Abstract

PURPOSE: To continuously select and remove large size solid material in dredged material without stopping dredging operation, a number of selectors are installed in parallel in the moving passage of dredged material and made switching operation.
CONSTITUTION: When dredged material is transferred into the dredge moving pipe 2A, large solid materials such as gravels and waste products are selected by the selector 1A, and only slurry is moved through the slurry moving pipe 2B. Large solid material is stored on the plate valve 7A at the exhaust outlet 5A. When the pressure difference between the dredge inlet 3A and the slurry outlet 4A exceeds the set value, the plate valve 7B at the exhaust outlet of the other selector 1B closes and the inlet plate valve 5B and flow outlet plate valve open. Next, the flow outlet plate valve 6A of the selector 1A and the flow inlet plate valve 3A close and the exhaust outlet plate valve 7A opens to discharge large solid in the selector 1A.
