Description

Technical Field

[0001] This invention relates to a tank cleaner, particularly a track-mounted cleaner, for cleaning tanks. The tank cleaner includes: a static body having a housing having an upper housing portion and a lower housing portion configured for connection to a supply line receiving cleaning fluid; a rotating body mounted on the static body about a main rotation axis; a gear mechanism including a gear assembly having a main input shaft and a main output shaft, the main output shaft extending beyond the housing and configured to drive the rotating body about the main rotation axis; and a drive device coupled to the main input shaft for driving the main input shaft under the driving action of the received cleaning fluid. Background Technology

[0002] In the field of tank cleaning, particularly in industrial and commercial environments, tank cleaners that utilize rotary nozzles to deliver high-pressure cleaning fluids are commonly employed. These devices are crucial for maintaining the hygiene and operational efficiency of tanks used to store a wide variety of substances, including food, chemicals, and pharmaceuticals. Known systems typically involve a combination of static and rotating components driven by fluid pressure to achieve the desired cleaning effect, as shown in DE 10 2019 005 830 A1. The rotary nozzle is usually powered by a drive unit and gear mechanism that interact to convert fluid pressure into rotational motion.

[0003] While these tank cleaners are effective, several challenges remain. For example, the assembly and maintenance of these cleaning devices can be complex and time-consuming due to the intricate arrangement of the static body, which includes gears and drives housed at least partially within the housing forming the static body. According to known designs, components are often arranged in a manner requiring precise alignment, specialized tools for adjustment, and multiple fixed steps, which can lead to higher labor costs. Furthermore, the combination of the drives and gears within the cleaning device's housing is often not optimized for ease of assembly and maintenance. This can result in difficulty accessing and repairing internal components, further complicating the maintenance process. Additionally, the correct arrangement and alignment of these components are crucial for the reliable operation of the cleaning device but cannot be inspected without disassembling the entire static body assembly. Misalignment or improper securing of the gears and drives can lead to mechanical failure and increased wear on components.

[0004] Despite significant advancements in can cleaning technology, improved systems are still needed to address these challenges. Specifically, there is a need for can cleaners that offer simplified and safer assembly and the ability to check the alignment and positioning of all components.

[0005] Therefore, the fundamental technical problem of the present invention is to provide a tank cleaning device that at least partially overcomes the shortcomings of known systems. Summary of the Invention

[0006] The object of this invention is to provide a tank cleaner that overcomes one or more of the disadvantages of known systems.

[0007] According to a first aspect of the invention, these objectives are achieved by a can cleaner according to the invention.

[0008] The cleaner includes a static body with a housing comprising an upper housing portion and a lower housing portion configured for connection to a supply line receiving cleaning fluid. A rotating body, rotating about a main axis of rotation, is mounted on the static body. A gear mechanism—characterized by a gear assembly having a main input shaft and a main output shaft extending beyond the housing—is configured to drive the rotating body about the main axis of rotation. The drive mechanism is operatively coupled to the main input shaft, enabling the main input shaft to be driven by the received cleaning fluid. The rotating body driven by the gear mechanism provides thorough and uniform cleaning coverage within the tank, thus solving the challenge of reaching all internal surfaces. The main input and main output shafts of the gear assembly can be precisely aligned to ensure efficient power transmission, reduce wear, and extend the cleaner's lifespan. The drive mechanism, powered by the cleaning fluid, eliminates the need for an external power source, simplifying the cleaner's design and operation. This configuration also improves the cleaner's reliability, as it relies on a continuous flow of cleaning fluid to function. In summary, the described can cleaner provides a compact, efficient, and reliable solution for maintaining can cleanliness, especially in industrial environments where thorough and continuous cleaning is critical.

[0009] The present invention addresses the initially stated objective by proposing a stacking device formed by stacking at least one component of the gear assembly and multiple components of the drive assembly together along the main axis of rotation in a predetermined order. The components in the stacking device support each other in the radial direction, thereby ensuring radial alignment of the stacking device. The stacking device allows components to be mounted in a housing for assembly such that each component is axially positioned and radially supported. Assembly can be performed without special tools, thus simplifying the process. The components of the stacking device support each other, and no support structures or other installation tools are required. Therefore, the stacking device allows the drive and gear assemblies to be removed from the housing portion of the static body without requiring specially fitted tools or damaging any of its components. However, tools may be needed to separate two or more housing portions of the static body.

[0010] Therefore, in the context of this invention, a stacking device refers to a device formed by stacking multiple components, particularly three or more components, onto each other along a main axis of rotation in a stacking direction, wherein each component is supported by contacting the facing surface or edge of another component in the stacking device, thereby enabling support in the stacking direction and defining a predetermined position for each component in the axial direction. Thus, to disassemble such a stacking device, it is only necessary to lift the components from the stacking device against the stacking direction. Therefore, the stacking direction defines the direction along the main axis of rotation, in which the components of the gear mechanism and drive mechanism are stacked from the base of the stacking device to the top of the base device. Radial support in the stacking device is provided by form-fitting engagement between the components of the stacking device, which is achieved by stacking the components in the stacking direction without any support structure outside the stacking device. Therefore, such a stacking device allows the components forming the stacking device to be assembled one after another, or by selectively stacking individual components or pre-collection devices. The pre-collection device can be, for example, a gear carrier having multiple gears mounted to it. It should be understood that the operational connection of the drive mechanism and gear mechanism is achieved independently of the stacking.

[0011] In other words, the present invention proposes forming a stacking device comprising gear mechanisms and drive mechanisms arranged in a stacking assembly, wherein the stacking assembly is formed by stacking the components along a main axis of rotation in a stacking direction such that the components of the gear mechanisms and drive mechanisms are fixed in the radial direction by engaging with the shape of at least one component within the stacking assembly, but remain movable against the stacking direction to allow for disassembly of the stacking assembly. Thus, each component of the stacking assembly is supported in both the radial and axial directions by one or more components of the remaining portion of the stacking assembly. Specifically, this support prevents any radial or axial displacement of the components within the stacking assembly relative to each other. However, it should be understood that, in particular, the rotating components of the gear mechanisms and drive mechanisms may experience slight axial or radial displacement during rotational movement due to unbalanced support of the respective components. Furthermore, additional fixing mechanisms to prevent displacement of the components of the stacking assembly against the stacking direction can be used for axial fixation and are within the scope of the present invention.

[0012] Other embodiments of the invention are given in other aspects, which further develop the concept of the invention in the context of the object of the invention with respect to advantageous features and additional advantages.

[0013] Preferably, the stacking device is capable of collecting components that are at least partially located outside the housing. In particular, the stacking of components requiring specific alignment verification is facilitated to be performed outside the housing, wherein other components of the stacking device can be stacked inside the housing and guided to their desired positions by the corresponding housing portions of the static body.

[0014] According to an embodiment, a stacking device for can cleaners, particularly a track-mounted cleaner for cleaning cans, includes at least one end body designed to define a planar base region facing the remainder of the stacking device. During assembly, the base region is the surface on which the stacking device is stacked. The end body ensures that the components of the stacking device are supported axially by the planar base region facing the remainder of the stacking device. Specifically, the surface of the end body opposite the base region is also planar, allowing for the creation of a solid foundation on a conventional surface that is also typically planar. This allows for precise alignment of components, thereby facilitating the correct transmission of mechanical forces and rotational motion from the drive unit to the gear mechanism and ultimately to the rotating body. By defining the planar base region, the end body also helps reduce the possibility of misalignment or uneven wear, which can improve the durability and operational efficiency of the can cleaner. Furthermore, in the installed state of the stacking device in the installed can cleaner, the planar base region can be oriented upwards or downwards, thus providing flexibility in component design. When the planar base region is oriented upwards in the installed state, the stacking device is stacked in an inverted manner.

[0015] According to another embodiment, the drive unit includes at least one stator and / or at least one impeller. More preferably, the stator defines an end body forming a planar base region. Preferably, the planar base region is oriented upward when the stacking assembly is received in the housing in the installed state of the can cleaner. The planar upper surface of the stator facing the remainder of the stacking assembly serves as a base element within the stacking assembly, forming the base region when the stacking assembly is being stacked but not yet inserted into the housing. The planar base region of the stator provides a stable and flat joint that facilitates the precise stacking of subsequent components, such as gear mechanisms, thereby improving the overall structural integrity and operational efficiency of the can cleaner. By defining the base region, the stator helps to distribute mechanical loads and stresses evenly across the stacking assembly, thereby reducing the likelihood of misalignment or mechanical failure.

[0016] According to another embodiment, the stacking assembly is axially fixed by a gear mechanism. Therefore, the axial positioning of the stacking assembly remains stable, thereby enhancing the overall structural integrity of the stacking assembly and the operational reliability of the tank cleaner. The axial fixing mechanism provided by the gear mechanism prevents any axial displacement of components within the stacking assembly, which could otherwise lead to misalignment or operational inefficiency. Specifically, the stacking assembly is axially fixed by a plug-in connector that fixes the gear assembly to the drive unit. More preferably, the gear assembly engages with the stator via a plug-in connector. This establishes a direct mechanical fixation in the axial direction between the two components. The interaction between the gear mechanism and the stator contributes only to the stability of the stacking assembly, as the stator and gear mechanism provide two opposing supports in the axial direction, thus providing robust axial fixation for the stacking assembly.

[0017] According to another embodiment, the gear assembly includes a fixed gear that engages with the main output shaft. This engagement preferably ensures that rotational motion generated by a drive mechanism coupled to the main input shaft and driven by the received cleaning fluid is effectively transmitted to the main output shaft and further to a nozzle carrier driven by the fixed gear. The engagement of the fixed gear with the main output shaft contributes to the stable and continuous transmission of torque. Furthermore, the fixed gear defines a stop shoulder for supporting the stacking assembly. This stop shoulder provides axial support for the stacking assembly, which includes gear assemblies and drive mechanisms arranged in a predetermined order and fixed in the radial direction. By defining the stop shoulder, the fixed gear ensures that the components within the stacking assembly are precisely aligned and held in their designated positions, while allowing the output shaft to extend beyond the stacking assembly to engage with the nozzle carrier, for example, through a recess provided in the lower housing portion. By holding the components of the stacking assembly in their designated positions, the rotational motion of the output shaft is not impeded.

[0018] According to another embodiment, the stacking device includes an enclosure portion configured to receive a drive unit therein, particularly a stator and / or impeller. Therefore, a dedicated enclosure portion is provided within the stacking device for housing the drive unit. Thus, the drive unit, including the stator and / or impeller, is securely housed within this enclosure portion. By housing the stator and / or impeller within the enclosure portion, this design contributes to a more compact and organized assembly structure, thereby reducing the risk of misalignment or mechanical interference between components. This configuration also helps protect the drive unit from external contaminants and mechanical damage, potentially increasing the lifespan and reliability of the tank cleaner. Furthermore, the enclosure portion contributes to the overall structural integrity of the stacking device by providing additional support and rigidity. Radial fixation further ensures that components remain fixed in their designated positions, thereby minimizing the risk of lateral displacement that could lead to operational inefficiency or mechanical failure.

[0019] According to another embodiment, the tank cleaner includes a containment portion that includes an internal stop member. This internal stop member is specifically configured to axially support the stator and / or impeller. By providing axial support, the internal stop member ensures that these components remain securely in place during operation of the tank cleaner. Both the stator and impeller benefit from this axial support, as the impeller interacts with the cleaning fluid to generate the necessary driving force. The internal stop member mitigates the risk of axial displacement or misalignment, which could otherwise lead to inefficient operation or mechanical failure. By ensuring that the stator and impeller are axially supported within the containment portion, this design simplifies the assembly process and reduces the likelihood of assembly errors. This, in turn, contributes to the overall reliability and user-friendliness of the tank cleaner, making it a more robust and reliable solution for tank cleaning applications.

[0020] According to another embodiment, a tank cleaner, particularly a track-mounted cleaner for cleaning tanks, is enhanced by incorporating a sealing portion configured as a ring gear. This ring gear engages with a gear assembly and is configured to radially support the gear assembly. Specifically, the sealing portion configured as a ring gear is the same sealing portion used to receive the drive unit as described above. The ring gear, meshing with the gear teeth of the gear assembly, facilitates the transmission of rotational motion from the drive unit to the rotating body. The engagement of the ring gear with the gear assembly ensures that rotational force is effectively transmitted and distributed, thereby improving the stability and efficiency of gear operation. The radial support provided by the ring gear is crucial for maintaining the alignment and integrity of the gear assembly, especially under dynamic operating conditions where the cleaning fluid drives the main input shaft. This radial support reduces the possibility of gear misalignment or displacement, which could otherwise lead to inefficient operation or mechanical failure. Furthermore, the configuration of the ring gear as a sealing portion adds an extra layer of protection to the gear assembly, thus protecting it from external contaminants and mechanical damage. In addition, the combination of the ring gear along the main axis of rotation within the stacking device highlights the compact and efficient design of the tank cleaner, resulting in a streamlined component that is both space-saving and easy to maintain.

[0021] According to another embodiment, the stop shoulder is a first stop shoulder. The first stop shoulder serves as an initial contact point and support point within the assembly. Furthermore, the enclosure portion is designed to define a second stop shoulder, which provides additional axial support for the stacking assembly. The second stop shoulder serves as a secondary stabilizing point. This dual stop shoulder configuration enhances the stability of the stacking assembly during stacking. The presence of these stop shoulders facilitates easier assembly and maintenance of the tank cleaner, as the components can be precisely positioned and locked in place without the need for complex adjustments.

[0022] According to another embodiment, the enclosure portion is configured to radially align the drive unit. The enclosure portion serves as a critical intermediate component, ensuring precise radial positioning of the drive unit relative to the main axis of rotation. In doing so, the enclosure portion facilitates seamless and stable interaction between the drive unit and the gear unit, which are configured in a stacked arrangement along the main axis of rotation. The radial alignment provided by the enclosure portion mitigates any potential misalignment problems that may occur during stacking. This feature also simplifies the assembly and maintenance process, as it provides a clear and unambiguous structure for positioning the drive unit, making it easier for technicians to assemble and repair the tank cleaner. Furthermore, the enclosure portion is preferably configured to radially align the gear unit. Therefore, the enclosure portion ensures precise radial positioning of both the gear unit and the drive unit relative to the main axis of rotation, as well as precise radial positioning between them.

[0023] According to another embodiment, the stacking device includes a spacer arranged axially relative to the main axis of rotation between the fixed gear and the enclosure portion. The spacer serves to maintain a defined distance between the fixed gear and the enclosure portion, thereby preventing any undesirable axial movement that could lead to wear or misalignment over time. This axial arrangement contributes to the stability and durability of the gear assembly by ensuring that the components remain securely in place during assembly and operation. Furthermore, the stacking device is reinforced by placing the spacer between a first stop shoulder and a second stop shoulder. This specific positioning provides an additional layer of mechanical stability by creating a defined boundary within which the spacer operates. The first and second stop shoulders act as physical barriers restricting the axial movement of the spacer, thereby ensuring that the spacer remains in the correct position relative to the fixed gear and the enclosure portion.

[0024] According to another embodiment, the stacking device is configured to be inserted as a whole into an upper or lower housing portion. The stacking device, including a gear assembly and a drive mechanism, is designed to be pre-assembled and then inserted into the housing portion as a single unit. This modular approach simplifies the installation process because it eliminates the need to assemble the gear assembly and drive mechanism separately within the housing. The gear assembly, including a gear assemblies with a main input shaft and a main output shaft, and the drive mechanism coupled to the main input shaft, are aligned in a predetermined sequence. This alignment ensures that the components are correctly positioned relative to each other and relative to the main axis of rotation. Correct arrangement can be easily ensured by visually inspecting the stacking device or its components from the outside of the housing. The stacking device is then inserted into the housing portion, where it is fixed radially. This fixing prevents any lateral movement of the stacking device, thereby ensuring that the components remain in their correct position during operation. This new feature of being able to insert the stacking device as a whole reduces the time and effort required for assembly, resulting in increased efficiency in the manufacturing process. Furthermore, it simplifies maintenance and repair because the stacking device can be easily removed and replaced as a single unit. This modularity allows for faster troubleshooting and replacement of faulty parts, thereby minimizing downtime and maintenance costs.

[0025] According to another embodiment, the drive unit is operatively coupled to the gear assembly via a form-fit engagement. Form-fit engagement facilitates simpler and more efficient assembly and disassembly processes, which is particularly beneficial for maintenance and repair operations, while ensuring a precise and robust transmission mechanism to transfer rotational force from the drive unit to the gear assembly. By using form-fit engagement, the need for complex tools and procedures for connecting or disconnecting the drive unit from the gear assembly is significantly reduced, thereby minimizing downtime and labor costs. Furthermore, this type of connection ensures a safe and reliable transmission of driving force from the drive unit to the gear assembly, which is crucial for the continuous and efficient operation of the rotating body around the main axis of rotation. The engagement of the form-fit engagement also conforms to the stacked arrangement of the gear assembly and drive unit along the main axis of rotation, thereby ensuring that the components are fixed in both the axial and radial directions. This alignment and fixation contribute to the overall stability and balance of the tank cleaner.

[0026] According to another embodiment, the can cleaner, particularly the track-mounted cleaner, is enhanced by including a housing with at least one alignment region designed to have an inner diameter corresponding to the outer diameter of one or more components of the stacking assembly. This alignment region ensures precise and secure positioning of the components within the housing, thereby enhancing the overall stability and functionality of the can cleaner. Specifically, the alignment region is configured to correspond to the outer diameter of the enclosure portion and / or the outer diameter of the spacers, and / or the outer diameter of the stationary gear. The enclosure portion, a critical component of the stacking assembly, benefits from this alignment by ensuring that the components are securely housed and preventing any lateral movement that could interfere with the operation of the can cleaner. Similarly, spacers used to maintain the correct distance between the various components within the stacking assembly are also securely positioned via the alignment region, thereby ensuring that the spatial configuration of the components is maintained as designed. Furthermore, the stationary gear associated with the gear assembly is also securely positioned via the alignment region. These components share the characteristic that they are unaffected by any rotational movement, and thus allow for radial alignment of the stacking assembly as a whole within the housing. Specifically, the components of the stacking device having an outer diameter corresponding to the inner diameter of the alignment area are defined by at least one fixing member that does not involve any rotational movement, the at least one fixing member being used to radially align the stacking device in the housing.

[0027] According to a second aspect, the present invention addresses the initially stated objective through a static body assembly according to the invention. Specifically, the invention provides a static body assembly comprising a static body having a housing, the housing including an upper housing portion and a lower housing portion configured for connection to a supply line receiving cleaning fluid. This configuration ensures a robust and efficient connection to the fluid supply line, thereby facilitating the inflow of cleaning fluid into the system. Additionally, the static body assembly includes a gear mechanism comprising a gear assembly having a main input shaft and a main output shaft extending beyond the housing. A drive mechanism is coupled to the main input shaft, which is driven by the received cleaning fluid, thereby converting the kinetic energy of the fluid into mechanical energy to drive the cleaning process. The gear mechanism and drive mechanism are configured to form a stacking arrangement by stacking at least one component of the drive mechanism and multiple components of the gear mechanism in a predetermined order along the main axis of rotation. In the stacking arrangement, the components support each other in the radial direction, thereby ensuring alignment of the stacking arrangement in the radial direction. By having the stacking arrangement, the static body assembly enjoys the benefits described with respect to the first aspect of the invention. Therefore, the benefits and preferred embodiments of the first aspect of the invention are also the benefits and preferred embodiments of the second aspect of the invention.

[0028] According to a third aspect, the invention addresses the initially stated objective through a method according to the invention for installing a tank cleaner, particularly a track-mounted cleaner. The method first provides a static body comprising a housing having an upper housing portion configured for connection to a supply line receiving cleaning fluid and a lower housing portion. This initial step establishes the necessary foundation for subsequent assembly. Following this, the method requires stacking gear mechanisms and drive mechanisms together to form a stacked assembly. The gear mechanism includes a gear assembly having a main input shaft and a main output shaft, the main output shaft extending beyond the housing and configured to drive the rotating body about a main axis of rotation. Specifically, the stacked assembly is formed by stacking components of the drive mechanism and gear mechanism in a predetermined order along the main axis of rotation in a stacking direction, thereby fixing the components radially. Optionally, the method further includes axially fixing the stacked assembly, particularly by means of plug-in connectors capable of axially fixing the drive mechanism and gear mechanism to prevent axial displacement relative to each other, where axial displacement could lead to disassembly of the stacked assembly. The drive mechanism is preferably operatively coupled to the main input shaft. This connection is achieved, in particular, by stacking components together during the formation of the stacking assembly, enabling the drive unit to drive the main input shaft when driven by the received cleaning fluid. The connection mechanism is preferably of the form-fit type and ensures that the driving force from the cleaning fluid is effectively transmitted to the gear mechanism, thereby facilitating the rotation of the rotating body. The stacking assembly is carefully stacked along the main axis of rotation in a predetermined order and fixed in the radial direction, ensuring that the components are aligned and stable during operation. The method also includes inserting the stacking assembly, preferably fixed in the axial direction, into the upper or lower housing portion according to design and assembly requirements. In this regard, the gear mechanism and drive unit are inserted into one of the upper and lower housing portions while the stacking assembly has already been formed. Alternatively, the components of the gear mechanism and drive unit are inserted into one of the upper and lower housing portions respectively and stacked therein to form the stacking assembly. This insertion step facilitates the formation of a static body assembly that defines a static body with a housing in which the gear mechanism and drive unit are received. Alternatively, the stacking assembly can be at least partially stacked within the upper or lower housing portion. Once the stacking assembly is in place, the method involves closing the upper and lower housing portions to secure the internal components and protect them from external elements. Finally, the method includes mounting a rotating body, which rotates about a main axis of rotation, onto a static body. This final step completes the assembly, resulting in a fully functional tank cleaner capable of efficient and effective cleaning operations. By assembling the stacking assembly, the method enjoys the benefits described with respect to the first aspect of the invention. Therefore, the benefits and preferred embodiments of the first aspect of the invention are also the benefits and preferred embodiments of the third aspect of the invention.

[0034] Figure 4 A flowchart illustrating a method for assembling a static body assembly is shown. Detailed Implementation

[0035] Figure 1a The illustration shows a can cleaner 1 designed for cleaning cans, specifically a track cleaner 2.

[0036] The tank cleaner 1 includes a static body assembly 3a, a rotating body 4, and a nozzle carrier 8. The static body assembly 3a includes a static body 3 and... Figure 2 and Figure 3 The stacking device 9 is shown in the figure.

[0037] The static body 3 includes a housing 30 having an upper housing portion 31 and a lower housing portion 32. The upper housing portion 31 is configured for connection to a supply line 6 for receiving cleaning fluid. The upper housing portion 31 facilitates connection to the supply line 6, thereby ensuring that cleaning fluid is directed into the housing 30 for subsequent use in the cleaning process.

[0038] The rotating body 4 is mounted on the static body 3 and rotates about the main rotation axis R1. The rotating body 4 is connected by a gear mechanism 10 (see...). Figure 1b ) and drive unit 7 (see Figure 1b The rotating body 4 is driven about the main rotation axis R1. This rotational capability allows the rotating body 4 to perform cleaning operations within the tank by distributing cleaning fluid in a controlled manner. The rotating body 4, mounted on the static body 3, rotates about the main rotation axis R1, while the nozzle carrier 8, supported by the rotating body 4, rotates about the secondary rotation axis R2.

[0039] The tank cleaner 1 also includes a plurality of nozzles 82 mounted on a nozzle carrier 8, which is driven about a secondary rotation axis R2 and supported by a rotating body 4. The nozzles 82 are strategically positioned to guide the cleaning fluid within the tank, thereby ensuring thorough cleaning.

[0040] Figure 1b A cross-sectional view of the can cleaner 1 is provided, which details the internal components and their configuration.

[0041] The drive unit 7 includes a stator 71 and an impeller 72, preferably housed within the enclosure portion 94. The stator 71 may define an end body 91 disposed on top of the stacking assembly, such as... Figure 2 As shown in the image.

[0042] The gear mechanism 10 includes a gear assembly 11 configured as a planetary gear 12 having a main input shaft 120 and a main output shaft 130. The gear assembly 11 is configured to drive the rotating body 4 about the main rotation axis R1.

[0043] The drive unit 7 is specifically operatively connected to the main input shaft 120 via a form-fit engagement and is responsible for driving the main input shaft 120 using the force provided by the received cleaning fluid. This connection allows the cleaning fluid to power the gear unit 10, which in turn drives the rotating body 4, thereby ensuring the effective transmission of stationary and rotational forces.

[0044] The drive unit 7 is axially fixed to the gear assembly 11 via a plug-in connector 73, thereby ensuring the axial fixation of the stacking device 9.

[0045] The main output shaft 130 extends beyond the housing 30 and is configured to drive the rotating body 4 about the main rotation axis R1. This arrangement ensures that the rotational motion necessary for cleaning is transmitted from the gear assembly 11 to the rotating body 4.

[0046] The main output shaft 130 also engages with a fixed gear 160, thereby facilitating the rotation of the nozzle carrier 8 about the secondary rotation axis R2. The fixed gear 160 defines a stop shoulder 161 that supports the stacking device 9.

[0047] Additionally, the spacer 96 is axially positioned between the fixed gear 160 and the enclosure portion 94. The enclosure portion 94 is constructed as a ring gear 95, which engages with the gear assembly 11 and provides radial support for both the gear assembly 11 and the drive unit 7.

[0048] The housing 30 has at least one alignment region 33, the inner diameter di of which corresponds to the outer diameter do of the sealing member, such as the sealing portion 94, the spacer 96, and the fixed gear 160.

[0049] For assembly, the gear assembly 10 and the drive unit 7 are designed to rotate along the main rotation axis R1. Figure 2 and Figure 3 The predetermined sequence shown is arranged in the stacking device 9. The stacking device 9 is fixed in the radial direction R, thereby ensuring that the components remain correctly aligned and work synergistically to facilitate the cleaning process inside the tank.

[0050] Figure 2 and Figure 3 An exploded view is shown, detailing the stacking device 9 along the main rotation axis R1, in which... Figure 2 The stacking device 9 is shown in a three-dimensional view and Figure 3 The stacking device 9 is shown in a side view. Identical or similar components are present. Figure 1a , Figure 1b , Figure 2 and Figure 3 The same reference numerals are used in the accompanying drawings, and the description above is also provided.

[0051] The stacking device 9 consists of a drive device 7 and a gear device 10, and is preferably designed to be inserted as a whole into the upper housing portion 31 or the lower housing portion 32, thereby facilitating assembly and maintenance.

[0052] from Figure 2 and Figure 3 Starting from the left side, the drive unit 7 includes a stator 71, which is coupled to the left side of the drive unit 7. Figure 1b The end body 91, which is arranged on top of the stacking device 9 in the installed state shown, defines the base region 93 of the stacking device 9 during assembly (see [reference]). Figure 2 Therefore, stacked component 9 is relative to Figure 1b The installation configuration shown is preferably achieved by stacking the components in an inverted manner.

[0053] The stator 71 is connected to the main input shaft 120 via a plug-in connector 74, thereby defining a plug-in connector 73 to facilitate axial fixation of the drive unit 7 to the gear assembly 10. Adjacent to the stator 71 is an impeller 72, which is also part of the drive unit 7. The impeller 72 is responsible for converting the received clean fluid into mechanical energy to drive the main input shaft 120. This rotational motion driving the main input shaft 120 is transmitted via a form-fit engagement between the impeller 72 and the main input shaft 120. The impeller 72 has a recess 75, and the main input shaft 120 has a mating outer contour 121 that engages with the recess 75 of the impeller 72. The impeller 72 is supported in the direction of the main rotation axis R1 by resting its contact surface facing the gear assembly 11 on a support surface 122 of the gear assembly 11 associated with the main input shaft 120.

[0054] The next component in the stacking device 9 is the enclosure portion 94 configured as a ring gear 95. The ring gear 95 engages with the gear assembly 11 to provide radial support.

[0055] The gear assembly 10, including the gear assembly 11, will now be described. The gear assembly 11 includes a main input shaft 120 and a main output shaft 130. The main input shaft 120 is driven by the drive unit 7, while the main output shaft 130 extends beyond the housing 30 (see [link to description]). Figure 1a , Figure 1b ) to drive the rotating body 4 around the main rotation axis R1 (see Figure 1a , Figure 1b ).

[0056] A fixed gear 160, which is part of the gear assembly 10, engages with the main output shaft 130. The fixed gear 160 defines a stop shoulder 161 that supports the stacking assembly 9.

[0057] The enclosure portion 94 also has an internal stop member 94a that axially supports the stator 71 and / or impeller 72. Additionally, the enclosure portion 94 defines a second stop shoulder 97, thereby further supporting the stacking device 9.

[0058] Additionally, the stacking device 9 includes a spacer 96 axially positioned between the fixed gear 160 and the enclosure portion 94, specifically between the first stop shoulder 161 and the second stop shoulder 97 defined by the enclosure portion 94. The spacer 96 ensures proper axial alignment and spacing within the stacking device 9.

[0059] In summary, the stacking device 9 is precisely laid out along the main rotation axis R1. A drive unit 7, including a stator 71 and an impeller 72, initiates mechanical motion, which is then transmitted via a gear mechanism 10, comprising a gear assembly 11 with a main input shaft 120 and a main output shaft 130. A sealing portion 94, configured as a ring gear 95, together with spacers 96, ensures proper alignment and support within the stacking device 9. A fixed gear 160 provides additional axial support via its stop shoulder 161, thereby achieving... Figure 2 The assembly structure described.

[0060] The overall design of the can cleaner 1 provides a robust and effective solution for can cleaning applications through its stacking device 9 and combined gear device 10 and drive device 7.

[0061] Figure 4 The description is of a tank cleaner 1, specifically based on Figure 1a and Figure 1b The flowchart of method 1000 for cleaning the canister.

[0062] In the first step 1100 of method 100, a static body 3 is provided, the static body 3 having a housing 30 having an upper housing portion 31 and a lower housing portion 32 configured for connection with a supply line 6 for receiving clean fluid.

[0063] In the second step 1200, method 1000 includes stacking the gear assembly 10 and the drive unit 7 together to form a stacked assembly 9, specifically stacking each component of the gear assembly 10 and the drive unit 7 one after another, and optionally also including pre-assembled components to form the stacked assembly 9.

[0064] Gear assembly 10 preferably according to Figure 2 and Figure 3The design includes a gear assembly 11 having a main input shaft 120 and a main output shaft 130 extending beyond the housing 30, and a drive unit 7 is coupled to the main input shaft 120 for driving the main input shaft 120 under the driving action of the received cleaning fluid. In the second step 1200, the stacking device 9 is formed by stacking components of the drive unit 7 and the gear assembly in a predetermined order along the main rotation axis R1 in a stacking direction, thereby fixing the components in the radial direction R. Optionally, method 1000 further includes axially fixing the stacking device 9, particularly by means of a plug-in connector 93. The plug-in connector 93 is implemented between a plug 94 and the input shaft 120, wherein the plug 94 rests against a surface of the stator 71 opposite to the rest of the stacking device 9. Thus, the plug 94 axially fixes the drive unit 7 and the gear assembly 10 against each other, thereby providing axial fixation of the stack.

[0065] The third step 1300 of method 1000 includes inserting the gear assembly 10 and the drive assembly 7 into one of the upper housing portion 31 and the lower housing portion 32. In a first alternative, the gear assembly 10 and the drive assembly 7 are inserted into one of the upper housing portion 31 and the lower housing portion 32 while the stacked assembly 9 has already been formed. Alternatively, the gear assembly 10 and the drive assembly 7 are at least partially and individually inserted into one of the upper housing portion 31 and the lower housing portion 32 and stacked therein to form the stacked assembly 9.

[0066] Next, in the fourth step 1400, the upper housing portion 31 and the lower housing portion 32 are closed.

[0067] In the fifth step 1500, method 1000 includes mounting a rotating body 4, which rotates about the main rotation axis R1, onto a static body 3.

[0068] Preferably, method 1000 includes, in a sixth step 1600, mounting a nozzle carrier 8 having one or more nozzles 82 to the rotating body 4, wherein the nozzle carrier 8 is mounted to engage with the gear mechanism 10, particularly with the fixed gear 160, so as to be driven about the secondary rotation axis R2.
