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 the nozzle(s) deliver(s) 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 driven by the flow energy of the intake flow of the cleaning fluid flowing to the receptacle cleaning device, and with a turbine supplied with cleaning fluid, which forms a part of the drive means, wherein the turbine in connection with a planetary gear and a bevel gear generates the rotational movement around the respective rotational axis.
BACKGROUND OF THE INVENTION A receptacle cleaning device of the type defined in the preamble of claim 1, in which the drive means including the turbine are arranged within the receptacle cleaning device and the second partial flow is branched off before the drive means, is known from JP 08 080479 A. The turbine consists of an open rotor wheel arranged freely in the nozzle head housing, which is supplied from a partial flow of the intake flow of the cleaning fluid overall fed to the receptacle cleaning device in the form of a free jet exiting from a supply nozzle. The partial flow supplying the rotor wheel thus results from the intake flow of the cleaning fluid overall fed to the receptacle cleaning device less the first partial flow delivered via the nozzles and the second partial flow delivered via the auxiliary nozzle. The torque generated by the rotor wheel of the turbine is transmitted to a first bevel wheel connected in a torque-proof manner with the fixed housing body of the receptacle cleaning device via a multi-stage spur gear, on which a second bevel wheel rolls up, which is permanently connected with the nozzle head housing carrying the nozzles, and thereby rotates for one around the first rotational axis and also simultaneously and in a spatially superimposed manner around the second rotational axis.
This known receptacle cleaning device is constructively very complex and projecting because of the selection of multi-stage spur gears and because of the necessity of dividing the intake flow of the cleaning fluid not only into the two partial flows to the nozzles and the at least one auxiliary nozzle but also into a third partial flow for the supply of the rotor wheel and guiding the latter up to the supply nozzle in the form of a forced flow. Only the flow energy of the partial flow of the cleaning fluid flowing to the rotor wheel is available for generating the drive torque of the receptacle cleaning device. A receptacle cleaning device of the generic type, in which the driving means are arranged within the receptacle cleaning device and are driven by the flow energy of the intake flow of the cleaning fluid flowing to the receptacle cleaning device, is described in EP 1 062 049 B1.
The axial extension of the known receptacle cleaning device into the receptacle is relatively large. This results from the fact that the drive means, which are formed in the present case from a turbine, a planetary gear and a bevel gear, which is received in a nozzle head housing, as seen in the direction of flow of the cleaning fluid, are arranged in succession in the named sequence. The receptacle, in which for example this receptacle cleaning device is installed in a stationary manner, can only be filled up to shortly below the nozzle head housing reaching relatively far into the receptacle, since otherwise at least the nozzle head housing would dip into the medium stored in the receptacle. In any case, the known receptacle cleaning device offers in its outer area particularly large contact surfaces for dirt and thus requires self-cleaning there, if the receptacle cleaning device is used in hygienically sensitive areas of the process technology.
For this reason, the receptacle cleaning device according to publication EP 1 062 049 B1 additionally has a spray nozzle in the upper area of the torque-proof, stationary housing part. The spray direction of this additional spray nozzle is, in relation to the representation position of the device, pointed downwards in the direction of the orbitally unwinding nozzle arrangement, in order to effectuate here the required self-cleaning. The cleaning of the receptacle itself is not improved or intensified by this additional spray nozzle.
The mutual sealing of the parts of the known device moveable relative to each other according to EP 1 062 049 B1 takes place mainly in a manner such that a leakage of cleaning fluid from the interior of the receptacle cleaning device into its surroundings is prevented through suitable sealing elements. The separation joints of the parts moveable relative to each other thereby represent cleaning-critical problem areas, which by the aforementioned spray nozzle can only be subjected to a cleaning in an insufficient manner. A receptacle cleaning device of the generic type designed in a self-cleaning manner both inside and outside is known from EP 0 560 778 B1. A spray device revolving with the nozzle head around the second rotational axis is provided there, which is designed in the form of a shield, which covers a part of the circumferential annular gap present on the nozzle head, and deflects the liquid, which flows out against the shield, such that it cleans the outer surfaces of the housing of the receptacle cleaning device. This spray nozzle also serving the self-cleaning of the device can't improve the cleaning of the receptacle itself either.
Compared to the device according to EP 1 062 049 B1, the device according to EP 0 560 778 B1 has a reduced, axial extension, with respect to the installation depth in the receptacle, insofar as here the planetary gear engages at least partially in the area comprised by the bevel gear. But also in the case of this known device, a reduction reserve still remains unused with its axial extension in mind, which would permit a higher filling of the receptacle to be cleaned, for example with product, in the case of complete utilization.
Since relatively largely dimensioned, liquid-permeable circumferential annular gaps are arranged between the parts of the receptacle cleaning device according to EP 0 560 778 B1 that are moveable relative to each other, two relatively large partial flows are branched off from the flow of cleaning fluid penetrating the device via these circumferential annular gaps, which are then no longer available for the nozzles on the nozzle head for its actual job, namely the cleaning of the receptacle. On the one hand, it is difficult to limit the partial flow escaping over the entire circumference of the respective circumferential annular gap in its quantity to the necessary dimension, and on the other hand its respective size is considerably dependent on the respectively present pressure conditions in the interior of the receptacle cleaning device, which can be subject to temporal variations. A spray device rotating with the nozzle head according to EP 0 560 778 B1, which is designed in the form of a shield, which covers a part of the circumferential annular gap present on the nozzle head and deflects the liquid flowing out against the shield such that it cleans the outer surfaces of the housing of the receptacle cleaning device, is problematic with respect to its supply with cleaning fluid insofar as this supply depends in turn in a special manner on the pressure and flow conditions in the associated circumferential annular gap.
In the case of 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 a superimposed, spatial rotational movement around two rotational axes, whereby the spray jets exiting these nozzles deploy a particularly intensive mechanical cleaning effect on the interior surface of the receptacle to be cleaned due to their orbital kinematics. Depending on the ratio of the rotational speeds realized around the two rotational axes, a typical spray pattern continuously generated at certain time intervals results on the interior surface of the receptacle. It has been shown in this respect that the intensive mechanical cleaning effect of the spray jets exiting from the orbitally unwinding spray nozzles does release contaminants on the receptacle surface well, but that the cleanser quantity thereby deployed is often insufficient in order to wash the re leased contaminants off the receptacle wall rapidly and to feed them to the outlet of the receptacle. In order to ensure a complete transport of the released contaminants into the outlet of the receptacle, the receptacle cleaning device thus often remains in operation longer than should be necessary in principle with the contaminants to be dissolved and released in mind.
Moreover, receptacle cleaning devices are known, in which a nozzle head provided with at least one nozzle rotates around one single rotational axis and thereby flushes circumferentially the inner wall of the receptacle always at the same spots. The rotational movement of the nozzle head around the respective rotational axis can thereby be generated by drive means, which are arranged outside the receptacle cleaning device and also outside the receptacle and are driven by external energy (e.g. electric motor) (DE 1 869 413 U). DE 26 45 401 C2 describes a receptacle cleaning device with the above kinematic characteristics, the drive means of which are arranged outside of the receptacle and are driven by the flow energy of the intake flow of the cleaning fluid flowing to the receptacle cleaning device.
Finally, a receptacle cleaning device with the discussed kinematic characteristics is known from DE 102 08 237 C1, in which the drive means for generating the rotational movement of the nozzle head are arranged entirely inside of the receptacle cleaning device and are driven by the flow energy of the intake flow of the cleaning fluid flowing to the receptacle cleaning device. While these three known receptacle cleaning devices selected as examples above deliver sufficient amounts of cleaning fluid to the inner wall of the receptacle, the cleaning effect of nozzles, which rotate around a single rotational axis and the spray jets of which always hit the same spots of the receptacle, is however generally unsatisfactory in terms of 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 such that it deploys a particularly intensive cleaning effect encompassing all receptacle areas in a shorter period of time, wherein the re ceptacle cleaning device is designed in an extremely compact manner in terms of space and has optimal self-cleaning properties on the inside and outside.
SUMMARY OF THE INVENTION
This object is solved through a receptacle cleaning device with the characteristics of claim 1. Advantageous embodiments of the suggested receptacle cleaning device are the subject matter of the dependent claims.
The decisive inventive solution idea consists in that at least one auxiliary nozzle, which serves exclusively to clean the receptacle, is arranged on the nozzle head housing, which rotates around the first rotational axis. This auxiliary nozzle thus differs decisively from known related solutions (e.g. EP 1 062 049 B1), in which the auxiliary nozzle is arranged in a stationary manner and takes over exclusively the self-cleaning (outside cleaning) of the receptacle cleaning device.
Since the auxiliary nozzle according to the invention only rotates around the first rotational axis and thereby delivers a second partial flow to the inner shell surface of the receptacle, which is fed out of the intake flow of the cleaning fluid flowing to the receptacle cleaning device, this shell surface is flushed comprehensively with cleaning fluid in shorter time intervals, as is alone the case with the nozzles orbitally moved around the two rotational axes. The so-called flush cleaning delivered around a rotational axis runs down on the shell surface of the receptacle as a liquid film and thereby contributes in a particularly effective manner to a forced cleaning and to the accelerated discharge of loosened contaminants.
In the case of the solution according to the invention, the drive means are driven by the flow energy of the intake flow of the cleaning fluid flowing to the receptacle cleaning device. The respective drive means can thereby be arranged within (e g. EP 1 062 049 B1, EP 0 560 778 B1; DE 102 08 237 C1), on, or out side of the receptacle cleaning device, wherein in the last case an arrangement outside of the receptacle is also provided (DE 1 869 413 U; DE 26 45 401 C2).
Another inventive solution idea consists in that the second partial flow is branched out of the intake flow of the cleaning fluid, seen in the direction of flow, upstream of the drive means arranged within the receptacle cleaning device. This solution is particularly advantageous because the first partial flow flowing to the nozzles on the nozzle head is hereby impacted the least by the above branching and a sufficient volume flow is available there under pressure. The branching of the second partial flow outlined briefly above has a particularly advantageous and also simple, constructive design of a first type, when, as is 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 experiences its delimitation with respect to the surroundings via a housing shaft which is formed on the nozzle head housing and rotatably mounted on the connection housing and which runs to the auxiliary nozzle arranged in the housing shaft. The design of the first type is recommended in particular when the so-called flush cleaning delivered around a rotational axis by the auxiliary nozzle is to be provided from the start in a desired or necessary manner and in addition to the orbital cleaning by the nozzles on the nozzle head. A related design according to the invention of the second type 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 experiences its delimitation with respect to the surroundings via a first or a second nozzle housing and which runs to the auxiliary nozzle arranged in the nozzle housing, wherein the nozzle housing is rotatably mounted on the connection housing and is connected in a form-fitting driving connection with the nozzle head housing. The design of the second type is recommended in particular when the so-called flush cleaning through the auxiliary nozzle is optionally desired or only turns out to be necessary during operation of the receptacle cleaning so that a simple retrofitting of the auxiliary nozzle is ensured.
The design described above of a first or second type remains in its use on the embodiment described above mainly without impact on the pressure and flow conditions in the area of the first partial flow to the nozzles on the nozzle head.
An advantageous embodiment of the receptacle cleaning device according to the invention provides in the respective combination with the design of the first or second type that the nozzle head housing also has at least one additional auxiliary nozzle, wherein generally a maximum number of two of these auxiliary nozzles are provided. According to another suggestion, the respective auxiliary nozzle is thereby arranged on one of the possible spots on the nozzle head housing which have free access to the interior of the nozzle head housing, and namely with respect to its axial extension area along the first rotational axis. The shell area of the nozzle head housing and/or preferably the transition area of the nozzle head housing between its shell area and its front-side periphery hereby come into consideration as possible spots.
The alignment of the respective auxiliary nozzle can thereby take place, as is also provided, such that the line of action of its symmetrical axis intersects the first rotational axis. However, the line of action of the symmetrical axis can also have a radial distance from the first rotational axis. It is decisive for the arrangement and alignment of the auxiliary nozzles that they deliver their cleaning fluid in each case to the shell surface of the receptacle.
According to another suggestion, the auxiliary nozzles are advantageously designed as flat-spray nozzles, which generate a fan-like flat-spray, wherein the extension surface of the flat-spray progresses mainly parallel to the first rotational axis in a preferred embodiment.
The design and arrangement of the auxiliary nozzle is designed in a particularly simple manner when it, as is also suggested, is designed by the wall of the nozzle head housing itself. For this type of design, namely an auxiliary nozzle of the integrated form, the round-bodied second nozzle housing is particularly suitable. Another related design, namely an integrated auxiliary nozzle, can be arranged in a particularly simple manner in the transition area of the nozzle head housing between its shell area and its front-side periphery, since particularly beneficial geometric conditions exist there.
Another suggestion provides to design the auxiliary nozzle as an independent component (independent auxiliary nozzle) and to fasten it in surface-connected manner, through welding for example, in the correspondingly drilled-open nozzle head housing. Furthermore, it is provided in this regard to arrange the auxiliary nozzle in the form of an independent component in a form- and/or force-fitting manner in the nozzle head housing. This can take place by screwing in or pressing in for example. These types of solutions are to be preferred over the surface-connected fastening or the design through the wall of the nozzle head housing itself when cleaning processes can only be optimized during the operation of the receptacle cleaning device and multiple replacements of various auxiliary nozzles is required for this, if applicable experimentally.
If, as provided by another suggestion, the planetary gear of the receptacle cleaning device is arranged entirely in the area of the of the space defined by the two bevel wheels of the bevel gear with their respective outer diameter and in the direction of their respective rotational axes and which forms a common spatial intersection of these defined spaces, then the most conceivable compact space form of the discussed receptacle cleaning device then results, since the most minimal possible axial extension of the receptacle cleaning device is achieved through this fully integrated arrangement. None of the previously known receptacle cleaning devices succeeded in integrating the entire planetary gear completely into the area defined above within the bevel gear.
If, as respectively provided in an advantageous embodiment, the first hollow wheel seen in the direction of the first rotational axis is arranged a bit far from the first bevel wheel and several first passage openings arranged circumferen tially distributed in the connection area between the first bevel wheel and the first hollow wheel are provided, then a large portion of the cleaning fluid penetrating the receptacle cleaning device, as seen in the direction of flow, can already be diverted behind the turbine into the nozzle head, without first needing to pass through the planetary gear at least partially, as is the case in the receptacle cleaning device according to EP 0 560 778 B1. In the case of the receptacle cleaning device according to EP 1 062 149 B1, the planetary gear must be passed through in full by the entire cleanser flow so that the largest possible flow resistance is present here. Through the arrangement of the planetary gear according to the invention, the internal flow losses of the cleaning fluid during passage through the receptacle cleaning device are reduced, wherein the partial flow of cleaning fluid, which still passes through the planetary gear, ensures a sufficient cleaning of the same.
The first hollow wheel, the first bevel wheel and a fastening shaft continuing on the latter on its side facing away from the hollow wheel expediently form a one-piece unit, as provided by another suggestion, which is connected, preferably screwed, with the connection housing in a form- and/or force-fitting manner. Such a one-piece unit can be produced for example as a cast part or also as a combined turned and milled part and, in this design, it considerably simplifies the structure and also the assembly of the receptacle cleaning device.
An economical handling with cleaning fluid for the purpose of the self-cleaning of the two circumferential annular gaps is achieved without calling into question the quality of this self-cleaning when, as is suggested by another embodiment of the receptacle cleaning device according to the invention, these circumferential annular gaps are restricted respectively in their permeability for cleaning fluid to that degree, which demands or respectively permits a slide bearing of parts of the receptacle cleaning device that are paired with each other and that are arranged in a relatively rotatable manner with respect to each other. For this, it is provided that 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, respectively before exit of these circumferential annular gap into the surroundings of the receptacle cleaning device, a slide ring is respectively arranged, which 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 generally known, the slide ring of a slide bearing forms necessary bearing gaps with the neighboring parts so that a slide movement under formation of a liquid film (in this case, cleanser) is possible. The quantity of this cleaning fluid necessarily penetrating the slide bearing is restricted by the relatively narrow bearing gaps; but it is sufficient in order to submit this critical area to a self-cleaning. Through this measure, an unnecessarily large branching of partial flows of cleaning fluid via the circumferential annular gaps is avoided without calling their self-cleaning into question.
According to another suggestion, the cleaning of the circumferential annular gaps in the area between the respective slide bearing and the surroundings of the receptacle cleaning device is ensured by the spraying device rotating with the nozzle head. The spaying device is designed as a nozzle, which is designed completely in the nozzle head. The supply of this nozzle with a second partial flow of cleaning fluid takes place via an independent infeed channel arranged in the nozzle head.
According to another suggestion, a simple (from a production perspective) and very compact planetary gear is respectively realized in that each planetary wheel is provided with a single, continuous second toothing over its entire axial extension. The respective planetary wheel is not equipped with two different toothings, i.e. with two different numbers of teeth and different modules. This type of different toothing is provided in EP 0 560 778 B1; EP 1 062 049 B1 discloses only the same numbers of teeth in terms of the toothing of the respective planetary wheel. The respective toothing of the planetary wheel engages with its one end into a first internally toothed hollow wheel and with its other end into a second internally toothed hollow wheel.
Through the integration of the planetary gear in the area of the bevel gear, the first internally toothed hollow wheel permanently connected with the fixed connection housing is also inevitably located in this area. This first hollow wheel quasi extending into this area permits an additional mounting of the nozzle head housing on its outside. For this purpose, a sixth bearing designed as an annu-larly closed slide bearing, which serves the further mounting of the first hollow wheel in the nozzle head housing around the first rotational axis, is provided in the area of a second housing opening designed in the nozzle head housing, which is arranged coaxially to the second rotational axis. The annularly closed design of the slide bearing, which advantageously consists of a metallic support ring and a slide ring, gives this bearing sufficient stability, although a boundary on all sides through the nozzle head housing to be mounted is not given in this area due to the presence of the second housing opening.
In order to ensure the most optimal jet formation of the first partial flow of cleaning fluid exiting the nozzle in the nozzle head, another embodiment of the suggested receptacle cleaning device provides that each nozzle in the nozzle head is respectively connected with an intake hole arranged in the latter, wherein the respective longitudinal axis of the intake hole forms the tangent to a circle concentric to the second rotational axis with a certain radius and the latter is measured such that the intake hole forms the largest possible length in the nozzle head.
The cleaning of the outside of the nozzle head housing by means of the nozzle designed independently on the nozzle head and also independently supplied via an infeed channel is improved by this outside, towards which the rotating third partial flow exiting the nozzle is pointed, being provided on both sides and symmetrically to a plane progressing through the first and the second rotational axis respectively with a slightly concave recess, which has respectively oppositely bent transitions to the neighboring outsides of the nozzle head housing. Through the concave recess, at least a portion of the cleaning fluid applied to the outside in this area collects in the deepest area of the recess in order to make its way from here up to the rear housing end of the receptacle cleaning device, as seen in the direction of flow, as a liquid film more or less adhering to the surface. Without the formation of such a concave recess, for example in the bulge of the outside of the nozzle head housing on all sides prevalent in the state of the art, the applied cleaning fluid would rather tend to flow downwards or respectively upwards and prematurely detach from the surface.

DETAILED DESCRIPTION
For the exemplary representation of the invention, a receptacle cleaning device 1 in an embodiment is selected universally below (Figures 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 (Figures 1a, 1c, 1d) and are driven by the flow energy of a intake flow of the cleaning fluid R flowing to the receptacle cleaning device 1.
The receptacle cleaning device 1 (Figures 1a to 1e) consists, relating to the represented preferred installation position (Figures 1a, 1b, 1e), in its upper area of a housing body 2, a nozzle head housing 3 connecting to it and a nozzle head 4 with at least one nozzle 19. In the exemplary embodiment, four of these nozzles 19 are provided, which are arranged evenly over the circumference of the nozzle head 4. When mounted, the housing body 2 in its upper area is made up of a connection housing 2.1 with a feed line 2.1 d permanently connecting with it, in which an infeed opening 2.1a is designed and in its bottom area of a first bevel wheel 2.3 and a first internally toothed hollow wheel 2.4 permanently connecting to it at a distance, wherein the first bevel wheel 2.3 and the first hollow wheel 2.4 are screwed with the connection housing 2.1 via a fastening shaft 2.2 designed on them on the side of the connection housing 2.1. The connection area between the first bevel wheel 2.3 and the first hollow wheel 2.4 is designed permeable for liquid via several first passage openings 2.5 for arranged distributed over the circumference. Moreover, the connection housing 2.1 can be designed in two further variants (2.1*, Figures 3a to 3c; 2.1**, Figures 4 to 9).
The nozzle head housing 3 is designed as a hollow body, which is elongated in a design of the first type on the side of the connection housing 2.1 in a housing shaft 3a connected permanently and preferably as one piece with the nozzle head housing 3. This housing shaft 3a forms in the inside a first housing opening 3b, via which a first access to the interior of the nozzle head housing 3 exists. On the side of the nozzle head 4, the nozzle head housing 3 has a second housing opening 3c, via which a second access to the interior of the nozzle head housing 3 is given. The preferably one-piece unit consisting of the fastening shaft 2.2, the first bevel wheel 2.3 and the first internally toothed hollow wheel 2.4 is inserted into the nozzle head housing 3 via the second housing opening 3c and connected in form- and/or force-fitting manner, preferably screwed through the first housing opening 3b with the connection housing 2.1 introduced from above.
Between a recess comprising the first housing opening 3b in the area of the transition between the nozzle head housing 3 and its housing shaft 3a (not shown) on the nozzle head housing 3 and the first bevel wheel 2.3, a first bearing 11.1 preferably designed as a ball bearing is provided (Figure 1b), which serves the rotatable mounting of the nozzle head housing 3 on the connection housing 2.1 around the first rotational axis I, which progresses coaxially to the connection housing 2.1 and its feed line 2.1d. A second bearing position for the nozzle head housing 3 is provided a bit further axially on the outside of the first internally toothed hollow wheel 2.4 in the form of a bearing (not shown).
The housing shaft 3a surrounds with its first housing opening 3b the connection housing 2.1. It is respectively rotatably mounted on the connection housing 2.1 on the end side via a first slide ring 16.a of a first slide bearing 16 or respectively a second slide ring 17a of a second slide bearing 17 around the first rotational axis I and forms an annular space 13 in the axial direction between these two slide bearings 16, 17 and in the radial direction between itself and the connection housing 2.1, which is connected with the infeed opening 2.1a via branching channels 2.1b in the wall of the connection housing 2.1. Advantageously, the slide rings 16a, 17a should thereby be measured radially such that a minimal liquid passage takes place through the bearing gap respectively given at them according to the effective pressure differences in terms of a self-cleaning of these area. This liquid transport also continues over the first bearing 11.1 into the interior of the nozzle head housing 3 via the first slide bearing 16.
The second housing opening 3c in the nozzle head housing 3 is oriented coaxially to the second rotational axis II, which preferably crosses the first rotational axis I and progresses perpendicular to it. A second bevel wheel 5 is inserted into the nozzle head housing 3 via the second housing opening 3c. The second bevel wheel 5 is arranged coaxially to the second rotational axis II and it meshes with the first bevel wheel 2.3. The mounting of the second bevel wheel 5 takes place on the left side via a second bearing 11.11 preferably designed as a ball bearing, which is held on one side by the second bevel wheel 5 and on the other side by a fastening ring (not shown) screwed into the second housing opening 3c, and on the right side via a slide ring (not shown), which is arranged between the aforementioned fastening ring and the nozzle head 4. The second bevel wheel 5 ends on the inside in a centric hub 5a, which is screwed with the nozzle head 4.
In an axial continuation of the infeed opening 2.1a, a turbine 6 is arranged within the connection housing 2.1 and the one-piece unit connecting to it, consisting of the fastening shaft 2.2, the first bevel wheel 2.3 and the transition area to the first internally toothed hollow wheel 2.4, and coaxially to the first rotational axis I, which is driven by the flow energy of the intake flow of the cleaning fluid R flowing to the receptacle cleaning device 1 via the infeed opening 2.1a. The turbine 6 consists, as seen in the direction of flow, of a guide vane 6b permanently connected with the fixed housing body 2 and a rotor wheel 6a with several rotor blades. The rotor wheel 6a is fastened on a turbine shaft 7, which is mounted on one side in the area of the guide vane 6b in a fifth bearing 12.3 and on the other side in the area of a second internally toothed hollow wheel 10, which is permanently arranged below the first internally toothed hollow wheel 2.4 within the nozzle head housing 3, via a third bearing 12.1.
The turbine shaft 7 carries on its end facing away from the guide vane 6b a toothed wheel designed as a sun wheel 8 (Figure 1c), which meshes with a planetary gear 9 consisting at least of two planetary wheels. The planetary wheels are respectively provided over their entire axial extension with a single respectively continuous toothing, wherein each planetary wheel engages with the one end into the first internally toothed hollow wheel 2.4 permanently connected with the connection housing 2.1 and with the other end into the second internally toothed hollow wheel 10 permanently connected with the nozzle head housing 3. The two planetary wheels rotating on the inside around the sun wheel 8 and on the outside in the hollow wheels 2.4 and 10 are, as seen in the axial direction, rotatably mounted on one side in the area of the third bearing 12.1 and on the other side on the turbine shaft 7 via a fourth bearing 12.2.
The mode of action of this type of receptacle cleaning device 1, which obtains its drive energy via the turbine 6 supplied by the flow energy of the cleaning fluid, is sufficiently known from the state of the art (e.g. EP 1 062 049 B1). Due to the difference of the number of teeth for the first internally toothed hollow wheel 2.4 and the second internally toothed hollow wheel 10, which must be at least one tooth, each full revolution of the planetary wheels around the sun wheel 8 leads to a relative displacement of the hollow wheels 2.4 and 10 in their circumferential direction with respect to the first rotational axis I. This relative ro tational displacement prompts the rotationally moveable second bevel wheel 5 to twist against the stationary first bevel wheel 2.3 (unwinding movement) and thus causes a rotation of the nozzle head 4 with respect to the nozzle head housing 3 around the second rotational axis II with a second rotational speed nn, whereby a rotation of the nozzle head housing 3 with respect to the fixed housing body 2 around the first rotational axis I is simultaneously generated with a first rotational speed ni.
In the housing shaft 3a, a first receiving hole 3f is provided, which serves to receive at least a first independent auxiliary nozzle 30. The latter can be fastened in the receiving hole 3f in a surface-connected (e.g. through welding) or in a form- and/or force-fitting manner (e.g. through screwing or through pressing in). The exemplary embodiment shows the first auxiliary nozzle 30 in the form of a flat-spray nozzle. The latter is connected with the infeed opening 2.1a via the annular space 13 and the branching channels 2.1b and it delivers a second partial flow R2 fed out of the intake flow of the cleaning fluid R to the shell surface of the receptacle. Since the housing shaft 3a is permanently connected with the nozzle head housing 3, the first auxiliary nozzle 30 inevitably rotates synchronously with the nozzle head housing 3 around the first rotational axis I. The first auxiliary nozzle 30 is thereby arranged on the circumference of the housing shaft 3a (see Figure 1d) such that a crossing of the second spray jets of the second partial flow R2 exiting the first auxiliary nozzle 30 and a first partial flow R1 exiting the nozzles 19 at nozzle head 4, which generates first spray jets, is safely avoided. If two auxiliary nozzles 30 are to be provided on the housing shaft 3a, they are advantageously arranged diametrically opposed to each other, wherein their symmetrical axis are preferably oriented by 90 degrees vis-a-vis the second rotational axis II.
In one design of the second type, the annular space 13 is delimited with respect 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 hole 14a. The first nozzle housing 14 is rotatably mounted on the connection housing 2.1, wherein the mounting takes place on its bottom end via a third slide ring 18a of a third slide bearing 18, and it is connected in a form-fitting driving connection with the nozzle head housing 3. In the exemplary embodiment, this driving connection is realized such that the first nozzle housing 14 has on its bottom end a first driving recess 14b (Figures 2b, 2c), into which a driving pin 20 engaging on the upper end of the nozzle head housing 3 engages in a formfitting manner. The design of the second type otherwise corresponds with respect to the further structure and mode of action to the design of the first type.
The design of the second type shown above experiences a modification in that the nozzle housing is now designed in a round-bodied manner in the radial direction and thus more compact in the axial direction and thereby takes on the shape of a second nozzle housing 15 (Figures 3a, 3b and 3c). This shape leads to the modified connection housing 2.1* correspondingly more compact in the axial direction and modified branching channels 2.1b* correspondingly axially displaced and it now permits the design of a first auxiliary nozzle 15a* of the integrated form and, if applicable, a second auxiliary nozzle 15b* of the integrated form respectively through the wall of the second nozzle housing 15 itself (Figures 3a, 3c). The second nozzle housing 15 is in turn connected in a formfitting driving connection with the nozzle head housing 3. This driving connection is realized according to that on the first nozzle housing 14, wherein the second nozzle housing 15 has a second driving recess 15c on its bottom end (Figure 3b), into which the driving pin 20 engaging on the upper end of the nozzle head housing 3 engages in a form-fitting manner.
The nozzle head housing 3 can also have at least one additional auxiliary nozzle 30.1, 30.2, 3d*, 3e* (Figure 1b), wherein it can 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*. Two integrated auxiliary nozzles 3d*, 3e* are provided in the exemplary embodiment. These are supplied from a fourth partial flow R2.1 and a fifth partial flow R2.2, which are also generated, in addition to the first partial flow R1, from the differential flow of cleaning fluid R - R2 supplied to the turbine 6. The auxiliary nozzles 30.1,30.2, 3d*, 3e* are thereby generally aligned such that the spray jets delivered by them exit onto the inner shell surface of the receptacle. In the exemplary embodiment, the integrated second auxiliary nozzle 3d* is arranged in the transition area of the nozzle head housing 3 between its shell area and its front-side periphery, wherein this is the preferred arrangement position, since the most beneficial geometric conditions exist here.
Moreover, each point on the nozzle head housing 3 is suitable for the arrangement of the auxiliary nozzles 30.1, 30.2, 3d*, 3e*, which have free access to the interior of the nozzle head housing 3, and namely with respect to its axially extension area along the first rotational axis I. As shown by the exemplary embodiment with respect to the integrated third auxiliary nozzle 3e*, another possible point is the shell area of the nozzle head housing 3 between the first bevel wheel 2.3 and the first internally toothed hollow wheel 2.4. Furthermore, the area of the second internally toothed hollow wheel 10 is conditionally suitable for this.
The alignment of the respective auxiliary nozzle 30, 30.1, 30.2, 15a*, 15b*, 3d*, 3e* in the area of the housing shaft 3a or of the nozzle housing 14, 15 or of the nozzle head housing 3 can take place such that the line of action of the symmetrical axis of the respective auxiliary nozzle crosses the first rotational axis I. But the corresponding line of action of the symmetrical axis can also have a radial distance from the first rotational axis I. It is decisive in the case of the arrangement and alignment of the auxiliary nozzles 30, 30.1, 30.2, 15a*, 15b*, 3d*, 3e* that they deliver their respective cleaning fluid R2, R2.1, R2.2 in every case to the shell surface of the receptacle.
The auxiliary 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 the extension surface of the flat-spray progresses mainly parallel to the first rotational axis I in a preferred embodiment. Flat-spray nozzles arranged in this manner on the upper area of the nozzle head housing 3 or respectively on the housing shaft 3a or on the nozzle housing 14, 15 are suitable, in addition to the shell area of the receptacle, to also capture its upper floor to the greatest possible extent.
The independent auxiliary nozzle 30, 30.1, 30.2 is, as Figures 1b, 1d, 1e, 2b and 2c show, fastened in a surface-connected manner (e.g. through welding) in the nozzle head housing 3 or in form- and/or force-fitting manner (e.g. through screwing or through pressing in). But the auxiliary nozzle of the integrated form 15a*, 15b* or respectively the integrated auxiliary nozzle 3d* 3e* can also be formed respectively by the wall of the second nozzle housing 15 or respectively of the nozzle head housing 3 or, if applicable, of the housing shaft 3a itself. In this case, the latter are to be bored open according to the necessary nozzle size and an additional milling is to be performed at the outlet side of the spray jet if a flat-spray nozzle is to be provided.
From the intake flow of the cleaning fluid R, which flows to the interior of the connection housing 2.1,2.1* via the infeed opening 2.1a (Figures 1a to 3c), the second partial flow R2 is branched via the branching channels 2.1b, 2.1b*, which is delivered via the first independent auxiliary nozzle 30 or respectively the auxiliary nozzles of the integrated form 15a*, 15b* to the shell surface of the receptacle in the form of a so-called flush cleaning rotating around the first rotational axis I. The differential flow of cleaning fluid R - R2 (Figures 1a, 1b) flows entirely through the guide vane 6b and the rotor wheel 6a connecting to it, in order to split starting from here, wherein a partial flow flows to the nozzle head 4 via the first passage openings 2.5 arranged above the planetary gear 9 and then via second passage openings 5b in the second bevel wheel 5 and another partial flow first flows through the planetary gear 9, in order to make its way from there into the nozzle head 4 partially via the second passage openings 5b. The first partial flow R1 exits overall via the nozzles 19 of the nozzle head 4, wherein the nozzles 19 execute a superimposed spatial rotational movement and the entire interior surface of the receptacle is thereby captured orbitally after a certain period of time.
Another partial flow makes its way into the auxiliary nozzle 3e*, 30.2 via the first passage openings 2.5 above the planetary gear 9 as the fifth partial flow R2.2. A certain portion as the fourth partial flow R2.1 makes its way into the auxiliary nozzle 3d*, 30.1 out of the partial flow penetrating the planetary gear 9.
The cleaning fluid flowing 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) (Figures Id, 1e, 2c and 3c). The partial flow R1 makes its way into the nozzles 19 in the nozzle head 4, wherein all nozzles 19 together deliver the first partial flow R1 into the receptacle to be cleaned. The third partial flow R3 makes its way to a spraying device 4a designed as a nozzle, which is designed on the outer edge of the nozzle head 4, and supplies in a rotating manner the nozzle head housing 3 for one as a result of the rotation of the nozzle head 4 around the second rotational axis II (second rotational speed nM). On the other hand, the nozzle head housing 3 executes a rotation around the first rotational axis I (first rotational speed ni), so that the third partial flow R3 also continuously supplies 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 auxiliary nozzles 30, 30.1, 30.2, 15a*, 15b*, 3d*, 3e* rotate around the first rotational axis I and flush the shell surface of the receptacle continuously, whereby the object according to the invention is solved.
The main features of the receptacle cleaning device 1 in Figures 4 to 7 and Figure 9 were already described above. Thus, we will only refer below to special features that either were not shown in the figures of the drawing described up until now or that concern in particular the self-cleaning of the receptacle cleaning device 1.
In the embodiment shown in Figure 4, the nozzle head housing 3 ends shortly above the first slide bearing 16, which functions as a radial bearing. Besides the first bearing 11.1 preferably designed as a ball bearing, which acts like an axial bearing, a second bearing position is provided for the radial mounting of the nozzle head housing 3, which is arranged a bit further axially 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 annularly closed slide bearing, which consists of a preferably metallic 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 surrounded by the nozzle head housing 3 except for this housing opening area and can thus provide a stable mounting on the first internally toothed hollow wheel 2.4 abutting into the interior of the nozzle head housing.
Between the connection housing of the second type 2.1** in connection with the fastening shaft 2.2 and the first bevel wheel 2.3 on one side and the nozzle head housing 3 in this area on the other side, a first circumferential annular gap 32 is designed, which connects the interior of the nozzle head housing 3 via the first bearing 11.1 with the surroundings of the receptacle cleaning device 1. In the progression of this first circumferential annular gap 32, the first slide ring 16a of the first slide bearing 16 is arranged in front of its outlet into the surroundings of the receptacle cleaning device 1.
The mounting of the second bevel wheel 5 takes place via the second bearing 11.11 preferably designed as a ball bearing, which is held on one side by the second bevel wheel 5 and on the other side by a fastening ring 21 screwed into the second housing opening 3c.
Between the nozzle head 4 on one side and the fastening ring 21 in connection with an edge of the nozzle head housing 3 (not denominated) comprising the second housing opening 3c on the other side, a second circumferential annular gap 33 is designed, which connects the interior of the nozzle head housing 3 with the surroundings of the receptacle cleaning device 1. In the progression of this second circumferential annular gap 33, a fourth slide ring 23a is arranged in front of its outlet into the surroundings of the receptacle cleaning device 1, which forms a fourth slide bearing 23 in the nozzle head housing 3 in connection with the fastening ring 21 on one side and the nozzle head 4 on the other side with respect to its common second rotational axis II. The fourth slide bea ring 23 realizes the second bearing position for the second bevel wheel 5 in connection with the nozzle head 4 within the nozzle head housing 3.
The second internally tooth hollow wheel 10 is inserted into the interior of the nozzle head housing 3 in the course of the installation of the receptacle cleaning device 1 via the second housing opening 3c and fixed in an undisplaceable manner in its end position via 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 provided respectively over their entire axial extension with a single respectively integrated second toothing, wherein each planetary wheel 9.1, 9.2 engages with the one end into the first internally toothed hollow wheel 2.4 permanently connected with the connection housing of the second type 2.1** and with the other end into the second internally toothed hollow wheel 10 that is coaxial to the internally toothed hollow wheel 2.4 and permanently connected with the nozzle head housing 3. The sun wheel 8 with the first toothing has number of teeth z8 = 6, while the two planetary wheels 9.1 and 9.2 designed identically are respectively provided with the second toothing (number of teeth zg.-i = 22). The first internally toothed hollow wheel 2.4 has a third toothing (number of teeth Z2.4 = 50) and the second internally toothed hollow wheel 10 has a fourth toothing (number of teeth zi0 = 52).
The cleaning fluid R flowing via the infeed opening 2.1a to the interior of the connection housing of the second type 2.1** flows in its entirety through the guide vane 6b with the rotor blades 6b* and the connecting rotor wheel 6a with the rotor blades 6a* in order to split from here, wherein a partial flow flows directly to the nozzle head 4 via the passage openings 2.5 arranged above the planetary gear 9 and another partial flow first flows through the planetary gear in order to make its way into the nozzle head 4 from there also via the passage openings 2.5 in the second bevel wheel 5. 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 11.11 of the nozzle head are thereby supplied from these partial flows of the 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 have a permeability for cleaning fluid r4 (first slide bearing leakage) determined and delimited by the respective bearing play or respectively r5 (second slide bearing leakage), which respectively suffice to clean these areas sufficiently. The first bearing 11.1 located upstream from the first circumferential annular gap thereby experiences a sufficient supply with cleaning fluid so that a good self-cleaning also takes place in this area.
That cleaning fluid R or respectively R - R2 (the differential flow R - R2 is present when the second partial flow R2 is branched off upstream of the turbine 6), which flows through the passage openings 5b in the second bevel wheel 5 (see Figure 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 makes its way into an infeed hole 4c in the nozzle head 4 via a connection hole 4d, wherein in the exemplary embodiment four of these connection and infeed holes 4d, 4c are provided and each of the infeed holes 4c on the end opens into the associated nozzle 19 (also see Figure 5). All nozzles 19 deliver together the first partial flow R1 into the receptacle to be cleaned. The third partial flow R3 makes its way, as seen in the direction of flow, into an independent infeed channel 4b (Figures 4 and 7) before reaching the fourth slide bearing 23, via which the spraying device 4a designed as a nozzle is supplied, which is designed entirely in the nozzle head 4.
The first partial flow R1 (first spray jets), which results from the cleaning fluid R (main flow) entering the receptacle cleaning device 1 via the infeed opening 2.1a less all partial flows branched off up to the nozzles 19, thus arrives at the nozzles 19 of the nozzle head 4, which are provided for the actual cleaning of the receptacle. The third partial flow R3 exiting via the spraying device 4a are thereby regular, distinctive third spray jets, which supply the nozzle head housing 3 circumferentially for one as a result of the rotation of the nozzle head 4 around the second rotational axis II (second rotational speed nu) (see in particular Figures 5, 6 and 9). On the other hand, the nozzle head housing 3 executes a rotation around a first rotational axis I (rotational speed ni) so that the third partial flow R3 continues to supply the surface of the connection housing of the second type 2.1** or respectively of the housing shaft 3a (Figures 1a to 1e) or of the nozzle housing 14, 15 above the nozzle head housing 3 (Figures 2a to 3c) with cleaning fluid.
The first and the second slide bearing leakage r4, r5 generate no distinctive spray jets, but rather a moderate self-cleaning from inside to outside is ensured here, while the cleaning up of contaminants discharged if applicable from the circumferential annular gaps 32 and 33 or fed to them from the outside takes places by the third partial flow R3. The mode of action of the spraying device 4a designed as a nozzle is made particularly clear by the representations in Figures 5, 6 and 9. In particular, the representation according to Figure 9 shows that the third partial flow R3 exiting the spraying device 4a includes the outlet area of the second circumferential annular gap 33.
In order to ensure an optimal design of the first spraying jets of the first partial flow R1 exiting from the nozzles 19, the respective infeed hole 4c to the associated nozzle 19 is designed with the largest possible length ΔΙ (Figure 5), as can be seen in the drawing on a nozzle 19. This succeeds due to the fact that the longitudinal axis of the infeed hole 4c forms the tangent to a circle K concentric to the second rotational axis II with radius a. This radius a is designed as large as possible, wherein it is ensured that the respective connection hole 4d does not engage in the adjacent infeed hole 4c or respectively the adjacent nozzle 19.
In view of a sufficient self-cleaning of the receptacle cleaning device 1, an area generally difficult to capture on the nozzle head housing 3 results on the outside, which faces away from the nozzle head 4, if one does not want to install a separate nozzle in the upper area of the connection housing 2.1**, 2.1, 2.1*, as is the case for example in the receptacle cleaning device according to EP 1 062 049 B1, which would in turn represent a technical cleaning problem.
In order to capture the contemplated problematic surface area of the nozzle head housing 3 with cleaning fluid with the third partial flow R3 exiting the spraying device 4a, the invention provides that the outside of the nozzle head housing 3 (see in particular Figures 5, 6 and 9), on both sides of and symmetrical to a plane progressing through the first and the second rotational axis I, II, is provided respectively with a slightly concave recess 3*, which respectively has oppositely bent transitions to the neighboring outsides of the nozzle head housing 3. In those phases of the cleaning process, in which the third partial flow R3 directly flushes respectively the concave recess 3*, the cleaning fluid hitting there, in particular when it hits the outer areas of the concave recess 3*, is prompted by this special shape of the surface, to rather flow to the deepest point of the concave recess 3* in order to flow from there to the area of the surface of the nozzle head housing 3 located far from the nozzle head as a liquid film (see in particular Figure 6) adhering to the surface. A second embodiment of the receptacle cleaning device 1 according to the invention (Figure 8) is characterized vis-å-vis the first embodiment according to Figure 4 in that the first circumferential annular gap 32, in the area of its exit into the surroundings of the actuating device 1, is not oriented parallel to the first rotational axis I, as is the case in Figure 4, but rather has an orientation at least perpendicular to the first rotational axis I or perhaps even tilted downwards slightly. The first slide bearing leakage r4 can thereby flow to the outside in the radial direction without interference from the first circumferential annular gap 32. Furthermore, in the corresponding phases of the circumferential procedure of the nozzle head 4, the third partial flow 4 exiting the spraying device 4a hits the first circumferential annular gap 32 directly so that a particularly effective cleaning of contaminants can take place here.
