Document Type and Number:
WIPO Patent Application WO/2014/112255
Kind Code:
A1
Abstract:
[Problem] To provide a pressurized liquid lifting device and a liquid lifting method that make it possible to use a pressurized air pump to lift a liquid to a height that is equal to or higher than the height to which the pump is capable of lifting the liquid. [Solution] A liquid lifting device (1) is provided with: a liquid lifting tank (2) in which a liquid is stored; an air pump (10) that pressurizes the inside of the liquid lifting tank; a liquid lifting pipe (3) in which one end is connected to the liquid lifting tank, the liquid-conveying port of the other end stands upright, and the height (h2) from the liquid surface in the liquid lifting tank to the liquid-conveying port of the other end is higher than the height (h0) to which the pressurized pump is capable of lifting the liquid; a supply pipe (5) comprising one end section that is connected to a branching section (4) provided to an intermediate position in the liquid lifting pipe and an upright section on the other end section thereof; an air valve (6) that is provided to the other end section of the supply pipe and that can be opened and closed with respect to the outside air; and a liquid storage section (7) that is formed in the part of the liquid lifting pipe that is between the liquid-conveying port of the other end and the branching section and that is positioned below the branching section. The branching section (4) is provided to a position that is higher than the height of the liquid surface in the liquid lifting tank and lower than the height (h0) to which the pressurized pump is capable of lifting the liquid.
