Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a high-temperature resistant excitation stage for a direct-reading spectrometer. Background Technology

[0002] Because the detection equipment needs to detect chloride ions in the coal gas, the chloride ions in the coal gas need to be separated. Generally, electrolysis is used to separate chloride ions. However, since chloride ions are separated from coal gas, electrolysis cannot be used because electricity would ignite the coal gas and cause an explosion. Therefore, an absorbent is used to extract chloride ions from the coal gas. However, directly using the absorbent to separate chloride ions from the coal gas is not pure enough and will carry other gases. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The terms "first," "second," "upper end," "lower end," or "one side," etc., used in this utility model to refer to numbers or ordinal numbers are for descriptive purposes only and should not be construed as explicitly or implicitly indicating relative importance or specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," "upper end," "lower end," or "one side" may explicitly or implicitly include at least one of those features.

[0026] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0027] like Figure 1-5As shown in the figure, this utility model embodiment discloses a high-temperature resistant excitation stage 1 for a direct-reading spectrometer, including a worktable 3, a fixing block 2, an excitation stage 1, a cooling system 6, a steel sample pressing device 7, a laser emitter 9, and a steel sample 10. The excitation stage 1 includes a tungsten carbide component 13 and a laser hole 12. The laser hole 12 is located in the middle of the tungsten carbide component 13, which is located at the upper end of the excitation stage 1. The fixing block 2 is located on the worktable 3, and the lower end of the excitation stage 1 is connected to the upper end of the fixing block 2. The steel sample pressing device 7 is located on the fixing block 2. One end of the cooling system 6 is connected to the spectrometer, and the other end of the cooling system 6 is connected to the interior of the excitation stage 1. One end of the laser emitter 9 is located on the worktable 3, and the other end of the laser emitter 9 passes through the steel sample pressing device 7 and the excitation stage 1, close to the upper end of the laser hole 12. The steel sample 10 is placed on the tungsten carbide component 13 to cover the laser hole 12. The steel sample pressing device 7 includes a hydraulic rod 76, the lower end of which presses against the steel sample 10.

[0028] Specifically, the worktable 3 refers to the platform on the spectrometer, which serves as a platform for assembling other components. The worktable 3 is made of metal and provides space and support for the assembled components. The fixing block 2 increases the height of the excitation stage 1 and facilitates the assembly of other components. The fixing block 2 can be made of steel or other metals through integral stamping, possessing good hardness and stability. The excitation stage 1 provides a stable placement position for the sample, ensuring that the sample does not move or shake during excitation, thereby guaranteeing the accuracy and repeatability of the excitation. The excitation stage 1 can be made by welding steel blocks according to their shape, or by stamping steel and then processing it into the required shape. The tungsten carbide component 13 is a major component on the excitation stage 1, embedded in the upper part of the excitation stage 1. The cooling system 6 is used to cool the excitation stage 1 when the high temperature generated by the laser emitter 9 causes it to heat up. One end of the cooling system 6 is located inside the excitation stage 1, and the other end is connected to the cooling device of the spectrometer. The steel sample clamping device 7 is used to hold the sample firmly on the excitation stage 1 to prevent it from shifting or moving when placed on the stage. The steel sample clamping device 7 can be electrically or hydraulically clamped. The laser emitter 9 can be a diode laser emitter 9, a fiber laser emitter 9, or a free-electron laser emitter 9. A diode laser emitter 9 is preferred due to its small size, light weight, long lifespan, simple and robust structure, wavelength range from infrared to blue light, power range from milliwatts to watts, and high photo-to-photon conversion efficiency. The steel sample 10 refers to the sample being tested.

[0029] Furthermore, the excitation stage 1 also includes a housing 101, a cooling protection tube, a groove 14, a cooling water inlet 15, and a cooling water outlet 16. The lower end of the housing 101 is connected to the upper end of the fixing pad 2. The lower end of the cooling protection tube is connected to the inner wall of the lower end of the housing 101, and the upper end of the cooling protection tube is connected to the inner wall of the upper end of the housing 101. The groove 14 is disposed at the upper end of the cooling protection tube of the housing 101. The tungsten carbide component 13 is disposed in the groove 14. The cooling water inlet 15 and the cooling water outlet 16 are disposed separately on one side of the housing 101.

[0030] Specifically, the outer shell 101 provides an assembly platform for other components and a platform for placing the steel sample 10. The outer shell 101 can be spliced ​​together by welding, or it can be stamped from steel into the required shape. The outer shell 101 can be round or square, but square is preferred because it is simple to manufacture and easy to assemble other components onto. The outer shell 101 has a round hole at both the top and bottom. The cooling protection pipe is a cylindrical tube with openings at the top and bottom. The openings of the cooling protection pipe are the same size as the round holes in the outer shell 101. It is formed by stamping from steel plate and then welding the seams to achieve a sealed state. The lower end of the cooling protection pipe is welded to the round hole at the bottom of the outer shell 101, and the upper end of the cooling protection pipe is welded to the round hole at the top of the outer shell 101. The cooling protection pipe can be integrally stamped with the outer shell 101 except for the top, which can improve the strength and sealing of both. It is better to seal the outer shell 101 with the top plate after the cooling system 6 is assembled. The groove 14 is formed during the stamping of the steel plate at the upper end of the exterior. The lower opening of the groove 14 is the same size as the opening of the cooling protection pipe, and the upper opening of the groove 14 is larger than the outer wall of the tungsten carbide component 13. Several screw holes are provided inside the lower end of the groove 14. After the tungsten carbide component 13 is fitted into the groove 14, the upper surface of the tungsten carbide component 13 is flush with the upper surface of the outer shell 101, and then it is fixed in the groove 14 by screws and screw holes. The cooling water inlet 15 and the cooling water outlet 16 are used for the installation of the cooling system 6 inside the outer shell 101.

[0031] Furthermore, the tungsten carbide component 13 includes a tungsten carbide sheet 131, a retaining ring 132, and a gasket 133. A laser hole 12 is provided in the middle of the tungsten carbide sheet 131. The lower end of the gasket 133 is connected to the upper end of the tungsten carbide sheet 131, and the upper end of the gasket 133 is connected to the lower end of the retaining ring 132.

[0032] Specifically, the tungsten carbide sheet 131 can be formed by mixing tungsten powder and carbon powder in a certain proportion and then pressing it. The tungsten carbide sheet 131 can be circular, square, or polygonal, with circular tungsten carbide sheets 131 being preferred. The tungsten carbide sheet 131 is convex in shape, with a central convex shape and a lower periphery than the convex shape. A laser hole 12 is opened in the center of the convex part of the tungsten carbide sheet 131. The tungsten carbide sheet 131 has through holes of the same size as the groove 14 near the circumference of the circumference, which facilitates the fixing of the tungsten carbide sheet 131 into the groove 14 by screws. The gasket 133 can be made of high-temperature resistant soft metal or high-temperature resistant plastic, such as polyetheretherketone, polyimide, or polybenzimidazole. It will not dissolve or be damaged at high temperatures between 260-370 degrees Celsius and has good wear resistance and corrosion resistance. The gasket 133 also has through holes similar to those on the tungsten carbide sheet 131. The retaining ring 132 is made of a single piece of metal material, such as steel, which has the properties of high temperature resistance and high hardness. The retaining ring 132 has through holes along its periphery, the same as those of the tungsten carbide sheet 131 and the washer 133. First, place one washer 133 in the groove 14 and align it with the screw hole. Then, place the tungsten carbide sheet 131 on the washer 133. Then, place another washer 133 on the tungsten carbide sheet 131. Finally, place the retaining ring 132 on the concave plane of the tungsten carbide sheet 131 so that the upper surface of the tungsten carbide sheet 131 is flush with the upper surface of the retaining ring 132. Place the tungsten carbide component 13 in the groove 14 so that the upper surface of the tungsten carbide component 13 is flush with the upper surface of the outer shell 101. Then, use a screw to pass through the screw hole and fix it to the groove 14. The upper surface of the screw is flush with the upper surface of the outer shell 101.

[0033] Furthermore, the groove 14 is provided with a threaded hole, and the tungsten carbide sheet 131, the fixing ring 132 and the washer 133 are each provided with a through hole of the same size and position as the threaded hole. The tungsten carbide sheet 131, the fixing ring 132 and the washer 133 are threadedly connected to the threaded hole in the groove 14 by screws passing through the through holes.

[0034] Specifically, the groove 14 is for embedding the tungsten carbide component 13. The shape of the groove 14 is set according to the shape of the tungsten carbide component 13. The inner wall of the groove 14 fits the outer wall of the tungsten carbide component 13. The groove 14 is integrally stamped during the stamping of the top plate of the outer shell 101. The threaded hole of the groove 14 is made by milling, tapping or turning. The threaded hole of the groove 14 is the same size and position as the through hole of the tungsten carbide sheet 131, the retaining ring 132 and the washer 133, so that the tungsten carbide component 13 can be tightened and fixed with screws.

[0035] Furthermore, the cooling system 6 includes an inner cooling pipe 61, an inlet pipe connector 62, an outlet pipe connector 63, a cooling inlet pipe 64, and a cooling outlet pipe 65. One end of the inlet pipe connector 62 is connected to the cooling water inlet 15, and the other end of the inlet pipe connector 62 is connected to one end of the cooling inlet pipe 64. One end of the outlet pipe connector 63 is connected to the cooling water outlet 16, and the other end of the outlet pipe connector 63 is connected to one end of the cooling outlet pipe 65. The inner cooling pipe 61 is disposed inside the outer casing 101. One end of the inner cooling pipe 61 is connected to one end of the inlet pipe connector 62, and the other end of the inner cooling pipe 61 is connected to one end of the outlet pipe connector 63. The other ends of the cooling inlet pipe 64 and the cooling outlet pipe 65 are respectively connected to the spectrometer.

[0036] Furthermore, the inner cooling tube 61 is wound several times around the outer edge of the cooling protection tube. One end of the inner cooling tube 61 is connected to one end of the water inlet pipe connector 62. Then, it is wound several times from the outside to the inside along the lower end of the outer shell 101 outside the cooling protection tube. The inner cooling tube 61 is then wound around the outer edge of the cooling protection tube to the upper end of the outer shell 101. Finally, the inner cooling tube 61 is wound several times along the upper end of the outer shell 101. The other end of the inner cooling tube 61 is finally connected to one end of the water outlet pipe connector 63. When the high temperature is generated during the operation of the excitation transmitter, the inner cooling tube 61 cools down the excitation platform 1.

[0037] Furthermore, the fixing pad 2 is also provided with fixing holes 21, laser pad holes 22 and support holes 23. Several fixing holes 21 are provided, and the fixing holes 21 are respectively located on the periphery of the fixing pad 2. The laser pad holes 22 are located on the fixing pad 2 symmetrically with the laser holes 12. The support holes 23 are located on one side of the fixing pad 2. The fixing pad 2 is connected to the worktable 3 by screws passing through several fixing holes 21.

[0038] Furthermore, the steel sample clamping device 7 includes a support rod 71, a support block 72, a crossbar 73, a hydraulic pipe 74, a hydraulic column 75, and a hydraulic rod 76. The support rod 71 is hollow inside, and each of the upper and lower ends of the hollow section inside the support rod 71 has a through hole. The upper end of the hydraulic column 75 is closed, and the interior of the hydraulic column 75 is hollow from the upper end to the lower end. The upper end of the hydraulic column 75 has a through hole communicating with the interior. One end of the hydraulic pipe 74 is connected to the through hole on the upper end of the support rod 71. The other end of pipe 74 is connected to a through hole on one side of the upper end of hydraulic column 75. The through hole on one side of the lower end of support rod 71 is connected to the spectrometer through hydraulic pipe 74. The lower end of support rod 71 is movably connected to the support hole 23 on fixed pad 2. Support block 72 is set near the upper end of support rod 71. One side of support block 72 is connected to one end of crossbar 73. The lower end of hydraulic column 75 passes through the other end near crossbar 73. One end of hydraulic rod 76 is connected to the inside of hydraulic column 75. The other end of hydraulic rod 76 presses against steel sample 10. When hydraulic column 75 rotates onto steel sample 10, the sulfur analyzer delivers pressure in the start state, causing hydraulic rod 76 to move downwards and press against steel sample 10 without moving. After the test is completed, sulfur analyzer releases pressure, causing hydraulic rod 76 to retract upwards and move away from above steel sample 10, so that steel sample pressing device 7 can be rotated to one side.

[0039] Furthermore, the high-temperature excitation stage 1 also includes a side wing fixing block 5 and a padding block 11. The side wing fixing block 5 is L-shaped. One side of the side wing fixing block 5 is connected to the front side of the outer shell 101, and the other side of the side wing fixing block 5 is connected to the upper end of the padding block 11. The lower end of the padding block 11 is connected to the upper end of the fixing pad 2. The other side of the side wing fixing block 5 is threaded to the fixing pad 2 by a screw passing through the padding block 11.

[0040] Specifically, the side wing fixing block 5 is L-shaped. One end is fixed to the outer shell 101 with screws, and the other end is connected to the upper screw of the fixing pad 2 through the shim block 11. The side wing fixing block 5 can be made of metal, such as steel, which is integrally stamped to improve its robustness. The shim block 11 can be cylindrical or square, providing friction between the side wing fixing block 5 and the fixing pad 2, and also reducing the vibration of the excitation table 1 to prevent the screw from loosening.

[0041] Furthermore, the excitation stage 1 is also provided with a positioning and fixing block 8, which is located on the other side of the upper end of the outer shell 101. The other end of the positioning and fixing block 8 is provided with a positioning hole, which is fitted onto the positioning rod 4 for positioning.

[0042] Specifically, the positioning and fixing block 8 can be semi-circular, square, or polygonal, and can be made of metal, such as steel stamping. It is welded to the other side of the upper end of the outer shell 101. Alternatively, the positioning and fixing block 8 can be integrally stamped with the top plate of the outer shell 101 during the stamping process. The positioning rod 4 is fixed to one side of the sulfur analyzer worktable 3 and is mainly used for positioning the excitation platform 1. After positioning, the excitation platform 1 is fixed with screws.

[0043] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
