REGENERATION AND RECYCLING EQUIPMENT FOR FERROUS METAL

摘要

The present invention discloses ferrous metal recycling and regeneration equipment. In the equipment, the recycled ferrous metal is stored in recycled material storage tank, and in acid dissolving tank, acidic solution is added, then ferrous metal is poured in to remove non-ferrous metal impurity, then impurity is filtered through first filtering device, ferrous metal solution is then led to mixing tank, then in mixing tank, element phosphorus (P) is added so that P and Fe can compound into Ferric Phosphate (FePO₄.nH2O, where n can be 2 or 4), then Ferric Phosphate precipitated solution is injected into second filtering device, then through centrifugal force, Ferric Phosphate is separated in different grades, then solid Ferric Phosphate will be obtained through flash dryer from the separated Ferric Phosphate. Therefore, through improved process equipment, the recycling and reproduction of ferrous metal is focused, and the process can be simplified to reduce the defective rate, subsequently, the cost is greatly reduced.
