Abstract
The utility model relates to a pre-baked anode for aluminium electrolysis. A gas diversion groove is formed at the bottom of an anode basal body of the anode, longitudinal holes are formed on the anode basal body and penetrate through the anode basal body, and transverse holes are formed on the side edges of the anode basal body and communicated with the longitudinal holes. In the structure, the gas diversion groove is formed at the bottom of the anode, and the longitudinal holes and the transverse holes which are communicated with each other are formed, which has obvious promoter action to aluminium electrolysis. On one hand, the residence time of bubbles at the bottom of the anode and the coverage rate of the bubbles at the bottom of the anode can be reduced, the noise voltage brought forth by the bubbles at the bottom of the anode can be reduced, the gas film electric resistance at the bottom of the anode can be lowered and the contact area between the anode and electrolyte solution can be enlarged; on the other hand, as the contact area between the grooved anode and the electrolyte solution is large, the heat conduction can be accelerated, and accordingly, a newly-replaced anode body can be heated up quickly, thereby achieving the purposes of lowering the consumption of electrical energy and carbon blocks.
Description
Technical field
The utility model relates to a kind of used for aluminium electrolysis prebaked anode.
Background technology
Aluminium production technology level improve constantly with development in, the scale of Aluminum Electrolysis Production constantly enlarges, this specification and structural requirement to aluminium electrolysis prebaked anode is more strict.Therefore, adopt aluminium electrolysis prebaked anode rational in infrastructure, excellent performance, both can utilize raw material rationally and effectively, again can save energy and reduce the action cost, directly improve the economic benefit of Aluminium Electrolysis.
A corner crack difficult problem often appears in flat anode commonly used in the present aluminium industrial production technology, and flat anode ubiquity noise voltage height, anode bottom air film resistance height, problem that efficient is lower.For the monolithic anode on the electrolyzer, the anodic noise is directly reflected into the current density size of himself passing through, and its change frequency or cycle are the frequency or the cycle of bubble pressure drop, and the amplitude of variation is the amplitude of noise voltage.Anodic gas is the process that bubble is progressively grown up Zi producing the back to the process of discharging, because anodic gas is non-conductive, bubble is in the rising that will cause bath voltage of gathering of anode bottom.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of electrolytic efficiency height, noise voltage is low, anode bottom air film resistance is low used for aluminium electrolysis prebaked anode are provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of used for aluminium electrolysis prebaked anode comprises anode substrate, it is characterized in that: the anode substrate bottom has the gas flow guiding groove, has vertical hole on the anode substrate, and vertically the hole penetrates anode substrate, and the anode substrate side has transverse holes and is connected with vertical hole.
Described gas flow guiding groove is semi-enclosed structure, and it is open that the one end seals an end.
The beneficial effect that the utility model had is: this anode bottom has the air-flow guide path, and is furnished with the vertical hole and the transverse holes of mutual perforation, and Aluminium Electrolysis has been produced obvious facilitation.On the one hand, can reduce the residence time and the anode bottom bubble fraction of coverage of bubble, play and reduce the anode bottom noise voltage that bubble produced, reduction anode bottom air film resistance, increase the effects such as contact area of anode and electrolytic solution in the anode bottom.On the other hand,, thermal conduction is accelerated, be impelled the new anode body of replacing to be rapidly heated, thereby reach the purpose that reduces the consumption of power consumption and charcoal piece because the contact area of fluting anode and electrolytic solution is big.
Description of drawings
Fig. 1 is a prebaked anode structural representation in the utility model;
Among the figure: 1, anode substrate; 2, vertical hole; 3, transverse holes; 4, gas flow guiding groove.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, a kind of used for aluminium electrolysis prebaked anode comprises anode substrate 1, and anode substrate 1 bottom has gas flow guiding groove 4, has vertical hole 2 on the anode substrate 1, and vertically hole 2 penetrates anode substrate 1, and anode 1 matrix side has transverse holes 3 and is connected with vertical hole 2.It is open that gas flow guiding groove 4 preferred semi-enclosed structures, one end are sealed an end.Wherein vertically the aperture of hole 2 and transverse holes 3 is 20mm～50mm.
The used for aluminium electrolysis prebaked anode of this structure can increase exhaust and overflow aftereffect when not influencing electric current " surface action ", quicken the discharge to bottom surface aggregation bubble, thereby effectively reduce bath voltage, realizes reducing power consumption.Produce 1 ton of aluminium ingot, can reduce about 40～50 degree of power consumption; The prebaked anode of Thoughs consumes only and reduces more than 30～40kg/t-Al; Same anode weight is gone under the groove condition, can prolong about 0.5～1 day of work-ing life of anode.Open pod and be with communicating aperture can make the about 10kg of monolithic weight saving, ton aluminium carbon consumption can reduce 5.5kg.
