Description
Technical field
The present invention relates to a kind of waste reclaimation field, be specifically related to detect at the waste and old lead acid accumulator of lead purity
Reason system.
Background technology
Along with the fast development of automobile, communication, electric power, railway and communication, automobile is used, motorcycle is used, electric motor car is used,
Railway with, military project, fixing, traction, energy storage with and the demand of uninterrupted power source lead-acid accumulator of meeting an urgent need growing,
Year consumption lead 35～400,000 tons.Lead-acid accumulator just needs to update, along with the growth of new battery requirements, waste and old lead after using a period of time
Acid accumulator quantity the most necessarily increases, and at present, annual generation all kinds of waste and old lead acid accumulators about 5000～60,000,000, weight is about
300000 tons.Waste and old lead acid accumulator, lead skim and lead mud etc. by State Environmental Protection Administration, former State Economic and Trade Commission etc. 4 ministries and commissions list state in
Family's Hazardous Waste List.The most hundreds of family of China's reviver number of the enterprise, but most enterprises small scale, yield only tens tons is extremely
Kiloton, low-level duplicate construction is serious, the recovery of waste and old lead acid accumulator, transports, stores, disposes, processes and processing regenerated deposits
In many problems.
Reviver raw material more than 85% is limited to 2～3 years from scrap battery, scrapping of accumulator in year, therefore waste lead accumulator
It it is the primary raw material of reviver.The lead battery the most indispensable power source such as motor vehicles, boats and ships.Due to burn into
The reasons such as passivation, lead battery i.e. can not be used after employing 24 years again.What China replaced every year from car, ship scraps
Lead battery quantity there are about 300,000, increases with the speed of 7% every year.The most preferably by the useful thing in waste lead storage battery
Matter recycles, and is not only related to protect country's heavy metal resources, also complies with protection environment, and the country developed a circular economy can hold
The strategy and policy of supervention exhibition.The base stock manufacturing lead battery is metallic lead and sulphuric acid.Producing and using lead battery
During, on cell panel, define lead compound by series of chemical, mainly have oxide such as lead oxide, titanium dioxide
Lead and lead salt such as lead sulfate etc..The purpose reclaimed is i.e. that through suitably processing, these metals and metallic compound are re-used as lead product
Product utilize, and in terms of comprehensive statistics, the expense of reviver is only equivalent to 1/3 from primary ore exploitation smelting expense, so having important
Meaning.
Recovery currently for lead-acid accumulator also exists multiple technologies scheme, but existing technical scheme is directly by waste and old
Leaded thing after battery crushing direct plunges into vibrosieve, the leaded thing so obtained possibly together with other metals and impurity, lead
Purity it cannot be guaranteed that, and leaded thing is not carried out careful screening, causes in the lead pig finally reclaimed containing a lot of impurity, shadow
Ring the effect recycled.
Summary of the invention
The technical problem to be solved is in the lead removal process of lead-acid accumulator, the lead pig after recycling
Containing a lot of impurity, the purity of lead it cannot be guaranteed that, present invention aim at providing the waste and old lead acid accumulator that can detect lead purity
Processing system, reaches to improve the purpose of the purity of reviver.
The present invention is achieved through the following technical solutions:
The waste and old lead acid accumulator processing system of lead purity can be detected, pure including lead-containing alloy pond, vacuum distilling segregation apparatus, lead
Degree detection device, vibrosieve, heating kettle, pulverizer, desulfurizer, ball mill, melted ingot casting device and lead plaster generate room, wherein
Lead-containing alloy pond connects has vacuum distilling segregation apparatus, vacuum distilling segregation apparatus to be separated by the lead in lead-containing alloy, and
By the purity of lead purity detecting device detection lead, if being unsatisfactory for purity requirement, then re-start vacuum distilling and separate, if meeting
Purity requirement, then put into vibrosieve by isolated lead, and vibrosieve includes two kinds of screen clothes that mesh diameter is different, and vacuum distilling divides
Be divided into the lead granule of three kinds of particle diameters through vibrosieve from the isolated lead of device, particle diameter maximum for bulky grain, bulky grain is put
Entering and carry out melted ingot casting in heating kettle, obtain lead pig and lead skim, lead pig directly recycles, and lead skim is ground through ball mill
Put into lead plaster afterwards and generate room, generate lead plaster；Particle diameter minimum for little granule, be transported in desulfurizer take off by little granule
Sulphuring treatment, is then fed into lead plaster and generates room, generate lead plaster；Particle diameter between bulky grain and little granule for middle granule, will in
Grain feeding pulverizer is ground pulverizing, and is sent to melted ingot casting device after pulverizing；
Further, described ball mill is planetary ball mill；
Further, the mesh size of described vibrosieve is 1mm and 7mm, generally from the isolated lead of vacuum distilling segregation apparatus
For the granule that size is different, the particle diameter granule more than 7mm can directly carry out melted ingot casting, and particle diameter is more than less than 7mm
It is inefficient that the granule of 1mm directly melts, and needs first to be ground carrying out melted ingot casting again, and the particle diameter granule less than 1mm holds
Easily adhering to some sulfur-bearing things, the reviver after this can cause recovery contains impurity or noxious substance, by particle diameter less than 1mm
Grain input desulfurizer is re-fed into lead plaster and generates in room and make lead plaster after carrying out desulfurization process, therefore the present invention uses the mesh diameter to be
Lead granule is screened by two kinds of screen clothes of 1mm and 7mm.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention can detect the waste and old lead acid accumulator processing system of lead purity, to lead-acid accumulator broken apart obtain contain
Lead thing carries out vacuum distilling separation, isolates other metals in lead-containing alloy, thus obtains the higher lead of purity for reclaiming
Utilizing, thus improve the purity of reviver, so, the leaded thing in waste and old lead acid accumulator separates dress by vacuum distilling
Put, then by rational technique and equipment, scrap lead can be converted into the reviver with higher value and economic worth, and
And there is the highest social value；
2, the present invention can detect the waste and old lead acid accumulator processing system of lead purity, and the lead after separating vacuum distilling carries out lead
Purity detecting, if being unsatisfactory for purity requirement, then re-starts vacuum distilling and separates, if meeting purity requirement, then by isolated
Lead puts into vibrosieve, so, it is ensured that the purity of lead, thus improves the purity of final reviver；
3, the present invention can detect the waste and old lead acid accumulator processing system of lead purity, vibrosieve therein big containing two kinds of sizes
Little screen cloth, the particle diameter that sifted branches away can affect output efficiency and the quality of last reviver, when the hole of two-layer screen cloth
When footpath is respectively 1mm, 7mm, it is possible to lead is filtered out the granule of different-grain diameter size, for the granule of different-grain diameter size, adopt
With different recovery methods, the effect after making the granule of different-grain diameter size reclaim performs to maximum, improves lead and recycle
Efficiency and reviver output capacity；
4, the present invention can detect the waste and old lead acid accumulator processing system of lead purity, uses planetary ball mill to bulky grain through adding
The lead skim produced after hot still is ground, and the Hydrocerussitum (Ceruse) after then grinding puts into lead plaster generation room and makes lead plaster, improves lead
Recycle efficiency, save production cost.
