Description

Technical Field

[0001] This invention belongs to the field of aluminum electrolytic cell anode measurement technology, specifically relating to an aluminum electrolytic cell anode measurement and positioning device and its measurement method. Background Technology

[0002] The prebaked anode of the aluminum electrolysis cell consists of multiple carbon anodes, such as Figure 1 As shown, each anode 00 consists of an anode carbon block 01 with a thickness of approximately 60 cm, a steel claw 02, and an anode guide rod 03. During the electrolytic aluminum production process, the anode carbon block is continuously consumed, and its thickness decreases accordingly. When it is consumed to a certain extent, a new anode replaces the residual anode to ensure continuous aluminum electrolysis production. During electrode replacement, to avoid localized flow deviation in the electrolytic cell, the bottom of the new anode and the residual anode must be at the same height in the electrolytic cell, thus ensuring that the bottom of the entire prebaked anode is on a single plane after electrode replacement. Therefore, operators need to measure the overall height of the residual anode and determine the installation position of the new anode based on the measured overall height of the residual anode. In addition, the analysis of electrolytic cell production data also needs to refer to the thickness of the remaining anode carbon block in the residual anode. For example, by measuring the thickness of the residual anode at different locations in the electrolytic cell, the regularity of the electrolytic cell furnace can be analyzed.

[0003] The current method of measuring residual electrodes and locating new electrodes mainly relies on manual measurement and marking using a measuring tape, which is inefficient, prone to human error when drawing lines, and results in inaccurate positioning of new electrodes, affecting the stable operation of the electrolytic cell. In addition, since the temperature of residual electrodes can reach as high as 900℃, there are certain safety hazards in the measurement process. Summary of the Invention
