寄せ装置。[Scope of Claim for Utility Model Registration] Flights that scrape up sludge accumulated in a settling tank of a sewage treatment facility into a sludge hopper, and also scrape up scum floating on the water surface into a scum skimmer, and where the flights are positioned at appropriate intervals on the outer periphery. An endless chain is attached to the water surface and is supported by multiple sprockets and driven in rotation, and the scum scraping part on the return side of the chain is supported below the water surface, and a part of the flight on the return side is raised above the water surface. a first support means for protruding; and a second support disposed below the scum gap on the downstream side of the first support means in the chain circumferential direction and for supporting the submerged part on the return side of the chain. and a guide member disposed between the first and second support means to face the flights of the chain in a suspended state, and for preventing the flights from contacting the scum gap. The chain flight type sludge scraping device is characterized in that the guide member is supported under pressure against the flights, and the length of the contact surface with the flights is at least longer than the maximum installation interval dimension of the flights. Chain flight type sludge scraping device.
