Description

Technical Field

[0002] Atomic absorption spectrophotometers, as core equipment for trace element analysis, are widely used in chemical detection, environmental monitoring, metallurgical industry, and other fields. Their detection accuracy depends on the accuracy of sample collection and the cleanliness of the equipment's sample introduction system. Therefore, the supporting sample collection device must simultaneously meet the requirements of automated sample supply, efficient cleaning and maintenance, and precise sampling control.

[0003] In traditional atomic absorption spectroscopy detection, sample collection and equipment cleaning mainly rely on manual operation. For batch detection scenarios, frequent opening and closing of equipment and adjustment of vessel positions can easily lead to operator fatigue. Traditional devices are usually equipped with a single cleaning solution container or rely on manual replacement of the cleaning solution. Reusing a single cleaning solution can easily lead to cross-contamination due to impurities, affecting the accuracy of the detection results. Therefore, there is still room for improvement in the aforementioned existing technologies. Summary of the Invention

[0014] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0015] This application discloses a collection device based on atomic absorption spectrophotometer detection, including a placement box 1, on which a photometer is placed. The interior of the placement box 1 is provided with a partition 2, which divides the interior space of the placement box 1 into a cleaning chamber and a placement chamber. Both the partition 2 and the placement box 1 are provided with through holes. A cleaning mechanism 3 is provided in the cleaning chamber, and a placement mechanism 4 is provided in the placement chamber. A collection mechanism 5 connected to the water pipe of the photometer is provided at the upper end of the placement box 1. The left end of the placement box 1 is an open structure and is provided with a closing door through a hinge. When a container containing a sample needs to be placed, the closing door is opened and the container is placed into the placement mechanism 4.

[0016] By adopting the above technical solution, the sample container to be tested is placed into the placement mechanism 4 during the operation. The placement mechanism 4 controls the orderly movement of the sample to be tested and the position of the sample in conjunction with the insertion hole. During the operation, the collection mechanism 5 first works with the cleaning mechanism 3 to clean the photometer before testing. Then, it passes through the insertion hole on the placement box 1 and the partition 2 to extract the sample from the container in the placement mechanism 4 for automated collection and testing.

[0017] The placement mechanism 4 includes an electric slider 41 disposed on the inner wall of the lower end of the placement box 1. The electric slider 41 has a circular structure. A driven frame 42 is evenly disposed along the circumference of the electric slider 41. A positioning element 43 is disposed on the driven frame 42. A positioning frame 44 is disposed on the positioning element 43. A clamping element 45 is disposed inside the positioning frame 44. A guide block 46 is disposed inside the placement box 1. The positioning element 43 is connected to the guide block 46.

[0018] The positioning component 43 includes a positioning frame 431 slidably mounted on the driven frame 42. The driven frame 42 has a circular hole. The positioning frame 431 is provided with a positioning rod 432. The positioning rod 432 slides through the circular hole and fits against the guide block 46. A spring is sleeved on the positioning rod 432 located between the driven frame 42 and the positioning frame 431. The positioning frame 44 is mounted on the positioning frame 431. The guide block 46 has a cam structure and a guide groove is provided on the guide block 46. The end of the positioning rod 432 away from the positioning frame 431 is slidably mounted in the guide groove.

[0019] By adopting the above technical solution, the positioning rod 432 drives the positioning frame 44 to adjust its position on the driven frame 42 as the contact position with the guide block 46 changes during operation. When the positioning rod 432 moves to the protruding position of the guide block 46, the positioning frame 44 moves to a suitable position toward the opening of the placement box 1, so that the staff can easily place the container containing the sample into the positioning frame 44.

[0020] The clamping member 45 includes clamping holes evenly arranged around the circumference of the positioning frame 44, a clamping rod 451 slidably arranged in the clamping holes, an auxiliary clip 452 provided on the clamping rod 451, and a spring provided between the clamping rod 451 and the outer wall of the positioning frame 44.

[0021] By adopting the above technical solution, in continuous testing operations, the container containing the test sample is placed into the positioning frame 44, and the container in the positioning frame 44 is limited by the clamping member 45 to ensure that the sampling mechanism 5 can accurately sample and extract the sample from the container during operation. During operation, the driven frame 42 is controlled by the electric slider 41 to rotate in the placement box 1. During this process, the contact position between the positioning member 43 and the guide block 46 on the driven frame changes. When the positioning frame 42 moves to the opening position of the placement box 1, at this time... The guide block 46 protrudes towards the opening direction at the contact point with the positioning member 43. The positioning frame 44 is moved towards the opening direction of the placement box 1 to a suitable position through the cooperation between the positioning member 43 and the guide block 46. In this state, the container containing the sample is placed into the positioning frame 44. Through the continuous movement of the electric slider 41, the container containing samples of different specifications is placed into the positioning frame 44 and positioned by the clamping member 45. Through this technical solution, the automatic feeding of samples for sampling and testing can be automatically completed during operation.

[0022] The cleaning mechanism 3 includes a motor mounted on a partition 2. A rotating plate 31 is mounted on the output shaft of the motor. Connecting rods 32 are evenly arranged along the circumference of the rotating plate 31. A placement rack 33 is mounted on the connecting rods 32. The lower end of the placement rack 33 is slidably connected to the placement box 1. A water bottle is placed inside the placement rack 33.

[0023] By adopting the above technical solution, the calibrator needs to be purified when testing samples of different specifications. During the operation, the cleaning solution used to purify the calibrator is placed in multiple water bottles, which enables continuous cleaning during the sampling and testing process. The rotating plate 31 is controlled by a motor to rotate. During the rotation, the rotating plate 31 drives the water bottles on the placement rack 33 to move to the working position in turn via the connecting rod 32. This ensures the purity of the cleaning solution during the purification of the calibrator, thereby ensuring that the cleaning solution can effectively clean the calibrator. By rotating different cleaning solutions, the contamination caused by the repeated use of a single cleaning solution is avoided, ensuring efficient cleaning of the photometer pipeline and improving the detection accuracy.

[0024] The collection mechanism 5 includes an electric push rod 51 mounted on the placement box 1. A linkage frame 52 is mounted on the electric push rod 51. A suction tube 53 and a guide sleeve 54 are mounted on the linkage frame 52. The water pipe on the scale meter passes through the guide sleeve 54 and is connected to the suction tube 53.

[0025] Using the above technical solution, the height of the suction tube 53 on the linkage frame 52 is adjusted by controlling the electric push rod 51 during operation. It can extract the purification liquid in the cleaning bottle or the medicine in the container in the positioning frame 44 according to the work needs. The sampling and testing process requires less human intervention and can avoid the problem of large error in the test data due to operational errors.

[0026] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
