Description

TECHNICAL AREA

The invention relates to a container cleaning device, which is insertable into an opening of a container and a housing body having a connected to a supply line for cleaning liquid, with respect to the container rotatably disposed connection housing, and a respect to the latter about a first axis of rotation rotatable nozzle head housing, with at least one the nozzle head (s) in use, a (1 which are arranged inside, on or outside the container cleaning device and possibly also outside the container and driven by external energy.

STATE OF THE ART

A container cleaning device of the generic type, in which the drive means are arranged outside the container cleaning device and driven by external energy is in the DE 100 24 950 C1 described.

The container cleaning device according to document EP 1 062 049 B1 has in the upper region of the rotationally fixed, stationary housing part in addition to a spray nozzle. The injection direction of this additional spray nozzle, based on the presentation position of the device, aligned downward in the direction of the orbital unwinding nozzle assembly to effect the required self-cleaning here. The cleaning of the container itself is not improved or intensified by this additional spray nozzle.

The mutual sealing of the relatively movable parts of the known device according to EP 1 062 049 B1 is largely done in such a way that a leakage of cleaning liquid from the interior of the container cleaning device is prevented in its environment by suitable sealing elements. In this case, the joints of the relatively movable parts represent problem-critical problem areas that can be insufficiently cleaned by the aforementioned spray nozzle.

A both inside and outside self-cleaning designed container cleaning device is from the EP 0 560 778 B1 known. There, a spray device which revolves around the second axis of rotation and which is in the form of a shield which covers part of the circumferential ring gap present on the nozzle head and deflects the liquid which flows out against the shield so as to deflect the outer surfaces of the nozzle Housing of the container cleaning device cleans. This also the self-cleaning of the device serving spray nozzle can not improve the cleaning of the container itself also.

As between the relatively movable parts of the container cleaning device according to EP 0 560 778 B1 relatively large-sized, liquid-permeable peripheral annular gaps are arranged, are diverted from the passing through the device stream of cleaning liquid two relatively large partial flows through this peripheral annular gaps, which are then no longer available to the nozzles on the nozzle head for their actual task, namely the cleaning of the container. The partial flow leaving the entire circumference of the respective circumferential ring gap is difficult to limit to the necessary extent, and on the other hand, in its respective size, it is substantially dependent on the prevailing pressure conditions in the interior of the container cleaning device, which may be subject to temporal variations.

A rotating with the nozzle head spray device according to EP 0 560 778 B1 Which is in the form of a shield, which covers part of the present on the nozzle head peripheral annular gap and the liquid against the Blade deflects so distracts that it cleans the outer surfaces of the housing of the container cleaning device, is problematic in terms of their supply of cleaning liquid in that this supply in turn depends in turn on the pressure and flow conditions in the associated circumferential annular gap.

In the two aforementioned container cleaning devices ( EP 1 062 049 B1 ; EP 0 560 778 B1 ) arranged on the respective nozzle head nozzles perform a superimposed spatial rotational movement about two axes of rotation, whereby the spray jets emerging from these nozzles develop a particularly intensive mechanical cleaning effect by their orbital kinematics on the inner surface of the container to be cleaned. Depending on the ratio of the realized about the two axes of rotation speeds results on the inner surface of the container a typical, repeatedly generated at certain intervals spray pattern. It has been shown in this regard that the intensive mechanical cleaning effect of emerging from the orbital unwinding spray jets solve contamination on the container surface well, but often the amount of detergent dispensed thereby is insufficient to wash the loosened contaminants quickly from the container wall and the outlet of the container supply. In order to ensure a complete transport of dissolved contaminants in the outlet of the container, therefore, often the container cleaning device remains in operation longer than would be necessary in view of the up and to be removed soiling in itself.

In addition, container cleaning devices are known in which a nozzle head provided with at least one nozzle rotates about a single axis of rotation, while the inner wall of the container at all times in the same places wraps around. In this case, the rotational movement of the nozzle head about the respective axis of rotation can be generated by drive means which are arranged outside the container cleaning device and also outside the container and driven by external energy (eg electric motor) ( DE 1 869 413 U ). In the DE 26 45 401 C2 is a container cleaning device with the above kinematic Characteristics described, the drive means are arranged outside the container and driven by the flow energy of the container cleaning device inflow inlet stream of the cleaning liquid.

Finally, out of the DE 102 08 237 C1 a container cleaning device with the kinematic characteristics in question, in which the drive means for generating the rotational movement of the nozzle head are arranged entirely within the container cleaning device and driven by the flow energy of the container cleaning device inflow inlet stream of the cleaning liquid.

These three exemplary container cleaning devices ( FIGS. DE 1 869 413 U ; DE 26 45 401 C2 ; DE 102 08 237 C1 Though) bring sufficient amounts of cleaning liquid to the inner wall of the container, the cleaning effect of nozzles, which revolve around a single axis of rotation and meet their spray jets on getting the same points of the tank is facing an effective and economical cleaning of the entire container, however, usually unsatisfactory.

It is an object of the present invention to improve the container cleaning device of the generic type such that it additionally unfolds a particularly intensive, all container areas detected in a shorter time cleaning effect, the container cleaning device is spatially extremely compact and inside and outside has optimal self-cleaning properties.

SUMMARY OF THE INVENTION

This object is achieved by a container cleaning device having the features of claim 1. Advantageous embodiments of the proposed container cleaning device are the subject of the dependent claims.

The crucial inventive idea of solution is that at least one additional nozzle is arranged on the nozzle head housing, which rotates about the first axis of rotation, which exclusively serves to clean the container. This additional nozzle differs decisively from known related solutions (eg EP 1 062 049 B1 ), in which the auxiliary nozzle is arranged stationary and only the self-cleaning (external cleaning) takes over the container cleaning device.

Since the additional nozzle according to the invention rotates only about the first axis of rotation and thereby delivers a second partial flow to the inner lateral surface of the container, which feeds from the inflow stream of the cleaning liquid flowing to the container cleaning device, this lateral surface is covered with cleaning liquid in shorter time intervals than with the cleaning liquid alone is the case around the two axes of rotation orbitally moving nozzles. The so-called surge cleaning applied alone about a rotation axis runs as a liquid film down the jacket surface of the container and thus contributes particularly effectively to a forced cleaning and to the accelerated discharge of dissolved soiling.

The respective drive means driven by external energy can thereby within ( DE 102 08 237 C1 ), be arranged on or outside of the container cleaning device, wherein in the latter embodiment, an arrangement is provided outside the container ( DE 1 869 413 U ; DE 26 45 401 C2 ).

The branch of the second partial flow find a particularly advantageous and simple design expression of the first kind, if, as provided, the second partial flow is supplied via at least one branch channel in the wall of the terminal housing an annular space which surrounds the terminal housing on the outside, which limits its relative to the environment via a formed on the nozzle head housing, rotatable on the connection housing undergoes mounted housing shaft and opens into the arranged in the housing shaft additional nozzle. The expression of the first type is particularly recommended when the applied around a rotation axis so-called surge cleaning by the addition of the invention nozzle desired or necessary from the outset and in addition to orbital cleaning through the nozzles on the nozzle head is provided.

A related embodiment of the invention of the second kind provides that the second partial flow is supplied via at least one branch channel in the wall of the terminal housing to an annular space which surrounds the connection housing on the outside, learns its limitation to the environment via a first or a second nozzle housing and in arranged in the nozzle housing auxiliary nozzle opens, wherein the nozzle housing is rotatably mounted on the connector housing and is in a positive driving connection with the nozzle head housing. The expression of the second kind is particularly recommended when the so-called surge cleaning is optionally desired by the additional nozzle according to the invention or during the operation of the container cleaning proves to be necessary, so that a simple retrofitting of the additional nozzle is ensured.

In the embodiment of the first or second type described above, the pressure and flow conditions of the first partial flow in the region of the nozzles on the nozzle head are not appreciably affected, since in this respect the location of the branch of the second partial flow and its position play only a minor role to the drive means.

The above-described embodiment of the first or second type then largely remains without influence on the pressure and flow conditions in the region of the first partial flow to the nozzles on the nozzle head, when the second partial flow is diverted completely in front of the arranged within the container cleaning device drive means. This configuration represents the most advantageous and preferred solution within the scope of the invention.

An advantageous embodiment of the container cleaning device according to the invention provides in the respective combination with the expression of the first or second type that the nozzle head housing additionally has at least one additional nozzle, wherein usually a maximum of two of these additional nozzles are provided. In this case, according to a further proposal, the respective additional nozzle is arranged at one of the possible points of the nozzle head housing, which have an unobstructed access to the interior of the nozzle head housing, based on its axial extent region along the first axis of rotation. Possible areas here are the jacket area of the nozzle head housing and / or preferably the transition area of the nozzle head housing between its jacket area and its frontal boundary area.

In this case, the orientation of the respective additional nozzle can take place in such a way as is furthermore provided that the line of action of its axis of symmetry intersects the first axis of rotation. However, the line of action of the axis of symmetry may also have a radial distance from the first axis of rotation. It is crucial in the arrangement and orientation of the additional nozzles that they bring their cleaning liquid in each case zoom in on the lateral surface of the container.

The additional nozzles are formed according to a further proposal in an advantageous manner as flat jet nozzles, which generate a fan-like flat jet, wherein in a preferred embodiment, the extension surface of the flat jet is substantially parallel to the first axis of rotation.

The design and arrangement of the additional nozzle is particularly simple, if this, as is also proposed, is formed by the wall of the nozzle head housing itself. For a related embodiment, namely an additional nozzle of the integrated form, the bulbous ausgestalte second nozzle housing is particularly suitable. Another relevant embodiment, namely an integrated additional nozzle, can be particularly simple in the transition region of the nozzle head housing between the jacket region and the front side Boundary surface are arranged, since there are particularly favorable geometric conditions.

Another proposal provides to form the additional nozzle as an independent component (independent additional nozzle) and this material fit, for example by welding, to be fixed in the corresponding drilled nozzle head housing. Furthermore, it is provided in this regard to arrange the additional nozzle in the form of the independent component form-fitting and / or non-positively in the nozzle head housing. Here, for example, a screwing or pressing in called. Solutions relating to this are then preferable to the cohesive fastening or the formation through the wall of the nozzle head housing itself, if cleaning operations can only be optimized during operation of the container cleaning device and, if necessary, a multiple replacement of different auxiliary nozzles is necessary.

A spatially extremely compact designed container cleaning device is present when it has in known manner a driven by the external energy planetary gear in conjunction with a bevel gear, which generate the rotational movement about the respective axis of rotation.

Will, as each provide a further proposal, arranged in the container cleaning device, the planetary gear in the area of the space, which is bounded by the two bevel gears of the bevel gear with their respective outer diameter and in the direction of their respective axes of rotation and bounded by a common spatial intersection of these Forms rooms, then results in the most conceivable compact spatial form of the subject container cleaning device, since the minimally possible axial extent of the container cleaning device is achieved by this fully integrated arrangement. None of the previously known in this respect container cleaning devices, it has been possible to completely integrate the entire planetary gear in the above-defined range within the bevel gear.

If, as provided in each case an advantageous embodiment, the first ring gear, seen in the direction of the first axis of rotation, a distance away from the first bevel gear and provided in the connecting region between the first bevel gear and the first ring gear a plurality of distributed over the circumference arranged first passage openings are, then already a large part of the container cleaning device passing through cleaning fluid, seen in the flow direction, are derived behind the first bevel gear in the nozzle head, without first having to flow through the planetary gear at least partially, as in the container cleaning device according to EP 0 560 778 B1 the case is. In the container cleaning device according to EP 1 062 049 B1 the planetary gear must be completely flowed through by the entire detergent flow, so there is the greatest possible flow resistance here. The inventive arrangement of the planetary gear, the internal flow losses of the cleaning liquid are reduced when passing through the container cleaning device, the partial flow of cleaning liquid, which still flows through the planetary gear, a sufficient cleaning thereof ensures.

The first ring gear, the first bevel gear and a fastening shaft on the latter side facing away from the ring gear expediently form an integral unit, as is provided in each case by a further proposal which is positively and / or non-positively connected, preferably screwed, to the connection housing , Such a one-piece unit can be produced for example as a casting or as a combined turned and milled part and it simplifies in this embodiment, the structure and the assembly of the container cleaning device substantially.

An economical handling of cleaning liquid for the purpose of self-cleaning of the two circumferential annular gaps is achieved without questioning the quality of this self-cleaning if, as a further embodiment of the container cleaning device according to the invention suggests, these circumferential annular gaps in each case in their permeability to cleaning fluid that Dimension is limited, which requires a sliding bearing paired, relatively rotatable mutually arranged parts of the container cleaning device or permits. For this purpose, it is provided that in the course of a first circumferential annular gap between the connection housing and the nozzle head housing and a second circumferential annular gap between the nozzle head housing and the nozzle head, in each case before exit of these circumferential annular gaps in the environment of the container cleaning device, a respective sliding ring is arranged, which is a first sliding bearing for the forms two housing with respect to their common first axis of rotation and a second sliding bearing for the parts with respect to their common second axis of rotation.

The sliding ring of a sliding bearing is known to form with the adjacent parts necessary bearing gaps, so that a sliding movement to form a liquid film (in this case, it is cleaning agent) is possible. The amount of this necessarily passing through the sliding bearing cleaning fluid is limited by the relatively narrow bearing gaps; however, it is sufficient to subject this critical area to self-cleaning. As a result of this measure, an unnecessarily large diversion of partial flows of cleaning liquid via the peripheral annular gaps is avoided, without their self-cleaning being called into question.

The cleaning of the circumferential annular gaps in the region between the respective slide bearing and the environment of the container cleaning device is ensured according to another proposal by the rotating with the nozzle head spray device. The latter is designed as a nozzle which is completely formed in the nozzle head. The supply of this nozzle with a second partial flow of the cleaning liquid via a arranged in the nozzle head independent supply channel.

A manufacturing technology simple and very compact planetary gear is realized according to a further proposal in each case by each planetary gear over its entire axial extent with a single continuous second Teeth is provided. It is waived to equip the respective planetary gear with two different gears, ie with two different numbers of teeth and different modules. In this regard, a different toothing is in the EP 0 560 778 B1 intended; the EP 1 062 049 B1 discloses with respect to the teeth of the respective planetary gear only equal numbers of teeth. The respective toothing of the planet gear engages with its one end in a first internally toothed ring gear and with its other end in a second internally toothed ring gear.

Due to the integration of the planetary gear in the area of the bevel gearbox, the first internally toothed ring gear fixedly connected to the stationary connection housing is inevitably located in this area. This quasi-projecting in this area first ring allows on its outside an additional storage of the nozzle head housing. For this purpose, in the area of a second housing opening formed in the nozzle head housing, which is arranged coaxially to the second axis of rotation, a sixth bearing designed as a ring-shaped plain bearing is provided, which serves to further support the first ring gear in the nozzle head housing about the first axis of rotation. The annular closed design of the plain bearing, which expediently consists of a metallic support ring and a sliding ring, gives this bearing sufficient stability, although in this area due to the presence of the second housing opening an all-round boundary is not given by the nozzle head housing to be stored.

In order to ensure the best possible jet formation of the first partial flow of cleaning liquid emerging from the nozzle in the nozzle head, another embodiment of the proposed container cleaning device provides that each nozzle in the nozzle head is connected to a respective inlet bore arranged in the latter, the respective longitudinal axis of the inlet bore being the tangent forms a concentric with the second axis of rotation circle with a certain radius and the latter is dimensioned so that the inlet bore forms a maximum length in the nozzle head.

The cleaning of the outside of the nozzle head housing by means of the nozzle head independently formed and also independently supplied via a supply channel nozzle is improved in that this outer side is directed to the circumferential, emerging from the nozzle third partial flow, on both sides and symmetrically to one through the first and the second axis of rotation extending plane, each having a slightly concave recess is provided, which has in each case opposite to the adjacent outer sides of the nozzle head housing transversely curved transitions. Due to the concave recess, at least some of the cleaning liquid applied to the outside in this area collects in the deepest region of the recess, in order to reach the rear housing end of the container cleaning device from here as liquid film adhering more or less adhering to the surface , Without the formation of such a concave recess, for example in the prevailing in the prior art all-round convex curvature of the outside of the nozzle head housing, the tendency for the applied cleaning liquid would tend to flow downwards or upwards and prematurely detach from the surface.

The container cleaning device 1 (Figures 1a to 1e) exists, based on the illustrated preferred mounting position ( FIGS. 1a, 1b , 1e), in its upper part of a housing body 2, an adjoining nozzle head housing 3 and a nozzle head 4 with at least one nozzle 19. In the embodiment, four of these nozzles 19 are provided which are arranged uniformly over the circumference of the nozzle head 4. The housing body 2 is composed in its upper region of a connection housing 2.1 with a supply line 2.1 d firmly connected to this, in which a feed opening 2.1 a is formed, and in its lower part of a first bevel gear 2.3 and a fixedly connected thereto at a distance first internally toothed ring gear 2.4, wherein the first bevel gear 2.3 and the first ring gear 2.4 are screwed to the latter via a fastening shaft 2.2 formed on the latter on the side of the connection housing 2.1. The connecting region between the first bevel gear 2.3 and the first ring gear 2.4 is designed to be permeable to liquid via a plurality of first passage openings 2.5 distributed over the circumference. The connection housing 2.1 can also be provided in two further variants (2.1 *, FIGS. 3a to 3c ; 2.1 **, FIGS. 4 to 9 ) are configured.

The nozzle head housing 3 is designed as a hollow body, which extends in an expression of the first kind on the side of the connection housing 2.1 in a solid, preferably integrally connected to the nozzle head housing 3 housing shaft 3a. This housing shaft 3a forms on the inside a first housing opening 3b, via which there is a first access to the interior of the nozzle head housing 3. On the side of the nozzle head 4, the nozzle head housing 3 has a second housing opening 3 c, via which a second access to the interior of the nozzle head housing 3 is given. The unit consisting of the attachment shaft 2.2, the first bevel gear 2.3 and the first internally toothed ring gear 2.4, preferably one-piece unit, is inserted into the housing via the second housing opening 3c Düsenkopfgehäuse 3 introduced and connected by the first housing opening 3b with the brought up from above connection housing 2.1 positively and / or non-positively connected, preferably screwed.

He is each end rotatably mounted on the terminal housing 2.1 via a first slide ring 16a of a first slide bearing 16 and a second slide ring 17a of a second slide bearing 17 about the first axis of rotation and forms in the axial direction between these two slide bearings 16, 17 and in the radial direction between itself and the terminal housing 2.1 an annular space 13, which is connected via branch channels 2.1 b in the wall of the connection housing 2.1 with the supply port 2.1a in combination. The slip rings 16a, 17a are expediently dimensioned radially in such a way that, due to the respective bearing gap given to them, a minimal passage of liquid corresponding to the effective pressure differences takes place in the sense of self-cleaning of these areas. Via the first slide bearing 16, this liquid transport also continues via the first bearing 11. 1 into the interior of the nozzle head housing 3.

The second housing opening 3c in the nozzle head housing 3 is oriented coaxially with respect to the second axis of rotation II, which preferably intersects the first axis of rotation I and runs perpendicular thereto. About the second housing opening 3c is a second Bevel gear 5 introduced into the nozzle head housing 3. The second bevel gear 5 is arranged coaxially to the second axis of rotation II and it meshes with the first bevel gear 2.3.

Fixing ring and the nozzle head 4 is arranged. The second bevel gear 5 ends on the inside in a central hub 5a, which is bolted to the nozzle head 4.

In the axial continuation of the feed opening 2.1a, a turbine 6 is arranged within the connection housing 2.1 and the adjoining one-piece unit consisting of the attachment shaft 2.2, the first bevel gear 2.3 and the transition region to the first internally toothed ring gear 2.4, and coaxial to the first rotation axis I. which is driven by the flow energy of the container cleaning device 1 via the supply port 2.1a inflow inlet stream of the cleaning liquid R. The turbine 6, seen in the flow direction, consists of a fixedly connected to the stationary housing body 2 stator 6b with a plurality of vanes and a rotor 6a with a plurality of blades. The impeller 6a is mounted on a turbine shaft 7, on the one hand in the region of the stator 6b in a fifth bearing 12.3 and on the other hand in the region of a second internally toothed ring gear 10 which is fixedly disposed below the first internally toothed ring gear 2.4 within the nozzle head housing 3, via a third Bearing 12.1 stored.

The turbine shaft 7 carries at its end facing away from the stator 6b a gear formed as a sun gear 8 ( Figure 1c ), which meshes with a planetary gear 9 consisting of at least two planetary gears. The planetary gears are each provided over their entire axial extent with a single respectively continuous toothing, each planetary gear with one end in the fixedly connected to the terminal housing 2.1 first internally geared ring 2.4 and the other end in the latter coaxial, with the Düsenkopfgehäuse 3 firmly connected second internally toothed ring gear 10 engages. The two on the inside about the sun gear 8 and the outside in the ring gears 2.4 and 10 rotating planetary gears, seen in the axial direction, on the one hand in the region of the third bearing 12.1 and on the other hand rotatably mounted on the turbine shaft 7 via a fourth bearing 12.2.

The mode of action of such a container cleaning device 1, which relates its drive energy via the turbines 6 acted upon by the flow energy of the cleaning agent, is sufficiently known from the prior art (eg EP 1 062 049 B1 ). Due to the difference in the number of teeth for the first internally toothed ring gear 2.4 and the second internally toothed ring gear 10, which must be at least one tooth, it comes with each full revolution of the planet gears to the sun gear 8 relative to a relative displacement of the ring gears 2.4 and 10 in its circumferential direction the first rotational axis I. This relative rotational displacement causes the rotatable second bevel gear 5 to rotate against the stationary first bevel gear 2.3 (rolling motion) and thus causes a rotation of the nozzle head 4 relative to the nozzle head housing 3 about the second rotational axis II with a second rotational speed n _II . whereby at the same time a rotation of the nozzle head housing 3 relative to the stationary housing body 2 about the first axis of rotation _{I is} generated at a first speed n _I.

In the housing shaft 3a, a first receiving bore 3f is provided, which serves to receive at least one first independent auxiliary nozzle 30. The latter can be firmly bonded in the receiving bore 3f (eg by welding) or positively and / or non-positively (eg by screwing or by pressing). The embodiment shows the first auxiliary nozzle 30 in the form of a flat jet nozzle. The latter is connected via the annular space 13 and the branch channels 2.1 b with the supply port 2.1 a in connection and it brings a fed from the feed stream of the cleaning liquid R second partial flow R2 to the lateral surface of the container. Since the housing shaft 3a is fixedly connected to the nozzle head housing 3, the first auxiliary nozzle 30 inevitably rotates in synchronism with the nozzle head housing 3 about the first axis of rotation I. Here is the first auxiliary nozzle 30 so arranged on the circumference of the housing shaft 3a (see Figure 1d ), that a crossing of the exiting from the first auxiliary nozzle 30 second spray jets of the second partial stream R2 with a first nozzles R1 from the nozzle head 4 exiting first partial flow R1, the first jetting generated, is reliably avoided. If two additional nozzles 30 are to be provided on the housing shaft 3a, they are expediently arranged diametrically opposite one another, their axes of symmetry preferably being oriented at 90 degrees relative to the second axis of rotation II.

In an embodiment of the second type, the annular space 13 is limited relative to the surroundings via a first nozzle housing 14 ( Figures 2a, 2b and 2c ), which receives the first independent auxiliary nozzle 30 in a second receiving bore 14a. The first nozzle housing 14 is rotatably mounted on the connection housing 2.1, wherein the bearing takes place at its lower end via a third sliding ring 18a of a third sliding bearing 18, and it is in a form-locking entrainment with the nozzle head housing 3. This driving connection is realized in the embodiment such the first nozzle housing 14 has a first driver recess 14b at its lower end ( FIGS. 2b, 2c ), in which a recessed at the upper end of the nozzle head housing 3 driving pin 20 engages positively. The expression of the second type otherwise corresponds to the further construction and the mode of operation of the expression of the first kind.

The above-described embodiment of the second type undergoes a modification in that the nozzle housing is now bulged in the radial direction and in the axial direction, and thereby takes on the shape of a second nozzle housing 15 ( FIG. FIGS. 3a, 3b and 3c). This shape of shape leads to the correspondingly slimmer in the axial direction modified terminal housing 2.1 * and corresponding axially displaced modified branch channels 2.1b * and it now allows the formation of a first auxiliary nozzle 15a * the integrated form and possibly a second auxiliary nozzle 15b * of the integrated form respectively the wall of the second nozzle housing 15 itself ( FIGS. 3a, 3c ). The second nozzle housing 15 is in turn in a form-fitting Carrying connection with the nozzle head housing 3. This driving connection is realized corresponding to that on the first nozzle housing 14, wherein the second nozzle housing 15 has at its lower end a second Mitnehmerausnehmung 15c ( FIG. 3b ), in which the recessed at the upper end of the nozzle head housing 3 driving pin 20 engages positively.

The nozzle head housing 3 may additionally have at least one additional auxiliary nozzle 30.1, 30.2, 3d *, 3e * ( FIG. 1b ), which may be a second independent auxiliary nozzle 30.1 and a third independent auxiliary nozzle 30.2 and / or an integrated second auxiliary nozzle 3d * and an integrated third auxiliary nozzle 3e *. In the exemplary embodiment, two integrated additional nozzles 3d *, 3e * are provided. These are fed from a fourth substream R2.1 and a fifth substream R2.2 which, in addition to the first substream R1, likewise generate from the differential flow of cleaning liquid R-R2 impinging on the turbine 6. The additional nozzles 30.1, 30.2, 3d *, 3e * are generally aligned in such a way that the spray jets they emit emerge from the inner surface of the container. In the exemplary embodiment, the integrated second auxiliary nozzle 3d * is arranged in the transition region of the nozzle head housing 3 between its jacket region and its front-side boundary surface, this being the preferred arrangement point, since the most favorable geometric conditions are present here.

In addition, any position on the nozzle head housing 3 is suitable for the arrangement of the additional nozzles 30.1, 30.2, 3d *, 3e *, which has an unobstructed access to the interior of the nozzle head housing 3, relative to its axial extension region along the first axis of rotation I. Another possible point comes here, as the embodiment with respect to the integrated third auxiliary nozzle 3e * shows, the cladding region of the nozzle head housing 3 between the first bevel gear 2.3 and the first internally toothed ring 2.4 in question. Furthermore, this is the range of the second internally toothed ring gear 10 suitable conditionally.

The orientation of the respective additional nozzle 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e * in the region of the housing shaft 3a or the nozzle housing 14, 15 or the nozzle head housing 3 can be such that the line of action of the axis of symmetry of the respective additional nozzle first axis of rotation I intersects. However, the corresponding line of action of the axis of symmetry may also have a radial distance from the first axis of rotation I. It is crucial in the arrangement and orientation of the additional nozzles 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e *, that they bring their respective cleaning liquid R2, R2.1, R2.2 in any case to the lateral surface of the container ,

The additional nozzles 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e * are advantageously designed as flat jet nozzles, which produce a fan-like flat jet, wherein in a preferred embodiment, the extension surface of the flat jet is substantially parallel to the first axis of rotation I. , Such arranged in the upper region of the nozzle head housing 3 or on the housing shaft 3a or on the nozzle housings 14, 15 flat jet nozzles are suitable, in addition to the jacket region of the container and the upper bottom to detect as much as possible.

The independent auxiliary nozzle 30, 30.1, 30.2 is, as the Figures 1b . 1d , 1e, 2b and 2c show in the nozzle head housing 3 cohesively (eg by welding) or positively and / or non-positively attached (eg by screwing or by pressing). However, the additional nozzle of the integrated mold 15a *, 15b * or the integrated additional nozzle 3d *, 3e * can also be formed in each case by the wall of the second nozzle housing 15 or the nozzle head housing 3 or possibly the housing shaft 3a itself. In this case, the latter are aufzubohren according to the necessary nozzle size and on the outlet side of the spray jet is an additional cut to make, if a flat jet nozzle is provided.

From the feed stream of the cleaning liquid R, which flows via the feed opening 2.1 a to the interior of the connection housing 2.1, 2.1 * ( FIGS. 1a to 3c), the second partial flow R2 is branched off via the branch channels 2.1b, 2.1b *, which via the first independent auxiliary nozzle 30 or the additional nozzles of the integrated mold 15a *, 15b * to the lateral surface of the container in the form of a about the first axis of rotation I circulating so-called surge cleaning is applied. The differential flow of cleaning fluid R - R2 ( FIGS. 1a , 1b) flows through in full the stator 6b and the subsequent impeller 6a to divide from here, with a partial flow over the arranged above the planetary gear 9 first passages 2.5 and then via second passages 5b in the second bevel gear 5 the nozzle head 4 flows in and another Partial flow first flows through the planetary gear 9, to get from there in part via the second passage openings 5b in the nozzle head 4. Overall, the first partial flow R1 exits via the nozzles 19 of the nozzle head 4, wherein the nozzles 19 execute a superimposed spatial rotary movement and thereby the entire inner surface of the container is detected orbitally after a certain period of time.

Another partial flow passes via the first passage openings 2.5 above the planetary gear 9 as a fifth partial flow R2.2 in the additional nozzle 3e *, 30.2. From the part of the planetary gear 9 passing through a certain proportion passes as a fourth partial flow R2.1 in the additional nozzle 3d *, 30.1.

The cleaning liquid which flows through the second passage openings 5b in the second bevel gear 5 branches into the first partial flow R1 (first injection jets) and a third partial flow R3 (third injection jets) ( FIG. FIGS. 1d, 1e, 2c and 3c). The first partial flow R1 enters the nozzles 19 in the nozzle head 4, wherein all nozzles 19 together bring out the first partial flow R1 in the container to be cleaned. The third partial flow R3 passes to a spray device 4a designed as a nozzle, which is formed on the outer edge of the nozzle head 4, and acted on the one hand due to the rotation of the nozzle head 4 about the second axis of rotation II (second speed n _II ) the nozzle head housing 3 circumferentially. On the other hand, the nozzle head housing 3 performs a rotation about the first axis of rotation I (first rotational speed n _I ), so that the third partial flow R3 also repeatedly the Surface of the housing shaft 3a and the nozzle housing 14, 15 applied above the nozzle head housing 3 with cleaning liquid. The partial flows R2, R2.1, R2.2 from the additional nozzles 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e * run around the first axis of rotation I and continuously bombard the lateral surface of the container, whereby the object according to the invention learns their solution.

The container cleaning device 1 of FIGS. 4 to 7 and FIG. 9 has already been described in its outline above. In the following, therefore, reference will only be made to specific details which are either not described in the previously described figures of the drawing or which relate in particular to the self-cleaning of the container cleaning device 1.

At the in FIG. 4 illustrated embodiment, the nozzle head housing 3 ends just above the first sliding bearing 16, which acts as a radial bearing. In addition to the preferably designed as a ball bearing first bearing 11.I, which acts as an axial bearing, a second bearing point for the radial mounting of the nozzle head housing 3 is provided, which is an axial piece on the outside of the first internally toothed ring gear 2.4 in the form of a sixth bearing 31st is arranged. The latter is preferably designed as a ring-shaped closed plain bearing, which consists of a preferably metallic support ring 31 a and a third slide ring 31 b. Although this sixth bearing 31 is arranged in the region of the second housing opening 3c, it is enclosed by the nozzle head housing 3 except for this housing opening area and can thus serve its stable mounting on the first internally toothed ring gear 2.4 projecting into the inner area of the nozzle head housing.

Between the terminal housing of the second type 2.1 ** in conjunction with the mounting shank 2.2 and the first bevel gear 2.3 on the one hand and the nozzle head housing 3 in this area on the other hand, a first circumferential annular gap 32 is formed, the interior of the nozzle head housing 3 via the first bearing 11.I with the Environment of the container cleaning device 1 connects. In the course of this first circumferential ring gap 32 is before its exit into the environment of the Container cleaning device 1, the first slide ring 16a of the first sliding bearing 16 is arranged.

The bearing of the second bevel gear 5 via the preferably designed as a ball bearing second bearing 11. II, which is held on the one hand by the second bevel gear 5 and on the other hand by a screwed into the second housing opening 3 c mounting ring 21.

Between the nozzle head 4 on the one hand and the mounting ring 21 in conjunction with a second housing opening 3c comprehensive, not designated edge of the nozzle head housing 3 on the other hand, a second circumferential annular gap 33 is formed, which connects the interior of the nozzle head housing 3 with the environment of the container cleaning device 1. In the course of this second circumferential annular gap 33, a fourth sliding ring 23a is arranged before its exit into the environment of the container cleaning device 1, which forms a fourth slide bearing 23 in the nozzle head housing 3 in conjunction with the fastening ring 21 on the one hand and the nozzle head 4 on the other hand with respect to their common second axis of rotation II. The fourth slide bearing 23 realizes the second bearing point for the second bevel gear 5 in conjunction with the nozzle head 4 within the nozzle head housing 3.

The second internally toothed ring gear 10 is introduced in the course of assembly of the container cleaning device 1 via the second housing opening 3c in the interior of the nozzle head housing 3 and fixed immovably in its end position via a fastener 22, such as a grub screw in the nozzle head housing 3.

The first planetary gear 9.1 and the second planetary gear 9.2 are each provided over their entire axial extent with a single respectively continuous second toothing, each planetary 9.1, 9.2 with the an end in the with the connector housing of the second kind 2.1 ** firmly connected first internally toothed ring gear 2.4 and the other end in the latter coaxial, with the nozzle head housing 3 firmly connected second internally toothed ring gear 10 engages. The sun gear 8 with the first toothing is executed with a number of teeth z ₈ = 6, while the two identically designed planet gears 9.1 and 9.2 are each provided with the second toothing (number of teeth z _9.1 = z _9.2 = 22). The first internally toothed ring gear 2.4 has a third toothing (number of teeth z _2.4 = 50) and the second internally toothed ring gear 10 has a fourth toothing (tooth number z ₁₀ = 52).

The cleaning liquid R flowing in via the feed opening 2.1 a into the interior of the connection housing of the second type 2.1 ** flows through the guide wheel 6b with the guide vanes 6b * and the following impeller 6a with the moving blades 6a * in order to divide from here, wherein a Partial flow via the arranged above the planetary gear 9 through openings 2.5 the nozzle head 4 flows directly and another partial flow first flows through the planetary gear 9, from there, also via the passage openings 2.5 in the second bevel gear 5, to get into the nozzle head 4. In this case, the teeth of the bevel gears 2.3 and 5, the teeth of the planetary gear 8, 9, 2.4 and 10, the bearings 12.1, 12.2 and 12.3 of the turbine shaft 7, the sixth bearing 31 of the nozzle head housing 3 and the second bearing 11.II of the nozzle head 4th from these partial flows of the cleaning liquid R acted upon.

The first circumferential annular gap 32 with its first sliding bearing 16 and the second circumferential annular gap 33 with its fourth sliding bearing 23 have a limited clearance for cleaning fluid r4 (first sliding bearing leakage) or r5 (second sliding bearing leakage) determined by the respective bearing clearance, which is sufficient in each case around these areas sufficiently clean. In this case, the first bearing 11.1 arranged upstream of the first circumferential ring gap 32 also experiences a sufficient application of cleaning fluid, so that good self-cleaning also takes place in this area.

Those cleaning liquid R or R - R2 (the differential flow R - R2 is present when the second partial flow R2 is branched off before the turbine 6), which flows through the passage openings 5b in the second bevel gear 5 (see FIG. 7 ), branches into the first partial flow R1 (first spray jets) and the third partial flow R3 (third spray jets). The first partial flow R1 passes via a connection bore 4d into a supply bore 4c in the nozzle head 4, wherein in the exemplary embodiment four of these connection and supply bores 4d, 4c are provided and each of the supply bores 4c terminates at the end in the associated nozzle 19 (see also FIG FIG. 5 ) . All nozzles 19 bring together the first partial flow R1 in the container to be cleaned. The third partial flow R3 passes, seen in the flow direction, before reaching the fourth sliding bearing 23 in a separate feed channel 4b ( FIGS. 4 and 7 ), over which the spray device 4a designed as a nozzle is supplied, which is completely formed in the nozzle head 4.

At the nozzles 19 of the nozzle head 4, which are provided for the actual cleaning of the container, the first partial flow R1 (first injection jets) arrives, which is deducted from the cleaning liquid R (main flow) entering the container cleaning device 1 via the supply opening 2.1a all diverted to the nozzles 19 partial streams results. The third partial stream R3 exiting via the spraying device 4a is a planned, distinct third spraying jet, which on the one hand urges the nozzle head housing 3 circumferentially as a result of the rotation of the nozzle head 4 about the second rotational axis II (second rotational speed n _II ) (see in particular FIG FIGS. 5, 6 and 9 ) . On the other hand, the nozzle head housing 3 performs a rotation about the first axis of rotation I (rotational speed n _I ), so that the third partial stream R3 also repeatedly the surface of the terminal housing second type 2.1 ** and the housing shaft 3a ( FIGS. 1a to 1e ) or of the nozzle housing 14, 15 above the nozzle head housing 3 ( FIG. FIGS. 2a to 3c ) is charged with cleaning liquid.

The first and the second sliding bearing leakage r4, r5 produce no pronounced spray jets, but here is provided for a moderate self-cleaning from the inside to the outside, while the cleaning, if necessary, from the circumferential annular gaps 32 and 33 carried out or these supplied externally impurities from the third partial flow R3. The mode of action of the spray device 4a designed as a nozzle is illustrated in a special way by the illustrations of FIGS FIGS. 5, 6 and 9 clarified. In particular, the representation according to FIG. 9 shows that the third partial flow R3 emerging from the spray device 4a detects the exit region of the second circumferential annular gap 33.

In order to ensure optimum formation of the first spray jets of the first partial flow R1 exiting from the nozzles 19, the respective supply bore 4c is designed to be associated with the associated nozzle 19 with the greatest possible length ΔI ( FIG. 5 ), as illustrated by the drawing on a nozzle 19. This is achieved by the fact that the longitudinal axis of the inlet bore 4c forms the tangent to a circle K concentric with the second axis of rotation II with radius a. This radius a is made as large as possible while ensuring that the respective connection hole 4d does not engage with the adjacent supply hole 4c and the adjacent nozzle 19, respectively.

With a view to a sufficient self-cleaning of the container cleaning device 1 is obtained on the outside of a difficult to detect area on the nozzle head housing 3, which faces away from the nozzle head 4, you do not want, as for example in the container cleaning device according to EP 1 062 049 B1 the case is to install a separate nozzle in the upper part of the connection housing 2.1 **, 2.1, 2.1 *, which in turn would represent a cleaning problem.

In order to detect the problematic surface area of the nozzle head housing 3 with cleaning fluid with the third partial flow R3 emerging from the spray device 4a, the invention proposes that the outside of the nozzle head housing 3 (see in particular FIG FIGS. 5, 6 and 9 ) , on both sides and symmetrically to a through the first and the second axis of rotation I, II extending plane, each with a slightly concave recess 3 * is provided to the adjacent outer sides of the nozzle head housing 3 respectively has opposite curved transitions. In those phases of the cleaning process in which the third partial flow R3 in each case immediately concaves the concave recess 3 *, the cleaning liquid impinging there, in particular when it hits the outer regions of the concave recess 3 *, is caused by this particular shape of the surface, rather than flow to the lowest point of the concave recess 3 * to from there as adhering to the surface liquid film (see in particular FIG. 6 ) to the nozzle head area of the surface of the nozzle head housing 3 to flow.

A second embodiment of the container cleaning device 1 according to the invention ( FIG. 8 ) is distinguished from the first embodiment according to FIG. 4 characterized in that the first circumferential annular gap 32, in the region of its exit into the environment of the actuating device 1, is not oriented parallel to the first axis of rotation I, as shown in FIG FIG. 4 the case is, but has an at least perpendicular to the first axis of rotation I or even slightly inclined downward orientation. As a result, the first sliding bearing leakage r4 can flow out of the first circumferential annular gap 32 in the radial direction to the outside without hindrance. Furthermore, in the corresponding phases of the circulation process of the nozzle head 4, the third partial flow R3 exiting from the spray device 4a impinges directly on the first circumferential ring gap 32, so that a particularly effective cleaning of impurities can take place here. <u> REFERENCE LIST OF ABBREVIATIONS USED </ u> 1 Tank cleaning device 2 housing body 2.1 connection housing 2.1 * modified connection housing 2.1 ** Connection housing of the second kind 2.1a supply port 2.1b branch channel 2.1b * modified branch channel 2.1d feed 2.2 mounting shaft 2.3 first bevel gear 2.4 first internally toothed ring gear 2.5 first passage opening 3 Nozzle head housing 3 * concave recess 3a housing shaft 3b first housing opening 3c second housing opening 3d * integrated second auxiliary nozzle 3e * integrated third auxiliary nozzle 3f first receiving hole 4 nozzle head 4a sprayer 4b supply channel 4c feed bore 4d connection bore 5 second bevel gear 5a hub 5b second passage opening 6 turbine 6a Wheel 6a * blade 6b stator 6b * vane 7 turbine shaft 8th sun 9 planetary gear 9.1 first planetary gear 9.2 second planetary gear 10 second internally toothed ring gear 11.I first camp 11.II second camp 12.1 third camp 12.2 fourth camp 12.3 fifth camp 13 annulus 14 first nozzle housing 14a second mounting hole 14b first Mitnehmerausnehmung 15 second nozzle housing 15a * first auxiliary nozzle of the integrated mold 15b * second auxiliary nozzle of the integrated mold 15c second Mitnehmerausnehmung 16 first sliding bearing 16a first sliding ring 17 second sliding bearing 17a second sliding ring 18 third plain bearing 18a third slip ring 19 jet 20 Carrier pin 21 fixing ring 22 fastener 23 fourth sliding bearing 23a fourth sliding ring 30 first independent additional nozzle 30.1 second independent additional nozzle 30.2 third independent additional nozzle 31 sixth camp 31a support ring 31b third slip ring 32 first circumferential annular gap 33 second circumferential annular gap A Drive means (eg parts 2.3, 2.4, 5, 6, 7, 8, 9, 10) K circle R Feed stream of cleaning fluid R1 first partial flow (first spray jets) R2 second partial flow (second spraying) R2.1 fourth partial flow (fourth spray jet) R2.2 fifth partial flow (fifth spray jets) R3 third partial flow (third spraying) a Radius of circles K .DELTA.I Length of the inlet hole 4c n _I first speed about the first axis of rotation I _II second speed about the second axis of rotation II r4 first sliding bearing leakage r5 second sliding bearing leakage z ₈ first toothing (number of teeth of sun gear 8) _9.1 second toothing (number of teeth of the first planetary gear 9.1) z _9.2 second toothing (number of teeth of the second planetary gear 9.2 (z _9.1 = z _9.2 )) _2.4 third toothing (number of teeth of the first internally toothed ring gear 2.4) z ₁₀ fourth toothing (number of teeth of the second internally toothed ring gear 10 (z ₁₀ -z _2.4 ≥ 1) I first axis of rotation II second axis of rotation
