Definitions
- the invention relates to a vortex jet nozzle which is designed as a hydraulic working tool.
- Such known tools which can be used in particular for cleaning pipes or containers, are e.g. consisting of an inner stand which can be connected to a high-pressure medium source and which has a central bore and a rotor which is arranged centrally around the outside and has pressure medium outlet channels and can be driven by the pressure medium.
- the object of the invention is therefore to provide a structurally simple tool, if possible with smooth outer surfaces, which can be operated reliably and which does not require bearings or seals, so that it can also be used to clean clogged narrow hollow bodies, in particular pipes a high pressure medium as well as for drilling holes in soft masses, e.g. soft stone and soil.
- the device should also be able to be operated at very high speeds and very high pressures.
- the sleeve-shaped rotor which is arranged directly above a tapered pin of the stator and which is supported on the stator side, preferably via an annular disk made of plastic or the like pushed over the pin of the stator, on an end face of an enlarged area of the stator, is axially secured by at least one pin engaging tangentially in a circumferential groove in the journal and mounted in a transverse bore in the rotor.
- the vortex jet nozzle shown in Fig. 1 includes the rotor 1, which is designed as a front and radial radiator and is arranged on a stand 2. In the interior of the stator 2 there is a central bore 3 through which the pressure medium is supplied.
- the rotor 1 has a V-groove 19 on the end face, into which outlet openings of nozzle inserts 18 open, so that intersecting jets emerge therefrom, by which it can be achieved with certainty that solid deposits in the interior of a tube are released.
- the point of intersection of the pressure medium jets emerging from the side surfaces of the V-shaped groove 19 is preferably in the region of the end face of the rotor 1 or outside in front of it.
- the nozzle inserts 18 are arranged off-center, so that thereby a rotary movement of the rotor 1 on the stand 2 is achieved.
- the rotor 1 can furthermore have nozzle inserts 18 in the middle of its longitudinal region, from which jets radially emerge. These are also suitably arranged so that a rotational movement of the rotor 1 relative to the stator 2 is achieved.
- the tool can only be operated with one of the nozzle groups or only with a single nozzle. In the latter case, the remaining nozzle inserts 18 can be replaced by sealing plugs which are screwed into the corresponding pressure medium outlet channels.
- the stand 2 has at its rear end (bottom in FIGS. 1 and 2) a connection thread 20, for example for a high-pressure medium hose.
- a connection thread 20 for example for a high-pressure medium hose.
- the cylindrical housing of the stand 2 is flattened for the attachment of a tool when fastening the high-pressure medium hose.
- Cross bores 16 extend from the central bore 3, which has the connecting thread 20, and open in front of an annular space 17 provided in the interior thereof when the rotor 1 is placed on the stand 2. From this, pressure medium outlet channels 4 lead on the one hand to the nozzle inserts 18 in the V-groove 19 and to the pressure medium outlet openings 15 in front of the end face 7 at the enlarged area 8 of the stand 2 or in front of an annular disk 6 made of plastic or the like in front of it.
- pressure medium outlet channels 4a lead from the annular space 17 to radially inserted nozzle inserts 18, as shown in FIG. 6. 5, the pressure medium outlet channels 4 run according to the line AA parallel to the radius of the rotor 1, but offset laterally for this purpose.
- a circumferential groove 9 is provided on a pin 5 of the stator 2 extending into the rotor 1.
- a pin 11 is inserted tangentially through the transverse bore 10 indicated in FIGS. 5 and 8 in the rotor 1 for axially securing the rotor 1 on the stator 2.
- FIGS. 5, 7 and 8 show, it is furthermore
- a pressure relief opening 12 is provided in the rotor 1 adjacent to its inner bottom surface 14. This prevents a pressure from building up in front of the end face of the pin 5 which could lead to the pin 11 tearing in the transverse bore 10.
- the pressure medium outlet channels 4 to the nozzle inserts 18 arranged in the V-groove 19 and to the pressure medium outlet openings 15 opening in front of the enlarged area 8 of the stator 2 or in front of the annular disc (6) are expediently designed as straight lines extending longitudinally through the rotor 1.
- rotor 1 and stator 2 are designed as rotating bodies.
- the stator 2 may have a larger diameter than the rotor 1. This is necessary if e.g. the stator 2 serves as a guide for the tool in narrow pipes so that the radial jet can form on the rotor 1 at all.
- the rotor 1 can receive a hardened jacket made of steel, since otherwise the jacket wears too quickly when used as a drilling tool in overgrown pipes.
- the core of the rotor 1 is preferably made of bronze, so that when it is switched off, when there is no more water, there is no seizing on the stand 2.
- the stand 2 can optionally be equipped in a known manner with recoil nozzles, so that the tool can automatically work through a line or through a bore.
- the stand 2 can also be provided with a feed part or be structurally combined with it, which has diagonally directed rearward nozzles which are connected to the central pressure feeder 3.
- All nozzle inserts 18 are inserted into the pressure medium outlet channels, in particular screwed in, in such a way that they do not protrude beyond the outer contours of the rotor 1 and thus damage is impossible.
- the nozzle inserts 18 preferably have an external thread on their circumference, which may be glued to the rotor 1, and a square or a hexagon on the radiation exit side. Rectifiers in the form of intersecting plates can be used before each nozzle insert.
- the nozzles can be designed such that the torque of the radial nozzles is opposite to the torque of the front nozzles and is also larger, so that the front nozzles are inevitably rotated counter to their torque. This increases the cleaning effect considerably.
