Source, corrodes crops and the soil that we depend on for existence, and our living environment will be faced with huge threat.So after using
Old and useless battery to carry out implementing of recycling particularly significant, not only can prevent from polluting environment, can also be to wherein useful
Composition recycled, economize on resources.
But, at present from the point of view of domestic aggregate level, Production of Secondary Lead small scale, high energy consumption, industrial technology fall behind, and adopt
Lead-acid accumulator manually or is crushed by relatively backward PROCESS FOR TREATMENT lead-acid accumulator using simple machinery,
Take out lead grid after, the wastes such as cabinet and dividing plate are stacked everywhere, do not make full use of and waste of resource, and cabinet and
Lead in small, broken bits and lead plaster is also remained it is impossible to remove, lead plaster is not easy to precipitate in shattering process, the separation to lead plaster increases on dividing plate
Add difficulty.
Content of the invention
The technical problem to be solved is to provide a kind of method simple, good in economic efficiency, and rapid subsidence is exempted to tie up
The method of shield accumulator waste diachylon.
The technical problem to be solved employs the following technical solutions to realize:
