Controlled aluminum electrolysis cell anode covering sealing structure

Abstract

The invention discloses a controlled aluminum electrolysis cell anode covering sealing structure. The structure comprises a structural frame fixedly covering an electrolysis cell and a plurality of sealing plates laid on the structural frame, wherein a notch through which an anode guide rod passes and a blanking hole taken as a smoke channel are formed in each of part of sealing plates. Each sealing plate comprises a large surface side part sealing plate, an upper part anode break joint sealing plate, an end part sealing plate, a blanking hole sealing plate and an anode center joint sealing plate, wherein the large surface side part sealing plate is fixedly laid on the side surface of the long side of the structural frame, the end part sealing plate is movably laid on the end face of the short side of the structural frame, and the upper part anode break joint sealing plate, the blanking hole sealing plate and the anode center joint sealing plate cover the top of the structural frame. Compared with an existing mulch manner, the controlled aluminum electrolysis cell anode covering sealing structure has the advantages that labour intensity and production cost can be obviously reduced, electrolysis process control level is improved, continuous, stable and efficient production can be easily realized, smoke collecting efficiency is high, workshop environment is improved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a controllable aluminum electrolytic cell anode covering and sealing structure which replaces the aluminum oxide covering material structure on the traditional aluminum electrolytic cell, and belongs to the novel aluminum electrolytic cell technology. Background technique [0002] At present, during the electrolysis operation of the aluminum electrolytic cell, a layer of electrolyte and alumina covering material is covered on the anode of the electrolytic cell to keep the heat of the electrolytic cell and prevent the smoke from escaping from the side, causing deterioration of the operating environment. But this structure has the following problems: [0003] (1) During the pole change operation, since the covering material is consolidated into blocks, it needs to be mechanically broken by the air hammer of the crown block to carry out the follow-up operation, which is time-consuming and labor-intensive; after the pole change is ...
