Description

Technical Field

[0001] This utility model relates to the field of shield tunnel segment manufacturing technology, and in particular to a kiln flue thermocouple protection device and a kiln flue. Background Technology

[0002] With the rapid development of the power electronics industry, higher requirements are being placed on the glass materials used in electronic product displays. Especially in the mobile terminal field, cover glass needs to possess stronger drop resistance, scratch resistance, and impact resistance. Microcrystalline glass, due to its superior strength, damage resistance, high transparency, and good corrosion resistance, has become an ideal material for cover glass in new displays. In the production process of microcrystalline glass, thermocouple protection technology in the furnace flue is crucial for ensuring product quality and production safety.

[0003] Currently, thermocouple protection technology for kiln flues mainly relies on physical isolation and chemical protection measures. Physical isolation includes using high-temperature and corrosion-resistant materials to manufacture the thermocouple housing and designing a reasonable flue structure to reduce direct contact with impurities in the flue gas. Chemical protection involves coating the thermocouple surface with an anti-corrosion coating to resist highly adhesive and corrosive substances in the flue gas. Although these technologies improve the durability and reliability of thermocouples to some extent, they still have limitations.

[0004] In the existing technology, during the production process of microcrystalline glass, due to the characteristics of its raw materials, the flue gas emitted from the kiln that fires microcrystalline glass often contains highly adhesive and highly corrosive substances. These substances often adhere to the outer shell of the flue temperature measuring thermocouple during the flue gas emission process, and even penetrate into the pipe wall into which the thermocouple is inserted, corroding the thermocouple outer shell and causing the corroded outer shell to stick tightly to the inner wall of the inserted pipe. This results in a very high frequency of flue thermocouple damage and great difficulty in replacement. Utility Model Content

[0005] The main purpose of this utility model is to propose a thermocouple protection device for kiln flue and a kiln flue, aiming to solve the technical problem in the production process of microcrystalline glass, where the flue gas emitted by the kiln often contains highly adhesive and corrosive substances that adhere to the outer shell of the temperature measuring thermocouple in the flue, corroding the outer shell of the thermocouple and causing the thermocouple shell to stick to the inner wall of the flue, making it inconvenient to disassemble and replace.

[0006] To achieve the above objectives, this utility model proposes a kiln flue thermocouple protection device. A mounting hole communicating with the flue is provided through the side wall of the flue. The kiln flue thermocouple protection device is used to protect the thermocouple. The kiln flue thermocouple protection device includes:

[0007] A connecting sleeve is installed in the mounting hole and extends away from the flue.

[0008] A movable bracket, which is mounted on the outer periphery of the connecting sleeve and extends in a direction away from the flue; and,

[0009] A fixing mechanism is connected to one end of the movable bracket away from the flue. An installation channel is formed on the fixing mechanism. The thermocouple is installed in the installation channel, and at least a portion of the thermocouple passes through the installation hole and extends into the flue.

[0010] The movable bracket can move the fixing mechanism closer to or away from the connecting sleeve, so that the thermocouple can be inserted into or extended out of the flue.

[0011] In one embodiment, the fixing mechanism includes:

[0012] A fixed sleeve, the outer periphery of which is connected to the movable bracket; and...

[0013] Thermal insulation cotton is disposed inside the fixed sleeve, and the thermocouple passes through the thermal insulation cotton.

[0014] In one embodiment, the movable support includes:

[0015] A connecting segment, wherein the connecting segment is connected to the connecting sleeve; and,

[0016] The movable segment is connected to the fixed sleeve, and the movable segment and the connecting segment are in sliding fit.

[0017] In one embodiment, the fixed sleeve has a bolt hole at one end facing the connecting sleeve, and the movable section is threadedly engaged with the corresponding bolt hole.

[0018] In one embodiment, there are multiple movable supports, which are distributed circumferentially around the outer periphery of the connecting sleeve.

[0019] In one embodiment, the outer periphery of the connecting sleeve is further provided with connecting blocks that are the same number as the movable brackets and are connected in a one-to-one correspondence.

[0020] In one embodiment, the connecting block is fastened to the corresponding movable bracket by fastening screws.

[0021] In one embodiment, the connecting sleeve is welded to the flue.

[0022] In one embodiment, the connecting sleeve is connected to the flue by screws.

[0023] Based on the same technical concept, in a second aspect, this utility model also proposes a kiln flue that applies the kiln flue thermocouple protection device described in the first aspect.

[0024] The technical solution of this utility model, by setting a connecting sleeve, a movable bracket, and a fixing mechanism, allows the connecting sleeve to be installed on the flue during use. The movable bracket and fixing mechanism allow the thermocouple to pass sequentially through the fixing mechanism, the connecting sleeve, and the mounting hole, extending into the flue. The movable bracket can move the fixing mechanism closer to or further away from the connecting sleeve, correspondingly causing the thermocouple to extend into or out of the flue. This allows the thermocouple to be installed on the side wall of the flue during use. Furthermore, because the thermocouple installation is achieved through the cooperation of the connecting sleeve, movable bracket, and fixing mechanism, the thermocouple can be easily inserted into or removed from the flue, enabling thermocouple replacement. This avoids the inconvenience of disassembly and replacement caused by the thermocouple being stuck to the side wall of the flue. Attached Figure Description

[0037] This utility model proposes a thermocouple protection device for kiln flue.

[0038] Please see Figures 1 to 5In one embodiment of this utility model, the kiln 400 flue thermocouple 600 protection device has an installation hole 500 communicating with the flue through a through-hole on the side wall of the flue. The kiln 400 flue thermocouple 600 protection device is used to protect the thermocouple 600. The kiln 400 flue thermocouple 600 protection device includes:

[0039] Connecting sleeve 100 is installed in mounting hole 500 and extends away from flue.

[0040] A movable bracket 200 is mounted on the outer periphery of the connecting sleeve 100 and extends in a direction away from the flue; and,

[0041] The fixing mechanism 300 is connected to the end of the movable bracket 200 away from the flue. An installation channel is formed on the fixing mechanism 300. The thermocouple 600 is installed in the installation channel, and at least a portion of the thermocouple 600 passes through the installation hole 500 and extends into the flue.

[0042] The movable bracket 200 can move the fixed mechanism 300 closer to or further away from the connecting sleeve 100, so that the thermocouple 600 can be inserted into or extended out of the flue.

[0043] In this embodiment, it can be further explained that the example connecting sleeve 100, the receiving bracket and the fixing mechanism 300 are all made of metal materials, and the example movable bracket 200 is preferably a hydraulic telescopic cylinder.

[0044] In this embodiment, by providing a connecting sleeve 100, a movable bracket 200, and a fixing mechanism 300, the connecting sleeve 100 is installed on the flue during use. The movable bracket 200 and the fixing mechanism 300 allow the thermocouple 600 to pass sequentially through the fixing mechanism 300, the connecting sleeve 100, and the mounting hole 500, extending into the flue. The movable bracket 200 can move the fixing mechanism 300 closer to or further away from the connecting sleeve 100, correspondingly causing the thermocouple 600 to extend into or out of the flue. This allows the thermocouple to be installed on the side wall of the flue during use. Furthermore, because the thermocouple is installed through the cooperation of the connecting sleeve, movable bracket, and fixing mechanism, the thermocouple can extend into or out of the flue during use, enabling thermocouple replacement and avoiding the inconvenience of disassembly and replacement caused by the thermocouple being stuck to the side wall of the flue.

[0045] It can be further clarified that, in this embodiment, since the thermocouple 600 can extend into or out of the flue, the surface of the thermocouple 600 can be cleaned during use, thus extending the service life of the flue. At the same time, direct contact between the thermocouple 600 and the inner wall of the flue is avoided, preventing the thermocouple 600 from sticking to the inner wall of the flue and reducing the difficulty of replacement.

[0052] The movable section 220 is connected to the fixed sleeve 310, and the movable section 220 and the connecting section 210 are in sliding fit.

[0053] In this embodiment, by using the connecting segment 210 and the movable segment 220, the present invention can achieve the function of driving the fixing mechanism 300 to move closer to or further away from the mounting hole 500 through the cooperation of the connecting segment 210 and the movable segment 220.

[0054] It should be specifically and clearly stated that the fixed sleeve 310 has a bolt hole at the end facing the connecting sleeve 100, and the movable section 220 is threadedly engaged with the corresponding bolt hole.

[0055] In this embodiment, by setting bolt holes and making the movable segment 220 correspond to the bolt holes, the present invention can connect the movable segment 220, thereby improving the connection stability.

[0056] In some alternative embodiments, there are multiple movable supports 200, which are distributed circumferentially around the outer periphery of the connecting sleeve 100.

[0057] In this embodiment, by providing multiple movable supports 200 and distributing them circumferentially around the outer periphery of the connecting sleeve 100, this invention enables the fixed support and the thermocouple 600 to move using the multiple movable supports 200. Simultaneously, the presence of multiple movable supports 200 ensures the stability of the thermocouple 600's movement.

[0058] In some preferred embodiments, the outer periphery of the connecting sleeve 100 is also provided with connecting blocks 230, which are the same number as the movable brackets 200 and are connected one-to-one.

[0059] In this embodiment, the connection block 230 is provided to improve the connection stability of the movable bracket 200 during use.

[0060] It should be specifically and clearly stated that the connecting block 230 is fastened to the corresponding movable bracket 200 by fastening screws.

[0061] In this embodiment, the corresponding movable bracket 200 is connected by the fastening screws, which improves the connection stability of the movable bracket 200.
