PURPOSE:To efficiently collect enriched oxygen gathered at a part for forming a magnetic field with a simplified structure, by providing said part for forming a magnetic field at a rotary disc and a squeezer for covering a part of the rotary disc while being connected to a decompressed hermetically-sealed chamber above the disc. CONSTITUTION:A dent part is formed on the plate surface 2 of a rotary disc 1, an N pole 5 is provided inside said dent part, and a gas-magnetizing part 3 equipped with an S pole 15 is formed at the periphery. When oxygen-contg. gas, e.g. air, comes in contact with the disc, oxygen is magnetized and attracted into the gap 3A of said gas-magnetizing part 3. Thus, oxygen-rich gas is accumulated in the gap 3A. A squeezer is provided above the plate surface 2 of the rotary disc 1, its end parts 6, 16 are equipped with seals 7 to form a hermetically sealed chamber 8, and a suction fan 9 communicated to the hermetically sealed chamber 8 is provided. Hence, by the rotation of the disc 1, the oxygen- rich gas accumulated in the gap 3A of the magnetizing part 3 is let flow into the squeezer and recovered by sucking with a suction fan 9. |
