Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship power lithium battery, and particularly relates to a ship power lithium battery crushing device. BACKGROUND

[0002] As a core energy storage component of new energy ships, the ship power lithium battery has the characteristics of high energy density and long endurance, and is composed of a positive electrode, a negative electrode, an electrolyte and a thickened metal shell. With the large-scale application of the ship power lithium battery, harmless disposal and valuable metal recovery of waste ship power lithium batteries have become a key problem in the industry. The crushing process is a core process of lithium battery recycling, which directly determines the purity, recovery efficiency and operation safety of subsequent component separation. At present, the waste lithium battery recycling field generally adopts an integrated process of 'primary crushing + screening separation + secondary crushing', and the treatment of ship power lithium batteries also follows this mode.

[0003] However, when the existing crushing equipment with an intermediate screen is applied to the treatment of ship power lithium batteries, the primary crushing generally adopts a general shearing or hammering structure, which is not matched with the special structure of the thickened metal shell and the internal pole piece of the lithium battery, resulting in a large difference in the particle size of the crushed materials. Large materials are easily stuck in the fixed screen, and small pole pieces are easily wound around the crushing components. Even if a simple material cleaning structure is provided, it is also difficult to completely solve the problems of blockage and winding, and frequent manual cleaning is required, which greatly reduces the operation efficiency. In addition, the screening accuracy of the general screen cannot meet the requirements, and part of the unqualified materials are easily mixed into the qualified material flow, which directly affects the purity of the subsequent component recovery. In addition, the two-stage crushing chambers are independently driven, and the running parameters are not matched with the state of the screened materials. Only the fixed speed and the opening degree of the feed inlet can be maintained, and the actual size and hardness of the large materials cannot be adjusted. This easily causes the overload of the main shaft of the secondary crushing chamber and the heating of the motor, and long-term uneven load also accelerates the wear of the equipment, which seriously restricts the continuity and stability of the lithium battery recycling process.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] Example: Please see Figures 1 to 16A crushing device for marine power lithium batteries includes a crushing box 1, a discharge shell 4, and a support 3. Inside the crushing box 1, below the feed inlet, is a main shaft 30 connected via bearings. A primary crushing mechanism is located on the outer side of the main shaft 30. A partition plate 34 connects to the inner wall of the crushing box 1, dividing the discharge outlet at the bottom of the crushing box 1 into a primary discharge channel and a secondary discharge channel. A sliding opening 35 is provided on the right side of the crushing box 1, with a blocking plate 19 slidably connected inside the sliding opening 35. A screen 29 is rotatably connected to the top edge of the partition plate 34. An opening and closing mechanism is provided on the outer side of the crushing box 1, used to discharge large pieces of screened material from the primary discharge channel into the secondary discharge channel. A secondary crushing mechanism is located inside the crushing box 1 at the secondary discharge channel on one side of the partition plate 34, used for secondary crushing of the large pieces of material screened by the screen 29. An adjustment mechanism is provided on the outer side of the crushing box 1, used to adjust the crushing spacing of the secondary crushing mechanism. A control console 6 is connected to the front of the crushing box 1.

[0020] Working Principle: The crushing box 1 and the discharge shell 4 are stably supported by the bracket 3. The marine power lithium battery to be crushed is fed into the feed port of the crushing box 1. The primary crushing mechanism can perform preliminary shell breaking and coarse crushing of the lithium battery. The partition plate 34 is fixed to the inner wall of the crushing box 1 by welding, dividing the bottom discharge port into independent primary discharge channel and secondary discharge channel. The screen 29 is rotatably connected to the top edge of the partition plate 34 through a rotating shaft, which can classify and screen the coarsely crushed material. The sliding port 35 provides a sliding track for the blocking plate 19. The blocking plate 19 and the sliding port 35 cooperate to achieve a sliding connection, which can control the opening and closing of the primary discharge channel. The opening and closing mechanism can drive the screen 29 to flip and the blocking plate 19 to slide, and guide the screened large pieces of material into the secondary discharge channel. The secondary crushing mechanism performs secondary fine crushing of the large pieces of material. The adjustment mechanism can precisely adjust the crushing distance of the secondary crushing mechanism. The control console 6 is electrically connected to each power component through wires to realize the overall automated control of the equipment, ensuring the orderly connection of the crushing, screening and secondary crushing processes, and solving the problem of process disconnection in existing equipment.

[0021] Please see Figures 1 to 16The primary crushing mechanism includes multiple parallel extrusion shells 31, multiple symmetrical hammers 51, multiple baffles 7, and multiple circumferentially distributed teeth 46. Each hammer 51 is adapted to the interior of the extrusion shell 31. A first base plate 56 is connected to one end of each hammer 51 near the main shaft 30. A rubber interlayer 58 is connected to one side of each first base plate 56 near the main shaft 30. A second base plate 57 is connected to one side of each rubber interlayer 58 near the main shaft 30. Multiple mounting grooves 47 adapted to the second base plates 57 are formed on the outer surface of the main shaft 30. The side of each second base plate 57 near the main shaft 30 is connected to the inner wall of the mounting groove 47. Multiple sets of first cutting blades 48 are connected to the two opposing inner sidewalls of the compression shell 31 from top to bottom. Arc-shaped limiting plates 49 are connected to the middle of the bottom surface of each compression shell 31. Multiple anti-slip plates 50 are connected to the end surface of each arc-shaped limiting plate 49. The surface of the crushing box 1 is connected to the first motor 16 by bolts. The first motor 16 can be a variable frequency asynchronous motor with variable frequency speed regulation function. The speed of the main shaft 30 can be adjusted by the control console 6 according to the thickness of the lithium battery shell to meet the load fluctuation requirements of the first-stage crushing mechanism. The drive end of the first motor 16 is connected to one end of the main shaft 30. The first motor 16 is electrically connected to the control console 6 through wires.

[0022] Working principle: The first motor 16 is fixed to the surface of the crushing box 1 by bolts. Its drive end is connected to one end of the main shaft 30 via a coupling. After starting, it drives the main shaft 30 to rotate at a constant speed. The hammer head 51 is connected to the main shaft 30 through a composite structure of the first base plate 56 + rubber interlayer 58 + second base plate 57. The second base plate 57 is fixed to the mounting groove 47 of the main shaft 30 by bolts. The rubber interlayer 58 provides elastic cushioning, enabling the hammer head 51 to have elastic extension and contraction capabilities. Multiple symmetrical hammer heads 51 are adapted to the interior of the parallel extrusion shell 31. When in motion, it forms a shearing and extrusion space with the inner wall of the extrusion shell 31. The staggered first cutting blades 48 on the inner side wall of the extrusion shell 31 enhance the crushing effect. The circumferentially distributed teeth 46 increase the biting force on the thickened shell. The baffle 7 separates adjacent hammers 51 to prevent materials from entangled in the main shaft 30 and further facilitates the crushing of lithium batteries. The arc-shaped limiting plate 49 is fixed to the bottom surface of the extrusion shell 31 by bolts. The anti-slip plate 50 at its end can prevent materials from sliding too fast, ensuring sufficient crushing, solving the problem of poor adaptability of general crushing structures, and achieving efficient coarse crushing.

[0023] Please see Figures 1 to 16Each extrusion shell 31 has an internal opening that is wider at the top and narrower at the bottom. The inner side of each extrusion shell 31 opposite to the main shaft 30 is an arc-shaped surface. The angle between the first cutting blade 48 in the lower middle part of each extrusion shell 31 and the arc-shaped surface gradually decreases from 5° to 15°. Each baffle 7 is located between two hammers 51. Multiple prismatic grooves 53 are provided on both sides of each hammer 51. Prismatic sliders 52 are slidably connected inside each prismatic groove 53. Widening adjustment plates 55 are provided on both sides of each hammer 51. The side of each widening adjustment plate 55 near the hammer 51 is connected to the side of the corresponding prismatic slider 52. Multiple positioning bolts 54 are threadedly connected to the inner wall of each widening adjustment plate 55 and the inner wall of the hammer 51.

[0024] Working principle: The internal opening of the extrusion shell 31 is designed to be wider at the top and narrower at the bottom, which facilitates material feeding and allows the material to gradually gather. The inner side of the extrusion shell 31 opposite to the main shaft 30 is an arc-shaped surface, which conforms to the rotation trajectory of the hammer head 51 and reduces material jamming. The included angle of the first cutting blade 48 in the middle and lower part gradually decreases from 5° to 15° with the included angle of the arc-shaped surface, so that the crushing force gradually increases from the feeding end to the discharge end, improving the crushing uniformity. The baffle 7 is located between the two hammer heads 51, which can prevent material from accumulating in the gap between the hammer heads 51. The prismatic groove 53 on the side of the hammer head 51 cooperates with the prismatic slider 52 on the widening adjustment plate 55 to achieve a sliding connection. The widening adjustment plate 55 can be removed by the positioning bolt 54 to facilitate the adjustment of the thickness of the hammer head 51, adapting to the crushing requirements of lithium batteries of different sizes.

A connecting frame 65 is connected to the outside of the combined gear 66. A second motor 18 is bolted to the surface of the connecting frame 65. The second motor 18 can be a reduction stepper motor with precise angle control function. It can achieve precise matching between the sliding distance of the toothed plate 43 and the flipping angle of the screen 29 through the control console 6, ensuring that the blocking plate 19 synchronously switches the first-level discharge channel and avoids jamming when the rope 45 pulls the screen 29.

[0028] Working principle: The third motor 20 is fixedly installed through the third bearing seat 21. The drive end passes through the third bearing seat 21 and is connected to the adjustment platform 70. The bottom end of the adjustment platform 70 is rotatably connected to the groove on the surface of the support platform 71 through a rotating shaft to ensure stable rotation.

[0030] Working principle: The first crushing shaft 40, the second crushing shaft 42, the third crushing shaft 41, and the fourth crushing shaft 72 are rotatably connected to the crushing box 1 via bearings and are installed in a V-shape inside the secondary discharge channel. The first crushing shaft 40 and the second crushing shaft 42 are horizontally arranged in the upper layer, and the third crushing shaft 41 and the fourth crushing shaft 72 are horizontally arranged in the lower layer, forming a two-stage crushing space. The fourth motor 28 is fixed to the surface of the fourth bearing seat 17 by bolts, and the drive end is connected to the fourth crushing shaft 72. The fourth motor 72 is driven by the sixth gear ring 25 in conjunction with the third gear belt 13. The rotation of the gear ring 26 drives the second crushing shaft 42 to rotate, which in turn drives the main shaft 30 to rotate via the first motor 16. The main shaft 30 drives the first gear ring 23 to rotate via the third gear ring 27 and the first gear belt 10, which in turn drives the first crushing shaft 40 to rotate. The rotation of the first crushing shaft 40 then drives the fifth gear ring 24 to rotate via the second gear ring 22 and the second gear belt 12, thus achieving synchronous operation of each crushing shaft. The V-shaped layout allows the material to fall gradually under the action of gravity and be crushed multiple times, solving the problem of insufficient crushing in existing two-stage crushing mechanisms.

[0031] Please see Figures 1 to 16The adjustment mechanism includes an adjustment frame 15, a hydraulic cylinder 14, a miniature pressure sensor 73, and a distance sensor 39. These core components are required externally to the hydraulic cylinder 14 to ensure operation.

These components work together to achieve stable pressure, precise adjustment, and safety protection, adapting to the dynamic adjustment requirements of the secondary crushing distance. The outer surface of the crushing box 1 has adjustment ports 32 on one side of each of the two fourth bearing seats 17. The outer surface of each fourth bearing seat 17 is slidably connected to the interior of the adjustment port 32. Each adjustment port 32... Multiple threaded positioning grooves 33 are provided on both sides of the lower part. Each fourth bearing seat 17 is connected to the threaded positioning groove 33 by bolts.

The outer surface of the miniature pressure sensor 73 is connected to the upper surface of the screen 29. The hydraulic cylinder 14 and the distance sensor 39 are both electrically connected to the control console 6 through wires.

[0032] Working principle: The fourth bearing seat 17 and the adjustment port 32 cooperate to achieve a sliding connection. The two ends of the adjustment frame 15 pass through the crushing box 1 and are fixedly connected to the two fourth bearing seats 17. The hydraulic cylinder 14 is fixed to the surface of the crushing box 1 by bolts. Its telescopic end is connected to the adjustment frame 15, which can push the adjustment frame 15 to drive the fourth crushing shaft 72 to slide along the adjustment port 32. The distance sensor 39 is fixed to the surface of the adjustment frame 15 to detect the distance between the fourth crushing shaft 72 and the third crushing shaft 41 in real time and feed the data back to the control console 6 to form a closed-loop control. The threaded positioning grooves 33 on the upper and lower sides of the adjustment port 32 can be used to fix the fourth bearing seat 17 with bolts to enhance the stability after adjustment. The weight pressure of large materials is detected by the micro pressure sensor 73. The crushing distance can be dynamically adjusted according to the hardness and size of the material to avoid overload failure and solve the problem that the existing equipment cannot adapt to different materials.

[0033] Please see Figures 1 to 16 The top inclined surface of the partition plate 34 contacts the bottom inclined surface of the blocking plate 19. The screen 29 is located at the first-level discharge channel on one side of the partition plate 34. The bottom surface of the screen 29 contacts the inner wall protrusion of the crushing box 1. The inner bottom wall of the sliding port 35 and the top of the partition plate 34 are integrated inclined surfaces. The bottom surface of the crushing box 1 is connected to the upper surface of the discharge shell 4. The top of the support 3 is connected to the bottom surface of the discharge shell 4.

[0034] Working principle: The top inclined surface of the partition plate 34 is in close contact with the bottom inclined surface of the blocking plate 19 to improve the sealing performance. The bottom surface of the screen 29 is in contact with the inner wall protrusion of the crushing box 1 to form a support and positioning, ensuring structural stability during screening. The inner bottom wall of the sliding port 35 and the top of the partition plate 34 are integrated inclined surfaces to facilitate material discharge from the screen 29. The bottom surface of the crushing box 1 is fixed to the discharge shell 4 with bolts. The top of the bracket 3 is welded to the bottom surface of the discharge shell 4 to achieve stable support for the entire equipment. The movable plate 59 on the upper surface of the blocking plate 19 and the movable groove 60 cooperate to achieve a sliding connection, enhancing the smoothness of the sliding of the blocking plate 19. The first protective shell 2 and the second protective shell 5 are fixed to the surface of the crushing box 1 with bolts to protect the toothed belt and the adjustment mechanism, respectively, to prevent dust from entering and parts from being exposed and causing safety hazards. The cooperation between the movable plate 59 and the movable groove 60 can also play a dustproof role, preventing material debris from entering the sliding gap and affecting operation.

[0035] In summary, when the entire equipment is in use: the marine power lithium battery to be crushed is pre-treated and fed into the feed inlet of the crushing box 1. The control console 6 starts the first motor 16, which drives the main shaft 30 and the outer primary crushing mechanism. The hammer 51 rotates with the main shaft 30 through the composite structure of the first base plate 56 + rubber interlayer 58 + second base plate 57. It cooperates with the inner wall of the extrusion shell 31 and the staggered first cutting blades 48 to shear and extrude the lithium battery to achieve initial shell breaking and coarse crushing. The circumferentially distributed teeth 46 increase the biting force on the thickened shell. The anti-slip plate 50 at the end of the arc-shaped limiting plate 49 slows down the material's downward speed to ensure sufficient crushing. At the same time, the thickness of the hammer 51 can be adjusted by removing the positioning bolts 54 to adapt to the material's needs. Different sized lithium batteries are used to control the particle size of coarsely crushed materials. The coarsely crushed materials fall onto screen 29 for grading and screening. Qualified materials fall into the discharge shell 4 through the primary discharge channel, while large pieces remain on screen 29. During this process, the anti-blocking component works simultaneously. The third motor 20 drives the adjusting table 70 to rotate, which drives the cleaning brush 67 to swing back and forth along the fan-shaped track 38, continuously cleaning the blockages and tangled electrode sheets at the bottom of screen 29 to ensure continuous screening. The control console 6 starts the second motor 18, which drives the toothed plate 43 to slide through the meshing transmission of the first combination gear 66 and the second combination gear 62, causing the blocking plate 19 to open the primary discharge channel. At the same time, the winding shaft 8 rotates and pulls the screen 29 along the arc track through the rope 45. The 36th channel flips, guiding large pieces of material into the secondary discharge channel. The large pieces of material entering the secondary discharge channel fall between the V-shaped first crushing shaft 40, second crushing shaft 42, third crushing shaft 41, and fourth crushing shaft 72. The fourth motor 28 is bolted to the surface of the fourth bearing seat 17, and its drive end is connected to the fourth crushing shaft 72. The sixth gear ring 25, in conjunction with the third gear belt 13, drives the fourth gear ring 26 to rotate, which in turn drives the second crushing shaft 42 to rotate. The first motor 16 then drives the main shaft 30 to rotate. The main shaft 30, through the third gear ring 27 and the first gear belt 10, drives the first gear ring 23 to rotate, which in turn drives the first crushing shaft 40 to rotate. The rotation of the first crushing shaft 40... The second toothed ring 22, in conjunction with the second toothed belt 12, drives the fifth toothed ring 24 to rotate, thereby achieving synchronous operation of all crushing shafts and synchronous rotation of the four-stage crushing shafts for secondary fine crushing of the material. The control console 6 can push the adjusting frame 15 through the hydraulic cylinder 14, thereby driving the fourth crushing shaft 72 to slide along the adjusting port 32. The distance sensor 39 provides real-time feedback of the spacing data to form a closed-loop control. The miniature pressure sensor 73 detects the weight and pressure of large materials and dynamically adjusts the crushing spacing to match the material hardness and size, avoiding overload failure. The finely crushed material finally falls into the discharge shell 4 to complete the crushing process. The control console 6 achieves automated control, solving problems such as poor adaptability of existing equipment, screen 29 blockage, and insufficient crushing.
