摘要： The invention relates to a solid-wall centrifuge, comprising a spinner drum (1), rotating about a horizontal rotational axis, with a weir for letting off a fluid from the spinner drum (1), which has a passage with at least one or more passage openings (5) in an axial end region or drum cover (3) and preferably a throttle disc, arranged outside the spinner drum (1) before the through openings (5), the separation of which from the at least one through opening (5) may be altered, such that between the passage (4) and the throttle disc (6) or a further component, an adjustable annular gap (8) is embodied, characterised in that the annular gap (8) is enclosed by a deflector plate (12) which extends away therefrom in, for example, a conical form.

摘要： The invention relates to a three-phase solid-wall helical centrifuge and method for operation of a three-phase solid-wall helical centrifuge with a first internal weir (15), relative to the drum longitudinal axis, for drawing off a first light liquid phase (L1) and a second external weir (17), for drawing off a second heavier liquid phase (L2) from the spinning drum (3), characterised in that the second weir (17) comprises a through opening (37) provided with a throttling device (35) the separation of which from the through opening (37) may be altered.

摘要： A three-phase solid bowl screw centrifuge has a rotatable drum (1) and a screw (2) arranged in the drum (1). In this case, at least one solid material discharge is arranged at one axial end of the drum (1) and at least two or more liquid outlets for liquid phases of different densities - a lighter liquid phase and a heavier liquid phase - are arranged at its other axial end. The one liquid outlet also has a skimmer disc and the other liquid outlet is formed as an overflow weir, the skimmer disc being preceded by two regulating discs (11, 12) of the same inside diameter, which extend radially from the outside inwards and between which there enters a siphon disc (13), which in the skimming chamber (10) extends from the inner circumference of the latter outwards. This has the effect of forming an annular chamber (14), which is assigned a means for changing the pressure in the annular chamber (14).
