Description

TECHNICAL FIELD

[0002] The boiler thermocouple is an important sensor for measuring the temperature in the boiler, which can convert the temperature inside the boiler into an electrical signal, so as to realize the accurate control of temperature. In the operation process of the boiler, the role of the thermocouple is crucial, because it can help the operator to understand the temperature condition inside the boiler in time, so as to take corresponding measures to ensure the safe and stable operation of the boiler. In the long-term operation process of the thermocouple, especially in the harsh working conditions of high temperature, high sulfur and high ash content, the probe part of the thermocouple is prone to form coking, which seriously affects the accuracy and stability of temperature measurement.

[0003] At present, the traditional way to remove the coking thermocouple is basically to knock it off with external force. When the thermocouple cannot be taken out, it will be knocked into the furnace, and it may also be impossible to knock, resulting in the inavailability of the thermocouple measuring point position, which affects the walking of the grate, the control of the material layer and the slag removal system. If it is an environmental protection monitoring thermocouple, it may also cause environmental protection accidents. The force during knocking is completely applied to the fins and tube rows of the water wall, which can cause serious harm to the water wall. UTILITY MODEL CONTENT

Since the hollow piston rod 103 is hollow in the middle, when the thermocouple is disassembled, the thermocouple can pass through the hollow piston rod 103, so that the thermocouple does not interfere with the hollow piston rod 103. One end of the outer cylinder 101 is provided with a cylinder cover 105. An oil cavity 104 is formed between the outer cylinder 101 and the hollow piston rod 103.
