Abstract
After the continuous improvement, the technical and economical index of the vertical furnace for magnetizing baking generally used at present is improved to some extent, but deficiency still exists. In order to improve the vertical furnace further, a magnetism increasing section is added at the lower part of a reductant ejecting tower. When the ore flows across the section, the FeO reduced is changed into Fe-[3]O-[4]. And the hydrogen gas can be generated; as a result, the rate of products meeting standards can be improved by about 5%; the metal recovery rate can be improved by about 5%; the gain in yield of the ore concentrate is about 25 kg/t; the energy consumption reduced is about 0; the cost reduction in calcining the ore is about 20%.
Description
The utility model belongs to the Industrial Stoves of producing artificial magnet's iron ore.
The present magnetic roasting shaft furnace that generally adopts, basically still belong to plum radical shaft furnace, though this roaster makes production target that improvement significantly be arranged through constantly reforming, but still have a lot of weak points, wherein one of problem is exactly to produce part to cross the reduction ore in roasting process, and product percent of pass is reduced, metal recovery rate reduces, and energy consumption increases.
The purpose of this utility model is improved the substructure of magnetic roasting shaft furnace exactly, increases by one in reducing agent ejection tower bottom and increases the magnetic section, makes the ore of reduction become magnetic Fe when flowing through this section
2O
4Reach the purpose of improving the magnetic roasting shaft furnace production effect.
The utility model by as shown in the figure cloth section (I), bringing-up section (II), reduction section (III), increase magnetic section (IV), quenching ore discharge section (V) is constituted.
Cloth section (I) is made up of distributing device institutes such as (I).
Bringing-up section (II) is made up of exhaust emission tube (2), crossbeam (4), combustion chamber (5), burner (6), bringing-up section burner hearth (3).
Reduction section (III) is made up of reducing agent input pipe (9), reducing agent ejection tower (7), reduction section burner hearth (8).
Increase magnetic section (IV) by gas inlet pipe (11), increase magnetic agent ejection tower (12), increase magnetic section burner hearth (10) and formed.
Quenching ore discharge section (V) is taken out of machine (15) and is formed by ore discharge roller (14), water seal cover (13).
Reducing agent ejection tower is a lateral arrangement, also can vertically arrange.The number of ejection tower is 3-6.
Increase magnetic agent ejection tower for vertically arranging, also can lateral arrangement.The number of ejection tower is 3-6.
Ore discharge roller (14) end face to the height between the reducing agent ejection tower bottom surface is 1500～2500 millimeters (just increasing the height of magnetic section burner hearth).
Increase the every side of magnetic agent ejection tower and have only 1-2 ejection seam.
Effect of the present utility model is significant, and it is about 20% that the cost of roasted ore can reduce, and concentrate output can increase about 25kg/t, and it is about 5% that product percent of pass can improve, and it is about 5% that metal recovery rate can improve, and energy consumption can reduce about 0.04GJ/t.
Accompanying drawing is the drawing in side sectional elevation of magnetic roasting shaft furnace.
Embodiment, long 6000 millimeters of magnetic roasting shaft furnace, wide 2500 millimeters, high 10000 millimeters, increase the magnetic section and highly be 1500 millimeters.Reducing agent ejection tower is a lateral arrangement, totally six, and increase magnetic agent ejection tower and vertically arrange, totally six, each length of reducing agent ejection tower is 1700 millimeters.Wide is 300 millimeters, and height is 350 millimeters, 4 of the every sides of ejection seam, and long 1600 millimeters of ejection seam, the ejection seam is wide 25 millimeters.Increasing each length of magnetic agent ejection tower is 890 millimeters, and wide is 800 millimeters, and height is 900 millimeters, 1 of the every side of ejection seam, and long 800 millimeters of ejection seam, the ejection seam is wide 25 millimeters.
