Abstract
The utility model relates to an anode carbon block provided with a thermal insulation structure for aluminum electrolysis. The anode carbon block comprises an anode carbon block and an anode guide rod lapped with the anode carbon block through a steel claw, wherein matched thermal insulation board layers are arranged on the anode carbon block. Compared with the prior art, the anode carbon block has the advantages that the thermal insulation effect can be obviously improved by changing the thermal insulation system of the anode carbon block, the heat loss is reduced, after the anode carbon block with the structure is used, a powdery material does not need to be covered at the upper part of the anode, a great convenience is provided for pole changing operation, and the problem that a lot of alumina and smut enters the electrolytic tank during the pole changing process to influence the normal work of the electrolytic tank is avoided; as the special thermal insulation material board is small in density, thin in thickness and light in weight, the manual operation is convenient, the crust surface does not need to be cleaned, the crust blocks do not need to be fished, and the pole changing efficiency can be greatly improved; and meanwhile, the problem of serious pollution caused in the thermal insulation of the conventional powdery material is avoided.
Description
Technical field
The utility model relates to technical field of aluminum electrolysis, is specifically related to a kind of aluminum electrolysis anode carbon block of tool insulation construction.
Background technology
In the electrolysis of aluminum industry, present stage, 30%～40% of power consumption xanthenes aluminium cost, and the thermosteresis energy consumption accounts for 53% left and right of power consumption.Therefore, how to reduce thermosteresis most important to reducing ton aluminium cost.And the thermosteresis on anode carbon block top accounts for 25% left and right of total thermosteresis.So the thermosteresis that reduces anode top is a wherein very crucial link.Especially in recent years, along with the development of low temperature low voltage aluminum electrolysis technology, electrolyzer was changed to thermal-insulating type by initial heat radiating type, seemed more urgent to reducing the electrolyzer thermosteresis.Current, each aluminium electrolysis enterprise is all at the anode top a thick layer of aluminum oxide of covering and ionogen powdery material, but because the heat insulation effect of such material is also bad, is to improve heat insulation effect, can only constantly increase the thickness of material.And the sharply increase of material thickness brings again series of problems: at first, the change poles workload increases, and causes the change poles Efficiency Decreasing; Secondly, in the change poles process, a large amount of materials, dust-brand pathological material of disease enter electrolyzer, affect the steady operation of electrolyzer, cause simultaneously the bottom land precipitation to increase; Again, cause easily that the steel pawl is rubescent, thawing etc.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of aluminum electrolysis anode carbon block that can reduce thermosteresis, significantly improve the simple tool insulation construction of heat insulation effect and operation maintenance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Design a kind of aluminum electrolysis anode carbon block of tool insulation construction, comprise anode carbon block and the anode rod that overlaps by steel pawl and anode carbon block, be provided with the insulation flaggy that is complementary on described anode carbon block.
Described insulation flaggy is made by the alumina material of high temperature resistant and lightweight.This alumina material can be bought from the market, also can prepare by following steps: get AL
2O
3Powder 59～99%, SiO
20.5～40%, CaO 0.1～0.5%, MgO 0.1～0.5% contains with being mixed of binding agent of 1～2 times of aforementioned material gross weight the slurries that thing content is 300～600g/L admittedly, and then be 0.05～2.0 * 10 through thick 80～150mm, density that moulding, baking step are made
3㎏/m
3The sheet material shape, described binding agent is at least a in sodium aluminate solution, hydrogen peroxide, water soluble glue.
Also be provided with resistant to elevated temperatures inoxidzable coating at the upper surface of described anode carbon block and surrounding side.
Described inoxidzable coating is the alumina composite coating.
Above-mentioned alumina composite coating can be realized by following methods: the compo that is mixed with by the mass ratio of 1:2～3 by aluminum oxide powder, water soluble glue (by Vinyl Acetate Copolymer and/or Vinyl Acetate Copolymer and water by the formed water-sol of the volume ratio of 1:3～6) is sprayed on anode carbon block surface after fixing.
The thickness of described inoxidzable coating is 0.8～1.2mm.
The utlity model has actively useful effect:
Compared with the prior art, the utility model is by changing the heat insulation system of anode carbon block self, can significantly improve heat insulation effect, reduce thermosteresis, after using this novel texture anode carbon block, anode top does not need to cover pulverulent material again, greatly facilitate the change poles operation, and do not exist because change poles causes a large amount of aluminum oxide, dust-brand pathological material of disease to enter electrolyzer, affects the problem that electrolyzer works; And special-shaped heat preserving plate of material density is little, plate is thin, lightweight, manual operation is convenient, does not need to clear up the shell face, salvages crust block, can significantly improve change poles efficient.Avoided simultaneously the with serious pollution problem of existing pulverulent material insulation.
Description of drawings
Fig. 1 is a kind of structural representation of aluminum electrolysis anode carbon block of tool insulation construction.
In figure, 1 is anode rod, and 2 is the steel pawl, and 3 is the special-shaped heat preserving plate, and 4 is anode carbon block.
Embodiment
Further set forth the utility model below in conjunction with specific embodiment.
The aluminum electrolysis anode carbon block of 1 one kinds of tool insulation constructions of embodiment, referring to Fig. 1, comprise anode carbon block and the anode rod that overlaps by steel pawl and anode carbon block, be provided with the insulation flaggy of being made by alumina material that is complementary on described anode carbon block, also be provided with resistant to elevated temperatures alumina composite coating (1mm) at the upper surface of described anode carbon block and surrounding side.
After the anode carbon block assembling, before the By Electrolysis groove, first special-shaped heat preserving plate 3 is covered anode carbon block 4 the top, be buckled between steel pawl 2 and form the insulation flaggy and (can adopt the fast mode of inserting to be arranged on easily above anode carbon block, in case of necessity can fast dismantling except), smear high temperature resistant inoxidzable coating on the anode carbon block surface simultaneously; When changing anode scrap, first use overhead traveling crane lifting anode rod 1 that anode scrap is withdrawn from from electrolyzer; Then, replace with the new anode carbon block that assembles warming plate.After anode scrap is cooling, then the adiabator plate on anode scrap top is removed, be used for recycling.
Each concrete parameter in change above-described embodiment and the variation of component shape can form a plurality of specific embodiments, are common variation range of the present utility model, describe in detail no longer one by one at this.
