Filters for aquarium

The invention relates to a filter for an aquarium, with a tubular standing in the water to be filtered! Fi Itei palet ₃ that is intended to be flowed through radially by the water to be filtered.

Particularly in army water aquariums, water preparation and water purification are of particular importance. On the one hand, the water renewal should be pushed out as long as possible can be, but on the other hand, especially in marine fish, excretions occur to a greater extent, which then appear as film-like Layer of dirt at the water level.

A filter is now to be created with which the film-like layer of dirt is removed from the water and the Filter package is to be fed so that the dirt present as solids is filtered out of the water by the filter package can be. The filter to be created should continue to have a simple, and therefore cheap, structure that is not susceptible to interference can. Furthermore, the filter should work equally well regardless of the current water level in the aquarium.

The filter according to the invention is characterized

by an upright float housing inside which the filter pack is located and one radially between the filter pack and the raw water collecting chamber and the float housing a clean water collecting space located inside the filter package, the float housing with at least one overflow is provided for incoming raw water.

In the drawing, an embodiment of the Krfindunp.spegenstandes is shown in vertical section.

The aquarium has side walls, only one of which is shown for cnwfind 1, and two podfnplatten 2 and 3, the

0S7O

intermediate space 4 is used to flood the floor of the aquarium. In the aquarium the water has the water level 5. Inside the aquarium there are bulkheads 6 and 7, through which water of different quality is separated from one another. The bulkheads 6 and 7 are provided with a seat 8 which is used to guide a float housing 9 which can be moved vertically therein. The bulkhead 7 is connected to the bottom 2 in a watertight manner, whereas the bulkhead 6 is at a distance from the bottom 2. The wall 7 is provided with an opening to which a line 10 connects, within which a pump wheel 11 is located. In the drawing to the left of the wall 6 there are two gas outlets 12 from which fine gas bubbles flow out and rise up to the surface of the water. These gas bubbles can be used for protein separation, which is known per se, but at the same time also for water movement, that is to say as an injector pump.

In addition to the aforementioned float housing 9, the filter has a perforated support tube seated vertically therein 13, a filter pack 11 located on the carrier tube and a the mesh-like hose 15 surrounding the filter package. Furthermore, a pot-shaped cover 16 is also present. The float housing 9 has two pipe sections 17 and 18, section 18 being coaxial with section 17. The seat 8 is circular, and all Components 13-18 have circular cross-sections. The Träserrohr 13 is seated firmly but manually detachable in the pipe section 18. The filter pack 14, which has been formed, for example, by winding up a filter mat, sits with its lower end in a sealing manner on a disk-shaped one Bottom 19, which is located between sections 17 and 18. The net-like hose 15 is used for the filter package 14 to hold rolled up filter mats together. The float housing 9 is therefore designed as a tube that is open at the top and has the front edge 20.

The cover 16 has a plate-shaped bottom 21, an inner tubular extension 2 2 and an outer tubular

Migen approach 23. The radially inner tubular extension 22 is slipped over the support tube 13 and has a tight fit with this but can be removed by hand. The radially outer extension 2 3 is slipped loosely over the filter pack 14 with hose 15, and presses so not on the filter package. The seat of the support tube 13 in the pipe section 18 and still the seat of the cover attachment 22 on The support tube 13 is so solid that the float housing 9 with all the components located therein is suspended from the cover 16 can be worn. For this purpose, the cover 16 is therefore gripped at the edge of the cover base 21 and can vertically out of the seat 8 and can thus be taken out of the aquarium. This unit is inserted in the aquarium in the opposite way. The approach 2 3 of the cover also has an annular marking strip 24. The one enclosed by the extension 2 3 of the cover 16 Air space 25 forms a float chamber. This creates a floating filter that moves vertically within the seat 8 is cash.

The working principle and mode of action of the floating filter explained is as follows: by appropriate vertical length of the lid attachment 23, the volume of the float chamber 2 5 is determined and thus the extent to which the floating filter is immersed in the raw water 26 to be cleaned. By appropriately cutting the approach 2 3 to length, the filter is now set so that with a new filter pack 14 when the outflow L2 is not in operation and the pump 11 is not in operation, it is so far immersed in the water 26 so that the front edge 20 of the float housing is above the water level 5. In this case it takes place no water circulation by means of the vent 12 and vane pump 11 instead. In this case the filter is also out of order no water can flow into the interior of the filter through the protruding edge 20. When the filter is in operation, the outlets are 12 and / or the vane pump 11 in operation. As a result, the pure water collecting space 2 located inside the support tube 13 becomes

connected to the suction chamber of the pump 12 and / or 11, so that the water is sucked out of the pure water collecting chamber 28. To the Balancing the forces is hereby moved the entire within the seat 8 displaceable Tilter down, so that the Front edge 20 of the float housing comes under the water level 5, so that the raw water 2 6 like a waterfall in the direction of arrow 29 over the front edge serving as an overflow 20 into Inside of the float housing 9 in its raw water collecting space 27 flows. It can be seen here that through this overflow at the front edge 20 primarily the on the Water level 5 floating layer in which the impurities are located is withdrawn. In the raw water collection chamber 27 is ε-I a water level 30, which is therefore below the water level 5. The raw water then flows from the collecting space 27 through the hose 15, the filter package 14 and the Träßerrohr 13 in the direction of the arrows 31 to the pure water collecting space 28. In the filter package 14 are the impurities present as solids filtered out of the water and retained in the filter pack 14. The pure water then flows in the direction of arrows 32, 33 and / or 34, 35. As a result of the flow resistance from the filter package 14, a level 3 6 will set in the collecting space 2 8 in the case of the pure water.

This advantageous removal of the film of dirt

at water level 5 takes place independently of the respective water level in the aquarium. Of course, the water level 5 must not get below the height of the seat 8. The one on the floating filter and Marking strips 24 attached to the cover 16 indicate when the filter pack 14 needs to be changed or cleaned, because it carries too many impurities. For this purpose, the marking strip 24 is provided with a conspicuous luminous color. if the filter pack 14 carries so many impurities that it Should be renewed or cleaned, the floating filter is heavier than due to these solids held in the filter pack 14 initially, so that for this reason alone the swimming

Mende filter is immersed deeper in the water 26. Simultaneously but the flow resistance through the filter pack 14 has also been increased, so that the floating filter is reinforced with Suction force is drawn down by the pumps 12 and / or 11. These two components make the floating filter so far immersed in the water 26 that their marking strips 2H in Water 26 comes to rest, so that the possibility is thereby given that the marking strip immersed in the water 26 24 can easily be noticed by the aquarium owner. It thus becomes an optical signal for changing the filter package 14 given.

The illustrated embodiment of the filter

is simple, cheap and not prone to failure. In the embodiment shown the overflow of the float housing is formed in a simple manner as a front edge 20 of a pipe end. At a Another embodiment not shown, the overflow could of course also through openings in the wall of the Pipe section 17 are formed. In such a case, the float housing could then be closed at the top and for formation contribute to the float chamber from the floating filter.
