Background technology
China's aluminum electrolyzation technology development is very fast, particularly in nearly 20 years, the electrolyzer capacity is increased sharply to 500kA by 180kA, but because traditional cell construction does not almost have variation fundamentally, the current efficiency of electrolytic process has only increased less than 3% in these 20 years, direct current consumption has only reduced not enough 700kWh/t.
Production practice show that traditional electrolysis tech is difficult in stably manufactured under the 4.0V bath voltage.For the electrolyzer of traditional structure, if do not making a breakthrough aspect improvement cell construction, material behavior and the raising electrolyzer hydromagnetic stability, it almost is impossible reducing bath voltage significantly.
Electrolyzer is when work, and electric current from top to bottom arrives on the cathode carbon pieces by dielectric substrate, aluminium liquid layer from anode, and the aluminium cell on the our times is shunted to electrolyzer two side bus by cathode steel bar after electric current arrives cathode carbon pieces.Traditional aluminum electrolytic cell bottom has only field compensation bus and short-circuit busbar, can not be applicable to that bottom land goes out the aluminium cell of electricity.After bottom electricity-outlet aluminium electrolytic bath cathode rod iron passes from bottom of electrolytic tank, how to be connected with negative busbar and can not to produce magnetic field greatly to melt in the electrolyzer, such negative electrode goes out electric structure does not also have solution at present.
The utility model content
By Given this, the purpose of this utility model provides a kind of aluminium electrolytic cell cathode and goes out electric installation, has overcome the deficiencies in the prior art, and rational in infrastructure, easy construction, distribution of current and Distribution of Magnetic Field are reasonable.
To achieve these goals, the utility model is by the following technical solutions:
A kind of aluminium electrolytic cell cathode goes out electric installation, wherein, comprise negative electrode square steel head, transition section, cathode soft bus and bottom land bus, described negative electrode square steel head vertically passes the pot shell base plate, and negative electrode square steel head end head is an inclined-plane, and transition section comprises steel section and aluminium section, the inclined-plane of steel section and negative electrode square steel head adopts steel plate successively to weld, aluminium section and cathode soft bus welding, the cathode soft bus the other end and the welding of bottom land bus, the bottom land bus is arranged on the bus buttress.
Further, two negative electrode square steel heads on the described same negative electrode are arranged on the different bottom land buses.
Further, two negative electrode square steel heads on the described same negative electrode are arranged on the same bottom land bus.
The beneficial effects of the utility model are:
1, can conveniently adjust cathode current distribution by the cross section and the length of regulating cathode soft bus and bottom land bus, avoid producing that horizontal current causes because of electric current branch is uneven, the melt fluctuation problem, thus increase primary aluminum output, save electric energy;
2, can conveniently adjust the Distribution of Magnetic Field of melt in the aluminium cell by changing bottom land bus position, make electrolysis production steady, simplify production specifications, and can increase substantially current efficiency;
3, the utility model is simple in structure, and easy construction is applied widely, has good society and economic benefit.
