Background technology
Metallic aluminium adopts fused salt electrolysis process to produce in industry, i.e. electrolytic dissolution is the aluminum oxide in the ionogen of staple at the fused sodium aluminum fluoride, and the main at present method that adopts is Hall-Ai Lu (Hall-Heroult) electrolytic process.
The direct equipment of producing electrolytic aluminum is electrolyzer, and electrolyzer mainly contains the two parts to be formed, and a part is an anode, is processed by carbon materials usually, and another part is a negative electrode, is built by laying bricks or stones by charcoal piece and inner lining material to form.
Aluminium cell is connected in the whole electrolytic series, and electric current gets into electrolyzer from anode, through the fused ionogen; Pass liquid aluminium liquid; Get into cathode carbon pieces, electric current is collected through the cathode steel bar that is assemblied in the cathode carbon pieces, imports next electrolyzer through negative busbar.
Existing cathode structure of aluminium cell is: cathode steel bar is equipped with in the bottom at cathode carbon pieces; All adopt between cathode steel bar and the charcoal piece and prick the modes of sticking with paste or watering ferrophosphorus and be connected; Each cathode carbon pieces is equipped with one or two cathode steel bars; Cathode steel bar and cathode carbon pieces be horizontal positioned in the same way, and the sidewall that an end of cathode steel bar stretches out electrolyzer is connected with negative busbar.The electrolyzer of this structure; There is a very large shortcoming in cathode conductive structure: because cathode steel bar and cathode carbon pieces horizontal positioned in the same way; Cause producing very large horizontal current in the aluminium liquid, the vertical magnetic field acting in conjunction produces electromagnetic force in this horizontal current and the aluminium liquid, and this electromagnetic force drives liquid aluminium liquid and in electrolyzer, flows and fluctuation; If the horizontal current in the electrolyzer is excessive and skewness; Will cause the fluctuation of aluminium liquid and electrolyte interface excessive, make electrolyzer produce serious unstable aborning, reduce current efficiency.In addition, horizontal current distributes along the length direction skewness of cathode carbon pieces in the aluminium liquid, makes that place, the end current density of cathode carbon pieces is maximum, thereby significantly accelerates the corrosion of cathode carbon pieces here, reduces the life-span of electrolyzer.
In order to improve the stability of electrolyzer, common way is the perpendicular field profile in the strict control aluminium liquid in the design of electrolyzer, and this has not only increased the negative busbar difficulty of design, and causes cathode arrangement complicated, and the bus consumption is big, and investment increases.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above the distribution of current in the homogenizing aluminium liquid, the stability of raising electrolyzer; Proposed the method for distribution of current in a kind of homogenizing aluminum cell aluminum liquor, its objective is the horizontal current that reduces in the aluminium liquid, made in the aluminium liquid distribution of current more even; Thereby significantly improve the stability of electrolyzer; Make electrolyzer significantly reduce a ton aluminium energy consumption efficiently and smoothly operated than hanging down under the pole span, the while cathode current density more becomes even; Reduce the speed of cathode abrasion, prolong cathode life.
To achieve these goals, the present invention realizes through following technical proposals:
The method of distribution of current in a kind of homogenizing aluminum cell aluminum liquor; Prick solid or at least one cathode steel bar of casting in the cathode carbon pieces bottom; Cathode steel bar is separated along its length and is sewn on different positions and is divided into several parts; Part between the cathode steel bar divide seam on every partitioning slot all adopts electrical conductor to be connected with cathode carbon pieces, and the cathode steel bar of rest part all adopts isolator and cathode carbon pieces to insulate, the interior employing of partitioning slot partitioning slot filling insulating material; Make partitioning slot two portions cathode steel bar insulation up and down, an end of cathode steel bar passes from the sidepiece of electrolyzer.
Described electrical conductor is carbon paste or ferrophosphorus.
Described cathode steel bar is partly pricked solid or is cast in the cathode carbon pieces.
The quantity of the partitioning slot in the described every cathode steel bar is 1 ~ 20.
The cross-sectional shape of described cathode steel bar is square, circular, semicircle, trapezoidal or trilateral.
1-50 root cathode steel bar is installed in described every group of cathode carbon pieces bottom.
Advantage of the present invention and effect are following: the present invention has very strong practicality, do not change negative electrode go out electric mode be sidepiece go out the electricity condition under, significantly reduced the horizontal current in the aluminium liquid; Homogenizing the distribution of current in the aluminium liquid; Increased substantially the stability of electrolyzer, prolonged cathode life, electrolyzer can be efficiently and smoothly operated under low pole span condition; Reduce ton aluminium energy consumption effectively, had obvious energy-saving effect.
