Description
TECHNICAL FIELD
The invention relates to a receptacle cleaning device which is insertable into an opening of a receptacle and has a housing body, which has a connection housing connected with a feed line for cleaning fluid and arranged in a torque-proof manner with respect to the receptacle, as well as a nozzle head housing rotatable with respect to the connection housing around a first rotational axis, with at least one nozzle head arranged in a rotatable manner on the nozzle head housing around a second rotational axis and provided with at least one nozzle, wherein, during use, the nozzle(s) bring(s) out a first partial flow fed out of the intake flow of the cleaning fluid, and the rotational movement around the respective rotational axis is generated with drive means which are arranged within, on or outside the receptacle cleaning device and are possibly also arranged outside the receptacle and are driven by outside energy.
STATE OF THE ART A receptacle cleaning device of the generic type in which the drive means are arranged outside of the receptacle cleaning device and are driven by outside energy is described in DE 100 24 950 C1.
The top area of the non-rotatable, stationary housing part of the receptacle cleaning device according to the document EP 1 062 049 B1 additionally has a spray nozzle. With reference to the depicted position of the device, the spray direction of this additional spray nozzle is aligned downward toward the orbitally travelling nozzle arrangement to bring about the required self-cleaning. The cleaning of the receptacle itself is not improved or enhanced by this additional spray nozzle.
The mutual seal between the parts which move relative to each other of the known device according to EP 1 062 049 B1 is largely realized by preventing the cleaning fluid from exiting the interior of the receptacle cleaning device into its surroundings by the appropriate sealing elements. The joints between the parts that move relative to each other are problem areas critical to cleaning and can only be insufficiently subject to cleaning by the aforementioned spray nozzle. A receptacle cleaning device which is designed to be self-cleaning both inside and outside is known from EP 0 560 778 B1. In this document, a spraying device is provided whose nozzle head rotates about the second rotational axis and is designed in the shape of a shield which covers a part of the circumferential annular gap in the nozzle head and deflects the fluid which flows against the shield so that it cleans the outer surfaces of the housing of the receptacle cleaning device. This spraying device which also serves to self-clean the device is itself also incapable of improving the cleaning of the receptacle.
Since comparatively large-dimensioned, fluid-permeable circumferential annular gaps are arranged between the parts that move relative to each other of the receptacle cleaning device according to EP 0 560 778 B1, two relatively large partial flows from the flow passing through the device branch off from this circumferential annular gap which are in no longer available to the nozzles on the nozzle head for their actual job, that is, cleaning the receptacle. On the one hand, the amount of the partial flow exiting the entire perimeter of the respective circumferential annular gap is difficult to restrict to the necessary extent, and on the other hand, its relative size is largely dependent on the existing pressure conditions within the interior of the receptacle cleaning device which can be subject to fluctuations over time.
The supply of cleaning fluid to a spray device according to EP 0 560 778 B1, revolving with the nozzle head and designed in the form of a shield that covers a part of the circumferential annular gap in the nozzle head and deflects the fluid which flows against the shield so that it cleans the outer surfaces of the housing of the receptacle cleaning device, is problematic since this supply is particularly dependent on the pressure and flow conditions within the associated circumferential annular gap.
With the two aforementioned receptacle cleaning devices (EP 1 062 049 B1; EP 0 560 778 B1), the nozzles arranged on the respective nozzle head execute an overlapping, spatial rotary movement about two rotational axes, whereby the spray jets leaving these nozzles exert a particularly intense mechanical cleaning effect on the inner surface of the receptacle to be cleaned due to their orbital kinematics. Depending on the relationship between the speeds achieved about the two rotational axes, a typical spray pattern repeatedly generated at specific intervals in time results on the inner surface of the receptacle. In this regard, it was revealed that the intensive mechanical cleaning effect of the spray jets exiting the orbitally travelling spray nozzles effectively releases contaminants from the receptacle surface, but the applied amount of cleanser is frequently insufficient to quickly wash off the dissolved contaminants from the receptacle wall and feed them to the receptacle outlet. In order to completely ensure that the released contaminants are entirely transported to the receptacle outlet, the receptacle cleaning device frequently remains in operation longer than would be necessary in view of the contaminants to be dissolved and released.
Furthermore, such receptacle cleaning devices are known in which a nozzle head provided with at least one nozzle revolves around a single rotational axis and thereby always revolves and splashes the inner wall of the receptacle at the same locations. The rotary movement of the nozzle head can be driven about the respective rotational axis by drive means which are arranged outside of the receptacle cleaning device as well as outside of the receptacle, and are driven by outside energy (such as an electric motor) (DE 1 869 413 U). DE 26 45 401 C2 describes a receptacle cleaning device with the aforementioned kinematic features whose drive means are arranged outside of the receptacle and are driven by the flow energy of the feed flow of the cleaning fluid flowing into the receptacle cleaning device.
Finally, a receptacle cleaning device with the kinematic features under discussion is known from DE 102 08 237 C1, wherein the drive means for generating the rotary movement of the nozzle head are arranged entirely within the receptacle cleaning device and are driven by the flow energy of the feed flow of the cleaning fluid flowing into the receptacle cleaning device.
These three receptacle cleaning devices selected above as examples (DE 1 869 413 U; DE 26 45 401 C2; DE 102 08 237 C1) do indeed apply sufficient quantities of cleaning fluid on the inner wall of the receptacle, however the cleaning effect of nozzles which rotate about a single rotational axis and whose spray jets always contact the same places of the receptacle is generally insufficient with regard to an effective and economical cleaning of the entire receptacle.
The object of the present invention is to improve the receptacle cleaning device of the generic type so that it additionally produces a particularly intensive cleaning effect covering all the receptacle areas within a shorter time, wherein the receptacle cleaning device is designed to be very spatially compact and possesses optimum interior and exterior self-cleaning properties.
SUMMARY OF THE INVENTION
The object is solved by a receptacle cleaning device with the features of claim 1. Advantageous embodiments of the proposed receptacle cleaning device are the subject of the dependent claims.
The key inventive concept of the solution is that at least one additional nozzle is arranged on the nozzle head housing that revolves around the first rotational axis, and it exclusively serves to clean the receptacle. This additional nozzle thereby significantly differs from known solutions in this regard (such as EP 1 062 049 B1) in which the additional nozzle is arranged in a stationary manner and exclusively performs the self-cleaning (exterior cleaning) of the receptacle cleaning device.
Since the additional nozzle according to the invention only revolves about the first rotational axis and thereby brings out a second partial flow fed out of the intake flow of the cleaning fluid to the inner lateral surface of the receptacle, this lateral surface is completely splashed with cleaning fluid in briefer intervals of time than is the case with the nozzles moving orbitally about the two rotational axes alone. The so-called splash cleaning discharged solely about a rotational axis runs down the lateral surface of the receptacle as a fluid film and thereby contributes in a particularly effective manner to a forced cleaning and to the accelerated removal of released contaminants.
The relevant drive means driven by outside energy can be arranged within (DE 102 08 237 C1), on or outside of the receptacle cleaning device, wherein an arrangement outside of the receptacle is also provided for the last-cited embodiment (DE 1 869 413 U; DE 26 45 401 C2).
The branching of the second partial flow achieves a particularly advantageous and simply designed realization of the first kind when, as provided, the second partial flow is fed to an annular space via at least one branching channel in the wall of the connection housing, which surrounds the connection housing on the outside, which gets its delimitation with respect to the surrounding area via a housing shaft designed on the nozzle head housing and rotatably mounted on the connection housing and which opens into the additional nozzle arranged in the housing shaft. The realization of the first kind is particularly recommendable when the so-called splash cleaning released about a rotational axis is provided by the additional nozzle according to the invention from the beginning as desired or necessary and in addition to the orbital cleaning by the nozzles on the nozzle head. A realization of the second kind according to the invention in this regard provides that the second partial flow is fed to an annular space via at least one branching channel in the wall of the connection housing, which surrounds the connection housing on the outside, which gets its delimitation with respect to the surrounding area via a first or a second nozzle housing and which opens into the additional nozzle arranged in the nozzle housing, wherein the nozzle housing is rotatably mounted on the connection housing and is in a form-fitting driving connection to the nozzle head housing. The realization of the second kind is particularly recom-mendable when the so-called splash cleaning by the additional nozzle according to the invention is optionally desired, or proves to be necessary only during ongoing operation of receptacle cleaning to ensure easy retrofitting of the additional nozzle.
In the above-described realization of the first or second type, the pressure and flow conditions of the first partial flow in the area of the nozzle head are not significantly influenced since in this regard the location of the branching of the second partial flow and its position relative to the drive means only play a subordinate role.
The above-described realization of the first or second kind remains largely without influence on the pressure and flow conditions in the area of the first partial flow to the nozzles on the nozzle head when the second partial flow branches off entirely before the drive means arranged within the receptacle cleaning device. This configuration is the most advantageous and preferred solution in the context of the invention.
An advantageous embodiment of the receptacle cleaning device according to the invention in combination with the realization of the first or second kind provides that the nozzle head housing also has at least one additional nozzle, wherein a maximum of two of these additional nozzles are generally provided. According to another proposal, the respective additional nozzle is arranged at one of the possible locations of the nozzle head housing which has free access to the inner space of the nozzle head housing, and namely with respect to its axial extension area along the first rotational axis. Possible locations in this regard are the surface area of the nozzle head housing and/or preferably the transitional area between the surface area of the nozzle housing and its front boundary surface.
As furthermore provided, the respective additional nozzle can be aligned such that the line of action of its symmetrical axis intersects with the first rotational axis. The line of action of the symmetrical axis can also have a radial distance from the first rotational axis. Key in the arrangement and alignment of the additional nozzles is that they transport the cleaning fluid to the lateral surface of the receptacle.
According to another proposal, the additional nozzles are advantageously designed as flat spray nozzles producing a fan-shaped flat spray jet, wherein in one preferred embodiment, the extension surface of the flat spray progresses mainly parallel to the first rotational axis.
It is particularly easy to design and arrange the additional nozzle if, as also proposed, it is formed by the wall of the nozzle head housing itself. For such an embodiment, that is, an additional nozzle of the integrated form, the second nozzle housing designed with a round body is particularly suitable. An additional embodiment in this regard, that is, an integrated additional nozzle, can be arranged in the transition area between the surface area of the nozzle head housing and its front boundary surface since particularly favourable geometric conditions exist at this location.
An additional proposal provides designing the additional nozzle as an independent component (independent additional nozzle) which is integrally attached (for example by welding) in the correspondingly drilled-out nozzle head housing. In this regard, it is furthermore provided to arrange the additional nozzle in the form of the independent component in a form- and/or force-fitting manner in the nozzle head housing. In this regard, screwing in or pressing in are cited. Such solutions are preferable over the integral connection or formation by the wall of the nozzle head housing itself when cleaning processes can be only optimized when the receptacle cleaning device is in operation, and a multiple experimental exchange of different additional nozzles may be necessary. A receptacle cleaning device with a design that is extremely spatially compact exists when the receptacle cleaning device has a planetary gear driven in a known manner by outside energy in conjunction with a bevel gear, which both generate the rotational movement about the respective rotational axis.
If, as provided in an additional proposal, the planetary gear of the receptacle cleaning device is arranged entirely in the area of the space which is enclosed by the two bevel wheels of the bevel gear with their respective outer diameter and in the direction of their respective rotational axis, and which forms a common spatial intersection of these enclosed spaces, it results in the most conceivably compact space of the receptacle cleaning device since the smallest possible axial extension of the receptacle cleaning device is achieved with this fully integrated arrangement. None of the receptacle cleaning devices that have become known in this regard has been successful in integrating the entire planetary gearing completely in the above-defined area within the bevel gear.
If, as provided in an advantageous embodiment, the first hollow wheel, as seen in direction of the first rotational axis, is arranged a distance away from the first bevel wheel, and several first passage openings arranged distributed over the circumference are provided in the connecting area between the first bevel wheel and the first hollow wheel, a majority of the cleaning fluid passing through the receptacle cleaning device viewed in the direction of flow can be diverted behind the first bevel wheel into the nozzle head without having to first at least partially flow through the planetary gear, as is the case with the receptacle cleaning device according to EP 0 560 778 B1. With the receptacle cleaning device according to EP 1 062 049 B1, the entire flow of cleanser must flow through the planetary gear, and therefore the greatest possible flow resistance exists in this case. Given the arrangement of the planetary gear according to the invention, the internal flow loss of cleaning fluid when passing through the receptacle cleaning device is reduced, wherein the partial flow of cleaning fluid which still flows through the planetary gear ensures sufficient cleaning thereof.
As provided in another proposal in each case, the first hollow wheel, the first bevel wheel and a fastening shaft continuing on the first bevel wheel on its side facing away from the hollow wheel usefully form a one-piece unit, which is connected in a form- and/or force-fitting manner, preferably screwed, with the connection housing. Such a one-piece unit can for example be produced as a cast part, or as a combined turned and milled part, and it significantly simplifies the construction as well as the installation of the receptacle cleaning device in this embodiment.
Economical handling of the cleaning fluid for the purpose of self-cleaning the two circumferential annular gaps is achieved without impairing the quality of said selfcleaning when, as in each case proposed in another embodiment of the receptacle cleaning device according to the invention, the permeability of this circumferential annular gap to cleaning fluid is limited to the extent that requires or respectively permits a slide bearing of paired parts of the receptacle cleaning device which are arranged to rotate relative to each other. In this regard, in the progression 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, a slide ring is arranged before each exit of these circumferential annular gaps into the surrounding area of the receptacle cleaning device and forms a first slide bearing for the two housings with respect to their common first rotational axis, and a second slide bearing for the parts with respect to their common second rotational axis.
As is known, the slide ring of a slide bearing forms the necessary bearing gaps with the neighbouring parts to enable a sliding movement while forming a fluid film (in this case, the cleanser). The amount of this cleaning fluid necessarily passing through the slide bearing is limited by the relatively narrow bearing gaps; it is, however, sufficient to subject this critical area to a self-cleaning. By means of this measure, an unnecessarily large branching of partial flows of cleaning fluid through the circumferential annular gaps is avoided without impairing their selfcleaning.
According to another proposal, the cleaning of the circumferential annular gap in the area between the respective slide bearing and the surroundings of the receptacle cleaning device is ensured by the spray device revolving with nozzle head. The latter is designed as a nozzle which is formed completely in the nozzle head. This nozzle is supplied with a second partial flow of cleaning fluid through an independent supply channel arranged in the nozzle head. A planetary gear that is easy to produce and very compact is realized according to another proposal in that each planetary wheel is provided over its entire axial extension with a single continuous second toothing. The respective planetary wheel is not equipped with two different toothings, i.e., with two different tooth counts and different modules. A different toothing in this regard is provided in EP 0 560 778 B1; in regard to the toothing of the respective planetary gear, EP 1 062 049 B1 only discloses the same tooth counts. The end of the respective toothing of the planetary wheel engages in a first internally toothed hollow wheel, and its other end engages in a second internally toothed hollow wheel.
By integrating the planetary gear in the area of the bevel gear, the first internally toothed hollow wheel securely connected to the fixed connection housing is also necessarily located in this area. This first hollow wheel which more or less extends into this area enables its outside to additionally bear the nozzle head housing. To this end, in the area of a second housing opening which is formed in the nozzle head housing and is arranged coaxially to the second rotational axis, a sixth bearing designed as an annular closed slide bearing is provided which serves to further bear the first hollow wheel in the nozzle head housing around the first rotational axis. The annular closed design of the slide bearing which usefully consists of a metal support ring and a slide ring provides this bearing with sufficient stability, even though the nozzle head housing to be borne does not provide a boundary on all sides in this area due to the presence of the second housing opening.
To ensure the most optimal jet formation of the first partial stream of cleaning fluid exiting the nozzle in the nozzle head, another embodiment of the proposed receptacle cleaning device provides that each nozzle in the nozzle head is connected in each case to an intake bore hole arranged in the nozzle head, wherein the respective longitudinal axis of the intake bore hole forms the tangent to a circle concentric to the second rotational axis with a specific radius, and the latter is dimensioned such that the intake bore hole forms a greatest possible length in the nozzle head.
The cleaning of the outside of the nozzle head housing with the nozzle independently formed on the nozzle head and also independently supplied by a supply channel is improved in that said outside, toward which the circulating partial flow exiting the nozzle is directed, is provided with a slightly concave recess on both sides and symmetrical to a plane running through the first and second rotational axis, the recess being provided with transitions curved oppositely tothe neighbouring outsides of the nozzle head housing. Due to the concave recess, at least part of the cleaning fluid applied to the outside in this area collects in the deepest area of the recess to travel from this location, as a fluid film more-or-less adhering to the surface, to the rear housing end of the receptacle cleaning device viewed in the direction of flow. If such a concave recess was not formed, such as with the convex curvature of the outside of the nozzle head housing consistently found in the prior art, the applied cleaning fluid would, rather, tend to flow downward or respectively upward and prematurely release from the surface.
BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
In depicting examples of the essential features of the invention, a receptacle cleaning device 1 will be consistently selected in an embodiment (Fig. 1 to 3c) in which the drive means A for generating the rotational movement around a respective rotational axis I, II are arranged within the receptacle cleaning device 1 (Fig. 1a, 1c, 1d), and are driven by the flow energy of at least part of the supply flow of cleaning fluid R flowing toward the receptacle cleaning device 1.
With respect to the depicted preferred installation position (Fig. 1a, 1b, 1e), the top area of the receptacle cleaning device 1 (Fig 1a to 1e) consists of a housing body 2, a nozzle head housing 3 connected thereto, and a nozzle head 4 with at least one nozzle 19. Four of these nozzles 19 are provided in the exemplary embodiment which are arranged evenly over the perimeter of the nozzle head 4. The top area of the housing body 2 is composed of a connection housing 2.1 with a feed line 2.1 d securely connected thereto in which an feed opening 2.1a is formed, and its bottom area consists of a first bevel wheel 2.3 and a first internally toothed hollow wheel 2.4 securely connected thereto at a distance, wherein the first bevel wheel 2.3 and the first hollow wheel 2.4 are screwed to the fastening shaft 2.2 formed on the wheels on the side facing the connection housing 2.1. The connection area between the first bevel wheel 2.3 and the first hollow wheel 2.4 is designed to be permeable to fluid through several passage openings 2.5 arranged distributed over the circumference. The connection housing 2.1 can furthermore be designed in two additional versions (2.1*, Fig. 3a to 3c; 2.1**, Fig. 4 to 9).
The nozzle head housing 3 is designed as a hollow body which, in a realization of the first kind, extends on the side of the connection housing 2.1 in a fixed housing shaft 3a, preferably connected as a single piece to the nozzle head housing 3. On the inside, this housing shaft 3a forms a first housing opening 3b by means of which a first access exists 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 3c which provides a second access to the interior of the nozzle head housing 3. The preferably single-part unit consisting of the fastening shaft 2.2, the first bevel wheel 2.3 and the first internally toothed hollow wheel 2.4 is introduced via the second housing opening 3c into the nozzle head housing 3, and is connected through the first housing opening 3b in a form- and/or force-fitting manner, preferably screwed, to the connection housing 2.1 introduced from above.
Between a recess (not shown) in the nozzle head housing 3 - surrounding the first housing opening 3b in the area of the transition between the nozzle head housing 3 and its housing shaft 3a - and the first bevel gear 2.3, a first bearing 11.1 is provided, preferably designed as a ball bearing (Fig. 1 b) which serves to rotatably bear the nozzle head housing 3 on the connection housing 2.1 about the first rotational axis I which runs coaxial to the connection housing 2.1 and its feed line 2.1 d. A second bearing point for the nozzle head housing 3 is provided slightly further in an axial direction on the outside of the first internally toothed hollow wheel 2.4 in the form of a bearing (not shown).
The first housing opening 3b of the housing shaft 3a encloses the connection housing 2.1. The housing shaft is rotatably mounted about the first rotational axis I on the connection housing 2.1 at the ends via a first slide ring 16a of a first slide bearing 16, or respectively a second slide ring 17a of a second slide bearing 17, and forms an annular gap 13 in an axial direction between these two slide bearings 16, 17, and in a radial direction between itself and the connection housing 2.1, the annular gap being connected to the feed opening 2.1a via branching channels 2.1 b in the wall of the connection housing 2.1. The slide rings 16a, 17a are usefully dimensioned radially such that a minimum amount of fluid passes through the bearing gap in them corresponding to the effective pressure differences for self-cleaning in these areas. By means of the first slide bearing 16, this transportation of fluid also continues over 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 coaxial to the second rotational axis II which preferably intersects the first rotational axis I and runs perpendicular thereto. A second bevel wheel 5 is introduced into the nozzle head housing 3 through the second housing opening 3c. The second bevel wheel 5 is coaxial to the second rotational axis II and engages with the first bevel wheel 2.3. The second bevel wheel 5 is borne on the left side by a second bearing 11.11, preferably designed as a ball bearing, which is held on the one hand by the second bevel wheel 5 and on the other hand by a fastening ring (not shown) screwed into the second housing opening 3c, and on the right side by a slide ring (not shown) which is arranged between the aforementioned fastening ring and the nozzle head 4. The second bevel wheel 5 terminates on the inside in a central hub 5a which is screwed to the nozzle head 4.
In an axial projection of the feed opening 2.1a, a turbine 6 is arranged within a connection housing 2.1 and the one-piece unit connected thereto and consisting of the connection shaft 2.2, the first bevel wheel 2.3 and the transition area to the first internally toothed hollow wheel 2.4, and is coaxial to the first rotational axis I, the turbine being driven by the flow energy of the feed flow of the cleaning fluid R flowing through the feed opening 2.1a to the receptacle cleaning device 1. Viewed in the direction of flow, the turbine 6 consists of a guide wheel 6b securely connected to the fixed housing body 2 and having several guide vanes and one rotor wheel 6a having a plurality of rotor vanes. The rotor wheel 6a is fastened to a turbine shaft 7 which, on the one hand, is mounted in the area of the guide wheel 6b in a fifth bearing 12.3 and, on the other hand, is mounted via a third bearing 12.1 in the area of a second internally toothed hollow wheel 10 that is securely arranged below the first internally toothed hollow wheel 2.4 within the nozzle head housing 3.
On its end facing away from the guide wheel 6b, the turbine shaft 7 bears a gear wheel (Fig. 1c) designed as a sun wheel 8 which meshes with a planetary gear 9 consisting of at least two planetary wheels. The planetary wheels are each provided with a single continuous toothing over their entire axial extension, wherein one end of each planetary wheel engages with the first internally toothed hollow wheel 2.4 securely connected to the connection housing 2.1, and the other end engages with the second internally toothed hollow wheel 10 that is coaxial to the first internally toothed hollow wheel and is securely connected to the nozzle head housing 3. The two planetary wheels revolving on the inside around the sun wheel 8 and on the outside in the hollow wheels 2.4 and 10 are rotatably mounted, viewed in the axial direction, on one hand in the area of the third bearing 12.1, and on the other hand on the turbine shaft 7 via a fourth bearing 12.2.
The mode of operation of such a receptacle cleaning device 1 which obtains its drive energy via the turbine 6 supplied with the flow energy of the cleanser is sufficiently known from the prior art (such as EP 1 062 049 B1). Given the difference in the tooth count of the first internally toothed hollow wheel 2.4 and the second internally toothed hollow wheel 10 which must have at least one tooth, the hollow wheels 2.4 and 10 experience a relative shift in their peripheral direction with respect to the first rotational axis I upon each full revolution of the planetary wheels about the sun wheel 8. This relative rotational shift causes the rotatable second bevel wheel 5 to rotate on the fixed first bevel gear 2.3 (roll-off movement), and thereby causes the nozzle head 4 to rotate relative to the nozzle head housing 3 about the second rotational axis II with a second rotational speed nn, whereby at same time a rotation of the nozzle head housing 3 relative to the fixed housing body 2 about the first rotational axis I is generated at a first speed ni.
In the housing shaft 3a, a first mounting hole 3f is provided which serves to accommodate at least one first independent additional nozzle 30. The latter can be secured integrally (for example by welding) or in a form fit and/or force fit (such as by screwing or pressing in) in the mounting hole 3f. The exemplary embodiment shows the first additional nozzle 30 in the form of a flat spray nozzle. The latter is connected via the annular gap 13 and the branching channels 2.1b to the feed opening 2.1a, and it brings out a second partial flow R2 onto the lateral surface of the receptacle supplied from the feed flow of the cleaning fluid R. Since the housing shaft 3a is securely connected to the nozzle head housing 3, the first additional nozzle 30 necessarily revolves in sync with the nozzle head housing 3 around the first rotational axis I. The first additional nozzle 30 is arranged on the perimeter of the housing shaft 3a (see Fig. 1 d) such that a crossing of the second spray jets of the second partial flow R2 leaving the first additional nozzle 30 with a first partial flow R1 which generates first spray jets leaving the nozzles 19 on the nozzle head 4 is reliably avoided. If two additional nozzles 30 are provided on the housing shaft 3a, they are usefully arranged lying diametrically opposed to each other, wherein their axes of symmetry are preferably oriented 90° relative to the second rotational axis II.
In a realization of the second kind, the annular space 13 is delimited with respect to the surrounding area by means of a first nozzle housing 14 (Fig. 2a, 2b and 2c) which accommodates the first independent additional nozzle 30 in a second mounting hole 14a. The first nozzle housing 14 is rotatably mounted on the connection housing 2.1, wherein it is borne on its bottom end by a third slide ring 18a of a third slide bearing 18, and it is engaged in a form-fitting driving connection with the nozzle head housing 3. This driving connection is realized in the exemplary embodiment in that the bottom end of the first nozzle housing 14 has a first driver seat 14b (Fig. 2b, 2c) in which a driver pin 20 introduced into the top-end of the nozzle head housing 3 engages in a form fit. The realization of the second kind otherwise corresponds to the realization of the first kind with respect to the additional structure and mode of operation.
The realization of the second kind depicted above undergoes modification in that the nozzle housing is designed with a round body in the radial direction and is therefore squat in an axial direction and thereby assumes the shape of a second nozzle housing 15 (Fig. 3a, 3b and 3c). This shape leads to the connection housing 2.1* which is correspondingly modified to be more squat in an axial direction, and modified branching channels 2.1 b* which are correspondingly axially shifted, and they then permit the formation of a first additional nozzle 15a* of the integrated shape, and possibly a second additional nozzle 15b* of the integrated shape through the wall of the second nozzle housing 15 itself (Fig. 3a, 3c). The second nozzle housing 15 is in turn in a form-fit driving connection with the nozzle head housing 3. This driving connection is realized corresponding to the driving connection on the first nozzle housing 14, wherein the bottom end of the second nozzle housing 15 has a second driver seat 15c (Fig. 3b) in which a driver pin 20 introduced into the top-end of the nozzle head housing 3 engages in a form fit.
The nozzle head housing 3 can additionally have at least one more additional nozzle 30.1, 30.2, 3d*, 3e * (Fig. 1b) which can be a second independent additional nozzle 30.1, and a third independent additional nozzle 30.2 and/or an integrated second additional nozzle 3d*, and an integrated third additional nozzle 3e*. In the exemplary embodiment, two integrated additional nozzles 3d*, 3e* are provided. These are fed from a fourth partial flow R2.1 and a fifth partial flow R2.2 that, in addition to the first partial flow, are generated from the differential flow of cleaning fluid R - R2 contacting the turbine 6. The additional nozzles 30.1,30.2, 3d*, 3e* are generally aligned such that the spray jets emitted by them exit at the internal lateral surface of the receptacle. In the exemplary embodiment, the integrated second additional nozzle 3d* is arranged in the transition area of the nozzle head housing 3 between its surface area and its front delimiting surface, wherein this is the preferred arranged position in view of the favourable geometric situation at this location.
Any position of the nozzle head housing 3 is suitable for the arrangement of the additional nozzles 30.1, 30.2, 3d*, 3e* which possesses an unrestricted access to the interior of the nozzle housing 3 with respect to its axial area of extension along the first rotational axis I. The surface area of the nozzle head housing 3 between the first bevel wheel 2.3 and the first internally toothed hollow wheel 2.4 is another possible location in this regard as shown by the exemplary embodiment with respect to the integrated third additional nozzle 3e*. Furthermore, the area of the second internally toothed wheel 10 is conditionally suitable for this.
The respective additional nozzle 30, 30.1, 30.2, 15a*, 15b*, 3d*, 3e* in the area of the housing shaft 3a or the nozzle housing 14, 15, or the nozzle head housing 3, can be aligned such that the line of action of the symmetrical axis of the respective additional nozzle intersects the first rotational axis I. The corresponding line of action of the symmetrical axis can also have a radial distance from the first rotational axis I. Key in the arrangement and alignment of the additional nozzles 30, 30.1,30.2,15a*, 15b*, 3d*, 3e* is that they transport their respective cleaning fluid R2, R2.1, R2.2 to the lateral surface of the receptacle.
The additional nozzles 30, 30.1, 30.2, 15a*, 15b*, 3d*, 3e* are advantageously designed as flat spray nozzles, which generate a fan-like flat spray, wherein in one preferred embodiment, the extension surface of the flat spray progresses mainly parallel to the first rotational axis I. The flat spray nozzles arranged in the top area of the nozzle head housing 3, or respectively on the housing shaft 3a, or on the nozzle housings 14, 15, are suitable for reaching nearly all of the upper floor of the receptacle in addition to its surface area.
As shown in Fig. 1b, Id, 1e, 2b and 2c, the independent additional nozzle 30, 30.1,30.2 is integrally attached in the nozzle head housing 3 (such as by welding) or by a form and/or force-fit (such as by screwing or pressing in). The additional nozzle of the integrated shape 15a*, 15b*, or respectively the integrated additional nozzle 3d*, 3e* can however also be formed by the wall of the second nozzle housing 15, or respectively the nozzle head housing 3, or respectively the housing shaft 3a itself. In this case, the latter are to be drilled out corresponding to the required nozzle size, and additional milling is to be performed on the outlet side of the spray jet if a flat spray nozzle is to be provided.
From the feed flow of the cleaning fluid R which flows through the feed opening 2.1a to the interior of the connection housing 2.1,2.1* (Fig. 1a to 3c), the second partial flow R2 branches off through the branching channels 2.1b, 2.1b* which is brought out via the first independent additional nozzle 30, or respectively the additional nozzles of the integrated shape 5a*, 15b*, to the lateral surface of the receptacle in the form of a so-called splash cleaning rotating about the first rotational axis I. The differential flow of cleaning fluid R - R2 (Fig. 1a, 1b) entirely flows through the guide wheel 6b and the subsequent rotor wheel 6a and subsequently divides at this location, wherein a partial flow via the first passage openings 2.5 arranged above the planetary gear 9 and then via the second passage openings 5b in the second bevel wheel 5 flows to the nozzle head 4, and an additional partial flow first flows through the planetary gear 9 and subsequently passes in part from there through the second passage openings 5b into the nozzle head 4. The entire first partial flow R1 exits the nozzles 19 of the nozzle head 4, wherein the nozzles 19 execute an overlapping, spatially rotating movement and thereby orbitally reach the entire inner surface of the receptacle after a certain length of time.
An additional partial flow passes through the first passage openings 2.5 above the planetary gear 9 as a fifth partial flow R2.2 into the additional nozzle 3e*, 30.2. A certain portion from the partial flow passing through the planetary gear 9 reaches the additional nozzle 3d*, 30.1 as a fourth partial flow R2.1.
The cleaning fluid which flows through the second passage openings 5b in the second bevel wheel 5 branches into the first partial flow R1 (first spray jets) and a third partial flow R3 (third spray jets) (Fig. Id, 1e, 2c and 3c). The first partial flow R1 enters the nozzles 19 in the nozzle head 4, wherein all the nozzles 19 together bring out the first partial flow R1 into the receptacle to be cleaned. The third partial flow R3 reaches a spray device 4a designed as a nozzle which is formed on the outer edge of the nozzle head 4 and revolvingly impinges upon the nozzle head housing 3 on the one hand as a result of the rotation of the nozzle head 4 about a second rotational axis II (second rotational speed nn). On the other hand, the nozzle head housing 3 executes a rotation about the first rotational axis I (first rotational speed ni) so that the third partial flow R3 always repeatedly impinges upon the surface of the housing shaft 3a, or respectively the nozzle housing 14, 15 above the nozzle head housing 3, with cleaning fluid. 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 rotational axis I and splash the lateral surface of the receptacle continuously, thereby solving the objective according to the invention.
The basic features of the receptacle cleaning device 1 in Fig. 4 to 7 and Fig. 9 have already been described above. In the following, only special details will therefore be referenced which either are not identified in the previously described figures, or that relate in particular to the self-cleaning of the receptacle cleaning device 1.
In the embodiment depicted in Fig. 4, the nozzle head housing 3 terminates shortly above the first slide bearing 16 which functions as a radial bearing. In addition to the first bearing 11.1 preferably designed as a ball bearing and functioning as an axial bearing, a second bearing site is provided for the radial bearing of the nozzle head housing 3 which is arranged slightly further in an axial direction on the outside of the first internally toothed hollow wheel 2.4 in the form of a sixth bearing 31. The latter is preferably designed as an annular closed slide bearing which consists of a preferably metal support ring 31a and a third slide ring 31b. Although this sixth bearing 31 is arranged in the area of the second housing opening 3c, it is enclosed by the nozzle head housing 3 except for this housing opening area and can accordingly serve to stably bear it on the first internally toothed hollow wheel 2.4 extending into the interior of the nozzle head housing.
Between the connection housing of the second kind 2.1** in conjunction with the fastening shaft 2.2 and the first bevel wheel 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 that connects the interior of the nozzle head housing 3 via the first bearing 11.1 to the surroundings of the receptacle cleaning device 1. Over the course of this first circumferential annular gap 32, the first slide ring 16a of the first slide bearing 16 is arranged before it exits into the surroundings of the receptacle cleaning device 1.
The bearing of the second bevel wheel 5 is borne by the second bearing 11.11 which is preferably designed as a ball bearing and, on the one hand, is held by the second bevel wheel and, on the other hand, is held by a fastening ring 41 screwed into the second housing opening 3.
Between the nozzle head 4 on the one hand and the fastening ring 21 in conjunction with an edge of the nozzle head housing 3 (not shown) surrounding the second housing opening 3c on the other hand, a second circumferential annular gap 33 is formed that connects the interior of the nozzle head housing 3 to the surroundings of the receptacle cleaning device 1. A fourth slide ring 23a is arranged over the course of this second circumferential annular gap 33 before it exits into the surroundings of the receptacle cleaning device 1, the slide ring forming 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 rotational axis II. The fourth slide bearing 23 realizes the second bearing site for the second bevel wheel 5 in conjunction with the nozzle head 4 within the nozzle head housing 3.
The second internally toothed hollow wheel 10 is introduced through the second housing opening 3c into the interior of the nozzle head housing 3 during installation of the receptacle cleaning device 1, and it is immovably fixed in its end position by a fastening element 22, for example a set screw, in the nozzle head housing 3.
The sun wheel 8 meshes with the planetary gear 9 consisting of at least two planetary wheels 9.1, 9.2. The first planetary wheel 9.1 and the second planetary wheel 9.2 are each provided with a single continuous second toothing over their entire axial extension, wherein one end of each planetary wheel 9.1,9.2 engages with the first internally toothed hollow wheel 2.4 securely connected to the connection housing of the second kind 2.1**, and the other end engages with the second internally toothed hollow wheel 10 that is coaxial to the first internally toothed hollow wheel and is securely connected to the nozzle head housing 3. The sun wheel 8 with the first toothing is designed with a tooth count of zs = 6, whereas the two equivalently designed planetary wheels 9.1 and 9.2 are each provided with the second toothing (tooth count of Z9.1 = Z9.2 = 22). The first internally toothed hollow wheel 2.4 has a third toothing (tooth count of Z2.4 = 50), and the second internally toothed hollow wheel 10 has a fourth toothing (tooth count of Z10 = 52).
The cleaning fluid R flowing through the feed opening 2.1a into the interior of the connection housing of the second kind 2.1** entirely flows through the guide wheel 6b with the guide vanes 6b* and the subsequent rotor wheel 6a with the rotor vanes 6a* and subsequently divides at this location, wherein a partial flow via the passage openings 2.5 arranged above the planetary gear 9 immediately flows to the nozzle head 4, and an additional partial flow first flows through the planetary gear 9 and subsequently passes in part from there through the second passage openings 2.5 in the second bevel wheel 5 into the nozzle head 4. The toothings of the bevel wheels 2.3 and 5, the toothings 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 receive these partial flows of cleaning fluid R.
The first circumferential annular gap 32 with its first slide bearing 16, and the second circumferential annular gap 33 with its fourth slide bearing 23, possess a limited permeability, determined by the respective bearing play, to the cleaning fluid r4 (first slide bearing leakage), or respectively r5 (second slide bearing leakage) which is enough to sufficiently clean these areas. The first bearing 11.1 in front of the first circumferential annular gap 32 also undergoes sufficient contact with cleaning fluid so that effective self-cleaning also occurs in this area.
The cleaning fluid R, or respectively R - R2 (the differential flow R - R2 exists when the second partial flow R2 branches off upstream of the turbine 6) which flows through the passage openings 5b in the second bevel wheel 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 through a connection bore hole 4d into an infeed bore hole 4c in the nozzle head 4, wherein four of these connection and infeed bore holes 4d, 4c are provided in the exemplary embodiment, and each of the infeed bore holes 4c terminates at the end in the associated nozzle 19 (see also Fig. 5). All of the nozzles 19 together bring out the first partial flow R1 into the receptacle to be cleaned. Viewed in the direction of flow, the third partial flow R3, before reaching the fourth slide bearing 23, passes into an independent infeed channel 4b (Fig. 4 and 7) which supplies the spray device 4a formed as a nozzle which is entirely formed in the nozzle head 4.
Accordingly, the first partial flow R1 (first spray jets) arrive at the nozzles 19 of the nozzle head 4 which are provided to actually clean the receptacle, the first partial flow resulting from the cleaning fluid R (main flow) entering the receptacle cleaning device 1 through the feed opening 2.1a minus all of the partial flows branching up to the nozzles 19. The third partial flow R3 exiting the spray device 4a comprises intentional, distinct third spray jets which on the one hand contact the nozzle head housing 3 circumferentially resulting from the rotation of the nozzle head 4 about the second rotational axis II ( second rotational speed nn) (see in particular Fig. 5, 6 and 9). On the other hand, the nozzle head housing 3 executes a rotation about the first rotational axis I (rotational speed m) so that the third partial flow R3 also repeatedly applies cleaning fluid to the surface of the connection housing of the second kind 2.1**, or respectively the housing shaft 3a (Fig. 1a to 1e), or the nozzle housing 14, 15 above the nozzle head housing 3 (Fig. 2a to 3c).
The first and second slide bearing leakage r4, r5 do not generate forceful spray jets; rather, in this case a moderate self-cleaning from the inside out is provided, whereas the cleaning of contaminants discharged from the circumferential annular gaps 32 and 33 or supplied to them from the outside is carried out by the third partial flow R3. The mode of action of the spray device 4a designed as a nozzle is specially illustrated by the representations in Fig. 5, 6 and 9. In particular, the representation according to Fig. 9 shows that the third partial flow R3 exiting the spray device 4a involves the outlet area of the second circumferential annular gap 33.
To ensure an optimum formation of the first spray jets of the first partial flow R1 exiting the nozzles 19, the respective infeed bore hole 4c to the associated nozzle 19 is designed with the largest possible length ΔΙ (Fig. 5) as illustrated by a nozzle 19 in the drawing. This is accomplished in that the longitudinal axis of the intake bore hole 4c forms the tangent on a circle K with radius "a" concentric to the second rotational axis II. This radius "a" is designed to be as large as possible which ensures that the respective connection bore hole 4d does not engage in the adjacent infeed bore hole 4c, or respectively the adjacent nozzle 19.
In pursuing sufficient self cleaning of the receptacle cleaning device 1, there is a difficult-to-reach area on the nozzle head housing 3 on the outside of the receptacle cleaning device which is facing away from the nozzle head 4, if there is no desire to install a separate nozzle in the top area of the connection housing 2.1**, 2.1,2.1 * which in turn would constitute a technical cleaning problem, as for example is the case with the receptacle cleaning device according to EP 1 062 049 B1.
In order to reach the relevant problematic surfaces of the nozzle head housing 3 with cleaning fluid by means of the third partial flow R3 exiting the spray device 4a, the invention proposes that the outside of the nozzle head housing 3 (see in particular Fig. 5, 6 and 9) be provided on both sides and symmetrical to a plane running through the first and second rotational axes I, II with a slightly concave recess 3* which has transitions curved oppositely to the neighbouring outsides of the nozzle head housing 3. In the phases of the cleaning process in which the third partial flow R3 directly splashes the concave recess 3*, the cleaning fluid contacting at that location, in particular when it contacts the outer areas of the concave recess 3*, tends to flow into the lowest point in the concave recess 3* due to this special surface shape in order to flow as a fluid film adhering to the surface (see in particular Fig. 6) to the area of the surface of the nozzle head housing 3 distant from the nozzle head. A second embodiment of the receptacle cleaning device 1 according to the invention (Fig. 8) is distinguished from the first embodiment according to Fig. 4 in that the first circumferential annular gap 32 at the area where it exits into the surroundings of the actuation device 1 is not oriented parallel to the first rotational axis I as is the case in Fig. 4, but rather has an orientation at least perpendicular relative to the first rotational axis I, or even angled slightly downward. This allows the first slide bearing leakage r4 to drain to the outside out of the first circumferential annular gap 32 without being hindered. Furthermore in the corresponding phases of the revolution of the nozzle head 4, the third partial flow R3 exiting the spray device 4a directly contacts the first circumferential annular gap 32, thus allowing a particularly effective cleaning of impurities to occur.
