Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a device for pulverizing and ultrasonically extracting traditional Chinese medicine. Background Technology

[0002] The pulverization and extraction of medicinal herbs are crucial steps in the processing of traditional Chinese medicine (TCM), playing a vital role in improving the utilization rate of active ingredients and ensuring drug quality. Pulverization increases the surface area of ​​medicinal herbs, facilitating the dissolution of active ingredients and also benefiting subsequent extraction and decoction processes. Extraction separates and obtains the active components from TCM herbs, providing raw materials for the preparation of various TCM formulations.

[0003] Pulverization technology plays a crucial role in the processing of traditional Chinese medicine (TCM). Pulverization disrupts the cellular structure of medicinal materials, increasing their surface area and promoting the leaching and extraction of active ingredients. Pulverized herbs are also easier to mix with other components, improving the uniformity and stability of the medicine. Furthermore, pulverization aids in the drying and storage of medicinal materials, extending their shelf life. Extraction technology is the key step in separating and obtaining the active ingredients from TCM herbs. Extraction techniques allow for the selection of appropriate solvents and extraction methods based on the characteristics of the herbs to maximize the extraction of active ingredients. After extraction, the herbs undergo separation and purification to obtain high-purity active ingredients, providing raw materials for the preparation of various TCM formulations.

[0004] However, most existing Chinese medicinal herb extraction devices on the market are not ideal in terms of extracting active ingredients. This not only limits the full utilization of Chinese medicinal herb resources, but also indirectly affects the extraction and purification process of active ingredients and other important components.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a device for pulverizing and ultrasonically extracting Chinese medicinal materials to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] An ultrasonic extraction device for pulverizing Chinese medicinal materials includes a small ball mill. A first conveying auger is connected to the feed inlet of the small ball mill. An inlet is provided above the first conveying auger. Two sets of pulverizing rollers are provided inside the inlet, with two rollers in each set. A second conveying auger is connected to the discharge outlet of the small ball mill. A discharge pipe is provided below the second conveying auger and is connected to a processing tank. An ultrasonic transducer is provided inside the processing tank and is electrically connected to an ultrasonic generator. A filter box is provided below the processing tank.

[0009] Furthermore, in order to ensure that the material is subjected to uniform force and improve extraction efficiency, a stirring shaft is installed inside the processing tank, and a stirring rod is connected to the stirring shaft. One end of the stirring shaft passes through the processing tank and is connected to a rotary motor.

[0010] Furthermore, to ensure that solid impurities in the extract are completely removed, the filter box is equipped with three filter screens, with sliders connected to the outside of the filter screens. The filter box is equipped with a sliding groove, and the sliders match the sliding grooves. One end of the filter screen passes through the filter box and is connected to a baffle. An oil outlet pipe is provided at the bottom of the filter box.

[0011] Furthermore, to facilitate the installation and removal of the filter screen, and to make it easier to clean and replace the filter screen, the upper and lower sides of the baffle are provided with limiting grooves. A limiting plate is slidably connected inside the limiting grooves. A clamping plate is provided inside the limiting plate. The limiting plate is provided with a threaded hole. A screw is threaded inside the threaded hole. The screw is rotatably connected to the clamping plate. A limiting rod is fixedly connected to the clamping plate. The limiting rod is connected through the limiting plate.

[0012] Furthermore, the first and second conveying augers are driven by the first drive motor, and the crushing roller is driven by the second drive motor.

[0013] Furthermore, the ultrasonic generator is mounted on the filter box, and a discharge pipe is connected to one side of the treatment tank. The discharge pipe is connected to the input end of the pressure pump, and the output end of the pressure pump is connected to the filter box through a connecting pipe.

[0014] Furthermore, the top of the treatment tank is equipped with a liquid injection port.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) By installing two sets of crushing rollers inside the feed inlet, preliminary and secondary crushing can be achieved, gradually breaking large pieces of Chinese medicinal materials into smaller particles, providing finer raw materials for subsequent small ball mill processing, and further crushing the initially crushed Chinese medicinal materials into micron-sized particles by the small ball mill. The high-efficiency grinding capacity of the small ball mill can ensure that the Chinese medicinal materials are fully crushed, increase the release area of ​​effective components, and improve extraction efficiency. Ultrasonic treatment can accelerate the rupture of cell walls, promote the dissolution of effective components, and improve extraction efficiency and purity. This device has a compact structure, is easy to operate, and is suitable for small-scale industrial production.

[0017] (2) By setting up three filter screens with progressively smaller pore sizes from top to bottom, a step-by-step filtration system is formed. The first-stage filter screen removes larger particles, the second-stage filter screen removes medium-sized particles, and the third-stage filter screen removes tiny particles. This design ensures that solid impurities in the extract are completely removed, improving the purity of the extract. Furthermore, by connecting sliders to the outside of the filter screens, they can be easily installed and removed, facilitating cleaning and replacement, and ensuring the continuity of the filtration effect.

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.

[0026] According to an embodiment of this utility model, a device for pulverizing and ultrasonically extracting Chinese medicinal materials is provided.

[0027] Example 1

[0028] like Figures 1-4 As shown, the ultrasonic extraction device for pulverizing Chinese medicinal materials according to an embodiment of this utility model includes a small ball mill 1. The small ball mill 1 is a cylindrical or spherical container containing grinding media (agate balls) and the material to be ground. A first conveying auger 2 is connected to the feed inlet of the small ball mill 1. An inlet 3 is provided above the first conveying auger 2. Two sets of pulverizing rollers 4 are provided inside the inlet 3. Each set of pulverizing rollers 4 consists of two rollers. The distance between the two rollers of the lower pulverizing roller 4 is smaller than the distance between the two rollers of the upper pulverizing roller 4. A second conveying auger 2 is connected to the discharge outlet of the small ball mill 1. The auger 5, the first conveying auger 2 and the second conveying auger 5 are driven by the first drive motor 25, the crushing roller 4 is driven by the second drive motor 26, the discharge pipe 6 is provided below the second conveying auger 5 and is connected to the processing tank 7, the bottom of the processing tank 7 is provided with an ultrasonic transducer 8 and is electrically connected to an ultrasonic generator 9, the processing tank 7 is provided with a stirring shaft 11 and a stirring rod 12 is connected to the stirring shaft 11, one end of the stirring shaft 11 passes through the processing tank 7 and is connected to a rotary motor 13, and the top of the processing tank 7 is provided with a liquid injection port 30. Through the above scheme, large pieces of Chinese medicinal materials are placed into the feed inlet 3, and the Chinese medicinal materials are crushed by two sets of crushing rollers 4, so that the large pieces of Chinese medicinal materials are gradually broken into smaller particles. The crushed Chinese medicinal materials are conveyed to the small ball mill 1 through the first conveying auger 2, and the Chinese medicinal materials are ground into smaller particles by the small ball mill 1. Then, the Chinese medicinal materials particles are transported to the processing tank 7 through the second conveying auger 5. Then, the extraction solvent is introduced into the processing tank 7 through the liquid injection port 30. The ultrasonic generator 9 is started, and ultrasonic waves are emitted into the processing tank 7 through the ultrasonic transducer 8. The ultrasonic waves generate cavitation effect and mechanical action in the oil extraction solvent, which can effectively break the cell walls of the Chinese medicinal materials. Then, the rotary motor 13 is started, which drives the stirring rod 12 to rotate, so that the material is evenly stressed.

[0029] like Figures 1-4As shown, a filter box 10 is located below the processing tank 7. Inside the filter box 10 are three filter screens 14, with the aperture of the three filter screens decreasing from top to bottom. A slider 15 is connected to the outside of each filter screen 14. A sliding groove 16 is located inside the filter box 10, and the slider 15 matches the sliding groove 16. One end of each filter screen 14 passes through the filter box 10 and connects to a baffle 17. An oil outlet pipe 18 is located at the bottom of the filter box 10. Limiting grooves 19 are located on the upper and lower sides of the baffle 17, and the limiting grooves 19 are fixedly connected to the filter box 10. The limiting grooves 19 slide within their respective sides. A limiting plate 20 is connected, and a clamping plate 21 is provided on the inner side of the limiting plate 20. A threaded hole 22 is provided on the limiting plate 20, and a screw 23 is threadedly connected inside the threaded hole 22. The screw 23 is rotatably connected to the clamping plate 21. A limiting rod 24 is fixedly connected to the clamping plate 21, and the limiting rod 24 is connected through the limiting plate 20. An ultrasonic generator 9 is mounted on the filter box 10. A discharge pipe 27 is connected to one side of the processing tank 7, and the discharge pipe 27 is connected to the input end of a pressure pump 28. The output end of the pressure pump 28 is connected to the filter box 10 via a connecting pipe 29. Both the oil outlet pipe 18 and the discharge pipe 27 are equipped with solenoid valves. Using the above scheme, the pressure pump 28 is started to extract the extract from the processing tank 7 and transfer it to the filter box 10. The extract is filtered sequentially through three filter screens 14 inside the filter box 10. The pore size of the three filter screens 14 decreases from top to bottom, achieving multi-stage filtration. This ensures that solid impurities in the extract are completely removed, improving the purity of the extract. When the filter screen 14 needs to be cleaned, the screw 23 can be rotated to move the clamping plate 21 away from the baffle 17. Then, by sliding the clamping plate 21 to one side of the baffle 17, the baffle 17 can be pulled out, allowing the filter screen 14 to be removed for easy cleaning or replacement. After cleaning, the slider 15 can be placed inside the slide groove 16 to make the baffle 17 fit tightly against the filter box 10. Then, by moving the limiting plate 20, the clamping plate 21 can be moved. Then, by rotating the screw 23, the clamping plate 21 can be fixed to the baffle 17, thus ensuring the stability of the filter screen 14. After filtration, the liquid can be discharged through the oil outlet pipe 18, and the discharged liquid can be collected through the collection tank (not shown in the figure).

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, two sets of crushing rollers 4 are provided inside the feed inlet 3, enabling preliminary and secondary crushing. Large pieces of Chinese medicinal materials are gradually broken down into smaller particles, providing finer raw materials for subsequent processing in the small ball mill 1. Furthermore, the small ball mill 1 further crushes the initially crushed Chinese medicinal materials to micron-level particles. The high-efficiency grinding capacity of the small ball mill 1 ensures that the Chinese medicinal materials are fully crushed, increasing the release area of ​​effective components and improving extraction efficiency. Ultrasonic treatment further accelerates cell wall rupture, promotes the dissolution of effective components, and improves extraction efficiency and purity. This device is compact, easy to operate, and suitable for small-scale industrial production. Additionally, by setting three filter screens 14, with pore sizes decreasing from top to bottom, a step-by-step filtration system is formed. The first-stage filter screen 14 removes larger particles, the second-stage filter screen 14 removes medium-sized particles, and the third-stage filter screen 14 removes tiny particles. This design ensures that solid impurities in the extract are completely removed, improving the purity of the extract. Furthermore, by connecting a slider 15 to the outside of the filter screen 14, the filter screen 14 can be easily installed and removed, making it easy to clean and replace, and ensuring the continuity of the filtration effect.
