Description

The present invention relates to a settling filter, especially for ponds, aquariums, fish farms and / or ventilation systems with which in the preamble of Pa Tent claims 1 specified features.

From the prior art, a pond filter with a upper chamber and a lower chamber, whereby between between these two chambers, a horizontal, tight seal locking plate is provided which has several recesses having. A rectangular fil reaches into each recess terelement, the longitudinal axis of which is oriented vertically. The dirty water flowing into the upper chamber flows through the filter elements and then passes as Pure water in the lower chamber.

Such pond filters have numerous disadvantages:

On the one hand, coarse filter residues get on the horizon tale and tight barrier plate between the upper and the lower chamber.

These coarse filter residues are stored on the horizon tal and tight barrier plate between the upper and lower chamber in an increasingly higher layer, so that the filter elements after a short period of operation through this layer of mud at least partially noticeable reduction in throughput are added.

If they are on the horizontal shut-off plate layer of sludge to extend the service life of the filter should be removed to avoid this damage to the filter elements is done by hand.  

This manual cleaning process of horizontal ab Locking sludge sludge is tedious and time consuming as well as unsatisfactory from an aesthetic point of view.

In particular, the horizontal, tight shut-off plate between between the upper chamber and the lower chamber ner to the disadvantage that a visual inspection of the lower Chamber without time-consuming and tedious disassembly of the filter not possible.

A particular disadvantage of such pond filters is also to be seen in their lack of extensibility.

Because even if several filter elements are used one after the other switches are provided, only takes place in the area the front filter elements have a pronounced through flow takes place while the rear filter elements experienced almost no flow and therefore largely remain unused.

The object of the present invention is therefore the ready position of a settling filter, which essentially unlimited and uninterrupted use enables which is no tedious, time consuming and under aesthetically unsatisfactory manual Removal of filter residues required, which be is particularly quick and easy to clean, one view also check the lower area of the filter body without allows prior disassembly of the filter and a has excellent expandability.

According to the invention, this task is performed in a generic manner ß sedimentation filter by the in the characterizing part of Pa Features specified 1 solved.  

Particularly preferred embodiments are the subject of Subclaims.

Embodiments of the invention are based on the Drawings described in more detail. Show it:

Fig. 5 is a schematic plan view of a filter according to the Invention with a self-contained suction and / or pressure frame and a plurality of filter elements attached to it.

As can already be seen from FIG. 1, a settling filter according to the invention, in particular for ponds, aquariums and fish farming systems and / or ventilation systems, comprises at least one or more substantially vertically oriented filter elements.

As a rule, these filter elements ( 1 ) are connected to each other via a suction and / or pressure frame ( 2 ) which is closed in relation to the medium to be filtered, the pure water being removed from the suction and / or pressure frame ( 2 ) .

Due to this construction of the Abetzfil ters invention, the media to be filtered is forcibly guided through the filter elements ( 1 ) and subsequently through the suction and / or pressure frame ( 2 ).

An essential feature of the Absetzkam mer according to the invention is that one or more single or multi-part settling chambers ( 3 ) below the one or more filter elements ( 1 ) and at least partially below half of the suction and / or pressure frame ( 2 ) .

In general, the housing ( 17 ) of the entire filter according to the Invention is substantially integrally ausgebil det, so that it includes both the lower settling area ( 3 ) and the filter elements ( 1 ) at least slightly upwardly projecting side walls.

The provision of a settling chamber ( 3 ) below the Fil terelemente ( 1 ) and / or the suction and / or pressure frame ( 2 ) leads to the advantage that on or on the Filterele elements ( 1 ) and / or on the suction and / or pressure frame ( 2 ) deposited filter residues and / or dirt particles obey gravity under the effect of a self-cleaning effect in the settling chamber ( 3 ) and from there can be easily removed via one or more removal openings ( 15 ).

As is apparent in particular from Fig. 2, each Fil terelement ( 1 ) preferably comprises a substantially vertically or obliquely aligned, provided with recessed support tube ( 4 ). In general, a filter medium ( 5 ) with a large specific surface encloses the outer side and / or the vertically upward opening of the support tube ( 4 ) essentially completely.

The support tube ( 4 ) can for example be in the form of a Git terrohres, a perforated or slotted tube or a network tube made of plastic, metal or ceramic or combinations thereof with a substantially round, rectangular or square cross-sectional area.

In preferred embodiments, the filter medium ( 5 ) has essentially the shape of a cuboid or a cylinder which has at least one opening ( 6 ) extending along the longitudinal axis of the filter element ( 1 ) for receiving the support tube ( 4 ) in a substantially positive manner .

The opening of the substantially cuboid or zylinderför shaped filter medium ( 5 ) for substantially form-fitting reception of the support tube ( 4 ) is essentially formed with tig in the cuboid or cylinder. In general, the filter medium ( 5 ) is made of an open-pore plastic foam.

Alternatively, the central, substantially vertically aligned support tube ( 4 ) can be provided within a substantially vertically aligned and essentially cylindrical or cuboid, rigid housing ( 8 ) with a larger diameter.

In particular, Fig. 2 shows that the walls of the housing (8) for the entry of the medium to be filtered may have, for example, one or more recesses (9).

The intermediate space ( 10 ) between the support tube ( 4 ) and the housing ( 8 ) is preferably at least partially filled with an organic or inorganic filter medium ( 5 ) or with combinations thereof.

In general, the suction and / or pressure frame ( 2 ) is essentially designed in the form of a self-contained circular, fork-shaped, square, straight or rectangular pipe system or in the form of a straight or curved single pipe.

Preferably, the suction and / or pressure frame ( 2 ) is aligned horizontally in the form of a pipe system or a single pipe.

In particularly preferred embodiments, the suction and / or pressure frame in the form of a pipe system or a zelrohres upwards a rounded shape or a Cross-sectional area, which essentially one corresponds to the upright letter U or V.

Such a configuration of the suction and / or Druckrah mens leads to the advantage that residues or dirt particles self-cleaning slide down on this depositing Fil down into the settling chamber ( 3 ).

The filter elements ( 1 ) are usually directly or indirectly connected to this suction and / or pressure frame in the form of a pipe system or a single pipe and essentially at right angles or at an angle.

As can be seen in particular from FIGS. 2 and 4, the filter elements ( 1 ) can be plugged, snapped, screwed, glued or welded, for example via a tube angle ( 11 ) or via a tube flange with the suction and / or pressure frame ( 2 ) stay in contact.

Fig. 4 shows that in the case of an opposite supply of two pipe angles ( 11 ) on the suction and / or pressure frame ( 2 ), for example, a connecting pipe ( 12 ) through both opposite pipe angle connection openings ( 19 ) of the suction and / or pressure frame ( 2 ) protrudes and, if necessary, at least slightly projects beyond the outer wall of the suction and / or pressure frame towards the outside in order to put on the pipe angles ( 11 ) or the pipe flanges.

The connecting pipe ( 12 ) preferably has one or more recesses ( 13 ) within the suction and / or pressure frame ( 2 ) for the entry of the medium to be filtered into the suction and / or pressure frame ( 2 ).

To carry out a particularly simple and quick and convenient and clean cleaning of the filter media ( 5 ), for example a tubular device ( 14 ) for the introduction of a back-flushing medium acting on the filter element ( 1 ) on the suction and / or pressure frame ( 2 ) or ruled out be connectable to it (see Fig. 1).

Figs. 1 and 3 to 5 show that the settling chamber (3) is designed for example funnel-shaped and one or more Schmutzwasserablässe (15) has.

Preferably, the Schmutzwasserablässe (15) are provided in Wesent union at the tiefliegendsten place of the settling chamber (3) so that wasserablässe by a simple opening of the dirt (15) is a convenient, fast and hygienic disposal of filter residues from the inventive settling filter is possible. The dirty water drains ( 15 ) can be designed, for example, in the form of large cocks, slides or flaps.

In order to keep the flow velocity within the settling filter according to the invention as low as possible and to make the residence time of the medium to be filtered in the filter element as long as possible and to increase the effectiveness of the filter elements ( 1 ), the settling filter according to the invention can filter a plurality of supply lines ( 16 ) have the medium.

These supply lines ( 16 ) of the medium to be filtered are preferably provided decentrally and distributed over the dimensions of the filter body ( 17 ) (see in particular FIG. 5).

As already stated, the pure water is located within the pressure and / or suction frame ( 2 ).

Figs. 1 and 3 show that the purified water removed from the suction and / or pressure frame (2) can be effected for example by means of one or more pumps (18), which supply the pure water via one or more Reinwasserablässe (21) for further use.

As a rule, the fill level ( 20 ) of the medium to be filtered in the heel filter body ( 17 ) is at least somewhat higher than the upper end of the filter elements ( 1 ).

This complete coverage of the filter element ( 1 ) provides a particularly large usable filter surface for filter purposes. The flow rate within the filter element is therefore very low and, due to the long residence time of the medium to be filtered, allows a particularly effective biological degradation of pollutants in the filter element ( 1 ).

As can be seen in particular from FIGS. 3 and 5, a particular advantage of the settling filter according to the invention lies in the fact that it can be expanded essentially as desired and that each expansion unit contributes directly to the improvement of the filter result in full and in terms of flow.

In particular, the settling filter according to the invention is quick and easy to any size and shape by simply plugging, snapping, screwing or gluing further suction and / or pressure frame components ( 2 ) - each in connection with support tubes ( 4 ) and filter elements ( 1 ) expandable.

In summary, it should be noted that thanks to the vertical alignment of the filter elements ( 1 ) on the walls of the filter elements ( 1 ), initially settling filter residues bring about a self-cleaning of the filter elements down into the actual settling chamber ( 3 ).

In this way, the entire surface of the filter element ( 1 ) is available for filtering purposes essentially without any time limit.

Due to a self-cleaning effect, manual cleaning of the filter elements ( 1 ) is essentially not necessary.

Also filter residues and / or dirt particles located on the suction and / or pressure frame ( 2 ) slide downwards into the actual settling chamber ( 3 ), thereby causing the suction and / or pressure frame ( 2 ) to self-clean, so that even one manual cleaning of the top of the suction and / or pressure frame ( 2 ) is not required.

The settling filter according to the invention deliberately does without the shut-off plate known from the prior art between upper chamber and lower chamber. This will clog the filter through the down blocking plate piling up sludge particles and filters residues avoided.

The settling filter according to the invention also offers the advantages of an optical control that can always be carried out with ease and unrestricted accessibility of the settling chamber ( 3 ).

A major advantage of the settling film according to the invention ters is also in its excellent expandability see.

The particularly low flow velocity within the filter elements ( 1 ) and thus the extremely long dwell time of the medium to be filtered in the filter element ( 1 ) allow the pollutants contained in the medium to be filtered to be almost completely broken down by the microor possibly located in the filter element ( 1 ) mechanisms.
