Charcoal bowl is used for installing anode joint, and casts in charcoal bowl with the phosphorus pig iron by anode joint, anode joint and aluminum
Conducting rod is connected by aluminum steel blast weldering, then makes aluminum conducting rod and anode carbon block compact siro spinning technology, forms anode
Carbon block group.During Aluminum Electrolysis Production, the oxygen that anode carbon block can decompose out because of itself and alumina eltrolysis
At high temperature constantly reaction discharges carbon dioxide and constantly consumes, and therefore anode carbon block needs periodic replacement, changes
The carbon block of rear remnants is commonly called as anode anode scrap.At present this production technology is primarily present following shortcoming, and 1) more renew
Anode carbon block is in normal-temperature, could conduct electricity, therefore change in electrolysis bath to be put into after preheating in about 24 hours
Anode carbon block can make heat loss increase, and the biggest to the stable working impact of electrolysis bath during change poles；2) anode
Replacing can form periodically impact to aluminum electrolysis, destroys energy and the material balance of electrolysis bath, impact
Current efficiency, increases power consumption rate；3) in order to be separated with anode anode scrap by anode joint, need to water the phosphorus pig iron
Charcoal bowl at casting is broken into pieces, makes anode anode scrap come off to realize separating from anode joint, and this process is not only time-consuming,

Value reaches the anode carbon block of 10,000,000,000 yuan；4) having the porosity of 14%～18% because of anode carbon block itself, therefore anode is residual
The substantial amounts of electrolyte of pole internal adsorption, the main component of electrolyte is fluoride salt, containing the sun of a large amount of fluoride salts
Pole anode scrap environmental pollution is extremely serious；5) when just anode joint casts in charcoal bowl, in order to reduce sun
Pole anode scrap waste, it is necessary to as far as possible anode anode scrap is burnt thin, on anode carbon block end of lifetime, the top of anode carbon block
Face is sufficiently close to electrolyte level face, and by magnetic field and airflow influence, bath surface constantly has strong wave
Producing, in actual production process, anode joint is often corroded by electrolyte, and the ferrum element of anode joint dissolves in
In electrolyte, enter aluminium ingot immediately, affect quality of finished；Anode joint generally uses the life-span at about 3 years,
This also makes production cost increase accordingly, and at anode carbon block end of lifetime, the thinnest anode anode scrap thickness, must
So bringing charcoal pole conduction inequality, and then cause electrolysis bath fluctuation of operating conditions, power consumption increases.

Separate the process breaking anode anode scrap into pieces that needs not move through, but directly by load-bearing conducting beam from second layer dislocation lap joint
Multi-functional hole slot is extracted out, the most not only saves the time, and makes labor intensity reduction, efficiency improve.
The present invention connects two pieces of anode carbon blocks (being called for short lastblock and next block) by carbon block gluing layer, produces
Cheng Zhong, next block carries out electrolysis production, lastblock along with produce in temperature be raised through carbon block gluing layer glue
It is connected together.Must withdraw from when next block is depleted to load-bearing conducting beam, not so load-bearing conducting beam will be by electrolyte
During erosion, solid for connection cross-arm is connected the load-bearing conducting beam of through lastblock, and makes the solid cross-arm of connection depart from next block
On load-bearing conducting beam, the little bus of conduction on next block carbon block load-bearing conducting beam is transferred to lastblock one by one
The corresponding site of load-bearing conducting beam, after the solid cross-arm of connection, little bus all connect, extracts the load-bearing in next block out
Conducting beam, (this process is called for short and connects conversion).Now, lastblock merges into one with the remainder of next block
Individual entirety (this entirety is called for short intermediate mass), it is raw that switching process uses intermediate mass to carry out electrolysis after neutralizing the most continuously
Produce, and the bonding one piece of anode carbon block of superposition on intermediate mass again, and progressively decline, continuous consumption, with this
Realize producing continuously；By this structure, the production process of next block is also the slow warm of lastblock,
Warm does not touch electrolyte, adds pole the most just unlike change poles, adds pole and does not produce strong heat, surge,
Make electrolysis production more steady.For preventing from surprisingly falling the generation of block (falling pole) major accident, for guaranteeing gluing layer
Temperature can reach 500～700 DEG C, proposes again auxiliary hook, and principle is as follows: when lower section anode carbon block scaling loss
Time, first with auxiliary hook, the load-bearing conducting beam of lower anode carbon block and top is linked together so that cohere
Layer can continue to sinter in the case of not by pulling force, and anode carbon block continues to cohere leafing after the big layer of scaling loss one
Electrolyte is the nearest, and temperature is the highest, the most firm.By the time gluing layer bond strength can reliably be able to lift remaining sun
Removing auxiliary hook during the carbon block of pole again, the most remaining carbon block is more frivolous than carbon block when just removing through beam to be permitted
Many.At this moment remove auxiliary hook, both can ensure whenever gluing layer has enough mechanical strengths with reliable
Property can not ensure the major accident of block (falling pole), also can guarantee that through beam and hook will not be electric simultaneously
Solution matter corrodes.

Take, and it also avoid the pollution to environment of the anode anode scrap of a large amount of fluoride salt of absorption person.The present invention in addition
Aborning, changed by connection, it is to avoid load-bearing conducting beam is corroded by electrolyte, compared with anode steel claw,
There is not the problem corroded by electrolyte in load-bearing conducting beam, it is therefore prevented that the first procatarxis in load-bearing conducting beam corrode into
Enter electrolyte and affect aluminum water quality.The present invention does not haves the situation that anode anode scrap thickness is the thinnest aborning,
Thus avoid because charcoal pole conduction inequality causes electrolysis bath fluctuation of operating conditions and then the problem increasing power consumption.
Existing pre-baked anode carbon blocks is when electrolysis production, and particularly volume arrives greatly and is equivalent to the pre-of soberberg anode
Roasting anode carbon block, often can form " enclosed mass " in the position in the middle part of its palm bottom surface, and " enclosed mass " can cause local
Short circuit current, causes current efficiency substantially to reduce；The formation of " enclosed mass " is primarily due to be positioned at anode carbon block
Position in the middle part of bottom surface from the edge of anode carbon block too far, makes bubble be difficult to discharge, thus forms bigger gas
