ことが好ましい。In order to prevent sedimentation and accumulation of solid components in the weir box portion for the discharge pipe, as shown in FIG. 1, the side surface of the weir box for the slurry discharge pipe is formed as a slant at the bottom to reduce the cross-sectional area of the weir box. It is preferable that the shape is such that it moves to the slurry discharge pipe.
なお記号７はガス抜きである。It should be noted that symbol 7 is a gas vent.
