extraction device, including an extraction cylinder, a stirring device, and an end cap detachably installed at the top of the extraction cylinder. The extraction cylinder is equipped with an annular filter plate, which divides the extraction cylinder into a central cavity and an annular cavity. The stirring device includes a drive mechanism mounted on the end cap and a stirring section inserted into the central cavity, the stirring section being connected to the drive mechanism. A vertically movable pressure plate is inserted into the annular cavity, and the pressure plate is connected to the drive mechanism via a transmission device. The stirring section includes a part whose top end is rotatably mounted through the end cap. The extraction cylinder has a drive shaft and a sleeve that slides up and down on the drive shaft. Multiple stirring rods are fixedly installed on the outer surface of the sleeve. The bottom wall of the extraction cylinder is provided with a limiting groove. The bottom end of the drive shaft is inserted into the limiting groove. A vibrating sleeve is fixedly installed on the bottom end of the sleeve and is fitted onto the drive shaft. The bottom surface of the vibrating sleeve is inclined. A top rod is fixedly installed on the bottom wall of the extraction cylinder. The top end of the top rod abuts against the bottom surface of the vibrating sleeve. A limiting structure is provided between the drive shaft and the sleeve to restrict their relative rotation. The upper end of the drive shaft is connected to the drive mechanism.

[0004] The above-mentioned method processes Chinese medicinal herbs through extrusion extraction. However, under extrusion, the herbs gradually turn into a slag-like structure, which clogs the annular filter plate. Specifically, under pressure, the waste herbs in the annular cavity are squeezed into the filter holes of the annular filter plate, causing blockage. Water flow alone cannot remove this clogged waste. The annular filter plate needs cleaning after a period of use. Furthermore, the extrusion of the herbal residue is achieved using a conveyor belt, which has limited pressure and is prone to breakage, increasing operating costs and hindering the extraction of sufficient herbal components. Additionally, the extruded waste herbs cannot be discharged automatically, requiring manual cleaning. The inability of the device to automatically rotate further complicates the cleaning process, limiting the concentration and extraction efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a traditional Chinese medicine (TCM) concentration and extraction device and method that integrates waste residue anti-clogging technology. After extraction, the receiving plate is driven to descend to the discharge position and rotates at high speed. Simultaneously, the pressing action of the pressing plate and the tearing action of the protrusions on the receiving plate efficiently separate the compressed TCM residue and use centrifugal force to quickly eject it from the extraction area. This mechanism completely changes the situation where traditional equipment struggles to automatically discharge TCM residue, achieving automated and clean discharge of the residue.

[0006] To address the problems of existing technologies, this invention provides a traditional Chinese medicine concentration and extraction device with integrated waste residue anti-clogging mechanism. This extraction device is connected to a concentration and distillation device and includes an extraction tank and an annular filter plate. It also includes a pressing plate, a receiving plate, a first linear actuator, and a rotating unit. The pressing plate is vertically movable within the annular filter plate and has a circular structure with a diameter equal to the inner diameter of the annular filter plate. The receiving plate is positioned below the pressing plate and moves vertically. When the receiving plate is stationary within the annular filter plate, it is in the receiving position; when it is below the annular filter plate, it is in the discharge position. The first linear actuator is vertically positioned below the receiving plate and drives the receiving plate to move up and down. The rotating unit is located on one side of the receiving plate and drives the receiving plate at the discharge position to rotate.

[0007] Preferably, multiple protrusions are fixedly provided on the upper end surface of the receiving plate.

[0008] Preferably, a discharge slope is provided below the extraction barrel. The discharge slope has a ring structure, with the inner ring height being higher than the outer ring height. When the receiving plate is in the discharge position, the upper end face of the receiving plate is at the same height as the inner ring of the discharge slope.

[0009] Preferably, the receiving plate has an upper half and a lower half along its axis, the diameter of the upper half being the same as the inner ring diameter of the discharge slope, and the lower half contracting from top to bottom towards the center along its axis.

[0010] Preferably, a collection shell is provided at the lower part of the discharge slope, and the collection shell is used to collect the liquid medicine.

[0011] Preferably, a rotating shaft is vertically installed through the bottom of the collecting shell. The upper end of the rotating shaft is fixedly connected to the receiving plate, and the lower end of the rotating shaft is rotatably engaged with the output end of the first linear actuator. The rotating unit is used to drive the rotating shaft to rotate, and the diameter of the rotating shaft is smaller than the diameter of the lower half of the receiving plate.

[0012] Preferably, an extension ring is fixedly provided at the bottom of the collecting shell, the rotating shaft passes through the inner ring of the extension ring, the outer ring diameter of the extension ring is smaller than the lower end diameter of the lower half of the receiving plate, and the periphery of the extension ring and the collecting shell form a water storage area.

[0013] Preferably, a raised flange is vertically fixed at the lower end of the lower half. The raised flange has a ring structure, and the inner diameter of the raised flange is larger than the outer diameter of the extension ring.

[0014] Preferably, a guide hopper is fixedly provided on the upper part of the annular filter plate, and the guide hopper has a funnel-shaped structure.

[0015] This invention also relates to a method for concentrating and extracting traditional Chinese medicine with integrated waste residue anti-clogging technology, employing a device for concentrating and extracting traditional Chinese medicine with integrated waste residue anti-clogging technology. The specific steps are as follows:

[0016] S1. Extract the medicinal liquid. The receiving plate is in the receiving position. The receiving plate receives the put-in medicinal materials. The pressing plate descends into the annular filter plate to squeeze the medicinal materials.

[0017] S2. Discharge the liquid medicine from the extraction tank;

[0018] S3. Discharge waste residue. The receiving plate and the pressing plate descend synchronously. When the receiving plate descends to the discharge position, it stops descending and rotates under the drive of the rotating unit. The pressing plate continues to descend while the receiving plate is rotating, so that the blocky waste residue is decomposed and discharged under the action of centrifugal force. After the waste residue is discharged, the receiving plate returns to the receiving position, and the pressing plate rises above the annular filter plate, and the cycle repeats.

[0019] The advantages of this invention compared to the prior art are:

[0020] 1. This invention, after extraction, drives the receiving plate to descend to the discharge position and rotates at high speed. Simultaneously, the pressing action of the pressing plate and the tearing action of the protrusions on the receiving plate efficiently separate the compressed medicinal residue, and uses centrifugal force to quickly eject it from the extraction area. This mechanism completely changes the situation where traditional equipment struggles to automatically discharge medicinal residue, achieving automated and clean discharge without manual intervention, thereby improving production efficiency and fundamentally avoiding mechanical damage to the annular filter plate that may be caused by manual cleaning.

[0021] 2. By setting an annular discharge slope and interception bin around the annular filter plate, this invention ensures that the waste residue thrown from the receiving plate can be accurately guided and collected. The discharge slope not only serves as a guide, but its slightly higher inner ring design also helps prevent premature loss of the extractant or mixing with the waste residue during extraction. The interception bin effectively captures all the waste residue thrown out by centrifugal force, preventing it from splashing onto other parts of the equipment or the surrounding environment, greatly simplifying subsequent waste residue collection and cleaning work, and maintaining the cleanliness of the surrounding environment.

[0022] 3. By adding an automatic cleaning unit consisting of a perforator, a push pin, and a drive unit to the annular gaps of the annular filter plate, this invention achieves online self-cleaning of the filter pores of the annular filter plate. After each slag discharge process, the cleaning unit can drive the push pin to accurately align and penetrate the filter pores, effectively removing fine waste particles that may have become embedded during the extraction process. This key design successfully solves the long-standing problem of filter plate clogging in the industry, ensuring unobstructed filter pores. This not only ensures the filtration efficiency and chemical quality of subsequent batches of extraction but also further extends the service life of the annular filter plate and reduces production interruptions caused by frequent shutdowns for cleaning.

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-5 and Figure 7 A traditional Chinese medicine concentration and extraction device integrating waste residue anti-clogging, the extraction device is connected to a concentration and distillation device, the extraction device includes an extraction tank 1 and an annular filter plate 11; the extraction device also includes a pressing plate 12, a receiving plate 13, a first linear actuator 14 and a rotating unit 15; the pressing plate 12 is vertically movable in the annular filter plate 11, the pressing plate 12 has a circular structure, and the diameter of the pressing plate 12 is the same as the inner ring diameter of the annular filter plate 11; the receiving plate 13 is located below the pressing plate 12 and moves vertically, when the receiving plate 13 is in the annular filter plate 11 and is in a stationary state, the receiving plate 13 is in the receiving position, and when the receiving plate 13 is below the annular filter plate 11, the receiving plate 13 is in the discharge position; the first linear actuator 14 is vertically arranged below the receiving plate 13 and is used to drive the receiving plate 13 to rise and fall; the rotating unit 15 is arranged on one side of the receiving plate 13 and is used to drive the receiving plate 13 located at the discharge position to rotate.

[0037] In the actual production scenario of extracting medicinal materials from Chinese herbal medicines, in order to fully utilize the medicinal properties of the herbs, existing technologies generally rely on extrusion precipitation to separate the effective components. However, this process has significant technical bottlenecks, the most prominent being the clogging problem of the annular filter plate 11. Under continuous extrusion, the Chinese herbal medicines gradually break down into fine slag-like structures. These waste particles, driven by pressure, continuously accumulate towards the annular filter plate 11. Because the filter plate's pores need to balance filtration accuracy and water flow efficiency, their pore size is within a specific range. The slag-like waste particles from the Chinese herbal medicines easily embed themselves inside these pores, forming stubborn blockages. Unlike the surface adhesion of ordinary impurities, this type of blockage is caused by the deep embedding of waste particles under pressure. Relying solely on the water flow during the extraction process is insufficient to generate enough impact force to completely flush away the blockages, causing the filtration channel to gradually narrow, thereby affecting the flow efficiency of the medicinal liquid.

[0038] Furthermore, the waste residue treatment and equipment cleaning processes are inconvenient, especially the residual medicinal residue in the annular filter plate 11, which is difficult to remove and has become one of the key factors restricting the concentration and extraction efficiency. The compressed medicinal waste residue is in block form and has formed a tight bond with the filter holes and plate surface of the annular filter plate 11 under pressure, rather than being a simple loose accumulation. During the compression process, this waste residue seeps into the gaps and deep holes of the filter plate, and some fibrous waste residue will also become entangled with each other, forming a firm bond with the filter plate. It cannot be naturally removed by its own gravity or the flow of medicinal liquid, so the waste residue cannot be automatically discharged by the equipment itself and must be cleaned manually.

[0039] Meanwhile, the difficulty of manual cleaning further exacerbates this problem. Existing extraction devices, limited by their structural design, lack a self-rotating function. The installation position of the annular filter plate 11 is relatively fixed, and the internal space of the equipment is narrow, making it difficult for operators to directly access critical areas such as the inner side of the filter plate and the corners of the annular cavity. During cleaning, because the medicinal residue is compressed into chunks, a certain decomposition force is required to break it down. However, due to the limited operating space and the need for significant decomposition force, the annular filter plate 11 is easily damaged during decomposition.

[0040] More importantly, the accumulation of residual residue can create a vicious cycle. If not thoroughly cleaned after each extraction, the remaining waste becomes the "impurity base" for the next batch. Newly generated residue will adhere to the old residue, further exacerbating filter pore blockage and plate adhesion problems. This not only leads to a geometric increase in the difficulty of subsequent cleaning but also affects the filtration accuracy and extraction purity of the solution. Some residual waste may even deteriorate, potentially impacting the quality of the solution. Furthermore, frequent and complex manual cleaning consumes a significant amount of production time, shortening the effective operating time of the equipment and extending the batch extraction interval. Ultimately, this keeps the efficiency of the entire concentration and extraction process consistently low, making it difficult to meet the demands of large-scale, continuous production.

[0041] To avoid the aforementioned situation, the existing concentration and extraction device was optimized so that the extraction device of this invention can automatically discharge the residue after squeezing the Chinese medicinal materials, eliminating the need for manual cleaning, thus improving production efficiency and avoiding damage to the annular filter plate 11 during cleaning. The specific structure and working process of this invention are as follows: An opening 16 is provided on the side wall of the extraction tank 1. During daily extraction, the medicinal materials are added through the opening 16 of the extraction tank 1, falling into the annular filter plate 11. At this time, the receiving plate 13 is located inside the annular filter plate 11, in the receiving position. A sealing ring is provided on the outer periphery of the receiving plate 13 to reduce the leakage rate of the medicinal liquid between the receiving plate 13 and the annular filter plate 11. A rated amount of water is injected into the extraction tank 1. An annular gap exists between the extraction tank 1 and the annular filter plate 11. The water injected into the extraction tank 1 is distributed in the annular gap and at the inner ring of the annular filter plate 11, and the liquid level is the same. A second linear actuator 121 is provided on the upper part of the pressing plate 12. The second linear actuator 121 drives the pressing plate 12 to descend and squeeze the Chinese medicinal materials inside the annular filter plate 11. At this time, the receiving plate 13 is in a stationary state. As the pressing plate 12 continues to descend, the receiving plate 13 and the pressing plate 12 exert a squeezing effect on the Chinese medicinal materials in the annular filter plate 11, causing the juice in the Chinese medicinal materials to be squeezed out. The waste residue of the Chinese medicinal materials after squeezing is left in the annular filter plate 11. A drain port 17 is provided at the lower part of the extraction tank 1, through which the medicinal liquid is first discharged.

[0042] After the liquid medicine is drained, the receiving plate 13 and the pressing plate 12 descend synchronously. The receiving plate 13 descends from the receiving position to the discharge position, at which point the receiving plate 13 is below the annular filter plate 11, and the compressed medicine residue is located between the receiving plate 13 and the pressing plate 12. At this time, the medicine residue cannot be discharged because when the receiving plate 13 just descends to the discharge position, the rotating unit 15 has not yet been started, and the medicine residue between the receiving plate 13 and the pressing plate 12 is not subjected to external force, so it will not disintegrate and be discharged. When the rotating unit 15 is started, the receiving plate 13 rotates, and the pressing plate 12, under the action of the second linear actuator 121, presses the medicine residue, causing the compressed medicine residue to disintegrate and be thrown out under the centrifugal force generated by the receiving plate 13. Subsequently, both the receiving plate 13 and the pressing plate 12 rise. The receiving plate 13 stops after rising to the receiving position, while the pressing plate 12 continues to rise. When the height of the pressing plate 12 is higher than the upper height of the annular filter plate 11, the pressing plate 12 stops to ensure that when Chinese medicinal materials are added later, they can smoothly enter the annular filter plate 11 without being blocked by the pressing plate 12, and the cycle repeats.

[0043] Reference Figure 11 Multiple protrusions 131 are fixedly provided on the upper end surface of the receiving plate 13.

[0044] By setting multiple protrusions 131 on the upper surface of the receiving plate 13, the protrusions 131 can be used to pull the compressed drug residue when the receiving plate 13 rotates, thereby enabling the drug residue to disintegrate quickly and improving the discharge efficiency of the drug residue.

[0045] Reference Figure 7 A discharge slope 2 is provided below the extraction barrel 1. The discharge slope 2 is a ring structure. The height of the inner ring of the discharge slope 2 is higher than the height of the outer ring. When the receiving plate 13 is in the discharge position, the upper end face of the receiving plate 13 is at the same height as the inner ring of the discharge slope 2.

[0046] By setting a discharge slope 2 below the extraction tank 1, the waste residue can be smoothly discharged under the guidance of the receiving plate 13. An interception chamber 21 is set around the discharge slope 2. The interception chamber 21 has a ring structure and surrounds the discharge slope 2. Since the receiving plate 13 uses centrifugal force to complete the feeding, some of the residue will be thrown out under the action of centrifugal force. The interception chamber 21 intercepts the thrown residue, preventing it from flying around the extraction device and being difficult to collect and clean. A discharge port 22 is opened through the bottom of the interception chamber 21. A scraper 23 is rotatably arranged around the axis of the interception chamber 21. When the scraper 23 rotates in the interception chamber 21, it can push the waste residue accumulated in the interception chamber 21 to the discharge port 22 for discharge. A first drive unit 24 is set on the interception chamber 21 to drive the scraper 23 to rotate. The first drive unit 24 is preferably a gear transmission, which can be referred to... Figure 5The first drive unit 24 includes a first motor, a first transmission gear, and a first transmission gear ring. The first motor is vertically mounted on one side of the extraction barrel 1. The first transmission gear is fixedly mounted at the end of the first motor. The first transmission gear ring is rotatably fitted around the extraction barrel 1 along its axis. The first transmission gear meshes with the first transmission gear ring. The scraper 23 is connected to the first transmission gear ring and can rotate synchronously with it. Since the first drive unit 24, which has the function of driving the scraper 23 to rotate around its axis, is prior art, it will not be described in detail here.

[0047] Reference Figure 6 The receiving plate 13 has an upper half 132 and a lower half 133 along its axis. The diameter of the upper half 132 is the same as the inner ring diameter of the discharge slope 2. The lower half 133 shrinks from top to bottom towards the center along its axis.

[0048] Because a discharge slope 2 is provided below the annular filter plate 11, if the upper and lower diameters of the receiving plate 13 are the same, when the extraction tank 1 extracts the Chinese medicinal materials, a small amount of medicinal liquid will seep out through the gap between the receiving plate 13 and the annular filter plate 11. At this time, some of the seeped medicinal liquid will fall onto the discharge slope 2 and be discharged from the discharge slope 2. To avoid the above problem, the receiving plate 13 is divided into an upper half 132 and a lower half 133, so that the lower half 133 contracts from top to bottom towards the center along its axis. When medicinal liquid seeps out, under the guidance of the lower half 133, the medicinal liquid will drip from the inner ring of the discharge slope 2 instead of falling onto the upper part of the discharge slope 2, thus avoiding the loss of medicinal liquid.

[0049] Reference Figure 3 , Figure 6 and Figure 7 A collection shell 3 is provided at the lower part of the discharge slope 2. The collection shell 3 is used to collect the liquid medicine.

[0050] The seeping liquid is guided by the lower half 133 of the receiving plate 13, passes through the inner ring of the discharge slope 2 and falls into the collection shell 3. A circulation pipe is installed on the collection shell 3, and a water pump is installed on the circulation pipe. The water pump draws the liquid in the collection shell 3 back to the extraction tank 1 through the circulation pipe.

[0051] Reference Figure 9 and Figure 10 A rotating shaft 31 is vertically installed through the bottom of the collecting shell 3. The upper end of the rotating shaft 31 is fixedly connected to the receiving plate 13, and the lower end of the rotating shaft 31 is rotatably engaged with the output end of the first linear driver 14. The rotating unit 15 is used to drive the rotating shaft 31 to rotate. The diameter of the rotating shaft 31 is smaller than the diameter of the lower half 133 of the receiving plate 13.

[0052] A limiting groove 311 is formed on the side wall of the rotating shaft 31. The rotating unit 15 includes a gear ring 151, a gear 152, and a rotary driver 153. The gear ring 151 is sleeved on the rotating shaft 31 and is rotatably disposed at the bottom of the collecting shell 3. The inner ring of the gear ring 151 extends into the limiting groove 311 of the rotating shaft 31. The gear ring 151 and the limiting groove 311 slide in the vertical direction. When the gear ring 151 rotates, the rotating shaft 31 rotates synchronously with the gear ring 151. The gear 152 is rotatably disposed on one side of the gear ring 151 and meshes with the gear ring 151. The rotary driver 153 is disposed at the end of the gear 152 and is used to drive the gear 152 to rotate. This enables the rotating shaft 31 to both move up and down in the vertical direction and rotate on its own axis.

[0053] Reference Figure 6 and Figure 7 An extension ring 32 is fixedly installed at the bottom of the collection shell 3. The rotating shaft 31 passes through the inner ring of the extension ring 32. The outer ring diameter of the extension ring 32 is smaller than the lower end diameter of the lower half 133 of the receiving plate 13. The outer periphery of the extension ring 32 and the collection shell 3 form a water storage area.

[0054] The water storage area is used to store the medicine liquid. By setting the extension ring 32, the medicine liquid is prevented from seeping out from the gap between the rotating shaft 31 and the collection shell 3.

[0055] Reference Figure 4 and Figure 6 A raised flange 134 is vertically fixed at the lower end of the lower half 133. The raised flange 134 is a ring structure, and the inner diameter of the raised flange 134 is larger than the outer diameter of the extension ring 32.

[0056] By setting the raised flange 134, the liquid medicine is prevented from forming droplets on the lower end face of the receiving plate 13 and flowing freely. Guided by the lower half 133 of the receiving plate 13, the liquid medicine eventually gathers at the lower end of the raised flange 134. Since the inner diameter of the raised flange 134 is larger than the outer diameter of the extension ring 32, when the droplets gather to a certain extent, they will drip into the water storage area.

[0057] Reference Figure 5 , Figure 7 and Figure 8 A guide bucket 111 is fixedly installed on the upper part of the annular filter plate 11. The guide bucket 111 has a funnel-shaped structure.

[0058] By setting the guide hopper 111, when the medicinal materials are put into the extraction tank 1 from the opening 16, they first fall onto the guide hopper 111 and then into the annular filter plate 11. A cleaning unit 4 is also provided in the annular gap. The cleaning unit 4 includes a through-hole device 41 and a second drive unit 42, as shown in the reference... Figure 11The second drive unit 42 includes a second motor, a second transmission gear, and a second transmission gear ring. The second motor is vertically mounted on the outside of the extraction barrel 1. The second transmission gear is fixedly mounted on the end of the second motor. The second transmission gear ring is rotatably mounted inside the extraction barrel 1 along its axis. The second transmission gear passes through the side wall of the extraction barrel 1 and meshes with the second transmission gear ring. The through-hole device 41 is connected to the second transmission gear ring. When the second transmission gear ring rotates, the through-hole device 41 rotates synchronously with it. The through-hole device 41 is rotatably mounted in the annular gap around the axis of the annular filter plate 11. A pin 411 is horizontally mounted in the through-hole device 41. The pin 411 is electromagnetically driven to extend and retract. The second drive unit 42 is mounted on the upper part of the through-hole device 41 and is used to drive the through-hole device 41 to move. After the liquid is discharged, the receiving plate 13 and the pressing plate 12 descend synchronously. The receiving plate 13 stops and rotates after descending to the discharge position. When the pressing plate 12 descends to the designated height, it begins to rise, while the receiving plate 13 remains rotating. When the pressing plate 12 rises above the annular filter plate 11, the second drive unit 42 drives the through-hole device 41 to rotate, aligning the ejector pin 411 on the through-hole device 41 with the filter holes on the annular filter plate 11. Since the included angle between adjacent filter holes distributed in a ring is fixed and known in advance, the second drive unit 42 can drive the through-hole device 41 to rotate at a predetermined angle, ensuring that the ejector pin 411 is aligned with the filter hole. The ejector pin 411 extends under electromagnetic action and cleans the waste residue clogging the filter hole. After cleaning, the ejector pin 411 retracts under electromagnetic drive, and the receiving plate 13 stops rotating and rises back to the receiving position.

[0059] Reference Figures 1-11 This invention also relates to a method for concentrating and extracting traditional Chinese medicine with integrated waste residue anti-clogging technology, employing a device for concentrating and extracting traditional Chinese medicine with integrated waste residue anti-clogging technology. The specific steps are as follows:

[0060] S1. Extract the medicinal liquid. The receiving plate 13 is in the receiving position. The receiving plate 13 receives the put-in medicinal materials. The pressing plate 12 descends into the annular filter plate 11 to squeeze the medicinal materials.

[0061] S2. Discharge the liquid medicine, drain the liquid medicine from extraction tank 1;

[0062] S3. Discharge waste residue. The receiving plate 13 and the pressing plate 12 descend synchronously. When the receiving plate 13 descends to the discharge position, it stops descending and rotates under the drive of the rotating unit 15. The pressing plate 12 continues to descend while the receiving plate 13 is rotating, so that the blocky waste residue is decomposed and discharged under the action of centrifugal force. After the waste residue is discharged, the receiving plate 13 returns to the receiving position, and the pressing plate 12 rises above the annular filter plate 11, and the cycle repeats.

[0063] Working principle: Before extraction, the receiving plate 13 is positioned within the annular filter plate 11, with its outer sealing ring tightly fitting the inner wall of the annular filter plate 11, effectively reducing the risk of liquid leakage. The guide bucket 111 guides the medicinal materials from the extraction bucket 1 opening 16 into the inner ring of the annular filter plate 11 through a funnel-shaped structure. After injecting a rated amount of water into the extraction bucket 1, the water is evenly distributed in the annular gap between the extraction bucket 1 and the annular filter plate 11, as well as in the inner ring of the annular filter plate 11, maintaining a consistent liquid level to ensure full immersion of the medicinal materials. Subsequently, the second linear actuator 121 drives the circular pressing plate 12, which is adapted to the diameter of the inner ring of the annular filter plate 11, to descend vertically, forming a counter-pressure force with the stationary receiving plate 13, fully squeezing out the effective juice from the medicinal materials. The squeezed medicinal material residue is retained in the annular filter plate 11, completing the extraction process.

[0064] After the drug extraction is completed, the main drug solution is first discharged directly through the drain port 17 at the bottom of the extraction tank 1, achieving preliminary separation of the drug solution and waste residue. During the extraction and discharge process, a small amount of drug solution will seep out from the gap between the receiving plate 13 and the annular filter plate 11. Guided by the lower half 133 of the receiving plate 13, the seeping drug solution drips through the inner ring of the discharge slope 2 into the collection shell 3. The water storage area at the bottom of the collection shell 3 is formed by the extension ring 32 and the collection shell 3 to store the seeping drug solution. It is then pumped back to the extraction tank 1 through the circulation pipe and water pump to avoid drug solution loss. At the same time, the raised flange 134 can prevent the drug solution from flowing freely on the lower end face of the receiving plate 13, ensuring that all the seeping drug solution flows into the water storage area. After both the main drug solution and the recovered drug solution have been discharged, the drug solution discharge process is completed.

[0065] After the liquid is drained, the first linear actuator 14 drives the receiving plate 13 and the second linear actuator 121 drives the pressing plate 12 to descend synchronously, so that the receiving plate 13 moves smoothly from the receiving position to the discharge position below the annular filter plate 11. At this time, the waste residue that has been squeezed into blocks is still between the pressing plate 12 and the receiving plate 13. Then the rotating unit 15 is started, and the rotating shaft 31 is driven to rotate by the cooperation of the gear ring 151, the gear 152 and the rotary actuator 153, which in turn drives the receiving plate 13 to rotate. During the rotation, the multiple protrusions 131 on the upper surface of the receiving plate 13 generate a pulling force on the blocky waste residue. At the same time, the pressing plate 12 continuously applies a pressing force under the action of the second linear actuator 121. The dual action promotes the rapid disintegration of the blocky waste residue. The disassembled waste residue is thrown out by the centrifugal force generated by the rotation of the receiving plate 13. Guided by the inner ring of the discharge slope 2, which is adapted to the diameter of the upper half 132 of the receiving plate 13, which is higher than the outer ring, it falls into the outer annular interception chamber 21 to avoid splashing. Subsequently, the first drive unit 24 drives the scraper 23 in the interception chamber 21 to rotate, pushing the accumulated waste residue to the discharge port 22 for centralized discharge. When the pressing plate 12 descends to the designated height, it begins to rise. When the pressing plate 12 is higher than the annular filter plate 11, the second drive unit 42 drives the through hole device 41 in the annular gap to start rotating, so that the ejector pin 411 is aligned with the filter hole of the annular filter plate 11. Air pressure drives the ejector pin 411 to extend and retract to clean the residual waste residue in the filter hole, realizing the self-cleaning of the filter plate. The cleaned waste residue falls on the receiving plate 13 and is thrown out by the centrifugal force generated by the receiving plate 13. After the slag discharge and hole cleaning are completed, the receiving plate 13 rises and resets to the receiving position, reserving feeding space for the next batch of extraction, and the cycle is repeated to complete continuous production.
