<p>PROBLEM TO BE SOLVED: To enable aeration agitation and rapid putrefaction ripening while circulating a night soil liquid 11 by inserting a revolving shaft 7 to be rotated into a pipe-like shaft cover 6, mounting rotary vanes for agitation and air suction at the protruding end thereof and disposing an outdoor charging pipe near these rotary vanes 8. SOLUTION: When the revolving shaft 7 is rotated by an engine, etc., of a tractor, the rotary vanes 8 for agitation and air suction are rotated as well and the night soil liquid is sucked from the opening at one end into en enclosure case 13, by which the night soil liquid is agitated and simultaneously the night soil liquid agitated by the air sucked from the outdoor air charging pipe 9 by rotation of the rotary vanes 8 for agitation and air suction is aerated. The night soil liquid, thereafter, flows out of the opening at the other end of the enclosure casing 13. At this time, the night soil liquid is rapidly putrefied and ripened by the agitation and aeration and is made usable as an org. fertilizer. At the time the night soil passes the inside of the enclosure case 13, the straw dust, etc., intruding into the light soil liquid is cut off and shortened by the edge part of a knife 22 and the blades 25 disposed at the edges of the rotary vanes 8 for agitation and air suction.</p> |
