Description

Technical Field

[0001] The utility model relates to the technical field of chemical detection, in particular to a temperature measuring device for a titanium dioxide calcining kiln. Background Art

[0002] Titanium dioxide is an important inorganic chemical pigment, primarily composed of titanium dioxide. Rotary kilns used to produce titanium dioxide are typically tens of meters long. Based on the material's characteristics, strict process requirements exist for the length and temperature of the three sections. The stability of the three-section temperature has a direct impact on the final quality of the calcined product. Controlling the rotary kiln production process essentially involves adjusting the temperature and length of the three sections to ensure they operate according to the ideal process temperature distribution curve. Accurate temperature field measurement is essential for controlling the rotary kiln's temperature field.

[0003] At present, when measuring the temperature of titanium dioxide calcining kilns, most of the time only the internal temperature is detected, and the temperature of the outer wall cannot be detected. Once a heat source leaks, a safety accident may occur. In addition, since the shape of the outer wall of the calcining kiln may change, different temperature measurement facilities cannot be effectively fixed.

[0004] Therefore, we made improvements and proposed a temperature measuring device for titanium dioxide calcining kiln. Utility Model Content

[0005] In order to solve the problem that the existing temperature measuring device cannot measure the temperature outside the kiln and is inconvenient to fix the temperature measuring facilities at different positions outside the kiln, the utility model provides a temperature measuring device for a titanium dioxide calcining kiln.

[0006] The utility model is achieved in this way:

[0007] A temperature measuring device for a titanium dioxide calcining kiln comprises a calcining kiln body, four fixed blocks are respectively installed on the sides of the outer wall of the calcining kiln body, wherein a lead screw is rotatably connected between two of the fixed blocks, one end of the lead screw is threadedly connected to a sweeping mechanism, one side of the sweeping mechanism is interpenetrated with a limit rod, the two ends of the limit rod are respectively connected to one side of the other two fixed blocks, a laser thermometer is provided on one side of the outer wall of the sweeping mechanism, the detection end of the laser thermometer faces the outer wall of the calcining kiln body, the outer wall of the calcining kiln body is provided with a fixing mechanism, and one side of the fixing mechanism is interpenetrated with a temperature measuring component in the kiln.

[0008] Furthermore, the ring-sweeping mechanism includes an outer ring, a sliding box, a gear, a gear ring and a second motor. The outer wall of the outer ring is slidingly connected to the sliding box, the interior of the sliding box is rotatingly connected to the gear, the outer wall of the outer ring is embedded with a gear ring, and the gear ring is engaged with the gear.

[0009] The beneficial effect of adopting the above further solution is that by causing the gear to rotate inside the sliding box and coordinating the meshing relationship between the gear ring and the gear, the sliding box can drive the laser thermometer to perform circular motion on the outer ring.

[0010] Furthermore, a second motor is installed on the outer wall of the sliding box, and an output end of the second motor is transmission-connected to one end of the gear.

[0011] The beneficial effect of adopting the above further solution is that, by installing and using the second motor, it provides power for the rotation of the gear.

[0012] Furthermore, the fixing mechanism includes a square arc plate, a first circular hole and a first bolt. The first circular hole is set on one side of the square arc plate. The square arc plate is inserted and connected with the first bolt on the side close to the first circular hole. The square arc plate is connected to the outer wall of the calcining kiln body through the first bolt.

[0013] The beneficial effect of adopting the above further solution is that, by connecting the square arc plates, it is fixed on the arc-shaped outer wall of the calcining kiln body, thereby facilitating the assembly of the temperature measuring component in the kiln in the middle of the calcining kiln body.

[0014] Furthermore, the fixing mechanism includes a circular straight plate, a second circular hole and a second bolt. The second circular hole is set on one side of the circular straight plate. The circular straight plate is inserted and connected with the second bolt on the side close to the second circular hole. The circular straight plate is connected to the outer wall of the calcining kiln body through the second bolt.

[0015] The beneficial effect of adopting the above further solution is that, by connecting and using the circular straight plates, it can be fixed on both sides of the calcining kiln body, thereby facilitating the assembly of the temperature measuring assembly in the kiln at the end of the calcining kiln body.

[0016] Furthermore, a first motor is installed on one side of the outer wall of the fixed block, and an output end of the first motor is transmission-connected to one end of the lead screw.

[0017] The beneficial effect of adopting the above further solution is that, by installing and using the first motor, power can be provided for the forward and reverse rotation of the lead screw.

[0018] Furthermore, the temperature measuring assembly in the kiln includes a temperature measuring body, a temperature measuring rod and a thermocouple. The sensing end of the temperature measuring body is connected to the temperature measuring rod. One end of the temperature measuring rod extends into the interior of the calcining kiln body and is connected to the thermocouple.

[0019] The beneficial effect of adopting the above further solution is that, by connecting and using the thermocouple, the temperature measuring component in the kiln can be directly inserted into the calcining kiln for real-time temperature monitoring.

[0020] Furthermore, a notch is provided on one side of the bottom end of the sliding box.

[0021] The beneficial effect of adopting the above further solution is that, by providing the notch, the sliding box is prevented from being obstructed when performing a circular rotation around the outer wall of the outer ring.

[0022] The beneficial effect of the present invention is that through the coordinated use of the fixed block, the lead screw, the limiting rod, the circular sweeping mechanism and the laser thermometer, the temperature measuring device can monitor the temperature outside the kiln in real time, thereby ensuring the safety of the use of the calcining kiln. Specifically, by prompting the lead screw to rotate forward and reverse and cooperating with the limiting effect of the limiting rod, the circular sweeping mechanism can move back and forth on the outside of the calcining kiln body, and then through the installation and use of the laser thermometer, it can perform circular motion driven by the circular sweeping mechanism, thereby facilitating temperature monitoring of any position on the outer wall of the calcining kiln body, and the coordination of the fixed mechanism and the temperature measuring component in the kiln makes it possible to measure the temperature of multiple positions inside the calcining kiln body.
