Description
Technical field
The present invention relates to insulation and anti-oxidation method and insulation cladding system when a kind of aluminium cell produces, belong to aluminum electricity
Solve groove insulation and anti-oxidation technology field.
Background technology
At present, existing aluminium cell in production run, commonly used on the anode of aluminium cell cover one layer by not
The mode of the bulk coating material layer of the electrolyte granular of one-size size and alumina particle mixing composition carries out being incubated and preventing
Only anode surface oxidation, this coating material layer is added mainly by overhead traveling crane and artificial making forms.Existing this employing bulk covers
The bed of material carries out being incubated and the mode of anti-oxidation, there is following problem in production and application:
1, the laying of existing coating material layer is completely by operator's experience, the became uneven of coating material layer, overburden cover
Uniformity be difficult to ensure that, thus cause be incubated uniformity poor.
2, existing aluminium oxide and electrolyte mixing mulch, when electrolysis temperature raises, particularly generating effect or groove
Condition fluctuates for a long time, is easily melted in groove, causes groove condition and self heat-insulating property to deteriorate；
3, the main component of existing coating material layer is aluminium oxide and electrolyte granular, and its mobility is preferable, the most very
It is susceptible to the rough sledding such as anodic oxidation, feed opening blocking, acute catarrhal conjunctivitis.
4, due to the effect of high temperature, make coating material layer crust harder, when change poles operates, need to employ multifunction crane special
The pneumatic tup dolly of door, uses tup to punch crust layer by force, just can extract anode scrap, add workload, waste time and energy.
5, during change poles, crust block and alumina powder are often fallen in electrolyte, cause electrolytic bath condition unstable, voltage wave
Dynamic big, cause power consumption to lose.
6, in electrolysis design process flow, in order to add mulch, the conveying of related oxidized aluminum, overhead traveling crane charging, electricity must be increased
Solve that matter is broken and the system configuration such as induction system, add system investments and systematic running cost is used.
7, in electrolysis production technological process, in order to open mulch crust when changing anode, it is necessary to configuration is electrolysed many merits
The crust breaking tool cart of energy overhead traveling crane, adds system investments and systematic running cost is used.
8, in electrolysis production material flow, the circulating load of electrolyte material is bigger, and sizable portion in circulating load
Dividing from anode-covered material, this causes recycle stock treating capacity to rise, and adds processing cost, meanwhile, and this partial electrolyte pledge
Material too increases fund and overstocks.
Owing to there are the problems referred to above, insulation and anti-oxidation mode when the most existing aluminium cell produces are the most inadequate
Preferable.
Summary of the invention
It is an object of the invention to: provide a kind of simple in construction, easy to operate, operating cost is relatively low, laborsaving, save time and
And insulation and oxidation-protective effect preferable aluminium cell are incubated when producing and anti-oxidation method and insulation cladding system, to overcome
The deficiencies in the prior art.
The present invention is achieved in that when a kind of aluminium cell of the present invention produces, insulation and anti-oxidation method are to adopt
Can the insulation cladding system of disassembly and assembly quickly and easily covering of composition is connected with steel beam column plate and heat insulating refractory material block
With covering in the groove end of aluminium cell and the position of groove sidepiece on each anode on aluminium cell, the most i.e. can replace
For the existing mulch mixed by electrolyte block and aluminium oxide, effectively it is incubated anode and prevents its surface oxidation.
When being covered on the anode on aluminium cell by insulation cladding system, first laying a layer thickness on anode is 1
～the aluminium oxide bisque of 3cm, the most again insulation cladding system is covered on the aluminium oxide bisque on anode.
Insulation cladding system is being covered on the anode on aluminium cell and is covering at the groove end of aluminium cell and groove
During the position of sidepiece, at the gap between insulation cladding system and insulation cladding system and insulation cladding system and institute
Aluminium oxide is all filled at gap at gap between the anode steel claw being enclosed within and between insulation cladding system and aluminium cell
Powder.
When a kind of aluminium cell of present invention invention produces, insulation and anti-oxidation insulation cladding system are: this device
Being connected by steel beam column plate and heat insulating refractory material block and form, it is whole that heat insulating refractory material block is connected as one by bolt and steel beam column plate
Body.
It is connected as holistic steel beam column plate above by bolt and heat insulating refractory material block is unitary solid structure.
It is provided with for being enclosed within sun being connected as above by bolt on holistic steel beam column plate and heat insulating refractory material block
Extremely go up the through hole on steel pawl.
Owing to have employed technique scheme, the present invention has abandoned aluminium oxide used in the prior art and electrolysis completely
The mode of the mixing coating material layer of matter composition.The present invention, on the basis of guaranteeing insulation and anti-oxidation function, greatly reduces structure
Crushing required for building existing coating material layer, carry, the construction investment of the system such as charging and operating cost；And dimension can be reduced
Hold the crust breaking that existing mulch produces, workload and the time of building, receive the operations such as limit by laying bricks or stones；Existing mulch can be avoided at change poles
Time crust and alumina powder fall in groove, the groove condition that causes fluctuation, thus reduce fluctuation energy consumption；Can not groove condition and bath temperature
Impact, maintains stable insulation and anti-oxidation function；Mulch circular treatment expense can be reduced and raw material fund overstocks, and
And the insulation cladding system of the present invention can reuse, therefore greatly reduce the waste of resource, effectively reduce production
Cost；And in use, the insulation cladding system of the molding made the most in batch only need to be placed in aluminium electroloysis by operator
Can complete operation on groove and on anode, therefore experience and technical merit to operator are less demanding.So, the present invention is with existing
Have technology to compare, the present invention not only have easy to operate, operating cost is low, laborsaving, save time, the advantage of work efficiency, but also
Have simple in construction, insulation and oxidation-protective effect preferably, economize on resources, less demanding to experience and the technical merit of operator,
It is easy to the advantage such as mass and standardization production.
