Abstract
The utility model relates to a draw-off TiB2-black-lead composite cathode aluminium electric tank. The cathode base element is made of carbon material. The surface of the electric tank is provided with a TiB2-black-lead composite layer with certain thickness. The surface of the cathode has an inclined degree ranging from 10 degrees to 30 degrees. The surface of anode also has a certain inclined degree, and the inclined degree is constant to that of the surface of the cathode. The arraying and distributing of the anode and the cathode are constant to that of traditional prebaked-anode electric tank. The utility model has the advantages of vastly decreasing the power consumption of aluminum electrolysis, and increasing the current density of the electric tank and the yield of the aluminum electrolysis.
Description
The utility model belongs to technical field of aluminum electrolysis, particularly a kind of drainage type TiB
2-graphite composite material inert cathode aluminium cell.
Aluminium is produced with fused salt electrolysis process.Aluminium Electrolysis needs a large amount of electric energy, and generally about 15000 degree electricity, its power consumption accounts for about 1/3rd in the aluminium production cost for one ton of metallic aluminium of average every electrolysis production, the electric energy that is consumed.Aluminium cell is a reactor that productivity is very low, and a strength of current is the large scale electrolytic cell of 200KA, and its day output also has only about 1.5 tons.Therefore develop and a kind ofly can reduce power consumption significantly, have high current density and large-duty electrolyzer is metallurgy of aluminium scientific worker's target always.
The purpose of this utility model is to provide a kind of drainage type TiB that can reduce the electrolysis of aluminum power consumption, increase substantially current density and electrolytic aluminum output
2-graphite composite material inert cathode aluminium cell.
Its matrix of negative electrode of the present utility model is made by carbon materials, and its upper layer is with having certain thickness TiB
2-graphite composite material is made.The cathode surface that is built into this carbon piece have along the longitudinal direction limit portion low, middle high in high outer low obliquity, its obliquity is between 10-30 °.The electric tank cathode surface does not keep aluminium liquid during ordinary production.The aluminium that electrolysis generates is owing to have the wettability good with graphite composite material, can flow down along the cathode surface that tilts, and be pooled in the collection aluminium chamber of groove center or limit portion, behind the certain interval of time, after waiting to collect aluminium in the aluminium chamber and reaching certain capacity, it is extracted out with vacuum ladle.Anode is the prebaked anode carbon piece made from after-smithing petroleum coke, and the prebaked anode carbon piece of the prebaked cell that uses with present industrial cell is the same, and different is that its basal surface has certain obliquity, the size of its obliquity and TiB
2The size of-graphite cathode surface tilt degree is consistent.The utility model anode, cathode arrangement are identical with traditional prebaked cell with layout.
The utility model can reduce the electrolysis of aluminum power consumption significantly, improve current density and electrolytic aluminum output.
