Detailed Description
As shown in fig. 1: the charged lithium battery liquid discharging device comprises a discharging battery 8, a clean water tank 11 and a discharging box 10; the method is characterized in that: a sealed room 12 is arranged above the discharge cell 8 and the clean water tank 11, the top of the sealed room 12 is sealed in a split mode through elastic rubber sheets, automatic doors are arranged on the left side and the right side of the sealed room 12, and a lifting device is arranged above the sealed room 12 and used for lifting the discharge box 10.
Tap water is put into the stirring tank 4 and injected with a certain amount, then discharge substances (such as sodium sulfate, sodium carbonate and potassium, graphite, carbon and the like which are conductive media in liquid state; strong corrosion of sodium chloride to aluminum is avoided), which are in corresponding proportion, are added, the discharge substances are fully dissolved by stirring, the solution is discharged into the discharge cell 8 after the concentration of the solution meets the discharge requirement, and the stirring tank 4 is circulated to make the discharge media fully fill the discharge cell 8.
When the discharge box 10 is used, the connecting rod and the connecting plate are lifted upwards by the hydraulic cylinder, so that the upper end of the movable rod connected with the connecting plate moves upwards, the lower end of the movable rod drives the two doors to close, and the hook device on the doors automatically triggers the limiting self-locking device, so that the doors are locked; after the charged lithium battery is placed in the discharging box 10, the charged lithium battery is moved to the battery 8 and the clean water tank 11 in sequence and then moved out of the sealed room 12; when the door needs to be opened, the unlocking hydraulic rod is used for pulling the limiting self-locking device, so that the two doors can be opened, and the lithium battery is released. Discharge chamber 10's setting had both ensured the safety of electrified lithium cell in hanging into and hanging out the in-process, and it is convenient to discharge from discharge chamber 10 for electrified lithium cell again.
Put 8 tops of battery and be sealed room 12 (adopting transparent setting), both sides are automatically opening and close according to the process needs for automatically, sealed room 12 both sides are equipped with a plurality of observation windows, and the operator can observe the battery discharge situation in putting battery 8 in real time, and sealed room 12 top intermediate position has the clearance, and the intermediate clearance uses the elastic rubber skin midsplit formula sealed, guarantees not to influence the wire rope freely to pass that lifts by crane. The sealed room 12 top is equipped with multiunit windshield 6, and the gas that electrified lithium cell produced in the discharge process in the battery 8 that discharges and discharge in-process electrolyte and organic solvent volatile gas introduce exhaust-gas treatment ware 2 through multiunit windshield 6 negative pressure at sealed room 12 top (active carbon adsorption commonly used), and the gas of production is up to standard through exhaust-gas treatment and is discharged through draught fan 1, therefore the inside little negative pressure state that forms of sealed room, prevents that waste gas from leaking.
The charged lithium batteries are uniformly loaded into the discharge box 10, the discharge box is lifted by an electric hoist 17 of the gantry crane 9 after being filled, the left automatic door 5 is automatically opened according to a corresponding instruction, the gantry crane 9 lifts the discharge box 10 into the sealed room 12, and then the automatic door 5 is closed. After the gap between the discharge box 10 and the two sides of the discharge battery 8 is adjusted by the gantry crane 9, the discharge box 10 is placed into the discharge battery 8, so that all charged lithium batteries are completely soaked by liquid discharge media, electric energy is released through the conduction of the discharge liquid media, the electric quantity of the charged lithium batteries is released to a safe range, the discharged lithium batteries are lifted out of the discharge battery 8 through the electric hoist 17 of the gantry crane 9 after discharging is completed, the liquid discharge media are suspended above the discharge battery 8, most of the liquid discharge media in the discharge box 10 and the battery crack are leached out, then the liquid discharge media are lifted into the clean water tank 11 for cleaning and soaking, after the liquid discharge media on the surface of the battery are cleaned and soaked, the discharge box is lifted out of the clean water tank 11 through the gantry crane 9, and most of water in the discharge box 10 and the battery crack is leached out of the suspension above the clean water tank 11. After the moisture in the discharge box is drained, the automatic door 5 on the right side is opened, and the discharge box 10 is hung out of the sealing room 12 and is suspended above the dewatering conveying device 13 by a certain height. The automatic lower door opening of the discharging box 10, the battery falls down under the action of gravity, certain impact is caused to the dewatering conveying device 13, the impact can remove the moisture on the surface of the battery again through vibration, and the moisture is discharged through the water leakage hole of the dewatering conveying device 13. A dewatering fan cover 14 is arranged at the climbing section of the dewatering conveying device 13; air is sent into the gas heater 15 by the high-pressure fan 16 to be heated, and then is sent into the dewatering fan housing 14 through a pipeline, and dewatering, drying and drying are carried out on discharged lithium batteries.
If the impurities in the liquid discharge medium are increased, the discharge effect is affected, and the liquid discharge medium needs to be filtered. The discharge medium is pumped out by a water pump 7, and impurities in the liquid discharge medium are filtered by a water filter 3.
And detecting whether the concentration of the discharge medium meets the discharge requirement, if the concentration needs to be adjusted, adjusting the concentration to a proper concentration through the stirring tank 4, and discharging the discharge medium into the discharge battery, wherein the discharge medium can be recycled through the circulation.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
