Embodiment Construction

[0009] The reference signs shown in the figure are: outer drum 1, outer drum rotating shaft 11, outer drum driving wheel 12, inner drum 2, inner drum rotating shaft 21, inner drum driving wheel 22, magnetic unit 23, rack 3, blanking Port 4, feed port 5, inner ring 51, outer ring 52.

[0010] In the embodiment of the present invention, during the working process, the inner drum 2 and the outer drum 1 rotate in the opposite direction or in the same direction at different speeds, thereby generating an alternating magnetic field outside the outer drum, and bulk materials fall from the discharge port 4 to the outer drum of the outer drum. On the cone surface, non-metallic materials are thrown into the inner ring 51 of the material inlet 5 under the action of the centrifugal force and gravity of the outer drum 1, and the non-magnetic metal in the material flow bounces to the outer ring of the material inlet 5 under the action of the eddy current 52, so as to achieve the purpose of s...

Abstract

The invention relates to a magnetic separation device, in detail is a bow wave type magnetic separation machine. The magnetic separation machine includes an outer rolling drum with the inner and outer wall being conical surfaces, the outer rolling drum is the non-magnetic and non-metallic material; an inner rolling drum is arranged in the outer rolling drum, the inner rolling drum has a male cone near the inner wall of the outer rolling drum, magnetic units with opposite polarities are alternatively disposed on the male cone of the inner rolling drum; the inner and outer rolling drum have the same vertical rotary axis and are driven by different rotor axes respectively; blanking ports are arranged at the upper part of the inner and outer rolling drum, and annular material-receiving ports are arranged on the periphery at the lower part of the inner and outer rolling drum. The invention can improve the selection effect of non-magnetic metal energy.

Description

technical field [0001] The invention relates to magnetic separation equipment, in particular to an eddy current magnetic separator. Background technique [0002] The working principle of the eddy current magnetic separation equipment is that magnetic materials with opposite polarities are alternately arranged on the rotating drum. When the material flow containing non-ferrous metals (such as aluminum, copper, zinc, etc.) passes through the drum at a certain speed, due to The alternating magnetic field generated by the rotating drum induces eddy currents in the non-ferrous metals. Since the material flow and the magnetic field have a relative movement speed, a thrust is formed on the metal conductor that generates the eddy current, so the non-ferrous metal can be separated from the material flow to achieve the purpose of separating the non-ferrous metal. In the traditional eddy current magnetic separation equipment, the drums are generally arranged horizontally, the alternat...
