Description
Technical field：
The utility model belongs to granular material storage and conveying technology field, more particularly to a kind of big barrel dliameter cylindrical reinforcing steel
Concrete silo blockage-clearing device.
Background technology：
The ore dressing plant fine coal transfer station in current all kinds of mines, raw coal loading station, granular material staithe etc., are designed with storing up
Material stock storehouse, for adjusting production procedure, distribution material is selected in path and adjusted into ore dressing amount, balanced ore dressing process.It is current large-scale
Enterprise's dosage it is more be the flat four outlets armored concrete feed bin of big barrel dliameter cylinder, barrel dliameter generally reaches 20m or so.
After material enters feed bin, due to the moisture content of material, the physical factor such as lumpiness and surface configuration is different, causes thing
Frictional force between material and bulkhead increases, and material can not lean on the gravity of itself to overcome frictional force to slip out outside feed bin, cause material
Viscous wall blocks.Again because material water ratio is higher, and material is very thin, and the surface area sum of material particles is very big in unit volume,
When moisture content reaches 8%, cohesive force reaches peak.When moisture content is more than 8% or during less than 8%, cohesive force all under
Drop.After cohesive force increase, the counterfort of scaffold can be formed around discharging opening and at bulkhead especially to big barrel dliameter feed bin, these
Counterfort occupies the dischargeable capacity of feed bin.The function of feed bin cannot be played effectively.Currently used feed bin Method of blockage removal is people
In work tripping in feed bin, hold long rod and disclose material, or blow dredging up with dynamite, when there is personal injury and feed bin to damage, peace be present
