Description

DESCRIPTION

Internal container cleaner

5 The present invention relates to a device for cleaning internal surfaces of containers, in particular barrels or tanks.

Devices of this type are known from each other. If appropriate, by means of a fluid that impacts the internal surfaces in the form of at least one stream of fluid, the internal surfaces of the container are cleaned. Typically, water is used as a fluid, where appropriate with additives such as surfactants or the like. In the cleaning of wooden wine barrels, however, inspired water without additives is preferably used.

Such devices generally contain a pressure conduit that extends from a water inlet of the device through the device to a nozzle area that has at least one nozzle orifice, as well as a suction conduit that extends from to the less a zone of aspiration of the device that has at least one orifice of aspiration towards a water outlet of the device. The water outlet can be disposed in this case outside the container to be cleaned, and the nozzle area as well as the suction zone of the device can be arranged in this case inside the device to be cleaned. Therefore, water is emitted from the nozzle area inside the container to be cleaned in its interior walls, whereby the impurities adhered to the interior walls are mechanically removed and / or dissolve or gradually dissolve. of the interior walls. The water that bounces off the interior walls, that drips or flows through them, carries these impurities and eventually accumulates in the deepest place in the container. From there, the water along with the impurities is aspirated through the aspiration zone and carried to the fluid outlet. In this way the interior walls of the container become increasingly clean.

25

In conventional devices of this type of construction, separate drives (pumps) are used for the pressure line and for the suction line. Also in the case of the cleaning device for internal container spaces, in accordance with EP 2 002 901 A2, which is intended for containers that are housed one above the other and therefore have limited accessibility into the interior of 30 bowl

In the case of the device for automatic cleaning of containers according to document BE 508 339 A, a suction duct is provided that operates in accordance with the Venturi principle. A requested cleaning fluid with pressure circulating through a pressure connection to the device can drive the fluid transport in the suction line.

The invention is based on the objective of simplifying the construction, as well as the handling of such a device.

To achieve this objective, the invention provides a device for cleaning internal surfaces of 40 containers, in particular barrels or tanks by means of a fluid that impacts in the form of at least one jet of fluid on the internal surfaces, in accordance with the independent claim 1.

When the fluid source is connected to this device it supplies both the energy for the transport of fluid in the first fluid path, that is to say in the pressure line, as well as for the transport of fluid in the second fluid path, it is say in the suction duct

As a fluid, liquids and / or gases or mixtures thereof, in particular water and / or air, but also other liquids such as oil can be used. For special uses, in particular for cleaning wooden wine barrels, pure water can be used. In other uses, other liquids or liquids with suspended solid matter particles, particularly abrasive (micro or nanoparticles) may also be used. There are also uses in which solid matter particles carried in a gas are used.

According to a particularly advantageous embodiment of the device, the source of fluid that can be connected to the fluid inlet is the only active actuation element of the device, while all other elements of the device are passive elements, that is to say direct actuated or indirectly through the energy of the fluid source. This facilitates the treatment with the device according to the invention. After the nozzle head and the suction head have been inserted inside the container to be cleaned only this fluid source or energy source must be connected to the device to begin therefore cleaning the internal surfaces of the container.

60

As a source of fluid, a water accumulator with a water pump, a compressor to generate compressed air or simply a water accumulator arranged higher with respect to the device, such as the public water supply network, can be used. An oil reservoir with an oil pump can also be used as a source of fluid, eg in the form of a cogwheel pump.

A first fluid transport means may be associated with the first fluid path with which a fluid can be transported through the first fluid path from the fluid inlet to the nozzle area. Preferably the first fluid transport means is disposed within the first fluid path. In the same way, a second fluid transport means can be associated with the second fluid path, with which a fluid can be transported through the second fluid path from the suction head to the fluid outlet. Preferably also the second fluid transport means is disposed within the second fluid path.

In this case, in turn, it is particularly advantageous when both the first fluid transport means and the second fluid transport means can be operated by means of energy, that is to say through the fluid pressure and / or the fluid flow rate of the fluid provided by the connected fluid source, so that during the operation of the device both the hydrodynamic energy of a jet of fluid leaving a nozzle hole and the aspiration energy in a suction hole through the device are provided fluid source connected to the fluid inlet.

fifteen

In a special embodiment the nozzle head represents at least a part of the first fluid transport means, that is to say at least a part of the transformation of the potential and / or kinetic energy of the fluid from the external fluid source into Rotating energy of the nozzle head in and / or on the nozzle head itself. This is, for example, a combination of hydraulic drive-nozzle head, that is to say pulse transmitting elements of the hydraulic drive are arranged inside or on the nozzle head itself.

Conveniently, the nozzle head is a multi-part figure in which a first part of the nozzle head is rotatably housed about an axis of rotation in a housing or duct section 25 of the device according to the invention , and a second part of the nozzle head is rotatably housed around a second axis of rotation in the first part of the nozzle head. The second part of the nozzle head contains a multitude of nozzles, usually one to four nozzles that are arranged as a crown normally along a concentric peripheral direction to the second axis of rotation, about the second axis of rotation. Depending on the case of application, the first and second axis of rotation are arranged at right angles 30 to each other or at an angle less than 90 °. Therefore, liquid jet patterns are obtained that reach the entire internal surface of the container or a partial area of the internal surface of the container with more jet energy correspondingly. In the case of the nozzles arranged as a crown or along a peripheral direction in the second part of the nozzle head, the nozzle shafts may be arranged radially with respect to the second axis of rotation, or inclined with respect to the direction radial of a respective nozzle. This orientation of the nozzles can also influence the liquid jet pattern, that is to say the spray image. The first part of the nozzle head contains a first conical cogwheel that extends concentrically around the first axis of rotation. The second part of the nozzle head contains a second conical cogwheel that extends concentrically around the second axis of rotation, which engages with the first conical cogwheel. The first part of the nozzle head is rotatably driven through the energy of the fluid source and transmits this drive energy through the two conical gearwheels geared to the second part of the nozzle head.

In order to achieve the rotary drive of the nozzle head, the nozzle head is preferably a part of a mechanical drive bar having a first section for transforming the hydrodynamic energy of the fluid into rotating energy of the drive bar, and therefore in rotating energy of the nozzle head. The first part of the nozzle head is in this case driven by rotation by means of the energy of the fluid source through its drive bar and transmits this drive energy through the two conical gearwheels geared to the second part of the head nozzle

The first part mentioned above additionally or the first section of the drive bar can be configured as a gearwheel, as a turbine, as a rotating plunger pump that works in reverse, etc. Between this first section of the drive bar and the rotating nozzle head the drive bar may have an additional part or additional section with a multiplication or reduction gear to adapt the rotational speed of the rotary movement introduced through the first section 55 (gearwheel, turbine, etc.) on the drive bar for the rotating nozzle head. Conveniently, the turning speed generated in the first section is reduced through the gear at a lower turning speed for the rotating nozzle head. Different types of reduction gears can be used as gears, such as planetary gears, "sliding cradle gears", cycloid gears, etc. These reduction gear units can be arranged both in one stage and 60 also in several stages in the additional section (gear section) of the drive wheel, and different types of reduction gear units may also be used mixed in one arrangement. Multi-stage

Alternatively, the function of the first section of the drive bar (gearwheel, turbine, etc.) and the function of the rotating nozzle head or the spray head can be combined with each other, ie the wheel

toothed or turbine etc. on the one hand, and the nozzle head on the other hand, are assembled in one unit, the nozzle channels in the nozzle head being at least in partial areas of the radial expansion of the nozzle head bent or bent in unitary manner with respect to the radial direction.

5 According to an additional alternative, a part of the fluid that circulates through the first fluid path, which supplies the necessary circulation energy for the rotary drive, can branch off from the first fluid path to a path that runs parallel to this, that is to say a first part of the fluid entering from the connected fluid source arrives directly at the rotating nozzle head, while a second part of the fluid entering from the connected fluid source arrives indirectly through the first section 10 above described (gearwheel, turbine, etc.) to the rotating nozzle head. By adjusting the relationship of the division between the direct fluid flow that circulates directly and the indirect fluid flow that circulates indirectly and deals with the rotary drive, an adjustment of the speed of rotation of the nozzle head similar to the mentioned gear can be achieved higher. The advantage in this case is that the adjustment of the ratio, and therefore the speed of rotation of the nozzle head can be carried out without steps or in a staggered manner.

In the case of an additional advantageous embodiment, the aspiration head is arranged in the second fluid path and is actuated by aspiration through the potential and / or kinetic energy of the fluid from the fluid source that can be connected.

twenty

To generate the suction drive for the suction head, in a particularly advantageous embodiment the second fluid transport means operates according to the Venturi principle (injector pump with jet nozzle), forming the fluid from the connected fluid source. suction jet. This has the advantage that no mobile part is required for the generation of the aspiration function.

25

Conveniently, the suction drive contains a suction duct nozzle section, in which a jet nozzle (injector) protrudes, the opening of which opens into the suction duct nozzle section in the suction direction. The jet nozzle is in fluid connection with a pressure duct section. This fluid joint is a bifurcation of pressure line from the pressure line that leads to the nozzle head (spray head). During operation a part of the cleaning liquid that circulates towards the nozzle head, preferably after a part of its energy has been emitted for the transformation into rotating energy of the mechanical actuation bar reaches the jet nozzle, from which it flows in the direction of aspiration towards the nozzle section of the aspiration duct and there it emits an additional part of its energy for the transformation into aspiration energy. In this case, it is particularly advantageous when, in the pressure duct, it is arranged downstream (downstream) from the bifurcation of the pressure duct leading to the jet nozzle, a closing organ, eg in the form of a rotating distributor ( tap). While the source of fluid that provides the energy is connected to the device according to the invention during this establishment of the suction drive, regardless of the position (open or closed) of the closing organ, a continuous suction operation occurs. The supply of cleaning liquid to the nozzle head depends on the contrary of the position of the closing organ. In the case of an open closing organ, cleaning fluid circulates towards the nozzle head. In other words: when the closing organ is open, both cleaning liquid is aspirated from inside the container and cleaning liquid is sprayed into the container, and when the closing organ is closed, only cleaning liquid is aspirated from the inside of the container but no new cleaning liquid is sprayed into the interior of the container.

In an alternative embodiment, for the generation of the suction drive for the suction head the second fluid transport means is preferably a part of the mechanical drive bar or is coupled with it as a drive, which has a second section for transform the hydrodynamic energy of the fluid into the aspiration energy of the suction head.

This second part or second section of the drive bar may be configured similarly to the first section described above as a gearwheel, as a turbine, etc., however in reverse arrangement, that is to say the rotating energy of the drive bar. it is transformed into hydrodynamic energy in the second fluid path.

Preferably, the parts housed in a mobile manner, in particular the parts of the device rotatably housed, between the respective part and the respective bearing have a play or a gap, the fluid acting from the source of fluid connected and penetrating the interstitium acting as fluid lubrication for parts 60 rotatably housed. Through this hydrodynamic housing there are additional measures for lubrication. When a liquid containing micro or nano solid body particles is used as the cleaning fluid, the maximum particle size, that is to say the diameter of the particles approximately in the form of a ball or in the form of a die, should only be a fraction, preferably less than % of this game.

65 Preferably the first fluid path, ie the pressure line, and / or the second fluid path,

that is to say, the aspiration duct runs at least in a partial area of the respective path in a straight line, and can be adjusted in length in this rectilous partial zone. For this, for example, a telescopic arrangement can be provided by means of which the total length of the pressure duct and / or the suction duct can be adjusted. Alternatively, interchangeable suction ducts of different length can be provided at whose 5 ends the suction head is arranged in each case. Thus, in the case of containers of different sizes and / or shapes, it can be guaranteed that the suction head is in contact with the inner wall of the container in the deepest place of the internal space of the container, while the nozzle head is arranged in a central area of the container volume. Therefore, a practically complete aspiration of the cleaning liquid containing the dirt is achieved and at the same time a good distribution of the liquid jet pattern that rotates inside the container.

Preferably the first fluid path, that is to say the pressure line, and the second fluid path, that is to say the suction line run at least in the partial rectilmeate zone parallel to each other and are preferably arranged concentrically with respect to each other. . In this case it is particularly advantageous when the pressure duct has a circular cross-section in the form of a circular crown that extends concentrically around a circular cross-section of the suction duct. For this reason, more power can be fed to the drive bar which also drives the two parts of the nozzle head of the nozzle head (torque x speed of rotation).

20 Preferably, the device has a formation that can be fixed in a sealed manner to an opening of the container to be cleaned, preferably the opening, running both the first fluid path (pressure conduit) and the second fluid path (aspiration conduit ) through training. Conveniently this sealed formation contains a ventilation opening. Therefore, it is prevented that a depression that is too large is created inside the container that hinders the aspiration of cleaning liquid 25 from inside the container or makes it even impossible. An air filter may be inserted in the ventilation opening. Preferably the air filter is interchangeable eg in the form of an air filter cartridge that is inserted into a ventilation channel of the sealed formation.

The device has three formations by means of which it can be supported or fixed in three zones of the container, a first formation of the device can be fixed to the opening of the container to be cleaned and a second formation can be supported, as well as a third formation of the device to an external surface or an internal surface of the container. Normally in the case of a (wine) barrel, the first formation is a barrel eye pivot with a vent hole, the second formation an external support eg in the form of an extensible support patm and the third formation a suction foot with suction head that serves as internal support 35. This ensures a stable three-point positioning of the device with respect to the container to be cleaned.

The actuation of the device according to the invention preferably contains four different construction groups housed in a mobile manner, particularly housed in a manner and contains a total of a maximum of 30 different individual parts.

In a particularly preferred embodiment of the device, particularly suitable for cleaning wine barrels stacked in an outdated manner the suction duct that forms the second fluid path, which extends from the suction zone of the device through the device to the outlet The fluid of the device 45 contains a section that can be spring-loaded, and the drive bar that transmits the rotation energy is preferably also bent. The section that can be angled is in its relaxed resting position, when there is no flexural force, mainly in a straight line. When, for example, a bending force is exerted manually on the section that can be bent, it reaches its tensioned and bent-curved position. In this position, the suction duct of the device can be introduced into the opening of the container that is also to be cleaned without problems ("threading"), when there is little space in the external environment of this container opening. This is the case, eg in wine barrels stacked out of date.

The section that can be bent by spring is preferably a flexible tube which extends inside a helical spring along the longitudinal direction of the helical spring. This section of the suction duct 55 which can be elastically bent preferably forms a bridge between two sections of the selected suction duct, of which one leads to the suction head, and the other to the second fluid transport means, that is to say the actuation of aspiration. The helical spring has passages that are in close contact with each other or even touch with very little play in the axial direction, or no play, preferably less than 1/5 of the filament diameter. Therefore, a high flexural strength is achieved and therefore a high buckling load from which the helical spring / flexible tube section that can be bent from the suction duct is buckled. This high buckling resistance of the helical spring / flexible tube section of the suction duct is important for the support function caused by the suction duct, that is to say by its suction foot,

From the description of examples of realization of the invention that follows now, which is to be understood as limiting, there are advantages, characteristics and possibilities of additional application of the invention by means of the

drawing, showing:

Fig. 1A, 1B and 1C a first example of embodiment of the invention as a perspective view as an exploded drawing or as a sectioned view; and 5

Fig. 2A, 2B and 2C a second example of embodiment of the invention as a perspective view, as an exploded drawing or as a sectioned view.

In Figures 1A, 1B and 1C the first example of embodiment of the invention is shown in the form of an internal container cleaner 10 particularly suitable for wine barrels as a perspective view, as an exploded drawing or as a sectioned view. The internal container cleaner BIR1 has a multitude of constructive elements, of which some are assembled as construction groups, and are described in the additional figures, namely a construction group of suction foot 1, a construction group of nozzle head 2, a barrel eye pivot constructive group 3, a union tube constructive group 4, an injector constructive group 15, a hydraulic drive constructive group 6, a supportive constructive group 7, a handle tube piece 8 , a handle 9 as well as a constructive joint duct group 10.

In the following description of the figures, to simplify, the construction groups designated with the appendix "construction group" and bearing the reference numbers 1, 2, 3, 4, 5, 6, 7 or 10 are also used without the appendix "constructive group". However, the respective construction group is always meant.

In the case of this internal rectile container cleaner BIR1, the axis of the hydraulic drive 6, the axis of the suction foot 1 and the axis of the union tube 4 are essentially located in a straight line. It is particularly suitable for cleaning the interior walls of a wine barrel.

25

To perform an internal cleaning of containers, this internal rectile container cleaner BIR1 is introduced into a container (not shown) and through a hydraulic drive 6 it is connected to a water source (not shown) that provides the drive energy for the BIR1 internal container cleaner. During the introduction the suction foot 1 is inserted through a barrel eye (not shown) of the container into the interior 30 of the container, it being intended that the suction foot 1 abuts its suction head 1 in the deepest place from the internal container space so that at the end of the cleaning process all cleaning water can be drawn from the container.

When the suction foot 1 has been completely inserted into the container the nozzle head 2a is located inside the container. The nozzle head 2a is housed on two axes and has two orthogonal axes of rotation with respect to each other. Therefore, during the cleaning operation through the rotating nozzle head 2a in the form of new cleaning water sprayed by water jets, the entire internal surface of the container to be cleaned can be reached.

40 When the suction foot 1 is fully inserted, the barrel eye pivot 3 provided with a ventilation opening is dragged into the barrel eye of the container to be cleaned.

The union tube 4 is found during the cleaning operation outside the container. Inside the union tube 4, a section 13a of a mechanical drive bar 13a, 13b extends in axial direction, which transmits a rotating movement generated in the hydraulic drive 6 from the hydraulic drive 6 towards the nozzle head 2a. Also inside the union tube 4 in the axial direction extends a section 14a of a suction duct 14a, 14b, which forms a fluid joint between the suction head 1a of the suction foot 1 and the injector 5. Therefore during The cleaning operation can be used to clean cleaning water used by means of the depression generated in the injector 5 through the suction foot 1 from inside the container. Finally, a section of a pressure conduit (not visible in Fig. 1), which forms a fluid connection between the hydraulic drive 6 and the nozzle head 2a, also extends axially inside the union tube 4. Therefore, during the cleaning operation, water fed to the nozzle head 2a can be fed through the connected external water source.

55 The union tube 4 contains a high pressure connection fitting 4a that protrudes transversely from it through which the high pressure conduit that reaches the nozzle head 2a is connected to the conduit section

12 of the diverting duct 8, 9, 10, 12. The connecting tube 4 also contains a suction connection fitting 4b protruding transversely from it through which the suction conduit that reaches the suction head 1a is connected to the injector 5.

The section 13a disposed inside the union tube 4 of the mechanical drive bar 13a, 13b is also configured as a tube, so that in addition to the transmission of the rotating movement generated by the hydraulic drive 6 also forms the section14a of the conduit duct suction 14a, 14b disposed inside 65 of the union tube 4. In an axial area of the union tube 4, in which the connection connection of

Aspiration 4b, an intermediate chamber indicated 15 is located inside the junction tube 4, in which the terminal area directed to the hydraulic drive 6 of the suction duct 14a or of the drive bar section 13a is axially penetrated through of a fluid-tight rotating bearing (at 16). Through one or more openings 17 in this terminal area of the suction duct 14a or the section of the drive bar 13a the continuity of the suction duct 14a, 14b is also guaranteed in operation with the rotating drive bar 13a, 13b and with the rotating opening or opening 17. The high-pressure conduit mentioned in the preceding paragraph is formed in its section that runs in the union tube 4, therefore, by a channel with a circular crown cross section between the inner surface of the tube of union 4 and the external surface of the section of drive bar 13a which also serves as a section of conduit of aspiration 14a.

The injector 5 forms the suction drive of the internal container cleaner BIR1. In a suction duct nozzle section 5a, a jet nozzle 5b (injector nozzle) protrudes, the opening of which opens into the suction duct nozzle section 5a in the suction direction. This jet nozzle 5b is in fluid connection with a pressure conduit section 18 through a pressure conduit branch 19 from the pressure conduit leading to the nozzle head 2. During operation, in addition to a portion of the water high pressure circulating towards the nozzle head 2 forks towards the injector 5 and flows there into the suction duct nozzle section 5a. In the pressure duct section 18 downstream (downstream) of the pressure duct branch 19 leading to the jet nozzle 20, a shut-off tap 20 is arranged. With the shut-off tap 20 open, water circulates to the nozzle head With the shut-off tap 20 closed, no water flows to the nozzle head. When the shut-off tap 20 is open, so much water is drawn from inside the container and water is sprayed into the container; and when the shut-off tap 20 is closed, only used or dirty water is drawn from inside the container, but fresh water is not sprayed into the container.

25

The hydraulic drive 6 forms the first section of the mechanical drive bar, which extends from the hydraulic drive 6 through the section of the drive bar that extends axially inside the union tube 4 to the nozzle head 2nd. The hydraulic drive 6 contains a gearwheel indicated with 6a, whose output shaft is rotatably connected with the input shaft of a gear indicated with 6b. The gear 6b contains three planetary gear stages (not shown) to adapt the turning speed to the rotating movement introduced through the gearwheel 6a in the mechanical drive bar for the rotating nozzle head 2a.

The support 7 is fixed to the pressure conduit in an area where from this the bifurcation of the pressure conduit 35 forks towards the jet nozzle 5b. The support 7 extends essentially parallel to the union tube 4 and has at its end a foot 7a, which corresponds to the curvature of the external surface of a wine barrel. Together with the suction head 1a at the end of the suction foot 1 and the barrel eye pivot 3, this support 7 forms with its foot 7a a stable three-point housing of the internal container cleaner BRI1 in the container to be cleaned , and particularly in a wine barrel.

40

The joint duct 10 forms a part of the pressure duct represents a diverting duct 8, 9, 10, 12 that deflects as a parallel branch a partial section of the mechanical drive bar 13a, 13b extending axially inside the tube of junction 4. This diverting duct 8, 9, 10, 12 containing the junction duct 10 flows from the terminal area of the hydraulic drive 6 downstream. The diverting duct 45 is then branched on one side into a first branch of the duct leading to the pressure duct section leading to the nozzle head 2 inside the union tube 4, and on the other hand on a second branch duct leading to the suction duct section leading to the suction foot 1 inside the junction tube 4. This second branch duct of the diverting duct thus forms the bifurcation of pressure duct 19 mentioned above. towards the injector jet nozzle 5.

In the figures. 2A, 2B and 2C shows the second embodiment of the invention in the form of an internal container cleaner particularly suitable for wine barrels stacked in an outdated manner as a perspective view, as an exploded drawing or as a sectioned view. The internal container cleaner BIR2 has a multitude of construction elements, some of which are represented together as construction groups 55 and are described in the additional figures, namely a 1 * suction foot construction group, a nozzle head construction group 2, a barrel eye pivot constructive group 3, a union tube constructive group 4, an injector constructive group 5, a hydraulic drive constructive group 6, a supportive constructive group 7, a conduit constructive group of union 10, as well as a construction group of angular gear 11.

60

In the following description of the figures, to simplify, the construction groups designated with the appendix "construction group" and bearing the reference numbers 1 *, 2, 3, 4, 5, 6, 7, 10 or 11 are also used without the appendix "constructive group". However, the respective construction group is always meant.

65 In this internal vessel cleaner, angled BIR2, the axis of the suction foot 1 * and the axis of the union tube 4 are

they lie essentially on a line, while the axis of the hydraulic drive 6 is angled with respect to this line. It is particularly suitable for cleaning the interior walls of stacked wine barrels in an outdated manner.

The internal cleaner of containers BIR2 differs from the internal cleaner of containers BIR1 fundamentally in 5 two points.

The first essential difference is that the suction foot 1 * of the internal container cleaner BIR2 has a suction foot section 1b that can be spring-loaded.

10 The second essential difference is that the internal container cleaner BIR2 does not contain any piece of handle tube 8 or any handle 9 (see Fig. 1). Instead, there is the hydraulic drive 6 arranged in an angled manner. The bending of the mechanical drive bar that extends from the hydraulic drive 6 through the inside of the union tube 4 to the nozzle head 2a is carried out through the angular gear construction group 11 disposed between the hydraulic drive 6 and the union tube 4.

fifteen

The suction foot 1 * has a suction foot section 1 b that can be bent by spring containing a flexible tube 21, which extends inside a helical spring 22 along the longitudinal direction of the helical spring. This section of the suction duct 1 b which can be elastically bent from the suction foot 1 is disposed between the two sections of the suction duct, of which one leads towards the suction head 1a and the other towards the suction drive, that is to say the injector 5. In the exemplary embodiment shown, the section of suction duct 1 b that can be bent by spring is located between the suction head 1 a disposed at the end of the suction foot 1 * and the nozzle head 2a arranged at the end of the pressure line.

25 The angular gear 11 has two shafts angled towards each other 11 a, 11 b, of which one 11 is rotatably connected with the output shaft downstream of the hydraulic drive 6, and the other 11 b with the section 13a of the mechanical drive bar that extends inside the union tube 4 in the axial direction towards the nozzle head 2. The cranked mechanical drive bar formed in this way transmits the rotation movement generated in the hydraulic drive 6 from hydraulic drive 6 to 30 nozzle head 2a.

Since the nozzle head construction group 2, the barrel eye pivot construction group 3, the union tube construction group 4, the injector construction group 5, the hydraulic drive construction group 6, the construction group of support 7, as well as the union duct construction group 10, are identically contained both in the internal rectile container cleaner BIR1 and in the internal container cleaner layered BIR2, at this point the description of these constructive groups given already exists by Fig. 1A, 1B and 1C.
