A temperature measuring mechanism body 7 is provided in the middle of the upper end of the connecting ring 3. One end of the temperature measuring mechanism body 7 contacts one end of the temperature measuring rod body 1. The mounting column 4 is rotated to make the threaded tube 8 rotate in the connecting ring 3. When the threaded tube 8 is taken out of the connecting ring 3, the threaded tube 8 is separated from the elastic metal soft plate 17, and the restriction of the elastic metal soft plate 17 is released. The elastic force of the elastic metal soft plate 17 itself will separate each elastic metal soft plate 17, and the restriction of the temperature measuring rod body 1 is released, so that the temperature measuring rod body 1 can be taken out from the temperature measuring mechanism. The structural design of the elastic metal soft plate 17 and the threaded tube 8 is simple to operate, and the temperature measuring rod body 1 can be quickly replaced.

[0021] like Figure 1 - Figure 3 As shown, the upper end of the connecting ring 3 is fixedly connected with a protective shell 2 5, the inner bottom of the protective shell 2 5 is fixedly installed with one side of the outer wall of the temperature measuring mechanism body 7, the inner wall of the protective shell 2 5 is clamped with a protective shell 1 2, and the protective shell 1 2 and the protective shell 2 5 are used to protect the temperature measuring mechanism body 7 to prevent dust and water vapor from falling on the temperature measuring mechanism body 7.

[0022] like Figure 1 and Figure 3As shown, the outer wall of the protective shell 2 5 is fixedly connected with multiple disassembly columns 6, and the inner walls of the multiple disassembly columns 6 are slidably connected with fixing rods 10, and the outer walls of the multiple fixing rods 10 are sleeved with reset springs 11, one end of the reset spring 11 is in contact with one side of the inner wall of the disassembly column 6, and one end of the multiple fixing rods 10 is respectively engaged with one side of the outer wall of the protective shell 2, and the fixing rod 10 is pulled outward to release the restriction of the protective shell 2, and the staff then takes the protective shell 2 out of the protective shell 2 5, and then repairs the temperature measuring mechanism body 7 in the protective shell 2 5.

[0026] The utility model provides a temperature measuring mechanism for alumina microwave calcining tunnel kiln, and the specific working principle is as follows:

[0027] When the temperature measuring mechanism of the alumina microwave calcining tunnel kiln is used for a long time and the temperature measuring rod body 1 in the temperature measuring mechanism is damaged and needs to be replaced, the mounting column 4 is rotated to rotate the threaded tube 8 in the connecting ring 3. When the threaded tube 8 is taken out of the connecting ring 3, the threaded tube 8 is separated from the elastic metal soft plate 17, and the restriction of the elastic metal soft plate 17 is released. The elastic force of the elastic metal soft plate 17 will separate each elastic metal soft plate 17, and the restriction of the temperature measuring rod body 1 is released, so that the temperature measuring rod body 1 can be taken out of the temperature measuring mechanism, and then a new temperature measuring rod body 1 can be installed. The body 1 is inserted into the connecting ring 3, one end of the temperature measuring mechanism body 7 is clamped with one end of the temperature measuring rod body 1, and then the mounting column 4 is rotated in the opposite direction, the elastic metal soft plate 17 will clamp the temperature measuring rod body 1, and thus the installation is completed. When the temperature measuring mechanism body 7 needs to be maintained, the rotating handle 12 is turned, and the rotating handle 12 and the disassembly column 6 form a lever to pull the fixing rod 10 outward, thereby releasing the restriction of the protective shell 2. The staff will take the protective shell 2 out of the protective shell 5 and then maintain the temperature measuring mechanism body 7 in the protective shell 5.
