Claims14
A metering apparatus for introducing a powdery medium into a fluid, comprising
- a mixing vessel constructed to be filled with the fluid, and
- a metering unit for the powdery medium, wherein the metering unit comprises a first inlet for the powdery medium, a second inlet for a compressed gas, and an outlet extending into the mixing vessel for discharging the powdery medium and the compressed gas into the mixing vessel.
A mixing plant for mixing a fluid with a powdery medium to produce a drilling fluid, the mixing plant having a pump and a metering apparatus, with the metering apparatus comprising:
- a mixing vessel constructed to be filled with the fluid and connected with a water supply, and
- a metering unit for the powdery medium connected with a bentonite supply, wherein the metering unit comprises a first inlet for the powdery medium, a second inlet connected with a compressed gas supply for a compressed gas, and an outlet extending into the mixing vessel for discharging the powdery medium and the compressed gas into the mixing vessel.
A method for introducing a powdery medium into a fluid, comprising the steps of:
- mixing the powdery medium with a compressed gas flow, and
- blowing the compressed gas flow together with the powdery medium into the fluid.
