Description

Technical Field

[0001] This invention relates to the field of cuscuta extract technology, specifically to an ultrasonic-microwave synergistic extraction device for cuscuta extract. Background Technology

[0002] As a medicinal plant with significant insecticidal potential, the study of its insecticidal active ingredients has always been a key focus in the field of plant-derived pesticides. Among them, the successful isolation and identification of compounds with significant antifeedant activity from *Corydalis tangutica* is a breakthrough achievement. This breakthrough not only clarified the core material basis of the insecticidal effect of *Corydalis tangutica*, but also promoted the leap from basic research to practical application of plant-derived insecticidal ingredients. It is widely regarded as an important milestone in the history of research on the insecticidal chemical components of *Corydalis tangutica*, providing solid theoretical support and material basis for the subsequent development of efficient and green pesticides.

[0003] In the industrial and laboratory extraction of cuscuta extract, the operating status of the extraction equipment directly determines the extraction efficiency, product purity, and resource utilization rate. Therefore, strict requirements are placed on the operating conditions of the equipment. Existing cuscuta extract equipment must be maintained within a specific temperature range during operation. This is because the active ingredients of cuscuta extract are quite sensitive to temperature. Excessive temperature will lead to the decomposition and inactivation of the active ingredients, reducing the efficacy of the extracted product. Excessive temperature will slow down the extraction rate, prolong the extraction cycle, and reduce the dissolution rate of the active ingredients, increasing the extraction cost. Therefore, the equipment needs to be equipped with a precise temperature control system to monitor and adjust the extraction environment temperature in real time to ensure that it remains stable within a suitable range and to guarantee the smooth progress of the extraction work.

[0004] Furthermore, in order to maximize the utilization of the extract and improve the extraction rate of citronella extract, the extraction process requires the continuous flow of the extract through the stirring device of the equipment to ensure that the extract and the citronella raw material are fully contacted and mixed. However, the existing extraction equipment still has obvious shortcomings in actual operation. The most prominent problem is that sedimentation easily occurs at the bottom during the extraction process. These sediments mainly come from two aspects: first, insoluble impurities in the citronella raw material cannot be completely dissolved during stirring and gradually settle to the bottom of the equipment as the extraction time increases; second, some of the extracted active ingredients will precipitate and crystallize under specific temperature and concentration conditions, thus forming sediment. The accumulation of sediment not only affects the normal operation of the stirring device, but also leads to poor flow of the extract and reduces the contact efficiency between the raw material and the extract. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An ultrasonic-microwave synergistic extraction device for extracting succulent root extract includes an extraction cylinder, a liquid inlet, a material inlet, and a discharge outlet. The liquid inlet and material inlet are located at the top of the extraction cylinder, and the discharge outlet is located at the bottom of the extraction cylinder. The extraction cylinder is characterized by having a stirring assembly inside, comprising an annular cylinder and a collar. The outer wall of the annular cylinder is rotatably connected to the inside of the collar. Multiple equally spaced stirring plates are installed on the outer wall of the annular cylinder. The collar drives the annular cylinder to slide circumferentially inside the extraction cylinder, causing the stirring plates to uniformly stir the solution inside the extraction cylinder. Furthermore, the rotation of the annular cylinder inside the collar further mixes the solution with the stirring plates.

[0006] Preferably, the inner wall of the collar is fixed with an annular locking block, and the outer wall of the annular cylinder is provided with an annular groove that matches the annular locking block, and the annular locking block is engaged inside the annular groove.

[0007] Preferably, a first toothed ring is fixed to the outer wall of the top end of the annular cylinder, a second toothed ring is installed on the inner wall of the cylinder body, and the first toothed ring and the second toothed ring are meshed and connected. A rotating shaft is provided on one side of the annular cylinder, and a support arm is fixed between the outer wall of the bottom end of the rotating shaft and the outer wall of the top end of the annular cylinder. A driving source is installed on the top of the cylinder cover, and the output end of the driving source is fixed to the top of the rotating shaft.

[0008] Preferably, the annular cylinder is provided with a mixing component, which includes an inner shaft disposed inside the annular cylinder and coaxially disposed with the annular cylinder. The top end of the inner shaft is fixed to the inner top wall of the annular cylinder. A lifting cylinder is sleeved on the outside of the inner shaft and slidably connected to the outer wall of the inner shaft. A bottom plate is fixed to the bottom of the lifting cylinder, and a mixing plate is fixed to the bottom of the bottom plate.

[0009] Preferably, a sliding block is provided on the outside of the lifting cylinder, and the sliding block is in the shape of a ring and is coaxially arranged with the lifting cylinder. A second through hole is opened in the middle of the sliding block, and the outer wall of the lifting cylinder is attached to the hole wall of the second through hole. A protrusion is fixed on the inner wall of the sliding block, and a linkage groove is opened on the lifting cylinder, and the protrusion is slidably connected inside the linkage groove.

[0010] Preferably, the linkage groove is composed of a spiral groove and a vertical groove, the spiral groove is located below the vertical groove, the top end of the spiral groove is connected to the bottom end of the vertical groove, and the initial position of the protrusion is located at the bottom end of the spiral groove.

[0011] Preferably, the top of the sliding block is fixed with two lifting shafts, and the annular cylinder is provided with a third through hole adapted to the lifting shafts. The lifting shafts are slidably connected inside the corresponding third through hole. One end of the two lifting shafts extending out of the annular cylinder is fixed with a connecting plate. The top of the connecting plate is fixed with a connecting shaft. The inner wall of the cylinder is fixed with an inner ring plate. The inner ring surface of the inner ring plate is provided with a slide rail, and the top end of the connecting shaft is slidably connected inside the slide rail.

[0012] Preferably, the outer wall of the annular cylinder is provided with a liquid suction port and a liquid discharge port, and the liquid discharge port is located above the liquid suction port.

[0013] Preferably, a baffle is fixed to the top of the sliding block.

[0014] Preferably, the extraction cylinder includes a cylinder body and a cylinder cover, both of which have cylinder cavities. The cylinder body's cylinder cavity faces upward, and the cylinder cover's cylinder cavity faces downward. The cylinder body and cylinder cover are connected by bolts.

[0015] The beneficial effects of this invention are as follows: 1. By using ultrasonic and microwave elements, an ultrasonic-microwave synergistic extraction mode is adopted. The two mechanisms complement each other and enhance each other's effects. The ultrasonic waves generated by the ultrasonic element can vibrate and impact the powder particles of bitter vine at high frequency, quickly breaking the plant cell walls and exposing the effective components of bitter vine extract within the cell walls, which facilitates full contact with the extraction solvent. The microwave element can rapidly heat the extraction solvent through microwave heating, while promoting the diffusion and mass transfer of solvent molecules and effective components, thus shortening the extraction cycle.

[0016] 2. The rotating shaft and support arm drive the annular cylinder to revolve circumferentially along the cylinder's axial direction. Simultaneously, the first toothed ring on the outer wall of the annular cylinder meshes with the second toothed ring on the inner wall of the cylinder. During the revolution, the annular cylinder itself rotates around the collar axis. This combination of revolution and rotation drives the stirring plate on the outer wall of the collar to perform omnidirectional, multi-track stirring motion inside the extraction cylinder. This not only covers the entire cross-section of the extraction cylinder but also ensures the mixing of the upper and lower layers of materials. This effectively avoids uneven mixing and concentration stratification of the bitter vine powder and the extraction solvent, ensuring that each portion of bitter vine powder can fully contact the extraction solvent. This improves the uniformity and stability of the extraction from the source, preventing the inhibition of dissolution of effective components due to excessively high local concentrations, and further guaranteeing extraction efficiency.

[0017] 3. When the connecting shaft slides from the bottom of the slide rail to the peak, the connecting plate drives the lifting shaft and sliding block to move upward synchronously. The protrusions on the inner wall of the sliding block slide along the linkage groove on the lifting cylinder. The linkage groove adopts a composite design of spiral groove and vertical groove. The protrusion first slides along the spiral groove, driving the lifting cylinder to rotate around the inner shaft, driving the mixing plate at the bottom to strongly stir the sedimented raw material at the bottom of the extraction cylinder, breaking the sediment layer. Then the protrusion enters the vertical groove and slides, driving the lifting cylinder to move upward synchronously, further disturbing the bottom material. At the same time, the gap between the sliding block and the bottom plate increases as the sliding block moves upward. The baffle blocks the drain port, and the extract enters the gap through the suction port. When the sliding block moves upward to the drain port and is no longer blocked by the baffle, the high-pressure liquid in the gap is sprayed onto the surface of the extract through the drain port, forming a forced circulation inside the equipment. This lifts the bottom liquid rich in raw materials to the upper layer, achieving full exchange of materials between the upper and lower layers, further strengthening the mass transfer process, ensuring that the bottom raw materials can also fully react, and greatly improving the thoroughness of extraction.

[0025] The following will refer to the attached reference. Figures 1 to 6 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] An ultrasonic-microwave synergistic extraction device for extracting styrax extract, such as... Figure 1-6 As shown, it includes: Extraction cylinder 10 includes a cylinder body 1011 and a cylinder cover 1012. Both the cylinder body 1011 and the cylinder cover 1012 have cylinder cavities. The cylinder cavity of the cylinder body 1011 faces upward, and the cylinder cavity of the cylinder cover 1012 faces downward. The cylinder body 1011 and the cylinder cover 1012 are connected by bolts.

[0027] The top of the cylinder cover 1012 is fixedly connected to the liquid injection port 11 and the material injection port 12. The extraction solvent used for extracting succulent can be injected into the inside of the cylinder body 1011 through the liquid injection port 11, while the powdered succulent powder can be injected into the inside of the cylinder body 1011 through the material injection port 12.

[0028] An observation window 13 is installed on the cylinder cover 1012, allowing staff to observe the extraction of trichotillomansis inside the extraction cylinder 10. A discharge port 14 is fixedly connected to the bottom of the cylinder body 1011, through which the extracted liquid can be discharged. An ultrasonic element 15 and a microwave element 16 are installed on the cylinder cover 1012 for extracting trichotillomansis.

[0029] The cylinder 1011 is equipped with a stirring assembly 20, which is used to stir and mix the bitter vine powder and extraction solvent inside the cylinder 1011.

[0030] The stirring assembly 20 includes an annular cylinder 21 disposed inside the cylinder body 1011. A collar 22 is disposed on the outside of the annular cylinder 21 and is coaxially disposed with the annular cylinder 21. The outer wall of the annular cylinder 21 is rotatably connected to the inner wall of the collar 22.

[0031] The inner wall of the collar 22 is fixed with an annular locking block 23, and the outer wall of the annular cylinder 21 is provided with an annular groove 24 that matches the annular locking block 23. The annular locking block 23 is engaged inside the annular groove 24. When the annular cylinder 21 rotates around its axial direction inside the collar 22, the annular locking block 23 slides inside the annular groove 24, thereby supporting the annular cylinder 21 and maintaining its stability.

[0032] A stirring plate 25 is fixed to the outer wall of the collar 22. When the collar 22 rotates around its axial direction, it can stir and mix the extraction solvent containing bitter vine powder.

[0033] A first toothed ring 26 is fixed to the outer wall of the top of the annular cylinder 21, and a second toothed ring 27 is installed on the inner wall of the cylinder body 1011. The first toothed ring 26 and the second toothed ring 27 are meshed and connected. When the annular cylinder 21 slides circumferentially around the axial direction of the cylinder body 1011, the first toothed ring 26 and the second toothed ring 27 can drive the annular cylinder 21 to slide inside the collar 22, thereby driving the stirring plate 25 to stir the extraction solvent containing bitter vine powder.

[0034] A rotating shaft 210 is provided on one side of the annular cylinder 21. A support arm 28 is fixed between the bottom outer wall of the rotating shaft 210 and the top outer wall of the annular cylinder 21. When the rotating shaft 210 rotates around its axis, the rotating shaft 210 drives the annular cylinder 21 to slide circumferentially around the axis of the cylinder body 1011 through the support arm 28, which enables the stirring plate 25 of the annular cylinder 21 to stir the extraction solvent in different areas inside the cylinder body 1011.

[0035] A drive source 211 is installed on the top of the cylinder cover 1012, and the output end of the drive source 211 is fixed to the top of the rotating shaft 210. The output end of the drive source 211 is used to drive the rotating shaft 210 to rotate, thereby driving the annular cylinder 21 to slide circumferentially inside the cylinder body 1011.

[0036] A mixing component 30 is provided on the annular cylinder 21 to accelerate the mixing efficiency of the extraction solvent and the bitter vine powder.

[0037] The mixing assembly 30 includes an inner shaft 31 disposed inside the annular cylinder 21, and the inner shaft 31 is coaxially disposed with the annular cylinder 21. The top end of the inner shaft 31 is fixed to the inner top wall of the annular cylinder 21. A lifting cylinder 32 is sleeved on the outside of the inner shaft 31, and the lifting cylinder 32 is slidably connected to the outer wall of the inner shaft 31. A bottom plate 33 is fixed to the bottom of the lifting cylinder 32, and a mixing plate 36 is fixed to the bottom of the bottom plate 33. When the lifting cylinder 32 slides up and down along the axial direction of the inner shaft 31, the lifting cylinder 32 can drive the bottom shaft 35 at the bottom of the bottom plate 33 to rotate, thereby mixing the extraction solvent and bitter vine powder located at the bottom of the extraction cylinder 10 by the mixing plate 36.

[0038] The lifting cylinder 32 is provided with a sliding block 37 on its outside. The sliding block 37 is ring-shaped and coaxially arranged with the lifting cylinder 32. A second through hole 38 is provided in the middle of the sliding block 37. The outer wall of the lifting cylinder 32 is attached to the hole wall of the second through hole 38. A protrusion 310 is fixed on the inner wall of the sliding block 37. A linkage groove 39 is provided on the lifting cylinder 32. The protrusion 310 is slidably connected inside the linkage groove 39.

[0039] It should be noted that the linkage groove 39 consists of a spiral groove and a vertical groove. The spiral groove is located below the vertical groove, and the top of the spiral groove is connected to the bottom of the vertical groove. The initial position of the protrusion 310 is located at the bottom of the spiral groove. When the sliding block 37 moves upward along the axial direction of the lifting cylinder 32, the protrusion 310 first slides from the bottom of the spiral groove to its top. At this time, the protrusion 310 drives the lifting cylinder 32 to rotate on the surface of the inner shaft 31, thereby driving the mixing plate 36 to mix the extraction solvent.

[0040] Two lifting shafts 311 are fixed to the top of the sliding block 37, and a third through hole 312 adapted to the lifting shafts 311 is provided on the annular cylinder 21. The lifting shafts 311 are slidably connected to the interior of the corresponding third through hole 312. A connecting plate 313 is fixed to one end of the two lifting shafts 311 extending out of the annular cylinder 21. A connecting shaft 316 is fixed to the top of the connecting plate 313. An inner ring plate 314 is fixed to the inner wall of the cylinder body 1011. A slide rail 315 is provided on the inner ring surface of the inner ring plate 314, and the top end of the connecting shaft 316 is slidably connected to the interior of the slide rail 315.

[0041] It should be noted that the slide rail 315 has peaks and valleys. When the connecting shaft 316 slides from the valley to the peak, the connecting shaft 316 drives the lifting shaft 311 to move upward inside the third through hole 312 through the connecting plate 313. The lifting shaft 311 synchronously moves the sliding block 37 upward inside the annular cylinder 21. The protrusion 310 of the sliding block 37 slides along the extension trajectory of the linkage groove 39, thereby driving the lifting cylinder 32 to rotate and move upward on the surface of the inner shaft 31.

[0042] The outer wall of the annular cylinder 21 is provided with a liquid suction port 317 and a liquid discharge port 318, and the liquid discharge port 318 is located above the liquid suction port 317. A baffle 319 is fixed on the top of the sliding block 37.

[0043] In use, the bitter vine powder and extraction solvent are injected into the cylinder 1011 through the feed port 12 and the liquid port 11, respectively. Since the ultrasonic element 15, microwave element 16 and drive source 211 are all electrically connected to the control system, turning on the electrical components through the control system is existing technology and will not be described in detail. The control system turns on the ultrasonic element 15, microwave element 16 and drive source 211. The ultrasonic element 15 uses ultrasound to vibrate and decompose the bitter vine powder and mix it with the extraction solvent.

[0044] The output of the drive source 211 drives the annular cylinder 21 on the collar 22 to slide circumferentially inside the extraction cylinder 10 via the rotating shaft 210. At this time, the first toothed ring 26 and the second toothed ring 27 drive the annular cylinder 21 to rotate inside the collar 22, while the annular locking block 23 slides inside the annular groove 24. The annular cylinder 21 drives the stirring plate 25 to stir the extraction solvent, thereby accelerating the extraction of trichotillosin.

[0045] As the annular cylinder 21 slides, the connecting shaft 316 slides along the extended trajectory of the slide rail 315. When the connecting shaft 316 slides from the valley bottom to the peak of the slide rail 315, it drives the lifting shaft 311 to move upward inside the third through hole 312 via the connecting plate 313. The lifting shaft 311 drives the sliding block 37 to slide on the surface of the lifting cylinder 32. When the protrusion 310 slides from the bottom end to the top end of the spiral groove, it will first drive the lifting cylinder 32 to rotate. At this time, the bottom shaft 35 drives the mixing plate 36 to stir the solution at the bottom end of the cylinder body 1011. At the same time, the gap between the sliding block 37 and the bottom plate 33 will increase, and the baffle 319 will continue to block the drain port 318. The external liquid enters between the sliding block 37 and the bottom plate 33 through the suction port 317. As the sliding block 37 moves upward, the amount of liquid between the sliding block 37 and the bottom plate 33 increases until the protrusion 310 slides from the spiral groove into the interior of the vertical groove and slides to the top of the vertical groove. At this time, the drain port 318 is removed from the blockage of the baffle 319, and the protrusion 310 will drive the lifting cylinder 32 to slide on the surface of the inner shaft 31. When the bottom plate 33 moves upward, the liquid between the sliding block 37 and the bottom plate 33 will be discharged to the liquid surface through the drain port 318, thereby preventing the extraction solvent from settling at the bottom of the cylinder body 1011. After the extraction of succulent is completed, the staff can open the valve on the discharge port 14 to discharge the succulent.
