Abstract

Настоящее изобретение описывает электролитическую ячейку для электролиза алюминия, содержащую корпус ячейки, где анод и катод располагаются внутри корпуса ячейки, кроме того, корпус ячейки заполнен электролитом, и по меньшей мере часть анода погружена в электролит; анод располагается выше корпуса ячейки, катод располагается на днище электролитической ячейки, и он покрыт некоторым количеством жидкого алюминия, между анодом и катодом располагается электролит, и он покрывает жидкий алюминий; и изолирующий слой располагается на внутренней боковой стенке корпуса ячейки и используется для изоляции кислорода или электролита от углеродного блока. Электролитическая ячейка для электролиза алюминия отличается тем, что анод содержит компоненты, включая Fe, Cu, Ni и Sn, где Fe и Cu служат в качестве первичных компонентов; и электролит состоит из 30-38 мас.% NaF, 49-60 мас.% AlF, 1-5 мас.% LiF, 1-6 мас.% KF и 3-6 мас.% AlO, где молярное отношение NaF к AlFсоставляет 1,0-1,52. Электролитическая ячейка может использоваться для получения промышленного электролитического алюминия.The present invention describes an electrolytic cell for the electrolysis of aluminum, comprising a cell body, where the anode and cathode are located inside the cell body, in addition, the cell body is filled with an electrolyte, and at least part of the anode is immersed in the electrolyte; the anode is located above the cell body, the cathode is located on the bottom of the electrolytic cell, and it is covered with some liquid aluminum, the electrolyte is located between the anode and the cathode, and it covers the liquid aluminum; and the insulating layer is located on the inner side wall of the cell body and is used to isolate the oxygen or electrolyte from the carbon block. The electrolytic cell for aluminum electrolysis is characterized in that the anode contains components including Fe, Cu, Ni and Sn, where Fe and Cu serve as primary components; and the electrolyte consists of 30-38 wt.% NaF, 49-60 wt.% AlF, 1-5 wt.% LiF, 1-6 wt.% KF and 3-6 wt.% AlO, where the molar ratio of NaF to AlF is 1.0-1.52. The electrolytic cell can be used to produce industrial electrolytic aluminium.
