[0002] A large amount of gravity dust is produced during the blast furnace ironmaking process. It is mainly composed of magnetite, hematite, coke powder, calcium ferrite and other minerals. Other metal minerals exist in the form of oxides. The iron in blast furnace gravity dust is a recyclable resource.

Therefore, we propose a blast furnace dust ash recycling device to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This device uses an electromagnetic plate inside the processing box, and cooperates with a double-headed motor and two vibration blocks to drive the electromagnetic plate to vibrate up and down quickly, which will vibrate and sort the dust. The magnetic force generated by the electromagnetic plate will cause the metal in the dust to be adsorbed on the surface of the electromagnetic plate. The dust generated by the sorting can be discharged through the cooperation of the air deflector, the suction fan and the air suction port, so that the blast furnace dust can be continuously sorted. By disconnecting the electromagnetic plate from the power supply, the magnetic force of the electromagnetic plate can be eliminated, and the metal above the electromagnetic plate will slide to the left, which is convenient for collecting the sorted metal.
