Description
Technical field
The present invention relates to a kind of carbon anode, in particular to the flat charcoal bowl anode of a kind of aluminium.
Background technique
Carbon anode used for aluminium electrolysis refers to the carbonaceous electrodes being connected in aluminium cell with positive pole, is the important of aluminium cell
Component part.Prebaked anode in aluminium cell is made of multiple anode block groups, and each anode block group is by the wide 700- of 1-2 block
The part such as anode block, anode rod and steel pawl of 900mm, long 1400-1700mm, high 500-600mm forms.Aluminium cathode sun
Pole is used for the anode of aluminium cell, electric current is imported electrolytic cell, and participate in electrochemical reaction.Carbon anode day is flat in aluminium electrolysis process
2cm or so is consumed, needs to regularly replace new anode block (prebaked anode), aluminium cell is made to keep running well.
Electrolysis is high energy-consuming industry, as primary aluminum caused by the high enterprise of current electricity price and excess capacity is on the low side, such as
What effectively realizes that energy-saving is entire industry problem of interest.The contact drop for reducing each position of anode unit is electrolysis production
Reduce the effective way of energy consumption.
After ferrophosphorus water is cast in charcoal bowl, the molten iron on top is exposed to because contacting with atmosphere, heat dissipation is very fast, is first frozen into
Type, lower part molten iron successively slow solidification, bottom it is final solidified.Convergent force is generated when bottom molten steel solidification, will pull
The top ferrophosphorus of solidification expands outwardly, and last ferrophosphorus and steel pawl will form tiny gap (as shown in Figure 1).Because ferrophosphorus bottom is cold
But the gap for causing side ferrophosphorus to open is shunk, although temperature raising can reset after upper slot, transport, dress pole before upper slot are made
Dust can enter in gap in industry, although resetting, dust can reduce electric conductivity, and contact drop increases 10-15mv.
It is accordingly required in particular to which a kind of flat charcoal bowl anode of aluminium, above-mentioned existing to solve the problems, such as.
Summary of the invention
The purpose of the present invention is to provide a kind of flat charcoal bowl anodes of aluminium not to change in view of the deficiencies of the prior art
Under the premise of electrolysis production technique and influence anode use, by removing carbon removal bowl bottom boss, reach reduction iron-carbon contact pressure
Drop, to reduce aluminum electrolysis power consumption.
Technical problem solved by the invention can be realized using following technical scheme:
The flat charcoal bowl anode of a kind of aluminium, which is characterized in that it includes several charcoal bowl portions being arranged on anode, the charcoal
Helicla flute is provided on the inside of bowl portion, the top of the helicla flute is concordant with the top in charcoal bowl portion, the bottom of the helicla flute
The bottom in portion and charcoal bowl portion is located in same level.
In one embodiment of the invention, charcoal bowl cover is additionally provided in charcoal bowl portion.
Further, the through-hole for allowing steel pawl to pass through is provided in the charcoal bowl cover.
In one embodiment of the invention, the internal diameter in charcoal bowl portion is slightly larger than the outer diameter of steel pawl.
In one embodiment of the invention, the helicla flute is interconnected and fixed by ferrophosphorus and steel pawl.
The flat charcoal bowl anode of aluminium of the invention by removing carbon removal bowl bottom boss, reduces anode compared with prior art
With the contact drop of steel pawl, ferrophosphorus bottom thickness is reduced, convenient for the pressure-off of ferrophosphorus；When using on electrolytic cell, anode does not take off
Pole reveals the exact details, changes pawl failure, can substantially reduce aluminum electrolysis cost, achieve the object of the present invention.
The features of the present invention sees the detailed description of the drawings of the present case and following preferable embodiment and obtains clearly
Solution.
