Abstract
PURPOSE: To remove sewage from sewage mixed sand precipitate collected from a sewage treating plant by generating a whirled rising stream along with supplied water in an inverted conical shaped funnel.
CONSTITUTION: When a motor 7 is started and water is supplied into a container 2 from the upper part thereof and sewage mixed sand precipitate is supplied into a funnel 3 from a hopper 5, the sewage mixed sand precipitate is introduced into water being whirled and raised along the inner surface of the funnel 3 by a rotary blade 9 and revolved and whirled together with supplied water along the upper inner surface of the funnel 3 and plant, feather, seed and other sewage lighter than sand are floated to a gap (t) and overflowed out along with water from a flooding flange 3' formed to the inner surface upper end circumference of the funnel 3 through the gap (t). Sand particles are precipitated by own weight against the whirled rising stream and a precipitated sand bed 13 is formed to the lower part thereof. This precipitated sand bed is discharged dowardly from the opening and closing valve 11 of a lower end discharge port 3".
