DEPOSIT-RAKING APPARATUS AND PRESSURE FLUID SUPPLY/DISCHARGE CONTROL METHOD IN THE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for raking sludge or the like capable of easily coping even with a deep layer depositing pond and an underground rain water depositing pond or the like without the need of disposing a mechanical movable part and a mechanical driving device inside a settling tank, and to provide the apparatus for raking sludge or the like which is easily maintained and managed without the need of disposing special equipment. SOLUTION: In this deposit raking apparatus of settling separation equipment in water treating facilities, a settling sludge moving means composed of an inclination member for which one side of a rectangular planar body is turned to a sludge gathering pit part side, the end part of the one side is freely swingably fixed by a hinge member and the other opposing side is formed as a vertical free end and a bag body in a sealed structure disposed on the lower surface side of the inclination member is successively provided for two or more stages on the bottom part other than the sludge gathering pit part of the settling separation equipment. A pressure fluid supply means for supplying a pressure fluid to the bag body to incline the rectangular planar body of the inclination member and moving the settling sludge or the like to the sludge gathering pit part side is included.
