<P>PROBLEM TO BE SOLVED: To provide a solid-liquid separator in which no clogging in filtrate discharging slits is caused, whose maintenance is easy, which has superior durability, and whose running cost is low. <P>SOLUTION: A lot of outer rings 21 and inner rings 22 are alternately arranged around a screw conveyer 3 so as to surround the conveyer 3 rotatably disposed, by providing specified spaces to form the filtrate discharge slits 2a between the respective rings 21 and 22. The outer rings 21 and inner rings 22 are integrally connected respectively, and are connected to driving mechanisms 7, 8, to make the outer rings 21 and inner rings 22 reciprocatingly turn in a reverse direction to each other. By this configuration, water in sludge transferred by the screw conveyer 3 is continuously discharged through the slits 2a to the outside, shearing force is applied to solid intruded into the slits 2a, the solid is not retained inside, and clogging is not caused. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
