Abstract
The utility model relates to Al cell with TiB cathode construction. The cathode construction of the utility model is inserted in the cathode carbon block with TiB casting bars or casting bars with TiB as the base, the end points of the cathode construction are penetrated through the cathode carbon block and are directly cast with cast-iron or tamped with carbonaceous paste to keep together. Owing to good electric conduction performance of TiB, the utility model has the functions of reducing the cathode drop of the cathode tank and power consumption. At the same time, because most of the electric current flows across the TiB casting bars, the electric current flowing across the cathode carbon blocks is little, the electrolytes penetrating the electrolytic tank bottom is reduced, and the service life of the electrolytic tank can be enhanced.
Description
The utility model belongs to field of metallurgy, is specially adapted to the aluminium cell of a kind of novel cathode structure of sodium aluminum fluoride one alumina molten salt electrolysis system aluminium.
The negative electrode of aluminum current electrolyzer is built by laying bricks or stones with the charcoal piece, and the outer cathode steel bar of pot shell that stretches out of the bottom of this charcoal piece group and bottom of electrolytic tank links together and constitutes the negative electrode electrical conductor of electrolyzer.But because charcoal piece resistance is bigger, and porous, a large amount of ionogen that infiltrate in the electrolytic process, the groove pressure drop that makes electrolyzer is about just often up to 450mv, therefore power consumption is bigger, simultaneously, the charcoal piece is swelled, cause the electric tank cathode well damage owing in electrolytic process, penetrate into a large amount of ionogen of bottom land with the refractory materials of bottom land reacts.
The purpose of this utility model provides a kind ofly can significantly fall end electric tank cathode pressure drop, and can improve the aluminium cell of the novel titanium boride cathode structure in electric tank cathode life-span.
The utility model is realized with following scheme.In cathode carbon pieces, embed some titanium borides or be the founding rod of base with the titanium boride, and the cathode steel bar that penetrates cathode carbon pieces and bottom land is connected, during ordinary production, through most of electric current of negative electrode aluminium liquid via titanium boride or titanium boride be the founding rod importing cathode steel bar of base.Because titanium boride conducts electricity very well, thereby makes the volts lost of negative electrode fall the end.And because the big portion of electric current is via titanium boride founding rod, and the electric current by cathode carbon pieces seldom, thereby the ionogen that electric osmose is gone into cloudy charcoal piece can significantly reduce, and the life-span of electrolyzer is with regard to corresponding increase.
Be further described below in conjunction with accompanying drawing.
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is the sectional view of A-A direction of the present utility model.
Wherein (9) are the electrolyzer pot shells, and (1) is cathode carbon pieces, and (3) are cathode steel bars, and (2) are titanium borides or are the founding rod of base with the titanium boride.(2) embed in the cathode carbon pieces (1) and pass and be connected with the cathode steel bar (3) of bottom land.Founding rod (2) is that cylinder iron (4) casting is connected with cathode steel bar (3), and (6) are trough side part charcoal piece among the figure, is that the charcoal paste is made body (5) firm by ramming between limit portion charcoal piece (6) and the cathode carbon pieces (1).Between the bottom of cathode carbon pieces (1) and pot shell (9) refractory materials and lagging material (8).Between the bottom land refractory materials of electrolyzer and lagging material (8) and limit portion charcoal piece (6), refractory concrete or structure of refractory (7) are arranged.When ordinary production, the titanium boride founding rod (2) and because the electric current major part is flowed through because titanium boride founding rod is an inert to molten aluminum, thereby can fall the kerve volts lost greatly and reduce the infiltration of ionogen to cathode carbon pieces, so can fall the power consumption that end aluminium cell is produced, the work-ing life that can improve electrolyzer again.
As embodiment, titanium boride or be the founding rod (2) of base with the titanium boride, embed in the cathode carbon pieces (1) with the direction at the bottom of the vertical electrolytic bath, and select the density inserted according to the size reasonable of electrolyzer, to guarantee the reasonable distribution of cathodic current, founding rod (2) penetrates cathode carbon pieces (1), its end points is cylinder iron poured into a mould with cathode steel bar (3) or charcoal is stuck with paste to make firm by ramming and is connected, consider at the bottom of the cathode drop influence simultaneously to aluminium electrolysis process, suitably adjust operating procedure, just can significantly fall the energy consumption in the end Aluminium Electrolysis, and can prolong the life-span of electrolyzer.
Claims (2)
1, a kind of aluminium cell of novel titanium boride cathode structure, stick with paste by electrolytic bath shell, cathode carbon pieces, anode rod iron, charcoal and to make body etc. firm by ramming and form, it is characterized in that in the cathode carbon pieces some titanium borides of embedding people or be the founding rod of base with the titanium boride and directly be connected with cathode steel bar.
2, plumbous electrolyzer according to claim 1 is characterized in that titanium boride or titanium boride embed in the anode carbon block for the direction of founding rod at the bottom of with vertical channel of base, and penetrates cathode carbon pieces, and its end points is cylinder iron poured into a mould with cathode steel bar or charcoal is stuck with paste to make firm by ramming and is connected.
