摘要： This application discloses a method and system to extract the maximum amount of fluid product from a conical-bottomed vessel, wherein sediment settles to the bottom of the conical-bottomed vessel. The application further discloses a system using a restrictor tee conduit configured to use the Venturi Effect to create a vacuum to draw sediment and other solids from the conical-bottomed vessel section into fluid product coming from the side outlet of the conical-bottomed vessel. The extracted mixture of fluid product and solids is then sent to a centrifuge for separation.

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.
