[0015] Referring to Figures 1-4 , the embodiment is a wet magnetic separator, comprising a rack 1, the rack 1 is provided with an ore pulp tank 2, the ore pulp tank 2 is fixedly connected with the rack 1, the ore pulp tank 2 is provided with a concentrate outlet 10 and a tailing outlet 9, the ore pulp tank 2 is provided with a rotating drum 4, the rotating drum 4 is provided with a support shaft 3 at the center, the support shaft 3 passes through the rotating drum 4 at both ends and is fixedly connected with the rack 1, a group of bearings are arranged between both ends of the rotating drum 4 and the support shaft 3, the part of the support shaft 3 located in the rotating drum 4 is provided with a mounting frame and a support frame, the mounting frame is provided with a driving motor 6, the driving motor 6 is in transmission connection with the rotating drum 4, the bottom end of the support frame is provided with permanent magnets, the permanent magnets are uniformly arranged in an arc shape with the support shaft 3 as the center, and a certain spacing is arranged between the outer wall surface of the permanent magnets and the inner wall of the rotating drum 4.

[0016] Further, the rack 1 is provided with an overflow tank 5 at the inlet of the ore pulp tank 2, and the outlet of the overflow tank 5 is in communication with the ore pulp tank 2.

[0017] Further, the permanent magnets are composed of multiple pieces, and the thickness of the permanent magnets gradually decreases from the tailing outlet 9 to the concentrate outlet 10, so that the magnetic attraction force at the concentrate outlet 10 gradually decreases, which is beneficial to the concentrate to separate from the rotating drum 4 and be thrown to the concentrate outlet 10.

[0018] Further, the ore pulp tank 2 is provided with a falling section 21, a detour section 22 and a rising section 23, the tailing outlet 9 is arranged at the end of the detour section 22, the concentrate outlet 10 is arranged at the end of the rising section 23, and a part of the permanent magnets corresponds to the detour section 22 and the other part corresponds to the rising section 23.

[0019] The working principle of the utility model is as follows: the ore pulp enters the inlet of the overflow launder 5 and is blocked by the baffle in the overflow launder 5 and then overflows into the ore pulp tank 2, the ore pulp enters the detour section 22 after the descending section 21, the rotating direction of the rotating drum 4 is opposite to the flowing direction of the detour section 22, the permanent magnet in the rotating drum 4 adsorbs the concentrate in the ore pulp to the outer surface of the rotating drum 4, and the tailings flow to the tailings outlet 9 along the detour section 22 to the end; the concentrate is adsorbed on the rotating drum 4 and rotates to the concentrate outlet 10, when the concentrate rotates to the concentrate outlet 10, the concentrate is thrown to the concentrate outlet 10 due to losing the suction of the permanent magnet.
