Abstract
A sludge handling system includes a bin from which treated sewage sludge is discharged. A rotabable discharge device includes an arm for scraping the inside of the bin and a frusto-conical chute from which sludge is discharged through a gate to a waiting truck. A stationary scoop is provided mounted on the gate to scrape the interior wall of the chute of adhering sludge.
Claims16
A sludge handling system comprising:
- at least one bin from which bin treated sewage sludge is discharged;
- the at least one bin having an inlet at an upper end for receiving sludge therein, a bottom central discharge opening for discharge of sludge therethrough, and side wall(s), at least portions of the side wall(s) being generally conically sloped toward the bottom central discharge opening,
- a rotatable discharge means including a rotably driven table;
- the rotatable discharge means including at least one arm having an upper portion and a lower portion, the at least one arm being mounted for traversing proximate the sloped portions of the side wall(s) of the at least one bin, and for moving sludge from the sloped portions of the side wall(s) so that the sludge does not adhere to the sloped portions of the side wall(s) and is directed out the bottom central discharge opening;
- the rotatable discharge means including a rotationally symmetric chute, the rotationally symmetric chute having an upper end for receiving sludge from the bottom central discharge opening of the at least one bin, a lower end for discharging sludge, and a wall extending between the upper end of the chute and the lower end of the chute, the lower portion of the at least one arm being mounted on the rotably driven table;
- a discharge gate having an opening for receiving sludge from the lower end of the chute, the discharge gate including at least one scoop extending into the chute proximate the wall for dislodging sludge from the wall.
