Weir device for affecting a centrifuge for treated liquid uses an outlet in a rotating centrifugal drum via a weir running round the drum with axial adjustment of a throttle to affect the outlet's axial width and change pond depth.

摘要

Treated liquid passes out through an outlet (13) from inside a rotating centrifugal drum (2) via a weir (20,20') running round the drum. This outlet is between the weir and an axially adjustable throttle element (12) allocated to it. Axial adjustment of the throttle affects the axial width of the outlet and changes pond depth within the centrifugal drum.
