Description

[Detailed Description of the Invention] The present invention relates to a slurry loading device in a slurry carrier.

Conventionally, in slurry carriers, the tip of the slurry piping is inserted directly into the hatch to supply slurry from the slurry piping into the hold, and the water is dewatered from a drain port provided on the side wall of the hold, but this conventional configuration However, there is a problem in that coal, etc. supplied as slurry tends to pile up high under the tip of the slurry piping, making it impossible to load the coal, etc. evenly into the hold.

Therefore, the present invention provides a slurry loading device that solves these problems, and its feature is that through-holes are formed in the hatch coaming at appropriate intervals to communicate with the slurry main piping on the upper deck. At the same time, a slurry injection tube is provided whose tip extends to the vicinity of each of the through holes, a slurry injection cylinder is rotatably connected to the tip of each of the slurry injection tubes and whose tip is inserted into the through hole, and the injection A rotation device is provided to appropriately rotate the cylinder in the horizontal direction, and the injection cylinder has a first opening/closing lid that is attached to the opening surface of the tip so that it can be opened and closed, and an opening that can be opened and closed on the bottom opening formed on the bottom surface near the tip. The slurry injection direction adjustment device is provided with a second opening/closing lid that can be attached to the slurry injection direction. According to this configuration, by appropriately rotating the injection cylinder and activating the slurry injection direction adjustment device, Slurry can be evenly distributed in the hold, and coal, etc. can be loaded evenly into the hold, instead of being piled up in one place as in the past.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 4. 1 is a hatch coaming, 2 is a slurry main pipe extending along the longitudinal direction of the hull next to the hatch coaming 1 on the upper deck 3, 4 is a U-shaped pipe arranged in pairs around the outer circumference of the hatch coaming 1, 5 A communication pipe communicates with the center of the U-shaped pipe 4, 6 a slurry branch pipe that communicates the communication pipe 5 and the main slurry pipe 2, 7 an on-off valve, and 9 a suitable interval for the hatch coaming 1. 10 is a shelf that extends horizontally from the lower edge of the through hole 9; 11 has its base end connected to the U-shaped pipe 4, and its tip extending to the vicinity of each through hole 9; An extending slurry input pipe 12 has a proximal end connected to the slurry input pipe 1 through a flexible tube 13.
A slurry injection tube 14 is connected to the tip of the slurry injection tube 12 and has its tip protruding into the hatch through the through hole 9. caster, 1
5 is a rotary first opening/closing lid attached to the tip opening 16 of the injection cylinder 12 via a hinge 17;
The distal end opening 16 is normally kept closed by a spring (not shown). Reference numeral 18 denotes a first winding drum disposed at the base end of the upper surface of the injection cylinder 12; 19, one end is wound around the drum 18, and the other end is connected to the first winding drum via a pulley 20 on the upper surface of the injection cylinder 12; A rope 21 is connected to the opening/closing lid 15, a first drive motor 21 opens and closes the first opening/closing lid 15 via the rope 19 by rotating the first winding drum 18 in forward and reverse directions, and 22 is a first drive motor connected to the lower surface of the injection barrel 12. 23 is a sliding second opening/closing lid that opens and closes the lower opening 22 by sliding along the guide frame 24; 25 is a lid whose main body is attached to the lower surface of the injection tube 12 via a bracket; A cylinder device in which the tip of the piston rod is connected to the second opening/closing lid 23. 26 and 27 are slurry input pipes 11
second and third winding drums arranged on both sides of the 2
8 and 29 have second and third ends wound around each drum 26 and 27 at one end, and connected to brackets on both sides of the slurry injection cylinder 12 at the other end via a pulley 30 provided on the hatch combing 1. rope, 31,
32, by rotating each drum 26, 27 in the forward and reverse direction, the slurry injection tube 12 is moved through the ropes 28, 29 with the flexible tube 13 as a fulcrum, and the arrows A,
These are second and third drive motors that rotate in the B direction.

In the above configuration, when the slurry is to be introduced into the hold, the on-off valve 7 may be opened. Then, the slurry flows from the main slurry pipe 2 through the slurry branch pipe 6, the communication pipe 5, the U-shaped pipe 4, the slurry input pipe 11, the flexible pipe 13, and the slurry injection pipe 12, and then from the tip opening 16 and the bottom opening 22 into the ship's hold. It is something that is put inside. Here, the first winding drum 1 is
8 in one direction to wind up the first rope 19 and pull up the first opening/closing lid 15, the tip opening 1
The slurry injected from 6 is not obstructed by the first opening/closing lid 15 and is blown far away. When the first rope 19 is unwound from this state, the first
The opening/closing lid 15 is rotated downward by the spring, and the slurry hits the first opening/closing lid 15 and is restricted from flying. Therefore, by opening and closing the first opening/closing lid 15 as appropriate, the slurry injection distance can be freely adjusted. Further, the second opening/closing lid 23 is appropriately slid by the cylinder device 25,
By this, the opening degree of the lower surface opening 22 is adjusted,
The amount of slurry sprayed downward from the lower surface opening 22 can be adjusted. Further, at the same time as the above operation, for example, the second drive motor 31 is operated to cause the second winding drum 26 to
While winding up the rope 28, the third drive motor 32 is activated to rewind the third rope 29 by the third winding drum 27 to rotate the slurry injection cylinder 12 in the direction of arrow A, and then the second rope 28 is rotated. At the same time, the third rope 29 is wound up and the slurry injection cylinder 12 is rotated in the direction of arrow B. By repeating this rotation, the slurry can be evenly spread within the hold.

As described above, according to the slurry loading position in the slurry carrier of the present invention, the slurry injection distance is adjusted by opening and closing the first opening/closing lid provided on the injection tube that rotates in the horizontal direction, and the second opening/closing lid By adjusting the amount of slurry sprayed downward from the bottom opening by opening and closing, coal, etc. can be spread evenly over a wide area within the hold without being piled up high in a specific location. This allows coal, etc. to be loaded evenly into the hold.
