[0002] During the glass production process, raw materials are melted in a glass furnace to form molten glass. To ensure the quality of the molten glass, it is necessary to monitor the real-time temperature of the molten glass to prevent quality problems in the produced glass. For example, the temperature of the glass can be accurately measured by inserting a thermocouple into the molten glass. A through hole is provided on the bottom wall of the furnace, and a thermocouple with a platinum sleeve is inserted upward from the bottom of the furnace through the through hole into the molten glass. A seal is formed between the platinum sleeve and the through hole to prevent leakage of the molten glass. The thermocouple is mainly supported by the bottom wall of the furnace. There is a fixed bracket for the thermocouple in the prior art, with application number 201720253664.8 and authorization announcement date 20171024. This patent sets a first bracket and a second bracket, and through the cooperation of the first bracket and the second bracket, the position of the thermocouple is adjusted to ensure the stability of the thermocouple.

[0003] However, when the temperature of the glass liquid fluctuates, the bottom wall of the furnace also expands or contracts accordingly, causing the position of the thermocouple to shift, affecting the measurement accuracy. Thermocouple temperature sensors are consumable parts. In order to avoid affecting the accuracy error, they generally need to be adjusted or replaced at regular intervals.

[0004] Therefore, the prior art lacks a thermocouple assembly with good stability. Utility Model Content

[0013] In some embodiments, the thermocouple assembly further includes an anti-slip washer, the fastener includes a stud and a nut, nuts are provided at both ends of the support member, and the anti-slip washer is provided between the support member and the nut.

[0014] In some embodiments, a first through hole is provided in the middle of the support member, the thermocouple passes through the first through hole, and the thermocouple is spaced apart from the support member.

[0015] In some implementations, the thermocouple assembly further includes an insulating block having an insulating hole formed therein, the insulating block being disposed on the support member, and the thermocouple passing through the insulating hole.

[0016] In some embodiments, the thermocouple assembly further includes a second fastener that secures the thermocouple to the insulating member.

[0017] In some embodiments, the support member is plate-shaped; or,

[0018] The middle and side parts of the support member are transitioned into arcs.

[0019] In order to solve the above technical problems, the utility model also provides a glass kiln, which includes the above thermocouple assembly.

[0020] Through the above-mentioned technical solution, the thermocouple assembly provided by the present invention utilizes a high-temperature-resistant alloy material, maintaining structural stability at temperatures exceeding 1200°C.

[0033] This embodiment provides a thermocouple assembly 1 for use in a glass furnace 8, such as Figure 1 As shown, the thermocouple assembly 1 includes a support 2 and a thermocouple 6. Both ends of the support 2 are fixedly connected to the steel beam 7 of the glass furnace. The thermocouple 6 passes through the support 2 and is fixed relative to the support 2. The support 2 is made of a high-temperature resistant alloy material and can withstand temperatures of 1200°C-1600°C, which solves the problem of poor stability of the traditional thermocouple assembly 1 in high-temperature environments.

[0034] Among them, the thermocouple assembly 1 uses a high-temperature resistant alloy material, which has excellent oxidation resistance and thermal stability, and can maintain structural stability within a temperature range of 1200°C-1600°C, ensuring that the thermocouple 6 maintains measurement accuracy and reliability under extreme working conditions.

[0035] In some embodiments, the high-temperature resistant alloy includes a molybdenum alloy or a chromium-molybdenum alloy, or contains both of the above alloys. The molybdenum alloy is a non-ferrous alloy composed of molybdenum as a matrix and other elements added. The molybdenum alloy has good thermal conductivity, electrical conductivity and low expansion coefficient, and has high strength at high temperatures (1200-1750°C).

[0036] In some embodiments, as Figure 1As shown, the thermocouple assembly 1 further includes a fastener 3. The support member 2 is provided with a mounting hole 22. The fastener 3 passes through the mounting hole 22 to fix the support member 2 to the steel beam 7. The fastener 3 is detachable, which facilitates debugging and installation between the fastener 3 and the support member 2. The fastener 3 is fixedly connected to the steel beam 7. The fastener 3 can be welded to the steel beam 7 or fixed to the steel beam 7 by other fixing methods.

[0037] In some embodiments, as Figure 2 As shown, the support member 2 is in a plate shape. The plate-shaped support member 2 increases the heat dissipation area, facilitates heat exchange with the outside, and improves the heat exchange efficiency of the support member 2.

[0038] The arc transition between the middle portion 21 and the side portions of the support member 2 prevents stress concentration in the middle portion 21 of the support member 2, which may cause local damage to the support member 2.

[0039] In some embodiments, as Figure 2 As shown, both ends of the support member 2 are rectangular, and the extending direction of the mounting hole 22 is parallel to the length direction of the rectangle.

[0040] In some embodiments, as Figure 2 As shown, the mounting hole 22 is strip-shaped, and mounting holes 23 are symmetrically provided at both ends of the support member 2. The mounting hole 22 is provided with multiple mounting positions, and the fastener 3 can be switched between different mounting positions, which facilitates the debugging of the fastener 3 during the process of fixing the support member 2, and is used to firmly fix the support member 2 to the bottom of the glass furnace.

[0041] In some embodiments, as Figure 1 As shown, the thermocouple assembly 1 also includes an anti-slip gasket 31, the fastener 3 includes a stud 32 and a nut 33, and nuts 33 are provided at both ends of the support member 2. The anti-slip gasket 31 is provided between the support member 2 and the nut 33 to prevent the support member 2 from slipping or loosening due to thermal expansion or other factors under high temperature conditions.

[0042] In some embodiments, as Figure 2 As shown, a first through hole 211 is provided in the middle portion 21 of the support member 2 , and the thermocouple 6 passes through the first through hole 211 , and the thermocouple 6 is spaced apart from the support member 2 .

[0043] In some implementations, such as Figure 1 As shown, the thermocouple assembly 1 further includes an insulating block 4 having an insulating hole 41. The insulating block 4 is disposed on the support 2, and the thermocouple 6 passes through the insulating hole 41 to ensure insulation between the thermocouple 6 and the support 2. The insulating block 4 can effectively isolate the thermocouple 6 from the direct effects of current and voltage, while also protecting the electrical equipment of the glass furnace.

[0044] In some embodiments, as Figure 1As shown, the thermocouple assembly 1 also includes a second fastener 5, which fixes the thermocouple 6 on the insulating member. The second fastener 5 is adjustable and can be used to install thermocouples 6 with different aperture sizes. The second fastener 5 is made of elastic material, so that the thermocouple 6 can be tightly fixed on the insulating block 4 to avoid displacement due to vibration or thermal expansion.

[0045] This embodiment also provides a glass furnace 8, such as Figure 1 As shown, the glass furnace includes a thermocouple assembly 1 as in any of the above embodiments. The thermocouple assembly 1 is installed below the brick 9 of the glass furnace 8. The thermocouple 6 passes through the gap between the brick 9 and is partially arranged above the brick 9 to detect the temperature during the glass melting process. In order to prevent the glass liquid from flowing out from the gap between the thermocouple 6 and the brick 9, compressed air is used to cool the gap between the thermocouple 6 and the brick 9 to solidify the glass liquid in the gap, while also preventing the thermocouple assembly 1 from deformation. The problem of poor stability of traditional brackets in high temperature environments is solved. The thermocouple assembly 1 in this embodiment has excellent heat dissipation effect and thermocouple protection ability, and can ensure the measurement accuracy and reliability of the thermocouple under extreme working conditions. Specific actual use shows that the thermocouple is not directly corroded by high temperature and molten glass in actual applications, and the stability and accuracy of the temperature measurement data have been significantly improved.

[0046] When used specifically, Figure 1 、 Figure 2 As shown, compressed air is used to cool the holes of the thermocouple 6. While the thermocouple 6 is cooling, deformation and aging of the bracket are avoided. The thermocouple assembly 1 is equipped with a heat shielding protection device, which can be insulated with thermal insulation cotton and thermal insulation fiber cloth. The heat shielding device is wrapped around the outside of the thermocouple 6 to isolate the direct impact of high temperature on the thermocouple 6. In actual application, the thermocouple 6 is not directly corroded by high temperature and molten glass. The stability and accuracy of the temperature measurement data are significantly improved. The insulating block 4 effectively extends the service life of the thermocouple 6 and reduces the failure rate caused by high temperature environment.
