Description

Technical Field

[0001] The invention relates to the technical field of new energy battery recycling, in particular to an automatic speed regulating crushing device for recycling waste new energy batteries. Background Art

[0002] In today's era of rapid technological development, new energy technologies are widely used, and various types of new energy batteries are mass-produced and used. As these batteries reach the end of their service life or are eliminated due to performance degradation, the number of waste new energy batteries has increased dramatically, becoming a problem that needs to be solved urgently. In the recycling process of waste new energy batteries, crushing is the key first step.

[0003] However, the existing waste battery recycling and crushing equipment is relatively simple in design and single in function. Its crushing speed is usually fixed and cannot be automatically adjusted according to the dynamic changes of the feed amount. On the one hand, it affects the energy utilization rate. On the other hand, when the feed amount is too much, incomplete crushing or overload may occur. In addition, the chemical composition inside the waste new energy battery is complex, and some electrolytes and other substances are corrosive and toxic. The current waste battery recycling and crushing equipment usually directly uses crushing tools to crush the waste batteries, such as "CN115350799A A waste battery crusher", "CN109012963A A The "waste battery crushing device" each discloses a method for crushing waste batteries, but this crushing method can easily lead to damage to the internal parts of the crushing equipment, thereby affecting the service life of the impact crushing equipment; finally, in order to ensure the crushing quality, most waste battery recycling and crushing equipment will be equipped with screens and other components, but the screen will show aperture wear and cracking after long-term use. If the staff finds that there is a problem with the screen during the operation of the crushing equipment, the screen can usually only be replaced after the machine is shut down. This operation method is not only not conducive to the continuity of production, but also causes a huge waste of manpower and time. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic speed regulating crushing device for recycling waste new energy batteries to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic speed-regulating crushing device for recycling waste new energy batteries, the crushing device comprising a base, a crushing box, a crushing motor and a feed box, the crushing box is arranged above the base, the feed box is arranged above the crushing box, a crushing chamber is arranged inside the crushing box, two groups of first crushing tools are arranged in the crushing chamber, two groups of crushing motors are arranged relatively at the two ends inside the base, each group of crushing motors is connected to a group of first crushing tools through a transmission belt and a reducer, and the two groups of first crushing tools are driven to rotate in the crushing chamber by the two groups of crushing motors. Compared with the current crushing equipment, the present invention is provided with a pretreatment mechanism, the pretreatment mechanism is arranged inside the feed box, and the outside of the feed box is provided with a liquid inlet pipe and a liquid outlet pipe, The liquid inlet pipe and the liquid outlet pipe are relatively arranged at the two ends of the pretreatment mechanism, the liquid inlet pipe is connected to the external water supply system, and the liquid outlet pipe is connected to the external electrolyte recovery system. When the present invention is working, the new energy battery to be crushed will first fall into the pretreatment mechanism, and the feed amount of the new energy battery to be crushed will be monitored by the pretreatment mechanism, so that the crushing motor can adjust the rotation speed in time according to the change of the feed amount, thereby balancing the energy consumption and wear of the crushing equipment on the basis of ensuring the crushing efficiency. Finally, the pretreatment mechanism provided in the present invention can remove the electrolyte in the new energy battery to be crushed to reduce the probability of corrosion of parts in the crushing box. When the pretreatment of the new energy battery to be crushed is completed, the new energy battery to be crushed will fall into the crushing chamber, and the new energy battery will be completely crushed by two groups of first crushing tools for subsequent recycling.

[0006] Furthermore, a maintenance chamber, a groove and a discharge channel are further provided inside the crushing box, and two groups of maintenance chambers are provided. The two groups of maintenance chambers are relatively arranged on both sides of the crushing chamber, and the groove is arranged below the crushing chamber. The groove is communicated with the two groups of maintenance chambers, and the discharge channel is arranged below the groove. A screening mechanism is provided inside the groove, and a first linear motor is provided on the inner wall of the groove. The working end of the first linear motor is connected to the screening mechanism. When the waste new energy batteries are crushed in the crushing chamber, the qualified battery fragments will pass through the screening mechanism and fall to the outside from the discharge channel, and the unqualified battery fragments will be intercepted by the screening mechanism and continue to be crushed in the crushing chamber. After the work of the present invention is completed, the first linear motor can drive the screening mechanism to move to the bottom of the maintenance chamber, so that the staff can clean and repair the screening mechanism in time.

[0007] Furthermore, the screening mechanism includes a mounting frame, a mounting hole is provided on the mounting frame, a bracket, a screen and a first electromagnet are provided in the mounting hole, the bracket is movably installed in the mounting hole by a vibrating spring rod, the screen is arranged above the bracket, and two groups of first electromagnets are provided, and the two groups of first electromagnets are relatively arranged below the two ends of the bracket. When the waste new energy batteries are crushed in the crushing chamber, the staff can intermittently turn on the first electromagnet. When the first electromagnet is turned on, the first electromagnet will generate a group of magnetic fields that attract the bracket, so that the bracket and the screen move down. When the first electromagnet is closed, under the action of the vibrating spring rod, the bracket and the screen will automatically move up. Through the above technical solution, when the waste new energy batteries are crushed in the crushing chamber, the bracket and the screen can vibrate spontaneously, so as to increase the falling speed of the qualified battery fragments and reduce the probability of clogging of the screen.

During operation, if the staff suddenly detects that the size of battery fragments coming out of the discharge channel is unqualified, the first linear motor can be directly turned on to move the group of mounting holes below the maintenance cavity to directly above the discharge channel, and the group of mounting holes previously aligned with the discharge channel is moved to directly below the other group of maintenance cavities, and then the staff can remove the screen from the bracket to replace it with a new one. Compared with the screening components currently used in crushing equipment, the present invention can replace the screen at any time without affecting the normal crushing of materials, thereby ensuring the continuity of production.

[0009] Furthermore, the pretreatment mechanism is provided with two groups, and the two groups of pretreatment mechanisms are relatively arranged at the two ends of the interior of the feed box, and a dividing rack is arranged between the two groups of pretreatment mechanisms. The dividing rack is a V-shaped structure, and a group of telescopic plates are arranged at both ends of the interior of the dividing rack. Each group of telescopic plates is connected to the dividing rack through a group of second linear motors. The present invention can ensure that when one of the pretreatment mechanisms fails, the waste new energy batteries can continue to be crushed by setting two groups of pretreatment mechanisms, thereby ensuring the continuity of production. Finally, the present invention controls the extension length of the telescopic plate through the second linear motor, thereby ensuring that the waste new energy batteries can smoothly enter the pretreatment mechanism, and at the same time will not affect the discharge of the pretreated waste new energy batteries into the crushing chamber.

[0010] Furthermore, the pre-processing mechanism includes a first mounting seat, a second mounting seat and a support seat, the first mounting seat is arranged at the inner upper end of the feed box, the second mounting seat is arranged at the inner lower end of the feed box, the support seat is arranged below the second mounting seat, and an induction component is arranged at one end of the support seat close to the second mounting seat, a pre-crushing component and a first cylinder are arranged in the first mounting seat, the pre-crushing component is connected to the working end of the first cylinder, and a direction-changing motor is also arranged on the outer side of the feed box, and the direction-changing motor is connected to the support seat through a rotating shaft. When the waste new energy battery enters the second When the waste new energy batteries are in the second mounting seat, the feed amount of the waste new energy batteries is monitored by the sensing component, so that the crushing motor can adjust the rotation speed in time according to the change of the feed amount, and then the first cylinder controls the descent of the pre-crushing component, and the electrolyte in the waste new energy batteries flows out through the pre-crushing component, so as to ensure that when the subsequent waste new energy batteries are completely crushed in the crushing box, the parts in the crushing box will not be corroded. When the pretreatment of the waste new energy batteries is completed, the supporting seat and the second mounting seat are deflected toward the direction of the dividing rack through the changing motor, so as to discharge the pretreated waste new energy batteries into the crushing chamber.

[0011] Furthermore, a liquid guide groove is provided at the lower end of the interior of the second mounting seat, one end of the liquid guide groove is connected to the liquid inlet pipe, and the other end of the liquid guide groove is connected to the liquid outlet pipe. A fixing plate is provided above the liquid guide groove, and a sealing plate is provided on the side of the fixing plate close to the material distribution frame. The sealing plate is movably mounted on the side end of the material distribution frame through a second cylinder, and a through hole is provided on the fixing plate. An ultrasonic generator is provided inside the liquid guide groove. When the waste new energy battery enters the second mounting seat, the sealing plate is fitted with the second mounting seat, and when the pre-crushing component squeezes out the electrolyte in the waste new energy battery, the electrolyte is output through the external The water system continuously delivers clean water into the guide tank and submerges the waste new energy batteries in the second mounting seat. The aqueous solution absorbed with electrolyte is continuously pumped away through the external electrolyte recovery system. The cleaning of the waste new energy batteries is accelerated by the ultrasonic generator. When the waste new energy batteries no longer contain electrolyte, the external water delivery system is closed, and the clean water in the second mounting seat is completely pumped away through the external electrolyte recovery system. Then, the support seat and the second mounting seat are deflected toward the direction of the dividing rack through the changing motor. Finally, the sealing plate is driven away from the second mounting seat through the second cylinder. At this time, the pre-treated waste new energy batteries will be discharged into the crushing chamber.

When the waste new energy batteries just enter the second mounting seat, there is a gap between the support seat and the second mounting seat, and the induction spring will be compressed. The feed amount of the waste new energy batteries can be judged by detecting the size of the electrical signal generated by the piezoelectric sheet. When the feed amount of the waste new energy batteries is detected, the staff can turn on the third electromagnet to make the support seat and the second mounting seat tightly fixed together to ensure that when the subsequent pre-crushing component squeezes out the electrolyte in the waste new energy batteries, the second mounting seat shakes, thereby affecting the work of the pre-crushing component.

The two ends are connected, a second electromagnet is arranged between the two groups of liquid storage chambers, and a magnetic block is embedded in one end of each group of movable plates close to the second electromagnet. When the pre-crushing component in the present invention is working, the second electromagnet will intermittently change the magnetic field so that the two groups of movable plates can make reciprocating lifting movements in the two groups of liquid storage chambers. In the present invention, hydraulic oil is filled in the two groups of liquid storage chambers. When the two groups of movable plates make lifting movements, several groups of telescopic rods and pressing plates will make lifting movements synchronously, and the waste new energy batteries are crushed by several groups of second crushing tools arranged under the pressing plate so that the electrolyte in the waste new energy batteries can flow out.

When the pre-crushing assembly in the present invention is working, the first cylinder will first drive the lifting frame into the second mounting seat, at which time the second mounting seat will form a sealed space, and then the staff can extract the gas in the second mounting seat through the air pump, and then deliver the inert gas to the second mounting seat through the external inert gas delivery system, and finally intermittently change the magnetic field of the second electromagnet so that a plurality of groups of second crushing cutters hit the waste new energy batteries.

Compared with the current crushing equipment, the present invention is provided with a pretreatment mechanism, the pretreatment mechanism is arranged inside the feed box 4, and the outer side of the feed box 4 is provided with a liquid inlet pipe 41 and a liquid outlet pipe 4 3. The liquid inlet pipe 41 and the liquid outlet pipe 43 are relatively arranged at the two ends of the pretreatment mechanism, the liquid inlet pipe 41 is connected to the external water supply system, and the liquid outlet pipe 43 is connected to the external electrolyte recovery system. When the present invention is working, the new energy battery to be crushed will first fall into the pretreatment mechanism, and the feed amount of the new energy battery to be crushed will be monitored by the pretreatment mechanism, so that the crushing motor 3 can adjust the rotation speed in time according to the change of the feed amount, so as to balance the energy consumption and wear of the crushing equipment on the basis of ensuring the crushing efficiency. Finally, the pretreatment mechanism set in the present invention can remove the electrolyte in the new energy battery to be crushed to reduce the probability of corrosion of the parts in the crushing box 2. When the pretreatment of the new energy battery to be crushed is completed, the new energy battery to be crushed will fall into the crushing chamber 21, and the new energy battery will be completely crushed by two groups of first crushing tools 22 for subsequent recycling.

[0031] like Figure 4-Figure 6As shown, the interior of the crushing box 2 is also provided with a maintenance chamber 23, a groove 24 and a discharge channel 25. The maintenance chamber 23 is provided with two groups, and the two groups of maintenance chambers 23 are relatively arranged on both sides of the crushing chamber 21. The groove 24 is arranged below the crushing chamber 21, and the groove 24 is communicated with the two groups of maintenance chambers 23. The discharge channel 25 is arranged below the groove 24. A screening mechanism 26 is arranged inside the groove 24, and a first linear motor is arranged on the inner wall of the groove 24. The working end of the first linear motor is connected to the screening mechanism 26. When the waste new energy batteries are crushed in the crushing chamber 21, the qualified battery fragments will pass through the screening mechanism 26 and fall to the outside from the discharge channel 25, and the unqualified battery fragments will be intercepted by the screening mechanism 26 and continue to be crushed in the crushing chamber 21. After the work of the present invention is completed, the first linear motor can drive the screening mechanism 26 to move to the bottom of the maintenance chamber 23, so that the staff can clean and repair the screening mechanism 26 in time.

[0032] like Figure 4-Figure 6 As shown, the screening mechanism 26 includes a mounting frame 261, a mounting hole is provided on the mounting frame 261, a bracket 262, a screen 263 and a first electromagnet 264 are provided in the mounting hole, the bracket 262 is movably installed in the mounting hole through a vibrating spring rod, the screen 263 is arranged above the bracket 262, and the first electromagnet 264 is provided with two groups, and the two groups of first electromagnets 264 are relatively arranged below the two ends of the bracket 262. When the waste new energy battery is crushed in the crushing chamber 21, the staff can intermittently turn on the first electromagnet 264 When the first electromagnet 264 is turned on, the first electromagnet 264 will generate a set of magnetic fields that attract the bracket 262, so that the bracket 262 and the screen 263 move down. When the first electromagnet 264 is turned off, under the action of the vibrating spring rod, the bracket 262 and the screen 263 will automatically move up. Through the above technical solution, when the waste new energy batteries are crushed in the crushing chamber 21, the bracket 262 and the screen 263 can vibrate spontaneously, so as to increase the falling speed of the qualified battery fragments and reduce the probability of clogging of the screen 263.

[0033] like Figure 4-Figure 6 As shown, two groups of mounting holes are provided, each group of mounting holes is adapted to the discharge channel 25, and a bracket 262 and a screen 263 are provided in each group of mounting holes. The screen 263 is detachably mounted on the bracket 262 by countersunk screws, and a group of first electromagnets 264 are provided below both ends of each group of brackets 262. When the present invention crushes the new energy battery, one group of mounting holes is aligned with the discharge channel 25, and the other group of mounting holes is located below the maintenance cavity 23 (such as Figure 4As shown), during the working process, if the staff suddenly detects that the size of the battery fragments coming out of the discharge channel 25 is unqualified, the first linear motor can be directly turned on to move a group of mounting holes located below the maintenance chamber 23 to be directly above the discharge channel 25, and a group of mounting holes previously aligned with the discharge channel 25 are moved to be directly below another group of maintenance chambers 23. Then the staff can remove the screen 263 from the bracket 262 to replace it with a new screen 263. Compared with the screening components currently used in crushing equipment, the present invention can replace the screen 263 at any time without affecting the normal crushing of the material, thereby ensuring the continuity of production.

[0034] like Figure 3 , Figure 7 As shown, two groups of pretreatment mechanisms are provided, and the two groups of pretreatment mechanisms are relatively arranged at the two ends of the interior of the feed box 4, and a dividing rack 44 is provided between the two groups of pretreatment mechanisms. The dividing rack 44 is a V-shaped structure, and a group of telescopic plates 441 are provided at both ends of the interior of the dividing rack 44. Each group of telescopic plates 441 is connected to the dividing rack 44 through a group of second linear motors. By setting two groups of pretreatment mechanisms, the present invention can ensure that when one of the pretreatment mechanisms fails, the waste new energy batteries can still continue to be crushed, thereby ensuring the continuity of production. Finally, the present invention controls the extension length of the telescopic plate 441 through the second linear motor, thereby ensuring that the waste new energy batteries can smoothly enter the pretreatment mechanism, and at the same time will not affect the discharge of the pretreated waste new energy batteries into the crushing chamber 21.

[0035] like Figure 1-Figure 3 , Figure 8-Figure 10As shown, the pretreatment mechanism includes a first mounting seat 45, a second mounting seat 46 and a support seat 47. The first mounting seat 45 is arranged at the upper end of the interior of the feed box 4, the second mounting seat 46 is arranged at the lower end of the interior of the feed box 4, and the support seat 47 is arranged below the second mounting seat 46. An induction component is arranged at one end of the support seat 47 close to the second mounting seat 46. A pre-crushing component and a first cylinder 454 are arranged in the first mounting seat 45. The pre-crushing component is connected to the working end of the first cylinder 454. A direction-changing motor 42 is also arranged on the outside of the feed box 4. The direction-changing motor 42 is connected to the support seat 47 through a rotating shaft 471. When the waste new energy battery enters the first When the waste new energy batteries are in the second mounting seat 46, the feed amount of the waste new energy batteries is monitored by the sensing component, so that the crushing motor 3 can adjust the rotation speed in time according to the change of the feed amount, and then the first cylinder 454 is used to control the descent of the pre-crushing component, so that the electrolyte in the waste new energy batteries can flow out through the pre-crushing component, so as to ensure that when the subsequent waste new energy batteries are completely crushed in the crushing box 2, the parts in the crushing box 2 will not be corroded. When the pretreatment of the waste new energy batteries is completed, the support seat 47 and the second mounting seat 46 are deflected toward the direction of the distribution rack 44 through the reversing motor 42, so as to discharge the pretreated waste new energy batteries into the crushing chamber 21.

[0036] like Figure 1-Figure 3 , Figure 8-Figure 10 As shown, a liquid guide groove 462 is provided at the lower end of the interior of the second mounting seat 46, one end of the liquid guide groove 462 is connected to the liquid inlet pipe 41, and the other end of the liquid guide groove 462 is connected to the liquid outlet pipe 43. A fixing plate 461 is provided above the liquid guide groove 462, and a sealing plate 463 is provided on the side of the fixing plate 461 close to the material distribution rack 44. The sealing plate 463 is movably installed on the side end of the material distribution rack 44 through a second cylinder 464. A through hole is provided on the fixing plate 461. An ultrasonic generator is provided inside the liquid guide groove 462. When the waste new energy battery enters the second mounting seat 46, the sealing plate 463 fits with the second mounting seat 46. When the pre-crushing component squeezes out the electrolyte in the waste new energy battery, the liquid guide groove is connected through the external water supply system. Clean water is continuously delivered to 462 to submerge the waste new energy batteries in the second mounting seat 46, and the aqueous solution absorbed with electrolyte is continuously pumped out through the external electrolyte recovery system, and the cleaning of the waste new energy batteries is accelerated by the ultrasonic generator. When the waste new energy batteries no longer contain electrolyte, the external water delivery system is closed, and the clean water in the second mounting seat 46 is completely pumped out through the external electrolyte recovery system, and then the pre-crushing component is reset through the first cylinder 454, and the support seat 47 and the second mounting seat 46 are deflected toward the direction of the dividing rack 44 through the direction-changing motor 42, and finally the sealing plate 463 is driven away from the second mounting seat 46 by the second cylinder 464. At this time, the pre-treated waste new energy batteries will be discharged into the crushing chamber 21.

[0037] like Figure 8-Figure 9 As shown, the induction component includes an induction slot 472, a connecting frame 473 and a third electromagnet 474. The third electromagnet 474 is arranged at the middle position of the inner upper end of the support seat 47. There are two groups of induction slots 472. The two groups of induction slots 472 are relatively arranged on both sides of the inner upper end of the support seat 47. A group of connecting frames 473 are arranged in each group of induction slots 472. One end of the connecting frame 473 is connected to the second mounting seat 46, and the other end of the connecting frame 473 is connected to the induction slot 472 through an induction spring. A group of piezoelectric sheets are arranged below each group of connecting frames 473. When the energy battery just enters the second mounting seat 46, there is a gap between the support seat 47 and the second mounting seat 46, and the induction spring will be compressed. The feed amount of the used new energy battery can be judged by detecting the size of the electrical signal generated by the piezoelectric sheet. When the feed amount detection of the used new energy battery is completed, the staff can turn on the third electromagnet 474 to make the support seat 47 and the second mounting seat 46 tightly fixed together to ensure that the subsequent pre-crushing component will shake when squeezing out the electrolyte in the used new energy battery, thereby affecting the work of the pre-crushing component.

Two groups of liquid storage chambers 4533 are also arranged in the lifting frame 453, and a group of movable plates 4532 are arranged in each group of liquid storage chambers 4533. Each group of movable plates 4532 is movably installed in the liquid storage chamber 4533 through a compression spring rod, one group of liquid storage chambers 4533 is connected to the upper ends of the plurality of telescopic slots 4531, and the other group of liquid storage chambers 4533 is connected to the plurality of groups The lower ends of the telescopic grooves 4531 are connected, and a second electromagnet 4534 is arranged between the two groups of liquid storage chambers 4533. A magnetic block is inlaid on one end of each group of movable plates 4532 close to the second electromagnet 4534. When the pre-crushing assembly in the present invention is working, the second electromagnet 4534 will intermittently change the magnetic field so that the two groups of movable plates 4532 can perform reciprocating lifting motions in the two groups of liquid storage chambers 4533. In the present invention, hydraulic oil is filled in the two groups of liquid storage chambers 4533. When the two groups of movable plates 4532 perform lifting motions, several groups of telescopic rods 4537 and pressing plates 4535 will perform lifting motions synchronously, and the waste new energy batteries are crushed by several groups of second crushing cutters 45351 arranged below the pressing plates 4535 so that the electrolyte in the waste new energy batteries can flow out.

[0040] The working principle of the present invention is as follows: when working, the waste new energy batteries are first poured into the second mounting seat 46, and the sensing component monitors the feed amount of the waste new energy batteries so that the crushing motor 3 adjusts the rotation speed according to the change of the feed amount, and then the first cylinder 454 controls the descent of the pre-crushing component, and the electrolyte in the waste new energy batteries flows out through the pre-crushing component, and the external water supply system continuously delivers clean water to the guide liquid tank 462 to submerge the waste new energy batteries in the second mounting seat 46, and the aqueous solution absorbed with the electrolyte is continuously extracted through the external electrolyte recovery system, and the cleaning of the waste new energy batteries is accelerated through the ultrasonic generator. When the waste new energy batteries no longer contain electrolyte, the external water supply is closed. The water system is used, and the clean water in the second mounting seat 46 is completely pumped out through the external electrolyte recovery system, and then the pre-crushing assembly is reset through the first cylinder 454, and the support seat 47 and the second mounting seat 46 are deflected toward the direction of the dividing rack 44 through the reversing motor 42, and finally the sealing plate 463 is driven away from the second mounting seat 46 by the second cylinder 464. At this time, the pre-treated waste new energy batteries will be discharged into the crushing chamber 21, and the waste new energy batteries will be completely crushed by two groups of first crushing tools 22. Finally, the qualified battery fragments will pass through the screening mechanism 26 and fall to the outside from the discharge channel 25, and the unqualified battery fragments will be intercepted by the screening mechanism 26 and continue to be crushed in the crushing chamber 21.
