Abstract
The utility model discloses a feeding port structure of a refined aluminum tank. A feeding port (5) is arranged on the upper portion of the refined aluminum tank, a graphite layer (8) is arranged on the lower portion of a vertical section of the feeding port (5), the upper end of the vertical section of the feeding port (5) is made by laying a magnesite brick layer (9), and a liner (7) is adjacent to the graphite layer (8) and the magnesite brick layer (9). The number of the feeding port (5) is 1. The feeding port structure of the refined aluminum tank is improved, oxidation resistance of the feeding port is improved, the using time of the feeding port can be prolonged, and accordingly the service life of the refined aluminum tank is prolonged.
Description
Technical field
The utility model relates to a kind of refined aluminum groove charging opening structure.
Background technology
The refined aluminium electrolyzer is the main equipment that refined aluminium is produced, and in refined aluminium is produced, generally adopts three layers of liquid electrolytic process, and raw material is the primary aluminum of big electrolysis production, and product is the high purity refined aluminium.As shown in Figure 1; Refined aluminum groove is made up of the charging opening of limit portion and the tank room at middle part, and the bottom of charging opening and tank room is a UNICOM, and raw material adds from charging opening; After stirring, overflow to tank room from the bottom; Tank room has three layers of liquid: orlop is the anode copper alloy, by treating that purified primary aluminum and weighting agent copper forms, links to each other with the bottom land carbon anode; Middle one deck is an ionogen; Topmost be to join the raffinal of refining gained with the aluminium negative electrode.3.0,2.7,2.3g/cm under 720 ~ 760 ℃ service temperature, (proportion of three kinds of melts is respectively: to utilize density difference between anode copper alloy melt, ionogen and negative electrode refined aluminium melt
3), make the state that is remaining three layers of liquid in the electrolyzer, thereby raw material and finished product are separated.
The ultimate principle of three layers of liquid electrolytic refining process is: utilize the density difference of refined aluminium, ionogen and anode copper alloy to form the liquid layering, under galvanic effect, the aluminium that electrochemical reaction takes place in the melt is in the anode alloy carries out electrochemical dissolution, generates Al
3+Ion: Al-3e=Al
3+
Al
3+Ion gets into after the electrolytic solution, on negative electrode, discharges, and generates metallic aluminium: Al
3++ 3e=Al
And elements such as Cu, Si, Fe do not dissolve in the alloy, in the finite concentration scope, only accumulate in the anode alloy, and this is because its current potential all just in aluminium, and also has the cause of q.s aluminium in alloy.And the element that several kinds of current potentials such as the Na that is mingled with in the alloy, Ca, Mg are defeated by aluminium dissolves with aluminium together, generates Na
+, Ca
2+, Mg
2+Entering electrolytic solution also gathers, and under finite concentration, temperature and current density, these impurity can not discharge on negative electrode.Therefore on negative electrode, obtain the higher refined aluminium of purity.
Refined aluminium charging of the cell mouth is positioned at groove thorax sidepiece, is the admission passage of raw material, and raw material flows into tank room from riser, shown in accompanying drawing 1 after the charging opening fusing and stirring.In the prior art; Charging opening is built by laying bricks or stones by 4 graphite blocks and is formed, and reaches the top from the bottom always, because in refined aluminium is produced; Feed molar ratio is more frequent; Oxidation was more serious when the common graphite charging opening at high temperature contacted with air, can shorten the duration of service of charging opening so greatly, also just shortened the cell life of refined aluminum groove.
Summary of the invention
The purpose of the utility model is: a kind of novel refined aluminum groove charging opening structure is provided; Warm air directly contacts with the graphite charging opening at top when overcoming reinforced that prior art exists; Thereby the generation severe oxidation shortens duration of service of charging opening greatly, shortens the deficiency in refined aluminum groove life-span.
The structure of the utility model is such: on refined aluminum groove top charging opening is set, at the vertical pars infrasegmentalis of charging opening graphite linings is set, be built into the magnesia brick layer in vertical section upper end of charging opening, what face mutually with graphite linings and magnesia brick layer is liner.
The quantity of charging opening is 1.
When reinforced, warm air at first contacts with magnesia brick, and the resistance of oxidation of magnesia brick is stronger, can effectively protect charging opening like this; And the graphite charging opening changes an all-in-one-piece charging opening into by 4 original assembly units, and the trust of monobloc(k)type charging opening and impact resistance all are better than the piecing assembly charging opening.
Owing to adopted technique scheme, improved refined aluminum groove charging opening structure, improved the oxidation resistent susceptibility of charging opening, can prolong the duration of service of charging opening, thereby the cell life of refined aluminum groove is provided.

Embodiment
The embodiment of the utility model: on refined aluminum groove top charging opening 5 is set, the quantity of charging opening 5 is 1, can practice thrift cost like this; Vertical pars infrasegmentalis at charging opening 5 is provided with graphite linings 8, is built into magnesia brick layer 9 in vertical section upper end of charging opening 5, and what face mutually with graphite linings 8 and magnesia brick layer 9 is liner 7.
Magnesia brick layer 9 is built 2 ~ 3 layers by laying bricks or stones.Magnesia brick is more high temperature resistant than graphite material, antioxidant.
