The invention provides an eddy current sorting device. The eddy current sorting device comprises a magnetic conductive device, a magnetic winding roller, a first conveying device, a second conveying device, and a negative pressure adsorption device; the magnetic conductive device and the magnetic winding roller are arranged on the first conveying device; the magnetic conductive device extends for a certain distance in the conveying direction of the first conveying device; the magnetic conductive device is connected with the magnetic winding roller in a magnetic conductive mode; eddy current can be generated in metal materials passing through the magnetic conductive device through alternating current generated by rotation of the magnetic winding roller; the second conveying device is arranged above the first conveying device, corresponds to the magnetic conductive device, and is connected to a first accommodating part for receiving the metal materials; and the negative pressure adsorption device is connected with the second conveying device so as to adsorb the metal materials bounced under the driving of the eddy current to the second conveying device. By applying the above technical schemes, the sorting efficiency of the eddy current sorting device can be improved.
Description
technical field [0001] The invention relates to an eddy current separation device. Background technique [0002] At present, domestic eddy current separators can be divided into concentric and eccentric eddy current separators according to different structures. Concentric and eccentric eddy current separators mainly use the conductivity of each material. The separation principle is to use the magnetic system drum composed of magnets to rotate at high speed, cut the magnetic induction line during the rotation, and generate an alternating magnetic field. When a metal with electrical conductivity passes through a magnetic field, an eddy current will be induced in the metal. The eddy current itself will generate an alternating magnetic field and is opposite to the direction of the magnetic field generated by the rotation of the magnetic system drum, so that non-ferrous metals (such as aluminum, copper, etc.) etc.) will jump out at 90 degrees along its conveying direction due to...
