Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample delivery and positioning technology for sulfur analyzers, specifically to a sample delivery rod for sample delivery and positioning of sulfur analyzers. Background Technology
[0002] The sulfur content in coal is an important indicator of coal quality. The coulometric sulfur analyzer is used to determine the total sulfur content in coal. The instrument consists of a sample delivery device, a tubular furnace, a gas path, an electrolysis system, and a control system. The sample is delivered to the tubular furnace at 500℃ and 1150℃ via the sample delivery rod for decomposition. The gas enters the electrolysis system to calculate the sulfur content.
[0003] However, existing sulfur analyzers primarily use time-counting and electronic switch positioning methods, both of which struggle to accurately determine the temperature point, affecting experimental precision. Furthermore, electronic switches have a high failure rate at high temperatures. In addition, the metal sample delivery rod is prone to deformation, and the hook easily damages the quartz tray, leading to frequent malfunctions and high operating costs. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.
[0005] Therefore, one objective of this utility model is to propose a sample delivery rod for sulfur analyzer sample delivery and positioning. This sample delivery rod can be accurately positioned at a set temperature point using a temperature probe, thereby improving data accuracy. Furthermore, the sample placement platform can eliminate the need for a quartz tray, reducing costs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sample delivery rod for positioning a sulfur analyzer, comprising a sample delivery rod, one end of which is provided with a sample placement platform, and the other end is fixedly connected to a flange sleeve, the outer wall of which is fixedly connected to a support frame, the sample delivery rod having a through hole inside which a temperature probe is embedded, and the end of the temperature probe being located inside the sample placement platform.
[0007] Preferably, a connecting plate is fixedly connected to the bottom of the support frame, and a rack is provided on one side of the connecting plate. Threaded holes are provided on the adjacent sides of the rack and the connecting plate.
[0008] Preferably, a motor is provided on one side of the rack, and a gear is fixedly connected to the rotating shaft of the motor, the gear meshing with the rack.
[0009] Preferably, the sample feeding rod is made of a high-temperature resistant alloy.
[0010] Preferably, the lofting platform is equipped with a porcelain boat.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, a sample ceramic boat is placed on the sample placement platform at one end of the sample delivery rod. A temperature probe is installed inside the sample delivery rod. When the sample delivery rod moves, the temperature probe can be used to directly measure each temperature point during the operation of the sample delivery rod and accurately locate it at the set temperature point, thereby improving data accuracy. In addition, setting up a sample placement platform can eliminate the need for a quartz tray, reduce costs, and reduce failures. Attached Figure Description

[0017] Please see Figure 1 The present invention provides a sample delivery rod for positioning a sulfur analyzer, comprising: sample delivery rod 4.
[0018] Among them, such as Figures 1-3 As shown, one end of the sample feeding rod 4 is provided with a sample placement platform 6, and the other end is fixedly connected to a flange sleeve 3. A support frame 2 is fixedly connected to the outer wall of the flange sleeve 3. The sample feeding rod 4 has a through hole inside, and a temperature measuring probe 5 is embedded in the through hole. The end of the temperature measuring probe 5 is located inside the sample placement platform 6.
[0019] In use, one end of the sample delivery rod 4 is connected to the flange sleeve 3, and the other end is equipped with a sample placement platform 6. A support frame 2 is installed on the outer wall of the flange sleeve 3, and a sample ceramic boat 7 is placed on the sample placement platform 6. When the sample delivery rod 4 moves, the temperature probe 5 can be used to directly measure each temperature point of the sample delivery rod 4 during its operation.
[0020] In this embodiment, as Figure 1 and Figure 3 As shown, a connecting plate 1 is fixedly connected to the bottom of the support frame 2. A rack 10 is provided on one side of the connecting plate 1. Threaded holes 11 are provided on the adjacent sides of the rack 10 and the connecting plate 1. A motor 8 is provided on one side of the rack 10. A gear 9 is fixedly connected to the rotating shaft of the motor 8. The gear 9 meshes with the rack 10. The support frame 2 is attached to one side of the rack 10 through the bottom connecting plate 1, and the connecting plate 1 and the rack 10 are fixed by using fixing bolts passing through the threaded holes 11. The gear 9 is driven to rotate by the external motor 8, causing the rack 10 and the sample feeding rod 4 to move.
[0021] To prevent deformation of the sample feed rod 4 due to high temperature, the sample feed rod 4 is made of high temperature resistant alloy.
[0022] Based on the above technical solution, the working steps of this solution are summarized as follows: When in use, one end of the sample feeding rod 4 is connected to the flange sleeve 3, and the other end is provided with a sample placement platform 6. A support frame 2 is installed on the outer wall of the flange sleeve 3. The support frame 2 is connected to the rack 10 through the bottom connecting plate 1. The external motor 8 drives the gear 9 to rotate, so that the rack 10 and the sample feeding rod 4 can move. The sample porcelain boat 7 is placed on the sample placement platform 6.
[0023] When the sample feeding rod 4 moves, the temperature probe 5 can be used to directly measure each temperature point of the sample feeding rod 4 during its operation, and accurately locate it at the set temperature point position, thereby improving data accuracy. Placing the sample ceramic boat 7 directly on the sample placement platform 6 at one end of the sample feeding rod 4 can eliminate the need for a quartz tray, reduce costs, and reduce failures.
