Description
Technical Field
[0001] The utility model relates to the technical field of battery recycling, and in particular to a complete set of equipment for crushing battery modules. Background Art
[0002] With the significant increase in the number of retired batteries from the new energy vehicle industry, the recycling of used batteries has gained attention. Retired new energy vehicle battery packs are first disassembled into battery modules, which are then broken down into cells. These cells are then crushed and screened to extract the cathode material powder, providing an effective foundation for subsequent recycling.
[0003] The cells of a battery module are usually bonded together by glue or hot melt adhesive to ensure that the cells in the battery module are tightly bonded, avoiding problems such as battery loosening, leakage, and short circuit, so as to improve the safety of the power battery during use. However, this means that violent disassembly must be used to separate each cell during recycling.
[0004] It can be seen from this that if you choose not to disassemble the battery cells but only to disassemble the battery modules, you can save disassembly costs by shortening the disassembly process, avoid the high labor costs caused by battery cell separation, save the space required for the disassembly production line, and avoid battery fires and personnel safety issues caused by violent disassembly.
[0005] The related art provides a method for crushing lithium batteries and lithium battery modules. The device used in this method includes a feed box, a crushing box, a discharge hopper, and a feeding mechanism. The problem is that the weight of a typical battery module is between 40kg and 90kg, and the length is between 600mm and 1800mm. This makes it easy for the battery module to get stuck during the loading process if the feeding method is unreasonable. When the battery module enters the crusher, due to its own weight, it will cause a significant impact on the crushing bearings and blades after falling, which is dangerous and reduces the service life of the equipment.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0035] like Figures 1 to 4 As shown, the present application provides a complete battery module crushing equipment set. An embodiment of the battery module crushing equipment set includes: a crane 10, a loading device 20, and a first crushing device 30. The loading device 20 is suspended from the crane 10. The first crushing device 30 includes a first crushing body 31, a buffer bin 32 connected above the first crushing body 31, and a lower bin 33 connected below the first crushing body 31. The buffer bin 32 is provided with a loading port 321 connected to the loading device 20 and a first discharge port connected to the first upper inlet of the first crushing body 31. A first gate valve 34 is connected between the buffer bin 32 and the first discharge port. The lower bin 33 is connected to the first lower outlet of the first crushing body 31, and a second gate valve 35 is connected between the lower bin 33 and the first lower outlet of the first crushing body 31. The buffer bin 32 has a guide plate 322 arranged in an inclined direction from bottom to top, and the guide plate 322 is located below the loading device 20.
[0036] Applying the technical solution of this embodiment, when the crane 10 is working, it lifts the loading device 20 and lifts it to the buffer bin 32. The staff transports the battery module 101 on the loading device 20 to the buffer bin 32. Since the guide plate 322 is tilted from bottom to top, it is convenient for the battery module 101 to slide from bottom to top along the guide plate 322 to the top of the first crushing body 31. When the first gate valve 34 opens the loading port 321, the battery module 101 can enter the first crushing body 31, and the first crushing body 31 can crush the battery module 101. When the second gate valve 35 opens the first lower outlet, the crushed material of the battery module 101 in the first crushing body 31 can be collected in the lower bin 33. This application uses the crane 10 and the guide plate 322 to cooperate to allow the battery module 101 to slide into the first crushing body 31. This can reduce the possibility of the battery module 101 getting stuck during the loading process. Therefore, the technical solution of this embodiment solves the problem in the related art that the battery module is easily stuck during the loading process.
[0037] In addition, during the process of conveying the battery module 101 to the buffer bin 32, the above-mentioned first gate valve 34 closes the feeding port 321, and the first gate valve 34 isolates the buffer bin 32 and the first crushing body 31, preventing the battery module 101 from being too heavy and falling directly into the first crushing body 31, avoiding impact on the first crushing cutter shaft of the first crushing body 31, and reducing the failure rate of the battery module crushing equipment.
[0038] The battery module crushing equipment provided in this application has good stability, low equipment failure rate, simple operation, and good discharge effect.
[0039] In this embodiment, the buffer chamber 32 is preferably tilted at a 40-degree angle from bottom to top. A water sprinkler fire extinguishing port is provided at the top of the buffer chamber 32. This port is conveniently connected to an external water sprinkler pipe. This water spray can further extinguish any fire that may occur in the first crushing body 31, further enhancing the safety of the battery module crushing equipment.
[0040] like Figures 1 to 4 As shown, the loading device 20 includes a loading rack 21 suspended from the crane 10 and a plurality of rollers 22 rotatably mounted on the loading rack 21. The plurality of rollers 22 are spaced apart along the loading direction of the loading rack 21. The arrangement of the rollers not only ensures smooth movement of battery modules, such as lithium-ion battery modules, during loading, but also prevents degradation or damage to the battery due to excessive vibration.
[0041] like Figures 1 to 4As shown, the plane where the loading port 321 is located is tilted upward relative to the loading direction. The tilted design of the loading port utilizes gravity to assist in the introduction of the battery module 101, which not only reduces power consumption but also improves the smoothness of the introduction of the crushed battery module 101. It is suitable for processing battery modules of various shapes and sizes, such as square, cylindrical, or irregular shapes, making the equipment more adaptable to the crushed battery module 101.
[0042] like Figures 1 to 4 As shown, a third gate valve 36 is installed at the feed port 321, and a nitrogen inlet and an air extraction port are provided on the buffer chamber 32. The third gate valve 36 controls the amount of battery modules 101 entering, preventing overloading or reduced efficiency of the crushing process caused by excessive battery modules being added at once. The nitrogen inlet also facilitates the introduction of nitrogen from outside the battery module crushing equipment into the buffer chamber 32. When the first gate valve 34 opens the feed port 321, nitrogen within the buffer chamber 32 can enter the first crushing body 31. When the third gate valve 36 closes the feed port 321 and the second gate valve 35 closes the first lower outlet, the interiors of the buffer chamber 32 and the first crushing body 31 remain sealed. The air extraction port allows some nitrogen in the buffer chamber 32 to be extracted, maintaining a slightly positive pressure. When the oxygen concentration in the buffer chamber 32 and the first crushing body 31 is less than 4%, the first crushing body 31 begins crushing the battery modules 101. The inert gas protection provided within the buffer chamber 32 and the first crushing body 31 effectively prevents accidental combustion or explosion of the battery modules due to the introduction of external oxygen during the crushing process, significantly improving the safety of the equipment. The aforementioned third gate valve 36, second gate valve 35, nitrogen port, and exhaust port enhance the sealing and oxygen control capabilities of the battery module crushing equipment, eliminating the risk of shattering charged battery modules.
[0043] like Figures 1 to 4 As shown, the battery module crushing equipment also includes a conveyor belt 41 arranged between the loading device 20 and the first crushing device 30. The setting of the conveyor belt realizes the continuous operation of the battery module from loading to crushing, improves the automation level and processing efficiency of the equipment, and is suitable for the crushing processing of large-scale battery modules. The battery module crushing equipment also includes a discharge device 42 arranged upstream of the loading device 20. The front design of the discharge device can safely discharge the battery module before it enters the crushing, avoids accidents caused by residual battery energy during the crushing process, and improves the stability and safety of the equipment. The conveyor belt is preferably a plate chain conveyor belt. The discharge device 42 is preferably an inverter feedback discharge device, which discharges the single cell in the battery module to below 1.6V to reduce the subsequent heat generation of the battery module crushing and increase the subsequent crushing processing capacity. The inverter feedback discharge device is an inverter feedback discharge cabinet, which is used to discharge the battery pack / battery module.
[0044] like Figures 1 to 6 As shown, the battery module crushing equipment also includes a second crushing device 50 disposed downstream of the first crushing device 30. The introduction of the second crushing device allows the battery module to be further crushed after the first stage of coarse crushing by the first crushing body 31. This is suitable for scenarios with high requirements for crushing particle size, such as the fine recycling of battery materials. It ensures that the crushed materials of the battery module 101 can meet the requirements of subsequent processing or recycling, thereby improving the recycling rate of resources.
[0045] In other embodiments, the second crushing device 50 is stacked with the first crushing device 30, which saves space and equipment and helps reduce costs.
[0046] like Figures 1 to 6 As shown, the second crushing device 50 includes a second crushing body 51 and a turning mechanism 52 disposed upstream of the second crushing body 51. The second upper inlet 513 of the second crushing body 51 is connected to the turning mechanism 52. The turning mechanism can lift and turn the crushed material of the battery module 101, ensuring that the crushed material of the battery module 101 can smoothly enter the second crushing body 51 through the second upper inlet 513, thereby improving the crushing efficiency and the stability of the crushing quality.
[0047] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the turning mechanism 52 comprises a lifting mechanism 521, a turning box 522 reversibly mounted on the lifting mechanism 521, and a guide structure disposed between the second crushing body 51 and the turning box 522. The guide structure comprises a guide groove 53 bent toward the second upper inlet 513 and a guide shaft 54 that cooperates with the guide groove 53. One of the guide groove 53 and the guide shaft 54 is disposed on the second crushing body 51, and the other is disposed on the turning box 522. The crushed material of the battery modules 101 can be loaded into the turning box 522. The lifting mechanism transports the crushed material of the battery modules 101 during lifting. The guide groove 53 and the guide shaft 54 of the guide structure precisely guide the movement of the turning box 522, facilitating the turning of the turning box 522 and pouring the crushed material of the battery modules 101 within the turning box 522 into the second crushing body 51. This design significantly increases the processing speed of the crushed material of the battery modules 101, reduces energy consumption, and improves overall recycling capacity. The lifting mechanism 521 is preferably a belt drive mechanism.
[0048] In this embodiment, the tilting box 522 includes a tilting seat 5221 and a temporary storage box 5222 detachably mounted on the tilting seat 5221. The tilting seat 5221 is provided with a swingable crossbeam, which has a clamping position for clamping the temporary storage box 5222 to the tilting seat 5221 and a release position for releasing the temporary storage box 5222 from the tilting seat 5221. When the crossbeam is in the clamping position, the temporary storage box 5222 is fixed to the tilting seat 5221 and moves as the tilting seat 5221 is lifted by the lifting mechanism 521. When the crossbeam is in the release position, the temporary storage box 5222 can be removed from the tilting seat 5221 by a forklift.
[0049] like Figures 1 to 6 As shown, the first crushing unit 31 includes a first housing 311 connected between the buffer bin 32 and the discharge bin 33, and multiple first crushing shafts 312 disposed within the first housing 311. The multiple first crushing shafts 312 are rotatably arranged at intervals. The multiple first crushing shafts 312 enable efficient and rapid crushing of the battery modules 101, facilitating the rough processing of hard or high-density battery modules, such as those used in electric vehicles. This ensures effective crushing while reducing the difficulty of subsequent processing. The second crushing unit 51 includes a second housing 511 and a second crushing shaft 512 rotatably disposed within the second housing 511. The second crushing shaft 512 further crushes the crushed material from the battery modules 101, achieving fine processing of hard or high-density battery modules, ensuring that the crushed material from the battery modules 101 meets the requirements for subsequent processing or recycling. Four first crushing shafts 312 are preferably used. The simultaneous use of multiple first crushing shafts 312 ensures stable crushing, reduces equipment failure rates, and achieves high crushing yields and excellent crushing results.
[0050] In this embodiment, the first crushing body 31 further includes a cooling chamber 313 connected between the first housing 311 and the discharge bin 33. A water-cooling circulation pipe is provided on the inner wall of the cooling chamber 313. The cooling chamber 313 cools the crushed battery modules 101 that fall from the first housing 311. When the second gate valve 35 reopens the first lower outlet, the cooled crushed battery modules 101 fall from the cooling chamber 313 into the discharge bin 33.
[0051] In this embodiment, the top opening of the first shell 311 is the first upper inlet of the first crushing body 31 , and the bottom opening of the cooling chamber 313 is the first lower outlet of the first crushing body 31 .
[0052] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the battery module crushing equipment also includes a storage box 60 arranged downstream of the second crushing device 50, and the second lower outlet of the second crushing body 51 is connected to the storage box 60. The provision of the storage box 60 can collect and store the crushed materials of the battery module 101 in a timely manner, and is suitable for scenarios where the crushed materials of the crushed battery module 101 need to be stored or transported, thereby improving the continuity and convenience of the processing of the crushed materials of the battery module 101. In actual applications, the design of the storage box takes into account the classified storage of the crushed materials of the battery module 101, which facilitates the subsequent sorting and reprocessing of battery materials and improves the efficiency and economic benefits of resource recovery.
[0053] In this embodiment, the battery module is first shredded by four first shredder shafts 312, shredding it into fragments measuring 40 mm (±10 mm) in length and width. These four first shredder shafts 312 offer rapid shredding, reducing the risk of battery short-circuit heating and combustion. The shredded material is then finely shredded by a single second shredder shaft 512, shredding it into fragments measuring 20 mm (±10 mm) in length and width. This results in a loose and uniform material, facilitating subsequent screening and powdering.
[0054] The battery module crushing equipment obtained in this application reduces the fire risk of crushing through battery pack / battery module discharge equipment, designs multiple buffers and cooling chambers, and introduces nitrogen to further reduce the risk during the battery module crushing process; uses a combination of four-axis and single-axis crushers for crushing, and fully considers the size, weight, and material of the battery modules in the design, ultimately achieving the purpose of crushing battery modules in batches.
[0055] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0057] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.
[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
