Abstract

PURPOSE: To collect high quality sand by sending the sand and sea water sucked up by the sand pump to a selection chamber and removing the sludge type clay contained in the sand in the chamber by use of the sea water.
CONSTITUTION: This sand collector consists of a sand pump 1, separator 6, selection chamber 10, and inclined lifting conveyor 9, etc. The bottom of the separator 6 is connected to that of the selection chamber 10 and both sand and sea water flow in the selection chamber 10 from here. The selection chamber 10 separates the sand into that which has large particles and fast precipitation speed and the hedrolike clay that has small particles and slow precipitation speed. The turning plate 15 is inclined with an upward gradient to the flow direction. The steam plate 16 generates the upward stream by the effect foams and improves the separation effect in the chamber 10.
