[0053] The operation process is as follows: first, the main gear 202b is driven to rotate through the corresponding controller, when the main gear 202b rotates, the three secondary gears 202c around the main gear 202b are driven to rotate, and the rotation directions of the main gear 202b and the secondary gear 202c are opposite, and one side of the main crushing shaft 202a and the secondary crushing shaft 202d penetrates the crushing box 201a and is fixed in the main gear 202b and the secondary gear 202c respectively, so that the main crushing shaft 202a and the secondary crushing shaft 202d can rotate and the rotation directions are opposite, so that the crushing blades 202e arranged on the surfaces of the two can crush the lithium iron phosphate battery, in addition, a gear ring 202f is arranged on the outside of the secondary gear 202c and the two are meshed and connected, so that when the secondary gear 202c is driven by the main gear 202b, the gear ring 202f also rotates, one end of the primary crushing assembly 202 is fixedly connected to one side of the crushing box 201a, that is, the gear ring 202f can drive the crushing box 201a to rotate, and the crushing box 201a is provided with a sieve plate 201c and a baffle plate 201d inside, through the cooperation of the crushing box 201a and the sieve plate 201c, the larger particles of the lithium iron phosphate battery pieces are left in the crushing box 201a, then the baffle plate 201d is used to carry the pieces left in the crushing box 201a, and with the rotation of the crushing box 201a, the pieces fall on the main crushing shaft 202a and the main crushing shaft 202a again, and are crushed for one or more times.

[0054] In the third embodiment, the difference from the previous embodiment is that the waste lithium iron phosphate battery recycling crushing device comprises a secondary crushing assembly 203, which comprises a first crushing roller 203c arranged at the bottom of the shell 102, a driving gear 203a arranged on one side of the first crushing roller 203c, a driven gear 203b arranged on one side of the driving gear 203a, and a driving gear 203a arranged on one side of the driven gear 203b; wherein the driving gear 203a and the driven gear 203b are meshed and connected. Figures 3-7 Specifically, the driving assembly 204 comprises a driving motor 204a arranged at the top of the shell 102, a first pulley 204b arranged at the driving end of the driving motor 204a, a first connecting belt 204c sleeved outside the first pulley 204b, a second pulley 204d arranged inside the first connecting belt 204c, a second connecting belt 204e sleeved outside the second pulley 204d, and a third pulley 204f arranged inside the second connecting belt 204e; wherein the first pulley 204b is fixed at the driving end of the driving assembly 204, the second pulley 204d is fixed on one side of the main gear 202b, and the third pulley 204f is fixed on one side of the driving gear 203a.

[0055]

[0056] ​The operation process is as follows: first, the driving motor 204a is started to rotate the first pulley 204b fixed at the driving end of the driving motor 204a, then the second pulley 204d is rotated through the action of the first connecting belt 204c, and the second pulley 204d is fixedly connected with the main gear 202b, and the second pulley 204d rotates to drive the main gear 202b to rotate, in addition, the second connecting belt 204e is arranged on the outer wall of the second pulley 204d, and the other end of the second connecting belt 204e is connected with the third pulley 204f, that is, the third pulley 204f is rotated through the rotation of the second pulley 204d and the second connecting belt 204e, and the third pulley 204f is fixedly connected with the driving gear 203a, that is, the driving gear 203a can rotate synchronously with the third pulley 204f, in addition, the driven gear 203b is meshingly connected on one side of the driving gear 203a, therefore, the driving gear 203a and the driven gear 203b can rotate, and the rotating directions are opposite, and the first crushing roller 203c and the second crushing roller 203d are fixedly connected with the driving gear 203a and the driven gear 203b respectively, so that the first crushing roller 203c and the second crushing roller 203d also rotate, when the semi-finished product crushed material passes through, the semi-finished product crushed material is further crushed.

[0057] In the fourth embodiment, referring to Figure 1 and 8 , the third embodiment of the present application is different from the previous embodiment, which provides a waste lithium iron phosphate battery recycling and crushing device, further comprising a separation component 300, including a metal separation assembly 301 arranged in the inside of the base 101, and a non-metal separation assembly 302 arranged on one side of the base 101, the metal separation assembly 301 includes a discharging port 301a penetrating through the top of the base 101, a temporary storage chamber 301b opened in the inside of the base 101, a guide plate 301c arranged in the inside of the temporary storage chamber 301b, and an electromagnet 301d arranged in the inside of the guide plate 301c.

[0058] Specifically, the non-metal separation assembly 302 includes a separation tower 302a arranged on one side of the base 101, a conical hopper 302b arranged in the inside of the separation tower 302a, a spiral groove 302c arranged in the inside of the separation tower 302a corresponding to the upper side of the conical hopper 302b, an air outlet 302d penetrating through the top of the separation tower 302a, an air inlet 302e penetrating through one side of the separation tower 302a, a vacuum pump 302f arranged on one side of the air inlet 302e, and a communication pipeline 302g arranged at one end of the vacuum pump 302f.

[0059] The electromagnet 301d is fixed at the bottom of the guide plate 301c, and the guide plate 301c is made of non-metal material to avoid affecting the performance of the electromagnet 301d. One end of the communication pipeline 302g penetrates the base 101 and is connected with the temporary storage chamber 301b, and the other end is connected with the vacuum pump 302f to extract the semi-finished product into the separation tower 302a.

[0060] The operation process is as follows: first, the electromagnet 301d separates the metal substances in the semi-finished product. Under the action of the guide plate 301c, the gravity of the semi-finished product itself will make it slowly descend, and then the semi-finished product is extracted by the vacuum pump 302f. The semi-finished product is high-speed taken into the inside of the separation tower 302a along the tangential direction of the separation tower 302a, that is, the inlet 302e, and the semi-finished product enters the inside of the separation tower 302a and moves along the spiral groove 302c, that is, the linear motion becomes the circular motion. The semi-finished product rotating downward will enter the conical hopper 302b. Because the conical hopper 302b shrinks to the center of the separation tower 302a, its tangential speed is constantly increasing. When it reaches a certain position of the conical hopper 302b, it reverses upward in the same direction of rotation, forming an internal rotating airflow. Because the density of the metal substances and the non-metal substances in the semi-finished product is different, the centrifugal force generated by them is also different. The metal substances with larger density are thrown to the outer circle and contact the tower wall of the separation tower 302a, so they lose the inertial force, and fall along the tower wall of the separation tower 302a by the momentum of the speed of entering the separation tower 302a and the downward gravity. The non-metal substances with smaller density will be discharged from the exhaust port 302d along with the internal rotating airflow.
