Definitions

  • the invention relates to a weir for solid jacket centrifugal drums, with at least one passage for draining a liquid phase separated in the centrifugal drum, the weir being assigned an axially displaceable throttle disc.
  • Such a weir is known for example from JP 57-194 061 A2. This weir is used to regulate the amount of solids running out of the centrifugal drum in order to achieve a desired solids concentration.
  • the weir rotates with the centrifugal drum and is connected to a stationary, axially displaceable part via a bearing point. This bearing point must be sealed against the liquid phase flowing off.
  • Such solutions are structurally complex and can be prone to failure.
  • the present invention has for its object to provide a weir that allows a continuous adjustment of the liquid level in the centrifugal drum without having to transmit actuating forces to rotating parts.
  • the throttle disk is designed as a stationary part and is provided on the passage for a clarified liquid phase, so that an adjustment of the liquid level in the centrifugal drum is made possible by an axial displacement of the throttle disk.
  • the stationary throttle disc does not adversely affect the operation of the centrifugal drum.
  • an originally expected braking effect occurred due to the liquid passing through the annular gap between the rotating weir and the stationary throttle disc.
  • the annular gap creates a flow resistance that is greater the smaller the axial distance between the weir and the throttle plate.
  • a greater liquid pressure at the passage is required, which leads to an increase in the liquid level in the centrifugal drum. If the axial distance between weir and throttle plate is increased, the liquid level in the centrifugal drum drops to a value which is caused by the passage of the weir in a known manner.
  • the throttle disk is advantageously axially displaced by a hydraulic, pneumatic or mechanical device, the latter being able to include, for example, a threaded bushing.
  • the passage is formed by a plurality of grooves which start from the inside diameter of the weir.
  • the shape of the grooves allows the length of the trailing edge to be predetermined for the liquid.
  • the cross-section for the liquid flowing out of the centrifugal drum is the product of the active length of the trailing edge and the distance between the weir and the throttle plate.
  • a further advantageous embodiment is characterized in that the passage is formed by a plurality of openings which are provided in the wall of the weir and which can have a circular, rectangular or square cross section.
  • the centrifugal drum which is provided on the liquid outlet side with a weir 2 which has a passage 3 which is formed by a plurality of grooves 4 extending from the inside diameter of the weir or by openings 5 provided in the wall of the weir can.
  • the passage 3 is assigned a stationary throttle disc 6, which is axially displaceable via a threaded bushing 7.
  • the distance between the weir 2 and the throttle plate 6 can be changed by rotating the threaded bushing 7.
  • the change in the discharge cross-section causes a change in the liquid level in the centrifugal drum 1 so that a stepless setting this liquid level is made possible by displacement of the throttle disc 6.
