1results about How to "Increase iron content" patented technology

The utility model provides a kind of sulphuric acid residue efficient utilization sintering equipment, including sintering furnace, the side of sintering furnace is provided with screening cylinder, spiral disc is fixedly connected in the screening cylinder.The utility model has the advantages that: the inertia of sulphuric acid residue with higher iron element content is stronger, it moves to discharge plate over drop hole, and rolls to screening box along discharge plate.Start motor drives magnetic roller to rotate, sulphuric acid residue in screening box falls on magnetic roller under the action of inertia, sulphuric acid residue with more iron content relative to its mass is adsorbed and driven to rotate by magnetic roller, sulphuric acid residue with less iron content relative to its mass flows along magnetic roller to enter discharge cylinder at through hole, so that the magnetic separation of sulphuric acid residue is realized.Sulphuric acid residue with higher iron element content enters sintering furnace through material passage, and completes ironmaking work with other ironmaking raw materials.Sulphuric acid residue is automatically screened, and two screening procedures are passed, and ironmaking raw material has higher iron element content, which is conducive to improving ironmaking quality.
