[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-6 As shown: One embodiment of the present invention is: A crushing and sorting device for recycling lithium batteries, comprising a shell 1, an outer cylinder 2 and an inner cylinder 3 arranged coaxially, the top of the outer cylinder 2 is connected to a feed hopper 201, the outer cylinder 2 is installed on the top of the shell 1 and is connected to the shell 1, a crushing assembly 4 is arranged in the inner cylinder 3, a screen 5 is installed at the bottom of the outer cylinder 2, openings 6 are opened at the top and bottom of the inner cylinder 3, and the size of the opening 6 is 90 degrees, the outer walls of the two opposite ends of the inner cylinder 3 are symmetrically rotated and connected with turntables 7, and the two turntables 7 are respectively rotatably embedded in the opposite ends of the outer cylinder 2, four partitions 8 are installed at equal angles between the two turntables 7, and the opposite ends of the partition 8 are respectively abutted against the inner wall of the outer cylinder 2 and the outer wall of the inner cylinder 3, and the opposite side walls of the inner cavity of the shell 1 are installed with reversible magnetic suction components 9, the shell A driving member 10 is installed on one side of the body 1, and an incomplete gear 11 is installed on the output shaft of the driving member 10. The first rotating gear 12 and the second rotating gear 13 are meshed and connected on opposite sides of the incomplete gear 11, and the incomplete gear 11 is meshed and connected with the first rotating gear 12 and the second rotating gear 13 in sequence. A gear ring 14 meshed and connected with the first rotating gear 12 is fixedly connected to the outer side of a turntable 7, and the second rotating gear 13 is connected to a reciprocating lifting member 15. One end of the magnetic attraction component 9 passes through the shell 1 and is installed with a third rotating gear 16 that matches the reciprocating lifting member 15. The incomplete gear 11 rotates one circle to first drive the gear ring 14 to rotate 90 degrees and then drive the second rotating gear 13 to rotate 180 degrees.

[0019] In this embodiment, in order to realize that the incomplete gear 11 rotates one circle to drive the gear ring 14 to rotate 90 degrees, the first rotating gear 12 and the gear ring 14 can be connected through a gear set to achieve a balanced transmission ratio.

[0020] In this embodiment, in order to enable the partition to better pick up the residue on the screen, the two opposite side surfaces of the end of the partition 8 abutting against the outer cylinder 2 are provided with arc-shaped mouths 81 away from each other, and the arc-shaped mouth 81 is close to the inner wall of the outer cylinder 2.

[0021] In this embodiment, the magnetic attraction component 9 includes a mounting frame 91 obliquely mounted on the inner wall of the shell 1, and the inner wall of the mounting frame 91 is rotatably connected to a magnetic attraction plate 92. One end of the rotating shaft of the magnetic attraction plate 92 passes through the side wall of the shell 1 and is installed with a third rotating gear 16. An obliquely arranged discharge plate 93 is installed at the bottom of the mounting frame 91, and the inclination angle of the discharge plate 93 is opposite to that of the mounting frame 91. A discharge port that cooperates with the discharge plate 93 is opened on the side wall of the shell 1. When the reciprocating lifting member is engaged with the third rotating gear, it can drive the magnetic attraction plate to flip, and then the power is cut off, so that the metal residue on the magnetic attraction plate can fall on the discharge plate and be discharged from the discharge plate to the discharge port for collection.

[0022] In this embodiment, in order to reduce the area occupied by the magnetic attraction plate when it is flipped and reduce the volume of the equipment, the magnetic attraction plate 92 is composed of a number of independently rotatable electromagnets 921 arranged side by side, one end of the rotating shaft of each electromagnet 921 passes through the side wall of the shell 1 and is equipped with a sprocket 922, and each sprocket 922 is connected by a chain 923 for transmission, and a third rotating gear 16 is installed at the end of the rotating shaft of an electromagnet 921, wherein when the third rotating gear rotates, it can drive the group of sprockets and electromagnets to rotate, and then synchronously drive the remaining sprockets and electromagnets to rotate through the chain, and finally realize the synchronous flipping of the electromagnets, and the large magnetic attraction plate is arranged to be composed of multiple groups of small electromagnets arranged side by side, so that when flipping, each electromagnet can flip independently, thereby reducing the excessive space occupied by the magnetic attraction plate when flipping.

[0023] In this embodiment, in order to realize that the electromagnet can be automatically powered off after all the magnetic suction plates are flipped over, a push switch 94 connected to the electromagnet 921 is installed on the side wall of the shell 1, and the reciprocating lifting member 15 presses the push switch 94 to power off the electromagnet 921 after reaching the lowest position.

[0024] In this embodiment, the reciprocating lifting member 15 includes a cam 151 installed on the surface of the second rotating gear 13 and a cover body 152 covered on the side of the housing 1. A lifting rod 153 is slidably connected to the surface of the cover body 152, and the top of the lifting rod 153 is a circle that cooperates with the cam 151. Racks 154 are symmetrically arranged on the two opposite sides of the lifting rod 153. A limiting block 155 is installed on the surface of the cover body 152. A mounting groove 156 is opened through the surface of the lifting rod 153. A limiting rod 157 is installed between the top and the bottom of the mounting groove 156, and the limiting rod 157 passes through the limiting block 155 and is slidably connected to the limiting block 155. The limiting rod 157 is A spring 158 is sleeved on the outer wall of 57, and the spring 158 is located between the limit block 155 and the top of the installation groove 156, wherein the rotation of the second rotating gear can synchronously drive the cam to rotate, so that when the protruding section of the cam gradually contacts the lifting rod, the lifting rod is pushed down and slides along the limit block through the limit rod, and after the protruding end of the cam rotates to the bottom, the lifting rod is pushed to the lowest position. At this time, the rack drives the third rotating gear to complete the rotation, and when the cam continues to rotate, the lifting rod gradually returns to its original position under the action of the spring restoring force, driving the third rotating gear to rotate in the opposite direction, so that the magnetic attraction plate is reset, thereby realizing the automatic flipping and resetting of the magnetic attraction plate.

[0025] In this embodiment, the crushing assembly 4 includes two crushing rollers 41 , one end of the rotating shafts of the two crushing rollers 41 passes through the side wall of the shell 1 and are respectively equipped with fourth rotating gears 42 that are meshed with each other, and the rotating shaft of one crushing roller 41 is connected to the driving member 10 .

[0026] In this embodiment, in order to reduce the overall cost of the equipment and facilitate the control of the equipment, the driving member 10 includes a driving motor 101, and the output shaft of the driving motor 101 is connected to two sets of pulley assemblies 102 through two one-way bearings in opposite directions. The two sets of pulley assemblies 102 are respectively connected to the rotating shaft of the crushing roller 41 and the rotating shaft of the incomplete gear 11. When the driving motor rotates forward, one set of pulley assemblies can drive the crushing roller to rotate to achieve crushing of the lithium battery (the incomplete gear remains stationary during this process), and when the driving motor rotates reversely, the incomplete gear is driven to rotate through another set of pulley assemblies (the crushing roller remains stationary during this process).

[0027] In this embodiment, in order to improve the screening and filtering effect and avoid the accumulation of materials on the screen, four reciprocating screw rods 17 are connected between the two turntables 7 at equal angles, and the four reciprocating screw rods 17 are respectively located at the center of the area surrounded by the four partitions 8. The outer wall of the reciprocating screw rod 17 is threadedly connected with a slider 18, and the slider 18 is connected to an arc-shaped brush 20 that abuts against the inner wall of the outer cylinder 2 through a connecting rod 19, and the two ends of the arc-shaped brush 20 abut against two adjacent partitions 8. One end of the reciprocating screw rod 17 passes through the side wall of the shell 1 and is installed with a fifth rotating gear 21. The end of the inner cylinder 3 is rotatably connected to a fourth rotating gear 21. The moving gear 42 is meshedly connected to the transition gear 22, and the transition gear 22 is meshedly connected to a group of fifth rotating gears 21 located below, wherein the fourth rotating gear of the crushing roller drives the fifth rotating gear located below to rotate through the transition gear, thereby driving the group of reciprocating screws to rotate, thereby driving the slider and the arc-shaped brush to slide back and forth, cleaning the surface of the screen to avoid clogging the screen holes of the screen, and when the turntable rotates, the fifth rotating gear located below is separated from the transition gear, and the fifth rotating gear of the next group is gradually meshed with the transition gear, so that the screen can be cleaned at each stage.

[0028] In this embodiment, an inclined second material guide plate is disposed at the lower part of the housing 1, and a discharge port is correspondingly opened on the surface.

[0029] A crushing and sorting method for recycling lithium batteries, using the above-mentioned crushing and sorting device for crushing and sorting, the specific process is as follows: The pyrolyzed lithium battery is fed into the inner cylinder 3 through the feed hopper 201 and the opening 6 above the inner cylinder 3, and the drive motor 101 is started in the forward direction. The drive motor 101 drives the two crushing rollers 41 to rotate in opposite directions through a pulley assembly 102 to crush the lithium battery, and the crushed lithium battery falls onto the screen 5 from the opening 6 below the inner cylinder 3, while some materials that meet the particle size pass through the screen 5 and fall onto the magnetic plate 92 and roll along the magnetic plate 92. In the crushing process, a fourth rotating gear 42 drives the fifth rotating gear 21 and the reciprocating screw 17 located below to rotate through the transition gear 22, and the reciprocating screw 17 drives the slider 18 and the arc brush 20 to clean the surface of the screen 5 to prevent the material from accumulating on the screen 5 and causing blockage. When the material falls on the magnetic plate 92, some non-metallic materials (graphite) roll downward along the inclined angle of the magnetic plate 92, and are caught by the magnetic plate 92 on the other side and continue to roll, while some metal materials are adsorbed on the magnetic plate 92 during the rolling process, and the material is sorted in this reciprocating manner.

[0030] After a period of crushing, the driving motor 101 is started in the reverse direction (at this time, the crushing roller 41 stops rotating), and the driving motor 101 drives the incomplete gear 11 to rotate through the pulley assembly 102. The incomplete gear 11 first meshes with the first rotating gear 12, thereby driving the gear ring 14 and the turntable 7 to rotate, so that the four partitions 8 rotate, so that the materials located above the screen 5 are scooped up through the partitions 8 and gradually rotated to the next position (that is, gradually rotated 90 degrees). In this process, when the partitions 8 scoop up the materials, some of the small particles accumulated in the materials can fall down along the screen 5 again, and after the incomplete gear 11 is separated from the first rotating gear 12, the gear ring 14 and the turntable 7 stop rotating (the partitions 8 rotate 90 degrees); Then the incomplete gear 11 meshes with the second rotating gear 13 to drive the cam 151 to gradually rotate from a horizontal state, thereby pushing the lifting rod 153 to gradually slide downward, thereby driving the third rotating gear 16 to rotate through the racks 154 on both sides, thereby driving each electromagnet 921 to turn synchronously through the cooperation of the chain 923 and the sprocket 922, and when the lifting rod 153 slides to the bottom, the electromagnet 921 turns 90 degrees, and the lifting rod 153 contacts the push switch 94 to cut off the power to the electromagnet 921, so that the metal material falls on the guide plate 93 and is discharged from the shell 1. Then the cam 151 gradually disengages from the lifting rod 153, and the lifting rod 153 gradually returns to its original position under the action of the restoring force of the spring 158, so that the push switch 94 is disengaged, the electromagnet 921 is energized again to generate attraction, and then drives the third rotating gear 16 to rotate in the opposite direction, so that the electromagnet 921 returns to its initial angle position, until the cam 151 rotates to the horizontal position on the other side (that is, the cam 151 rotates 180 degrees), the lifting rod 153 returns to the highest position, and in order to ensure the fixation of the electromagnet 921, the rack 154 is still engaged with the third rotating gear 16.

[0031] Then the incomplete gear 11 meshes with the first rotating gear 12, driving the gear ring 14 and the turntable 7 to rotate 90 degrees again, so that the material falls into the inner cylinder 3 again, and then the incomplete gear 11 meshes with the second rotating gear 13, driving the cam 151 to rotate 180 degrees (that is, the incomplete gear 11 rotates two circles in the whole process), and finally the driving motor 101 rotates forward to drive the crushing roller 41 to crush the material. In this way, the lithium battery is crushed and sorted reciprocatingly. The whole process can cyclically crush the lithium battery to improve the crushing effect, and automatic magnetic suction is used for sorting during the sorting process, which can effectively distinguish between metal materials and non-metallic materials.

[0032] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
