A kind of bianode linker structure
Technical field
The utility model relates to the structure of a kind of double anode linker of aluminium cell.
Background technology
Along with the capacity of aluminium cell continues to increase, if only mount an anode carbon block by an anode rod in the past, under the situation that anode carbon block can not be done too greatly, certainly will need to increase the anode group number on the electrolyzer, cause anode group number to increase with the continuous increase of electrolyzer capacity, the physical dimension of electrolyzer also continues to increase thereupon.Therefore, the double anode structure occurred, this helps improving the yield per unit of electrolyzer, has also reduced replacing anodic workload.
Existing double anode structure, every anode steel jaw is 4 pawls, press designed charcoal piece of 4 pawl anodes and the syndeton between the anode rod, caused the electrolytical difficulty of being stained with band on the cleaning anode scrap, the ionogen that is position between the steel pawl is difficult to cleaning, carry too much electrolytical anode scrap secretly after entering the charcoal piece pressure-off operation of anode assembling procedure, contained ionogen composition significantly increases in the anode scrap, and this part anode scrap is still as one of raw material of producing new anode carbon block, with having a strong impact on the reasonable component of anode carbon block, reduced the anode quality.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of bianode linker structure is provided, and it makes the ionogen at position between the steel pawl be convenient to clear up, help guaranteeing the reasonable component of anode carbon block, improves the anode quality.
In order to solve the problems of the technologies described above, the utility model is achieved in that it adopts 3 pawl anode carbon blocks to make double anode, linker in the anode rod lower end, make and lack horizontal M shape, promptly compare with conventional art, linker is not provided with the steel crossbeam along its length above anode carbon block, anode rod vertically welds in the central position of linker, whole linker is a cast steel manufacturing, 6 steel pawls of linker are corresponding with totally 6 steel pawl grooves of 2 anode carbon blocks, use the phosphorus pig iron the steel claw portion of linker and 2 anode carbon block Joints.
Advantage of the present utility model and effect are: the structure of this linker, and not along the crossbeam of anode carbon block length direction, so will make things convenient for manyly during the ionogen on the cleaning anode scrap.What linker mounted is two 3 pawl anodes, and the structure of this linker makes the distribution of electric current on anode carbon block more even.Structure-integrated casting forms, and makes processing and manufacturing easier, quick, is easy to guarantee its consistence and quality.
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

Fig. 2 is a linker schematic perspective view of the present utility model.
Fig. 3 adopts anode group synoptic diagram of the present utility model.
Fig. 4 adopts anode group vertical view of the present utility model.
Embodiment
Be connected with linker 1 of the present utility model between anode rod 5 anode carbon block 2 with three steel pawl grooves identical, form a bianode anode group with two specifications.
The concrete structure of linker 1 is: three steel pawls are set on every anode carbon block 2, totally six, linker 1 is not provided with the steel crossbeam along its length above anode carbon block 2, anode rod 5 vertically welds in the central position of linker 1, whole linker 1 is that cast steel material is made once-forming, and linker 1 is for lacking horizontal M shape.
Being connected between linker 1 and the aluminum anode rod 5, adopt aluminium-steel explosive welding, the upper end 4 of the lower end of guide rod and linker 1 will make the smooth and no-sundries of end face of its weld through processing before explosive welding.Promptly can enter the anode assembling procedure after welding, finish fixedlying connected of linker 1 and anode carbon block 2 in this operation.
On each piece three-jaw anode carbon block 2, there are three in order to three circular grooves of steel pawl to be installed, six steel pawls on the linker are after graphiting and drying, be inserted in the corresponding circle connected in star of respective anode charcoal piece 2, the casting phosphorus pig iron 3 in steel pawl and groove that the charcoal piece contacts realizes that iron-carbon connects then.The anode group that assembles just can be sent on the electrolyzer and use.
