Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine soaking and extraction technology, specifically a high-efficiency extraction and soaking device for traditional Chinese medicine. Background Technology

[0002] In the extraction process of traditional Chinese medicinal materials, immersion extraction is a commonly used method. This involves soaking the medicinal materials in a solvent (such as water or ethanol) to allow the active ingredients to dissolve through diffusion and osmosis. However, existing immersion extraction equipment has the following significant drawbacks in practical applications:

[0003] 1. Low extraction efficiency: Traditional extraction equipment mainly relies on static soaking, which limits the contact area between the medicinal material and the solvent, resulting in high mass transfer resistance and slow release of active ingredients and long extraction time. This is especially true for hard medicinal materials with dense cell structures (such as roots, rhizomes, and seeds), whose cell walls are difficult to break down, further reducing the extraction efficiency.

[0004] 2. Difficulty in cleaning medicinal materials: After the existing equipment completes the extraction, the solvent is usually discharged through the discharge valve, but the medicinal materials remain in the soaking tank and need to be cleaned manually.

[0005] Therefore, we propose a high-efficiency extraction and leaching device for traditional Chinese medicinal materials. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a high-efficiency extraction and leaching device for traditional Chinese medicinal materials, which has the following beneficial effects:

[0017] 1. This is a high-efficiency extraction and leaching equipment for Chinese medicinal materials. An ultrasonic transducer is installed in the jacket of the soaking tank. The high-frequency vibration of ultrasonic waves generates a cavitation effect in the solvent, which destroys the cell walls of the medicinal materials and accelerates the release of active ingredients. The strong eddies and shear forces generated by the ultrasonic waves can enhance the permeability of the solvent and reduce the mass transfer resistance. It is especially suitable for hard medicinal materials such as roots, rhizomes and seeds, and significantly shortens the extraction time.

[0018] 2. This high-efficiency extraction and leaching equipment for Chinese medicinal materials uses a pressing mesh assembly to facilitate pressing of the medicinal materials, allowing them to be soaked in the leaching solution.

[0019] 3. This high-efficiency extraction and leaching equipment for Chinese medicinal materials uses a rotating component to easily rotate the soaking tank. After the liquid is discharged, a collection box is placed at the bottom of the soaking tank. The soaking tank is then rotated to empty the material, which is convenient for cleaning.

The rotating assembly 5 includes a transmission box 10, a motor 11, a worm gear 12, a worm wheel 13, and a rotating shaft 14. One end of the outer surface of the rotating shaft 14 is fixedly connected to the middle part of the outer surface of the right end of the soaking tank 3. A discharge valve 4 is installed on the lower part of the outer surface of the front end of the soaking tank 3. A pressing mesh assembly 6 is provided on the upper part of the soaking tank 3. The pressing mesh assembly 6 includes a hydraulic rod 7, a top plate 8, a connecting shaft 9, and a pressing mesh plate 17. The soaking tank 3 is composed of an inner shell and an outer shell. A sandwich layer is provided between the inner shell and the outer shell. An ultrasonic transducer 16 is installed inside the sandwich layer. The ultrasonic transducer 16 is fixed on the outer wall of the inner shell in the soaking tank 3.

[0029] There are two sets of pressing mesh plate 17 and connecting shaft 9. Two sets of hydraulic rods 7 are fixed to the middle of the upper outer surface of the first support 1 and the second support 2. The upper outer surface of the piston rod in each set of hydraulic rods 7 is fixedly connected to the left and right ends of the lower outer surface of the top plate 8. Two sets of connecting shafts 9 are fixed between the left and right sides of the upper outer surface of the pressing mesh plate 17 and the left and right sides of the lower outer surface of the top plate 8. The outer wall of the pressing mesh plate 17 is inserted into the soaking tank 3. A bearing is installed between the driven shaft 15 and the second support 2, and the driven shaft 15 is rotatably connected to the second support 2 through the bearing. Bearings are installed between the rotating shaft 14 and the soaking tank 3, the first support 1, and the transmission box 10, and the rotating shaft 14 is rotatably connected to the soaking tank 3, the first support 1, and the transmission box 10 through the bearing. The transmission box 10 is fixedly installed on the upper part of the outer surface of the right side of the first bracket 1. The worm 12 and the worm wheel 13 are both located inside the transmission box 10. The motor 11 is fixedly installed on the lower part of the outer surface of one side of the transmission box 10. The worm wheel 13 is located on the upper outer surface of the worm 12. The worm wheel 13 is fixedly installed on the outer wall of the end of the rotating shaft 14 away from the soaking tank 3. The upper outer surface of the worm 12 meshes with the worm wheel 13. The worm 12 is a single-start worm, and the lead angle of the worm 12 is less than the equivalent friction angle.

[0030] It should be noted that this utility model is a high-efficiency extraction and leaching device for traditional Chinese medicinal materials, as shown in the attached instruction manual. Figure 1As shown, the soaking solution is placed in the soaking tank 3, and then the medicinal materials to be soaked are placed inside the soaking tank 3. The operation of the hydraulic rod 7 drives the pressing screen 17 to descend, and the pressing screen 17 presses the medicinal materials inside the soaking tank 3 to ensure that the medicinal materials are completely soaked. The ultrasonic transducer 16 is connected to an ultrasonic generator and is fixed on the outer wall of the inner shell. The high-frequency ultrasonic vibration generates tiny bubbles in the solvent and collapses instantly, destroying the cell walls of the medicinal materials and allowing the effective components inside the cells to be quickly released into the solvent. This method is suitable for medicinal materials with hard and dense cell structures. (e.g., roots and seeds) Ultrasonic waves create strong eddies and shear forces in the solvent, enhancing solvent permeability, reducing mass transfer resistance during static soaking, and shortening extraction time. After extraction, the liquid is first discharged through discharge 4, and then the hydraulic rod 7 drives the pressing screen 17 to rise and reset. Afterward, a collection box is placed at the bottom of the soaking tank 3, and the operation of the motor 11 drives the worm gear 12 to rotate. The worm gear 12 drives the rotating shaft 14 to rotate through the worm wheel 13. The rotating shaft 14 drives the soaking tank 3 to tilt and pour out the medicinal materials, reducing the difficulty of cleaning.
