The specific embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
A kind of stacked arrangement of petroleum coke, it adopts layer by layer compacting by the trapezoidal driving surface of storing up on lower the reaching, and every shop one deck petroleum coke carries out a compacting, repeatedly forms a petroleum coke after the compacting and piles up.
As shown in Figure 1, petroleum coke is discharged in the groove of unloading coal, then stacks the place delivering to petroleum coke through travelling belt, stack in the petroleum coke stockyard according to the petroleum coke stacked arrangement and just can finally by crossing stocker.
Described compacting angle of rest (repose) scope is 45 °～75 °.
The height of each time compacting is 2.0～5.0 meters, after petroleum coke is stored up thickness and is reached 2.0～5.0 meters, with construction machinery and equipment with its compacting after, stacking the second layer, store up from bottom to top successively, heap is till require height always, and each compacting reduction thickness is 300～500mm.
Its bottom-to-top-height of storing up is 4.0～10.0 meters, and the top constructional surface is decided according to actual conditions.
Such as Fig. 2, calculate its volume take the burnt stacking volume of common petroleum as circular cone, the maximum angle of rest (repose) θ of the burnt stacking method circular cone of common petroleum
1Be no more than 45 °, get θ
1Be 45 °, generally about 35 meters, its volume computing formula is floor space diameter D: V=π R
2H/3,
Wherein R is the bottom surface radius, is 35/2 meter,
35/2 meter of h=tg45 ° of *,
V1=5612m then
3
Such as Fig. 3, with the round platform volume calculated that the present invention piles up, can allow angle of rest (repose) θ
