Abstract
The invention relates to a device and to a method for the hydrodynamic removal of dense materials from a suspension, said device comprising a hydrocyclone (1), which holds the suspension, a classifying tube (2), which adjoins the hydrocyclone, and a storage chamber (3), which holds the removed dense materials, wherein a flushing water flow to the classifying tube (2) and a flushing water flow to the storage chamber (3) are provided, which can be controlled in a closed-loop or open-loop manner by means of a control element provided at the feed to the classifying tube and a control element provided at the feed to the storage chamber, respectively.
Claims20
An apparatus for the hydrodynamic removal of dense material from a slurry, comprising:
- a hydrocyclone that receives the slurry,
- a classifying tube adjoining the hydrocyclone, and
- a separate storage chamber that receives dense materials that have been separated out from the slurry,
- a flow of flushing water to the classifying tube controlled via a control circuit, the control circuit comprising an actuator, a flow of flushing water to the storage chamber controlled via the actuator, the control circuit also comprising at least one sensor being positioned to detect a filling level of the dense materials and a flushing water overflow of the storage chamber.
A method for the hydrodynamic removal of dense material from a slurry, comprising:
- delivering slurry to a hydrocyclone,
- separating out dense materials from the slurry for conveying the separated out dense materials into a classifying tube into which flushing water is introduced for further separation,
- sedimenting the dense materials that are separated in a separate storage chamber, and
- delivering a flow of flushing water to the classifying tube in a controlled manner by means of a control circuit, the control circuit comprising an actuator and a sensor, a detected filling level of the storage chamber detected by the sensor in order to flood the storage chamber with flushing water in a controlled manner based on the detected filling level.
