Description

Technical Field

[0001] The present invention relates to the field of crushing technology, and more specifically, to a crushing processing device for recycling new energy vehicle batteries. Background Art

[0002] With the vigorous development of the new energy vehicle industry, the demand for power lithium batteries as its core components has increased dramatically. However, the service life of power lithium batteries is limited. Against this background, battery recycling crushing and processing equipment came into being, using powerful mechanical cutters to perform preliminary crushing of waste lithium batteries and decompose the battery shell and internal materials.

[0003] Existing crushing processing devices are mostly composed of a crushing kettle, a gas converter and a crushing roller, and their working principle is as follows: first, the battery to be crushed is placed inside the crushing kettle, and then the inside of the crushing kettle is isolated from the outside world, and the internal oxygen of the crushing kettle is discharged through the gas converter, and nitrogen is released into the interior of the crushing kettle. Then, the crushing roller is started. When the crushing roller rotates, the battery will be crushed, and the oxygen is converted into nitrogen to reduce the humidity inside the crushing kettle, isolate moisture, prevent conductivity and arcing when the battery is crushed, and reduce the risk of fire or explosion. Finally, when the battery crushing is completed, the crushed batteries are uniformly discharged from the interior of the crushing kettle to complete the battery crushing work.

[0004] In order to prevent safety hazards caused by conductivity or arcing, the current technical path generally adopts the strategy of first converting the crushing environment from oxygen to nitrogen and then performing the crushing operation. Although this method can effectively improve the safety of operations, the implementation of the oxygen-to-nitrogen process requires the support of professional equipment. This undoubtedly increases the operating cost burden for processing units with limited resources and small scale, and limits the wide applicability of the technology. In addition, from the perspective of the operating process, before the crushing operation, it is necessary to wait for the oxygen-to-nitrogen conversion process to be completed inside the crushing kettle. This step not only prolongs the overall operation cycle, but also directly leads to a decrease in work efficiency. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 - Figure 6 As shown, a crushing and processing device for recycling new energy vehicle batteries includes a crushing kettle 1, a mounting frame 2 is fixedly connected to the outer side of the crushing kettle 1, a pair of crushing rollers 3 are installed inside the crushing kettle 1, and both ends of the pair of crushing rollers 3 pass through the crushing kettle 1, and the outer sides of the pair of crushing rollers 3 are fixedly connected to meshing spur gears 63, and also include:

[0033] A liquid outlet pipe 4, the liquid outlet pipe 4 is fixedly connected to the inside of the crushing kettle 1, one end of the liquid outlet pipe 4 passes through the crushing kettle 1, a water stop plate 5 is slidably connected to the inside of the liquid outlet pipe 4, and a supporting mechanism is arranged on the periphery of the water stop plate 5, the supporting mechanism includes a water stop box 6, and the supporting mechanism is used to support and reset the water stop plate 5;

[0034] An air transfer tube 7, a pair of air transfer tubes 7 are provided, and the pair of air transfer tubes 7 are fixedly connected to the inside of the water stop box 6, and one end of the pair of air transfer tubes 7 away from the water stop box 6 is fixedly connected to an air pressure tube 8, and the air pressure tube 8 is fixedly connected to the outside of the crushing kettle 1, and a one-way valve is installed on the outside of the pair of air pressure tubes 8, and one end of the crushing roller 3 close to the spur gear 63 is fixedly connected to a connecting rod 9, and a compression mechanism for compressing the air inside the air pressure tube 8 is provided on the periphery of the connecting rod 9.

[0035] In order to prevent safety hazards caused by electrical conduction or arcing, the current technical path generally adopts the strategy of first converting the crushing environment from oxygen to nitrogen and then performing the crushing operation. Although this method can effectively improve the safety of the operation, the implementation of the oxygen-to-nitrogen conversion process requires the support of professional equipment, which undoubtedly increases the operating cost burden for processing units with limited resources and small scale, and limits the wide applicability of the technology. In addition, from the perspective of the operation process, before the crushing operation, it is necessary to wait for the conversion process of oxygen to nitrogen to be completed inside the crushing kettle 1. This step not only prolongs the overall operation cycle, but also directly leads to a decrease in work efficiency. When the embodiment of the present invention is used, the liquid outlet pipe 4 is firstly connected to the outlet pipe 4. One end of the crushing kettle 1 is connected to an external water pipe, and the external water pipe discharges an inert liquid. The specific inert liquid depends on the actual situation. Then the crushing roller 3 is started, and the battery to be crushed is directly poured into the crushing kettle 1 through the top. At this time, a pair of crushing rollers 3 rotate in opposite directions under the action of the spur gear 63, so as to crush the battery. Moreover, when the crushing rollers 3 rotate, the crushing rollers 3 will also drive the connecting rod 9 to rotate. The rotation of the connecting rod 9 drives the compression mechanism to operate. When the compression mechanism is running, it will reciprocate and compress the internal air of a pair of air pressure tubes 8, and the one-way valve on the outside of the air pressure tube 8 can ensure that the external air enters the interior of the air pressure tube 8. , but cannot be discharged through the one-way valve. When the internal air pressure of the air pressure tube 8 increases, the air pressure will be transmitted to the inside of the water stop box 6 through the air transmission tube 7. At this time, the supporting mechanism inside the water stop box 6 moves due to the air pressure, thereby driving the water stop plate 5 to move upward. At this time, the internal barrier of the water stop plate 5 to the liquid outlet pipe 4 is completed, and the external inert liquid can drip into the inside of the crushing kettle 1 along the liquid outlet pipe 4. At this time, when the crushing roller 3 crushes the battery, the inert gas sprayed from the liquid outlet pipe 4 can increase the flash point and volatility point of the electrolyte and organic solvent, reduce the risk of fire, and inhibit the migration of lithium ions from the negative electrode to the positive electrode, thereby preventing the occurrence of discharge heating effect. Through the above-mentioned structural design The design not only realizes the spraying of inert liquid to isolate the generation of electric arc, but also can realize the function of automatic spraying of inert liquid by the liquid outlet pipe 4 when the crushing roller 3 is started. Compared with the method of converting oxygen to nitrogen to isolate the electric arc, the present invention saves more cost and time by automatically spraying inert liquid, and is more suitable for small-scale crushing. Finally, when the crushing roller 3 stops running, it means that the crushing is completed, and the crushing roller 3 stops automatically driving the connecting rod 9 to stop rotating, and the stationary connecting rod 9 will drive the compression mechanism to stop running. At this time, the supporting mechanism will drive the water stop plate 5 to move down and reset, and block the inside of the liquid outlet pipe 4 again, avoiding the continued flow of the inert liquid, and improving the degree of automation of the device.

[0036] like Figure 3 , Figure 4 and Figure 5As shown, the compression mechanism includes an inclined plate 10, a pair of guide plates 11, a pair of baffle rods 12, a limiting rod 13, a connecting plate 14, a piston rod 15 and a piston plate 16. The inclined plate 10 is fixedly connected to the outer side of the connecting rod 9. The pair of guide plates 11 are respectively arranged on both sides of the inclined plate 10. The pair of baffle rods 12 are respectively fixedly connected to the side close to the pair of guide plates 11. The inclined plate 10 is arranged between the pair of baffle rods 12. The limiting rods 13 are respectively slidably connected to the inside of the pair of guide plates 11. The connecting plates 14 are respectively fixedly connected to one end of the pair of limiting rods 13 close to the crushing kettle 1. The connecting plate 14 is fixedly connected to the top of the mounting frame 2. The piston rod 15 is respectively fixedly connected to the top of the pair of guide plates 11. The piston plate 16 is fixedly connected to one end of the piston rod 15 away from the guide plate 11. The piston plate 16 is arranged inside the air pressure tube 8 and is adapted to the size of the inner wall of the air pressure tube 8.

[0037] When the connecting rod 9 rotates, it will drive the inclined plate 10 to rotate, and when the inclined plate 10 rotates, it will squeeze the baffle rods 12 on both sides. When the baffle rods 12 on both sides move under the squeezing force, they will synchronously drive the guide plates 11 to move, and the pair of guide plates 11 will move in opposite directions when moving. At this time, when one group of guide plates 11 drives the piston plate 16 to squeeze the internal air pressure of the air pressure tube 8 through the piston rod 15, the interior of the other group of air pressure tubes 8 is in a state of exhausting air through the one-way valve. At this time, the compressed air inside the air pressure tube 8 will enter the interior of the air transfer tube 7, and then enter the interior of the water stop box 6 through the air transfer tube 7, thereby driving the support mechanism to operate. When the pair of guide plates 11 move in different directions, it can be ensured that when the compression mechanism is running, the interior of the water stop box 6 is affected by the pair of air transfer tubes 7 and is always in an inflated state, while the support mechanism is always in an operating state, thereby ensuring that the water stop plate 5 is continuously opened and the flow of liquid in the liquid outlet pipe 4 is ensured.

[0038] like Figure 6 As shown, the supporting mechanism also includes a square plate 48, a pair of guide rods 17 and a compression spring 18. The square plate 48 is fixedly connected to one end of the water stop plate 5 away from the liquid outlet pipe 4. The two ends of the pair of guide rods 17 are respectively fixedly connected to the liquid outlet pipe 4 and the inner wall of the water stop box 6. The pair of guide rods 17 both pass through the square plate 48. The compression springs 18 are respectively mounted on the outside of the pair of guide rods 17.

[0039] When the internal air of a group of air transfer tubes 7 enters the interior of the water stop box 6, the air pressure inside the water stop box 6 below the square plate 48 increases, and the square plate 48 is affected by the air pressure and moves upward. The upward movement of the square plate 48 will drive the water stop plate 5 to move, thereby ending the blockage of the liquid outlet pipe 4, and when the square plate 48 moves upward, it will also squeeze the compression spring 18, causing the compression spring 18 to deform and generate elastic potential energy. When a pair of air transfer tubes 7 finish inflating the interior of the water stop box 6, the squeezing force on the compression spring 18 ends, and the elastic potential energy is released, driving the water stop plate 5 to move down and reset through the square plate 48, thereby blocking the interior of the liquid outlet pipe 4 again.

[0040] like Figure 7 and Figure 8 As shown, a baffle 19 is slidably connected to the inner wall of the crushing kettle 1, and both ends of the baffle 19 pass through the crushing kettle 1, a first bevel gear 20 is fixedly connected to the outer side of the crushing roller 3, a second bevel gear 21 is meshed on one side of the first bevel gear 20, a transmission rod 22 is fixedly connected inside the second bevel gear 21, a pair of limit rings 23 are rotatably connected to the outer side of the transmission rod 22, the pair of limit rings 23 are fixedly connected to the top of the mounting frame 2, a first sprocket 24 is fixedly connected to the outer side of the transmission rod 22, a second sprocket 25 is arranged on the periphery of the first sprocket 24, a chain 26 is meshed on the outer sides of the first sprocket 24 and the second sprocket 25, and a reciprocating mechanism for driving the baffle 19 to reciprocate is arranged inside the second sprocket 25.

[0041] When the crushing roller 3 is in operation, it will drive the first bevel gear 20 to rotate. The rotation of the first bevel gear 20 will drive the first sprocket 24 to rotate through the transmission rod 22. The rotation of the first sprocket 24 will drive the second sprocket 25 to rotate through the chain 26. When the second sprocket 25 rotates, it will drive the reciprocating mechanism to operate. At this time, the reciprocating mechanism will drive the baffle 19 to reciprocate inside the crushing kettle 1. During the reciprocating movement of the baffle 19, it can hit the inert liquid sprayed by the liquid outlet pipe 4, and diffuse the inert liquid to different positions inside the crushing kettle 1, so that the inert liquid can better dilute the organic gas concentration in the crushing kettle 1 to prevent explosion caused by excessive gas concentration. In addition, during the reciprocating movement of the baffle 19, the baffle 19 can also hit the battery that is in the state of falling into the crushing kettle 1, and initially break up the batteries that are stuck together, which is beneficial to subsequent crushing operations.

[0042] like Figure 7 and Figure 8As shown, the reciprocating mechanism includes a forward and reverse screw rod 27, a slide groove, a pair of support plates 28, a threaded plate 29 and a slider. The end of the forward and reverse screw rod 27 close to the second sprocket 25 is fixedly connected to the inside of the second sprocket 25, and the pair of support plates 28 are rotatably connected to the outer side of the forward and reverse screw rod 27 and the end of the forward and reverse screw rod 27 away from the second sprocket 25 respectively. A slide groove is provided on the outer side of the forward and reverse screw rod 27, and the threaded plate 29 is sleeved on the outer side of the forward and reverse screw rod 27. The slider is fixed to the inside of the threaded plate 29, and the slider is threadedly connected to the slide groove. The end of the threaded plate 29 away from the forward and reverse screw rod 27 is fixed to the baffle 19.

[0043] When the second sprocket 25 rotates, it will drive the forward and reverse screw rods 27 to rotate. When the forward and reverse screw rods 27 rotate, they will drive the internal slider of the threaded plate 29 to move back and forth continuously through the threaded groove. The movement of the slider will drive the threaded plate 29 to move. Finally, the movement of the threaded plate 29 will drive the baffle 19 to move back and forth continuously.

[0044] like Fig. 9 and Fig.10 As shown, the reciprocating mechanism includes a forward and reverse screw rod 27, a slide groove, a pair of support plates 28, a threaded plate 29 and a slider. The end of the forward and reverse screw rod 27 close to the second sprocket 25 is fixedly connected to the inside of the second sprocket 25, and the pair of support plates 28 are rotatably connected to the outer side of the forward and reverse screw rod 27 and the end of the forward and reverse screw rod 27 away from the second sprocket 25 respectively. A slide groove is provided on the outer side of the forward and reverse screw rod 27, and the threaded plate 29 is sleeved on the outer side of the forward and reverse screw rod 27. The slider is fixed to the inside of the threaded plate 29, and the slider is threadedly connected to the slide groove. The end of the threaded plate 29 away from the forward and reverse screw rod 27 is fixed to the baffle 19.

[0045] When the baffle 19 hits the battery or the inert liquid, the outer side of the baffle 19 is easily attached with battery or inert liquid impurities. When the embodiment of the present invention is used, when the baffle 19 moves back and forth, when the baffle 19 moves toward the side of the traction rope 35 away from the fixed connection with the crushing kettle 1, due to the limited length of the traction rope 35, when the baffle 19 moves, the traction rope 35 will pull the scraper 31 to move downward along the limit groove 30, and the arrangement of the concave plate 32 can ensure that a pair of scrapers 31 move at the same time, and the scraper 31 moves to fit the outer side of the baffle 19. The scraper 31 performs "wall scraping" work on the side, thereby cleaning impurities on the outside of the baffle 19, and when the scraper 31 moves, it will also pull the tension spring 34, causing the tension spring 34 to deform and generate elastic potential energy. When the baffle 19 moves in the opposite direction, the pulling of the scraper 31 by the traction rope 35 will gradually end, and the tension spring 34 will gradually release the elastic potential energy, pulling the scraper 31 to reset, preparing for the next "wall scraping" work, and when the scraper 31 moves upward, the outside of the baffle 19 will be cleaned again.

[0046] like Fig.10 As shown, the reciprocating mechanism includes a forward and reverse screw rod 27, a slide groove, a pair of support plates 28, a threaded plate 29 and a slider. The end of the forward and reverse screw rod 27 close to the second sprocket 25 is fixedly connected to the inside of the second sprocket 25, and the pair of support plates 28 are rotatably connected to the outer side of the forward and reverse screw rod 27 and the end of the forward and reverse screw rod 27 away from the second sprocket 25 respectively. A slide groove is provided on the outer side of the forward and reverse screw rod 27, and the threaded plate 29 is sleeved on the outer side of the forward and reverse screw rod 27. The slider is fixed to the inside of the threaded plate 29, and the slider is threadedly connected to the slide groove. The end of the threaded plate 29 away from the forward and reverse screw rod 27 is fixed to the baffle 19.

[0047] The diverter plate 37 is triangular in shape, which can ensure that the batteries or the inert liquid will not accumulate on the top of the diverter plate 37 , but will fall into the crushing kettle 1 along the slope of the diverter plate 37 .

[0048] Working principle: First, connect the end of the liquid outlet pipe 4 away from the crushing kettle 1 to the external water pipe, and the external water pipe discharges an inert liquid. The specific inert liquid depends on the actual situation. Then start the crushing roller 3, and pour the battery to be crushed directly into the crushing kettle 1 through the top. At this time, a pair of crushing rollers 3 rotate in opposite directions under the action of the spur gear 63, so as to crush the battery. Moreover, when the crushing rollers 3 rotate, the crushing rollers 3 will also drive the connecting rod 9 to rotate. The rotation of the connecting rod 9 will drive the compression mechanism to operate. When the compression mechanism is running, it will reciprocately compress the internal air of a pair of air pressure tubes 8, and the one-way valve on the outside of the air pressure tube 8 can ensure that the external air enters the interior of the air pressure tube 8 and cannot be discharged through the one-way valve. When the internal air pressure of the air pressure tube 8 increases, the air pressure will be transmitted to the interior of the water stop box 6 through the air transmission tube 7. At this time , the supporting mechanism inside the water stop box 6 moves due to the air pressure, thereby driving the water stop plate 5 to move upward. At this time, the water stop plate 5 ends its internal barrier to the liquid outlet pipe 4, and the inert liquid from the outside can drip into the crushing kettle 1 along the liquid outlet pipe 4. At this time, when the crushing roller 3 crushes the battery, the inert gas sprayed by the liquid outlet pipe 4 can increase the flash point and volatility point of the electrolyte and organic solvent, reduce the risk of fire, and inhibit the migration of lithium ions from the negative electrode to the positive electrode, preventing the occurrence of discharge heating effect. Finally, when the crushing roller 3 stops running, it means that the crushing is completed, and the crushing roller 3 stops automatically driving the connecting rod 9 to stop rotating, and the stationary connecting rod 9 will drive the compression mechanism to stop running. At this time, the supporting mechanism will drive the water stop plate 5 to move down and reset, and block the inside of the liquid outlet pipe 4 again, avoiding the continued flow of the inert liquid, and improving the automation of the device.

[0049] When the connecting rod 9 rotates, it will drive the inclined plate 10 to rotate, and when the inclined plate 10 rotates, it will squeeze the baffle rods 12 on both sides. When the baffle rods 12 on both sides move under the squeezing force, they will synchronously drive the guide plates 11 to move, and the pair of guide plates 11 will move in opposite directions when moving. At this time, when one group of guide plates 11 drives the piston plate 16 to squeeze the internal air pressure of the air pressure tube 8 through the piston rod 15, the inside of the other group of air pressure tubes 8 is in a state of being evacuated through the one-way valve. At this time, the compressed air inside the air pressure tube 8 will enter the inside of the air transfer tube 7, and then enter the inside of the water stop box 6 through the air transfer tube 7, thereby driving the support mechanism to operate. When the pair of guide plates 11 move in different directions, it can be ensured that when the compression mechanism is in operation, the inside of the water stop box 6 is affected by the pair of air transfer tubes 7 and is always in an inflated state, while the support mechanism is always in an operating state, thereby ensuring that the water stop plate 5 is continuously opened and the flow of liquid in the liquid outlet pipe 4 is ensured.

[0050] When the internal air of a group of air transmission tubes 7 enters the interior of the water stop box 6, the air pressure inside the water stop box 6 below the square plate 48 increases, and the square plate 48 is affected by the air pressure and moves upward, and the upward movement of the square plate 48 drives the water stop plate 5 to move, thereby ending the blocking of the liquid outlet pipe 4, and when the square plate 48 moves upward, it also squeezes the compression spring 18, causing the compression spring 18 to deform and generate elastic potential energy. When the pair of air transmission tubes 7 finish inflating the interior of the water stop box 6, the squeezing force on the compression spring 18 ends, and the elastic potential energy is released, and the water stop plate 5 is driven to move downward and reset through the square plate 48, thereby blocking the interior of the liquid outlet pipe 4 again.

[0051] When the crushing roller 3 is in operation, it drives the first bevel gear 20 to rotate. The rotation of the first bevel gear 20 drives the first sprocket 24 to rotate through the transmission rod 22. The rotation of the first sprocket 24 drives the second sprocket 25 to rotate through the chain 26. When the second sprocket 25 rotates, the second sprocket 25 drives the positive and negative threaded rod 27 to rotate. When the positive and negative threaded rod 27 rotates, it drives the internal slider of the threaded plate 29 to move back and forth continuously through the thread groove. The movement of the slider drives the threaded plate 29 to move. Finally, the threaded plate 29 moves. The baffle 19 will be driven to continuously reciprocate. During the reciprocating movement of the baffle 19, it can hit the inert liquid sprayed by the liquid outlet pipe 4, diffuse the inert liquid to different positions inside the crushing kettle 1, so that the inert liquid can better dilute the organic gas concentration in the crushing kettle 1, and prevent explosion caused by excessive gas concentration. In addition, during the reciprocating movement of the baffle 19, the baffle 19 can also hit the battery that is in the state of falling into the crushing kettle 1, and initially break up the batteries that are stuck together, which is beneficial to the subsequent crushing operation.

[0052] When the baffle 19 moves back and forth, when the baffle 19 moves toward the side of the traction rope 35 away from the fixed connection with the crushing kettle 1, due to the limited length of the traction rope 35, when the baffle 19 moves, the traction rope 35 will pull the scraper 31 to move downward along the limit groove 30, and the setting of the concave plate 32 can ensure that a pair of scrapers 31 move at the same time, and the movement of the scraper 31 will fit the outer side of the baffle 19 to perform "wall scraping" work, thereby cleaning the impurities on the outer side of the baffle 19, and when the scraper 31 moves, it will also pull the tension spring 34, causing the tension spring 34 to deform and generate elastic potential energy. When the baffle 19 moves in the opposite direction, the pulling of the scraper 31 by the traction rope 35 will gradually end, and the tension spring 34 will gradually release the elastic potential energy, pulling the scraper 31 to reset, preparing for the next "wall scraping" work, and during the upward movement of the scraper 31, the outer side of the baffle 19 will be cleaned again.

[0053] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
