Description

Technical Field

[0001] This application relates to the field of temperature measuring equipment technology, and in particular to a temperature monitoring device for an oxidation furnace. Background Technology

[0002] In related technologies, the method for monitoring key temperature points in each heating zone inside an oxidation furnace involves inserting thermocouples from the outer wall into the furnace chamber. After determining the insertion depth, the insertion hole is filled with heat-resistant materials such as asbestos rope or asbestos cloth to secure the thermocouple and prevent heat loss from the furnace. However, this method is rather cumbersome, requiring the removal and re-insertion of the heat-resistant materials such as asbestos rope or asbestos cloth when replacing or repairing thermocouples.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0025] In related technologies, the method for monitoring key temperature points in each heating zone inside an oxidation furnace involves inserting thermocouples from the outer wall into the furnace chamber. After determining the insertion depth, the insertion hole is filled with heat-resistant materials such as asbestos rope or asbestos cloth to secure the thermocouple and prevent heat loss from the furnace. However, this method is rather cumbersome, requiring the removal and re-insertion of the heat-resistant materials such as asbestos rope or asbestos cloth when replacing or repairing thermocouples.

[0026] In view of this, the purpose of this embodiment is to provide an oxidation furnace temperature monitoring device to improve the convenience of thermocouple installation and removal.

[0027] Please see Figures 1-2In this embodiment, an oxidation furnace temperature monitoring device includes an installation cylinder 20 for inserting a thermocouple 10. The inner wall of the installation cylinder 20 is provided with a limiting groove 22, the depth of which decreases from the outside to the inside. The installation cylinder 20 is provided with a clamping plate 30 that engages with the limiting groove 22. A positioning cylinder 40 is screwed into the installation cylinder 20. The positioning cylinder 40 can push the clamping plate 30 to clamp the thermocouple 10 by screwing it into the installation cylinder 20.

[0028] By adopting the technical solution of this embodiment, the rotation of the positioning cylinder 40 is used to push the clamping plates 30 together, thereby clamping and fixing the thermocouple 10, which can improve the convenience of assembling and disassembling the thermocouple 10.

[0029] It should be noted that a connecting plate 21 is welded to the end of the mounting cylinder 20. The connecting plate 21 can be bolted to the outer wall of the oxidation furnace, thereby fixing the mounting cylinder 20 on the oxidation furnace. An insertion hole is opened on the oxidation furnace that is opposite to the inner cavity of the mounting cylinder 20 for the thermocouple 10 to be inserted into the interior of the oxidation furnace.

[0030] In this embodiment, the limiting groove 22 is formed on the inner wall of the mounting cylinder 20, and the limiting groove 22 extends along the axial direction of the mounting cylinder 20. The depth of the limiting groove 22 decreases inward from the end of the mounting cylinder 20, and the two limiting grooves 22 are evenly distributed along the circumference of the mounting cylinder 20.

[0031] In this embodiment, the clamping plates 30 and the limiting grooves 22 are arranged in a one-to-one correspondence. The clamping plates 30 are constructed in an arc shape, made of heat-resistant material, and have a certain degree of elasticity. The arc of the clamping plates 30 is 180 degrees. The two clamping plates 30 form a cylinder that can enclose the thermocouple 10. A limiting plate 31 is integrally formed on the outer wall of the clamping plates 30. The limiting plate 31 and the clamping plates 30 have the same axial length, and the limiting plate 31 and the limiting grooves 22 have the same slope. The outer wall of plate 31 fits against the bottom of the limiting groove 22. The limiting plate 31 is slidably snapped into the inside of the limiting groove 22. A pull plate 32 extending out of the mounting cylinder 20 is provided at the top of the limiting plate 31. The pull plate 32 is arranged parallel to the axis of the mounting cylinder 20. The top of the pull plate 32 is bent outward by 90 degrees to form a baffle 33. The baffle 33 is used to prevent the pull plate 32 from completely retracting into the inside of the mounting cylinder 20. At the same time, it can be conveniently removed from the inside of the mounting cylinder 20.

[0032] In this embodiment, the positioning cylinder 40 is sleeved on the outside of the thermocouple 10 and can slide along the axial direction of the thermocouple 10. The positioning cylinder 40 is threadedly connected to the inner wall of the mounting cylinder 20. The positioning cylinder 40 is arranged above the clamping plate 30. When the positioning cylinder 40 is screwed into the interior of the mounting cylinder 20, it can push the clamping plate 30 to move downward. By using the snap-fit ​​cooperation between the limiting plate 31 and the limiting groove 22, the clamping plate 30 can move towards the side closer to the thermocouple 10 until the thermocouple 10 is clamped and fixed.

[0033] It should be noted that in the initial state, that is, the positioning cylinder 40 does not exert a pushing force on the clamping plate 30, and the two clamping plates 30 form a cylinder that surrounds the thermocouple 10. The outer diameter of the cylinder is equal to the inner diameter of the mounting cylinder 20, and the inner diameter of the cylinder is equal to the outer diameter of the thermocouple 10. At this time, the thermocouple 10 can slide axially relative to the cylinder in order to adjust the insertion depth.

[0034] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
