A centrifugal separation container which is revolved around a rotation axis, includes: a separation part which includes a distal region which is disposed on a distal side than a liquid-to-be-treated supply port and a proximal region which is disposed on a proximal side than the liquid-to-be-treated supply port, with respect to the rotation axis, and in which a liquid-to-be-treated discharge port is provided in the proximal region; and a recovery part which is disposed on a distal side than the distal region with respect to the rotation axis, communicates with a distal end portion of the distal region through a communication path, and is filled with a recovery liquid for dispersing dispersoids that are to be centrifuged in a liquid to be treated.

A centrifugal separator has a stationary casing and a centrifuge rotor, which is provided in the stationary casing and arranged to rotate around an axis of rotation at a rotary speed and which includes a plurality of nozzles for discharge of a product from the centrifuge rotor. The centrifugal separator includes a sensor device which includes a transfer element, which has a first part and a second part and which is configured to be mounted in such a way that the first part is located inside the stationary casing and outside the centrifuge rotor and that the second part is located outside the stationary casing. At least the first part of the transfer element has an elongated shape, a receiving head, which includes the first part of the transfer element. The sensor device further includes a sensor element, which is mounted to the second part of transfer element and which is configured to sense vibrations and/or shock pulses propagating from the receiving head to the sensor element, and an evaluation unit, which communicates with the sensor element for transmitting signals from the sensor element to the evaluation unit. The transfer element is mounted in the stationary casing, directed such that the end face of the receiving head faces the passing jets from the nozzles during rotation of the rotor. A centrifugal separator with such a sensor device is also disclosed.

This invention is directed to a centrifuge rotor, such as for use in a disc nozzle centrifuge, having a bowl including an improved positioning and orientation of discharge nozzles for facilitating tangential flow of fluid discharged therefrom relative to the rotor bowl.

An outlet nozzle (40) for a centrifuge bowl (60) comprises a nozzle insert (10) and a nozzle holder (30). The nozzle insert (10) can be exchangeably fixed, in particular clamped, in the nozzle holder (30), and the outlet nozzle (40) has a flow channel (11) which determines the exit angle (?) of the outlet nozzle (40), said flow channel (11) of the outlet nozzle (40) being formed, in particular, by the nozzle insert (10).

A separator includes a drum ejection passage control element and an intermediate ejection control element both mounted on a drum assembly. The drum ejection passage control element is moveable between a first position and a second position. In the second position a drum ejection passage is open for ejection of material from a maximum diameter of a separator volume, while in the first position the drum ejection passage control element blocks the drum ejection passage to prevent the ejection of material from the maximum diameter of the separator volume. An intermediate ejection path is formed in the separator, each extending from an intermediate ejection path inlet at an intermediate region of the separator volume to an intermediate ejection path outlet. The intermediate ejection control element is moveable to alternately open or close the intermediate ejection path for fluid communication to the separator volume.

A centrifugal separator has a rotary drum that is adapted to receive a product that can be separated into a light phase, a heavy phase, and solid sediments, a first outlet for the light phase, a closing device that opens and closes a second outlet for the heavy phase. The closing device has an electromagnetic actuator having a ferromagnetic element whereon a closing plug is mounted. The electromagnetic actuator has an electromagnetic coil that creates a magnetic field so as to attract the ferromagnetic element. A spring is connected to the closing plug so as to urge the closing plug to a closed position. The closing plug, the ferromagnetic element and the spring are connected to the rotary drum.

Methods of supervising and controlling an E-line position in a centrifugal separator are disclosed herein. Further a centrifugal separator is disclosed herein. The E-line positon is continuously calculating based on inter alfa, monitored density of light and heavy liquid phases, monitored pressure at outlet side of light and/or heavy liquid outlet passages. First and/or second valves are controlled to control the E-line position, based on the supervised E-line position
