Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slurry discharge port and a method for uniformly loading slurry into the hold of a slurry ship.

Conventionally, in order to efficiently handle cargo such as iron sand and ore (hereinafter simply referred to as cargo), the cargo was made into a slurry and loaded into the hold of a ship using a pump, and then dehydrated in the hold to form powdered cargo. When loading the cargo on the slurry ship, it is necessary to prevent dangerous operations due to movement of the cargo due to the movement of the ship, and to In order to ensure that the calculation of the amount of cargo loaded into the vessel can be carried out without the need for complicated calculations, the cargo level in the hold must be made as uniform as possible.

For this reason, as a means for equalizing the cargo level, a method has been proposed in which the tip of the loading nozzle is bent into a hook shape, and the loading nozzle is rotated horizontally by power to load the cargo into the ship's hold. However, since the bending angle of the hook-shaped nozzle is constant, the cargo is deposited only around the far side of the nozzle during loading, and as a result, the cargo to be loaded is in the shape of a mortar, which is far from uniform. Met.

This invention solves the problems of the conventional cargo loading means as described above, and provides a slurry discharge port for a slurry ship that can make the loaded cargo level uniform.
A slurry cargo discharge port is located above the lead part, and a jet port is provided below the slurry cargo discharge port for spouting a part of the supplied slurry to the side, and the jetting pressure of the slurry cargo from the jet port is varied. This is a feature of the slurry discharge port in a slurry ship, which allows cargo to be loaded uniformly into the ship's hold.

Next, the slurry discharge port of the present invention will be explained by way of an example with reference to the drawings.

In the accompanying drawings, an apparatus for carrying out the present invention is shown in a sectional view of a main part.

As shown in the figure, a slurry cargo discharge port 2 connected to a slurry cargo supply pipe 2 is provided at the upper part of the lead line 1, and a branch pipe 5 is provided to branch from the slurry cargo supply pipe 2. The pump has a slurry cargo spouting port 3 that opens laterally below the slurry cargo discharge port 2', and a slurry cargo spouting pipe 6 that extends vertically through the slurry cargo supply pipe 2. It has a structure in which it is connected via 4.

Therefore, when slurry cargo is transferred from outside the ship to the slurry cargo supply pipe 2 by a separately provided pump (not shown), a portion of the slurry cargo is transferred to the slurry cargo discharge port 2 through the slurry cargo supply pipe. Although it is discharged within 1,
The other part is similarly discharged from the spout 3 into the hold by the pump 4 through the branch pipe 5 and the slurry cargo jet pipe 6.

In this case, since the spout 3 faces to the side, the slurry cargo discharged from the spout 3 is spouted sideways, but the slurry cargo discharged from the spout 2' is also spouted sideways. Blown to the side by slurry cargo.

Furthermore, if the jetting pressure of the slurry cargo is weakened by the pump 4, the slurry cargo will be discharged almost directly below the discharge port 2.

If the slurry jetting pressure of the slurry cargo from the jetting port 3 is changed by the pump 4 in this manner, the slurry jetting range from the jetting port 2 can be freely changed.

Further, it is preferable that the spout 3 is opened radially,
This makes it possible to make the stacking level of the slurry cargo within the fetal vesicle 1 more uniform over the entire area.

As mentioned above, in this invention, a part of the slurry cargo is extracted, and the ejection pressure of the extracted slurry cargo is changed to eject it into the ship's hold for slurry loading. The slurry cargo can be stacked accurately and evenly in the ship's hold without the need for such malfunctions, and it eliminates the hassle of measuring cargo carrying capacity from the deck. There is no need to perform calculations, and since there is no movement of cargo, ships are not exposed to danger, which brings about industrially useful effects.
