<p>PROBLEM TO BE SOLVED: To provide a novel night soil liquid aerating and agitating device capable of enhancing the treating capacity of the agitating and aerating of the night soil liquid. SOLUTION: A revolving shaft 7 connected to a driving means arranged on the outside of a night soil liquid tank 1 is introduced in a posture inclined diagonally to have an angle with a perpendicular direction and a horizontal direction, respectively, into the light soil liquid tank. An air diffusion pipe 9 for exposing the air suction pipe 10 at its top end to the outside of the light soil liquid tank 1 is likewise introduced into the light soil liquid tank. Rotary vanes 8 for air suction in common use for agitating are mounted at the front end of the revolving shaft 7 so as to face the discharge port 12 at the bottom end of the air diffusion pipe 9 opened in the night soil liquid 11. The device is provided with a cylindrical fan case 13 which is opened at both ends to the discharge port 12 of the air diffusion pipe 9 and the circumference of the rotary vanes 8 for air suction in common use for agitating, sucks the night soil liquid 11 from the one end and discharges and circulates the night soil liquid from the other end.</p> |
