Title:
MOORING TYPE SUCTION TYPE PUMPING-UP DEVICE
Document Type and Number:
Japanese Patent JP3110165
Kind Code:
B2
Abstract:
PURPOSE: To reduce the necessary power and permit the circulation of the bottom layer water and economic aeration by pumping up the bottom layer water inside a pumping-up cover from a pumping-up cylinder, accompanied with the drive of a vacuum pump, dropping the water intermittently from a punping-up tank and specifying the area ratio of each part.
CONSTITUTION: An elliptical cylindrical pumping-up cylinder 1 has a floating body 5 in the upper part, and the lower part is moored with a sinker 7 on the sea bottom by a plurality of chains 6. At the upper edge of the pumping-up cylinder 1, a basin shaped pumping-up tank 2 is formed in coaxial form. Further, in the upper part of the pumping-up tank 2, a water pumping-up cover 3 having a turned-down shaped basin shape is supported coaxially. Further, the air inside the pumping-up cover 3 is vacuum sucked by a vacuum pump 9. The annular sectional area between the pumping-up cylinder 1 and the pumping-up cover 3 is set sufficiently large in comparison with an annular horizontal sectional area between the pumping-up core 3 and the pumping-up tank 2. Accordingly, the pumping-up core 3 and the pumping-up tank 2. Accordingly, the bottom layer water is pumped up inside the pumpig-up cover 3 through the pumping-up cylinder 1, accompanied with the drive of the vacuum pump 9, and dropped intermittently from the pumping-up tank 2.
