Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical engineering technology, and in particular to a crushing and extraction mechanism for separating components of traditional Chinese medicine. Background Technology

[0002] The separation of components from traditional Chinese medicine (TCM) refers to the process of extracting and separating medicinally valuable components from a complex system of TCM materials. There are various methods for TCM component separation, among which solvent extraction is a commonly used method. During solvent extraction, the physical state of the TCM materials has a crucial impact on the extraction efficiency and effectiveness.

[0003] Chinese medicinal herbs are crushed into suitable particle sizes by a crushing and extraction mechanism, which destroys the internal cell structure of the herbs and makes it easier to release the active ingredients. Then, in the extraction section, the crushed herbs are extracted using a suitable solvent, allowing the active ingredients to dissolve in the solvent. Afterward, the extract is separated from the solid residue by means of filtration, thus completing the initial separation process of the Chinese medicinal components.

[0004] In existing traditional Chinese medicine (TCM) crushing and extraction mechanisms, the screening device is mainly used to separate the solid residue and extract after extraction. However, in the crushing stage, there is usually no specially designed fine screening device for separating dust and slag. Even if there are some simple screens, their aperture size is only to control the size of the crushed TCM particles. They cannot effectively intercept and separate fine impurities such as dust and slag. Because dust and slag cannot be screened out, these impurities are easily mixed into the extract, making the extract turbid. Whether further purification processes such as evaporation concentration, vacuum distillation, or membrane separation are used, the impurities will interfere with the normal process, increase the difficulty of purification, consume more energy and materials, and drive up production costs. Therefore, a TCM component separation crushing and extraction mechanism is proposed to solve the above problems. Utility Model Content

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by adding a special fine screening process in the crushing stage, the Chinese medicinal materials are first screened by vibration to remove dust and slag, so as to avoid impurities from being mixed into the extract. The subsequent purification process can be carried out smoothly and efficiently, which greatly reduces the purification time, reduces the extra loss of energy and materials, and effectively ensures the purity of the extract, laying a solid foundation for the production of high-quality Chinese medicinal ingredients.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a crushing and extraction mechanism for separating Chinese herbal medicine components, including a base 1, an immersion tank 2 and a crushing box 3 are assembled on the top of the base 1, a discharge port 5 is assembled between the immersion tank 2 and the crushing box 3, a feed port 4 is provided on the top of the crushing box 3, a screening component 8 and a grinding component 15 are arranged inside the crushing box 3, a temperature control component 20 is arranged on the outside of the immersion tank 2, a liquid inlet pipe 6 is assembled on the top of the immersion tank 2, and a liquid outlet pipe 7 is assembled on the bottom of the immersion tank 2;

[0036] The screening assembly 8 includes a motor 9, which is mounted in the middle of the crushing box 3. An eccentric block 10 is fixedly connected to the output end of the motor 9. A rotating shaft 13 is provided inside the crushing box 3. A screen 11 is fixedly connected to the outside of the rotating shaft 13. A collection box 14 is provided directly below the screen 11. A spring rod 12 is mounted at the bottom of the screen 11. The rotating shaft 13 is rotatably connected inside the crushing box 3. The eccentric block 10 abuts against the bottom of the screen 11. The discharge port 5 is located on the side of the screen 11 near the immersion tank 2.

[0037] After starting motor 9, its output power drives eccentric block 10 to rotate rapidly. Due to its eccentric structure, eccentric block 10 continuously and forcefully impacts the bottom of screen 11. Simultaneously, spring rod 12 assists, coordinating with the impact of eccentric block 10 to generate high-frequency and intense vibrations in screen 11. Because the dust and powder particles are extremely small, under the intense vibration of screen 11, they easily pass through the screen and fall into the collection box 14 below, achieving initial separation from the main body of the medicinal materials. Larger particles of the medicinal materials, however, are... The screen 11 has a reasonable inclined design, which allows it to fall smoothly into the immersion tank 2 through the outlet 5 under the action of gravity, awaiting subsequent processing. This method effectively removes fine impurities such as dust and powder hidden in Chinese medicinal materials, preventing them from mixing into the extract from the source, thus preventing interference with the subsequent complex purification process, greatly reducing the pressure of subsequent purification, and can also accurately screen out the appropriate particle size for extraction according to actual needs, making the Chinese medicinal materials entering the extraction stage more standardized in particle size, and significantly improving the pre-treatment quality of Chinese medicinal materials.

[0038] Reference Figure 1 and Figure 5 The temperature control component 20 includes a heat exchange tank 21, which is located on one side of the base 1. A heat exchange pump 22 is installed in the middle of the heat exchange tank 21. A heat exchange ring 23 is fitted on the outer side of the immersion tank 2. A temperature detector 24 is fixedly connected to the side of the heat exchange ring 23 near the heat exchange tank 21. A PLC controller 25 is installed on the side of the heat exchange tank 21 away from the heat exchange ring 23. The heat exchange ring 23 is fixedly connected to the output end of the heat exchange pump 22. A return pipe 26 is installed between the immersion tank 2 and the heat exchange tank 21.

[0039] Temperature detector 24 accurately senses the temperature inside the immersion tank 2 in real time and quickly feeds the data back to PLC controller 25. PLC controller 25 adjusts heat exchange pump 22 in real time based on the feedback information to ensure that the immersion tank 2 always maintains a suitable extraction temperature, ensuring that different Chinese herbal medicine components can be fully dissolved under optimal temperature conditions. Suitable solvent is injected into the immersion tank 2 through inlet pipe 6. The solvent is fully mixed and contacted with the crushed Chinese herbal medicine, promoting the rapid dissolution of the effective components. After extraction, the extract flows out smoothly through outlet pipe 7. This design, which combines precise temperature control with efficient extraction, not only maximizes the dissolution rate of effective components and shortens the extraction cycle, but also ensures the stability and consistency of each extraction process, improving the overall quality and efficiency of Chinese herbal medicine component extraction and providing a high-quality raw material foundation for subsequent deep processing.

[0040] Reference Figure 2 and Figure 3The crushing assembly 15 includes a second motor 16, which is mounted in the middle of the crushing box 3. A gear 17 is fixedly connected to the output end of the second motor 16. A crushing cylinder 19 is fixedly connected to the end of the gear 17 away from the second motor 16. A second gear 18 is rotatably connected inside the crushing box 3. The gear 17 and the gear 18 mesh with each other. The crushing cylinder 19 is fixedly connected to the end of the gear 18 away from the second motor 16. Specifically, a pair of crushing cylinders 19 are provided, and the pair of crushing cylinders 19 are symmetrically arranged directly below the feed inlet 4.

[0041] By starting motor 16, its output power drives gear 17 to rotate stably. Gear 17, through its meshing structure with gear 18, drives gear 18 to rotate synchronously, thereby causing a pair of grinding cylinders 19 to rotate in opposite directions. This causes the Chinese medicinal materials to be drawn into the grinding cylinders 19. As the grinding cylinders 19 continue to rotate, the Chinese medicinal materials are squeezed and ground, gradually breaking them into particles of a suitable size for extraction. The internal cell structure is fully destroyed, and the effective components that were originally bound by the cell walls are released and are more easily dissolved. This pulverization method can ensure that the Chinese medicinal materials are crushed to a uniform degree, effectively improving the crushing efficiency and providing an ideal material state for the subsequent extraction process. This not only helps to improve the extraction rate of Chinese medicinal components, but also reduces material waste caused by uneven crushing and optimizes the resource utilization efficiency of the entire Chinese medicinal component separation process.

[0042] Working principle: Chinese medicinal materials are poured into the crushing box 3 through the feed port 4. Then, the motor 16 drives the gear 17 to rotate. The gear 17 drives the gear 18 that meshes with it to rotate, so that a pair of crushing cylinders 19 rotate in opposite directions, crushing the Chinese medicinal materials into a size suitable for extraction. The cell structure is fully destroyed, and the effective ingredients are more easily released.

[0043] When screening the crushed medicinal materials, the motor 9 is started to drive the eccentric block 10 to rotate. The eccentric block 10 continuously hits the bottom of the screen 11, which, together with the spring rod 12, causes the screen 11 to vibrate strongly. During this process, the dust and dregs, due to their small particle size, pass through the screen 11 through the vibration and fall into the collection box 14 below. The larger particles of Chinese medicinal materials fall into the immersion tank 2 through the discharge port 5 through the inclined design of the screen 11, waiting for further processing.

[0044] When the immersion tank 2 is stably controlled, the heat exchange pump 22 in the heat exchange pool 21 delivers the hot or cold medium to the heat exchange ring 23 outside the immersion tank 2 according to the program settings. The temperature detector 24 senses the temperature inside the immersion tank 2 in real time and feeds the data back to the PLC controller 25. The PLC controller 25 then precisely controls the heat exchange pump 22 to maintain a suitable extraction temperature inside the immersion tank 2, ensuring that different Chinese medicine components can be fully dissolved in the optimal temperature environment. A suitable solvent is injected into the immersion tank 2 through the liquid inlet pipe 6. The solvent comes into full contact with the crushed Chinese medicine, and the effective components dissolve in it. After the extraction is completed, the extract flows out through the liquid outlet pipe 7, thus initially completing the separation process of the Chinese medicine components.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
