Abstract
Method for removing iron before updraft type Slag super-fine powder mill, belong to field of metallurgy discarded object recycling, slag is after first upper-suction magnetic separator carries out first time magnetic separation, effective realization first time slag, iron are separated, and make the two stratiform materials that the formation of the slag after first time magnetic separation upper strata is abrasive grit, lower floor is slag; The termination that two stratiform materials after first time magnetic separation arrive belt conveyor starts freely falling body, two stratiform material second time are sorted, namely by second upper-suction magnetic separator, the abrasive grit being positioned at upper strata after first time magnetic separation is upwards picked up, and the slag being positioned at lower floor drops downwards.Slag after magnetic separation of the present invention, produces Slag super-fine powder through vertical roller grinder, can make the grinding roller life of resistance to material more than 10 days, at least can increase by 30 days running times of Vertical Mill the whole year, not only save cost of equipment maintenance, and increase annual production, create great economic benefit.
Description
Technical field
The invention belongs to field of metallurgy discarded object recycling.
Background technology
Along with increasing rapidly of iron and steel output, its metallurgical slag total amount also increases year by year, except slag, amount of slag significantly increase.In recent years, country actively pushes forward energy-saving and emission-reduction and recycles, to achieve the sustainable development of enterprise.Therefore, the process of slag and effective Utilizing question urgently to be resolved hurrily.Vertical roller grinder produce Slag super-fine powder because it is efficient, low consumption, the pollution-free first-selection becoming the deep processing of Taiyuan Iron and Steel Co. slag.
Current tupe adopts belt tramp iron separator as magnetic material sorter; to be comprised by slag due to the large portion of abrasive grit or extrude; abrasive grit is selected by belt tramp iron separator; thus make a large amount of slag abrasive grit be brought in mill; cause grinding roller of vertical mill, abrasive disk abrasion serious; the bimester of being forced to per, maintenance down once, overhauls 7 ~ 10 days at every turn.
Summary of the invention
The present invention is intended to solve deironing before mill in Slag super-fine powder production process, to improve the service life of the resistance to material of Vertical Mill, improves Vertical Mill year Homes Using TV.
Slag of the present invention, after first upper-suction magnetic separator carries out first time magnetic separation, effectively realizes first time slag, iron is separated, and makes the slag after first time magnetic separation form the two stratiform materials that upper strata is abrasive grit, lower floor is slag;
The termination that two stratiform materials after first time magnetic separation arrive belt conveyor starts freely falling body, two stratiform material second time are sorted, namely by second upper-suction magnetic separator, the abrasive grit being positioned at upper strata after first time magnetic separation is upwards picked up, and the slag being positioned at lower floor drops downwards.
The matching used equipment of the present invention has two belt conveyors, and one of them is high-order belt conveyor, and another is low level belt conveyor; Arranging a upper-suction magnetic separator between the great wheel of high-order belt conveyor and the tail wheel of low level belt conveyor, is namely first time magnetic separator;
The upper left side of the great wheel of low level belt conveyor arranges second upper-suction magnetic separator; Second upper-suction magnetic separator side arranges scrap iron storehouse.
Slag after magnetic separation of the present invention; Slag super-fine powder is produced through vertical roller grinder; the grinding roller life of resistance to material can be made more than 10 days; namely every 70 days maintenance down once; at least can increase by 30 days running times of Vertical Mill the whole year; not only save cost of equipment maintenance, and increase annual production, create great economic benefit.
Superfine powder increases by 30 day working time by 60 yuan of profit years per ton, creates economic worth more than 5,000,000 yuan.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
In figure, 1, the belt great wheel of high-level leather belt conveyor, 2, suspender, 3, baffle plate, 4,1# upper-suction magnetic separator, 5, the belt great wheel of low level belt conveyor, 6, slag, 7,2# upper-suction magnetic separator, 8, iron, 9, Tie Ku, 10, blade.
Detailed description of the invention
Technological process of the present invention is:
Distributing baffle 3 and 1# upper-suction magnetic separator 4 is set up between belt great wheel 1 bottom and the belt tail wheel of low level belt conveyor of high-level leather belt conveyor; Distributing baffle 3 is arranged on suspender 2; The suspender of 1# upper-suction magnetic separator mounting hanger, suspender arranges bolt can the height of controllable register 3 position;
In order to distributing baffle position can be made can to carry out flexible modulation according to upper doses, avoid the slag dropping on baffle surface to splash, suspender is set to adjustable;
Distributing baffle: movable adjustable, can, according to slag iron-holder controllable register angle, make slag drop on 1# upper-suction magnetic separator 4 with optimum thickness, flow velocity and loose shape;
In order to increase slag and magnetic separator contact area, increase magnetic separation ability; The cylinder of 1# upper-suction magnetic separator 4 and 2# upper-suction magnetic separator 7 sets up gusset;
Prevent slag adverse current, effectively segmentation slag makes slag content substantially constant between adjacent blade 10, increases the contact area of slag and magnetic separator simultaneously, increases magnetic separation ability, the cylinder on two upper-suction magnetic separators sets up blade;
Slag effectively realizes slag after the sorting of 1# upper-suction magnetic separator, iron is separated, and the slag after this magnetic separation forms the two stratiform materials that a kind of top is abrasive grit, bottom is slag.
In the oblique upper of the belt great wheel 5 of low level belt conveyor, 2# upper-suction magnetic separator is installed;
The belt great wheel 5 arriving low level belt conveyor through the material of first step sorting starts freely falling body, material the second loosening shape, and now 2# upper-suction magnetic separator both can the abrasive grit of magnetic separation first step sorting, again can to the magnetic separation again of the slag of the second loosening.Namely by 2# upper-suction magnetic separator, the abrasive grit being positioned at upper strata after first time magnetic separation is upwards picked up, and the slag being positioned at lower floor drops downwards.
