Abstract
The present invention discloses asymmetric type groove bottom buses and a current distributing style. Current flowing from a cathode soft bus flows into the groove bottom buses of both sides of an electrolytic groove using a y shaft as a central line and a groove side bus of the electrolytic groove in non-uniform distribution, wherein the amount of the current flowing into the groove bottom bus approximating to a smoke channel end (right side) and the groove side bus is higher than the amount of the current flowing into the groove bottom bus approximating to an aluminum-outputting end (left side). Because the asymmetric type distribution of the groove bottom buses and the current are adopted, the present invention can effectively lower a magnetic field generated by the electrolytic groove and overcome the influence of the temporary groove magnetic field. Therefore, the effects of clipping a peak and smoothing by filling of the magnetic field in the groove are achieved, magnetic field gradient in the groove becomes small, and the uniformity of magnetic fluid is greatly enhanced.
Description
Technical field
The present invention relates to the collocation method of busbar arrangement and electric current around the groove in a kind of Aluminum Electrolysis Production.
Background technology
The tankage of modern prebaked-anode type cell is towards large scale development, and the magnetic field of electrolyzer increases with the increase of tankage, and its influence is also more and more important.Be subjected to the restriction of floor space and investment, array pitch between two (several) row electrolyzer generally can not be excessive, the rising of the vertical magnetic field that causes owing to column pitch is less causes the interface of melt in the groove to take place seriously to disturb the ordinary production of electrolyzer (especially large-scale groove) than great fluctuation process.
Summary of the invention
The objective of the invention is to: a kind of asymmetric bottom land busbar arrangement and current arrangements method are provided, can reduce the magnetic field that electrolyzer self produces, can overcome again and face the influence that is listed as the slot field.
The present invention is achieved in that asymmetric bottom land bus current collocation method, it is in the both sides bottom land buses (3) and groove side bus (2) of medullary ray with the Y-axis that the even distribution of the effusive current unevenness of cathode soft bus (4) flows into electrolyzer (1), wherein the magnitude of current that flows into by flue end (right side) bottom land bus (3) and groove side bus (2) is many than the magnitude of current of aluminium inlet (left side), and first bottom land bus (5) of the flue end (right side) of electrolyzer (1) is connected the 1st～3 cathode soft bus (4) the scope place of this side.
Electrolyzer (1) is gone into the effusive magnitude of current of 1～5 cathode soft bus (4) by the bottom land bus (3) and the groove side bus (2) of flue end (right side) than the multithread by aluminium inlet (left side).
Asymmetric bottom land busbar arrangement of the present invention is: it is made up of electrolyzer (1), bottom land bus (3), cathode soft bus (4) and groove side bus (2), and the bottom land bus (3) of the flue end (right side) of electrolyzer (1) is put 1～3 than the polygamy of aluminium inlet (left side); First bottom land bus (5) of the flue end (right side) of electrolyzer (1) is connected the 1st～3 cathode soft bus (4) the scope place of this side.
The present invention compared with prior art, owing to take configuration of bottom land bus asymmetric and electric current asymmetric collocation method, can effectively reduce the magnetic field that electrolyzer self produces, overcome and face the influence that is listed as the slot field, therefore can make the groove internal magnetic field reach peak clipping and add flat effect, make that groove internal magnetic field gradient is littler, improved the homogeneity of magnetic fluid greatly.
