ABSTRACT:
A solid-liquid separating apparatus for obtaining a liquid component, for example, from a used solid-liquid mixture for reuse of the same, which includes a filtering member having a hollow cylindrical shape made of a hard porous material such as porous ceramics, sintered metal, layered metal net, sintered resin, unwoven cloth, and the like. The hard porous material is provided with continuous air holes and a device is provided for reducing the pressure in the inner hollow space of the filtering member during the rotation thereof. A scraper is provided for scraping a solid component remaining on the filtering surface of the filtering member after the liquid component is sucked into the inner space of the filtering member. The separating apparatus further includes a cutter for effectively removing the solid component and a device which allows reuse of the mixture with solid particles evenly distributed therein. The use of the hard porous material as the filtering member makes it possible to realize a smooth outer surface thereof without deformation to attain an even scraping operation, which results in an excellent filtering ability and improved durability of the apparatus itself.
