DISPOSAL SYSTEM FOR DREDGING EARTH AND SAND

摘要

PROBLEM TO BE SOLVED: To provide a small type and highly efficient classifying disposal system for a dredging earth and sand, in which a sand portion extracted from the earth and sand dredged from coastal areas and rivers is taken as a result of its classfication. SOLUTION: An aqua screen 70 as a classifying system is placed on a tank 30 with a feed sump 30. A liquid cyclone 50a to 50d and a spigot tank 60 are placed on the aqua screen 70. Compressed muddy water including a dredging earth and sand is carried from a natural water introduction tube 10 to a feed sump 30. The natural water stored at the bottom of the feed water sump 30 is supplied to a succion type liquid cyclone 50a to 50d. A large particle sized particulate body is separated from a slurry including the large particle sized large particulate body, which is discharged from below part of each liquid cyclone 50a to 50d, by the aqua screen 70, and a desalination for the particulate body is carried out.
