Abstract
An attachment is arranged on the lateral side of aluminum electrolytic bath. The utility model comprises a bath lateral side and coverplates around the upper bath. It is characterized in that a plurality of profiled plates are welded on a combining site of the bath lateral side and the coverplate; a triangle hole is embedded in the combining site. The profiled plate is an inequilateral quadrilateral shape. The welded seam of the bath lateral site is longer than that of the coverplate around the upper bath. The bottom edge of steel plate is not lower than the top edge of the cathode steel bar. The utility model, with good heat-sinking capability, is simple in structure, easy in construction. Moreover, it can prevent the creep deformation of bath, thus prolong electrolytic bath's life time.
Description
Technical field
The utility model belongs to the technical field of aluminum cell structure, is specifically related to a kind ofly alleviate and prevent the large-scale aluminum electrolytic cell pot shell and be subjected to thermal stresses and load-bearing and produce the new solution of distortion.
Background technology
The outer hull of aluminium cell is welded by steel plate, and housing is because of being subjected to built-in thermal stress and load-bearing meeting generation creep strain.Simultaneously, in the electrolysis production process, inside has a large amount of caloric requirements to distribute, to keep the rational thermal equilibrium of electrolytic process and groove thorax inwall ionogen forms complete crust.Therefore in fact the electrolyzer pot shell promptly plays the effect that keeps the slot liner shape; Play the effect of heat radiation again.At present, two functions of this of pot shell are separated, and keeping the slot liner shape is to be finished at the U one type bassinet stand of pot shell outside by hoop; The sidepiece heat radiation then is to finish by sidepiece outer natural ventilation or forced convection mode.Recently the someone has proposed some radiator element of welding on the pot shell outer wall, but can only being implemented in sidepiece, this method increases the part area of dissipation, but since the steel plate that welded be positioned at pot shell top, all side coamings below, heat still is difficult for shedding with air flowing, also underuse the heat radiation potentiality of top periphery coaming plate, its effect is extremely limited.
The utility model content
The utility model proposes a kind of additional unit of sidepiece reinforcing structure of large-scale aluminum electrolytic cell, it promptly can play the effect that increases cell sidewall intensity; Can make full use of the area of pot shell top periphery coaming plate and the area that this device itself is increased again, increase radiating effect.
The sidepiece additional unit of large-scale aluminum electrolytic cell of the present utility model, comprise pot shell sidewall and pot shell top periphery coaming plate, it is characterized in that some deformed steel flats of welding between pot shell sidewall and pot shell top periphery coaming plate, deformed steel flats leaves a leg-of-mutton hole near pot shell sidewall and pot shell top periphery coaming plate combining site place.
Deformed steel flats of the present utility model can be a unequal-sided tetragon, and the length of weld seam is greater than the length with weld seam between the pot shell top periphery coaming plate between itself and the pot shell sidewall.The steel plate bottom is as the criterion to be not less than the cathode steel bar upper edge.
Deformed steel flats of the present utility model, between per two groups of bassinet stands of cell sidewall, weld 2～3, its thickness is 5～20mm, be 300～600mm with the length that the pot shell sidewall welds mutually, and the length of welding portion is 50～120mm between the pot shell top periphery coaming plate.
The sidepiece additional unit of large-scale aluminum electrolytic cell of the present utility model, get final product the intensity of strengthening groove shell side wall and pot shell top periphery coaming plate, can utilize the area strengthening groove shell side wall heat radiation of all side coamings of pot shell and deformed steel flats again, and leave hole in bight, three intersection, be convenient to the transverse flow of air, its radiating effect is remarkable especially.
When design of the present utility model was tried out in large-scale aluminium manufacturer of certain cooperation unit inside, because simple in structure, easy construction, its effect was fairly obvious again, gets a good review.Confirmed as not only by manufacturer that radiating effect obviously improves, also can prevent the pot shell gross distortion, reduce inner lining damage, thereby promptly prolong life-span of electrolyzer the working life that can help improving large-scale aluminum electrolytic cell.Be expected to obtain tangible economic benefit after applying.
Description of drawings
Fig. 1 is that master of the present utility model looks synoptic diagram;
Fig. 2 is the utility model schematic side view;
Fig. 1,1 pot shell top periphery coaming plate; 2 pot shell sidewalls; 3 deformed steel flats; 4 pot shell bassinet stands.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described and replenishes.As shown in drawings, between aluminum cell casing top periphery coaming plate 1 and pot shell sidewall 2, add weldering deformed steel flats 3.Pot shell top periphery coaming plate is the angle that is close to 90 ° of angles usually with the pot shell sidewall, and deformed steel flats leaves a leg-of-mutton hole combining the position near pot shell top periphery coaming plate with the pot shell sidewall, and this helps the horizontal circulation of air.
The deformed steel flats plane is irregular tetragon.Because it is welded as a whole with pot shell top periphery coaming plate, pot shell sidewall, has not only reinforced the electrolytic bath shell structure, and has increased the area of dissipation of electrolytic bath shell side wall greatly.Deformed steel flats is with the length of weld seam between the pot shell sidewall length greater than weld seam between it and the pot shell top periphery coaming plate.
In implementation process, deformed steel flats thickness in the sidepiece additional unit of aluminium cell of the present utility model is 5～20 millimeters, it with the pot shell sidewall between mutually the length of welding portion (a) be 300～600 millimeters, its underpart is a standard to be not less than the cathode steel bar upper edge; And it is 50～120 millimeters with the length (b) of the welding portion between the pot shell top periphery coaming plate, and can suitably extend to side under the turbogrid plates adjacent with coaming plate.Deformed steel flats welds 2～3 between per two groups of bassinet stands in the utility model between the bassinet stand on the pot shell of electrolyzer side, like this at large-scale or super-huge aluminium cell, and about altogether about 50～170 of the deformed steel flats both sides of this device.
Be the concrete technical parameter that sidepiece additional unit of the present utility model is installed on the large-scale and super-huge aluminium cell of 300KA below:
| Specification | a(mm) | b(mm) | Thickness | The sheet number |
| 300KA | 300-600 | 50-120 | 5-20 | 50-120 |
| 360KA | 300-600 | 50-120 | 5-20 | 90-150 |
| 500KA | 300-600 | 50-120 | 5-20 | 100-170 |
