Description

Technical Field

[0001] This utility model relates to the field of electrolysis, and in particular to an electrode plate loading and unloading system. Background Technology

[0002] Currently, in the electrolysis field, the removal and loading of electrode plates from and into cells are mainly completed by factory cranes and manual labor, which is labor-intensive. Moreover, electrode plates are currently removed in batches, and between the electrode plates, a copper busbar is required to achieve inter-cell short circuit or power-off operation to prevent accidental power-on.

[0003] Taking electrolytic nickel / cobalt as an example, the electrode spacing for nickel and cobalt is generally 140mm, and the cycle time from the electrode to the tank is 6-9 days. Cathode plates are divided into two types: starting plates and nickel / cobalt seed plates. Currently, a single electrolytic cell typically contains 40-50 cathode plates. When the number of cathode plates loaded and unloaded in a single operation is ≥20, a bridging copper busbar is used to achieve inter-cell short circuits, ensuring smooth current transmission.
