Title:
分割した縦水路の揚泥装置
Document Type and Number:
Japanese Patent JP6896206
Kind Code:
B2
Abstract:
To provide a sludge lifting device which facilitates handling for collecting and removing an underwater precipitate and can suck sludge with a long distance and practical concentration.SOLUTION: A sludge lifting device has a sand absorption port opened and arrayed along a pipe wall of a vertical direction water channel part auxiliary water absorption cylinder which maintains a tip water absorption port of a suction pipe on a precipitate, and lifts sand and sludge in a state of being embedded in the precipitate, in which a partition in the water channel direction is provided on the water channel in the auxiliary water absorption cylinder, the water channel is divided into a sand absorption port side water flow channel and a non-sand absorption port side water flow channel having the sand absorption port, and sand absorption and water absorption are separately performed and the sludge is lifted by confluence and mixing of the sand and the water on the lower end of the partition, to prevent in-pipe accumulation when the auxiliary water absorption cylinder stops, to smoothly start water passage, and to absorb sand with high concentration and absorb sand with a long distance using scouring and transaction from the surface of the precipitate.SELECTED DRAWING: Figure 1
