Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell detection, in particular to an electrolytic cell temperature monitoring device. Background Art

[0002] The surface temperature of the electrolytic cell is an important indicator in aluminum electrolysis production. Excessive temperature may cause safety accidents such as damage to the electrolytic cell structure and splashing of molten metal. In the past, temperature measurement was entirely done manually, which had shortcomings such as inconsistent measurement, low accuracy, heavy workload, and lack of continuity, and it was impossible to grasp the temperature change trend.

[0003] Installing a temperature monitoring device can solve the problem of insufficient manual measurement, but the temperature monitoring device needs to be installed close to the electrolytic cell or in contact with the electrolytic cell. While ensuring the power supply of the monitoring device, it must be considered that it will not cause a grounding fault in the electrolytic cell. Battery power supply can solve some problems, but due to battery characteristics, the monitoring data will be non-real-time and discontinuous, and the electrolytic cell status cannot be fed back in a timely and accurate manner. It will also involve the workload of replacing batteries later. Utility Model Content
