Description
Technical field:
This utility model relates to a kind of grinding technology chats ballast screen subset, particularly relates to a kind of blast-furnace cinder screener
Process and equipment.
Background technology:
The waste residue discharged when blast-furnace cinder is steel plant's blast furnace ironmaking, at present, it is achieved efficiently utilizing of blast-furnace cinder is main
Take after slag shrend by the way of vertical mill grinding obtains slag micropowder.After slag dispatches from the factory, typically through repeatedly having bad luck, pass through vapour
Fortune, shipping, train transport, or multimodal transport is transported to slag micropowder manufacturing enterprise, and slag can be mixed into one unavoidably in the process
The foreign material such as quantitative stone, fragment of brick, woven bag, rope yarn, and the long storage time of slag can cause slag to lump.Stablizing of Vertical Mill
Operation needs into ore grinding slag without big material, foreign material etc., therefore slag needs screened operation to screen out in slag before entering Vertical Mill
Bulk materials and foreign material.
At present, current on market way is: by belt conveyor, slag being delivered to compass screen surface is bar screen surface or grid
The vibrosieve of netted compass screen surface, the foreign material sieve of bulk materials removes by vibrosieve, and the slag meeting particle requirement is fallen to down by compass screen surface
One belt conveyor delivers into vertical mill grinding；As its name suggests, during vibrosieve work, vibrating motor or eccentric motor produce
Raw exciting force, forces sieve nest to drive screen cloth to do lengthwise movement so that it is the material on surface is periodically dished out forward by exciting force.
But the shortcoming of this way is: it is by the impulsive force screening of material with compass screen surface, and for ensureing screening effect, vibrosieve must
Certain amplitude must be ensured, use some granules of netted compass screen surface can be stuck in grid mouth blocking compass screen surface.Woven bag, rope yarn etc. are miscellaneous
Thing, can cause the blocking of bar sieve mesh, and a part of bulk materials can be because repeatedly rolling at its minimum dimension through screen cloth
And enter Vertical Mill.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of reasonable in design, sieve
Divide the blast-furnace cinder sieving technology device effective, maintenance is little and work efficiency is high.
The technical solution of the utility model is:
A kind of blast-furnace cinder sieving technology device, containing feeding belt conveyer, the discharging of described feeding belt conveyer
Mouthful entering cylinder round sifter by charge pipe, slag isolates qualified material and bulk materials and miscellaneous through described cylinder round sifter
Thing, described qualified material enters into mill belt conveyor by qualified material chute, and described bulk materials and foreign material pass through foreign material
Discharge pipe is stacked into storeroom；Described cylinder round sifter includes frame, and described frame is provided with motor and cylinder, and the two leads to
Crossing drive mechanism to connect, described cylinder is provided with screen cloth, slag is entered from one end of described cylinder by described charge pipe, institute
The other end stating cylinder connects with described foreign material discharge pipe.
Described drum-inclined formula arrange, its front end be higher than rear end, the aperture 20mmX20mm of described screen cloth, described cylinder
Inclination angle is 58 °, roll surface speed 55 65m/min of described cylinder.
Arranging lifting blade and quartering hammer in described cylinder, described lifting blade uses spiral design and is fixed on inner wall of rotary drum
On, described quartering hammer uses tup and the structure of hammer stem, and described hammer stem is fixed on the central rotating shaft of described cylinder, described hammer stem
Length be not quite similar.
The beneficial effects of the utility model are:
1, this utility model uses the process unit of belt conveyor+cylinder round sifter+belt conveyor, has both improve sieve
Divide effect, improve again system running rate, also reduce maintenance cost.
2, this utility model relies on the rotation screening materials carrying of cylinder, as long as the angle of inclination of control cylinder and speed of gyration exist
OK range, can obtain good screening effect, the most also be avoided that the blocking to screen cloth of bulk materials and foreign material.
3, arranging lifting blade and quartering hammer in this utility model cylinder, materials overturning and kicking up can be improved by lifting blade
Screening effect, bulk slag can be crushed by quartering hammer, improves the utilization rate of slag.
4, this utility model through screening qualified material pass through into mill belt conveyor enter Vertical Mill, further pulverizing,
Forming continuous print processes process, efficiency is high, laborsaving saves time.
5, this utility model is reasonable in design, screening effect good, maintenance is little and work efficiency is high, and it is applied widely, easily
In promotion and implementation, economic benefit is obvious.
Accompanying drawing illustrates:
Fig. 1 is the use figure of blast-furnace cinder sieving technology device.
Detailed description of the invention:
Embodiment: see Fig. 1, in figure, 1-feeding belt conveyer, 2-cylinder round sifter, 3-foreign material discharge pipe, 4-is qualified
Material chute, 5-enters to grind belt conveyor, 6-charge pipe, 7-foreign material chute.
Blast-furnace cinder sieving technology device contains feeding belt conveyer 1, wherein: the discharging opening of feeding belt conveyer 1
Entering cylinder round sifter 2 by charge pipe 6, slag isolates qualified material and bulk materials and foreign material through cylinder round sifter 2,
