Description

Technical Field

[0001] This invention relates to the field of aluminum electrolysis technology, specifically to a temperature measurement system and method for the bottom of an aluminum electrolysis cell. Background Technology

[0002] When an electrolytic cell approaches the end of its service life, the aluminum smelter will shut it down for a major overhaul. This shutdown will interrupt production, affecting aluminum output. Especially when aluminum prices are high, shutdowns can cause significant losses for the aluminum smelter. Therefore, it is crucial to minimize these losses and extend the lifespan of the electrolytic cells as much as possible.

[0003] However, since the lifespan of an electrolytic cell cannot be predicted with great precision, prematurely shutting down the cell when it is nearing the end of its service life will result in economic losses, while continuing to use it will lead to safety risks such as cell leakage. Therefore, effectively monitoring the temperature of the cathode area, which is prone to leakage, and issuing early warnings for abnormal temperatures when the electrolytic cell is nearing the end of its service life is an effective way to simultaneously reduce economic losses and safety hazards. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a temperature measurement system for the bottom of an aluminum electrolytic cell, which reduces the occurrence of cell leakage accidents by monitoring the temperature of the electrolytic cell.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature measurement system for the bottom of an aluminum electrolysis cell, comprising an infrared thermometer, a gimbal, a processor, and a reflector. The infrared thermometer is mounted on the gimbal and arranged on one side of the electrolysis cell. The infrared thermometer is communicatively connected to the processor. The reflector is mounted on the side upright plate of the cradle frame of the electrolysis cell. The electrolysis cell is provided with a temperature measuring port, which is arranged between adjacent side upright plates of the cradle frame.

[0006] Furthermore, the reflector includes an angle adjustment component and a reflector plate, with one end of the angle adjustment component fixedly connected to the side upright plate of the cradle frame and the other end connected to the reflector plate.

[0007] Furthermore, the angle adjustment component also includes two electric telescopic rods, a fixed rod, and a universal joint. One end of the fixed rod is fixedly connected to the side upright plate of the cradle frame, and the other end is fixedly connected to the universal joint, which is connected to the bottom of the reflector. The fixed end of the electric telescopic rod is hinged to the fixed rod, and the extended end of the electric telescopic rod is connected to the ball joint at the bottom of the reflector.

[0008] Furthermore, the axes of the two electric telescopic rods are projected onto the horizontal plane at a 90° angle.

[0009] Furthermore, the infrared thermometer has a measurement range of 200℃ to 1000℃ and an object distance ratio of 200:1.

[0010] Furthermore, the control accuracy of the gimbal is 0.05° to 0.1°.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model uses an infrared thermometer and a reflector. By adjusting the angle of the pan-tilt unit and the reflector, the infrared thermometer can receive the infrared radiation reflected from the temperature measuring port by the reflector, thereby realizing the monitoring of the temperature at the bottom of the electrolytic cell; and two electric telescopic rods and a universal joint are set up, so that the reflector can be adjusted at multiple angles by telescopic movement of the electric telescopic rods in different directions.

[0018] Example 1

[0019] like Figures 1 to 2 As shown, this utility model provides a temperature measurement system for the bottom of an aluminum electrolytic cell, including an infrared thermometer 1, a pan-tilt unit 2, a processor 3, and a reflector. The infrared thermometer 1 is mounted on the pan-tilt unit 2 and arranged on one side of the electrolytic cell 4. The infrared thermometer 1 is communicatively connected to the processor 3. The reflector is mounted on the side upright plate 5 of the cradle frame of the electrolytic cell 4. The electrolytic cell 4 is provided with a temperature measuring port 6, which is arranged between adjacent side upright plates 5 of the cradle frame.

[0020] By adjusting the angles of the gimbal 2 and the reflector, the infrared thermometer 1 can receive the infrared radiation reflected from the temperature measuring port 6 by the reflector, thereby enabling the monitoring of the bottom temperature of the electrolytic cell 4.

[0021] Specifically, the reflector includes an angle adjustment component and a reflector plate 7. One end of the angle adjustment component is fixedly connected to the side upright plate 5 of the cradle frame, and the other end is connected to the reflector plate 7. The reflector plate 7 is made of mirror-polished stainless steel to reflect heat radiation and reduce heat radiation absorption. The angle of the reflector plate 7 is adjusted by the angle adjustment component.

[0022] Specifically, the angle adjustment component also includes two electric telescopic rods 8, a fixed rod 9, and a universal joint 10. One end of the fixed rod 9 is fixedly connected to the side upright plate 5 of the cradle frame, and the other end is fixedly connected to the universal joint 10, which is connected to the bottom of the reflector 7. The fixed end of the electric telescopic rod 8 is hinged to the fixed rod 9, and the extended end of the electric telescopic rod 8 is connected to the bottom ball joint of the reflector 7. The axes of the two electric telescopic rods 8 are projected at a 90° angle on the horizontal plane.

[0023] The angle is adjusted by the cooperation of two electric telescopic rods 8 at 90°. Each electric telescopic rod 8 realizes the adjustment of a plane angle. When one is working and the other is not working, the plane angle is rotated. When both are working at the same time, the two can be used together to realize the adjustment of the spatial angle. In addition, with the use of the universal joint 10, the reflector 7 can rotate around the center point of the universal joint 10 in space, so as to adjust the detection range of the reflector 7 corresponding to the infrared thermometer 1.

[0024] Specifically, the infrared thermometer 1 has a measurement range of 200℃ to 1000℃ and an object distance ratio of 200:1; the gimbal 2 has a control accuracy of 0.05° to 0.1°. The use of a high-precision gimbal 2 ensures accurate angle adjustment, and the gimbal 2 features a dustproof and high-temperature resistant design.

[0025] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
