Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical raw material testing technology, specifically a chemical impurity analysis and testing device. Background Technology
[0002] Chemical products are essential substances in modern industrial production and daily life. Various chemicals, manufactured through chemical reactions or physical changes, are widely used in many fields such as industry, agriculture, medicine, and daily necessities. Chemical impurity analysis and testing refers to the process of identifying, quantifying, and qualitatively analyzing non-target substances in chemical products or raw materials during chemical production. These impurities may be present in the raw materials or introduced during the production process. The types and contents of impurities directly affect the quality and performance of chemical products, and may even cause corrosion to production equipment or lead to safety accidents. Therefore, chemical impurity analysis and testing is an important means to ensure that chemical products meet quality standards and ensure production safety.
[0003] Existing devices directly deliver the extracted sample to the analyzer through pressure balance. However, the sample flow rate cannot be controlled at this point. Flow rates that are too fast or too slow may prevent the analyzer from accurately capturing impurity signals in the sample, thus affecting the accuracy of the test results.
[0004] Therefore, those skilled in the art have provided a chemical impurity analysis and detection device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide a chemical impurity analysis and detection device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A chemical impurity analysis and detection device includes an experimental table, an adjustment component on the top of the experimental table, a support rod fixedly connected to one side of the top of the experimental table, a container fixedly connected to the top of the support rod, a cover plate movably connected to the top of the container, a sealing plug fixedly connected to the bottom of the cover plate, and a feed pipe fixedly connected to one side of the container.
[0008] As a further embodiment of this utility model: the adjustment component includes a fixed frame, a servo motor, a lead screw, a slider, and an anti-detachment disc. The fixed frame is fixedly connected to the top of the experimental table. The servo motor is fixedly connected to the top of the fixed frame. The lead screw is fixedly connected to the transmission end of the servo motor. The slider is slidably connected to the side surface of the lead screw. The anti-detachment disc is fixedly connected to the bottom of the lead screw.
[0009] As a further improvement of this utility model, the adjustment component also includes an L-shaped rod, a sealing baffle, a through hole, a delivery pipe, and a notch. An L-shaped rod is fixedly connected to one side of the slider, and a sealing baffle is fixedly connected to the bottom of the L-shaped rod. A through hole is provided inside the fixing frame, and a delivery pipe is fixedly connected inside the through hole. A notch is provided inside the delivery pipe. By installing the adjustment component, a servo motor drives a lead screw to rotate, thereby moving the slider and the sealing baffle up and down. This achieves precise control of the sample flow rate through the delivery pipe's inlet, ensuring that the sample enters the analyzer at a stable flow rate. This avoids the problem of impurity signals being diluted or missed due to excessively high flow rates, and the problem of excessively long detection times or signal overlap due to excessively slow flow rates. This significantly improves the accuracy and reliability of the detection. The position of the sealing baffle can be flexibly adjusted as needed to adapt to different samples and different detection requirements.
[0010] As a further embodiment of this utility model: a drive motor is fixedly connected to the top of the cover plate, a stirring shaft is fixedly connected to the drive end of the drive motor, and a stirring rod is fixedly connected to the side surface of the stirring shaft.
[0011] As a further embodiment of this utility model: a connecting rod is fixedly connected to one side of the stirring shaft, a fixing rod is fixedly connected to one side of the connecting rod, and a scraper is fixedly connected to one side of the fixing rod.
[0012] As a further embodiment of this utility model: a detection and analysis instrument is fixedly connected to the other side of the conveying pipe, a control panel is fixedly connected to the other side of the detection and analysis instrument, and a display screen is fixedly connected to the other side of the detection and analysis instrument.
[0013] As a further improvement of this utility model: the bottom of the experimental table is fixedly connected with legs, which are distributed in a rectangular array.
[0014] As a further embodiment of this utility model: the sealing baffle is in contact with the inner wall of the notch, the sealing baffle is adapted to the conveying pipe, and the conveying pipe is L-shaped.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. By installing the adjustment component, the servo motor drives the lead screw to rotate, which in turn moves the slider and sealing baffle up and down, achieving precise control of the sample flow rate inside the delivery tube. This ensures that the sample enters the analyzer at a stable flow rate, avoiding the problems of dilution or omission of impurity signals due to excessive flow rate, and excessive detection time or signal overlap due to excessive flow rate. This significantly improves the accuracy and reliability of the detection. The position of the sealing baffle can be flexibly adjusted as needed to adapt to different samples and different detection requirements.
[0017] 2. The drive motor rotates the stirring shaft, and the stirring rod thoroughly stirs the sample and extractant inside the container. This stirring method ensures full contact and mixing between the extractant and the sample, thereby improving extraction efficiency and making the extraction process more efficient and faster. The connecting rod drives the scraper to move on the inner wall of the container through the fixed rod, effectively preventing the sample and extractant from adhering to the container wall, avoiding sample loss and incomplete extraction caused by adhesion, thus ensuring the accuracy of subsequent analysis.

A sealing plug 6 is fixedly connected to the bottom of the cover plate 5. A feed pipe 7 is fixedly connected to one side of the holding cylinder 4. The adjustment assembly 2 includes a fixing frame 201, a servo motor 202, a lead screw 203, a slider 204, and an anti-detachment disc 205. The fixing frame 201 is fixedly connected to... At the top of the experimental table 1, a servo motor 202 is fixedly connected to the top of the fixing frame 201. A lead screw 203 is fixedly connected to the transmission end of the servo motor 202. A slider 204 is slidably connected to the side surface of the lead screw 203. An anti-detachment disc 205 is fixedly connected to the bottom of the lead screw 203. The adjustment assembly 2 also includes an L-shaped rod 206, a sealing baffle 207, a through hole 208, a conveying pipe 209, and a notch 210. An L-shaped rod 206 is fixedly connected to one side of the slider 204. A sealing baffle 207 is fixedly connected to the bottom of the L-shaped rod 206. The fixing frame 2... The interior of 01 has a through hole 208, and a conveying pipe 209 is fixedly connected inside the through hole 208. The conveying pipe 209 has a notch 210 inside. After extraction, the operator turns off the drive motor 8, opens the solenoid valve inside the conveying pipe 209, and starts the servo motor 202. The drive end of the servo motor 202 drives the lead screw 203 to rotate. The rotation of the lead screw 203 causes the slider 204 to move up and down along the lead screw 203.

The sample flow rate through the inlet of the conveying tube 209 can be controlled by adjusting the position of the sealing baffle 207, thereby precisely regulating the flow rate of the sample from the container 4 into the analyzer 14. When the sealing baffle 207 completely covers the notch 210, the sample flow is blocked; when the sealing baffle 207 partially or completely leaves the notch 210, the sample begins to flow, and the flow rate is adjusted according to the position of the sealing baffle 207. The analyzer 14 analyzes the impurities in the sample, and the analysis results are displayed in real time on the display screen 16.

The baffle 207 is compatible with the delivery pipe 209, which is L-shaped. In use, the chemical sample to be tested is poured into the container 4 through the feed pipe 7, and then an appropriate amount of extractant is added to the container 4. The extractant helps to extract impurities from the sample, which is convenient for subsequent testing. The cover plate 5 is closed, and the sealing plug 6 is ensured to fit tightly against the opening of the container 4 to prevent sample leakage. The drive motor 8 is started, and the drive end of the drive motor 8 drives the stirring shaft 9 to rotate.

At the same time, the connecting rod 11 drives the scraper 13 to move on the inner wall of the container 4 through the fixing rod 12 to prevent the sample and extractant from adhering to the cylinder wall and ensure the accuracy of the analysis.
