Background technology:
Current electrolysis aluminium industrial production is vertical direction with its Faradaic current trend of electrolyzer, and promptly electric current vertically enters the negative electrode that is positioned at the bottom from the anode of upper part of the electrolytic cell.The problem of Cun Zaiing has like this:
1, hundreds thousand of amperes powerful electric current will be flow through in bottom, electrolyzer molten bath, and bottom charcoal negative electrode occurs expanding and breakage under the effect of electrochemical reaction, and the life-span of electrolyzer was remained on about in the of 1800 days always.
2, electrolyzer passes through hundreds thousand of amperes powerful electric current, can produce strong-electromagnetic field.In electrolyzer, liquid aluminium is in the bottom of electrolyzer, just can enter negative electrode behind the vertical electric current process aluminium liquid layer.The electrolyzer capacity is big, into and out of the bus structure complexity of electrolyzer, the magnetic field that produces of the horizontal current magnetic field interaction that can produce with vertical current in the aluminium liquid magnetic field of different directions will appear like this, wherein, make the aluminium liquid layer fluctuation occur, cause Aluminium Electrolysis efficient to reduce.
3, for the needs of vertical conduction, middle and lower part, electrolyzer molten bath (negative electrode) has the hole for connection conductors, and this hole is the weakest link of electrolyzer liquid seepage.
The utility model content:
The purpose of this utility model is: overcome the defective of prior art, provide a kind of modern design, molten bath part without electric current, do not produce electrochemical reaction, do not need perforate, the horizontal electrolytic aluminum electrolyzer of long service life around the part of molten bath.
The purpose of this utility model is achieved through the following technical solutions: horizontal electrolytic aluminum electrolyzer is grouped into by molten bath part and electrode part.The molten bath part is made of the pot shell of steel and the flame-proof thermal insulation material that is installed in the pot shell, pot shell is the complete housing of a top opening, and enough intensity arranged, flame-proof thermal insulation material is built by laying bricks or stones in pot shell, form the bottom smooth, the molten bath of wall is arranged all around, to deposit high-temperature fluid aluminium liquid and electrolytic liquid; The electrode part partly is made up of cathode electrode part and anode electrode, effusive negative busbar composition cathode electrode part is flowed in cathode electrode, the negative electrode conducting rod that is installed in cathode electrode inside and the power supply that is connected with the negative electrode conducting rod, cathode electrode has one group at least, can be many groups according to the size of electrolyzer capacity and the requirement of groove structure; The positive bar composition anode part of anode electrode, the conductive anode rod that is installed in anode electrode inside and the inflow of the power supply that is connected with conductive anode rod stream, anode electrode has one group at least, it is corresponding one by one with cathode portion, many one group or few one group of the comparable negative electrode of quantity; The electrode part is suspended in the molten bath by supporting girder steel; Between negative electrode and the anode electrode liquid electrolyte is arranged, Faradaic current enters the side of negative electrode correspondence from anodic side level, and the aluminium liquid that electrolysis produces under action of gravity, sinks to the bottom in molten bath.
Positive beneficial effect of the present utility model:
1, the aluminium liquid layer in the utility model pot shell does not produce electromagnetic force without electric current, makes the aluminium liquid layer steady, can increase substantially current efficiency, increases primary aluminum output, saves electric energy.
