Iron ore refinement device

The invention discloses an iron ore refinement device. The iron ore refinement device comprises a machine body; the top end of the machine body is provided with a feed inlet; the bottom end of the machine body is provided with a feed outlet; in the machine body, from the feed inlet to the feed outlet, a high-temperature heating segment, a natural cooling segment, and a strong cooling segment which are communicated are arranged successively; the external of the high-temperature heating segment is provided with a heating device; and the external of the strong cooling segment is provided with a cooling device. In working processes, iron ore mixed with carbon is delivered into the machine body via the feed inlet; and then the mixed material is delivered into the high-temperature heating segment so as to realize ore refinement via corresponding reaction; a material obtained via refinement is delivered through the natural cooling segment and the strong cooling segment successively to be cooled to an appropriate temperature, and then is discharged from the machine body via the feed outlet; the whole refinement process of the iron ore refinement device is simple and high in efficiency.
