Description

Technical Field

[0001] This invention relates to the field of extraction device technology, specifically to a pollution-proof extraction device for traditional Chinese medicine formula granules and its usage method. Background Technology

[0002] Traditional Chinese medicine (TCM) granules refer to standardized granular or powdered preparations made from TCM decoction pieces that meet national standards, refined using modern pharmaceutical technologies (such as extraction, separation, concentration, and drying). Their properties, flavors, and efficacy are consistent with the original TCM decoction pieces. They do not require decoction and can be taken directly with warm water. They combine the characteristics of traditional Chinese medicine's syndrome differentiation and treatment and flexible compatibility with the advantages of modern preparations, such as convenient administration, precise dosage, controllable quality, and easy storage and transportation. They are an important supplement to TCM decoction pieces and are widely used in TCM clinical diagnosis and treatment as well as in daily family health care.

[0003] The extraction device for Chinese herbal medicine formula granules is the core equipment in the production process of Chinese herbal medicine formula granules. It specifically refers to a special pharmaceutical equipment that uses Chinese herbal medicine slices that meet national standards as raw materials, integrates functions such as extraction, stirring, temperature control, and filtration through a closed tank structure, and adopts appropriate processes such as water extraction and alcohol extraction to achieve efficient dissolution and separation of effective components of Chinese herbal medicine.

[0004] Among them, the water extraction method in the extraction process of traditional Chinese medicine formula granules uses purified water as the main solvent. Relying on the polar properties of water, it dissolves water-soluble active ingredients (such as alkaloid salts, flavonoids, etc.) containing polar groups such as hydroxyl, carboxyl, and amino groups in traditional Chinese medicine decoction pieces through hydrogen bonding and ionization. After the extraction tank completes the extraction of traditional Chinese medicine, the obtained traditional Chinese medicine extract needs to go through a standardized subsequent processing flow of "refining, concentration, drying, granulation and finished product quality control" in sequence to finally prepare traditional Chinese medicine formula granules.

[0005] Aqueous extracts contain viscous components such as polysaccharides, saponins, and tannins, which easily adhere to the inner walls of the device, pipes, and filter components, forming stubborn residues and causing cross-contamination in subsequent batches. Although cleaning with a scraping mechanism can achieve the desired removal effect, this mechanism is usually located inside the extraction tank, which is typically equipped with a stirring paddle to ensure uniform mixing of the liquid. The scraping mechanism needs to move close to the inner wall of the tank and pipes, which can easily cause interference in the spatial layout, leading to mechanical collisions or operational jamming. Therefore, to address the above problems, a contamination-proof traditional Chinese medicine formula granule extraction device and its usage method are proposed. Summary of the Invention

[0017] A method of using a pollution-resistant traditional Chinese medicine formula granule extraction device;

[0018] Step 1: When extracting Chinese herbal medicine granules, the Chinese herbal medicine pieces and water are put into the inside of the tank through the feed port. The cap is inserted into the feed port and fits against the inside of the second fluororubber ring. The cap is fixed to the cover plate with bolts. Hot air is delivered into the spiral groove through the hose and the connecting nozzle to heat the tank. The hot air flows out through the connecting nozzle at the top. The tank heats the Chinese herbal medicine pieces and water inside the tank through heat conduction. The second servo motor drives the insertion column to rotate. The transmission of the insertion column drives the central column to rotate. The central column rotates inside the cover plate through the first bearing and inside the end plate through the second bearing. The rotation of the central column drives the stirring arm assembly to rotate.

[0019] Step 2: During the replacement extraction, the first electric hydraulic cylinder drives the insert to disengage from the hexagonal slot, the first servo motor drives the shaft seat to rotate, the shaft seat drives the cover to rotate, and the tank rotates to 90 degrees. The second electric hydraulic cylinder is then activated to move the spiral rubber strip. The second electric hydraulic cylinder drives the second extraction tank assembly to slide towards the inside of the cover. The second extraction tank assembly moves the first extraction tank assembly through the positioning plate, and the tank disengages from the inside of the cover. The second extraction tank assembly enters the inside of the cover, and the outer surface of the second extraction tank assembly will fit against the inner side of the annular rubber ring and the spiral rubber strip. The cover rotates 90 degrees again, and the first electric hydraulic cylinder controls the insert to insert into the hexagonal slot of the second stirring assembly.

[0020] Step 3: When feeding the finished product after water extraction, close the solenoid valve connected to the second stirring component, open the solenoid valve connected to the sealing plate, remove the cover, and the force of gravity causes the stirring rod to rotate through the shaft inside the insert groove. The stirring rod is embedded inside the insert groove, and at the same time, the counterweight slides inside the slide groove. The counterweight is located at the lower end of the slide groove. The third permanent magnet block and the first permanent magnet block generate magnetic attraction. The extrusion of the stirring rod causes the water extract inside the insert groove to be squeezed out.

[0021] Step 4: When collecting the water extract from the inner wall of the tank, open the solenoid valve connected to the sealing plate and close the solenoid valve connected to the second stirring assembly. The bidirectional diaphragm air pump blows air into the tank through the three-way pipe and the solenoid valve. The central column slides inside the first bearing and the first fluororubber ring. The scraper ring scrapes off the water extract from the inner wall of the tank. The stirring arm assembly is stored inside the mounting groove. The water extract from the inner wall of the tank is separated from the inner wall of the tank. The compression of the end plate and the cover plate causes the water extract to flow out from the feed port.

[0022] Step 5: When cleaning the stirring mechanism and the inside of the tank, multiple stirring arm assemblies and the central column are located outside the tank. The scraper ring scrapes and cleans the inner wall of the tank. By pumping air through the bidirectional diaphragm air pump, negative pressure is generated inside the tank, causing the end plate to move away from the cover plate. The solvent flushes the space between the cover plate and the end plate.

[0023] Step Six: When the cleaned tank is used again, the tank is reset inside the cover with the tank facing upwards. The counterweight and the third permanent magnet block move downwards under gravity. At this time, the third permanent magnet block is aligned with the second permanent magnet block. The third permanent magnet block and the second permanent magnet block generate a magnetic repulsive force, and the stirring rod disengages from the insert groove.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this invention, by setting up a scraper ring, stirring arm assembly and central column, the device abandons the traditional built-in scraping solution in the tank. Through the design of a separable scraper ring and stirring assembly, the spatial interference problem between the scraping mechanism and the stirring paddle is avoided from the root, ensuring the stability of equipment operation and eliminating the risk of mechanical collision or jamming.

[0026] 2. In this invention, by setting up a first extraction tank assembly, a second extraction tank assembly and a first servo motor, the device adopts a dual extraction tank assembly alternating operation mode. When the main tank is performing material feeding and cleaning operations, the substitute tank can simultaneously carry out the extraction process without stopping the machine to wait, thereby achieving continuous production and significantly improving the overall production efficiency.

[0027] 3. In this invention, by setting up a bidirectional diaphragm air pump, end plate and scraper ring, the device can fully discharge the residual water extract in the gap of the stirring rod and thoroughly scrape off the stubborn liquid adhering to the inner wall of the tank through the air pressure assistance of the bidirectional diaphragm air pump during the feeding stage. This maximizes the water extract collection volume and reduces the waste of effective ingredients.

[0028] 4. In this invention, the stirring component can be completely separated from the tank and placed in the external environment by setting a central column, stirring arm assembly and bidirectional diaphragm air pump, realizing the visualization of the cleaning operation. This not only reduces the difficulty of the cleaning operation, but also deeply removes sticky residues, greatly improves the cleanliness of the equipment, and significantly reduces the risk of cross-contamination in subsequent batches from the process level.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0054] Please see Figures 1-16 The present invention provides a technical solution:

[0055] A pollution-resistant traditional Chinese medicine formula granule extraction device and its usage method include a support assembly 1 and a heating assembly 2. A first extraction tank assembly 3 is attached to the inner side of the heating assembly 2. A first stirring assembly 4 is installed inside the first extraction tank assembly 3. A suction blowing assembly 6 is fixedly connected to the lower end of the first extraction tank assembly 3. A positioning plate 5 and a second extraction tank assembly 7 are sequentially fixedly connected to the lower end of the first extraction tank assembly 3. A second stirring assembly 8 is installed inside the second extraction tank assembly 7. The first extraction tank assembly 3 includes a tank body 31. The first stirring assembly 4 includes a central column 41. A hexagonal groove 42 is opened at the upper end of the central column 41. An internal disc assembly 43 is installed at the lower end of the central column 41. An embedding groove 44 is opened at both the front and rear ends of the central column 41. A stirring arm assembly 47 is rotatably connected inside the embedding groove 44. The internal disc assembly 43 includes an end plate 431. A scraper ring 432 is fixedly connected to the end plate 431 by screws 434. The scraper ring 432 is embedded in the annular groove 433 opened in the end plate 431.

[0056] As a further implementation of this solution, the support assembly 1 includes a frame 11, with a frame plate 12 fixedly connected to the top of the frame 11. The front end of the frame 11 is fixedly connected to the housing of the first servo motor 13. The inner side of the frame plate 12 is fixedly connected to the cylinder body of the first electric hydraulic cylinder 14. A frame 15 is fixedly connected to the end of the piston rod of the first electric hydraulic cylinder 14. A guide post 16 is fixedly connected to the top of the frame 15, and the guide post 16 slides with the frame plate 12. The inner side of the frame 15 is fixedly connected to the housing of the second servo motor 17. The end of the motor 17 main shaft is fixedly connected to a plug 18. The plug 18 can be inserted into the hexagonal slot 42 by the drive of the first electric hydraulic cylinder 14. Through the above settings, the precise cooperation between the first electric hydraulic cylinder 14 and the guide column 16 realizes the stable insertion and removal of the plug 18 and the hexagonal slot 42, which not only ensures the reliable transmission of stirring power, but also allows for quick separation to meet the needs of alternating operation of the two tanks. The sliding limit design of the guide column 16 prevents the plug 18 from deviating, ensures precise docking with the hexagonal slot 42, reduces mechanical wear, and improves the stability of equipment operation.

[0057] As a further implementation of this solution, the heating component 2 includes a housing 21. A spiral groove 22 is provided on the inner side of the housing 21. Two connecting nozzles 23 are fixedly connected to the front end of the housing 21. The two connecting nozzles 23 are distributed at the upper and lower ends of the housing 21. The spiral groove 22 communicates with the inner side of the two connecting nozzles 23. The front end of the connecting nozzles 23 is fixed to the hose 27. An annular rubber ring 24 and a spiral rubber strip 25 are fixedly connected to the inner side of the housing 21. The inner side of the annular rubber ring 24 and the inner side of the spiral rubber strip 25 are both in contact with the outer side of the tank 31. Through the above settings, the spiral groove 22 makes the hot air form a spiral flow channel, extending the heat exchange path and realizing uniform heating of the tank 31. This avoids local temperature differences that cause degradation or uneven dissolution of effective ingredients. The double-fit design of the annular rubber ring 24 and the spiral rubber strip 25 not only ensures that the hot air is sealed and does not overflow to improve thermal efficiency, but also forms a stable limit on the tank 31, providing a precise positioning basis for switching extraction tanks.

[0058] As a further implementation of this solution, the right end of the cover 21 is fixedly connected to the cylinder body of the second electric hydraulic cylinder 29 via the first fixed seat. The piston rod end of the second electric hydraulic cylinder 29 is fixedly connected to the first ear seat. The left end of the cover 21 is fixedly connected to the cylinder body of the limiting telescopic rod 26 via the second fixed seat. The piston rod end of the limiting telescopic rod 26 is fixedly connected to the second ear seat. Both the first ear seat and the second ear seat are fixedly connected to the outer surface of the second extraction tank assembly 7 near the lower end. The front and rear ends of the cover 21 are fixedly connected to the bearing seat 28. The bearing seat 28 rotates with the frame 11. Through the above settings, the second electric hydraulic cylinder 29 provides a stable driving force. With the guidance and limiting of the limiting telescopic rod 26, the smooth sliding switching of the dual extraction tank assembly is realized, avoiding the displacement of the extraction tank during the switching process. This symmetrical drive structure ensures that the extraction tank is subjected to balanced force, reduces friction damage with the cover 21, ensures the continuity of alternating operations, and improves production efficiency.

[0059] As a further implementation of this solution, a toothed ring 32, a base plate 33, and a sealing plate 34 are fixedly connected to the inner side of the tank body 31. Spacing is provided between the toothed ring 32, the base plate 33, and the sealing plate 34. The bottom end of the sealing plate 34 is fixedly connected to the valve seat of the solenoid valve 35. A through hole on the inner side of the sealing plate 34 communicates with the valve port of the solenoid valve 35. The base plate 33 is fixedly connected to the positioning plate 5 by bolts. A first annular seat 37 and a fourth fluororubber ring 36 are sequentially fixedly connected to the top of the tank body 31. The base plate 33 is fixedly connected to the end cap assembly 38 by bolts. The first annular seat 37 and the second annular seat 387 are connected by the fourth fluororubber ring 36. The sealing is achieved by bolts between the first annular seat 37 and the second annular seat 387. The toothed ring 32 meshes with the toothed groove 435, which is located at the lower end of the end plate 431. Through the above arrangement, the meshing of the toothed ring 32 and the toothed groove 435 prevents the end plate 431 from rotating when the central column 41 rotates after it is installed inside the tank body 31, thus reducing the wear of the scraper ring 432. The fourth fluororubber ring 36 ensures a reliable seal at the top of the tank body 31, preventing leakage of the extract or external contamination. The integrated design of the solenoid valve 35 and the sealing plate 34 enables precise flow control for feeding and cleaning, avoiding cross-contamination caused by residual liquid.

[0060] As a further implementation of this solution, the end cap assembly 38 includes a cover plate 381. An internal hole 382 is formed on the inner side of the cover plate 381. A first bearing 383 and a first fluororubber ring 384 are fixedly connected inside the internal hole 382. A feed port 385 is formed on the inner side of the cover plate 381. A second fluororubber ring 386 is fixedly connected to the inner side of the feed port 385 near its lower end. The cover plate 381 is fixedly fitted with a second annular seat 387. A sealing cap 388 is fixedly connected to the upper end of the cover plate 381 by bolts. The outer side of the sealing cap 388 is fitted against the inner side of the second fluororubber ring 386. The first bearing 383... Both 83 and the first fluororubber ring 384 are sleeved on the outside of the central column 41. The inner side of the first bearing 383 and the inner side of the first fluororubber ring 384 are in contact with the outside of the central column 41. Through the above arrangement, the first bearing 383 reduces the frictional resistance of the rotation and sliding of the central column 41, the first fluororubber ring 384 achieves dynamic sealing to prevent the extract from overflowing from the gap, the tight fit between the second fluororubber ring 386 and the cap 388 ensures the sealing of the feeding and unloading process, and the large diameter design of the feed port 385 facilitates the feeding of medicinal slices and solvents, and can also improve the discharge efficiency of water extract and reduce residue.

[0061] As a further implementation of this solution, an extension groove 48 is provided on the central column 41 near the mounting groove 44. The first permanent magnet block 45 and the second permanent magnet block 46 are embedded in the inner side of the extension groove 48. The first permanent magnet block 45 and the second permanent magnet block 46 are fixedly engaged with the central column 41 by bolts. The outer side of the end plate 431 and the outer side of the scraper ring 432 are both in contact with the inner side of the tank body 31. The end plate 431 is rotatably connected to the central column 41 through the second bearing 436, and the end plate 431 and the central column 41 are sealed by the third fluororubber ring 437. Through the above settings, the magnetic attraction design of the double permanent magnet blocks realizes the automatic storage and unfolding of the stirring rod 471 without the need for an additional drive structure. This simplifies the operation and avoids interference between the stirring components and the scraper ring 432. The complete contact between the scraper ring 432 and the inner side of the tank body 31 ensures thorough scraping of residues. The third fluororubber ring 437 ensures the seal between the end plate 431 and the central column 41, preventing the liquid from seeping in and affecting the life of the equipment.

[0062] As a further implementation of this solution, the stirring arm assembly 47 includes a stirring rod 471. A shaft 473 is fixedly connected to the outer side of the stirring rod 471. The shaft 473 is rotatably connected to the inner side of the mounting groove 44. A sliding groove 472 is formed on the inner side of the stirring rod 471. The lower end of the stirring rod 471 is arc-shaped. A counterweight 474 is embedded in the inner side of the sliding groove 472. A gap is left between the outer side of the counterweight 474 and the sliding groove 472 formed by the stirring rod 471. A third permanent magnet block 475 is fixedly connected to the inner side of the counterweight block 474 by bolts. The magnetic attraction between the magnet 475 and the first permanent magnet 45, and the magnetic repulsion between the third permanent magnet 475 and the second permanent magnet 46, allow the arc-shaped stirring rod 471 to adhere to the tank wall for stirring, improving the uniformity of liquid mixing and accelerating the dissolution of active ingredients. The gap design between the counterweight 474 and the slide 472 avoids jamming caused by thermal expansion and contraction. Combined with the magnetic attraction principle, the stirring rod 471 can be reliably stored and unfolded, ensuring stirring efficiency and providing convenience for scraping operations and component removal, thus improving cleaning cleanliness.

[0063] As a further implementation of this solution, the extraction assembly 6 includes a vertical frame 61. The top end of the vertical frame 61 is fixedly engaged with the bottom end of the sealing plate 34, and the bottom end of the vertical frame 61 is fixedly engaged with the top end of the second extraction tank assembly 7. The vertical frame 61 is fixedly connected to the bidirectional diaphragm air pump 62 by bolts. A three-way pipe 63 is fixedly connected to the rear end of the flange interface of the bidirectional diaphragm air pump 62. The top end of the three-way pipe 63 is fixedly connected to the valve port at the lower end of the solenoid valve 35. The structure of the second extraction tank assembly 7 is the same as that of the first extraction tank assembly 3. The second extraction tank assembly 7 is connected to another solenoid valve. The valve port of 35 is fixedly connected to the bottom end of the three-way pipe 63. The structure of the second stirring component 8 is the same as that of the first stirring component 4. Through the above settings, the bidirectional diaphragm air pump 62, together with the three-way pipe 63 and the solenoid valve 35, can realize the alternating suction and blowing of air on the two tanks, thereby providing power support for the movement of the end plate 431, and thus improving the comprehensiveness of water extraction and extrusion. At the same time, this driving method does not require internal installation, which significantly reduces the space occupation. The end plate 431 fits inside the tank body 31, which can improve the stability of the end plate 431 when it moves.

[0064] Workflow: When extracting granules from a traditional Chinese medicine formula, remove the bolts connecting the cap 388 and the cover plate 381. Place the medicinal herbs and water into the tank 31 through the feed inlet 385. Insert the cap 388 into the feed inlet 385, ensuring it fits snugly against the inner side of the second fluororubber ring 386, thus sealing the inside of the tank 31. Secure the cap 388 to the cover plate 381 with bolts. Connect the hose 27 to the hot gas delivery pipe. Hot gas is delivered to the spiral groove 22 through the hose 27 and the connecting nozzle 23. The upper and lower annular rubber rings 24 prevent hot gas leakage. The spiral groove 22's opening shape and the spiral rubber strips 25's arrangement are both spiral structures, allowing hot gas to flow upwards through the spiral groove 22, thus heating the tank 31. The hot gas flows out through the upper connecting nozzle 23, and the tank 31 is heated through heat conduction. The internal Chinese herbal medicine slices and water are heated to achieve water extraction. During water extraction, the inside of the tank 31 needs to be stirred. At this time, the insert 18 is inserted into the hexagonal groove 42, driving the second servo motor 17 to rotate the insert 18. Through the transmission of the insert 18, the central column 41 is rotated. The central column 41 rotates inside the cover plate 381 through the first bearing 383 and inside the end plate 431 through the second bearing 436. The third fluororubber ring 437 can prevent the contents of the tank 31 from overflowing. When the central column 41 rotates, it will drive the rotating stirring arm assembly 47 to rotate. The stirring arm assembly 47 stirs the water and Chinese herbal medicine slices inside the tank 31, allowing the solvent to enter the cells more quickly, dissolving polar active ingredients such as polysaccharides, flavonoids, and saponins, shortening the extraction cycle. After water extraction, the state of the Chinese herbal medicine slices is mainly sedimentation, with a small number of special slices floating slightly.

[0065] During replacement retrieval, the first electric hydraulic cylinder 14 is activated, driving the frame 15, guide column 16, second servo motor 17, and insert column 18 upwards. The guide column 16 slides inside the frame plate 12, thereby disengaging the insert column 18 from the hexagonal slot 42 and leaving a gap between the insert column 18 and the hexagonal slot 42 for the tank body 31 to rotate. At this time, the first servo motor 13 is activated, driving the bearing seat 28 to rotate. The bearing seats 28 at both ends are rotated with the frame 11 through the bearing column 473. The bearing seats 28 drive the cover 21 to rotate. The soft material of the hose 27 does not affect the normal rotation of the cover 21. The internal structure of the tank body 31 rotates simultaneously. After rotating to ninety degrees, the second electric hydraulic cylinder 29 is activated, driving the spiral rubber strip 25 to move. The contraction of 9 causes the second extraction tank assembly 7 to slide towards the inside of the cover 21. The second extraction tank assembly 7 drives the first extraction tank assembly 3 to move through the positioning plate 5. At this time, the first extraction tank assembly 3 disengages from the inside of the cover 21, while the second extraction tank assembly 7 enters the inside of the cover 21. The outer surface of the second extraction tank assembly 7 will fit against the inner side of the annular rubber ring 24 and the spiral rubber strip 25. At this time, the first servo motor 13 is controlled to rotate the cover 21 ninety degrees again, so that the hexagonal groove 42 of the second stirring assembly 8 faces the insertion post 18. The first electric hydraulic cylinder 14 controls the insertion post 18 to insert into the hexagonal groove 42 of the second stirring assembly 8. At the same time, the feeding and water extraction are carried out through the above principle. This method can realize continuous water extraction and improve production efficiency.

[0066] When discharging the finished product after water extraction, close the solenoid valve 35 connected to the second stirring assembly 8, open the solenoid valve 35 connected to the sealing plate 34, align the receiving cylinder with the sealing cover 388, remove the sealing cover 388, and let the water extract and mixture inside the tank 31 flow into the receiving cylinder. At the same time, after the first stirring assembly 4 is facing downward relative to the second stirring assembly 8, under the action of gravity, the stirring rod 471 rotates through the shaft 473 inside the insert groove 44, and the stirring rod 471 is embedded inside the insert groove 44. At the same time, the counterweight 474 slides inside the slide groove 472. The distance between the counterweight 474 and the inner side of the slide groove 472 can prevent the stirring rod 471 from getting stuck between the stirring rod 471 and the counterweight 474 due to thermal expansion and contraction. The counterweight 474 slides to the lower end of the slide groove 472. The third permanent magnet block 475 and the first permanent magnet block 475... When the magnet 45 approaches, the third permanent magnet 475 and the first permanent magnet 45 are magnetically attracted to each other. The magnetic attraction design allows the stirring rod 471 to be pressed tightly against the inside of the insert 44. The water extract inside the insert 44 is squeezed out by the extrusion of the stirring rod 471. The first permanent magnet 45, the second permanent magnet 46 and the third permanent magnet 475 are all made of samarium cobalt magnets, which have extremely high temperature resistance and no significant magnetic decay after long-term use in the high-temperature environment of the extraction tank. The stirring rod 471 is made of austenitic stainless steel, which contains only very weak residual magnetism and the magnetic attraction reaction is not obvious, ensuring the effectiveness of the magnetism and the effectiveness of storing the stirring rod 471 inside the insert 44. The stirring rod 471 being located inside the insert 44 also makes it easy for the insert 44 and the stirring arm assembly 47 to be removed from the tank 31, thereby increasing the water extract collection volume.

[0067] When collecting the aqueous extract from the inner wall of tank 31, the solenoid valve 35 connected to the sealing plate 34 is opened, and the solenoid valve 35 connected to the second stirring assembly 8 is closed. The bidirectional diaphragm air pump 62 is started to blow air into the tank 31 through the three-way pipe 63 and the solenoid valve 35. Under the action of gas pressure and the gravity of the first stirring assembly 4, the central column 41 slides inside the first bearing 383 and the first fluororubber ring 384. The seal of the first fluororubber ring 384 can prevent the mixture from overflowing. At the same time, when the end plate 431 and the scraper ring 432 move, the aqueous extract on the inner wall of tank 31 is scraped off by the scraper ring 432. 432 is made of fluororubber, which is resistant to high temperature, corrosion and food grade. Since the stirring arm assembly 47 is housed inside the mounting groove 44, it does not hinder the normal movement of the central column 41. At this time, the water extract can be separated from the inner wall of the tank 31. When the end plate 431 is about to approach the cover plate 381, the water extract can be squeezed out from the feed port 385 by the end plate 431 and the cover plate 381, which further increases the amount of water extract collected. This changes the traditional practice of setting a scraping mechanism inside the extraction tank, prevents the scraping mechanism from interfering with the stirring mechanism in terms of spatial arrangement, and ensures the safe operation of the stirring mechanism.

[0068] During the cleaning of the stirring mechanism and the inside of the tank 31, after the central column 41 is detached from the inside of the tank 31, the multiple stirring arm assemblies 47 and the central column 41 are located outside the tank 31, making the cleaning of the stirring mechanism visible and convenient. At the same time, the scraper ring 432 scrapes and cleans the inner wall of the tank 31, reducing the difficulty of cleaning. After the air is pumped by the bidirectional diaphragm air pump 62, the negative pressure is generated inside the tank 31, causing the end plate 431 to move away from the cover plate 381. Then, the space between the cover plate 381 and the end plate 431 is rinsed with solvent. The solvent is a mixture of pharmaceutical ethanol and purified water in a volume ratio of 7:3 or 8:2. The mixture is heated to 40℃-60℃ at room temperature or at room temperature. Afterward, the space between the cover plate 381 and the end plate 431 is rinsed with purified water to improve the cleanliness of the inside of the tank 31 and prevent cross-contamination in subsequent batches.

[0069] When the cleaned tank 31 is used again, the same principle applies. The tank 31 is returned to the inside of the cover 21 with the tank 31 facing upward. During this period, if the stirring rod 471 is inside the mounting groove 44 and has not disengaged, the counterweight 474 and the third permanent magnet block 475 move downward under gravity. At this time, the third permanent magnet block 475 aligns with the second permanent magnet block 46. The third permanent magnet block 475 and the second permanent magnet block 46 generate a magnetic repulsive force, thereby causing the stirring rod 471 to disengage from the mounting groove 44, ensuring that the stirring rod 471 can effectively stir.

The method of using the pollution-resistant traditional Chinese medicine formula granule extraction device according to claim 6, characterized in that: Step 1: When extracting Chinese herbal medicine granules, the Chinese herbal medicine pieces and water are put into the inside of the tank through the feed port. The cap is inserted into the feed port and fits against the inside of the second fluororubber ring. The cap is fixed to the cover plate with bolts. Hot air is delivered into the spiral groove through the hose and the connecting nozzle to heat the tank. The hot air flows out through the connecting nozzle at the top. The tank heats the Chinese herbal medicine pieces and water inside the tank through heat conduction. The second servo motor drives the insertion column to rotate. The transmission of the insertion column drives the central column to rotate. The central column rotates inside the cover plate through the first bearing and inside the end plate through the second bearing. The rotation of the central column drives the stirring arm assembly to rotate. Step 2: During the replacement extraction, the first electric hydraulic cylinder drives the insert to disengage from the hexagonal slot, the first servo motor drives the shaft seat to rotate, the shaft seat drives the cover to rotate, and the tank rotates to 90 degrees. The second electric hydraulic cylinder is then activated to move the spiral rubber strip. The second electric hydraulic cylinder drives the second extraction tank assembly to slide towards the inside of the cover. The second extraction tank assembly moves the first extraction tank assembly through the positioning plate, and the tank disengages from the inside of the cover. The second extraction tank assembly enters the inside of the cover, and the outer surface of the second extraction tank assembly will fit against the inner side of the annular rubber ring and the spiral rubber strip. The cover rotates 90 degrees again, and the first electric hydraulic cylinder controls the insert to insert into the hexagonal slot of the second stirring assembly. Step 3: When feeding the finished product after water extraction, close the solenoid valve connected to the second stirring component, open the solenoid valve connected to the sealing plate, remove the cover, and the force of gravity causes the stirring rod to rotate through the shaft inside the insert groove. The stirring rod is embedded inside the insert groove, and at the same time, the counterweight slides inside the slide groove. The counterweight is located at the lower end of the slide groove. The third permanent magnet block and the first permanent magnet block generate magnetic attraction. The extrusion of the stirring rod causes the water extract inside the insert groove to be squeezed out. Step 4: When collecting the water extract from the inner wall of the tank, open the solenoid valve connected to the sealing plate and close the solenoid valve connected to the second stirring assembly. The bidirectional diaphragm air pump blows air into the tank through the three-way pipe and the solenoid valve. The central column slides inside the first bearing and the first fluororubber ring. The scraper ring scrapes off the water extract from the inner wall of the tank. The stirring arm assembly is stored inside the mounting groove. The water extract from the inner wall of the tank is separated from the inner wall of the tank. The compression of the end plate and the cover plate causes the water extract to flow out from the feed port. Step 5: When cleaning the stirring mechanism and the inside of the tank, multiple stirring arm assemblies and the central column are located outside the tank. The scraper ring scrapes and cleans the inner wall of the tank. By pumping air through the bidirectional diaphragm air pump, negative pressure is generated inside the tank, causing the end plate to move away from the cover plate. The solvent flushes the space between the cover plate and the end plate. Step Six: When the cleaned tank is used again, the tank is reset inside the cover with the tank facing upwards. The counterweight and the third permanent magnet block move downwards under gravity. At this time, the third permanent magnet block is aligned with the second permanent magnet block.
