Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to an automatic sampler for a cold atom absorption differential mercury analyzer. Background Technology

[0002] Cold atomic absorption differential mercury analyzers are trace mercury detection devices based on cold atomic absorption spectrometry. They are widely used for the precise analysis of mercury content in environmental monitoring (such as water, soil, and atmospheric particulate matter), food hygiene (such as seafood and grains), industrial production (such as wastewater and exhaust gas), and scientific research. Their core performance depends not only on the accuracy of core components such as the optical system and atomizer, but also closely on the stability and automation level of the sample pretreatment and injection processes.

[0003] Traditional manual sample introduction requires manual completion of steps such as pipetting, injection, and washing, with a single injection typically taking 30 seconds to 2 minutes and not allowing for parallel operations. For scenarios requiring batch testing (such as dozens to hundreds of samples per day), such as environmental monitoring and food safety sampling, manual sample introduction significantly prolongs the overall testing cycle, leading to delayed data feedback. Traditional manual sample introduction methods suffer from low efficiency, large human error, and insufficient standardization, making it difficult to meet the demands of modern testing scenarios for high precision, high throughput, and high reliability. Therefore, it is necessary to develop an automatic sampler for cold atom absorption differential mercury analyzers. Its core objective is to address the aforementioned pain points and promote the intelligent and standardized upgrading of mercury measurement technology. Utility Model Content

[0026] A vertical rod 6 is fixedly connected to the top of the base 1, and a second rotating assembly is fixedly connected to the top of the vertical rod 6. By setting the second rotating assembly, the aspiration assembly is driven to rotate, which facilitates the detection of reagents in the syringe 12, reduces errors, and cleans the syringe 12. The second rotating assembly includes a second motor 7, which drives the horizontal rod 8 to rotate, causing the aspiration assembly to turn towards the placement platform 5, so that the syringe 12 is located at the top of the test tube. The output shaft of the second motor 7 is fixedly connected to the horizontal rod 8, and a hydraulic rod 9 is fixedly connected inside the horizontal rod 8. The hydraulic rod 9 drives the mounting plate 10 to move, so that the syringe 12 moves to the top of the mercury analyzer. One end of the hydraulic rod 9 is fixedly connected to the mounting plate 10, and a cylinder 11 is fixedly connected to the top of the mounting plate 10. The cylinder 11 drives the syringe 12 to move downward, and the telescopic shaft of the cylinder 11 is fixedly connected to the aspiration assembly.

[0027] A support column 2 is fixedly connected to the bottom of the base 1. The first rotating assembly includes a first motor 3, which drives the workbench 4 to rotate and the placement platform 5 to rotate, thus detecting the reagent in the next test tube. The output shaft of the first motor 3 is fixedly connected to the workbench 4. The top of the workbench 4 is equipped with a placement platform 5, which has a placement slot 501 inside. The placement slot 501 contains the test tube containing the reagent to be tested. The aspiration assembly includes a syringe 12, with an electric push rod 13 fixedly connected to the top of the syringe 12. The electric push rod 13 drives the piston 14 to move downward inside the syringe 12, so that the piston 14 is located at the bottom of the syringe 12. When the injection port... When the syringe 12 comes into contact with the reagent, the electric push rod 13 drives the piston 14 to move back, creating pressure inside the syringe 12, so that the syringe 12 is filled with reagent. One end of the electric push rod 13 is fixedly connected to the piston 14. The bottom of the syringe 12 is fixedly connected to the injection port 15. During testing, the injection port 15 comes into contact with the reagent in the test tube. During cleaning, the injection port 15 comes into contact with the cleaning agent in the cleaning tank 17.

[0028] Working principle: In use, the mercury analyzer is installed at the top of the base 1, and the test tube to be tested is placed in the placement slot 501 in the placement platform 5. The second motor 7 drives the crossbar 8 to rotate, causing the aspiration assembly to turn towards the placement platform 5, so that the syringe 12 is at the top of the test tube. The cylinder 11 drives the syringe 12 to move down, and the electric push rod 13 drives the piston 14 to move down inside the syringe 12, so that the piston 14 is at the bottom of the syringe 12. When the syringe 12 is moved down into the test tube and the injection port 15 contacts the reagent in the test tube, the electric push rod 13 drives the piston 14 to move back, creating pressure inside the syringe 12, so that the syringe 12 is filled with reagent. The telescopic shaft of the cylinder 11 drives the syringe 12 to move back, and the second motor... Motor 7 drives the crossbar 8 to rotate, moving the syringe 12 to the mercury analyzer. Then, the syringe 12 moves downward, and the electric push rod 13 drives the piston 14 to move downward inside the syringe 12, dripping the reagent onto the mercury analyzer. The mercury analyzer detects the reagent. The second motor 7 drives the crossbar 8 to rotate, positioning the syringe 12 at the top of the cleaning tank 17. The cylinder 11 moves the syringe 12 downward, positioning it inside the cleaning tank 17 to clean the residual reagent inside the syringe 12. The first motor 3 is then activated, driving the worktable 4 to rotate, which in turn drives the placement platform 5 to rotate, allowing the reagent in the next test tube to be detected. Through the coordinated use of the first motor 3, the second motor 7, and the cylinder 11, rapid reagent detection can be achieved.
