Description

Technical Field

[0001] This invention relates to the field of battery recycling, and more particularly to an environmentally friendly crushing and sorting device for battery resource recycling and processing. Background Technology

[0002] With the widespread adoption of new energy vehicles and portable electronic products, the amount of waste batteries generated is surging year by year. Resource recycling of waste lithium batteries can not only alleviate the pressure of metal resource shortages but also reduce environmental pollution. Currently, the mainstream recycling process includes steps such as discharge, crushing, sorting, pyrolysis, and hydrometallurgy. Among these, crushing and sorting are key pretreatment steps for subsequent extraction of valuable metals. Existing crushing and sorting devices typically include crushers and vibrating screens. The crushed material is then graded by particle size using a vibrating screen to separate components such as black powder, copper foil, and aluminum foil of different particle sizes. However, in actual production, this process still has some shortcomings:

[0003] On the one hand, after being crushed, waste batteries are prone to forming clumps of varying sizes due to the residual electrolyte and binders. These clumps are difficult to break up effectively on a vibrating screen, causing some incompletely dissociated valuable metals (such as cobalt and lithium) to enter the tailings directly with the large particles of slag, resulting in resource loss and a decrease in the recovery rate.

[0004] On the other hand, existing vibrating screens are mostly open linear or circular vibration structures. Material slides forward too quickly on the screen surface under gravity, and fine particles are discharged from the outlet before they can pass through the screen, resulting in low screening efficiency. Especially when the throughput increases, the material layer thickens, making it even harder for fine powder to contact the screen surface, further exacerbating the problem of incomplete screening. Therefore, this solution proposes an environmentally friendly crushing and sorting device for battery resource recycling. Summary of the Invention

[0005] The present invention proposes an environmentally friendly crushing and sorting device for battery resource recycling and processing, which solves the problems of low screening efficiency and incomplete screening caused by powder agglomeration and excessive material slippage in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly crushing and sorting device for battery resource recycling includes a crushing section and a screening section. The screening section is located below the crushing section and is used to screen the crushed battery fragments. The screening section includes:

[0008] The receiving mechanism includes a screening frame, a screening plate movably installed inside the screening frame, and a conveyor belt installed inside the screening frame for outputting the debris screened off the screening plate to the outside of the screening frame, wherein the screening plate is inclined.

[0009] The transmission mechanism includes a movable plate movably mounted on the outer walls of the long sides of the screening frame and a power component mounted on the outer wall of the screening frame for driving the movable plate to reciprocate along the length of the screening plate, wherein the movable plate is connected to the screening plate.

[0010] Multiple material blocking mechanisms are provided, and the multiple material blocking mechanisms are evenly arranged along the top surface of the screening plate to regulate the sliding speed of the material on the screening plate. The material blocking mechanism includes a mounting shaft rotatably connected inside it along the width direction of the screening frame and multiple elastic material blocking plates evenly installed on the outer periphery of the mounting shaft. The moving plate is equipped with a driving component for driving the mounting shaft to rotate in one direction.

[0011] The dispersing mechanism includes an interception component and a striking component. The striking component is connected to the moving plate via a linkage to drive the striking component to disperse the agglomerated material during the movement of the moving plate.

[0012] As a further improvement to the above solution, a first discharge port is provided on the top of the short side of one side of the screening frame, and connecting grooves are provided on both long sides of the screening frame along the length of the screening plate. The screening plate includes a screen and a first connecting plate and a second connecting plate respectively fixed at both ends of the screen. A baffle is fixed on the top surface of the first connecting plate, and the second connecting plate is located inside the first discharge port. Multiple connecting posts are fixed on both long sides of the screening plate. The other end of the connecting post passes through the connecting groove and is fixed to the movable plate. The connecting post is slidably connected to the connecting groove.

[0013] Through the above technical solution, the connecting column passes through the connecting groove to rigidly connect the screening plate and the moving plate, so that the reciprocating motion of the moving plate can be directly transmitted to the screening plate, forming a stable vibration screening effect; at the same time, the baffle can effectively prevent large pieces of material that are not completely crushed from rolling directly from the end of the first connecting plate.

[0014] As a further improvement to the above solution, the crushing section includes a crushing bucket and two crushing rollers installed inside the crushing bucket. Both ends of the two crushing rollers are rotatably connected to the inner wall of the crushing bucket through fixed shafts. One end of each of the two fixed shafts at the same end of the two crushing rollers extends to the outside of the crushing bucket and is fixed with a linkage gear. The two linkage gears mesh with each other. A second drive motor is installed on the outer wall of the other side of the crushing bucket. The output end of the second drive motor is connected to the fixed shaft on one of the crushing rollers through a coupling. The bottom of the crushing bucket is provided with a discharge port, which is located directly above the first connecting plate.

[0015] Through the above technical solution, the two crushing rollers achieve synchronous reverse rotation through the linkage gear, which crushes the battery material by squeezing, and the discharge port is directly opposite the first connecting plate, ensuring that the crushed material falls accurately into the starting end of the screening plate.

[0016] As a further improvement to the above solution, the power assembly includes a driven wheel rotatably connected to the outer wall of one side of the screening frame, a deflector column rotatably connected to one side of the driven wheel at a position off-center from the center along the axial direction of the driven wheel, a fixed frame movably sleeved on the outer periphery of the deflector column, and a drive motor installed on the outer wall of the screening frame. A drive wheel is fixedly sleeved on the output shaft of the drive motor, and the drive wheel and the driven wheel are connected by belt drive. The top of the fixed frame is fixedly connected to the moving plate on that side of the screening frame, and the inner circle length of the fixed frame is greater than the diameter of the driven wheel.

[0017] Through the above technical solution, the drive motor drives the active wheel to rotate, and the driven wheel is driven to rotate through the belt drive. The actuating column, which is off-center, performs reciprocating push-pull motion within the fixed frame, thereby converting the rotational motion into the linear reciprocating motion of the moving plate.

[0018] As a further improvement to the above solution, the elastic baffle plate includes a movable plate and a fixed sleeve plate movably sleeved on one long side of the movable plate. One long side of the fixed sleeve plate is fixedly connected to the outer periphery of the mounting shaft, and the side of the movable plate located inside the fixed sleeve plate is fixedly connected to the inner wall of the fixed sleeve plate by a connecting spring.

[0019] With the above technical solution, when the elastic baffle rotates to contact the material layer, if it encounters large hard particles or a thick layer of powder, the movable plate can compress the connecting spring and retract into the fixed sleeve plate, thereby adaptively avoiding the material. This ensures the material blocking effect and prevents the mechanism from jamming or being damaged.

[0020] As a further improvement to the above solution, both ends of the mounting shaft extend to the outside of the screening frame and are fixedly fitted with ratchet wheels. The driving component includes a toothed plate fixed on its top surface along the length direction of the moving plate and ratchet teeth installed on the top surface of the toothed plate. The ratchet teeth cooperate with the ratchet wheel to drive the ratchet wheel to rotate as the toothed plate moves with the moving plate toward the side closer to the first discharge port.

[0021] With the above technical solution, each time the moving plate reciprocates, the ratchet teeth on the toothed plate push the ratchet to rotate at a fixed angle only in one stroke direction, realizing the unidirectional intermittent rotation of the mounting shaft. During the reverse stroke, the ratchet teeth slip and do not transmit power, thereby realizing the unidirectional flipping of the elastic baffle plate and achieving the purpose of controlling the material release rhythm.

[0022] As a further improvement to the above solution, the interception component is located directly above the first connecting plate. It includes a mounting plate fixed inside the frame along the width direction and multiple limiting rods fixed on the long side of the mounting plate away from the screen. The limiting rods are inclined and their lower ends contact the top surface of the first connecting plate. There is a gap between two adjacent limiting rods.

[0023] Through the above technical solution, the inclined limiting rods form a grid-like interception structure. When the material falls from the discharge port, larger lumps or incompletely broken pieces are blocked by the limiting rods in the first connecting plate area and cannot directly enter the screen, making it convenient for the subsequent striking components to strike and break them.

[0024] As a further improvement to the above solution, the striking assembly includes a rotating shaft rotatably connected to its inner side along the width direction of the screening frame, multiple striking rods fixed to its outer periphery along the radial direction of the rotating shaft, and a transmission component installed on the outer wall of the screening frame for driving the rotating shaft to rotate periodically. The multiple striking rods and multiple limiting rods are staggered.

[0025] With the above technical solution, the feeding rod and the limiting rod are staggered, so that when the feeding rod swings, it can pass through the gap between the limiting rods and apply a downward striking force to the blocked lumpy material, breaking it into small particles and allowing it to pass smoothly through the gap and fall into the screen.

[0026] As a further improvement to the above solution, both ends of the rotating shaft extend to the outside of the screening frame, and a swing arm is fixed on the outer periphery of the portion of the rotating shaft located on the outside of the screening frame, which is arranged in the radial direction. The transmission component includes a fixed ring movably passing through the swing arm, a return spring movably sleeved on the outer periphery of the fixed ring, a fixed plate fixed on the top surface of the moving plate, and a push shaft rotatably connected to the outer wall of one side of the fixed plate. The fixed ring and the rotating shaft are coaxially arranged, and both ends of the fixed ring are fixed to the outer wall of the screening frame through fixed blocks. One end of the return spring is fixed to one of the fixed blocks, and the other end of the return spring is fixed to the outer wall of the swing arm. The outer periphery of the push shaft abuts against the outer periphery of the swing arm to push the swing arm to rotate when the moving plate moves.

[0027] With the above technical solution, when the moving plate moves towards the first discharge port, the fixed plate drives the push shaft to move forward synchronously. The push shaft presses against the swing arm, causing it to rotate around the rotating shaft. The reset spring is compressed, and the rotating shaft drives the material-beating rod to strike downwards. When the moving plate moves back in the opposite direction, the push shaft disengages from the swing arm, the reset spring releases its elastic potential energy, drives the swing arm to rotate back to reset, and the material-beating rod is lifted upwards, completing a complete striking cycle. Moreover, the striking frequency matches the vibration frequency, eliminating the need for additional control mechanisms.

[0028] As a further improvement to the above solution, a second discharge port is provided on the side of the screening frame away from the first discharge port. The conveyor belt is inclined and the lower end of the conveyor belt extends through the second discharge port to the outside of the screening frame. A discharge trough is provided on the outer wall of one long side of the screening frame along its length direction. A guide plate is fixed on the inner wall of the bottom of the screening frame, and the top surface of the guide plate is an inclined surface that is inclined downward toward the discharge trough.

[0029] With the above technical solution, the debris falling from the conveyor belt can be discharged from the discharge chute through the guide plate, avoiding its accumulation in the screening box.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. By setting a baffle mechanism inside the screening frame, and cooperating with the reciprocating vibration of the screening plate, the mounting shaft is driven to rotate unidirectionally according to the vibration frequency, thereby effectively limiting the speed at which the material box slides down from the first discharge port on the screening plate, increasing the screening time on the screening plate, and thus improving the screening effect.

[0032] 2. The elastic baffle plate adopts a structure with a sliding fit between the movable plate and the fixed sleeve plate and an internal connecting spring. This allows it to adaptively compress and avoid encountering accumulated materials or hard particles during the turning process. This ensures reliable material blocking and speed control while avoiding equipment damage or power overload caused by rigid collisions, thus improving the stability and service life of the device.

[0033] 3. The limiting rod in the dispersing mechanism intercepts agglomerated materials at fixed points, and the reciprocating motion of the moving plate, through the mechanical linkage of the swing arm and the push shaft, drives the material-beating rod to periodically strike the intercepted material. The striking rhythm is coordinated with the screening vibration, and the crushed powder immediately falls into the screen for screening, effectively preventing valuable metals from being lost with large pieces of slag and improving the resource recovery rate.

[0045] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0046] Example 1:

[0047] Please combine Figure 1 - Figure 9 This embodiment describes an environmentally friendly crushing and sorting device for battery resource recycling and processing, mainly used for pre-screening of crushed waste lithium battery materials. The device includes a crushing section and a screening section.

[0048] The crushing section is located at the top of the device and includes a crushing bucket 1 and two parallel crushing rollers 2 installed inside the crushing bucket 1. Both ends of the two crushing rollers 2 are rotatably connected to the inner wall of the crushing bucket 1 via fixed shafts, and the fixed shafts at the same end of both crushing rollers 2 extend to the outside of the crushing bucket 1 and are fixedly fitted with linkage gears, which mesh with each other. A second drive motor is installed on the outer wall of the other side of the crushing bucket 1, and the output shaft of the second drive motor is connected to the fixed shaft of one of the crushing rollers 2 via a coupling. A discharge port is provided at the bottom of the crushing bucket 1 to discharge the crushed material downwards. In this embodiment, the surface of the crushing rollers 2 may be machined with staggered crushing teeth to enhance the tearing ability of the battery casing.

[0049] The screening section is located directly below the crushing bucket 1 and includes a receiving mechanism, a transmission mechanism, a blocking mechanism 5, and a dispersing mechanism.

[0050] The receiving mechanism includes a screening frame 3, a screening plate 4, and a conveyor belt 9. The screening frame 3 is a rectangular box structure with an open top. A first discharge port 6 is opened at the top of one short side, and a second discharge port 11 is opened at the bottom of the short side away from the first discharge port 6. Connecting grooves 28 extending along the length direction are opened in the middle of the outer walls of the two long sides of the screening frame 3. The screening plate 4 is inclinedly arranged inside the screening frame 3, with its higher end close to the discharge port of the crushing hopper 1 and its lower end extending into the first discharge port 6. Specifically, the screening plate 4 includes a screen 401 located in the middle and a first connecting plate 402 and a second connecting plate 403 respectively fixed at both ends of the screen 401. The first connecting plate 402 is located directly below the material discharge port, and a baffle 24 is vertically fixed to its top surface. The second connecting plate 403 passes through the first discharge port 6 and extends to the outside of the screening frame 3. The first connecting plate 402 is used to catch the material falling from the crushing hopper 1 and facilitates the dispersing mechanism to break up clumps. The second connecting plate 403 is used to facilitate the discharge of material on the screen 401 from the first discharge port 6. The second connecting plate 403 is located directly above one end of the conveyor belt 9 inside the screening frame 3, which also effectively prevents material from falling onto the outside of the end of the conveyor belt 9. Multiple connecting posts 30 are evenly fixed on both long sides of the screening plate 4. The connecting posts 30 pass through the corresponding connecting grooves 28 and are fixedly connected to the moving plate 8 located outside the screening frame 3. The connecting posts 30 can slide freely in the connecting grooves 28, so that the screening plate 4 can vibrate during the reciprocating movement of the moving plate 8.

[0051] The conveyor belt 9 is installed at the inner bottom of the screening frame 3, directly below the screen 401. The conveyor belt 9 is inclined, with its lower end extending from the second discharge port 11 to the outside of the screening frame 3 to receive and output the fine powder that passes through the screen 401. A discharge chute 7 is provided at the bottom of the outer wall of one long side of the screening frame 3, running along the length direction. A guide plate 29 is fixed to the inner bottom surface of the screening frame 3. The top surface of the guide plate 29 is an inclined surface that slopes downward toward the discharge chute 7, which facilitates the guidance of any small amount of material that the conveyor belt 9 fails to carry away in time to the discharge chute 7 for discharge.

[0052] The transmission mechanism includes a movable plate 8 and a power assembly. Two movable plates 8 are provided, slidably attached to the outer walls of the two long sides of the screening frame 3, and the outer ends of all connecting posts 30 are welded and fixed to the movable plate 8 on the same side. The power assembly is installed on one outer wall of the screening frame 3 and includes a driven wheel 16, an actuating post 17, a fixed frame 18, and a drive motor. The driven wheel 16 is rotatably connected to the outer wall of the screening frame 3 via a bearing seat, and the actuating post 17 is vertically fixed to one side of the driven wheel 16 at a position offset from the center. The fixed frame 18 is a rectangular frame that movably fits around the actuating post 17, and the top of the fixed frame 18 is fixedly connected to the bottom surface of the movable plate 8 on the same side. The drive motor is fixed to the outer wall of the screening frame 3, and a driving wheel 27 is fixedly sleeved on its output shaft. The driving wheel 27 and the driven wheel 16 are connected by a transmission belt. Once the drive motor starts, the driving wheel 27 drives the driven wheel 16 to rotate via a belt. The actuating column 17 then rotates around the central axis of the driven wheel 16, reciprocating within the fixed frame 18. This drives the fixed frame 18 and the moving plate 8 to reciprocate linearly along the length of the screening plate 4. In this embodiment, the inner length of the fixed frame 18 is greater than the diameter of the driven wheel 16 to ensure that the actuating column 17 does not interfere with the inner wall of the fixed frame 18 during rotation.

[0053] The implementation principle of this embodiment is as follows: Waste battery material is fed into the top of the crushing hopper 1, crushed by two crushing rollers 2, and falls from the bottom discharge port onto the first connecting plate 402 of the screening plate 4. At this time, the drive motor drives the moving plate 8 to reciprocate, and the entire screening plate 4 vibrates at high frequency. Under the action of vibration, the material gradually slides along the inclined screen 401 towards the first discharge port 6. Fine particles pass through the screen 401 and fall into the conveyor belt 9 below, and are discharged through the second discharge port 11 by the conveyor belt 9; large particles continue to slide to the first discharge port 6 and are discharged. The blocking mechanism 5 intermittently hinders the material during the sliding process to prolong the screening time; at the same time, the dispersing mechanism breaks up the lumps of material encountered during the sliding process to prevent valuable metals from being lost with large pieces of slag.

[0054] Example 2:

[0055] Please combine Figure 2 , Figure 4 , Figure 6 and Figure 8 This embodiment is further improved on the basis of embodiment 1 in that:

[0056] Multiple material blocking mechanisms 5 are provided, evenly arranged above the screen 401 along its length. Each material blocking mechanism 5 includes a mounting shaft 501 and multiple elastic baffles. The two ends of the mounting shaft 501 pass through the long side walls of the screening frame 3 and extend to the outside, and the mounting shaft 501 is rotatably connected to the walls of the screening frame 3 via bearings. Multiple elastic baffles are evenly fixed to the outer periphery of the mounting shaft 501 along its axial direction. Each elastic baffle consists of a movable plate 502 and a fixed sleeve 503. One long side of the fixed sleeve 503 is welded and fixed to the outer periphery of the mounting shaft 501, and the other long side has an opening slot. One long side of the movable plate 502 is inserted into the opening slot of the fixed sleeve 503, and the portion inside the fixed sleeve 503 is fixedly connected to the inner wall of the fixed sleeve 503 via multiple connecting springs. The uninserted end of the movable plate 502 extends outward for direct contact with the material. When the movable plate 502 is subjected to external pressure, the compressible connecting spring retracts into the fixed sleeve plate 503, thereby changing the overall extension length of the elastic baffle plate.

[0057] Ratchets 10 are fixedly sleeved at both ends of the mounting shaft 501. Correspondingly, toothed plates 15 extending along their length are fixed on the top surfaces of both moving plates 8. Multiple ratchet teeth 14 are hinged to the top surfaces of the toothed plates 15 by pins, and the ratchet teeth 14 engage with the ratchet 10 on the same side. The mounting direction of the ratchet teeth 14 is configured as follows: when the moving plate 8 moves towards the first discharge port 6 (i.e., forward stroke), the toothed plate 15 moves accordingly, and the tips of the ratchet teeth 14 engage in the tooth grooves of the ratchet 10, pushing the ratchet 10 to rotate by a fixed tooth pitch angle, thereby driving the mounting shaft 501 to rotate by a certain angle; when the moving plate 8 moves away from the first discharge port 6 (i.e., reverse stroke), the ratchet teeth 14 slide over the back of the teeth of the ratchet 10, do not transmit driving force, and the ratchet 10 remains stationary.

[0058] The implementation principle of this embodiment is as follows: During each forward stroke of the reciprocating vibration of the screening plate 4, the moving plate 8 drives the ratchet 10 to rotate unidirectionally by a step angle through the ratchet teeth 14, causing the elastic baffle on the mounting shaft 501 to flip downstream by a fixed angle. The flipping of the elastic baffle allows the material to pass over the baffle position in small batches and continue to slide downstream, without forming a continuous and rapid flow of material. When the material accumulation is large or there are hard lumps, the moving plate 502 can adaptively retract to avoid jamming. By reasonably setting the number of elastic baffles and the number of teeth of the ratchet 10, the average sliding speed of the material can be precisely controlled to ensure that fine particles obtain sufficient screening time.

[0059] Example 3:

[0060] Please combine Figure 4 , Figure 5 , Figure 7This embodiment is further improved on the basis of Embodiments 1 and 2 in that:

[0061] The dispersing mechanism is located inside the screening box 3, near the first connecting plate 402, that is, directly below the material discharge port. This mechanism includes an interception component and a striking component.

[0062] The interception assembly includes a mounting plate 26 and multiple limiting rods 25. The mounting plate 26 is horizontally fixed between the inner walls of its two long sides along the width direction of the screening frame 3. The multiple limiting rods 25 are all vertically fixed on the long side of the mounting plate 26 facing the screen 401, and the limiting rods 25 are inclined downwards, with their free ends contacting or leaving a small gap with the top surface of the first connecting plate 402. There is a gap between two adjacent limiting rods 25, the width of which is larger than the target screening particle size, so that particles that have reached the particle size requirement after crushing can slide directly into the area of ​​the screen 401 through the gap, while lumps or flaky materials that exceed the size limit are intercepted on the upstream side of the limiting rods 25.

[0063] The striking assembly includes a rotating shaft 13, striking rods 12, and a transmission component. The rotating shaft 13 is arranged along the width direction of the screening frame 3, with its two ends passing through the long side walls of the screening frame 3 and rotatably connected to them via bearings. Multiple striking rods 12 are fixed radially to the portion of the rotating shaft 13 located inside the screening frame 3. The number of striking rods 12 is the same as the number of limiting rods 25, and the multiple striking rods 12 and the multiple limiting rods 25 are staggered in horizontal projection, meaning that each striking rod 12 can just pass through the gap between two adjacent limiting rods 25 when it swings.

[0064] Both ends of the rotating shaft 13 extending beyond the screening frame 3 are fixed with radially extending swing arms 21. A transmission component, comprising a fixed ring 19, a return spring 20, a fixed plate 23, and a push shaft 22, converts the reciprocating motion of the moving plate 8 into periodic rotation of the rotating shaft 13. The fixed ring 19 is sleeved on the outer circumference of the swing arms 21 and is coaxial with the rotating shaft 13. Both ends of the fixed ring 19 are fixedly connected to the outer wall of the screening frame 3 via fixed blocks, meaning the fixed ring 19 remains stationary relative to the screening frame 3. The return spring 20 is sleeved on the outer circumference of the fixed ring 19, with one end fixedly connected to one of the fixed blocks and the other end fixedly connected to the side wall of the swing arm 21. In its natural state, the return spring 20 keeps the swing arm 21 at its initial angle, causing the feeding rod 12 to lift upwards. The fixed plate 23 is vertically fixed to the top surface of the moving plate 8, and the push shaft 22 is rotatably connected to the outer wall of the fixed plate 23 facing the swing arm 21 via a bearing seat. The outer peripheral surface of the push shaft 22 abuts against the outer peripheral surface of the swing arm 21.

[0065] The implementation principle of this embodiment is as follows: When the moving plate 8 moves towards the first discharge port 6 (forward stroke), the fixed plate 23 and the push shaft 22 move forward synchronously. The outer circumferential surface of the push shaft 22 presses against the swing arm 21, forcing the swing arm 21 to swing upward around the axis of the rotating shaft 13, and the return spring 20 is compressed. The swing arm 21 drives the rotating shaft 13 to rotate forward, and the discharge rod 12 swings downward and passes through the gap between the limit rods 25, applying a downward striking force to the agglomerated material intercepted on the first connecting plate 402, breaking it up. When the moving plate 8 moves away from the first discharge port 6 (reverse stroke), the push shaft 22 retracts, releasing the compression on the swing arm 21. The return spring 20 releases its elastic potential energy, driving the swing arm 21 to swing back and reset. The rotating shaft 13 rotates in the reverse direction, and the discharge rod 12 lifts up, leaving the material area. This cycle repeats, with the discharge rod 12 striking periodically at the same beat as the vibration frequency, achieving continuous online breaking of the agglomerated material.

[0066] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
