Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board recycling equipment, and in particular relates to a metal separation device for waste circuit boards. Background Technology

[0002] With the rapid updates and iterations of electronic products, the recycling of waste circuit boards has become an important part of resource recycling. Circuit boards contain a variety of valuable metals, such as copper, iron, and aluminum. The separation of ferrous metals is one of the key steps in the recycling process, and separation equipment is used to separate the metals from the circuit boards.

[0003] Existing separation equipment often employs magnetic separation when separating ferromagnetic metals from circuit boards. This method utilizes the principle of magnetic adsorption, using permanent magnets or electromagnetic devices to separate ferromagnetic materials from mixed fragments. Typically, magnetic plates are vertically positioned below the tearing rollers used to rip the circuit boards for sorting. The broken circuit board fragments usually fall freely through the magnetic zone. Due to the high falling speed of the fragments, the ferromagnetic metals cannot be fully adsorbed during their brief passage through the magnetic field, causing some ferromagnetic materials to fall along with the non-metallic fragments, affecting the separation efficiency. While some equipment attempts to improve the adsorption effect by increasing the area of ​​the magnetic plates or adjusting the tilt angle, it remains difficult to effectively control the falling speed of the fragments and the contact time with the magnetic field. This problem reduces separation efficiency, often requiring multiple sorting cycles to achieve the desired metal recovery rate, increasing energy consumption and reducing overall processing efficiency.

[0004] To address these issues, we provide a waste circuit board metal separation device. Utility Model Content

The servo motor 41 drives the frame 42 to rotate half a turn clockwise. The non-magnetic materials that are not attracted fall from the frame 42 and are guided by the guide block 11 and discharged from the discharge port 12. The fragments discharged from the discharge port 12 can enter the next process to separate the non-magnetic metals.

[0033] The second cylinder 9 drives the second guide plate 10 to move, and the servo motor 41 reverses, causing the frame 42 to align with the second guide plate 10. The first cylinder 54 pushes the baffle 55 to open the frame 42, and at the same time, the drive motor 57 starts, driving the threaded rod 58 to rotate, causing the threaded sleeve 59 and the connecting rod 510 to move, thereby driving the scraper 52 to scrape off the ferrous metals adsorbed on the magnetic plate 43. The scraped ferrous metals are guided by the fixed plate 44, the second guide plate 10 and the first guide plate 7, and discharged from the outlet 6, completing the recycling. Through the above design, the problem of insufficient adsorption caused by the excessive speed of falling fragments in traditional separation equipment is effectively solved, and the metal separation efficiency and recovery rate are significantly improved.
