The lining device of the pre-culture anode aluminum electrolytic cell provided by the utility model effectively lowers the production cost of electrolytic aluminum, also prolongs the service life of the electrolytic cell, meanwhile reduces the energy source consumption, and becomes the best combined point of environment protection.
Description
Technical field
The utility model relates to electrolyzer, is specially a kind of inner lining apparatus of pre-training anode aluminium cell.
Background technology
At present, aluminium is output maximum, purposes non-ferrous metal the most widely, and for a long time, metallic aluminium all adopts fused salt electrolysis process production.Aluminium electrolytic industry is important base mateiral industry, but also is one of main high energy-consuming industry simultaneously.China is faced with huge energy-saving and emission-reduction pressure as the whole world maximum primary aluminum producing country and country of consumption.
The energy balance of electrolyzer refers in the unit time receipts of energy in the electrolyzer, equates.When the energy of electrolyzer input equaled the energy of electrolyzer expenditure, the energy of electrolyzer just can be kept equilibrium state.The heat that dispersed heat and steel pawl were taken away when electrolyzer energy expenditure comprised energy that electrolytic reaction consumes, heat that aluminium liquid is taken away, heat that gas is taken away, change poles and electrolyzer be the heat that loses by convection current, radiation and conduction of environment towards periphery.And present domestic electrolyzer is the main mode of electrolytic aluminum, but because the inner lining structure of existing electrolyzer is still waiting perfect at the internal stress design aspect.
The utility model content
The technical problem that the utility model solves is to provide a kind of inner lining apparatus of pre-training anode aluminium cell, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of inner lining apparatus of anode aluminium cell, comprise side wall carbon block layer, aluminium oxide granule granulosa, cement layer, anode graphite layer, impervious barrier, bottom insulating brick and ceramic plate, described anode graphite layer is positioned at the middle part of this device, the below of described anode graphite layer is cast with described cement layer, the below of described cement layer is impervious barrier, bottom insulating brick and ceramic plate successively, the outside of this device is described aluminium oxide granule granulosa, and the inboard of described aluminium oxide granule granulosa is the side wall carbon block layer.
In the utility model, the both sides of described cement layer are provided with the sidepiece insulating brick.
Beneficial effect
The utility model has effectively reduced the production cost of electrolytic aluminum and has increased the life-span of electrolyzer, has reduced energy consumption simultaneously, becomes the best joint of environment protection.
Description of drawings
Fig. 1 is a kind of inner lining apparatus synoptic diagram of pre-training anode aluminium cell.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of inner lining apparatus of pre-training anode aluminium cell, comprise side wall carbon block layer 1, aluminium oxide granule granulosa 2, cement layer 4, anode graphite layer 5, impervious barrier 6, bottom insulating brick 7 and ceramic plate 8, described anode graphite layer 5 is positioned at the middle part of this device, the below of described anode graphite layer 5 is cast with described cement layer 4, the below of described cement layer 4 is impervious barrier 6, bottom insulating brick 7 and ceramic plate 8 successively, the outside of this device is described aluminium oxide granule granulosa 2, and the inboard of described aluminium oxide granule granulosa 2 is side wall carbon block layer 1.
In the utility model, the both sides of described cement layer 4 are provided with sidepiece insulating brick 3.
In recent years, it is 30%, 50%, 75% high graphite and full graphite matter carbon piece that China successfully develops content of graphite, and the overall quality level significantly promotes, and along with content of graphite increases, rate of expansion reduces, and resistivity diminishes, and abrasion index increases, and permeability resistance improves.Content of graphite is more high, and intensity and wear resistance lower.Permeability resistance, abrasion index are the important physical and chemical indexs of cell life, and resistivity is an important physical and chemical index of energy consumption.Through overall target relatively, selecting content of graphite for use is 30% high graphite bottom charcoal piece, can effectively cut down the consumption of energy, and prolongs cell life.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
