Abstract
The invention relates to a blast furnace grain slag filter. A rotating drum shaft is fixed through a bearing on a machine frame; the rotating drum shaft is fixed with a rotating drum; the rotating drum is a rotary filter drum; a support net rack and a wedged filter screen are fixed on the cylindrical face of the rotating drum; a grain slag distributor and a conveyor belt arranged in the rotating drum are fixed on the machine frame; a grain slag pipe is fixed above the grain slag distributor; a bull gear is fixed on the rotating drum shaft; and a pinion gear meshed with the bull gear is driven by a hydraulic motor. The blast furnace grain slag filter has the advantages of simple structure, energy saving and environment friendliness.
Description
Technical field
The present invention relates to a kind of filtration unit of blast furnace granulated slag.
Background technology
The slag temperature that blast furnace ironmaking produces is about 1000 ℃.The high velocity flow cold punching that slag is provided by slag flushing pump in dreg flushing tank becomes grain slag granulation; in this process, can produce large amount temperature at the low-temperature water heating of 95 ℃ of left and right; flushing cinder water is introduced air cooling tower after sedimentation and filtration; flushing cinder again circulates after cooling; but in working cycle, the heat of steam of flushing cinder is not utilized effectively; but by cooling tower, amount of heat is diffused in atmosphere by evaporation; both caused the waste of the energy; again environment has been caused to thermal pollution, part water vapor is dispersed into and in atmosphere, has also consumed water resources.After flushing cinder water spray flushing cinder, the part water vapor of generation is discharged from chimney, and hot water, after sedimentation and filtration, carries out cooling by cooling tower, and flushing cinder again circulates after cooling.What blast furnace slag quenching water adopted is turbid circulating water, has saved to a certain extent industrial new water, however the outer row of a large amount of steam and heat loss, also caused certain waste, and in the steam that flushing cinder produces, contain sulfurous gas, hydrogen sulfide, be discharged into and in atmosphere, form acid rain, contaminate environment.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of blast furnace slag filter, it is simple in structure, energy-conservation, environmental protection.
The present invention solves the technical scheme that its technical problem takes: in frame by the fixing rotary drum axle of bearing, rotary drum axle and rotary drum are fixed, rotary drum is rotating filter cartridge, fixed support rack and wedge shape filter screen on the cylindrical surface of rotary drum, in rotary drum, have grain slag divider and carrier strip in the frame of being fixed on, the top of grain slag divider is fixed with grain slag pipe; Fixing master wheel on described rotary drum axle, the pinion(gear) being engaged with is by fluid motor-driven.
The present invention is simple in structure, energy-conservation, environmental protection.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is front view of the present invention;
Fig. 2 is left view of the present invention.
Embodiment
As shown in Figure 1, 2, in frame 6 by the fixing rotary drum axle 5 of bearing, rotary drum axle 5 is fixing with rotary drum 1, rotary drum 1 is rotating filter cartridge, fixed support rack and wedge shape filter screen on the cylindrical surface of rotary drum 1, in rotary drum 1, have grain slag divider 2 and carrier strip 8 in frame of being fixed on 6, the top of grain slag divider 2 is fixed with grain slag pipe 7; Fixing master wheel 4 on described rotary drum axle 5, the pinion(gear) 3 being engaged with is by fluid motor-driven.
Fixedly pressurized air and high pressure water jet pipe (not shown in FIG.) on one side frame 6 of described rotary drum 1, to rotary drum 1 continuous wash, to remove the grain slag particle that adheres to and embed filter screen.
After blast furnace slag is separated with molten iron; through slag runner, enter slag granulating district, the high velocity flow of grain slag Punched box ejection makes slag water quenching granulation cooling, after the further granulation of granulated slag groove and buffering; in the grain slag divider 2 flowing in rotary drum 1 through grain slag pipe 7, then evenly flow in rotary drum 1 strainer.When forwarding the rotary drum first half to, slag is fallen on the carrier strip stretching in rotary drum, through this belt with distribute Belt Conveying to grain slag storage place, finally by truck, is transported.
Claims (2)
