Description

Technical Field

[0001] The invention belongs to the technical field of waste lithium battery recycling, and in particular relates to a battery core crushing device for recycling waste lithium batteries. Background Art

[0002] Most of the existing waste lithium battery recycling equipment crushes the waste lithium batteries and then recycles them by screening. Before crushing, they need to be discharged. To save costs, they need to be discharged using salt water. This discharge method often takes a lot of time, and the treatment of salt water is also troublesome. A time-saving method is to use a single-axis shredding roller to reduce the oxygen content in the working chamber to less than 2% during the crushing process. The crushing operation is live, but the electrodes in the waste batteries will be squeezed together during the crushing process, resulting in short-term contact heat release and temperature rise. Fire or explosion is very likely to occur if the oxygen content is not controlled stably. Summary of the invention

[0003] The present application proposes a battery core crushing device for recycling waste lithium batteries, which has the advantages of good crushing effect and not easy to explode or catch fire, and is used to solve the problem that battery cores are easy to gather together during transportation and crushing.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a battery core crushing equipment for recycling waste lithium batteries, comprising a single-axis roller, one end of which is fixedly connected to a transmission shaft, the single-axis roller is composed of recessed areas arranged at intervals to form a continuously tortuous axis, the recessed areas are provided with a gear ring and a gear ring, the peripheral circular array of the gear ring has three planetary gears, the planetary gears are meshed with the gear ring and the gear ring, the gear ring cooperates with the non-recessed area of ​​the single-axis roller to form a concentric cylindrical surface, a moving knife is fixedly installed on the outer wall of the non-recessed area of ​​the single-axis roller and the outer peripheral wall of the gear ring, the left and right sides of the single-axis roller are provided with a fixed knife for cooperating with the moving knife to form a shearing effect, and the fixed knife is fixedly installed on the base plate.

[0005] Furthermore, a movable sleeve in the middle of the single-axis roller is provided with a movable tooth block, which is rectangular and hollow, and racks are provided on the upper and lower inner walls of the hollow part. The transmission shaft is located in the hollow part of the movable tooth block and a driving gear is provided. The driving gear is an incomplete gear, and the incomplete gear is meshed with the rack for transmission. The end of the movable tooth block is fixedly connected to a movable block, and the top of the movable block is fixedly connected to an extrusion plate, which is slidably connected to the top of the base plate. The extrusion plates are arranged on the left and right sides of the single-axis roller, and the extrusion plates are used to feed materials to the matching position of the fixed knife and the movable knife.

[0006] Furthermore, a support frame is fixedly installed on the top of the two extrusion plates, and a feed bin is fixedly installed on the top of the support frame. The feed bin is located above the single-axis roller and moves left and right.

[0007] Furthermore, long grooves are provided on both sides of the bottom of the feed bin, and the height of the long grooves is used to limit the discharge rate.

[0008] Furthermore, a sliding wheel is provided between the extrusion plate and the base plate, a protruding block is provided above the base plate, and the sliding wheel is in surface contact with the protruding block.

[0009] Furthermore, a sealing baffle is provided above the moving tooth block of the uniaxial roller, and the sealing baffle is fixedly mounted on the fixed knife. The sealing baffle is used to fill the depression of the uniaxial roller at the moving tooth block to prevent material from entering.

[0010] Furthermore, the transmission ratio between the gear ring and the gear in the uniaxial roller is 1:2. Beneficial Effects

[0011] The present application provides a battery core crushing device for recycling waste lithium batteries. The single-axis roller is in a zigzag state, and a toothed ring is provided at the concave part. The outer part of the toothed ring is meshed with a planetary gear, and the outer part of the planetary gear is meshed with a toothed ring. Under the action of the planetary gear, the toothed ring and the single-axis roller rotate in opposite directions, so that the single-axis roller and the toothed ring are tangent to each other, and the crushing effect is better. In addition, the two-way crushing can effectively disperse the batteries to be crushed, thereby avoiding the short-time contact heat release of the pole pieces and reducing the large-area short-circuit heat release phenomenon.

[0012] The present application provides a battery core crushing equipment for recycling waste lithium batteries. The driving gear of the single-axis roller is specifically a gear structure with half teeth and half no teeth. Racks are respectively provided on the upper and lower parts of the moving tooth block. The teeth of the driving gear are meshed with the moving tooth block, thereby driving the reciprocating movement of the moving tooth block. The moving tooth block is connected to the moving block to drive the synchronous movement of the extrusion plate, and the material to be crushed is intermittently pushed to the fixed knife edge to prevent the material from being crushed too concentratedly and causing safety hazards.

[0013] The present application provides a battery core crushing device for recycling waste lithium batteries. The reciprocating movement of the extrusion plate drives the movement of the feed bin above the extrusion plate. During the movement of the extrusion plate, the internal battery cores will be screened and fall into the space between the extrusion plate and the single-axis roller from the long grooves on the left and right sides of the feed bin, thereby achieving a more even distribution of the battery cores and avoiding safety accidents such as explosion or fire caused by concentrated accumulation.

DETAILED DESCRIPTION

[0016] 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.

[0017] like Figure 3 , Figure 4 and Figure 6 As shown, a battery core crushing equipment for recycling waste lithium batteries includes a single-axis roller 5, one end of which is fixedly connected to a transmission shaft 4. The single-axis roller 5 is specifically a continuously tortuous shaft, and a gear ring is provided at the recessed part thereof. The transmission shaft 4 drives the single-axis roller 5 to rotate, and the internal gear ring also rotates synchronously at the same time. There are three planetary gears 12 in a circumferential array around the internal gear ring, and a gear ring 13 is meshed on the periphery of the planetary gear 12. The gear ring 13 and the outer wall of the gear ring 13 and the single-axis roller 5 are both provided with a movable knife 7 in an annular array, and the movable knife 7 is fixedly installed by bolts. Through the planetary gear 12, the internal gear ring of the single-axis roller 5 forms a relative reversal with the gear ring 13, and the transmission ratio of the single-axis roller 5 to the gear ring 13 is 2:1. When the transmission shaft 4 drives the single-axis roller 5 to rotate, the gear ring 13 at the recessed interval of the single-axis roller 5 rotates in the opposite direction relative to the single-axis roller 5. The differential reverse rotation of the uniaxial roller 5 and the gear ring 13 forms the main and auxiliary crushing functions. At the same time, the differential reverse rotation is beneficial to disperse the materials to be crushed accumulated on the uniaxial roller 5 and the gear ring 13 to prevent excessive concentration.

[0018] like Figure 2As shown, the driving gear 11 at the center position of the uniaxial roller 5 is in the shape of an incomplete gear, specifically a half-side gear with half teeth and half no teeth. The outside of the driving gear 11 is sleeved with a moving tooth block 14, and racks are provided at the upper and lower ends of the moving tooth block 14. When the transmission shaft 4 drives the uniaxial roller 5 to rotate, the driving gear 11 is integrated with the uniaxial roller 5, and the driving gear 11 will also rotate. At the same time, the teeth of the driving gear 11 are meshed with the teeth of the moving tooth block 14, and the moving tooth block 14 will also reciprocate left and right with the rotation of the driving gear 11. The moving tooth block 14 is fixedly connected to the moving block 9. The extrusion plate 3 is connected above the moving block 9, and the extrusion plate 3 will move synchronously with the reciprocating movement of the moving tooth block 14. The reciprocating movement of the extrusion plate 3 will make the space between the extrusion plate 3 and the uniaxial roller 5 gradually smaller and then larger, so that the battery core in the space can be pushed into the uniaxial roller 5 for crushing.

[0019] like Figure 4 and Figure 5 As shown, a base plate 8 is provided below the extrusion plate 3, a raised block is provided above the base plate 8, a sliding wheel 15 is embedded inside the bottom of the extrusion plate 3, and the sliding wheel 15 is in contact with the raised block surface above the base plate 8, which is used to fix the extrusion plate 3 for lateral movement, and a fixed knife 6 is fixed at one end of the base plate 8 close to the uniaxial roller 5, and the fixed knife 6 cooperates with the uniaxial roller 5 and the movable knife 7 on the surface of the gear ring 13, and a sealing partition 10 fixed above the fixed knife 6 by bolts above the center position of the fixed knife 6 and the uniaxial roller 5 is used for sealing.

[0020] like Figure 1 and Figure 4 As shown, a rectangular support frame 2 is provided above the extrusion plate 3 by bolt connection, and a feed bin 1 is welded above the center of the support frame 2. The feed bin 1 will move synchronously with the reciprocating movement of the extrusion plate 3. During the synchronous movement, the feed bin 1 will flatten the internal battery cores and finally fall into the space between the extrusion plate 3 and the uniaxial roller 5, achieving the effect of uniform distribution of the battery cores. Long grooves are provided on both sides of the bottom of the feed bin 1, and the height of the long groove is only enough for one cylindrical battery to pass through.
