TECHNICAL FIELD

[0001] The present application relates to the technical field of dry processing equipment, in particular to a lithium battery slice post pole piece drying and scattering device. BACKGROUND

[0002] The waste lithium battery contains heavy metals (lead, cadmium) and harmful electrolyte, and random disposal will pollute the soil and water source and destroy the ecological system. Recycling through standardized treatment (such as hydrometallurgy, physical disassembly) can avoid harmful substance leakage and reduce environmental risk. The current core bottleneck of the waste battery recycling industry is the battery cell disassembly link. The traditional battery cell disassembly process has many problems and hidden dangers, such as safety hazards: mechanical collision easily causes high-nickel positive electrode explosion, accident rate > 10%; material mixing: physical crushing leads to copper-aluminum foil, separator and black powder mixing with each other, and the purity of black powder is only 85%-90%; pollution out of control: electrolyte volatilization produces HF acid mist.

[0003] For example, a dry processing equipment with publication number CN206787197U includes a bottom plate, a support, a box, a bearing seat, a right helical thread, a handle, a slide rail, a first sliding block, a first connecting rod, a second sliding block, a drying frame, a screen, a second connecting rod, etc. The bottom plate is symmetrically welded with supports on the right side of the top, and the box is connected to the top of the two supports by bolts. The top of the left wall of the box is provided with a first rotating shaft. The pole piece can be dried by the first and second heating plates. Then the worker can move the drying frame up and down by shaking the handle, achieving the effect of fast drying speed and convenient storage and retrieval.

[0004] However, when the lithium battery cell slice is broken and dried, the hot air introduced for electrolyte evaporation treatment cannot fully contact the partially overlapped battery cell slices, resulting in uneven electrolyte evaporation treatment, reduced electrolyte recovery efficiency and drying effect of the battery cell slices. In addition, when the electrolyte in the separated waste gas is condensed and recovered, the temperature of the condenser tube will rise as the waste gas is input, and the condenser tube needs to be cooled in time to maintain the full condensation and recovery of the electrolyte in the waste gas. SUMMARY

[0024] Preferably, the output end of the servo motor is fixedly installed with an electromagnetic cylinder, the electromagnetic cylinder is located between the screen one and the screen two, and the bottom of the screen one and the screen two is fixedly installed with a vibrating motor.

[0025] By adopting the above technical scheme, the servo motor drives the electromagnetic cylinder to rotate, the electromagnetic cylinder has magnetism after being electrified, and the copper-aluminum foil metal fragments with a diameter greater than 30 purposes are directionally recycled by the electromagnetic cylinder.

[0026] Compared with the prior art, the beneficial effects of the present application are: by setting the drying assembly, when crushing, the two vertical plates moving in a straight line can assist in dispersing the battery cell slices, and the distance from the bottom of the vertical plate gradually decreases from the middle to the sides, which can spread the battery cell slices accumulated in the middle, thereby reducing the stacking of the battery cell slices, facilitating the crushing of the battery cell slices by the crushing tooth rollers, improving the crushing efficiency, and facilitating the full contact of the hot air with the electrolyte, thereby facilitating the rapid evaporation of the electrolyte, and the cooperation of the vertical plate and the baffle facilitates the tilting and deflection of the baffle at intervals, thereby blocking the hot air at intervals, thereby prolonging the contact time of the hot air with the battery cell slices, improving the drying treatment effect, and facilitating the rapid and efficient drying.

[0027] 1、 By setting the drying assembly, the battery cell slices are conveyed to the position of the feed inlet by the conveying belt, the battery cell slices fall between the two crushing tooth rollers, the operator starts the driving motor to work, the driving motor drives the crushing tooth rollers to rotate, the two crushing tooth rollers crush the battery cell slices, at the same time, the hot air pipe is connected with the external hot air generating device, the inert gas is introduced for protection, the hot air rapidly evaporates the electrolyte, and the linear guide rail one on the two sides drives the moving plate and the push rod to move, the push rod drives the fixed frame and the vertical plate to move horizontally, the fixed frame drives the top plate to move horizontally in a straight line, when the vertical plate moves, it is pressed by the inclined surface of the inclined plate, so that when the vertical plate approaches the side box, the vertical height decreases, the inner top surface of the square groove compresses the spring one, thereby facilitating the spreading of the battery cell slices accumulated in the middle to the two sides, thereby reducing the stacking of the battery cell slices, and reducing the situation that the battery cell slices are pressed to the middle when moving in a straight line, and when the top plate moves towards the side box, the baffle is also pressed, the baffle drives the shaft to rotate, the baffle is deflected to block the hot air at intervals, facilitating the full contact of the hot air with the battery cell slices, thereby improving the drying and dispersing effect of the battery cell slices;

[0028] 2. After crushing, the material is initially sorted by screen one with a mesh size of 30 mesh and screen two with a mesh size of 40 mesh. Vibration motors are installed at the bottom of both screen one and screen two. The servo motor drives the electromagnetic cylinder to rotate. When the electromagnetic cylinder is energized, it becomes magnetic. Copper and aluminum foil metal fragments larger than 30 mesh are directionally recovered by the electromagnetic cylinder, while black powder and diaphragm smaller than 40 mesh enter the air classifier through the conveyor belt for easy air separation. The separated dust-containing waste gas enters the condensation box through the connecting pipe for the condensation and recovery of the electrolyte.

[0029] 3. By setting up a condensation assembly, the exhaust gas enters the condenser pipe through the connecting pipe. The water injection pipe is connected to the external pressurized water pipe, and the water is sprayed through the spray nozzle. The linear guide rail II drives the moving seat to move, which facilitates linear reciprocating spraying. When the spray nozzle sprays the strip plate, the strip plate rotates downward due to the impact. The strip plate compresses the spring II, and the strip plate drives the rotating ring and inner ring to rotate. The inner ring drives the rotating rod to rotate. The rotation of the rotating rod will squeeze the adjusting plate. The adjusting plate stretches the spring extension rod, so that the two adjusting plates are brought closer to each other. When the strip plate deflects downward to the lowest end, the two adjusting plates will close together. At this time, only the upper and lower parts of the adjusting plate are available for ventilation, so that the remaining cross-sectional area of ​​the flow is reduced to a sufficiently small size. Even if the flow rate is increased due to the reduced cross-sectional area, the gas will not flow away quickly. This facilitates the rapid and sufficient condensation of the exhaust gas, helps to improve the condensation efficiency of the exhaust gas, and reduces the situation where the condensation efficiency decreases due to the increase in temperature.

[0051] ​One end of the rotating shaft 414 is rotatably connected to the back side of the inner wall of the processing box 1. A torsion spring 416 is sleeved on the outer side of the rotating shaft 414. The two ends of the torsion spring 416 are fixedly connected to the baffle 415 and the inner wall of the processing box 1, respectively. The baffles 415 are arranged at equal intervals and there are no less than three. When the top plate 412 presses one of the baffles 415, the other baffles 415 will not deflect, thus maintaining the circulation of hot air in other positions.

[0052] A side door is fixedly installed on the lower side of the other side of the processing box 1. When the side door is opened, it can connect with the inlet of the conveyor belt section 5 to facilitate the conveying of the screened black powder and diaphragm material.
