Abstract
PURPOSE: To make the structure of the aeration device simple and cheap and improve the aeration performance, by forming the pump-cut vane on the impeller of the pump so that ejected water may be flowed radially and by inclining the impeller water ejecting hole in a prescribed direction in the vortex chamber of the pump.
CONSTITUTION: When underwater driving material 2 is driven to rotate rotation shaft 2a, impeller 4, and pump-cut vane 13, negative pressure is generated for impeller 4, and sewage 1 in the tank is sucked from narrow hole 6a of strainer 6 as shown by arrow (a) and is sent to suction hole 4a and water ejection channel 4b of impeller 4 and the guide valve or vortex chamber 12 and is jetted into the tank again from ejection outlet 12b in a high speed. Meanwhile, external air is led into vortex room 12 through air supply means 11 as shown by arrow (b) by rotation of pump-cut vane 13 provided on impeller 4. This air is mixed with sewage 1 well because the aperture part of water ejection channel 4b is inclined upward in vortex chamber 12, and these mixed air and water become minute bubbles and are jetted radially throughout the device, and sewage 1 is agitated and exposed to air and is cleaned.
