The present disclosure provides a fixed cylinder centrifuge, including a base, a driving device, a screw propeller, a liquid inlet pipe, and a fixed cylinder. The fixed cylinder includes a straight cylinder and a conical cylinder. The straight cylinder and the conical cylinder are communicated with each other and are connected to each other through a first flange. Sand discharging holes are formed in the tail end of the conical cylinder. The screw propeller is rotatabh arranged in the straight cylinder and the conical cylinder and includes a central pipe and a blade. The blade is spirally welded on a pipe wall of the central pipe in an axial direction. A tiny spacing is reserved between the tail end of the blade and the inner wall of the straight cylinder and between the tail end of the blade and the inner wall of the conical cylinder.

A centrifugal separator for cleaning a gas containing liquid impurities includes a stationary casing including a surrounding sidewall, a first end wall and a second end wall which enclose a space through which a gas flow is permitted. The space includes an upper separation chamber and a lower discharge chamber. The separator further includes an inlet extending through the stationary casing and permitting supply of the gas to be cleaned to the separation chamber, a rotating member including a stack of separation discs and being arranged to rotate around an axis of rotation, wherein the stack of separation discs is arranged in the separation chamber and a drive member for rotating the rotating member. The discharge chamber is arranged axially below the stack of separation discs such that clean gas and separated liquid impurities both enter said discharge chamber after being separated in said stack of separation discs, and further, the separator includes a gas outlet configured to permit discharge of cleaned gas from said stationary casing, wherein the gas outlet includes an outlet opening through the stationary casing and a portion extending from the outlet opening into the discharge chamber. Further, there is a drainage outlet arranged in said discharge chamber and configured to permit discharge of separated liquid impurities from said stationary casing.

A separator for centrifugally processing a flowable product includes a rotatable drum bounding a centrifuging chamber. The drum has a feeding and removal system having at least one feeding device and one or more removal devices composed of plastic or a plastic composite. An inner drum, composed of plastic or a plastic composite, is arranged in an outer supporting device of the drum. The feeding device and the one or more removal devices extend into the inner drum, do not rotate with the inner drum during operation, and are glued and/or welded to each other in such a way that the feeding device and the one or more removal devices are sealingly connected. The feeding and removal system has one or more grippers as the removal device, each of which one or two or more grippers has a disk segment and a shaft segment.

The present invention relates to a method for separating lymphocytes and/or stem cells from whole blood in an automated blood separation system, wherein the quality of the collected lymphocytes and/or stem cells fractions is increased and the cell collection procedure is further automated by use of an optical sensor comprised in a detector device to measure turbidity and colour in the claimed method and in a cell separator, which can be used to perform the claimed method. The method of the invention is particularly useful to collect lymphocytes and/or stem cells fractions from whole blood, wherein the contamination of the collected cell fractions by platelets, red blood cells and granulocytes is reduced.

A centrifugal separator includes a rotating body driving and sealing structure in which a hermetically sealed space is formed between a rotating body and an outer case by sealing the inside and outside using a noncontact seal during rotation of the rotating body, in an airtight manner. A rotation coupling unit is provided at the upper end of a centrifugal cylinder, and even when the centrifugal cylinder is deformed during use causing an internal fluid to leak through a fitting portion of a bottom member to the centrifugal cylinder, the fluid leaks in the hermetically sealed space so that the driving system or the like is not contaminated.

An exchangeable separation insert for a centrifugal separator includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged, and first and second stationary portions. A feed inlet supplies a fluid mixture to the separation space. The insert includes a light phase outlet and a heavy phase outlet. The feed inlet is arranged at a first axial end of the rotor casing. One of the light phase outlet and heavy phase outlet is arranged at a second axial end. A first rotatable seal seals and connects the feed inlet and a second rotatable seal seals and connects one of the light phase outlet and heavy phase outlet.
