Abstract
The utility model discloses an abnormal cathode of an aluminum electrolysis cell. The abnormal cathode is formed by high cathodes (1) and low cathodes (2), which are arranged in a staggered manner; and the low cathodes (2) are cathodes with general heights and are arranged at an aluminum outlet end (3) and a flue end (4) of the aluminum electrolysis cell. Compared with the prior art, the cathode structure of the aluminum electrolysis cell provided by the utility model is provided with the high and low cathodes which are arranged in a staggered manner, and is more advantageous in process and manufacturing amount, material use, workload for building a furnace, service life of bosses and adaptability to a method for starting the coke powder baking under the circumstance that the flow choking and energy saving effects are ensured.
Description
Technical field
The utility model relates to a kind of special-shaped cathode of aluminium cell, belongs to technical field of aluminum electrolysis.
Background technology
Over the past two years, because electric energy is nervous and the national policy guiding, China's aluminium has obtained development fast with the power-saving technology of large-sized prebaked electrolyzer, be purpose " specially-shaped cathode " technology particularly to reduce the fluctuation of flow rate of aluminium liquid and aluminium liquid minute surface, how tame at home electrolysis enterprise's test and popularization, in the specially-shaped cathode there being the principal mode of boss: uses big cathode carbon pieces sawing or press process to be shaped; Or at former cathode surface fluting and inlay the charcoal piece and be shaped; Or negative electrode is opened chamfering become special-shaped cathode.Adopt the processing and fabricating amount, material usage quantity, brickwork workload, boss life-span of above-mentioned form, to the aspects such as adaptability of coke powder baking start-up method, all exist not enough.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of can the assurance under the choked flow energy-saving effect situation, the special-shaped cathode of the aluminium cell of greater advantage is all arranged at aspects such as processing and fabricating amount, material usage quantity, brickwork workload, boss life-spans, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: highly different high negative electrodes and low negative electrode staggered arrangement form, and the low negative electrode of employing is the negative electrode of conventional height, and hang down negative electrode in the aluminium inlet and the configuration of flue end place of aluminium cell.
Lateral middle at high negative electrode offers groove.
The recess width of blanking point annex can suitably be widened, and is beneficial to the dissolving of alumina material; Can suitably increase by aluminium inlet trench digging width, conveniently to go out the aluminium operation.。
When roasting and starting, on special-shaped cathode, be equipped with coke powder, configuration can intermeshing anode block with it on special-shaped cathode.
Compared with the prior art, the low negative electrode that the utility model adopts is existing cathode size, so i.e. molding again, also need not adjust operations such as maturing temperature, yield rate can reach the highest, high negative electrode except that height dimension its making method with low as negative electrode take consistent, i.e. monolithic molding, both combinations can reach optimization on the life-span at processing and fabricating amount, material usage quantity, brickwork workload, boss, and the special-shaped cathode that constitutes also can guarantee the choked flow energy-saving effect.Offer groove in high negative electrode lateral middle, this operation is compared with existing operation can save the sawing amount of finish, has avoided the carbon materials loss simultaneously.And this just disposes and has also determined to need the high negative electrode of processing only to account for half, and this makes that also whole processing is little, and loss simultaneously is also few.Lateral middle at high negative electrode is provided with groove, is beneficial to the interior aluminium liquid of groove like this and flows; The width of groove broadens in blanking place and aluminium inlet, is beneficial to the dissolving of alumina material like this and goes out aluminium smooth and easy; Test calculating from aspects such as boss profile, material, antiscour, anticorrosive, boss and being connected of negative electrode through the applicant simultaneously, the life-span of height negative electrode choked flow boss all is better than other form and conveniently goes out aluminium operates.From roasting and starting, this structure is compared with other special-shaped cathode, and the height negative electrode can use " coke sinter " easily, and is so promptly convenient economical again.In view of the boss of height negative electrode is high negative electrode, from aspects such as boss profile, material, antiscour, anticorrosive, boss and being connected of negative electrode, the life-span of height negative electrode choked flow boss all is better than other form.For newly-built type electrolytic series: can adopt the liner design one to one of big negative electrode and anode, make the height negative electrode adapt to the profile of multifunction crane grab bucket fully, thereby convenient height cathode electrolytic cell drag for block operations.

Embodiment
Embodiment, the utility model provides a kind of height negative electrode interconnected cathode structure of aluminium cell, can guarantee under the choked flow energy-saving effect situation, in processing and fabricating amount, material usage quantity, brickwork workload, boss life-span, to the aspects such as adaptability of coke powder baking start-up method, all bigger advantage is arranged than prior art.
Concrete structure of the present utility model as shown in Figure 1, cathode construction mainly comprises high negative electrode 1 and low negative electrode 2, low negative electrode 2 is the negative electrode of former height, the distributing style of full groove negative electrode is that high negative electrode 1 and low negative electrode 2 are interconnected, but, influence following of anode to prevent the bight crust at aluminium inlet 3 and the low negative electrode 2 of flue end 4 places configuration.High negative electrode 1 and low negative electrode 2 all adopt existing conventional to do legal system.
On high negative electrode 1, be provided with groove 5, as shown in Figure 2, be beneficial to the interior aluminium liquid of aluminium cell and flow to the middle part; The trench digging width of blanking point annex can suitably be widened, and is beneficial to the dissolving of alumina material; Trench digging width by aluminium inlet 3 can suitably increase, conveniently to go out the aluminium operation.
Adopt the electrolyzer of height cathode arrangement to adopt coke sinter startup method, not corresponding for the anode and cathode profile, be transformed into the electrolyzer of height cathode arrangement behind the groove overhaul, (anode block adopts the method for cutting the anode block bottom can be processed into the profile that matches with the height negative electrode, make cathode and anode carbon piece be meshing with each other), between cathode and anode carbon piece, lay coke powder 6, as shown in Figure 3; For the electrolyzer that newly designs and produces, can in design, adopt and anode block 7 and the big one to one cathode arrangement of cathode block, anode block 7 also height is positioned on the corresponding negative electrode, make it to be meshing with each other, between lay coke powder 6, as shown in Figure 4.
