Abstract
The utility model discloses a melting pool for an aluminium electrolysis cell, and the melting pool can be used for solving the problems that cracks are easy to generate on the peripheries of cathode carbon blocks contained in the lining of the vertical electricity-input and electricity-output aluminium electrolysis cell, and the fluctuation of molten aluminium is easy to cause due to the upper surfaces of the carbon blocks, thus increasing electricity consumption. The melting pool for the aluminium electrolysis cell comprises an electrolysis cell shell and the lining, wherein the inner surface of the electrolysis cell shell is fitted with the outer surface of the lining, and at least one aluminium storage groove or aluminium arrangement lug is arranged on the bottom of the lining; the aluminium storage groove is a concave cylindrical surface, a concave spherical surface, a concave rotary paraboloid, a concave ellipsoid, a concave plane or an inverted-herringbone-shaped concave inclined surface; the aluminium arrangement lug is a convex cylindrical surface, a convex spherical surface, a convex rotary paraboloid, a convex ellipsoid, a convex plane or a herringbone-shaped concave inclined surface. The lining of the electrolysis cell does not contain anode carbon blocks and cannot generate electrochemical corrosion, so that the leakage of the molten aluminium caused by conductive holes can be avoided; the lining has less possibility of generating cracks, so that the occurrence of a runout phenomenon can be avoided.
Description
Technical field
This utility model relates to a kind of electrolysis of aluminum cell lining structure technology, particularly relates to a kind of aluminium cell molten bath.
Background technology
The main generation equipment of modern aluminum industry is aluminium cell, the basic process of production is that riser bus bar, the positive bar by the groove side enters carbon anode with direct current, electrochemical reaction occurs in the interface in carbon anode and sodium aluminum fluoride electrolyte melt, the alumina eltrolysis that is dissolved in the sodium aluminum fluoride electrolyte melt is become liquid metal aluminium, deposit to bottom of electrolytic tank, carbon anode constantly consumes and discharges carbon dioxide on anode.Direct current at the liquid metal aluminium of flowing through, flow through carbon cathode below it again, the cathode steel bar from the both sides, long limit of electrolyzer along equal number flows out electrolyzer.Aluminium cell exists in groove in process of production up to higher than the fused electrolyte of 1000 ℃ and the aluminium liquid more than 900 ℃.In the electrolysis production process, the powerful electric current of hundreds thousand of amperes will be flow through in bottom, electrolyzer molten bath, and bottom cathode charcoal piece is under the effect of electrochemical reaction, the crack can appear, ionogen or aluminium water can infiltrate from the crack of cathode carbon pieces, destroy inner lining structure, finally form the electrolyzer runout.
After improving, the electric mode of electrolytic process employing level turnover, cell lining does not contain cathode carbon pieces, can avoid the leakage that exists conductive hole to cause, and liner is not easy to occur the crack, can avoid the generation of runout phenomenon.Can eliminate because there being cathode carbon pieces simultaneously, the aluminium liquid that the horizontal tectonics of charcoal piece upper surface causes cathode inner lining top is under the strong-electromagnetic field effect that the powerful electric current of hundreds thousand of amperes produces, produce aluminum liquid magnetic rotational flow, cause the fluctuation of aluminium liquid, thereby cause the setting of ionogen pole span to increase, voltage is set and is strengthened the technique power consumption increase that causes electrolytic aluminum.When being provided with storage aluminium groove or row's aluminium projection bottom liner, the lower that the aluminium liquid of generation can in time be gathered in liner is pumped, and can prevent too much aluminium liquid gathering, avoids metal wave.
The utility model content
The utility model has overcome in prior art vertical turnover electrit cell lining and has contained cathode carbon pieces, the problem that crack and charcoal piece upper surface easily cause the fluctuation increase power consumption of aluminium liquid easily occurs around the charcoal piece, provide a kind of durable in use, the electrit electrolyzer molten bath of liner not perforate of bottom.
Technical solution of the present utility model is, provide a kind of aluminium cell molten bath with following structure: contain electrolytic cell housing and liner, the outside surface of electrolytic cell housing internal surface applying liner, the bottom of described liner are provided with 1 storage aluminium groove or row's aluminium projection at least.Storage aluminium groove is recessed cylinder, concave spherical surface, the recessed paraboloid of revolution, concave ellipsoidal surface, concave plane or the herring-bone of the falling face that concaves.Recessed cylinder and the herring-bone of the falling face that concaves is vertical, horizontal or arranged askew, and is described vertically parallel with the long limit in molten bath.Row's aluminium projection is projection face, protruding sphere, the protruding paraboloid of revolution, protruding ellipsoid, convex flat face or herring-bone convex inclined plane.Projection face and herring-bone convex inclined plane are vertical, horizontal or arranged askew, and be described vertically parallel with the long limit in molten bath.Liner contains lagging material, refractory materials, seepage resistant material and corrosion resistant material.
Compared with prior art, the utility model aluminium cell molten bath has the following advantages: after improving, cell lining does not contain cathode carbon pieces, do not produce galvanic corrosion, can avoid the leakage that exists conductive hole to cause, liner is not easy to occur the crack, can avoid the generation of runout phenomenon.The horizontal tectonics that can eliminate simultaneously the cathode carbon pieces upper surface causes the aluminium liquid on cathode inner lining top under the action of a magnetic field, produce aluminum liquid magnetic rotational flow and form metal wave, thereby the current efficiency of increasing substantially increases primary aluminum output.Can also simplify in a large number the busbar arrangement of aluminium cells when saving electric energy, save a large amount of aluminiums.The utility model is simple in structure, saves material, and long service life has good society and economic benefit.
