Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo handling facility using a slurry ship which functions as a relay station for loading a carrier with a load from a harbor without a storage facility or a loading facility.

[0002]

2. Description of the Related Art In a conventional slurry ship, for example, as shown in FIG. 7, at a loading station 31 constructed in a port, a material to be conveyed of a stock pile 30 is carried into a mixing tank 33 by a belt conveyor 32, In the mixing tank 33, it is mixed with fresh water 34 to form a slurry, and this slurry is pumped.
5 is conveyed to the slurry loading buoy 37 via the slurry hose 36, and the slurry loading hose 38
Slurry carrier 3 moored to slurry loading buoy 37
The slurry is loaded into the hold of No. 9 through the slurry loading pipe, drained, and then transported. In addition, when unloading, sand iron in the hold is carried out by grab using a gantry crane, etc. installed at the port.

[0003]

By the way, the transported object that has been mined is once transported from the mining site 40 to a port where it can be loaded as slurry or powder, and when a certain amount is accumulated in the storage facility (stock pile 30), It is customary to dock a slurry carrier and load it with the loading facility 31.

However, in this way, it requires a great deal of money to construct one port facility and one storage facility for one mining yard, and the mining yard is large in scale and it is profitable to meet the construction cost. The situation is that there are very few places.

The present invention solves the above-mentioned problems by using a slurry ship as a relay station, and a slurry cargo handling facility using a slurry ship which enables storage of transported objects and loading on the carrier at low cost. The purpose is to provide.

[0006]

In order to solve the above-mentioned problems, a slurry cargo handling facility utilizing a slurry ship of the present invention is a slurry ship which is moored offshore from a slurry transportation device installed at a mining yard. A slurry loading pipe for sending the slurry transported via the transportation hose to the hold,
A drainage device that discharges slurry water from the slurry in the hold, a grab-mounted crane that can carry out the transported objects after dewatering inside the hold from the hold mouth, and a belt conveyor that can carry the transported objects from the grab-mounted crane. And a device for arranging the belt conveyor device along at least one port side and equipped with a traveling type tripper on the belt conveyor device. Further, a loading belt conveyor device capable of loading objects to be transported is provided.

[0007]

In the above structure, the slurry ship is moored offshore, and the transported objects successively transported from the mining field are loaded into the hold from the slurry transport hose through the slurry loading pipe and dehydrated by the drainage device. And store. Then, when a predetermined amount is stored, a carrier ship is laid sideways on the port side of the tripper installation side of this slurry ship, and the transported objects after slurry dewatering are carried out from the warehouse to the belt conveyor device using the crane grab. , The traveling type tripper of the belt conveyor device is loaded into the hold of the carrier ship from the opening of the carrier via the unloading conveyor device, and the transported object is evenly loaded on the carrier ship while the tripper is traveling.

[0008] As a result, the port can be used as a relay station for loading the transported object on the carrier without constructing the port facility and the storage facility in the port that cannot be docked, and the cost can be reduced compared with the facility construction cost. Moreover, since it can be easily moved, it can be used moored offshore at another mining site after the mining site is exhausted and can be used efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a slurry handling facility using a slurry ship according to the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, reference numeral 1 denotes a slurry boat 1 for silica sand of 60000t class, which is provided with a plurality of holds 2 in the fore and aft direction of a hull, and a slurry loading pipe 3 through a rotary nozzle 4. The slurry water is drained from the slurry loaded in the hold 2 by a plurality of cylinder type filters 6 arranged on the double bottom upper bottom plate 5 and a flat plate type filter 8 provided at the lower end of the partition wall 7. The supernatant slurry water can be discharged to the outside from the valved drain port 9 and the overflow drain port 10 provided on the upper part of the partition wall 7, and the silica sand S of the transported object that has been slurry transported can be stored in the hold 2.

On the deck of this slurry ship 1, a plurality of grab buckets that can carry out the silica sand S in the hold 2 at a predetermined position between the hatch coaming (warehouse) 11 and carry out from the hatch coaming 11 are provided. A deck crane 12 is installed. Further, on the peripheral deck of the hatch coaming 11 of the hold 2, as shown in FIGS. 3 to 5, a starboard belt conveyor device 13 arranged in the bow-stern direction on the starboard side,
The port side belt conveyor device 14 arranged on the port side in the aft direction and the stern side belt conveyor device 15 to which the starboard belt conveyor device 13 and the port side belt conveyor device 14 are connected are arranged on the stern side. The starboard belt conveyor device 13 is provided with a hopper 16 for receiving the silica sand S dropped from the deck crane 12 corresponding to each hatch coaming 11, and configured to send the silica sand S from the bow side to the stern side. Has been done. In addition, the port side belt conveyor device 14 conveys the silica sand S from the stern side to the bow side, and the port side belt conveyor device 14
The traveling tripper 17 is equipped with a traveling type tripper 17, and a frame of the traveling type tripper 17 is equipped with a telescopic type loading belt conveyor device 18 that can freely move in and out on the port side.
Are rotatably arranged within a predetermined range so that they can be uniformly loaded in the hold of the silica sand carrier 27.

A method of using this slurry ship will be described. As shown in FIG. 6, the slurry ship 1 is moored in the bay near the silica sand mining site 21, the slurry carrier 22 provided in the mining site 21 slurries the mined silica sand S, and the slurry is pumped by the pump device 23. It is sent from the loading hose 24 to the slurry loading buoy 25, and is conveyed from the connection hose 26 of the slurry loading buoy 25 to the hold 2 via the slurry loading pipe 3 of the slurry vessel 1. In the hold 2, the slurry water is drained through the cylinder type filter 6 and the flat plate type filter 8, and is drained from the valved drain port 9 and the overflow drain port 10.

When a predetermined amount of silica sand S is stored in the hold 2, a silica sand carrier 2 of 30,000t class
7 is horizontally mounted on the port side, the deck crane 12 is driven, the silica sand S in the hold 2 is gripped by the bucket, and the silica sand S is carried out to the hopper 16 on the starboard side. The silica sand S discharged from the hold 2 in this manner is conveyed from the starboard belt conveyor device 13 to the port side belt conveyor device 14 via the stern belt conveyor device 15 and from the traveling tripper 17 to the loading belt conveyor device 18. It is then dropped and loaded into the hold of the silica sand carrier 27.

Incidentally, the slurry ship 1 used in this way can be used even after the mining site 21 has been dug up and closed.
It can be moved to another mining site for use. Of course, it can be used in the same manner as a general slurry carrier, and since it is equipped with unloading equipment, it can also be unloading at a port without unloading equipment.

[0015]

As described above, according to the present invention, since the slurry ship is provided with the equipment capable of loading the side-by-side carrier, it is not necessary to construct the port equipment and the storage equipment in the port which cannot be docked. Since it can be used as a relay station for loading objects to be transported on a carrier, the cost is lower than the equipment construction cost, and it can be easily moved, after the mining site is exhausted, the next mining site will be used again. It can be moored offshore and used efficiently.
