[0002] Gas fuels are a general term for gaseous fuels that are mainly used in civil and industrial fields to release heat through combustion. They mainly include four categories: natural gas, manufactured gas, liquefied petroleum gas (LPG), and biomass gas. According to their source, natural gas includes gas field gas and associated petroleum gas, manufactured gas includes forms such as dry distilled coal gas and gasified coal gas, liquefied petroleum gas is mainly composed of propane and butane, and biomass gas is produced through biomass fermentation.

[0003] In the prior art, the temperature inside a gas-fired heat treatment furnace is detected by probe contact. This method only detects the inside of the furnace and does not take into account the connected pipelines. This results in a small detection range and an inability to understand the overall temperature situation. Therefore, those skilled in the art have provided a gas-fired heat treatment furnace temperature measuring device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a temperature measuring device for a gas-fired heat treatment furnace to solve the problems mentioned in the background art.

[0006] As a further embodiment of this utility model: the emission assembly includes symmetrically through-holes on both sides of the installation pipe, and a second fan and an electric telescopic rod are fixedly embedded in the vent holes respectively. The electric telescopic rod is arranged horizontally, and a sealing plug is fixedly connected to the telescopic end of the electric telescopic rod. The sealing plug is inserted into the inlet of the vent hole.

[0007] As a further improvement of this utility model: a first fan is fixedly embedded in the bottom opening of the mounting tube, and the first fan is located below the second temperature probe.

[0008] As a further embodiment of this utility model: a connecting seat is fixedly connected to the top of the mounting tube, and the connecting seat surrounds the transmission line, and the vent hole is connected to the top of the connecting seat.

[0009] As a further improvement of this utility model: a sealing ring is fixedly sleeved on the outer wall of the mounting tube, and multiple anti-slip protrusions are arranged in an arc shape on the inner wall of the clamping ring.

[0010] As a further improvement of this utility model: the two electric telescopic rods are arranged horizontally, and the electric telescopic rods are located below the second fan.

[0011] As a further improvement of this utility model: a rectangular groove is provided at the bottom of the connecting block, the first temperature probe is fixedly embedded in the rectangular groove, and both the first temperature probe and the second temperature probe face downwards.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the hot smoke comes into contact with the second temperature probe, the temperature can be measured through the second temperature probe. The transmission line is connected to the second temperature probe to transmit the temperature measurement data. After the two second fans and the electric telescopic rod are started, the electric telescopic rod can drive the sealing plug to extend and release the seal on the vent inlet. The second fan can draw the smoke into the vent through the vent inlet and finally discharge it through the vent outlet. The first temperature probe will come into contact with the outer wall of the pipeline, which can measure the temperature of the outer wall of the pipeline.

[0014] This invention is simple to use. The first and second temperature probes can measure the temperature of the outer wall of the pipeline and the inside of the furnace, respectively. This expands the temperature measurement range to understand the overall temperature of the furnace and pipeline, thereby improving the accuracy of temperature detection. Activating the first fan can quickly draw in the flue gas inside the furnace to contact the second temperature probe for detection. Activating the electric telescopic rod and the second fan can quickly discharge the flue gas for the next test. Attached Figure Description
