Sheet continuous conveying and magnetic separation device for ferromagnetic material

The invention relates to a sheet continuous conveying and magnetic separation device for a ferromagnetic material. The sheet continuous conveying and magnetic separation device comprises a spherical composite magnetic field separation device and a sheet continuous feeding device which are mounted in a support frame, wherein the spherical composite magnetic field separation device is mounted at the top end of the support frame, and the sheet continuous conveying feeding device is mounted in the support frame; the spherical composite magnetic field separation device comprises four spherical magnetic field generators fixed in a mounting seat, and the mounting seat is fixedly mounted at the top end of the support frame; a central through hole for sheets to be separated to pass through is formed in the middle of the mounting seat, and mounting grooves are formed in the upper surface of the mounting seat around the central through hole; the spherical magnetic field generators are placed in the mounting grooves, each spherical magnetic field generator comprises a spheroid and an annular magnet, the spheroids are placed on the plane of the bottoms of the mounting grooves, one pole of each annual magnet is adsorbed to the surfaces of the corresponding spheroid from the side surface which is away from the central through hole, and the other pole is fixedly mounted relative to the side walls of the mounting grooves through a fixing device; the four spherical magnetic field generators are uniformly distributed on the periphery of the central through hole.
