Abstract
The utility model discloses a anode oxidation preventing device for a prebaked anode electrolyzer, which comprises an anode carbon block (1) and a side edge (2) of the electrolyzer, wherein an anode baffle plate (3) is arranged between the anode carbon block (1) and the side edge (2) of the electrolyzer, the anode baffle plate (3) is placed on a housing (4) formed by aluminum electrolyte solution, and a thermal insulation material (5) is arranged between the anode baffle plate (3) and the anode carbon block (1). As the side part of the anode carbon block is blocked by the anode baffle plate, the material can not be scattered to a radiating ribbon on the side edge of the electrolyzer when blanking the thermal insulation material and shaping, and a slope does not need to be piled up for retracting the radiating ribbon, thereby reducing the workload and the working time of the traditional anode exchange operation, reducing the process steps and reducing the labor intensity of working. In addition, the width of the natural radiating ribbon is widened in comparison with the prior art due to the absence of the built slope; and simultaneously, the furnace surface formed by applying the baffle plate is regular and orderly, thereby being conductive to the development of a lateral furnace wall.
Description
Technical field
The utility model relates to a kind of prebaked-anode type cell that is used for and prevents anodised device, belongs to the aluminium cell technical field.
Background technology
When in the industrial aluminum electrolysis production, changing the anode operation; when newly changing on the anode behind the groove in order to protect new anode not oxidized; simultaneously in order to reduce thermosteresis; need on anode, add one deck insulation material; because anode side is a vertical surface; can't directly up add insulation material; piece material on the boiler face need be pushed away toward anode side walls; build into the anode outer side edges along forming about 60 ° slope with the boiler face housing; command overhead traveling crane between the two new utmost points, to add then and extremely go up insulation material; carrying out shaping with the aluminium rake again makes insulation material be layered on anode surface uniformly; at last receive out the wide heat-radiation belt of 10-15cm, to guarantee the regular of heat radiation of electrolysis trough side part and stove group of limit portion along the sidepiece edge of electrolyzer.
If it is bad that this operation is operated, not only can influence the anti-oxidation work of anode side, and can allow the sidepiece edge heat radiation of electrolyzer bad, can make sideways furnace wall melt attenuation, make electrolyzer can't form type in the good burner hearth.Can't effectively stop electric current to pass through, form wasting of electric current, also strengthen the thermosteresis of electrolyzer simultaneously, reduce the current efficiency of electrolysis production from sidepiece.In addition because sidepiece can't form good stove group, cause the side wall carbon block of electrolyzer directly to contact with aluminium liquid and suffer erosion with high-temperature electrolysis matter, not only have influence on the primary aluminum quality of electrolyzer, and can cause the sidepiece breakage, finally cause serious bakie, reduced the working life of electrolyzer, this change poles work simultaneously is loaded down with trivial details, time-consuming.
The utility model content
The technical problems to be solved in the utility model is: a kind of workload and working hour that reduces traditional change poles operation is provided, the prebaked-anode type cell that is used for of anode oxidation-protective effect prevents anodised device behind the raising change poles, can overcome the deficiencies in the prior art.
The technical solution of the utility model: it comprises the sidepiece edge of anode carbon block and electrolyzer, between anode carbon block and electrolyzer sidepiece edge, be provided with anode baffle, anode baffle is placed on the housing of aluminium electrolyte liquid formation, is provided with insulation material between anode baffle and anode carbon block.
Described anode baffle is made of triangular supports and panel, and panel is relative with anode carbon block, and support contacts with the sidepiece edge of electrolyzer.
The panel of anode baffle and the angle of housing are 70～100 °.
The panel of anode baffle and the angle of housing are 90 °.
The distance at the sidepiece edge of panel and electrolyzer is 10～15cm.
Compared with the prior art, the utility model is by placing anode baffle between anode carbon block and electrolyzer sidepiece edge, like this when the change poles operation proceeds to 5.18 steps of " the 230KA prebaked-anode type cell changes the anode operation rules ", the anode baffle device is put into, the panel of anode baffle is in the face of anode carbon block, pinch of a spot of block material is filled in the space, bottom between anode baffle and the anode carbon block sidepiece, commands overhead traveling crane to add between the two poles of the earth then and extremely goes up insulation material, then harrows shaping with aluminium.Because the anode carbon block sidepiece has anode baffle to block, just not having the heat-radiation belt of material to the sidepiece edge of electrolyzer when following insulation material and shaping is scattered, just do not need to pile up the slope, receive heat-radiation belt at electrolyzer sidepiece edge " this operation; reduce the workload and the working hour of traditional change poles operation; reduce operation, alleviate the labour intensity of work.In addition, owing to the slope that has not had to build, the width of natural heat dissipation band is also widened than before to some extent; The boiler face of using baffle plate formation simultaneously is regular in order, helps the growth of sideways furnace wall.Can not only form type in the good burner hearth, but also effectively protect sidewall carbon brick not to be subjected to the erosion of high-temperature electrolysis matter and aluminium liquid, reach the purpose that improves current efficiency and prolong bath life.Anode baffle is made of triangular supports and panel, and panel is relative with anode carbon block, and is so not only simple in structure, safe in utilization, light, and has good stability.

Embodiment
Embodiment: as shown in Figure 1, the anode carbon block 1 of electrolyzer is fixed in the aluminium cell by steel pawl 6, after newly changing anode carbon block 1, for preventing anode carbon block 1 oxidation covering and heat insulating material 5 on anode carbon block, insulation material 5 is deposited on the housing 4 of aluminium electrolyte liquid formation, the utility model is the stacking that makes things convenient for insulation material 5, between anode carbon block 1 and electrolyzer sidepiece edge 2, place anode baffle 3, anode baffle 3 constitutes (as shown in Figure 2) by triangular supports 7 and panel 8, support 7 adopts the reinforcing bar assembly welding to form, panel 8 adopts steel plate, panel 8 is welded on the support 7, when placing anode baffle 3, panel 8 is relative with the sidepiece of anode carbon block 1, and support 7 contacts with the sidepiece edge 2 of electrolyzer, and the panel 8 of anode baffle 3 is 70～100 ° with the angle of housing 4, preferred panel 8 is vertical with housing 4, the distance location 10～15cm (heat-radiation belt width) between the sidepiece edge 2 of panel 8 and electrolyzer.
The using method of this device, like this when the change poles operation proceeds to 5.18 steps of " the 230KA prebaked-anode type cell changes the anode operation rules ", anode baffle 3 is put into, the panel 8 of anode baffle 3 is in the face of anode carbon block 1, pinch a spot of insulation material 5 is filled in the space, bottom between anode baffle 3 and anode carbon block 1 sidepiece, command overhead traveling crane between the two poles of the earth, to add then and extremely go up insulation material 5, then harrow shaping with aluminium.Because anode carbon block 1 sidepiece has anode baffle 3 to block, just not having the heat-radiation belt of material to the sidepiece edge 2 of electrolyzer when following insulation material and shaping is scattered, just do not need to pile up the slope, receive this operation of heat-radiation belt at 2 places, electrolyzer sidepiece edge, reduce the workload and the working hour of traditional change poles operation, reduce operation, alleviate the labour intensity of work.
