摘要： A centrifuge (2) includes a conveyor (12) including a hub (14) rotatable about an axis (34) and at least one helical blade (16) extending radially from the hub and in the axial direction of the hub. A bowl (4) extends about the conveyor and is rotatable about the axis. The bowl includes a cylindrical section (6) extending from an upstream end of the conveyor and a conically diverging screen section (10) extending to a downstream end of the conveyor. The bowl may also include a conically converging section (8). The conically diverging screen section includes an angle (40) that reduces the coefficient of friction of the solids to a point that allows the cake formed of the solids to slide in a controlled manner forward on the conically diverging screen section with minimal back pressure but without allowing the solid cake to break loose from the conically diverging screen section and slide out of the centrifuge in an uncontrolled manner. A method of separating solids from liquid of a slurry includes feeding a slurry from a conveyor hub to a cylindrical section of a bowl extending about the conveyor hub; scrolling the solids along the cylindrical section in a first direction and a majority of the liquid in a second direction opposite the first direction using at least one helical blade extending from the conveyor hub; and sliding the solids from the cylindrical section along a conically diverging screen section of the bowl that reduces the coefficient of friction of the solids to a point that allows the cake formed of the solids to slide in a controlled manner forward on the conically diverging screen section with minimal back pressure but without allowing the solid cake to break loose from the conically diverging screen section and slide out of the centrifuge in an uncontrolled manner.
摘要翻译：离心机（2）包括输送机（12），该输送机（12）包括可围绕轴线（34）旋转的轮毂（14）和至少一个螺旋叶片（16），所述螺旋叶片从轮毂径向延伸并且沿轴向方向延伸。碗（4）围绕输送机延伸并且可围绕轴线旋转。所述碗包括从所述输送机的上游端延伸的圆柱形部分（6）和延伸到所述输送机的下游端的锥形发散的筛分部分（10）。碗也可以包括锥形会聚部分（8）。锥形发散屏幕部分包括角度（40），该角度（40）将固体的摩擦系数降低到允许由固体形成的饼块以受控的方式在最小的背压下在锥形发散的筛分部分向前滑动，但没有允许固体滤饼从锥形发散的筛分部分松脱，并以不受控制的方式从离心机中滑出。从浆料的液体中分离固体的方法包括将浆料从输送轮毂输送到围绕输送机轮毂延伸的碗的圆柱形部分; 使用从传送轮毂延伸的至少一个螺旋叶片沿第一方向沿着圆柱形部分沿着第一方向和大部分液体在与第一方向相反的第二方向上滚动固体; 并且沿着碗的锥形发散的筛网部分从圆柱形部分滑动固体，其将固体的摩擦系数降低到允许由固体形成的饼块以受控方式在锥形发散的筛网部分上向前滑动的点具有最小的背压，但不允许固体饼从锥形发散的筛分部分松开并以不受控制的方式从离心机中滑出。
