Description
Technical field
The utility model relates to a kind of bin device, the special anti-segregation feed bin of especially a kind of standard bag packaging iron powder.
Background technology
At present, the production of partial metallurgy reduced iron powder, conventionally adopt by raw material, deoxidation compound pack into tank body laggard enter tunnel Kiln once reduce and generate freak oil sponge iron, according to the reduced iron powder variety classes that will produce, the powder that sponge iron is broken into corresponding granularity enters reduction furnace and carries out secondary reduction.With abundant decarburization, deoxidation, desulfurization, improve iron level, eliminate work hardening and improve its plasticity, improve compression performance, after secondary reduction, carry out fragmentation, screening, magnetic separation, enter after closing batch behind package storehouse and pack and dispatch from the factory.
In actual production operational process, be stored in packaging feed bin close batch powder in the time of mixing machine blowing owing to affected by Van der Waals force between gravity factor and powder, relatively more relatively fine grained blanking velocity is fast for coarse particle, while entering packaging feed bin through carrying materials device, relatively coarse particle is preferentially gathered in warehouse bottom, is massif shape along with increasing of reduced powder, and relatively coarse particle is gathered in warehouse surrounding, relatively fine grained is gathered in centre, has formed particle segregation phenomenon.
When packaging standard bag, the reduced powder of emitting from packaging feed bin is also because of Van der Waals force impact between gravity factor and powder, make that the standard bag reduced powder of batch packaging occurs between bag and bag, the uneven and generation segregation of the particle size distribution of the reduced powder of early stage packaging and later stage packaging, directly affect compact density and the sintering character of compacted products.
At present in order to ensure the iron particle size distributing homogeneity of compacting material powder, adopt of some product enterprises realized the measures such as iron powder premixed or buying segregation-free premix powder more, weak point is: the one, and iron powder can ensure through premixed the homogeneity that iron particle size distributes, but may cause the rising of enterprise's productive costs; The 2nd, segregation-free premix powder price is much higher compared with reduced iron powder, must cause the increase of productive costs.At present, there is not yet the report for the special anti-segregation feed bin of standard bag packaging iron powder.
Chinese patent ZL200920042262, ZL201210519076, ZL201220159817 all disclose a kind of anti-segregation feed bin, and three disclosed technical schemes of patent are substantially the same, but are all not suitable for partial metallurgy reduced iron powder technology.
