Definitions
- the invention relates to a device for mixing drilling media, in particular for producing a drilling suspension from powdered bentonite or other drilling additives and / or additives and water, and claims the priorities of German patent applications 101 15 560.3 and 101 33 181.9, to which the content refers is taken.
- liquid or gaseous drilling media are used to remove the soil, to support the removal with the help of drilling tools, to cool them and, in particular, to remove the cuttings.
- a common drilling medium is made from the clay mineral bentonite, which is commercially available in powder form, and water. Since the mixture of water and bentonite but also many other drilling additives is a suspension, the drilling medium is usually prepared as soon as possible for the planned drilling process. Unused or premixed drilling suspension tends to form two phases so that it must be re-mixed before use. For this purpose it is known to use agitators and other mixing devices.
- the object of the invention is to create a device which allows improved mixing of a drilling medium and to provide a corresponding method.
- the invention is not limited to the use of certain drilling media or drilling additives. Rather, the invention can be used to manufacture any drilling media.
- a mixture of a gas and a liquid (mist / foam) is also conceivable, for example.
- the main idea of the invention is to generate a vacuum with the aid of compressed air and to suck in at least one component of a drilling medium with the aid of this vacuum and then to transport the component sucked in with the aid of the suction air.
- bentonite powder or polymer powder is used as an ingredient (drilling additive).
- the device according to the invention can have a suction device, which is preferably designed as an air suction nozzle.
- the mixing nozzle is designed as a Venturi nozzle and can have an inlet nozzle and an outlet nozzle as well as an intake opening arranged therebetween for the drilling additive.
- the drilling additive or the sucked-in component of the drilling medium is preferably mixed downstream, for example with water, behind the mixing nozzle.
- the device according to the invention can be placed in a handy form consisting of a nozzle with a compressed air connection and a suction nozzle and a suction hose on a water container, wherein the mixing nozzle can have a mixing lance for introducing the drilling additive into the water in the water container.
- the suction hose can then be led to a bentonite reservoir, for example a container with bentonite powder, and the powder can be introduced into the water in the container through the negative pressure that is created via the suction line and the mixing lance. Due to the air swirling in the mixing nozzle, not only is the powder in finely atomized form introduced into the water, but at the same time it is mixed in the water tank due to the air swirling caused by compressed air.
- Fig. 1 a schematic representation of the device according to the invention
- Fiq.2 a longitudinal section through the mixing nozzle according to the invention
- Fig. 3 a cross section along the line III-III in accordance with FIG. 2;
- Fig. 4 a further embodiment of the mixing nozzle according to the invention.
- Fig. 5 a cross section along the line V-V according to Fig.4.
- a mixing nozzle 1 has a compressed air connection 2, an intake connection 4 and a lance connection 6.
- a suction hose 12 is located on the intake connection for sucking in a drilling additive.
- the mixing nozzle also has an inlet nozzle 20, a vacuum chamber 22 and an outlet nozzle 24.
- the mixing lance 16 is placed on the lance nozzle 6 and inserted into the liquid container 18 with the drilling medium or with water.
- the mixing nozzle is connected to the pressure medium source 8, such as a compressor, for example, by means of the compressed air hose 10 via the flow connection 2.
- the suction hose 12 for the drilling additive is connected to the suction nozzle 4.
- vacuum chamber 22 arises due to the fact that it enters and leaves the inlet nozzle 20 24 emerging air flow a negative pressure, which causes a suction process in the suction hose 12.
- a drilling additive such as a powder or a liquid or a gas located in an additional drilling container 30, can now be sucked in.
- the mixing nozzle can also have a plurality of intake ports (FIG. 3).
- the device according to the invention can be used to mix the drilling medium located in the liquid container 18 by circulating the drilling medium via the suction hose 12 or 13.
- the mixing lance 16 can also be used to bring the "longer" finished drilling suspension back into a homogeneous mixing state.
