Description

Technical Field

[0001] This utility model belongs to the technical field of material sorting, specifically, it relates to a sorting device for metals and non-metals. Background Technology

[0002] After recycling waste electrical appliances, important components such as motors and transmissions are removed, and the remaining parts and casings are usually crushed. After crushing, the materials need to be sorted according to different materials for further recycling. During sorting, metals and non-metals need to be separated. Currently, eddy current separators are commonly used for metal-non-metal separation. Eddy current separators are based on the principles of electromagnetic induction and Lorentz force. They separate non-ferrous metals from non-metals by generating eddy currents in a conductor within a high-frequency alternating magnetic field, creating a repulsive force. When materials containing conductive metals (such as copper and aluminum) pass through the high-frequency alternating magnetic field generated by a high-speed rotating magnetic drum, eddy currents are generated inside the metal due to electromagnetic induction. The magnetic field generated by the eddy currents is opposite to the original magnetic field. According to Lenz's law, the metal particles are repelled by the Lorentz force and ejected from the material flow. However, when the sorted material contains ferrous metals, the ferrous metals can cause the equipment to overheat, damaging the conveyor belt and sorting equipment, posing a significant safety hazard.

[0003] In view of this, this utility model is proposed. Utility Model Content

The intermediate removal support 5 has a portal frame structure, and lifting and lowering mechanisms are provided on both sides of the intermediate removal support 5. The chute 6 has an electric telescopic rod 8 installed on the top of the intermediate removal bracket 5. The lower end of the electric telescopic rod 8 is connected to a lower baffle 7. Lifting guide rods 29 are fixed at both ends of the lower baffle 7. The lifting guide rods 29 are fitted into the lifting and matching chute 6. A side bracket 10 is fixedly installed on the side of the intermediate removal bracket 5. A pushing power box 11 is fixedly installed on the side bracket 10. A horizontally movable pushing connecting plate 18 is installed below the pushing power box 11. A pushing plate 9 is installed below the pushing connecting plate 18 for pushing and collecting ferrous metal on the intermediate sorting plate 20.

[0020] The side of the lower baffle 7 abuts against the lower end of the middle sorting plate 20. The contact surface between the pusher plate 9 and the middle sorting plate 20 is a sawtooth structure. The contact position, shape, and specifications of the pusher plate 9, the middle sorting plate 20, and the lower baffle 7 are matched to ensure a good pushing and collecting effect.

[0021] A pusher motor 17 is installed at one end of the pusher power box 11. A transmission screw 23 is installed inside the pusher power box 11. A movable nut seat 22 is installed on the transmission screw 23. The movable nut seat 22 is fixedly connected to the pusher connecting plate 18. A movable slide is provided on the bottom surface of the pusher power box 11. The pusher connecting plate 18 moves horizontally in the movable slide.

[0022] A side guide frame 12 is provided on the side of the intermediate sorting plate 20 away from the pusher plate 9. Protective baffles are provided on both sides of the side guide frame 12. An iron metal recycling box 13 is provided below the side guide frame 12 to collect the iron metal adsorbed on the intermediate sorting plate 20.

[0023] A material feeder frame 4 is provided below the vibrating material feeder 1. A vibrating mating seat 3 is provided between the material feeder frame 4 and the vibrating material feeder 1. A shrink guide plate 2 is provided at the discharge end of the vibrating material feeder 1. A vibrating motor 19 is provided below the vibrating material feeder 1 to enable the vibrating material feeder 1 to work effectively.

[0024] The conveyor belt 14 is equipped with a transmission roller 24 and a permanent magnet rotor 25 at both ends. The conveyor belt 14 is also equipped with a transmission motor. One end of the permanent magnet rotor 25 of the conveyor belt 14 is equipped with a protective cover 15 for protection against eddy current separation.

[0025] The protective cover 15 is equipped with a partition baffle 26, with non-metallic bins 27 and non-magnetic metal bins 28 on both sides of the partition baffle 26. The protective cover 15 is equipped with a discharge door 16 to facilitate the removal of sorted materials.

[0026] The working principle of this utility model is as follows: When sorting materials, the materials are supplied to the vibrating cloth 1 so that the materials are supplied evenly downward. A middle sorting plate 20 is set below the discharge end of the vibrating cloth 1. The electromagnet 21 on the middle sorting plate 20 is energized and has strong magnetism, which can attract the ferromagnetic metals in the materials to the middle sorting plate 20. The remaining materials fall onto the conveyor belt 14. A permanent magnet rotor 25 is set at the other end of the conveyor belt 14. Using the eddy current sorting principle, the non-metallic and non-magnetic metals on the conveyor belt 14 are sorted. When cleaning the ferrous metal on the intermediate sorting plate 20, the electric telescopic rod 8 drives the lower baffle 7 to move downwards. The lifting guide rods 29 at both ends of the lower baffle 7 move downwards along the lifting and adjusting groove 6 to ensure the stability of the lower baffle 7's lifting and adjusting. The lower baffle 7 is moved to the lower end of the intermediate sorting plate 20 to block the lower end, de-energizing the electromagnet 21 and starting the pusher motor 17. The pusher motor 17 drives the transmission screw 23 to rotate, and the moving nut seat 22 moves along the transmission screw 23. Since the bottom surface of the pusher power box 11 is provided with a moving groove to limit the pusher connecting plate 18, the pusher plate 9 moves horizontally, effectively collecting the ferrous material on the intermediate sorting plate 20. Since the iron material is removed by contact in this application, the removal effect is better. Although there is a downtime, it can effectively protect the eddy current separator and extend its service life. The intermediate sorting plate 20 is made of magnetic material, and the electromagnet 21 is a MW5 series electromagnet 21. This utility model has a reasonable structural design and is easy to install and use. By setting an intermediate sorting plate 20 between the vibrating feeder 1 and the eddy current separator, and setting an electromagnet 21 below the intermediate sorting plate 20, the material can be processed before being supplied to the conveyor belt 14, absorbing and separating the ferrous metal in the material, thus avoiding the ferrous metal from affecting the sorting process of the eddy current separator. The intermediate sorting plate 20 is equipped with an intermediate removal bracket 5, and a lower baffle 7 that can be raised and lowered is set at the inclined lower end of the intermediate sorting plate 20. The lower baffle 7 blocks the ferrous material from falling onto the conveyor belt 14 during the removal of ferrous material. Then, the ferrous material absorbed on the intermediate sorting plate 20 is pushed into the ferrous metal recycling box 13 by the pusher plate 9 for effective recycling. The pusher plate 9 and the lower baffle 7 are matched in position and shape to ensure the pushing and recycling effect.
