Description
Technical field
The present invention relates to the manufacture method of battery polar plate, be specifically related to a kind of method of utilizing the new battery polar plate of active clay work in the waste battery.
Background technology
Storage battery (also claiming storage battery) is a kind of electric energy to be changed into chemical energy and savings, again chemical energy changed into electric energy during use and releases by external circuit, but the low-voltage dc power supply that repetitive cycling is used.It has convenient, the safe and reliable advantage of power supply, thereby be widely used in motor vehicle, ships such as automobile, motorcycle, electric bicycle, submarine as indispensable power source, and elevator, computer, mine lamp, instrument etc., wherein acid cell (also claiming lead accumulator) uses the most extensive.Acid cell is mainly made the active material of positive and negative pole plate by dilution heat of sulfuric acid, brown lead oxide and pure lead.Making battery polar plate at present is to take the metallic lead as the black powder of raw material system, is raw material system battery polar plate with black powder again, and therefore plumbous use amount is bigger.The annual lead amount of producing in countries in the world is used as the raw material that storage battery is produced more than 80%, current especially social, automobile, motorcycle, electric motor car enter huge numbers of families, and the storage battery use amount is advanced by leaps and bounds, and plumbous consumption linearly rises.Therefore, the lead that reclaims in the old storage battery also shows important day.
Active mud and lead salt that conventional method reclaims in the old storage battery are to make metallic lead earlier, or utilize after making red lead, yellow lead again.Because traditional handicraft all adopts the active mud of high-temperature process to reclaim metallic lead, require temperature more than 800 ℃, even up to 1300 ℃, make the fusing of lead salt and metallic lead even become steam, and lead can not be degraded, the lead of loss becomes steam or lead salt and scatters marinely in air, soil and river, rivers and lakes, certainly will cause serious environmental to pollute; Accumulation simultaneously in vivo, danger such as the pollution that causes may cause poisoning, carcinogenic; And conventional method reclaims active mud in the old storage battery and has the defective that loss is big, the rate of recovery is lower, and wherein the Qian rate of recovery is generally 60%～70%, the highlyest also is no more than 85%.
Summary of the invention
At the prior art above shortcomings, the purpose of this invention is to provide and a kind ofly reduce environmental pollution, improve the plumbous rate of recovery and reduce cost, utilize the active clay method of making battery polar plate in the waste battery.
The object of the present invention is achieved like this: a kind of manufacture method of battery polar plate may further comprise the steps:
1) cleans, decomposes: the waste battery that reclaims is cleaned, dries with running water, be decomposed into shell, barrier film, joint, pole plate and active mud;
2) reclaim lead: the active mud that from pole plate and active mud, decomposes grid and powdery;
3) system pole plate cream mud: with active mud with the pure water washes clean after, dehydration, adjust oxidizability with the active mud in the pole plate, the controlled oxidation lead content is not less than 75%; The adding dilute sulfuric acid mixes produces cream mud;
4) system screen:, under 300 ℃～320 ℃ conditions, melt with joint, grid washing, the oven dry of reclaiming; Adjusting lead, antimony ratio meet country or company standard, and casting is made grid;
5) system pole plate: on grid, apply pole plate cream mud, natural air drying, curing molding;
6) change into: after the curing, charge and discharge get final product again.
Compared to existing technology, the present invention has following advantage:
1, the present invention handles active mud in normal temperature or low temperature, removes the pollutants such as impurity in the deactivation mud, improves about 15% than the high-recovery 85% of traditional handicraft, has reduced loss, eliminates the pollution to environment, makes the lead salt and the metallic lead rate of recovery near 100%;
2, in processing procedure, adopt the active mud of closed continuous processing to be used to produce battery polar plate, environment is not caused any pollution;
3, the present invention directly makes pole plate to the lead salt in the recovery storage battery after purification and impurity removal matter, makes metallic lead no longer earlier, by the black powder of metallic lead system, makes pole plate by black powder again, thereby shortened process greatly.Compare traditional handicraft and simplified flow process, shortened the production cycle;
4, save the equipment investment expense more than 50%, energy efficient about 50% effectively reduces cost.
The invention will be further described below in conjunction with embodiment.
Embodiment
The manufacture method of battery polar plate of the present invention is specially a kind of method of utilizing the new battery polar plate of active clay work in the waste battery, may further comprise the steps:
1, cleans, decomposes: the waste battery that reclaims is cleaned, dries with running water, adopt craft or mechanical means to be decomposed into plastic casing, barrier film, joint, pole plate and active mud;
2, reclaim lead: the active mud that from pole plate and active mud, decomposes grid and powdery;
3, system pole plate cream mud: with active mud with the pure water washes clean after, dehydration, under 100 ℃～120 ℃ conditions, dry; Adjust oxidizability with the active mud in the pole plate, levelling lead oxide (PbO) content is not less than 75%: promptly during lead oxide (PbO) content excess, add the active mud (lead sponge) of negative plate; Lead oxide (PbO) adds the active mud of positive plate when containing quantity not sufficient.Add again proportion for (1.15-1.35) as 1.2 dilute sulfuric acid, the addition of dilute sulfuric acid is that 15%, 18%, 22% or 26% of cream mud weight mixes and produces cream mud;
4, system screen:, under 300 ℃～320 ℃ conditions, melt with joint, grid washing, the oven dry of reclaiming; According to company standard adjusting lead (Pb) and antimony (Sb) ratio, casting is made grid;
5, system pole plate: on grid, apply pole plate cream mud, natural air drying, curing molding;
6, change into: after the curing, charge and discharge again change into 18～30 hours time to get final product.
Adopt said method to get 3.3 tons of waste batteries, recovery can get 1 ton of active mud, 20,000 (14 * 12cm2) on the cream mud pole plate that can make.Equally, can make 20,000 cream mud with 1 ton of metallic lead, 10000 yuan of 1 ton of metallic leads, 1 ton of active mud cost is 5500 yuan.Therefore, economic benefit is considerable.
The present invention directly uses the active mud of waste battery through washing, purification, directly is used in the cream mud of making pole plate.Be different from fully and traditional reclaim metallic lead, make black powder by metallic lead again from lead salt (active mud), and then with the method for deceiving powder system pole plate cream mud.Thereby simplified technology greatly, and reduced a large amount of equipment investments, saved expenses such as man-hour and water power.
Adopt the present invention, the plumbous rate of recovery can reach more than 99%, and is higher more than 15% than the rate of recovery (being up to 85%) of former recovery technology; And can the former method of loss-rate reduce more than 50%; And environment is not had any pollution, and the whole operation operation process is to carry out in the totally enclosed circulation process, and three-waste free discharge has thoroughly changed the shortcoming of the contaminated environment that former recovery technology exists.Can be widely used in storage battery factory and useless storage battery and recycle unit.
