Description

A vehicle-mounted crushing equipment Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted waste battery recycling equipment, and in particular to a vehicle-mounted crushing equipment. Background Art

[0002] The greatest difficulty in recycling used power batteries lies in the potential for fire and explosion during the crushing process. Live battery crushing, meaning the crushing of undischarged batteries, creates local short circuits. This heat release leads to a chain reaction of exothermic reactions within the battery. Even in oxygen-deficient conditions, the battery can generate oxygen and cause combustion during crushing, causing some of the electrolyte to evaporate and volatilize, leaving the remaining electrolyte in liquid form. This increases the risk of live battery crushing and reduces safety, especially when performed on-board.

[0003] Thermite reaction: NCM+Al+O2→Li x Al y O z +Me+MeO;

[0004] Electrolyte combustion reaction: 2C3H4O3(EC)+5O2→6CO2+4H2O;

[0005] Decomposition reaction of positive electrode material: Li 0.5 MeO2→1 / 2LiMeO2+1 / 6Me3O4+1 / 6O2↑;

[0006] SEI film decomposition: (CHOCOOLi)2→Li2CO3+C2H4↑+CO2↑+1 / 2O2↑.

[0007] Furthermore, in the case of vehicle-mounted crushing, waste power cells are crushed on vehicle-mounted crushing equipment. This equipment must be transported and pre-processed for the waste power cells. However, the crushed material from traditional vehicle-mounted crushing equipment contains a high amount of electrolyte, which results in poor initial separation of the electrolyte from the crushed material during the crushing process.

[0008] Summary of the Invention

[0009] Based on this, it is necessary to provide a vehicle-mounted crushing equipment that has good crushing safety and can improve the initial separation effect of the electrolyte in the crushed material.

[0010] A vehicle-mounted crushing device, comprising:

[0011] Car body;

[0012] The crushing mechanism includes a crushing box, a filter plate, a sliding door assembly and a crushing assembly; the crushing box is installed in the vehicle body, a crushing chamber is provided in the crushing box, and a feeding port connected to the crushing chamber is provided on the top of the crushing box; an oxygen concentration sensor is provided in the crushing chamber; the filter plate is transversely arranged in the crushing chamber and connected to the inner wall of the crushing box to separate the crushing chamber into a crushing main chamber and an evaporation chamber in the upper and lower parts; the filter plate is provided with a plurality of spaced liquid holes, and a side wall of the crushing box is provided with a discharge port connected to the crushing main chamber; the sliding door assembly is slidably connected to the crushing box, and the sliding door assembly is used to open or close the discharge port; the crushing assembly is installed at the feeding port, and the crushing assembly is used to crush the batteries;

[0013] a nitrogen supply mechanism, comprising a nitrogen pipe body and a supply control valve, wherein one end of the nitrogen pipe body is in communication with the crushing main chamber, and the other end of the nitrogen pipe body is connected to an external nitrogen source; the supply control valve is provided on the nitrogen pipe body, and a control end of the supply control valve is electrically connected to the oxygen concentration sensor; the supply control valve is configured to open when the oxygen concentration in the crushing chamber is equal to a preset concentration threshold;

[0014] An exhaust gas treatment mechanism is located in the vehicle body and is communicated with the main crushing chamber and the evaporation chamber respectively. The exhaust gas treatment mechanism is used to buffer and treat the exhaust gas.

[0015] Compared with the related art, the present disclosure has at least the following advantages:

[0016] 1. The above-mentioned vehicle-mounted crushing equipment senses the oxygen concentration in the crushing main chamber through an oxygen concentration sensor. When the oxygen concentration sensor generates a sensing signal, the supply control valve opens, allowing the nitrogen source to supply nitrogen to the crushing main chamber through the nitrogen pipe body; otherwise, the supply control valve closes, avoiding the problem of the nitrogen pipe body continuously supplying nitrogen to the crushing main chamber; in this way, the oxygen concentration in the crushing main chamber is always lower than the preset concentration threshold, avoiding the situation where the positive electrode material or SEI film decomposes and produces oxygen and burns during the battery crushing process, thereby improving the crushing safety of the battery.

[0017] 2. During the crushing process, the sliding door assembly can always be closed at the discharge port, so that the oxygen concentration in the crushing main chamber is more accurate. At the same time, injecting nitrogen into the crushing main chamber during the crushing period can quickly and effectively reduce the oxygen concentration in the crushing main chamber and reduce the nitrogen consumption, thereby reducing the cost required for battery crushing and recycling.

[0018] 3. When the crushing is completed, the gas in the crushing main chamber and the evaporation chamber can be extracted through the exhaust gas treatment mechanism to ensure the safety of the subsequent sliding door assembly opening at the discharge port; after the sliding door assembly is opened at the discharge port, the crushed waste can be discharged through the discharge port, thereby improving the safety of the vehicle-mounted crushing equipment.

[0027] As shown in FIG1 to FIG3 , a vehicle-mounted crushing device 10 according to an embodiment is used to crush battery cells. Before crushing, the battery pack can be disassembled manually or with a battery pack disassembly device to remove the battery cells.

[0028] In one embodiment, a vehicle-mounted crushing device 10 includes a vehicle body 100, a crushing mechanism 200, a nitrogen supply mechanism 300, and an exhaust gas treatment mechanism 400. The crushing mechanism 200 includes a crushing box 210, a filter plate 220, a sliding door assembly 230, and a crushing assembly 240. The crushing box 210 is installed within the vehicle body 100 and defines a crushing chamber 202. A feeding port 204 is defined at the top of the crushing box 210 and communicates with the crushing chamber 202. During use, used batteries are fed into the crushing box 210 through the feeding port 204 at the top of the crushing box 210.

[0029] As shown in Figures 1 to 3, in one embodiment, a filter plate 220 is disposed transversely within the crushing chamber 202 and connected to the inner wall of the crushing box 210, thereby dividing the crushing chamber 202 into a main crushing chamber 2022 and an evaporation chamber 2024. In this embodiment, the main crushing chamber 2022 is connected to the feeding port 204. A crushing assembly 240 is installed at the feeding port 204. The crushing assembly 240 is used to crush the batteries. The crushing assembly 240 crushes the used battery cells within the main crushing chamber 2022, and the resulting crushed material falls onto the filter plate 220. The filter plate 220 is provided with a plurality of spaced-apart liquid passage holes 222, allowing the electrolyte in the crushed material to flow into the evaporation chamber 2024 through the liquid passage holes 222.

[0030] As shown in Figures 1 to 3, in one embodiment, a discharge port 206 is formed on the sidewall of the crushing box 210 and communicates with the main crushing chamber 2022, allowing crushed material on the filter plate 220 to be discharged through the discharge port 206. A sliding door assembly 230 is slidably connected to the crushing box 210 and is used to open and close the discharge port 206. When the crushing assembly 240 is crushing the used battery cells, the sliding door assembly 230 can close the discharge port 206. When the crushing assembly 240 has completed crushing the used battery cells, the sliding door assembly 230 can open the discharge port 206 to discharge the crushed material through the discharge port 206. This ensures that the batteries are more sealed during the crushing process by the crushing assembly 240 within the main crushing chamber 2022, thereby ensuring a safer battery crushing process.

[0031] As shown in Figures 1 to 3, in one embodiment, an oxygen concentration sensor 2023 is installed within the crushing chamber 202. The oxygen concentration sensor 2023 is used to sense the oxygen concentration within the crushing chamber 202. A nitrogen supply mechanism 300 includes a nitrogen pipe 310 and a supply control valve 320. One end of the nitrogen pipe 310 communicates with the crushing chamber 202, and the other end of the nitrogen pipe 310 is connected to an external nitrogen source. The supply control valve 320 is installed within the nitrogen pipe 310, and the control end of the supply control valve 320 is electrically connected to the oxygen concentration sensor 2023. The supply control valve 320 is configured to open when the oxygen concentration within the crushing chamber 202 reaches a preset concentration threshold. Specifically, when the oxygen concentration within the crushing chamber 202 reaches the preset concentration threshold, the oxygen concentration sensor 2023 generates a sensing signal, and the control end of the supply control valve 320 controls the supply control valve 320 to open. In this embodiment, the nitrogen pipe 310 is connected to the main crushing chamber 2022. When the oxygen concentration sensor 2023 generates a sensing signal, the supply control valve 320 opens to inject nitrogen into the crushing chamber 202, thereby reducing the oxygen concentration within the crushing chamber 202 and improving the safety of the used battery cells during the crushing process. The exhaust gas treatment mechanism 400 is located within the vehicle body 100 and is connected to the main crushing chamber 2022 and the evaporation chamber 2024. The exhaust gas treatment mechanism 400 is used to buffer and treat the exhaust gas.

[0032] In the above-mentioned vehicle-mounted crushing device 10, since the crushing main chamber 2022 is connected to one end of the nitrogen tube body 310, the other end of the nitrogen tube body 310 is connected to an external nitrogen source, and the control end of the supply control valve 320 is electrically connected to the oxygen concentration sensor 2023, the oxygen concentration in the crushing main chamber 2022 is sensed by the oxygen concentration sensor 2023. When the oxygen concentration sensor 2023 generates a sensing signal, the supply control valve 320 is opened, allowing the nitrogen source to supply nitrogen to the crushing main chamber 2022 through the nitrogen tube body 310; otherwise, the supply control valve 320 is closed, thereby avoiding the problem of the nitrogen tube body 310 continuously supplying nitrogen to the crushing main chamber 2022. In this way, the oxygen concentration in the crushing main chamber 2022 is always lower than the preset concentration threshold, avoiding the situation where the positive electrode material or SEI film decomposes and produces oxygen and burns during the battery crushing process, thereby improving the crushing safety of the battery.

[0033] Furthermore, during the crushing process, the sliding door assembly 230 can remain closed at the discharge port 206, ensuring a more accurate oxygen concentration within the crushing main chamber 2022. Furthermore, injecting nitrogen into the crushing main chamber 2022 during the crushing process can quickly and effectively reduce the oxygen concentration within the crushing main chamber 2022 and reduce nitrogen consumption, thereby lowering the cost of battery crushing and recycling. Upon completion of the crushing process, the exhaust gas treatment mechanism 400 can first extract the gases within the crushing main chamber 2022 and the evaporation chamber 2024, ensuring the safety of the subsequent opening of the sliding door assembly 230 at the discharge port 206. Once the sliding door assembly 230 is open at the discharge port 206, the crushed waste can be discharged through the discharge port 206, thereby improving the safety of the vehicle-mounted crushing apparatus 10. In one embodiment, the exhaust gas treatment mechanism 400 can buffer and treat the exhaust gas, preventing direct discharge of the exhaust gas and environmental pollution.

[0034] In the main crushing chamber 2022, the crushed waste obtained by the crushing assembly 240 falls onto the filter plate 220. Since the filter plate 220 is provided with a plurality of spaced liquid holes 222, the electrolyte in the crushed waste flows into the evaporation chamber 2024 through the filter holes, thereby reliably separating the crushed material and the electrolyte of the crushed waste, avoiding the problem of the crushed material being mixed with a large amount of electrolyte, and improving the initial separation effect of the electrolyte in the crushed material.

[0035] As shown in FIG. 1 to FIG. 3 , in one embodiment, the nitrogen supply mechanism 300 further includes a nitrogen source box 330 , and the nitrogen pipe body 310 is connected to the nitrogen source box, so that the nitrogen in the nitrogen source box 330 passes through the nitrogen pipe body 310 into the crushing main chamber 2022 .

[0036] As shown in Figures 1 to 3, in one embodiment, a heating module 2025 is provided on the inner bottom wall of the evaporation chamber 2024, so that the heating module 2025 heats and evaporates the electrolyte in the evaporation chamber 2024, thereby improving the efficiency of electrolyte evaporation, avoiding the problem of accidental risks caused by long-term retention of electrolyte in the evaporation chamber 2024, and further improving the safety of the vehicle-mounted crushing equipment 10.

[0037] As shown in Figures 1 to 3, in one embodiment, the heating temperature of heating module 2025 is between 100°C and 200°C, enabling heating module 2025 to effectively heat and evaporate the electrolyte. In one embodiment, heating module 2025 is provided with a heating surface 2026, which is equipped with a temperature sensor 2027. Temperature sensor 2027 is electrically connected to a control terminal of heating module 2025. When temperature sensor 2027 senses that the temperature of heating surface 2026 reaches a first predetermined value, heating module 2025 begins heating. When temperature sensor 2027 senses that the temperature of heating surface 2026 reaches a second predetermined value, heating module 2025 stops heating. This maintains the heating temperature of heating surface 2026 within a predetermined range, enabling heating module 2025 to effectively heat and evaporate the electrolyte. In this embodiment, the first predetermined value is greater than or equal to 100°C. The second predetermined value is greater than the first predetermined value and less than or equal to 200°C.

[0038] In one embodiment, the preset concentration threshold is less than or equal to 3%, so that the battery crushing process is safer. In this embodiment, the preset concentration threshold is equal to 3%.

[0039] As shown in FIG3 , in one embodiment, the filter plate 220 is tilted along a first preset angle θ1, so that the electrolyte can flow out of the crushed material better, thereby enabling the filter plate 220 to better separate the crushed material of the crushed waste from the electrolyte, while improving the smoothness and discharge rate of subsequent crushed material.

[0040] As shown in FIG3 , in one embodiment, the first preset angle θ1 is 3° to 10°. In this embodiment, the first preset angle θ1 is 5°, which allows for better separation of the crushed material from the electrolyte and facilitates subsequent discharge of the crushed material.

[0041] As shown in FIG3 , in one embodiment, the vehicle-mounted crushing equipment 10 further includes a pushing mechanism 500, which is used to push the crushed material on the filter plate 220 through the discharge port 206 after the sliding door assembly 230 is opened at the discharge port 206. This does not require manual intervention, and the crushed material can be automatically discharged easily, thereby improving the discharge efficiency of the crushed material. In one embodiment, the pushing mechanism 500 includes a pushing drive assembly 510 and a pushing scraper 520. The pushing drive assembly 510 is installed on the outside of the crushing box 210. The crushing box 210 is provided with a sliding hole 212 connected to the crushing main chamber 2022. The telescopic rod body of the pushing drive assembly 510 is passed through the sliding hole 212 and is slidably connected to the crushing box 210. The pushing scraper 520 is located in the crushing main chamber 2022 and is connected to the telescopic rod body. The pushing scraper 520 is located on the upper side of the filter plate 220. The pushing drive assembly 510 drives the pushing scraper 520 to move toward or away from the discharge port 206. When the pushing mechanism 500 pushes the crushed material off the filter plate 220, the pushing drive assembly 510 first drives the pushing scraper 520 toward the discharge port 206, causing the pushing scraper 520 to push the crushed material off the filter plate 220. The pushing drive assembly 510 then drives the pushing scraper 520 away from the discharge port 206, thereby resetting the pushing scraper 520. In one embodiment, the pushing drive assembly 510 is a cylinder drive assembly or a motor drive assembly. In this embodiment, the pushing drive assembly 510 is a cylinder drive assembly.

[0042] In one embodiment, the telescopic rod is slidably and hermetically connected to the crushing box 210, thereby achieving a sliding connection between the telescopic rod and the crushing box 210 and improving the sealing performance of the sliding connection between the telescopic rod and the crushing box 210. In this embodiment, a sealing sleeve (not shown) is disposed within the sliding hole 212 and slidably sleeved on the telescopic rod body, thereby achieving a sliding and hermetically connected telescopic rod to the crushing box 210.

[0043] As shown in Figure 3, in one embodiment, the direction in which the push drive assembly 510 drives the push scraper 520 to move is parallel to the extension direction of the filter plate 220, that is, the direction in which the push drive assembly 510 drives the push scraper 520 to move is parallel to the plane where the filter plate 220 is located, so that the push scraper 520 can better push the crushed material on the filter plate 220 away.

[0044] As shown in Figures 2 to 4, in one embodiment, the vehicle-mounted crushing equipment 10 also includes a material pre-separation mechanism 600, which includes a material pre-separation mechanism 600 including a material pre-separation guide plate 610 and a material receiving box 620; the material pre-separation guide plate 610 is connected to the crushing box 210 at an inclined angle of a second preset angle, and the material receiving box 620 is located on the lower side of the material pre-separation guide plate 610. The material receiving box 620 is provided with a crushing material trough 622 and a powder material trough 624. One end of the material pre-separation guide plate 610 extends to the discharge port 206, and the other end of the material pre-separation guide plate 610 extends to the crushing material trough 622, so that the crushed material can pass through the discharge port 206 and slide better along the material pre-separation guide plate 610 to the crushing material trough 622. In one embodiment, a plurality of screening apertures 612 are spaced apart at a portion of the material discharge guide plate 610 adjacent to the material discharge port 206, and the plurality of screening apertures 612 are all arranged corresponding to the powder trough 624, so that the powder in the crushed material first passes through the plurality of screening apertures 612 and falls into the powder trough 624 during the process of the crushed material being discharged along the material discharge guide plate 610. In this way, the powder in the crushed material and other substances are simultaneously pre-separated during the discharge, thereby improving the efficiency of battery crushing and recycling.

[0045] As shown in Figures 2 to 4, in one embodiment, the material guide plate 610 is welded to the crushing box 210, thereby being fixedly connected to the crushing box 210. It will be appreciated that in other embodiments, the material guide plate 610 is not limited to being welded to the crushing box 210. For example, the material guide plate 610 can be rotatably connected to the outer wall of the crushing box 210, and a support member can be provided on the outer periphery of the crushing box 210, which supports the material guide plate 610. When in use, the support member can be supported by the material guide plate 610, allowing the material guide plate 610 to reliably guide the discharge of crushed material. When not in use, the support member can be rotated to a vertical position, that is, rotated to a position parallel to the outer wall of the crushing box 210, thereby reducing the footprint of the material guide plate 610. In one embodiment, the vehicle-mounted crushing equipment 10 further includes a vibration assembly mounted on the outer wall of the crushing box 210. The power output end of the vibration assembly is connected to the material discharge guide plate 610 to vibrate the material discharge guide plate 610 during material discharge, thereby enabling the material discharge guide plate 610 to better discharge the crushed material. In this embodiment, the vibration assembly is an ultrasonic vibration assembly.

[0046] As shown in Figures 2 to 4, in one embodiment, the second preset angle θ2 is 8° to 20°, so that the material guide plate 610 can better discharge the crushed material. In this embodiment, the second preset angle θ2 is 16°.

[0047] As shown in FIG4 , in one embodiment, the plurality of sieving apertures 612 are arranged in a rectangular array, allowing the powder in the crushed material to pass through the discharge guide plate 610 and fall into the powder trough 624, thereby effectively pre-separating the powder in the crushed material from other substances. It is understood that in other embodiments, the plurality of sieving apertures 612 are arranged in a circular array.

[0048] As shown in Figures 2 to 4, in one embodiment, the material pre-dividing mechanism 600 further includes a first enclosing plate 630 and a second enclosing plate 640. The first enclosing plate 630 and the second enclosing plate 640 are respectively connected to the two sides of the material discharging guide plate 610, so that the material discharging guide plate 610, the first enclosing plate 630, and the second enclosing plate 640 collectively form a material guide channel 602. One end of the first enclosing plate 630 extends to the material discharge port 206, and the other end of the first enclosing plate 630 extends to the crushing trough 622. One end of the second enclosing plate 640 extends to the material discharge port 206, and the other end of the second enclosing plate 640 extends to the crushing trough 622, so that the crushed material can be discharged better along the material guide channel 602. In this embodiment, the first enclosing plate 630 and the second enclosing plate 640 are respectively welded to the two sides of the material discharging guide plate 610.

[0049] As shown in Figures 2 to 4, in one embodiment, the exhaust gas treatment mechanism 400 includes an exhaust buffer component 410 and a gas purification component 420. The exhaust buffer component 410 includes an exhaust pump 412, an exhaust pipe body 414 and a compression buffer 416. The compression buffer 416 is installed in the vehicle body 100. One end of the exhaust pipe body 414 is respectively connected to the crushing main chamber 2022 and the evaporation chamber 2024, and the other end of the exhaust pipe body 414 is connected to the air inlet end of the buffer. The exhaust pump 412 is provided on the exhaust pipe body 414. The gas purification component 420 is connected to the air outlet end of the compression buffer 416. The compression buffer 416 is used to compress and store the exhaust gas. When the crushing assembly 240 completes crushing the battery, the exhaust pump 412 extracts the exhaust gas from the crushing main chamber 2022 and the evaporation chamber 2024 through the exhaust pipe body 414 to the compression buffer 416 for buffering, waiting for subsequent processing; and, the exhaust gas is discharged to the gas purification assembly 420 for processing through the compression buffer 416. Due to the temporary gas storage function of the compression buffer 416, the gas purification assembly 420 can flexibly process the exhaust gas in batches, reducing the processing energy consumption and processing pressure of the gas purification assembly 420.

[0050] In one embodiment, the compression buffer 416 is also provided with an external pipe body and an external control valve provided on the external pipe body. The external pipe body can be connected to an external waste gas treatment device. For example, when the waste gas treatment station is reached, the external pipe body is connected to the access pipe of the waste gas treatment station for centralized treatment, thereby improving the ease of use of the vehicle-mounted crushing equipment 10.

[0051] As shown in FIG2 , in one embodiment, a fixing hole communicating with the crushing main chamber 2022 is opened on the outer wall of the crushing box 210 . The fixing hole is arranged adjacent to the feeding port 204 . The nitrogen pipe body 310 is passed through the fixing hole and is sealedly connected to the crushing box 210 .

[0052] As shown in Figures 2 and 5, in one embodiment, a crushing enclosure skirt 215 is protruding from the top of the crushing box 210. The crushing enclosure skirt 215 is arranged around the feeding port 204, so that the batteries to be crushed can be reliably fed into the feeding port 204 through the crushing enclosure skirt 215. The crushing assembly 240 includes a driving member 242, a first gear 244, a first crushing roller 246, a second gear 248 and a second crushing roller 249. The driving member 242 is installed on the crushing box 210. The first crushing roller 246 and the second crushing roller 249 are both rotatably connected to the crushing box 210. The first crushing roller 246 and the second crushing roller 249 are arranged opposite to each other at the feeding port 204. The power output end of the driving member 242 is connected to the first crushing roller 246. The first gear 244 is sleeved on the first crushing roller 246. The second gear 248 is sleeved on the second crushing roller 249. The second gear 248 meshes with the first gear 244. When the crushing assembly 240 crushes the battery, the driving member 242 drives the first crushing roller 246 to rotate and connect to the crushing box 210. The first crushing roller 246 drives the first gear 244 to rotate. Because the first gear 244 meshes with the second gear 248, the first gear 244 drives the second gear 248 to rotate, which in turn drives the second crushing roller 249 to rotate relative to the crushing box 210. In this way, the first crushing roller 246 and the second crushing roller 249 rotate in opposite directions, respectively, to achieve reliable battery crushing. It should be noted that the outer peripheral walls of the first crushing roller 246 and the second crushing roller 249 are both equipped with roller teeth (not shown) to ensure that the first crushing roller 246 and the second crushing roller 249 can crush the battery cells by rolling.

[0053] In one embodiment, the filter plate 220 is detachably connected to the crushing box 210 so that the filter plate 220 can be regularly disassembled for maintenance and cleaning to avoid the problem of the liquid holes 222 of the filter plate 220 being blocked and affecting the passage of electrolyte.

[0054] In one embodiment, an embedding groove is formed on the inner circumferential wall of the crushing chamber 202, and the vehicle-mounted crushing equipment 10 further includes a sealing ring, which is inserted into the embedding groove and is sleeved on the outer circumference of the filter plate 220, so that the outer circumference of the filter plate 220 is tightly connected to the inner circumferential wall of the crushing chamber 202.

[0055] In one embodiment, the inner circumferential wall of the crushing chamber 202 is provided with a plurality of supporting ribs along the circumferential direction. The plurality of supporting ribs jointly support and fix the filter plate 220 , so that the filter plate 220 is better connected to the inner circumferential wall of the crushing chamber 202 .

[0056] It should be noted that the sliding door assembly 230 can be opened or closed at the discharge port 206 manually or by a driving mechanism. In this embodiment, the sliding door assembly 230 is opened or closed at the discharge port 206 by a driving mechanism. As shown in FIG2 , in one embodiment, the sliding door assembly 230 includes a fixing frame 232, a driving cylinder 234, and a sliding door 236. The fixing frame 232 is fixed to the outer peripheral wall of the crushing box 210. The driving cylinder 234 is mounted on the fixing frame 232. The power output end of the driving cylinder 234 is connected to the sliding door 236. The side wall of the crushing box 210 is provided with a slide slot 216 that communicates with the discharge port 206. The sliding door 236 is located in the slide slot 216 and is slidably connected to the crushing box 210, so that the driving cylinder 234 drives the sliding door 236 to slide relative to the crushing box 210.

[0057] Compared with the related art, the present disclosure has the following advantages including but not limited to:

[0058] 1. The above-mentioned vehicle-mounted crushing device 10 senses the oxygen concentration in the crushing main chamber 2022 through the oxygen concentration sensor 2023. When the oxygen concentration sensor 2023 generates a sensing signal, the supply control valve 320 opens, allowing the nitrogen source to supply nitrogen to the crushing main chamber 2022 through the nitrogen pipe body 310. Otherwise, the supply control valve 320 closes, avoiding the problem of the nitrogen pipe body 310 continuously supplying nitrogen to the crushing main chamber 2022. In this way, the oxygen concentration in the crushing main chamber 2022 is always lower than the preset concentration threshold, avoiding the situation where the positive electrode material or SEI film decomposes and generates oxygen and burns during the battery crushing process, thereby improving the crushing safety of the battery.

[0059] 2. During the crushing process, the sliding door assembly 230 can always be closed at the discharge port 206, so that the oxygen concentration in the crushing main chamber 2022 is more accurate. At the same time, injecting nitrogen into the crushing main chamber 2022 during the crushing period can quickly and effectively reduce the oxygen concentration in the crushing main chamber 2022 and reduce the nitrogen consumption, thereby reducing the cost required for battery crushing and recycling.

[0060] 3. When the crushing is completed, the gas in the crushing main chamber 2022 and the evaporation chamber 2024 can be extracted through the exhaust gas treatment mechanism 400 to ensure the safety of the subsequent opening of the sliding door assembly 230 at the discharge port 206; after the sliding door assembly 230 is opened at the discharge port 206, the crushed waste can be discharged through the discharge port 206, thereby improving the safety of the vehicle-mounted crushing equipment 10.

[0061] 4. The exhaust gas treatment mechanism 400 can buffer and treat the exhaust gas to avoid the problem of exhaust gas being directly discharged and polluting the environment.

[0062] 5. Since the filter plate 220 is provided with a plurality of spaced-apart liquid holes 222, the electrolyte in the crushed waste flows into the evaporation chamber 2024 through the filter holes, thereby reliably separating the crushed waste from the electrolyte, avoiding the problem of the crushed waste being mixed with a large amount of electrolyte, and improving the initial separation effect of the electrolyte in the crushed waste.

[0063] 6. A heating module 2025 is provided on the inner bottom wall of the evaporation chamber 2024, so that the heating module 2025 heats and evaporates the electrolyte in the evaporation chamber 2024, thereby improving the efficiency of electrolyte evaporation, avoiding the problem of accidental risks caused by long-term retention of electrolyte in the evaporation chamber 2024, and further improving the safety of the vehicle-mounted crushing equipment 10.

[0064] 7. The pushing mechanism 500 is used to push the crushed material on the filter plate 220 out through the discharge port 206 after the sliding door assembly 230 is opened at the discharge port 206. No manual intervention is required, which makes it easy to automatically discharge the crushed material and improves the discharge efficiency of the crushed material.

[0065] 8. The powder in the crushed material first passes through the multiple screening holes 612 and falls into the powder trough 624 during the process of the crushed material being discharged along the discharge guide plate 610. In this way, the powder in the crushed material is pre-separated from other substances during the discharge, thereby improving the efficiency of battery crushing and recycling.

[0066] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-mentioned embodiments only express several implementation methods of the present disclosure. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present disclosure, several variations and improvements can be made, which all fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the patent of the present disclosure shall be based on the attached claims.
