Title:
UNDERWATER BUBBLE EXCAVATING DEVICE
Document Type and Number:
Japanese Patent JP3460053
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an underwater bubble excavating device having high force feed power at a low-speed rotation, a weak noise vibration, a small energy loss, a high pressure, and a strong air lift effect and suction force with a simple structure and via a simple action in the water, lifting excavated objects and collected objects from the underwater, and aerating deep layer water.
SOLUTION: A pump 1 force-feeding gas and liquid into the water is used. The gas and liquid are pressurized and force-fed to an underwater gas-liquid separation chamber 3, the liquid is discharged to the outside from the lower section of the gas-liquid separation chamber 3, and the gas passes through a siphon 4 from above and is automatically sent out from a bubble extrusion port 6 as bubbles. Bubbles enter an air lift pipe 7 and rise in it to cause an air lift effect and also to cause suction force at the suction port 9 of a suction pipe 8 connected to the lower end, and excavated objects, collected objects and deep layer water at the depth of the underwater 14 are sucked and lifted to the surface. The gas-liquid separation chamber 3 and the siphon 4 are provided on a gas-liquid force feed pipe 2 and the air lift pipe 7.
