摘要： A hermetically sealed solids discharge centrifugal separator exhibits low-shear filling, acceleration, and separation of feed material. The separator can be particularly useful for separation and recovery of sensitive solids such as chemical or biological substances. The separator accommodates disposable sample contacting elements to eliminate the need for clean-in-place and sterilize-in-place operations. Some embodiments of the separator feature dual solids discharge pistons, which fully optimize recovery of valuable solids.

摘要： A centrifugal separator includes a cylindrical bowl having a conical lower end with an opening through which feed liquid is injected during a feed mode of operation. During the feed mode, solids separate from the feed liquid and accumulate along the inner surface of the bowl as the bowl rotates at high speed. After accumulation of the solids, the rotation of the bowl is stopped and residual liquid is drained by gravity from the bowl. In a solids discharge mode of operation, a piston of a piston assembly is urged downward along a vertical axis in response to fluid such as compressed gas or hydraulic liquid. The downward movement of the piston forces accumulated solids from the bowl via the opening in the conical lower end thereof . The solids pass from the bowl and into a passage leading to an outlet port, where the solids exit the separator.

摘要： In a system for combined centrifugation and microfiltration, retentate from a cross-flow microfilter (201) is fed to an automatic piston discharge (APD) centrifuge (210) for solids removal, thereby enhancing the efficiency of both processes. A solids-containing suspension (207) is fed into a tank (202) and then pumped (203) to a microporous membrane filter to decide whether to return the retentate (236) to the microfilter (201) or to divert the retentate by means of a valve (235) as feed (230) to the APD centrifuge (210). A turbidity or density meter (220) also can be installed on the centrate output of the APD centrifuge (210) to indicate when the APD bowl is full of solids, or to control a centrate pump (222) and to decide whether to return (224) the centrate to the retentate tank (202) by means of a valve (223) or to discharge (228) the centrate from the system. The APD centrifuge (210) includes a cylindrical bowl having a conical lower end with an opening through which feed liquid is injected. Solids separate from the feed liquid and accumulate along the inner surface of the bowl as the bowl rotates at high speed. A microfiltration membrane can be added to improve solids retention in the bowl and provide a filtered centrate. During solids discharge, a piston is urged downward along a vertical axis.. The downward movement of the piston forces accumulated solids from the bowl via the opening in the conical lower end thereof.

摘要： A centrifugal separator includes a cylindrical bowl having a conical lower end with an opening through which feed liquid is injected during a feed mode of operation. The feed liquid is separated, into centrate and solids, which accumulate along the inner surface of the bowl. A piston assembly includes a conical piston disposed within the cylindrical bowl, coupled to a piston actuator by a two-part piston shaft. During the feed mode of operation, the piston shaft is disconnected, and the piston is held in an uppermost position by hydraulic pressure from the feed liquid as the bowl is rotated, and a centrate valve on the piston is opened to permit the centrate to flow out to a centrate discharge port. After solids are separated and accumulated on an interior surface of the bowl, the rotation of the bowl is stopped and residual centrate is drained therefrom. In a solids discharge and pumping mode of operation, the piston shaft is connected and the piston actuator urges the piston axially downward, closing the centrate valve and forcing the accumulated solids from the bowl via the opening in the conical lower end of the bowl and into a passage leading to a solids outlet port.
