分流装置
Document Type and Number:
Japanese Patent JP7033736
Kind Code:
B2
Abstract:
To provide a diversion device which, when transporting snow particles in a straight pipe line by transport airflow and communicating an outlet side of the straight pipe line with a plurality of diversion pipes thereby performing diversion, can suppress variation in snow particle concentration for each diversion with a simple structure.SOLUTION: A diversion device 100 has: a straight pipe line 110 which transports snow particles S by transport airflow F; a throttle part 120 which is so provided at a prescribed position in the straight pipe line 110 as to narrow a flow passage area; a partition 150 which partitions an outflow port 130 of the straight pipe line 110 into a plurality of areas 140A to 140C; and rectifying grids 160A, 160B which are provided on an upstream side in a transport direction of the throttle part 120. The partition 150 radially extends toward a peripheral edge 170 from a central part C of the outflow port 130. The rectifying grid 160 has its whole cross section crossing an extension direction of the straight pipe line 110 formed in a mesh-like shape.SELECTED DRAWING: Figure 2
