摘要： In a centrifugal rotor (1) for separation of a substance from a liquid mixture supplied to the centrifugal rotor there is delimited a separation chamber (7) having peripheral outlets (30). The centrifugal rotor comprises an outlet device (20-28) for intermittent opening and closing of said outlets (30) during rotation of the centrifugal rotor. An actuation device (31-40) may cause the outlet device (20-28) to keep the outlets (30) open to a varying extent and/or during a varying time, and a control device (43) is adapted to control the actuation device (31-40) in response to a sensed value of the amount of mixture supplied to the rotor, such that a predetermined amount of separated substance (29) having collected in the separation chamber (7) is discharged through the outlets (30) each time these are opened and closed.

摘要： A method for adjusting an interface between a specific light liquid phase and a specific heavier liquid phase to a wanted radial level in a centrifugal separator, in which the separation chamber (5) is emptied and the inlet opening (23, 29) of a discharge device (21, 29) in an outlet chamber (17) for the heavy liquid phase is brought to a radial inner position. Then a pre-determined volume of the specific heavier phase is supplied to the separation chamber (5) and the mixture is supplied to the separation chamber (5), the interface formed between the two liquid phases being displaced radial outwardly and the displaced specific heavier liquid phase being pressed radial inwardly in the outlet channel (18) and into the outlet chamber (17). A first indicating means (26) indicates when the separation chamber (5) has been filled up and the inlet opening (23, 29) is moved towards the free liquid surface in the outlet chamber (17) until specific heavier liquid phase is discharged through the inlet opening (23, 29) and the discharge channel, which is indicated by means of the second indicating means (27). The inlet opening (23, 29) is prevented from moving at least radially outwardly from its obtained position corresponding to a wanted position of the interface. During the following normal operation the radial level position of the interface is maintained.

摘要： A mixer for liquid or suspensions comprises two mixing chambers (2, 3) provided each with an outer inlet (10, 12). The chambers are connected to each other in such a way that the first chamber (2) leads to the second chamber (3). A number of mixing elements (6, 7) are arranged on a rotating axis (5) which is common for the two chambers. The mixing elements have different shapes in the two chambers. In the first chamber (2) the mixing elements are arranged to achieve a mixing by means of large shear forces. In the second chamber the mixing elements are arranged to achieve a mixing by stirring mainly without shear forces. A method for continuous mixing comprises mixing a little amount of a first liquid with a considerably larger amount of a second liquid in a first mixing chamber in which the mixing takes place by way of high shear forces. The obtained mixture is subjected to mixing by stirring mainly without shear forces in a second mixing chamber.

摘要： Upon use of a nozzle centrifuge for separating oil, water and sand from a mixture thereof separated water and sand is continuously removed through nozzles (12), which are arranged at the periphery of the rotor of the nozzle centrifuge. Separated oil is discharged through a central outlet (13-15) in the rotor. Through a space (17) in the rotor, which communicates with the radially outer part (7b) of the rotor separating chamber (7), water may either be supplied under pressure to the rotor or be discharged from the rotor for maintaining an interface layer, which is formed in the separating chamber (7) between separated oil and separated water, at a predetermined radial level (22). A supply device (23-25) and a discharge device (26, 27) are adapted to supply to the rotor and discharge from the rotor, respectively, only so much water that is required for said purpose. The discharge device (26, 27) is separated from the supply device (23-25), so that discharged water need not be subjected to the pressure generated by or maintained in the supply device (23-25).
