The structure for preventing distortion of large-scale electrolysing cell shell is as follows: a shroud ring (3) is connected with a crade frame (2) in the aluminium electrolysing cell shell (1). The structure provided by the utility model can solve upper arching problem of the electrolysing cell bottom in the aluminium electrolysing cell baking start process, at the same time reduce distortion of large and small surfaces, the structure prevents cathode disrepair, and is convenient for producing operation, prolongs service life of the electrolysing cell; the structure has simple structure, is convenient for operation, and is easy to realize, has obvious effect and wide market prospect.
Description
Technical field
The utility model relates to a kind of large-scale aluminum electrolytic cell pot shell deformed configurations that prevents, belongs to the aluminum cell structure technical field.
Background technology
The large vol aluminium cell phenomenon of bakie often occurs at the roasting and starting initial stage, and this mainly is to be occurred damagedly by negative electrode, and ionogen and aluminium liquid seepage cause.In the roasting and starting process, the temperature of electrolyzer rises to production temperature (950～960 ℃) by room temperature, because pot shell self exists thermograde and inner lining material expanded by heating, very easily causes the bottom land arch.The bottom land arch makes negative electrode early damage occur on the one hand easily, causes bakie in the roasting and starting process; On the other hand, easily cause the difficulty of production operation.It mainly shows as the pole span disunity, distribution of current inequality, electrolyzer production instability etc.Therefore, the bottom land arch is very harmful to electrolyzer, not only reduces cell life, and influences the production operation of electrolyzer greatly, this phenomenon ubiquity on large-scale aluminum electrolytic cell.
The utility model content
Technical problem to be solved in the utility model is: a kind of large-scale aluminum electrolytic cell pot shell deformed configurations that prevents is provided, and the arch that it has solved cell bottom influences the problem of the production operation of electrolyzer, can prolong the life-span of electrolyzer.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of large-scale aluminum electrolytic cell pot shell deformed configurations that prevents, connects shroud 3 between the bassinet stand 2 around the aluminum cell casing 1.
Described bassinet stand 2 is closed with the integral body that shroud 3 constitutes.
Described bassinet stand 2 opens wide with the integral body that shroud 3 constitutes.
Described shroud 3 is connected between two adjacent bassinet stands 2.
Described shroud 3 connects a plurality of bassinet stands 2 simultaneously.
Between described shroud 3 and the bassinet stand 2 for being welded to connect.
Described shroud 3 connects by the bolt handle with bassinet stand 2.
The two ends of described shroud 3 are connected on the bassinet stand wing plate 4.
The two ends of described shroud 3 are connected on the bassinet stand riser 5.
Described shroud 3 is arranged on the position near pot shell upper edge hole 6.
Advantage of the present utility model and effect are: it has solved the arch problem of bottom land in the roasting and starting aluminum electrolytic cell process effectively, reduces large and small distortion simultaneously.This method had both prevented the appearance of negative electrode disrepair phenomenon, had made things convenient for production operation again, had prolonged the work-ing life of electrolyzer.The utility model is simple in structure, and operating aspect is easy to realize that effect is obvious, has market outlook.
