DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to specific embodiments. Figures 1 to 3 As shown:

[0020] Example 1: A magnetic separation device for recycling waste batteries includes a base plate 1, a conveyor belt 2 is provided on the base plate 1, a frame 3 is provided on the base plate 1 and is covered above the conveyor belt 2, a first sliding component is provided on the frame 3, and the first sliding component is slidably provided with two mounting plates 4, the mounting plates 4 slide horizontally and the sliding direction of the mounting plates 4 is perpendicular to the conveying direction of the conveyor belt 2.

[0021] A lifting mechanism is provided at the lower end of the mounting plate 4, and an electromagnet 7 is connected to the lower end of the lifting mechanism. The lifting mechanism controls the lifting and lowering of the electromagnet 7, thereby changing the distance between the electromagnet 7 and the conveyor belt 2. A second sliding assembly is provided on the frame 3 on both sides of the conveyor belt 2. The second sliding assembly moves in the horizontal direction, and the moving direction is parallel to the direction of the conveyor belt 2. The second sliding assembly includes a horizontal axis 11, and a material receiving hopper 13 with an upper end opening is rotatably provided on the horizontal axis 11. The rotation of the horizontal axis 11 controls the rotation of the material receiving hopper 13.

[0022] The first sliding assembly moves one of the electromagnets 7 to the top of the conveyor belt 2, uses the lifting mechanism to adjust the distance between the electromagnet 7 and the conveyor belt 2, and uses the magnetic force of the electromagnet 7 to adsorb the iron objects on the conveyor belt 2 onto the electromagnet 7. When more electromagnets 7 are adsorbed on the electromagnet 7, the first sliding assembly is controlled to move the electromagnet 7 that is full of iron objects to the side of the conveyor belt 2, and move the other electromagnet 7 to the top of the conveyor belt 2 to achieve seamless connection between the two electromagnets 7, thereby reducing the downtime when cleaning the electromagnet 7. The second sliding assembly controls the movement of the receiving hopper 13, so that the receiving hopper 13 is used to scrape the metal on the electromagnet 7.

[0023] Example 2: A magnetic separation device for recycling waste batteries, comprising a base plate 1, a conveyor belt 2 is provided on the base plate 1, a frame 3 is provided on the base plate 1 and is covered above the conveyor belt 2, a first sliding assembly is provided on the frame 3, the first sliding assembly is slidably provided with two mounting plates 4, the first sliding assembly includes a plurality of first guide shafts 5, the mounting plates 4 are all slidably connected to the first guide shafts 5, a first telescopic mechanism 6 parallel to the first guide shaft 5 is fixedly provided on the frame 3, the first telescopic mechanism 6 is fixedly connected to the mounting plate 4, the mounting plate 4 slides horizontally and the sliding direction of the mounting plate 4 is perpendicular to the conveying direction of the conveyor belt 2.

[0024] A lifting mechanism is provided at the lower end of the mounting plate 4, and an electromagnet 7 is connected to the lower end of the lifting mechanism. The lifting mechanism controls the lifting and lowering of the electromagnet 7, thereby changing the distance between the electromagnet 7 and the conveyor belt 2. The lifting mechanism includes a plurality of vertically extending second telescopic mechanisms 8, and the upper and lower ends of the second telescopic mechanisms 8 are rotatably connected to the mounting plate 4 and the electromagnet 7 respectively. The inclination of the electromagnet 7 is adjusted by controlling the length of the second telescopic mechanisms 8 connected to the two ends of the electromagnet 7, thereby changing the magnetic force of different areas of the electromagnet 7 on the iron objects on the conveyor belt 2, so that the thickness of the iron objects adsorbed on the electromagnet 7 is uniform.

[0025] A second sliding assembly is provided on the frame 3 on both sides of the conveyor belt 2. The second sliding assembly moves in the horizontal direction, and the moving direction is parallel to the direction of the conveyor belt 2. The second sliding assembly includes a transverse axis 11. The second sliding assembly includes a slider 10 and multiple second guide shafts 9. The slider 10 and the second guide shaft 9 are both slidingly connected. The transverse axis 11 is rotatably connected to the slider 10. A rotating motor 12 connected to the transverse axis 11 is provided on the slider 10. A material receiving hopper 13 with an upper end opening is rotatably provided on the transverse axis 11. The rotation of the transverse axis 11 controls the rotation of the material receiving hopper 13.

[0026] The receiving hopper 13 is in the shape of a step, and an inclined and extending scraper plate 14 is provided inside the receiving hopper 13 for rotation. An elastic member 15 connected to the scraper plate 14 is provided inside the receiving hopper 13. The elastic member 15 is a tension spring. Under the elastic force of the elastic member 15, the scraper plate 14 contacts the electromagnet 7, thereby scraping the metal on the electromagnet 7 and dropping it into the receiving hopper 13.

[0027] The specific working process is as follows: when performing magnetic separation, the first sliding component moves one of the electromagnets 7 to the top of the conveyor belt 2, and uses the lifting mechanism to adjust the distance between the electromagnet 7 and the conveyor belt 2. The magnetic force of the electromagnet 7 is used to adsorb the iron objects on the conveyor belt 2 onto the electromagnet 7. When more electromagnets 7 are adsorbed on the electromagnet 7, the first sliding component is controlled to move the electromagnet 7 that is full of iron objects to the side of the conveyor belt 2, and move the other electromagnet 7 to the top of the conveyor belt 2 to achieve seamless connection between the two electromagnets 7, thereby reducing the downtime of the conveyor belt 2 when cleaning the electromagnet 7. The second sliding component controls the movement of the receiving hopper 13, so that the scraper plate 14 contacts the electromagnet 7, and then reduces the power of the electromagnet 7. The receiving hopper 13 scrapes the metal on the electromagnet 7 and drops it onto the receiving hopper 13.
