Abstract
The utility model discloses a hermetical tank hood of an insulating electrolytic bath. The hermetical tank hood comprises a positive hood and a negative hood, wherein the positive hood comprises a square pipe I, a big-face aluminum plate I, fiber paper I, an inner aluminum plate I and an inner steel plate I which are fixedly connected together; the negative hood comprises a square pipe II, a big-face aluminum plate II, fiber paper II, an inner aluminum plate II and an inner steel plate II which are fixedly connected together. The hermetical tank hood disclosed by the utility model can be used for solving the problem that the leakproofness of the tank hood of the electrolytic bath in the aluminum smelting industry is relatively poor, so that external air has difficulty in entering into the electrolytic bath and smoke in the bath is hard to overflow, and the ventilating power of a smoke exhaust fan of a smoke purifying system and the energy consumption of the electrolytic bath are greatly reduced, thereby reducing the loss of heat of the electrolytic bath and reducing the environmental pollution caused by smoke.
Description
Technical field
The utility model relates to a kind of groove cover, relates in particular to a kind of groove cover that is exclusively used in aluminum smelting technology industry electrolyzer.
Background technology
Traditional aluminum smelting technology industry cell construction is that plate frame and Special-shaped Plates overlap two classes, and plate frame structure intensity is better, but stopping property is poor and be not incubated, and not only undercapacity of Special-shaped Plates bridging arrangement is not also incubated.At present, the groove cover ubiquity stopping property that aluminum smelting technology industry electrolyzer uses is relatively poor, extraneous air easily enters flue gas in electrolyzer and in groove and overflows, cause the exhausting power of flue gas purification system smoke exhaust fan and the power consumption of electrolyzer higher, the smoke pollution environment overflowing, poor with time slot cover heat insulating ability, cause electrolyzer calorific loss.Along with the high speed development of aluminium electrolytic industry, improving electrolysis of aluminum utilization rate of electrical has become a core index of aluminium industry.And existing electrolytic bath cover can't solve sealing problem, environment has been caused to pollution, do not reduce the power consumption of electrolyzer yet.
Utility model content
For the problem of above appearance, the utility model aims to provide a kind of sealed thermal insulating electrolytic bath cover, by structural improvement, in aluminum smelting technology industry, use this electrolytic bath cover, effectively stop extraneous air and entered overflowing of flue gas in electrolyzer and in groove, greatly reduce the pollution to environment, meanwhile, this groove cover heat insulating ability is good, has also reduced the calorific loss of electrolyzer.
The utility model is achieved by the following technical programs:
A kind of hermetic type thermal insulation electrolytic tank groove cover, comprise sun cover, shadow mask, described sun cover comprises square tube I, large face aluminium sheet I, fibrous paper I, internal layer aluminium sheet I and inner layer steel plate I, and is fixed together between square tube I, large face aluminium sheet I, internal layer aluminium sheet I and inner layer steel plate I; Described shadow mask comprises square tube II, large face aluminium sheet II, fibrous paper II, internal layer aluminium sheet II and inner layer steel plate II, and is fixed together between square tube II, large face aluminium sheet II, internal layer aluminium sheet II and inner layer steel plate II.
Further, in order to strengthen the firm of electrolyzer Cao cover, the mode of connection between the square tube I of sun cover, large face aluminium sheet I, internal layer aluminium sheet I and inner layer steel plate I is welding; Mode of connection between the square tube II of shadow mask, large face aluminium sheet II, internal layer aluminium sheet II and inner layer steel plate II is welding, make Cao cover can be firm cover on electrolyzer.
Further, in order to strengthen the intensity of electrolytic bath cover structure, square tube I and square tube II adopt special-shaped square tube, have greatly increased the work-ing life of groove cover.Special-shaped square tube is made up to heterotypic material of each, and under identical external condition, (as temperature, pressure, field etc.), respectively there are differences along different directions to some performance of heterotypic material.By each special-shaped square tube of making to heterotypic material, it is more much better than than general steel pipe that it bears dynamics, makes the electrolytic bath cover made of steel tubes also more durable, extended work-ing life of groove cover.
Further, for hermetic type and the heat retaining property of strengthening groove cover, fibrous paper I and fibrous paper II adopt ceramic fiber paper, make, in the time using electrolyzer, to have greatly reduced the loss of electrolyzer heat, effectively improve the heat-insulating property of whole electrolyzer.
Further, for fear of the impact of the effect on fibrous paper, the material of inner layer steel plate I and inner layer steel plate II is stainless steel, the impact of not only having avoided steel plate to get rusty on airtight, the adiabatic effect of fibrous paper, also extend the work-ing life of groove cover, reduced production cost.
The beneficial effects of the utility model are: groove cover adopts the structure formation of " negative and positive " cover, effectively stop extraneous air and entered overflowing of flue gas in electrolyzer and in groove, reduce the excessive pollution to environment of flue gas, improved obturation effect thereby realize, reached object energy-conservation, that reduce discharging.Groove cover is sandwich design, fills the ceramic fiber paper that heat-conduction coefficient is lower and heat-insulating property is higher between interlayer, and the thermosteresis of conducting as the groove cover of heat conductor is significantly reduced, and effectively improves the heat-insulating property of whole electrolyzer.
