Definitions
- the invention relates to a cleaning device for cleaning a container, in particular an orbital cleaner, and a method for driving a cleaning device.
- Cleaning devices of the type mentioned are generally known. They are used, for example, in the food and beverage industry for hygienic and, in particular, sterile cleaning of containers.
- So-called orbital cleaners work on the basis of two rotating axes, a vertical and a horizontal axis, around which a round jet nozzle rotates in such a way that a highly concentrated jet of water or cleaning agent with high impact ensures intensive cleaning of the surfaces of tanks and containers.
- Such cleaning devices are mostly driven by the inflowing fluid, in particular cleaning agent itself.
- a rotor is arranged in the flow path of the fluid flowing into the cleaning device in such a way that the rotor is driven as a function of the flow velocity.
- the cleaning device and in particular a nozzle head for such a cleaning device, is driven around a first axis.
- the invention solves the above-mentioned object by a cleaning device according to claim 1.
- the invention proposes a cleaning device of the type mentioned at the outset, comprising: a housing with a fluid inlet for admitting a fluid, in particular cleaning agent, a rotor which rotates relative to the housing is drivable about a first axis of rotation, a nozzle head with a fluid outlet for dispensing the fluid, in particular cleaning agent, wherein the nozzle head is mounted on the rotor rotatably about a second axis of rotation, a flow channel for fluid-conducting connection of the fluid inlet and the fluid outlet, a passage which fluid-conducting is set up to conduct part of the flowing fluid to the rotor in order to apply a drive torque and to drive the rotor rotationally, and a drive unit which is coupled to the rotor on the drive side and to the nozzle head on the driven side and is set up for this purpose is to transmit the drive torque of the rotor to the nozzle head.
- the invention includes the knowledge that in the cleaning devices of the type mentioned at the outset, the arrangement of the rotor in the flow path restricts the design variety in such cleaners.
- the invention further includes the knowledge that the arrangement of the rotor in the flow path causes turbulent flows or flow disturbances, so that the drive of the nozzle head is impaired.
- the invention includes the knowledge that, as a result of the drive of the nozzle head, depending on the flow speed, these turbulences and flow disturbances lead to a discontinuity and impairment of the control of the nozzle head.
- One advantage of the invention lies in the fact that a passage which is fluidly configured to conduct part of the flowing fluid to the rotor enables reliable drive of the rotor and at the same time impairs or creates turbulence in the flowing fluid between the Fluid inlet and the fluid outlet avoids. Furthermore, such a passage advantageously enables a pressure-controlled drive torque to be generated, which is therefore no longer solely due to the Flow rate of the flowing fluid is controlled. The design variety of such an advantageous cleaning device is thus increased and the controllability of the drive as a function of the pressure is made possible.
- the rotor or the housing has at least one rolling element, the housing or the rotor having at least one rolling surface arranged coaxially to the rotor, and the part of the flowing fluid being guided to the rotor in such a way that the rolling element passes through the fluid is moved along the rolling surface.
- a drive torque is thus applied to the rotor by driving a rolling element along a rolling surface arranged coaxially to the rotor.
- Such a rolling element is preferably coupled to the rotor in such a way that the rolling element is moved along the rolling surface and thus around the first axis of rotation, so that the rotor rotates around the first axis of rotation relative to the housing.
- the rolling surface is preferably formed by an, in particular rotationally symmetrical, inner wall of the housing that is formed around the first axis of rotation and extends in the axial direction.
- the rolling surface is formed by an, in particular rotationally symmetrical, outer wall of the rotor that is formed around the first axis of rotation.
- the inner wall extends at least along part of the rolling element in the axial direction, so that the latter is moved in a guided manner along the inner wall which forms the rolling surface.
- the at least one rolling element can preferably be arranged radially inside the rolling surface.
- the distance between the rolling surface and the axis of rotation is not constant, so that the rolling surface has at least one first section in which the distance decreases and has at least one second section in which the distance increases.
- a movement of the rolling element in the radial direction is also generated, which is dependent on the distance between the rolling surface and the axis of rotation.
- a movement of the rolling element in the radial direction also leads to a movement of the rolling element in the circumferential direction along the rolling surface.
- the rotor preferably has a plurality of rolling elements and the rolling surface has a plurality of first sections in which the distance decreases and a plurality of second sections in which the distance increases, a first section in each case being arranged adjacent to a second section.
- a movement of the roller body radially outwards thus simultaneously leads to a movement in the circumferential direction.
- an adjacent rolling element can be driven radially outward by the flowing fluid so that it is also moved in a defined area in the circumferential direction.
- the successive movement in the circumferential direction of the plurality of rolling elements causes the rotor to rotate about the first axis of rotation.
- the passage is preferably connected in a fluid-conducting manner to a pressure space for pressurized fluid that is at least partially formed by the flow channel. In this way, fluid under pressure can get into the passage particularly easily.
- the passage can be connected in a fluid-conducting manner to a pressure space for pressurized fluid, which is at least partially formed by an interior of the rotor.
- the drive unit comprises: a drive shaft for driving the nozzle head, which is arranged coaxially to the second axis of rotation and is coupled to the rotor in such a way that the drive shaft with the rotor is driven about the first axis of rotation, and one relative to the first and second axis of rotation stationary receptacle, wherein the drive shaft is in engagement with the stationary receptacle in such a way that the drive torque of the rotor is transmitted to the drive shaft and the drive shaft rotates about the second axis.
- the stationary receptacle preferably has a stationary bevel gear, which is arranged coaxially to the first axis of rotation and is tapered on the rotor side, and the drive shaft has a bevel drive gear for torque-transmitting coupling with the stationary bevel gear, which is arranged coaxially to the second axis of rotation and in the direction of the first axis of rotation is tapered.
- the drive unit is thus designed in the manner of a bevel gear, which comprises the first axis of rotation and a second axis of rotation which is arranged at an angle to the first axis of rotation and which have a common point of intersection. The power is transmitted through the first and the drive bevel gear.
- Such a bevel gear preferably has an external toothing, the teeth of the drive bevel gear rolling or sliding along the teeth of the stationary bevel gear.
- the sliding or rolling is generated by the relative movement of the drive bevel gear relative to the stationary bevel gear.
- the stationary bevel gear is preferably a ring gear and the drive bevel gear is preferably a pinion.
- the bevel gears mesh with one another in such a way that both a relative movement of the drive bevel gear around the first axis of rotation in a first direction of rotation and in a second direction of rotation cause the drive torque of the rotor to be transmitted around the first axis of rotation to the drive shaft.
- the flow channel has a first cross-sectional area and the passage has a second cross-sectional area, the second cross-sectional area being smaller than the first cross-sectional area.
- the flow rate of the fluid in the passage can thus be increased by the second cross-sectional area, which is smaller than the first cross-sectional area.
- the first cross-sectional area of the flow channel can be smaller than the second cross-sectional area of the passage, so that the flow velocity of the fluid can be high and a comparatively slow rotation of the nozzle head about the first axis and the second axis is generated.
- the housing preferably has a cylindrical section which is arranged coaxially to the first axis of rotation and which forms a section of the flow channel, and wherein the stationary bevel gear is formed at an end of the cylindrical section on the rotor side.
- the stationary receptacle is thus formed by the cylindrical section which has the stationary bevel gear on the rotor side.
- the design of the The housing is thus made more compact, since a part of the flow channel, namely the part of the flow channel which has the fluid inlet and can be coupled to a supply line, forms the stationary receptacle.
- This part of the flow channel is conventionally designed to be stationary, since a reliable fluid-conducting coupling to the supply line must be ensured.
- the rotor has a cage for guiding the rolling element in the radial direction, which is arranged coaxially to the first axis of rotation and is set up to rotate with the rolling element about the first axis of rotation.
- the majority of the rolling elements are thus coupled to one another and guided in the radial direction.
- a movement of one rolling element in each case in the circumferential direction thus requires a movement in the circumferential direction of all of the rolling elements which are guided through the cage.
- the movement of one rolling element in each case radially outward through a part of the flowing fluid thus equally causes a relative movement in the circumferential direction of all rolling elements.
- the cage is preferably at least partially received on the housing and the rolling element is guided through the cage in such a way that the rolling element can be moved in the radial direction between the cage and the rolling surface. This ensures a guided movement of the rolling element in the radial direction.
- the cage also preferably has a plurality of receptacles which are arranged along an outer circumference of the cage and are designed to at least partially receive a rolling element and to guide it in the radial direction.
- a rolling element e.g., a rolling element which guide the rolling elements in the radial direction
- the plurality of rolling elements can be received by the cage in such a way that they can be moved within the receptacles in the radial direction between the rolling surface and an inner contact surface of the respective receptacle.
- the passage is preferably connected in a fluid-conducting manner to at least one receptacle, so that part of the flowing fluid is introduced between the rolling element and an inner contact surface of the receptacle and strikes the rolling element in such a way that it is pressed radially outward.
- the rolling elements are preferably designed to be cylindrical and the receptacle is designed to be partially cylindrical, corresponding to the rolling elements. Such a cylindrical design prevents the rolling element from tilting within the receptacle.
- the receptacles preferably each have an opening facing away from the housing, which can be connected to the passage in a fluid-conducting manner. Thus, part of the flowing fluid can be introduced through the opening between the rolling element and an inner contact surface of the receptacle in such a way that the rolling element is pressed radially outward.
- the rotor further comprises a cover element, which is designed to close the openings, and wherein the cover element has a plurality of channels which can be connected to the passage in a fluid-conducting manner.
- At least one discharge channel is formed in such a cover element, from which the fluid located in the receptacle can flow after the respective rolling element has been moved radially outward.
- the invention also relates to a method for driving a cleaning device, in particular a cleaning device of the type described above.
- the invention achieves the object described above in a second aspect through the subject matter of claim 18.
