Technical field
The utility model relates to technical field of ferrous metallurgy, particularly a kind of molten iron agitator.
Background technology
In metallurgy industry, the stirring desulphurization method is a kind of External Desulfurization Technique From Melten Iron commonly used, this sulfur method is that agitator with fire-resistant outer lining immerses in the hot-metal bottle and is rotated stirring, make molten iron produce vortex, desulfurizing agent through weighing joins the molten iron surface by dispenser, and be involved in the molten iron by vortex, with the high temperature liquid iron hybrid reaction, reach the purpose of desulfurization.
Agitator is the vitals in the desulfurizer, and agitator of the prior art is comprised of rotating shaft and cross blade.The agitator core is that the metal material casting forms, and working lining is the integrated poured moulding of castable refractory.When stirring desulphurization, general agitator speed is 120d/min, and torque is 820kgfm, thereby molten iron obtained good desulfurization dynamic condition, and desulfurizing agent can be fully utilized, and has improved desulfuration efficiency.
Desulfur agitator of the prior art exists multiple, below content will enumerate a few class desulfur agitators.
Wherein a kind of from improving the stirring intensity angle of agitator, carried out the research of the agitator of different structure, be intended to improve rate of sulphur expulsion and reduce sorbent consumption by shortening the mixing time of single desulfurization, reach the purpose that improves agitator service life and desulfuration efficiency.Another kind is digester bottom blowing nitrogen method, is blown into high pressure nitrogen by the air brick that is arranged at the bottom of the tank in tank, promotes the come-up of desulfurizing slag from molten iron, reaches the purpose that improves rate of sulphur expulsion and hot metal purifying degree.Another untouchablely is designed to that front concave arc surface, back iron face are designed to concave and downward convex multistage arcwall face, lateral layout is served as reasons down and upper outside inclined plane by the paddle of agitator is met, by the polymorphic structure paddle, reach and improve agitator the stirring of desulfurizing agent is entrainmented intensity, improved the purpose of desulfurization kinetics condition.
By above-mentioned several mechanical agitation desulfuration methods as seen, the means of improving the desulfurization kinetics condition are to promote mixing of molten iron and desulfurizing agent by the whirlpool that agitator rotation forms.
Yet, agitator of the prior art, concentric so that even flow field has but been ignored the radial dispersion problem of the desulfurizing agent that is involved in the molten iron with hot-metal bottle in whipping process, and caused in the molten iron desulfurizing agent discrete areas little, desulfurized effect has been brought adverse effect.
Therefore, how to solve the less problem of desulfurizing agent discrete areas in the molten iron, become those skilled in the art's important technological problems to be solved.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of molten iron agitator, its can the Effective Raise molten iron in the area of desulfurizing agent discrete areas, and then improved desulfurized effect.
The molten iron agitator that the utility model provides comprises that main shaft, at least two are connected in the countershaft of described main shaft, drive main drive that described main shaft rotates, are arranged at rotationally the stirring vane of each described countershaft and drive the assistant drive device that each described stirring vane rotates respectively.
Preferably, the quantity of described countershaft is two, and is arranged at the stirring opposite direction of two stirring vanes of two described countershafts.
Preferably, the quantity of described countershaft is two, and it is identical to be arranged at the stirring direction of two stirring vanes of two described countershafts.
Preferably, described main drive and described assistant drive device are motor.
Preferably, the cross sectional shape of described stirring vane is " ten " font.
Preferably, the surface of described main shaft, described countershaft and described stirring vane is equipped with high-temperature-resistant layer.
The molten iron agitator that the utility model provides comprises that main shaft, at least two are connected in the countershaft of described main shaft, drive main drive that described main shaft rotates, are arranged at rotationally the stirring vane of each described countershaft and drive the assistant drive device that each described stirring vane rotates respectively.So arrange, the molten iron agitator that the utility model provides, when carrying out the stirring of molten iron, can drive main shaft by main drive rotates, and then the drive countershaft rotates centered by main shaft, because countershaft is a plurality of, so a plurality of stirring vanes are under the driving effect of separately assistant drive device, not only can carry out rotation, can also revolve round the sun centered by main shaft, so molten iron is under the agitaion of a plurality of stirring vanes, and it is larger that it stirs area, and molten iron and molten iron clash into mutually, can so that desulfurizing agent effectively disperseed.
