Description

Technical Field

[0001] This utility model relates to the technical field of traditional Chinese medicine extraction devices, specifically a high-efficiency extraction device for Niuhuang Jiedu tablets with a multi-stage separation structure. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) extraction, the extraction efficiency of active ingredients in compound preparations such as Niuhuang Jiedu tablets has always been a focus of industry attention. Traditional extraction devices often suffer from low dissolution rates of active ingredients due to insufficient crushing of medicinal materials and uneven stirring and heating. Furthermore, single-stage extraction suffers from insufficient solvent utilization and high residue levels. Meanwhile, manual operation is cumbersome and lacks automation, making it difficult to meet the needs of large-scale production. While multi-stage extraction devices can improve efficiency, their complex structural design and poor connection between crushing and extraction stages can easily lead to material deposition and uneven heat distribution, affecting the purity and yield of the extract. Therefore, there is an urgent need for an extraction device with efficient crushing, multi-stage separation, and automated control functions to address the pain points of low extraction efficiency, high energy consumption, and complex operation in traditional processes, and to promote the intelligent and refined development of TCM extraction technology.

[0003] As disclosed in CN214613294U, this invention provides a herbal cell-wall breaking processing device suitable for batch processing of traditional Chinese medicine (TCM). The device comprises a hot water immersion system, a pressure-relief tank, an air compressor for pressurizing the tank, a heating device for heating the tank, and a cyclone separator. The pressure-relief valve of the pressure-relief tank is connected to the inlet of the cyclone separator. After being immersed in hot water by the system, the TCM herbs are fed into the pressure-relief tank for heating and pressurization. Finally, the pressure in the tank is rapidly released, causing the herbs to be ejected into the cyclone separator for gas separation, resulting in a cell-wall broken solid-liquid mixture.

[0004] While the aforementioned methods can significantly improve the extraction efficiency of effective components from traditional Chinese medicine (TCM), thereby improving production processes and enhancing the utilization of TCM resources, the device lacks automatic material crushing mechanisms during operation, requiring an additional crusher, resulting in a cumbersome operation process. Furthermore, the device lacks mixing and stirring measures during the extraction process, hindering the guarantee of uniform heating of the extract. Therefore, we propose a high-efficiency extraction device for Niuhuang Jiedu tablets (a TCM formula) with a multi-stage separation structure. This solves the material crushing and uniform heating problems of the existing device, improving its ease of use and heating efficiency. Utility Model Content

The drive gear 15 and the driven gear 16 mesh with each other. The drive gear 15 and the driven gear 16 are rotatably installed on the outer wall of the crushing bin 2. A drive motor 17 is fixedly installed on the outer wall of the crushing bin 2. The output end of the drive motor 17 is fixedly connected to the shaft end of the drive gear 15 through a coupling.

[0026] In this embodiment, the settled medicinal liquid is pumped to the secondary extraction tank 11 by the liquid pump 9, and a fixed amount of water is added to the secondary extraction tank 11 through the water inlet. Then, the second heating coil 26 of the secondary extraction tank 11 is turned on to further heat the medicinal liquid for the set time.

This avoids the sedimentation of the medicine and improves the heating uniformity of the medicine. After the medicine in the primary extraction tank 1 is heated to the set time, the rotary motor 3 and the first heating coil 19 are turned off. After the medicine residue settles for a period of time, the liquid pump 9 is turned on by the PLC controller 31 to pump the settled medicine to the secondary extraction tank 11. A certain amount of water is added to the secondary extraction tank 11 through the water inlet. Then, the second heating coil 26 of the secondary extraction tank 11 is turned on to further heat the medicine to the set time, and it settles again. Finally, the medicine is discharged to the next process through the second drain port 30. The first drain port 22 and the first drain outlet 22 are opened to discharge the residue from the tank, and the next round of medicine extraction can be carried out.
