Abstract
Disclosed is a sealing structure for an anode baking furnace. The sealing structure aims to solve the problems that during production of an existing anode baking furnace, local temperature distribution in a side flame path is nonuniform, deformation of a flame path wall is accelerated, the service life of the furnace is shortened, difficulty of control over the pressure and temperature in the furnace is increased, fuel consumption is increased, and the qualification rate of carbon blocks obtained after being baked is reduced. The sealing structure comprises a furnace shell, a furnace face pouring block and an insulating brick. The insulating brick is arranged between the furnace shell and the furnace face pouring block, and the horizontal height of the upper end face of the insulating brick is smaller than the horizontal height of the upper end of the furnace shell and the upper end of the furnace face pouring block. The sealing structure further comprises a refractory fiber blanket and refractory castable. The refractory fiber blanket is of a U-shaped groove structure and is laid among the furnace shell, the furnace face pouring block and the insulating brick, the bottom of the U-shaped groove structure is arranged on the upper end face of the insulating brick, the inner side of the U-shaped groove structure is filled with the refractory castable, and the two outer side faces of the refractory fiber blanket are compacted on the side walls of the furnace shell and the furnace face pouring block. The sealing structure for the anode baking furnace is used for barking the carbon blocks.
Description
Technical field
The utility model relates to a kind of sealing configuration of roasting oven, is specifically related to a kind of sealing configuration for carbon anodes in aluminum electrolysis roasting oven.
Background technique
Existing anode-baking furnace is when producing, quirk in stove is to be all negative pressure state, cool air in surrounding environment can penetrate in the quirk of limit by the gap between furnace shell and boiler face castable, cause the temperature of the middle quirk of temperature in the quirk of limit generally on the low side, local temperature skewness in the quirk of limit, accelerate the distortion of flue wall, reduce the working life of stove, increased the control difficulty of furnace pressure and temperature simultaneously, not only increase the consumption of fuel, but also can reduce the up-to-standard rate of roasting after-ripening charcoal piece.
Summary of the invention
The purpose of this utility model is: a kind of sealing configuration for anode-baking furnace is provided, while producing to solve existing anode-baking furnace, cool air penetrates in the quirk of limit by the gap between furnace shell and boiler face castable, cause local temperature skewness in the quirk of limit, accelerate the distortion of flue wall, reduce the working life of stove, increased the control difficulty of furnace pressure and temperature simultaneously, not only increase the consumption of fuel, but also can reduce the problem of the up-to-standard rate of roasting after-ripening charcoal piece.
Scheme of the present utility model is as follows: a kind of sealing configuration for anode-baking furnace, comprise furnace shell, boiler face castable and insulating brick, insulating brick is arranged between furnace shell and boiler face castable, and the level height of insulating brick upper-end surface is lower than the level height of furnace shell upper end and boiler face castable upper end, described structure also comprises refractory fiber blanket and castable refractory, refractory fiber blanket becomes ' U ' shape groove structure and is laid on furnace shell, between boiler face castable and insulating brick, the bottom of described ' U ' shape groove structure is arranged on the upper-end surface of insulating brick, castable refractory is filled in ' U ' shape groove structure inner side, two outer side surfaces of the refractory fiber blanket of ' U ' shape groove structure are pressed on respectively on the sidewall of furnace shell and boiler face castable.
Between described refractory fiber blanket and castable refractory, be also provided with demarcation strip, demarcation strip 1 is adjacent to refractory fiber blanket 2 and arranges.
Described demarcation strip is galvanized steel plain sheet, and its thickness is 0.35-0.5mm.
Described refractory fiber blanket is alumina-silicate refractory fibre blanket, and its thickness is 12mm.
Described refractory fiber blanket seals respectively and between furnace shell and boiler face castable.
Insulating brick is adjacent to furnace shell setting, and the gap between insulating brick, refractory fiber blanket and boiler face castable three adopts thermal-protective material to fill.
The utility model compared with prior art, have the following advantages: the utility model is laid refractory fiber blanket between furnace shell, boiler face castable and insulating brick, and fill castable refractory in refractory fiber blanket inner side, stop that the cool air outside stove enters in the quirk of limit by the gap between furnace shell and boiler face castable, thereby reduced local temperature situation pockety in the quirk of limit; Slow down the distortion of flue wall; Increased the working life of stove; Meanwhile, reduced the control difficulty of furnace pressure and temperature; Reduced the consumption of fuel; Also can improve because of the stable of furnace inner environment the up-to-standard rate of roasting after-ripening charcoal piece.
Accompanying drawing explanation
Fig. 1 adopts the sectional drawing after sealing configuration described in the utility model between furnace shell, boiler face castable;
Fig. 2 is the partial enlarged drawing at the place of sealing configuration described in Fig. 1.
Embodiment
With reference to accompanying drawing, a kind of sealing configuration for anode-baking furnace, comprise furnace shell 4, boiler face castable 5 and insulating brick 7, insulating brick 7 is arranged between furnace shell 4 and boiler face castable 5, and the level height of insulating brick 7 upper-end surfaces is lower than the level height of furnace shell 4 upper ends and boiler face castable 5 upper ends, described structure also comprises refractory fiber blanket 2, galvanized steel plain sheet 1 and castable refractory 3, refractory fiber blanket 2 is alumina-silicate refractory fibre blanket, its thickness is 12mm, the thickness of galvanized steel plain sheet 1 is the preferred 0.35mm of 0.35-0.5mm(), 2 one-tenth ' U ' shape groove structures of refractory fiber blanket are also laid on furnace shell 4, between boiler face castable 5 and insulating brick 7, the bottom of described ' U ' shape groove structure is arranged on the upper-end surface of insulating brick 7, castable refractory 3 is filled in ' U ' shape groove structure inner side, two outer side surfaces of the refractory fiber blanket 2 of ' U ' shape groove structure are pressed on respectively on the sidewall of furnace shell 4 and boiler face castable 5.Demarcation strip 1 is arranged between refractory fiber blanket 2 and castable refractory 3, and demarcation strip 1 is adjacent to refractory fiber blanket 2 and arranges.Demarcation strip 1 makes the dimensionally stable of refractory fiber blanket 2, in the time of can also preventing from building by laying bricks or stones, the moisture content in castable refractory 3 enters in refractory fiber blanket 2, guarantees that applied at elevated temperature performance and the sealability of refractory fiber blanket 2 is unaffected, meanwhile, make refractory fiber blanket 2 be difficult for misplacing.Described refractory fiber blanket 2 seals respectively and between furnace shell 4 and boiler face castable 5, makes the sealing effect between furnace shell 4 and boiler face castable 5 better, stops cool air to enter limit quirk 6 by the gap between furnace shell 4 and boiler face castable 5.Insulating brick 7 is adjacent to furnace shell 4 and arranges, and the gap between insulating brick 7, refractory fiber blanket 2 and boiler face castable 5 threes adopts thermal-protective material 8 to fill.
