CELL BOTTOM STRUCTURE OF REDUCTION CELL

摘要

The present invention discloses a cell bottom structure of a reduction cell which comprises a reduction cell (1) and a cathode bus (2), wherein the bottom of the reduction cell (1) is provided with column-shaped cathode carbon blocks (3) perpendicular to the bottom of the reduction cell (1), and a lower end of the column-shaped cathode carbon block (3) is connected to the cathode bus (2). By means of inserting the column-shaped cathode carbon blocks perpendicular to the bottom of the reduction cell and connecting the lower end of the column-shaped cathode carbon block with the cathode bus, such that electrical current that guided from anode carbon blocks is guided through the molten aluminum to the column-shaped cathode carbon blocks and is downwardly guided out, the present invention reduces horizontal electrical current in the molten aluminum, such that the cathode extending into the molten aluminum can effectively reduce fluctuations of the molten aluminum to obtain a stable surface of the molten aluminum, thereby reducing a polar distance between a cathode and an anode and lowering cell voltage so as to achieve the object of lowering electricity consumption.
