Definitions

  • the invention relates to a rotor nozzle for a high-pressure cleaning device with a housing, a rotor rotatably mounted therein and rotated by the cleaning fluid and with a nozzle arranged downstream of the rotor, the outlet axis of which includes a variable acute angle to the axis of rotation of the rotor and which is rotated by the rotor in such a way whose axis of rotation is rotated so that the emerging jet of cleaning liquid rotates on a cone jacket.
  • Such a rotor nozzle is known from German Patent 36 23 368. It enables a point jet to be emitted which revolves on a cone shell, the angle of the cone shell being able to be widened as a function of the speed in the known rotor nozzle.
  • stops By adjusting the stops, it is possible to limit an inclined position of the nozzle and thus an increase in the opening angle of the cone shell, the operator being able to move these stops in the housing of the rotor nozzle, so that the stops then have a differently wide inclination of the nozzle outlet axis compared to the rotor axis of rotation.
  • a rotor nozzle with a stilt which receives the nozzle and is supported with a spherical end in a pan which is open in the middle and held on the housing, while at the other end a driver connected to the rotor and arranged at a radial distance from the rotor axis engages it is particularly advantageous if the stop surrounds the stilt concentrically to the axis of rotation of the rotor, is adjustable in the direction of the axis of rotation of the rotor and forms a circumferential contact edge lying on the outside of the stilt.
  • the stop in the housing is axially displaceable and rotatably mounted with respect to the axis of rotation of the rotor and is screwed into a threaded bore of an adjusting sleeve arranged coaxially to the axis of rotation of the rotor, which is axially immovable in the housing and freely rotatable with respect to the axis of rotation of the rotor is.
  • an adjusting sleeve arranged coaxially to the axis of rotation of the rotor, which is axially immovable in the housing and freely rotatable with respect to the axis of rotation of the rotor is.
  • the driver carries a radial groove in which the stilt is immersed with a driving pin.
  • the adjustment sleeve can close the front of the housing and support the pan for storing the stilts. In this way, the adjusting sleeve practically forms part of the housing, the two housing parts being rotated relative to one another about the longitudinal axis of the housing in order to achieve a change in the beam opening angle.
  • a closable bypass line also exits from the interior of the housing located upstream of the nozzle into the region of the rotor nozzle located immediately downstream of the nozzle.
  • part of the cleaning liquid is guided past the nozzle, so that the pressure of the point jet emerging from the nozzle can be varied.
  • This pressure variation is also supported by the fact that the amount of liquid carried past the nozzle in the bypass re-enters the point jet in the region downstream of the nozzle, thereby tearing it open and fanning it out. Overall, this results in a less sharply focused point beam with a lower exit speed and therefore with a lower impact speed.
  • bypass line comprises a plurality of bypass channels surrounding the nozzle, which are preferably all constructed identically.
  • the effect of the liquid bypassing the nozzle is particularly advantageous if the bypass line emerges from its wall in a funnel which immediately adjoins the nozzle and widens conically in the direction of flow, in particular if the bypass line essentially extends in a direction perpendicular to the axis of rotation of the rotor arranged radial plane enters the funnel, ie essentially perpendicular to the beam direction.
  • the amount of liquid emerging through the bypass line is deflected in the direction of the point jet and entrained by it, so that there is a coating of the sharp core of the point jet which, until it hits an area to be cleaned, is fanned out to form an essentially homogeneous one Beam leads.
  • metering valves are arranged in the bypass line, the position of which can be adjusted by adjusting members arranged on the outside of the rotor nozzle. These allow a continuous or a gradual metering of the amount of liquid flowing through the bypass line, so that the operator has the possibility of adjusting the jet between a sharply focused, pure point jet and a highly diversified, largely homogeneous jet.
  • a particularly favorable solution for the adjustment of the metering valves is obtained if an adjusting ring is rotatably mounted on the housing concentrically to the axis of rotation of the rotor and has on its inside bearing surfaces for valve bodies of the metering valves protruding radially from the housing and elastically pressed against the bearing surface. and if the contact surfaces on rotation of the adjusting ring in the contact area against the valve body are at a different radial distance from the axis of rotation of the adjusting ring exhibit.
  • the bypass line can thus be opened and closed in a metered manner, so that the operator can control the nature of the jet essentially continuously between a point jet and an expanded jet with a circular cross section without additional tools.
  • a closable bypass branching upstream of the rotor from the flow path of the cleaning liquid can also be provided, which bypasses the rotor in such a way that the cleaning liquid flowing through it does not contribute to the rotary drive of the rotor.
  • the rotor in which the rotor is rotatably mounted on a hollow shaft which supplies the cleaning liquid to the inside of the rotor, it can be provided that a piece of pipe axially displaceably mounted in the housing is immersed in the hollow shaft, which in the fully inserted state relative to the hollow shaft is essentially sealed, but when pulling out of the hollow shaft forms a connection between the interior of the pipe section and the bypass.
  • a piece of pipe axially displaceably mounted in the housing is immersed in the hollow shaft, which in the fully inserted state relative to the hollow shaft is essentially sealed, but when pulling out of the hollow shaft forms a connection between the interior of the pipe section and the bypass.
  • the pipe section has lateral wall openings which are covered by the hollow shaft when the pipe section is fully inserted, but are released from the wall of the hollow shaft when the pipe section is pulled out of the hollow shaft, and if an annular channel surrounding the pipe section is one Forms part of the bypass.
  • the adjustment of the pipe section is particularly simplified if the pipe section is screwed into an internally threaded bore of the housing that runs coaxially to the axis of rotation of the rotor.
  • the ratio of the amount of liquid passed through the rotor to the amount of liquid passed by the rotor and thus the speed of rotation of the rotor which is set can be continuously adjusted simply by rotating the pipe section relative to the housing and by the associated axial displacement in the thread.
  • the rotor nozzle shown in Figure 1 comprises a cylindrical housing 1 which carries an internally threaded bore 2 on one side, while it is open on the opposite side.
  • the inner threaded bore 2 is followed by a bore with a smooth inner wall 4, which merges into a bearing bore 5 with a reduced inner diameter and finally opens into the cylindrical interior 6 of the housing 1, the inner diameter of which is substantially larger than the inner diameter of the bearing bore 5.
  • a hollow shaft 7 is inserted into the bearing bore 5, which is supported with an annular flange 8 on the step 9 between the inner wall 4 of the bore 2 and the bearing bore 5 and which projects into the interior 6 of the housing.
  • a rotor 10 is rotatably mounted, which has two arms 12 projecting radially from the hollow shaft 7 and reaching as far as the inner wall 11 of the interior 6.
  • the rotor 10 is secured on the hollow shaft 7 in the axial direction on the one hand by a step 13 on the outer circumference of the hollow shaft 7 and on the other hand by a screw 14 which is screwed into the free end of the hollow shaft 7 and thereby closes the end of the hollow shaft 7.
  • the hollow shaft 7 has at the height of the arms 12 of the rotor 10 wall openings 16 which connect the interior of the hollow shaft 7 with the interior 17 of the rotor 10, which again through holes 18 in the arms 12 with outlet openings 19 to the Ends of the arms 12 communicates.
  • the outlet openings point in opposite directions in the circumferential direction, so that liquid escaping through the outlet openings 19 rotates the rotor on the hollow shaft 7.
  • the liquid supply to the hollow shaft 7 takes place via a pipe piece 20 screwed into the internally threaded bore 2, which carries a coupling ring on the part emerging from the housing 1 for connection to a jet pipe of a high-pressure cleaning device (not shown in the drawing), while on the opposite side into the Hollow shaft 7 immersed.
  • the pipe section 20 is sealed by means of an annular seal 22 with respect to the smooth inner wall 4 of the bore 2, in addition the tubular section 20 also carries a further annular seal 23 in a conically narrowing transition region 24, which seals a complementary one when the tubular section 20 is fully inserted into the hollow shaft 7 Sealing surface 25 lies in the entry area into the hollow shaft 7.
  • a plurality of radial openings 26 are arranged in the wall of the pipe section, which are sealed off from the inner wall of the hollow shaft 7 when the pipe section 20 is fully inserted into the hollow shaft 7, as shown in FIG. 1.
  • the pipe section 20 can be rotated in the internal threaded bore 2 with respect to the housing 1 and thereby displaced in the axial direction until the interior of the pipe section 20 is connected via the openings 26 to the annular channel 27 formed by the bore 2 and surrounding the pipe section 20, such as this is shown in the embodiment of Figure 2.
  • This ring channel 27 is connected via a series of channels 28 directly to the interior 6 of the housing 1, so that part of the liquid supplied through the pipe section 20 is bypassed on the rotor 10 is led past.
  • This bypass is formed by the openings 26 in the pipe section 20, by the ring channel 27, by the channels 28 and by the interior 6 of the housing.
  • the liquid which bypasses the rotor is combined again with the liquid which has flowed through the interior of the rotor and reaches the interior 6 through the outlet openings 19.
  • a driver 29 which has a groove or opening 30 running radially from the center to the outside.
  • a driver pin 31 of a stilt 32 which carries a nozzle 33 with a spherical head, plunges into this groove.
  • This stilt 32 has lateral openings 34, which connect the interior 6 of the housing 1 to the nozzle opening 36 in the nozzle 33 via a central channel 35 in the stilt 32.
  • This stilt is supported with the spherical part of the nozzle 33 in a central bearing socket 37 which has a central opening 38 in alignment with the nozzle opening 36.
  • the bearing socket 37 is arranged in the end wall 39 of an adjusting sleeve 40, which plunges into the open end of the housing 1 in a sealed manner by means of an annular seal 41 and is mounted on the housing 1 so that it cannot move and can rotate freely in the axial direction.
  • the housing has an annular groove 42 on its inner wall and the adjusting sleeve 40 has an annular groove 43 aligned with the annular groove 42 on its outer wall, into which a clip 44 is inserted.
  • the adjusting sleeve 40 has an internal thread 45, into which a hood-shaped stop 46 is screwed, which engages in longitudinal grooves 48 on the inner wall of the interior 6 of the housing 1 by means of laterally projecting guide projections 47 and thereby the hood-shaped stop 46 relative to the housing 1 axially displaceable, but non-rotatably.
  • the hood-shaped stop 46 When the adjusting sleeve 40 is rotated relative to the housing 1, the hood-shaped stop 46 thus screws more or less deeply into the internal thread 45, that is to say the stop 46 can also be shifted between a fully screwed-in position (FIG. 1) into a position in which the rotor 10 is approximated. In this position, the hood-shaped stop 46 extends over the driver 29 of the rotor 10 (FIG. 2).
  • the stop 46 is provided with an inwardly projecting stop edge 49 which runs concentrically to the axis of rotation of the rotor and which abuts the outer wall of the stilt 32 and thus the inclination of the stilt 32 relative to the axis of rotation of the rotor limited.
  • the stop 46 shown in FIG. 1 in which it is completely screwed into the internal thread 45, a very extensive inclination is possible, whereas in the extreme case of the stop completely screwed out, an inclination of the stilt 32 is prevented at all, so the exit axis of the nozzle practically coincides with the axis of rotation of the rotor.
  • the hood-shaped stop 46 also forms a collecting space 50 for the liquid entering the interior 6.
  • This collecting space 50 is conically narrowed in the part facing the nozzle 33, so that the liquid is supplied on the one hand to the openings 34 in the stilt 32, but on the other hand to the central opening 51 which is surrounded by the stop edge 49 and through which the stilt 32 passes through.
  • the bearing socket 37 is provided concentrically surrounding a plurality of bores 52 which are parallel to the axis of rotation of the rotor and which open into radial bores 53 of the adjusting sleeve 40 leading from the outside inwards.
  • These radial bores 53 initially have an enlarged outer part 54 and then an inner part 55 with a reduced cross section, which opens into a central, funnel-shaped opening 56 in the adjusting sleeve 40, which adjoins the opening 38 of the bearing socket 37 connects.
  • the bores 53 enter the funnel-shaped opening 56 in the radial direction.
  • valve bodies 57 which are displaceable in the longitudinal direction of the bore are arranged, which are sealed off from the bore 53 by means of ring seals 58 and optionally close or release the bore 53 in the transition region between the outer part 54 and the inner part 55.
  • the valve bodies 57 are pressed radially outward by a coil spring 59 arranged in the outer part 54 of the bore 53 against a contact surface 60 on an adjusting ring 61, which in turn is rotatably mounted on an external thread 62 of the adjusting sleeve 40.
  • the contact surface 60 has different distances in the axial direction from the axis of rotation of the adjusting ring 61, so that when the adjusting ring 61 is rotated, the valve body 57 is pressed into the bore 53 to a different depth against the action of the helical spring 59, and the flow cross section of the bore 53 is more or less release less or close completely when fully inserted.
  • this reduces the exit velocity in the point jet, since the amount of liquid becomes smaller, on the other hand, the amount of liquid entering the point jet at the side tears open and mixes with the amount of liquid in the point jet to form a fanned out, voluminous jet with a circular cross-section and a lower impact velocity of the liquid particles .
  • This transition can be varied continuously by adjusting the metering valves.
  • the bypass line formed by the bores 52 and 53 is opened; in the exemplary embodiment in FIG. 2, however, the metering valves are shown closed.
  • the adjustment of the valve body is not over one made of the adjusting sleeve rotatable adjusting ring, but the valve bodies 57 are screwed into the outer part 54 of the bore 53 and can be rotated directly via knurled disks 63 and adjusted to different immersion depths.
  • a rotor nozzle is obtained which initially gives the possibility of steplessly adjusting the angle of the point jet emerging from the nozzle between 0 and a maximum value, for example 10 °. It is also possible to continuously adjust the speed of the jet by not directing part of the liquid through the rotor, but past the rotor. Finally, the nature of the jet itself can also be changed by dividing the liquid flow through the nozzle 33 and adding a quantity of liquid transversely to the point jet. Overall, you get a very variable rotor nozzle, which is robust in construction and allows easy operation of the various adjustment options.
