Description

Technical Field

[0001] This utility model relates to the field of analytical instrument technology, specifically to a continuous sample injection mechanism for an infrared sulfur analyzer. Background Technology

[0002] The continuous sample feeding mechanism for infrared sulfur analyzers is a core auxiliary component of the instrument. Its core function is to achieve automated and continuous sample delivery, working in conjunction with the infrared detection system to complete efficient and accurate sulfur content analysis. It is widely used in sulfur content detection scenarios in energy, metallurgy, chemical, and environmental protection fields. It can load multiple samples at once and automatically complete the cycle of positioning, sample delivery, testing, and sample disposal.

[0003] Existing sample feeding mechanisms typically use a sample feed rod to grab the test tube or crucible containing the sample. The clamping device of the sample feed rod (such as a claw or elastic clip) is prone to wear and deformation after long-term use, which can lead to a decrease in the fixing force on the sample bottle and cause it to fall off during transportation. Therefore, a continuous sample feeding mechanism for an infrared sulfur analyzer is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a continuous sample injection mechanism for an infrared sulfur analyzer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A continuous sample injection mechanism for an infrared sulfur analyzer includes an infrared sulfur analyzer body and an operating platform. The operating platform is fixedly connected to the bottom end of the infrared sulfur analyzer body, and a support leg is fixedly connected to the bottom end of the operating platform. A first motor is installed inside the operating platform, and a turntable is fixedly connected to the output end of the first motor. The top end of the turntable has a mounting groove, and a support ring located inside the operating platform is fixedly connected to the bottom end of the turntable, with the support ring and the operating platform rotatably connected. A rotatable ball bearing is embedded in the bottom end of the support ring. A second motor is fixedly connected to the bottom end of the operating platform, and a rotatable electric telescopic rod located inside the operating platform is fixedly connected to the output end of the second motor. A support leg is fixedly connected to the outer side of the electric telescopic rod. The worktable has a rotatable limiting ring inside. The mounting groove has a mounting seat inside. The bottom end of the mounting seat has a first limiting groove. The mounting seat has a guide groove above the first limiting groove inside. The mounting seat has a second limiting groove above the guide groove inside. The top end of the electric telescopic rod is fixedly connected to a support rod located inside the first limiting groove and the guide groove. The top end of the support rod is fixedly connected to a limiting plate located inside the second limiting groove. The top end of the limiting plate is fixedly connected to a magnet layer located inside the second limiting groove, and the magnet layer is magnetically connected to the mounting seat. The outside of the mounting seat is fixedly connected to a limiting strip located inside the mounting groove. The top end of the mounting seat is fixedly connected to a sample tube holder.

[0006] Preferably, the inner shape of the mounting groove matches the outer shape of the mounting base, and the inner side of the mounting groove and the outer side of the mounting base fit together.

[0007] Preferably, the number of balls is several, and the balls are evenly arranged in a spaced manner inside the support ring with the center of the turntable as the center.

[0008] Preferably, the mounting slot, mounting base, and sample tube holder are a group, and there are several groups in total. The mounting slot, mounting base, and sample tube holder are evenly arranged inside the turntable with the center of the turntable as the center.

[0009] Preferably, there are four support legs, which are arranged symmetrically at the corners of the bottom of the operating table.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the electric telescopic rod, mounting groove, mounting base, support rod and limiting plate and other components can be set to drive the sample to be tested into the infrared sulfur analyzer body in a smooth manner by pushing it out. No matter how long it is used, the problem of decreased fixation effect can be avoided. It effectively avoids falling off due to insufficient clamping force during the transportation process. This solves the problem that the existing sample feeding mechanism generally uses the sample feeding rod to grab the test tube or crucible containing the sample. The clamping device of the sample feeding rod (such as claws, elastic clips) is prone to wear and deformation after long-term use, which will lead to a decrease in the fixing force on the sample bottle and easy falling off during the transportation process. 2. In this utility model, by setting components such as a limiting plate, a magnet layer, a second motor, a first limiting groove, a guide groove, and a second limiting groove, the mounting base and the limiting plate can be locked together, further enhancing the stability during transportation and preventing the sample tube from falling and affecting the testing.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A continuous sample injection mechanism for an infrared sulfur analyzer includes an infrared sulfur analyzer body 1 and an operating platform 2. The operating platform 2 is fixedly connected to the bottom end of the infrared sulfur analyzer body 1, and a support leg 3 is fixedly connected to the bottom end of the operating platform 2. A first motor 4 is installed inside the operating platform 2, and a turntable 5 is fixedly connected to the output end of the first motor 4. A mounting groove 6 is opened at the top of the turntable 5, and a support ring 7 located inside the operating platform 2 is fixedly connected to the bottom end of the turntable 5, and the support ring 7 and the operating platform 2 are rotatably connected. A rotatable ball bearing 8 is embedded in the bottom end of the support ring 7. A second motor 9 is fixedly connected to the bottom end of the operating platform 2, and a rotatable electric telescopic rod 10 located inside the operating platform 2 is fixedly connected to the output end of the second motor 9. A rotatable limiting ring 11 located inside the operating platform 2 is fixedly connected to the outer side of the electric telescopic rod 10. The mounting slot 6 is equipped with a mounting base 12. The bottom of the mounting base 12 is provided with a first limiting slot 13. The mounting base 12 is provided with a guide slot 14 located above the first limiting slot 13. The mounting base 12 is provided with a second limiting slot 15 located above the guide slot 14. The top of the electric telescopic rod 10 is fixedly connected to a support rod 16 located inside the first limiting slot 13 and the guide slot 14. The top of the support rod 16 is fixedly connected to a limiting plate 17 located inside the second limiting slot 15. The top of the limiting plate 17 is fixedly connected to a magnet layer 18 located inside the second limiting slot 15, and the magnet layer 18 is magnetically connected to the mounting base 12. The outer side of the mounting base 12 is fixedly connected to a limiting strip 19 located inside the mounting slot 6. The top of the mounting base 12 is fixedly connected to a sample tube holder 20.

[0017] The inner shape of the mounting groove 6 matches the outer shape of the mounting base 12. The inner side of the mounting groove 6 and the outer side of the mounting base 12 fit together, which can drive the sample tube holder 20 to move more smoothly. There are several balls 8, which are evenly arranged in a spaced pattern inside the support ring 7 with the center of the turntable 5 as the center. This can further reduce the resistance when the turntable 5 rotates and improve the support effect. The mounting groove 6, the mounting base 12 and the sample tube holder 20 are a group, and there are several groups. The mounting groove 6, the mounting base 12 and the sample tube holder 20 are evenly arranged inside the turntable 5 with the center of the turntable 5 as the center, so as to support multiple groups of sample detection at the same time. There are four support legs 3, which are symmetrically arranged at the corners of the bottom of the operating table 2.

[0018] Workflow: When using an infrared sulfur analyzer with a sample introduction mechanism, the entire system is powered externally and controlled and driven by an existing infrared sulfur analyzer. First, all sample tubes are sequentially placed into the sample tube holder 20. The output of the first motor 4, controlled by the infrared sulfur analyzer body 1, drives the turntable 5 to rotate. The support ring 7 and ball bearings 8 provide support for the turntable 5 while reducing frictional resistance. The first motor 4 rotates a predetermined number of revolutions according to the instructions from the infrared sulfur analyzer body 1, causing the turntable 5 to rotate... The mounting slot 6 and mounting base 12 are moved sequentially above the electric telescopic rod 10. When the mounting base 12 reaches the designated position, the first motor 4 stops rotating, and the infrared sulfur analyzer body 1 starts the electric telescopic rod 10, causing the electric telescopic rod 10 to drive the support rod 16, the limiting plate 17, and the magnet layer 18 to move upward, so that the limiting plate 17 and the magnet layer 18 pass through the first limiting slot 13 and enter the guide slot 14. When the top of the magnet layer 18 and the guide slot 14 are completely in contact, the electric telescopic rod 10 stops rising. The current rising height is the system's... After setting a pre-defined rising height, the infrared sulfur analyzer body 1 will activate the second motor 9. The output of the second motor 9 will drive the electric telescopic rod 10, support rod 16, limiting plate 17, and magnet layer 18 to rotate under the guidance of the limiting ring 11 and guide groove 14. This will cause the limiting plate 17 to rotate 90 degrees. Once 90 degrees is reached, the second motor 9 will stop rotating, and the electric telescopic rod 10 will be activated again, causing the limiting plate 17 to continue moving upwards into the second limiting groove 15. Simultaneously, it will push the mounting base 12, sample tube holder 20, and sample... according to the set height. The sample tube rises into the infrared sulfur analyzer body 1 for testing. The first limiting groove 13, guide groove 14 and second limiting groove 15, together with the limiting plate 17 and magnet layer 18, can effectively prevent the mounting base 12 from falling off midway and ensure its stable operation. After the test is completed, the same logic is used to reverse the above operation so that the mounting base 12 returns to the mounting groove 6. The electric telescopic rod 10 will also be reset. The turntable 5 drives the next set of mounting bases 12 and sample tube seats 20 to move directly above the electric telescopic rod 10 for the next test.
