Description

Technical Field

[0001] This utility model relates to the field of countercurrent extraction technology, and in particular to a countercurrent extraction device for extracting Li medicine. Background Technology

[0002] Li medicinal herbs often contain multiple components, only a portion of which are effective medicinal ingredients. Li medicine extraction is the process of separating these effective components from the medicinal material. Countercurrent extraction is a commonly used method in Li medicine extraction. Countercurrent extraction utilizes the difference in solubility of a solute in two immiscible solvents to transfer the solute from one solvent to the other. Since the effective components of Li medicine have different solubilities in different solvents, countercurrent extraction can transfer the target components from the herbal extract to a specific solvent, achieving separation and enrichment.

[0003] However, existing countercurrent extraction devices inevitably leave solvent residues during use, which can easily affect subsequent production. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a countercurrent extraction device for extracting Li medicine, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a countercurrent extraction device for extracting Li medicinal herbs, comprising a countercurrent extraction tank containing an extractant and an extractant solution. The countercurrent extraction tank is internally equipped with a mixing rack. A rotating support is fixedly mounted on the top of the mixing rack for support. A scraper for cleaning the phase liquid is fixedly mounted inside the rotating support. A fixed magnet for attraction is fixedly mounted on the bottom of the scraper. An overflow outlet pipe for discharging the mixed phase liquid is fixedly mounted on the top of the countercurrent extraction tank. A separation tank for separating the phase liquid is fixedly mounted on one end of the overflow outlet pipe. A rotating cleaning rack for cleaning the inner wall of the separation tank is rotatably connected inside. A permanent magnet for attraction is fixedly mounted on the top of the rotating cleaning rack.

[0006] Preferably, in any of the above embodiments, a fixed support is fixedly installed at the bottom of the countercurrent extraction tank to support it, and one end of the stirring rack is fixedly installed at the top of the fixed support.

[0007] The above technical solution is adopted: the fixed support at the bottom of the countercurrent extraction tank provides stable support for the entire device, ensuring that the countercurrent extraction tank remains stable during operation and avoiding shaking or tipping. One end of the stirring rack is fixed to the top of the fixed support to ensure the stability of the stirring rack during operation, so that the stirring rack can properly mix the extract and the extract in the countercurrent extraction tank, laying the foundation for subsequent countercurrent extraction operations.

[0008] Preferably, in any of the above embodiments, the rotating support is rotatably connected to the inside of the countercurrent extraction tank, and the two ends of the rotating support are provided with grooves to support the scraping blades.

[0009] The above technical solution is adopted: the rotating bracket is rotatably connected inside the countercurrent extraction tank, and the grooves at both ends provide a stable support position for the scraper. When the stirring rack is working, the rotating bracket rotates synchronously with the stirring rack, driving the scraper to rotate inside the countercurrent extraction tank, so that the scraper can perform a comprehensive and stable scraping and cleaning of the inner wall of the countercurrent extraction tank, effectively reducing the residue of the phase liquid on the tank wall.

[0010] Preferably, in any of the above embodiments, the scraping blade includes a scraper for scraping, a detachable spring for providing power, and a fastening block for engaging. The scraper is engaged inside the rotating bracket, and the detachable spring is fixedly installed inside the scraper. One end of the detachable spring is fixedly installed with a fastening block that moves inside the scraper.

[0011] The above technical solution is adopted: the scraper blade is engaged inside the rotating bracket, and the inner wall of the countercurrent extraction tank is scraped and cleaned by the rotating bracket. The disassembly spring inside the scraper blade provides power to the fastening block. When it is necessary to install or remove the scraper blade, the scraper blade can be easily fixed on the rotating bracket or removed by operating the fastening block and using the elastic force of the disassembly spring, which facilitates the maintenance and replacement of the scraper blade.

[0012] Preferably, in any of the above embodiments, the fixed magnet is fixedly installed at the bottom of the scraper, and the fixed magnet is located inside the countercurrent extraction tank.

[0013] The above technical solution is adopted: the fixed magnet block is fixed at the bottom of the scraper and located inside the countercurrent extraction tank. Its main function is to generate magnetic attraction with the permanent magnet at the top of the rotating cleaning rack inside the separation tank. When the scraper rotates with the rotating support, the fixed magnet block drives the rotating cleaning rack to rotate through magnetic attraction, so that the rotating cleaning rack can clean the inner wall of the separation tank and realize the synchronous cleaning of the phase liquid residue inside the two tanks.

[0014] Preferably, in any of the above embodiments, a partition is provided between the separation tank and the countercurrent extraction tank to separate the two, and the separation tank is fixedly installed at the bottom of the countercurrent extraction tank.

[0015] The above technical solution is adopted: the partition between the separation tank and the countercurrent extraction tank effectively separates the two, avoiding mutual interference between the two liquids during the extraction process. At the same time, the partition does not affect the mutual adsorption between the magnets. The separation tank is fixed at the bottom of the countercurrent extraction tank and receives the mixed phase liquid discharged from the countercurrent extraction tank through the overflow outlet pipe for phase-liquid separation operation.

[0016] Preferably, in any of the above embodiments, the permanent magnet includes an electric telescopic rod for driving, a movable seat for fixing, and a magnetic block for magnetic attraction. The electric telescopic rod is fixedly installed inside the rotating cleaning frame. One end of the electric telescopic rod is fixedly installed with a movable seat that moves inside the rotating cleaning frame. The movable seat has a magnetic block fixedly installed inside. The electric telescopic rod is signal-connected to a main control unit for automated control.

[0017] The above technical solution is adopted: the electric telescopic rod of the permanent magnet is controlled by the main control unit and installed inside the rotating cleaning frame. When it is necessary to adjust the magnetic attraction between the permanent magnet and the fixed magnet block, the main control unit controls the electric telescopic rod to extend and retract, driving the movable seat to move inside the rotating cleaning frame, thereby adjusting the position of the magnet block. By changing the distance between the two, the magnetic attraction force can be adjusted, thereby controlling whether the rotating cleaning frame rotates with the scraper, which facilitates flexible control of the movement of the rotating cleaning frame.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. A rotating support is installed inside the countercurrent extraction tank, which rotates with the stirring. The rotating support drives the scraper to rotate, so that the scraper scrapes and cleans the inner wall of the countercurrent extraction tank. At the same time, the magnetic attraction between the fixed magnet block and the permanent magnet causes the scraper to drive the rotating cleaning rack to clean the inner wall of the separation tank. This reduces the residual phase liquid inside the countercurrent extraction tank and the separation tank, reduces the impact of the residual phase liquid on subsequent production, and improves the quality and stability of countercurrent extraction.

[0020] 2. The permanent magnet is set as a movable structure that can be extended and adjusted inside the rotating cleaning frame. The movement of the permanent magnet is controlled according to the rotation requirements. The distance between the permanent magnet and the fixed magnet block is adjusted, and the magnetic attraction force between the two is adjusted. This controls whether the rotating cleaning frame can rotate with the scraper, making it easy to adjust and control the movement of the rotating cleaning frame.

[0043] The working principle of the countercurrent extraction device for extracting Li medicine of this utility model is as follows:

[0044] The Li medicine extract and the extract solution are added to the countercurrent extraction tank 1. The stirring rack 2 is started, which drives the rotating support 3 to rotate. The scraper 4 on the rotating support 3 rotates accordingly. The scraper 41 scrapes and cleans the inner wall of the countercurrent extraction tank 1 to reduce the residual phase liquid. During the rotation of the fixed magnet block 5 at the bottom of the scraper 4, if the electric telescopic rod 91 of the permanent magnet 9 in the separation tank 7 extends, the magnetic block 93 will approach the fixed magnet block 5, and the two will be magnetically attracted. Under the action of magnetic attraction, the fixed magnet block 5 drives the permanent magnet 9, which in turn drives the rotating cleaning rack 8 to rotate, cleaning the inner wall of the separation tank 7. The mixed phase liquid flows into the separation tank 7 through the overflow outlet pipe 6 for separation. Throughout the process, the countercurrent extraction tank 1 and the separation tank 7 work together, and the scraper 4 and the rotating cleaning rack 8 cooperate to effectively reduce the residual phase liquid and improve the quality and stability of the countercurrent extraction of Li medicine.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] 1. A rotating support 3 is installed inside the countercurrent extraction tank 1, which rotates with the stirring. The rotating support 3 drives the scraper 4 to rotate, so that the scraper 4 scrapes and cleans the inner wall of the countercurrent extraction tank 1. At the same time, the magnetic attraction between the fixed magnet block 5 and the permanent magnet 9 causes the scraper 4 to drive the rotating cleaning frame 8 to clean the inner wall of the separation tank 7, thereby reducing the residual phase liquid inside the countercurrent extraction tank 1 and the separation tank 7, reducing the impact of the residual phase liquid on subsequent production, and improving the quality and stability of countercurrent extraction.

[0047] 2. The permanent magnet 9 is set as a movable structure that can be extended and adjusted inside the rotating cleaning frame 8. The permanent magnet 9 is controlled to move according to the rotation requirements. The distance between the permanent magnet 9 and the fixed magnet block 5 is adjusted to adjust the magnetic attraction force between the two. This can control whether the rotating cleaning frame 8 can rotate with the scraper 4, making it convenient to adjust and control the movement of the rotating cleaning frame 8.
