Patent number: 4190372Abstract: Sludge deposit is stored in a sludge deposit receiving hopper, and the stored sludge deposit is fed onto a belt conveyor and transferred to a mixer. A hardener is fed to this mixer from a hardener hopper. A conveyor belt is disposed on the belt conveyor to measure the quantity of the sludge deposit transferred by the belt conveyor. According to this measured value of the transferred sludge deposit, the quantity of the sludge deposit fed from the sludge deposit receiving hopper and the quantity of the hardener fed from the hardener hopper are controlled. The sludge deposit is mixed and kneaded with the hardener, and the sludge deposit is solidified.Type: GrantFiled: December 30, 1976Date of Patent: February 26, 1980Assignee: Takenaka Komuten Co., Inc.Inventors: Atsushi Takagi, Hiroyuki Kuroiwa, Mitsuo Miura, Teruo Mizuhata, Takefumi Ito, Masao Miyaguchi, Tateo Kawamura
