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： In a system for combined centrifugation and microfiltration, retentate from a cross-flow microfilter is fed to an automatic piston discharge centrifuge for solids removal, thereby enhancing the efficiency of both processes. The centrifuge 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 coupled to a piston actuator by a two-part piston shaft. During the feed mode of operation, the piston shaft is disconnected, the piston is held in an uppermost position by hydraulic pressure from the feed liquid, and a centrate valve on the piston is urged open to permit the centrate to flow out to a centrate discharge port. In a solids discharge 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.
