The utility model relates to the technical field of white
carbon black production, and discloses a white
carbon black synthetic liquid washing and
dewatering device which comprises a tank body and supporting legs fixed at the bottom of the tank body, a tank cover is arranged on the right side of the tank body,
extrusion mixing assemblies are arranged in the tank body and on the left side of the tank body, a water inlet
pipe is arranged on the top of the tank body, and a water outlet
pipe is arranged on the water inlet
pipe. According to the washing and
dewatering device for the white
carbon black synthetic liquid, through the arranged extruding and mixing
assembly, an electric push rod is started, the electric push rod can drive a pressing disc and a
rotating disc to move left and right in the tank body, and in the left-right moving process of the pressing disc and the
rotating disc, an inserting rod slides in a spiral sliding groove in the surface of a rotating rod; the rotating rod drives the
rotating disc to rotate, the rotating disc drives the shifting piece to rotate, the interior of the tank body is stirred,
solid white carbon black is effectively prevented from being deposited and accumulated, the washing effect is not influenced, and in the filter pressing process, the shifting piece can be completely embedded into the rotating disc, so that
normal filter pressing operation is not influenced.
