(First embodiment)
1 and 2 show a powder loading facility 1A according to a first embodiment of the present invention. This powder loading equipment 1A is installed on a quay 2 and loads powder onto a transport ship 3. Although the powder is not particularly limited, examples thereof include fly ash and cement.

The transport ship 3 includes a plurality of storage rooms 30 arranged at a predetermined pitch in the ship's length direction (one storage room 30 is shown as a representative in FIG. 1). In this embodiment, each storage chamber 30 is covered with a hatch 31, and this hatch 31 is provided with a supply port 32 and an exhaust port 33. That is, the supply port 32 and the exhaust port 33 are provided above the storage chamber 30.

For example, the transport ship 3 may be a large bulk cargo ship having three or more storage rooms 30 and a hatch 31 that can be opened and closed. Alternatively, the transport ship 3 may be a powder transport ship with two storage rooms 30, a hatch 31 that cannot be opened and closed, and a dust collector permanently installed on the hull.

A frame 4 is placed on one storage room 30 of the transport ship 3 so as to straddle the hatch 31 in the ship width direction. The pedestal 4 is lifted by a crane (not shown) and moved between a temporary storage space on the quay 2 and a mounting position on the transport ship 3.

A conveyance device 5 is attached to the pedestal 4 for conveying the powder to the supply port 32 and dropping the powder through the supply port 32. In this embodiment, the conveyance device 5 is connected to the supply port 32 of the hatch 31. Further, in this embodiment, the transport device 5 is a ship side air slider 5A. The ship side air slider 5A is connected to a land side air slider 11 arranged on the quay 2 via a flexible tube 12. Needless to say, the land-side air slider 11 is a component of the powder loading facility 1A.

Each of the land-side air slider 11 and the ship-side air slider 5A has a downward slope from the receiving end to the discharging end, and fluidizes the powder by supplying air to the inside of the air slider. As a result, the powder flows by its own weight from the receiving end of the air slider to the discharging end.

Furthermore, in this embodiment, a dust collector 6 is attached to the pedestal 4. The dust collector 6 sucks air through the exhaust port 33. In this embodiment, the dust collector 6 is connected to the exhaust port 33 of the hatch 31 via a duct 61. The dust collector 6 is, for example, a bag filter. The dust collected by the dust collector 6 is conveyed by screw conveyors 62 and 63, and is thrown into the ship side air slider 5A.

When one storage room 30 in the transport ship 3 is full of powder, after the flexible tube 12 is removed, the pedestal 4 is moved from above the powder-filled storage room 30 to the next empty space by a crane (not shown). is relocated onto the storage chamber 30 of. For example, after the gantry 4 is once returned to the temporary storage space and the transport ship 3 moves forward or backward by the pitch of the storage room 30, the gantry 5 may be placed on the transport ship 3 again. In other words, the transport ship 3 may move forward or backward while the pedestal 4 is being relocated. Alternatively, after relocating the gantry 4, the transport ship 3 may move forward or backward by the pitch of the storage chamber 30. After that, the flexible tube 12 is reinserted between the land side air slider 11 and the ship side air slider 5A.

As explained above, in the powder loading equipment 1A of this embodiment, the transport device 5 is attached to the pedestal 4 placed on the transport ship 3, so if the transport device 5 is lifted together with the pedestal 4, the transport The position of the transport device 5 relative to the ship 3 can be easily changed. Therefore, powder can be easily supplied to the plurality of storage chambers 30.

When the transport ship 3 is stationary at a fixed position, the land-side air slider needs to be configured to be rotatable and extendable in order to switch the storage chamber 30 that supplies the powder. Moreover, since the pitch of the storage chambers 30 is relatively large, it is necessary to ensure a large extension/contraction distance of the land-side air slider. Therefore, the powder loading facility becomes considerably large.

On the other hand, when the transport ship 3 moves as in this embodiment, it is not necessary to configure the land-side air slider 11 to be rotatable and extendable. Therefore, the powder shipping equipment 1A can be manufactured at low cost. Thereby, the total cost of powder shipping can be reduced.
