Description
Technical field
This utility model is related to a kind of anode carbon block in Aluminum Electrolysis Production field, particularly a kind of continuous prebake anode
Carbon block.
Background technology
Modern Aluminium Industry, generally produces electrolytic aluminium using prebaked anode.2～4 are provided with anode carbon block upper surface
A diameter of 160～180mm, the deep circular groove for 80～110mm, is commonly called as charcoal bowl, and in anode assembling, charcoal bowl is used for installing anode claw
Head, and anode joint is cast in charcoal bowl with the phosphorus pig iron, anode joint and aluminum conducting rod are connected by aluminum steel blast weldering, then
Aluminum conducting rod is closely connected with anode carbon block, constitute anode carbon block group.During Aluminum Electrolysis Production, anode carbon block can be because of which
Constantly reaction discharges carbon dioxide and constantly consumes the oxygen for decomposing out with alumina eltrolysis at high temperature, therefore anode carbon block
Periodic replacement is needed, remaining carbon block is commonly called as anode anode scrap after replacing.At present the production technology is primarily present following shortcoming, and 1）Change
New anode carbon block is in normal-temperature, could be conductive Jing after preheating in about 24 hours in electrolysis bath to be put into, therefore changes anode carbon
Block increases can heat loss, and very big to the stable working impact of electrolysis bath during change poles；2）The replacing of anode can be given birth to aluminium electroloysis
Producing to be formed periodically affects, and destroys the energy and material balance of electrolysis bath, affects current efficiency, increases power consumption rate；3）In order to
Anode joint is separated with anode anode scrap, needs to break the charcoal bowl at phosphorus pig iron casting into pieces, make anode anode scrap de- from anode joint
Fall to realize separating, the process not only takes, and labor strength is big, efficiency is low；4）Anode anode scrap under changing is produced
Amount is generally the 10%～15% of aluminium ingot yield, calculates for 26,000,000～27,000,000 tons/year by China's aluminium ingot yield, annual generation
Anode anode scrap is 2,600,000～3,900,000 tons/year, and according to 2700 yuan/ton of calculating of anode carbon block, annual China can waste value up to hundred
Hundred million yuan of anode carbon block；4）Because anode carbon block has 25%～27% porosity in itself, therefore anode anode scrap internal adsorption is substantial amounts of
Electrolyte, the main component of electrolyte is fluoride salt, and the anode anode scrap environmental pollution containing a large amount of fluoride salts is extremely serious；5）
When just anode joint is cast in charcoal bowl, in order to reduce the waste of anode anode scrap, it is necessary to anode anode scrap is burnt thin, in sun as far as possible
Pole carbon block end of lifetime, the top surface of anode carbon block are sufficiently close to electrolyte level face, by magnetic field and airflow influence, bath surface
Constantly there is strong wave to produce, in actual production process, anode joint is often corroded by electrolyte, the ferrum element of anode joint
Dissolve in electrolyte, immediately into aluminium ingot, affect quality of finished；Anode joint generally uses the life-span at 3 years or so, and this also makes life
Producing cost accordingly increases, and in anode carbon block end of lifetime, excessively thin anode anode scrap thickness, necessarily brings charcoal extremely conductive uneven,
And then cause electrolysis bath fluctuation of operating conditions, power consumption to increase.Want to improve the occupation mode of existing anode carbon block, realize the life of non-residual electrode
Produce, with reduces cost, not exclusively improve anode carbon block, it is necessary to be that the related whole system of anode carbon block is improved, and
If existing aluminium cell will stop groove transformation, fire resistant heat preserving structure, anode stub in pot superstructure and bottom pot shell,
Cathode carbon pieces etc. are scrapped completely, lose huge, and the expense also ten that the structure such as bus, portal frame above electrolysis bath is remanufactured
Divide high.
The content of the invention
The purpose of this utility model is, there is provided a kind of continuous prebake anode carbon block.This utility model has realizes nothing
Anode scrap is produced, the low feature of improvement cost.
The technical solution of the utility model：A kind of continuous prebake anode carbon block, including carbon block body, above carbon block body
Link slot is provided with, carbon block bodies top and bottom are respectively equipped with the fixed plush copper and fixed groove being correspondingly arranged.
In aforesaid continuous prebake anode carbon block, between the fixed plush copper and fixed groove, through hole is provided with.
In aforesaid continuous prebake anode carbon block, described this body side surface of carbon block is provided with auxiliary positioning groove.
In aforesaid continuous prebake anode carbon block, the connection slot cross-section is L-type.
Compared with prior art, this utility model is provided with link slot on the carbon block body of anode carbon block, during use, passes through
Steel pawl is connected with link slot, and anode carbon block is fixed.In jointed anode carbon block, steel pawl is separated with old anode carbon block, new
Anode carbon block be placed on old anode carbon block, fixed plush copper connection corresponding with fixed groove, and in fixation plush copper and anchor
Pouring material or sintering feed are put between groove, new and old anode carbon block is linked together.Now the old anode carbon block of lower section can pass through
The auxiliary positioning groove connection one of side aids in hook to carry out load-bearing, and the bottom that cross-arm is placed on anode carbon block may also be employed, and cross-arm is again
Directly fork holds carbon block to carbon block bottom for connection suspension rod or fork truck.After new anode carbon block connection is finished, new anode carbon block still leads to
The steel pawl for crossing top is fixed and load-bearing, and old anode carbon block is then connected to one with new anode carbon block by fixed plush copper and fixed groove
Rise, due to now old anode carbon block, scaling loss is most of, and has major part to be immersed in the electrolyte of electrolysis bath, and electrolyte is to sun
Pole carbon block has buoyancy, so now the attachment force needed for old anode carbon block is simultaneously little, by between fixed plush copper and fixed groove
Sintering or old anode carbon block is connected firmly by pouring mode.
This utility model can realize the continuous use of pre-baked anode carbon blocks non-residual electrode production, meanwhile, the knot of anode carbon block
Less, existing anode carbon block production system transformation is little for structure and existing anode carbon block structural difference.And sun of the present utility model
Pole carbon block when in use, transforms also little to existing electrolysis bath, and bus not to upper part of the electrolytic cell, portal frame etc. are transformed,
Only need to company of transformation steel receiving grab, and complete by increasing auxiliary hook, reduce the cost that existing electrolytic aluminium plant is transformed.This practicality is new
The anode carbon block structure that a kind of pre-calcining electrolytic cell non-residual electrode applied before type applicant is produced, Application No.
201610104972.4, using the exposed T-shaped connection plush copper of surrounding, by comparison, the application is connected the application using built-in L-type
Connect, residual carbon block highly ratio is lower with the carbon block of T-shaped connection, when L-type clamping screw bottom is less than electrolyte level line height, charcoal
Block can continue to protect L-type clamping screw not corroded by electrolyte；The upper surface of carbon block body is made to become a plane, can
Make old carbon block and the conducting surface of new carbon block connect more reliable, also allow for steel pawl and contact and cover entirely with carbon block surface in planar fashion
Lid, when removing steel pawl and connecing pole, carbon block upper surface there is no other impurity, and need not clear up carbon block upper surface, make to connect pole work
It is succinct smooth.
