[0014] A Chinese medicine extraction process, using the above-mentioned Chinese medicine extraction equipment, comprises the following steps: Step 1, preparing a medicinal solution: adding Chinese medicine, water and ethanol into the heating kettle, and then using the heating kettle to prepare a medicinal solution with the Chinese medicine, water and ethanol; Step 2, delivering the drug solution: after the heating kettle has prepared the drug solution, the drug solution is delivered to the annular filling cylinder through the delivery device and the infusion tube, so that the drug solution is added to the distillation kettle through the multiple liquid outlet pipes on the annular filling cylinder; Step 3, heating and distillation: the heating and distillation operation of the pharmaceutical solution is realized by the cooperation between the electric heating resistance wire and the electric heating column provided in the spiral sleeve. First, the pharmaceutical solution is heated to the boiling point of ethanol, so that the ethanol in the pharmaceutical solution evaporates first; Step 4, adjusting the temperature: when the pharmaceutical solution is heated for a long time, the temperature of the pharmaceutical solution will gradually exceed the boiling point of ethanol, the first driving motor is started to drive the winding drum to rotate, so that the winding drum unwinds the traction rope, and the sealing plate moves in the through-groove body. At the same time, the traction rope drives the slope-shaped ring sleeve to move longitudinally, so that the bottom of the metal rod enters the pharmaceutical solution, and the temperature of the pharmaceutical solution is adjusted; Step 5, condensation and transportation: start the exhaust fan to form a negative pressure area at the bottom of the exhaust fan, and transport the gas in the distillation kettle toward the direction of the bucket-shaped conveying frame, and the ethanol gas enters the gas circulation interlayer through the air inlet. After the ethanol gas enters the gas circulation interlayer, the ethanol gas will contact with the plurality of condensation fins. Through the temperature difference between the ethanol gas and the condensation fins, the moisture and ethanol in the ethanol gas will be condensed. After the ethanol gas contacts the side walls of the condensation fins and the internal through cavity, it will condense into liquid. The condensed liquid will flow into the slope-shaped collecting groove. The liquid will enter the annular groove body along the slope-shaped collecting groove, and finally be discharged from the annular groove body through the discharge pipe; Step 6, adjusting the liquid level: after evaporating the ethanol in the pharmaceutical solution for a period of time, the liquid level of the pharmaceutical solution in the distillation kettle will also decrease, and the winding drum is continuously driven to rotate by the first driving motor, so that the traction rope drives the sloped ring sleeve and the metal rod to continue to descend, thereby increasing the liquid level of the pharmaceutical solution in the distillation kettle; Step 7, evaporation and condensation: increasing the heating temperature of the electric heating resistance wire and the electric heating column, so that the water in the pharmaceutical solution also begins to evaporate, and through the recovery and condensation method of ethanol gas, the water is condensed and discharged from the distillation kettle; Step 8: Recycling: When the heating kettle continues to extract the Chinese medicine, the water and ethanol are mixed with the Chinese medicine for use.

[0015] The working principle and beneficial effects of the present invention are: 1. In the present invention, when extracting Chinese medicine, Chinese medicine, water and ethanol are mixed into a heating kettle, and then the Chinese medicine, water and ethanol are heated by the heating kettle to form a pharmaceutical solution, and then the pharmaceutical solution is transported to a distillation kettle, and a distillation heating component is used to heat and distill the pharmaceutical solution. During the heating process, because the boiling point of ethanol is lower than that of water, after the pharmaceutical solution is heated to a certain degree, the ethanol in the pharmaceutical solution will be volatilized first, and the ethanol gas is attracted by the exhaust fan, so that the ethanol enters the gas circulation interlayer in the bucket-shaped conveying frame after evaporation. After the ethanol gas contacts the condensation fins, due to the low temperature of the condensation fins, the ethanol will be condensed and enter the annular groove body, and then discharged through the discharge pipe The ethanol component in the pharmaceutical solution is discharged first, and then the heating temperature of the pharmaceutical solution by the distillation heating component is increased to evaporate the water in the pharmaceutical solution. After the water evaporates, it enters the gas circulation interlayer, and then the water is condensed under the action of the condensing fins and enters the annular groove body. The water is also discharged through the discharge pipe. When the discharged water and ethanol are extracted from the traditional Chinese medicine in the heating kettle, the condensed water and ethanol are continued to be heated and extracted with the new traditional Chinese medicine to realize the recycling of water and ethanol components. When the water and ethanol are recycled, the ethanol and water are classified and recycled, which is convenient for judging the recovery amount of water and ethanol, and also convenient for adjusting the amount of recycled water and ethanol and the amount of new traditional Chinese medicine added in the subsequent process.

[0016] 2. In the present invention, during the process of heating and rectifying the pharmaceutical solution by the rectification and heating component, as the pharmaceutical solution is heated, the ethanol in the pharmaceutical solution will evaporate first. Therefore, before most of the ethanol components in the pharmaceutical solution evaporate, the heating temperature of the pharmaceutical solution needs to be kept under control. During the gradual heating of the pharmaceutical solution, the temperature of the pharmaceutical solution will also rise, and the ethanol and water will gradually evaporate together. However, in this way, the ethanol and water cannot be classified and recovered. When the temperature of the pharmaceutical solution rises, the present invention selects to drive the sloped ring sleeve and multiple metal rods to descend, so that the bottom of the metal rod is in contact with the surface of the pharmaceutical solution, and the temperature of the pharmaceutical solution is reduced. After the ethanol in the pharmaceutical solution evaporates, the liquid level of the pharmaceutical solution will also decrease. At this time, the top area of ​​the rectification and heating component will not contact the pharmaceutical solution. At this time, the metal rod and the sloped ring sleeve are further lowered, so that more parts of the metal rod are immersed in the pharmaceutical solution, the liquid level of the pharmaceutical solution is increased, and the pharmaceutical solution continues to be in full contact with the rectification and heating component, so that the heating effect of the rectification and heating component is maximized.

The electric heating resistance wire 7 and the electric heating column 8 cooperate with each other to achieve the heating and distillation of the pharmaceutical solution.

[0022] A discharge assembly 200 is provided at the bottom of the distillation kettle 2, and the discharge assembly 200 includes a supporting platform 9, a discharge pipe 11 and a discharge hopper 12. The supporting platform 9 is fixedly connected to the bottom of the distillation kettle 2, and the electric heating column 8 is fixedly connected to the supporting platform 9. A sloped annular groove 10 is provided on the supporting platform 9, and a plurality of discharge pipes 11 are circumferentially connected on the sloped annular groove 10. A valve is provided at the bottom of the discharge pipe 11, and the bottom of the distillation kettle 2 is connected to the discharge hopper 12. After the pharmaceutical solution is heated and distilled, most of the water and ethanol components in the pharmaceutical solution have been evaporated, completing the concentration effect of the pharmaceutical solution, and then opening the plurality of valves to discharge the pharmaceutical solution through the plurality of discharge pipes 11. Because the bottom of the supporting platform 9 is the sloped annular groove 10, the pharmaceutical solution will flow in the direction of the discharge pipe 11 as much as possible during the discharge process through the discharge pipe 11, so that the pharmaceutical solution in the distillation kettle 2 has a good discharge effect.

[0023] The top of the distillation kettle 2 is provided with an evaporation condensation mechanism 300, which is connected to the feed end 3 of the heating kettle 1. The evaporation condensation mechanism 300 includes a bucket-shaped conveying frame 13, a condensation collection component and a heating ring plate 16. The bucket-shaped conveying frame 13 is fixedly connected to the top of the distillation kettle 2. A gas circulation interlayer 14 is provided in the bucket-shaped conveying frame 13. An exhaust fan 15 is provided on the top of the bucket-shaped conveying frame 13. A condensation collection component is provided in the gas circulation interlayer 14. The heating ring plate 16 is provided at the bottom of the gas circulation interlayer 14. A plurality of air inlets are provided on the circumference of the heating ring plate 16. As the pharmaceutical solution is heated, After the ethanol and water in the pharmaceutical solution are gradually evaporated, the exhaust fan 15 is started to form a negative pressure area at the bottom of the exhaust fan 15, and the gas in the rectification kettle 2 is transported in the direction of the bucket-shaped conveying frame 13, and the gas enters the gas circulation interlayer 14 through the air inlet. Because the gas contains easily condensable water or ethanol, in order to ensure that the gas will be condensed after entering the gas circulation interlayer 14, the heating ring plate 16 is powered to maintain a high temperature. The heating ring plate 16 is also a commonly used electric heating device in the prior art. The gas remains in a gaseous state during passing through the heating ring plate 16; The condensation collection assembly includes a sloped collection groove 17 and condensation fins 20. The sloped collection groove 17 is fixedly connected to the inner wall of the gas circulation interlayer 14. The bottom of the sloped collection groove 17 is connected to an annular groove body 18. The annular groove body 18 is connected to a discharge pipe 19. The discharge pipe 19 is connected to the feed end 3 of the heating kettle 1. A plurality of condensation fins 20 are fixedly connected to the inner circumference of the sloped collection groove 17. The condensation fins 20 are provided with through cavities. After the evaporated gas enters the gas circulation interlayer 14, the gas will contact with the plurality of condensation fins 20. Through the temperature difference between the gas and the condensation fins 20, the moisture and ethanol in the gas are condensed. The gas is in contact with the side walls and internal through cavities of the condensation fins 20. After contacting the cavity, it will condense into liquid, and the condensed liquid will flow into the sloped collecting groove 17, and the liquid will enter the annular groove body 18 along the sloped collecting groove 17, and finally be discharged from the annular groove body 18 through the discharge pipe 19, and the bottom end of the annular groove body 18 is set to be inclined, so that after the liquid enters the annular groove body 18, the liquid naturally flows in the direction of the discharge pipe 19, ensuring that the liquid in the annular groove body 18 is discharged as much as possible, and after the gas passes through the gas circulation interlayer 14 and enters the range of the exhaust fan 15, under the action of the centrifugal force generated during the rotation of the exhaust fan 15, the water and ethanol in the gas are thrown back to the sloped collecting groove 17 for discharge; The gas cylinder 34 is also included. The gas cylinder 34 is arranged in the gas circulation interlayer 14. The gas cylinder 34 is connected to a gas charging interface 35. The gas charging interface 35 extends to the outside of the distillation kettle 2. In order to ensure that the gas contacts and condenses with the condensation fins 20 during the circulation of the gas in the gas circulation interlayer 14, gas is injected into the gas cylinder 34 through the gas charging interface 35 to expand the gas cylinder 34 in the gas circulation interlayer 14. The outer wall of the gas cylinder 34 contacts with the multiple condensation fins 20 after expansion, thereby ensuring that the gas is supported when entering the gas circulation interlayer 14 and that the gas is in full contact with the multiple cooling fins, so as to facilitate full condensation of the gas.

[0024] Position adjustment components 500 are provided between the two sides of the solution adjustment component 400 and the distillation kettle 2. The solution adjustment component 400 is used to adjust the liquid level and temperature of the solution. The solution adjustment component 400 includes a sloped ring sleeve 21 and a metal rod 22. The sloped ring sleeve 21 moves longitudinally in the distillation kettle 2. The bottom circumference of the sloped ring sleeve 21 is fixedly connected with a plurality of metal rods 22. During the distillation heating component 100 heats and distills the pharmaceutical solution, as the pharmaceutical solution is heated, the ethanol in the pharmaceutical solution will evaporate first. Therefore, before most of the ethanol components in the pharmaceutical solution evaporate, the heating temperature of the pharmaceutical solution needs to be controlled. During the gradual heating of the pharmaceutical solution, the temperature of the pharmaceutical solution will also rise, and it will gradually evaporate together with ethanol and water. However, this does not allow the ethanol and water to be classified and recovered. When the temperature of the pharmaceutical solution rises, the present invention selects to drive the sloped ring sleeve 21 and the plurality of metal rods 22 to descend, so that the bottom of the metal rods 22 contacts the surface of the pharmaceutical solution, and the temperature of the pharmaceutical solution is reduced. After the ethanol in the pharmaceutical solution evaporates, the liquid level of the pharmaceutical solution will also decrease. At this time, the top area of ​​the distillation heating component 100 will not contact the pharmaceutical solution. At this time, the metal rods 22 and the sloped ring sleeve 21 are further lowered, so that more parts of the metal rods 22 are immersed in the pharmaceutical solution, and the liquid level of the pharmaceutical solution is increased, so that the pharmaceutical solution continues to contact the distillation heating component 100 in an all-round manner, so that the heating effect of the distillation heating component 100 is maximized. The slope design at the top of the sloped ring sleeve 21 is to ensure that the pharmaceutical solution will not be retained at the top of the sloped ring sleeve 21 after flowing through the surface of the sloped ring sleeve 21. The position adjustment assembly 500 includes a support frame 23 and a through slot 27. The support frame 23 is fixedly connected to one side of the distillation kettle 2. A rotating member 24 is fixedly connected to the support frame 23. A winding drum 25 is rotatably connected to the rotating member 24. A first driving motor 26 is arranged on the rotating member 24. The output end of the first driving motor 26 is fixedly connected to the winding drum 25. A through slot 27 is connected to the side wall of the distillation kettle 2. A sealing plate 28 is sealingly and slidably arranged in the through slot 27. A traction rope 29 is fixedly connected to the sealing plate 28. One end of the traction rope 29 is wound around the winding drum 25, and the other end of the traction rope 29 is fixedly connected to the sloped ring sleeve 21. When it is necessary to adjust the height of the sloped ring sleeve 21 and the metal rod 22, the first drive motor 26 is started to drive the winding drum 25 to rotate, so that the winding drum 25 unwinds or reels the traction rope 29. When the sealing plate 28 moves in the through-groove body 27, the traction rope 29 drives the sloped ring sleeve 21 to move longitudinally, and the sealing plate 28 can keep the through-groove body 27 sealed to prevent heat from escaping from the distillation kettle 2.

[0025] The heating kettle 1 also includes an annular filling cylinder 30 and a liquid infusion pipe 32. The annular filling cylinder 30 is fixedly connected to the distillation kettle 2. The annular filling cylinder 30 is located on the lower side of the bucket-shaped conveying frame 13. The bottom circumference of the annular filling cylinder 30 is connected with a liquid outlet pipe 31. A conveying device 33 is provided at the bottom of the heating kettle 1. The conveying device 33 and the annular filling cylinder 30 are connected with a liquid infusion pipe 32. After the heating kettle 1 prepares the pharmaceutical solution, the pharmaceutical solution is conveyed to the annular filling cylinder 30 through the conveying device 33 and the liquid infusion pipe 32, so that the medicinal solution is evenly filled into the distillation kettle 2 through multiple liquid outlet pipes 31.

[0026] Embodiment 2: Based on a Chinese medicine extraction device, this embodiment 2 also proposes a Chinese medicine extraction method, comprising the following steps: Step 1, preparing a medicinal solution: adding Chinese medicine, water and ethanol into a heating kettle 1, and then heating the Chinese medicine, water and ethanol into a medicinal solution through the heating kettle 1; Step 2: transporting the drug solution: after the heating kettle 1 prepares the drug solution, the drug solution is transported to the annular filling cylinder 30 through the transport device 33 and the infusion tube 32, so that the drug solution is poured into the distillation kettle 2 through the multiple liquid outlet pipes 31 on the annular filling cylinder 30; Step 3, heating distillation: The heating resistance wire 7 and the electric heating column 8 provided in the spiral sleeve 6 cooperate with each other to realize the heating distillation operation of the pharmaceutical solution. First, the pharmaceutical solution is heated to the boiling point of ethanol, so that the ethanol in the pharmaceutical solution evaporates first; Step 4, adjusting the temperature: when the pharmaceutical solution is heated for a long time, the temperature of the pharmaceutical solution will gradually exceed the boiling point of ethanol, and the first driving motor 26 is started to drive the winding drum 25 to rotate, so that the winding drum 25 unwinds the traction rope 29, and the sealing plate 28 moves in the through groove 27. At the same time, the traction rope 29 drives the slope ring sleeve 21 to move longitudinally, so that the bottom of the metal rod 22 enters the pharmaceutical solution, and the temperature of the pharmaceutical solution is adjusted; Step 5, condensation and transportation: start the exhaust fan 15, so that a negative pressure area is formed at the bottom of the exhaust fan 15, and the gas in the distillation kettle 2 is transported in the direction of the bucket-shaped conveying frame 13, and the ethanol gas enters the gas circulation interlayer 14 through the air inlet. After the ethanol gas enters the gas circulation interlayer 14, the ethanol gas will contact with a plurality of condensation fins 20. Through the temperature difference between the ethanol gas and the condensation fins 20, the moisture and ethanol in the ethanol gas are condensed. After the ethanol gas contacts the side walls and the internal through cavity of the condensation fins 20, it will condense into liquid. The condensed liquid will flow into the slope-shaped collecting groove 17, and the liquid will enter the annular groove body 18 along the slope-shaped collecting groove 17, and finally be discharged from the annular groove body 18 through the discharge pipe 19; Step 6, adjusting the liquid level: after a period of time, the ethanol in the pharmaceutical solution is evaporated, and the liquid level of the pharmaceutical solution in the distillation kettle 2 will also decrease. The first drive motor 26 continues to drive the winding drum 25 to rotate, so that the traction rope 29 drives the slope ring sleeve 21 and the metal rod 22 to continue to descend, thereby increasing the liquid level of the pharmaceutical solution in the distillation kettle 2; Step 7, evaporation and condensation: increasing the heating temperature of the electric heating resistance wire 7 and the electric heating column 8, so that the water in the pharmaceutical solution also begins to evaporate, and through the recovery and condensation method of ethanol gas, the water is condensed and discharged from the distillation kettle 2; Step 8: Recycling: When the heated kettle 1 continues to extract the Chinese medicine, the water and ethanol are mixed with the Chinese medicine for use.
