The utility model relates to a kind of aluminium cell, relates in particular to a kind of strength of current at 150kA and the aluminium cell more than the 150kA.
Background technology
Being used for the industrial Hall-Heroult electrolyzer of aluminium at present uses the charcoal piece of carbon anode and surface level as negative electrode, pass through electrolysis of aluminum oxide for producing aluminum, ionogen mainly is made up of sodium aluminum fluoride and alumina melt, is dissolved in wherein aluminum fluoride and other fluoride salt in addition in addition.The aluminium that electrolysis is separated out is accumulated in bottom land charcoal piece negative electrode top, forms the aluminium liquid layer, and as the part of negative electrode.
Existing Hall-Heroult aluminium cell, all having a general problem according to size and electrolysis process different is exactly that electric energy efficiency is lower, and generally between 45～50%, remaining electric energy all is converted into heat energy dissipation and has fallen.The pole span of existing aluminium cell generally all about 4.5cm, causes the low major cause of electric energy efficiency just to be that existing common prebaked cell has big pole span.
Electric energy efficiency is hanged down and has been caused the meaningless consumption of huge electric energy on the industrial cell, and the energy-saving and cost-reducing means of aluminium cell have two kinds, and a kind of is to improve current efficiency, and another kind is exactly to reduce pole span, reduces bath voltage.And existing electrolyzer, current efficiency is mostly below 95%, and the space of improving current efficiency is limited.Aluminum current electrolyzer pole span generally about 4.5cm, is given the energy-saving and cost-reducing very big space that provides, but because the restriction of traditional this body structure of electrolyzer reduces pole span, it is unstable that electrolyzer will become, and loses current efficiency, is difficult to reach purpose of energy saving.
The utility model content
Technical problem to be solved in the utility model is: a kind of aluminium cell is provided, and purpose is to improve the electric energy efficiency of aluminium cell, reduces the interpolar pressure drop, reduces the influence of magnetic field to Aluminium Electrolysis stability.
In order to solve the problems of the technologies described above, the utility model is achieved in that aluminium cell, it comprises pot shell, liner and superstructure, be provided with cathode block in the liner, superstructure is provided with anode block, wherein is provided with curb between every group of cathode block of liner, the liner upper middle position is provided with remittance aluminium ditch, the aluminium side that goes out of the end electrolyzer of liner is provided with the Aluminum storage groove, and an end of remittance aluminium ditch is connected with the Aluminum storage groove, is provided with blanking point between anode block.
Described electrolyzer longitudinal cenlerline is designed to notch cuttype, and the ladder number is 2～5.
The break joint of described blanking point place anode block is 180～250mm.
Stick with paste the curb that is bundled into 2～10% gradients between described adjacent cathode block.
The upper surface of described anode block is TiB
2Composite bed, the thickness of composite bed are 10～50mm.
Described blanking point is 2～8, and blanking point is arranged on the position away from the electrolyzer longitudinal cenlerline.
Characteristics of the present utility model and effect are as follows:
Do not preserve aluminium liquid between the anode block of the aluminium cell of the utility model structure and the cathode block, make pole span from traditional electrolysis slot number apart from by dropping to 2.5～3cm about 4.5cm, stick with paste between cathode block and be bundled into constant slope, the aluminium of being convenient to the electrolysis generation in time imports middle groove, the electrolyzer longitudinal cenlerline is designed to stair-stepping groove, be convenient to the Aluminum storage groove that aluminium liquid flows into electrolyzer one side, the Aluminum storage groove is used to store the aluminium that electrolysis generates, electrolyzer adopts the multiple spot blanking, and blanking point is away from the electrolyzer longitudinal cenlerline.
The utility model has improved utilization rate of electrical owing to adopt said structure to reduce pole span, has realized that simultaneously the aluminium cell interpolar does not have aluminium liquid electrolysis production, greatly reduces the influence of magnetic field to Aluminium Electrolysis stability.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is elaborated, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1-Figure 3, strength of current is between 150kA～200kA, the structure of aluminium cell is as follows: it is by pot shell 7, liner 8 and superstructure 9 constitute, every group of 2 of cathode block is provided with curb 6, liner 8 upper middle position are provided with remittance aluminium ditch 3, the aluminium side that goes out of the end electrolyzer of liner 8 is provided with Aluminum storage groove 4, one end of remittance aluminium ditch 3 is connected with Aluminum storage groove 4, be provided with 20 groups of cathode blocks in the liner 8, superstructure 7 is provided with 18 groups of anode blocks, the quantity of anode block 1 and cathode block 2 can carry out determining that rationally this does not do detailed description for known technology according to factors such as strength of current; Be provided with 4 blanking points 51 of adjacent anode carbon piece, blanking point 5 is away from the electrolyzer longitudinal cenlerline, and the break joint of blanking point 4 place's anode blocks 1 is 180～250mm; 2 pastes of the adjacent cathode block of liner are bundled into the curb 6 of 2-10% gradient, are convenient to aluminium liquid and flow into remittance aluminium ditch 3; The electrolyzer longitudinal cenlerline is designed to notch cuttype, and the several size variation according to the electrolyzer capacity of ladder are generally 2～5, is convenient to aluminium liquid and compiles to end Aluminum storage groove 4; The product aluminium amount that the capacity of Aluminum storage groove 4 satisfies electrolyzer half a day gets final product; The upper surface of anode block 2 is TiB
2Composite bed, the thickness of composite bed are 10～50mm; Because the aluminium liquid that electrolysis produces is sent into Aluminum storage groove 4 timely, has realized that interpolar does not have the production of aluminium liquid, therefore eliminated the influence of magnetic field to electrolysis production stability, pole span can be produced at 2.5～3cm, has improved electric energy efficiency.
The quantity of above-mentioned blanking point 5 can be carried out rationally determining, is generally 2～8 according to the size variation of electrolyzer capacity.
