Definitions

  • a cargo vessel for handling materials received in the form of a slurry is provided with a dewatering device comprising a series of upstanding conduits having filtering means along the entire height of the wall of the tank to discharge the water from the slurry into the ballast tanks of the vessel, from which it may be discharged by the conventional ballast pumps, ifdesired.
  • This invention relates to a slurry tanker, more particularly to a tanker suitable for carrying an ore slurry or coal slurry.
  • iron ore is carried by means of the land carriage from diggings to a harbor and loaded in a cargo ship.
  • the draining means comprising pipes constructed by permeable members or frames covered by filter members are provided along the inner wall of the tank. Water in the slurry is separated and collected by the draining means in loading or in navigating and discharged outboard or in the ballast tank of the ship.
  • FIG. 1 is a side view of the slurry tanker in accordance with this invention.
  • FIG. 2 is a plane view of the slurry tanker
  • FIG. 3 is a cross-sectional view of the slurry tanker
  • FIG. 4 is a perspective view showing the draining pipe
  • FIG. 5 is a perspective view showing another type of a draining device.
  • FIG. 6 is a diagrammatic vertical section view showing a discharging system.
  • draining pipes 1 comprise frames having a desired shape in section such as round or square, the frames being covered by a filter member 3 as shown in FIG. 4.
  • the filter member is constructed by a suitable permeable member such as a perforated plate, for example made of an unglazed pottery or made of alloy of stainless steel by powder metallurgy, or a wire netting made of stainless steel or bronze according to grading of the slurry.
  • the draining pipes l are secured by band steels 6 to the inner wall of a tank 2 taking the vertical direction.
  • FIG. 5 shows a draining device comprising a frame work 5 provided with the filter member 3, and the frame work being secured to the inner wall of the tank.
  • the cargo which is solidified may be landed by a grab. If there is no grab at the landing place, the cargo is changed into slurry again by adding water and landed by a slurry pump.
  • the draining pipe may be easily substituted by the other draining pipe according to a slurry to be carried.
  • a slurry tanker having a cargo tank and a ballast tank comprising draining means consisting of a plurality of upstanding conduits coextensive in height with said tank and disposed at spaced intervals along an inner wall of the cargo tank, said conduits having at least one filter member extending along the length thereof to drain the liquid from the slurry in the tank, and discharging means for liquid connecting said conduits and said ballast tank and having means for regulating the quantity of discharge, said ballast tank having pump means for discharging liquid therefrom.
