Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling, and in particular to a device and process for recycling rare metals from retired power batteries. Background Art

[0002] Retired new energy vehicle power batteries refer to lithium-ion battery systems that are removed from new energy vehicles and enter the recycling stage when their capacity has decayed to 70% to 80% of the initial value (or cannot meet the vehicle design performance requirements), their safety has decreased, or their economy is insufficient. When recycling retired new energy vehicle power batteries, it is necessary to separate the battery casing, then remove the internal battery, and extract rare metals such as nickel, cobalt, manganese, and lithium from the battery.

[0003] In the prior art, when disassembling and separating the outer shell of a power battery, the shell cover and both sides of the shell are generally clamped directly, and then the shell cover and the shell are separated. Since there are two protrusions on the top of the shell cover, the top of the shell cover is in an irregular state. Therefore, when the shell cover is clamped, it will slip, resulting in the inability to complete the separation operation of the battery shell, thereby affecting the subsequent recycling operation. In addition, before separation, it is necessary to use tools to lift the power battery onto the device, resulting in a slow loading speed, thereby affecting the subsequent disassembly and separation operations.

[0033] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0034] like Figures 1-9The rare metal recovery device for retired power batteries shown in the figure includes a bottom plate 1, with support columns 8 fixedly connected at the four corners of the top of the bottom plate 1, and a top plate 6 fixedly connected to the top of the four support columns 8. The bottom plate 1 and the top plate 6 are provided with an adsorption separation mechanism, a spray enhancement mechanism and a lifting and conveying mechanism; the adsorption separation mechanism includes a placement groove 22 opened at the top of the bottom plate 1, and the bottom end of the placement groove 22 is connected to a plurality of uniformly arranged first cone grooves 29, and the inner wall of each first cone groove 29 is fixedly connected to a first suction cup 23, and each first suction cup 23 is used to adsorb and fix the bottom end of the battery body 21, and also includes a lifting seat 1 5. A first groove 27 and a second groove 33 are respectively formed at the bottom of the lifting seat 15. The shapes of the first groove 27 and the second groove 33 are adapted to the raised portion at the top of the battery body 21. A plurality of second conical grooves 36 are formed on the top of the inner walls of the first groove 27 and the second groove 33 and on the bottom of the lifting seat 15. A second suction cup 34 is fixedly connected to the inner wall of each second conical groove 36. Each second suction cup 34 is used to adsorb the top of the battery body 21. The first suction cup 23 partially extends from the placement groove 22, and the second suction cup 34 partially extends from the first groove 27, the second groove 33 and the lifting seat 15.

[0035] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 9 As shown, the adsorption and separation mechanism also includes exhaust fans B18 fixedly connected to both sides of the bottom end of the base plate 1. The two exhaust fans B18 are connected to each first suction cup 23 via a connecting pipe B17. The mechanism also includes exhaust fans A7 fixedly connected to both sides of the top end of the lifting base 15. The two exhaust fans A7 are connected to each second suction cup 34 via a connecting pipe A38. The exhaust fans B18 and A7 can generate negative pressure within the first suction cup 23 and the second suction cup 34, thereby achieving adsorption and preventing the objects from falling off during adsorption.

[0036] like Figure 3 、 Figure 4 As shown, the adsorption and separation mechanism also includes an electric push rod 5 symmetrically fixed and passing through the top plate 6. The telescopic ends of the two electric push rods 5 are fixedly connected to the lifting seat 15. Four guide columns 4 are fixedly connected to the top of the lifting seat 15. The four guide columns 4 all pass through the top plate 6. The outer wall of the lifting seat 15 is fixedly connected to the protective shell 9. The outer side of the corresponding placement groove 22 at the top of the bottom plate 1 is provided with a mouth-shaped groove 20 that matches the shape of the protective shell 9. The lifting seat 15 is moved up and down by the electric push rod 5 to complete the disassembly and separation operation, preventing it from falling off during disassembly and separation. The protective shell 9 and the mouth-shaped groove 20 can provide protection during disassembly and separation, preventing debris generated during disassembly and separation from jumping onto surrounding workers, thereby improving safety.

[0037] like Figure 2 、 Figure 4 、 Figure 5As shown, the spray enhancement mechanism includes three groups of first atomizing nozzles 24 fixedly extending through the first suction cup 23. Each group of first atomizing nozzles 24 is symmetrically arranged, and a first water inlet pipe 28 is fixedly connected between each group of first atomizing nozzles 24. Each first water inlet pipe 28 extends through the base plate 1. The first atomizing nozzles 24 spray water mist into the first suction cup 23 and the top of the battery body 21, thereby enhancing suction.

[0038] like Figure 1 、 Figure 2 、 Figure 9 As shown, the spray enhancement mechanism also includes a second atomizing nozzle 35 fixedly extending through the second suction cup 34. There are three groups of second atomizing nozzles 35, each of which is fixedly connected to a second water inlet pipe 37. Each second water inlet pipe 37 extends through the lifting base 15. The second atomizing nozzle 35 sprays water mist toward the second suction cup 34 and the bottom end of the battery body 21 housing to enhance suction.

[0039] like Figure 2 、 Figure 6 As shown, the lifting and conveying mechanism includes a square slot 30 provided at the bottom of the inner wall of the placement slot 22. There are four square slots 30, each of which is slidably penetrated by a square column 12. The tops of the four square columns 12 are fixedly connected to a placement block 31. The tops of the four placement blocks 31 are symmetrically fixedly connected to side panels 32. Conveyor belts B26 are installed between the four sets of side panels 32. The lifting and conveying mechanism also includes a U-shaped frame 14 fixedly connected to the middle of the bottom end of the base plate 1. The inner wall of the U-shaped frame 14 is fixedly connected to a hydraulic rod 16. The telescopic end of the hydraulic rod 16 is fixedly connected to a square plate 13. The square plate 13 and the four square columns 12 are fixedly connected. The square slots 30 are used to place the side panels 32, the placement blocks 31 and the conveyor belt B26. The four square columns 12 are connected together by the square plate 13 so that they move synchronously.

[0040] like Figure 2 、 Figure 5 As shown, the lifting and conveying mechanism also includes circular grooves 25 symmetrically arranged at both ends of the base plate 1. Circular columns 2 are slidably mounted on the inner walls of both sets of circular grooves 25. A placement plate 3 is fixedly connected to one end of each set of circular columns 2, facing away from each other. Three-stage cylinders 19 are fixedly connected to the inner sides of the corresponding circular grooves 25 at both ends of the base plate 1. The telescopic ends of the two three-stage cylinders 19 are respectively fixedly connected to the two placement plates 3. The cooperation between the circular grooves 25 and the circular columns 2 allows the placement plates 3 to be limited, ensuring stable movement. The three-stage cylinders 19 provide power to complete the operation.

[0041] like Figure 1 、 Figure 2As shown, the tops of the two placement plates 3 are fixedly connected to fixed plates 10, which are higher than the bottom plate 1. Cross plates are fixedly installed on both sides of the tops of the two fixed plates 10. A conveyor belt A11 is installed between each set of cross plates. Conveyor belt A11 and conveyor belt B26 are on the same horizontal line. The height of the fixed plates 10 is higher than the bottom plate 1, which facilitates the inward movement of the fixed plates 10 and brings conveyor belts A11 and B26 closer together, facilitating the conveyance of the battery body 21, thereby improving the efficiency of loading and unloading. Conveyor belts A11 and B26 are both existing technologies and will not be described here.

[0042] The rare metal recovery process for retired power batteries includes the following steps:

[0043] Step 1: First, the battery body 21 is transported to the top of the placement slot 22 by the lifting and conveying mechanism. Then, the battery body 21 is placed into the placement slot 22 to complete the loading operation.

[0044] Step 2: Spraying water mist onto the top and bottom of the battery body 21 and the inside of the first suction cup 23 and the second suction cup 34 through the spray enhancement mechanism to enhance the adsorption effect;

[0045] Step 3: Use the first suction cup 23 and the second suction cup 34 to fix them on the top and bottom ends of the battery body 21 respectively, and then separate the top cover and shell of the battery body 21 through the adsorption separation mechanism to complete the disassembly of the battery body 21, facilitating the subsequent recovery of rare metals.

[0046] Working principle: Before disassembly and separation, the lifting seat 15 is in a position close to the top plate 6. At this time, the hydraulic rod 16 is started to push the square plate 13 upward, and at the same time, the square column 12 and the placement block 31 are pushed upward. Since the limit frame is fixed on the square column 12, the top of the conveyor belt B26 is higher than the top of the bottom plate 1. At the same time, the three-stage cylinders 19 on both sides are started to move the placement plate 3 toward the bottom plate 1, and the placement plate 3 moves with the fixed plate 10. Since the fixed plate 10 is higher than the top of the bottom plate 1, the fixed plate 10 can continue to move inward and make the fixed plate 10 is close to the placement block 31, and the conveyor belt A11 is close to the conveyor belt B26. Since the conveyor belts A11 and B26 are both existing technologies, the battery body 21 can be transported to the top of the placement groove 22. At this time, the fixed plate 10 is reset, and the hydraulic rod 16 is reversely started to move downward with the square plate 13 and the square column 12, and the battery body 21 is placed inside the placement groove 22, and the conveyor belt B26 is separated from the bottom end of the battery body 21. At this time, the bottom end of the battery body 21 contacts the first suction cup 23 and is discharged to the first atomizing nozzle 24 through the first water inlet pipe 28. Water is injected into the first suction cup 23 and the bottom of the battery body 21 through the first atomizing nozzle 24, and then the electric push rod 5 is controlled by the synchronous controller to move synchronously. The electric push rod 5 pushes the lifting seat 15 downward, and when moving downward, water is injected into the second atomizing nozzle 35 through the second water inlet pipe 37. The water is atomized by the second atomizing nozzle 35 and sprayed on the inside of the second suction cup 34 and the top of the battery body 21 shell. Then, the pressure is continued to be pressed down so that the top and bottom of the battery body 21 are in close contact with the first suction cup 23 and the second suction cup 34. At this time, the exhaust fan A7 is started to generate negative pressure in the second suction cup 34 through the connecting pipe A38, so that the top of the battery body 21 can be adsorbed. At the same time, the exhaust fan B18 is started to generate negative pressure in the first suction cup 23 through the connecting pipe B17, so that the bottom of the battery body 21 shell can be adsorbed and fixed. At this time, the electric push rod 5 is started in the reverse direction to move the lifting seat 15 upward, so that the shell of the battery body 21 can be disassembled and separated, avoiding falling off during disassembly and separation, ensuring subsequent separation operations and subsequent recycling operations;

[0047] After the shell of the battery body 21 is disassembled, the exhaust fan B18 and the exhaust fan A7 are turned off, and the negative pressure in the second suction cup 34 and the first suction cup 23 is cancelled. At this time, the shell cover falls on the battery body 21, and the hydraulic rod 16 is started to push the square plate 13 upward, and at the same time push the square column 12 and the placement block 31 upward. Since the limit frame is fixedly installed on the square column 12, the top of the conveyor belt B26 is higher than the top of the bottom plate 1. At the same time, the three-stage cylinders 19 on both sides are started to move the placement plate 3 toward the bottom plate 1, and the placement plate 3 moves with the fixed plate 10. Since the fixed plate 10 is higher than the top of the bottom plate 1, the fixed plate 10 can continue to move inward and make the fixed plate 10 close to the placement block 31, and the conveyor belt A11 is close to the conveyor belt B26, so that the battery body 21 after disassembly and separation can be transported out, so it is convenient and quick to take out.
