Embodiment 1
[0022] Such as figure 1 As shown, a temperature measuring device for a rotary kiln radiant tube includes a rotary kiln shell 1, a radiant tube 2, a temperature measuring conduit 3, and a thermocouple 4. The radiant tube 2 is located in the rotary kiln shell 1, and the radiant tubes 2 are parallel to each other. On the center line of the rotary kiln shell 1, the temperature measuring conduit 3 runs through the rotary kiln shell 1, the thermocouple 4 is arranged in the temperature measuring conduit 3, and runs through the temperature measuring conduit 3 along the axis, the temperature measuring conduit 3 and The thermocouples 4 are all perpendicular to the radiation tube 2 , the center line of the temperature measuring conduit 3 is tangent to the outer wall of the radiation tube 2 , and the temperature measuring probes of the thermocouples 4 are in contact with the radiation tube 2 under the guidance of the temperature measuring conduit 3 .

Embodiment 2
[0028] Such as figure 2 As shown, this embodiment is an improvement on the basis of Embodiment 1. The difference from Embodiment 1 is that the temperature measuring device also includes a thermocouple shield 5, and one side of the thermocouple shield 5 is open, so One side of the opening is arc-shaped, and the arc size of the arc is consistent with the arc size of the outer wall of the radiant tube 2. The end of the temperature-measuring conduit 3 extending into the kiln body extends into the thermocouple shield 5, and is connected with the thermocouple shield 5. The thermocouple shield 5 is fixed together, and the arc surface of the thermocouple shield 5 is closely attached to the outer wall of the radiation tube 2 to protect the thermocouple 4 temperature measuring probe. The thermocouple shield 5 The environment where the thermocouple probe is located is consistent with the surface temperature of the radiation tube here, and the accuracy of temperature measurement is guara...
Embodiment 3
[0030] Such as image 3 As shown, this embodiment is an improvement made on the basis of embodiment 2. The difference from embodiment 2 is that the thermocouple 4 is provided with a junction box at the outer end of the rotary kiln shell 1, and at the One end of the box 41 is provided with an external thread 42 , and one end of the temperature measuring conduit 3 outside the rotary kiln shell 1 is provided with an internal thread 33 corresponding to the external thread 42 .
