Support structure of aluminum electrolytic cell
Technical field
The utility model relates to a kind of aluminium cell, particularly a kind of installation supporting structure of large-scale aluminum electrolytic cell.
Background technology
At present, existing support structure of aluminum electrolytic cell mode adopts more is placed bench insulator (plate) on foundation of civil work, place crossbeam on bench insulator, will be positioned on the crossbeam with the electrolyzer of bassinet stand at last.Along with the increasing gradually of electrolyzer capacity, it is big that the weight of electrolyzer production and the displacement of thermal expansion also begin to become now.Therefore, because the caused frictional force that expands also becomes greatly, associated components and foundation of civil work are carrying bigger frictional force, and be big to the horizontal thrust on concrete basis, and the stability on this basis is had a negative impact.
Summary of the invention
The purpose of this utility model provides a kind of electrolyzer supporting structure, the horizontal thrust that this supporting structure makes aluminium cell thermal strain displacement in process of production produce acts on the concrete basis by the rolling resistance mode, to reduce horizontal thrust, overcome the deficiencies in the prior art to the concrete basis.
In order to solve the problems of the technologies described above, the utility model is taked following basic technical scheme: place rolling insulated leg 3 on concrete basis 4, directly place the aluminium cell 1 of band bassinet stand on rolling insulated leg 3.
The utility model also can be taked following technical scheme (being alternative plan): place rolling insulated leg 3 on concrete basis 4, crossbeam 2 is set on rolling insulated leg 3, the aluminium cell 1 of band bassinet stand is placed on the crossbeam 2.
Rolling insulated leg 3 in the above technical scheme is core integral parts, it is made up of upper member plate 5, lower member plate 10, upper insulation plate 6, lower insulation plate 9, rolling member 7, rolling web member 8, upper insulation plate 6, lower insulation plate 9 are connected with upper member plate 5, lower member plate 10 respectively, and rolling member 7 is placed between upper insulation plate 6, the lower insulation plate 9 after connecting by rolling web member 8.It is the effect of rolling resistance that the rolling insulated leg has played the change sliding friction, has also played the effect of traditional cell insulation pad simultaneously.
The utility model has the advantages that:
The utility model has adopted the rolling insulated leg, makes electrolyzer support contact surface and changes rolling resistance into by sliding friction, thereby reduced the horizontal thrust between bracing member, has increased basic stability;
Basic technical scheme of the present utility model has been simplified traditional supporting way, thereby saves construction investment.

Embodiment
Embodiment of the present utility model:
Embodiment one, is basic technical scheme of the present utility model, and its structure is seen Fig. 1, places rolling insulated leg 3 on concrete basis 4, places the aluminium cell 1 of band bassinet stand on rolling insulated leg 3.
Embodiment two, are second technical scheme of the present utility model, and its structure is seen Fig. 2, place rolling insulated leg 3 on concrete basis 4, and crossbeam 2 is set on rolling insulated leg 3, and the aluminium cell 1 of band bassinet stand is placed on the crossbeam 2.
In above two embodiment, the structure of rolling insulated leg 3 is seen Fig. 4, it is made up of upper member plate 5, lower member plate 10, upper insulation plate 6, lower insulation plate 9, rolling member 7, rolling web member 8, upper insulation plate 6, lower insulation plate 9 are connected with upper member plate 5, lower member plate 10 respectively, and rolling member 7 is placed between upper insulation plate 6, the lower insulation plate 9 after connecting by rolling web member 8.Wherein rolling member 7 is made of solid or hollow roller, and each rolling insulated leg 3 contains two or more rolling members 7.
Rolling insulated leg 3 should not have bite flexibly, and its surface and the susceptor surface that is in contact with it are all answered bright and clean no overlap and burr.
To the support of whole aluminium cell, the utility model is to implement like this, in the aluminium cell end support combinations 11 is set; On the aluminium cell length direction, between the Support Position, both ends support combinations 12 can be set, one or more support combinations 12 also can be set as required.Support combinations 11 and support combinations 12 are meant and comprise more than one and one by rolling insulated leg 3 point of suppon that concrete basis 4 constitutes.
