[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] Please refer to Figures 1 to 9 , the present invention provides the following technical solutions: A heat recovery device for a traditional Chinese medicine extraction device, including a recovery device body and an extraction tank 1. The recovery device body includes a driving mechanism 6, a heat conduction mechanism 7 and a heat recovery component. The heat recovery component includes an inner layer heat recovery component 8 and an outer layer heat recovery component 4. The outer layer heat recovery component 4 is sleeved on the surface of the extraction tank 1. A driving mechanism 6 is installed at the top of the extraction tank 1. A lifting plate 5 is sleeved at the top of the driving mechanism 6. A feeding port 2 is opened on the surface of the extraction tank 1. Lifting channels 14 are opened on both sides of the outer layer heat recovery component 4. A heat conduction mechanism 7 is inserted into the lifting channels 14. The bottom ends of both sides of the lifting plate 5 are welded with outer layer lifting rods 24. The bottom ends of the outer layer lifting rods 24 are welded with a first limit convex disc 25, and the outer layer lifting rods 24 pass through both ends of the heat conduction mechanism 7. An inner layer heat recovery component 8 is installed inside the extraction tank 1. The top end of the inner layer heat recovery component 8 is fixedly welded to the middle of the lifting plate 5. This heat recovery device is used to recover and utilize the waste heat generated after each extraction of traditional Chinese medicine raw materials by the traditional Chinese medicine extraction device.

[0021] When the present invention is in use, the recycling device is assembled and connected to the traditional Chinese medicine extraction equipment. The inner heat recovery component 8 is installed inside the extraction tank 1, and the outer heat recovery component 4 is installed outside the extraction tank 1. The inner and outer heat recovery components are driven to expand downward by the driving mechanism 6. After the driving mechanism 6 controls the motor 17 to rotate, with the cooperation of the lead screw 21 and the threaded sleeve 22, the lifting plate 5 is driven to move up and down. The lifting plate 5 simultaneously triggers the movement of the inner heat recovery component 8 inside the extraction tank 1 and the outer heat recovery component 4 outside. Put in the traditional Chinese medicine raw materials, and support the raw materials through the inner heat recovery component 8. Open the front feeding port 2, and by controlling the driving mechanism 6 to drive each heat exchange plate 28 to move downward in turn, the traditional Chinese medicine raw materials can be put into each heat exchange plate 28 from the feeding port 2. Inject cold water from each heat exchange water injection pipe, use water flow as the heat exchange medium for waste heat recovery, control the discharge speed of the internal heat exchange medium of each drainage pipe, and realize the temperature control of the recovered hot water. With the help of the inner and outer heat recovery components 4, the heat is recovered and processed from the inside and outside of the extraction equipment respectively. During the whole process, the temperature on the surface of the extraction tank 1 is recovered by the outer heat recovery component 4, while the heat in the inner cavity of the extraction tank 1 and the heating element part in the center is recovered and processed by the inner heat recovery component 8.

[0022] In this embodiment, a diversion pipeline 11 is arranged at the bottom end of the inner wall of the extraction tank 1. An electric heating column 10 is installed on the surface of the diversion pipeline 11. The inner heat recovery component 8 is sleeved on the surface of the electric heating column 10. The bottom end of the diversion pipeline 11 is connected to an inner heat exchange drainage pipeline 3. The driving mechanism 6 includes a motor 17, a gear and a lead screw 21. The motor 17 is screwed on the surface of the extraction tank 1. A driving gear 18 is key-connected to the output shaft of the motor 17. A toothed belt 19 is sleeved on the surface of the driving gear 18. The other end of the toothed belt 19 is provided with a driven gear 20. The lead screws 21 are inserted at the tops of the driving gear 18 and the driven gear 20 respectively. The bottom of the driven gear 20 is movably connected to the surface of the extraction tank 1 through a bearing. A threaded sleeve 22 is formed on the surface of the lifting plate 5. The lead screw 21 passes through the inside of the threaded sleeve 22. A fixing hole 23 is formed in the middle of the lifting plate 5. The driving gear 18 and the driven gear 20 are on the same horizontal plane. In the outer and inner heat recovery components, the large-range high-temperature areas are concentrated towards the cavity areas laid inside them, and the injected cold water is used to achieve the purpose of exchanging and absorbing the heat after conduction. At the same time, the high-temperature concentration point area of the electric heating column 10 in the center of the extraction tank 1 is also subjected to targeted heat exchange treatment, so that there is no dead angle in the waste heat recovery range.

[0023] Specifically, after starting the motor 17, the operation of the motor 17 drives the rotation of the driving gear 18 on the output shaft. The driving gear 18 drives the driven gear 20 to rotate through the toothed belt 19, thereby controlling the rotation of the two lead screws 21. Eventually, the lifting plate 5 at the top can perform a lifting motion. The lifting plate 5 is used to drive the inner heat recovery device inside the extraction tank 1 and the outer heat recovery device outside the extraction tank 1 to perform a lifting motion, realizing the expansion and contraction of multiple heat exchange plates 28 and the expansion and contraction of the heat exchange ring 35 on the outer layer.

[0024] In this embodiment, the inner heat recovery component 8 includes an inner lifting sleeve 26, a heat exchange plate 28, and a guide post 9. A second limit convex disk 27 is welded to the outer side of the bottom end of the inner lifting sleeve 26. The heat exchange plate 28 is sleeved on the surface of the inner lifting sleeve 26, and a notch 29 is formed on the surface of the heat exchange plate 28. The guide post 9 is fixed on the inner wall of the extraction tank 1 and passes through the surface of each heat exchange plate 28. A first spring 30 is also welded to the surface of the heat exchange plate 28, and adjacent heat exchange plates 28 are connected in combination through the first spring 30. The connection between the guide post 9 and the heat exchange plate 28 is in interference fit. The top end of the inner lifting sleeve 26 is connected to an inner heat exchange water injection pipe 31, and the inner wall of the inner lifting sleeve 26 is in contact with the surface of the electric heating column 10. Through the inner heat recovery component 8, during the extraction of traditional Chinese medicine, the heat generated in the area of the electric heating column 10 at the central fixed point can be evenly diffused towards the side, so it can also accelerate the heat conduction process during the extraction of traditional Chinese medicine. With the lifting control of the inner heat recovery component 8 by the driving mechanism 6, it can also provide support for the traditional Chinese medicine raw materials inside, making the extraction process more uniform.

[0025] Specifically, after controlling the lifting plate 5 to move downward through the above-mentioned driving mechanism 6, the inner heat recovery device part moves downward through the second limit convex disk 27 at the end. Therefore, it will pull the bottommost heat exchange plate 28 to move downward synchronously. At this time, each layer of the heat exchange plate 28 can be moved downward in sequence. The first spring 30 between adjacent heat exchange plates 28 gradually changes from the compressed state in the groove 39 to the stretched state until each heat exchange plate 28 is unfolded and moves to different areas in the inner cavity of the extraction tank 1, realizing the purpose of recovering the waste heat in the inner cavity of the extraction tank 1. At the same time, by sleeving the inner lifting sleeve 26 on the surface of the electric heating column 10, the waste heat on the electric heating column 10 can be specifically absorbed. At this time, cold water is injected from the inner heat exchange water injection pipe 31 at the top, and the heat can be transferred to the cold water through the multiple heat exchange plates 28 and the middle inner lifting sleeve 26, realizing the purpose of recovering and utilizing the waste heat inside the extraction tank 1.

[0026] In this embodiment, the outer heat recovery component 4 includes a heat preservation sleeve 12, a lifting channel 14 and a heat exchange tank 13. Both ends of the heat preservation sleeve 12 are provided with the lifting channel 14, and the inner side of the heat preservation sleeve 12 is provided with the heat exchange tank 13. The front end of the heat preservation sleeve 12 is provided with an opening, and the opening area of the heat preservation sleeve 12 is connected with an outer heat exchange water injection pipe 15. The bottom end of the surface of the heat preservation sleeve 12 is connected with an outer heat exchange drainage pipe 16. The heat conduction mechanism 7 includes a transmission plate 32, a heat exchange ring 35 and a diversion air bag 36. Sealing grooves 39 are formed on the surfaces of the transmission plate 32 and the heat exchange plate 28. A second spring 34 is connected to the surface of the transmission plate 32. The transmission plate 32 is integrally formed at both ends of the heat exchange ring 35, and the diversion air bags 36 are connected between adjacent heat exchange rings 35. The bottom of the lifting channel 14 is connected with a sealing air bag 38.

[0027] Specifically, when the outer heat recovery device is unfolded by the above-mentioned driving mechanism 6, the downward movement of the first limit convex disk 25 is utilized to control the downward movement of each transmission plate 32. The unfolding process of this structure is the same as that of the heat exchange plate 28 until each heat exchange ring 35 is partially unfolded to the same spacing, and the topmost diversion air bag 36 is always in a fixed position and always remains in communication with both ends of the outer heat exchange water injection pipe 15. At this time, cold water is injected into the topmost diversion air bag 36 through the outer heat exchange water injection pipe 15, and the cold water can flow downward along the inside of each layer of diversion air bag 36. During the flowing process, the waste heat on the surface of the extraction tank 1 can be absorbed from the surface of the heat exchange ring 35, achieving the purpose of heat recovery and utilization. And the bottommost sealing air bag 38 can ensure the sealing treatment of the bottom of the lifting channel 14 when the whole outer heat recovery device is lifted and contracted by the driving mechanism 6 during the extraction process, achieving the heat preservation effect.

[0028] This embodiment also provides a recovery method using the above heat recovery device, including the following steps: S1. Assemble and connect the recovery device with the traditional Chinese medicine extraction equipment, install the inner heat recovery component 8 inside the extraction tank 1, and install the outer heat recovery component 4 outside the extraction tank 1; S2. Unfold the inner and outer heat recovery components downward through the driving mechanism 6. After the driving mechanism 6 controls the motor 17 to rotate, with the cooperation of the lead screw 21 and the threaded sleeve 22, the lifting plate 5 is driven to move up and down. The lifting plate 5 simultaneously triggers the movement of the inner heat recovery component 8 inside the extraction tank 1 and the outer heat recovery component 4 outside; S3. Put in traditional Chinese medicine raw materials, support the raw materials through the inner heat recovery component 8, open the front feeding port 2, and control the driving mechanism 6 to drive each layer of heat exchange plates 28 to move downward in sequence, and the traditional Chinese medicine raw materials can be put into the secrecy of each layer of heat exchange plates 28 from the feeding port 2; S4. Inject water and heat to extract traditional Chinese medicine. After extraction, drain the liquid medicine. Put traditional Chinese medicine raw materials and clear water from the feeding port 2, and a special pipeline and valve structure for discharging liquid medicine are connected to the bottom of the extraction tank 1. The liquid medicine generated after extraction inside the extraction tank 1 is discharged from the special discharge pipeline at the bottom; S5. Inject cold water from each heat exchange water injection pipeline, use water flow as the heat exchange medium for waste heat recovery, and control the discharge speed of the internal heat exchange medium of each drainage pipeline to achieve temperature control of the recovered hot water; S6. With the help of the inner and outer heat recovery components 4, recover the heat from the inside and outside of the extraction equipment respectively. During the whole process, the temperature on the surface of the extraction tank 1 is recovered by the outer heat recovery component 4, while the heat of the internal cavity of the extraction tank 1 and the heating element part in the center is recovered by the inner heat recovery component 8.

[0029] By building heat recovery components on the outside and inside of the traditional Chinese medicine extraction tank 1 at the same time, the purpose of heat exchange and recovery can be achieved from the outer surface, inner wall and inner cavity area at the same time, greatly improving the efficiency of heat exchange and recovery, shortening the time required for heat recovery, and at the same time not interfering with the traditional Chinese medicine extraction task of the inner extraction tank 1, and further playing a heat preservation effect during the extraction process and reducing heat loss.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
