Definitions

  • the invention relates to a nozzle head with a rotatable about an axis, drivable, equipped with nozzles nozzle holder, and a stationary, a pressurized water connection housing, in which a connected to the nozzle holder, provided with a continuous central channel for the pressurized water supply to the nozzle holder Hollow shaft is rotatably mounted and in the central channel extends with an annular flange supporting in the pressurized water connection sleeve.
  • a nozzle head of this type is known (DE 38 12 132 C2), in which the drive is effected by the recoil of the pressurized water emerging from the nozzles and in which the rotational movement of the nozzle carrier is braked by means of a brake.
  • the spray direction of the nozzles is specified for this nozzle head.
  • the insertion sleeve extending from the pressurized water connection and extending into the central channel of the hollow shaft is received by a bore of the hollow shaft which is enlarged in diameter compared to the central channel.
  • a labyrinth gap seal with annular grooves widening on one side and provided in the insertion sleeve is arranged between the insertion sleeve and the hollow shaft.
  • the invention has for its object to design a nozzle head of the type mentioned so that the wearing parts in the region of the hollow shaft can be replaced in a simple manner and the nozzle holder has nozzles, the spray direction can be chosen arbitrarily.
  • the insertion sleeve consists of two sleeves 11, 16 which surround one another in the central channel of the hollow shaft over a partial length or over the entire length, with a labyrinth gap seal being arranged in the overlap region between the sleeves and the hollow shaft is driven by a motor.
  • the motor drive of the nozzle carrier eliminates the need for a braking device, and it is possible to set the spray direction of the nozzles parallel to the axis of rotation or in or against the direction of rotation of the nozzle carrier.
  • the two sleeves enclosing with surface closure can be designed as insert sleeves, the sleeves being inserted from the ends of the hollow shaft and thus being able to be replaced in a simple manner if these sleeves have to be replaced by new sleeves due to the wear that has occurred during operation.
  • An electric motor, a hydraulic or pneumatic motor can be used as the drive motor. It is also conceivable to use a motor whose drive means consists of the leakage water, which can be taken up by a chamber and drawn off via channels.
  • FIG. 1 An embodiment of a nozzle head according to the invention is shown in the drawing in longitudinal section.
  • the nozzle head 1 has a housing 2 which is delimited at one end by an end plate 3 and at the other end by an end plate 4.
  • the end plate 3 is in one piece with the housing jacket.
  • the other end sheath is supported on a spring ring 4 and is fixed in the housing by a Seeger ring 5.
  • Rolling bearings 6 and 7 are arranged in the end disks, in which a hollow shaft 8 is rotatably mounted, which has a central, continuous channel 9.
  • the inner diameter of this central channel 9 is about the entire channel length remains the same.
  • the end plate 3 is equipped with a pressurized water connection 10. Through this pressurized water connection, an insertion sleeve 11 is inserted into the central channel 9, which is provided at its end with an annular flange 12 which is supported on a stop surface 13 of the end plate 3.
  • the insertion sleeve 11 is composed of a part 14 with an outside diameter that corresponds to the inside diameter of the channel 9 and a part 15 whose outside diameter is twice the wall thickness of the second insertion sleeve 16 than the outside diameter of the part 14.
  • a second insertion sleeve surrounds part 15 of the first insertion sleeve flush with the surface, ring grooves of a labyrinth gap seal being arranged in part 15.
  • the second insertion sleeve 16 is equipped with an end-side ring flange 17, which is supported on the front end of the hollow shaft, which faces a nozzle carrier 18. On this nozzle carrier nozzles 19 are fixed, to which pressurized water is supplied through the central channel 9 and through bores 20 in the nozzle carrier.
  • the nozzle carrier 18 is fastened to the hollow shaft 8 by a union nut 21.
  • the hollow shaft extends through a rotor 21 of an electric motor, the two parts being connected to one another.
  • the rotor is enclosed by a stator 20, which is fixed in the housing 2.
  • the insertion sleeve 11 is arranged in a stationary manner.
  • the insertion sleeve 16 rotates with the hollow shaft 8 and with the nozzle carrier 18.
  • the sleeve 11 can be removed through the pressurized water connection 10 and the insertion sleeve 16 can be pulled out of the channel 9 after the nozzle holder 18 has been removed.
  • a chamber 23, which is arranged in the end plate 3, is provided for receiving the leakage water which occurs during operation.
  • the leakage water can be drawn off through the channels 24.
  • the nozzle head With the arrangement of the electric motor in the housing 2 and with the attachment of the nozzle carrier 18 to the end of the hollow shaft 8 protruding from the housing, the nozzle head forms a compact structural unit.
