SLURRY TREATMENT EQUIPMENT FOR SLURRY PRESSURIZING AND DRIVING

摘要

PROBLEM TO BE SOLVED: To prevent vibration and noise generated from slurry treatment equipment for slurry pressurizing and driving. ;SOLUTION: Reflux slurry containing sediment excavated by a slurry pressurizing type small-diameter pipe driving equipment is filled from an inlet 9, sediment is accumulated in a lower region of a mesh member 11, and filtered slurry is run off to an upper portion of the mesh member 11. A current of filled slurry is changed to an arch shape along the mesh member 11, a convection occurs downward in a lower region of the mesh member and washes the sediment ready to be stuck to the mesh member 11 by its own current velocity and is able to avoid clogging without occurrence of vibration. The mesh member 11 is sunk in water and causes a convection in slurry, a force to stick sediment on the mesh member 11 is weakened thereby efficiently realizing the prevention of clogging. Slurry run-off in the upper region of the mesh member 11 overflows from a weir 13 flows down to a pipe 15 and flows into a slurry treatment tank 5, and slurry in the slurry treatment tank 5 is agitated by its drop energy.;COPYRIGHT: (C)2000,JPO
