    The invention relates to a filter device, in particular for freshwater and seawater tanks, according to the preamble of patent claim 1.
    DE 20 2005 001 395 U1 shows a filter device with a filter chamber enclosing a housing, with a rotatably mounted in the filter chamber filter drum, is guided over a part of its circumference a filter belt from a delivery roller to a pickup roller, wherein the pickup roller is driven, so that the filter belt is wound from the delivery roller to the pickup roller. Such filter devices are used, in particular, in freshwater or seawater basins, for example ponds or aquariums, in order to purify the water. In this case, dirt settles on the filter belt, so that the filter belt must be wound from time to time from the delivery roller to the pickup roller to wrap the soiled filter belt from the filter drum to the pickup roller and unwound filter belt from the pickup roller to the filter drum.
    When inserting a new discharge roller with unused filter belt, the pick-up roller must be removed with the soiled filter belt from the device. Since the soiled filter belt is damp and is added with dirt, the pick-up roller has a high weight, which makes it difficult to remove the pick-up roller.
    The object of the invention is therefore to provide a filter device which is easier for the user to use and in which in particular the insertion or replacement of a pickup roller with dirty filter band is simplified.
    The object is achieved according to the invention by a filter device having the features of patent claim 1.
    Advantageous embodiments and modifications of the invention are specified in the dependent claims.
    The filter device according to the invention, in particular for freshwater and seawater basins, with a housing enclosing a filter chamber, with a filter drum rotatably mounted in the filter drum, around which a part of its circumference a filter belt is guided by a delivery roller to a pickup roller, wherein the pickup roller is driven by a drive, so that the filter belt is wound from the delivery roller to the pickup roller, characterized in that the pickup roller is rotatably supported in the housing, wherein between the pickup roller and the drive, a releasable positive connection is arranged. By providing a releasable positive connection a reliable connection between the pickup roller and the drive during operation is ensured in a simple manner, wherein the positive connection for changing the pickup roller can be solved in a simple manner.
    According to a particularly preferred embodiment of the invention, the releasable positive connection is designed as a dog clutch. This is particularly space-saving and easy to use.
    According to a preferred embodiment of the invention, the connection by means of a arranged on the outside of the housing operating unit in and out of engagement can be brought. Thus, the user does not have to reach into the interior of the filter device, but can solve the connection between the pickup roller and the drive from outside the housing.
    Preferably, the operating unit is designed as a lever, which is particularly easy to use and also is inexpensive to produce.
    According to a preferred embodiment of the invention, the pickup roller can be placed on a storage surface when the connection is out of engagement, which is preferably formed by a pivotable flap, in particular by the inside of a lid of the housing. The user does not have to lift the heavy, wet and dirty pickup roller directly from the anchorage completely from the filter device, but can first deposit the pickup roller on the shelf to be able to remove it from the filter device.
    Preferably, the discharge roller can be laid on a storage surface, which is preferably formed by a pivotable flap, in particular by the inside of a lid of the housing. This also allows a simplified introduction of a new discharge roller with unconsumed filter belt.
    Advantageously, the pickup roller and / or the discharge roller is held in each case two fork elements arranged in the housing. As a result, a particularly simple attachment to the rotatable mounting of the pickup roller and / or the delivery roller is achieved.
    According to a particularly preferred embodiment of the invention, the fork elements between a working position and a change position are pivotable. As a result, the change of the pickup roller and / or the delivery roller is further simplified, since the corresponding rollers can be removed more easily from the fork elements, for example, with tilted fork elements.
    A preferred embodiment of the invention provides that the change between working position and change position is done by opening or closing a trained as a pivotable flap storage area. This further simplifies the handling of the filter device, since, for example, when the flap is opened, the fork elements are automatically pivoted into the change position and the fork elements are returned to the working position when the flap is closed, without the user having to take additional measures.
    The invention will be explained in detail with reference to the following figures.

    1 to 9 show different views of a filter device 10, which has a housing 20 with a bottom 21, a cover 22, a front 23, a back 24 and two opposite side walls 25, 26. The housing 20 encloses a filter chamber 15, in which a filter drum 30 is arranged rotatably mounted about a rotational axis 32. The axis of rotation 32 extends in particular between the two side walls 25, 26 substantially horizontally. The wall of the filter drum 30 is permeable to water and may for example consist of a wire mesh, a perforated plate, a sieve or the like. The housing 20 has at least one inflow pipe 27, which can be arranged for example in the side wall 25 and is located in particular in the lower region of the filter chamber 15. In this case, the inflow pipe 27 is arranged outside the filter drum 30, so that by the inflow pipe 27 incoming, to be cleaned water first passes into the outer area around the filter drum 30 of the filter chamber 15. The water can penetrate through the wall of the filter drum 30 into the interior of the filter drum 30. For example, the interior of the filter drum 30 may be filled with a bioactive filter material to purify and bio-treat the water. The purified water can leave the interior of the filter drum 30 by at least one drain pipe 28, which is also arranged, for example, in the side wall 25 within the filter drum 30. The filter device 10 is used in particular to clean freshwater or seawater basins such as aquariums or ponds.
    In order to filter coarse dirt particles from the water, a filter belt 40 is wound over part of the circumference of the filter drum 30, which is in particular designed as a paper web. For this purpose, a discharge roller 50 and a pickup roller 60 are arranged above the filter drum 30 in the filter chamber 15 of the filter device 10. The delivery roller 50 is rotatably mounted about an axis of rotation 52 mounted in the housing 20, while the pickup roller 60 is rotatably mounted about an axis of rotation 62 in the housing 20. In particular, the axes of rotation 52, 62 extend parallel to each other and parallel to the axis of rotation 32 of the filter drum 30. Unused filter belt 40 is provided on the delivery roller 50 while spent, heavily soiled filter belt 40 is wound on the take-up roller 60. In order that the filter belt 40 wraps around a substantial part of the circumference of the filter drum 30 on the way from the delivery roller 50 to the pickup roller 60, deflection rollers 34, 35 are provided (compare in particular FIG. 8). With the help of the filter belt 40 thus coarse contaminants of the water are filtered out before the water to be purified enters the interior of the filter drum 30. The degree of contamination of the filter belt 40 thus increases when cleaning the water until a degree of contamination is reached at which no or almost no water can flow through the filter belt 40 more. The water level in the filter chamber 15 increases in this case. If the rise is too great, unpurified water can flow back into the water basin via an overflow 29, which is arranged in particular in the upper region of the side wall 25, without passing through the filter drum 30.
    Thus, a further cleaning of the water can take place, the filter drum 30 must be further rotated with the filter belt 40, so that unconsumed filter belt 40 rests against the wall of the filter drum 30 again. For this purpose, a drive 90 is provided, which drives the pickup roller 60. The drive 90 may be formed, for example, as a geared motor. So that the drive 90 is not constantly in operation, a fill level sensor 100 is provided, which detects whether the water level in the filter chamber 15 exceeds a defined level. If this is the case, the level sensor 100 outputs a corresponding signal to the drive 90 so that it rotates the pickup roller 60 until unused filter belt 40 is located on the filter drum 30 and water can flow through the unconsumed filter belt 40 into the filter drum 30, so that the level drops in the filter chamber 15 again. Then the drive 90 can be switched off again.
    If the filter belt 40 is used up on the delivery roller 50, a new delivery roller 50 with unused filter belt 40 must be inserted. It is necessary to thread the leading edge of the unconsumed filter belt 40 on the guide roller 34, the filter drum 30 and the guide roller 35 on the pickup roller 60. In order to simplify this process, at least one clip 80, preferably two clips 80, is arranged on the filter drum 30, by means of which the front edge of the unconsumed filter belt 40 can be clamped to the filter drum 30 after being placed over the deflecting roller 34. Alternatively, the filter belt 40 can also be fastened to the filter drum 30 by means of a clamping rail or a tensioning element. Another alternative mounting option is to attach a Velcro strip on the filter drum 30, on which the formed as a paper web filter belt 40 can be fixed. Another alternative is to connect the leading edge of the new filter band to the trailing edge of the old filter band, for example by splice adhesive tape, and to wind the filter band 40 around the filter drum 30 by means of the drive of the take-up roll 60. Subsequently, it is necessary to rotate the filter drum 30, in particular by almost one revolution, until the front edge of the filter belt 40 has approximately reached the deflection roller 35 and the filter belt 40 again almost encloses the filter drum 30. Finally, the leading edge of the filter belt 40 may be secured to the pickup roller 60.
    In order to simplify the rotation of the filter drum 30, an actuator 70 is provided, which may be present as a hand crank, but alternatively also as a handwheel, may be formed. The hand crank has a guided by the side wall 25 transmission element 22, with which the force is transmitted from the actuator 70 to the filter drum 30. In this case, the actuating device 70 is arranged outside the housing 20, so that no intervention of the user in the filter chamber 15 is required to rotate the filter drum 30. It is possible to form the transmission element 72 as an extension of the axis of rotation 32 of the filter drum 30. In the present case, the transmission element 72 in the interior of the housing 20 has a toothed ring 73, which is in engagement with a toothing 74 which is arranged on the lateral outer circumference of the filter drum 30. In this way, a transmission is formed between the actuator 70 and the filter drum 30, which simplifies the rotation of the filter drum 30. The transmission may for example have a reduction ratio of 1:10 or 1:20. Alternatively, a frictional force transmission between the transmission element 72 and the filter drum 30 can take place.
    The pickup roller 60 with dirty filter belt 40 must be removed from the housing 20 and a new pickup roller 60 are used, on which the further filter belt 40 is wound. For this purpose, the connection between the drive 90 and a shaft 64 of the pickup roller 60 must be solved. In the present case, a positive releasable connection 110 is provided for this purpose, which is designed in particular as a dog clutch 116. An end face of the shaft 64 of the pickup roller 60 has for this purpose a contour which engages positively in the opposite end face of the drive shaft of the drive 90, in particular of the geared motor. For this purpose, for example, the end face of the shaft 64 a plurality of claws 66, while on the end face of the drive shaft a plurality of corresponding jaws 126 are arranged. However, the drive shaft and the shaft 64 of the pickup roller 60 may also have an interlocking frontal toothing or the like. Such a positive connection 110 is space-saving and can be solved in a simple manner and brought back into engagement. For this purpose, an operating element 120 is arranged on the outside of the housing 20, which is designed in particular as a lever, and by means of which an axial displacement of the drive shaft of the drive 90 can be brought about to bring the positive connection 110, in particular the dog clutch out of engagement.
    After releasing the connection 110 between the drive shaft and the shaft 64 of the pickup roller 60, the pickup roller 60 can be removed from the housing 20. Since the pickup roller 60 carries wet and therefore heavy filter belt 40, the removal of the pickup roller 60 is facilitated by a storage surface 130. 10 to 12 show a further embodiment of a filter device 10, which has a fold-out flap 140, which serves as a storage surface 130 for the pickup roller 60. Otherwise, the further embodiment corresponds to the first embodiment shown in FIGS. 1 to 9. The flap 140 may simultaneously form the lid 22 of the housing 20 in an alternative embodiment. The user can thus lift the pickup roller 60 out of its attachment in a first step and can first deposit it on the placement surface 130, in order to subsequently completely remove it from the housing 20. A similar storage surface, in particular in the form of a swing-out flap, which in particular forms the cover 22 or part of the lid 22, can also be provided for the delivery roller 50.
    The pickup roller 60 and the discharge roller 50 are rotatably supported inside the housing 20. For this purpose, in particular fork elements 150 are provided, which are described in more detail with reference to the further embodiment of a filter device 10 shown in FIGS. 13 and 14. Otherwise, the further embodiment corresponds to the first embodiment shown in FIGS. 1 to 9. The shaft 64 of the pickup roller 60 is held in two fork members 150. In this case, the fork elements 150 are arranged in a working position such that an opening 152 of the fork elements 150 faces upward, so that the shaft 64 of the pickup roller 60 is securely held in the fork elements 150. The fork elements 150 are pivotable from the working position into a change position, which is shown in particular in FIG. 14. In the change position, the opening 152 is approximately laterally, so that the shaft 64 of the pickup roller 60 can be easily pushed out of the fork elements 150. In this case, in a preferred embodiment, a support surface 154 for the shaft 64 is provided on the fork elements 150. The change between the working position and the change position is carried out according to the illustrated embodiment by pivoting the flap 140, to which the fork elements 150 are attached. When the flap 140 is closed, the fork elements 150 are in the working position, while the fork elements 150 are in the change position with the flap 140 open. The dispensing roller 50 is preferably equipped in the same manner with fork members 150 and a hinged flap 140.
