Aluminum electrolysis cell provided with continuous anode

Abstract

The invention provides an aluminum electrolysis cell provided with a continuous anode. The aluminum electrolysis cell comprises an electrolytic cell, a cathode which is arranged at the bottom of the electrolytic cell, and a continuous anode component which is arranged on the electrolytic cell, wherein the continuous anode component comprises an anode metal shell of which the lower end is opened, and an anode body which is arranged inside the anode metal shell; the lower end part of the anode body extends out of the opening of the lower end of the anode metal shell; the circumferential side, extending out of the anode metal shell, of the anode body is provided with a plurality of electrode bars; the anode metal shell is provided with an anode feeding hole for filling a particle mixed raw material; the circumferential side the opening of the lower end is also provided with a plurality of cutting components for cutting the anode body so that the height of the anode body can be reduced. The aluminum electrolysis cell provided with the continuous anode needs not to repeatedly replace an incomplete anode, so a continuous anode technique is realized and environmental pollution is reduced as well.

Description

technical field [0001] The invention relates to the technical field of electrolytic cells, in particular to a continuous anode electrolytic cell for aluminum electrolysis. Background technique [0002] Since the adoption of the Hall-Heroult alumina molten salt electrolytic aluminum smelting method in 1886, the global aluminum electrolysis industry has experienced continuous production processes of small prebaked anode aluminum electrolysis cells, self-baked anode aluminum electrolysis cells, and then large prebaked anode aluminum electrolysis cells. Explore and improve the development and application process. [0003] Although the prebaked anode aluminum electrolytic cell is the technical mainstream of aluminum smelting methods in the world today. However, with the rise of international and domestic raw materials and the changing trend of the production cost of the aluminum electrolysis industry caused by energy shortages, the traditional aluminum electrolysis cell producti...

AI Technical Summary

Problems solved by technology

The structure cannot adopt the intermediate point automatic feeding technology, the size of the prebaked anode is too large and it is difficult to replace it, and the quality requirements for the special bonding paste are very high, etc.

[0006] In addition, there have been patents for the production process of anode fixtures and prebaked anode bonding in China, but there are also defects such as inconvenient installation and replacement of continuous prebaked anodes, and it is not conducive to improving the anode current distribution.
