Abstract
The utility model discloses an aluminum electrobath anode carbon block with exhaust holes. A plurality of up-down through-holes are arranged in the anode carbon block; the exhaust holes facilitate overflow exhaust during peat calcining process, as a result, the exhaust passage is shortened, the porosity is lowered, even calcining is achieved inside the peak, the stressing is even, cracking is not easy to occur, the homogeneity is sound and the intensity is strong. Therefore, the quality of anode carbon block is improved, and the anode carbon block can be heated rapidly during using the aluminum electrobath; the heat conducting and radiating performance of the carbon block is improved; the exhaust and the precipitation of the gases such as CO<2>/CO during aluminum electrolysis are facilitated; and as a result, the power consumption of aluminum electrolysis is reduced.
Description
Technical field: the utility model is a kind of novel aluminum electrolyzing cell used prebaked anode carbon block structure and preparation method.
Background technology: existing general aluminum electrolyzing cell used prebaked anode carbon piece is to be aggregate with after-smithing petroleum coke, pitch coke, coal-tar pitch is a cakingagent, through broken, screening, batching, mix and pinch, the mechanical shock moulding, make the rectangular shape of unitary solid, form through technology manufacturings such as roastings again.
Existing general anode block is in the sinter process process, the inner flue gas volatile matter that produces of carbon piece is discharged from inside to outside, because the carbon block is long-pending more too, deflated passage (microscopic void) is long more, easily causes the porosity of finished product carbon piece higher, and in the intensification temperature-fall period, carbon piece inside and outside is heated to non-uniform temperature, the diffusion of thermal stresses and contraction are also inconsistent, and it is even also easily to produce carbon piece density unevenness, defectives such as crackle is more, easy fracture.
Its final product is after being applied to aluminium cell production, because carbon piece bottom surface area is bigger, promptly is unfavorable for the rapid heating of carbon piece, produces the heat conduction non-uniform phenomenon, exists again to be unfavorable for the CO that aluminium electrolysis process is separated out
2Defectives such as gas purging such as/CO.
The defective that above-mentioned existing general heavy anode carbon piece produces in the manufacturing and electrolysis application, along with the development of aluminium cell maximization and the increasing of anode block external form volume, then show especially more, the existence of these defectives has not only reduced the quality and the yield rate of anode block, but also has increased the power consumption cost of electrolysis of aluminum accordingly.
Content of the present invention: the purpose of this utility model is defective and the deficiency that produces in the application of above-mentioned production sinter process of now general heavy anode carbon piece and Aluminium Electrolysis in order to overcome.A kind of new anode carbon block for aluminium electrolysis tank structural texture is provided, and the manufacture method that realizes this structure.
The utility model is a kind of novel aluminum electrolyzing cell used prebaked anode carbon piece, and its technical scheme is: making several venting holes that connect mutually up and down on the anode block inside between end face and the bottom surface.Its venting hole along continuous straight runs cross section can be designed to circle, also can be designed to ellipse, or both sides are to be square rectangle in the middle of the circular arc;
Venting hole in the anode block can once be made in shaping carbon block technology by the drilling tringle that is installed on the carbon piece vibrating forming machine, also can hole on roasting anode block in previous existence after the moulding and produce acquisition.For venting hole in the making processes and drilling tringle are easy to the demoulding, the drilling tringle can have certain taper slightly.
In anode block production and aluminium cell production, adopt design advantage of the present invention to be: the exhaust hole of several up/down perforations in the anode block indoor design, in producing sinter process, the carbon piece is easy to the discharging of overflowing of volatile matters such as flue gas that tar produces, can shorten the exhaust-duct, reduce porosity, make the inner roasting thermally equivalent of carbon piece, stress equilibrium, be difficult for cracking, uniformity is good, the intensity height has not only improved anode block and has produced the quality of product, and has been with the anode block of venting hole to be easy to rapid heating in the aluminium cell use, improve carbon piece heat conduction and heat radiation performance, be of value to CO in the electrolysis of aluminum
2Gas purgings such as/CO are separated out, thereby reach the purpose of joint medicine electrolysis of aluminum power consumption.

Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the semi-section side-view of Fig. 1
Wherein: (1) anode block, (2) ferrophosphorus ring carbon bowl, (3) venting hole
Embodiment: the utility model is a kind of anode block with venting hole, its manufacturing process is basic identical with the manufacturing process that shows general heavy anode carbon piece, its difference part is: in former real core anode block (1) inside, outside the ferrophosphorus ring carbon bowl (2), design and produce the venting hole (3) of several up/down perforations.
Venting hole (3) obtains, and can install several venting holes (3) moulding tringle on existing vibrating forming machine, once makes when vibrating forming carbon piece (1).
The transversal section of moulding tringle can be circular, also can be ellipse, can also be the rectangle of two ends band circular arc, thereby makes and the corresponding hole shape of tringle section that is shaped; The moulding tringle can have certain taper in two ends up and down slightly, fills the cleaning of coking material in the back demoulding and the roasting final vacuum hole so that carbon piece venting hole is shaped.
The anode block of the utility model band venting hole installation and using method on aluminium cell is identical with existing general anode block, in the anode block venting hole of up/down perforation in aluminium electrolysis process, the CO that can separate out generation
2Gases such as/CO discharge; And can be used as heat dissipation channel, logical the closing of exhaust hole can be by adding a cover the aluminum oxide charge level or adjusting with its method.
Drilling on used for aluminium electrolysis anode block system technology, using method and the application purpose and the honeycomb briquette of the utility model band venting hole, using method and the similar a bit part of application purpose.
