Abstract
A cathode heterotypic conducting steel rod of an aluminum cell, wherein the whole conducting steel rod is divided into three sections, a left-right symmetrical current confluence section, a current adjusting section and a current derivation section. The utility model is characterized in that the current confluence section is arranged in the middle portion of the aluminum cell cathode heterotypic conducting steel rod and the upper surface of the current confluence section is a horizontal surface. The current adjusting section whose upper surface is an inclined surface is arranged between the current confluence section and the current derivation section. As the electrical conductivity of charcoal block is lower than that of the steel rod, the confluence section of the steel rod is wider and closer to the upper surface of the charcoal block and the electric resistance is relative small. The current adjusting section is an inclined surface and the resistance is gradually increased when the current passes through relative to the middle portion, thereby gradually reducing the gradually increasing current in the traditional steel rod when passing through this steel rod, enhancing current perpendicularity, effectively adjusting the cathode current direction, reducing the current horizontal component and the magnetic disturbance to the aluminum liquid layer, enhancing production efficiency, and furthermore being simple in structure, low in cost and fast in effect.
Description
Technical field:
The utility model relates to the used negative electrode electrical conductor of a kind of aluminium cell, the special-shaped conduction of particularly a kind of aluminium electrolytic cell cathode rod iron.
Background technology:
The used negative electrode electrical conductor of aluminum current electrolyzer all is to be combined by cathode carbon pieces and conduction rod iron, and vertical anodic current enters charcoal piece layer and rod iron after passing through ionogen, aluminium liquid layer, and level derives.Because the rod iron cross section is even, be embedded in the groove of charcoal piece, electric current is when vertical direction enters rod iron by the charcoal piece, because charcoal piece electroconductibility is far below rod iron, electric current can form the horizontal current to current output terminal of certain component in the charcoal piece when entering rod iron, the magnetic field that this electric current produces can produce the power of a fluctuation to the metallic aluminium liquid layer, cause the fluctuation of aluminium liquid layer, thereby influence electrolysis production, cause energy consumption height, inefficient problem.At present, large-scale aluminum electrolytic cell is very sensitive to influence of magnetic field, though bus series has been carried out a large amount of optimization, cathode current distribution is also unreasonable, and negative electrode conducts electricity intravital current direction and also do not reach requirement.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, easy for installation, can effectively adjust the cathode carbon pieces sense of current, solves current field to aluminium liquid layer exert an influence the energy consumption height that is caused, the special-shaped conduction of the aluminium electrolytic cell cathode rod iron of the low problem of efficient.
The technical solution of the utility model realizes by following method:
The special-shaped conduction of a kind of aluminium electrolytic cell cathode rod iron, it is an elongated conduction rod iron to be divided into the symmetrical electric current section of confluxing, electric current adjustment section and electric current derive section three parts, wherein: the electric current section of confluxing is positioned at aluminium electrolytic cell cathode special-shaped conduction rod iron middle part and upper surface is a horizontal plane, electric current adjustment section upper surface between electric current section of confluxing and electric current derivation section is an inclined-plane, the angle of inclination on inclined-plane is a=3-15 °, and the length of the electric current section of confluxing (L) is the 1/3-2/3 of conduction rod iron length overall.
Electric current is derived the thickness of section, electric current adjustment section less than the electric current section of confluxing.
The positively effect that the technical solution of the utility model reached is:
Because the electroconductibility of charcoal piece is far below rod iron, the rod iron section of confluxing is thicker up and down, nearer with charcoal piece upper surface, resistance is less relatively, electric current adjustment section is an inclined-plane, the logical out of date resistance of electric current increases gradually with respect to the middle part, reduced gradually the time thereby make traditional rod iron flow through the electric current that increases gradually herein by this kind rod iron, thus the verticality of raising electric current.Can effectively adjust the cathodic current direction, reduce the horizontal component of electric current, reduce magnetic interference, enhance productivity the aluminium liquid layer.Simple in structure, improvement cost is low, instant effect.

Fig. 4: traditional rod iron current direction schematic diagram.
Embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is described further:
By Fig. 1, Fig. 2 as can be seen, the special-shaped conduction of this aluminium electrolytic cell cathode rod iron, it is that an elongated conduction rod iron is divided into the symmetrical electric current section of confluxing 1, electric current is adjusted section 2, derive section 3 three parts with electric current, wherein: the electric current section of confluxing 1 is positioned at the special-shaped conduction of aluminium electrolytic cell cathode rod iron middle part, and upper surface is a horizontal plane, it is to a downward inclined-plane, end that electric current between electric current section of confluxing 1 and electric current derivation section 3 is adjusted section 2 upper surfaces, the angle of inclination on inclined-plane is a=3-15 °, the surface by the middle part on inclined-plane is near from the charcoal piece, outside more far away more, the logical out of date resistance of electric current is increased gradually with respect to the middle part, thereby making traditional rod iron flow through the electric current that increases is gradually herein reduced by this kind rod iron the time gradually, improve the verticality of electric current, the length of the electric current section of confluxing 1 (L) is the 1/3-2/3 of conduction rod iron length overall.
As seen from Figure 3, the rod iron section of confluxing 1 is thicker, and the section surface that confluxes is near from the charcoal piece, and resistance is less relatively, part conduct current middle part.
As seen from Figure 4, electric current is when vertical direction enters rod iron by the charcoal piece, because charcoal piece electroconductibility is far below rod iron, electric current can form the horizontal current to current output terminal of certain component in the charcoal piece when entering rod iron.
