Description

Technical Field

[0001] The utility model belongs to the technical field of traditional Chinese medicine extraction, and specifically relates to a traditional Chinese medicine extraction device based on the acoustic chemical effect and mixed micro gas nuclei. Background Technique

[0002] Traditional Chinese medicine extraction technology is widely used in the field of traditional Chinese medicine pharmaceutical production. The extraction device is one of the key equipment in traditional Chinese medicine extraction. Ultrasonic extraction technology is increasingly applied in the field of traditional Chinese medicine pharmaceutical production. Currently, most extraction methods have the following deficiencies:

[0003] 1. Simply relying on body waves cannot achieve multi-dimensional drug extraction, and the extraction efficiency is low.

[0004] 2. The number of micro gas nuclei in the solution is beneficial to enhancing the cavitation effect. However, currently, traditional Chinese medicine extraction devices mainly consider optimizing the sound source excitation parameters to improve the extraction efficiency, without considering the influence of the gas content in the solution.

[0005] 3. It is not convenient to clean. The impurities generated during decocting will adhere to the tank wall and bottom, making it difficult to clean. Content of the Utility Model

[0006] In view of the above deficiencies in the background technique, the utility model proposes a traditional Chinese medicine extraction device based on the acoustic chemical effect and mixed micro gas nuclei, which solves the problems of inability to perform multi-dimensional extraction, low extraction efficiency, and inconvenience in cleaning.

[0007] The technical solution of this application is as follows:

The regular-shaped ultrasonic transducer is vertically incident, which can allow more energy to enter the solution. The irregular-shaped transducer forms an angle with the side wall of the tank body, which can ensure a longer transmission distance of the ultrasonic guided wave while enabling more energy to leak into the solution, realizing multi-dimensional drug extraction and thus improving the extraction efficiency.

[0010] Furthermore, the irregular-shaped ultrasonic transducer includes a first base in the shape of a wedge, and the bottom surface of the first base is attached to the side wall of the tank body.

[0011] Furthermore, the regular-shaped ultrasonic transducer includes a second base in the shape of a cylinder, and the bottom surface of the second base is attached to the bottom of the tank body.

[0012] Furthermore, a piezoelectric ceramic and a counterweight are connected to both the first base and the second base, and a metal electrode is connected to the counterweight.

[0013] Furthermore, both the irregular-shaped ultrasonic transducer and the regular-shaped ultrasonic transducer are piezoelectric type, which can respond quickly while having high sensitivity, and can convert energy in real time to achieve the effect of ultrasonic extraction.

[0014] Furthermore, a heat insulation layer is provided on the outer wall of the tank body to maintain the temperature of the solution and reduce heat loss.

[0015] Furthermore, the microbubble generator is disposed at the bottom of the tank body, and a screen is provided between the microbubble generator and the material basket, which can intercept impurities generated during the extraction of traditional Chinese medicine and is used for secondary interception of sediments.

[0016] Furthermore, a water inlet is provided at the top of the tank body, and a water outlet is provided at the bottom of the tank body.

[0017] Furthermore, a bracket is provided at the bottom of the tank body to support the tank body for the ultrasonic transducer to be connected to the bottom of the tank body.

[0019] 1. Compared with the traditional ultrasonic extraction technology, the combination of body waves and guided waves can be used to achieve multi-dimensional drug extraction, improving the extraction effect;

[0020] 2. The microbubbles generated by the microbubble generator can improve the cavitation effect and further enhance the extraction effect.

[0021] 3. While extracting the drug, the cavitation effect generated by the leakage of ultrasonic guided waves on the inner wall of the device can remove the residual drug on the inner wall of the tank or the parts that are difficult to access.

[0022] 4. The ultrasonic transducer components are all installed outside the tank body, which is convenient for disassembly.

The regular-shaped ultrasonic transducer 11 includes a cylindrical base. The bottom surface of the base is attached to the bottom of the tank body 1. The ultrasonic waves generated by the regular-shaped ultrasonic transducer 11 are directly vertically incident into the solution along the cylindrical base, allowing more energy to enter the solution.

[0056] Preferably, compared with the method of adding ultrasonic vibration in the liquid, the ultrasonic transducer assembly is directly installed on the outer wall of the tank, which is simple to operate, convenient to manufacture, and has a lower cost.

[0060] Based on the above embodiments, as a preferred embodiment, both the irregular-shaped ultrasonic transducer 3 and the regular-shaped ultrasonic transducer 11 are piezoelectric, which can respond quickly while having high sensitivity and can convert energy in real time.

[0061] Specifically, the microbubbles generated by the microbubble generator 8 can directly serve as the conditions for the cavitation effect, thereby enhancing the cavitation effect and improving the extraction rate.

[0067] The working principle of the present invention is as follows:

[0068] The regular-shaped ultrasonic transducer in the shape of a cylinder is installed at the bottom of the tank body, and the generated ultrasonic waves vertically enter the solution, and the cavitation effect is realized through body waves to complete the extraction. The irregular-shaped ultrasonic transducer in the shape of a wedge emits ultrasonic waves at an angle with the side wall of the tank body. When the ultrasonic waves propagate along the tank body, due to the limitation of the boundary conditions of the tank body, phenomena such as reflection and refraction will occur at the tank body wall surface, thereby generating ultrasonic guided waves. The ultrasonic guided waves leak into the liquid to form leaky ultrasonic guided waves. Microscopic gas nuclei generate cavitation effects under the action of the leaky ultrasonic guided waves, generating high temperature and high pressure, achieving the effect of extracting traditional Chinese medicine, and at the same time, the attached substances on the inner wall of the tank body can be removed by using the leaky ultrasonic guided waves. The cavitation bubbles in the solution are the key to generating cavitation conditions, and the cavitation effect directly affects the extraction effect. Therefore, using a microbubble generator to generate microbubbles can directly improve the cavitation effect to increase the extraction rate.

[0069] Compared with the traditional ultrasonic extraction technology, the present utility model can achieve multi-dimensional drug extraction by combining body waves and guided waves, improving the extraction effect; the microbubbles generated by the microbubble generator can enhance the cavitation effect and further improve the extraction effect; while extracting drugs, the cavitation effect generated by the leakage of ultrasonic guided waves on the inner wall of the device can remove the residual drugs on the inner wall of the tank or parts that are difficult to access. The ultrasonic transducer components are all installed outside the tank for easy disassembly; the regular-shaped ultrasonic transducer in the shape of a cylinder installed at the bottom of the tank generates ultrasonic waves that directly enter the solution to produce cavitation, and the irregular-shaped ultrasonic transducer in the shape of a wedge on the side wall of the tank realizes cavitation through the leakage of ultrasonic guided waves. The regular-shaped ultrasonic transducer in the shape of a cylinder is vertically incident, allowing more energy to enter the solution. The incident angle of the irregular-shaped transducer in the shape of a wedge forms an angle with the side wall of the tank, which can ensure that the transmission distance of the ultrasonic guided wave is farther and more energy can leak into the solution, thereby increasing the cavitation intensity.
