Description

Technical Field

[0001] The utility model relates to the field of nonferrous metal nickel electrolysis technology, in particular to a two-pole four-contact conductive copper busbar device applied to a nickel electrolysis system. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] Due to the continuous improvement of the technical level of nickel electrolysis system, the traditional two-stage two-contact inter-slot conductive copper bar can no longer meet the production needs. Multiple groups of cathode and anode plates of the two-stage two-contact conductive copper bar are arranged in parallel in one electrolytic cell. When the resistance of a single group of contacts increases, the current flowing through will decrease, the current intensity will be different, and the current distribution will be uneven, resulting in substandard product weight and thickness. The voltage drop caused by the increase in resistance of each contact point requires additional external voltage compensation, resulting in increased electrical power (P=IU) and increased power consumption.

[0004] Therefore, it is necessary to design a two-pole four-contact conductive copper busbar device for nickel electrolysis system with uniform current distribution, high current efficiency, small contact resistance, small voltage drop and reduced power consumption. Utility Model Content

[0007] In one embodiment, the copper rod clamping slot of the bottom main conductive copper bar is arranged on the top of the bottom main conductive copper bar.

[0008] In one embodiment, the copper rod clamping slot of the top-layer auxiliary conductive copper busbar is arranged on the top of the top-layer auxiliary conductive copper busbar.

[0009] In one embodiment, the insulating spacer is disposed on top of the intermediate insulating plate.

[0010] In one embodiment, the arc of the copper bar clamping slot of the bottom main conductive copper bar and the copper bar clamping slot of the top auxiliary conductive copper bar are the same.

[0011] In one embodiment, the tops of the copper rod clamping slots of the bottom main conductive copper bar and the copper rod clamping slots of the top auxiliary conductive copper bar are at the same level.
