Description

Technical Field

[0001] This invention relates to the field of power battery recycling technology, and in particular to a high-efficiency sorting and recycling device for power batteries. Background Technology

[0002] With the popularization of new energy vehicles, after a certain number of years or kilometers of use, the performance of the power battery will degrade to a certain extent, and the power battery used in new energy vehicles needs to be replaced. The replaced power battery contains metal resources such as lithium, cobalt, and nickel, so it is necessary to recycle the used power battery.

[0003] In the process of recycling used power batteries, the existing used power battery sorting and recycling equipment has a relatively simple structure, which makes it inconvenient to sort used power batteries according to their size and to accurately disassemble them later. In addition, when used power batteries are separated from the battery pack, a small amount of impurities may be attached to the surface of the used power batteries. The existing used power battery sorting and recycling equipment cannot fully remove the impurities attached to the surface of the used power batteries, which may interfere with the subsequent recycling of used power batteries. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the present invention provides a high-efficiency sorting and recycling device that can efficiently sort waste power batteries according to their size and efficiently remove impurities attached to the surface of waste power batteries.

[0005] The technical solution of this invention is: a high-efficiency sorting and recycling device for power batteries, comprising:

[0006] Main support;

[0007] The drive motor is fixedly connected to the upper part of the main support;

[0008] The feed frame is fixed to the upper part of the main support;

[0009] The rotating shaft is rotatably connected to the upper part of the main support. One end of the rotating shaft is fixedly connected to the output shaft of the drive motor, and the rotating shaft passes through the feed frame.

[0010] The supporting circular frame is rotatably connected between the rotating shaft and the feed frame;

[0011] The screening ring is rotatably connected to the outside of the supporting circular frame, and multiple waste discharge grooves are opened on the screening ring.

[0012] The discharge assembly is located on the main support.

[0013] The sorting components are located on the screening ring;

[0014] The auxiliary adjustment component is located on the main support.

[0015] In one embodiment, the discharge assembly includes: an inclined frame, slidably connected to the middle of the main support, with several through slots on the inclined frame; a return spring connected between the inclined frame and the main support; a baffle fixed to the lower part of the inclined frame; a guide seat fixed to the lower part of the main support; a transmission frame slidably connected to the guide seat; a multi-slot discharge frame fixed to one side of the transmission frame, with three discharge slots on the multi-slot discharge frame; and an impurity frame fixed to the transmission frame.

[0016] In one embodiment, the sorting assembly includes: three small limiting frames fixed to the screening ring; three medium limiting frames fixed to the screening ring; three large limiting frames fixed to the screening ring; a small spur gear fixed to the rotating shaft; a support rod fixed to the upper part of the main support, the support rod being fixed to the support circular frame; a transmission spur gear rotatably connected to the support rod, the transmission spur gear meshing with the small spur gear; and a spur gear ring fixed to one side of the screening ring, the transmission spur gear meshing with the spur gear ring.

[0017] In one embodiment, the auxiliary adjustment component includes: a limiting ring fixed to the outside of the screening ring, the limiting ring having an inner arc surface, a middle arc surface and an outer arc surface; a guide frame fixed to the main support; a lifting frame slidably connected to the guide frame; a helical spring connected between the guide frame and the lifting frame; a transmission push frame fixed to the bottom of the lifting frame, the transmission push frame having a transmission groove; and a support rod fixed to one side of the transmission frame, the support rod being located in the transmission groove on the transmission push frame.

[0018] In one embodiment, a flipping assembly is also included, which is disposed on the rotating shaft. The flipping assembly is used to flip the used power battery. The flipping assembly includes: two rotating frames fixed to the rotating shaft; and a flipping ring fixed between the two rotating frames.

[0019] In one embodiment, a screening auxiliary component is also included, disposed on the rotating shaft. The screening auxiliary component is used to shake the inclined frame. The screening auxiliary component includes: a support plate fixed to the rotating shaft; a plurality of protrusions fixed to the support plate; and a push frame fixed to the side of the inclined frame near the return spring.

[0020] In one embodiment, an auxiliary collection component is also included, disposed on the inclined frame. The auxiliary collection component is used to limit the position of the waste power battery. The auxiliary collection component includes: a support plate fixed to the inclined frame; a limiting curtain fixed to the support plate; and two arc-shaped strips fixed to the inner side of the inclined frame, with the upper sides of the two arc-shaped strips contacting the limiting curtain.

[0021] In one embodiment, a cushioning pad is also included, which is fixed to the slanted frame.

[0022] The beneficial effects are as follows: 1. Workers place a certain amount of waste power batteries into the supporting circular frame through the feeding frame. Then, the workers start the drive motor. The output shaft of the drive motor drives the rotating shaft and the small spur gear to rotate clockwise. The clockwise rotation of the small spur gear drives the transmission spur gear to rotate counterclockwise. The counterclockwise rotation of the transmission spur gear drives the spur gear ring, screening ring, small limit frame, medium limit frame, large limit frame, and limit ring to rotate counterclockwise. The waste power batteries in the supporting circular frame fall downwards through the small limit frame, medium limit frame, and large limit frame in order of size from smallest to largest. The waste power batteries fall onto the inclined frame and then fall downwards along the inclined frame. Finally, the waste power batteries fall downwards through the three discharge troughs on the multi-trough discharge frame in order of size from smallest to largest. Workers collect the waste power batteries falling downwards through the three discharge troughs on the multi-trough discharge frame and sort them according to size, which facilitates the subsequent recycling of waste power batteries of different sizes and thus improves the recycling efficiency of waste power batteries.

[0023] 2. When the transmission spur gear reverses and drives the screening ring to reverse, some impurities in the support frame fall onto the inclined frame through the discharge groove, small limit frame, medium limit frame and large limit frame on the screening ring. Some impurities pass through the through groove on the inclined frame and fall onto the impurity frame, and then are discharged along the impurity frame. Workers collect the impurities, thereby quickly removing some impurities from the waste power battery and reducing the interference of impurities on the subsequent recycling of waste power batteries.

[0024] 3. The rotating shaft rotates clockwise, causing the rotating frame and the turning ring to rotate clockwise. The turning ring rotates clockwise, pushing some of the waste power batteries in the lower layer to move, while some of the waste power batteries in the upper layer fall downwards and come into contact with the screening ring. As the turning ring rotates clockwise, it continuously turns over the waste power batteries in the support circular frame. This allows the screening ring, small limit frame, medium limit frame, and large limit frame to still efficiently sort the waste power batteries even when the support circular frame is filled with a large number of waste power batteries, and to still efficiently remove impurities from the waste power batteries. This results in more efficient sorting of waste power batteries. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Example 1: A high-efficiency sorting and recycling device for power batteries, such as Figures 1-9 As shown, it includes:

[0037] Main support 1;

[0038] The drive motor 2 is bolted to the upper part of the main bracket 1;

[0039] The feed frame 3 is bolted to the upper part of the main support 1;

[0040] Rotary shaft 31 is rotatably connected to the upper part of main support 1. One end of rotary shaft 31 is fixedly connected to the output shaft of drive motor 2. Rotary shaft 31 passes through feed frame 3.

[0041] The supporting circular frame 4 is rotatably connected between the rotating shaft 31 and the feeding frame 3;

[0042] Screening ring 5 is rotatably connected to the outside of support frame 4, and multiple waste discharge grooves are opened on screening ring 5;

[0043] The discharge assembly is located on the main support 1 and is used to discharge waste power batteries.

[0044] The sorting component is located on the screening ring 5 and is used to sort waste power batteries.

[0045] An auxiliary adjustment component is located on the main support 1. The auxiliary adjustment component is used to adjust the position of the multi-slot discharge frame 55.

[0046] The discharge assembly includes: a sloping frame 51, which is slidably connected to the middle of the main support 1, and has several through slots; a return spring 511 is connected to the main support 1 via a hook; a baffle 52, which is welded to the lower part of the sloping frame 51; a guide seat 53, which is bolted to the lower part of the main support 1; a transmission frame 54, which is slidably connected to the guide seat 53; a multi-slot discharge frame 55, which is bolted to one side of the transmission frame 54, and has three discharge slots; and an impurity frame 56, which is bolted to the transmission frame 54.

[0047] The sorting assembly includes: three small limit frames 61, bolted to the screening ring 5; three medium limit frames 62, bolted to the screening ring 5; three large limit frames 63, bolted to the screening ring 5; a small spur gear 65, connected to the rotating shaft 31 via a flat key; a support rod 66, bolted to the upper part of the main support 1, and fixedly connected to the support circular frame 4; a transmission spur gear 67, rotatably connected to the support rod 66, meshing with the small spur gear 65; and a spur gear ring 68, welded to one side of the screening ring 5, meshing with the transmission spur gear 67.

[0048] The auxiliary adjustment components include: a limiting ring 71, welded to the outside of the screening ring 5, the limiting ring 71 having an inner arc surface, a middle arc surface and an outer arc surface; a guide frame 72, welded to the main support 1; a lifting frame 73, slidably connected to the guide frame 72; a helical spring 74, the guide frame 72 and the lifting frame 73 being connected by a hook; a transmission push frame 75, bolted to the bottom of the lifting frame 73, the transmission push frame 75 having a transmission groove; and a support rod 76, welded to one side of the transmission frame 54, the support rod 76 being located in the transmission groove on the transmission push frame 75.

[0049] First, the lifting frame 73 contacts the inner arc surface of the limiting ring 71. The discharge slot closest to the transmission frame 54 on the multi-slot discharge frame 55 is located diagonally below the inclined frame 51. The worker puts a certain amount of waste power batteries into the supporting circular frame 4 through the feeding frame 3. Then, the worker starts the drive motor 2. The output shaft of the drive motor 2 drives the rotating shaft 31 and the small spur gear 65 to rotate clockwise. The clockwise rotation of the small spur gear 65 drives the transmission spur gear 67 to rotate counterclockwise. The counterclockwise rotation of the transmission spur gear 67 drives the spur gear ring 68, the screening ring 5, the small limiting frame 61, the middle limiting frame 62, the large limiting frame 63, and the limiting ring 71 to rotate counterclockwise. When the small limiting frame 61 rotates to below the supporting circular frame 4 and separates from the supporting circular frame 4, the smaller waste power batteries in the supporting circular frame 4 pass through the small limiting frame 61. Smaller used power batteries fall downwards onto the inclined frame 51, then continue falling down the inclined frame 51, and finally fall down through the discharge chute closest to the transmission frame 54 on the multi-groove discharge frame 55. Workers collect the smaller used power batteries falling down through the discharge chute closest to the transmission frame 54 on the multi-groove discharge frame 55. Then, the transmission spur gear 67 continues to reverse, driving the spur gear ring 68, screening ring 5, small limit frame 61, medium limit frame 62, large limit frame 63, and limit ring 71 to continue to reverse. The limit ring 71 squeezes the lifting frame 73 and the transmission push frame 75 to move downwards. The lifting frame 73 contacts the middle arc surface on the limit ring 71, and the spiral spring 74 is stretched. The transmission push frame 75 moves downwards, squeezing the support rod 76, the transmission frame 54, and the multi-groove discharge frame 55. The discharge frame 55 and impurity frame 56 move, causing the middle discharge trough of the multi-trough discharge frame 55 to be located diagonally below the inclined frame 51. Medium-sized waste power batteries fall downwards through the limiting frame, inclined frame 51, and the middle discharge trough of the multi-trough discharge frame 55. Workers collect the medium-sized waste power batteries falling downwards from the middle discharge trough of the multi-trough discharge frame 55. Then, the transmission spur gear 67 continues to reverse, driving the spur gear ring 68, screening ring 5, small limiting frame 61, medium limiting frame 62, large limiting frame 63, and limiting ring 71 to continue to reverse. The limiting ring 71 again squeezes the lifting frame 73 and transmission push frame 75 downwards. The lifting frame 73 contacts the outer arc surface on the limiting ring 71, and the transmission push frame 75 moves downwards, squeezing the support rod 76 and transmission frame 5. 4. The multi-slot discharge frame 55 and the impurity frame 56 move, so that the discharge slot furthest from the transmission frame 54 on the multi-slot discharge frame 55 is located diagonally below the inclined frame 51. Larger waste power batteries fall downwards through the limiting frame, the inclined frame 51, and the discharge slot furthest from the transmission frame 54 on the multi-slot discharge frame 55. Workers collect the larger waste power batteries falling downwards from the discharge slot furthest from the transmission frame 54 on the multi-slot discharge frame 55. Finally, the transmission spur gear 67 continues to reverse, driving the spur gear ring 68, the screening ring 5, the small limiting frame 61, the medium limiting frame 62, the large limiting frame 63, and the limiting ring 71 to continue to reverse and reset. The lifting frame 73 separates from the outer arc surface on the limiting ring 71, and the spiral spring 74 rebounds, driving the lifting frame 73 and the transmission push frame 75 to move upwards and reset.The lifting frame 73 re-engages with the inner arc surface of the limiting ring 71, and the transmission pusher 75 moves upward to compress the support rod 76. The transmission frame 54, multi-groove discharge frame 55, and impurity frame 56 then move in the opposite direction to reset. The worker shuts off the drive motor 2, thus sorting the waste power batteries according to size. This facilitates subsequent recycling of waste power batteries of different sizes, thereby improving the recycling efficiency of waste power batteries.

[0050] When the spur gear 67 reverses, driving the spur gear ring 68, screening ring 5, small limit frame 61, medium limit frame 62, large limit frame 63 and limit ring 71 to reverse, some impurities in the support circular frame 4 fall onto the inclined frame 51 through the discharge groove on the screening ring 5, the small limit frame 61, the medium limit frame 62 and the large limit frame 63. Some impurities pass through the through groove on the inclined frame 51 and fall onto the impurity frame 56, and are then discharged along the impurity frame 56. Workers collect the impurities, thereby quickly removing some impurities from the waste power battery and reducing the interference of impurities on the subsequent recycling of waste power batteries.

[0051] Example 2: Based on Example 1, such as Figure 5 As shown, it also includes a flipping assembly, which is mounted on the rotating shaft 31. The flipping assembly is used to flip the used power batteries. The flipping assembly includes: two rotating frames 81 welded to the rotating shaft 31; and a flipping ring 82 welded between the two rotating frames 81.

[0052] When the output shaft of the drive motor 2 drives the rotating shaft 31 and the small spur gear 65 to rotate clockwise, the rotating shaft 31 drives the rotating frame 81 and the turning ring 82 to rotate clockwise. The turning ring 82 pushes some of the waste power batteries in the lower layer to move, and some of the waste power batteries in the upper layer fall down and contact the screening ring 5. Thus, when the turning ring 82 rotates clockwise, it continuously turns the waste power batteries in the support frame 4. Even when the support frame 4 is filled with a large number of waste power batteries, the screening ring 5, the small limit frame 61, the middle limit frame 62 and the large limit frame 63 can still efficiently sort the waste power batteries and still efficiently remove impurities from the waste power batteries. In this way, the waste power batteries are sorted more efficiently.

[0053] Example 3: Based on Example 2, such as Figure 2 , Figure 4 and Figure 8 As shown, it also includes a screening auxiliary component, which is disposed on the rotating shaft 31. The screening auxiliary component is used to shake the inclined frame 51. The screening auxiliary component includes: a support plate 91, which is welded to the rotating shaft 31; several protrusions 92, which are welded to the support plate 91; and a pusher 93, which is fixed to the side of the inclined frame 51 near the return spring 511.

[0054] When the output shaft of the drive motor 2 drives the rotating shaft 31 and the small spur gear 65 to rotate clockwise, the rotating shaft 31 drives the support plate 91 and the protrusion 92 to rotate clockwise. Several protrusions 92 rotate clockwise and successively squeeze the push frame 93 and the inclined frame 51 to move. When the protrusion 92 separates from the push frame 93, the return spring 511 rebounds and drives the inclined frame 51 and the push frame 93 to move in the opposite direction to reset. This process is repeated, and the inclined frame 51 can vibrate rapidly, so that impurities can pass through the through groove on the inclined frame 51 more efficiently, thereby removing impurities from the waste power battery more fully and further reducing the interference of impurities on the subsequent recycling of waste power batteries.

[0055] Example 4: Based on Example 3, such as Figure 1 , Figure 6 and Figure 7 As shown, it also includes an auxiliary collection component, which is disposed on the inclined frame 51. The auxiliary collection component is used to limit the waste power battery. The auxiliary collection component includes: a support plate 101, which is welded to the inclined frame 51; a limiting curtain 102, which is fixed to the support plate 101; and two arc-shaped strips 103, which are welded to the inner side of the inclined frame 51. The upper side of the two arc-shaped strips 103 contacts the limiting curtain 102.

[0056] When the used power batteries move downward along the inside of the inclined frame 51 under their own gravity, if there are stacks of used power batteries, the used power batteries at the top will come into contact with the limiting curtain 102. The limiting curtain 102 can limit the used power batteries, so that the used power batteries will not fall into the discharge trough of the multi-trough discharge frame 55 in the stacked state, making it smoother to fall into the multi-trough discharge frame 55 and reducing the chance of blockage during the collection of used power batteries.

[0057] Example 5: Based on Example 4, such as Figure 6 As shown, it also includes a buffer pad 11, which is fixed to the inclined frame 51. The buffer pad 11 is used to buffer the waste power battery.

[0058] As the used power battery falls downwards onto the buffer pad 11 through the small limit frame 61, the medium limit frame 62, and the large limit frame 63, the buffer pad 11 can cushion the used power battery, thereby protecting it and preserving its integrity.

[0059] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
