APPARATUS FOR REMOVING SEDIMENTS FROM BALLAST TANKS OF VESSELS

摘要

The object of this invention is to provide an apparatus for removing sediments from the ballast tanks of vessels. This apparatus has a main supply pipe (4) connected to a seawater inlet pipe (2) through a water pump (3). A plurality of sub-supply pipes (5, 5') are branched from the main supply pipe (4), with a valve (6, 6') being installed on each of the sub-supply pipes (5, 5'). A seawater ejection pipe (7, 7') extends from each of the sub-supply pipes into a ballast tank (1, 1'). A plurality of ejection nozzles (11, 11') are formed on the ejection pipe at positions between the reinforcing ribs (9) arrayed on the bottom (10) of the ballast tank, thus ejecting cleaning seawater under pressure onto the bottom (10) of the ballast tank. In this apparatus, each of the ejection nozzles (11, 11') preferably has a diameter of 0.1 mm SIMILAR 50 mm. The apparatus of this invention ejects cleaning seawater under pressure onto the bottom (10) of a ballast tank (1, 1'), thus allowing a variety of sediments, such as mud, microorganims and/or solid impurities, to float in ballast seawater within the tank (1, 1') and effectively removing the sediments from the tanks when discharging the ballast seawater.
