Description

Technical Field

[0001] This invention relates to the field of lithium battery recycling, and in particular to an environmentally friendly crusher for recycling waste lithium batteries. Background Technology

[0002] With the rapid development of new energy vehicles and electronic devices, the demand for lithium batteries is increasing rapidly. However, batteries have a limited lifespan, and with the application of lithium batteries, the problem of recycling and disposing of a large number of waste lithium batteries has also emerged.

[0003] Currently, the open crushing method is mostly used in the crushing and recycling of lithium batteries. That is, the lithium batteries are directly fed into the open crusher. During the crushing process, the electrolyte is prone to leakage due to mechanical impact or high temperature, and it is difficult to collect. This causes the electrolyte to come into contact with the air in the open environment and undergo oxidation reaction, producing harmful gases or even explosions. The harmful gases generated during crushing are directly emitted, and the electrolyte is easily exposed to the air and undergoes oxidation reaction, which easily pollutes the environment and has poor environmental protection.

[0004] Currently, the lithium battery crushing process involves directly feeding the entire lithium battery into the crusher, resulting in a mixture of components such as electrode sheets, tabs, cores, and casings. This makes subsequent sorting difficult, leading to low efficiency in the recovery of metals and resources. Furthermore, the electrolyte is not collected separately, and the inert gas protection is insufficient, causing the active materials to degrade and affecting the recycling value.

[0005] Therefore, it is necessary to design an environmentally friendly crusher for recycling waste lithium batteries to solve the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of poor environmental protection and low recycling efficiency in the current crushing and recycling of lithium batteries, the purpose of this invention is to provide an environmentally friendly crusher for recycling waste lithium batteries that ensures environmental protection during the crushing process and improves recycling efficiency and resource recovery rate.

They are used to fill the sealed chamber 4 with cryogenic nitrogen and to isolate and expel oxygen and harmful gases generated during lithium battery crushing. This creates an inert gas environment within the sealed chamber 4, preventing oxidation of leaked electrolyte during crushing and reducing the risk of explosion. Three guide chambers 3 extend through the mounting plate 1 into the sealed chamber 4. A pusher frame 5 is fixedly connected to the right side of the bottom plate inside the sealed chamber 4.

The cutting frame 7 has a structure with a horizontal rectangular opening in the middle. The right side of the cutting frame 7 is fixedly connected to the left side of the pusher frame 5. Both the left and right side walls of the cutting frame 7 have a material passage hole structure. The material passage hole structure of the cutting frame 7 is at the same level as the upper side of the pusher frame 5. The columnar batteries that fall from the temporary storage chamber 6 onto the upper side of the pusher frame 5 can enter it through the material passage hole structure on the right side of the cutting frame 7.A processing rack 8 is fixedly connected to the left side of the bottom plate inside the enclosed chamber 4. The processing rack 8 is a six-sided open frame structure. The right side of the processing rack 8 is fixedly connected to the left side of the cutting rack 7. The interior of the frame structure of the processing rack 8 is interconnected with the left side material passage structure of the cutting rack 7 and is on the same horizontal plane. After being cut, the lithium battery entering the cutting rack 7 can enter the interior of the processing rack 8 through its left side material passage structure. The left side of the frame structure of the processing rack 8 has a chamfer structure sloping downward to the left. The open structure on the left side of the processing rack 8 is connected to the upper side of the guide hopper 3, which is connected to the crusher unit 2 located on the left side. The processing rack 8 is fixedly connected and interconnected. Its open front structure is fixedly connected and interconnected with the upper side of the guide hopper 3 connected to the crusher unit 2 located at the front. The processing rack 8 has a structure with a raised plate on its upper side. A pre-storage device 9 is provided at the upper right opening of the enclosed chamber 4. The pre-storage device 9 seals the upper right opening of the enclosed chamber 4 from the outside. The pre-storage device 9 is connected and interconnected with the temporary storage chamber 6. The pre-storage device 9 is used to place cylindrical lithium batteries and supply lithium batteries to the temporary storage chamber 6. The pre-storage device 9 can be controlled to open and close its gas connection with the outside and the enclosed chamber 4. The gas inside the device is replaced to allow the gas in the pre-storage device 9 to be discharged in an isolated manner and then filled with low-temperature nitrogen. Discharge devices 10 are located on the lower front, left, and middle sides of the mounting plate 1. All three discharge devices 10 are connected to the next-stage feed inlet of the lithium battery crushing and recycling line. The positions of the discharge devices 10 correspond to the three crushing units 2, and each discharge device 10 is fixedly connected to the lower discharge port of the corresponding crushing unit 2. The discharge devices 10 are used to collect lithium battery debris after crushing by the three crushing units 2 in an isolated manner, preventing the residue of harmful gases generated after lithium battery crushing. Discharge device 10 can be controlled to open and close its connection with the outside gas and exchange its own internal gas, so that the gas in discharge device 10 is discharged in isolation and filled with inert protective gas. After the gas exchange in discharge device 10 is completed, lithium battery crushed residue can be discharged. Positioning device 11 is provided on the lower side of temporary storage chamber 6 and the lower side of push frame 5. Positioning device 11 on the lower side of temporary storage chamber 6 is used to support and release the vertically arranged columnar lithium batteries inside. Positioning device 11 on the lower side of push frame 5 is used to position the columnar lithium batteries falling from temporary storage chamber 6.A propulsion device 12 is located at the lower center of the propulsion frame 5. The propulsion device 12 passes through the middle horizontal rectangular opening structure of the propulsion frame 5. The propulsion device 12 can operate at the middle horizontal rectangular opening structure of the propulsion frame 5 and the cutting frame 7. The propulsion device 12 is used to push the columnar lithium battery falling on the upper side of the propulsion frame 5 to the left, so that the columnar lithium battery moves to the left through the propulsion frame 5 and its upper side guide plate structure and enters the cutting frame 7. After the columnar lithium battery is processed in the cutting frame 7, it is pushed into the processing frame 8. After that, the propulsion device 12 is reset. A cutting device 13 is located on the upper side of the cutting frame 7. The cutting device 13 is used to cut the two ends of the columnar lithium battery that has entered the cutting frame 7, so that the front and rear electrodes of the columnar lithium battery are cut off. The two plates and two internal tabs of the battery are cut, separating the two plates and two tabs from the cylindrical lithium battery. The cut and separated plates and tabs fall into the guide hopper 3 connected to the crusher unit 2 in the middle, and then fall from the guide hopper 3 into the crusher unit 2 for crushing. The crushed plate residue and tab residue fall into the discharge device 10 connected to the crusher unit 2. At this time, the outer steel tube and the inner core of the cylindrical lithium battery are still in the cutting frame 7 until the cylindrical lithium battery at both ends is pushed into the processing frame 8 by the pushing device 12. A limiting device 14 is provided on the protruding plate structure on the upper side of the processing frame 8. The limiting device 14 is used to restrict the entry into the processing frame 8 by friction. The movement of the cylindrical lithium batteries at both ends of the cut ensures that the cylindrical lithium batteries in the processing rack 8 are moved only by the pushing device 12, so that the cylindrical lithium batteries in the processing rack 8 do not change their own position and remain in the final position after being pushed. The processing rack 8 is provided with a separation device 15 at the protruding plate structure. The separation device 15 is used to push out the core inside the cylindrical lithium batteries at both ends of the cut within the processing rack 8, so that the core inside the cylindrical lithium batteries at both ends of the cut are separated from the outer steel pipe. The core separated by the separation device 15 will be pushed forward to the guide hopper 3 connected to the front crushing unit 2, and will fall from the guide hopper 3 into the crushing unit 2 for crushing. The core slag after crushing will fall into The discharge device 10 connected to the crusher unit 2 then controls the separation device 15 to reset and remove the steel pipe structure of the cylindrical lithium battery. At this time, the outer steel pipe of the cylindrical lithium battery is still in the processing rack 8 until the propulsion device 12 pushes the next batch of cylindrical lithium batteries with both ends cut into the processing rack 8. The cylindrical lithium battery with only the steel pipe remaining will be pushed to the left by the next batch of cylindrical lithium batteries with both ends cut, and will be removed through the chamfered structure on the left side of the processing rack 8. It will fall into the guide hopper 3 connected to the crusher unit 2 on the left side, and then fall from the guide hopper 3 into the crusher unit 2 for crushing. The crushed steel pipe slag will fall into the discharge device 10 connected to the crusher unit 2.

The positions of the three discharge chambers 101 correspond to the three crushing units 2, respectively. The upper openings of the discharge chambers 101 extend upwards and are fixedly connected to the lower discharge ports of the corresponding crushing units 2. Rectangular holes are opened at the top and bottom positions on both the front and rear sides of the three discharge chambers 101.

The arc-shaped support structure of the positioning frame 114 corresponds to the arc-shaped bottom support structure of the barrier frame 112. The third electric slide rail 111 is controlled to run in opposite directions, so that the barrier frames 112 move away from each other, thereby causing the barrier frames 112 to detach from supporting the columnar lithium battery in the temporary storage compartment 6. At this time, the columnar lithium battery in the temporary storage compartment 6 will fall.

A pressure plate 143 is fixedly connected between the lower sides of the movable parts of the two first movable pairs 141. The pressure plate 143 is located at the open structure on the upper side of the processing frame 8. The pressure plate 143 is used to press down the cylindrical lithium battery located inside the processing frame 8 that has been cut at both ends, so that the cylindrical lithium battery itself will not move.

[0045] like Figures 15-18 As shown, the separation device 15 includes an electric push rod 151, a second movable pair 152, and a push plate 153. The electric push rod 151 is installed in the middle of the protruding plate structure on the upper side of the processing frame 8. The electric push rod 151 is horizontally positioned, and the telescopic part of the electric push rod 151 extends to the rear. Multiple sets of second movable pairs 152 are fixedly connected to the open structure at the rear side of the processing frame 8. All second movable pairs 152 are horizontally positioned, and the spacing between the second movable pairs 152 is consistent with the spacing between the columnar lithium batteries in contact with each other. The moving parts of the second movable pairs 152 all face to the rear. The rear ends of the moving parts of the multiple sets of second movable pairs 152 are fixedly connected to the rear ends of the telescopic parts of the electric push rod 151. The front ends of the moving parts of the second movable pairs 152 are all fixedly connected to the push plate 153.

[0046] like Figures 15-17 As shown, it also includes a drainage device 16, which includes a sealing cover 161, a third gas guide pipe 162, a return chamber 163, and a liquid guide pipe 164. The drainage device 16 is located at the cutting frame 7. The drainage device 16 is used to further and quickly absorb the harmful gases generated during the cutting of the lithium battery electrodes, and to further separate the electrolyte leaked during the cutting of the lithium battery electrodes. There are two sealing covers 161, which are fixedly connected to the front and rear sides of the cutting frame 7, respectively. The third gas guide pipe is fixedly connected to the middle of each sealing cover 161. The air pipe 162 and the third air pipe 162 extend out of the sealed chamber 4 respectively. The third air pipe 162 is used to connect to the external air pump. The backflow chamber 163 is fixedly connected to the front and rear positions of the lower side of the cutting frame 7. The backflow chamber 163 has an opposite inclined structure and a structure with a filter screen on the upper inclined surface. The liquid guide pipe 164 is fixedly connected to the middle of the lower side of the cutting frame 7. The liquid guide pipe 164 is connected to the two backflow chambers 163 respectively. The liquid guide pipe 164 extends backward out of the sealed chamber 4 and is used to connect to the external vacuum pump.

[0047] Example 2, as Figures 1-18As shown, the installation method of the environmentally friendly crusher for recycling waste lithium batteries is as follows: The environmentally friendly crusher for recycling waste lithium batteries is assembled onto the base frame of the lithium battery crushing and recycling line via mounting plate 1; the external ventilation pipe structure of the enclosed chamber 4 is connected to an external air pump and a low-temperature nitrogen source; the first air guide pipe 94 at the pre-storage chamber 91 is connected to the external air pump and the low-temperature nitrogen source; the lower opening of the discharge chamber 101 in the middle position is connected to the lithium battery electrode tab processing area of ​​the lithium battery crushing and recycling line; the lower opening of the discharge chamber 101 at the front position is connected to the lower opening of the discharge chamber 101 in the middle position. The opening is connected to the lithium battery core processing area of ​​the lithium battery crushing and recycling line; the lower opening of the discharge hopper 101 on the left side is connected to the lithium battery steel pipe processing area of ​​the lithium battery crushing and recycling line; the second air guide pipe 104 at the three discharge hoppers 101 is connected to the external vacuum pump, low-temperature nitrogen source and inert protective gas source; the third air guide pipe 162 is connected to the external vacuum pump; the liquid guide pipe 164 is connected to the external vacuum pump; the power circuit, signal circuit and control circuit of the environmentally friendly crusher for recycling waste lithium batteries are connected to the outside.

[0048] The environmentally friendly shredder for recycling waste lithium batteries employs the following internal gas management method before operation: An externally connected air pump extracts oxygen-containing gas from the sealed chamber 4, and an externally connected low-temperature nitrogen source replaces the gas in the sealed chamber 4 with low-temperature nitrogen, maintaining an inert and low-temperature environment. Simultaneously, the external ventilation pipe structure of the sealed chamber 4 replenishes the low-temperature nitrogen concentration in a timely manner. This protects the lithium batteries from oxidation caused by leaked electrolyte during end-point cutting, and the low-temperature environment also reduces the activity of the lithium battery electrolyte, lowering the risk of explosion during end-point cutting. Furthermore, the external ventilation pipe structure of the sealed chamber 4 also helps prevent this. The ventilation pipe isolates the harmful gases generated during the cutting of both ends of the lithium battery to the outside environment in a harmful gas treatment process; at the same time, it controls the second electric slide rail 102 located on the upper side, so that the second electric slide rail 102 drives the second sealing plate 103 connected to it to open, so that the three sets of discharge chambers 101 are in a state of communication with the space inside the sealed chamber 4, and the second sealing plate 103 on the lower side of the discharge chamber 101 is kept closed, so that the lower side of the discharge chamber 101 is in a closed state with the outside environment and the lithium battery crushing and recycling line. In this way, when oxygen-containing gas is extracted and low-temperature nitrogen is input into the sealed chamber 4, the gas in the discharge chamber 101 can also be replaced simultaneously.

[0049] The process of crushing cylindrical lithium batteries using this environmentally friendly crusher for recycling waste lithium batteries is as follows: ① Control the operation of the first electric slide rail 92 on the upper side of the pre-storage device 9, so that the first sealing plates 93 on the upper side move away from each other, making the upper side of the pre-storage compartment 91 open and the lower side of the pre-storage compartment 91 closed by the lower first sealing plate 93. At this time, the cylindrical lithium batteries can be placed in the pre-storage compartment 91. The partitions in the pre-storage compartment 91 will arrange the cylindrical lithium batteries neatly. At this time, the lower first sealing plate 93 will support the cylindrical lithium batteries. After the pre-storage compartment 91 is full of cylindrical lithium batteries, control the upper first sealing plate 93 to close the upper side of the pre-storage compartment 91. The internal space of the pre-storage chamber 91 is sealed. At this time, an external air pump and a low-temperature nitrogen source can be used to expel oxygen-containing air from the pre-storage chamber 91 through the first air duct 94 and fill it with low-temperature nitrogen, creating an inert and low-temperature environment inside the pre-storage chamber 91. This cools the cylindrical lithium batteries placed inside the pre-storage chamber 91, reducing the activity of the electrolyte within the cylindrical lithium batteries. Secondly, the operation of the first electric slide rail 92 on the lower side of the pre-storage device 9 is controlled, causing the lower first sealing plates 93 to move away from each other, leaving the lower side of the pre-storage chamber 91 open and the upper side of the pre-storage chamber 91 sealed through the upper first sealing plate 93. At this time, the gas inside the pre-storage chamber 91... The gas has been replaced with low-temperature nitrogen to prevent oxygen-containing gases from contaminating the inert and low-temperature environment inside the sealed compartment 4 when the pre-storage compartment 91 is storing cylindrical lithium batteries. After the first sealing plate 93 on the lower side is opened, the cylindrical lithium batteries in the pre-storage compartment 91 will fall into the temporary storage compartment 6. The partition structure inside the temporary storage compartment 6 will keep the cylindrical lithium batteries neatly arranged. At this time, the barrier frame 112 at the temporary storage compartment 6 will support the neatly arranged cylindrical lithium batteries; ③ The moving parts of the control third electric slide rail 111 will drive the barrier frames 112 to move away from each other, so that the barrier frames 112 no longer support the cylindrical lithium batteries in the temporary storage compartment 6. At this time, the bottom row of cylindrical lithium batteries in the temporary storage compartment 6 The battery will fall onto the upper side of the pusher 5. The bottom row of columnar lithium batteries will be positioned at the positioning frame 114 to prevent displacement of the columnar lithium batteries on the upper side of the pusher 5. Then, the moving part of the third electric slide rail 111 is controlled to drive the blocking frame 112 to move closer to each other, so that the blocking frame 112 supports the bottom row of columnar lithium batteries in the temporary storage compartment 6, preventing the columnar lithium batteries in the temporary storage compartment 6 from falling further. After that, the moving part of the fourth electric slide rail 113 can be controlled to drive the positioning frame 114 to move downward, so that the positioning frame 114 moves downward to disengage from contact and support of the columnar lithium batteries on the upper side of the pusher 5.④ Controlling the moving part of the fifth electric slide rail 121 drives the push block 122 to move to the left, causing the push block 122 to push a row of cylindrical lithium batteries located at the push frame 5 to move to the left. This row of cylindrical lithium batteries moves to the left at the push frame 5 through the guide plate structure on its upper side. The push block 122 will push the row of cylindrical lithium batteries into the cutting frame 7 until the leftmost one of the cylindrical lithium batteries in the row contacts the cutting blade 132. The push block 122 continues to move to the left, causing the row of cylindrical lithium batteries to contact each other; ⑤ Then, the dual-axis motor 131 is turned on to make the cutting blade 132 rotate counterclockwise at high speed, and the push block 122 continues to move to the left, causing the push block 122 to push the row of cylindrical lithium batteries to the left through the high... The rapidly rotating cutting blade 132 cuts the two electrodes of the row of cylindrical lithium batteries sequentially from left to right, causing the two end electrodes of the cylindrical lithium batteries to detach from the steel tubes of the cylindrical lithium batteries, and separating the electrode tabs of the cylindrical lithium batteries from their internal cores. As the row of cylindrical lithium batteries passes through the cutting blade 132, the cut end electrodes and electrode tabs will fall from the front and rear sides of the cutting frame 7 into the guide hopper 3 in the middle position, and then into the crushing unit 2 located in the middle position. At this time, the crushing unit 2 can be opened to crush the electrode sheets and electrode tabs into slag. ⑥ After the row of cylindrical lithium batteries has been pushed to the left by the pusher block 122 through the cutting blade 132, the row of cylindrical lithium batteries will continue to be pushed. The push block 122 is pushed to the left into the processing rack 8 until the fifth electric slide rail 121 moves the push block 122 to its left end. At this point, the row of columnar lithium batteries is in the processing position within the processing rack 8. That is, each battery in the row of columnar lithium batteries corresponds to the position of each push plate 153. When the row of columnar lithium batteries enters the processing rack 8, the pressure plate 143 limits the row of columnar lithium batteries in the processing rack 8 through the first moving pair 141 and the elastic member 142, preventing the row of columnar lithium batteries from displacing itself within the processing rack 8. Afterward, the fifth electric slide rail 121 can be controlled to move the push block 122 to the right for reset. ⑦ Then, the electric push rod 151 can be controlled to run, making... The telescopic component of the electric push rod 151 drives the moving component of the second moving pair 152 and the pusher 153 to move forward, so that the pusher 153 and the moving component of the second moving pair 152 enter the interior of the row of columnar lithium batteries at both ends to be cut, so that the pusher 153 pushes the core inside the row of columnar lithium batteries forward, so that the steel tube of the columnar lithium battery at both ends to be cut is separated from the core. The core pushed forward by the pusher 153 will fall into the guide chamber 3 located at the front and into the crusher unit 2 located at the front. At this time, the crusher unit 2 can be opened to crush the core into slag. The steel tube of the row of columnar lithium batteries after being cut at both ends and separated from the core will remain in the processing rack 8.⑧ When the fifth electric slide rail 121 drives the push block 122 to move to the right and reset to the right side position of the push frame 5, if the fifth electric slide rail 121 is controlled to drive the positioning frame 114 to move upward, and operates in the order of ③-⑥ above, the next row of cylindrical lithium batteries with cut electrodes will move to the left and enter the processing frame 8. At this time, the cylindrical lithium batteries with cut electrodes that are pushed into the processing frame 8 will push the previous row of cylindrical lithium battery steel tubes with cut electrodes and separated cores to the left, so that the previous row of cylindrical lithium battery steel tubes with cut electrodes and separated cores will fall from the left side of the processing frame 8, and the cut electrodes and separated cores will be removed. The cylindrical lithium battery steel tubes will fall into the feed hopper 3 located on the left, and then into the crusher unit 2 located on the left. At this time, the crusher unit 2 can be turned on to crush the steel tubes into slag. ⑨ Thus, by operating in the sequence of ③-⑧ above, a row of cylindrical lithium batteries can be processed from feeding, cutting and separating the electrode tabs and crushing, separating and crushing the core, and feeding and crushing the steel tubes. The process can be automatically and automatically crushed in a streamlined manner, and the crushing process is carried out in a closed loop. Harmful gases will not be emitted into the environment, improving the environmental friendliness of the crushing process. Furthermore, before crushing, two cutting blades 132 are used to cut the cylindrical lithium battery at both ends, separating the two electrodes and tabs. This allows for individual crushing and collection of the electrodes and tabs. Because the electrodes and tabs differ from the outer steel tube and inner core in the lithium battery structure, this individual separation and collection method is more convenient for subsequent recycling, such as reducing subsequent screening steps. The pusher blade 153 also separates the lithium battery steel tube and core, enabling further processing of the lithium battery's steel tube and core. Separate crushing and collection are performed for lithium batteries. Due to the significant differences in the composition of the steel pipes and cores, separate separation and collection are more convenient for subsequent recycling, improving the recycling efficiency and resource recovery rate. In contrast, traditional lithium battery crushing methods, which involve directly feeding lithium batteries into the crusher in an open environment, can easily lead to battery explosions, electrolyte leaks, and harmful gas leaks. Furthermore, the mixed composition of different lithium battery components makes them difficult to screen, complicating subsequent recycling processes. This environmentally friendly crusher for waste lithium battery recycling ensures both the environmental friendliness of the crushing process and the efficiency of subsequent resource recovery.

[0050] The environmentally friendly crusher for recycling waste lithium batteries uses an environmentally friendly and harmless method for discharging columnar lithium battery slag: As described in steps ⑤, ⑦, and ⑧ above, in the process of crushing columnar lithium batteries using the environmentally friendly crusher for recycling waste lithium batteries, three crusher units 2 respectively crush the electrode tabs, cores, and steel pipes. The resulting lithium battery slag falls into the discharge hoppers 101 connected to the three crusher units 2 for separate collection. When the lithium battery slag in any discharge hopper 101 gradually accumulates to the height of the second laser sensor 105 within it, the second laser sensor 105 in that discharge hopper 101 will detect that the lithium battery slag is about to be discharged. When the discharge chamber 101 is full, the second electric slide rail 102 on the upper side of the discharge chamber 101 can be controlled by the program based on the detection data of the second laser sensor 105. This causes the second electric slide rail 102 to drive the connected second sealing plate 103 to close the upper space of the discharge chamber 101. At this time, the internal space of the discharge chamber 101 is in a closed state. The subsequently crushed lithium battery residue will fall into the extension of the upper opening structure of the discharge chamber 101 and be temporarily stored. When the internal space of the discharge chamber 101 is in a closed state, the harmful gases generated during the crushing of the lithium batteries can be isolated and extracted by an external air pump through the second air guide pipe 104 of the discharge chamber 101. In the process of handling harmful gases transported to the outside, inert protective gas is introduced into the enclosed space inside the discharge hopper 101 through the second gas guide pipe 104 until the harmful gases in the discharge hopper 101 are extracted. Then, the second electric slide rail 102 on the lower side of the discharge hopper 101 can be controlled to open the second sealing plate 103 connected to it, so that the space below the discharge hopper 101 is connected to the feeding area of ​​the lithium battery crushing and recycling line. This allows the lithium battery slag in the discharge hopper 101 to enter the next stage of the lithium battery crushing and recycling line. After the lithium battery slag in the discharge hopper 101 is discharged, the second electric slide rail 102 on the lower side of the discharge hopper 101 can be controlled to open the second sealing plate 103 connected to it. 2. The second sealing plate 103 connected to it is closed, so that the lower side of the discharge chamber 101 is closed and a closed space is formed again. Then, the gas that has entered the environment after the discharge can be extracted through the second air guide pipe 104 of the discharge chamber 101, and low temperature nitrogen is reintroduced into the discharge chamber 101. Then, the second electric slide rail 102 and the second sealing plate 103 on the upper side of the discharge chamber 101 are controlled to open, so that the lithium battery residue temporarily left at the upper opening structure of the discharge chamber 101 and the lithium battery residue generated after subsequent crushing can enter it. In this way, the harmful gases generated after the columnar lithium battery is crushed will not be dispersed into the external environment, thus improving the environmental protection of the environment.

[0051] The environmentally friendly crusher for recycling waste lithium batteries replenishes columnar lithium batteries as follows: When the first laser sensor 95 on the lower side of the pre-storage chamber 91 does not detect any object, that is, when the first laser sensor 95 in the pre-storage chamber 91 does not detect the presence of a battery, the columnar lithium batteries in the surface pre-storage chamber 91 are crushed. At this time, the environmentally friendly crusher for recycling waste lithium batteries crushes the remaining columnar lithium batteries in the temporary storage chamber 6. At this time, the first electric slide rail 92 on the lower side can be controlled to drive the first sealing plate 93 connected to it to close, so that the pre-storage chamber 91 is in a closed space. At this time, the low-temperature nitrogen gas in the pre-storage chamber 91 can be isolated and extracted through the first air guide pipe 94. The harmful gases that seep in are treated in the harmful gas treatment process, which puts the pre-storage chamber 91 into a vacuum state. Then, the first electric slide rail 92 on the upper side can be controlled to open the first sealing plate 93 connected to it. At this time, outside air enters the pre-storage chamber 91, thus preventing the harmful gases in the sealed chamber 4 from being discharged to the outside. Then, as described in "processes ① and ② of the process of crushing columnar lithium batteries by the environmentally friendly crusher for recycling waste lithium batteries", columnar lithium batteries can be added to the pre-storage chamber 91. In this way, when columnar lithium batteries are added to the pre-storage chamber 91, the harmful gases in the sealed chamber 4 are still guaranteed not to leak to the outside, and the environmental protection of the crushing of lithium batteries is also achieved.

[0052] This environmentally friendly crusher for recycling waste lithium batteries further improves environmental friendliness and recycling efficiency through a diversion device 16: An external vacuum pump and air pump can be activated, allowing the harmful gases generated during the bipolar cutting of the cylindrical lithium battery by the cutting blades 132 to be directly and quickly extracted by the third air pipe 162 and sent to an external harmful gas treatment facility for processing. This prevents the harmful gases generated during bipolar cutting from excessively dispersing into the enclosed chamber 4, reducing the frequency of gas exchange within the enclosed chamber 4, further reducing the resources and energy required for gas exchange, and thus further improving environmental friendliness. Furthermore, the electrolyte leaking from the cylindrical lithium battery after bipolar cutting flows into the return chamber 163 and is extracted to an external electrolyte storage area through the liquid guide pipe 164, allowing the electrolyte to separate from the electrodes and tabs, further improving subsequent recycling efficiency.
