Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrolytic cell current guiding devices, specifically an emergency current guiding device for the cathode current of an aluminum electrolytic cell. Background Technology
[0002] Due to national "dual-carbon" strategy and tiered electricity pricing policies, energy conservation and emission reduction have become important development directions for the electrolytic aluminum industry. The direct welding technology of aluminum-steel cathodes in aluminum electrolytic cells can further reduce energy consumption in electrolytic aluminum production and has begun to be promoted and experimentally applied in various production projects within the domestic electrolytic aluminum industry. Direct welding of aluminum-steel cathodes involves welding aluminum sheets to the ends of the cathode steel rods, then welding flexible strips through the aluminum sheets, and finally connecting the flexible strips to the cathode busbars. Due to process limitations, direct welding of aluminum-steel cathodes cannot be performed on steel surfaces exceeding 300°C. If, during normal electrolytic cell production, extreme circumstances cause cracking of the direct welding layer, repair welding will be impossible. If left untreated, this will alter the cathode current distribution in the aluminum electrolytic cell, affecting normal production. If multiple sets of direct welding layers crack without intervention, the aluminum electrolytic cell will shut down, resulting in severe economic losses. Therefore, how to urgently restore current conduction after cracking of the direct welding layer is a problem that needs to be solved. Utility Model Content
[0003] The main objective of this invention is to provide an emergency current diversion device for the cathode of an aluminum electrolysis cell, in order to solve the problem of how to urgently restore current diversion after the direct weld layer of the aluminum-steel cathode cracks in the prior art.
[0004] To achieve the above objectives, this utility model provides an emergency current diversion device for the cathode of an aluminum electrolysis cell, comprising an aluminum flexible strip, with aluminum blocks fixedly connected to both ends of the aluminum flexible strip, and an adjustable-length support rod connected between the two aluminum blocks via a ball-head hinge.
[0005] Furthermore, the aluminum block has a slot, and a C-shaped plate is inserted into the inside of the aluminum block, with the C-shaped plate connected to a ball joint hinge.
[0006] Furthermore, the support rod is a turnbuckle.
[0007] Furthermore, an aluminum plate is fixedly connected to the aluminum strip, and an aluminum block is fixedly connected to the aluminum plate; the outer end of the aluminum plate extends outward from the aluminum block, and the aluminum plate and the aluminum block form an L-shaped outer edge.
[0008] The emergency current diversion device for the cathode of this utility model can, after the cathode aluminum-steel direct weld layer cracks, place two aluminum blocks against the cathode steel rod and the cathode busbar respectively, so that the cathode current can be diverted through the aluminum blocks and aluminum soft strip, thus avoiding the problem of the aluminum electrolysis cell shutting down due to the cracking of the cathode aluminum-steel direct weld layer, which would cause serious economic losses.
[0009] This utility model uses a support rod to hold the aluminum block against the cathode steel rod and cathode busbar; by setting a ball joint hinge, the angle between the support rod and the aluminum block can be adjusted from multiple directions; by setting a C-shaped plate and a slot, the support rod and aluminum block can be easily installed and disassembled; the aluminum plate and aluminum block form an L-shaped outer edge; the outer edge of the L-shape is used to support and fit against the cathode steel rod and cathode busbar.
