Biological aquarium filter

The present invention includes a "biologically operating" aquarium filter for mounting in the aquarium. A filter that, like many others, | was constructed as a tube filter. This usually consists of a j inner filter sieve tube (9), an outer filter sieve tube (11) and the f

intermediate filter material (10). The two pipes and the

through the enclosed filter space are through the upper (4) and lower I.

End plate (12) formed. \

Conventionally, a mammoth j

Pump, that is, a pump which, by entering air, pressure in the water ^]

siphon tube is generated and in this way the contaminated aquarium ^water:;

sucks over the outer filter sieve tube (11) and it through the mammoth pump j

back into the aquarium. j

The disadvantage of this construction known per se is that the oxygen-poor, dirty water is sucked into the filter material, i.e. water that lacks the oxygen necessary for the biological function of the filter. ι

It is the object of this invention to put the dirty aquarium water first]

by means of the vent (13) located in the water siphon space (8) ^,! enriching with oxygen, this is done in a simple way by

that the water lifting effect achieved by the addition of air is used for this purpose 1

is used to remove the oxygen-enriched, polluted aquarium water {

now in the opposite direction, namely from the inner filter sieve tube (9), S.

to be fed to the filter material (10) in order to remove it after the dirt \

particles flow back into the aquarium through the outer filter sieve tube (11) i

allow. j

Long-term tests have shown that in this way the biological function \

could be increased considerably; the water values measured by us

are clearly better compared to conventional filters. j

So far it has been a particular difficulty in lake water, biological; Insert filter. On the one hand, the has replaced im for 15 years
Commercially available protein skimmers for the most part every filter system,
on the other hand, however, it was necessary for the one through the void! on effect- <.. \

conditional residual protein content to install a small additional filter. ;

It is therefore proposed according to the invention that the one described at the beginning biological pipe filter not to be provided with a sealing plate (2) at the top, but with a foam pipe (32), foam sieve (33) and To equip foam cups (34) of conventional design. In this way it is achieved that the once skimmed water flows through the filter material (10), additionally enriched with oxygen. Here, too, attempts have proven the correctness of the execution according to the Invention.

Claims (8)

I "I WoI ögjfecföV'A ^ uÄriinfi lter protection claims 1. Claim to protection ~. ■ - Biologically working aquarium filter for installation in the aquarium Filter which was conventionally constructed as a tubular filter. and from an inner filter sieve tube (9) an outer filter sieve tube (11) and the intermediate filter material (10), closed by the upper (4) and lower end plate (12). Characterized in that the water siphon space (8) in which the outflow (13) is located below, in the upper part through the sealing plate (2) is hermetically sealed; the water siphon space (8) is limited laterally by the inner filter strainer tube (9). 2. Claim to Protection As in claim 1, characterized in that the outflow (13) of the is located in the lower part of the water lift space (S), with the air transport pipe (7), the connecting hose (6) directly with the nipple (1) the sealing plate (2) is connected at the top. 3. Claim to Protection * According to claim 1, characterized in that the inner sieve-filter rphr (9) is made so long that it protrudes through the lower end plate (12) and thus in the lower part, i.e. the part that protrudes as a water inlet screen (14), used as a protective screen will. 4. Claim to Protection According to claim 1, characterized in that the upper end plate (4) is equipped with some ventilation holes (3). 5. Claim to Protection . As in claim 1, characterized in that the upper end plate (4) are provided with dovetail-like claws (5), which are able to take a continuously adjustable aquarium holder of known design. 6. Claim to Protection As in claim 1, characterized in that in the sealing plate incorporated air connection nipple (1) not vertically but at 90 ° ' Lying offset horizontally, so sipping a corner! forming, is arranged. ! ··! ": ':!:. ·'":.:. . · " 7. Claim to Protection According to claim 1 _Λ characterized in that the obei "e conclusion -, _ is equipped plate (4) with a groove (31) can be applied to the foam tube of known type (32) plugged good adhesion. 8. Right to protection , · As in claims 1, 4 and 6, characterized in that the air outlet holes (3) are located directly below the groove (31), see above that when the foam tube (32) is plugged into the groove (31), the air outlet holes (3) in the upper end plate (4) are hermetically sealed.
