Description

Technical Field

[0001] The present 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 produced and used in large quantities. 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 sharply, 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 batteries 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 two "waste battery crushing devices" each disclose a method for crushing waste batteries, but this crushing method can easily cause damage to internal components 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 components such as screens, but the screens 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, they usually have to stop the equipment before replacing the screen. This operation method is not only not conducive to production continuity, 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 equipment for recycling waste new energy batteries, the crushing equipment comprising a base, a crushing box, a crushing motor and a feed box, the crushing box being arranged above the base, the feed box being arranged above the crushing box, a crushing chamber being arranged inside the crushing box, two groups of first crushing tools being arranged inside the crushing chamber, two groups of crushing motors being arranged relatively at the two ends of the interior of the base, each group of crushing motors being 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 pre-treatment mechanism, the pre-treatment mechanism being arranged inside the feed box, and a liquid inlet pipe and a liquid outlet pipe being arranged on the outside of the feed box, 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 pretreatment mechanism monitors the feed amount of the new energy battery to be crushed 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 cutters for subsequent recycling.

[0006] Furthermore, the interior of the crushing box is also provided with a maintenance chamber, a groove and a discharge channel. The maintenance chamber is provided with two groups, and the two groups of maintenance chambers are relatively arranged on both sides of the crushing chamber. The groove is arranged below the crushing chamber, and the groove is communicated with the two groups of maintenance chambers. 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 into the discharge channel to the outside world, and the unqualified battery fragments will be intercepted by the screening mechanism and continue to be crushed in the crushing chamber. After the work is completed, the present invention can drive the screening mechanism to move to the bottom of the maintenance chamber through the first linear motor, so that the staff can clean and repair the screening mechanism in time.

[0007] Further, the screening mechanism comprises a mounting frame, the mounting frame is provided with a mounting hole, a support, a screen and a first electromagnet are arranged in the mounting hole, the support is movably mounted in the mounting hole through a vibrating spring rod, the screen is arranged above the support, and the first electromagnet is provided with two groups, the two groups of first electromagnets are oppositely arranged below the two ends of the support. When the waste new energy battery is crushed in the crushing cavity, the staff can intermittently turn on the first electromagnet. When the first electromagnet is turned on, the first electromagnet generates a group of magnetic fields that attract the support, so that the support and the screen move downward. When the first electromagnet is turned off, the support and the screen will automatically move upward under the action of the vibrating spring rod. Through the above technical scheme, when the waste new energy battery is crushed in the crushing cavity, the support and the screen can spontaneously vibrate, so as to improve the falling speed of the crushed qualified battery pieces and reduce the probability of screen blockage.

[0008] Further, the mounting hole is provided with two groups, each group of mounting holes is matched with the discharge channel, and a support and a screen are arranged in each group of mounting holes. The screen is detachably mounted on the support through a countersunk screw. One group of first electromagnets is arranged below the two ends of each group of supports. When the new energy battery is crushed, one group of mounting holes is aligned with the discharge channel, and the other group of mounting holes is located below the maintenance cavity. During the working process, if the staff suddenly detects that the size of the battery pieces 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 the directly above the discharge channel, and the group of mounting holes previously aligned with the discharge channel is moved to the directly below the other group of maintenance cavities. Then the staff can detach the screen from the support to replace a new screen. Compared with the screening components used in the current crushing equipment, the present application can replace the screen at any time without affecting the normal crushing of the material, thereby ensuring the continuity of production.

[0009] Further, the pretreatment mechanism is provided with two groups, and the two groups of pretreatment mechanisms are oppositely arranged at the two ends inside the feeding box. A material distribution frame is arranged between the two groups of pretreatment mechanisms. The material distribution frame has a V-shaped structure, and a set of telescopic plates is arranged at the two ends inside the material distribution frame. Each group of telescopic plates is connected with the material distribution frame through a group of second linear motors. By arranging two groups of pretreatment mechanisms, the present application can ensure that the waste new energy battery can continue to be crushed when one group of pretreatment mechanisms fails, thereby ensuring the continuity of production. Finally, the present application controls the extension length of the telescopic plates through the second linear motor, so as to ensure that the waste new energy battery can smoothly enter the pretreatment mechanism, and the pretreated waste new energy battery can be discharged into the crushing cavity without affecting the discharge.

[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 upper end of the interior of the feed box, the second mounting seat is arranged at the lower end of the interior 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 outside 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 first 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. 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 waste new energy batteries are completely crushed in the crushing box later, the parts in the crushing box will not be corroded. When the pretreatment of the waste new energy batteries is completed, the support seat and the second mounting seat are deflected toward the direction of the distribution 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 fits 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 liquid tank and submerges the waste new energy batteries in the second mounting seat. The aqueous solution that absorbs the electrolyte is continuously extracted through the external electrolyte recovery system. The ultrasonic generator is used to accelerate the cleaning of the waste new energy batteries. When the waste new energy batteries no longer contain electrolyte, the external water supply system is closed, and the clean water in the second mounting seat is completely extracted through the external electrolyte recovery system. Then, the support seat and the second mounting seat are deflected toward the direction of the material distribution rack through the changing motor. Finally, the sealing plate is driven away from the second mounting seat by 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 battery just enters the second mounting seat, the support base and the second mounting seat have a gap, and the induction spring is compressed at the same time. The amount of waste new energy battery can be judged by detecting the size of the electric signal generated by the piezoelectric sheet. When the amount of waste new energy battery is detected, the staff can start the third electromagnet to tightly fix the support base and the second mounting seat together, so as to ensure that the second mounting seat shakes when the electrolyte in the waste new energy battery is squeezed out by the pre-crushing assembly, and then affects the work of the pre-crushing assembly.

When the pre-crushing assembly in the application works, the second electromagnet will change the magnetic field intermittently, so that the two groups of movable plates do reciprocating lifting motion in the two groups of liquid storage chambers. The two groups of movable plates do reciprocating lifting motion in the two groups of liquid storage chambers. When the two groups of movable plates do reciprocating lifting motion, a plurality of groups of telescopic rods and the pressing plate do synchronous lifting motion, and a plurality of groups of second crushing cutters arranged below the pressing plate make the waste new energy battery be crushed, so that the electrolyte in the waste new energy battery flows out.

The last end of the three-way pipe is connected to the air pump. When the pre-crushing assembly of the present invention is working, the first cylinder will first drive the lifting frame into the second mounting seat. At this time, the second mounting seat will form a sealed space. Then the staff can use the air pump to extract the gas in the second mounting seat, and then deliver the inert gas to the second mounting seat through the external inert gas delivery system. Finally, the magnetic field of the second electromagnet is intermittently changed to make several groups of second crushing cutters hit the waste new energy batteries.

The amount of waste new energy battery feed can be judged by detecting the size of the electric signal generated by the piezoelectric sheet. After the amount of waste new energy battery feed is detected, the third electromagnet 474 can be turned on to tightly fix the support seat 47 and the second mounting seat 46 together, so as to ensure that the second mounting seat 46 shakes when the electrolyte in the waste new energy battery is squeezed out by the subsequent pre-crushing assembly, and then affects the work of the pre-crushing assembly.

[0038] As shown in FIG. 3, Figure 11-12 , the pre-crushing assembly comprises a lifting frame 453, a pressing plate 4535 is arranged below the lifting frame 453, a plurality of groups of second crushing cutters 45351 are arranged below the pressing plate 4535, a plurality of groups of telescopic grooves 4531 are arranged in the lifting frame 453, a group of telescopic rods 4537 is arranged in each group of telescopic grooves 4531, the working end of each group of telescopic rods 4537 is connected with the pressing plate 4535, two groups of liquid storage chambers 4533 are further arranged in the lifting frame 453, a group of movable plates 4532 is 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 the compression spring rod, one group of liquid storage chambers 4533 is communicated with the upper ends of the plurality of groups of telescopic grooves 4531, the other group of liquid storage chambers 4533 is communicated with the lower ends of the plurality of groups of telescopic grooves 4531, a second electromagnet 4534 is arranged between the two groups of liquid storage chambers 4533, and a magnetic block is embedded on one end of each group of movable plates 4532 close to the second electromagnet 4534. In the pre-crushing assembly in the application, the magnetic field of the second electromagnet 4534 changes intermittently, so that the two groups of movable plates 4532 make reciprocating lifting motion in the two groups of liquid storage chambers 4533. The application fills hydraulic oil in the two groups of liquid storage chambers 4533. When the two groups of movable plates 4532 make lifting motion, the plurality of groups of telescopic rods 4537 and the pressing plate 4535 make synchronous lifting motion. The second crushing cutters 45351 arranged below the pressing plate 4535 crush the waste new energy battery, so that the electrolyte in the waste new energy battery flows out.

[0039] As Figure 3 , Figure 11-12 As shown, the pre-crushing assembly also includes a first connecting pipe 451 and a second connecting pipe 452. The first connecting pipe 451 is connected to the external inert gas delivery system, and the second connecting pipe 452 is connected to the external environment. The lower end of the lifting frame 453 is provided with an exhaust groove 4536, and the pressure plate 4535 is provided with a plurality of exhaust holes. The interior of the lifting frame 453 is also provided with an air pump 4538 and a three-way pipe 45381. The air pump 4538 is connected to the exhaust groove 4536. One end of the three-way pipe 45381 is connected to the first connecting pipe 451 through a first valve and a first bellows, and the other end of the three-way pipe 45381 is connected to the second connecting pipe 452 through a second valve and a second bellows. The last end of the tube 45381 is connected to the air pump 4538. When the pre-crushing assembly of the present invention is working, the first cylinder 454 will first drive the lifting frame 453 into the second mounting seat 46. At this time, the second mounting seat 46 will form a sealed space. Then the staff can use the air pump 4538 to extract the gas in the second mounting seat 46, and then use the external inert gas delivery system to deliver inert gas to the second mounting seat 46. Finally, the magnetic field of the second electromagnet 4534 is intermittently changed to make several groups of second crushing tools 45351 collide with the used new energy batteries. Through the above technical solution, the risk of explosion of used new energy batteries during the crushing process can be effectively avoided.

[0040] The working principle of the present invention is as follows: when working, first pour the waste new energy batteries 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 controls the descent of the pre-crushing component through the first cylinder 454, so that the electrolyte in the waste new energy batteries flows out through the pre-crushing component, and continuously delivers clean water to the guide liquid tank 462 through the external water supply system to submerge the waste new energy batteries in the second mounting seat 46, and continuously extracts the aqueous solution that absorbs the electrolyte through the external electrolyte recovery system, and accelerates the cleaning of the waste new energy batteries through the ultrasonic generator. When the waste new energy batteries no longer contain electrolyte, the external 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 distribution 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.

[0041] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the application.
