EP3464164B1 - Device for filling tanks, comprising an intermediate container - Google Patents

Description

The present invention relates to a device for filling tanks and in particular for filling tanks without contamination. Such a device is, for example, from WO 2014/005951 A1 known. The present invention is also aimed in particular at a device, for example, for transferring liquid plant protection products from small containers, such as canisters or bottles, into other larger containers, such as barrels or tanks. Corresponding devices are generally known from the prior art, but they have not yet allowed cleaning of internal valve components. Those described in the above WO 2014/005951 The device described already allows valve components to be flushed.

Systems for hermetically dispensing and diluting concentrated chemicals from a container into a dilution tank are also known. An example of such a device is from US 5,062,459 B1 known. This device comprises a first part which is arranged in a first container. This part includes a valve that allows the concentrate to be directed into a measuring container. A second section is connected to a pressurized water source. The second section includes several valves, which can be used to control the concentrate from the measuring container into the dilution tank. Another valve is used to direct water from the pressurized water source through the device and the measuring container into the dilution tank.

However, the prior art has shown that metering the liquids to be filled or checking the transferred liquids is often difficult to achieve. The complete removal and cleaning of the devices known from the prior art is also difficult.

The present invention is therefore based on the object of providing such a device for decanting liquids, which enables the decanted volumes to be checked and also offers improved handling of such measuring devices. These tasks are achieved according to the invention by the subject matter of claim 1. Advantageous embodiments and further developments are the subject of the subclaims.

A device according to the invention for filling tanks is characterized by the features of claim 1. Such a device for filling tanks, for example from a canister, has a first adapter device which is suitable and intended for at least temporary attachment to the canister and which has a feed device via which a flowable medium can be guided from the canister into the tank. Furthermore, the device has a detergent connection in order to supply a cleaning liquid to at least one component of the device. However, a permanent attachment to the canister would also be conceivable. According to the invention, the device has a further receptacle for temporarily holding the flowable medium to be filled into the tank as well as a cleaning device for cleaning this receptacle, this cleaning device having at least one detergent channel which has a line of Cleaning liquid from the detergent connection to the receptacle allows. The device preferably also has a second adapter device, which is suitable for at least temporary (but also permanent) and indirect attachment to the tank and/or the receptacle.

An additional receptacle is therefore proposed within the scope of the present invention, which - as mentioned above - can be used for interim storage the liquid to be filled is used. This receptacle can also enable measurement of the liquids to be decanted. The device advantageously has a filling opening provided with a valve, through which the product can be filled.

In a further advantageous embodiment, the device has a tank adapter which is used for attachment to a tank. The device advantageously has a first coupling part. Particularly preferably, said tank adapter has a tank fastening flange for fastening to the tank.

In particular, in an open position, the device provides a fluid connection between a canister fastening means, in particular a canister fastening flange, and the tank fastening means, in particular a tank fastening flange, and in a closed position closes the fluid connection between the canister fastening flange and the tank fastening flange.

By accommodating the flushing connection on the second adapter device, i.e. on the tank adapter, it is possible to flush the connection area between the tank adapter and the canister adapter both when the canister is completely emptied and when part of it is removed.

Providing the flushing connection on the tank adapter also has the advantage that the canister adapter has a correspondingly lower weight. This in turn simplifies handling for the user, as he usually first screws the canister adapter onto the canister and then couples this unit of canister and canister adapter with the tank adapter. Within the scope of the invention, it is also conceivable that the canister adapter is an integral part of the canister. It is therefore advantageous if the canister adapter is constructed as cost-effectively as possible.

In a further advantageous embodiment, the feed device is designed as a canister adapter and this canister adapter preferably also has a canister fastening flange for attachment to a canister. In addition, a second coupling part can also be provided. The above-mentioned first coupling part and the second coupling part can preferably be connected to one another or separated from one another. With others In other words, said tank adapter and the canister adapter are preferably releasably connected to one another via the first and second coupling parts.

The above-mentioned valve of the device preferably allows, in an open position, a fluid connection between the canister adapter or the canister fastening flange and the tank fastening adapter or the tank fastening flange. In a closed position of this valve, this fluid connection between the canister attachment adapter and the tank attachment adapter is preferably closed.

In a further advantageous embodiment, said first and second coupling parts can establish a first fluid connection between the canister fastening flange and the tank fastening flange in an open position of the valve or the device, as well as a second lockable fluid connection between the detergent connection and the canister adapter.

By attaching the flushing connection to the tank adapter, a possibility is opened up to flush a connection area between the tank adapter and the canister adapter in different operating situations, for example when the canister is completely emptied but also when a part is removed.

According to the invention, it is provided that the cleaning device for cleaning the receptacle has at least one outlet element, which is aligned in such a way that cleaning liquid emerging from this outlet element reaches an inner wall of the receptacle. In this way, efficient cleaning of the receptacle or its inner wall is possible. In a further advantageous embodiment, the at least one outlet element is designed such that the cleaning liquid reaches an upper edge of the inner wall of the receptacle. Gravity allows the liquid to flow downwards and in this way essentially clean the entire surface of the receptacle.

In a further advantageous embodiment, the cleaning device has a second outlet element, which is aligned in such a way that cleaning liquid emerging from this second outlet element also hits the inner wall of the receptacle reached. It is therefore possible for both the first outlet element and the second outlet element to direct the cleaning liquid - but preferably at different points - onto the receptacle. In this way, complete cleaning of the receptacle can be made easier.

In an advantageous embodiment, the two outlet elements are arranged opposite one another. For example, it is possible for the outlet elements to direct the cleaning liquid to areas of the receptacle which are arranged opposite one another or which are offset from one another by a circumferential angle of 180°. In addition, it would also be possible for more than two outlet elements to be provided. However, said outlet elements are advantageously distributed evenly in the circumferential direction of the device, regardless of their number.

In a further advantageous embodiment, the cleaning device has at least one outlet element, which is aligned in such a way that cleaning liquid emerging from this second outlet element also exits at least in a direction tangential to the circumferential direction of the receptacle. The receiving container is therefore preferably acted upon in a direction which has both a radial component and a tangential component. This procedure allows the cleaning liquid to be specifically applied to the receptacle or its inner wall and in this way to be distributed very evenly on the inner surface of the receptacle. In this way, very efficient cleaning of the receptacle is possible.

For example, it is possible for the liquid to reach the receptacle in such a way that the liquid runs or flows downwards in a spiral, even under the influence of gravity.

The receptacle advantageously has a rotationally symmetrical shape and in particular a circular or conical shape.

In a further advantageous embodiment, the outlet elements are arranged such that the cleaning liquid is directed at an angle onto the inner wall, which deviates from the tangential direction by less than 20°, preferably less than 15° and preferably less than 10°.

The cleaning liquids advantageously emerge from the two outlet elements in opposite directions. In this way, it can be achieved that the cleaning liquid emerging from the two outlet elements is applied to the containers in the same direction of rotation or in the same tangential direction. For example, it can be achieved that the cleaning liquid drains clockwise or counterclockwise relative to the receptacle or its wall.

In a further advantageous embodiment, at least one outlet element is designed as an outlet nozzle. This outlet element is advantageously spaced at least slightly from the inner wall of the container. The at least one outlet element is advantageously aligned in such a way that the cleaning liquid hits the inner wall of the receptacle without significant splashing.

In a further advantageous embodiment, at least one outlet element projects into the receiving container. This outlet element can preferably have a detergent channel which extends essentially in the tangential direction of the receptacle. However, the cleaning liquid advantageously emerges from the outlet element within the receptacle. The liquid preferably emerges in a horizontal direction.

In a further advantageous embodiment, the detergent channel, which supplies the detergent to the outlet elements, is designed at least in sections as an annular channel. In this way, it is possible for the detergent to be guided, for example, via a laterally arranged detergent channel and, starting from this, to be guided via an annular channel to the at least one outlet element and preferably to both outlet elements. In this way, uniform exposure to different areas of the receptacle is possible.

In a further advantageous embodiment, the valve for supplying the liquid to the tanks also has a closing piston.

According to the invention, the device has a ventilation device for ventilating and/or venting this receptacle. In this embodiment, the fact can be taken into account in particular that an undesirable negative pressure may arise from forwarding the liquid from this receptacle into the tank. The ventilation device therefore preferably serves to ventilate the receptacle.

The device preferably has a drainage device in order to drain away excess medium.

In this embodiment according to the invention, it is proposed that a protective mechanism is preferably present which comes into force when, for example, during a filling process a lot of medium is supplied. It is particularly conceivable that in the event of excess pressure excess liquid and especially excess water is drained away. This diverting device preferably serves to direct excess medium out of the device and in particular excess liquid medium.

In an advantageous embodiment, this diverting device has a first valve device, which is suitable and intended to cause a liquid medium to be drained out of the device by opening (this valve device). It is conceivable that this valve device is closed in a normal state, but if excess pressure occurs, it opens and in this way the liquid medium is drained from the device.

This first valve device is preferably designed as a check valve. This means that above a certain excess pressure, this valve device opens and ensures that excess liquid can be drained out.

Particularly preferably, a valve position of this first valve device can be changed by an excess pressure arising in the receptacle and/or the filling canister. It is possible for this first valve device to be triggered pneumatically, that is, by air pressure, or hydraulically, that is, by liquid pressure. In particular, said first valve can be moved from a closed to an open position by the excess pressure. In a normal state, this first valve is preferably closed. This means that during normal operation no liquid is drained through this valve.

Through the procedure described here, an internal pressure in the receiving container or the measuring cup can be limited, so that no damage can occur to either the receiving element or the canister. In a further advantageous embodiment, a hose connection is provided for draining away liquid and in particular water. This means that a hose can be connected to the device, with which water can also be specifically drained into a desired area.

This first valve, which is particularly preferably designed as an overflow valve, opens at a certain pressure and limits the internal pressure so that no damage occurs.

In the event that the receptacle is completely or completely filled with liquid medium or only partially and an excess pressure then arises, it is also possible that contaminated liquid can flow away. It is therefore preferred that a hose system or an overflow hose be discharged without resistance into another device such as a sprayer or an induction hopper or a container.

In a further advantageous embodiment, said diverting device has a second valve device. This second valve device is preferably a further rollover valve, which serves in particular but not exclusively for the purpose of preventing liquid from pulsating in the discharge line. This second valve device is preferably arranged in a section of the diverter device. In a further preferred embodiment, the device has a hose adapter.

In a further advantageous embodiment, the ventilation device has a valve device which controls an air flow between the receptacle and the environment.

This valve device can be set in such a way that ventilation only occurs from a certain negative pressure in the receptacle.

In a further advantageous embodiment, this valve device is designed as a check valve. This valve device can advantageously have a spring-loaded valve body which forces the valve into a closed position. This valve body can be arranged in such a way that, from a certain negative pressure, air can enter the receptacle, but no air or excess pressure can be removed via this valve device.

This valve therefore only opens advantageously above a certain negative pressure.

Advantageously, said valve body can be moved in a longitudinal direction, this longitudinal direction also being in particular a longitudinal direction of the receiving container or a main flow direction of the liquid to be filled into the tank. In particular, this is a vertical or essentially vertical direction.

In a further advantageous embodiment, the ventilation device allows air to be supplied into the receptacle and blocks air from being discharged from the receptacle. In a further advantageous embodiment, the valve housing is made of plastic.

Particularly preferably, the ventilation device and/or a valve device of the ventilation device is arranged laterally on a support of the device. In a further advantageous embodiment, the ventilation device has at least one air duct which extends in a straight line at least in sections. In particular, this air duct extends through a housing and/or in a radial direction of the device. It is also possible here for this air duct to be designed at least in sections as an annular duct.

In a further advantageous embodiment, said valve device of the ventilation device is designed as a float valve. It is therefore conceivable that this valve device has a hollow ball, which is preferably in an open position when the receptacle is unfilled. Ventilation is possible in this position. In other words, air can flow in here freely and in this way the canister can be prevented from collapsing due to negative pressure.

If the receptacle is overfilled, the ball floats on the liquid medium and preferably closes against a sealing seat. In this case the medium cannot escape any further. However, it is still ensured that excess air can escape. In a further advantageous embodiment, the ventilation device can also be operated manually and in particular can be closed. So that large containers can also be sucked out with the hose adapter, the air flow can also be interrupted by pressing a button. In this case, negative pressure, which is necessary for suction, can build up. However, an adjusting device is still provided, which causes this writing or button device to open automatically after the negative pressure in the entire system has been reduced. For this purpose can For example, a biasing means such as a spring can be provided, which causes the button and thus also the valve to open after the negative pressure has been reduced.

In a further advantageous embodiment, a connecting channel is provided which connects the overflow valve and/or the ventilation valve to an interior of the receiving container. It is conceivable that the same channel establishes both the flow connection between the overflow valve and the flow connection between the ventilation valve and the interior of the receptacle. This connecting channel preferably has a cross section that is larger than. In this way it is possible to reduce the flow resistance for the air and thus also the maximum achievable negative pressure during suction. The same applies to the outflowing water in the event of excess pressure.

The two valves mentioned are preferably arranged next to one another, in particular on an outside of the device.

In a further advantageous embodiment, the device has a measuring device for determining the quantity of the liquid to be filled into the tank. For example, a flow measuring device could be provided which determines a flow of the liquid. However, the further receptacle is advantageously designed as a measuring device for determining the quantity of the liquid to be filled into the tank, or this receptacle has such a measuring device. For example, it is possible for this receptacle to be transparent and, for example, to have a scale on one wall for measuring the liquid in the container or its quantity.

The device preferably has a measuring device which is suitable and intended for determining the quantity of the liquid to be filled into the tank. Furthermore, the device additionally has a display device, by means of which at least a spatial positioning of at least one component of the device can be determined and in particular readable. In this embodiment according to the invention, it is therefore proposed that not only the amount to be filled can be determined but also a positioning of at least one component of the device and in particular of the receptacle. This takes into account the fact that filling often takes place under conditions in which the receptacle is not upright and the measurement results are therefore distorted. The additional display device ensures that a safe and realistic reading of the measuring device is possible.

The positioning of the component of the device is preferably a pivoting position and in particular a pivoting position in space. The respective pivot position of the device can therefore preferably be detected by means of the display device. In a preferred embodiment, the receptacle is at least partially and preferably completely transparent. In this case, it is possible to detect, in particular, a fill level of a substance and in particular liquid located inside the receptacle through a wall of the receptacle. The measuring device preferably has a measuring scale. This measuring scale is particularly preferably arranged in a transparent area.

This is preferably a measuring scale that enables linear reading. In a further preferred embodiment, the receptacle expands in one direction, for example it can enlarge or expand conically from bottom to top.

In a further advantageous embodiment, the display device allows the spatial position to be determined with respect to at least two pivot axes and preferably with respect to at least two mutually perpendicular pivot axes. In this way, it can be determined in particular whether and, if necessary, when the receptacle is aligned exactly vertically in a preferred position, for example.

In a further advantageous embodiment, the display device is arranged on a surface of the device that is arranged horizontally during operation. In this way, particularly convenient and safe reading is achieved. For example, the device can have a fastening flange, by means of which, for example, the receptacle is fastened to other components. This receiving flange can have the said horizontal surface, on which the display device is arranged.

In a further advantageous embodiment, the display device has a cavity filled with a liquid. This is advantageously a closed cavity. An air bubble or other suitable float element may be located within this cavity.

In a further advantageous embodiment, the display device is a so-called dragonfly. This level is preferably movable not only along one direction, but preferably within a plane, so that, as mentioned above, a pivot position can be determined with respect to two mutually perpendicular pivot axes. In this way, an alignment with respect to two axes can be carried out in a particularly simple manner using the spirit level.

In a further advantageous embodiment, the measuring device has a readable measuring scale. The display device is advantageously arranged in such a way that the display device and the readable measuring scale can be observed at the same time.

In a further advantageous embodiment, the device has a cleaning device for cleaning this receptacle, which preferably has at least one detergent channel which carries a line of cleaning liquid from the detergent connection to the receiving container. In this way it is possible to clean the receptacle in a particularly simple manner.

In a further advantageous embodiment, the cleaning device has at least one outlet element, which is aligned such that cleaning liquid emerging from this outlet element reaches an inner wall of the receptacle.

The above-mentioned display device serves in particular, but not exclusively, to reduce a dosing error that can occur due to a misalignment of the receptacle or cup.

In a further advantageous embodiment, the receptacle has a funnel-shaped section. In a further advantageous embodiment, a further valve device can also be arranged between the receptacle and the tank. In this way, the receptacle can first be filled with a certain amount of liquid and then this amount can be drained into the tank. In this way it can be ensured that only a precisely defined amount of liquid enters the tank. This can be particularly helpful if several liquids are to be mixed together in one tank.

In a further advantageous embodiment, the receiving container has fastening means for fastening to the tank. This can in particular be a thread or the like.

In a further advantageous embodiment, the further receptacle is made of a plastic. The receptacle advantageously allows the accommodation of a larger volume of liquid like other areas of the device and in particular like other lines that lead from the canister adapter to the receptacle. As mentioned above, the further receptacle is preferably designed to be rotationally symmetrical.

In a further advantageous embodiment, the receptacle is arranged downstream of the feed device in a flow direction of the liquid to be filled into the tank. This means that the liquid from the tank first reaches the receptacle via the adapter devices and can be drained from there into a tank.

In a further advantageous embodiment, the device has a valve device which is arranged between the receptacle and the tank to be filled. This valve device can be connected directly to the receptacle. This valve device can preferably be operated manually. When the valve device is closed, the receptacle can be filled with liquid, the amount of liquid filled being able to be determined, for example, using the scale above. This valve device can then be opened to allow the measured liquid to flow into the tank. It is possible for a channel for guiding the liquid to be connected to this valve device.

The receptacle is also advantageously arranged downstream of the flushing connection. Particularly preferably, the receptacle has a peripheral edge, in particular a peripheral edge, with which it can be flanged to an adapter element.

In a further advantageous embodiment, sealing devices can be provided between the coupling elements, such as O-rings or the like. For example, a sealing element can be arranged on the first or second coupling part.

In a further advantageous embodiment, a valve element is arranged in the adapter device, which is used to arrange it on the canister, and in particular a closing piston, which is preferably adjustable via an actuating element between an open position and the closed position. This closing piston can have an inner channel which, in the open position of the device, provides a second fluid connection, for example between the flushing connection and the canister fastening connection. In addition, this canister adapter can have an outer channel arranged around this closing piston have, which in the open position creates part of a fluid connection between the canister and the tank or the canister and the further receptacle.

According to a further embodiment, the first and second coupling parts are designed such that, in the open position of the device, they provide a first fluid connection between the canister fastening flange and the tank fastening flange and a second, lockable fluid connection between the flushing connection and the canister fastening flange.

For the fluid-tight connection of the tank adapter and canister adapter, at least one sealing element can be provided on the first or second coupling part. According to a further embodiment of the invention, a closing piston is guided in the canister adapter and can be adjusted between the open position and the closed position via an actuating element. This closing piston can have an inner channel which, in the open position of the device, provides the second fluid connection between the flushing connection and the canister fastening flange. Furthermore, the canister adapter can have an outer channel arranged around the closing piston, which in the open position forms part of the first fluid connection between the canister fastening flange and the tank fastening flange.

Furthermore, the closing piston can have a first contact surface which is in operative contact with a second contact surface provided on the tank adapter when the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter. According to a preferred embodiment of the invention, it is provided that the inner channel of the closing piston opens at one end into the first contact surface and is connected at its other end to the canister fastening flange and the tank adapter has a closable connecting channel which has one end in the second contact surface and is connected at its other end to the flushing connection, the connecting channel opening into the second contact surface and the inner channel of the closing piston opening into the first contact surface being connected to one another when the tank adapter and the canister adapter are connected to one another via the two contact surfaces be in contact. It is expedient if at least one seal is provided between the two contact surfaces.

According to a further embodiment, the closing piston is guided in a link guide on the canister adapter, with a rotation of the canister adapter causing a displacement of the closing piston relative to the canister adapter. Furthermore, it can be provided that the second coupling part of the tank adapter is rotatably mounted on the tank adapter with an actuating element. In a further embodiment, the first contact surface of the closing piston is in non-rotatable contact with the second contact surface on the tank adapter when the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter (i.e. the second adapter device), with a subsequent rotation of the second coupling part relative to the Tank adapter causes a displacement of the closing piston relative to the canister adapter (i.e. the first adapter device.

Furthermore, it is advantageously provided that the first contact surface of the closing piston is in contact with the second contact surface on the tank adapter when the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter, and wherein the second contact surface is mounted on the tank adapter so as to be displaceable in the direction of movement of the closing piston and a spring element presses the second contact surface against the first contact surface. The displacement or lifting of the second contact surface from the first contact surface can be carried out by a further actuating element, while the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter. In this way, additional rinsing or cleaning of the two contact surfaces is possible with a cleaning liquid supplied via the rinsing connection.

Canisters, especially those containing pesticides, are sealed with a sealing film in the area of the outlet before first use. Such sealing films are often removed by the user by hand, whereby skin contact with the fluid or with a protective glove can easily occur. In a preferred embodiment of the invention, the canister adapter is therefore provided in the area of the canister fastening flange with an integrated film cutting element for cutting open the sealing film of the canister. The film cutting element can be formed by a toothed ring, in particular aligned obliquely to the longitudinal central axis of the canister adapter. Furthermore, the canister adapter can have a sliding sleeve to which the canister fastening flange is attached, the sliding sleeve being axially displaceable relative to the film cutting element.

Thanks to the integrated film cutting element, the user does not have to remove the sealing film himself, but simply screws the canister adapter onto the outlet opening of the canister using the fastening flange. Either the sealing film is automatically cut open by this screwing-in process or it is only opened after it has been screwed on by bringing the film cutting element into contact with the sealing film by means of the sliding sleeve in order to open it.

According to the invention, the device has a cleaning device in order to clean this receptacle, as well as at least one outlet element which supplies a rinsing medium to the receptacle. In this embodiment, it is therefore proposed that cleaning of the receptacle in question is also possible.

In a preferred embodiment, this application device is in flow connection with the detergent connection via a connecting line. It is possible for this connecting line to branch off from the said detergent connection. For example, a tea piece or a piece of trousers can be provided, which enables the connecting line to be branched off from the detergent connection. In this way, a cleaning medium for cleaning the receptacle can be supplied directly above the detergent connection.

According to the invention, the outlet element is arranged such that cleaning liquid emerging from this outlet element reaches an inner wall of the receptacle.

According to the invention, the outlet element is arranged such that liquid emerging from it creates a vortex within the receptacle.

It is generally recommended that the system be cleaned after measuring the liquid medium. It is also possible and preferred for the canister to be cleaned, in particular using a canister adapter. Rinsing nozzles are preferably provided for cleaning the receptacle, and as mentioned above, these can be attached, for example, below the flanges. Due to their special arrangement, these nozzles preferably create a vortex that cleans the receptacle within a short time.

In a further advantageous embodiment, the outlet element has a predetermined flow cross section which is selected such that, at least during the cleaning process, more liquid flows into the receptacle than cleaning liquid flows out. In other words, a cross section of these loading elements or nozzles in particular is designed such that more water flows into the cup than can flow out. In this way, the vortex in question also builds up to the tank adapter mentioned above. This makes it possible in particular for the entire receptacle and also a predetermined area or in particular a lower part of the tank adapter to be cleaned.

To supply the said loading elements or flushing nozzles, a channel can be provided, which is arranged in particular in the connecting flange. This channel in turn can also be connected to the tank flange. Starting from the flushing connection of the tank flange, fresh water can be diverted downwards into the receptacle.

In a further advantageous embodiment, said connecting line therefore runs at least in sections through a fastening flange which serves to fasten the feed device to the receptacle. This connecting line advantageously runs through both of the connecting flanges mentioned.

In a further advantageous embodiment, said connecting line runs in a straight line and particularly preferably in a vertical direction through the connecting flange.

In a further advantageous embodiment, the device has at least two outlet elements in order to clean the receptacle.

As mentioned above, these two outlet elements can be arranged at an angle of 180° with respect to each other in the circumferential direction of the receptacle. These two outlet elements advantageously generate a vortex, the output jets of these vortices being offset by 180° with respect to one another.

In a further advantageous embodiment, the device has at least one annular channel for supplying at least one outlet element with liquid. In particular, the cleaning agent is a dishwashing liquid. In a further advantageous embodiment, the two outlet elements are designed in the same way.

In a further advantageous embodiment, the receptacle has a support ring to which it is attached. This support ring can have fastening elements in order to achieve better assembly of the support ring. For example, two or more fastening ears can be provided on an outer circumference of this support ring, which enable fastening. Three such fasteners are advantageously provided, which are evenly distributed in particular in the circumferential direction of the flange.

In a further advantageous embodiment, the device has a holding device which enables the user to attach the device to another device, such as a sprayer. This holding device can also be combined with the above-mentioned embodiments. However, the applicant also reserves the right to claim protection for a device for filling tanks from a canister with a first adapter device, which is suitable for at least temporary attachment to the canister and which has a feed device via which a flowable medium can be conveyed from the canister into the tank. The device has a detergent connection in order to supply a cleaning liquid to at least one component of the device.

Here the device preferably has a holding device in order to attach the device to another element, such as in particular but not exclusively a spray device. The device here preferably has a receptacle, and the holding device thus also serves to attach this receptacle to another device. In a preferred embodiment, this holding device is arranged in an area in which the receptacle is also located. For example, the holding device can be designed in such a way that it encompasses the receptacle from above and below. This holding device can advantageously also form a receiving space which can accommodate at least one component of the receiving container in its circumferential direction. It is possible for the holding device to have an annular section through which at least one component of the receptacle or another component of the device protrudes.

In a further advantageous embodiment, the holding device has a fastening section which enables this holding device to be fastened to another device in as variable a manner as possible. For example, this fastening section can have a large number of elongated holes in order to achieve the greatest possible versatility. These many mounting options also make it easy to align the system.

In a further advantageous embodiment, the holding device is arranged on the device in such a way that the above-mentioned valves are located above the holding device and are therefore relatively well protected from mechanical influences.

In a further advantageous embodiment, the holding device also has a fastening element in order to be fastened to a discharge line which opens out of the receptacle.

A sectional view of the device according to the invention.

The Figure 1 shows a device 100 for contamination-free filling of a tank 1 from a canister 10 before the canister is coupled to the tank. The device has a tank adapter 6 with a tank fastening flange 36 for fastening to the tank 1 and a first coupling part 62 as well as a canister adapter 2 with a canister fastening flange 23 for fastening to the canister 10 and a second coupling part 4. The canister fastening flange 23 is designed here as a union nut, which interacts with an external thread of an opening in the canister 10. To attach the tank adapter 6 to the tank 1, two mutually rotatable wedge disks are preferably provided.

Figure 2 shows a side view of a device according to the invention without a tank. In particular, a detergent connection 21 can also be seen. This has an external thread 26, for example to connect a detergent hose. The reference numeral 50 denotes in its entirety a ventilation device for ventilating the receptacle 8 in particular. The reference numeral 82 denotes a fastening flange with which the receptacle 8 can be screwed to the device by means of fastening screws 84. The reference number 32 denotes a handle element with which the connection between the coupling parts 4 and 6 can be established or interrupted. The reference number 20 identifies the cleaning device in its entirety

Figure 3 shows a further representation of the device 1 according to the invention. It can be seen that the receptacle 8 has a scale 86 here. This can be used to determine the liquid in the receptacle 8.

The reference number 88 denotes a thread with which, for example, a further valve element can be connected below the receptacle. By means of this valve element, the quantity of liquid in the receptacle 8 can be determined.

The Figures 4a and 4b show two perspective views of a device according to the invention. It can be seen that the receptacle 8 here has a funnel-shaped or cone-shaped lower section 8a.

Figure 5 shows a sectional view of the device according to the invention. It can be seen here that the canister fastening flange 23 itself is attached to a pipe 25 and engages behind it. In addition, a circumferential sealant such as an O-ring can be provided, which creates a fluid seal. The reference numbers 64 and 66 refer to a valve device, which is used in particular for the flushing process. The valve or the valve ball is pushed upwards by a flow and flushing liquid from bottom to top, thereby opening the flushing valve. For this purpose, for example, a pressurized water line can be connected to the detergent connection 21 (cf. Fig. 4b ), which is used to flush the device.

The second coupling part 4 here has an octagonal external cross section, which is designed to be complementary to the first coupling part 41. When the two adapters are plugged together, the second coupling part 4 is inserted into the first coupling part 41. The actuating element 32, designed here as a safety bracket, is used to fix and lock the second coupling part in the first coupling part 41 by pulling it in the direction of the arrow P to the right. The actuating element 32 is approximately U-shaped, with the two legs preferred in the front leg areas are designed to be cranked inwards relative to the remaining leg areas.

To insert the canister adapter into the tank adapter, the actuating element is located with its leg areas in the area of the first coupling part 41, so that the canister adapter can be inserted. By pulling the actuating element 32 in the direction of arrow P, the leg regions of the actuating element are displaced into the area of the first coupling part and there come into engagement with grooves formed with a canister adapter. To release the two adapters, the actuating element is pushed into the tank adapter in the direction of arrow P1 so that the leg areas release the canister adapter again. The reference number 403 denotes a sealing element arranged above the leg regions mentioned, which enables the two coupling parts to be sealed in a coupled state.

For the purpose of cleaning, a first shut-off element 312 designed as a ball valve and the above-mentioned second shut-off element in the form of the ball valve 64 and 66 are formed in the flow path of the cleaning liquid in the area of the connecting channel 311. The first shut-off element is opened via an actuating pin 313 connected to the sliding sleeve 306 when the sliding sleeve 306 is moved into position. Due to the closed position of the first shut-off element 312 according to Figure 5 Leakage of cleaning liquid is reliably prevented even when the cleaning liquid is under pressure, since the pressure of the cleaning liquid presses the shut-off element 312 into its closed position. In addition, the shut-off element is pressed into the closed position with a spring element 314. So that the flushing line is in the closed position when the shut-off element is in the closed position Figure 5 remains unpressurized is a small hole 316 provided, can flow into the tank via any cleaning liquid 6 that may be present.

The reference numbers 22 and 24 identify two cleaning elements in the form of cleaning nozzles, which protrude into the receptacle 8 and which serve to clean the receptacle 8. The cleaning liquid emerging from these cleaning elements 22 and 24 runs spirally down the inner wall of the receptacle, as shown by the solid line L.

Figure 5a shows another representation of the in Figure 5 The device shown here also shows the valve device provided below the receptacle 8. Using the valve device, the container can first be filled with a liquid to be measured. After opening the valve device, the liquid measured for the channel and along the arrow P3 will enter the tank (not shown).

Figure 6a shows a detailed representation of the in Figure 5 device shown, the flow course of a detergent being indicated by the two arrows P4. In particular, an annular channel section 94 can be seen, which distributes the rinsing liquid to the two cleaning elements 22 and 24.

Figure 6b shows a view from below of the in Figure 6 device shown. Here, in particular, the alignment of the two cleaning elements 22 and 24 can be seen, which is such that the detergent emerges along the arrows P5 in a direction that is slightly oblique to the tangential direction of the receptacle 8.

Figure 7a shows the complete detergent flow when liquid is supplied via the detergent connection 26 and the channel 28.

The liquid exits upwards along the arrow P6 and the valve 312; on the other hand, it is distributed to the two cleaning nozzles via an annular channel (along the dotted line). Figure 7b shows the flow of detergent emerging from the cleaning elements 22 and 24 in this view from below. The reference numeral 29 indicates the branch channel that branches off from the channel 28. The detergent connection 26 thus initially opens into the channel 28 and the branch channel 29 branches off from this.

Figures 8a and 8b illustrate ventilation of the receiving container (not shown). The reference number 50 refers to the ventilation device. This has a large number of openings 56 through which air can be sucked in. The reference numeral 52 denotes a valve body which is biased upwards by a spring 54, ie into a closed position of the valve. This means that, on the one hand, air cannot escape through the openings 56 because this is prevented by the valve body 52. On the other hand, the valve is only opened when the receiving container (not shown) reaches a certain negative pressure. The air flow - as shown by the solid line P7 - ultimately passes through the valve into the receiving container (not shown). For this purpose, the device can have a horizontal channel through which air can flow.

Figure 8b shows another representation of the air flow direction. It can be seen that several flows can occur here, so that the air flow can also reach a circumferential channel 94 (upper line) and from there can reach the receiving container (not shown) at several points. This procedure allows the receptacle to be ventilated comparatively quickly.

Figure 9a,b show a further representation of the device, with the flow path of the air for ventilation of the receptacle being shown here in particular. It can be seen that this flow path runs through a channel which is located in the circumferential flange on which the cleaning elements are also arranged. It would also be possible for the same channel to be used for ventilation that is also used for ventilation of the cleaning elements 22 and 24.

Figure 10 shows a top view from below of the device according to the invention. Here too, the flow path of the ventilation air guided in the annular channel is shown again. The ventilation device 50 can also be seen in this illustration.

Figure 11 shows a plan view from above of the device according to the invention. Here too, both the detergent connection and the ventilation device 50 can be seen. It can be seen that the ventilation device 50 is offset by 90° with respect to the detergent channel. The handle element 32 is arranged oppositely with respect to an angle bisector between the ventilation device 50 and the detergent channel. In this way it can be achieved that the operation of the handle element is impaired as little as possible by the detergent channel and the ventilation device and that these cannot be accidentally damaged. The reference number 122 denotes a carrier and the reference number 124 a peripheral wall, which at the same time also forms the flow channel for the liquid to be filled into the canister.

Figure 12 shows a further representation of the device 1 according to the invention. In addition to the configurations of the previous figures, a display device 70 can be seen here, which serves during filling to ensure that the device is filled in a correctly positioned state and in particular in a vertical state of the receptacle becomes. In this case, the measuring device 86 or the scale will form realistic display values. The reference number 72 refers to an air bubble which is arranged within a cavity filled with liquid. In this way, the display device 70 is a so-called dragonfly.

The reference numeral 138 denotes a flange on which the tank adapter is ultimately arranged and the reference numeral 136 denotes a second flange, which is also used in particular for mounting the receptacle 8. These two flanges 136 and 138 can be screwed together.

The reference number 126 denotes a projection on which two actuating elements 150 and 50 are arranged here. The actuating element 150 forms a so-called overflow valve, which serves to allow liquid to be filled if the receptacle 8 is overfilled. The more detailed functionality is described below. The reference number 50 denotes a suction valve or a ventilation valve, which ensures the proper ventilation or venting of the receptacle 8.

Figure 13 shows a further representation of the device according to the invention. You can also see a fastening ring below the receptacle, with which the outlet 90 or the valve device can be arranged. Reference numeral 122 denotes a valve lever with which an exhaust valve can be opened or closed. This valve can be, for example, a ball valve.

The reference numerals 134 identify fastening ears, which can be used in particular to fasten the lower flange 134.

Figure 14 shows a top view of the device according to the invention. Here again the overflow valve 150 and the ventilation valve 50 are shown. The level 70, which is arranged on the top of the flange 138, can also be seen here again.

Figure 15 shows the bottom view of the flange 138. You can see a circumferential channel 162 here, which serves to supply the outlet elements 22 and 24. In addition, the projection 126 can also be seen again, as well as a wide channel 152, through which a flow connection, for example, between the annular channel 162 and the ventilation device 50 can be made, but via which a liquid exchange with the overflow valve 150 is also possible. However, the overflow valve can also be operated by air pressure, with the air being guided through this channel 152 here too. Reference number 154 denotes support webs which support said channel. Both the overflow valve and the venting device 50 can preferably be actuated using air pressure. The reference number 135 denotes a peripheral edge of the flange 138. It can be seen that this has cavities and support elements and is therefore both light and very stable.

Figure 16 shows a side view of the device according to the invention, in particular in the area of the flanges 136 and 138 and the tank adapter. You can see that the overflow device 150 opens into an outlet line 164. Excess liquid can be drained away via this outlet line.

This is in particular liquid, which can occur if the receptacle 8 is overfilled.

Figure 17 shows a sectional view of the in Figure 16 device shown. It can be seen here that the overflow device 50 has a valve device. This valve device has a valve body 174, which is biased downward like a spring by means of a biasing device 172 and in this way closes the channel 168. If increased air pressure occurs, this valve can be opened and excess liquid can be drained off via channel 168. It can be seen that this channel 164 extends through the two flanges 138 and 136.

The ventilation device 50 has a valve body 182, which is designed here as a hollow ball, which is pressed down by the spring 188 in a normal state of the system and thus holds the valve in an open position. However, it is also possible for this open position to be held under the influence of gravity. Reference numeral 184 denotes a valve seat. In this situation, air can flow in and in this way a canister is prevented from collapsing due to negative pressure. If the receptacle is overfilled, the ball floats on the liquid medium flowing from below and thus closes in relation to the sealing seat 184. In this situation, ventilation can no longer take place and in this way the medium can no longer escape. However, it is also possible to stop the air flow using button 193. In this case, negative pressure, which is necessary for suction, can build up. After this negative pressure in the entire system has been reduced, the sensing device 193 opens automatically for safety reasons due to the spring, i.e. under the action of the spring 188.

Figure 18 shows a further representation of the device according to the invention, in which case the device has a holding device 190, which is used to hold the device, for example on a spraying device. This holding device 190 has a rear wall or a fastening surface 192, by means of which the holding device is attached to a device can be attached. For flexible arrangement, this fastening section 192 has a large number of elongated holes, so that fastening is also possible in particular on differently designed fastening elements.

The reference numeral 198 denotes a further fastening section that can be mounted in particular in the area of an outlet of the device. The reference number 196 denotes a support plate of the holding device, which can be mounted here in particular below the flange 138.

Figure 19 shows a view from below of the lower flange 136. Here, too, the two outlet elements 22 and 24 are provided, from which the cleaning medium can emerge along the arrows P5. As mentioned above, spiral cleaning of the receptacle (not shown) is possible in this way. As mentioned above, the two outlet elements 22 and 24 are supplied from an annular channel and ultimately also from the cleaning connection 21.

Figure 20 shows another side view of the device according to the invention. In this view, the arrow P6 also shows how the cleaning liquid travels from the cleaning connection 21 to the outlet elements 22 and 24. For this purpose, a line connection 112 is provided, which also extends through the two flanges 134 and 138. This line connection 112 is particularly straight or extends in a vertical direction.

Figure 21 shows a further more detailed representation to illustrate the ventilation device 50 and the overflow device 150. It can be seen that the overflow device 150 also has an actuating element 175, which is designed as a button. When this button is pressed, the valve body 174 can be pressed against the line 168 and the valve can be closed in this way. Accordingly, it is also possible to actuate the button 168, which forms part of the ventilation device. Pressing this button opens the ventilation device so that the system can be ventilated.
