Five-end-riser aluminum electrolysis tank bus configuration structure

Abstract

The invention discloses an aluminum electrolysis tank five-end-riser bus configuration structure. Five riser side column buses and five bar side column buses are arranged; the five riser side column buses are connected with two groups of large anode buses of an upper portion of a tank, and the two groups of the large anode buses are connected with twenty groups of anodes, twenty groups of cathode carbon blocks and twenty groups of cathode steel rods respectively; flue end riser side cathode buses (2), middle riser side cathode buses (4) and aluminum outlet end riser side cathode buses (5) are connected through twenty groups of flexible cathode buses (1) welded to a cathode steel rod at the riser side, and are connected with four column buses (11) of the downstream tank through tank side portion buses (7) and a tank bottom through bus (8) of the electrolysis tank respectively; and bar side cathode buses (10) are connected through twenty groups of flexible anode buses (9) welded to the cathode steel rod at the bar side, and anode buses at the bar side are connected with the four column buses (11) of the downstream tank through horizontally or vertically folding the cathode buses.

Description

technical field [0001] The invention relates to a configuration structure of a magnetic fluid stable busbar for a large-scale aluminum electrolytic cell, in particular to a busbar configuration structure for a five-point power-feed aluminum electrolytic cell. Background technique [0002] With the development of my country's aluminum industry production technology, the series current intensity of modern large-scale aluminum electrolytic cells is increasing day by day. According to the description of Faraday's law, when other conditions are equal, the magnetic field will increase with the increase of current. However, the electromagnetic force generated by the interaction between the magnetic field generated by the production current of the electrolytic cell and the melt current in the electrolytic cell accelerates the circulation of the melt in the cell, causing the aluminum liquid surface to bulge, deflect and fluctuate, and may even affect the normal production of the elect...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a five-point power-feeding aluminum electrolytic cell bus configuration structure, which can not only achieve a good magnetic field compensation effect, but also save the amount of bus bars around the tank, thereby overcoming the insufficient magnetic field compensation existing in the prior art. The bias current phenomenon changes the magnetic properties in the tank and the flow of the melt, resulting in damage to the stability of the electrolytic tank and other deficiencies.
