Description

Technical Field

[0001] This utility model relates to the field of lithium iron phosphate battery recycling, specifically a recycling and dismantling device for lithium iron phosphate power batteries. Background Technology

[0002] Lithium iron phosphate (LFP) batteries are a type of lithium-ion rechargeable battery, currently mainly used in the power battery field. They offer many advantages, exhibiting excellent performance in cycle life, safety, and operating temperature range, thus finding widespread application in new energy vehicles and energy storage. When recycling LFP batteries, a recycling and dismantling device is required. The "Recycling and Dismantling Device for Lithium Iron Phosphate Power Batteries" disclosed in application number "202322877875.7" represents an increasingly mature technology. It features a "vibration structure; because the middle depth of the guide groove is greater than the depths at both ends, the guide block located in the guide groove can drive the screening frame to rise and fall." This allows the screening frame to vibrate up and down, enabling more lithium iron phosphate powder to fall smoothly into the screening holes. The vibrating screening frame also gets closer to the teeth of the crushing gear shaft, further crushing larger waste materials. However, this dismantling device has the following drawbacks: While the vibrating structure, combined with the guide groove and screening frame, can indeed screen lithium iron phosphate battery fragments, the simple screening structure can lead to blockages when the fragments accumulate. Therefore, it is necessary to provide a recycling device that can perform vibratory screening and improve screening smoothness. The "Recycling and Dismantling Device for Lithium Iron Phosphate Power Batteries" disclosed in application number "202022207379.3" is also an increasingly mature technology. This invention uses a feeding box, a sealing pipe, and a guide plate to guide the batteries after they enter, preventing them from accumulating and entering the working chamber. A connecting block, along with a fan and air inlet pipe, collects toxic gases generated during battery dismantling. A motor, in conjunction with a crushing cylinder, enables battery dismantling, saving time and effort and eliminating the need for direct contact by workers. A support frame, along with a chassis, allows for easy operation of the dismantling device. The device provides support and fixation to prevent instability during disassembly. A collection box, along with a movable rod and pull handle, secures the box, preventing it from falling and preventing battery debris from sticking to the inner wall of the work chamber, making battery debris collection more convenient, time-saving, and labor-saving. However, this disassembly device has the following drawbacks: while the guide plates effectively unload the batteries, the overlapping structure of the two guide plates may cause blockages during unloading. Therefore, it is necessary to provide a disassembly device that can stably unload batteries, avoid blockages, and improve battery disassembly efficiency. Utility Model Content

[0003] The present invention provides a recycling and dismantling device for lithium iron phosphate power batteries, which aims to solve the problems of existing dismantling devices being inconvenient for continuous battery feeding and avoiding blockage, while the screening efficiency needs to be improved.

[0004] To achieve the above objectives, this utility model provides a recycling and dismantling device for lithium iron phosphate power batteries, including a dismantling component, a feeding component, and a screening component. The disassembly assembly includes a disassembly box, inside which two crushing rollers are rotatably connected. One end of each crushing roller is connected to a transmission gear, and one end of one of the crushing rollers is equipped with a transmission mechanism. The feeding assembly includes a feeding hopper installed on the upper end of the disassembly box. Two rotating shafts are rotatably connected inside the feeding hopper. Several feeding plates are fixedly connected to the side surfaces of the two rotating shafts. A linkage mechanism is provided between the rotating shafts and the crushing roller. The screening assembly includes a screening box installed inside the disassembly box. A base plate is fixedly connected to the lower end of the screening box. Several screening holes are opened on the surface of the base plate. A transmission arm is hinged to the lower end of the base plate. An eccentric motor is connected to one side of the transmission arm. A collection box is installed at the lower end of the screening box.

[0005] As a preferred embodiment of this utility model, the transmission mechanism includes a first synchronous pulley installed at one end of one of the crushing rollers, a servo motor installed on one side of the disassembly box, a second synchronous pulley connected to the output end of the servo motor, and a synchronous belt connected between the second synchronous pulley and the first synchronous pulley.

[0006] As a preferred embodiment of the present invention, the linkage mechanism includes a first linkage disc installed at one end of two rotating shafts, a second linkage disc connected to one end of each of the two crushing rollers, and a linkage belt connecting the first linkage disc and the second linkage disc.

[0007] As a preferred embodiment of this utility model, two connecting holes are provided at both ends of the hopper, and the two rotating shafts are rotatably connected inside the connecting holes.

[0008] As a preferred embodiment of this utility model, the lower end of the base plate is provided with a connecting screw hole, and a connecting bolt is connected to the internal thread of the connecting screw hole.

[0009] In a preferred embodiment of this utility model, a hinge seat is fixedly connected to the lower end of the connecting bolt, and a hinge shaft is fixedly connected to the upper end of the transmission arm, wherein the hinge shaft and the hinge seat are hinged to each other.

[0010] As a preferred embodiment of this utility model, the lower end of the transmission arm is provided with a mounting groove, and a bearing is installed inside the mounting groove. The output end of the eccentric motor is key-connected to the inside of the bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are: When recycling lithium iron phosphate batteries, the transmission mechanism is first activated to rotate one of the crushing rollers, which in turn rotates the transmission gears on its side surface. At this time, the two transmission gears mesh and connect, and the two crushing rollers can be controlled to rotate in opposite directions to crush and dismantle the battery. Simultaneously, as the two crushing rollers rotate, they can also rotate two second linkage discs, which, together with the linkage belt, drive two first linkage discs and two rotating shafts to rotate in opposite directions. The battery is then placed on the upper end of the two rotating shafts, and the two rotating shafts drive the feeding plate to rotate, which facilitates a stable and continuous feeding operation of the battery and avoids blockage. Compared with the dismantling device in the existing technology "A recycling and dismantling device for lithium iron phosphate power batteries", this utility model, through the above-mentioned structure, can facilitate a continuous feeding operation of the battery, avoid battery blockage, and thus improve the battery dismantling efficiency of the dismantling device. After the battery is crushed and dismantled by the crushing roller, it falls into the screening box. At this time, simply start the eccentric motor to drive the transmission arm to rotate, thereby pulling the transmission arm and the screening box above it back and forth, causing the screening box to vibrate. Small particles can be screened through several screening holes at the bottom of the screening box and finally collected by the collection box. At the same time, large particles are collected in the screening box to avoid blockage. Compared with the dismantling device in the existing technology "a recycling and dismantling device for lithium iron phosphate power batteries", this utility model, through the cooperation of the above structure, can facilitate the screening operation of battery fragments by vibration, thereby improving the dismantling efficiency of batteries.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please see Figures 1-4 This utility model provides a recycling and dismantling device for lithium iron phosphate power batteries, including a dismantling component 100, a feeding component 200, and a screening component 300. The disassembly assembly 100 includes a disassembly box 101, which has two crushing rollers 102 rotatably connected inside. One end of each crushing roller 102 is connected to a transmission gear 103, and one end of one crushing roller 102 is equipped with a transmission mechanism 104. The feeding assembly 200 includes a feeding hopper 201 installed on the upper end of the disassembly box 101. Two rotating shafts 202 are rotatably connected inside the feeding hopper 201. Several feeding plates 203 are fixedly connected to the side surfaces of the two rotating shafts 202. A linkage mechanism 204 is provided between the rotating shafts 202 and the crushing roller 102. The screening assembly 300 includes a screening box 301 installed inside the disassembly box 101. A bottom plate 302 is fixedly connected to the lower end of the screening box 301. A plurality of screening holes 303 are opened on the surface of the bottom plate 302. A transmission arm 304 is hinged to the lower end of the bottom plate 302. An eccentric motor 305 is connected to one side of the transmission arm 304. A collection box 306 is installed at the lower end of the screening box 301.

[0016] In one specific embodiment, the dismantling component 100, in conjunction with the feeding component 200, not only facilitates the crushing of the battery but also enables continuous and stable feeding, preventing blockages and thus improving the dismantling efficiency of the device. Simultaneously, the screening component 300 uses vibration to screen the battery fragments, improving the smoothness of the screening process. In operation, the transmission mechanism 104 is first activated, rotating one of the crushing rollers 102, which in turn rotates the transmission gear 103 on its side surface.

Then, the eccentric motor 305 is started to drive the transmission arm 304 to rotate, which can reciprocate the transmission arm 304 and the screening box 301 at its upper end, causing the screening box 301 to vibrate. Through the several screening holes 303 opened at the bottom of the screening box 301, small particles can be screened and collected by the collection box 306. At the same time, large particles are collected in the screening box 301 to avoid blockage, thereby improving the screening efficiency of the dismantling device.

[0017] Please see Figure 2 The transmission mechanism 104 includes a first synchronous pulley 1041 installed at one end of one of the crushing rollers 102, a servo motor 1042 installed on one side of the disassembly box 101, a second synchronous pulley 1043 connected to the output end of the servo motor 1042, and a synchronous belt 1044 connected between the second synchronous pulley 1043 and the first synchronous pulley 1041.

[0018] In one specific embodiment, the servo motor 1042 is started to drive the second synchronous pulley 1043 to rotate, which in turn drives the first synchronous pulley 1041 to rotate with the synchronous belt 1044. With the help of the two transmission gears 103, the two crushing rollers 102 can be controlled to rotate in opposite directions to facilitate the crushing operation of the battery.

[0019] Please see Figure 2 and Figure 3 The linkage mechanism 204 includes a first linkage disc 2041 installed at one end of two rotating shafts 202, a second linkage disc 2042 connected to one end of each of the two crushing rollers 102, and a linkage belt 2043 connecting the first linkage disc 2041 and the second linkage disc 2042.

[0020] In one specific embodiment, when the crushing roller 102 rotates, it can rotate the second linkage disk 2042, which, together with the linkage belt 2043, can rotate the first linkage disk 2041, thereby rotating the rotating shaft 202 and the feeding plate 203 on its side surface to continuously feed the battery, avoiding battery blockage.

[0021] Please see Figure 3 The hopper 201 has two connecting holes 211 at both ends, and the two rotating shafts 202 are rotatably connected inside the connecting holes 211.

[0022] In one specific embodiment, the connecting hole 211 can improve the smoothness of the rotational connection to the rotating shaft 202, thereby improving the continuous feeding efficiency of the battery.

[0023] Please see Figure 4 The bottom end of the base plate 302 is provided with a connecting screw hole 311, and a connecting bolt 312 is connected to the internal thread of the connecting screw hole 311.

[0024] In one specific embodiment, the connecting bolt 312 is threaded into the connecting bolt hole 311, thereby enhancing the connection tightness and ease of disassembly and replacement between the base plate 302 and the hinge seat 321.

[0025] Please see Figure 4 The lower end of the connecting bolt 312 is fixedly connected to a hinge seat 321, and the upper end of the transmission arm 304 is fixedly connected to a hinge shaft 322. The hinge shaft 322 and the hinge seat 321 are hinged to each other.

[0026] In one specific embodiment, the hinge shaft 322 and the hinge seat 321 are hinged to each other, thereby improving the smoothness of rotation of the transmission arm 304.

[0027] Please see Figure 4 The lower end of the transmission arm 304 is provided with a mounting groove 331, and a bearing 332 is installed inside the mounting groove 331. The output end of the eccentric motor 305 is key connected to the inside of the bearing 332.

[0028] In one specific embodiment, the presence of bearing 332 can reduce the rotational friction of eccentric motor 305, thereby improving screening smoothness.

[0029] Working principle: In use, firstly, starting the transmission mechanism 104 rotates one of the crushing rollers 102, which in turn rotates the transmission gear 103 on its side surface. The two transmission gears 103 mesh and connect, thereby controlling the two crushing rollers 102 to rotate in opposite directions to crush and disassemble the battery. This, in turn, rotates the two second linkage discs 2042, which, together with the linkage belt 2043, rotate the two first linkage discs 2041 and the two rotating shafts 202 in opposite directions. Then, the battery is placed on the upper end of the two rotating shafts 202, and the two rotating shafts 202 rotate the feeding plate 203, which facilitates the crushing and disassembly of the battery. The battery is fed in a stable and continuous manner, which avoids clogging and improves the dismantling efficiency. After the battery is crushed, it falls into the screening box 301. By starting the eccentric motor 305 to rotate the transmission arm 304, the transmission arm 304 and the screening box 301 at its upper end are pulled back and forth, causing the screening box 301 to vibrate. Small particles can be screened through several screening holes 303 at the bottom of the screening box 301 and collected by the collection box 306. At the same time, large particles are collected in the screening box 301 to avoid clogging, thus improving the screening efficiency of the dismantling device.
