Abstract
The present invention relates to an electrolytic aluminium production process by a prebaked anode adhesive method, which is a new process used for an anode in electrolytic aluminium production. The structure of a prebaked anode carbon block is changed slightly; the upper edges of both sides of the carbon block are provided with clamping grooves; a steel clamping tool is used for clamping the clamping grooves; the upper surface of the steel clamping tool is connected with an aluminium guide rod; when an old carbon block is consumed to a certain degree, the steel clamping tool is removed for clamping a new carbon block for standby; after the surface of the old carbon block is cleaned, a layer of coal pitch and anode paste is coated; the new carbon block is placed on the surface; after the surface, the coal pitch and the anode paste are sintered into a whole, production can be carried out. The present invention has the advantages of simple process, convenient operation, environmental protection and sanitation, saves 25% to 30% of anode carbon blocks than an original prebaked anode production process, and reduces the production cost of electrolytic aluminium by 300 yuan/ton. The present invention is suitable for all electrolytic aluminium manufacturers by the prebaked anode method to use.
Description
One, technical field
The present invention relates to a kind of novel process that anode uses in the Aluminum Electrolysis Production.
Two, background technology
At present, Aluminum Electrolysis Production mainly adopts soberberg anode and two kinds of production technique of prebaked anode.Soberberg anode is to utilize anode mix electrolytic anode of forming of roasting voluntarily in the Aluminum Electrolysis Production process, and this technology is owing to seriously pollutedly be eliminated gradually.Prebaked anode is with anode block roasting moulding in advance, and then is installed to electrolytic aluminium anode and puts into production.Prebaked anode is just generally adopted with its oligosaprobic advantage.But prebaked anode also has its outstanding shortcoming, and that is exactly that it can not all be utilized in process of production, and the anode scrap that produce 25-30% can not be utilized, and causes very big waste, has had a strong impact on the Aluminum Electrolysis Production cost.
Three, summary of the invention
The root problem that the present invention will solve is: design a kind of novel process of utilizing the prebaked anode bonding method to produce electrolytic aluminum, this technology can not have the anode anode scrap in the Aluminum Electrolysis Production process, prebaked anode is all utilized, thereby reduces the Aluminum Electrolysis Production cost, reduces the pollution of anode scrap to environment.
It is to reserve steel pawl tapping hole on the prebaked anode carbon piece that present anode uses, and the steel pawl with the aluminium guide bar bottom is cast on the carbon piece tapping hole again.
Technology of the present invention is such: upper limb is provided with support slot in prebaked anode carbon piece symmetry two sides, do not re-use the steel pawl, there is a steel jig can snap in symmetric two support slots, on the steel jig, be provided with thru-bolt, can symmetric two steel jigs are fastening, in case the landing of carbon piece is connecting aluminium guide bar above the steel jig, the soft end of being with of conductive aluminum connects aluminium guide bar one end connection steel jig.When anode block is depleted to a certain degree, the steel jig comes loose, remove aluminium guide bar, stand-by with new carbon piece of steel jig card, needn't open the shell face again, only need old carbon piece upper surface is cleaned out, on the carbon piece, be coated with one deck pitch and anode mix then, treat after anode mix is softened new carbon piece to be put, chucking steel jig and aluminium guide bar, bonding anode working finishes.After treating the anode mix sclerosis, two are sintered to one up and down, and production can continue.
Positively effect of the present invention is: technology is simple, and is easy to operate, can reach the same environmental requirement of former prebaked anode production technique fully; Anode block than existing prebaked anode production technique saving 25-30% greatly reduces the Aluminum Electrolysis Production cost; Need open the electrolytic bath shell face during prior art production technique change poles, this technology does not need, the time and labour saving.
Four, description of drawings
Fig. 1 is the application synoptic diagram of technology of the present invention; Fig. 2 is the vertical view of Fig. 1.
Five, embodiment
As shown in drawings, reserve two symmetric support slots 7 at prebaked anode carbon piece 4 two sides upper limbs, have a steel jig 3 can block support slot 7, steel jig 3 is connected with top aluminium guide bar 1 via a bolt, and conductive aluminum is soft is with 2 to be connected between aluminium guide bar 1 and the steel jig 3; Steel jig 3 both sides can be fastening by a thru-bolt; When prebaked anode is an old carbon piece 6 when being depleted to a certain degree, the thru-bolt on the steel jig 3 that comes loose removes aluminium guide bar 1, stand-by with new carbon piece of steel jig 3 cards, needn't open the electrolytic bath shell face, only need old carbon piece 6 surface-conditionings are clean, be coated with one deck coal-tar pitch and anode mix thereon, treat after anode mix is softened new carbon piece to be put, chucking steel jig 3 and aluminium guide bar 1, bonding anode working finishes, treat the anode mix sclerosis after, the bonding surface 5 of two carbon pieces is sintered to one up and down, and production can continue.
