Description
Technical Field
[0001] The utility model relates to the technical field of nonferrous metal separation, in particular to a nonferrous metal permanent magnet eddy current separator. Background Art
[0002] Eddy current separation is an effective method for recovering nonferrous metals. It offers excellent separation results, strong adaptability, a reliable mechanical structure, lightweight construction, strong (adjustable) repulsive force, high separation efficiency, and a large processing capacity. It can separate some nonferrous metals from electronic waste. In electronic waste recycling lines, it is primarily used to separate nonferrous metals such as copper and aluminum from mixed materials. It can also be promoted and applied in environmental protection fields, particularly in the nonferrous metal recycling industry.
[0003] When electronic waste scraps containing non-magnetic conductive metals (such as lead, copper, zinc, etc.) pass through an alternating magnetic field at a certain speed, induced eddy currents will be generated in these non-magnetic conductive gold scraps. Since the material flow and the magnetic field have a relative motion speed, there is a thrust on the metal pieces and blocks that generate eddy currents. This principle can be used to separate some non-ferrous metals from the mixed material flow. However, the sorting mechanism of the existing permanent magnetic eddy current separator is fixed in position. When the size, shape and irregularity of the metal material changes, the thrust acting on it will also change. The fixed position sorting mechanism is difficult to adapt to metal materials of different specifications. For this reason, a permanent magnetic eddy current separator for non-ferrous metals is proposed for improvement. Utility Model Content

The feeding belt is used to drive the material to move to the sorting belt to provide material for permanent magnet eddy current sorting. A transition plate is set between the feeding belt and the sorting belt to facilitate the movement of material from the feeding belt to the sorting belt.
