摘要:
A method and apparatus for separating solids from liquid containing same comprises a conical-mesh which rotates within a casing about a vertical axis with the mesh walls upwardly diverging. A liquid-solid slurry is introduced to the center of the mesh at a top inlet. Stationary wiper arms in the center of the mesh, along with fluid pressure inside the mesh, pumping effect of the rotating blades, gravity force on the slurry and tangential pump suction at the bottom drive the liquid out through the mesh, while the solid material passes down through a central outlet opening in the bottom of the mesh.
摘要:
A method and apparatus for separating solids from liquid containing same comprises a cylindrical casing within which a rotor assembly or block having a conicalmesh rotates about a vertical axis with the mesh walls upwardly diverging. A liquid-solid slurry is introduced tangentially to the inside of the mesh at a top inlet. Stationary wiper arms inside the mesh remove the solids from the mesh as it rotates. Fluid pressure inside the mesh, pumping effect of the rotating blades, gravity force on the slurry and particularly tangential pump suction at the bottom of the casing, drive the liquid out through the mesh, while the solid material is expelled vertically downwards through a central outlet opening in the bottom of the mesh.
摘要:
A method for preparing a ceramic suspension using alpha-Al.sub.2 O.sub.3 powder containing agglomerated powder particles includes dissolving ionic or polymeric reagents as additional dispersing agents in water or an organic solvent as a dispersion medium. Alpha-Al.sub.2 O.sub.3 powder is added thereto while being stirred. Ceramic molded articles may be produced from the suspension.
