Abstract
The invention discloses an anode carbon block connecting structure and method. The anode carbon block connecting structure is characterized by comprising a carbon block body (1), fixing protruding heads (3) are arranged on the top of the carbon block body (1), fixing grooves (4) are formed in the bottom of the carbon block body (1), and the fixing protruding heads (3) and the fixing grooves (4) are used for connecting an upper anode carbon block, a lower anode carbon block and an anode carbon block. After the new anode carbon block is adopted for replacement, the new anode carbon block is still fixed and borne by a steel claw on the top, and the old anode carbon block is connected with the new anode carbon block through the fixing protruding heads and the fixing grooves. Due to the fact that most of the old anode carbon block is burnt out and most of the old anode carbon block is immersed in an electrolyte of an electrolysis cell and the electrolyte has buoyancy on the anode carbon block, the connecting force needed by the old anode carbon block is little at the moment, and the oil anode carbon block can be connected firmly through a sintering or pouring manner between the fixing protruding heads and the fixing grooves.
Description
Technical field
The present invention relates to the anode carbon block in a kind of Aluminum Electrolysis Production field, particularly a kind of anode carbon block attachment structure and method.
Background technology
Modern Aluminium Industry, commonly used prebaked anode produces electrolytic aluminium.It is provided with at anode carbon block upper surface

Circular groove, be commonly called as charcoal bowl, when anode assembling charcoal bowl be used for anode joint is installed, and with the phosphorus pig iron, anode joint is cast in charcoal bowl, anode joint and aluminum conducting rod are connected by aluminum steel blast weldering, then make aluminum conducting rod and anode carbon block compact siro spinning technology, form anode carbon block group.During Aluminum Electrolysis Production, anode carbon block can the most constantly react release carbon dioxide because of oxygen that itself and alumina eltrolysis decompose out and constantly consume, and therefore anode carbon block needs periodic replacement, and carbon block remaining after replacing is commonly called as anode anode scrap.This production technology is primarily present following shortcoming at present,
1
) anode carbon block that more renews is in normal-temperature, through about in electrolysis bath to be put into
24
Could conduct electricity after hour preheating, therefore replacing anode carbon block can make heat loss increase, and the biggest to the impact of the stable working of electrolysis bath during change poles；
2
) replacing of anode can form periodically impact to aluminum electrolysis, destroy energy and the material balance of electrolysis bath, affect current efficiency, increase power consumption rate；
3
) in order to be separated with anode anode scrap by anode joint, need the charcoal bowl at by phosphorus pig iron casting to break into pieces, make anode anode scrap come off to realize separating from anode joint, this process is not only time-consuming, and labor strength is big, efficiency is low；

Porosity, the therefore substantial amounts of electrolyte of anode anode scrap internal adsorption, the main component of electrolyte is fluoride salt, the anode anode scrap environmental pollution containing a large amount of fluoride salts is extremely serious；
5
) when just anode joint casts in charcoal bowl, in order to reduce the waste of anode anode scrap, it is necessary to anode anode scrap is burnt thin, at anode carbon block end of lifetime as far as possible, the end face of anode carbon block is sufficiently close to electrolyte level face, by magnetic field and airflow influence, bath surface constantly has strong wave to produce, in actual production process, anode joint is often corroded by electrolyte, the ferrum element of anode joint dissolves in electrolyte, enters aluminium ingot immediately, affects quality of finished；Anode joint generally uses the life-span and exists
3
About Nian, this also makes production cost increase accordingly, and at anode carbon block end of lifetime, the thinnest anode anode scrap thickness, necessarily brings charcoal pole conduction inequality, and then cause electrolysis bath fluctuation of operating conditions, and power consumption increases.Want to improve the occupation mode of existing anode carbon block, realize the production of non-residual electrode, to reduce cost, it it is not only improvement anode carbon block, must be that whole system relevant for anode carbon block is improved, and if the transformation of existing aluminium cell groove to be stopped, fire resistant heat preserving structure in pot superstructure and bottom pot shell, anode stub, cathode carbon pieces etc. are scrapped completely, lose huge, and the expense that the structures such as bus above electrolysis bath, portal frame remanufacture is the highest.
Summary of the invention
It is an object of the invention to, it is provided that a kind of anode carbon block attachment structure and method.The present invention has anode carbon block simple in construction, easy to connect, it is achieved non-residual electrode produces, the features such as improvement cost is low.
Technical scheme: a kind of anode carbon block attachment structure, including carbon block body, carbon block bodies top and bottom are respectively provided with fixing plush copper and the fixed groove that upper and lower anode carbon block is connected with anode carbon block.
Aforesaid anode carbon block attachment structure, is provided with through hole between described fixing plush copper and fixed groove.
Aforesaid anode carbon block attachment structure, described carbon block body is provided with more than one pair of fixing plush copper and fixed groove.
Aforesaid anode carbon block attachment structure, described fixing plush copper be cylinder, vertebral body or cross section be polygonal cylinder, the shape of fixed groove is corresponding with fixing plush copper.
The method of attachment that anode carbon block attachment structure uses, by the fixing plush copper and fixed groove being arranged on carbon block bodies top and bottom, new and old carbon block body is connected, and in the gap between fixing plush copper and fixed groove, new and old carbon block body is fixed together by filling sintering feed or pouring material.
Aforesaid anode carbon block method of attachment, puts into pouring material by the through hole between fixing plush copper and fixed groove.
Compared with prior art, the present invention is when changing anode carbon block, steel pawl is separated with old anode carbon block, new anode carbon block is placed on old anode carbon block, fixing plush copper is corresponding with fixed groove to be connected, and put into sintering feed between fixing plush copper and fixed groove, by the temperature of old anode carbon block, new and old anode carbon block sintering is connected.Or being provided with through hole between fixing plush copper and fixed groove, put into pouring material, poured by new and old anode carbon block and link together, pouring material also can first be coated on old anode carbon block, is placed on old anode carbon block by new anode carbon block immediately after.Now the old anode carbon block of lower section can carry out load-bearing by the auxiliary positioning groove connection one auxiliary hook of side.After new anode carbon block is changed, new anode carbon block is fixed and load-bearing still through the steel pawl at top, old anode carbon block is then linked together with new anode carbon block by fixing plush copper and fixed groove, due to the oldest anode carbon block scaling loss major part, and have major part to be immersed in the electrolyte of electrolysis bath, and electrolyte has buoyancy to anode carbon block, so attachment force needed for the oldest anode carbon block little, by the sintering between fixing plush copper and fixed groove or pour mode and old anode carbon block can be connected firmly.
The anode carbon block structure that before present invention applicant, a kind of pre-calcining electrolytic cell non-residual electrode of application produces, Application No.
