[0017] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme will be described clearly and completely below in combination with the drawings and embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

In this process, the nitrogen making part continuously fills nitrogen into the buffer bin 2, the cavity of the shredder 3, the discharge bin 4 and the Z-type elevator 5, so as to ensure that the oxygen concentration is lower than 3%; at the same time, the air in the buffer bin 2, the shredder 3, the discharge bin 4 and the Z-type elevator 5 is continuously sucked into the environmental protection treatment part.

[0025] Among them: the shredder 3 is provided with a temperature and pressure detector, an oxygen content detector and a explosion venting device.

[0026] The shredder 3 controls the atmosphere inside the equipment through a temperature pressure detector and an oxygen content detector: during the shredding process, the shredder 3 detects the oxygen concentration, temperature and pressure inside the shredding cavity in real time through the oxygen content detector and the temperature pressure detector, so as to ensure that the oxygen concentration is lower than 3% and the temperature and pressure are appropriate; when the oxygen concentration, temperature and pressure exceed the set safety value, the shredder stops working and continuously charges nitrogen into the shredder cavity until the oxygen and temperature are reduced to the safety range, and then the shredding is performed again. When the gas pressure in the shredder 3 is high and there is a risk of combustion explosion, the high-pressure gas is discharged through the explosion venting device to ensure safety.

[0027] Embodiment 3

[0028] From Figure 1 , Figure 2 It can be known that the vehicle-mounted lithium battery crushing and recycling equipment has the following advantages: the drying part comprises a rake dryer 6 and a discharge screw conveyor 7; the feed inlet of the rake dryer 6 is communicated with the discharge outlet of the Z-type elevator 5 through a plug valve, and the discharge outlet of the rake dryer 6 is communicated with the feed inlet of the discharge screw conveyor 7 through a plug valve; the rake dryer 6 is connected with the nitrogen making part through an air inlet pipeline and connected with the environmental protection treatment part through an air outlet pipeline.

[0029] The drying part is used for volatilizing electrolyte in the battery waste: the Z-type elevator 5 lifts the battery waste to the rake dryer 6; at this time, the valve at the upper part of the rake dryer 6 is opened, and the valve at the lower part is closed; when a certain amount of battery waste is stored in the rake dryer 6, the feed valve is closed, the rake dryer starts to pass in heated oil to heat and control the temperature at 150-200 DEG C, the rake rotation makes the battery waste uniformly heated, the electrolyte contained in the battery waste is rapidly volatilized and passed into the environmental protection treatment part; the discharge outlet of the rake dryer is opened, the rake pushes the dried battery waste into the discharge screw conveyor, and the discharge screw conveyor conveys the battery waste to the ton cloth bag located at the lower part.

[0032] Embodiment 4

[0033] From Figure 1 , Figure 2 It can be known that the vehicle-mounted lithium battery crushing and recycling equipment has the following advantages: the environmental protection treatment component includes a cyclone dust collector 8, a To combustion furnace 9, a quenching tower 10, an alkali spraying tower 11, a water spraying tower 12, an activated carbon adsorption box 13 and a fan 14; the cyclone dust collector 8, the To combustion furnace 9, the quenching tower 10, the alkali spraying tower 11, the water spraying tower 12, the activated carbon adsorption box 13 and the fan 14 are sequentially connected; the tail gas exhaust pipelines of the respective branches of the buffer bin 2, the shredder 3, the discharge bin 4, the Z-shaped elevator 5 and the rake dryer 6 are communicated with the air inlet of the cyclone dust collector 8 through a tail gas main pipeline.

[0034] The environmental protection treatment component is used for recycling the pollutants generated in the battery crushing process to realize standard discharge: the fan 14 generates negative pressure through impeller rotation, the waste gas gas replaced in the buffer bin 2, the shredding cavity of the shredder 3, the discharge bin 4, the Z-shaped elevator 5 and the rake dryer 6 is collected through the tail gas pipeline, then enters the cyclone dust collector 8 to remove the dust particles in the waste gas, then enters the To combustion furnace 9 to remove the organic waste in the waste gas through combustion, then enters the quenching tower 10 and then enters the alkali spraying tower 11 to remove the acidic substances generated through low-temperature cracking through neutralization reaction, then enters the water spraying tower 12 to remove the acid-base substances which are not completely neutralized in the alkali spraying, and finally the gas enters the activated carbon adsorption box 13 to remove the harmful substances which are not completely treated in the previous stage. When the previous equipment in the environmental protection treatment component fails or is not completely removed, the activated carbon adsorption box 13 can be used as a safety guarantee when the previous equipment fails.

[0035] The tail gas is treated from the beginning of the battery entering the buffer bin to the end of entering the rake dryer for heating and low-temperature volatilization in the whole process of crushing the lithium battery, so that the dust and the gas containing electrolyte cannot leak out, and the waste gas is discharged after being purified and removing the pollutants in the environmental protection treatment component. The residual substances in the cyclone dust collector 8 are regularly cleaned into a ton cloth bag.

[0036] Example 5

[0037] From Figure 1 , Figure 2 It can be known that the vehicle-mounted lithium battery crushing and recycling equipment has the following advantages: the vehicle-mounted lithium battery crushing and recycling equipment further comprises a heat tracing system 16, and the tail gas communication pipelines of the rake dryer 6 and the cyclone dust collector 8 are each provided with the heat tracing system 16.

[0038] The heat tracing system 16 prevents the electrolyte from being condensed and liquefied in the pipeline, so that the pollutants are better recycled.

[0039] Example 6

[0040] From Figure 1 , Figure 2It can be seen that the present invention provides a vehicle-mounted lithium battery crushing and recycling equipment: the nitrogen generating component includes an air compressor 17, a nitrogen generator 18, and a refrigerated dryer 19. The air compressor 17 and the refrigerated dryer 19 are both connected to the nitrogen generator 18. The nitrogen generator 18 is connected to the buffer bin 2, the shredder 3, the discharge bin 4, the Z-type elevator 5, and the rake dryer 6 respectively through a nitrogen output pipe.

[0041] The compressed air provided by the air compressor 17 is partly used by the gate valve and partly used to provide compressed air to the nitrogen generator 19; the nitrogen generator 19 provides sufficient nitrogen to the shredding and drying components to meet the required purity and flow rate.

[0042] like Figure 3 As shown, the working process of this utility model's vehicle-mounted lithium battery crushing and recycling equipment is as follows: 1. Manually open the small door of the protective cover and place the waste lithium batteries at the feeding end of the bucket elevator 1. After the bucket elevator 1 transports the waste lithium batteries to the top of the buffer bin 2, the upper valve of the buffer bin 2 opens, and the waste lithium batteries fall into the buffer bin 2. Then, the upper valve of the buffer bin 2 closes, forming a space. At this time, the lower valve of the buffer bin 2 opens, and the waste lithium batteries fall into the shredder 3 for crushing. The crushed lithium battery material falls into the rake dryer 6 through the discharge bin 4 and the Z-type elevator 5. 2. After storing a certain amount of battery waste in the rake dryer 6, heating oil is introduced to control the temperature at 150-200℃. The rotation of the rake ensures that the battery waste is heated evenly, quickly evaporating all the electrolyte contained in the battery waste and introducing it into the environmental protection treatment component. Then, the discharge port of the rake dryer opens, and the battery waste is pushed by the rake into the discharge screw conveyor and transported to the ton cloth bag located below it. Third, during the process of crushing lithium batteries and heating batteries, the environmental protection treatment component treats the pollutants in the exhaust gas generated in the two processes, ensuring that the exhaust gas meets the emission standards before being discharged. Among them, the buffer bin 2, shredder 3, discharge bin 4, Z-type elevator 5, and rake dryer 6 are continuously filled with nitrogen for protection, so that the oxygen content in each piece of equipment is kept at a low concentration (below about 3%) to avoid fire, combustion, and explosion.

[0043] The lithium battery recycling equipment has the following advantages: 1. The waste batteries are crushed and recycled through the electrified crushing component and the drying component; nitrogen gas is provided by the nitrogen production component to avoid combustion and explosion during the recycling process, thereby ensuring the safety of the recycling process; the tail gas during the recycling process is treated by the environmental protection treatment component to meet the environmental protection requirements; 2. The drying component enables the battery waste to be heated and dried in the dryer, and the electrolyte is completely volatilized, and the general solid waste enters the ton bag, thereby realizing complete crushing and recycling of the battery; 3. The electrified crushing component, the drying component, the nitrogen production component and the environmental protection treatment component reasonably utilize the space, and the overall space is compact and integrated with the pry-mounted chassis, the pry-mounted chassis is directly installed and fixed on the skeleton trailer, and the vehicle-mounted mobile is realized through the towing equipment, thereby solving the problem of recycling waste lithium batteries in various regional manufacturers.

[0044] In summary, the vehicle-mounted lithium battery crushing and recycling equipment can be moved to lithium battery manufacturers and related product application manufacturers, and the collected waste lithium batteries are safely crushed and recycled on site, thereby solving the urgent problem of recycling waste lithium batteries in various regional manufacturers, and the waste lithium batteries no longer need to be transported to a special assembly line for processing.
