Detailed Description

According to fig. 1, 2, 3 and 4, the invention relates to a water cleaning device (1) for running water (3).

In general, the water cleaning device (1) may comprise two, three, four, five, six or more water cleaning units (2, 6) which are arranged one after the other in the flow direction (4) and are preferably spaced apart from one another by a distance (20).

According to fig. 1 to 4, in top view, an end (8) of one water cleaning unit (2) may be indirectly or directly connected to one bank (5), while an end (9) of the opposite other water cleaning unit (6) is indirectly or directly connected to the other opposite bank (7) in top view.

Fig. 1, 2, 3 and 4 show that the free ends (10, 11) of the water cleaning units (2, 6) projecting in the direction of the running water (3) can overlap one another in a top view in an overlap region (23) relative to the flow direction (4).

In general, the water cleaning device (1) comprises two or more water cleaning units (2, 6) spaced apart from each other in the flow direction (4), and overall, in top view, each water cleaning unit (2, 6) may extend over a maximum width (15) of the running water (3).

Fig. 1, 2, 3 and 4 show an overlap region (23) between the free ends (10, 11) of the cooperating water cleaning units (2, 6), the individual water cleaning units (2, 6) being offset in the flow direction (4) by a distance (20) with respect to each other and extending from opposite banks (5, 7), wherein the width of the overlap region may be in the range of, for example, 0.1m to 1000.0m, preferably in the range of 0.2m to 900.0m, in particular in the range of 0.3m to 800.0 m.

The width (19) of the individual water cleaning units (2, 6), measured in the direction of the width (15) of the running water (3), can generally be the same or different from one another. For example, the width (19) of each water cleaning unit (2, 6), including the optionally provided strip-shaped screen (17), may be in the range of 2.0m to 500.0m, preferably in the range of 2.5m to 400.0m, in particular in the range of 3.0m to 300.0 m.

Fig. 1, 2 and 4 show a spacing (20) between two water cleaning units (2, 6) in the flow direction (4), wherein, in a top view, the spacing may be in the range of, for example, 1.0m to 500.0m, preferably in the range of 1.5m to 400.0m, in particular in the range of 2.0m to 300.0 m.

In a first embodiment according to fig. 1 and 2, the angle α between an imaginary longitudinal axis (22) passing through the respective water cleaning unit (2 and/or 6) on the one hand and the flow direction (4) of the running water (3) on the other hand is, for example, in the range from 20 ° to 90.0 °, preferably in the range from 30 ° to 90.0 °, in particular in the range from 40 ° to 90.0 °. In this case, said included angles α of two opposing water cleaning units (2, 6) may be the same or different from each other.

In a second embodiment according to fig. 4, the angle α between an imaginary longitudinal axis (22) running through the upstream water cleaning unit (2) on the one hand and the flow direction (4) of the running water (3) on the other hand is, for example, in the range from 170.0 ° to 89.9 °, preferably in the range from 160.0 ° to 80.0 °, in particular in the range from 150 ° to 70.0 °. In this case, said included angles α of two opposing water cleaning units (2, 6) may be the same or different from each other.

According to fig. 4, in this second embodiment, the angle between an imaginary longitudinal axis (22) running through the downstream water cleaning unit (6) on the one hand and the flow direction (4) of the running water (3) on the other hand is α, which is, for example, in the range from 20 ° to 90.0 °, preferably in the range from 30 ° to 90.0 °, in particular in the range from 40 ° to 90.0 °.

In the water cleaning device (1) of the invention, the angles α between the longitudinal axes (22) of the opposing water cleaning units (2, 6) on the one hand and the flow direction (4) of the running water (3) on the other hand can be identical to or different from each other, depending on the upstream or downstream position.

Due to the orientation of the row of screening drums (13) with such an inclination of the angle α, the flow of the running water (3) causes or at least promotes self-cleaning removal of floating material which is collected by the row of screening drums (13) or the strip-shaped screen (12) in the direction of the ends (8, 9) of the respective water cleaning unit (2, 6) on the bank side.

According to a second embodiment, which is shown in fig. 4, the longitudinal axis (22) of the upstream water cleaning unit (2) can be inclined in the direction of the center of the running water (3) in a plan view. In this case, the top side of the screening drum (14) of the upstream water cleaning unit (2) is driven in rotation, preferably in the direction of the centre of the running water (3).

In this way, with the aid of the running water (3), the floaters collected on the upstream water cleaning unit (2) are conveyed in the direction of the free end (10) of the upstream water cleaning unit (2) and then released again into the running water (3) at this location.

In this second design alternative, the floaters released into the running water (3) at the free end (10) of the upstream water cleaning unit (2) are collected by the downstream water cleaning unit (6), the downstream end (9) of the downstream water cleaning unit (6) being indirectly connected to the bank (7) supporting the downstream water cleaning unit (6), for example by a strip screen (17).

It can be seen that a particular advantage of the second design described above is that-unlike the first design described with reference to figure 1, in which two clearing devices (17) for floating material are provided on two opposing banks (5, 7) -only one single clearing device (17) for floaters needs to be arranged between the downstream water cleaning unit (6) and the bank (7) supporting it.

If the corresponding infrastructure (composting system, walkway, etc.) is not adequately provided on both banks (5, 7), the normal operation of the water cleaning device (1) according to the invention can be achieved for the first time by providing only one of the two banks (5 and 7) with the conventional infrastructure for operating the water purification device.

In general, the constructional design of the individual water cleaning units (2, 6) can be identical to or different from one another (compare fig. 1, 2, 3 and 4).

For example, the water cleaning units (2, 6) may be implemented in the form of strip screens (12), respectively, with vertical and horizontal screen bars — including an associated screen cleaning system (25) (fig. 2 and 3).

Alternatively, the water cleaning units (2, 6) may be implemented in the form of screening drum rows (13), respectively (see fig. 1 and 4).

Each row (13) of screening drums may typically comprise rows (13) of screening drums (14), the screening drums (14) being rotatable about their vertical axes, wherein, in top view, the individual screening drums (14) may be driven in the same direction or in opposite directions-with reference to the upstream drum surface-i.e. in the direction of the bank (5, 7) supporting the respective water cleaning unit (2, 6) indirectly or directly or in the direction of the strip screen (17) of the downstream water cleaning unit (6).

In the embodiment shown in fig. 4, the screening drums (14) of two opposite rows (13) of screening drums may have the same direction of rotation in top view, wherein these directions of rotation are oriented in the direction of the downstream water cleaning unit (2 or 6) used in cooperation with the screen cleaning device (25).

Thus, in a particularly preferred embodiment shown in fig. 1 and 4, the respective water cleaning unit (2, 6) may be realized in the form of a screening drum row (13) consisting of a plurality of screening drums (14) which can rotate about their vertical axis.

Preferably, wipers (16) in the form of vertical strips can be arranged between the vertically oriented screening drums (14) in each case.

Fig. 1 shows in particular a strip-shaped screen (17) which can be provided in each case between the end (8, 9) of the respective water cleaning unit (2, 6) which points in the direction of the associated bank (5, 7) and the bank (5, 7) which indirectly or directly supports the water cleaning unit (2, 6).

For example, the strip-shaped screen (17) can comprise vertically or horizontally oriented screen strips and associated screen cleaning devices (25) which function at least in the direction of the adjacent bank (5, 7).

According to fig. 4, the water cleaning device (1) of the present invention may comprise only a single strip screen (17) -between the downstream end (9) of the downstream water cleaning device (6) and the bank (7) indirectly supporting the downstream water cleaning device (6).

In general, the width (24) of the optionally provided strip screen or screens (17) can be identical to or different from one another and is, for example, in the range from 0.4m to 50.0m, preferably in the range from 0.5 to 40.0m, in particular in the range from 0.6m to 30.0 m.

The screening drums (14) of each row (13) of screening drums may rotate in the same direction of rotation (see fig. 4) or in different directions of rotation (see fig. 1) around their respective vertical axes, usually at the same rotational speed or at different rotational speeds.

Each screening drum (14) may preferably be rotationally driven around its vertical axis at a speed, for example, in the range of 0.1 revolutions per minute (rpm) to 20.0rpm, preferably in the range of 0.2rpm to 18.0rpm, in particular in the range of 0.3rpm to 16 rpm.

In general, the diameters (21) of the screening drums (14) can be identical or different from one another in top view and are, for example, in the range from 0.2m to 15m, preferably in the range from 0.4m to 11.0m, particularly preferably in the range from 0.5m to 9.0 m.

In a particularly preferred embodiment of the water cleaning device (1) of the invention, the distance between the individual vertical or horizontal screening strips or between the screening elements of the screening drum (14) may be, for example, in the range from 1.0mm to 300.0mm, preferably in the range from 1.5mm to 250.0mm, particularly preferably in the range from 2.0mm to 200.0 mm.

According to fig. 1, 2, 3 and 4, the distance (18) between the free end (10, 11) of the water cleaning unit (2, 6) on the one hand and the corresponding opposite bank (5, 7) on the other hand can be identical or different from one another and is, for example, in the range from 1.0m to 200.0m, preferably in the range from 1.5m to 150.0m, particularly preferably in the range from 2.0m to 100.0 m.

In general, the flow rate of the flowing water (3) to be cleaned may be, for example, in the range of 0.05m/sec to 15.0m/sec, preferably in the range of 0.1m/sec to 11.0m/sec, particularly preferably in the range of 0.2m/sec and 9.0 m/sec.

For example, the width (15) of the running water (3) can be in the range from 1.0m to 1000.0m, preferably in the range from 1.5m to 900.0m, particularly preferably in the range from 2.0m to 800.0 m.

In summary, the present invention provides a water cleaning device (1) for running water (3) which does not block the flow of the running water (3) if the water cleaning device is damaged or blocked.

Due to the inventive option of flowing the running water (3) laterally or obliquely through the overlap region (23), flooding of the bank regions (5, 7) on both sides can be reliably prevented even in the case of a very unlikely complete blockage of the water cleaning device (1) according to the invention.

It can be seen that a particular advantage of the water cleaning device (1) according to the invention is that, due to the selection of an unobstructed passage through the overlapping region (23), a completely unobstructed passage of fish is possible. This is very advantageous in particular in terms of natural protection.

A further advantage of the water cleaning device (1) according to the invention is that, in addition to its very good cleaning effect, it is still possible to pass the ship through the overlapping area (23) of the openings without obstacles and at a very low cost.

Furthermore, the water cleaning device (1) of the invention is also advantageous in that it no longer requires the use of expensive high maintenance gates due to the optional passage through the overlapping area (23) of the openings.

Second embodiment, only one screen cleaning device (25) in the form of a strip screen (17) for removing floating material is arranged between the downstream end (9) of the downstream water cleaning unit (6) on the one hand and the bank (7) which indirectly supports the downstream water cleaning unit (6) on the other hand, wherein the angle α between the longitudinal axis (22) of the upstream water cleaning unit (2) and the direction of flow (4) of the running water (3) is in the range from 170.0 ° to 89.9 °, and the angle α between the longitudinal axis (22) of the downstream water cleaning unit (6) and the direction of flow (4) of the running water (3) is in the range from 20.0 ° to 90.0 °, has the particular advantage that the high-efficiency water cleaning device (1) shown in fig. 4 can now also be used for running water (3) which is equipped only with the infrastructure required for the correct operation of the water cleaning device on a single bank (5 or 7) (for example a composting system, a method for cleaning a method for producing a water, Channels, etc.).
