Description

Device for the metered generation of carbon dioxide for fertilizing plants in an aquarium »

Water plant! need nitrogen food and light for growth There is also a certain supply of carbonic acid. This carbonic acid is not sufficient in an aquarium with few fish and in soft water Amount available. It has to be re-fertilized.

A device is known that can accommodate a commercially available carbon dioxide cartridge can and the carbon dioxide via an adjustment valve in one in the aquarium Container leads, which makes it possible that the added amount of carbon dioxide can be washed into the water. This procedure is cumbersome, because you have to draw a dosed amount of carbon dioxide from the cartridge every day. The above invention is concerned with a device that over a longer period of time Period of time evenly and without maintenance, carbon dioxide is generated and released into the aquarium water washes in.

Based on the device described at the outset, this is done according to the invention solved in that a container 6 partially filled with limestone 12 is attached in a further vessel 1 in such a way that it is present in this vessel 1

Acid 5 into this container 6 through a tube 8 attached to the bottom of the container 6 reaches the limestone 12 and the resulting carbon dioxide through a top opening made in container 6 is directed to a diffusion chamber 15, which can be immersed in the aquarium "

An exemplary embodiment of the invention is described using a sketch.

A vessel 1, consisting of a preferably cylindrical and transparent one Tube 2, as well as a base 3 and a cover 4, are partially filled with acid 5.

Through the lid 4, a container 6 is let into the vessel 1, which extends over half immersed in the vessel 1. In the bottom 7 of the container 6 is a Introduced tube 8, which extends down to a few millimeters to the bottom 3 of the vessel. The acid ΰ, ζ.Β filled through the container 6. diluted hydrochloric acid, is also in the vessel 1 up to a marked filling level 9, which is approx. 15 mm is located above the bottom 7 of the container 6. In the lid 4 of the vessel 1 there is an opening 10 which can be closed by a plug 11.

This stopper 11 is during the filling of the vessel 1 and the container 6 removed with acid 5. A piece of limestone 12, which is placed in the container 6, is slowly dissolved by the acid 5 with the formation of carbon dioxide,

This carbon dioxide flows through a pierced stopper 13, which was pushed onto the container ό via a hose into a diffusion chamber 15, which is immersed in the carbonated water. The diffusion chamber 15 is a container with one or more walls made of gas-permeable material, e.g. PTFE or silicone film, which can also be reinforced with fabric. In the exemplary embodiment shown, the diffusion chamber 15 consists of an approximately 10 mm wide ring 16 made of plastic, which is closed at its end faces 17 with fabric-reinforced silicone 18. The hose line 14 leads radially through the plastic ring T'6. Since ir dos · the diffusion chamber can not so rapidly diffused through dip silicone layer 18 15 flowing carbon dioxide as it is produced, there is an increase in the pressure in the carbon dioxide range. This has the effect that the acid 5 located in the container 6 is displaced through the pipe 8 into the vessel 1. The acid 5 in the vessel 1 and the column of air above it act as counter pressure. When the acid 5 is pushed away from the limestone 12 by overpressure, the formation of carbon dioxide decreases, whereupon the overpressure also decreases, which causes the acid 5 to rise in the tube 8

It · ·

causes «The pressure regulates itself in such a way that only so much acid 5 gets onto the limestone 12 reaches as is necessary to maintain the pressure. At the coal " Dioxy generation forms a salt solution that is heavier than the acid 5, through the pipe 8 sinks. The production of carbon dioxide goes according to the one described Kindly continue until either the limestone 12 has completely dissolved, or the acid 5 is consumed. The device can then be operated again with a new charge will.
