Recurvation-prevention aluminum electrolysis cell upright column flexible bus bar

Abstract

The invention relates to a recurvation-prevention aluminum electrolysis cell upright column flexible bus bar, comprising an upper part upright column flexible bus bar and a lower part upright column flexible bus bar, the front end of the upright column flexible bus bar is connected with an anode large bus bar, the rear end thereof is connected with a connecting block; the recurvation-prevention aluminum electrolysis cell upright column flexible bus bar has main points that one or a plurality of arc-shaped steel plates which are arranged side by side are arranged between the upper part uprightcolumn flexible bus bar and the lower part upright column flexible bus bar, a bottom steel plate is arranged at the lower end of the arc-shaped steel plate, and a steel belt is tied up around the upright column flexible bus bar; as the structure has good supporting function to the upright column flexible bus bar, the stretching of the anode large bus bar can be effectively avoided owning to the recurvation of upright column flexible bus bar caused by overhigh temperature and self weight, the tensile stress and stress deformation of the anode large bus bar are reduced, the safety operation of an aluminum electrolysis cell is ensured; as the upright column flexible bus bar can not be recurved, enough operation space under the upright column flexible bus bar is ensured.

Description

Technical field: [0001] The invention relates to a column soft busbar for an aluminum electrolytic cell, in particular to an aluminum electrolytic cell column soft busbar for preventing downward bending. Background technique: [0002] Most modern large-scale prebaked anode aluminum electrolytic cells adopt a large-scale multi-point power supply method, and the number of large-scale column busbars is generally 4 to 7. The column soft busbar connects the column hard busbar and the anode busbar together, and direct current is introduced from the column to the anode busbar for production by the electrolytic cell. [0003] The column soft bus bar is generally divided into two parts in the width direction, and each part is divided into two parts in the up and down direction, that is, the entire column soft bus bar is divided into four parts, and there is a gap of about 20mm between the adjacent two parts. It is composed of more than a dozen bundles of soft belts, and each bundle ...

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide an anti-bending aluminum electrolytic cell column soft busbar to solve the problem that the column soft busbar is bent down due to high temperature during the electrolytic production process, resulting in a large impact on the anode. Increased tensile stress of the busbar and reduced operating space
