[0022] The inner side of the hollow connecting shell 1 is hollow, and the inner side of the feed port 2 is connected to the inner side of the hollow connecting shell 1. The discharge collection box 12 is in the shape of a hollow rectangular body. The discharge collection box 12 is fixedly connected to one side of the lower end of the hollow connecting shell 1 through a fixed plate, so that the metal inside the feed port 2 can enter the discharge collection box 12 from the inside of the hollow connecting shell 1. The metal collection box 16 and the plastic collection box 17 slide on the inner side of the discharge collection box 12. Slide openings are provided on the inner sides of both ends of the discharge collection box 12. One end of the conveyor belt 13 is arranged on the upper middle part of the plastic collection box 17, and one end of the conveyor belt 13 is arranged on the upper middle part of the metal collection box 16. The lower end of the conveyor belt 13 is ten centimeters away from the upper ends of the metal collection box 16 and the plastic collection box 17, so as to facilitate the metal transportation on the outside of the conveyor belt 13. The sloped scraper 15 has the effect of scraping off the metal on the outside of the conveyor belt 13. The upper middle part of the conveyor belt 13 is arranged on the lower end of the triangular connecting block 18. One side of the sloped scraper 15 is connected to the conveyor belt 13. The belt 13 is fitted on one side, and the conveyor belt 13 rotates on the inner side of the upper end of the unloading concentration box 12 through the roller shaft. The triangular connecting block 18 is in the shape of a triangle, and the triangular connecting block 18 is fixedly connected to the inner side of the lower middle end of the hollow connecting shell 1, so as to guide the fallen metal. The fallen metal falls from one side of the triangular connecting block 18 to the upper end of the sloped scraper 15. The diameter of the first gear 4 is greater than the diameter of the second gear 7. The connecting cylindrical rod 8 is in the shape of a cylinder, and the connecting cylindrical rod 8 is fixedly connected to both sides of the cleaning drum 10. The outer side of the connecting cylindrical rod 8 is rotatably connected to the inner side of the hollow connecting shell 1. One side of the fixed support block 9 is fixedly connected to the lower end of the fixed upper scraper 19. One side of the fixed upper scraper 19 is fitted with the outer side of the electromagnet column 5, and the outer side of the cleaning drum 10 is fitted with the outer side of the electromagnet column 5, so that the connecting cylindrical rod 8 drives the cleaning drum 10 to rotate stably on the inner side of the hollow connecting shell 1, thereby cleaning the metal outside the electromagnet column 5 under the beating of the cleaning nylon strip 11.

[0023] Working process: When the device is in use, the external power supply is energized. When it is necessary to screen the metal and the plastic, the material is put in from the feed port 2 fixedly connected to the upper end of the hollow connecting shell 1. At this time, the plastic and metal fall to the upper end of the guide scraper 6 fixedly connected to the inner side of the hollow connecting shell 1 and the outer side of the electromagnet column 5. Under the adsorption of the electromagnet column 5, part of the metal is magnetically adsorbed on the outer side of the electromagnet column 5. At this time, the plastic and metal will be blocked on the inner side of the upper end of the hollow connecting shell 1 and the upper end of the guide scraper 6. The upper end of the guide scraper 6 has a certain slope to facilitate the flow of materials. The motor 3 fixedly connected to one side of the hollow connecting shell 1 is started. The rotation of the main shaft of the motor 3 drives the electromagnet column 5 fixedly connected to the end of the main shaft to rotate. The rotation of the electromagnet column 5 drives the adsorbed metal to rotate. At the same time, the electromagnetic The plastic on the outside of the iron column 5 falls evenly inside the hollow connecting shell 1. When the electromagnet column 5 rotates, it has the effect of evenly contacting the material on the outside of the electromagnet column 5. At the same time, when the electromagnet column 5 rotates, the fixed upper scraper 19 fixedly connected to the inner side of the hollow connecting shell 1 scrapes the outer side of the electromagnet column 5. At the same time, during the rotation of the main shaft of the motor 3, the first gear 4 fixedly connected to the outer side of the main shaft of the motor 3 rotates. The rotation of the first gear 4 drives the second gear 7 meshing on the outer side to rotate. Since the diameter of the first gear 4 is greater than the diameter of the second gear 7, the rotation speed of the second gear 7 is greater than the rotation speed of the first gear 4. At the same time, the direction of the first gear 4 is opposite to that of the second gear 7. The rotation of the second gear 7 drives the connecting cylindrical rod 8 fixedly connected on the inner side to rotate, and the outer side of the connecting cylindrical rod 8 The side rotation connection is connected to the inner side of the hollow connecting shell 1, which plays the effect of driving the connecting cylindrical rod 8 to drive the cleaning drum 10 to rotate stably. The rotation of the connecting cylindrical rod 8 drives the cleaning drum 10 fixedly connected on one side to rotate. The rotation of the cleaning drum 10 drives the cleaning nylon strip 11 fixedly connected on the outside to rotate. The cleaning nylon strip 11 plays the effect of cleaning the metal on the surface of the electromagnet column 5. At the same time, the lower end of the material guide scraper 6 plays the effect of scraping the metal on the surface of the electromagnet column 5. One side of the lower end of the material guide scraper 6 is in contact with the outer side of the electromagnet column 5, so that the metal falls on the side of the triangular connecting block 18 fixedly connected to the inner side of the lower end of the hollow connecting shell 1. According to the shape of the triangular connecting block 18, the triangular connecting block 18 plays the effect of guiding the fallen metal, and the fallen metal falls from one side of the triangular connecting block 18. At the upper end of the sloped scraper 15, plastic and a small amount of metal fall from the upper end of the sloped scraper 15 into the metal aggregate box 16. At the same time, plastic and a small amount of metal fall from the rear end side of the triangular connecting block 18 to the upper end of the conveyor belt 13. The electromagnetic strip 14 fixedly connected to the inner side of the conveyor belt 13 has the effect of adsorbing the metal. The conveyor belt 13 has the effect of transporting the fallen plastic to the inside of the plastic aggregate box 17. There is a distance of ten centimeters between the conveyor belt 13 and the plastic aggregate box 17 and the metal aggregate box 16, which is convenient for transporting the metal outside the conveyor belt 13. The sloped scraper 15 has the effect of scraping off the metal outside the conveyor belt 13. The metal scraped off by the sloped scraper 15 falls into the metal aggregate box 16 again, thereby facilitating the collection of the metal aggregate box 16 and the plastic aggregate box 17.
