Description

Technical Field

[0001] The present invention relates to the technical field of waste lithium battery recycling and treatment, and in particular to a waste lithium battery material recycling and treatment device. Background Art

[0002] Cylindrical lithium batteries are widely used in 3C products, power tools and new energy vehicles due to their high energy density, safety and consistency. Used cylindrical lithium batteries usually contain valuable metal materials such as lithium, cobalt, nickel and manganese. The correct disposal method should include recycling and professional treatment to reduce environmental pollution and recover valuable materials.

[0003] At present, there are two main methods for recycling waste cylindrical lithium batteries:

[0004] The first method is manual operation. First, the cap of the battery needs to be cut open manually using tools, and then the battery cell is removed by knocking, shearing or cutting, and then the positive electrode material, negative electrode material and separator are separated. In batch disassembly operations, the cap and shell of each battery need to be cut manually, which is not only time-consuming and labor-intensive, but also has low work efficiency. Manual operation may cause workers to be cut by knives or sharp shells after cutting, which is less safe. Due to the limited accuracy of manual operation, some valuable materials may be damaged or lost during the disassembly process, thus affecting the recycling efficiency.

[0005] The second method is mechanical crushing, which is to directly put the battery into the crusher for crushing, and then screen and separate the valuable materials. Although this method can increase the disassembly speed, it requires the transfer of the crushed batteries and additional screening processes, which will affect the overall work efficiency. In addition, after the battery is crushed, the valuable materials may adhere to materials such as the diaphragm, making it difficult to screen, which ultimately affects the recycling efficiency.

The overall shape of the baffle 29 is U-shaped and is located directly behind the mounting frame 9.

[0032] First, place the cylindrical lithium battery in the loading frame 28, and the cylindrical lithium battery will roll to the left along the inner bottom surface of the loading frame 28, and the conveyor belt 3 will block the cylindrical lithium battery on the left side of the loading frame 28, and then the conveyor belt 3 is driven by the electric roller 2 to rotate intermittently. When the discharge trough 301 on the conveyor belt 3 rotates to align with the cylindrical lithium battery on the left side of the loading frame 28, the cylindrical lithium battery on the left side will roll to the left into the discharge trough 301 of the conveyor belt 3 on the upper and lower sides, and then the conveyor belt 3 will drive the upper cylindrical lithium battery to rotate intermittently. The cylindrical lithium batteries are intermittently transported to the left, and the conveyor belt 3 can block the remaining cylindrical lithium batteries in the discharge trough 301. When the cylindrical lithium batteries move to just below the electric push rod Ⅰ5, the conveyor belt 3 stops rotating; at this time, the lifting frame Ⅱ24 can be driven to move upward by the electric push rod Ⅱ23, and the lifting frame Ⅱ24 can drive the blocking frame 25 to move upward, so that the two blocking frames 25 are respectively located at the front and rear sides of the cylindrical lithium batteries; at the same time, the lifting frame Ⅰ6 can be driven to move downward by the electric push rod Ⅰ5, and the lifting frame Ⅰ6 can drive the driving The motor 7, the circular blade 8, the swing rod 12 and the electric roller 14 move downward, and the electric roller 14 will first contact the surface of the cylindrical lithium battery. The electric rollers 14 on the left and right sides will be squeezed and swing away from the cylindrical lithium battery to drive the swing rod 12 to swing and expand, and the connecting spring 13 will stretch. Under the action of the connecting spring 13, the electric rollers 14 on the left and right sides can be closely attached to the surface of the cylindrical lithium battery. At the same time, the circular blade 8 can be driven to rotate by the driving motor 7. When the circular blade 8 contacts the cap of the cylindrical lithium battery, When the cylindrical lithium battery is cut, the cap edge of the cylindrical lithium battery can be cut, and then the cylindrical lithium battery is driven to rotate in the discharge trough 301 by the electric roller 14. The auxiliary roller 302 plays a role in reducing friction to assist the cylindrical lithium battery to rotate, so that the circular blade 8 can completely cut off the cap of the cylindrical lithium battery. The baffle frame 25 can prevent the cap of the cylindrical lithium battery from flying out during the cutting process, so that the cut cylindrical lithium battery cap can fall down along the inner wall of the baffle frame 25 into the collection frame I 26;Then the electric push rod II 23 drives the lifting frame II 24 to move downward and reset, and the lifting frame II 24 can drive the blocking frame 25 to move downward and reset, so that the blocking frame 25 will no longer block the front and rear sides of the cylindrical lithium battery, so as not to block the cylindrical lithium battery with the cap cut to continue to be transported to the left, and will not block the next cylindrical lithium battery from being transported to the bottom of the electric push rod I5. At the same time, the lifting frame I6 can be driven by the electric push rod I5 to move upward and reset, and the lifting frame I6 can drive the driving motor 7, the circular blade 8, the swing rod 12 and the electric roller 14 to move upward and reset, so that the electric roller 14 is separated from the cylindrical lithium battery with the cap cut, and the connecting spring 13 will be restored. The electric rollers 14 on the left and right sides are swung back to their original state, thereby driving the electric rollers 14 on the left and right sides to swing back to the direction close to the cylindrical lithium battery. Then the conveyor belt 3 continues to rotate, and the cylindrical lithium battery with the cap cut can be conveyed to the left between the mounting frame 9 and the retaining frame 29, and the next cylindrical lithium battery can be conveyed to the bottom of the electric push rod Ⅰ5; when the lifting frame Ⅰ6 drives the circular blade 8 to move downward to cut the cap of the next cylindrical lithium battery, the lifting frame Ⅰ6 can drive the fixed plate 17 and the active rack 18 to move downward, and the active rack 18 can drive the driven gear 21 to rotate, and the driven gear 21 can drive the rotating rod through the one-way clutch 19 rotates, the rotating rod 19 can drive the reciprocating screw rod 16 to rotate through the pulley assembly 20, and the reciprocating screw rod 16 can drive the sliding frame 10 to reciprocate back and forth once. When the sliding frame 10 moves backward, it can drive the arc blade 11 to move backward. When the arc blade 11 contacts the cylindrical lithium battery shell that has been capped, the arc blade 11 can cut the shell of the cylindrical lithium battery. The blocking frame 29 can block the rear side of the cylindrical lithium battery to prevent the cylindrical lithium battery from moving, and the left and right sides of the arc blade 11 are inclined surfaces, so that the material in the cylindrical lithium battery shell can be squeezed to the middle to prevent the material in the cylindrical lithium battery from being cut by the arc blade. When the sheet 11 is cut off, when the sliding frame 10 moves forward and resets, it can drive the arc blade 11 to move forward and reset to separate from the cylindrical lithium battery. When the lifting frame I6 drives the circular blade 8 to move upward and separate from the next cylindrical lithium battery, the lifting frame I6 can drive the fixed plate 17 and the active rack 18 to move upward and reset. The active rack 18 can drive the driven gear 21 to reverse. Under the action of the one-way clutch, the driven gear 21 will not drive the rotating rod 19 to rotate; then the conveyor belt 3 continues to rotate, and the cylindrical lithium battery with the shell cut off can be conveyed to the left, so that the cylindrical lithium battery with the shell cut off falls into the collection frame II27, which is convenient for subsequent unified processing. ;

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
