'Conveyor-belt filter device'
The present invention relates to a conveyor-belt filter device for mechanically rinsing a fluid which is polluted with solids and flows in a channel or the like using an endless filter belt, which comprises interconnected filter elements which can each be pivoted about a horizontal axis relative to one another and which has a filter bottom, through which media can flow and which can be conveyed over an upper and a lower deflection area of a framework by means of a driving means connected to the filter elements and arranged along a conveyor track formed on the framework.
Conveyor-belt filter devices of the make mentioned above are mostly used for cleaning sewage, in particular coarse impurities, contained in the sewage stream, being detained by the filter bottoms of the filter elements and being removed from the streaming sewage by means of filter screens arranged on the filter elements and being collected by means of a discharge device arranged in an upper deflection area of the conveyor-belt filter device to the side of the sewage channel and subsequently being disposed of.
Conveyor-belt filter devices of the make mentioned above, however, can also be used for filtering water in lakes, rivers or the ocean, the water streaming towards the filter device being subsequently supplied to a water treatment plant, which can serve for preparing drinking water, for example. By using such a conveyor-belt filter device, a specific problem arises, namely of fish, which get caught in the influx area of the conveyor-belt filter device, in particular due to the high current, not being able swim back into open waters or being hurt by coming into contact with the conveyor-belt filter device. Therefore, in order to protect the stock of fish in a stretch of water, whose outlet is provided with a conveyorbelt filter device, it has proven necessary to remove fish, which have become caught in the influx area of the conveyor-belt filter device, from the danger zone as soon as possible so that the fish can be returned to open waters.
It is therefore the task of the present invention to propose a conveyorbelt filter device which comprises suitable installations which enable removing fish, which have become caught in the influx area of the conveyor-belt filter device, from the influx area.
In order to attain this object, the conveyor-belt filter device according to the invention comprises the features of claim 1.
According to the invention, the filter belt comprises at least one transport pouch arranged between adjacent filter elements, having a pouch opening formed on the front side which is positioned in the conveying direction, said transport pouch projecting above a filter plane defined by the filter bottoms of the filter elements with a front edge of the front side, a collecting device being provided in the transfer area formed adjacent to the upper deflection area in the conveying direction, said collecting device being arranged at a distance to the filter belt in so as to convey the transport pouch through a through opening formed between the collecting device and the filter plane, said through opening being provided with a controllable covering device for covering the through opening and for temporarily opening the through opening while the transport pouch passes through the through opening.
The conveyor-belt filter device realized according to the invention thus enables removing fish from the influx area of the conveyor-belt filter device without affecting the operation of the conveyor-belt filter device.
For this purpose, a through opening is provided between the collecting device required for removing the fish and the filter belt while the filter belt revolves, said through opening preventing that the at least one transport pouch, which projects above the plane of the filter bottoms of the filter elements, collides with the collecting device while the transport pouch moves past said collecting device. At the same time, it is prevented that a gap is formed between the collecting device and the filter plane while transferring the fish from the transport pouch to the collecting device, since said gap could endanger the fish while they are being transferred from the transport pouch to the collecting device.
For this purpose, the gap forming the through opening is solely temporarily covered by the covering device during the transfer so that it is in particular also prevented that a sewage-water volume, which was previously collected from the influx area of the conveyor-belt filter device in conjunction with the fish, is drained from the transport pouch unchecked. Indeed, the sewage-water volume is available as a conveying means while transferring the fish into the collecting device, said conveying means accelerating transferring the fish into the collecting device on the one hand and enabling a particularly careful transfer of the fish from the transport pouch into the collecting device by forming a fluid buffer on the other hand.
It is particularly advantageous if the covering device comprises a covering element and a control device for actuating the covering element so that the covering element can be adjusted in a particular manner for transferring fish from the transport pouch into the collecting device independently of how the control device is realized.
Preferably, on a connecting side, the covering element is pivotably connected to an opening edge of the collecting device in order to execute a relative movement with respect to the collecting device and can be pressurized on the contact side with the control device formed on the filter belt so that the covering element is more or less formed like a kind of pivotable flap and can be realized with relatively little mass due to the control device realized independently of the covering element at the filter belt and can thus be easily moved.
Preferably, at least the transport pouch is provided with a guiding element, which defines a control curve, in order to realize the control device and the contact side of the covering element is provided with a contacting device for being contacted against the guiding element. In this way, a coupling as direct as possible between the temporary presence of the transport pouch in the area of the covering element is enabled while passing the transport pouch through at the collecting device.
It has proven particularly advantageous if the control device comprises a plurality of guiding elements which are arranged on the transport pouch and on at least one filter element, which precedes the transport pouch in the conveying direction, so that it is not only achieved that the covering element opens the through opening while the transport pouch is passed past the collecting device but also that, moreover, a minimized distance is formed between the covering element and the filter bottoms during the transfer of fish from the transport pouch into the collecting device, during which transfer the transport pouch is in the upper deflection area, namely in an area of the revolution path arranged before the collecting device as viewed from the conveying direction, in order to mostly preclude any loss of fluid while emptying the transport pouch into the collecting device.
If, in order to form the contacting device of the covering element, a preloading device is arranged between the collecting device and the covering element in such a manner that the covering element is brought into contact against the guiding element with a contact side, a direct kinematic coupling can be realized between the covering element and the control device using little constructive expenditure.
Preferably, a sliding or rolling device is provided at the covering element in order to form the contacting device.
It is particularly advantageous if the transport pouch comprises a concave pouch bottom, which is arranged opposite the front edge and which extends between adjacent hinge axes of the filter belt, in such a manner that the pouch bottom forms a reception device for fluids in the deflec5 tion point of the upper deflection area during conveyance so as to ensure that a sewage-water volume remains in the transport pouch for as long as possible while transferring the content from the transport pouch to the collecting device so that fish arranged on the pouch bottom remain in a fluid environment in the transport pouch for as long as necessary.
Preferably, a flooding device is arranged above the upper deflection area and at a lateral offset to the deflection area in the transfer area in order to complement supplying fluid into a sewage-water volume which was drained from the transport pouch into the collecting device, said transport pouch being arranged in the deflection area. Thus, the sewagewater volume previously taken from the influx area and transferred into the collecting device during the transfer with the fish is complemented in volume in order to ensure that the fish are supplied with enough fluid volume during the transfer, namely during the time during which the fish are no longer in the transport pouch but are not yet in the collecting device.
It is particularly preferable if the collecting device is provided with a rinsing device for dispensing the content of the collecting device into a drain connected to the collecting device so that the fish do not have to be returned into the stretch of water arranged before the conveyor-belt filter device and be transported into the water by manually removing the fish from the collecting device but rather by automatically returning the fish via a rinsing process of the collecting device and by subsequently conveying the fish through the drain into the stretch of water, said drain being connected to the collecting device.
In the following, a preferred embodiment of the invention is further described by way of the drawing.

Fig. 1
Fig. 1 shows a conveyor-belt filter device 11 arranged in a removal channel 10 which is connected to a stretch of water, said conveyor-belt filter device 11 comprising a framework 12 having a filter belt 14 arranged thereto, said filter belt 14 comprising a plurality of filter elements 13, 63, 64. The filter belt 14 comprises two driving means, which are each connected to longitudinal ends 33, 34 of the filter elements 13, 63, 64 and which are preferably realized as chains and which are not further shown here, said driving means revolving on a conveyor track formed in the framework 12 in conjunction with the filter elements 13,
63, 64 arranged thereon and thus being deflected to an upper deflection area 15 and a lower deflection area 16. A driving device 18 is arranged on the framework 12 in the upper deflection area 16 in order to drive the filter belt 14.
As seen in Fig. 1, the conveyor-belt filter device 11 is arranged in the removal channel 10 in such a manner that the filter elements 13, 63, 64 of the filter belt 14 extend in the flow direction and that the framework 12 is supported on a channel ground 20 in an arrangement positioned, for example, on a channel middle axis 19. For completion, two supporting crosspieces 21 are provided above a lower part of the framework 12, said lower part protruding into the removal channel 10, said supporting crosspieces 21 supporting the conveyor-belt filter device 11 on channel edges 22. In total, this results in an arrangement of the conveyor-belt filter device, as can be seen in Fig. 1, in which arrangement the conveyor-belt filter device is arranged above a channel level 23 with an upper part 3 1 of the framework 12, the lower part of the framework 12 extending from the channel level 23 to the channel bottom.
As a synopsis of Figs. 1 and 2 shows, the framework 12, on an influx side 24 of the conveyor-belt filter device 11, is provided with a partition plate 28 arranged on the framework 12 and, on a reflux side 25, there is a partition plate 29 arranged between the framework 12 and an adjacent channel 26, 27 in each instance so that a flow through the conveyor-belt filter device 11 is realized such that the filter elements 13, 63, 64 of the filter belt 14 are flowed through towards the inside from the outside on the influx side 24 and an interior 30 of the conveyor-belt filter device 11 limited by the filter elements 13, 63, 64 is centrally refluxed on the reflux side 25 of the conveyor-belt filter device 11.
Fig. 3 shows the upper part 3 1 of the conveyor-belt filter device 11 in a cross section according to cut III-III shown in Fig. 1, said upper part 31 being arranged above the channel level 23 and having the filter belt 14 deflected in the upper deflection area 16. Besides a plurality of filter elements 13, 63 and 64, the filter belt 14 comprises transport pouches 32, which are individually arranged between two respective filter elements 13 and 63 and which are realized in such a manner that they can be integrated interchangeable with a filter element 13 at any arbitrary position of the filter belt 14. As seen in Fig. 3, the filter elements 13,
63, 64 are connected to each other and to the transport pouch 32 via hinge axes, which are formed by bolts 61 of the drive chain, not further shown here, in the present case. The filter belt 14 formed by the filter elements 13, 63, 64 and the transport pouches 32, which have been hinged together, is driven in the upper deflection area 16 by the driving device 18 shown in Fig. 1.
As a synopsis of Figs. 1 and 3 shows, the filter elements 13, 63, 64 and the transport pouch 32, which is shown in an isometric view in Fig. 7, are provided with guiding elements 35, 36 and 38 at their longitudinal edges 33, 34, said guiding elements 35, 36 and 38 being guided past a trough-shaped collecting device 39 arranged below the upper deflection area 16 and on the upper part 3 1 of the framework 12 at a lateral offset to the deflection area 16 when the filter belt 14 rotates, a gap being formed between an opening edge 51 of the collecting device 39 and the filter belt 14, said gap enabling a through opening 41 when the transport pouches 32 arranged individually in the filter belt 14, as shown in Fig. 6, are guided past the collecting device 39 in a counterclockwise direction.
As in particular Fig. 3 shows, with exception of the transport pouches 32 and the two filter elements 63, 64, which each directly precede a transport pouch 32 when the filter belt 14 revolves, all other filter elements 13 are provided with guiding elements 35 comprising a guiding contour 45. The guiding elements 38 arranged on the transport pouches 32 comprise a guiding contour 44, the filter element 63 directly preceding the transport pouch 32 is formed without a guiding element, and the filter element 64 arranged between the filter element 63 and the filter element 13 comprises the guiding element 36 provided with a guiding contour 42. A control curve is defined by the arrangement of the different guiding contours 45, 42 and 44 of the guiding elements 35, 36 and 38 in a row, said control curve being moved past the collecting device 39 via the through opening 41 when the filter belt 14 revolves.
As Fig. 3 shows, the collecting device 39 provided with a covering device 40, which comprises a covering element 46 and a control device 52, said covering element 46 being pivotably connected to a connection side 47 on the opening edge 51 of the collecting device 39. Contact rolls 49 are provided on a contact side 48 of the covering element 46 arranged opposite the connection side 47, said contact rolls 49 resting against the guiding contours 45, 42 and 44 of the guiding elements 35, 36 and 38, which were moved past. In order to generate a contact force, which ensures that the contact side 48 of the covering element 46 constantly rests against the guiding elements 35 to 38, a pre-load device can be provided on the covering element 46, said pre-load device being realized as a leg spring, for example, and supporting itself on the opening edge 51 of the collecting device 39. When the guiding elements 35, 36 and 38 are moved past the collecting device 39, the guiding elements 35, 36 and 38 form a control device 52, which triggers a pivoting movement of the covering element 46 resting against the guiding elements 35 to 38 by means of the contact force so that the distance between the contact side 48 of the covering element 46 and a filter plane 54 defined by filter bottoms 53 and thus the width of the through opening 41 is changed while the filter belt 14 rotates.
Fig. 3 shows the covering element 46 in a configuration, in which the distance between the contact side 48 of the covering element 46 and the filter plane 54 is at its maximum. This maximal distance amax is attained as long as filter elements 13, which are provided with the guiding elements 35 comprising the constant guiding contour 45, are moved past the collecting device 39.
In Fig. 4, the contact rolls 49 of the covering element 46 are shown directly before the constant guiding contour 45 of a guiding element 35 transitions into the guiding contour 42 of the guiding element 36 arranged on the filter element 64, said guiding contour 42 dropping towards the filter plane 54. During the progression of the guiding contour
42, the covering element 46 moves to a configuration shown in Fig. 5, in which configuration the contact rolls 49 of the covering element 46 rest against an abutment formed on the framework 12 so that a minimal distance amin is attained between the contact side 48 of the covering element 46 and the filter plane 54.
Starting from the configuration shown in Fig. 5, in which configuration the filter element 63 passes the through opening 41, the covering element 46, as shown in Fig. 6, pivots outwards when the contact rolls 49 abut against the rising guiding contour 44 of the guiding element 38 formed on the transport pouch 32 in order to enlarge the distance so that the maximal distance amax, which is shown in Fig. 3, is eventually attained again.
As can be seen in Fig. 7, the transport pouches 32 comprise a concave pouch bottom 57 arranged opposite a front edge 55 of a front side 56, a pouch opening 58 being defined by the distance of the front edge 55 from the pouch bottom 57. During an upward movement of a transport pouch 32 in the channel stream below the water level 23, fish positioned in front of the filter plane 54 find their way into the transport pouch 32 and are removed from the removal channel 10 in conjunction with a channel-water volume and are conveyed along the conveyor track of the filter belt 14 to the upper deflection area 16.
When the transport pouch 32, as shown in Fig. 4, reaches the upper deflection area, the covering element 46 is first moved into the configuration shown in Fig. 5 via the guiding element 36 arranged on the filter element 64, in which configuration the minimal distance amin is attained and the content of the transport pouch 32, possibly containing a fish, and the channel-water volume removed from the removal channel 10 is transferred into the collecting device 39. In this way, the channel-water volume transferred from the transport pouch 32 into the collecting device 39 is complemented by a flooding device 62 arranged at a lateral offset to the deflection area 16, said flooding device 62 comprising a watercarrying conduit 59 having an overflow edge 60 (Fig. 3).
During the transfer, the filter element 63 passes the through opening 41.
After the content of the transport pouch 32 has been transferred into the 5 collecting device 39, the covering element 46 is pivoted away from the filter plane 54 by contacting the guiding element 38 of the transport pouch 32 until the maximal distance amax has been attained so that the through opening 41 is released for the passage of the transport pouch 32, which projects above the filter elements 13, 63 and 64 with its front edge
55.
