Thermocouple mechanism for multi-module high-temperature ceramic firing

Abstract

The thermocouple mechanism comprises a junction box, an insulation sleeve protection tube, a thermode, a fixing plate and a furnace wall, one end of the junction box is connected and provided with the insulation sleeve protection tube, the bottom end of the insulation sleeve protection tube is connected and provided with the thermode, the furnace wall is provided with a wall hole, the thermode is inserted into the wall hole, and the fixing plate is connected with the thermode. Adjusting boxes are symmetrically installed on the top face of the fixing plate, lifting grooves are symmetrically formed in the side faces of the opposite sides of the adjusting boxes, lifting plates are clamped and embedded in the lifting grooves, nuts are installed at one ends of the lifting plates, threaded rod shafts are installed in an inner cavity of one adjusting box, and the threaded rod shafts are meshed with the nuts. The device has the function that the installation connecting piece can be detached after being away from the furnace wall and cooled, workers are prevented from being scalded when the thermocouple is detached and replaced, the safety is higher, the use angle of the junction box in the installation state can be conveniently adjusted, and the wiring efficiency of installation personnel is improved.

Description

technical field [0001] The invention relates to the technical field of temperature measurement for firing high-temperature ceramics, in particular to a thermocouple mechanism for firing multi-module high-temperature ceramics. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument. In the process of firing high-temperature ceramics, the temperature It is one of the important parameters that need to be measured and controlled, so a multi-module high-temperature ceramic firing thermocouple mechanism is now used for temperature monitoring in high-temperature ceramic firing production. [0003] When a traditional multi-module high-temperature ceramic firing thermocouple mechanism is disassembled, worke...

AI Technical Summary

Problems solved by technology

[0003] When a traditional multi-module high-temperature ceramic firing thermocouple mechanism is disassembled, workers often need to directly contact the thermocouple close to the furnace wall. Due to the high furnace temperature, the temperature of the installation and connection parts is generally also high. There is a greater risk of being burned during disassembly, which brings inconvenience to the disassembly of a multi-module high-temperature ceramic firing thermocouple mechanism. In addition, a traditional multi-module high-temperature ceramic firing thermocouple mechanism is installed and fixed. Most of them cannot adjust the angle of the junction box. When the wiring direction changes greatly, the installer often needs to disassemble and reinstall the entire thermocouple mechanism, which brings inconvenience to the wiring work of a multi-module high-temperature ceramic firing thermocouple mechanism.
