Abstract
The utility model provides a novel cathode carbon block for an aluminium electrolysis cell, which has the characteristic that a molten aluminium layer can exist between the bottom of the cathode carbon block for the aluminium electrolysis cell and a heat preservation anti-leakage layer. The novel cathode carbon block for the aluminium electrolysis cell is mainly applied to construction in a conducting layer of a cathode conductive molten pool of the aluminium electrolysis cell. The novel cathode carbon block is characterized in that a concave-convex platform trough is arranged and constructed at the bottom surface part of the cathode carbon block; and a molten aluminium through hole or groove can be constructed on the cathode carbon block. After the aluminium electrolysis cell formed by the cathode carbon block provided by the utility model is adopted, due to the existence of the molten aluminium layer between the bottom of the cathode carbon block and the heat preservation anti-leakage layer, not only can the electrical conductivity of a cathode electric conductor be improved and the horizontal current of the aluminium electrolysis cell is eliminated, but also the fluctuation of magnetic rotational flow of molten aluminium is inhibited, the height of an electrolysis polar distance is reduced, the voltage drop of a cell bottom structure and the setting of the electrolysis process voltage are reduced, and the energy-saving production of the aluminium electrolysis cell is realized.

Summary of the invention; The present invention design provide a kind of can the aluminium electrolysis cell cathode carbon block bottom and heat-preservation and anti-leakage layer between have the aluminium liquid layer to exist novel aluminum cell use cathode block, be mainly used in interior the constructing of aluminium electrolytic cell cathode conduction molten bath conductive layer.
A kind of aluminium electrolysis cell cathode carbon block structure is characterized in that; The setting of cathode block bottom surface sections is configured with concavo-convex platform trough, and can on cathode block, be configured with aluminium liquid perforation hole or groove.
According to technique scheme, the cathode block bottom surface sections is provided with groove or the gradient that rises to fovea superior, and the bottom of cathode block is provided with carbon piece brace table.
According to technique scheme, the bottom of its cathode block is provided with the carbon piece support rim of structure, can process structure with the one of carbon piece, also can be divided into two parts and carry out composite construction.
According to technique scheme, the bottom of its cathode block is provided with the carbon piece support rim of structure.One end that can be arranged on the carbon piece also can be arranged on the two ends of carbon piece.
According to technique scheme, the current output terminal cage structure of its cathode block has to conduct electricity with the negative electrode conducting metal and is connected the carbon bowl, and promptly cathode steel bar inserts connecting hole.
According to technique scheme, its cathode block bottom surface sections has the recessed or inclination that makes progress to the electrolyzer center from electrolyzer sidepiece current output terminal.
According to technique scheme, be configured with aluminium liquid on its cathode block and connect hole, its aluminium liquid connects hole horizontal tectonics or vertical configuration on cathode block.
According to technique scheme, the textural structure of its cathode bottom is provided with aluminium liquid and connects groove, and aluminium liquid connects groove horizontal tectonics or vertical configuration on cathode block.
A kind of aluminium electrolysis cell cathode carbon block structure is mainly used in the aluminium electrolytic cell cathode conduction molten bath, and constructing of energy-saving aluminium cell that the aluminium liquid layer exists arranged between cathode block bottom and the heat-preservation and anti-leakage layer.The aluminium cell that adopts cathode block of the present invention to construct; Because the existence of aluminium liquid layer is arranged between the bottom of negative electrode cathode block and the heat-preservation and anti-leakage layer, not only can increase the conductivity of negative electrode electrical conductor, eliminate the horizontal current of aluminium cell; And can also suppress the fluctuation of aluminum liquid magnetic rotational flow; Lower the height of electrolysis pole span, reduce that the bottom land structure voltage falls and the setting of electrolysis process voltage, realize the energy-conservation production of aluminium cell.
