Description
Technical field
The utility model relates to the anode carbon block technical field of structures in aluminum electrolysis.
Background technique
In aluminium electroloysis industry, anode carbon block, mainly using stone tar, pitch coke as aggregate, is viscous with coal tar pitch using material
Agent is tied, under certain process conditions, is squeezed by anode mold or vibrating forming.According to production requirement and process characteristic, can make
Make a plurality of types of anode carbon blocks, different type anode carbon block is primary concern is that anode carbon block quality, electrolytic cell production capacity
Three aspects are matched with production technology, the current density of anode carbon block is generally in 0.68-0.92a/cm2, service life is general
At 28-35 days.Anode carbon block appearance mainly based on cuboid, is partially formed certain thickness boss, makes 3-5 circular groove
Charcoal bowl, anode steel claw are placed in the charcoal bowl of anode carbon block, are cast and are fixed using phosphorus pig iron casting formula, steel pawl head and aluminium conducting rod
It is exploded by aluminum steel and welds connection, conductive anode rod and anode carbon block is allowed to be linked together, form anode carbon block group.
The requirements at the higher level that production cost control is proposed with enterprise, it is necessary to further decrease a ton aluminium charcoal consumption cost.Anode
Carbon block part scaling loss after using some cycles, needs timing to replace, and can have small part and anode is not used, be commonly called as " anode scrap ",
After processing, the assembling of steel pawl head and the recycling of aluminium conducting rod for next piece of new anode carbon block group, anode scrap recycling is sold, but sun
Pole carbon block is sold from buying in use to anode scrap, although being all identical material, the two price differs too big, causes production cost
Waste, the weight of carbon block accounts for the 10%-14% of monolith anode carbon block in anode scrap, and proportion is quite big, correctly to anode into
Row improves, and allows the effective of anode carbon block to reach higher service efficiency using weight, can achieve the mesh for reducing anode carbon block hair consumption
's.
Its planform of existing anode carbon block is as shown in FIG. 1 to 3, including carbon block main body A, boss B and charcoal bowl C, charcoal
Block main body is cuboid, and the mutual corner D in four sides is right angle, four four corner E between side and top surface with
And four four corner F between side and bottom surface are also right angle, the distance F of bottom edge to the carbon block body rim of boss is only
The height G of 30mm, boss are only 70mm, in use, this anode construction there are the problem of mainly have: first is that corner is
Right angle easily causes anode to lose under the washing away of electrolyte and right angle anodic oxidation situation, causes anode carbon consumption to increase, electric current
Efficiency reduces；Second is that the height of boss only has 70mm, the height of charcoal block main body is in 565mm, and according to anode consumption, there are anodes
Extend that a period is not enough, do not extend a period remains blocked up situation again, causes the waste that carbon block is excessive；Third is that at present
The boss structure of anode carbon block does not study the conductive feature of anode, using trapezium structure, boss is caused to occupy excessive carbon block weight
Amount.
Summary of the invention
Utility model aims to solve problems of the existing technology, and anode loss and oxygen can be reduced by providing one kind
Change, and under determining anodic cycle, can reduce anode carbon block boss quality, so that anode scrap weight is reduced, to reduce anode
The aluminum electrolysis anode carbon block of charcoal block cost and ton aluminium anodes charcoal consumption.
The technical solution that the utility model is taken is as follows:
A kind of aluminum electrolysis anode carbon block, including cuboid charcoal block main body, be located at cuboid carbon block body top and with it is rectangular
The integrally formed trapezoid boss of body charcoal block main body, four on the trapezoid boss surface spill charcoal bowls uniformly arranged；It is described
Mutual corner i.e. the first corner in four sides of charcoal block main body be arc transition angle, four between side and top surface four
A corner i.e. the second corner is right angle, and a corner, that is, third corner between short side and bottom surface is right angle, excess-three
Corner i.e. the 4th corner between side and bottom surface is arc transition angle；Mutually join on four inclined-planes of the trapezoid boss
Corner beveling has apex angle inverted triangle section directed downwardly；It is evenly equipped on charcoal bowl side wall from upper edge to what rotary table bottom extended and inclines
Oblique groove.
Charcoal bowl concave structure described in the utility model is the truncated cone-shaped charcoal bowl to sink, and rotary table top bore is greater than lower ports
Diameter.A length of 1550mm of the cuboid charcoal block main body, width 660mm, a height of 540mm, a height of 100mm of trapezoid boss, entirely
Always a height of 640mm, a length of 1250mm in trapezoid boss top, a length of 1350mm in bottom, the width of top and bottom are respectively carbon block
330mm and 520mm；The bottom edge of inverted triangle section is respectively to shear 100mm length along trapezoid boss top surface quadrangle adjacent edge to be formed；Institute
The arc radius for stating the first corner and the 4th corner is 50mm.The charcoal bowl upper radius be 90mm, lower part 85mm, it is described
The tilt angle of inclined groove is 75 °.
The utility model has the advantage that
1, it analyzes after study, it is determined that the trapezoid boss top of anode carbon block is minimum on the influence of anode conducting performance, because
This, is mitered into apex angle inverted triangle section directed downwardly for the corner that four inclined-planes of trapezoid boss mutually join, alleviates anode
Carbon quality, in the case where extending one period of anode, anode scrap thickness can guarantee not to be occurred filling bottom and changes pawl in charcoal bowl bottom
Phenomenon does not generate impurity interference to primary aluminum quality, meets production requirement, and anode scrap weight also reduces, and reduces a ton aluminium anodes charcoal consumption；
2, due to place insulation material on carbon block top in production, anodic oxidation and insulation effect, the utility model are prevented
The length of two short seamed edges of carbon block body top to boss is increased, makes carbon block top material be not easy to fall, can be completely covered
Anode prevents anode upper oxide and enhancing insulation effect, reduces ton aluminium anodes charcoal consumption；
3, three seamed edges of carbon block bottom part body are changed to arc chord angle, and the seamed edge of side four is changed to arc chord angle, so that when in use
Current density is evenly distributed, and side can reduce the anodic oxidation of corner, and bottom avoids arris carbon block due to washing away for electrolyte
It is a large amount of scaling-off, reduce ton aluminium anodes charcoal consumption.
