Abstract

PURPOSE: To prevent the freezing in a suction port part by interposing a heat exchangeable bypass circuit between a suction part and discharge air in a device wherein a blower body is installed in a water tank and suction and discharge pipes and exposed in air.
CONSTITUTION: Air sucked through double cylindrical bodies 10 is accelerated by a blower body 1, and is ejected into water in a heated state through air diffusion pipes 9. During operation in a winter time, a stop valve 14 is closed, and stop valves 12, 16 are opened to form a bypass. Thereon, the air heated in said blower body 1 warms up an air suction passage 10b in the outside cavity part 10a of the bodies 10 and ejects into an aerating tank 7 through the pipes 9. Hence, the air suction port is prevented from freezing.
