Description
Technical field
The present invention relates to be incubated when a kind of aluminium cell is produced and anti-oxidation method and insulation cladding system, belong to aluminium cell insulation and anti-oxidation technology field.
Background technology
At present; Existing aluminium cell is in production run; Generally be employed in and cover one deck on the anode of aluminium cell and be incubated and prevent the anode surface oxidation by the electrolyte granular of different grain size size with the mode that alumina particle mixes the diffusing shape coating material layer of forming, this coating material layer mainly forms by overhead traveling crane interpolation and artificial making.Existing this employing is loose, and the shape coating material layer is incubated and the mode of anti-oxidation, in producing use, exists following problem:
1, operator's experience is leaned in the laying of existing coating material layer fully, the became uneven of coating material layer, and the homogeneity of cover thickness is difficult to guarantee, thus it is relatively poor to cause being incubated homogeneity.
2, existing aluminum oxide and ionogen mixing mulch, when electrolysis temperature raise, particularly generating effect or groove condition fluctuateed for a long time, melted easily to get in the groove, caused groove condition and self heat-insulating property deterioration;
3, the staple of existing coating material layer is aluminum oxide and electrolyte granular, and it is better mobile, is easy to take place rough sledding such as anodic oxidation, feed opening card are stifled, pinkeye in use.
4, because action of high temperature makes the coating material layer crust harder, when change poles is operated, need employ the special pneumatic tup dolly of multifunction crane, use tup to punch the crust layer by force, just can extract anode scrap, increase workload, waste time and energy.
5, during change poles, the crust piece is often fallen in the electrolytic solution with alumina powder, causes the electrolytic bath condition unstable, and voltage fluctuation is big, causes power consumption loss.
6, in the electrolysis design technology flow process, in order to add mulch, must increase that relevant aluminum oxide is carried, overhead traveling crane is reinforced, ionogen is broken and system configuration such as delivery system, increase system's investment and systematic running cost usefulness.
7, in the electrolysis production technical process,, must dispose the crust breaking instrument dolly of electrolysis multi-function crane, increase system's investment and systematic running cost and used in order when changing anode, to open the mulch crust.
8, in the electrolysis production material flow, the internal circulating load of ionogen material is bigger, and in the internal circulating load sizable part from anode-covered material; This causes the recycle stock treatment capacity to rise; Increased processing costs, simultaneously, this part ionogen material has also increased fund and has overstock.
Owing to exist the problems referred to above, insulation and anti-oxidation mode when therefore existing aluminium cell is produced still are not ideal enough.
Summary of the invention
The objective of the invention is to: provide a kind of simple in structure, easy to operate, working cost is lower, laborsaving, save time and insulation and oxidation-protective effect insulation and anti-oxidation method and insulation cladding system when aluminium cell is produced preferably, to overcome the deficiency of prior art.
The present invention is achieved in that a kind of aluminium cell of the present invention is incubated when producing and anti-oxidation method is; The insulation cladding system that can dismantle quickly and easily and assemble that adopts steel panels and thermal insulation fire-resistant material block to connect to form covers on each anode on the aluminium cell and covers the groove end of aluminium cell and the position of groove sidepiece; So promptly can substitute existingly, be incubated anode effectively and prevent its surface oxidation by electrolyte block and aluminum oxide blended mulch.
In the time will being incubated cladding system and covering on the anode on the aluminium cell, on anode, laying one deck thickness earlier is the aluminum oxide bisque of 1～3cm, and then will be incubated cladding system and cover on the aluminum oxide bisque on the anode.
In the time will being incubated cladding system and covering on the anode on the aluminium cell position with groove end that covers aluminium cell and groove sidepiece, aluminum oxide powder is located all to fill in place, slit between place, slit between insulation cladding system and insulation cladding system and insulation cladding system and the anode steel jaw that is enclosed within and the slit that is incubated between cladding system and the aluminium cell.
Insulation and anti-oxidation insulation cladding system were when a kind of aluminium cell that is used for the present invention invention was produced: this device is connected to form by steel panels and thermal insulation fire-resistant material block, and the thermal insulation fire-resistant material block is connected to an integral body through bolt and steel panels.
Above-mentionedly be connected to holistic steel panels and the thermal insulation fire-resistant material block is the unitary solid structure through bolt.
Above-mentioned be connected to through bolt to be provided with on holistic steel panels and the thermal insulation fire-resistant material block be used to be enclosed within the through hole on the steel pawl on the anode.
Discarded the mode of the mixing coating material layer of aluminum oxide used in the prior art and ionogen composition fully owing to adopted technique scheme, the present invention.The present invention has significantly reduced the construction investment and the working cost of systems such as making up the needed fragmentation of existing coating material layer, conveying, feed in raw material on the basis of but protecting insulation and anti-oxidation function; And can reduce the crust breaking of keeping existing mulch production, the workload and the time of building, receiving operations such as limit by laying bricks or stones; Can avoid existing mulch when change poles, crust, the groove condition fluctuation that causes, energy consumption thereby reduction is fluctuateed with aluminum oxide powder is fallen in the groove; Stable insulation and anti-oxidation function are kept in the not influence of groove condition and groove temperature; Can reduce mulch circular treatment expense and starting material fund and overstock, and insulation cladding system of the present invention can reuse, therefore significantly reduce the waste of resource, effectively reduce production cost; And in use, the operator only need be placed in the insulation cladding system of the moulding of making in batch in advance to reach on the anode on the aluminium cell and get final product complete operation, and is therefore less demanding to operator's experience and state of the art.So; The present invention compared with prior art; That the present invention not only has is easy to operate, working cost is low, laborsaving, save time, the advantage of working efficiency, but also have simple in structure, insulation and oxidation-protective effect better, economize on resources, less demanding to operator's experience and state of the art, be convenient to advantages such as mass and standardization production.
