PROBLEM TO BE SOLVED: To provide a stirring vessel of air-permeable type capable of efficiently melting a gas to be fed, into an internal liquid of a mixing tank. SOLUTION: This stirring vessel includes a stirrer 3 inside the mixing tank, and the stirrer 3 has a stirring shaft 4 and a stirring blade 5 fitted to the stirring shaft 4. The stirring blade 5 has a blade-side air permeable hole 21 for permeating the gas inside the stirring blade 5. In addition, the blade-side air permeable hole 21 has air feed orifices 20a and 20b for feeding the gas to the edge part of the stirring blade 5. Besides, gas feeder means 14 and 15 for feeding the gas into the blade-side air permeable hole 21 are connected with the blade-side air permeable hole 21. COPYRIGHT: (C)2011,JPO&INPIT |
