Description

Technical Field

[0001] This invention relates to the field of battery cell recycling technology, and in particular to a recycling and processing equipment for waste lithium battery cells. Background Technology

[0002] Against the backdrop of the rapid development of the new energy vehicle industry, vehicles powered by new energy sources such as plug-in hybrid and pure electric vehicles are gradually replacing traditional fuel vehicles. As the core energy storage component of these new energy vehicles, the demand and volume of retired power lithium batteries have experienced explosive growth. How to environmentally and efficiently dispose of retired power lithium batteries and achieve the recycling of their valuable metal resources has become a crucial aspect concerning the green and sustainable development of the new energy vehicle industry. The core unit for energy storage and release in lithium batteries is the "cell." Under professional and safe dismantling conditions, the core components of the cell include the positive electrode, negative electrode, and separator. The positive electrode, after a series of processes including aluminum foil stripping, crushing, sieving, and impurity removal, yields the positive electrode active material powder, "black powder." This black powder contains high-value metals such as cobalt, nickel, lithium, and iron, making it a key area for resource recycling.

[0003] The positive electrode sheet obtained after disassembling the battery cell is sheet-like, specifically consisting of an aluminum foil base and a layer of positive electrode active material coated on the surface. It is relatively thin, lightweight, and flexible. Currently, the positive electrode sheet is processed on-site using a process of crushing followed by screening. The positive electrode sheet is first fed into the top inlet, and the hammer-type crusher inside the equipment rotates at high speed, crushing the positive electrode sheet through impact, shearing, and other actions. After being crushed, the material is filtered through a sieve plate, and the material that meets the particle size requirements falls into the outlet. The outlet is connected to a negative pressure pipeline, and the screened material (positive electrode active material powder "black powder" and aluminum foil fragments) is drawn to the subsequent processing steps by negative pressure suction.

[0004] However, in on-site operations, the above process has the following problems: the positive electrode sheets that are not fully crushed are mostly long strips of aluminum foil fragments or long strips of aluminum foil fragments wrapped with active materials to form clumps. These materials are easy to get tangled around the edges of the screen mesh or accumulate on the screen surface, forming bridging blockages. This prevents the screened material from falling smoothly into the discharge port. Furthermore, when the screen is blocked, the negative pressure suction not only fails to assist in feeding, but may also further compress the uncrushed flaky material at the screen, exacerbating the blockage. This increases the internal pressure of the crusher, causing equipment overload, motor overheating, and other malfunctions. In severe cases, the machine needs to be shut down for cleaning, reducing the efficiency of cell production and recycling. Summary of the Invention

[0005] The purpose of this invention is to provide a lithium battery waste cell recycling and processing equipment, which can process long strip-shaped aluminum foil fragments or clumps of material wrapped around a screen plate, thereby improving the efficiency of cell recycling and processing.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a lithium battery waste cell recycling and processing equipment, including a frame, a processing box fixed on the frame, a processing inlet and a processing outlet respectively provided at the top and bottom of the processing box, a processing shaft rotatably connected inside the processing box, a hammer fixed on the processing shaft, baffles fixed on the side walls of the processing box, an arc-shaped screen plate slidably arranged between the baffles on both sides and located below the hammer, a control cavity is enclosed between the baffles and the inner wall of the processing box, a control component for controlling the reciprocating movement of the screen plate is provided in the control cavity, and a drive component for controlling the rotation of the processing shaft is provided outside the processing box.

[0007] By adopting the above technical solution, the positive electrode sheet of the battery cell to be processed is put into the processing box from the processing inlet. The drive component controls the processing shaft and hammer to rotate, which realizes multiple actions such as impact and shearing on the positive electrode sheet located between the hammer and the screen plate, thereby crushing the positive electrode sheet. During this process, the control component controls the screen plate to move back and forth between the two side baffles. The shaking assists the feeding and reduces the risk of screen hole blockage. By tearing the long strip aluminum foil fragments and promoting the shearing action between the long strip aluminum foil fragments and the hammer, the amount of long strip aluminum foil fragments wrapped around the screen plate or the clumps of material formed by long strip aluminum foil fragments carrying active materials is further reduced, thereby improving the efficiency of battery cell recycling.

[0008] A further configuration of the present invention is as follows: the processing box includes a lower box body fixed to the frame and an upper box body hinged to the lower box body; cylinders are hinged to the two side walls of the lower box body; the output ends of the cylinders on both sides are respectively hinged to the two side walls of the upper box body; sleeves are fixed to the top two sides of the lower box body; the processing shaft is rotatably connected between the two sleeves; and a slot adapted to the sleeve is provided at the bottom of the upper box body.

[0009] By adopting the above technical solution, the upper box is rotated relative to the lower box by a cylinder, thereby opening the inside of the processing box and allowing for further cleaning of the inside of the processing box.

[0010] A further configuration of the present invention is as follows: the drive assembly includes a drive motor fixedly mounted on the frame, a first synchronous pulley is fixed at one end of the processing shaft, a second synchronous pulley is fixed at the output end of the drive motor, and a first synchronous belt is sleeved between the first synchronous pulley and the second synchronous pulley.

[0011] By adopting the above technical solution, the second synchronous pulley is driven to rotate by the drive motor, thereby driving the first synchronous pulley and the processing shaft to rotate through the first synchronous belt. The rotation of the processing shaft and the hammer blades achieves multiple effects such as impact and shearing on the positive electrode sheet located between the hammer blades and the sieve plate.

[0012] A further feature of the present invention is that the top of the baffle is provided with an arc-shaped groove adapted to the curvature of the sieve plate, and the bottom of the sieve plate is fixed with a protrusion that slides within the arc-shaped groove.

[0013] By adopting the above technical solution, the sieve plate slides along the arc direction between the two side baffles through the protrusions and arc grooves, reducing the risk of sieve plate hole blockage and improving the efficiency of positive electrode sheet breakage processing.

[0014] A further configuration of the present invention is as follows: the control assembly includes two control shafts rotatably connected to the processing box, the two control shafts are fixed with mutually meshing first gears located in the control cavity, a plurality of control rods are fixed around the center of the first gears on their sidewalls, the processing box is rotatably connected to a transmission shaft, the transmission shaft is fixed with a second gear meshing with the control rods, the plurality of control rods on the two first gears are staggered, such that when the control rod on one of the first gears meshes with the second gear and controls the second gear to rotate, the control rod on the other first gear immediately meshes with the second gear and controls the second gear to rotate in the opposite direction, and a first arc-shaped rack meshing with the second gear is fixed at the bottom of the sieve plate.

[0015] By adopting the above technical solution, when one of the first gears rotates, the two first gears rotate in opposite directions due to mutual meshing. When the control rod on one of the first gears meshes with the second gear and controls the second gear to rotate in one direction, the control rod on this first gear disengages from the second gear, and the control rod on the other first gear immediately meshes with the second gear, controlling the second gear to rotate in the opposite direction. This process is repeated to realize the reciprocating rotation of the second gear, thereby driving the first arc-shaped rack and the screen plate to move back and forth, causing the screen plate to slide back and forth in the arc direction between the two side baffles.

[0016] A further configuration of the present invention is as follows: a third synchronous pulley is fixed to one end of the processing shaft extending out of the processing box, and a fourth synchronous pulley is fixed to one end of one of the control shafts that rotatably extends out of the processing box, and a second synchronous belt is sleeved between the third synchronous pulley and the fourth synchronous pulley.

[0017] By adopting the above technical solution, when the processing shaft rotates, the shaft is driven to rotate synchronously through the third synchronous pulley, the fourth synchronous pulley, and the second synchronous belt, so that the hammer and filter plate can work simultaneously, thereby improving the processing efficiency of the positive electrode sheet of the battery cell.

[0018] A further provision of the present invention is that: a connecting shaft is provided inside the processing box below the sieve plate, a scraper is fixed on the connecting shaft along its axial direction, the scraper is configured as a plurality of scrapers distributed circumferentially along the connecting shaft, and a scraping assembly is provided inside the control cavity to control the movement and rotation of the connecting shaft along the inner cavity of the processing box.

[0019] By adopting the above technical solution, the scraping assembly controls the connecting shaft and scraper to move along the bottom of the screen plate. During the movement, the connecting shaft and scraper rotate to perform secondary kneading and scraping on the long strips of aluminum foil fragments accumulated on the screen plate. This promotes further dissociation of the blockage from the screen plate, thereby further reducing material residue on the screen plate. The scraper can also throw the dissociated material to the processing outlet, facilitating the smooth discharge of the crushed positive electrode sheet. The hammers and scrapers set at the top and bottom of the screen plate work together to significantly improve the automation level and processing efficiency of the lithium battery positive electrode sheet recycling pretreatment process.

[0020] A further configuration of the present invention is as follows: the scraping assembly includes a reciprocating screw rotatably connected to the processing box, the reciprocating screw being threadedly connected to a connecting rod sliding on the baffle, the connecting rod having a groove and a movable rod slidably connected thereto, a spring being fixed between one end of the movable rod located in the groove and the inner wall of the groove, the baffle having an arc-shaped through hole, the bending angle of the arc-shaped through hole being the same as the bending angle of the sieve plate, and the two ends of the connecting shaft passing through the arc-shaped through holes on both sides respectively and being rotatably connected between the movable rods on both sides.

[0021] By adopting the above technical solution, the reciprocating screw rotates, pushing the connecting rod, movable rod, connecting shaft and scraper to move back and forth along the baffle in the processing box. During the movement of the connecting rod, the connecting shaft rises and falls under the guidance of the arc-shaped through hole, so that the scraper can always be in contact with the bottom of the sieve plate to process the positive electrode fragments blocked at the sieve plate.

[0022] A further feature of the present invention is that: the baffle is fixed with a second arc-shaped rack located in the control cavity, the bending angle of the second arc-shaped rack is the same as the bending angle of the arc-shaped through hole, and the two ends of the connecting shaft are fixed with third gears that mesh with the second arc-shaped rack.

[0023] By adopting the above technical solution, during the reciprocating movement of the connecting rod, movable rod, connecting shaft, and scraper along the baffle inside the processing box, the third gear rotates due to meshing with the second arc-shaped rack, thereby causing the connecting shaft and multiple scrapers to rotate, and to perform secondary kneading and scraping on the long strips of aluminum foil fragments accumulated on the sieve plate.

[0024] A further configuration of the present invention is as follows: a first bevel tooth is fixed to one end of the reciprocating screw extending out of the processing box; a rotating shaft is rotatably connected to the outside of the processing box; a second bevel tooth that meshes with the first bevel tooth is fixed to one end of the rotating shaft; a fifth synchronous pulley is fixed to the other end; a sixth synchronous pulley is fixed to the control shaft; and a third synchronous belt is sleeved between the second synchronous pulley and the sixth synchronous pulley.

[0025] By adopting the above technical solution, the control shaft, processing shaft and rotating shaft are made to rotate synchronously through the second synchronous pulley, the sixth synchronous pulley and the third synchronous belt. When the rotating shaft rotates, the reciprocating screw is driven to rotate through the first bevel tooth and the second bevel tooth, so as to realize the coordinated operation of the hammer, screen plate and scraper, which can reduce energy consumption and improve resource recycling efficiency.

[0026] The beneficial effects of this invention are:

[0027] 1. The control component controls the screen plate to move back and forth between the two side baffles. The shaking assists in feeding, reducing the risk of screen plate hole blockage. By tearing long strips of aluminum foil and promoting the shearing action between the long strips of aluminum foil and the hammer, the amount of long strips of aluminum foil fragments wrapped around the screen plate or the amount of clumps of active materials formed by long strips of aluminum foil fragments is further reduced, thereby improving the efficiency of battery cell recycling. The efficient recycling of lithium battery cells can reduce dependence on external mineral resources and support the continuous production of new energy vehicles.

[0028] 2. The scraping assembly controls the connecting shaft and scraper to move along the bottom of the screen plate. During the movement, the connecting shaft and scraper rotate to perform secondary kneading and scraping on the long strips of aluminum foil fragments accumulated on the screen plate. This can promote further separation of the blockage from the screen plate, thereby further reducing the material residue on the screen plate. The scraper can also throw the separated material to the processing outlet, promoting the smooth discharge of the crushed positive electrode sheet.

[0029] 3. Through the coordinated action of the upper and lower hammers and scrapers on the sieve plate, the dead corners of sieve plate entanglement and blockage can be eliminated, which can significantly improve the automation level and processing efficiency of the lithium battery cathode sheet recycling pretreatment process.

[0041] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] Example 1: A lithium battery waste cell recycling and processing equipment, such as... Figure 1-3As shown, the machine includes a frame 1, a processing box 2 fixed on the frame 1, a processing inlet 3 and a processing outlet 4 respectively at the top and bottom of the processing box 2, a processing shaft 5 rotatably connected inside the processing box 2, a hammer blade 6 fixed on the processing shaft 5, baffles 7 fixed on the two side walls of the processing box 2, an arc-shaped screen plate 8 slidably arranged between the two side baffles 7 and located below the hammer blade 6, the baffles 7 and the inner wall of the processing box 2 enclose a control cavity, a control component 9 for controlling the reciprocating movement of the screen plate 8 is arranged in the control cavity, and a drive component 10 for controlling the rotation of the processing shaft 5 is arranged outside the processing box 2. The positive electrode sheet of the battery cell to be processed is put into the processing box 2 through the processing inlet 3. The drive component 10 controls the processing shaft 5 and the hammer 6 to rotate, so as to realize multiple actions such as impact and shearing on the positive electrode sheet located between the hammer 6 and the screen plate 8, thereby crushing the positive electrode sheet. During this process, the control component 9 controls the screen plate 8 to move back and forth between the two side baffles 7. The shaking assists the material feeding and reduces the risk of screen hole blockage of the screen plate 8. The crushed material falls into the processing outlet 4, which is connected to the negative pressure pipeline. The negative pressure suction force draws the screened material (positive electrode active material powder "black powder" and aluminum foil fragments) to the subsequent processing process.

[0043] like Figure 1 As shown, the processing box 2 includes a lower box 202 fixed to the frame 1 and an upper box 201 hinged to the lower box 202. Cylinders 11 are hinged to both sides of the lower box 202, and the output ends of the cylinders 11 are respectively hinged to the two sides of the upper box 201. Sleeves 12 are fixed to both sides of the top of the lower box 202, and the processing shaft 5 is rotatably connected between the two sleeves 12. The bottom of the upper box 201 has a slot suitable for the sleeves 12. By pushing the upper box 201 relative to the lower box 202 with the cylinders 11, the interior of the processing box 2 is opened, allowing for further cleaning of the interior.

[0044] like Figure 2 As shown, the drive assembly 10 includes a drive motor 101 fixedly mounted on the frame 1, a first synchronous pulley 102 fixed to one end of the processing shaft 5, a second synchronous pulley 103 fixed to the output end of the drive motor 101, and a first synchronous belt 104 sleeved between the first synchronous pulley 102 and the second synchronous pulley 103. The drive motor 101 drives the second synchronous pulley 103 to rotate, thereby causing the first synchronous pulley 102 and the processing shaft 5 to rotate via the first synchronous belt 104. The rotation of the processing shaft 5 and the hammer 6 performs various actions such as impact and shearing on the positive electrode sheet located between the hammer 6 and the sieve plate 8.

[0045] Furthermore, the top of the baffle 7 is provided with an arc-shaped groove adapted to the curvature of the sieve plate 8, and the bottom of the sieve plate 8 is fixed with a protrusion that slides within the arc-shaped groove. The sieve plate 8 slides along the arc direction between the two baffles 7 via the protrusion and the arc-shaped groove, reducing the risk of sieve hole clogging and improving the efficiency of positive electrode sheet breakage processing.

[0046] like Figure 3-7 As shown, the control assembly 9 includes two control shafts 901 rotatably connected to the processing box 2. The two control shafts 901 are fixed with meshing first gears 902 located in the control cavity. Multiple control levers 903 are fixed around the center of the side wall of the first gears 902. The processing box 2 is rotatably connected to a transmission shaft 904. The transmission shaft 904 is fixed with a second gear 905 that meshes with the control levers 903. The multiple control levers 903 on the two first gears 902 are staggered so that when the control lever 903 on one of the first gears 902 meshes with the second gear 905 and controls the second gear 905 to rotate, the control lever 903 on the other first gear 902 immediately meshes with the second gear 905 and controls the second gear 905 to rotate in the opposite direction. A first arc-shaped rack 906 that meshes with the second gear 905 is fixed at the bottom of the sieve plate 8. When one of the first gears 902 rotates, the two first gears 902 rotate in opposite directions due to their meshing. When the control rod 903 on one of the first gears 902 meshes with the second gear 905 and controls the second gear 905 to rotate in one direction, the control rod 903 on this first gear 902 disengages from the second gear 905, and the control rod 903 on the other first gear 902 immediately meshes with the second gear 905, controlling the second gear 905 to rotate in the opposite direction. This process is repeated to achieve the reciprocating rotation of the second gear 905, thereby driving the first arc-shaped rack 906 and the sieve plate 8 to move back and forth, causing the sieve plate 8 to slide back and forth in the arc direction between the two side baffles 7.

[0047] like Figure 2 , 6 As shown, a third synchronous pulley 13 is fixed to one end of the processing shaft 5 extending out of the processing box 2. A fourth synchronous pulley 907 is fixed to the end of a control shaft 901 that rotates out of the processing box 2. A second synchronous belt 14 is sleeved between the third synchronous pulley 13 and the fourth synchronous pulley 907. When the processing shaft 5 rotates, the control shaft 901 is driven to rotate synchronously through the third synchronous pulley 13, the fourth synchronous pulley 907, and the second synchronous belt 14, enabling the hammer blades 6 and the filter plate to operate simultaneously, thus improving the processing efficiency of the positive electrode sheet of the battery cell.

[0048] like Figure 3 , 5 As shown in Figure 8, a connecting shaft 15 is installed inside the processing box 2, located below the sieve plate 8. A scraper 16 is fixed to the connecting shaft 15 along its axial direction. Multiple scrapers 16 are arranged circumferentially along the connecting shaft 15. A scraping assembly 17 is installed in the control chamber to control the movement and rotation of the connecting shaft 15 within the processing box 2. The scraping assembly 17 controls the connecting shaft 15 and the scrapers 16 to move along the bottom of the sieve plate 8. During this movement, the connecting shaft 15 and the scrapers 16 rotate, performing secondary kneading and scraping on the long strips of aluminum foil accumulated on the sieve plate 8. This promotes further disintegration of the blockage from the sieve plate 8, thereby further reducing material residue on the sieve plate 8.

[0049] like Figure 9 As shown, the scraping assembly 17 includes a reciprocating screw 171 rotatably connected to the processing box 2. The reciprocating screw 171 is threadedly connected to a connecting rod 172 that slides on the baffle 7. The connecting rod 172 has a groove and a movable rod 173 is slidably connected to it. A spring 174 is fixed between one end of the movable rod 173 located in the groove and the inner wall of the groove. The baffle 7 has an arc-shaped through hole 175. The bending angle of the arc-shaped through hole 175 is the same as the bending angle of the screen plate 8. The two ends of the connecting shaft 15 pass through the arc-shaped through holes 175 on both sides respectively and are rotatably connected between the movable rods 173 on both sides. The reciprocating screw 171 rotates, pushing the connecting rod 172, movable rod 173, connecting shaft 15 and scraper 16 to reciprocate along the baffle 7 within the processing box 2. During the movement of the connecting rod 172, the connecting shaft 15 rises and falls under the guidance of the arc-shaped through hole 175, and the movable rod 173 also rises and falls within the slide groove of the connecting rod 172. Since the bending angle of the arc-shaped through hole 175 is the same as the bending angle of the sieve plate 8, the scraper 16 can always be in contact with the bottom of the sieve plate 8. With the back-and-forth movement of the sieve plate 8, the blocking material located between the scraper 16 and the sieve plate 8 can be sheared, and the positive electrode fragments blocking the bottom of the sieve plate 8 can be processed.

[0050] like Figure 9 As shown, a second arc-shaped rack 176 is fixed in the control cavity of the baffle 7. The bending angle of the second arc-shaped rack 176 is the same as the bending angle of the arc-shaped through hole 175. A third gear 177 that meshes with the second arc-shaped rack 176 is fixed at both ends of the connecting shaft 15. During the reciprocating movement of the connecting rod 172, the movable rod 173, the connecting shaft 15, and the scraper 16 along the baffle 7 in the processing box 2, the third gear 177 rotates due to meshing with the second arc-shaped rack 176, thereby rotating the connecting shaft 15 and the multiple scrapers 16, and performing secondary kneading and scraping on the long strips of aluminum foil fragments accumulated on the sieve plate 8.

[0051] like Figure 6 As shown, a first bevel tooth 178 is fixed to one end of the reciprocating screw 171 extending out of the processing box 2. A rotating shaft 18 is rotatably connected to the outside of the processing box 2. A second bevel tooth 19 that meshes with the first bevel tooth 178 is fixed to one end of the rotating shaft 18, and a fifth synchronous pulley 20 is fixed to the other end. A sixth synchronous pulley 21 is fixed to the control shaft 901. A third synchronous belt 22 is sleeved between the second synchronous pulley 103 and the sixth synchronous pulley 21. Through the second synchronous pulley 103, the sixth synchronous pulley 21, and the third synchronous belt 22, the control shaft 901, the processing shaft 5, and the rotating shaft 18 rotate synchronously. When the rotating shaft 18 rotates, the first bevel tooth 178 and the second bevel tooth 19 drive the reciprocating screw 171 to rotate, realizing the coordinated operation of the hammer 6, the sieve plate 8, and the scraper 16, thereby reducing energy consumption.
