Abstract

The invention discloses a method of adding aluminium fluoride into the aluminium electrobath and its device. It adopts the wind-driving sluice to add the alumina and aluminium fluoride to the enriching box of the aluminium electrobath at the same time. That is the material of alumina and aluminium fluoride is input into the wind-driving sluice at the same time. Mixing them in the wind-driving sluice and then putting them into the material box and then into the aluminium electrobath. The advantages are simple structure and reliable work, increasing the useful life of the electrobath.

Description

Technical field:

[0001] The invention relates to a method and a device for adding aluminum fluoride raw materials to an aluminum electrolytic cell, and belongs to the technical field of aluminum fluoride feeding to an aluminum electrolytic cell. Background technique:

[0002] At present, in the prior art, when adding aluminum fluoride to the aluminum electrolytic cell, the aluminum fluoride material box is generally installed on the electrolytic cell, and then the aluminum fluoride raw material in the aluminum fluoride material box is added to the aluminum electrolytic cell In the upper feeding box, the aluminum fluoride raw material is added to the aluminum electrolytic cell through the feeding box. The aluminum fluoride feeding method in the prior art mainly exists that the aluminum fluoride cannot be mixed with the aluminum fluoride before entering the upper feeding box of the electrolytic cell. The disadvantage of sufficient mixing of alumina raw materials is that it is ...
