The invention relates to a pond filter arrangement containing

• (a) a housing having a pond water inlet and a pond water outlet;
• (b) fluidizable filter material disposed in the housing; and
• (c) pond water from the pond water inlet ( 22 ) through the filter material ( 54 ) to the pond water outlet ( 24 ) is conductive.

With such a pond filter arrangement dirt particles are filtered from pond water. The water is passed through the filter material. The dirt particles in the filter material remain hanging.

State of the art

The Beyersdörfer GmbH sells on the website under the name "Ultrabead" www.koiteich.de a pond filter. The pond filter has a fluidizable filter material in the form of floating filter balls, which are referred to as "beads". The pond water is pressed by a pump through the beads and the dirt particles hang between the beads. To clean the balls, the filter material is backwashed with pond water. For this purpose, a complicated 6-way cock is provided. Dirt particles from the pond water can still get caught in the filter material during backwashing.

Disclosure of the invention

It is an object of the invention to provide an arrangement of the type mentioned, which allows a good cleaning, simple and easy to use.

• (d) ein separater, absperrbarer Spülwasser-Einlass und ein absperrbarer Spülwasser-Auslass an dem Gehäuse vorgesehen sind;
• (e) der Spülwasser-Einlass eine Belüftungsöffnung mit einem zum Gehäuseinneren öffnenden Rückflussverhinderer aufweist; und
• (f) der Spülwasser-Einlass im inneren Bereich des Filtermaterials mündet, so dass ein Spülwasser-Luftgemisch unter Mitnahme von Partikeln aus dem Filtermaterial zum Spülwasser-Auslass geleitet wird.

According to the invention the object is achieved in that

• (D) a separate, lockable flushing water inlet and a shut-off flushing water outlet are provided on the housing;
• (e) the rinse water inlet has a vent opening with a backflow preventer opening to the housing interior; and
• (F) the rinse water inlet opens in the inner region of the filter material, so that a rinse water-air mixture is guided with entrainment of particles from the filter material to the rinse water outlet.

Fresh water can be directed into the arrangement via the separate rinse water inlet. The fresh water can be supplied for example via a standardized connection by means of a garden hose or the like. The rinse water outlet can be connected to the sewer or drain. Rinsing water, with which the filter material is rinsed, is so easily derived. During the backwashing process, air passes through the ventilation opening and is added to the rinse water. The water-air mixture is introduced into the filter material. As a result, a particularly good turbulence is achieved. This dirt particles are released from the filter material and washed away.

Unlike filter wool or screens, fluidizable filter material consists of a plurality of particles, such as spheres or other granular material. The filter material can be swirled by a suitable flow and pick up dirt particles during the filtering process and release again when backwashing.

Preferably, the fluidizable filter material comprises a plurality of floating beads, for example of plastic. These are inexpensive, durable and have good filter properties.

In one embodiment of the invention, the pond water inlet opens into an inlet channel whose opening is oriented such that the pond water flows along a selected flow direction, in particular spirally through the filter material. For example, the input channel may be aligned with the opening in the circumferential direction. A cylindrical housing is particularly well suited. As a result, a circulating, spiral flow is achieved. Heavier particles are already pressed before reaching the filter material due to the centrifugal force to the housing and accumulate there. They are then easier to remove.

Preferably, the area between the opening of the inlet channel and the filter material and the area between the filter material and the pond water outlet are each separated from a sieve. The screen preferably has an opening size which does not pass the filter material.

In a preferred embodiment of the invention, the rinse water inlet opens in a branched rinsing water channel, wherein the branches have openings in the region of the filter material. As a result, a particularly good turbulence and cleaning effect is achieved.

The Spülwasserauslass may be provided on the pond water outlet opposite side of the housing. In particular, the pond water inlet next to the pond water Outlet in the upper region and the flushing water outlet be arranged in the bottom region of the housing. Then pond water inlet and pond water outlet are easily accessible. Coarse dirt particles that collect on the floor are easily removed via the flushing water outlet during backwashing.

In one embodiment of the invention, the rinse water inlet is provided laterally in a connection fitting in the upper region of the housing and opens via a downward curvature in a substantially vertically extending Spülwasserkanal and the ventilation opening is provided flush with the flushing water channel in the connection fitting. The flow generated by opening the shut-off of the flushing water inlet and the flushing water outlet then entrains air. With a rinse water-air mixture a particularly good cleaning effect is generated.

Preferably, the flushing water channel has lateral, diametrically opposite branches in two planes. As a result, a good turbulence of the filter material is achieved.

Embodiments of the invention are the subject of the dependent claims. An embodiment is explained below with reference to the accompanying drawings.

Description of the embodiment

1 to 3 show a general with 10 designated pond filter arrangement. The pond filter arrangement 10 includes a housing 12 that with a lid 14 is closed. The lid 14 is for fixing a unique position relative to the housing 12 glued to the housing. The housing 12 sits in a stand 16 ,

In the lid 14 is one with a transparent viewing window 18 closed view and access opening provided. The viewing and access opening allows the filling and emptying of the in the housing 12 located filter material and the observation of its condition.

Centered in the lid 14 is a connection fitting 20 integrated in the lid. The connection fitting 20 has a pond water inlet 22 and a pond water outlet 24 on. The pond water inlet 22 is with a cock 26 shut off. The pond water outlet 24 is with a cock 28 shut off. A pump (not shown) pumps the pond water to be filtered to the pond water inlet 22 , The water flows through the housing 12 in the manner described below to the pond water outlet 24 and is filtered. Then it is returned to the pond.

Between the pond water inlet 22 and the pond water outlet 24 is a rinse water inlet 30 arranged. The rinse water inlet 30 is with a ball valve 32 shut off. The rinse water inlet 30 is a standardized connection, so that according to a standard garden hose can be connected to the flushing water inlet. In particular, fresh water is then used as rinse water. The fitting 20 also has a ventilation opening 34 on.

At the bottom of the case 12 is a flushing water outlet 36 arranged. Also the rinse water outlet 36 is with a cock 38 shut off. The rinse water outlet is connected to a water disposal, such as the sewer.

4 illustrates, by means of a cross-section, the flow conditions while the water is being filtered. Pond water flows through the pond water inlet 22 in the filter assembly. The pond water inlet opens into a tubular inlet channel 40 , The input channel 40 extends over the entire height of the housing 12 to the bottom area 42 , The input channel 40 runs at the end as an L-shaped tube in a horizontal plane over the bottom area 42 , This is in 5 and 6 to recognize. The exit 44 of the tube points in the circumferential direction. Thereby, a circulating flow is generated in the circumferential direction, as by arrows 46 in 5 is shown. Due to the centrifugal force thus generated on the particles larger particles in the bottom area to the inner wall of the housing 12 pressed and so do not burden the filter material.

The flow is approximately spiraling upward, as indicated by arrows 48 in 4 is shown. Just above the floor area 42 is a sieve 50 intended. The sieve 50 is slightly curved downwards and has a large number of slots 52 on. filter material 54 which is above the screen 50 can not swim through the slits 52 pass. Coarse particles also can not pass through the slots 52 pass. The floor 42 of the housing 12 is thus always free of filter material. There, coarse particles collect.

The filter material 54 consists of a large number of floating plastic beads called beads. Such beads and their action are known from the prior art and therefore need not be described in detail here. The pond water flows through the filter material 54 and is filtered. At the top of the case 12 is another, concave sieve 56 intended. The water flows through the sieve 56 to the pond water outlet 24 and is there again for use in the pond. The mesh size of the sieve 56 is also so small that the beads are retained in the housing.

If the filter is dirty, the filter material may 54 backwashed and so cleaned. For this, the pond water inlet 22 and the pond water outlet 24 with the taps 26 and 28 shut off. The pond water flow is thus interrupted. Subsequently, the cock 32 at the rinse water inlet 30 and the rinse water outlet 36 open. A garden hose (not shown) is connected to the flushing water inlet for this purpose 30 connected. This will create a flow through the housing 12 generated in 7 is illustrated.

The rinse water inlet 30 flows into a flushing water channel 58 , The flushing water channel 58 runs parallel to the input channel 40 vertically from top to bottom through the housing 12 , The flushing water channel 58 is branched. In the present embodiment, the flushing water channel 58 in two levels lateral, diametrically opposite branches 60 and 62 on. The branches 60 and 62 have openings in the region of the filter material. The flow thus runs out of the flushing water channel 58 into the interior of the filter material 54 , This causes a strong turbulence of the filter material. Dirt particles are thereby released from the filter material and taken with the flow. The rinse water with the dirt particles passes down through the sieve 50 in the ground area 42 and from there via the flushing water outlet 36 out of the case 12 out. The rinse water is then disposed of, for example, in the sewer.

The rinse water inlet 22 is laterally in the upper area of the housing 12 provided and flows over a curvature 64 down into the substantially vertical flushing water channel 58 , This is in 8th again shown in detail. The ventilation opening 34 is with the flushing water channel 58 aligned in the connection fitting 20 intended. The ventilation opening 34 is via a ventilation duct 66 with the flushing water channel 58 connected. In the ventilation duct 66 is an inward opening non-return valve 68 arranged. So there is no water through the ventilation opening 34 escape.

When flushing water is passed from the flushing water inlet through the housing as described above, air will pass through the ventilation hole 34 in the flushing water channel 58 , The filter material 54 is accordingly flowed through not only with rinse water, but with a rinse water-air mixture. As a result, a particularly good turbulence and cleaning effect is achieved.
