[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a soaking device for treating lithium battery waste residue, which has the following beneficial effects: The immersion device for treating lithium battery waste residue can form a centripetal vortex flow when the inclined rotating shaft and spiral blades rotate, and the waste residue deposited at the bottom is brought to the center position, further promoting mixing. The vortex flow helps to reduce the deposition of waste residue at the bottom and keep the waste residue in the solution evenly distributed, avoiding the traditional method in which the waste residue is easily deposited at the bottom, resulting in uneven mixing and insufficient reaction, and forming a mixing dead corner, affecting the overall treatment effect.

[0016] The soaking device for treating lithium battery waste residue drives the hexagonal sleeve to rotate on the hexagonal fixed column by tilting the rotating shaft seat, and finally enables multiple rotating shafts and spiral blades thereon to achieve planetary motion of revolution and rotation at the same time. Through the planetary motion (revolution plus rotation) of the spiral blades, the lithium battery waste residue can be more evenly mixed in the soaking solution, ensuring that the waste residue is fully in contact with the solution, improving the reaction efficiency, and avoiding the problem of uneven mixing of the waste residue and the solution in the traditional method, resulting in partial waste residue failing to react fully and reducing the overall treatment efficiency.

[0017] The soaking device for treating lithium battery waste residue has a rubber slapper that hits the outer surface of the soaking bin under the force of the impact rod when the impact rod hits downward, thereby generating a certain degree of shock force, so that the lithium battery waste residue in the soaking bin can be evenly dispersed, and the mixed impurities therein can float on the surface, so that the separation efficiency of the materials in the lithium battery waste residue can be further improved. The impact of the impact rod and the rubber slapper generates a shock force on the soaking bin, so that the waste residue is evenly dispersed, which helps the impurities to float to the surface and improves the separation efficiency. After the waste residue is evenly dispersed, the mixed impurities are more likely to float to the surface, which is convenient for subsequent separation treatment, improves the separation efficiency of the materials, and avoids the problem that in the traditional method, the waste residue and impurities are mixed together, the separation is not thorough, resulting in the loss of useful components and the reduction of the recovery rate.

[0018] The soaking device for treating lithium battery waste residue has a counterweight bar, a rubber sleeve and a rubber slap plate. Due to the gravity of the counterweight bar, the rubber slap plate is tilted under normal circumstances, so that when the impact rod strikes downward, the rubber sleeve can first contact with the outer surface of the soaking bin body to offset a part of the force, and then drive the rubber slap plate to rotate in a circle with the connection point between itself and the impact rod, so that the rubber slap plate can finally strike the outer surface of the soaking bin body flatly. The above operation can prevent the force of the impact rod from causing too much damage to the soaking bin body when it strikes downward quickly and violently, thereby improving the service life of the soaking bin body and avoiding the problem that the traditional oscillating device uses a single rubber head for the soaking bin body, has a poor buffering effect, is easily deformed during use, and affects the rotation of internal blades.

[0019] The immersion device for treating lithium battery waste residue uses multiple flexible shafts for transmission in a power control component, which can avoid the energy consumption and cost increase caused by using redundant power sources to drive the movement of the mechanism. In addition, since the flexible shaft can have a certain buffering effect during transmission, the stability of the transmission can be increased to a certain extent, so that the inertial force generated when the mechanism starts and ends operation can be buffered to a certain extent, avoiding the problem of certain damage to the equipment caused by the inertia of opening and closing of the equipment in the traditional way, and improving the stability of the equipment operation.

[0020] The soaking device for treating lithium battery waste residue has corresponding worm gears in the oscillation homogenization component and the power control component. When the worm gears are engaged, they have certain deceleration and self-locking properties. The deceleration can amplify the initial torque of the second servo motor by several times while reducing the speed by several times, so that the power finally transmitted to the end of the mechanism can have sufficient torque to produce an effect, thereby further ensuring the efficiency and stability of the transmission.

[0029] Furthermore, the outer surface of the slider fixing frame 24 on one side is fixedly connected to the second fixing frame 34, and the second worm 35 is rotatably connected inside the second fixing frame 34. The end of the gear shaft 27 extending from the slider fixing frame 24 is fixedly sleeved with a second worm wheel 36, and the second worm wheel 36 is meshingly connected to the second worm wheel 35. The threads of the second worm wheels 35 in the two oscillation homogenization components are arranged in opposite directions.

[0030] Furthermore, the lifting plate 13 in the power control component is located above the soaking bin body 1, and the sprocket screw lifting assembly 18 is arranged on the lifting plate 13. The sprocket screw lifting assembly 18 is composed of a sprocket group and a screw. The sprocket screw lifting assembly 18 is used to drive the lifting plate 13 to move up and down, and the lifting plate 13 is fixedly connected to the motor fixing frame 16.

[0031] Furthermore, the first servo motor 17 is fixedly mounted on the motor fixing frame 16, and the output shaft of the first servo motor 17 is fixedly inserted into the central sprocket immersion bin body 1 of the sprocket screw lifting assembly 18, and the screw seat on the sprocket screw lifting assembly 18 is fixedly connected to the outer surface of the immersion bin body 1. The sprocket screw lifting assembly 18 is a prior art and will not be described in detail here.

[0032] Furthermore, the upper transmission cylinder 23 is rotatably connected to the lifting plate 13, the lower end of the upper transmission cylinder 23 is fixedly connected to the clutch fixing frame 14, the electric control clutch coupling 15 is fixedly installed in the clutch fixing frame 14, and the lower end of the upper transmission cylinder 23 is fixedly connected to the upper input shaft of the electric control clutch coupling 15; The lower transmission cylinder 11 is fixedly connected to the lower output shaft of the electric clutch coupling 15. The electric clutch coupling 15 is used to control the clutch of the transmission between the lower transmission cylinder 11 and the upper transmission cylinder 23. The electric clutch coupling 15 is a prior art and will not be described in detail here.

[0033] Furthermore, a gear sleeve 38 is fixedly sleeved on the outer surface of the upper transmission cylinder 23 , a second servo motor 37 is fixedly connected to the outer surface of the lifting plate 13 , and a gear meshing with the gear sleeve 38 is fixedly sleeved on the output shaft of the second servo motor 37 .

[0034] Furthermore, a first fixing frame 19 is fixedly connected to the surface of the screw seat on one side of the sprocket screw lifting assembly 18, a first worm 20 is rotatably connected to the soaking bin body 1 on the first fixing frame 19, a first worm wheel 21 is rotatably connected between the two vertical plates of the first fixing frame 19, the core shaft of the first worm wheel 21 rotates through the two vertical plates of the first fixing frame 19, and two flexible shafts 22 are fixedly connected to the two ends of the core shaft of the first worm wheel 21 respectively; The other ends of the two flexible shafts 22 are fixedly connected to the second worm gears 35 in the two oscillating homogenizing components respectively, and the same flexible shaft 22 is movably installed between the first worm gear 20 and the output shaft of the first servo motor 17 .

[0035] Furthermore, when in use, lithium battery waste and soaking solution are added into the soaking bin body 1, and then the first servo motor 17 is started. The output shaft of the first servo motor 17 drives the sprocket screw lifting assembly 18 to operate, so that the sprocket screw lifting assembly 18 can drive the lifting plate 13 to rise and fall synchronously until the soaking mixing assembly can enter the soaking bin body 1. At this time, the upper cover 12 will cover the soaking bin body 1, and then the second servo motor 37 is started. The second servo motor 37 can drive the tooth groove 28 to rotate through the engagement of the gear and the gear sleeve 38 thereon, and by controlling the connection of the electronically controlled clutch coupling 15, the tooth groove 28 can drive the lower transmission cylinder 11 and the upper inclined toothed disc 5 at its lower end to rotate together, and when the upper inclined toothed disc 5 rotates, the tooth belt on it is used. The movable bevel gear 8 rotates, and when the teeth on the rotating bevel gear 8 mesh with the fixed helical gear disc 3, the fixed helical gear disc 3 cannot rotate due to the sliding connection between the hexagonal fixed column 2 and the fixed hexagonal gear disc 3, which enables the fixed helical gear disc 3 to move in a circle around the fixed helical gear disc 3, and at the same time drives the hexagonal sleeve 4 to rotate on the hexagonal fixed column 2 by the inclined rotating shaft seat 6, so that the multiple rotating shafts 7 and the spiral blades 10 thereon can finally achieve a planetary motion of revolution and rotation at the same time. Through the planetary motion (revolution plus rotation) of the spiral blades 10, the lithium battery waste residue can be more evenly mixed in the immersion solution, ensuring that the waste residue is fully in contact with the solution, improving the reaction efficiency, and avoiding the problem of uneven mixing of the waste residue and the solution in the traditional method, resulting in some waste residue failing to fully react and reducing the overall treatment efficiency.

[0036] Furthermore, by setting the inclined rotating shaft seat 6 to be inclined, the axial directions of the rotating shaft 7 and the lower transmission cylinder 11 can also be inclined, so that when the immersion mixing assembly is running, the second servo motor 37 can make the multiple rotating shafts 7 rotate clockwise when revolving around the hexagonal fixed column 2 when rotating forward, and the spiral blades 10 thereon also rotate in the same direction. At this time, the rotation of the spiral blades 10 will apply a downward oblique force to the lithium battery waste residue and the immersion solution in the immersion bin body 1, so that the lithium battery waste residue and the immersion solution in the immersion bin body 1 can be driven by the force to form a three-dimensional centripetal vortex. This vortex flow will carry the lithium battery waste residue deposited at the bottom of the immersion bin 1 upward toward the center position, so that the lithium battery waste residue inside the immersion bin 1 can be further evenly mixed in the immersion solution. The inclined rotating shaft 7 and the spiral blade 10 can form a centripetal vortex flow when rotating, and carry the waste residue deposited at the bottom to the center position, further promoting mixing. The vortex flow helps to reduce the deposition of waste residue at the bottom and keep the waste residue in the solution evenly distributed, avoiding the traditional method in which the waste residue is easily deposited at the bottom, resulting in uneven mixing and insufficient reaction, and forming a mixing dead corner, affecting the overall treatment effect.

[0037] Furthermore, after the mixing is completed, the electronically controlled clutch coupling 15 is disconnected by controlling the upper transmission cylinder 23. At this time, the upper transmission cylinder 23 will not drive the lower transmission cylinder 11 to rotate. At this time, the flexible shaft 22 on the first worm 20 is connected to the output shaft of the second servo motor 37. At this time, the second servo motor 37 is started. The second servo motor 37 can drive the first worm 20 to rotate through the flexible shaft 22. When the first worm 20 rotates, the two flexible shafts 22 connected to the second worm 35 can be driven to rotate synchronously through the first worm wheel 21. The rotating flexible shaft 22 can drive the gear shaft 27 on the second worm wheel 36 to rotate through the second worm 35 thereon. When the gear shaft 27 rotates, it can drive the local gear 29 to rotate. When the local gear 29 rotates, the local teeth on it can drive the tooth groove 28 to move upward. At this time, the tension spring 30 is stretched and deformed until the local teeth on the local gear 29 are separated from the tooth groove 28. The impact rod 26 can be driven by the elastic contraction force of the tension spring 30 to impact downward rapidly and violently. The gravity of the counterweight bar 33 can make the rubber rapper 31 inclined under normal circumstances. When the impact rod 26 impacts downward, the rubber sleeve 32 can first contact the outer surface of the immersion bin 1, and then the rubber rapper 31 will hit the outer surface of the immersion bin 1 under the force of the impact rod 26 when it impacts downward, thereby generating a certain degree of shock force, so that the lithium battery waste slag in the immersion bin 1 can be evenly dispersed, and the mixed impurities therein can float on the surface, so that the separation efficiency of the materials in the lithium battery waste slag can be further improved. Through the impact of the impact rod 26 and the rubber rapper 31, a shock force is generated on the immersion bin 1, so that the waste slag is evenly dispersed, which helps the impurities to float to the surface and improves the separation efficiency. After the waste slag is evenly dispersed, the mixed impurities are more likely to float to the surface, which is convenient for subsequent separation processing, and the separation efficiency of the material is improved, avoiding the problem that in the traditional method, the waste slag and impurities are mixed together, the separation is not thorough, resulting in the loss of useful components and the reduction of the recovery rate.

[0038] Furthermore, by providing the counterweight bar 33, rubber sleeve 32 and rubber rapper 31, due to the gravity of the counterweight bar 33 itself, under normal circumstances, the rubber rapper 31 can be tilted by itself, so that when the impact rod 26 hits downward, the rubber sleeve 32 can first contact the outer surface of the soaking bin body 1 to offset a part of the force, and then drive the rubber rapper 31 to rotate in a circle with the connection point between itself and the impact rod 26, so that the rubber rapper 31 can finally hit the outer surface of the soaking bin body 1 flatly. The above operation can ensure that the force of the impact rod 26 when it hits downward quickly and violently will not cause too much damage to the soaking bin body 1, thereby improving the service life of the soaking bin body 1 and avoiding the problem that the traditional oscillation device uses a single rubber head of the soaking bin body 1, which has a poor buffering effect, is easy to cause the bin body to deform during use, and affects the rotation of the internal blades.

[0039] Furthermore, by using multiple flexible shafts 22 for transmission in the power control assembly, the energy consumption and cost increase caused by using excess power sources to drive the mechanism to move can be avoided. In addition, since the flexible shaft 22 can have a certain buffering effect during transmission, the stability of the transmission can be increased to a certain extent, so that the inertial force generated when the mechanism starts and ends operation can be buffered to a certain extent, avoiding the problem of certain damage to the equipment caused by the inertia of the opening and closing of the equipment in the traditional way, thereby improving the stability of the equipment operation.

[0040] Furthermore, by arranging corresponding worm gears in the oscillation homogenization component and the power control component, the worm gears have certain deceleration and self-locking properties when they are engaged. The deceleration property can amplify the initial torque of the second servo motor 37 by several times while reducing the speed by several times, so that the power finally transmitted to the end of the mechanism can have sufficient torque to produce an effect, thereby further ensuring the efficiency and stability of the transmission.

[0041] Working principle: When in use, lithium battery waste and soaking solution are added into the soaking bin body 1, and then the first servo motor 17 is started. The output shaft of the first servo motor 17 drives the sprocket screw lifting assembly 18 to operate, so that the sprocket screw lifting assembly 18 can drive the lifting plate 13 to rise and fall synchronously until the soaking mixing assembly can enter the soaking bin body 1. At this time, the upper cover 12 will cover the soaking bin body 1, and then the second servo motor 37 is started. The second servo motor 37 can drive the tooth groove 28 to rotate through the engagement of the gear and the gear sleeve 38 thereon, and by controlling the connection of the electronically controlled clutch coupling 15, the tooth groove 28 can drive the lower transmission cylinder 11 and the upper end thereof. The bevel gear discs 5 rotate together. When the upper bevel gear disc 5 rotates, the bevel gear 8 is driven to rotate through its upper teeth. When the teeth on the rotating bevel gear 8 are engaged with the fixed bevel gear disc 3, the fixed bevel gear disc 3 cannot rotate due to the sliding connection between the hexagonal fixed column 2 and the fixed bevel gear disc 3, which enables the fixed bevel gear disc 3 to move in a circle around the fixed bevel gear disc 3. At the same time, the hexagonal sleeve 4 is driven to rotate on the hexagonal fixed column 2 by the inclined rotating shaft seat 6, and finally the multiple rotating shafts 7 and the spiral blades 10 thereon can achieve a planetary motion of revolution and rotation at the same time. Through the planetary motion (revolution plus rotation) of the spiral blades 10, the lithium battery waste residue can be more evenly mixed in the immersion solution, ensuring that the waste residue is fully in contact with the solution, thereby improving the reaction efficiency.

[0042] Furthermore, by setting the inclined rotating shaft seat 6 to be inclined, the axial direction of the rotating shaft 7 and the lower transmission cylinder 11 can also be inclined, so that when the immersion mixing assembly is running, the second servo motor 37 can make the multiple rotating shafts 7 rotate clockwise when revolving around the hexagonal fixed column 2 when rotating forward, and the spiral blades 10 thereon also rotate in the same direction. At this time, the rotation of the spiral blades 10 will apply a downward force to the lithium battery waste residue and the immersion solution in the immersion bin body 1, so that the lithium battery waste residue and the immersion solution in the immersion bin body 1 can be driven by its force to form a three-dimensional centripetal vortex. This vortex flow will bring the lithium battery waste residue deposited at the bottom of the immersion bin body 1 to the center position and tilt upward, so that the lithium battery waste residue inside the immersion bin body 1 can be further evenly mixed in the immersion solution. When the inclined rotating shaft 7 and the spiral blades 10 rotate, they can form a centripetal vortex flow to bring the waste residue deposited at the bottom to the center position, further promoting mixing.

[0043] Furthermore, after the mixing is completed, the electronically controlled clutch coupling 15 is disconnected by controlling the upper transmission cylinder 23. At this time, the upper transmission cylinder 23 will not drive the lower transmission cylinder 11 to rotate. At this time, the flexible shaft 22 on the first worm 20 is connected to the output shaft of the second servo motor 37. At this time, the second servo motor 37 is started. The second servo motor 37 can drive the first worm 20 to rotate through the flexible shaft 22. When the first worm 20 rotates, the two flexible shafts 22 connected to the second worm 35 can be driven to rotate synchronously through the first worm wheel 21. The rotating flexible shaft 22 can drive the gear shaft 27 on the second worm wheel 36 to rotate through the second worm 35 thereon. When the gear shaft 27 rotates, it can drive the local gear 29 to rotate. When the local gear 29 rotates, the local teeth on it can drive the tooth groove 28 to move upward. At this time, the tension spring 30 is stretched and deformed until the local teeth on the local gear 29 are separated from the tooth groove 28, and the impact rod 26 can Driven by the elastic contraction force of the tension spring 30, it strikes downward rapidly and violently. At the same time, due to the self-gravity of the counterweight bar 33, the rubber rapper 31 can be inclined under normal circumstances. When the impact rod 26 strikes downward, the rubber sleeve 32 can first contact the outer surface of the immersion bin body 1, and then the rubber rapper 31 will hit the outer surface of the immersion bin body 1 under the force of the impact rod 26 when it strikes downward, thereby generating a certain degree of shock force, so that the lithium battery waste slag in the immersion bin body 1 can be evenly dispersed, and the mixed impurities therein can float on the surface, thereby further improving the separation efficiency of the materials in the lithium battery waste slag. Through the impact of the impact rod 26 and the rubber rapper 31, a shock force is generated on the immersion bin body 1, so that the waste slag is evenly dispersed, which helps the impurities to float to the surface, thereby improving the separation efficiency. After the waste slag is evenly dispersed, the mixed impurities are more likely to float to the surface, which is convenient for subsequent separation and processing.

[0044] Furthermore, by providing the counterweight bar 33, rubber sleeve 32 and rubber rapper 31, due to the gravity of the counterweight bar 33 itself, under normal circumstances, the rubber rapper 31 can be tilted by itself, so that when the impact rod 26 hits downward, the rubber sleeve 32 can first contact the outer surface of the soaking bin body 1 to offset a part of the force, and then drive the rubber rapper 31 to rotate in a circle with the connection point between itself and the impact rod 26, so that the rubber rapper 31 can finally hit the outer surface of the soaking bin body 1 flatly. The above operation can ensure that the force of the impact rod 26 when it hits downward quickly and violently will not cause too much damage to the soaking bin body 1.

[0045] Furthermore, by using multiple flexible shafts 22 for transmission in the power control assembly, the energy consumption and cost increase caused by using excess power sources to drive the mechanism to move can be avoided. In addition, since the flexible shaft 22 can have a certain buffering effect during transmission, the stability of the transmission can be increased to a certain extent, so that the inertial force generated when the mechanism starts and ends operation can be buffered to a certain extent.

[0046] Furthermore, by arranging corresponding worm gears in the oscillation homogenization component and the power control component, the worm gears have certain deceleration and self-locking properties when they are engaged. The deceleration property can amplify the initial torque of the second servo motor 37 by several times while reducing the speed by several times, so that the power finally transmitted to the end of the mechanism can have sufficient torque to produce an effect.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
