Abstract:
A washer for washing a fiber suspension associated with a fiber stock preparation system, said washer consisting essentially of:a plurality of rolls; a porous fabric carried by said plurality of rolls in a closed loop, said closed loop including a lower run defining a washing zone, said porous fabric moving in a running direction through said washing zone, said porous fabric having an upper surface in said washing zone for carrying the fiber suspension thereon; a headbox positioned within said closed loop and above said porous fabric at an upstream end of said washing zone, said headbox configured for discharging a fiber suspension to be washed onto said upper surface of said porous fabric; an accept removal device positioned within said closed loop and above said porous fabric at a downstream end of said washing zone, said accept removal device being configured for actively removing the fiber suspension from said upper surface of said porous fabric; a plurality of showers positioned within said closed loop and above said porous fabric in said washing zone between said headbox and said accept removal device; and a plurality of dewatering elements positioned below said porous fabric in said washing zone, each said dewatering element being configured for removing water from a bottom surface of said porous fabric.
