Description
Technical field
The utility model relates to the inner granular material discharging of a kind of silo, feedway.
Background technology
Reserves are big because the heavy steel plate silo has, reduced investment, outstanding advantage that construction is fast, are used widely in powder materials such as cement, slag micropowder, fly ash store.
The material conveying method of existing conventional libraries body has unicity, and common has:
First kind of main strength derives from plenum box, limitation (physical property) as cylindrical shell and powder grain material, by the material in the last cylindrical shell of this kind carrying method is a taper shape, cause result of use out of reach expection requirement in the cylindrical shell, cause energy dissipation (electric power, strength and turnover consumption power are excessive).
Second kind is existing heavy steel plate storehouse, and existing steel silo diameter is excessive, and is single-point discharging (center discharging) in carrying gallery, and diameter is excessive to be to cause the corner to be not fully utilized, and can occur and first kind of similar problem.This strength derives from air inflator system (being commonly called as the fluidisation pipe), in case overstocking time course, the corner material can cause the fluidisation pipe to be the state of killing, the effect of out of reach gas release, afterwards feel weak as power, the interior material of the cylindrical shell that accumulates over a long period will accumulate year in year out, the scaffolding effect occurs, the turnover result of use will significantly reduce.
The third also is existing heavy steel plate storehouse, and this kind mode of movement is nonstandard plenum box, and the problem of appearance is almost similar with second kind.
According to traditional ferro-concrete tradition cylindrical shell, prolong tube structures such as sharp Pu cylindrical shell with Germany technology, novel large steel silo.Advocate the prerequisite of environmental protection according to present country, the heavy steel plate storehouse will be as the main storage device of 21 century powder material.Mass transport is compared in heavy steel plate storehouse and Li Pu storehouse (annotate: basis, Li Pu storehouse is adopted and cut down plate base, and foundation cost is than higher, and cylindrical shell is that thin-walled steel plate seaming forms, and discharging is mainly used in middle roll-over and storehouse in bulk by action of gravity) a lot of immature parts.
