A concave protective shell 1021 is fixed on the frame plate 201 on one side of the two conveyor belts 2 close to the inner wall of the box body 1. The bottom ends of the two protective shells 1021 are in contact with the top walls on both sides of the magnetic material collection box 102. The two protective shells 1021 are both at two sets of electromagnets 504. One end of the magnetic material collection box 102 passes through the outer wall of the box body 1 and is fixedly connected to a pull plate 1022. The side of the box body 1 away from the discharge pipe 101 is A non-magnetic material conduit 103 is fixed, and the length of the non-magnetic material conduit 103 is greater than the width of two conveyor belts 2.

[0023] When processing waste batteries, firstly, discharge the waste batteries to ensure the safety of subsequent crushing, use a crusher to screen and crush the waste batteries to break them into smaller particles, use screening equipment to classify the crushed waste particles to ensure the consistency of crushing size, and then place two recycling boxes at the discharge port 105, and set a baffle in the middle to collect other subsequent waste materials and non-magnetic metal waste.

[0025] When the dual-axis motor 203 controls the conveyor belt 206 to move, the large sprocket 406 installed is driven to rotate through the conveying end, and the large sprocket 406 drives the small sprocket 407 to rotate through the second transmission chain 408. The small sprocket 407 drives the inserted shaft 403 to rotate, and the shaft 403 drives the installed transmission sprocket 404 to rotate. At this time, the transmission sprocket 404 drives the remaining transmission sprockets 404 through the first transmission chain 405, so that all the shafts 403 rotate synchronously and in the same direction. The rotating multiple shafts 403 will drive the The convex push block 4031 below the mounting plate 401 rotates.

The top blocks 402 at different angles will make the time for the conveyor belt 206 to be lifted up different times, so as to ensure the vibration effect on the granular waste.

[0026] See also Figure 2-5As shown, the magnetic assembly 5 includes a fixed block 501 and two groups of electromagnets 504. The fixed block 501 is located between the two conveyor belts 2 and the top end is fixedly connected to the top wall of the box body 1. The two groups of electromagnets 504 are respectively located above the conveyor belts 206. A moving block 506 is provided below the fixed block 501. Both sides of the moving block 506 are located above the two conveyor belts 206 and are provided with guide plates 505. The two guide plates 505 cooperate with each group of electromagnets 504. The two rotating magnets 7 are both penetrated in the conveying roller 202 away from the feeding tube 101. Two electric telescopic cylinders 502 are installed on the top of the box body 1 by bolts, and the telescopic ends of the two electric telescopic cylinders 502 are successively penetrated through the top wall of the box body 1 and the fixed block 501 and connected with the connecting plate 503, and each group of electromagnets 504 are fixed at both ends of the connecting plate 503, and a horizontal plate 6 is provided below the moving block 506, and the horizontal plate 6 is located above the transmission system. Both sides of the horizontal plate 6 are fixedly connected to the outer wall of the frame plate 201, and a plurality of ball bearings 5061 are embedded in the bottom end of the moving block 506, and the plurality of ball bearings 5061 are rollingly connected to the upper surface of the horizontal plate 6, and sliders 507 are welded to the bottom of the two side walls of the moving block 506, and the cross-sections of the two sliders 507 are concave, and the two sliders 507 are slidably installed on the electric slide rail 2011, and the two electric slide rails 2011 are fixedly connected to the outer wall of the frame plate 201 by screws, and the two guide plates 505 are inclined, and the width of the two guide plates 505 is greater than the width of the electromagnet 504.

[0027] When the magnetic assembly 5 is working, the telescopic ends of the two electric telescopic cylinders 502 will push the connecting plate 503 downward, and the downward moving connecting plate 503 drives the electromagnet 504 to move, so that the electromagnet 504 approaches the conveyor belt 206 and is energized to generate magnetism, so as to magnetically adsorb the vibrated particle waste passing below, and the magnetic metal waste in the particle waste will be separated; When it is necessary to collect magnetic waste again, the controller will control the electric telescopic cylinder 502 and the corresponding electromagnet 504 in turn to move up and cut off the power. At this time, starting the electric slide rail 2011 will control the movement of the slider 507, and the two sliders 507 will drive the moving block 506 to move, so that the moving block 506 moves along the horizontal plate 6 through the ball 5061, and drives the guide plates 505 on both sides to move until the guide plates 505 are located below the electromagnet 504 that needs to be powered off. At this time, the electromagnet 504 is turned off and the electromagnetic properties disappear, and the adsorbed magnetic metal waste will fall and fall into the magnetic material collection box 102 through the protective shell 1021 along the inclination angle of the guide plate 505, wherein the staggered recovery of the two groups of electromagnets 504 can ensure non-stop operation. Finally, the staff can pull the magnetic material collection box 102 out of the box body 1 through the pull plate 1022 to centrally process the collected magnetic metal waste.

[0028] The working principle of the present invention is: When processing the waste batteries, the waste batteries are first discharged to ensure the safety of subsequent crushing. The waste batteries are crushed by a crusher to break them into smaller particles. The crushed waste is classified by screening equipment to ensure the consistency of the crushed size. Then two recycling boxes are placed at the discharge port 105, and a baffle is set in the middle to collect other subsequent waste and non-magnetic metal waste. At this time, the staff pours the granular waste into the box body 1 through the discharge pipe 101, and the waste is diverted when passing through the diverter plate 1011 and sent to the two conveyor belts 206 by two guide pipes 1012; At this time, the staff starts the dual-axis motor 203 and supplies power to the magnetic component 5 through the controller. The two output ends of the dual-axis motor 203 respectively drive the connected conveying rollers 202 to rotate, and the conveyor belt 206 is controlled to move by the rotating conveying rollers 202. The moving conveyor belt 206 moves with the fallen particle waste. When the dual-axis motor 203 controls the movement of the conveyor belt 206, the large sprocket 406 installed is driven to rotate through the conveying end. The large sprocket 406 drives the small sprocket 407 to rotate through the second transmission chain 408. The small sprocket 407 drives the inserted shaft 403 to rotate, and the shaft 403 drives the installed transmission sprocket 404 to rotate. At this time, the transmission sprocket 404 drives the remaining transmission sprockets 404 through the first transmission chain 405, so that all the shafts 403 rotate synchronously and in the same direction. The rotating multiple shafts 403 drive the convex push block 4031 located below the mounting plate 401 to rotate. When the convex end of the convex push block 4031 rotates to the upper side, it pushes the bottom end of the top block 402 to move upward. The top block 402 moves along the square through hole 4011, and the limiting plate 4021 also moves along the limiting groove 4012 to prevent the top block 402 from separating from the mounting plate 401. The top end of the moving top block 402 will lift up the conveyor belt 206. The top blocks 402 at different angles will cause the conveyor belt 206 to be lifted up at different times. The telescopic ends of the two electric telescopic cylinders 502 will push the connecting plate 503 downward, and the downward moving connecting plate 503 will drive the electromagnet 504 to move, so that the electromagnet 504 will approach the conveyor belt 206, and will be energized to generate magnetism, and the granular waste passing below and being vibrated will be magnetically adsorbed, and the magnetic metal waste in the granular waste will be separated. When the magnetic waste needs to be collected, the controller will control the electric telescopic cylinder 502 and the corresponding electromagnet 504 in turn to move up and cut off the power. At this time, starting the electric slide rail 2011 will control the slider 507 to move, and the two sliders 507 will drive the moving block 506 to move , so that the moving block 506 moves along the horizontal plate 6 through the ball bearing 5061, and drives the guide plates 505 on both sides to move, until the guide plates 505 are located below the electromagnet 504 that needs to be powered off, at which time the electromagnet 504 is powered off and the magnetic properties disappear, and the adsorbed magnetic metal waste will fall down and fall into the magnetic material collection box 102 through the protective shell 1021 along the inclination angle of the guide plate 505, wherein the staggered recovery of the two groups of electromagnets 504 can ensure non-stop operation, and finally the staff can pull the magnetic material collection box 102 out of the box body 1 through the pull plate 1022, and the collected magnetic metal waste is centrally processed; As for the remaining waste at the other end of the moving conveyor belt 2, the rotating magnet 7 rotates along with the conveyor roller 202, which will generate an alternating magnetic field. When the non-magnetic metal waste with conductive properties in the waste passes through this alternating magnetic field, eddy current will be generated and the conductive metal and the remaining waste will be separated by repulsive force from the magnetic field. The conductive metal and the remaining waste will be discharged along the non-magnetic material conduit 103, and the conductive metal will attract repulsive force and fall to the other side of the partition 1031 to achieve screening.
