Description
Technical field
The utility model relates to a kind of Battery recycling equipment, particularly a kind of secondary 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 improve the separating effect of lead plaster and plastics, improve the purity of collected lead plaster, general method is by aperture plate, to carry out the screening of lead plaster, remove larger plastics and the lead grid of volume, but in the lead plaster that screening obtains, be still mixed with the impurity such as plastics of small size, 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.
Lead plaster needs the time in infall process, and the sedimentation time is longer, and effect of settling is better, but the long efficiency that can reduce lead plaster separation of sedimentation time reduces production efficiency, affects economic benefit.Sedimentation time, a large amount of lead plasters were still contained on lead plaster mixed liquor upper strata more in short-term, if directly this mixed liquor is directly discharged, must cause serious environmental pollution, and cause the waste of lead plaster.
Utility model content
The utility model provides a kind of secondary sedimenting system, low to solve existing apparatus settling efficiency, and the large problem of blowdown flow rate.
A secondary sedimenting system, the first overfall that comprises subsider and be arranged on subsider top, also comprises the sedimentation basin of sidewall band inlet, and 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.
During use, the larger lead plaster rapid subsidence of lead plaster mixed liquor proportion within a short period of time in subsider is to subsider bottom, the lead plaster that part proportion is less still swims in the mixed liquor on upper strata, now continue to feed in raw material in subsider, upper strata mixed liquor overflows the first overfall and enters sedimentation basin by inlet, carries out secondary sedimentation in sedimentation basin.By above setting, can strengthen the inlet amount of subsider, make heavy lead plaster rapid subsidence and collection, and the less lead plaster of proportion enters sedimentation basin, carry out secondary sedimentation, thereby effectively improve the settling efficiency of lead plaster.
In order to improve effect of settling, preferred, described discharge gate is arranged on the centre of bottom, described bottom is also provided with the conveying ribbon to discharge gate feeding, described conveying ribbon is coaxial mounted two parts, is in respectively discharge gate both sides, and two parts carry the mass transport direction of ribbon relative.The discharge gate more than arranging and conveying ribbon, in the middle of the lead plaster both sides that are deposited in bottom are delivered to, transport simultaneously both sides, effectively improves and transport efficiency.
In order to improve the purity of the lead plaster of collection, preferred, between the first overfall of subsider and the inlet of sedimentation basin, be provided with lautertuns.In lautertuns, the plastics that the mixed liquor overflowing from the first overfall, shape is larger and metallic particles are filtered, improve lead plaster purity in the mixed liquor that enters sedimentation basin.
For lautertuns convenient for cleaning, preferred, the inside of described lautertuns is provided with movable filter plate of pegging graft.Movable the pegging graft of described filter plate arranges, and when cleaning lautertuns, filter plate can be pulled down to cleaning, is convenient to periodic cleaning lautertuns.
For the mixed liquor that makes to overflow from the first overfall enters sedimentation basin fast, preferred, the bottom surface of described lautertuns is that lower gradually along liquid flow direction on ，Gai inclined plane, inclined plane.By above setting, mixed liquor flows out along inclined plane fast filtering from overfall outflow enters lautertuns.
In order to improve the collecting effect of lead plaster, preferred, described inlet is positioned at the middle part of sedimentation basin.Lead plaster mixed liquor enters sedimentation basin from being arranged on the inlet at the middle part of sedimentation basin, makes lead plaster rapid subsidence that proportion is larger to sedimentation basin bottom, effectively improves the settling efficiency of lead plaster in mixed liquor.
In order to improve the lead plaster rate of recovery, reduce the dustiness of waste discharge, preferred, in described sedimentation basin, be provided with the screen pack that covers the second overfall.Mixed liquor is discharged from the second overfall by screen pack again, and in the mixed liquor that makes to overflow, lead plaster content reduces greatly.
The beneficial effects of the utility model:
Secondary sedimenting system of the present utility model, by the first overfall of subsider is communicated to sedimentation basin, lead plaster mixed liquor is carried out to secondary settlement, thereby can strengthen the inlet amount of subsider, make heavy lead plaster rapid subsidence and collection, and the less lead plaster of proportion enters sedimentation basin, carry out secondary sedimentation, effectively improve the settling efficiency of lead plaster.
