Description

The invention relates to a spray device for spraying fluids.

From the DE 199 38 435 cleaning device for containers is known, which comprises a spray head and a bearing part, wherein the spray head is rotatably held on the bearing part by means of a bearing, wherein a spacing is arranged between the bearing part and the spray head, which is in spatial connection with the environment, and wherein the spray head has at least one spray nozzle to which the rinsing liquid can be fed by means of a rinsing agent feed line. It is also provided that the spacing space is in spatial connection with the detergent supply line.

The object of the invention is to provide a spray device which enables an improved cleaning effect.

This object is achieved for a spray device of the type mentioned at the outset with the features of claim 1. The spray device according to the invention comprises a spray boom which has an outer tube, an inner shaft rotatably mounted in the outer tube about a first axis of rotation and a nozzle carrier coupled to the inner shaft and rotatably mounted relative to the outer tube, a first nozzle carrier on the outer tube Input connection for providing a first fluid to the spray boom and a second input connection for supplying a second fluid to the spray boom are formed, the first input connection being connected in fluidic communication with a first fluid channel in the outer tube and with a first nozzle channel in the nozzle carrier, and the second inlet connection is connected in a fluidically communicating manner to a second fluid channel in the outer tube and to a second nozzle channel in the nozzle carrier.

With the aid of such a spray boom, different fluids can be supplied to a surface to be cleaned or in a container interior to be cleaned. For example, it is provided that a cleaning fluid, for example a mixture of water and cleaning agent, is made available at the first input connection, while a rinsing fluid, for example water, is made available at the second input connection. The nozzle carrier can be equipped with different spray nozzles, each of which is adapted to the fluid made available at the corresponding inlet connection. In addition or as an alternative, provision can also be made to provide the same fluid at both input connections and to use only the properties of the possibly differently designed spray nozzles which are assigned to the first input connection or the second input connection. In particular, it can be provided that a time sequence of the provision of fluid at the first inlet connection and at the second inlet connection is specified in order to be able to produce specific cleaning effects.

The possibility of rotating the nozzle carrier in relation to the outer tube ensures an advantageous cleaning effect, since the spatial alignment of the spray nozzles, which are arranged on the nozzle carrier and assigned to the respective nozzle channels, can be changed in the course of the rotational movement.

It is preferably provided that at least two spray nozzles received on the nozzle carrier are assigned to the first input connection and / or the second input connection.

Advantageous further developments of the invention are the subject of the dependent claims.

It is useful if the first fluid channel is designed as a bore in the inner shaft. This allows a space-saving fluid supply from the first inlet connection to the first nozzle channel to be implemented.

It is preferably provided that the inner shaft is provided with at least one first transverse bore, preferably arranged opposite the first input connection, aligned transversely to the first axis of rotation, which is fluidically connected to the first fluid channel. In this way, a structurally simple supply of fluid starting from the first input connection into the bore of the inner shaft is achieved. If a pulsating fluid flow is desired, it can be provided that there is a fluidically communicating connection between the first input connection and the bore in the inner shaft only when the transverse bore is opposite the first input connection. If, on the other hand, a continuous flow of fluid from the first inlet connection into the bore of the inner shaft is desired, a circumferential recess in the manner of a circumferential groove, which is also referred to as an annular groove, on the inner shaft and / or a circumferential recess in the manner of a circumferential groove, which is referred to as an annular groove will be provided on an inner wall of the outer tube in the area of the first input connection and the transverse bore in the inner shaft.

In a further development of the invention it is provided that the inner shaft is non-rotatably connected to a coupling body and that the nozzle carrier is rotatably mounted on the coupling body about a second axis of rotation, the first axis of rotation and the second axis of rotation enclosing an angle between 90 degrees and 180 degrees, as well with a gear device which is designed to couple the movement of the nozzle carrier with the outer tube. Due to the rotatable mounting of the nozzle carrier on the coupling body, the nozzle carrier can perform a rotational movement around the second axis of rotation when the inner shaft and the coupling body coupled to it rotate, this rotational movement of the nozzle carrier possibly being independent of the rotational movement of the coupling body around the first axis of rotation. For example, it can be provided that the spray nozzles are aligned on the nozzle carrier in such a way that a torque is exerted on the nozzle carrier during a spraying process, so that the nozzle carrier is set into a rotational movement around the second axis of rotation solely by the spraying process. Alternatively, a forced coupling can be provided between the nozzle carrier and the outer tube, whereby when the coupling body rotates about the first axis of rotation, an inevitable rotational movement of the nozzle carrier takes place both about the first axis of rotation and about the second axis of rotation and thus there is a superposition of two rotational movements for the nozzle carrier , with which it can be ensured that the fluid emerging from the spray nozzles can advantageously be distributed in a large volume of space.

It is advantageous if a first connection channel for connecting the first fluid channel in the outer tube to the first nozzle channel of the nozzle carrier is formed in the coupling body and if a second connection channel is formed in the coupling body for connecting the second fluid channel in the outer tube to the second nozzle channel of the nozzle carrier. This enables a compact design of the spray boom, since the fluid provided at the first inlet connection and the fluid provided at the second inlet connection are not only guaranteed within the outer tube and the nozzle carrier, but also within the coupling body.

In a further embodiment of the invention it is provided that a sleeve body which is rotationally symmetrical to the first axis of rotation is received in the outer tube, which has a longitudinal bore extending along the first axis of rotation which delimits the second fluid channel at least in sections with an outer wall of the inner shaft. The sleeve body thus serves to delimit the second fluid channel, but can also be provided with bearing means and / or sealing means, for example to ensure a fluid-tight separation from the first inlet connection and the first fluid channel and also to ensure the rotatable mounting of the inner shaft with respect to the outer tube. For example, it is provided that the sleeve body is mounted in an opening of the outer tube facing away from the drive housing, in particular is screwed there.

It is preferably provided that the sleeve body is provided with at least one second transverse bore, which is preferably arranged opposite the second input connection, is oriented transversely to the first axis of rotation and is fluidically communicating with the second fluid channel.

It is useful if a circumferential gear, in particular configured as a bevel gear, is configured on an end face of the sleeve body. This gearwheel, together with a toothing formed on the nozzle carrier, forms a transmission device with which a movable positive coupling can be implemented between the outer tube and the nozzle carrier. The alignment of the first axis of rotation and the second axis of rotation as well as the design of the gear on the sleeve body and the toothing on the nozzle carrier are matched to one another in such a way that the toothing on the nozzle carrier engages the gear wheel on the sleeve body at exactly one point and thus a Rolling movement of the teeth on the nozzle carrier takes place in relation to the gear on the sleeve body.

In an advantageous development of the invention, it is provided that the coupling body has a bearing stub aligned coaxially to the second axis of rotation, on which the nozzle carrier is rotatably mounted, the bearing stub having a plurality of annular grooves aligned coaxially to the second axis of rotation, which are used for receiving sealing means and / or bearing means are trained. The bearing socket thus serves, on the one hand, for the rotatable mounting of the nozzle carrier on the coupling body, bearing means such as ball bearings or sliding bearings being received in one or more of the annular grooves of the bearing socket. In addition, the annular grooves make it possible to achieve a seal between the bearing support and the nozzle carrier, which is important in particular with regard to the fluid supply between the inlet connections and the nozzle channels.

It is advantageous if a first spray nozzle is accommodated in the first nozzle channel of the nozzle carrier and if a second spray nozzle is accommodated in the second nozzle channel of the nozzle carrier, the first spray nozzle having a smaller length and / or a smaller spray opening than the second spray nozzle. Due to the geometrically different design of the first spray nozzles and the second spray nozzles, a first fluid that is provided at the first inlet connection can be sprayed in a different manner than a second fluid that is provided at the second input connection.

One in the Figures 1 to 3 The first exemplary embodiment shown of a spray device 50 is designed for cleaning a container interior with preferably two different fluids, for example with cleaning foam as the first fluid and water as the second fluid.

The spray device 50 comprises according to FIGS Figures 1 to 3 a drive device 1, which has a drive not shown in detail in the drawings, in particular designed as an electric motor with a downstream gear, which is received in a drive housing 21 shown only in sections. The spray device 50 further comprises a spray boom 3 coupled to the drive housing 21.

The drive housing 21 and an outer tube 14 of the spray boom 3 of the spray device 50 are firmly connected to one another, for example the spray boom 3 is inserted at the end into an axially aligned recess 10 in the drive housing 21 and secured with a screw connection not shown in detail. By way of example, the spray boom 3 is designed for attachment to a container wall 51, which is only shown schematically in dashed lines. For this purpose, for example, a circumferential annular collar (not shown) can be formed on the hollow-cylindrical outer tube 14 of the spray boom 3, which can be used as a fastening flange to screw the spray boom 3 to the container wall 51 by means of fastening screws not shown in detail.

The drive device 1 comprises a drive shaft 20, designed for example as a transmission output shaft of an electric geared motor, which according to the illustration of FIG Figures 1 and 2 in the vertical direction protrudes downwards and which is designed to provide a rotational movement about a first axis of rotation 22, as well as a coupling 2 arranged at the end of the drive shaft 20, which is implemented, for example, as a claw coupling with a coupling element (not shown) made of an elastic material, in particular as an elastomer coupling, accommodated between opposing claw assemblies can be.

In the outer tube 14 of the spray boom 3, an inner shaft 15 is rotatably mounted about the axis of rotation 22, which is coupled non-rotatably to the drive shaft 20 by means of the coupling 2. The inner shaft 15 is traversed in sections by a first fluid channel 16, which extends along the first axis of rotation 22 between first transverse bores 17, which are made in the inner shaft 15 transversely to the first axis of rotation 22 adjacent to the drive device 1, and one at the end, remote from the drive device 1 arranged mouth opening 18 extends.

In the area of the first transverse bores 17, a circumferential first annular channel 19 is formed in the outer tube 14, which ensures a fluidically communicating connection between a first inlet connection 23 of the outer tube 14 and the first transverse bores 17 and the first fluid channel 16.

At an end region of the outer tube 14 facing away from the drive 1, a sleeve body 5, which is embodied in a purely exemplary manner to be rotationally symmetrical to the first axis of rotation 22, is received in the outer tube 14. The sleeve body 5 is non-rotatably connected to the outer tube 14 and is penetrated by a longitudinal bore 24 which extends along the first axis of rotation 22 and in which the inner shaft 15 runs in sections. On a frontal In the end region of the sleeve body 5, a gear 25, designed in the manner of a bevel gear, is integrally formed, which protrudes slightly over the outer tube 14. Furthermore, a sealing ring 9 is provided between the inner shaft 15 and the sleeve body 5 in order to ensure a fluid-tight mounting of the inner shaft 15 with respect to the sleeve body 5, at least in sections.

The inner shaft 15 is rotatably supported and sealed in the outer tube 14. For this purpose, slide bearings 11, 12 are arranged between the outer tube 14 and the inner shaft 15. Furthermore, sealing rings 13 are provided between the outer tube 14 and the inner shaft 15 in order to ensure, at least in sections, a fluid-tight mounting of the inner shaft 15 with respect to the outer tube 14.

A coupling body 35 and a nozzle carrier 30 attached to it are arranged on an end region of the outer tube 14 facing away from the drive device 1. Here, the coupling body 35 is coupled to the inner shaft 15 in a rotationally fixed manner by means of a connection section 61.

The nozzle carrier 30 is provided on a purely exemplary flat top side 31 with an edge-side, radially outwardly arranged, circular circumferential toothing 32, which is designed for engagement with the gear 25 of the sleeve body 5. With a rotational movement of the nozzle carrier 30 about the first axis of rotation 22, which can be caused by a rotation of the inner shaft 15 and the coupling body 35 connected to it in a rotationally fixed manner, the toothing 32 of the nozzle carrier 30 rolls off on the gear 25 of the sleeve body 5, resulting in a Rotational movement of the nozzle carrier 30 about a second axis of rotation 33 results, which is oriented purely by way of example at an angle 60 of 135 degrees with respect to the first axis of rotation 22. For this purpose, the first nozzle carrier 30 is mounted on the coupling body 35 such that it can rotate about the second axis of rotation 33.

The coupling body 35 is penetrated by a first connecting channel 38, which is at least partially aligned coaxially to the first axis of rotation 22 and is in fluidically communicating connection with the first fluid channel 16. Furthermore, the first connection channel 38 runs in sections coaxially to the second axis of rotation 33 and is fluidically communicating with second transverse bores 39 at an end region facing away from the inner shaft 15, which in turn are introduced into the coupling body 35 transversely to the second axis of rotation 33.

Like depicting the Figure 1 can be removed, extend in the nozzle carrier 30 starting from an annular channel 40, which is arranged radially circumferentially in the area of the second transverse bores 39 of the coupling body 35, obliquely to the second axis of rotation 33 in the radial direction outwardly extending first nozzle channels 41, which in first nozzle receptacles 42 flow out. First spray nozzles 43 are screwed into each of the first nozzle receptacles 42, which are designed purely by way of example as threaded bores and have spray openings (not shown). A first fluid, in particular liquid, can emerge from the spray openings, which is provided at the first inlet connection 23 of the outer tube 14 and can be conducted to the nozzle receptacles 42 via the first fluid channel 16 and the first connecting channel 38 and the first nozzle channels.

By way of example, the coupling body 35 has a first annular, in particular flat, cut surface 36 which is arranged opposite a flat end face 6 of the sleeve body 5. Between the cut surface 36 and the flat end face 6 of the sleeve body 5, a circular ring-shaped, only schematically illustrated, ring-shaped slide bearing 7 is formed, which is used for the rotatable support of the coupling body 35 on the sleeve body 5. In an outer region of the first cut surface 36, a circumferential groove 37 is made, into which the gear 25 of the sleeve body 5 protrudes freely.

Between a second, flat cut surface 101 facing the nozzle carrier 30 and the oppositely arranged top side 31 of the nozzle carrier 30, a further annular sliding bearing 8 is arranged, which is designed for a rotatable mounting of the nozzle carrier 30 with respect to the coupling body 35.

Due to the interaction of the toothing 32 of the nozzle carrier 30 with the gear wheel 25, when the inner shaft 15 rotates relative to the outer tube 14, a rotational movement of the nozzle carrier 30 about the first axis of rotation 22 is superimposed with a rotational movement of the nozzle carrier 30 about the second axis of rotation 33, whereby a first fluid emerging from the first spray nozzles 43 can be sprayed in a space volume not shown in detail.

Furthermore, a second inlet connection 44 is formed on the outer tube 14, which allows a second fluid to be fed into a second annular channel 45 formed between the outer tube 14 and the sleeve body 5. The second ring channel 45 stands with third transverse bores 46, which are made in the sleeve body 5 transversely to the first axis of rotation 22, in fluidly communicating connection with an extending along the first axis of rotation 22 between an inner wall 47 of the sleeve body 5 and an outer wall 49 of the inner shaft 15 to the coupling body 35, second fluid channel 48 designed as an annular channel.

Like depicting the Figure 2 which shows the spray device 50 in a second rotational position for the nozzle carrier 30, the nozzle carrier 30 has second nozzle channels 54 which run parallel to the second axis of rotation 33 and are, for example, designed as cylindrical bores. The second nozzle channels 54 each open into second nozzle receptacles 55 in which second spray nozzles 56 are received. The second spray nozzles 56 are designed in several parts, purely by way of example, and are longer than the first spray nozzles 43.

In order to ensure a fluidically communicating connection between the second fluid channel 48 and an annular groove 53 formed in the nozzle carrier, several second connecting channels 58, 59 designed as bores are formed in the coupling body 35, one of the connecting channels 58 being straight and one of the connecting channels 59 being purely exemplary is angled. Furthermore, the annular groove 53 is in fluidic communication with the nozzle channels 54, so that a fluid provided at the second inlet connection 44 can be conducted through the outer tube 14 to the coupling body 35 and from there via the nozzle carrier 30 to the second spray nozzles 56.

When the inner shaft 15 rotates relative to the outer tube 14, the rotational movement of the nozzle carrier 30 about the first rotational axis 22 is superimposed for the second spray nozzles 56 in the same way with the rotational movement of the nozzle carrier 30 about the second rotational axis 33, whereby one from the second spray nozzles 56 emerging second fluid can be sprayed in a space volume not shown in detail.

Like depicting the Figure 4 can be removed, the coupling body 35 has, purely by way of example, a base body 100 designed as a hemispherical section, from which the bearing stub 62, which is coaxially aligned with the second axis of rotation 33 and designed for the rotatable mounting of the nozzle carrier 30, projects. For this purpose, the bearing stub 62 is provided with a plurality of annular grooves 63, 64 aligned coaxially to the second axis of rotation 33, which are designed to accommodate sealing means 102 or bearing means 103, as shown in the representations of FIG Figures 1 and 2 are recognizable.

In the Fig. 5 and Fig. 6 a second embodiment of a spray device 65 is shown by way of example, which is designed for surface cleaning. The spray device 65 has a simplified structure compared to the spray device 50, since no complex superimposition of rotational movements is required for surface cleaning.

In the case of the spray device 65, an outer tube 66 is fixed to a drive housing 67. In the drive housing 67, a drive motor, not shown in detail, which can be an electric geared motor, for example, is received. A drive shaft 68 of the drive motor is rotatably mounted about a first axis of rotation on the drive housing 67 and is in a rotationally fixed connection via a coupling with an inner shaft 71 which is rotatably mounted in the outer tube 66. The inner shaft 71 is non-rotatably coupled to a nozzle carrier 72, which is rotatably mounted on an end face 73 of the outer tube 66 facing away from the drive housing 67. For this purpose, annular sealing arrangements 75, 76 and 77 are arranged between the end face 73 of the outer tube 66 and an opposite end face 74 of the nozzle carrier 72, concentric to one another and coaxially to the first axes of rotation 69.

A first input connection 78 and a second input connection 79 are formed on the outer tube 66. The first input connection 78 is designed to provide a first fluid to the nozzle carrier 72, while the second input connection 79 is designed to provide a second fluid to the nozzle carrier 72. For a fluidically communicating connection between the first inlet connection 78 and the nozzle carrier 72, a first fluid channel 90, in particular designed as a longitudinal bore parallel to the first axis of rotation 69, is introduced into the outer tube 66. For a fluidically communicating connection between the second inlet connection 79 and the nozzle carrier 72, a second fluid channel 91, in particular designed as a longitudinal bore parallel to the first axis of rotation 69, is introduced into the outer tube 66.

A first, radially inner annular groove 81 and a second, radially outer annular groove 82, which are in fluidic communication with the first longitudinal bore 81 and the second longitudinal bore 82, are made in the end face 74 of the nozzle carrier 72 opposite the outer tube 66. Starting from the first annular groove 81, a first nozzle channel 83 extends to a first nozzle receptacle 85, in a first spray nozzle 87 is added. Starting from the second annular groove 82, a second nozzle channel 84 extends as far as a second nozzle receptacle 86, in which a second spray nozzle 88 is received.

When the inner shaft 71 rotates relative to the outer tube 66 and a first fluid is supplied to the first input connection 78 and a second fluid to the second input connection 79, the first fluid is sprayed through the first spray nozzles 87 and the second fluid is sprayed through the second spray nozzles 88 , with which the first fluid and the second fluid can be introduced into a space region which is purely exemplary in the shape of a cone segment and can be applied over a circle, for example, to a surface oriented perpendicular to the axis of rotation 69.

The following text comes from the registration DE 10 2019 002 183.5 and is included in the present application documents to maintain priority.

The invention relates to a device for cleaning, spraying, rinsing, applying or drying in the interior or on surfaces of containers, pipe and plant systems for receiving and transporting liquid, steam, gaseous and pulpy media of all kinds such as food, chemicals, building materials and others, for example in the food industry, in the chemical and construction industries as well as in the medical field.

From the patent specification DE 199 38 435 C2 a cleaning device for containers or the like with a spray head and a bearing part is known on which the spray head is rotatably held by means of a bearing, with between the Bearing part and the spray head a spacing space is arranged, which is in spatial connection with the environment, and wherein the spray head has at least one spray nozzle, the rinsing liquid can be supplied by means of a detergent supply line, and wherein the spacing space is in spatial connection with the detergent supply line, characterized in that, that the bearing part has a holding piece which holds rotatably in the bearing part by means of the mounting of a bevel gear connected non-rotatably to the spray head, that the holding piece has an end surface which is arranged parallel to and spaced apart from an end surface of the spray head to form the spacing space, that the end surface of the spray head covers the connection point formed between the holding piece and the bearing part, that the holding piece has an external thread on its outer circumference with which it is screwed into an internal thread of the bearing part, that the end surface of the spray head has the weight Inde connection covers, and that the bearing part has an annular circumferential surface following the threaded connection, which is at a distance from the end surface of the spray head and which together with this end surface forms part of the spacing space.

The object of this invention was to create a cleaning device which is characterized by a high level of operational reliability.

The company Peter MOOG & CIE AG, 73076 Worb, Switzerland, also produces a large number of cleaning systems that are used in the high pressure area, such as the patent CH 704 093 B1 .

This patent discloses a device for cleaning internal surfaces of containers, in particular barrels or tanks, by means of at least one fluid jet of fluids impinging on the internal surfaces, with a first fluid path which extends from a fluid inlet of the device through the device to at least one nozzle hole having nozzle area of the device extends; a second fluid path, which extends from a suction region of the device having at least one suction hole through the device to a fluid outlet of the device.

The fluid outlet is to be arranged outside of the container to be cleaned; and the nozzle area and the suction area of the device are to be arranged in the interior of the container to be cleaned; characterized in that an energy source providing energy can be connected to the fluid inlet; that during the cleaning operation of the device with a connected fluid source, both the flow energy of a fluid jet emerging from a nozzle hole and the suction energy at a suction hole are provided by the fluid source connected to the fluid inlet; and that the nozzle area is formed by at least one nozzle hole, preferably a plurality of nozzle holes having nozzle head, which is rotatably mounted in the first fluid path in a multi-axis manner and which is driven in rotation thanks to the energy of the fluid coming from the connectable fluid source. The problem with the known systems is that they are only ever designed for one activity, for example cleaning, rinsing or drying. If another medium is to be used, the device must first be cleaned and the nozzles replaced, or other devices must be used.

It was therefore the object of the invention to create a device for cleaning, spraying, rinsing, applying and drying in the interior as well as surfaces of containers as well as pipe and plant systems for receiving and transporting liquid, vaporous, gaseous and pulpy media of all kinds, in which the device within a housing can be used with at least two different media one after the other without the media in the same housing being able to influence each other or cleaning work having to be carried out in between, with which the cleaning effort is optimized and the associated downtimes are reduced as far as possible.

The object is achieved with the features of claim A, characterized in that the device has at least two separate media access points within the housing, a sleeve body which is mechanically fixed to the inner wall of the housing and a hollow drive spindle rotating vertically in the center of the sleeve body The first media access is equipped with a separate first channel in the rotating drive spindle and the second media access is equipped with a second annular channel in the wall of the fixed sleeve body, both of which are separately connected to one another via a rotating base body and a rotating nozzle holder with different nozzles via a cover connect are.

The construction, according to claim B, is characterized in that in the order the first media access into the central first channel of the hollow drive spindle, into the rotating base body, the rotating nozzle holder and in this separate and symmetrical branching off from the first channel into two separate channels opens into various first threaded openings arranged in the nozzle holder the first nozzle is led to the outside and the second media access into the, between the hollow drive spindle and the housing, into the second separate annular channel of the sleeve body, through the rotation base body into a groove arranged at the end of the nozzle holder, into two separate symmetrically vertically branching off from the groove Channels opens and is guided to the outside via second threaded openings arranged separately in the nozzle holder in second nozzles.

It is advantageous, according to claim C, that the housing is mechanically firmly connected to the housing of the drive in the vertical direction on the one hand and is rotatably guided centrally and vertically in the housing on the other hand via the coupling with the hollow drive spindle and the cylindrical sleeve body between the housing and the hollow drive spindle is equipped with a ring-shaped gear wheel formed in one piece at the end and mechanically firmly connected to the inner wall of the housing.

It should be emphasized here that the described arrangement makes it possible to absolutely avoid a connection between the separate media access points with the channels that are separately assigned to them and the different nozzles. The linear rotary movement of the drive is transmitted via the coupling to the hollow rotating drive shaft on the rotating base body and the 3-D movement from this to the subsequent rotating nozzle holder and the nozzles attached to it.

It is also advantageous to mention the structural design of the functionally relevant parts, according to claims 4 to 6, which, if necessary, also allow more than two different media with separate accesses, channels and to use the required nozzles for various processing operations in all types of indoor spaces. This leads to a considerable time saving in the work processes and cost savings for the previously required acquisition of a large number of devices and wear parts to be replaced.
