Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling technology, specifically to a sound-insulating and noise-reducing lithium battery shredder. Background Technology

[0002] Lithium battery shredding and recycling is a process of recovering valuable metals such as cobalt, lithium, and nickel from waste lithium batteries through physical crushing and sorting. Due to its structural characteristics, the double-roll crusher is often used in the lithium battery shredding stage. It crushes the battery material to the required particle size through two relatively rotating rollers, which facilitates subsequent sorting and processing.

[0003] Because the internal blade assembly of the existing crusher is made of metal, when feeding lithium batteries to be crushed, the collision of the batteries into the crusher in batches can easily generate a lot of noise. In addition, feeding too many batteries at once increases the pressure on the crusher blade assembly, which can easily cause blockage and is not conducive to the efficiency of battery shredding. To address these issues, a sound-insulating and noise-reducing lithium battery shredder is proposed. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions: A sound-insulating and noise-reducing lithium battery shredder includes a roller crusher, and a feeding mechanism is provided above the roller crusher; The feeding mechanism includes an upper support frame. An upper support rod is fixedly connected to the upper inner side of the upper support frame. A lower support rod is fixedly connected to the lower inner side of the upper support frame away from the upper support rod. The lower support rod and the upper support rod together support and are fixedly connected to a support net on their outer sides. Lifting grooves are respectively opened in the middle of both sides of the upper support frame. Each lifting groove extends in a vertical direction. A support plate is slidably connected to the middle inner side of the upper support frame. Lifting rods are fixedly connected to both ends of the support plate. Each lifting rod is slidably connected along the inner side of the lifting groove. The support plate is located between the lower support rod and the upper support rod, and the support plate is located below the support net.

[0005] As a further embodiment of this utility model: an electric telescopic rod is fixedly installed on the outer wall of the upper support and above one of the lifting slots.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-4 As shown, a sound-insulating and noise-reducing lithium battery shredder includes a roller crusher 1, with a feeding mechanism 2 above the roller crusher 1. The feeding mechanism 2 includes an upper support 201, with an upper support rod 202 fixedly connected to the upper inner side of the upper support 201, and a lower support rod 203 fixedly connected to the lower inner side of the upper support 201 away from the upper support rod 202. The lower support rod 203 and the outer sides of the upper support rod 202 jointly support and are fixedly connected to a support net 204. Lifting grooves 205 are respectively opened in the middle of both sides of the upper support 201, and each lifting groove 205 extends vertically. A support plate 206 is slidably connected to the middle of the inner side of the upper support 201, and lifting rods 207 are fixedly connected to both ends of the support plate 206. Each lifting rod 207 is slidably connected along the inner side of the lifting groove 205. The support plate 206 is located between the lower support rod 203 and the upper support rod 202, and the support plate 206 is located below the support net 204. Figures 1-4 As shown, the upper support rod 202 is positioned above the lower support rod 203. Therefore, when the middle of the support net 204 bulges upward, the material above the support net 204 will first fall out towards the lower support rod 203.

[0018] An electric telescopic rod 209 is fixedly installed on the outer wall of the upper bracket 201 above one of the lifting slots 205. The extension end of the electric telescopic rod 209 is set downward. One end of each lifting rod 207 extends out of the lifting slot 205, and the top of one lifting rod 207 is connected to the flange of the extension end of the electric telescopic rod 209. A handle 208 is fixedly connected to the top of the other lifting rod 207. Figure 2 As shown, the electric telescopic rod 209 can be an HB-DJ series electric actuator with a built-in limit switch to support wireless control.

[0019] A standing platform 210 is fixedly installed on the lower back of the upper support 201, and a ladder 211 is fixedly installed on the back of the standing platform 210. Figures 1-2 As shown, the operator is above the standing platform 210, which facilitates the placement of the lithium battery above the support net 204.

[0020] The roller crusher 1 includes a crushing box 101, with a hopper 102 fixedly connected to the bottom of the crushing box 101. Two reduction motors 103 are fixedly installed on both ends of one side of the crushing box 101. Each reduction motor 103 has its output shaft fixedly connected to a blade assembly 104. Both ends of the blade assembly 104 are rotatably connected to the inner wall of the crushing box 101. Several mounting plates 105 are fixedly connected to the outer wall of the blade assembly 104. Each mounting plate 105 has a through hole 106 in the center of its surface. Figure 1 As shown, the geared motor 103 can be a RH-500N / 700N series model, with high output torque, compact structure, and compatibility with servo motors, suitable for dual-roll crushing scenarios that require precise control.

[0021] Each mounting plate 105 is fitted with a wear-resistant rubber liner 107 on its outer side. Bolts 108 are inserted through the surface of the wear-resistant rubber liner 107, with the middle of the bolt 108 connected to a through hole 106, and the end of the bolt 108 is threaded with a nut 109. Figure 4 As shown, the wear-resistant rubber liner 107 isolates a local area of ​​the blade assembly 104, thereby preventing direct impact on the metal blade assembly when the lithium battery is being fed, and reducing noise generation.

[0022] The top surface of the crushing box 101 is supported and fixedly connected to one side of the bottom of the upper bracket 201. Two blade sets 104 are located on both sides of the lower support rod 203. Guide blocks 110 are fixedly installed on the inner wall of the crushing box 101 on both sides of each blade set 104. A buffer pad is adhered and fixed to the top surface of each guide block 110. Figures 1-2 As shown, the guide block 110 prevents the battery and its fragments from falling off the outside of the blade assembly 104, and the buffer pad can be made of rubber.

[0023] Both the crushing box 101 and the standing platform 210 have fixed support legs at the bottom, and the bottom of each support leg extends to the bottom of the discharge port of the hopper 102.

[0024] The working principle of this utility model: When the device is in use, the operator can move to the top of the standing platform 210 via the ladder 211, and then use tools such as shovels to scoop up the lithium batteries in the transport vehicle and put them into the support net 204. After starting the roller crusher 1, the reduction motor 103 drives the two blade groups to rotate inward. When feeding is required, the operator can control the extension end of the electric telescopic rod 209 to retract via remote control, and drive the pallet 206 to rise vertically along the lifting groove 205. The pallet 206 supports and pushes the middle of the bottom of the support net 204, so that the middle of the support net 204 bulges upward. The batteries above the support net 204 fall gradually down the side of the bulge towards the support rod 203. During this period, the operator can control the extension end of the electric telescopic rod 209 to lift up in stages, so that the lithium batteries above the support net 204 fall into the roller crusher 1 in batches to be crushed. The crushed batteries are discharged through the discharge hopper 102 under the action of gravity.

[0025] When the tool assembly 104 needs to be inspected, the operator can loosen and remove each nut 109, and then pull the bolt 108 out of the wear-resistant rubber liner 107. The wear-resistant rubber liner 107 can then be separated from the mounting plate 105 for disassembly, which is convenient for subsequent replacement.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
