Description

Technical Field

[0001] The present invention mainly relates to the field of traditional Chinese medicine pharmacy, and more specifically, to a device and method for ultrasonic atomization purification of traditional Chinese medicine liquid to prepare particles using photovoltaic power generation. Background Art

[0002] Traditional Chinese medicine (TCM) is a drug that uses traditional Chinese medical theory to guide its collection, processing, and preparation, explaining its mechanisms of action and guiding its clinical application. TCM primarily originates from natural medicinal products and their processed products, including botanicals, animal medicines, minerals, and some chemical and biological products. Because TCM is primarily based on botanicals, there's a saying that "all medicines are based on herbs."

[0003] Traditional Chinese medicine (TCM) has a long history. For thousands of years, through practice and continuous understanding in the process of battling illness, working people have gradually accumulated a wealth of medical knowledge. TCM has also played a significant role in the treatment of certain diseases. As more and more people begin to focus on health and wellness, the market demand for various types of Chinese patent medicines will continue to grow. Many of the TCM medications we see in our daily lives are in the form of granules, which is also a common form of TCM.

[0004] Currently, the purification and granulation of traditional Chinese medicines mainly rely on heating and evaporation. However, the prolonged high-temperature heating not only consumes a large amount of energy, but also causes many active ingredients in the traditional Chinese medicine liquid to lose their effectiveness due to prolonged heating, which greatly affects the efficacy of the traditional Chinese medicine granules. Therefore, how to obtain a high-purity concentrate and prepare traditional Chinese medicine granules while reducing the long-term high-temperature heating of the traditional Chinese medicine liquid is an urgent problem to be solved.

[0005] Ultrasonic atomizers utilize high-frequency electronic oscillations (1.7-2.4 MHz) through the high-frequency resonance of a ceramic atomizer to break up the molecular structure of liquid water, producing a naturally flowing mist. This method requires no heating or chemical reagents. Compared to heated atomization methods, ultrasonic atomizers save 90% of energy. Furthermore, the droplets produced by ultrasonic atomizers are small in size and high in concentration. Summary of the Invention

[0006] In response to the problems existing in the current heating evaporation concentration granulation method, such as high energy consumption, long heating time, and weakened efficacy of traditional Chinese medicine, the purpose of this application is to provide a photovoltaic power generation device and method for ultrasonic atomization purification of traditional Chinese medicine liquid to prepare particles.

[0039] In one embodiment of the present invention, a concentration detector is provided in the diversion tank 25 to monitor the concentration of the drug solution. If the concentration does not meet the standard, the drug solution can be recirculated to the concentration inlet tank 10 to repeat the concentration step. The left side of the diversion tank 25 is connected to the concentration inlet tank 10 via the second water pump 7 and the second solenoid valve 8.

The concentrate solenoid valve 21 is connected to the monitor 18, and the concentration detector is connected to the detection controller 27.

[0040] In one embodiment of the present invention, a concentrated liquid drying device is mainly used to heat and dry a Chinese medicine concentrated liquid to make Chinese medicine granules from the Chinese medicine concentrated liquid. The concentrated liquid drying device includes a granulation tank 17, a particle collection tank 24, an evaporation heater 22, and an air pump 30. An ultrasonic atomizer 14 is provided above the granulation tank 17, an air hole is opened on the top of the granulation tank 17, a temperature sensor is provided on the granulation tank 17, a monitor 18 is connected to the left of the granulation tank 17, and the evaporation heater 22 is connected to the right of the granulation tank 17. An air ejector 19 is provided at the bottom of the granulation tank 17, and the air ejector 19 is connected to the air pump 30 via an air flow solenoid valve 29. The air flow solenoid valve 29 is connected to a detection controller 27. A particle outlet is provided at the bottom of the granulation tank 17, and the particle outlet is connected to the particle collection tank 24. A humidity detector is provided in the particle collection tank 24, and the humidity detector is connected to the detection controller 27.

[0041] As a further preferred embodiment of the present invention, the temperature sensor within the granulation tank 17 monitors a temperature range of 50°C to 150°C. The ultrasonic atomizer 14 utilizes ultrasonic directional pressure to atomize the concentrated liquid into small droplets with a particle size between 10μm and 500μm, achieving a high droplet concentration. The lower inner surface of the granulation tank 17 is constructed of a smooth biomimetic ceramic material, allowing the Chinese medicinal granules to enter the particle collection tank unimpeded, preventing particle accumulation.

[0042] In one embodiment of the present invention, the heat exchange coefficient K in the liquid medicine concentration tank 16 is:

[0043]

[0044] Q: heat load (w); F: area of the liquid concentration tank (m 2 ); ΔT m : Logarithmic mean temperature difference (℃); ρ: Density (kg / m 3 );V c :Volume of the liquid concentration tank (m 3 ); (t2-t1): temperature difference between the inside and outside of the liquid concentration tank (℃).

[0045] The temperature variation equation in the liquid medicine concentration tank 16 is:

[0046]

[0047] ρ: density; e: internal energy per unit mass; v: velocity vector; v 2 : square of velocity; q: conduction heat flux vector; σ: total stress tensor; F: body force per unit mass

[0048] In one embodiment of the present invention, the inlet controller 4, the monitor 18, the detection controller 27, and the heating controller 28 can all communicate wirelessly, and by monitoring the dryness of the particles, they can coordinate various control processes such as heating control, liquid inflow control, and servo motor rotation speed control.

[0049] In order to more clearly illustrate the working process of the above-mentioned device, this embodiment also provides a method for atomizing and purifying particles of the device of this embodiment, which specifically includes the following steps:

[0050] Step 1: The Chinese medicine decoction liquid enters the coarse filter tank 5 through the pipeline. Two funnel-shaped filters are set on the top of the coarse filter tank 5. Sponges are set in the filters to separate some slightly larger Chinese medicine residues from the Chinese medicine liquid. The large-sized Chinese medicine residues filtered out will be cleaned regularly to prevent clogging;

[0051] Step 2: The Chinese medicine liquid after the initial filtration flows down from the funnel filter through the connecting pipe into the fine filtration tank 11. A fine-sized screen is provided on the top of the fine filtration tank 11. The material of the fine-sized screen should be food-grade and high-temperature resistant. It is used to screen the medicinal residue that has not been filtered by the coarse filtration tank 5. The Chinese medicine liquid after double filtration is finally stored in the fine filtration tank 11 for standby use.

[0052] Step 3: The fine filter tank 11 is connected to the concentration inlet tank 10 through the No. 1 solenoid valve 9 and the No. 1 water pump 6. The No. 1 water pump 6 pumps the Chinese medicine filtrate in the fine filter tank 11 into the concentration inlet tank 10. The No. 1 solenoid valve 9 can control the inflow speed of the Chinese medicine filtrate; four jet pipes are provided below the concentration inlet tank 10. The Chinese medicine liquid is injected into the liquid concentration tank 16 in the form of relatively fine water columns, and the water columns form an angle with each other to improve the heat exchange efficiency;

[0053] Step 4: The medicinal liquid concentration tank 16 is provided with a spiral diverter blade 20, and a concentration heating layer is provided outside the concentration tank. The heating layer is electrically connected to the concentration heater 15. The concentration heater 15 is externally connected to a battery that can store photovoltaic power generation energy, which can heat the heating layer and maintain a relatively high temperature in the medicinal liquid concentration tank 16. The medicinal liquid concentration tank 16 is provided with a spiral diverter blade 20 driven by a servo motor 23, which can divert the incident Chinese medicine water column and cut the medicinal liquid so that the medicinal liquid is broken up into a medicinal liquid layer. The medicinal liquid layer is blown to the tank wall by the spiral diverter blade 20, and fully exchanges heat with the tank wall, so that the separated Chinese medicine concentrate flows into the diverter tank 25 connected to the medicinal liquid concentration tank 16, and the water vapor is discharged from the tank body through the air outlet;

[0054] Step 5: A concentration monitoring sensor is provided in the diversion tank 25. When the detected concentration does not meet the requirement, it will be re-pumped into the concentration inlet tank 10 for concentration through the No. 2 water pump 7. When the Chinese medicine concentrate flowing into the diversion tank 25 passes the test and meets the concentration requirement, it will be pumped to the ultrasonic atomizer 14 by the concentrate water pump. The concentration monitoring sensor is connected to the detection controller 27.

[0055] Step 6: The granulation tank 17 is connected to the diversion tank 25 through the concentrate water pump 26 and the concentrate solenoid valve 21. The outside of the granulation tank is provided with an insulation layer to keep the inside of the granulation tank at a high temperature. An ultrasonic atomizer is provided on the top. The concentrated Chinese medicine liquid flowing into the ultrasonic atomizer is ultrasonically atomized into small droplets with a particle diameter between 10μm and 500μm. The droplets will diffuse above the granulation tank for a period of time.

[0056] Step 7: The air ejector 19 provided at the lower portion of the granulation tank 17 is connected to the air pump 30 via the airflow solenoid valve 29. The two air ejectors 19 are installed at a certain angle so that the generated airflow can fully rotate in the granulation tank 17, thereby increasing the contact time with the mist droplets. The air ejector 19 generates a high-speed airflow that fully contacts the mist droplets, thereby taking away the moisture in the mist droplets and fully drying the Chinese medicine particles. A channel is provided at the lower portion of the granulation tank 17 and is connected to the particle collection tank 24, and the dried Chinese medicine particles fall along the channel.

[0057] After being fully dried, the Chinese medicinal granules fall into a granule collection tank 24. A humidity sensor is installed within this tank. After collecting a certain amount of Chinese medicinal granules, the humidity sensor monitors the dryness of the granules. If the granules are sufficiently dry, they are processed into the final product. If the granules are too wet, the detection controller 27 wirelessly communicates with the inlet controller 4, the monitor 18, and the heating controller 28 to coordinate the inlet flow, jet flow, and heating temperature, ensuring that the humidity of the final product—the Chinese medicinal granules—meets production standards.

[0058] In summary, the photovoltaic power generation device for ultrasonic atomization, purification and granulation of traditional Chinese medicine liquid provided by the present invention utilizes a photovoltaic power generation system for power supply, which greatly reduces the consumption of fossil energy; it also adopts an ultrasonic atomizer to atomize the medicine liquid, which accelerates the evaporation of water in the droplets and greatly improves the efficiency of granulation; through multi-stage traditional Chinese medicine atomization concentration, the heating time of the traditional Chinese medicine liquid is greatly reduced, thereby protecting the efficacy of the traditional Chinese medicine.

[0059] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

10. A method for purifying particles using the device according to claim 1, characterized in that: The following steps are involved: Step 1: The Chinese medicine decoction liquid enters the medicine residue filtering device through a pipeline for filtration, and the Chinese medicine liquid filtered by the medicine residue filtering device is stored in the medicine residue filtering device for standby use; Step 2: The Chinese medicinal liquid in the medicinal residue filtering device flows into the concentration inlet tank (10), and the Chinese medicinal liquid in the concentration inlet tank (10) is injected into the medicinal liquid concentration tank (16) in the form of a relatively fine water column through the fine jet tube; Step 3: The concentrated heating layer of the liquid medicine concentration tank (16) is heated by the concentrated heater (15), and the spiral diverter blades (20) divert the injected liquid medicine and cut the liquid medicine so that the liquid medicine is broken up into liquid medicine layers. The liquid medicine layers fully exchange heat with the tank wall, thereby separating the Chinese medicine concentrate and water vapor; the Chinese medicine concentrate flows into the diverter tank connected to the liquid medicine concentration tank (16), and the water vapor is discharged from the liquid medicine concentration tank (16) through the air outlet; Step 4: A concentration detector is provided in the diversion tank (25). When the detected concentration does not meet the requirements, the concentrated Chinese medicine liquid will be pumped back into the concentration inlet tank (10) for concentration through the second water pump (7). When the concentrated Chinese medicine liquid flowing into the diversion tank (25) passes the test and meets the concentration requirements, it will be pumped to the ultrasonic atomizer (14) by the concentrated liquid water pump; Step 5: The granulation tank (17) is connected to the diversion tank (25) through a pipeline, and the ultrasonic atomizer (14) provided on the top ultrasonically atomizes the concentrated Chinese medicine solution flowing into the ultrasonic atomizer (14) into small droplets; Step 6: The air ejector (19) provided at the lower portion of the granulation tank (17) generates a high-speed airflow, which fully contacts the mist droplets, thereby removing moisture from the mist droplets and fully drying the Chinese medicine particles; the fully dried Chinese medicine particles fall into the particle collection tank (24) for collection.
