出される。 Next, the action will be explained. First, the case where it is used for continuous reading will be explained. Sludge input hopper 2
The sludge from No. 1 and the dewatering agent from the dehydrating agent charging hopper 23 are continuously charged into the rotating drum 1 by a sludge charging screw 22 rotated by motors 25 and 26. Rotating drum 1 is motor 11
It rotates at 5 to 10 rpm. The sludge in the rotating drum 1 is stirred and rotated by the stirring blades 30 and 31, and is gradually sent forward by the screw blade 32 and falls onto the gutter 13 one after another. The discharge screw 14 in the gutter 13 is rotated in the normal direction by the forward/reverse motor 15 and discharged to the outside of the rotating drum 1. Hot air and water vapor generated by the reaction between the sludge and the dehydration treatment agent in the rotating drum 1 are discharged into the duct 34 through the through hole 33 of the outlet fixing plate 9.
