[0001] The application belongs to the technical field of lithium ion battery slurry recycling, in particular to a lithium ion battery slurry recycling device and method. BACKGROUND

[0002] The waste lithium ion battery slurry is collected, including positive and negative active materials, electrolyte and conductive agent, etc. The collected waste battery slurry is filtered to remove impurities, and then the filtered slurry is soaked to dissolve and separate useful materials. The slurry after soaking is sent to a rake drying-based recycling device. In the device, the slurry is fully dried and dispersed by the stirring rake inside the device. In this process, water and organic solvents and other volatile substances are evaporated, and useful materials are recovered.

[0003] The application discloses a lithium ion battery slurry recycling device and method based on rake drying, which uniformly disperses the slurry during stirring by setting a vibration assembly inside the rotary rake assembly, preventing the slurry from adhering to the inner wall of the reaction container and the rotary rake assembly. However, the reaction container of this device is always in a fixed state, and the battery slurry accumulated on both sides of the inner wall of the reaction container becomes a dead angle area that the rake stirring mechanism cannot act on during stirring of the battery slurry. Moreover, the rake stirring mechanism has a complex structure, and frequent maintenance is required due to its low structural strength after long-term high-intensity stirring. Therefore, improvement is needed. SUMMARY

[0024] Further, the side torsion machine comprises,

[0025] A support frame is arranged on the ground;

[0026] A guide ring frame is arranged at the bottom of the outer surface of the support frame and is used for vertically erecting the outer guide ring;

[0027] A passive rotating drum is rotationally connected to the top of the inner cavity of the support frame, the front surface of the passive rotating drum is uniformly provided with a connecting torsion rod, the inner cavity of the connecting torsion rod is provided with an inner detection head, one end of the connecting torsion rod away from the passive rotating drum is fixedly connected to the outer surface of the heat preservation cylinder shell through a socket, and the inner detection head extends to the inside of the passive rotating drum.

[0028] Further, the side torsion machine further comprises,

[0029] A control motor is provided with a torsion rotating wheel on the outer surface of the output shaft, and the outer surface of the torsion rotating wheel is rollingly connected to the outer surface of the passive rotating drum;

[0031] Further, the outer guide ring comprises,

[0032] An arc-shaped guide rail is mounted on the top of the guide ring frame, and the inner wall of the arc-shaped guide rail is provided with a guide sliding rail, and the outer surface of the roller rotating sleeve is slidably connected to the inner wall of the arc-shaped guide rail through the guide sliding rail;

[0034] The beneficial effects of the present application are as follows:

[0035] 1. The device can stir the battery slurry in the stirring cylinder by rotating the rubber rake plate. Since the rubber rake plate will periodically slide during the stirring process due to the pressure control of the drainage outer disc, it prevents the slurry from adhering to the outer surface of the sliding push plate and the rubber rake plate. The plate structure combined by the sliding push plate and the rubber rake plate is relatively simple and can withstand high-strength stirring work without being easily damaged. When the guide slide rail is subjected to the resistance of the slurry, it can also be buffered by the rubber rake plate and the compression spring belt, thereby increasing the mechanism strength of the modified blade.

[0036] 2. Since the modified blades are uniformly arranged outside the through hollow tube, during the stirring work, part of the slurry will gather at both ends of the stirring cylinder. When the drainage outer disc controls the pressure, part of the air pressure will be diverted into the auxiliary drainage port, so that the wall-adhesion inner bag can periodically expand and contract, thereby pushing the slurry at both ends of the stirring cylinder to the middle, and eliminating the dead angle area of the stirring cylinder.

[0037] 3. The device stirs the slurry inside the stirring cylinder while periodically rotating the stirring cylinder by the passive rotating cylinder, so that the slurry inside the stirring cylinder also slides relative to the inner wall of the stirring cylinder under the centrifugal force, thereby preventing the slurry from forming a vortex due to the regular rotation of the rubber rake plate, which causes incomplete stirring of the slurry. The internal probe can determine whether the internal slurry is fully stirred, so as to control the stirring time according to the amount of slurry input, so as to achieve the best processing efficiency.

[0038] 4. The stirring cylinder rotates around the guide slide rail of the arc-shaped guide rail inner wall with the passive rotating cylinder. Since the roller rotating sleeve can only slide relative to the guide slide rail, the roller rotating sleeve limits the torsion motor to prevent the torsion motor from rotating. When the roller rotating sleeve slides along the inner wall of the guide slide rail, the fixed push rod machine on both sides can simultaneously push the impact inner rod to impact the shaft center of the roller rotating sleeve, thereby dispersing the slurry gathered on one side of the stirring cylinder through the vibration force, preventing the slurry from caking due to uneven stirring.

DETAILED DESCRIPTION

[0049] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0051] The holding container 1 is filled with battery slurry in the inside of the holding container 1;

[0052] The flow guide 2 is two in number, and is arranged on the upper and lower sides of the holding container 1 respectively.

[0054] The side torque machine 3 is arranged at the back of the containing container 1 and is used to drive the containing container 1 to rotate by itself.

[0055] The outer guide ring 4 is arranged outside the containing container 1.

[0056] The containing container 1 comprises,

[0057] The stirring cylinder 11,

[0058] The through hollow pipe 12, both ends of the through hollow pipe 12 extend to the outside of the axis of the stirring cylinder 11, and both ends of the inner cavity of the through hollow pipe 12 are uniformly provided with air inlet ports 18;

[0059] The modified blade 5 is uniformly arranged in the inner cavity of the through hollow pipe 12 and is used to stir the battery slurry in the stirring cylinder 11.

[0060] The torque motor 13, the top end of the output shaft of the torque motor 13 is inserted into one end of the inner wall of the through hollow pipe 12, the outer surface of the torque motor 13 is sleeved with the roller rotating sleeve 14, and the outer surface of the roller rotating sleeve 14 is embedded with a plurality of rolling balls;

[0061] The drainage outer disc 15, the axis of the inner wall of the drainage outer disc 15 is sleeved with one end of the outer surface of the through hollow pipe 12;

[0062] The closed sleeve 16, one side of the closed sleeve 16 is fixedly connected with the outer surface of the drainage outer disc 15, the other side of the closed sleeve 16 is fixedly connected with the outer surface of the stirring cylinder 11, the inner wall of the closed sleeve 16 is provided with a pressure-sensitive gasket 17, the display screen of the pressure-sensitive gasket 17 penetrates through the closed sleeve 16, and the display screen is a fluorescent screen, and the drainage outer disc 15 periodically inhales air from the outside through the internal air pump to pressurize the inside of the closed sleeve 16.

[0063] The modified blade 5 comprises,

[0064] The rubber rake plate 51, the bottom of the inner cavity of the rubber rake plate 51 is inserted with a sliding push plate 52, and the bottom end of the sliding push plate 52 is slidingly connected with the inner cavity of the through hollow pipe 12 through a cut slot;

[0065] The inner sealing rubber belt 53, the inner wall of the inner sealing rubber belt 53 is pressed against the bottom end of the sliding push plate 52, and the side edge of the inner sealing rubber belt 53 is fixedly connected with the inner wall of the through hollow pipe 12;

[0066] The compression spring belt 54, one end of the compression spring belt 54 is fixedly connected with the bottom of the sliding push plate 52, and the other end of the compression spring belt 54 is fixedly connected with the inner wall of the through hollow pipe 12.

[0067] The stirring cylinder 11 comprises,

[0068] The heat preservation cylinder shell 111 is symmetrically provided with a secondary drainage port 112 at both ends of the inner cavity of the heat preservation cylinder shell 111, and the secondary drainage port 112 is located inside the closed sleeve 16. The output pipe of the flow guide 2 is inserted into the inner cavity of the heat preservation cylinder shell 111 through the insertion port, and the plasma is drained through the through ports on the upper and lower sides of the heat preservation cylinder shell 111. The through port on the back is used for monitoring the plasma stirring work;

[0069] The wall-adhering inner bag 113 is fixedly connected to the inner wall of the heat preservation cylinder shell 111, and is used for completely covering the secondary drainage port 112. The wall-adhering inner bag 113 is an inflatable rubber belt, which completely separates the secondary drainage port 112 of the heat preservation cylinder shell 111 from the internal area.

[0070] The feeding pipe for supplying plasma is connected to the flow guide 2 above the stirring cylinder 11. At this time, the flow guide 2 above the stirring cylinder 11 continuously infuses the plasma stock solution into the inside of the stirring cylinder 11. Then, the feeding pipe of the flow guide 2 is removed, and the flow guides 2 on the upper and lower sides are blocked, so that the stirring cylinder 11 is in a relatively sealed state, and is ready for processing work.

[0071] The torsion motor 13 on both sides of the stirring cylinder 11 drives the through hollow pipe 12 inside to rotate at high speed. Since the back of the stirring cylinder 11 is limited by the side torsion motor 3, the through hollow pipe 12 drives the modified blade 5 inside to rotate relative to the stirring cylinder 11, so as to stir the plasma in the stirring cylinder 11.

[0072] When the through hollow pipe 12 rotates, the flow guide outer disc 15 on both sides also rotates. During the stirring process, the flow guide outer disc 15 first pressurizes the external gas into the inside of the closed sleeve 16. At this time, part of the gas flow enters the inside of the through hollow pipe 12 through the gas inlet through port 18, thereby increasing the pressure in the inside of the through hollow pipe 12. At this time, the inner sealing rubber belt 53 is pressed to drive the sliding push plate 52 to slide to the outside of the through hollow pipe 12, and the compression spring belt 54 is also compressed. At this time, the position of the rotating rubber rake plate 51 stirred is also constantly changing. Another part of the gas flow enters the inside of the wall-adhering inner bag 113 through the secondary drainage port 112. After the wall-adhering inner bag 113 expands, the slurry adhering to the side wall of the heat preservation cylinder shell 111 is pushed to the middle part;

[0073] When the adherent inner bag 113 expands to a certain limit, the drainage outer disc 15 starts to perform the pressure extraction work on the inner wall of the closed sleeve 16, at this time, the adherent inner bag 113 shrinks, and the sliding push plate 52 gradually shrinks into the inside of the through hollow pipe 12, through the periodic pressure change work of the drainage outer disc 15, the rubber rake plate 51 can realize the stirring and sliding motion at the same time, so that the plasma is not easily attached to the outside of the rubber rake plate 51 and the sliding push plate 52, and the adherent inner bag 113 can also push the slurry accumulated on the side wall of the stirring drum 11 to the middle area of the stirring drum 11.

[0074] When the drainage outer disc 15 performs the pressure change work, the pressure-sensitive gasket 17 located in the inside of the closed sleeve 16 can sense the pressure in the inside of the stirring drum 11, so as to realize the pressure control work, and avoid the problem of excessive pressure of the drainage outer disc 15.

[0075] Embodiment 2, please refer to Figures 1-9 The present application provides a technical solution: on the basis of embodiment 1, the side torsion machine 3 further comprises,

[0076] The control motor 33 is provided with a torsion rotating wheel 34 on the outer surface of the output shaft, and the outer surface of the torsion rotating wheel 34 is in rolling connection with the outer surface of the passive rotating cylinder 35.

[0077] The outer display screen 36 is arranged on the back of the passive rotating cylinder 35, and the inner cavity of the outer display screen 36 is connected with the inner cavity of the inner detection head 38 through wires, the inner detection head 38 can perform real-time monitoring work on the plasma stirred in the inside of the heat preservation cylinder shell 111, and transmit the picture to the outer display screen 36 for processing, so as to judge the processing progress of the plasma.

[0078] The outer guide ring 4 comprises,

[0079] The arc-shaped guide rail 41 is arranged on the top of the guide ring frame 32, and the inner wall of the arc-shaped guide rail 41 is provided with a guide sliding rail 42, and the outer surface of the roller rotating sleeve 14 is in sliding connection with the inner wall of the arc-shaped guide rail 41 through the guide sliding rail 42.

[0080] The fixed push rod machine 43 is arranged on the outer surface of the arc-shaped guide rail 41, and the shaft center of the inner wall of the fixed push rod machine 43 is in sliding connection with the impact inner rod 44, one end of the impact inner rod 44 away from the arc-shaped guide rail 41 is sleeved with a reset spring 45, and the fixed push rod machine 43 drives the impact inner rod 44 through the controllable roller in the inner cavity, so that the impact inner rod 44 relatively slides relative to the shell of the fixed push rod machine 43.

[0081] When the through hollow tube 12 stirs the slurry inside by the rubber rake plate 51, the control motor 33 drives the passive drum 35 and the connecting torsion bar 37 to twist relative to the support frame 31 by twisting the torsion wheel 34, at this time the stirring drum 11 is also driven to rotate, and when the stirring drum 11 rotates, the slurry inside also slides relative to the inner wall of the stirring drum 11 under the centrifugal action, thereby preventing the slurry from always rotating regularly with the rubber rake plate 51 to form a vortex, causing the slurry to be not completely stirred.

[0082] The stirring drum 11 rotates with the passive drum 35 around the guide sliding rail 42 of the arc-shaped guide rail 41, since the roller rotating sleeve 14 can only slide relative to the guide sliding rail 42, the roller rotating sleeve 14 limits the torsion motor 13 to prevent the torsion motor 13 from rotating, and when the roller rotating sleeve 14 slides along the inner wall of the guide sliding rail 42, the fixed push rod machine 43 on both sides can simultaneously push the impact inner rod 44 to impact the shaft center of the roller rotating sleeve 14, and the slurry collected on one side of the stirring drum 11 is dispersed by the vibration force, preventing the slurry from caking due to uneven stirring.

[0083] After the stirring work is completed, the stirring drum 11 is rotated back to the horizontal state, and then the lower flow inducer 2 is connected to the discharge pipe, at this time the upper flow inducer 2 flushes out the slurry inside, and the lower flow inducer 2 sucks away the slurry inside, and the slurry is recovered to the plasma material collecting part through the discharge pipe.

[0084] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art and related fields without creative labor should belong to the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if not specially described and limited, are implemented according to the conventional means in the art.
