Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine ingredient detection technology, and more specifically, to a rapid and intelligent detection device for traditional Chinese medicine ingredients. Background Technology

[0002] As an important component of traditional Chinese medicine, the safety and efficacy of Chinese herbal medicines directly affect clinical treatment outcomes and patient health. With the rapid development of the Chinese herbal medicine industry, the demand for testing the components of Chinese herbal medicines is increasing, covering scenarios such as quality control in the planting stage, quality supervision in the production and processing stage, and authenticity verification in the market circulation stage.

[0003] Existing methods for detecting components in traditional Chinese medicine mainly include high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and thin-layer chromatography (TLC). However, these methods have significant limitations: for example, complex sample pretreatment is required before detection, especially for ginseng (for ginsenoside detection), scutellaria baicalensis (for baicalin detection), licorice (for glycyrrhizic acid detection), and angelica sinensis (for ferulic acid detection). These methods require grinding the herbs into powder, adding the extraction solution, and then performing the detection. The procedures are cumbersome, and most of these operations are performed manually, which is time-consuming. This results in a single detection cycle typically taking several hours or even days, making it difficult to meet the needs of rapid detection.

[0004] Based on this, the present invention designs a rapid intelligent detection device for Chinese herbal medicine components to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid and intelligent detection device for Chinese herbal medicine components to solve the problems mentioned in the background art.

[0006] A rapid intelligent detection device for Chinese herbal medicine components includes a pretreatment unit and a detection unit. The pretreatment unit includes a pulverizing device and a grinding device, with the pulverizing device positioned directly above the grinding device. The detection unit includes a detection chamber with an air pump at its top. The air pump has an inlet pipe and an outlet pipe at its inlet and outlet ends, respectively. One end of the inlet pipe is connected to the grinding device. The detection chamber contains two mounting plates arranged vertically, with an extraction tank positioned between them. One end of the outlet pipe passes through the top of the detection chamber and one of the mounting plates, and connects to the top of the extraction tank. The outer surface of the outlet pipe has an injection pipe for introducing an extraction solution into the outlet pipe. A stirring element is mounted on the mounting plate at the top of the extraction tank. A detection mechanism is located at the bottom of the detection chamber.

[0007] By crushing and grinding, the samples of traditional Chinese medicine are pretreated. The air pump, extraction tank, stirring device and detection mechanism work together to complete the extraction and detection of components, and build an integrated framework of "pretreatment-extraction-detection". This solves the problem of disconnect between pretreatment and detection and scattered operation in traditional detection, and lays the foundation for efficient subsequent detection.

[0008] Preferably, the crushing device includes a crushing cylinder, the interior of which is hollow, a feed hopper is provided on the outer surface of the crushing cylinder, a rotating shaft is rotatably mounted inside the crushing cylinder, a plurality of crushing blades are evenly arranged on the outer surface of the rotating shaft, the cross-section of the crushing blades is T-shaped, and a motor is provided on one side of the crushing cylinder.

[0009] The structure of the pulverizing device was clarified. The T-shaped cross-section pulverizing blades can enhance the shearing and crushing ability of Chinese herbal medicines. The motor drives the rotating shaft to rotate the blades at high speed, which can quickly crush block and flaky Chinese herbal medicines, shorten the sample pretreatment time, avoid the impact of excessively large sample particles on the subsequent grinding efficiency, and provide raw materials that meet the requirements for fine grinding.

[0010] Preferably, the grinding device includes a grinding cylinder, the interior of which is hollow. One end of the air inlet pipe is connected to the outer surface of the grinding cylinder. A second motor is installed at the bottom of the grinding cylinder. An installation plate is fixedly mounted on the output shaft of the second motor. The installation plate has an I-shaped cross-section. Multiple grinding wheels are evenly rotatably mounted between the upper top plate and the lower bottom plate on the outer side of the installation plate. The outer surfaces of the multiple grinding wheels have a certain gap with the inner surface of the grinding cylinder. Two T-shaped scrapers are fixedly mounted in a circular array on the lower plate of the installation plate. The bottom of both scrapers is in contact with the bottom of the interior of the grinding cylinder.

[0011] The structure of the grinding device was clarified. The I-shaped mounting plate drives the grinding wheel to rotate along the inner wall of the grinding cylinder, and the gap between the grinding wheel and the cylinder wall is used to achieve fine grinding of the pulverized sample. The T-shaped scraper can scrape up the sample accumulated at the bottom of the grinding cylinder to ensure uniform grinding of the sample, improve the grinding sufficiency, reduce sample waste, and push the sample to the air inlet end of the air inlet pipe to ensure that the sample particles entering the subsequent extraction stage are small and uniform, thereby improving the component extraction efficiency.

[0012] Preferably, a support block is provided at the top of the grinding cylinder, and an arc-shaped groove is opened at the top of the support block. The crushing cylinder is disposed in the arc-shaped groove at the top of the support block, and a discharge pipe is provided inside the support block. The two ends of the discharge pipe are respectively connected to the outer surface of the crushing cylinder and the top of the grinding cylinder.

[0013] The arc-shaped groove of the support block enables stable installation of the crushing cylinder. The discharge pipe directly connects the crushing cylinder and the grinding cylinder, allowing the crushed sample to enter the grinding device quickly and without residue. This avoids spillage or contamination of the sample during transfer, ensures the continuity of the pretreatment process, and further shortens the overall testing cycle.

[0014] Preferably, a spiral heating wire is provided between the two mounting plates, and the heating wire is disposed on the outer surface of the extraction tank. The stirring component includes a micro motor disposed on the surface of one of the mounting plates. The output shaft of the micro motor is fixedly mounted with a stirring shaft. The bottom end of the stirring shaft passes through the mounting plate and extends into the extraction tank. A stirring rod is provided on the outer surface of the stirring shaft.

[0015] The extraction vessel is wrapped with a spiral heating wire, which can heat the sample and extraction solution inside the vessel according to the extraction requirements, promoting the dissolution of Chinese herbal medicine components. The micro motor drives the stirring shaft and stirring rod to rotate, so as to achieve full mixing of materials in the extraction vessel, accelerate the dissolution of components, solve the problems of "slow dissolution and insufficient dissolution" in traditional extraction, and improve extraction efficiency and extraction rate.

[0016] Preferably, the detection mechanism includes a first fixed plate and a second fixed plate, both disposed within the detection chamber. The first fixed plate and the second fixed plate are arranged vertically. A water pump is disposed on the upper surface of the first fixed plate. The inlet and outlet ends of the water pump are respectively provided with an inlet pipe and an outlet pipe. The inlet end of the inlet pipe passes through the first fixed plate and the mounting plate in sequence and is connected to the bottom of the extraction tank. Two connecting plates are symmetrically distributed and fixedly installed between the first fixed plate and the second fixed plate. A chromatographic column is disposed between the two connecting plates. One end of the outlet pipe passes through the first fixed plate and is connected to one end of the chromatographic column. The other end of the chromatographic column is provided with a connecting pipe. An ultraviolet-visible light detector and a mass spectrometer detector are respectively disposed at the bottom of the detection chamber. The other end of the connecting pipe is connected to the ultraviolet-visible light detector, and the ultraviolet-visible light detector and the mass spectrometer detector are connected through a connecting pipe.

[0017] The extract is pumped to a chromatographic column for separation, and then detected sequentially by a UV-Vis detector and a mass spectrometer. The two detectors work together to achieve preliminary qualitative and quantitative analysis of the components through the UV-Vis detector, and to obtain more accurate structural information of the components through the mass spectrometer, thereby improving the accuracy and reliability of the detection results and meeting the needs of detecting complex Chinese herbal medicine components.

[0018] Preferably, the water inlet pipe is equipped with a filter for filtering solid impurities in the extract liquid inside the extraction tank.

[0019] A filter is installed in the water inlet pipe to filter out solid impurities in the extract, preventing impurities from entering the chromatographic column and clogging the pipeline or affecting the detection accuracy. This ensures the normal operation of the internal components of the detection unit, reduces the frequency of equipment maintenance, and extends the service life of the equipment.

[0020] Preferably, the detection chamber is equipped with a data processing unit, which includes a microprocessor, an A / D converter, and a data storage device. The signal output terminals of the ultraviolet-visible light detector and the mass spectrometer detector are both connected to the input terminal of the A / D converter via signal lines. The output terminal of the A / D converter is connected to the input terminal of the microprocessor. The microprocessor is bidirectionally electrically connected to the data storage device. The outer surface of the detection chamber is equipped with a touch screen and a data interface. The signal terminal of the touch screen is bidirectionally connected to the microprocessor, and the data interface is connected to the communication terminal of the microprocessor. The microprocessor is electrically connected to the control terminals of the air pump, motor one, motor two, micro motor, water pump, and heating wire, respectively, for receiving and analyzing the detection data from each detector, and controlling the operating status of each actuator according to a preset program or user instructions.

[0021] The device automatically acquires, converts, and analyzes detection data through a microprocessor and an A / D converter. The data storage device stores the detection results, and the touch screen and data interface enhance the operability and data interaction capabilities of the device. At the same time, the microprocessor centrally controls each actuator (air pump, motor, etc.) to achieve "automatic operation - automatic data processing - result visualization", reducing manual intervention, lowering operational errors, and truly realizing "intelligent detection".

[0022] Compared with the prior art, the advantages of this invention are:

[0023] 1. This invention establishes an integrated automated system of "preprocessing-extraction-detection-data processing" by setting up a preprocessing unit, a detection unit, and a detection mechanism, and cooperating with a data processing unit. This solves the problems of complex sample preprocessing, extensive manual operation, and long processing time in the prior art, significantly shortening the detection cycle and improving detection efficiency and result accuracy.

[0024] 2. This invention, by installing a filter on the inlet pipe, can filter solid impurities in the extract in the extraction tank, preventing impurities from entering the chromatographic column and clogging the pipeline or affecting the detection accuracy. This solves the problem in the prior art that impurities in the extract can easily interfere with detection and damage the equipment, ensuring the normal operation of the testing institution, reducing the frequency of equipment maintenance, and extending the service life of the equipment.

[0025] 3. This invention solves the problems of "slow dissolution and insufficient dissolution" in the extraction process of existing technologies by setting a spiral heating wire and a stirring component in the detection chamber. The heating wire can heat as needed to promote the dissolution of components, and the stirring component can achieve full mixing of materials and accelerate dissolution. This effectively improves the extraction efficiency and extraction rate, and lays the foundation for subsequent accurate detection.

[0026] 4. This invention connects the microprocessor of the data processing unit to the control terminals of the air pump, motor one, motor two, micro motor, water pump, and heating wire respectively. Combined with the touch screen and data interface, it realizes the automated operation of each execution component, automatic collection and analysis of detection data, and visualization output of results. This solves the problems of excessive manual intervention, large operation error, and inconvenient data interaction in the prior art, truly realizing "intelligent detection" and reducing the difficulty of operation.

[0045] Working principle of the invention:

[0046] I. Pre-processing unit: Sample crushing and fine grinding

[0047] The pretreatment unit, through the cooperation of a pulverizing device and a grinding device, transforms raw Chinese herbal medicines into fine powder that meets extraction requirements. First, the operator feeds lumps or flakes of Chinese herbal medicine into the pulverizing cylinder 8 through the feed hopper 9 on the outer surface of the pulverizing cylinder 8. The motor 12 is then started, and its output shaft drives the rotating shaft 10 inside the pulverizing cylinder 8 to rotate at high speed. The T-shaped pulverizing blades 11 on the outer surface of the rotating shaft 10 rotate accordingly, quickly and initially pulverizing large pieces of the sample. The pulverized sample is then discharged through the discharge pipe 19 inside the support block 18 (the support block 18 has an arc-shaped groove at its top that fixes the pulverizing cylinder 8). To ensure structural stability, the sample is directly fed into the grinding cylinder 13 below. After entering the grinding stage, the motor 14 at the bottom of the grinding cylinder 13 starts, driving the I-shaped mounting plate 15 to rotate. The grinding wheel 16 on the outside of the mounting plate 15 rolls along the inner wall of the grinding cylinder 13, using the gap between the grinding wheel 16 and the cylinder wall to perform fine grinding on the sample. At the same time, the T-shaped scraper 17 on the lower plate of the mounting plate 15 rotates with the mounting plate 15, scraping up the sample accumulated at the bottom of the grinding cylinder 13, ensuring that the sample is ground evenly and pushed to the air inlet end of the air inlet pipe 3, in preparation for subsequent transportation.

[0048] II. Sample Delivery and Extraction: Air Pump Delivery and Heating / Stirring for Dissolution

[0049] After pretreatment, the air pump 2 on the top of the detection chamber 1 is started, and the fine powder in the grinding cylinder 13 is drawn out through the air inlet pipe 3 (one end of which is connected to the outer surface of the grinding cylinder 13), forming a negative pressure airflow. The sample powder is carried by the airflow through the air outlet pipe 4 (which passes through the top of the detection chamber 1 and the upper mounting plate 5) and enters the extraction tank 6 (installed between two upper and lower mounting plates 5). At the same time, the extraction solution (such as ethanol or distilled water) can be injected into the air outlet pipe 4 through the liquid injection pipe 7 on the outer surface of the air outlet pipe 4. After mixing with the sample powder, they enter the extraction tank 6 together. Then, the spiral heating wire 20 wrapped around the outer surface of the extraction tank 6 between the two mounting plates 5 is started, and the mixture of "sample-solution" is heated according to the preset program to promote the dissolution of effective components. The micro motor 21 on the upper mounting plate 5 drives the stirring shaft 22 and stirring rod 23 to rotate, which fully stirs the mixture, breaks the laminar flow state of the liquid, accelerates the dissolution of components, and improves the extraction efficiency and extraction rate.

[0050] III. Testing Institution: Extract Filtration, Separation and Dual Detector Analysis

[0051] After extraction, the water pump 26 on the fixed plate 24 (located at the bottom of the detection chamber 1, arranged vertically with the fixed plate 25) is started, and the extract is drawn through the water inlet pipe 27 (passing through the fixed plate 24, the mounting plate 5 below, and connected to the bottom of the extraction tank 6). The extract first passes through the filter 34 on the water inlet pipe 27 to filter out incompletely ground solid impurities, avoiding blockage of the pipeline or interference with detection. The filtered extract is then transported through the water outlet pipe 28 to the chromatographic column 30 (fixed on the connecting plate 29 between the fixed plate 24 and the fixed plate 25). The adsorption-desorption difference of the packing material in the chromatographic column 30 is used to separate the components and impurities in the extract. The separated components first enter the ultraviolet-visible light detector 32 through the connecting pipe 31 to detect the absorption intensity of the components to specific wavelengths of light, completing the preliminary qualitative and quantitative analysis. Then, they enter the mass spectrometer 33 to obtain precise information such as the molecular structure of the components by analyzing the mass-to-charge ratio. The dual detectors work together to improve the accuracy of the detection results.

[0052] IV. Data Processing Unit: Intelligent Control and Result Output

[0053] During the detection process, the analog signals from the UV-Vis detector 32 and the mass spectrometer detector 33 are transmitted to the A / D converter via signal lines. After being converted into digital signals, they are sent to the microprocessor. The microprocessor analyzes and processes the digital signals (such as comparing them with standard spectra in the data storage) and stores the detection results in the data storage. Operators can view the visualized detection results (such as component names and contents) through the touch screen on the outer surface of the detection chamber 1, and can also input commands (such as setting the heating temperature) through the touch screen. The data interface on the outer surface of the detection chamber 1 can export the results to external devices. At the same time, the microprocessor is electrically connected to the control terminals of the air pump 2, motor 12, motor 14, micro motor 21, water pump 26, and heating wire 20, respectively, and controls the operation of each component according to the preset program or user commands to achieve full automation, reduce manual intervention, and shorten the detection cycle.
