Description

Technical Field

[0001] The utility model belongs to the field of thermocouple equipment, in particular to a temperature measuring thermocouple for a baking furnace. Background Art

[0002] The roasting furnace temperature measuring thermocouple is a sensor used to measure the internal temperature of the roasting furnace. The roasting furnace temperature measuring thermocouple has the advantages of fast response speed, high measurement accuracy, good reliability, etc., and is widely used in temperature measurement and control in various industrial fields. In actual use, the current roasting furnace temperature measuring thermocouple has the problem that the temperature measuring rod is easily hit by slag during use. During the operation of the roasting furnace, slag will be generated under the high temperature environment in the furnace, and these slags may splash and hit the thermocouple in some cases. This will not only cause direct physical damage to the outer surface of the thermocouple's temperature measuring rod, resulting in a decrease in its measurement accuracy or even complete loss, because of the lack of protective components. The lack of protective components will not only lead to the above problems, but also the frequent slag hitting will shorten the service life of the thermocouple and increase the cost of maintenance and replacement. This has brought many inconveniences to industrial production. On the one hand, the damage of the thermocouple may lead to the interruption of temperature measurement, affecting the accurate judgment and regulation of the working state of the roasting furnace; on the other hand, frequent replacement of thermocouples will also consume a lot of manpower, material resources and time, and reduce production efficiency. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content
