Description

Technical Field

[0001] This invention relates to the technology of concentration and extraction of traditional Chinese medicine, and specifically to a device for concentration and extraction of traditional Chinese medicine. Background Technology

[0002] Concentration and extraction of Chinese herbal medicines is an important operation in the pretreatment of raw materials for the formation of Chinese medicine preparations. The concentration and extraction process of Chinese herbal medicines is generally divided into liquid acquisition and compression evaporation. In order to fully obtain the effective components in Chinese herbal medicines, the herbs need to be dried and crushed. Then, the crushed powdered herbs are placed in an extraction tank and a solvent is added to extract the active ingredients. Then, compression evaporation is carried out, that is, the extracted liquid is introduced into a concentration tank for concentration treatment.

[0003] For example, patent application publication number CN112717463A, publication date April 30, 2021, entitled "A Concentration and Extraction Device for Effective Components of Traditional Chinese Medicine," includes a housing, a water tank at the upper end of the housing, a water inlet at the upper end of the water tank with a valve fitted on the inlet, a partition inside the water tank with a water outlet at the lower end of the partition with a valve fitted on the outlet, a vertically mounted stirring shaft in the housing, the upper end of the stirring shaft passing through the upper end of the housing and the lower end of the water tank, a limiting block installed at the upper end of the stirring shaft and located inside the water tank, several stirring rods installed on the outer surface of the stirring shaft, a groove opened at the upper end of the stirring shaft, slots symmetrically opened at the lower part of the outer surface of the stirring shaft, a bevel gear fitted on the outer surface of the stirring shaft and located above the housing, and a motor installed at the upper end of the housing. This invention uses brush plate one, brush plate two, and brush plate three to clean the inner wall of the box, which is convenient, quick, saves manpower, reduces the labor intensity of workers, and improves work efficiency. At the same time, the hollow ring block sprays water on the inner wall of the box, which facilitates cleaning.

[0004] For example, the patent with authorization announcement number CN214680047U, authorization announcement date November 12, 2021, entitled "A Concentrated Extract of Traditional Chinese Medicine", includes a concentration tank, a heating tube, a stirrer, and a concentration tank cover. The concentration tank is placed on a platform scale. A glass tube level gauge is installed on the side of the concentration tank, a discharge valve is installed at the bottom of the concentration tank, a thermometer is installed on the inner side of the bottom of the concentration tank, and a pressure relief valve is installed on the concentration tank cover. This utility model, by setting up a glass tube level gauge and a platform scale, can monitor the volume and mass of the medicinal liquid in the concentration tank in real time, and then calculate the density of the medicinal liquid, which helps to control the degree of concentration and obtain a concentrated liquid with stable quality.

[0005] In existing technologies, the crushed powdered medicinal materials need to be placed in an extraction tank and a solvent is added to extract the active ingredients. After the medicinal materials are soaked in the extraction tank for a period of time, they are taken out. Since it is necessary to ensure that the medicinal materials can be taken out, they cannot be completely crushed. This results in some of the solvent encapsulating the active ingredients and being taken out along with the medicinal materials. Moreover, there are also a lot of residual active ingredients in the extracted medicinal materials, which will affect the subsequent compression evaporation and prevent the full extraction of the active ingredients from the medicinal materials. Summary of the Invention

[0006] The purpose of this invention is to provide a device for concentrating and extracting traditional Chinese medicine, so as to overcome the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A device for concentrating and extracting traditional Chinese medicine includes a tank body. A material receiving platform is movably arranged inside the tank body. The material receiving platform has multiple liquid outlet holes. A power rod is connected to the middle of the material receiving platform. A first driving member is connected to the upper end of the power rod. The first driving member drives the power rod to move vertically. A connecting rod is also fixed on the outer wall of the tank body. A matching extrusion plate is installed on the connecting rod. The power rod slides through the matching extrusion plate.

[0009] When the feeding platform moves to the same horizontal height as the matching extrusion plate and continues to move closer to each other, the matching extrusion plate extrudes the Chinese herbal medicines on the feeding platform.

[0010] In the aforementioned herbal medicine concentration and extraction device, a first pipe is provided on the upper side of the outer wall of the tank, and a second pipe is provided on the lower side of the outer wall of the tank. An electric valve is installed on the second pipe to control the outflow of liquid from the tank.

[0011] The above-mentioned herbal medicine concentration and extraction device has a concentration detector installed on the bottom wall of the feeding platform, which is used to detect the content of effective ingredients in the liquid on the feeding platform.

[0012] The aforementioned herbal medicine concentration and extraction device also includes a stirring mechanism on the power rod, which is used to stir the herbal medicine in the tank.

[0013] The above-mentioned herbal medicine concentration and extraction device includes a stirring mechanism comprising multiple circumferentially arranged receiving slots on a power rod. A stirring rod is rotatably mounted in each receiving slot via a pin. A torsion spring is sleeved on the pin. One end of the torsion spring is connected to the stirring rod, and the other end of the torsion spring is connected to the side wall of the receiving slot. When the power rod moves upward and the stirring rod contacts the matching extrusion plate, the matching extrusion plate presses the stirring rod so that it is completely contained within the receiving slot.

[0014] The above-mentioned herbal medicine concentration and extraction device further includes a power transmission unit in the stirring mechanism. The power transmission unit includes a first connecting shaft fixed at the bottom of the material receiving platform. The first connecting shaft slides through the bottom wall of the tank. A second connecting shaft is also slidably connected to the first connecting shaft. A power groove is also provided in the second connecting shaft. A power block is fixed on the first connecting shaft. The power block is slidably installed in the power groove. The bottom of the second connecting shaft is also connected to a second driving component. When the second driving component drives the second connecting shaft to rotate, the first connecting shaft rotates synchronously.

[0015] The above-mentioned herbal medicine concentration and extraction device further includes a stirring mechanism that includes a rotating drum rotatably connected to a power rod, and the rotating drum is connected to a first driving component.

[0016] In the aforementioned herbal medicine concentration and extraction device, a sealing ring is installed on the bottom wall of the tank, and the sealing ring is sleeved on the first connecting shaft.

[0017] The aforementioned herbal medicine concentration and extraction device has a heating rod embedded in the inner wall of the tank.

[0018] The aforementioned herbal medicine concentration and extraction device also includes a PLC controller, and the first drive unit, concentration detector, second drive unit, and heating rod are all electrically connected to the PLC controller.

[0019] In the above technical solution, the herbal medicine concentration and extraction device provided by the present invention drives the power rod to move vertically through the first drive unit, and causes the material taking platform to lift and take out the herbal medicine soaked in the tank. When the material taking platform and the herbal medicine move upward together, the matching extrusion plate is in a stationary state. Therefore, the material taking platform gradually moves closer to the matching extrusion plate. The movement between the matching extrusion plate and the material taking platform extrudes the herbal medicine, so that the residual solvent and effective ingredients in the herbal medicine are fully squeezed out and flow back into the tank from the liquid outlet, thus fully extracting the effective ingredients in the herbal medicine.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-11 As shown in the figure, this embodiment of the invention provides a traditional Chinese medicine concentration and extraction device, including a tank body 1. A material receiving platform 2 is movably arranged inside the tank body 1. The material receiving platform 2 has multiple liquid outlet holes 28. A power rod 3 is connected to the middle of the material receiving platform 2. A first driving member is connected to the upper end of the power rod 3. The first driving member drives the power rod 3 to move vertically. A connecting rod 4 is also fixed on the outer wall of the tank body 1. A matching extrusion plate 5 is installed on the connecting rod 4. The power rod 3 slides through the matching extrusion plate 5. When the material receiving platform 2 moves to the same horizontal height as the matching extrusion plate 5 and continues to move closer to each other, the matching extrusion plate 5 extrudes the traditional Chinese medicine on the material receiving platform 2.

[0036] Specifically, in this embodiment, the tank 1 is a cylindrical structure with an opening at the top, used to hold the crushed Chinese herbal medicine and solvent, providing a mixing area for the Chinese herbal medicine and solvent. The picking platform 2 is a cylindrical structure with an opening at the top, its diameter being slightly smaller than the diameter of the tank 1, allowing it to move freely axially within the tank 1. In the initial state, i.e., when no Chinese herbal medicine is placed in, the picking platform 2 is located at the bottom of the tank 1, preventing the Chinese herbal medicine from moving into the gap between the bottom wall of the picking platform 2 and the tank 1. The first driving component is a power element capable of driving the power rod 3 to move vertically, preferably an electric push rod (not shown in the figure). The mating extrusion plate 5 is a circular plate located directly above the tank 1, and the mating extrusion plate 5 is correspondingly mated with the picking platform 2, its diameter being equal to the inner diameter of the picking platform 2. Thus, when the picking platform 2 moves upward and contacts the mating extrusion plate 5, the mating extrusion plate 5 can press into the circular opening of the picking platform 2. Inside the cylindrical structure, the Chinese herbal medicines are squeezed. The process of concentrating and extracting Chinese herbal medicines generally consists of liquid extraction and compression evaporation. This embodiment mainly focuses on the improvement of liquid extraction. During operation, the crushed Chinese herbal medicines and solvent are placed into the tank 1 and soaked in the tank 1 for a period of time. After a period of time, most of the effective components in the Chinese herbal medicines dissolve in the solvent. The first driving component drives the material picking platform 2 to move upward. The liquid outlet 28 on the material picking platform 2 filters the Chinese herbal medicines, causing the material picking platform 2 to move upward. When the material picking platform 2 leaves the tank 1, it continues to move closer to the matching extrusion plate 5. The distance between the matching extrusion plate 5 and the bottom wall of the material picking platform 2 continuously decreases, thereby squeezing the Chinese herbal medicines on the material picking platform 2. The squeezed solvent carries the effective components back into the tank 1, thus fully extracting the effective components in the Chinese herbal medicines and making full use of the Chinese herbal medicine resources.

[0037] In another embodiment of the present invention, a first pipe 11 is provided on the upper side of the outer wall of the tank 1. The first pipe 11 is used to introduce a solvent for soaking Chinese herbal medicines. A second pipe 12 is provided on the lower side of the outer wall of the tank 1. An electric valve is installed on the second pipe 12 to control the outflow of the solvent in the tank 1. After the Chinese herbal medicines on the feeding platform 2 have been squeezed, the feeding platform 2 is driven to reset by the first driving component. Then, the second pipe 12 is opened by the electric valve, so that the solvent and active ingredients in the tank 1 flow out together.

[0038] In another embodiment of the present invention, a concentration detector 29 is provided on the bottom wall of the feeding platform 2, which is used to detect the content of effective components in the liquid on the feeding platform 2. The concentration detector 29 is prior art and will not be described in detail here.

[0039] In another embodiment of the present invention, a stirring mechanism 31 is further provided on the power rod 3, which is used to stir the Chinese herbal medicines in the tank 1; the stirring mechanism 31 includes a plurality of receiving slots 311 circumferentially formed on the power rod 3, and a stirring rod 312 is rotatably mounted in the receiving slot 311 by means of a pin. The width of the stirring rod 312 is smaller than the width of the receiving slot 311, so that the stirring rod 312 can be completely contained in the receiving slot 311, thereby allowing the power rod 3 to pass smoothly through the fitting extrusion plate 5, and the pin is sleeved on A torsion spring is provided, with one end connected to the stirring rod 312 and the other end connected to the side wall of the receiving groove 311. The torsion spring maintains the angle between the stirring rod 312 and the power rod 3, allowing the stirring rod 312 to extend out of the receiving groove 311. This ensures that the stirring rod 312 can contact the herbal medicine and solvent for mixing during movement. When the power rod 3 moves upward and contacts the matching extrusion plate 5, the matching extrusion plate 5 presses the stirring rod 312, completely retracting it into the receiving groove 311. When the power rod 3 rotates, the stirring rod 312 rotates accordingly, contacting and mixing the herbal medicine and solvent, allowing the effective components in the herbal medicine to mix into the solvent more quickly. As the power rod 3 rises and gradually passes through the matching extrusion plate 5, the matching extrusion plate 5 presses the stirring rod 312, completely retracting it into the receiving groove 311, allowing the power rod 3 to smoothly pass through the matching extrusion plate 5 and lift the material handling platform 2.

[0040] In another embodiment of the present invention, the stirring mechanism 31 further includes a power transmission unit. The power transmission unit includes a first connecting shaft 313 fixedly disposed at the bottom of the material receiving platform 2. The first connecting shaft 313 dynamically and sealably penetrates the bottom wall of the tank 1. A second connecting shaft 314 is slidably connected to the first connecting shaft 313. A power groove 315 is formed inside the second connecting shaft 314. The power groove 315 is square and parallel to the axis of the second connecting shaft 314. A power block 316 is fixed on the first connecting shaft 313 and is slidably installed inside the power groove 315. The power block 316 and power groove 315 are provided to ensure that the first connecting shaft 313 and the second connecting shaft 314 can only slide relative to each other in the vertical direction and cannot rotate relative to each other, thereby transmitting power. The bottom of the second connecting shaft 314 is also connected to the second driving member. The second driving member is in a fixed state and is connected to the second connecting shaft 314. When the second driving member drives the second connecting shaft 314 to rotate, the first connecting shaft 313 rotates synchronously. The second driving member is a power element that can drive the second connecting shaft 314 to rotate (not shown in the figure), preferably a servo motor. When the power rod 3 moves vertically, the picking platform 2 moves vertically accordingly, causing relative sliding between the first connecting shaft 313 and the second connecting shaft 314. At this time, the power block 316 also slides within the power groove 315. When the second driving member drives the second connecting shaft 314 to rotate, since the power block 316 can only slide vertically within the power groove 315, the second connecting shaft 314 drives the power block 316 to rotate synchronously, thereby causing the first connecting shaft 313 to rotate as well. The rotation of the first connecting shaft 313 drives the picking platform 2 to rotate, which in turn drives the power rod 3 to rotate, thereby driving the stirring rod 312 to rotate. Thus, while ensuring that the picking platform 2 can move vertically, the rotational power can also be transmitted to the picking platform 2, meaning that the picking platform 2 can move vertically and also rotate.

[0041] If the herbs are squeezed by the vertical relative movement between the feeding platform 2 and the matching extrusion plate 5, gaps or uneven force may easily form between the herbs, resulting in a low extraction rate of the active ingredients. The conventional solution is to have the feeding platform 2 return to the tank 1 multiple times and then squeeze the herbs on the feeding platform 2 multiple times. However, this method reduces the efficiency of obtaining the medicinal liquid. Therefore, when the feeding platform 2 and the matching extrusion plate 5 move relative to each other and squeeze the herbs, the feeding platform 2 can be driven to rotate slowly at a low speed by the power transmission unit. This reduces the gaps between the herbs, makes the force on the herbs more even, and effectively improves the efficiency of obtaining the medicinal liquid.

[0042] In another embodiment of the present invention, the stirring mechanism 31 further includes a rotating drum 317 rotatably connected to the power rod 3. The rotating drum 317 is fixedly connected to the first driving member. A working cavity is provided inside the rotating drum 317. A ball bearing 318 is rolled on the power rod 3. The ball bearing 318 is pressed against the bottom wall of the working cavity. The ball bearing 318 reduces the friction when the power rod 3 rotates. Thus, when the first driving member drives the rotating drum 317 to move up and down, the power rod 3 can rotate inside the rotating drum 317.

[0043] In another embodiment of the present invention, a sealing ring 13 is installed on the bottom wall of the tank 1. The sealing ring 13 is sleeved on the first connecting shaft 313. The sealing ring 13 is used to prevent the solvent in the tank 1 from flowing out from the connection between the tank 1 and the first connecting shaft 313 to achieve dynamic sealing.

[0044] In another embodiment of the present invention, a heating rod 14 is embedded in the inner wall of the can 1. The heating rod 14 is used to heat the solvent in the can 1, so that the effective ingredients in the Chinese herbal medicine can enter the solvent in time. The heating rod 14 is prior art and will not be described in detail here.

[0045] In another embodiment of the present invention, a PLC controller 6 is also included. The PLC controller 6 is installed on the outer wall of the tank 1. The first drive unit, the concentration detector 29, the second drive unit, and the heating rod 14 are all electrically connected to the PLC controller 6. The PLC controller 6 has a preset minimum effective ingredient concentration value K. The concentration detector 29 detects the real-time effective ingredient concentration value P. Every fixed time period T, the K value and the P value are compared. When P is less than K, the PLC controller 6 controls the first drive unit to drive the power rod 3 to move downward, thereby driving the material handling platform 2 back to the bottom of the tank 1.

[0046] Furthermore, it is obvious that the cylindrical structure of the material-retrieving platform 2 is designed to completely remove the Chinese herbal medicines. Since the material-retrieving platform 2 also needs to drive the power rod 3 to rotate vertically to stir the Chinese herbal medicines, it is difficult to remove the squeezed Chinese herbal medicines by tilting or flipping. Therefore, this invention provides a further embodiment in which the material-retrieving platform 2 includes an annular component 21 and a base plate 22. The first driving component is connected to the middle of the base plate 22. The base plate 22 is a circular plate structure. The annular component 21 is movably connected to the base plate 22. A groove 23 is formed inside the plate of the annular component 21, and the bottom of the groove 23 penetrates the annular component 21. A slider 24 is fixed on the side wall of the base plate 22. The slider 24 is slidably disposed within the slide groove 23. A first slide rod 25 is fixed to the top wall of the slide groove 23. A second slide rod 26 is slidably connected within the first slide rod 25. The bottom of the second slide rod 26 is fixed to the slider 24. A mounting spring 261 connects the first slide rod 25 and the second slide rod 26. The mounting spring 261 maintains the initial state of the first slide rod 25 and the second slide rod 26, thereby ensuring a stable state between the annular part 21 and the base plate 22 in the initial state, facilitating the removal of Chinese herbal medicine during lifting. In this way, the annular part 21 and the base plate 22 can maintain a stable state when removing and squeezing Chinese herbal medicine, and the annular part 21 and the base plate 22 can also be separated under external force, facilitating the removal of the squeezed Chinese herbal medicine.

[0047] Furthermore, the annular component 21 is also provided with a separation unit 27, which allows the annular component 21 and the base plate 22 to separate at a specific position. The separation unit 27 includes multiple arc-shaped grooves 271, preferably two, formed on the top edge of the annular component 21. An arc-shaped limiting plate 272 is slidably installed in the arc-shaped groove 271, and the arc-shaped limiting plate 272 can be completely housed within the arc-shaped groove 271. A limiting spring 273 is connected between the arc-shaped limiting plate 272 and the arc-shaped groove 271 to maintain the relative position of the arc-shaped limiting plate 272 and the arc-shaped groove 271. A pull rope 274 is also connected to the arc-shaped limiting plate 272. The pull rope 274 is initially in a slack state and passes through the first sliding rod 25 and connects to the second sliding rod 26. A circular stop is fixed on the connecting rod 4. The circular blocking frame 275 has an open bottom and a circular through hole in the middle. The diameter of the circular through hole is larger than the diameter of the annular component 21. The axis of the circular blocking frame 275 coincides with the axis of the annular component 21. Thus, when the material handling platform 2 moves upward, it can smoothly pass through the circular through hole into the circular blocking frame 275. A mounting rod is fixed on the inner wall of the circular blocking frame 275. A cylinder is rotatably mounted on the end of the mounting rod near the circular through hole via a rotating shaft 276. The rotating shaft 276 is also equipped with a ratchet and pawl mechanism (not shown in the figure). The ratchet and pawl mechanism is existing technology and will not be described in detail. The ratchet and pawl mechanism is used to make the rotating shaft 276 rotate counterclockwise in only one direction. Multiple stops 277 are evenly installed on the outer wall of the cylinder. The stops 277 can contact the arc-shaped limiting plates 272. The two arc-shaped limiting plates 272 superior The distance between the two ends that are close to each other should be less than the width of the stop 277, so that when the base plate 22 rotates and drives the arc-shaped limiting plate 272, the arc-shaped limiting plate 272 will not be stuck by the stop 277. liveDuring operation, when the material handling platform 2 moves upward, the arc-shaped limiting plate 272 contacts the stop block 277, thereby pushing the stop block 277 to rotate counterclockwise. The rotating shaft 276 also rotates counterclockwise. At this time, the stop block 277 cannot block the arc-shaped limiting plate 272. After the herbal medicines in the material handling platform 2 have been squeezed, the material handling platform 2 moves downward, that is, the first driving component pushes the base plate 22 downward. At this time, the arc-shaped limiting plate 272 contacts the stop block 277 again. Since the stop block 277 only... The ring can move counterclockwise, so the arc-shaped limiting plate 272 is blocked by the stop block 277 and cannot move downwards. That is, the ring part 21 is limited and cannot move downwards. At this time, the first driving member continues to push the base plate 22 downwards, thereby separating the ring part 21 from the base plate 22. At this time, the slider 24 slides in the slide groove 23, thereby causing the first slide rod 25 and the second slide rod 26 to separate and stretch the installation spring 261 and the pull rope 274. When the ring part 21 separates from the base plate 22 to a suitable distance... Then, the PLC controller 6 controls the first drive component to stop pushing the base plate 22. At this time, the pull rope 274 is exactly taut. When the annular component 21 separates from the base plate 22 to a suitable distance, it is easy to remove the Chinese herbal medicine. At this time, the power transmission unit can drive the base plate 22 to rotate rapidly. Under the action of centrifugal force, the Chinese herbal medicine on the base plate 22 is quickly thrown out. The thrown Chinese herbal medicine moves downward under the obstruction of the arc-shaped limiting plate 272, thereby completing the rapid removal of the Chinese herbal medicine. At this time, the arc-shaped limiting plate 272... The arc-shaped limiting plate 272 moves closely against the stop block 277. When the first driving member continues to push the base plate 22 downward, since the pull rope 274 has been stretched into a taut state, when the base plate 22 continues to move downward, driving the slider 24 and the second slide rod 26 to move, the pull rope 274 drives the arc-shaped limiting plate 272 to retract into the arc-shaped groove 271, thereby causing the stop block 277 to lose its limiting effect on the arc-shaped limiting plate 272, so that the ring member 21 and the base plate 22 can be smoothly driven downward, so that the material picking platform 2 can be reset.

[0048] Preferably, a hollow frustum 15 is fixedly provided at the upper end of the tank body 1. The diameter of the upper end face of the hollow frustum 15 is smaller than that of the lower end face. The minimum diameter of the hollow part of the hollow frustum 15 is larger than the diameter of the annular part 21. The axis of the hollow frustum 15 coincides with that of the annular part 21. When the Chinese herbal medicine is thrown out, it falls along the inner side wall of the arc-shaped limiting plate 272 onto the outer side wall of the hollow frustum 15, thereby preventing the thrown-out Chinese herbal medicine from flowing back into the tank body 1. The hollow frustum 15 can also be further configured as a unified collection unit to collect the Chinese herbal medicine in a unified manner. This embodiment is easy for those skilled in the art to conceive of, and will not be elaborated on here.

[0049] In the above embodiments, the movement modes of the material handling platform 2 can be divided into low-speed mode, uniform speed mode, and high-speed mode. In low-speed mode, the Chinese herbal medicines are in a state of being squeezed. At this time, the power transmission unit drives the material handling platform 2 to rotate at a low speed, so that the material handling platform 2 and the matching extrusion plate 5 rotate relative to each other, thereby reducing the gaps between the Chinese herbal medicines and making the force between the Chinese herbal medicines uniform, which can effectively improve the efficiency of obtaining the medicine liquid. In uniform speed mode, the Chinese herbal medicines are in a soaking state in the tank 1. At this time, the power transmission unit drives the material handling platform 2 to rotate at a uniform speed, thereby making the stirring mechanism 31 stir the Chinese herbal medicines. In high-speed mode, the Chinese herbal medicines have been squeezed. At this time, the first driving member keeps the material handling platform 2 in a stationary state, and at this time, the annular member 21 and the bottom plate 22 are separated to a suitable distance. The second driving member drives the bottom plate 22 to rotate quickly, so that the Chinese herbal medicines on the bottom plate 22 can be quickly taken out. All three movement modes require the cooperation of the first driving member and the second driving member.

[0050] The above motion modes are all switched through PLC controller 6. Those skilled in the art can program PLC controller 6 accordingly based on the above ideas. This is common knowledge to those skilled in the art and can be implemented using existing technology. No further details will be provided here.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
