Horizontal current aluminium cell

Abstract

The invention discloses a horizontal current aluminum electrolytic bath. The aluminum electrolytic bath comprises a melting bath part and an electrode part, wherein the melting bath part consists of a steel bath shell(5) and fire proof and heat proof materials(10); the upper end of the bath shell(5) adopts an open type structure; while the electrode part consists of a cathode electrode part and an anode electrode part, wherein the cathode electrode part consists of a cathode electrode(6), a cathode electrically conductive pole(4) and a cathode bus(2) applied to discharge electric current, and the anode electrode part consists of an anode electrode(7), an anode electrically conductive pole(3) and an anode bus(1) applied to charge electric current; the electrode part are hanged in the bath shell(5) by a support steel beam, and a liquid electrolyte layer (8) is arranged between the cathode electrode(6) and the anode electrode(7); electrolytic currents horizontally enter the corresponding side face of the cathode electrode(6) from the side face of the anode electrode(7). The aluminum electrolytic bath has the advantages that the design is novel, no electric current pass through the melting bath, no electrochemical reaction happens, the aluminum electrolytic bath does not need to be drilled around, along with long service life and good social and economic benefits.

Description

Horizontal current aluminum electrolytic cell Technical field: The invention relates to an aluminum electrolytic cell, in particular to a horizontal current aluminum electrolytic cell, which belongs to the field of electrolytic cell structures. Background technique: At present, the direction of the electrolytic current in the electrolytic cell used in the production of electrolytic aluminum industry is vertical, that is, the current flows from the anode at the upper part of the electrolytic cell vertically to the cathode at the bottom. The problems that exist in this way are: 1. A strong current of hundreds of thousands of amperes flows through the bottom of the molten pool of the electrolytic tank. Under the action of electrochemical reaction, the carbon cathode at the bottom expands and breaks, which keeps the life of the electrolytic tank at about 1800 days. 2. The electrolytic cell passes through a strong current of hundreds of thousands of amperes, which will gener...

Problems solved by technology

The capacity of the electrolytic cell is large, and the structure of the busbars entering and exiting the electrolytic cell is complex, so that there will be magnetic fields in different directions, in which the magnetic field generated by the horizontal current will interact with the magnetic field generated by the vertical current in the aluminum liquid, causing the aluminum liquid layer to fluctuate. Resulting in lower production efficiency of aluminum electrolysis
