DESCRIPTION

Container cleaning device 5 Technical scope

The invention relates to a container cleaning device that can be introduced into an opening of a container and having a housing body having a connection housing attached to a supply conduit for cleaning liquid and arranged in a non-rotating manner. with respect to the container, as well as a rotating nozzle head housing with respect to the latter about a first axis of rotation, with at least one nozzle head disposed in the nozzle head housing rotatably about a second axis of rotation and provided with at least one nozzle, distributing the nozzle (s) during use a first partial current fed from the affluent stream of the cleaning liquid, the rotation movement being generated around the axis of rotation with means of actuation arranged in or outside the container cleaning device and, if necessary, also outside the container, and operated by external energy.

State of the art

A container cleaning device of the generic type in which the actuation means are arranged outside the container cleaning device and operated by external energy is described in the document.

DE10024950C1.

The container cleaning device according to EP1062049B1 has, in the upper part of the stationary, non-rotating housing part, additionally a spray nozzle. The spray direction of this additional spray nozzle, with respect to the represented position of the device, is oriented downwards towards the orbital development nozzle arrangement, to produce the necessary self-cleaning. The cleaning of the container itself is improved or intensified by this additional spray nozzle.

The mutual sealing of the moving parts with respect to each other of the known device according to document 30 EP1062049B1 is carried out to a greater extent in such a way that the exit of cleaning liquid from the interior space of the container cleaning device to its surroundings is prevented by means of elements adequate sealing. The separating joints of the movable parts with respect to each other represent critical problem areas for cleaning which, by the aforementioned spray nozzle, can only be subjected to insufficient cleaning.

A self-cleaning container cleaning device, both inside and out, was disclosed by document EP0560778B1. There is provided a spraying device that with its nozzle head rotates around the second axis of rotation and is made in the form of a screen that covers a part of the circumferential annular gap that exists in the nozzle head and that deflects the liquid that leaves towards the screen, such that it cleans the outer surfaces of the container cleaning device housing. This spray nozzle 40 that also serves to self-clean the device cannot improve the cleaning of the container.

Since between the parts of the container cleaning device, movable relative to each other, according to EP0560778B1, circumferential interstices of relatively large, liquid permeable dimensions of the flow of cleaning liquid flowing through the device are arranged Two relatively large partial currents are derived through these circumferential annular interstices, which are then no longer available to the nozzles in the nozzle housing for their function itself, namely the cleaning of the container. On the one hand, it is difficult to limit the amount of partial current leaving the entire contour of the corresponding circumferential gap to the necessary extent and, on the other hand, its size depends substantially on the respective pressure conditions existing in the interior space of the container cleaning device that may be subject to temporary fluctuations.

A spraying device that rotates with the nozzle head, according to EP0560778B1, which is made in the form of a screen that covers a part of the circumferential interstitium existing in the nozzle head and that deflects the liquid that flows into the screen, from such that it cleans the outer surfaces of the housing of the container cleaning device, it is problematic as regards its feeding of cleaning liquid, because this feeding in turn depends in a special way on the conditions of pressure and circulation in the interstitium assigned circumferential.

In the two aforementioned container cleaning devices (documents EP1062049B1; EP0560778B1), the nozzles arranged in the corresponding nozzle head perform a spatial rotation movement superimposed around two rotation axes, whereby the sprayed jets coming out of said nozzles display a particularly intensive mechanical cleaning effect due to their orbital kinematics on the inner surface of the container that has to be cleaned. Depending on the ratio of the number of revolutions made around the two axes of rotation, a typical spray pattern results in the interior surface of the container that is produced again at certain time intervals. In this regard, it has been shown that the intense mechanical cleaning effect of the spray jets leaving the orbital development spray nozzles looses the dirt on the surface of the container well, but often the amount of distributed cleaning liquid does not 10 is enough to remove by washing loose dirt quickly from the wall of the container and lead it to the exit of the container. Therefore, to ensure a complete transport of loose dirt at the exit of the container, the container cleaning device frequently remains in service for longer than would be necessary in principle with a view to the dirt to be dissolved and released. .

In addition, container cleaning devices are known in which a nozzle head provided with at least one nozzle rotates around a single axis of rotation and during this, the inner wall of the container always rotates in a rotary manner at the same points. The rotation movement of the nozzle head around the corresponding axis of rotation can be generated by actuating means arranged outside the container cleaning device and also outside the container and driven by external energy (for example, an electric motor) (document 20 DE1869413U) . In document DE2645401C2 a container cleaning device with the kinematic characteristics described above is described, the actuation means of which are disposed outside the container and actuated by the circulating energy of the flow of cleaning liquid flowing into the cleaning device of containers

Finally, from DE10208237C1 a container cleaning device with the kinematic characteristics in question was disclosed, in which the actuating means for generating the turning movement of the nozzle head are arranged completely within the cleaning device of containers and powered by the circulating energy of the flow of cleaning liquid flowing into the device

container cleaning.

30

These three known container cleaning devices, selected above as examples (documents DE1869413U; DE2645401C2; DE10208237C1) distribute sufficient amounts of cleaning liquid to the inner wall of the container, but the cleaning effect of nozzles rotating around a single axis of rotation and whose spray jets always affect the same points of the container is generally unsatisfactory with a view to efficient and economical cleaning of the entire container.

The present invention aims to improve the container cleaning device of the generic type in such a way that it additionally displays an intense cleaning effect that reaches all areas of the container in less time, the container cleaning device being performed extraordinarily. compact, 40 presenting optimal self-cleaning characteristics inside and out.

Summary of the Invention

This objective is achieved by a container cleaning device with the characteristics of claim 1. Advantageous embodiments of the proposed container cleaning device are subject to the dependent claims.

The idea of a decisive solution according to the invention is that in the nozzle head housing which rotates around the first axis of rotation there is at least one additional nozzle that is used exclusively for cleaning containers. This additional nozzle thus differs decisively from known solutions in this regard (for example, document EP1062049B1) in which the additional nozzle is stationary and exclusively performs the self-cleaning (external cleaning) of the container cleaning device.

Since the additional nozzle according to the invention rotates only around the first axis of rotation and during this 55 distributes a second partial current to the inner envelope surface of the container, which is fed from the tributary current that flows into the container cleaning device, this Enveloping surface is widely dripped with cleaning liquid at shorter time intervals than is the case with only the nozzles moved orbitally around the two axes of rotation. The cleaning by jets distributed only around an axis of rotation is drained as a liquid film through the wrapping surface of the container contributing

this way with special effectiveness to the forced elimination and the accelerated evacuation of the released dirt.

The respective drive means operated by external energy can be arranged inside (document DE10208237C1) in or outside the container cleaning device, being provided in the last form of mentioned embodiment also an arrangement outside the container (documents DE1869413U; DE2645401C2).

The derivation of the second tributary stream is carried out with a constructive configuration of a first type, especially advantageous and simple, if, as provided, the second tributary stream is supplied through at least one branch channel in the wall of the connection housing a an annular chamber that wraps the connection housing 10 on the outside and that receives its delimitation from the environment by a carcass rod made in the nozzle head housing and rotatably supported on the connection housing and which flows into the additional nozzle arranged inside the housing rod. The configuration of the first type is especially recommended when the so-called jet cleaning distributed around an axis of rotation by the additional nozzle according to the invention is desirable or necessary beforehand and additionally to the orbital cleaning must be provided for the nozzles in the nozzle. nozzle housing.

A corresponding configuration of a second type according to the invention provides that the second partial current is supplied through at least one bypass channel in the wall of the connection housing to an annular chamber that envelops the connection housing, which receives its delimitation in front of the environment by a first or a second connection housing 20 and which flows into the additional nozzle disposed within the nozzle housing, the nozzle housing being rotatably supported on the connection housing and connected by drag connection with the nozzle head housing. The configuration of the second type is especially recommended when the so-called jet cleaning by the additional nozzle according to the invention is optionally desired or necessary only during the course of cleaning the container, so that a simple retrofitting of the additional nozzle is guaranteed. .

In the configurations of the first or second type, described above, the pressure and circulation conditions of the first partial current are not significantly influenced, since in this respect, the location of the derivation of the second partial current and their position with respect to the drive means play only a subordinate role.

The configurations of the first or second type, described above, are substantially without influence on the pressure and circulation conditions in the area of the first tributary current towards the nozzles in the nozzle housing, if the second partial current is derived in its all before the actuation means 35 disposed within the container cleaning device. This configuration constitutes the most advantageous and preferable solution within the framework of the Invention.

An advantageous embodiment of the container cleaning device according to the invention provides in the respective combination with the configuration of the first or second type that the nozzle head housing 40 additionally has at least one additional nozzle, generally providing a maximum of two These additional nozzles. According to another proposal, the respective additional nozzle is arranged in one of the possible points of the nozzle head housing that have free access to the interior space of the nozzle head housing, in particular, with respect to the axial extension zone of this along the first axis of rotation. As possible points, the surrounding area of the nozzle head housing and / or preferably the transition zone of the nozzle head housing between the surrounding area of the nozzle and its frontal delimitation surface are considered here.

The orientation of the respective additional nozzle can also be carried out in a manner designed so that the line of action of its axis of symmetry crosses the first axis of rotation. But the line of action of the axis of symmetry 50 can also have a radial distance from the first axis of rotation. For the arrangement and orientation of the additional nozzles it is decisive that in any case they bring their cleaning liquid to the enclosure surface of the container.

According to another proposal, the additional nozzles are advantageously made as flat jet nozzles that produce a fan-shaped flat jet, the extension surface of the flat jet extending substantially parallel to the first in a preferable embodiment. axis of rotation.

The realization and arrangement of the additional nozzle are especially simple if, according to another proposal, it is formed by the wall of the nozzle head housing itself. For such an embodiment, namely an additional nozzle of the Integrated form, the second nozzle housing made especially suitable is

bulging. Another embodiment of this type, namely an additional integrated nozzle, can be arranged in a particularly simple way, in the transition zone of the nozzle head housing, between the surrounding area of the nozzle and its frontal delimitation surface, and that there are especially favorable geometric conditions there.

5

Another proposal envisages making the additional nozzle as an independent component (independent additional nozzle) and fixing it by joining materials, for example by welding, inside the nozzle head housing opened by drill. In addition, in this regard it is envisaged to arrange the additional nozzle in the form of the independent component by geometric and / or forced connection in the nozzle head housing. It is worth mentioning, for example, screwing or pressure insertion. Solutions of this type are preferable to the fixing by joining of materials or the realization by the wall of the nozzle head housing itself, if the cleaning procedures can be optimized only during the operation of the container cleaning device and if so it is required, if necessary experimenting, the repeated replacement of different additional nozzles.

15 A container cleaning device made in a particularly compact manner is achieved if it presents in a known manner in itself a planetary gear driven by the external energy which, in combination with a bevel gear, produces the rotational movement around the corresponding axis of rotation.

If, according to another proposal, in the container cleaning device, the gear is arranged completely in the zone 20 of the space that is delimited by the two conical wheels of the bevel gear with its corresponding outer diameter and in the direction towards their respective axes of rotation and which forms an intersection of common spatial assemblies of these delimited spaces, is the most compact spatial form imaginable of the container cleaning device in question, since by this fully integrated arrangement the maximum possible extension of the container cleaning device is achieved. In none of these container cleaning devices that have been disclosed so far, the entire planetary gear has been fully integrated into the area defined above within the bevel gear.

If, as provided in an advantageous embodiment, the first hollow wheel is arranged a little further from the first conical wheel, seen in the direction of the first axis of rotation, and if in the junction zone between the first wheel Conical and the first hollow wheel are provided several first through holes arranged in a distributed manner by the contour, a large part of the cleaning liquid that passes through the container cleaning device can already be evacuated behind the first conical wheel to the nozzle head, seen in the direction of movement, without having to first pass through at least part of the planetary gear, as is the case in the container cleaning device according to EP0560778B1. In the 35-vessel cleaning device according to EP1062049B1, the planetary gear must be completely traversed by the complete cleaning liquid stream, so that there is the maximum possible resistance to circulation here. By disposing the planetary gear according to the invention, the losses of circulation of the cleaning liquid during the passage through the container cleaning device are reduced, and the partial current of cleaning liquid that still circulates through the planetary gear ensures sufficient cleaning of the same.

40

The first hollow wheel, the first conical wheel and a fixing rod that forms the continuation of the latter on its side opposite the hollow wheel conveniently form a unit in one piece that according to another proposal is preferably attached to the connection housing by geometric and / or forced connection, preferably by threaded connection. A single-piece unit of this type can be manufactured as a casting part or as a combined turned and milled part and in this embodiment it greatly facilitates the structure and also the assembly of the container cleaning device.

An economic handling of the cleaning liquid for the self-cleaning of the two circular annular interstices is achieved without questioning the quality of this self-cleaning, if according to another embodiment of the container cleaning device according to the invention, the liquid permeability The cleaning of said circumferential annular gap is limited to the extent that a sliding support of parts of the cleaning device of paired containers between them, rotatably arranged relative to each other, is required or allows. For this purpose, it is provided that in the course of a first circumferential annular gap between the connection housing and the nozzle head housing and a second circumferential annular gap between the nozzle head housing 55 and the nozzle head, respectively before The exit of said circumferential annular interstices to the environment of the container cleaning device, respectively, is a sliding ring that forms a first sliding bearing for the two housings with respect to the first common axis of rotation of these and a second sliding bearing. for the pieces with respect to the second axis of rotation of these.

The sliding ring of a sliding bearing forms in a known manner with the adjacent bearing interstices necessary to allow a sliding movement forming a liquid film (in this case it is a cleaning liquid). The amount of this cleaning liquid that necessarily passes through the sliding bearing is delimited by the relatively narrow bearing interstices, but it is sufficient to subject this critical area to self-cleaning. This measure avoids an unnecessarily large derivation of partial streams of cleaning liquid through the circumferential annular gap without questioning its self-cleaning.

According to another proposal, the cleaning of the circumferential annular gap in the area between the corresponding sliding bearing 10 and the environment of the container cleaning device is ensured by the spraying device rotating with the nozzle head. This is made as a nozzle that is completely made inside the nozzle head. The feeding of this nozzle with a second partial current of the cleaning liquid is carried out through an independent supply channel disposed within the nozzle head.

15 A simple and very compact planetary gear is made according to another proposal in such a way that each planetary wheel is provided along its total axial extension of a single continuous second toothed. It is dispensed with providing the corresponding planetary wheel of two different teeth, that is, two different numbers of teeth and different modules. A different teeth in this respect is provided in document EP0560778B1; EP1062049B1 discloses only the numbers of equal teeth with respect to the 20 gear of the corresponding planetary wheel. The respective gear of the planetary wheel meshes with one of its ends in a first hollow wheel with internal teeth and with its other end in a second hollow wheel with internal teeth.

By integrating the planetary gear in the area of the bevel gear, the first hollow wheel with internal toothing is also in this zone 25, fixedly attached to the stationary connection housing. This first hollow wheel that practically peeks into this area allows an additional support of the nozzle head housing on its outer side. For this purpose, in the area of a second housing opening made in the nozzle head housing and arranged coaxially with respect to the second axis of rotation, a sixth bearing made as an annularly closed sliding bearing is provided, which serves to The additional support of the first hollow wheel inside the nozzle head housing around the first axis of rotation. The annularly closed embodiment of the sliding bearing which conveniently consists of a metal support ring and a sliding ring, gives this bearing sufficient stability, although in this area, due to the presence of the second housing opening , there is no complete beading for the nozzle head housing to be supported.

35

To ensure optimum formation of jets of the partial stream of cleaning liquid leaving the nozzle in the nozzle head, if possible, another embodiment of the proposed container cleaning device provides that each nozzle in the nozzle head is joined together with an inflow hole arranged in the latter, the corresponding longitudinal axis of the inflow drill forming the tangent in a concentric circle 40 with respect to the second axis of rotation, with a given radius, and the latter is sized such that the inflow drill forms a maximum possible length in the nozzle head.

The cleaning of the outer side of the nozzle head housing by means of the nozzle carried out independently in the nozzle head and also fed independently through a supply channel is improved because said outer side towards which the nozzle is oriented third rotary partial current leaving the nozzle is provided, on both sides and symmetrically with respect to a plane that runs along the first and second axis of rotation, respectively with a slightly concave cavity having transitions, curved respectively in opposite directions, towards the adjacent outer sides of the nozzle head housing. By the concave cavity, at least a part of the cleaning liquid applied on the outer side in this area 50 accumulates in the deepest area of the cavity to arrive from here as a film of liquid more or less adhered to the surface, up to the rear end of the container cleaning device housing, seen in the direction of movement. Without the realization of such a concave cavity, for example, in the full convex bulge of the outer side of the nozzle head housing, which predominates in the state of the art, the cleaning liquid would tend more to run down or up and detach prematurely from the surface.

Detailed description

For the exemplary representation of the essential features of the invention, then in all cases a container cleaning device 1 in an embodiment (Figures 1 to 3c) in which the drive means 10 is chosen A to generate the rotation movement around an axis of rotation I, II are disposed within the container cleaning device 1 (figures 1a, 1c, 1d) and actuated by the circulation energy of at least a part of the tributary current of cleaning liquid R flowing into the container cleaning device 1.

The container cleaning device 1 (figures 1a to 1e) is composed in its upper area, with respect to the preferable mounting position shown (figures 1a, 1b, 1e), of a housing body 2 with a head housing of nozzle 3 arranged below and of a nozzle head 4 with at least one nozzle 19. In the exemplary embodiment, four of these nozzles 19 are provided uniformly arranged along the contour of the nozzle head 4. The body of housing 2 is composed in its upper area of a housing of connection 2.1 with a supply conduit 2.1d fixedly connected thereto, in which an orifice is made of

feeding 2.1a, and in its lower zone, of a first tapered wheel 2.3 and a first hollow wheel 2.4 with

Toothed Interior, fixedly located next to it at a distance, the first conical wheel 2.3 and the first hollow wheel 2.4 being connected to the connection housing 2.1 through a fixing rod 2.2 made therein on the side of is. The area of connection between the first conical wheel 2.3 and the first hollow wheel 2.4 is made permeable to the liquid through several first holes 2.5 distributed along the contour. In addition, the connection housing 2.1 can be provided in two other variants (2.1 *, figures 3a to 3c; 2.1 **, figures 4 a

9).

The nozzle head housing 3 is made as a hollow body which in a configuration of the first type is extended, on the side of the connection housing 2.1, in the form of a housing rod 3a fixedly connected,

preferably in one piece, to the nozzle head housing 3. Said housing stem 3a formed in the

inside a first housing opening 3b, through which there is a first access to the interior space of the nozzle head housing 3. On the side of the nozzle head 4, the nozzle head housing 3 has a second opening of housing 3c, through which there is a second access to the interior space of the housing of nozzle head 3. The unit preferably made in one piece, consisting of the fixing rod 2.2, the first tapered wheel 2.3 and the first hollow wheel 2.4 with internal teeth, is introduced through the second housing opening 3c into the nozzle head housing 3 and through the first housing opening 3b is joined by geometric and / or forced connection, for example by threaded connection , with connection housing 2.1 approaching from above.

40

Between an undesignated offset in the nozzle head housing 3, which comprises the first housing opening 3b in the transition zone between the nozzle head housing 3 and its housing rod 3a, and the first conical wheel 2.3 is provided with a first bearing 11.1 preferably equipped as a ball bearing (figure 1b) which serves for the rotating support of the nozzle head housing 3 on the connection housing 2.1 45 around the first axis of rotation I extending coaxially with respect to the connection housing 2.1 and the supply conduit 2.1d thereof. A second support point for the nozzle head housing 3 is axially provided a little more on the outer side of the first hollow wheel 2.4 with internal teeth in the form of an undesignated bearing.

50 The housing rod 3a wraps the connection housing 2.1 with its first housing opening 3b. It is supported respectively by its ends through a first slide ring 16a of a first slide bearing 16 or through a second slide ring 17a of a second slide bearing 17, rotatably about a rotation axis I, on the connection housing 2.1, and forms in the axial direction between these two slide bearings 16, 17 and in the radial direction between each other and the connection housing 2.1 an annular chamber 13 which through bypass channels 2.1b in the wall of the connection housing 2.1 is communicated with the supply opening 2.1a. Conveniently, the sliding rings 16a, 17a are radially dimensioned in such a way that by the bearing gap existing in them respectively there is a minimum liquid passage according to the effective pressure differences in the sense of a self-cleaning of these zones. Through the first slide bearing 16, this liquid transport also continues to

through the first bearing 11.1 to the interior space of the nozzle head housing 3.

The second housing opening 3c in the nozzle head housing 3 is coaxially oriented with respect to the second axis of rotation II which preferably crosses the first axis of rotation I and extends perpendicularly with respect to this. A second conical wheel 5 is inserted through the second housing opening 3c into the nozzle head housing 3. The second conical wheel 5 is arranged coaxially with respect to the second axis of rotation II and engages with the first conical wheel 2.3. The housing of the second conical wheel 5 is carried out on the Left side through a second bearing 11.11 preferably made as a ball bearing held on one hand by the second conical wheel 5 and on the other hand by an unspecified fixing ring, screwed on. in the second housing opening 3c, and on the right side through an undesignated sliding ring that is disposed between the aforementioned fixing ring and the nozzle head 4. The second conical wheel 5 ends on the inner side in a central hub 5a which is connected by threaded connection with the nozzle head 4.

As axial continuation of the supply opening 2.1a, within the connection housing 2.1 and the unit 15 made in one piece, located below, composed of the fixing rod 2.2, the first conical wheel 2.3 and the area of transition to the first hollow wheel 2.4 with internal toothing, and coaxially with respect to the first axis of rotation I is arranged a turbine 6 driven by the circulation energy of the affluent stream of cleaning liquid R that flows to the container cleaning device 1 through the supply opening 2.1a. Seen in the direction of movement, the turbine 6 is composed of a crown of guide vanes 6b 20 fixedly attached to the stationary carcass body 2, with several guide vanes and a runner 6a with several guide vanes. The impeller 6a is fixed on a turbine shaft 7 which is supported by a part in the area of the crown of guide vanes 6b in a fifth bearing 12.3 and, on the other hand, in the area of a second hollow wheel 10 with internal teeth , fixedly below the first hollow wheel 2.4 with internal teeth inside the nozzle head housing 3, through a third bearing 12.1.

25

The turbine shaft 7 carries at its opposite end to the crown of guide vanes 6b a cogwheel made as a satellite wheel 8 (Figure 1c) that meshes with a planetary gear 9 composed of at least two planetary wheels. The planetary wheels are provided respectively along their total axial extension with a single continuous gear respectively, gearing each planetary wheel with one end in the first hollow wheel 30 2.4 with internal gear fixedly attached to the connection housing 2.1 and with the other end in the second hollow wheel 10 with internal teeth, coaxial to the latter and fixedly attached to the nozzle head housing 3. The two planetary wheels rotating on the inner side around the satellite wheel 8 and on the outer side in the Hollow wheels 2.4 and 10 are rotatably supported on the one hand in the area of the third bearing 12.1 and on the other hand on the turbine shaft 7 through a fourth bearing 12.2, seen in the axial direction.

35

The drive mode of a container cleaning device 1 of this type that receives its drive energy through the turbine 6 driven by the circulation energy of the cleaning medium is widely known in the state of the art (for example, EP1062049B1). Because of the difference in the numbers of teeth for the first hollow wheel 2.4 with internal teeth and the second hollow wheel 10 with internal teeth 40, which has to be at least one tooth, during each complete rotation of the planetary wheels around The satellite wheel 8 produces a relative displacement of the hollow wheels 2.4 and 10 in the circumferential direction with respect to the first axis of rotation I. This relative rotating displacement causes the second conical wheel 5 to rotate towards the first conical wheel 2.3 stationary ( rolling movement) thus producing a rotation of the nozzle head 4 with respect to the nozzle head housing 3 around the second axis of rotation II 45 with a second number of revolutions nn, so that at the same time a rotation of the nozzle head housing 3 with respect to the housing body 2 stationary around the first axis of rotation I with a first number of revolutions ni.

In the housing rod 3a a first housing bore 3f is provided that serves to receive at least an independent first 50 additional nozzle 30. The latter can be fixed in the housing bore 3f by joining materials (for example, by welding) or by geometric and / or forced union (for example, by threaded joint or pressure insertion). The exemplary embodiment shows the first additional nozzle 30 in the form of a flat jet nozzle. The latter is communicated with the supply opening 2.1a through the annular chamber 13 and the bypass channels 2.1b and distributes to the envelope surface of the container a second partial stream R2 55 fed from the affluent stream of the cleaning liquid R. Since the housing rod 3a is fixedly connected to the nozzle head housing 3, the first additional nozzle 30 obligatorily rotates synchronously with the nozzle head housing 3 around the first axis of rotation I. The first additional nozzle 30 is arranged on the contour of the housing rod 3a (see Figure 1d) in such a way that the crossing of the second spray jets of the second partial stream R2 leaving the first nozzle is safely prevented

additional 30 with a first partial stream R1 leaving the nozzles 19 in the nozzle head 4 which generates first spray jets. If two additional nozzles 30a are to be provided in the housing rod 3a, these are conveniently arranged diametrically opposite, their symmetry axes being oriented preferably at 90 degrees with respect to the second axis of rotation II.

In a configuration of the second type, the annular chamber 13 is delimited with respect to the environment through a first nozzle housing 14 (Figures 2a, 2b and 2c) that in a second housing bore 14a receives the first additional additional nozzle 30. The first nozzle casing 14 is rotatably supported on the connection casing 2.1, the support being made at its lower end through a third sliding ring 10 18a of a third sliding bearing 18, and is in the drive coupling of shape with the nozzle head housing 3. In the exemplary embodiment, this drag connection is made such that the first nozzle housing 14 has at its lower end a first drag cavity 14b (figures 2b, 2c) in which gears a drive pin 20 geometrically inserted into the upper end of the nozzle head housing 3. This configuration of the second type also corresponds to the configuration of the first type in terms of structure and mode of action.

The configuration of the second type shown above undergoes a modification, because now the nozzle housing is made domed in the radial direction but more compacted in the axial direction and thus takes the form of a second nozzle housing 15 ( Figures 3a, 3b and 3c). This conformation leads to the modified connection housing 2.1 *, more compact in the axial direction, and bypass channels 2.1b * modified, axially displaced and now allows the realization of a first additional nozzle 15a * of the integrated form and, given the case, of a second additional nozzle 15b * of the integrated form, respectively by the wall of the second nozzle housing 15 itself (figures 3a, 3c). The second nozzle casing 15 is in turn in a trailing connection with the nozzle head casing 3. This trailing junction 25 is made correspondingly to that of the first nozzle casing 14, presenting the second carcass of nozzle 15 at its lower end a second carrier cavity 15c (FIG. 3b) in which the drag pin 20 inserted in the upper end of the nozzle head housing 3 engages in geometric connection.

The nozzle head housing 3 may additionally have at least one additional nozzle 30.1, 30.2, 3d *, 30 3e * additional (figure 1b), which may be a second additional nozzle 30.1 independent and a third additional nozzle 30.2 independent and / or of a second additional nozzle 3d * integrated and of a third additional nozzle 3e * integrated. In the embodiment, two additional nozzles 3d *, 3e * are provided. These are fed from a fourth partial stream R2.1 and a fifth partial stream R2.2 which together with the first partial stream R1 are also generated from the differential stream of cleaning liquid R to R2 that drives the turbine 6. The additional nozzles 30.1, 30.2, 3d *, 3e * are generally oriented in such a way that the spray jets distributed therein exit to the inner envelope surface of the container. In the exemplary embodiment, the second additional nozzle 3d * integrated is arranged in the transition zone of the nozzle head housing 3 between the surrounding area of the nozzle and its frontal delimitation surface, being the preferable arrangement point, since There are the most favorable geometric conditions here.

40

In addition, any point in the nozzle head housing 3 that has free access to the interior space of the nozzle head housing 3, in particular, is suitable for the arrangement of the additional nozzles 30.1, 30.2, 3d *, 3e * with respect to the axial extension zone thereof along the first axis of rotation I. As the exemplary embodiment shows as for the third additional nozzle 3e * integrated, as an additional possible point, the envelope area of the nozzle head housing 3 between the first tapered wheel 2.3 and the first hollow wheel 2.4 with internal teeth. In addition, the area of the second hollow wheel 10 with internal teeth is conditionally suitable for this.

The orientation of the respective additional nozzle 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e * in the area of the stem of the 50 housing 3a or the nozzle housing 14, 15 or the nozzle head housing 3 can be carried out in such a way that the line of action of the axis of symmetry of the respective additional nozzle crosses the first axis of rotation I. But the corresponding line of action of the axis of symmetry can also have a radial distance of the first axis of rotation I In the arrangement and orientation of the additional nozzles 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e * it is decisive that they approach their respective cleaning liquid R2, R2.1, R2.2 in any case to the envelope surface of the container.

55

The additional nozzles 30, 30.1, 30.2, 15a *, 15b *, 3d *, 3e * are advantageously made as flat jet nozzles that produce a fan-shaped flat jet, extending the flat jet extension surface in one preferred embodiment in parallel with respect to the first axis of rotation I. The flat jet nozzles thus arranged in the upper area of the nozzle head housing 3 or in the housing rod

3a or in the nozzle housings 14, 15 are suitable to reach in addition to the enclosure area of the container also the upper bottom thereof.

As shown in Figures 1b, 1 d, 1 e, 2b and 2c, the independent nozzle 30, 30.1, 30.2 is fixed within 5 the nozzle head housing 3 by joining materials (for example, by welding) or by geometric and / or forced connection (for example, by threaded connection or by pressure insertion). But the additional nozzle of the Integrated form 15a *, 15b * or the additional integrated nozzle 3d *, 3e * can also be formed by the wall of the second nozzle housing 15 or the nozzle head housing 3 or, if necessary , of the housing rod 3a itself. In this case, the latter have to be opened by drilling according to the necessary nozzle size and at the outlet point 10 of the spray jet an additional milling must be performed if a flat jet nozzle is to be provided.

From the flowing stream of cleaning liquid R flowing through the supply opening 2.1a to the Inner space of the connection housing 2.1, 2.1 * (Figures 1a to 3c) is derived through the bypass channels 2.1b, 2.1b * the second partial stream R2 which is distributed through the first additional independent nozzle 30 or 15 additional nozzles of the integrated form 15a *, 15b * to the envelope surface of the container in the form of a so-called rotary blast cleaning around the first axis of rotation I. The differential current of cleaning liquid R to R2 (figures 1a, 1b) completely crosses the crown of guide vanes 6b and the impeller 6a located below to divide from here, a partial current flowing through the first through holes 2.5 arranged above the planetary gear 9 and then through second through holes 5b in the second 20 conical wheel 5 to the tober head 4, through another partial current, first of all, the planetary gear 9 to reach the nozzle head 4 in part through the second through holes 5b. Through the nozzles 19 of the nozzle head 4, the first partial current R1 comes out in its entirety, the nozzles 19 carrying out a superimposed three-dimensional turning movement, whereby after a certain interval of time the totality of the inner surface of the container.

25

Another partial current arrives through the first holes 2.5 above the planetary gear 9 as fifth partial current R2.2 to the additional nozzle 3e *, 30.2. From the partial current through the planetary gear 9, a certain part arrives as the fourth partial current R2.1 to the additional nozzle 3d *, 30.1.

30 The cleaning liquid that passes through the second through holes 5b in the second conical wheel 5 branches into the first partial stream R1 (first spray jets) and a third partial stream R3 (third spray jets) (figures 1 d, 1e, 2c and 3c). The first partial stream R1 reaches the nozzles 19 in the nozzle head 4, all the nozzles 19 together distributing the first partial stream R1 to the container to be cleaned. The third partial stream R3 reaches a spray device 4a made as a nozzle at the outer edge 35 of the nozzle head 4 and is rotatably applied to the nozzle head housing 3 on the one hand as a result of the rotation of the nozzle head 4 around the second axis of rotation II (second number of revolutions nM). On the other hand, the nozzle head housing 3 makes a rotation around the first axis of rotation I (first number of revolutions n), such that the third partial current R3 also reloads the cleaning surface also always with the surface of the housing stem 3a or nozzle housing 14, 15 above 40 nozzle head housing 3. Partial currents R2, R2.1, R2.2 from additional nozzles 30. 30.1, 30.2, 15a *, 15b *, 3d *, 3e * rotate around the first axis of rotation I and constantly drip the envelope surface of the container, whereby the objective according to the invention is achieved.

The container cleaning device 1 of Figures 4 to 7 and Figure 9 has already been described above in general lines 45. Therefore, from now on, reference is only made to special details that are either not designated in the figures described above in the drawing or that refer especially to the self-cleaning of the container cleaning device 1.

In the embodiment shown in Figure 4, the nozzle head housing 3 ends slightly above 50 of the first slide bearing 16 which functions as a radial bearing. In addition to the first bearing 11.1 preferably made as a ball bearing, which acts as an axial bearing, a second support point is provided for the radial support of the nozzle head housing 3 which is axially arranged a little more on the outer side of the hollow wheel 2.4 with internal toothing in the form of a sixth bearing 31. The latter is preferably made as an annularly closed sliding bearing which is composed of a support ring 31a 55 preferably metal and a third sliding ring 31b. Although this sixth bearing 31 is disposed in the area of the second carcass opening 3c it is enclosed by the nozzle head carcass 3 except this carcass opening area and, therefore, can serve for its stable support on the first hollow wheel 2.4 with internal teeth that peek into the interior area of the nozzle head housing.

Between the connection housing of the second type 2.1 ** in combination with the fixing rod 2.2 and the first tapered 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 communicating the interior space of the nozzle head housing 3 to the environment of the container cleaning device 1 through the first bearing 11.1. In the course of this circumferential annular gap 5, the first sliding ring 16a of the first sliding bearing 16 is arranged before it enters the environment of the container cleaning device 1.

The support of the second conical wheel 5 is made through the second bearing 11.11 preferably made as a ball bearing, which is held on the one hand by the second conical wheel 5 and on the other hand by a fixing ring 10 screwed on the second housing opening 3c.

Between the nozzle head 4 on the one hand and the fixing ring 21 in combination with an edge of the non-designated nozzle head housing 3, which comprises the second housing opening 3c, on the other hand, a second annular gap is made circumferential 33 that communicates the interior space of the nozzle head housing 15 3 to the environment of the container cleaning device 1. In the course of this second circumferential annular gap 33, before its exit to the environment of the container cleaning device 1 a fourth sliding ring 23a is formed which forms a fourth sliding bearing 23 in the nozzle head housing 3 in combination with the fixing ring 21 on the one hand and the nozzle head 4 on the other hand, with respect to the second axis of common twist II of these. The fourth slide bearing 23 performs the second support point 20 for the second tapered wheel 5 in combination with the nozzle head 4 inside the nozzle head housing 3.

The second hollow wheel 10 with internal teeth is introduced, during the assembly of the container cleaning device 1, into the interior space of the nozzle head housing 3 through the second housing opening 25 3c and is immobilized in a non-fixed manner. movable in its final position inside the nozzle head housing 3 through a fixing element 22, for example a captive screw.

The satellite wheel 8 meshes with the planetary gear 9 composed 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 along their total axial extension with a single continuous second gear, each planetary wheel 9.1, 9.2 engaging with a

end on the first hollow wheel 2.4 with internal teeth fixedly attached to the connection housing of the second

type 2.1 **, and with the other end in the second hollow wheel 10 with internal gear, coaxial to the latter and fixedly attached to the nozzle head housing 3. The satellite wheel 8 with the first gear is made with a number of teeth zs = 6, while the two planetary wheels 9.1 and 9.2 performed in the same way must be provided respectively with the second gear (number of teeth Z9.1 = z92 = 22). The first hollow wheel 2.4 with internal teeth has a third gear (number of teeth z2.4 = 50) and the second hollow wheel 10 with internal teeth has a fourth gear (number of teeth z-io = 52).

The cleaning liquid R which flows through the supply opening 2.1a into the interior space of the housing

40 connection of the second type 2.1 ** completely crosses the crown of guide vanes 6b with the vanes

guidelines 6b * and the impeller 6a with the impeller blades 6a *, located below, to divide from here, a partial current flowing directly to the nozzle head 4 through through holes 2.5 arranged above the planetary gear 9, passing through another partial current first the planetary gear 9 to arrive from there, also through the holes 2.5 in the second conical wheel 5, to the nozzle head 45 4. The toothed wheels of the conical wheels 2.3 and 5, the toothed of the planetary gear 8, 9, 2.4 and 10, the supports 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 4 are subjected to these partial streams of the cleaning liquid R.

The first circumferential annular gap 32 with its first sliding bearing 16 and the second circumferential annular gap 50 with its fourth sliding bearing 23 have a permeability to the cleaning liquid r4 (sliding bearing leakage) or r5 (second bearing leakage of sliding) limited, determined by the respective bearing clearance, which is sufficient to clean these areas respectively. Also the first bearing 11.1 arranged before the first circumferential annular gap 32 is subjected to sufficient cleaning liquid, so that also in this area a good self-cleaning occurs.

55

The cleaning liquid R or R to R2 (the differential current R to R2 exists when the second partial current R2 is derived before the turbine 6) that passes through the through holes 5b in the second conical wheel 5 (see Figure 7) , branches into the first partial stream R1 (first spray jets) and the third partial stream R3 (third spray jets). The first partial current R1 arrives through a connection hole 4d at a

supply hole 4c in the nozzle head 4, four of these connection and supply holes 4d, 4c being provided in the exemplary embodiment and each of the supply holes 4c at the end in the assigned nozzle 19 (see also Figure 5). All the nozzles 19 together make the first partial current R1 to the container to be cleaned. Seen in the direction of circulation, the third partial current R3 arrives before reaching the fourth sliding bearing 23 to an independent supply channel 4b (Figures 4 and 7), through which the spray device 4a made as a nozzle is fed completely inside the nozzle head 4.

Therefore, to the nozzles 19 of the nozzle head 4 which are provided for the cleaning itself of the container comes the first partial stream R1 (first spray jets) that results from the cleaning liquid R (main stream) entering to the container cleaning device 1 through the supply opening 2.1a, to deduct all the partial streams derived to the nozzles 19. In the third partial stream R3 that exits through the spray device 4a it is a third spray jet configured as intended to be applied rotationally in the nozzle head housing 3 on the one hand as a result of the rotation of the nozzle head 4 around the second axis of rotation II (second number of revolutions ñu) (see especially the Figures 5, 6 and 9). On the other hand, the nozzle head housing 3 makes a rotation around the first axis of rotation I (number of revolutions ni), such that the third partial current R3 is also applied again and again on the surface of the housing of connection of the second type 2.1 ** or of the housing rod 3a (figures 1a to 1e) or of the nozzle housing 14, 15 above the nozzle head housing 3 (figures 2a to 3c).

The first and second sliding bearing leaks r4, r5 do not produce pronounced spray jets, but in this case a moderate self-cleaning is carried out from the inside out, while the removal of possible dirt removed from the circumferential annular interstices 32 and 33 or supplies these from outside is performed by the third partial current R3. The mode of action of the spray device 4a 25 performed as a nozzle is especially illustrated by the representations of Figures 5, 6 and 9. Especially the representation according to Figure 9 shows that the third partial current R3 leaving the spray device 4a reaches the exit zone of the second circumferential annular interstitium 33.

In order to guarantee an optimum realization of the first spray jets of the first partial stream R1 30 leaving the nozzles 19, the corresponding supply hole 4c towards the assigned nozzle 19 is made with a maximum possible length (Figure 5), as the drawing of a nozzle 19 is shown. This is achieved because the longitudinal axis of the inflow hole 4a forms the tangent to a circle K concentric to the second axis of rotation II, with a radius a. This radius a is made as large as possible, ensuring that the corresponding connection hole 4d does not engage in the supply hole 4c adjacent or the adjacent nozzle 19.

35

With a view to sufficient self-cleaning of the container cleaning device 1, on the outer side of this a difficult area is reached in the nozzle head housing 3, which is opposite to the nozzle head 4, if it is not desired to install, as is the case, for example, in the container cleaning device according to EP1062049B1, a separate nozzle in the upper area of the connection housing 2.1 **, 2.1, 2.1 * which in turn would be a problem for cleaning.

In order to reach the problematic surface area in question of the nozzle head housing 3 with cleaning liquid with the third partial current R3 leaving the spray device 4a, the invention provides that the outer side of the nozzle head housing 3 ( see especially figures 5, 6 and 9), respectively, provided on both sides and symmetrically to a plane that runs along the first and second axes of rotation I, II, with a slightly concave 3 * cavity that presents respectively curved transitions in opposite directions towards the adjacent outer sides of the nozzle head housing 3. In the phases of the cleaning process in which the third partial current R3 directly drips the concave cavity 3 * directly, the cleaning liquid that strikes there, especially if it affects the outer areas of the cavity 3 * concave, run, 50 because of this special conformation of the surface, rather ia the deepest point of the concave cavity 3 * to run from it as a film of liquid adhered to the surface (see especially Figure 6) towards the surface area of the nozzle head housing 3, away from the nozzle head .

A second embodiment of the container cleaning device 1 according to the invention (Figure 8) is characterized with respect to the first embodiment according to Figure 4 because the first circumferential annular gap 32 is oriented, in the area of its outlet around the drive device 1, not in parallel with respect to the first axis of rotation 1 as is the case in Figure 4, but has an orientation oriented at least perpendicularly with respect to the first axis of rotation I or even slightly downward. In this way, the first sliding bearing leakage r4 can exit without obstruction from the first annular gap.

circumferential 32 out radially. In addition, in the corresponding phases of the nozzle head rotation process 4, the third partial current R3 leaving the spray device 4a directly affects the first circumferential annular gap 32, so that here an especially effective cleaning of dirt can occur .
