Abstract

Closed external filter system for aerobic and anaerobic filtering of aquarium water.

Description

The invention relates to a closed External filter system according to claim 1.

Aquarium filters are available in different Variants, namely as internal filter, filter chamber and as external filter. Do all of them filter bacteria take advantage of the separated pollutants of the fish.

All filters can be used for cleaning purposes or open to change the filter material.

There are several in the nitrogen cycle Types of filter bacteria needed. A distinction is made between aerobic and anaerobic bacteria. The aerobic bacteria need As the name suggests, oxygen (aerobic), the anaerobic bacteria a milieu that does not contain oxygen (anaerobic).

It is known that external aquarium filters vary in their breakdown of pollutants. Initially when the filter material is clean is the flow rate of water and the associated oxygen content high, from it follows that mainly aerobic Pollutant degradation is operated.

Reduced with the contamination of the filter material the flow rate of the water and the oxygen content of the filter Water sinks. Now only anaerobic degradation is accomplished.

There is the possibility of a bioreactor install that accomplishes anaerobic pollutant degradation, however, the filter material used is from the filter bacteria consumed and the purchase of new filter material is essential.

Digestion towers produce during anaerobic filtering Digester gases absorbed by an activated carbon filter or to the Circulated air can be emitted, which is caused by the smell is not pleasant.

Very good results in aerobic pollutant degradation, has been achieved with the trickle filter. The water is oxygenated enriched and aerobic filter bacteria from. pollutants cleaned. So far, the trickle filter can only be used in the aquarium, or used in an open filter chamber.

This is for an aquarium cabinet and for aquarists, which are no devices want to have in the pool, unfavorable.

The variety of devices that are necessary around with big Fish stocking, or fish that produce many pollutants water quality and to ensure the associated filtering is very large.

Occasionally, hoses do not fit on the connectors from devices of different manufacturers.

Also the sometimes long hose connections, as far as leakproofness is concerned, due to slipping or sagging the hoses are unsafe.

The object of the invention is a External filter system to create that is more compact about a longer one Service life and over a higher one Pollutant degradation than current External filter systems.

This object is achieved by the Features of claim 1 solved.

By combining several filter devices and yours Außenrieselfilter the aquarium water is optimally filtered. The fermentation gases that arise are caught and the external filter system can be positioned anywhere become.

• – Das Außenfiltersystem ist so konzipiert, daß mehrere Filterkomponenten in einem Filtersystem vereint sind und so den Schadstoffabbau erhöhen
• – Das geschlossene Außenfiltersystem beinhaltet einen Rieselfilter.
• – Der Frischwasserablauf des Faulturms wird mit der Abluft des Rieselfilters betrieben (Lufthebeprinzip).
• – Mehrere Filterkomponenten werden über einen Injektor betrieben.
• – Die Faulgase werden aufgefangen und das Faulgasauffangsystem regelt sich selbständig.

The closed external filter system is mainly characterized in the points listed below:

• - The external filter system is designed so that several filter components are combined in one filter system and thus increase the pollutant breakdown
• - The closed external filter system contains a trickle filter.
• - The fresh water drain from the digester is operated with the waste air from the trickle filter (air lifting principle).
• - Several filter components are operated via one injector.
• - The fermentation gases are collected and the fermentation gas collection system regulates itself.

An embodiment of the invention is explained in more detail below with the aid of the drawing.

In the drawings is the closed external filter system for the aerobic and anaerobic degradation of pollutants in the aquarium water.

14 schemes

Prefilter ( 1 . 2 . 8th . 9 )

The front of the pre-filter (D) can be used for cleaning open become.

The foam filters in the foam chambers ( 21 ) can then be cleaned with little effort

The aquarium water to be cleaned is about a suction hose from the aquarium into the.

Prefilter (D, 22 ) sucked.

The shortened permeable spacer plate ( 19 ) separates the water flow and the large dirt particles inside. This increases the service life.

In the prefilter (D), the aquarium water is passed through the vertical foam chambers ( 21 ) cleaned of coarse dirt particles.

Due to its large surface, it has a longer service life guaranteed.

Then part of the aquarium water is in the pump filter (B) and the other part in the trickle filter (C) directed.

Pump filter ( 1 . 2 . 5 . 6 )

The aquarium water, which through a gap ( 20 ) gets into the pump filter, flows through an underfloor heating system and is thereby heated. Then the aquarium water runs through several filter pots ( 28 ) and the filter materials in it and is then pumped back into the aquarium ( 10 ).

The pump filter cover (B) is removable (cleaning).

Trickle filter ( 1 . 2 . 7 . 9 )

The part of the aquarium water that gets into the trickle filter (C) flows through a regulating mechanism ( 14 ) by a swimmer ( 15 ) is regulated.

If the water level rises and thus the float ( 15 ), a stopper on the float ( 15 ) is attached, the water supply from the pre (D) - to the trickle filter (C, 13 ). Less aquarium water penetrates into the trickle filter (C).

If the water level drops, the float also drops ( 15 ) with the grafting; the inflow is enlarged and more aquarium water can penetrate into the trickle filter (C).

This guarantees a constant Water level.

Is the aquarium water through the regulatory mechanism ( 14 ) flowed through a perforated tube system ( 16a ) and ( 16b ), which the aquarium water evenly, over the filter pots ( 28 ) distributed.

A vent on the floor ( 17b ), which supplies air via a diaphragm pump ( 17a ) enriches the trickle filter (C) and the aquarium water to be filtered with air.

The outflowing air rises against the direction of flow of the aquarium water.

In addition, a large part of the trickle filter (C) filled with air and thus a low water level accomplished.

The air and what it contains Promote oxygen the aerobic degradation (aerobic bacteria) of pollutants.

The cover of the trickle filter (C) is removable for cleaning purposes.

Post filter ( 1 . 3 . 4 . 6 )

After your trickle filter (C), the aquarium water gets into the secondary filter (A). If necessary, several filter materials can be placed in the filter pots ( 28 ) are used. In addition, the aquarium water, which is heavily enriched with air, separates from the air.

The air is released through the ventilation hose ( 11 ) in the injector ( 8th ) where the air is mixed with the fresh water ( 10 ) is led to the aquarium. This prevents the air from collecting in the secondary filter (A).

The aquarium water now in the pump filter (B) flows through a UV filter ( 5 ), which kills bacteria and floating algae.

The filtered aquarium water is fed through an injector ( 8th ) added to the fresh water according to the injector principle.

The cover of the post filter (A) is removable for cleaning purposes.

Digestion tower ( 1 . 2 . 3 . 10 . 11 . 12 )

In the digester tower (E and F) the aquarium water slowly flows through the filter media, in the filter pots ( 28 ).

There are anaerobic conditions, which promote anaerobic breakdown (anaerobic bacteria) of pollutants.

The fermentation gases that are created are fed through the slanted cover into the fermentation gas ventilation hose ( 24 ) headed.

The digester tower is operated with the exhaust air from the trickle filter (air lifting principle) ( 23 ).

The lid of the digester chambers (E and F) is removable for cleaning purposes.

Collection system for fermentation gases ( 13 )

The rising fermentation gases collect in the fermentation gas ventilation hose ( 24 ), the separation chamber (H3) interrupts the air lifting principle and thus prevents aquarium water from entering the digester container (H7).

If this is filled and the fermentation gas produced fills the digestion tower E and F, then it sinks in it sensitive water levels.

The float attached to the lid ( 25e ) with magnet also lowers, resulting in an interrupter contact with electronic switch-on delay ( 25a ) is activated.

This cuts off the power supply to the diaphragm pump for five seconds.

The now rising water level opens through its pressure the check valve (H4) and press the fermentation gases in the collection container (H7).

After five seconds the diaphragm pump reactivated and water production is active again.

Is the collecting container (H7) full, so this expresses due to its extension to a contact (H8), which is a warning diode lights up.

For emptying the shut-off valves (H5) are closed, the clutch (H6) open and the collecting container for fermentation gases (H7) removed and emptied outdoors.

Then the waste gas container (H7) mounted again and the shut-off valves (H5) opened.

So that no digester gases get over the float ( 25c ), there is an opening between the fermentation gas ventilation hose ( 25b ) and float chamber through which the fermentation gases are discharged.

overall system

There is a shut-off valve on the prefilter, as well as on the digester, which is convenient for cleaning purposes has the aquarium water removed from the filter system. to cleaning of the pre-filter, the front can be opened. The vent works automatically.

benefits

This filter system has a longer service life, than current External filter systems. It combines several filter components and is therefore more compact than Individual systems. The pollutant degradation is higher than with current filter systems. Its arrangement makes it more efficient.

The collection container for fermentation gases (H7) can be emptied can be used again. This saves costs and avoids waste, what the system is very ecological makes.
