Abstract
The utility model discloses a spiral discharging centrifuge, comprising a rack, a material feeding pipe, a drum and a spiral material conveyor. A cavity chamber is disposed in the spiral material conveyor; the material feeding pipe is disposed on the drum and passes through the cavity chamber; an inflation pipe is disposed in the material feeding pipe and penetrates the material feeding pipe; the drum is provided with first baffle plates, second baffle plates, and third baffle plates; a conical portion of the drum is provided with fourth baffle plates; and the first baffle plates, the fourth baffle plates, a light liquid phase surface and a drum shaft axis form a pressure cavity.
