[0043] The following will refer to the appendices in this application. Figure 1 To be continued Figure 7 The technical solutions in this application are clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of a battery crushing device 10 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the battery crushing device 10 provided in another embodiment of this application. Figure 3 This is a cross-sectional schematic diagram of the battery crushing device 10 provided in this application embodiment under abnormal feeding conditions. The battery crushing device 10 includes a feeding channel 100, a crushing chamber 200, a crushing mechanism 300, and a pressing mechanism 400.

[0046] The feeding channel 100 is provided with a feed inlet 110. The material to be crushed enters the feeding channel 100 through the feed inlet 110, and the feeding channel 100 is used to receive the material to be crushed. The crushing chamber 200 is connected to the feeding channel 100, and the feeding channel 100 is inclined relative to the crushing chamber 200. The crushing mechanism 300 includes a crushing blade 310, which is disposed in the crushing chamber 200. The crushing mechanism 300 and the crushing blade 310 are used to physically crush the material to be crushed. The pressing mechanism 400 includes a pressing member 410, which is movably disposed in the feeding channel 100 or the crushing chamber 200. The pressing member 410 is movably disposed on the side of the crushing blade 310 near the feeding channel 100. The pressing member 410 can move when the battery crushing device 10 is in an abnormal feeding state, and provides a force close to the crushing blade 310 to the material to be crushed, causing the crushing blade 310 to crush the material to be crushed.

[0047] It is understood that the feed channel 100 is a pipe structure for conveying materials to be crushed. In some examples, the feed channel 100 is a one-piece pipe structure. In other examples, the feed channel 100 is formed by splicing multiple pipe structures. Sealing design at the joints of multiple pipe structures (including but not limited to sealing the joints of two adjacent pipes with sealing strips) can ensure the airtightness of the spliced ​​feed channel 100. The feed channel 100 can be, but is not limited to, a circular pipe structure, a square pipe structure, or an irregularly shaped structure; this application does not limit the shape of the feed channel 100.

[0048] It is understandable that the crushing chamber 200 is the core working area of ​​the battery crushing device 10. For example... Figures 1 to 3As shown, the battery crushing device 10 also includes a base 600. A crushing chamber 200 is disposed parallel to the base 600, with its cross-section parallel to the surface of the base 600. A feed channel 100 is disposed above the crushing chamber 200. The extension direction of the feed channel 100 (or the axis / centerline of the feed channel 100) forms an angle with the cross-section of the crushing chamber 200, and also with the surface of the base 600, thus allowing the feed channel 100 to communicate obliquely with the crushing chamber 200. The obliquely disposed feed channel 100 allows the material to be crushed to automatically enter the crushing chamber 200 under its own gravity. The crushing blades 310 disposed in the crushing mechanism 300 can crush the material.

[0049] Understandably, in some examples, the angle of inclination between the feed channel 100 and the crushing chamber 200 is between 45 and 55 degrees (inclusive), which is the angle between the extending direction of the feed channel 100 (or the axis / centerline of the feed channel 100) and the cross-section of the crushing chamber 200. In other examples, the angle of inclination between the feed channel 100 and the crushing chamber 200 is between 45 and 50 degrees (inclusive). For example, the angle of inclination between the feed channel 100 and the crushing chamber 200 is 45, 47, 50, 52, or 55 degrees. The aforementioned angles of inclination of the feed channel 100 allow the material to be crushed to slide into the crushing chamber 200 at a suitable speed. The speed of the material to be crushed is not too slow, which would make it difficult for the material to slide into the crushing chamber 200 and reduce the working efficiency of the battery crushing device 10. The speed of the material to be crushed is also not too fast, which would cause a violent collision with the crushing blade 310, resulting in sparks and safety issues. Meanwhile, the speed of the material to be crushed will not be too fast, and the material will not easily bounce back after colliding with the crushing blade 310, thus reducing the crushing efficiency. The above-mentioned design of the inclined angle between the feed channel 100 and the crushing chamber 200 in this application can balance the production efficiency and safety of the battery crushing device 10.

[0050] It is understandable that, such as Figure 3 As shown, in some examples, the battery crushing device 10 also includes a discharge channel 500 communicating with the crushing chamber 200, through which the material crushed by the crushing mechanism 300 can be discharged. Furthermore, the feed channel 100, the crushing chamber 200, the crushing mechanism 300, and the discharge channel 500 form a continuous material crushing path. The battery crushing device 10 of this application can achieve automatic and continuous crushing of the material to be crushed, greatly improving the crushing efficiency of the battery crushing device 10.

[0051] It is understandable that the pressing component 410 is located above the crushing cutter 310. When the pressing component 410 is movably disposed in the feed channel 100 or the crushing chamber 200, the pressing component 410 is less likely to introduce air into the crushing chamber 200, thereby reducing the risk of flammability and explosion of the crushing chamber 200.

[0052] It is understandable that the pressing component 410 can move relative to the crushing cutter 310. Specifically, the pressing component 410 assists the crushing cutter 310 in crushing the abnormally fed material when the battery crushing device 10 is in an abnormal feeding state. The abnormal feeding state of the battery crushing device 10 is in contrast to the normal feeding state. Please refer to... Figures 1 to 3 Please refer to Figure 4 , Figure 4 This is a cross-sectional view of the battery crushing device 10 under normal feeding conditions provided in this application embodiment. When the battery crushing device 10 is in normal operating condition, the material to be crushed enters the crushing mechanism 300 along the feed inlet 110, feed channel 100, and crushing chamber 200 and is normally crushed by the crushing mechanism 300.

[0053] In contrast, such as Figure 3 As shown, the material to be crushed enters the crushing mechanism 300 through the feed inlet 110, feed channel 100, and crushing chamber 200. Some abnormal material may bounce away from the crushing blade 310 after colliding with it and cannot be properly crushed. In this case, the discharge channel 500 cannot discharge material normally, or the discharge volume of the discharge channel 500 decreases. By monitoring the discharge volume of the discharge channel 500, it can be determined whether the battery crushing device 10 is in an abnormal feeding state. If the battery crushing device 10 is in an abnormal feeding state, the movable pressing member 410 moves relative to the crushing blade 310 and provides a force close to the crushing blade 310 to the material to be crushed, causing the crushing blade 310 to crush the material.

[0054] In this embodiment of the battery crushing device 10, the feeding channel 100 is inclined relative to the crushing chamber 200. The material to be crushed can enter the crushing chamber 200 along the inclined feeding channel 100 under its own gravity and be crushed by the crushing blades 310 within the crushing chamber 200. The battery crushing device 10 can achieve automatic feeding of the material to be crushed, greatly improving its feeding efficiency. Furthermore, the pressing member 410 is movable, allowing it to move when the battery crushing device 10 is in an abnormal feeding state. The pressing member 410 provides a force close to the crushing blades 310 to the material in the abnormal feeding state, causing the material to be crushed by the crushing blades 310. Compared to related technologies that stop the operation of the battery crushing device 10 for maintenance in an abnormal feeding state, the battery crushing device 10 of this application, under the action of the pressing member 410, is more efficient in solving the problem of abnormal feeding of the material to be crushed. Therefore, the battery crushing device 10 of this application has higher feeding efficiency and abnormal feeding efficiency, resulting in higher working efficiency. Moreover, the pressing component 410 of this application is located inside the feeding channel 100 or the crushing chamber 200. Compared with the reciprocating pushing mechanism located outside the feeding channel in related technologies, the pressing component 410 of this application is less likely to introduce air into the crushing chamber 200, which can reduce the risk of flammability and explosion of the crushing chamber 200. The battery crushing device 10 of this application has better safety performance.

[0055] In some examples, the pressing element 410 is configured to switch between a first position and a second position. When the pressing element 410 is in the first position, it provides a force to the material to be crushed close to the crushing blade 310. When the pressing element 410 is in the second position, it is offset from the crushing blade 310.

[0056] Understandably, in some examples, when the clamping element 410 is in the first position, the clamping element 410 obstructs at least a portion of the crushing tool 310. For example... Figure 3 As shown, under abnormal feeding conditions, the pressing component 410 is in the first position and blocks part or all of the crushing blade 310. In the first position, the pressing component 410 and the orthographic projection of the crushing blade 310 on the cross section of the crushing chamber 200 or the surface of the base 600 coincide or completely coincide, so that the pressing component 410 is located on the path between the material to be crushed and the crushing blade 310. The pressing component 410 can block the rebounding material to be crushed, thereby solving the abnormal feeding problem of the battery crushing device 10.

[0057] Understandably, in some examples, when the battery crushing device 10 is in an abnormal feeding state, the pressing member 410 is used to block at least part of the crushing blade 310 and to move in the direction toward the crushing blade 310. At this time, the pressing member 410 can further press the rebounding material to be crushed toward the crushing mechanism 300, so that the crushing mechanism 300 can re-crush the material to be crushed. Thus, the pressing member 410, which can move toward the crushing blade 310, can further improve the abnormal feeding efficiency of the battery crushing device 10.

[0058] Understandably, in some examples, when the pressure member 410 is in the second position, the extending direction of the pressure member 410 is parallel to the extending direction of the feed channel 100. For example... Figure 4 As shown, when the battery crushing device 10 is in the normal feeding state, the pressing member 410 is in the second position. In the second position, the pressing member 410 is partially or completely offset from the crushing blade 310. The pressing member 410 and the crushing blade 310 in the second position coincide or are completely separated in their orthogonal projections on the cross section of the crushing chamber 200 or the surface of the base 600. At this time, the pressing member 410 is less likely to block the communication path between the feeding channel 100 and the crushing blade 310, and the material to be crushed can be normally crushed by the crushing blade 310, resulting in a high efficiency of normal feeding of the battery crushing device 10.

[0059] Understandably, in some examples, when the battery crushing device 10 is in normal feeding mode, the pressing member 410 is used to move in a direction away from the crushing blade 310 and is offset from the crushing blade 310. At this time, the pressing member 410, after moving in a direction away from the crushing blade 310, is less likely to block the path between the feed channel 100 and the crushing blade 310, which can further improve the normal feeding efficiency of the battery crushing device 10.

[0060] It is understood that the pressing member 410 can move in a direction toward the crushing blade 310 and block the crushing blade 310 in a first position, and can also move in a direction away from the crushing blade 310 and offset from the crushing blade 310 in a second position. The pressing member 410 can switch between the first and second positions. In some examples, the pressing mechanism 400 also includes a drive mechanism (not shown in the figures), which is connected to the pressing member 410 and provides driving force to the pressing member 410 and drives the pressing member 410 to move. In some examples, the drive mechanism can drive the pressing member 410 to switch between the first and second positions. For example, the drive mechanism is used to drive the pressing member 410 to move in a direction toward the crushing blade 310 when the battery crushing device 10 is in an abnormal feeding state. The drive mechanism is also used to drive the pressing member 410 to move in a direction away from the crushing blade 310 when the battery crushing device 10 is in a normal feeding state. In some examples, the drive mechanism may be, but is not limited to, a motor drive structure, a hydraulic drive structure, a pneumatic drive structure, an electromagnetic drive structure, or a manual drive structure.

[0061] Understandably, in some examples, the pressing mechanism 400 also includes a limiting member to restrict the movement range of the pressing member 410, which is used to prevent interference between the pressing member 410 and the crushing tool 310. For example, when the drive mechanism drives the pressing member 410 to move linearly toward the crushing tool 310, the limiting member can be positioned at a certain distance above the crushing tool 310 (e.g., the limiting member is located in an area of ​​about 5 to 20 centimeters above the crushing tool 310), which can prevent the pressing member 410 from continuing to move toward the crushing tool 310. As another example, when the drive mechanism drives the pressing member 410 to rotate toward the crushing tool 310, the limiting member can limit the rotation angle of the pressing member 410, for example, but not limited to, allowing the maximum rotation angle of the pressing member 410 relative to the surface of the base 600 to be about 60 degrees, so as to avoid interference between the pressing member 410 and the crushing tool 310. It should be noted that any limiting component that can prevent interference between the pressing component 410 and the crushing tool 310 is within the scope of protection of this application.

[0062] The battery crushing device 10 of this application, under the combined action of the feeding channel 100, the crushing chamber 200, the crushing mechanism 300, and the pressing component 410, can switch between a first position and a second position. The battery crushing device 10 can achieve automatic and continuous feeding of the material to be crushed in both normal and abnormal feeding states, greatly improving the working efficiency of the battery crushing device 10 under different conditions. Furthermore, when the pressing component 410 is in the first position and blocks at least part of the crushing blade 310, it can block the rebounding material that has not been crushed by the crushing blade 310. The pressing component 410 can better provide a force close to the crushing blade 310 for the material to be crushed, thus improving the reliability of the battery crushing device 10 in solving abnormal feeding problems. When the pressing component 410 is in the second position and is offset from the crushing blade 310, it is less likely to block the path between the feeding channel 100 and the crushing blade 310, making normal feeding of the battery crushing device 10 smoother.

[0063] It should be noted that in some examples, the pressure member 410 of this application embodiment can also move to other positions, such as a position between the first position and the second position. This application embodiment does not limit the movement mode of the pressure member 410.

[0064] Please refer to this again. Figure 3 and Figure 4 In some examples, the pressing element 410 is a rotating pressing element. The pressing element 410 is rotatably connected to the wall of the crushing chamber 200, or the pressing element 410 is rotatably connected to the wall of the feed channel 100. The pressing element 410 can rotate in a direction toward the crushing cutter 310 or in a direction away from the crushing cutter 310.

[0065] It is understandable that the drive mechanism of the pressing mechanism 400 is rotatably connected to the pressing component 410, and the pressing component 410 rotates under the drive of the rotating shaft of the drive mechanism. For example... Figure 3 As shown, when the battery crushing device 10 is in an abnormal feeding state, the pressing member 410, driven by the drive mechanism, rotates in the direction toward the crushing blade 310 to block the crushing blade 310. For example, the pressing member 410 can rotate to a state parallel to the cross-section of the base 600 or the crushing chamber 200, or even closer to the crushing blade 310. Figure 4 As shown, when the battery crushing device 10 is in the normal feeding state, the pressing member 410 rotates in the direction away from the crushing tool 310 under the action of the driving mechanism until it is offset from the crushing tool 310. For example, the pressing member 410 can be rotated to a state where its extending direction is parallel to the extending direction of the feeding channel 100.

[0066] In this embodiment, the pressing component 410 is rotatably connected to the wall of the crushing chamber 200 or the feeding channel 100. The pressing component 410 is a rotary pressing structure. When switching between the first and second positions, the pressing component 410 enables automatic and continuous feeding of the battery crushing device 10 in both abnormal and normal feeding states. Simultaneously, the rotary pressing component 410 can utilize shaft sealing technology to seal the pressing mechanism 400. This shaft sealing technology is easy to implement and has a small sealing surface, significantly improving the sealing performance of the pressing mechanism 400. Compared to solutions using other motion forms for the pressing component 410, the battery crushing device 10 with the rotary pressing component 410 in this application exhibits better sealing performance.

[0067] It should be noted that, in other examples, the clamping element 410 of this application can also be a linearly moving clamping element 410. This application does not limit the specific structure of the clamping element 410.

[0068] In some examples, please refer to Figure 5 , Figure 5 This is a schematic diagram of the pressing member 410 and the crushing blade 310 provided in an embodiment of this application. The pressing member 410 is an arc-shaped structure that bends toward the crushing blade 310. For example, when the battery crushing device 10 is in an abnormal feeding state, the pressing member 410 blocks the crushing blade 310 and is in a first position. At this time, the pressing member 410 gradually moves toward the crushing blade 310 from the middle to both ends. The pressing member 410 is an arc-shaped structure that is concave toward the crushing blade 310.

[0069] The arc-shaped pressing component 410 of this application embodiment can block abnormal materials to be crushed with a higher rebound path, and the pressing component 410 can better solve the problem of abnormal feeding of materials to be crushed; at the same time, the arc-shaped pressing component 410 can also buffer abnormal materials to be crushed, reduce the collision force between the materials to be crushed and the pressing component 410, improve the service life of the pressing component 410, and avoid sparks generated by the collision between the materials to be crushed and the pressing component 410. The arc-shaped pressing component 410 can reduce the flammability and explosion risk of the crushing chamber 200.

[0070] Please refer to this again. Figures 1 to 5 In addition to the crushing cutter 310, the crushing mechanism 300 of this application embodiment may also include a crushing shaft 320 and a drive assembly 330. The crushing cutter 310 is connected to the crushing shaft 320, and the crushing shaft 320 is used to drive the crushing cutter 310 to rotate. For example, in some examples, the drive assembly 330 is connected to the crushing shaft 320, and the drive assembly 330 drives the crushing shaft 320 to drive the crushing cutter 310 to rotate and crush the material to be crushed.

[0071] It is understood that the crushing blade 310 includes a blade body (not shown in the attached drawings) and an insulating coating structure (not shown in the attached drawings), with the insulating coating structure applied to the outer surface of the blade body. Since the material to be crushed by the battery crushing device 10 is often waste batteries, and some waste batteries retain a small amount of charge, during the crushing process, the material to be crushed often carries oxygen when entering the crushing chamber 200 from the feed channel 100 and is prone to colliding with the crushing blade 310, generating sparks and increasing the risk of flammability and explosion of the battery crushing device 10. In this embodiment, an insulating coating structure is applied to the outer surface of the crushing blade 310. This insulating coating structure reduces the possibility of electrical conductivity from impact between the crushing blade 310 and the material to be crushed, and also reduces the degree of heat generation of the blade, greatly improving the safety of the crushing blade 310.

[0072] Understandably, in some examples, the blade body of the crushing tool 310 may be, but is not limited to, an impact-resistant alloy steel structure, and the insulating coating structure may be, but is not limited to, an insulating ceramic structure. In this case, the crushing tool 310 possesses both the hardness of alloy steel and the insulation and wear resistance of ceramics. The crushing tool 310 can reduce the conductivity between the waste battery and the crushing tool 310 during the crushing process, reduce the heat generation and corrosion of the crushing tool 310, and extend the service life of the crushing tool 310.

[0073] It is understood that the crushing blade 310 can, but is not limited to, receive driving force provided by means of electric motor drive, hydraulic drive, pneumatic drive, electromagnetic drive, etc. For example, the drive assembly 330 of this application includes a drive motor 331 and a gear transmission box 332. The drive motor 331 is connected to the gear transmission box 332, and the gear transmission box 332 is connected to the crushing shaft 320. The drive motor 331 drives the gear transmission box 332 and the crushing shaft 320 connected to the gear transmission box 332 to rotate, thereby driving the crushing blade 310 mounted on the crushing shaft 320 to rotate in the crushing chamber 200 to complete the crushing of waste batteries.

[0074] It is understood that the crushing tool 310 of this application is not limited to a single tool; it can be a combination of multiple tools. For example, the crushing tool 310 of this application includes a moving crusher blade and a fixed crusher blade. The fixed crusher blade is mounted on the crushing mechanism 300 and remains stationary, while the moving crusher blade is connected to a rotating shaft and rotates. Under the combined action of the moving crusher blade and the fixed crusher blade, the material to be crushed is pulverized. Both the moving crusher blade and the fixed crusher blade can have an insulating coating structure on their surfaces.

[0075] This application applies an insulating coating structure to the outer surface of the crushing tool 310. This insulating coating structure can reduce the impact and electrical conductivity between the crushing tool 310 and the material to be crushed, and can also prevent the tool from overheating, thus greatly improving the safety and service life of the crushing tool 310.

[0076] Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram of the crushing shaft 320 of the battery crushing device 10 provided in an embodiment of this application. The crushing shaft 320 has a cooling chamber 321 extending along its axial direction, which is used to connect to a cooling circulation system. The crushing shaft 320 is used for heat exchange with the cooling medium transported by the cooling circulation system.

[0077] It is understood that in some examples, the battery crushing device 10 includes a cooling circulation system; in other examples, the cooling circulation system is a structure independent of the battery crushing device 10. The cooling medium transported by the cooling circulation system may be, but is not limited to, water, oil, fluoride, etc.

[0078] Understandably, in some examples, the cooling chamber 321 of the crusher shaft 320 extends along the axial direction of the crusher shaft 320 but does not penetrate the crusher shaft 320. For example... Figure 6 As shown, the cooling circulation system is connected to the cooling chamber 321 of the crushing shaft 320 through a rotary joint 230. The rotary joint 230 has an inlet 231 and an outlet 232 that are connected to and separate from the cooling chamber 321. The cooling medium can enter the cooling chamber 321 from the inlet 231 and flow out of the cooling chamber 321 after exiting the outlet. During the flow process, the crushing shaft 320 and the cooling medium exchange heat, thereby realizing the cooling operation of the crushing shaft 320.

[0079] Of course, in other examples, the cooling chamber 321 of the crusher shaft 320 can also extend along the axial direction of the crusher shaft 320 and penetrate through the crusher shaft 320. In this case, an inlet 231 can be provided at one end of the cooling chamber 321 of the crusher shaft 320, and an outlet 232 can be provided at the other end of the cooling chamber 321. The embodiments of this application do not limit the specific structure of the cooling chamber 321 opened inside the crusher shaft 320.

[0080] The cooling circulation system of this application embodiment transmits cooling medium to the cooling chamber 321 of the crushing shaft 320, which can cool the crushing shaft 320 in real time. This ensures that the crushing shaft 320 is not affected by excessive temperature, thus maintaining its working efficiency and service life. It also avoids the risk of the crushing chamber 200 becoming flammable and explosive due to excessive temperature of the crushing shaft 320.

[0081] Please refer to this again. Figure 3 and Figure 4In some embodiments, the crushing chamber 200 has a cooling channel 210 inside its wall. The wall of the crushing chamber 200 has a double-layer structure, with the cooling channel 210 formed between the inner and outer walls. This cooling channel 210 is used to communicate with a cooling circulation system, allowing the wall of the crushing chamber 200 to exchange heat with the cooling medium transported by the cooling circulation system. This can both cool the crushing chamber 200 and reduce noise during the crushing process of the battery crushing device 10.

[0082] Of course, in some other embodiments, the battery crushing device 10 also includes a cooling jacket 220, which is sleeved on the outside of the crushing chamber 200. The cooling jacket 220 is used to communicate with the cooling circulation system, and the crushing chamber 200 exchanges heat with the cooling medium transmitted by the cooling circulation system through the cooling jacket 220. In this case, the cooling jacket 220 can both cool the crushing cooling chamber 321 and reduce noise during the crushing process.

[0083] Please refer to this again. Figures 1 to 6 The battery crushing device 10 also includes a feeding mechanism 700. The feeding mechanism 700 is disposed on the feeding channel 100. The feeding mechanism 700 includes a first blocking member 710 and a second blocking member 720 arranged sequentially at intervals along the extension direction of the feeding channel 100. The first blocking member 710 and the second blocking member 720 divide the feeding channel 100 into a first part 120, a second part 130 and a third part 140 arranged sequentially along the extension direction of the feeding channel 100.

[0084] Understandably, the second part 130 is located between the first part 120 and the third part 140, with the first part 120 near the feed inlet 110 and the third part 140 near the crushing chamber 200. The first blocking member 710 and the second blocking member 720 can move alternately relative to the feed channel 100 to control the opening and closing of each part. Specifically, when the first blocking member 710 blocks the connection between the first part 120 and the second part 130, the second part 130 and the third part 140 are connected; when the second blocking member 720 blocks the connection between the second part 130 and the third part 140, the first part 120 and the second part 130 are connected.

[0085] Understandably, when the first blocking member 710 moves to at least partially offset from the feed channel 100 and allows the first part 120 and the second part 130 to conduct, the second blocking member 720 can move to block the feed channel 100 and prevent the second part 130 from conducting with the third part 140. At this time, the material to be crushed enters the first part 120 and the second part 130 from the feed inlet 110 of the feed channel 100. Simultaneously, the third part 140 and the crushing chamber 200 are isolated from the first part 120 and the second part 130, thus achieving a seal between the third part 140 and the crushing chamber 200. In this process, the battery crushing device 10 also includes an inert gas injection mechanism (not shown in the attached figure). An inert gas injection port (not shown in the attached figure) can also be provided on the feed channel 100. The inert gas injection port is at least connected to the second part 130 of the feed channel 100. The inert gas transmitted by the inert gas injection mechanism enters the second part 130 through the inert gas injection port and dilutes the oxygen carried by the material to be crushed entering from the feed port 110, thereby reducing the oxygen concentration carried by the material to be crushed and reducing the risk of flammability and explosion when the material to be crushed is crushed by the crushing mechanism 300. When the oxygen concentration carried by the material to be crushed is extremely low, the first blocking member 710 moves to block the feed channel 100 and block the connection between the first part 120 and the second part 130 to prevent the introduction of new oxygen by new material to be crushed. Next, the second blocking member 720 moves to at least partially offset from the feed channel 100, making the second part 130 and the third part 140 connected. The second part 130, the third part 140, and the crushing chamber 200 are isolated from the first part 120, thus achieving a seal. At this time, the material to be crushed, diluted by the inert gas, can enter the crushing chamber 200 through the second part 130 and the third part 140 and be crushed by the crushing mechanism 300. Therefore, through the alternating movement of the first blocking member 710 and the second blocking member 720, the battery crushing device 10 of this application can achieve continuous feeding of the material to be crushed, and achieve dynamic sealing of the feed channel 100 during the feeding process.

[0086] Understandably, in some examples, the first blocking member 710 and the second blocking member 720 can simultaneously block the feed channel 100. For example, when the battery crushing device 10 starts working, the first blocking member 710 and the second blocking member 720 of the feeding mechanism 700 move to block the feed channel 100. The second part 130 is isolated from the first part 120 and the third part 140. The second part 130 is a sealed space. At this time, the inert gas injection mechanism can fill the second part 130 with a large amount of inert gas. The pressure detection mechanism, such as the pressure detection mechanism 920 described later, can detect the gas pressure in the second part 130 at this time. When the detected gas pressure meets the requirements and the concentration of inert gas meets the requirements, the battery crushing device 10 continues to alternately control the first blocking member 710 and the second blocking member 720. The inert gas filling the second part 130 dilutes the oxygen carried by the material to be crushed, thereby realizing continuous dynamic sealed feeding of the material to be crushed.

[0087] It is understood that the inert gas injected by the inert gas injection mechanism can be, but is not limited to, helium, ammonia, neon, argon, etc. For example, the inert gas injection mechanism in this embodiment injects ammonia into the feed channel 100. In addition to being connected to the second part 130 of the feed channel 100, the inert gas injection port can also be connected to other areas of the feed channel 100, the crushing chamber 200, etc. The inert gas can further dilute the oxygen, thereby greatly reducing the flammability and explosion risk of the crushing chamber 200.

[0088] It is understandable that in some examples, the first part 120, the second part 130, and the third part 140 of the feed channel 100 are an integral structure. In other examples, the first part 120 and the second part 130 of the feed channel 100 are an integral structure, while the third part 140 is independent of the first part 120 and the second part 130, and the third part 140 is connected and communicates with the second part 130, so that the three form the feed channel 100. Of course, in still other examples, the first part 120, the second part 130, and the third part 140 are all independent structures, and the three are connected and assembled to form the feed channel 100. It should be noted that the connection gaps between the feed channel 100, the crushing chamber 200, and the discharge channel 500 of the battery crushing device 10 in this application embodiment, as well as the gaps between the individual components of the feed channel 100, the crushing chamber 200, and the discharge channel 500, are all designed to be sealed in order to improve the sealing performance of the battery crushing device 10.

[0089] It is understood that the first blocking member 710 and the second blocking member 720 can be a double-gate structure. The feeding mechanism 700 may also include a drive structure (not shown in the figure) for driving the first blocking member 710 and the second blocking member 720 to move. This drive structure may be, but is not limited to, a motor structure, a hydraulic structure, a pneumatic structure, an electromagnetic structure, etc.

[0090] Understandably, please refer to this again. Figures 1 to 4 The battery crushing device 10 of this application embodiment may further include a support frame 800, which is fixedly mounted on the base 600 and supports the inclined feed channel 100. The support frame 800 increases the installation stability of the feed channel 100.

[0091] The battery crushing device 10 of this application embodiment is equipped with a first blocking member 710 and a second blocking member 720 that can move alternately, achieving dynamic sealing of the feed channel 100 and reducing the flammability and explosion risk of the crushing chamber 200. Simultaneously, the injection of inert gas into the feed channel 100 prevents oxidation, exothermic reactions, and combustion, further reducing the flammability and explosion risk of the crushing chamber 200 and greatly improving the safety of the battery crushing device 10. The battery crushing device 10 of this application can achieve charged crushing of old batteries.

[0092] Please refer to the following: Figure 7 , Figure 7 This is another structural schematic diagram of the battery crushing device 10 provided in an embodiment of this application. The battery crushing device 10 in this embodiment of the application further includes at least one of the following: a venting mechanism 910, a pressure detection mechanism 920, a spraying mechanism 930, a temperature detection mechanism 940, an oxygen content detection mechanism 950, and a flame detection mechanism 960.

[0093] The explosion relief mechanism 910 is connected to the crushing chamber 200. When the pressure inside the crushing chamber 200 exceeds a pressure threshold, the explosion relief mechanism 910 releases pressure outward to relieve the explosion and reduce the pressure inside the crushing chamber 200 below the pressure threshold. In some examples, the explosion relief mechanism 910 can also be linked with the control system of the battery crushing device 10. Once the explosion relief mechanism 910 releases pressure outward to relieve the explosion, the control system can control the battery crushing device 10 to shut down in an emergency. In some examples, the explosion relief mechanism 910 can be installed in the third part 140 of the feed channel 100, so that the third part 140 is reused as the explosion relief chamber of the explosion relief mechanism 910. The battery crushing device 10 of this application embodiment is equipped with an explosion relief mechanism 910, which can reduce the risk of explosion caused by excessive pressure in the crushing chamber 200 of the battery crushing device 10, and the safety of the battery crushing device 10 is higher.

[0094] At least a portion of the pressure detection mechanism 920 is located within the crushing chamber 200, and the pressure detection mechanism 920 can detect the pressure within the crushing chamber 200. In some examples, the pressure detection mechanism 920 can be electrically connected to the explosion venting mechanism 910, or both the pressure detection mechanism 920 and the explosion venting mechanism 910 can be electrically connected to the control system of the battery crushing device 10, so as to realize the linkage between the pressure detection mechanism 920 and the explosion venting mechanism 910. When the pressure in the crushing chamber 200 detected by the pressure detection mechanism 920 exceeds the pressure threshold, the explosion venting mechanism 910 releases pressure outward to achieve explosion venting. In other examples, at least a portion of the pressure detection mechanism 920 may also be located within the feed channel 100. For example, at least a portion of the pressure detection mechanism 920 may also be located in the second part 130 of the feed channel 100. The pressure detection mechanism 920 can detect the pressure of the inert gas injected into the second part 130 to determine whether the concentration of the injected inert gas meets the requirements. When the concentration of the inert gas meets the requirements, the battery crushing device 10 continues to alternately control the first blocking member 710 and the second blocking member 720. The inert gas filled in the second part 130 can dilute the oxygen carried by the material to be crushed, thereby realizing continuous dynamic sealed feeding of the material to be crushed.

[0095] At least a portion of the oxygen content detection mechanism 950 is located within the crushing chamber 200, and the oxygen content detection mechanism 950 can detect the oxygen content within the crushing chamber 200. When the oxygen content within the crushing chamber 200 exceeds an oxygen content threshold, the battery crushing device 10 can control the inert gas injection mechanism to inject more inert gas into the crushing chamber 200 to dilute the oxygen and ensure the safety of the crushing chamber 200. In other examples, at least a portion of the oxygen content detection mechanism 950 is also located within the feed channel 100, for example, within the second portion 130 of the feed channel 100. The oxygen content detection mechanism 950 can also detect the oxygen content within the second portion 130, and when the detected oxygen content exceeds an oxygen content threshold, the battery crushing device 10 controls the inert gas injection mechanism to inject more inert gas into the second portion 130 to dilute the oxygen, thereby improving the safety of the battery crushing device 10.

[0096] At least a portion of the temperature detection mechanism 940 is located within the crushing chamber 200, and the temperature detection mechanism 940 can detect the temperature within the crushing chamber 200. When the temperature detection mechanism 940 detects that the temperature of the crushing chamber 200 is too high, the battery crushing device 10 can control the flow rate of the cooling medium transmitted by the cooling circulation system to achieve rapid cooling of the crushing chamber 200 and the crushing shaft 320. Of course, when the temperature detection mechanism 940 detects that the temperature of the crushing chamber 200 is too high, the battery crushing device 10 can also control the operation of at least one of the explosion relief mechanism 910 and the spraying mechanism 930 to reduce the temperature of the crushing chamber 200 by injecting inert gas, spraying, etc., thereby improving the safety of the battery crushing device 10.

[0097] At least a portion of the flame detection mechanism 960 is located within the crushing chamber 200, and the flame detection mechanism 960 can detect whether an open flame is generated within the crushing chamber 200. The flame detection mechanism 960 can determine the presence of a flame by means of, but not limited to, detecting light radiation, ultraviolet light, infrared light, smoke and gas analysis, and sound detection.

[0098] At least a portion of the spray mechanism 930 is located within the crushing chamber 200. The spray mechanism 930 can spray at least one of a fire extinguishing medium and a cooling medium into the crushing chamber 200 when an open flame is generated within the crushing chamber 200 or when the temperature of the crushing chamber 200 is too high. For example, the spray mechanism 930 can spray water into the crushing chamber 200 to extinguish the fire and cool the crushing chamber 200.

[0099] The battery crushing device 10 of this application embodiment is equipped with a deflation mechanism 910, a pressure detection mechanism 920, a spray mechanism 930, a temperature detection mechanism 940, an oxygen content detection mechanism 950, a flame detection mechanism 960, etc. The battery crushing device 10 detects parameters such as pressure, temperature, oxygen content, and flame in the crushing chamber 200. The spray mechanism 930, as an emergency mechanism, can extinguish open flames generated in the crushing chamber 200 in a timely manner. Thus, the safety of the battery crushing device 10 is further improved through the working action of multiple mechanisms.

[0100] Based on the above description, this application also provides a battery recycling system, including the battery crushing device 10 of any of the above embodiments.

[0101] It is understood that the battery recycling system is used to perform operations such as discharging, crushing, and sorting of waste batteries. In some examples, the battery recycling system also includes a feeding device, a sorting device, and a pollutant treatment device. The feeding device is connected to the battery crushing device 10 and is used to feed the material to be crushed (e.g., waste lithium batteries) to the battery crushing device 10. The battery crushing device 10 is used to crush the material to be crushed and obtain pyrolytic material. The sorting device is connected to the battery crushing device 10 and is used to sort the pyrolytic material and separate magnetic material, heavy material, and non-magnetic light material; the sorting device is also used to sort the non-magnetic light material, separating substances such as black powder, aluminum, and copper in sequence. The pollutant treatment device is connected to the battery crushing device 10 and the sorting system respectively. The pollutant treatment device is used to perform pollution-free treatment of dust and flue gas generated during the recycling process and to collect black powder from the dust and flue gas. It should be noted that the battery recycling system may also include other structures, and the specific structure of the battery recycling system is not limited in the embodiments of this application.

[0102] Based on the above description of the battery crushing device 10 and the battery recycling system, the battery crushing device 10 and the battery recycling system of the present application embodiment have the following advantages:

[0103] 1. The feeding channel 100 is inclined relative to the crushing chamber 200. The material to be crushed can automatically enter the crushing chamber 200 along the inclined feeding channel 100 under its own gravity and be crushed by the crushing blades 310 in the crushing chamber 200. The battery crushing device 10 can realize automatic feeding of the material to be crushed, which greatly improves the feeding efficiency of the battery crushing device 10.

[0104] 2. When the battery crushing device 10 is in an abnormal feeding state, the pressing component 410 blocks at least part of the crushing blade 310. The pressing component 410 can prevent the abnormal material to be crushed from rebounding if it is not crushed by the crushing blade 310. Furthermore, when the pressing component 410 moves in the direction toward the crushing blade 310, it can apply pressure to the abnormal material to be crushed, causing the crushing blade 310 to crush the abnormal material to be crushed. Under the action of the pressing component 410, the battery crushing device 10 of this application solves the problem of abnormal feeding of the material to be crushed more efficiently.

[0105] 3. The cooling circulation system transmits cooling medium to the cooling chamber 321 of the crushing shaft 320 of the crushing mechanism 300, which can cool the crushing shaft 320 in real time; at the same time, the cooling circulation system transmits cooling medium to the cooling channel 210 or cooling jacket 220 of the crushing chamber 200, which can cool the crushing chamber 200 in real time. Thus, the battery crushing device 10 of this application can solve the problem of overheating of the crushing shaft 320 and the crushing chamber 200, and at the same time reduce the noise problem generated during the crushing process.

[0106] 4. The connection gaps between the feed channel 100, the crushing chamber 200, and the discharge channel 500 of the battery crushing device 10 are all sealed, making it difficult for air to enter the crushing chamber 200. The feed channel 100 and the crushing chamber 200 are filled with a large amount of inert gas. The first blocking member 710 and the second blocking member 720 move alternately to achieve dynamic sealing of the feed channel 100 and the crushing chamber 200, effectively diluting the oxygen carried by the material to be crushed during feeding. The crushing blades 310 of the crushing mechanism 300 are equipped with an insulating coating structure, making it difficult for the crushing blades 310 to collide with the material to be crushed and generate sparks. The battery crushing device 10 is also equipped with a spray mechanism 930, which can quickly extinguish any open flame generated in the crushing chamber 200. Therefore, the battery crushing device 10 of this application can achieve the crushing of charged materials, greatly reducing the risk of flammability and explosion.
