Description
Technical field
The present invention relates to lead-acid battery technical field, and in particular to a kind of accumulator pole board waste material alloy reuse method.
Background technology
Lead-acid battery has had the history of 130 years, with dependable performance, mature production technology, compared with Ni-MH battery and lithium electricity
Pond low cost and other advantages.The current electric car overwhelming majority is to use sealing-type lead-acid battery.Sealing-type lead-acid battery be by just,
Negative plate interfolded is arranged in battery case, is isolated between positive and negative pole plate with insulating barrier, when electrolyte is filled with battery
In box, electrolyte is chemically reacted with the lead on positive and negative pole plate.When battery charges, become the positive and negative two-plate of lead sulfate
On lead, the sulfuric acid components being fixed therein are discharged into electrolyte, lead and lead oxide is respectively become, make the sulphur in electrolyte
Acid concentration is continuously increased, and voltage rises, and puts aside energy；During electric discharge, lead on lead oxide and negative plate and electrolysis in positive plate
Sulfuric acid in liquid, which reacts, becomes lead sulfate, the sulfuric acid concentration in electrolyte is constantly reduced, and voltage declines so that energy drops
Low, battery externally exports energy, therefore the process that the cycle charge-discharge of battery, which is electric energy and chemical energy, constantly to be changed, final real
The storage and release of existing energy.
When accumulator pole board waste material alloy refers to that pole plate more in flakes is divided into small pieces pole plate by accumulator plate burst process
The leftover pieces metal of generation, pole plate burst produces waste material metal and accounts for the 20% of grid metal total amount, and common process is handle
Burst produces waste material metal and melts down smelting preparation, and high energy consumption, cost is high.Current lead-acid accumulator market competition is increasingly violent,
Environmental requirement more and more higher, reduction manufacturing cost and the generation for reducing waste are the top priorities of industry.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of cost is low, and energy consumption is small, it is easy to the electric power storage of practical operation
Pond pole plate waste material alloy reuse method.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of accumulator pole board waste material alloy reuse method, including following method and step：
1) pole plate more in flakes, is divided into small pieces by burst, and the pole plate waste material alloy produced in Slicing procedure is collected；
2) according to grid casting rate and alloy usage amount, pole plate waste material alloy is pressed a certain amount by positive-negative polarity classification
Contain, during in case adding grid casting lead pan, convenient quantitative input, to avoid influence adding speed from producing adding proportion mistake；
3) in grid casting cycle, a certain amount of grid metal is often added, just using grid metal as radix, is added
The pole plate waste material alloy of 8% weight, to avoid producing grid mass defect；
4) in grid casting cycle, the metal added in proportion reaches uniform mixed melting with pole plate waste material alloy, by
It is more in the oxide relative quantity of addition waste material alloy surface, the lead for removing alloy molten solution surface is salvaged after alloy melting in time
Slag.
The beneficial effects of the invention are as follows：The present invention is mixed in 8% ratio collocation pole plate waste material alloy with grid metal
Fusing, keeps alloying element composition and virgin alloy elementary composition after fusing substantially unchanged, before grid quality is ensured
Put and quantitatively add pole plate waste material ladle refining reuse in proportion, eliminate the smelting link again of pole plate waste material alloy, one is
Reduce alloy manufacture cycle cost and cost of transportation back and forth, two are the reduction of the smelting again to environment of pole plate waste material alloy
Pollution.
Brief description of the drawings
Fig. 1 is preparation process figure of the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Embodiment 1
A kind of accumulator pole board waste material alloy reuse method, in order to reduce artificial and electricity input cost and the circulation of smelting
Process lead loss, after now invention quantitatively contains pole plate waste material ALLOY CLASSIFICATION, grid metal is prepared in 8% ratio with smelting
Middle mixing carries out the grid manufacture of pole plate and applied, while for pole plate manufacturing process during grid metal is prepared in smelting
In the secondary element tin that is easily lost or calcium configured by the upper limit so that after ensureing that grid metal is mixed with 8% pole plate waste material alloy
Each alloying element composition and standard alloy composition indifference, make grid quality indifference.
Comprise the following steps that：
1) pole plate more in flakes, is divided into small pieces by burst, and the pole plate waste material alloy produced in Slicing procedure is collected；
2) according to grid casting rate and alloy usage amount, pole plate waste material alloy is pressed a certain amount by positive-negative polarity classification
Contain, during in case adding grid casting lead pan, convenient quantitative input, to avoid influence adding speed from producing adding proportion mistake；
3) in grid casting cycle, a certain amount of grid metal is often added, just using grid metal as radix, is added
The pole plate waste material alloy of 8% weight, to avoid producing grid mass defect；
4) in grid casting cycle, the metal added in proportion reaches uniform mixed melting with pole plate waste material alloy, by
It is more in the oxide relative quantity of addition waste material alloy surface, the lead for removing alloy molten solution surface is salvaged after alloy melting in time
Slag.
Accumulator pole board waste material alloy refers to the corner produced when pole plate more in flakes is divided into small pieces pole plate by burst process
Material, its main component is essentially identical to alloy lead used in grid manufacture, and simply pole plate waste material alloy surface has a small amount of lead
Oxide.After pole plate burst, pole plate waste material alloy is carried out to classify rationed, directly thrown by the 8% of virgin alloy input amount
Enter mixed melting, mixed alloying element composition will not produce deviation with respect to alloying element composition, realize that accumulator plate gives up
Expect the reuse of alloy.For logistics circulation, reduce logistics circulation transportation range, for energy input, eliminate alloy smelting
The energy input of fusing is prepared in refining；Reducing metal logistics circulation transportation range simultaneously and reducing metal smelting number of times also reduces
The diffusion and pollution of heavy metal.
