Description
Technical field
The utility model relates to a kind of Battery recycling equipment, particularly a kind of lead plaster of water circulation use screening sedimenting system.
Background technology
Along with social development, the continuous rising of battery use amount, has produced a large amount of old and useless batterys.Old and useless battery contains the electrolyte solutions such as a large amount of heavy metals and spent acid, salkali waste.If arbitrarily abandoned, corrupt battery can destroy our water source, corrodes crops and soil that we depend on for existence, and our living environment will be faced with huge threat.So the old and useless battery after using is carried out to the practicable very important of recycling, not only can prevent contaminated environment, can also wherein useful composition be recycled, economize on resources.
But, at present from domestic aggregate level, Production of Secondary Lead small scale, energy consumption is high, industrial technology is backward, adopts relatively backward PROCESS FOR TREATMENT lead-acid accumulator, artificial or adopt simple mechanical device that lead-acid accumulator is broken, take out after lead grid, the refuses such as plastic casing and dividing plate are stacked everywhere, do not made full use of and waste resource, and on plastic casing and dividing plate, also remaining lead in small, broken bits and lead plaster, cannot remove, easily cause secondary pollution.
In order to remove lead plaster residual on plastic casing and dividing plate, need large water gaging to rinse removing plastic casing and dividing plate.
In order to reclaim better lead plaster, there is researcher to propose lead plaster separator, notification number is the lead plaster separator that the patent documentation of CN202019040U discloses a kind of waste storage battery reclaimer, comprise the triangle liquid cylinder being obliquely installed, liquid cylinder inside has transport network to pass through, there is elevating hopper transport network lower end, and transport network upper end is provided with belt pulley, and belt pulley connects the motor that is arranged on described liquid cylinder upper end by belt.During work, the mixed liquor of lead plaster, lead powder and water joins in transport network by elevating hopper, and working surface is that cancellated transport network can filter out lead plaster send out, and the mixed liquor of lead powder and water falls into liquid cylinder, by liquid cylinder, is collected.Although this equipment is easy to use, can realizes the lead plaster in used and scrapped battery is carried out to simple separation.But lead plaster only relies on the gravity of self to collect by transport network, and lead plaster filter efficiency is low, and filter effect is not good.
By screen cloth, screen the impurity such as plastics that are still mixed with small size in the lead plaster obtaining, in order to remove this type of impurity, there is researcher to carry out water float glass process to the lead plaster of collecting and carry out separation, notification number is that the patent documentation of CN202495559U discloses a kind of waste lead acid battery reclaimer, comprise casing, its inner cavity that forms, casing is provided with charging aperture and water inlet, in this casing, be provided with agitating device and conveying worm, this cavity bottom is provided with scrapper conveyor.Equipment in above-mentioned patent documentation can separating plastic and lead plaster.
Above-mentioned utilize water float glass process to carry out the lead plaster device separated with plastics and rinse plastic casing and the dividing plate that surface is stained with lead plaster all need a large amount of water resourcess, and a large amount of lead plasters are still contained on lead plaster mixed liquor upper strata, if directly this mixed liquor is directly discharged, must cause serious environmental pollution, and cause the waste of lead plaster and water resources.
Utility model content
The utility model provides a kind of lead plaster screening sedimenting system of water circulation use, low to solve existing equipment lead plaster separative efficiency, the problem that water resource waste is serious.
A lead plaster screening sedimenting system for water circulation use, involving vibrations sieves and is positioned at described vibrating screen below for collecting the subsider of screenings, and described subsider top is provided with the first overfall;
Also comprise the sedimentation basin with inlet, described inlet is communicated with the first overfall, and the bottom of this sedimentation basin is with discharge gate, and top is with the second overfall, and described the second overfall has cistern by pipeline connection;
