Patent attributes
A major object of the invention is to provide such a method for extracting slurry that is not inhibited in extraction of slurry by a released and accumulated matter or a solid matter sedimented and accumulated at the bottom of the vessel. The invention relates to a method for extracting slurry by extracting slurry from an agitation vessel having a bottom face and a side wall and housing the slurry, characterized in that the slurry is extracted from an open end of a slurry extraction tube provided at the side wall of the agitation vessel. More preferably, a normal line direction of a surface of the open end is in a direction of an angle with respect to a downstream direction of a flow of the slurry caused by agitation of 0° or more and less than 90°.
