  • the invention is based on the object of specifying a cleaning device which is improved over the prior art.
  • a cleaning device for cleaning with a cleaning liquid in particular for cleaning, in particular internal cleaning, of hollow bodies, comprises a tubular section, at least one cleaning head rotatable about a first axis of rotation on a cleaning head end region of the tubular section, a spray arm, which rotates about an at least substantially perpendicular to the first Axis of rotation aligned second axis of rotation is rotatably arranged on the cleaning head, a drive device for driving the cleaning head and the spray arm a driving end region of the tubular section opposite to the cleaning head end region; and a cleaning liquid line for the cleaning liquid, which runs through the tubular section.
  • the cleaning liquid line also runs through the cleaning head and the spray arm and ends in at least one outlet opening, the cleaning liquid line being designed to be liquid-tight with respect to the interior of the cleaning device. All cleaning device components are arranged outside the cleaning liquid line.
  • the cleaning liquid line is thus designed as a line that is completely closed with respect to the cleaning device interior, for example tubular, hose-shaped or channel-shaped, for example as a cleaning liquid pipe, cleaning liquid hose or cleaning liquid channel. It thus has its own line wall that is completely closed within the cleaning device.
  • This line wall encloses a line interior space which is provided exclusively for flow, in particular for flow of the cleaning liquid.
  • No other cleaning device component is arranged in this line interior space enclosed by the line wall, in particular no drive component, in particular no drive shaft, no transmission component, no transmission, no bearing component and no bearing, i. H. in particular no component required for rotating the cleaning head and/or the spray arm and in particular not movable for this purpose.
  • the solution according to the invention achieves, at least essentially, a constant flow cross section of the cleaning liquid line, as a result of which pressure losses are reduced.
  • turbulence of the cleaning liquid and a resulting flow disturbance caused by cleaning device components arranged in the cleaning liquid line and in particular moving therein are avoided, since the solution according to the invention does not have such cleaning device components in the cleaning liquid line.
  • the cleaning liquid line runs completely through the tubular section, i. H. from the drive end area to the cleaning head end area. It thus enters the tubular section in particular at the drive end area in the axial direction of the latter and exits from the tubular section at the cleaning head end area in the axial direction.
  • a lateral, d. H. radially to the tubular section, running entry of the cleaning liquid line in the tubular section and an associated crossing in the tubular section of rotating components or entry into these rotating components, for example associated with complex sealing measures avoided.
  • the tubular section, the cleaning head and the at least one spray arm, with the exception of the at least one outlet opening are sealed against the external environment in a liquid-tight manner.
  • the interior of the cleaning device is sealed in a liquid-tight manner in relation to the external environment. Due to the encapsulated design of the cleaning liquid line described above, the penetration of the cleaning liquid and, for example, from the to cleaning hollow body removed dirt avoided in the cleaning device interior.
  • the liquid-tight closed design of the tubular section, the cleaning head and the at least one spray arm with the exception of the at least one outlet opening in relation to the external environment also prevents the cleaning liquid sprayed by means of the cleaning device and, for example, the dirt removed from the hollow body to be cleaned from penetrating from the outside the external environment of the cleaning device, into the cleaning device interior is avoided.
  • This is achieved in particular in that the interior of the cleaning device is closed in the manner described to the outside, ie in a liquid-tight manner in relation to the external environment, and is therefore embodied in an encapsulated manner.
  • All cleaning device components required for the rotational movement of the cleaning head and the at least one spray arm are therefore expediently inside this liquid-tight seal of the tubular section, the cleaning head and the at least one with respect to the external environment Spray arm and thus in particular within the liquid-tightly sealed relative to the outside environment and thus advantageously encapsulated cleaning device interior are arranged.
  • the cleaning device comprises two drive arrangements that are independent of one another, in particular completely independent of one another, ie a drive arrangement for driving the cleaning head and a further drive arrangement for driving the spray arm.
  • the two drive assemblies each include one Drive unit, in particular a drive motor.
  • the rotational movements of the cleaning head and spray arm can be carried out independently of one another, in particular the rotational speeds of the cleaning head and spray arm can be set independently of one another, in particular controlled and/or regulated independently of one another.
  • the rotational movements of the cleaning head and at least one spray arm can be carried out independently of one another in such a way that they do not influence one another.
  • the respective drive unit is designed in particular as an electric, pneumatic and/or hydraulic drive unit.
  • the respective drive unit designed as a drive motor is designed as an electric motor.
  • the respective drive unit designed as a drive motor can be designed as a pneumatic motor or hydraulic motor, for example.
  • the respective drive unit can be designed, for example, as a turbine, in particular as a hydraulically operated turbine and thus as a hydraulic drive unit designed as a turbine.
  • the two drive units can be of the same or different design.
  • the cleaning device thus enables rotational movements that can be controlled and/or regulated independently of one another about two axes of rotation, in particular about the vertical first axis of rotation and the horizontal second axis of rotation.
  • rotational movement of the cleaning head there is a forced coupling between the rotational movement of the cleaning head and the rotational movement of the spray arm. This results in fixed cleaning paths, which are described by a jet of the cleaning liquid sprayed by the spray arm.
  • the hollow body to be cleaned has areas that have to be cleaned more intensively, for example areas in which there are product residues increased deposits, and/or agitators, nozzles, manholes and/or other openings in the area of which a surface shape makes cleaning difficult, and/or areas where sensors are arranged.
  • the cleaning head and the spray arm can be rotated in such a way that the jet of cleaning liquid sprayed by the spray arm is directed more strongly at these areas, because the jet of cleaning liquid can be directed specifically at any point on a surface of the hollow body become.
  • All areas to be cleaned can thus be sprayed with the cleaning liquid as required, in contrast to the cleaning devices according to the prior art, which spray all areas evenly.
  • any desired cleaning path can be designed due to the separate drive of the cleaning head and spray arm, i. H.
  • Cleaning lanes and cleaning processes can be freely parameterized. This is not possible using gear solutions, which force the rotation of the cleaning head and spray arm to be coupled.

  • the drive arrangements and advantageously all of the components driven by them are advantageously independent of one another in such a way that they do not influence one another. In particular, their movements are decoupled from one another. Movements of one of the drive arrangements and the movable components assigned to it therefore have no influence on movements of the respective other drive arrangement and the components assigned to it.
  • the tubular section includes an outer hollow shaft, which is coupled to the cleaning head and, via a gear, to the drive unit, in particular the drive motor, for driving the cleaning head.
  • an inner hollow shaft is arranged in the outer hollow shaft, which is coupled to the spray arm via a gear on the spray arm and to the drive unit, in particular the drive motor, for driving the spray arm via a gear on the drive motor.
  • the cleaning liquid line therefore advantageously runs through the inner hollow shaft.
  • the cleaning liquid line has its own line wall, i. H. it runs in the form of a tube or hose inside the hollow inner shaft, so that the cleaning liquid does not come into contact with the hollow inner shaft. This prevents deposits on the inner hollow shaft and prevents the cleaning liquid from being influenced by the rotation of the inner hollow shaft.
  • a sensor for determining a rotational position of the cleaning head and/or a sensor for determining a rotational position of the spray arm is/are provided. This enables the jet of sprayed cleaning liquid to be precisely aligned onto an inner surface area of the hollow body that is to be cleaned in each case.
  • the tubular section is designed to be telescopic, in particular as a telescopic tube arrangement made up of a plurality of tube elements which can be displaced axially relative to one another and advantageously engage in one another in a form-fitting manner.
  • This telescoping is also possible independently of one or more features described above.
  • both the inner hollow shaft and the outer hollow shaft are designed to be telescopic.
  • a flexible shaft or a telescopic bellows can be provided for the respective torque transmission.
  • This telescoping allows, advantageously in addition to the two independent rotational movements of the cleaning head and spray arm about two axes, a translational movement along one axis, more precisely along the first axis of rotation, i. H. a translational movement of the cleaning head with the spray arm axially to the tubular section and thereby a lowering and raising of the cleaning head with the spray arm in the hollow body to be cleaned.
  • This translational movement, i. H. the telescoping can, for example, take place manually and/or by means of a telescopic drive, for example comprising a further drive motor, and thus in particular automatically.
  • the telescopic drive can be used to telescope the tubular section, i. H. for retracting and extending, for example a cable, a chain, a belt or a spindle.
  • telescoping for example, installations in the hollow body to be cleaned, for example an agitator, can also be cleaned from below in a targeted manner by lowering the cleaning head with the spray arm in the hollow body by extending the telescoping tubular section.
  • an immersion depth of the cleaning head with the spray arm in the hollow body to be cleaned can be extended, for example, at will, at least within the scope of the maximum telescopic length of the tubular section.

  • This line wall 29 is at a distance from an inside of the inner hollow shaft 15 in order to enable the inner hollow shaft 15 to rotate without rubbing against the cleaning liquid line 24, because the section of the cleaning liquid line 24 running through the tubular section 3 does not rotate, neither with the outer hollow shaft 14 nor with the Hollow inner shaft 15.
  • the spacing of hollow inner shaft 15 and cleaning liquid line 24 and the resulting rotation of hollow inner shaft 15 relative to stationary cleaning liquid line 24 without damaging it is achieved by a bearing 31 between hollow inner shaft 15 and line wall 29.
