[0021] A rotating seat 26 is provided at the end of the moving rod 24, and the rotating seat 26 is slidably connected to the insulation board 27. One side of the insulation board 27 is rotatably connected to the insulation bin 2 through the rotating seat 26. When the moving rod 24 starts to move forward, the moving rod 24 can push the rotating seat 26 to move downward, and the top of the insulation board 27 is rotatably connected to the insulation bin 2 through the rotating seat 26. The insulation board 27 can be rotatably connected to the opening of the insulation bin 2. The forward movement of the moving rod 24 can push the partition 27 to open outward, so that the heat near the insulation bin 27 can enter the insulation bin 2, making it convenient for the user to check the temperature using the temperature sensor 42.

[0022] A shell 3 is provided on the side of the mounting plate 12, and a pipe 4 is penetrated in the shell 3. The pipe is penetrated in the furnace shell and the shell. A temperature sensor 42 is provided in the pipe 4, and a valve 41 is provided outside the pipe 4. The temperature sensor 42 can display the detected temperature in real time. After detecting the temperature, the internal temperature of the insulation bin 2 can be discharged to the outside by closing the insulation board 27 and opening the valve 41 of the pipe 4. The temperature inside the insulation bin 2 is exchanged, and closing the valve 41 of the pipe 4 can avoid the loss of the internal temperature of the insulation bin 2 during the temperature detection process, thereby affecting the accuracy of the detected temperature.

[0023] The shell 3 is provided with a water tank 31, and the water tank 31 is connected to a water pump 33 through a water pipe 32. The other side of the water pump 33 is connected to a heat exchange tube 35 through a water pipe 32. The heat exchange tube 35 is wound around the outside of a heat exchange block 36. The heat exchange block 36 is provided with a pipe 4. The top of the water tank 31 is connected to an external cold water pipe. A drain port is provided on the side of the water tank 31. By turning on the external power switch of the water pump 32, the water pump 32 can extract cold water from the water tank 31, and the cold water enters the heat exchange tube 35 through the water pipe 32.

[0025] In the above solution, a handle 22 is fixedly provided at the outer end of the screw rod 21, and the screw rod 21 is easily rotated by the handle 22.

[0026] In the above scheme, an isolation chamber 23 is provided inside the heat insulation chamber 2, and an outer rod 25 is fixedly provided on the isolation chamber 23. The isolation chamber 23 is fixedly provided with an outer rod 24, and the fixed setting of the outer rod 24 enables the moving rod 24 to move.

[0027] In the above solution, a slide groove 28 is provided on the heat insulation plate 27 , and the slide groove 28 is slidably connected to the rotating seat 26 . The provision of the slide groove 28 facilitates the movement of the rotating seat 26 .

[0028] Working principle:

[0029] The temperature measuring device for the furnace shell of the lead smelting bottom blowing furnace, when it is necessary to detect the temperature inside the furnace shell 1 and near the oxygen gun 11, by rotating the screw 21, the rotation of the screw 21 can move the moving rod 24 forward, push the insulation board 27 to rotate outward, so that the temperature inside the furnace body can enter the insulation bin 2, and the temperature sensor 42 inside the insulation bin 2 detects and displays the temperature. When the detection is completed, the screw 21 is rotated in the opposite direction, so that the insulation board 27 can be engaged with the opening of the insulation bin 2, and the valve 41 above the pipeline 4 is opened, so that the temperature in the insulation bin 2 can be discharged outward, and the water pump 33 switch is turned on at the same time. The water pump 33 can draw cold water to take away the heat of the heat exchange block 36, accelerate the cooling of the pipeline 4, and the cooling of the pipeline 4 can reduce the temperature inside the insulation bin 2, so as to avoid the temperature sensor 42 from being exposed to high temperature for a long time and affecting the service life.
