Description

Technical Field

[0001] This invention belongs to the field of crushing equipment technology, and in particular relates to a waste lithium-ion battery recycling device. Background Technology

[0002] Lithium battery recycling refers to the process of recycling and processing used lithium batteries. Recycling lithium batteries is of great significance because it can recover valuable materials such as lithium, cobalt, and nickel; it can reduce environmental pollution and prevent harmful substances in used batteries from damaging soil and water bodies; it can create economic value and reduce dependence on raw materials. During the recycling of used lithium-ion batteries, in order to more easily separate various materials and improve recycling efficiency, it is necessary to crush the recycled lithium-ion batteries. For example, the crushing device for recycling used lithium-ion batteries proposed in patent publication number CN116371866A highlights the necessity of crushing used lithium-ion batteries.

[0003] To prevent residual current in waste lithium-ion batteries from causing fires during the crushing process, existing crushing equipment requires discharging the batteries before crushing. However, when there are many waste lithium-ion batteries, operators may neglect to discharge them properly. If the crushing equipment then crushes these undischarged batteries, it can cause a short circuit between the positive and negative electrodes, leading to a fire.

When crushing waste lithium-ion batteries, the crushing device will only work after a lithium-ion battery falls into the crushing device. When there is no item inside the crushing device, the crushing device will automatically stop working, thereby avoiding energy waste.

[0030] The separation and recovery assembly 29 includes a recovery cylinder 291 and a horizontal box 292. The recovery cylinder 291 is located below the feed pipe 19 and is filled with water. The horizontal box 292 is located below the recovery cylinder 291. The horizontal box 292 and the recovery cylinder 291 are fixedly connected by the same vertical pipe 30. A solenoid valve 31 is installed in the vertical pipe 30. A linear motor 32 is fixedly connected to the rear wall of the recovery cylinder 291. The moving end of the linear motor 32 is fixedly connected to a third electric push rod 33 via a bracket. The output end of the third electric push rod 33 is fixedly connected to a working motor 34 via a bending frame. The output end of the working motor 34 is fixedly connected to a mesh frame 35, which is located inside the recovery cylinder 291. The lower end of the recovery cylinder 291 is below the liquid surface. The horizontal box 292... A threaded cylinder 36 is rotatably connected to the front side wall of the transverse box 292, and a push motor 37 is fixedly connected to the front side wall of the transverse box 292. The output end of the push motor 37 is connected to the threaded cylinder 36 through a gear assembly. A threaded rod 38 is threadedly sleeved inside the threaded cylinder 36. A pusher plate 39 is fixedly connected to one end of the threaded rod 38 inside the transverse box 292.

A sealing baffle 41 is fixedly connected to the output end of the fourth electric push rod 40. The sealing baffle 41 is inserted into the transverse box 292. After the waste lithium-ion batteries are crushed, the crushed items can be automatically sorted and collected without the need for operators to sort the crushed materials, thus improving the convenience of the operators' work.

[0031] The horizontal box 292 and the recovery cylinder 291 are fixedly connected by the same return water pipe 42. The lower end of the return water pipe 42 is connected to the lower part of the rear side wall of the horizontal box 292. A one-way valve is installed in the return water pipe 42. Both the upper and lower ends of the return water pipe 42 are covered with filter screens 43, which can press a part of the water inside the horizontal box 292 back into the recovery cylinder 291.

[0032] An air pump 44 is fixedly connected to the upper side wall of the horizontal box 292. The air pump 44 is electrically connected to the PLC controller. An air outlet pipe 45 is fixedly connected to the air outlet end of the air pump 44. The lower end of the air outlet pipe 45 is connected to the upper side wall of the horizontal box 292. A one-way valve is provided in the air outlet pipe 45, which can transport all the water in the horizontal box 292 to the recovery cylinder 291.

[0033] The side wall of the horizontal box 292 is fixedly connected to a limiting rod 46. The rod wall of the threaded rod 38 is provided with a limiting groove that matches the limiting rod 46. Through the cooperation of the limiting rod 46 and the limiting groove, the threaded rod 38 is prevented from rotating, so that the threaded rod 38 can only move left and right in the horizontal direction, thereby reducing the torque of the threaded rod 38 and the push plate 39.

[0034] The operating principle of this invention is explained as follows: Waste lithium-ion batteries are placed on conveyor belt 4, whose surface is coated with marking areas. The batteries are then placed in these marking areas. An external button controls the conveyor belt 4 to move the waste lithium-ion batteries towards the mounting frame 3. When a battery moves to the first proximity switch 9, the switch detects it and, via the PLC controller, immediately stops the conveyor belt 4. The PLC controller then controls the front hydraulic cylinder 15 to move, causing the front electric gripper 16 to move closer to the battery, positioning it on both the front and rear sides. The PLC controller then controls the electric gripper 16 to operate. The battery is clamped and positioned using an electric gripper 16, aligning the positive and negative terminals of the battery with the two detection posts 7. Then, the PLC controller controls the first electric push rod 501 to move downwards to a set position, bringing the detection posts 7 into contact with the positive and negative terminals of the battery. The battery is then tested using a first voltmeter 8. When the battery is found to be depleted, the PLC controller controls the first electric push rod 501 to move upwards to the initial position. Then, the PLC controller controls the front hydraulic cylinder 15 and the electric gripper 16 to push the battery toward the crushing assembly 17. A guide frame is provided between the mounting frame 3 and the crushing assembly 17, allowing the battery to slide into the crushing cylinder 171.

[0035] When the first voltmeter 8 detects that there is still residual power in the battery, it controls the first electric push rod 501 and the front hydraulic cylinder 15 to return to their original positions. The PLC controller then controls the conveyor belt 4 to continue operating. When the conveyor belt 4 transports the battery to the second proximity switch 14, the second proximity switch 14, upon detecting the battery's approach, controls the conveyor belt 4 to stop operating via the PLC controller. Following the aforementioned principle, the battery is clamped, ensuring that both the utilizing posts 11 and the two sensing posts 12 are in contact with the positive and negative terminals of the battery. The utilizing posts 11 and the dust collection pump 21 are electrically connected via the PLC controller and voltage regulator. When the two utilizing posts 11 are in contact with the positive and negative terminals of the battery, the dust collection pump 21 will... Dust pump 21 provides power to start working and collect the dust generated by battery crushing. When the battery power is depleted, the PLC controller controls the dust pump 21 to be electrically connected to the external power supply so that the dust pump 21 continues to work. The PLC controller also controls the second electric push rod 502 and the utilization plate 10 to move upward to the initial position. Then, following the above principle, the PLC controller controls the hydraulic cylinder 15 and the electric gripper 16 on the rear side to work and push the battery to the crushing component 17 for crushing. Since a power test is required before crushing the lithium battery, only a very small amount of power remains inside the battery. Therefore, there is no phenomenon of batteries accumulating on the surface of the conveyor belt 4.

[0036] When a battery falls into the pulverizing cylinder 171, it increases the weight of the cylinder. The cylinder 171 then moves the lifting block 25 downwards via the trigger frame 241. The lifting block 25 moves the sensing block 26 downwards as well, electrically connecting the sensing block 26 to the junction plate 28 and the external power supply. The junction plate 28 is electrically connected to the pulverizing motor 18. When the sensing block 26 contacts the junction plate 28, the circuit of the pulverizing motor 18 is activated, causing the pulverizing motor 18 to operate. The pulverizing motor 18 drives the pulverizer via a gear assembly. The shaft 172 rotates, and the battery is crushed by the crushing shaft 172. After the battery inside the crushing cylinder 171 is crushed, the weight of the crushing cylinder 171 will decrease. Under the action of the spring, the lifting block 25 will drive the sensing block 26 to move upward and contact the sensing plate 27. The sensing plate 27 is electrically connected to the PLC controller. When the sensing block 26 and the sensing plate 27 contact, an electrical signal will be sent to the PLC controller. The PLC controller will then control the front and rear hydraulic cylinders 15 to work, pushing a battery into the crushing cylinder 171 to continue the crushing process.

[0037] The shredded battery fragments fall through the guide pipe 19 into the recycling bin 291 for storage. The recycling bin 291 is filled with water. The less dense fragments, such as plastics, float on the surface, while the denser fragments, such as metals, sink to the bottom of the recycling bin 291. The outer wall of the recycling bin 291 is equipped with a vibrating motor, and the bottom of the recycling bin 291 has a bucket-shaped structure that allows the denser fragments to be transported through the vertical pipe 30 to the horizontal box 292 for storage. This achieves the sorting and processing of the battery fragments. When it is necessary to remove the fragments, the operator can send a signal to the PLC controller via an external button. First, the PLC controller sends an electrical signal to control the linear motor 32. The linear motor 32 drives the mesh frame 35 forward via the third electric push rod 33, collecting the debris floating on the water surface. When the mesh frame 35 moves to the inner rear wall of the collection cylinder 291, the PLC controller controls the third electric push rod 33 to move upward, causing the mesh frame 35 and the debris inside to move upward together. This allows the linear motor 32 to move the mesh frame 35 out of the collection cylinder 291. Then, the collection frame is placed below the mesh frame 35 and the working motor 34 is started, which drives the mesh frame... 35 rotates at a certain angle, causing the debris inside the mesh frame 35 to fall into the collection box. Then, the PLC controller controls the solenoid valve 31 to close, and then controls the drive motor 37 to work. The drive motor 37 drives the threaded cylinder 36 to rotate through the gear assembly, and drives the threaded rod 38 to move through the threaded engagement. The threaded rod 38 pushes the denser debris and water to move backward together through the pusher plate 39, increasing the water pressure behind the pusher plate 39. Under the action of water pressure, some of the liquid will flow back into the recovery cylinder 291 through the return pipe 42 and the one-way valve. When the pusher plate 39 moves to two-thirds of its stroke inside the horizontal box 292, P The LC controller stops the drive motor 37 and controls the air pump 44 to work for one minute. The air pump 44 delivers external gas into the horizontal box 292, which further increases the pressure of the remaining liquid water. Under the pressure, the remaining water will all flow back into the recovery cylinder 291. After the air pump 44 finishes working, the PLC controller controls the fourth electric push rod 40 and the drive motor 37 to work. The fourth electric push rod 40 drives the sealing baffle 41 to move, opening the horizontal box 292 and cleaning out the denser fragments inside the horizontal box 292. This eliminates the need for operators to classify the crushed raw materials afterward, improving the convenience of the operator's work.
