Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery recycling, in particular to a waste battery shell secondary crushing device. Background Art

[0002] With the development of economy and technology, fuel resources are becoming scarce, and new energy sources are needed. Lithium batteries are born as a new energy source. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. With the development of the times, the use of lithium batteries has become more and more extensive, allowing enterprises and factories to produce them on a large scale. However, the service life of lithium batteries is also limited. They will be scrapped after a certain period of use. How to deal with these scrapped lithium batteries has become a problem that we are always concerned about. Although scrapped lithium batteries can no longer be used, they still contain many recyclable accessories. For example, the shell manufacturing materials of lithium batteries are mainly divided into aluminum shells, steel shells and soft shells. In order to effectively extract usable accessories from scrapped batteries, it is necessary to disassemble and screen the waste lithium batteries first. When processing the waste batteries, the shell of the battery will be separated from the harmful chemicals inside. For example, a waste lithium battery shell crushing and screening device (CN218638176U) currently disclosed can separate and recycle the plastic shell and the metal terminal, thereby achieving the purpose of saving resources.

[0003] At present, most battery recycling requires battery disassembly and screening first, with the purpose of disassembling and separating the outer shell, metal core and internal black powder (battery cell) for subsequent processing. There are many devices on the market that can be used for disassembly, which can break up the whole battery one by one, and play a significant role in the recycling of lithium batteries to a large extent. Take one of the impact crushers as an example. As the preliminary work of the lithium battery recycling process, the work of disassembling the lithium battery can separate the battery shell and the battery cell, but it fails to distinguish the shell from the cell well. The battery shell and the battery cell will be transmitted together until they reach the next crushing. In this way, the second crushing will still be together with the outer shell and the battery cell, which will affect the efficiency of the second crushing to a certain extent, and is not conducive to the subsequent processing of battery materials.

The following is a description of the embodiments of the present invention based on its overall structure.

[0025] like Figures 1 to 3As shown, the utility model provides a waste battery shell secondary crushing device, including a first crusher 1, a second crusher 2, a support frame 14, and a conveying mechanism 3; the support frame 14 is placed on the ground, and the conveying mechanism 3 is arranged on the support frame 14, the first crusher 1 is placed on the ground and is located on the side of the support frame 14, the second crusher 2 is placed on the ground and is located at one end of the support frame 14, the first crusher 1 is provided with a first discharge port 9, and the first discharge port 9 is located above the conveying mechanism 3, one end of the conveying mechanism 3 corresponds to the feed port of the second crusher 2, the conveying mechanism 3 is provided with a leakage hole 15, and the side wall of the support frame 14 is provided with a shock material assembly. In this embodiment, the first crusher 1 and the second crusher 2 are both crushers in the prior art. The first crusher 1 is a common impact crusher on the market. Its function is to perform the first crushing on the battery shell to disassemble and separate the battery shell from the battery cell. The disassembled materials flow out from the first discharge port 9 and fall onto the conveying mechanism 3. The disassembled battery shell and battery cell fall on the conveying mechanism 3. These mixed materials fail to achieve the purpose of subsequent processing and will affect the efficiency of the second crushing. In order to improve the efficiency of the second crushing, a conveying mechanism 3 is provided between the first crusher 1 and the second crusher 2. The mixed materials coming out of the first crusher 1 are transported to the feed port of the second crusher 2 through the conveying mechanism 3. The first crushing is mainly for the battery shell and the battery cell. After disassembly and separation, some battery cells and metal particles fall from the leakage hole 15 into the battery cell collecting tank 17 below the conveying mechanism 3 (there will also be a little battery shell debris mixed in, which can be ignored), and are separated from the battery shell. The battery shell that is not completely crushed and some battery cells and metal particles are transported by the conveying mechanism 3 to the feed port of the second crusher 2 for secondary crushing. The second crusher 2 adopts an efficient fine crusher to crush the battery shell into fine particles for subsequent processing. Since there is a conveying mechanism 3 between the first crusher 1 and the second crusher 2, the leakage hole 15 on the conveying mechanism 3 can screen out the separated battery cells, which plays a certain degree of auxiliary role in the crushing efficiency of the second crusher 2, and can reduce the influence of the battery cells on the crushing efficiency.

[0026] The conveying mechanism 3 is provided with a belt 12, and the belt 12 is an elastic belt 12, and the leakage hole 15 is opened on the belt 12, and the leakage hole 15 is provided in plurality and arranged at intervals, and the belt 12 is fixedly connected with a plurality of baffles 8, and the plurality of baffles 8 are arranged at intervals along the running direction of the conveying mechanism 3, and the plurality of baffles 8 are provided with leakage holes 15. In this embodiment, when the material is transported to the feed port of the second pulverizer 2, the material needs to be lifted, and the baffle 8 can be provided to help lift the material to a high place, so that it is not easy to fall from the belt 12, and the baffle 8 is also provided with leakage holes 15, which is more convenient for screening the battery cells and metal particles, so that it is not easy to get blocked during the transportation and screening process.

[0027] The material vibration assembly includes a support plate 4, a vibration cylinder 5, a support block 13, a sliding plate 6, and a top plate 7. The support plate 4 is fixedly mounted on the side wall of the support frame 14, the support block 13 is fixedly mounted on the side wall of the support plate 4, the vibration cylinder 5 is fixedly mounted on the support block 13, the sliding plate 6 is slidably mounted on the support plate 4 and is fixedly connected to the output end of the vibration cylinder 5, the sliding plate 6 extends to the other side of the belt 12, and the top plate 7 is fixedly mounted on the sliding plate 6. In this embodiment, the belt 12 is wrapped into a closed ring with an extendable space in the middle, and the sliding plate 6 and the top plate 7 extend between the folded belt 12. When the equipment is running, the vibration cylinder 5 is started, and its output end moves up and down, so that the top plate 7 moves up and down and continuously indirectly contacts the upper half of the belt 12, so that the belt 12 vibrates, which is more conducive to screening the material, and the sliding plate 6 and the top plate 7 are both inclined, and the inclination is consistent with the inclination angle of the belt 12.

[0028] A transport mechanism 11 is provided below the conveying mechanism 3, a shell collecting trough 16 and a battery collecting trough 17 are provided in the area of ​​the transport mechanism 11, a second discharge port 10 is provided on the second crusher 2, the second discharge port 10 is located above the shell collecting trough 16, and the battery collecting trough 17 is provided below the first discharge port 9. In this embodiment, the shell collecting trough 16 is mainly used to collect battery shells, and the battery cells and metal particles screened out by the first crushing will fall into the battery collecting trough 17 on the transport mechanism 11, and both the shell collecting trough 16 and the battery collecting trough 17 are transported to the next process (not shown in the figure) through the transport mechanism 11.

[0029] The conveying mechanism 3 is provided with an inclined portion 302 and a horizontal portion 301, and the first discharge port 9 is located directly above the horizontal portion 301. In this embodiment, the material crushed by the first crusher 1 falls onto the horizontal portion 301, which is more conducive to the collection of the material and the material is not easy to fall.

[0030] The sliding plate 6 and the top plate 7 are both inclined, and the inclination is consistent with the inclination angle of the belt. In this embodiment, the sliding plate 6 and the top plate 7 are both inclined, so that the sliding plate 6 and the top plate 7 can fit the inner side of the belt 12, so that the vibration effect is better.

[0031] The use method of the utility model: The use of the utility model is mostly based on the existing technology, and some structures are added to improve the work efficiency. Before use, it should be checked whether the equipment is operating normally. The transfer mechanism 3, the shock material assembly, and the transmission mechanism must be operated in advance. The lithium battery is first disintegrated by the first crusher 1 to release the black powder (battery cell). The first crusher 1 (impact crusher) shreds and separates all the battery components of a whole lithium battery. Part of the battery shell is shredded inside the first crusher 1, but the degree of shredding required for subsequent work is not reached. In order to improve the crushing efficiency of the battery, a second crusher 2 is added on the original basis, and a conveying mechanism 3 is provided between the first crusher 1 and the second crusher 2. The shredded shell in the first crusher 1 is conveyed by the conveying mechanism 3. The conveying mechanism 3 is provided with a leakage hole 15. The leakage hole 15 is used to screen the separated battery cells to reduce the influence of the battery cells on the crushing efficiency of the second crusher 2. These shredded battery shells and separated battery cells, as well as the separated metal particles, The battery is sent out from the first discharge port 9 to the belt 12 on the conveying mechanism 3. A part of it falls down under the action of the vibration component in the conveying mechanism 3 and falls into the battery cell collection tank 17. The vibration component is in operation from the beginning. Under the action of the vibration cylinder 5, the sliding plate 6 and the top plate 7 move up and down continuously and indirectly contact the upper part of the belt 12, and make the belt 12 vibrate, which can cooperate with the leakage hole 15 to shake some smaller broken shell pieces and separated battery cells, as well as the separated metal chips, and drop them into the battery cell collection tank below. The shells are mixed with some unseparated battery cells and metal particles and come out from the second discharge port 10 together and fall into the shell collection slot 16 in the transportation mechanism 11 below, and the second crushing is completed. Regardless of whether the material falls into the shell collection slot 16 or the material falls into the battery cell collection slot 17, it will be transferred to the next process for screening again, thus completing the final screening work.
