Abstract
The invention relates to an electric input busbar configuration structure for an aluminum electrolytic cell, in particular to a non-symmetrical six-point electric input busbar configuration structure for a large-scale aluminum electrolytic cell, which comprises an electrolytic tank, wherein the electric input side and the electric output side of the electrolytic tank are provided with cathodic soft buses with the same quantity respectively; and the cathodic soft buses are connected with risers through negative busbars. The structure has the advantages that: compared with the prior art, the structure ensures that magnetic fields produced by the current of a groove, adjacent grooves and adjacent columns of groove busbars in a melt are canceled with each other due to the adopted electric input configuration of the non-symmetrical six risers and non-symmetrical left-right end bypass current; the total magnetic field in the magnet is smaller and has even distribution, and the magnetofluid stability is ensured.
Description
Technical field
The present invention relates to a kind of aluminium cell and advance goddess of lightning's line configuration structure, relate in particular to asymmetric 6 of a kind of large-scale aluminum electrolytic cell and advance goddess of lightning's line configuration structure.
Background technology
The tankage of modern prebaked cell for aluminum-reduction trends towards large scale development, and the electric current that its concrete sign is an electrolyzer progressively increases.Magnetic field in the electrolyzer in the melt is subjected to the influence of cell current very big.If the bus configuration mode of large scale electrolytic cell continues to continue to use the busbar arrangement of small-sized electrolyzer, because the rising in the magnetic field that this groove, adjacent slot and adjacent row groove cause will cause the interface of melt in the groove to take place than great fluctuation process the current efficiency of electrolyzer to be reduced greatly.
Summary of the invention
The invention provides asymmetric 6 of a kind of large-scale aluminum electrolytic cell and advance goddess of lightning's line configuration structure for solving the problems of the technologies described above, purpose is the vertical magnetic field and the transverse horizontal magnetic field that can effectively reduce melt in the groove, realize the uniform distribution in magnetic field and the steady running of aluminium cell, improve the current efficiency of electrolyzer.
Advance goddess of lightning's line configuration structure for reaching asymmetric 6 of a kind of large-scale aluminum electrolytic cell of above-mentioned purpose the present invention, comprise electrolyzer, be respectively equipped with the cathode soft bus of identical radical at the electricity input side of electrolyzer and electricity output side, these cathode soft bus are connected with riser bus bar by negative electrode.
Described riser bus bar is the six roots of sensation.
The magnitude of current of described left and right pillar bus is a symmetrical arrangements, and the magnitude of current of the right two root post buses is greater than the magnitude of current of the left side two root post buses.
The magnitude of current of the four root post buses of described the right and left is greater than the magnitude of current of middle two root post buses.
The current ratio of the described bus that detours from the left end end that left end two root post buses are connected with negative busbar is big with the electric current of the bus that detours from the right-hand member end that right-hand member two root post buses are connected with negative busbar.
The electric current of described two bottom land buses that middle two root post buses are connected with negative busbar at the bottom of the medial launder equates.
Advantageous effect of the present invention: compare with prior art, the present invention since the asymmetrical six roots of sensation riser bus bar that adopts advance the electricity configuration and asymmetric about hold bypass current, cancel out each other in the magnetic field that makes the electric current of this groove, adjacent slot and adjacent row groove bus produce in melt, magnetic field total in the melt is less, and be evenly distributed, guaranteed good hydromagnetic stability.
