Abstract
The utility model provides a reduce aluminium cell that stops tank voltage respectively increases array cathode bus between the end negative pole bus bar that stops groove electrolysis trough and upper reaches electrolysis trough, take crimping or welded connected mode, and generating line specification and quantity are according to the distance between the negative pole bus bar and decide. The utility model is suitable for an aluminium cell of various capacity. The utility model discloses reduce the aluminium cell and stopped the generating line pressure drop during the groove, reduced the power consumption of electrolytic aluminum, increase the cathode bus tie point of adjacent electrolysis trough, further improved the security that stops groove short circuit mouth.
Description
Technical field
This utility model is related to the aluminium cell of various capacity, particularly the negative electrode bus rod of aluminium cell.
Background technology
It is known that electrolytic aluminium is a high energy consumption industry, and swash in aluminum current valency depression, production capacity surplus, the market competition
Under strong situation, domestic many aluminium electroloysis enterprises take the enterprise schema of elasticity production, will the not good enough electrolysis of production status
Groove exits, the good electrolysis bath of reserved state, so, causes and stops that groove sporadicly disperses, negative busbar non-power consumption dramatically increases
Situation.According to statistics, domestic aluminium cell stops groove pressure drop between 200 300mv, if in the case of stopping groove for a long time, will increase
Plus the power consumption of electrolytic aluminium.Currently pass through the crimping of electrolytic cell pillar bus short-circuit opening and stop groove bus, make this electrolysis bath stop groove, stop groove
Afterwards, this tank voltage 250mv, once occurred bad and lead to bias current because stopping the crimping of groove short-circuit opening point, caused other points
The phenomenon of soft bus fusing.For this reason, being badly in need of the concrete condition according to electrolysis bath, making, corresponding equipment is installed, effectively reducing and stop
Tank voltage, improves the safety that short-circuit opening runs simultaneously.
Content of the invention
The technical problems to be solved in the utility model is：There is provided a kind of reduction to stop the aluminium cell of tank voltage, reduce aluminum electricity
Solution groove stops the busbar voltage drop during groove, to reduce the power consumption of electrolytic aluminium；Increase the negative busbar junction point of adjacent cell,
Improve the safety stopping groove short-circuit opening further.
The technical solution adopted in the utility model is：A kind of reduction stops the aluminium cell of tank voltage, including stopping groove electrolysis bath
With upstream electrolysis bath, stop being provided with negative busbar between groove electrolysis bath and the termination negative electrode bus rod of upstream electrolysis bath.
Described negative busbar with stop between groove electrolysis bath and the termination negative electrode bus rod of upstream electrolysis bath using crimping or
It is weldingly connected.
Described negative busbar has multigroup, depending on its quantity and specification are according to the distance between negative electrode bus rod.
Termination negative electrode bus rod includes the negative busbar that confluxes of aluminium inlet and flue end.
This utility model can be regarded as in the termination negative electrode bus rod stopping groove electrolysis bath and upstream electrolysis bath in simple terms
Between each increase array negative busbar, take crimping or the connected mode of welding, bus specification and quantity to be confluxed mother according to negative electrode
Depending on distance between line.This utility model is applied to the aluminium cell of various capacity.
In existing electrolysis bath produces, due to the impact of a variety of extraneous factors, it is more to stop slot number amount, applies this practicality newly
Type, can design and produce interim negative busbar, is used for stopping groove on the basis of recycling aluminium scrap guide rod, stops groove electricity to reduce
Pressure and the safety improving short-circuit opening.If when stopping groove and needing to put into operation, the negative busbar of dismounting can be recycled with remelting.
In the design of electrolysis bath, typically there is 3% about spareslots, belong under normal circumstances and stop groove overhaul.Application is originally
Utility model, in new design of electrolysis cells, can design and produce a number of flexible assembly and disassembly special cathode bus, be used for stopping
Groove, to reduce the safety stopping tank voltage and improving short-circuit opening.
In sum, this utility model is either in existing electrolysis production series, or in the design of new electrolysis bath
Can be fully used, at home under the larger situation of electrolytic aluminium production capacity, there is larger application prospect.
Brief description
Fig. 1 is this utility model schematic diagram.
Specific embodiment
With reference to Figure of description, this utility model is further illustrated：
As shown in figure 1, a kind of reduction stops the aluminium cell () of tank voltage taking 230KA electrolysis bath as a example, by electrolysis bath
On the basis of the crimping of riser bus bar short-circuit opening stops groove, then conflux between negative busbar in aluminium inlet and flue end and respectively increase by 2 groups of negative electrodes
Bus, stopping tank voltage is 196mv, stops tank voltage and reduces 52mv than original technology.Calculate by running current 236KA, 1 to stop groove every
Its 295kwh that can economize on electricity.
On your aluminum 230KA electrolysis bath practice have shown that, between the termination negative electrode bus rod of two electrolysis baths, 2 groups of each crimping is female
Line, stops tank voltage and is reduced to 196mv from 248mv, reduce by 20.97% stop groove pressure drop, bus-bar compression joint point safety and stability, just run
Often.
Increase negative electrode crimping bus after, short circuit mouth for electrolytic bath can be shunted, if occur certain point crimping bad when, can
To reduce because of electric current concentrations the probability of the soft bus of the short-circuit opening that fuses.
