Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0022] Such as Figure 1 to Figure 6 As shown, an electromagnetic induction metal screening equipment includes a frame 1, and also includes a conveyor belt 2, idler rollers 3 and conductive slide rails 5, idler rollers 3 and guide rails are respectively arranged on both sides of the frame 1, and the conveyor belt 2 It is a chain plate conveyor belt. The conveyor belt 2 is tensioned on the frame through the idler roller 3 and the guide rail. The rotation of the idler roller 3 drives the conveyor belt 2 to run around the guide rail and the idler roller 3 on the frame 1. The right end of the conveyor belt 2 is The idler 3, the idler 3 is a cylinder, and the two ends of the idler 3 are provided with gears; the left end of the conveyor belt 2 is a guide rail, and the guide rail is "匚" shaped, and a conductive slide rail 5 is arranged inside the guide rail...

Abstract

The invention relates to the field of nonferrous metal recovery, in particular to the recycling of metal after the disassembly and breakage of waste and old articles, and specifically relates to electromagnetic induction metal screening equipment. The electromagnetic induction metal screening equipment disclosed by the invention adopts a conveying classified screening mode, and achieves the targeted screening of non-ferrous metals easy to magnetize, non-ferrous metals not easy to magnetize and other non-metallic materials by adopting the eddy current electromagnetic induction technology. The equipment employs a special chain plate conveying device, completes the screening of materials in the conveying process, automatically classifies the materials into different material piles in the falling process, and completes the screening work of different kinds of materials, thereby greatly improving the screening efficiency. Moreover, the metals not prone to being magnetized are separated, theseparation kinds are increased, and the later sorting procedure is reduced.

Description

technical field [0001] The invention relates to the field of non-ferrous metal recycling, in particular to metal recycling after dismantling and crushing of waste products, and in particular to electromagnetic induction metal screening equipment. Background technique [0002] Eddy current separation (ECS) is a sorting technology that utilizes the different conductivity of materials. Its sorting principle is based on two important physical phenomena: an alternating magnetic field that changes with time is always accompanied by an alternating magnetic field. A changing electric field (law of electromagnetic induction); a current-carrying conductor produces a magnetic field (Biot-Savart's law). The principle of eddy current separation: when working, a high-frequency alternating strong magnetic field is generated on the surface of the sorting magnetic roller. When the conductive non-ferrous metal passes through the magnetic field, an eddy current will be induced in the non-ferro...
