Method for conveying, mixing, and leveling dewatered pulp prior to drying |
摘要 |
System for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. The system produces a consistent flow rate of pulp and uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. The system includes a rotating shaftless screw conveyor for mixing and conveying dewatered pulp. The system includes a belt conveyor. The pulp is deposited from the screw conveyor onto the moving belt conveyor through a chute. The system includes a rotary doctor. The pulp is leveled with the rotary doctor located above the belt conveyor to produce a substantially even rate of mass flow of pulp along a length of belt conveyor. Uniform and consistent quantities of pulp per unit time can then be fed from the belt conveyor to a pulp flaker that then translates into an even rate of pulp mass flow to the dryer.
