Tanker for mud.

The invention relates to a tanker for sludge, in particular a tanker for the transport of ore sludge or coal sludge or a corresponding slurry.

Iron ore is usually transported overland from the pits to a port and loaded onto a barge. However, where there is no port near the pits, it is advantageous to pass the iron ore through as sludge to transport a pipe line and load it directly onto the ship. To simplify later processing of iron ore it is desirable, the mud

to drain at sea.

The object of this invention is to provide a sludge tanker with a dewatering device for the sludge.

According to this invention, the dewatering device, Pipes on, ■ made from permeable parts or from frames, which are covered with filter elements are constructed, are attached along the inner walls of the tank room. The water in the mud is separated and collected by the drainage device during loading or underway and outboard or into the ballast tank of the ship.

An example embodiment of the invention is explained below with reference to the drawing:

According to Figures 1 to 4, the drainage pipes consist of frames as desired, such as round or rectangular Cross-section, which are covered by a filter element 3, as shown in FIG. The filter element is of a suitable, permeable material, such as a permeable plate made, for example, of unglazed clay or an alloy of stainless, sintered steel, or a wire mesh of stainless steel or bronze as the case may be Type of mud may exist. The drainage pipes 1 are fastened to the inner wall of the tank 2 in by steel straps 6 attached in the vertical direction. Figure 5 shows a drainage device with a frame structure 5, the filter elements 3 carries and is attached to the inner wall of the tank.

The water that is in the sludge in the tank flows into the drainage pipe 1, and that in the pipe Collected water is passed through the Kohr 7 into the ballast tank 8 discharged, as Figure 6 shows «. If the remote-controlled valve 9 is closed at an appropriate moment, the water is retained in the sludge in the desired amount. The water that collects in the ballast tank 8, is pumped out of the boat by a ballast pump provided on the ship.

At the landing site, the solidified cargo can be brought ashore with a ™ grapple. If there is no grapple at the landing site, the load will only be available by adding water back into 5chlar.Tr: transformed and brought to Lend by a mud pump. The drainage pipes can easily be replaced by other drainage pipes depending on the type of mud being transported will.
