Description

Technical Field

[0001] This application relates to the technical field of pharmaceutical equipment for traditional Chinese medicine, and in particular to an integrated extraction and separation device for traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine polysaccharides are a class of natural macromolecular compounds with important biological activities and wide applications, mainly concentrated in the fields of medicine and health. They can be used directly in drug development as immunomodulators, adjuvant antitumor drugs, and antioxidants, and can also be used as functional ingredients in health products and nutritional supplements to regulate blood sugar and lipids and improve gut health.

[0003] The extraction and separation of polysaccharides from traditional Chinese medicine typically relies on dispersed, individual equipment. During operation, technicians must sequentially use multiple independent devices, such as extraction tanks, filtration equipment, decolorization devices, concentration equipment, and alcohol precipitation tanks, repeatedly transferring materials between each step.

[0004] Regarding the aforementioned technologies, if a decentralized equipment layout is adopted during the extraction and separation process, multiple material transfer and connection operations are required between each piece of equipment before proceeding to the next step. This process is cumbersome and carries a high risk of material exposure, resulting in poor process continuity and low extraction efficiency. Summary of the Invention

[0005] To improve the continuity of the process and the extraction efficiency, this application provides an integrated traditional Chinese medicine extraction and separation device.

[0006] The integrated traditional Chinese medicine extraction and separation device provided in this application adopts the following technical solution: An integrated traditional Chinese medicine extraction and separation device includes an extraction tank, a stirring assembly for stirring raw materials inside the extraction tank, a connecting port at the bottom of the extraction tank connected to a first pipe, a fine filter at the bottom of the extraction tank, a decolorizing column filled with adsorbent material on one side of the fine filter, a second pipe fixedly connected between the decolorizing column and the fine filter, a low-temperature concentrator on one side of the decolorizing column, a third pipe connected between the decolorizing column and the low-temperature concentrator, a liquid preparation and storage tank for preparing or storing ethanol solution on one side of the low-temperature concentrator, a fourth pipe fixedly connected between the liquid preparation and storage tank and the low-temperature concentrator, a fifth pipe connected to the fourth pipe, a fifth pipe connected to the extraction tank at the end away from the fourth pipe, a discharge port on one side of the extraction tank, and a pushing assembly at the bottom of the extraction tank for pushing precipitates towards the discharge port.

[0007] By adopting the above technical solution, the extraction tank is used for the preliminary extraction of Chinese herbal medicine raw materials. The stirring component can fully mix the raw materials and solvent, improving extraction efficiency. The extract enters the fine filter through the connecting port and the first pipe for precision filtration to remove large particulate impurities. Subsequently, the filtrate enters the decolorization column through the second pipe, where the adsorbent material removes pigments and small molecule impurities. The decolorized liquid enters the low-temperature concentrator through the third pipe for concentration, reducing the solvent volume. The concentrated liquid and ethanol entering the integrated liquid preparation and storage tank flow synchronously to the fourth pipe for mixing, and then flow back to the extraction tank through the fifth pipe for static precipitation. The precipitate is the desired Chinese herbal medicine polysaccharide. The discharge port works in conjunction with the pushing component to facilitate the discharge of the extracted precipitate. The entire device achieves continuous operation through the piping system, reducing material transfer and exposure, and significantly improving process continuity and extraction efficiency.

[0008] Optionally, a drive motor is fixedly installed on the top of the extraction tank, and the stirring assembly includes a stirring rod and stirring blades. The stirring rod is vertically arranged, and its upper end passes through the top of the extraction tank and is rotatably connected to the extraction tank. The output shaft of the drive motor is fixedly connected to the upper end of the stirring rod, and a plurality of stirring blades are evenly distributed around the stirring rod and fixedly connected to the stirring rod.

[0009] By adopting the above technical solution, the drive motor provides power to rotate the stirring rod and stirring blades, thereby achieving uniform stirring of the materials in the tank, promoting the dissolution of effective components, and improving extraction efficiency.

[0010] Optionally, both the third and fifth pipelines are equipped with infusion pumps and metering valves.

[0011] By adopting the above technical solutions, the infusion pump provides the power for liquid delivery, and the metering valve accurately controls the liquid flow rate and direction, which facilitates process adjustment and automated control.

[0012] Optionally, the extraction tank is equipped with a filter screen at the connection port.

[0013] By adopting the above technical solutions, the filter screen can initially intercept large particles of residue, prevent blockage of pipelines and subsequent equipment, and extend the service life of the device.

[0014] Optionally, the extraction tank has a sealing plate embedded in the communication port for sealing the communication port, the filter screen is located between the sealing plate and the first pipe, and the extraction tank is provided with a moving component for moving the sealing plate.

[0015] By adopting the above technical solution, the sealing plate can seal the connection port during mixing of materials, preventing liquid leakage. The movable component facilitates quick opening and closing of the sealing plate, improving operational convenience.

[0016] Optionally, a fixing block is fixedly provided on one side of the extraction tank. The fixing block has a cavity inside. The moving component includes a rotating rod and a handwheel. One end of the rotating rod is fixedly connected to the edge of the sealing plate. The other end of the rotating rod passes through the side wall of the extraction tank and the fixing block in sequence and passes through the cavity. The rotating rod is slidably connected to the fixing block. The handwheel is fixedly connected to the end of the rotating rod away from the sealing plate. The fixing block has a first fixing groove on the side wall of the cavity away from the extraction tank. The side wall of the rotating rod is fixedly provided with a fixing protrusion that slides and adapts to the first fixing groove.

[0017] By adopting the above technical solution, when releasing the seal, first push the handwheel towards the extraction tank. The handwheel drives the rotating rod to move, and the rotating rod moves the fixed protrusion into the cavity. Then, by rotating the handwheel, the rotating rod is moved, thereby opening the sealing plate. The fixed protrusion cooperates with the first fixing groove to achieve temporary fixation in the closed position and prevent accidental operation.

[0018] Optionally, the fixing block may also have a second fixing groove on the side wall of the cavity away from the extraction tank. The second fixing groove is disposed opposite to the first fixing groove, and the fixing protrusion is slidably adapted to the second fixing groove.

[0019] By adopting the above technical solution, after the sealing plate releases the blockage of the communication port, the fixed protrusion and the second fixed groove are aligned. The handwheel is moved away from the extraction tank, and the handwheel drives the rotating rod and the fixed protrusion to move. The fixed protrusion slides into the second fixed groove to fix the rotating rod, making it difficult for the sealing plate to drive the rotating rod to rotate.

[0020] Optionally, a support plate is fixedly installed on the side of the extraction tank away from the discharge port. The pushing assembly includes a drive cylinder and a push plate. The drive cylinder is fixedly installed on the support plate. The push plate is installed inside the extraction tank and perpendicular to the bottom wall of the extraction tank. The output shaft of the drive cylinder passes through the side wall of the extraction tank and is fixedly connected to the push plate. A sealing plate is provided at the discharge port of the extraction tank. A driving assembly for driving the sealing plate to move is provided on the extraction tank.

[0021] By adopting the above technical solution, the drive cylinder pushes the pusher plate to push the sediment towards the discharge port, realizing automatic discharge. The sealing plate works in conjunction with the drive assembly to control the opening and closing of the discharge port and prevent liquid leakage.

[0022] Optionally, a push rod is fixedly installed on the side of the push plate facing the discharge port, the push rod is perpendicular to the push plate, a horizontal support plate is fixedly installed on the extraction tank at the discharge port, an auxiliary plate is fixedly installed on the side of the support plate away from the extraction tank, the auxiliary plate is parallel to the sealing plate, and the driving assembly includes a telescopic rod and a spring, both of which are fixedly installed between the auxiliary plate and the sealing plate, with the spring sleeved on the outside of the telescopic rod.

[0023] By adopting the above technical solution, when the push plate moves, the push rod can push the sealing plate to move away from the discharge port, automatically opening the discharge port. The sediment is discharged through the discharge port as the push plate moves, realizing automatic cleaning of the sediment. After discharge, the spring resets and pushes the sealing plate to close the discharge port. The telescopic rod plays a guiding role, ensuring the smoothness and sealing of the sealing plate movement. The structure is compact and requires no additional manual operation, further improving the convenience of operation.

[0024] Optionally, a clearance groove is provided through one end of the support plate near the extraction tank, and a collection shell is connected to the support plate at the clearance groove. The collection shell is located below the support plate, and baffles are fixedly provided on both opposite sides of the support plate.

[0025] By adopting the above technical solutions, the clearance trough facilitates the smooth flow of sediment from the extraction tank into the collection shell, preventing it from accumulating on the support plate; the collection shell can collect the sediment in a concentrated manner, facilitating subsequent processing; and the baffle can prevent the sediment from scattering to both sides during discharge, ensuring a clean working environment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The integrated design combines multiple processes into one, with closed material transport, eliminating the need for multiple manual transfers, greatly improving process continuity, reducing material exposure risks and operational intensity, and significantly improving extraction efficiency; 2.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses an integrated traditional Chinese medicine extraction and separation device.

[0031] refer to Figure 1 The integrated traditional Chinese medicine extraction and separation device includes an extraction tank 1, which is made of stainless steel. A drive motor 13 is bolted to the top of the extraction tank 1, and the output shaft of the drive motor 13 extends vertically downward into the interior of the extraction tank 1 and is rotatably connected to the top of the extraction tank 1. A conveying pipe 19 for conveying raw materials into the extraction tank 1 is fixed to one side of the upper end of the extraction tank 1.

[0032] refer to Figure 1 and Figure 2 The extraction tank 1 is equipped with a stirring assembly 2 for stirring raw materials. The stirring assembly 2 includes a stirring rod 21 and stirring blades 22. The stirring rod 21 is vertically arranged, and the upper end of the stirring rod 21 is fixedly connected to the output shaft of the drive motor 13. Four stirring blades 22 are evenly welded on the periphery of the stirring rod 21. The stirring blades 22 have an arc-shaped structure, which can enhance the material disturbance effect during stirring.

[0033] After the drive motor 13 starts, the output shaft drives the stirring rod 21 to rotate at high speed. The stirring blades 22 rotate synchronously with the stirring rod 21, thoroughly stirring the Chinese herbal raw materials and solvent in the extraction tank 1. During the stirring process, the arc-shaped stirring blades 22 continuously cut and turn the material, breaking the solvent boundary layer on the surface of the raw material particles, allowing the raw materials and solvent to mix quickly and evenly. This accelerates the dissolution of effective components such as polysaccharides from the raw material cells into the solvent, thereby significantly improving the extraction efficiency. At the same time, the high-speed rotation of the stirring blades 22 also prevents the raw materials from accumulating at the bottom of the tank, ensuring that the raw materials in all areas of the tank receive the same degree of stirring treatment, thus guaranteeing the consistency of the extraction effect.

[0034] refer to Figure 1 , Figure 2 and Figure 3 The extraction tank 1 has a connecting port 11 at its bottom. A sealing plate 15, made of metal, is embedded in the connecting port 11 to seal it. The sealing plate 15 fits snugly against the inner wall of the connecting port 11, providing a seal. A filter screen 14, made of stainless steel woven mesh with a mesh size of 80, is also installed at the connecting port 11 to intercept large particles of residue from the raw material. A first pipe 31 is fixedly installed at the connecting port 11 in the extraction tank 1. The filter screen 14 is located between the sealing plate 15 and the subsequently connected first pipe 31 to prevent residue from entering the pipe and causing blockage.

[0035] During the extraction process, the sealing plate 15 is closed, tightly fitting against the inner wall of the connecting port 11 to prevent liquid in the extraction tank 1 from leaking out of the connecting port 11 during stirring, ensuring the airtightness of the extraction environment. After extraction is complete, the sealing plate 15 is opened, and the extract flows towards the connecting port 11 under gravity. When passing through the filter screen 14, large particles of raw material residue are intercepted on the filter screen 14, while the extract containing effective components smoothly passes through the filter screen 14 and enters the first pipe 31. This method of filtering before conveying effectively avoids large particles of impurities from entering subsequent fine filters 3, pipes, and other equipment, reducing the risk of equipment blockage and extending the service life of the entire device.

[0036] refer to Figure 1 , Figure 2 and Figure 4 A fixing block 7 is welded to one side of the extraction tank 1. The fixing block 7 has a cavity 71 inside. A moving assembly 6 for moving the sealing plate 15 is installed at the fixing block 7. The moving assembly 6 includes a rotating rod 61 and a handwheel 62. One end of the rotating rod 61 is welded and fixed to the edge of the sealing plate 15. The other end of the rotating rod 61 passes through the side wall of the extraction tank 1 and the fixing block 7, and then through the cavity 71. The rotating rod 61 is slidably connected to the fixing block 7 and is sealed to the side wall of the extraction tank 1 to prevent leakage. The handwheel 62 is welded and fixed to the end of the rotating rod 61 away from the sealing plate 15. The handwheel 62 has anti-slip textures on its circumference for easy gripping and rotation by the operator.

[0037] The fixing block 7 has a first fixing groove 73 and a second fixing groove 74 on the side wall of the cavity 71 away from the extraction tank 1. The first fixing groove 73 and the second fixing groove 74 are arranged opposite to each other and are both arc-shaped grooves. The side wall of the rotating rod 61 is welded with a fixing protrusion 72. The fixing protrusion 72 is an arc-shaped block and is slidably adapted to both the first fixing groove 73 and the second fixing groove 74.

[0038] When it is necessary to open the sealing plate 15, the operator holds the handwheel 62 with anti-slip texture and applies a pushing force towards the extraction tank 1. The handwheel 62 drives the rotating rod 61 to slide along its own axis towards one side of the extraction tank 1. Simultaneously, the rotating rod 61 drives the fixed protrusion 72 welded to the side wall to disengage from the first fixed groove 73 and gradually enter the cavity 71 inside the fixed block 7. At this time, the contact between the sealing plate 15 and the inner wall of the connecting port 11 is released, and the rotating rod 61 loses the limiting constraint of the first fixed groove 73. Subsequently, the operator rotates the handwheel 62, which transmits torque through the rotating rod 61, causing the sealing plate 15 to rotate around the axis of the rotating rod 61, so that the sealing plate 15 gradually deviates from the orthographic projection area of ​​the connecting port 11 until the connecting port 11 is fully opened, facilitating the smooth flow of the extract.

[0039] After the sealing plate 15 is fully opened, the operator turns the handwheel 62 to adjust the angle of the rotating rod 61 so that the fixed protrusion 72 is aligned with the position of the second fixing groove 74. Then, the operator pulls the handwheel 62 away from the extraction tank 1. The rotating rod 61 drives the fixed protrusion 72 to slide into the second fixing groove 74. The second fixing groove 74 limits and fixes the fixed protrusion 72, preventing the sealing plate 15 from rotating due to liquid impact or equipment vibration during the flow of the extraction liquid, and ensuring that the connection port 11 always remains unobstructed.

[0040] refer to Figure 1 The first pipe 31, at the end furthest from the connecting port 11, is connected to the fine filter 3. The fine filter 3 uses a ceramic membrane filter with a filtration accuracy of 0.1μm, which can further remove fine impurities in the extract. A second pipe 33 is connected to one side of the fine filter 3. The end of the second pipe 33 furthest from the fine filter 3 is connected to a decolorizing column 32. The decolorizing column 32 is filled with activated carbon adsorption material, which can adsorb pigments and small molecule impurities in the extract, achieving decolorization and purification. A third pipe 35 is connected to the other side of the decolorizing column 32. The end of the third pipe 35 furthest from the decolorizing column 32 is connected to a low-temperature concentrator 34. The low-temperature concentrator 34 uses vacuum low-temperature concentration technology, with the concentration temperature controlled at 40-60℃, which can lower the boiling point of the solvent while preventing the active ingredients such as polysaccharides from deteriorating due to high temperatures.

[0041] After the extract enters the fine filter 3 through the first pipe 31, it passes through the ceramic membrane filter element under the action of pressure difference. Fine impurities in the extract that were not intercepted by the filter screen 14 are retained by the ceramic membrane, thus achieving precise filtration of the extract and obtaining a clear filtrate. The clear filtrate flows into the decolorization column 32 through the second pipe 33. The activated carbon adsorbent material in the decolorization column 32 has a large specific surface area and strong adsorption capacity, which can quickly adsorb small molecule impurities such as pigments and tannins in the filtrate, making the filtrate lighter in color and improving the purity of the product. The decolorized filtrate enters the low-temperature concentrator 34 through the third pipe 35. Under vacuum, the boiling point of the solvent decreases, and it can evaporate rapidly at a low temperature of 40-60℃, thereby reducing the solvent volume and increasing the concentration of effective components in the filtrate. At the same time, the low-temperature environment effectively avoids the denaturation and decomposition of heat-sensitive effective components such as polysaccharides in traditional Chinese medicine due to high temperatures, ensuring the bioactivity and quality of the product.

[0042] refer to Figure 1 A liquid preparation and storage tank 36 is installed on one side of the low-temperature concentrator 34. The liquid preparation and storage tank 36 is used to prepare and store ethanol solutions. A fourth pipe 37 connects the liquid preparation and storage tank 36 and the low-temperature concentrator 34. A fifth pipe 38 is branched off the fourth pipe 37. The end of the fifth pipe 38 away from the fourth pipe 37 is connected to the top of the extraction tank 1. Both the third pipe 35 and the fifth pipe 38 are equipped with a liquid delivery pump 5 and a metering valve 51. The liquid delivery pump 5 is a stainless steel centrifugal pump that provides power for liquid delivery. The metering valve 51 is an electromagnetic metering valve that can accurately control the flow rate and delivery volume of the liquid, facilitating automated process control.

[0043] After the concentration process is completed, the infusion pump 5 on the third pipeline 35 is started to transport the concentrated extract to the fourth pipeline 37. Simultaneously, the prepared ethanol solution in the integrated liquid preparation and storage tank 36 also flows into the fourth pipeline 37, where it mixes thoroughly with the concentrated extract to form an alcohol precipitation system. At this point, the metering valve 51 on the fifth pipeline 38 precisely controls the flow rate of the mixture according to process requirements, and the infusion pump 5 provides power to transport the mixture back to the extraction tank 1 through the fifth pipeline 38. The entire liquid transport process is powered by the infusion pump 5 to ensure smooth liquid flow, while the metering valve 51 enables precise control of the liquid flow rate. This allows operators to adjust the liquid delivery volume according to factors such as raw material type and extraction process, ensuring the alcohol precipitation effect and also providing the possibility for automated process control.

[0044] refer to Figure 1 and Figure 2A rectangular discharge port 12 is provided on one side of the extraction tank 1. A support plate 16 is welded to the side of the extraction tank 1 away from the discharge port 12. A pushing assembly 4 for pushing the sediment toward the discharge port 12 is provided on the support plate 16. The pushing assembly 4 includes a drive cylinder 41 and a push plate 42. The drive cylinder 41 and the support plate 16 are fixedly connected. The push plate 42 is disposed inside the extraction tank 1 and is perpendicular to the bottom wall of the extraction tank 1. The output shaft of the drive cylinder 41 passes through the side wall of the extraction tank 1 and extends into the extraction tank 1 and is fixedly connected to the push plate 42. Two push rods 18 are welded to the side of the push plate 42 facing the discharge port 12. The push rods 18 are perpendicular to the push plate 42 to enhance the pushing effect.

[0045] After the mixture has settled and precipitated in the extraction tank 1, the effective components such as polysaccharides from the traditional Chinese medicine form precipitates that settle at the bottom of the extraction tank 1. At this time, the drive cylinder 41 is activated, and its output shaft extends, pushing the pusher plate 42 towards the discharge port 12. During the movement, the bottom of the pusher plate 42 is in close contact with the bottom wall of the extraction tank 1, pushing the precipitates deposited at the bottom forward. The push rod 18 on the pusher plate 42 further enhances the pushing effect on the precipitates, preventing the precipitates from accumulating in front of the pusher plate 42 and ensuring that the precipitates can be smoothly pushed to the discharge port 12. The drive cylinder 41 enables automatic pushing of the precipitates, eliminating the need for manual cleaning, reducing the labor intensity of operators, and improving discharge efficiency.

[0046] refer to Figure 1 and Figure 2 The extraction tank 1 has a sealing plate 17 at the discharge port 12. The sealing plate 17 is a rectangular metal plate that fits against the edge of the discharge port 12. A horizontal support plate 9 is welded to the discharge port 12 of the extraction tank 1. An auxiliary plate 91 is welded to the side of the support plate 9 away from the extraction tank 1. The auxiliary plate 91 is parallel to the sealing plate 17. A driving assembly 8 is provided between the auxiliary plate 91 and the sealing plate 17. The driving assembly 8 includes a telescopic rod 81 and a spring 82. There are two telescopic rods 81 and two springs 82, which are evenly distributed between the auxiliary plate 91 and the sealing plate 17. The two ends of the telescopic rod 81 are welded and fixed to the auxiliary plate 91 and the sealing plate 17, respectively. The spring 82 is sleeved on the outside of the telescopic rod 81. The two ends of the spring 82 are also welded and fixed to the auxiliary plate 91 and the sealing plate 17, respectively. The spring 82 is always in a compressed state.

[0047] As the push plate 42 moves toward the discharge port 12, the push rod 18 on the push plate 42 first contacts the sealing plate 17 and applies a pushing force. As the push plate 42 continues to move, the pushing force gradually increases, overcoming the compression force of the spring 82 and pushing the sealing plate 17 away from the discharge port 12, thus automatically opening the discharge port 12. The sediment, pushed by the push plate 42, is discharged through the discharge port 12 and falls onto the support plate 9. After discharge is complete, the output shaft of the drive cylinder 41 retracts, causing the push plate 42 and push rod 18 to reset away from the discharge port 12. At this time, the compression force of the spring 82 is released, pushing the sealing plate 17 toward the discharge port 12 until the sealing plate 17 is in contact with the edge of the discharge port 12, thus automatically closing the discharge port 12. The telescopic rod 81 acts as a guide during the movement of the sealing plate 17, ensuring that the sealing plate 17 can reset smoothly and accurately, guaranteeing the sealing seal and preventing leakage of liquid from the extraction tank 1 in subsequent operations.

[0048] refer to Figure 1 and Figure 2 A rectangular clearance groove 92 is provided through one end of the support plate 9 near the extraction tank 1. A collection shell 93 is bolted to the support plate 9 at the clearance groove 92. The collection shell 93 is located below the support plate 9 to facilitate the collection of sediment. Baffles 94 are welded to opposite sides of the support plate 9. The baffles 94 are vertically arranged to prevent sediment from scattering to both sides during discharge.

[0049] After the sediment discharged from the discharge port 12 falls onto the support plate 9, it is continuously pushed by the pusher plate 42 and moves along the support plate 9 towards the clearance groove 92, eventually falling into the collection shell 93 below through the clearance groove 92. The baffles 94 on both sides of the support plate 9 can prevent the sediment from scattering to both sides, avoiding material waste and pollution of the working environment. At the same time, they can also guide the sediment towards the clearance groove 92, ensuring that the sediment can fall smoothly into the collection shell 93.

[0050] The implementation principle of the integrated traditional Chinese medicine extraction and separation device in this application embodiment is as follows: First, the traditional Chinese medicine raw materials and solvent are added to the extraction tank 1, and the drive motor 13 is started. The materials are stirred and extracted by the stirring component 2. After extraction, the moving component 6 is operated to open the sealing plate 15. The extract is initially filtered through the filter screen 14, and then enters the fine filter 3 through the first pipe 31 for fine filtration. Then, it enters the decolorization column 32 through the second pipe 33 for decolorization, and then enters the low-temperature concentrator 34 through the third pipe 35 for concentration. After the concentrated liquid is mixed with the ethanol solution in the liquid preparation and storage tank 36, it is returned to the extraction tank 1 through the fifth pipe 38 for static precipitation. After precipitation, the drive cylinder 41 is started, and the precipitate is pushed into the collection shell 93 through the discharge port 12 by the pushing component 4. The entire process realizes closed material transmission through the pipeline system, eliminating the need for multiple manual transfers, which significantly improves the continuity of the process and the extraction efficiency. At the same time, the coordinated cooperation of each component ensures product quality and ease of operation.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
