Abstract
The utility model discloses a structure of preventing magnetic field interference between a vertical disposition tank and an aluminum electrolyte tank. The middle of each electrolytic tank of the vertical disposition tank is provided with a tank bottom generatrix which passes through the tank bottom and threads out from the back of the electrolytic tank. Two to five cathode soft generatrice of the back large surface of the electrolytic tank are connected with a cathode generatrix of the back large surface. The cathode generatrix is connected with one tank bottom generatrix. The other end of the tank bottom generatrix is connected with the front end of one cathode generatrix of the front large surface of the electrolytic tank. The other end of the cathode generatrix of the front large surface of the electrolytic tank is connected with an upright post generatrix for the electrolytic tank of another downstream electrolytic tank. The utility model causes the generatrix of the back large surface part to penetrate through the electrolytic tank in the limited space in a fold line manner, and the magnetic field influence caused by the tanks in adjacent rows can be balanced. The utility model can efficiently prevent the mutual interference of the magnetic field between the vertical disposition tank and the aluminum electrolyte tank. The utility model has the advantages of simple configuration, less investment, favorable use effect and obvious effect of preventing the magnetic field interference.
Description
Technical field:
The utility model relates to a kind of structure that prevents magneticinterference between the vertical emissions groove of aluminium cell, belongs to the aluminium electrolysis slot field perturbation technique field that prevents.
Background technology:
The traditional vertical emissions groove of China's aluminium industry mostly is the self-roasting tank, and in recent years owing to environmental requirement, existing at present production self-roasting tank all is transformed into prebaked cell, and tankage is the comparatively large capacity grooved of 85 ~ 150KA by 55 ~ 70KA reorganization and expansion simultaneously.The groove row spacing of vertical emissions groove is generally about ten meters, distance closer (spacing of present most horizontally-arranged groove is more than 45 meters), and phase mutual interference in magnetic field strengthens between two emissions grooves, has a strong impact on the ordinary production of electrolyzer.Conventional compensation approach adopts bus to be compensated by the big face method of detouring in back more, and its compensation effect can not satisfy the requirement of electrolyzer Magnetic Field Design to jumbo grooved poor effect, can cause electrolyzer stability to wreck, and brings very big harm to production operation.Therefore, existingly prevent that the technology of magneticinterference between the vertical emissions groove of aluminium cell from still being not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of structure that simple, less investment, effect prevent magneticinterference between the vertical emissions groove of aluminium cell preferably that disposes, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it all is equipped with the bottom land bus (3) that passes bottom land and pass later from electrolyzer in each electrolyzer of vertical emissions groove, 2～5 cathode soft bus (1) of big face are connected with the negative busbar (2) of the big face in back behind its electrolyzer, and negative busbar (2) is connected with 1 bottom land bus (3), the other end of bottom land bus (3) is connected with the front end of the preceding big face negative busbar (4) of electrolyzer, and the other end of big face negative busbar (4) is connected with the groove riser bus bar (5) of another electrolyzer of downstream before the electrolyzer; Be connected to welding between each bus.
Owing to adopted technique scheme, under the voltage condition such as the utility model utilization, the relation principle that electric current and resistance (bus distance) are inversely proportional to, the big face portion bus in back is passed through electrolyzer in the broken line mode in limited space, with the influence of magnetic field that the adjacent row groove of balance produces, it can prevent the phase mutual interference in magnetic field between the vertical emissions groove of aluminium cell effectively.Adopt the utility model, can not only effectively weaken the influence of adjacent row groove, make that full slot field is evenly distributed, gradient is little, reach the effect of " peak clipping, add paddy ", and can effectively solve the vertical emissions groove magnetic field problem of comparatively large capacity.This busbar arrangement of wearing slot type bottom land bus-bar collocation of the utility model makes electrolyzer obtain rational groove internal magnetic field distribution and stable melt flow field, it can guarantee the stable and higher current efficiency of electrolyzer production process, can well finish design and production demand, fully satisfy the electrolyzer durability requirements.Through evidence, the utility model and the tens of branch couplings of full groove cathode and anode group can reach best electricity, magnetic, the fluid characteristics relation of matching.The utility model has obtained in the preferable groove dynamically electromagnetic hydroimechanics operating performance after test on vertical row's aluminium cells such as 120KA level, 150KA level is used, reached that full slot field is evenly distributed, electrolyzer production is steady.Therefore the utility model compared with prior art the utlity model has that configuration is simple, less investment, result of use is better and the tangible advantage of anti-magnetic field interference effect.

Embodiment:
Embodiment of the present utility model: in each electrolyzer of existing vertical emissions groove, all install the bottom land bus (3) that passes bottom land and pass later from electrolyzer, 2～5 cathode soft bus (1) of big face behind its electrolyzer and the negative busbar (2) of back big face are welded to connect, and this negative busbar (2) and 1 bottom land bus (3) are welded to connect, the front end of big face negative busbar (4) before the other end of bottom land bus (3) and the electrolyzer is welded to connect, the groove riser bus bar (5) of the other end of big face negative busbar (4) before this electrolyzer and another electrolyzer of downstream is welded to connect.
