Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis production, in particular to an anode guide rod detection device. Background Art

[0002] Anode guide rods are important consumable parts in the production of prebaked electrolytic cells. They play a dual role in transmitting current and hanging anode carbon block groups in aluminum electrolysis production and are used cyclically.

[0003] The anode guide rod is composed of an aluminum guide rod, an explosive welding block and a steel claw welded in sequence. During production, the anode guide rod is always in a high-temperature environment in the electrolytic cell, which can easily cause defects such as inward bending of the claw head, erosion and burning of the claw head, or erosion, oxidation and thinning; when replacing the anode guide rod, improper operation can easily cause defects such as bending and deformation of the aluminum guide rod, cracking of the explosive welding block weld and cracking of the explosive block. The above defects will lead to a reduction in the contact area between the aluminum guide rod and the anode balance busbar, an increase in the voltage drop at the node, an increase in the reactive power consumption of electric energy, and even the inability to install the anode guide rod on the electrolytic cell, affecting normal production. These defective anode guide rods need to be taken offline for repair or scrapped.

[0004] At present, the main method for inspecting anode guide rods is manual visual inspection. A detection point is set at a certain position of the anode guide rod hanging conveyor line, and the aluminum guide rod, explosion weld and steel claw are manually visually inspected. The defective anode guide rod is manually operated by the control box to be diverted to the guide rod correction, steel claw correction and offline maintenance conveyor line.
