Description
Technical field
The utility model relates to ironmaking equipment field more particularly to a kind of works for preventing lateritic nickel ore from gluing storehouse and mixing unevenness
Skill equipment.
Background technique
It needs in ironmaking using lateritic nickel ore, is generally all directly in sintering Primary batching system storehouse internal reference in use
It is serious by sizing when feed bin but since the moisture of lateritic nickel ore is up between 30% -40% with ingredient, often glue
Storehouse putty, fracture phenomenon, and by mixing machine mixing when occur it is agglomerating mix irregular phenomenon, influence the stabilization of mixture composition, no
Conducive to the stabilization of nickel, chromium composition in sinter, and due to the influence of blanking difficulty, the proportional quantity of lateritic nickel ore is restricted,
To influence product quality.
Utility model content
The technical problem to be solved by the utility model is to provide structures to be simple and convenient to operate, at low cost and prevent laterite
Nickel minerals glues the process equipment in storehouse and mixing unevenness.
The utility model is to be achieved by the following technical programs:
A kind of process equipment for preventing lateritic nickel ore from gluing storehouse and mixing unevenness comprising hot-blast stove, drum drier and cloth
Bag dust collector, the hot-blast stove include burner hearth, the mixing chamber in burner hearth, and the hot-blast stove is connected with blast furnace gas pipeline
And it is equipped with mixing chamber air outlet, and lateritic nickel ore import is equipped at the top of the drum drier, bottom is exported equipped with lateritic nickel ore, and two
End is respectively equipped with drying machine hot wind inlet and drying machine hot-blast outlet, and the bag filter is equipped with deduster exhaust gas inlet and removes
Dirt device waste gas outlet is equipped with exhaust fan, the mixing chamber air outlet and drying machine heat at the bag filter waste gas outlet
Wind inlet is connected, and drying machine hot-blast outlet is connected with deduster exhaust gas inlet, the drum drier lateritic nickel ore outlet
It is connected with sintering Primary batching system storehouse.
Further, temperature controller is fixedly installed in the drum drier.
The beneficial effects of the utility model
Using a kind of process equipment for preventing lateritic nickel ore from gluing storehouse and mixing unevenness provided by the invention comprising hot wind
Furnace, drum drier and bag filter, the hot-blast stove include burner hearth, the mixing chamber in burner hearth, shown hot-blast stove with
Blast furnace gas pipeline is connected and is equipped with mixing chamber air outlet, in this way, hot-blast stove is heated using blast furnace gas, blast furnace
Coal gas is recycled, and advantageously reduces cost, and protects environment, when drying, first by blast furnace gas ignition, in hot-blast stove
Air heated, opening the exhaust fan of bag filter will through drum drier from the extraction of the mixing chamber of hot-blast stove by hot wind
After drum drier heating, lateritic nickel ore is placed into, lateritic nickel ore is dried, exhaust gas is met from bag filter dedusting
It is drained into atmosphere after discharge standard from deduster waste gas outlet, is conducive to environmental protection.
Temperature controller is fixedly installed in drum drier, the control terminal of temperature controller is connected with exhaust fan, when
Temperature controller detects that temperature is more than predetermined temperature, will control exhaust fan and stop working, prevent the temperature of drum drier
It is excessively high.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view；
1. gas piping in figure, 2. hot-blast stoves, 3. burner hearths, 4. mixing chambers, 5. drum driers, 6. lateritic nickel ore imports,
7. lateritic nickel ore exports, 8. bag filters, 9. exhaust fans, 10. Primary batching system storehouses, 11. temperature controllers.
Specific embodiment
It is a kind of prevent lateritic nickel ore glue storehouse and mixing unevenness process equipment comprising hot-blast stove 2, drum drier 5 and
Bag filter 8, the hot-blast stove include burner hearth 3, the mixing chamber 4 in burner hearth, the hot-blast stove and blast furnace gas pipeline 1
It is connected and is equipped with mixing chamber air outlet, lateritic nickel ore import 6 is equipped at the top of the drum drier, bottom is equipped with lateritic nickel ore
