Abstract

PURPOSE: To make circulating flow uniform from the upper part of a veseel down to the lower part by extending a revolving shaft, providing vanes agitating water by forcing it out downward and further providing a cushion cover thereby making it possible to deal with the fluctuations in the water level.
CONSTITUTION: Vanes 11 for scooping up of water are mounted to a revolving shaft 10 of a motor 9 of an aerator 3 provided afloat to a float 4 in an aeration vessel 2, and a suction pipe 5 is connected to the float 4. A revolving shaft 12 is joined to the bottom end of the shaft 10, and a projecting screw 13 is provided to the lower part thereof. The screw 13 holds the top end of a slit 15 provided on the side face of an extension shaft 14 making the shaft 12 slidable. Vanes 16 agitating water in the bottom direction of the vessel 2 are joined to the lower part of the shaft 14. Further, a cushion cover 18 of rubber or the like is connected to the bottom end of the shaft 14 by means of bearings 17a, 17b to prevent damaging of the shaft 14 despite the contact with the bottom part of the vessel 2 on lowering of the water level of the vessel 2.
