Description
Technical field
The utility model belongs to field of metallurgical equipment, specifically a kind of aluminum electrolyzing cell used prebaked anodes of 400KA.
Background technology
As aluminum electrolysis industry production capacity is expanded, cost, energy consumption, the pressure of environmental protection gradually increase, and electrolysis aluminum production enterprises are more
Filling is again to power-saving technology, the development and breakthrough of equipment.By the improvement to electrolytic cell prebaked anode structure and shape, energy is reduced
Consumption and supplies consumption have turned into the important thinking of industry energy-saving drop originally.
The structure and shape of prebaked anode and anode drop, radiation loss and uniformity, supplies consumption etc. have relation.Mesh
Preceding prebaked anode shape, the intersecting rib in each face is mostly right angle, causes the uneven of CURRENT DISTRIBUTION to a certain extent, is radiated
Big and not uniform enough, anode gross weight is big, and anode carbon block consumption is high.
How by the optimization design of anode construction, it is that aluminium electroloysis industry is inquired into always to reduce anode drop and carbon block consumption
One of the problem of.
Utility model content
The purpose of this utility model is the provision of a kind of aluminum electrolyzing cell used prebaked anodes of 400KA, and it is pre- to reduce aluminium cell
Anode drop is roasted, extends anode service life.
Technical scheme provided by the utility model is：
A kind of aluminum electrolyzing cell used prebaked anodes of 400KA, by be fixedly connected sequentially from bottom to up the anode carbon block that is integrated with
Trapezoidal frustum, anode steel claw three parts composition, anode carbon block is cuboid, and the bottom surface of its upper bottom surface and trapezoidal frustum is fixed
Connect as one, trapezoidal frustum upper bottom surface is poured by charcoal bowl with anode steel claw by the phosphorus pig iron to be connected to one；Anode
The incline that carbon block and trapezoidal frustum each intersect between four sides is for arc chord angle or 45 degree of chamferings respectively.
The technical solution of the utility model, by the angle of cut of four sides of existing aluminum electrolyzing cell used prebaked anode and bottom surface by
Traditional 90 degree are changed to arc chord angle or 45 degree of angles, revolutionize the definitely smooth old theory of prebaked anode bottom.
Also included optimization or/and improvement of the present utility model have：
One of preferred scheme, the top rib that the anode carbon block intersects with respective four sides of trapezoidal frustum with top surface are distinguished
For arc chord angle or 45 degree of chamferings.
The two of preferred scheme, four sides and the basal edge that its bottom surface is intersected of the anode carbon block be respectively arc chord angle or
45 degree of chamferings.
The three of preferred scheme, four sides of the trapezoidal frustum and the top surface intersection of anode carbon block are respectively arc chord angle
Transition.
Implementing the beneficial effect of technical solutions of the utility model is：
CURRENT DISTRIBUTION is optimized, the heating power consumption of prebaked anode in a cell is reduced, is used in prebaked anode
In the case that cycle is constant, anode gross weight is reduced, so as to reduce a ton aluminium charcoal consumption.
Describe the technical solution of the utility model in detail with reference to the accompanying drawings and examples.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；

Fixed.
Embodiment 1：
As shown in figure 1, a kind of aluminum electrolyzing cell used prebaked anodes of 400KA, by being fixedly connected sequentially what is be integrated from bottom to up
Anode carbon block（1）With trapezoidal frustum（2）, anode steel claw（3）Three parts form, anode carbon block（1）For cuboid, its upper bottom surface
With trapezoidal frustum（2）Bottom surface be connected to one, trapezoidal frustum（2）Upper bottom surface passes through charcoal bowl（4）With anode steel claw（3）
Poured and be connected to one by the phosphorus pig iron；Anode carbon block（1）With trapezoidal frustum（2）The side intersected between respective four sides
Rib（5）It is for arc chord angle or 45 degree of chamferings respectively.
Embodiment 2：
Optimization provided by the utility model or/and improvement are further described with reference to embodiment 1 and accompanying drawing 1：
The anode carbon block（1）With trapezoidal frustum（2）The top rib that intersects with top surface of respective four sides（6）It is respectively round
Arc angle.
The anode carbon block（1）The basal edge that intersects with its bottom surface of four sides（7）Respectively arc chord angle.
The trapezoidal frustum（2）Four sides and anode carbon block（1）Top surface intersection be respectively arc chord angle transition.
In the present embodiment, aluminium charcoal consumption per ton reduces 7kg, and based on 2800 yuan/ton of carbon block price, ton aluminium reduces cost 19.6
Member, for 200,000 tons of small-sized aluminium electroloysis enterprise, you can cost-effective 3,920,000 yuan, the cost that medium-and-large-sized aluminium electroloysis enterprise saves
It is then more considerable.
