Description

Technical Field

[0001] The utility model relates to the field of heat treatment, in particular to a thermocouple heat insulation device. Background Art

[0002] In modern industry, precise temperature measurement and control are key factors in ensuring stable production processes and high-quality products. Especially in high-temperature environments, the accuracy and reliability of temperature measurement are directly related to the safe operation of equipment and the final quality of the product. However, existing temperature measurement technologies, particularly those based on thermocouples, face several challenges in practical applications.

[0003] In today's existing technology, thermocouples in high-temperature environments need to have good thermal insulation properties to prevent the heat from the heater from being directly transferred to the measuring element, affecting its measurement accuracy. However, excessive thermal insulation may prevent the heat generated by the thermocouple itself from being effectively dissipated, which in turn causes temperature drift or measurement errors. The greater the load on the heater, the greater the error, and the processing results are often unsatisfactory. Moreover, in harsh environments such as high temperature and corrosion, thermocouples are extremely susceptible to damage or performance degradation, resulting in inaccurate or invalid measurement data. Traditional thermocouple installation systems are often more complex in structure, and the installation and removal process is cumbersome. Utility Model Content

[0014] Figure 2 This is a schematic diagram of the housing of the thermocouple insulation device according to Example 2 of the present utility model; DETAILED DESCRIPTION

[0015] Hereinafter, the thermocouple insulation device of the present invention will be described in detail with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 The thermocouple thermal insulation device shown includes a shell, a supporting partition, a thermal insulation layer, a thermocouple, and a fixing plate.

[0017] The housing 10 is a hollow cuboid. A circular hole 11 is provided on the right side of the housing 10 . The circular hole 11 is located at an upper position and forms a gap with the housing 10 .

[0018] Preferably, the shell 10 is a hollow cuboid with a length of 80 to 100 mm, a width of 12 to 15 mm, and a height of 3 to 7 mm. The compact structure can reduce the conduction and radiation of heat, and is more convenient during the installation process. Four fixing plates 40 are installed on the top of the shell to fix the shell 10 on the pipe.

[0019] Preferably, a circular hole 11 is provided on the right side of the shell 10. The circular hole 11 is located on the right side of the shell 10. A gap is formed between the upper end of the circular hole 11 and the shell 10. The size of the circular hole 11 matches the thermocouple 30. The gap at the upper end of the circular hole 11 allows the thermocouple 30 to be fixed in the circular hole 11 while a part of the protrusion can directly contact the pipeline, thereby improving the measurement accuracy of the thermocouple 30.

[0020] The support partition 50 is installed inside the outer shell 10. The insulation layer 20 is bonded to the left and right sides of the support partition 50. A limiting hole 51 is also provided on the support partition 50. The limiting hole 51 on the support partition 50 is the same as the circular hole 11 at the right end of the outer shell 10.

[0021] Preferably, the support partition 50 is installed inside the shell 10, and a limiting hole 51 is also provided on the support partition. The limiting hole 51 on the support partition 50 is the same as the circular hole 11 on the right side of the shell 10. The insulation layer 20 is glued to the left and right sides of the support partition 50. The support partition 50 not only helps to stabilize the shape and position of the insulation layer 20, but also ensures that the thermocouple 30 can be firmly installed inside the device, thereby improving the convenience of installation.

[0022] The heat insulation layer 20 is made of aerogel and is installed inside the shell 10 . The heat insulation layer 20 is adhered to the inner wall of the shell 10 by adhesive.

[0023] Preferably, the thermal insulation layer 20 is made of aerogel, the thickness of the thermal insulation layer 20 is adapted to the circular hole 11, and the thermal insulation layer 20 is installed on the inner side of the outer shell 10. The thermal insulation layer 20 is adhered to the inner wall of the outer shell 10 by an adhesive. The aerogel itself has excellent thermal insulation properties and is easier to adhere to the small outer shell 10. In addition, the presence of the thermal insulation layer 20 also protects the thermocouple 30 from direct erosion by high temperature, thereby extending the service life of the device.

[0024] The thermocouple 30 passes through the circular hole 11 on the right side of the housing 10 , and the thermocouple 30 is located above the thermal insulation layer 20 ; the fixing plates 40 are divided into four, and the fixing plates 40 are welded to the top of the housing 10 .

[0025] Preferably, the thermocouple 30 is a wire with a diameter of 2 to 4 mm. The thermocouple 30 passes through the circular hole 11 on the right side of the outer shell 10 and the limiting hole 51 on the supporting partition 50, and is located above the thermal insulation layer 20. The thermocouple 30 with a diameter of 3 mm can be better installed with the device, and has low cost and good measurement effect, and can adapt to the needs of various installation and measurement environments.

[0026] In this embodiment, the aerogel constituting the thermal insulation layer 20 is cut according to the size of the shell 10, and the aerogel is adhered to the inside of the shell 10 and the supporting partition 50 using an adhesive. The thermocouple 30 is then passed through the circular hole 11 on the right side of the shell 10 and the limiting hole 51 on the supporting partition 50. The protruding part of the thermocouple 30 through the notch at the upper end of the circular hole 11 is then adhered to the pipe to be measured. After the heating plate is placed on the other side of the shell 10, the heating plate, the shell 10 and the thermocouple 30 are all fixed to the pipe with wire. After the circuit calibration is completed, the temperature change is measured after the power is connected.

[0027] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will appreciate that the present application may have other optimization schemes and additional functions. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
