Description

Technical Field

[0001] The utility model relates to the technical field of aluminum processing heat treatment, and relates to a thermocouple assembly structure of a heat treatment furnace. Background Art

[0002] Heat treatment furnace is a new type of heat treatment heat exchange equipment, mainly used for annealing, heating and other processes of aluminum and aluminum alloys; heating methods include electric heating, oil, gas, coal, hot air circulation, etc., and temperature control is the key factor of the heat treatment furnace. In order to ensure that the heat treatment process meets production requirements, a thermocouple device is usually installed in the heat treatment furnace to measure and monitor the temperature of the workpiece during the heat treatment process, thereby realizing temperature control under the furnace differential temperature control mode.

[0003] Thermocouple is a commonly used temperature measuring element, mainly used for high temperature measurement, so it is widely used in heat treatment furnaces; however, the existing thermocouples are non-standard in design and production, and need to be fixedly connected to the cylinder.

Usually, thermocouples of different lengths cannot be used interchangeably, which brings inconvenience to use. At the same time, after a single thermocouple fails, the cylinder needs to be disassembled as a whole to replace the single thermocouple, which is difficult to maintain, time-consuming and labor-intensive. Frequent disassembly and assembly can easily affect the sealing performance in the furnace, which is not conducive to enterprise production. Utility Model Content
