発明の名称 (英語) BUBBLE FORMATION DEVICE AND BUBBLE FORMATION METHOD NEW
発明の概要(英語) A bubble formation device (500) comprises a rotor (100), a container (200) in which the rotor (100) is accommodated along with a liquid (LQ) and a gas (GS), and a rotation device (300) that causes the rotor (100) to rotate in a state in which the rotor (100) is pressed against an inner bottom face (221) that is an inner face of the container (200). Bubbles are formed by way of periodically repeating pressurizing and depressurizing a mixture of the gas (GS) and the liquid (LQ) in the gap between the portion of the rotor (100) pressed against the inner bottom face (221) and the inner bottom face (221) due to the rotation of the rotor (100) by the rotation device (300).
従来技術、競合技術の概要(英語) BACKGROUND ART
As disclosed in Patent Document 1, a bubble forming device is known that forms bubbles using an airtight tank and a rotor that rotates on a bottom surface of the tank. In addition to the rotor, a porous material connected to a gas source that releases gas, and a tube interposed between the porous material and the rotor are disposed in the tank.
In this bubble forming device, the gas is released from the porous material in a tank filled with a liquid. The released gas is guided around the rotor by the tube. The gas guided around the rotor is agitated by the rotor to form bubbles.
