Abstract:
To provide a sludge scraping device capable of suppressing that traveling of endless chain get disordered even when a regulation member is brought into contact with a rail member in a sludge scraper provided in a sedimentation basin in which sludge contained in water while the sludge-containing water flows is deposited on a basin bottom part.SOLUTION: A sludge scraping device includes an endless chain 11 which allows a plurality of scraping members 12 to be attached thereto with an interval, travels and, thereby, circulates the scraping members 12 on the basin bottom part 1d side and the water surface WL side and a first rail member 24 which is elongated in a water current direction, allows the scraping members 12 to be placed thereon and allows the scraping member 12 to slide when the endless chain 11 travels, the scraping member 12, when the endless chain 11 deflects, is brought into contact with the first rail member 24, therefore, has a regulation member 123 which regulates deflection of the endless chain 11 and the regulation member 123 is configured such that a contacting surface 1233s which might be brought into contact with the first rail member 24 from the upper side by the travelling of the endless chain 11 is inclined toward the lower side.SELECTED DRAWING: Figure 3
