Description

Translation Device for the ecologically beneficial Treatment of Water The subject matter of the present invention is a device for the ecologically beneficial treatment of small amounts of water with activat~d charcoal and eventually with strong permanent magnetic fields, particularly for kitchen and household use.

The treatment of water with activated charcoal is particu~
larly of interest where tap water is containing chlorine, ozone, dissolved contaminations, discolorations and undesired flavoring matter and/or odorous substances. It is known that these undesired contaminations can be eliminated by activated charcoal, however, it is difficult to simply perform this afterwards also in the kitchen and in the household. In order to purify the whole tap water of a household afterwards with charcoal, it is necessary to use very big and expensive char-coal filters, which furthermore have to be installed perma-nently, and furthermore have to be filled relatively often with fresh activated charcoal. Furthermore, the after-purification and the elimination of flavoring matter and odorous substances is in most cases only necessary for that part of the water which should be drunk immediately, or which is used for the preparation of beverages like coffee and tea.
This purification is also desired for the preparation of vegetables and food. Finally, there are existing very sensitive indoor plants which are sensitive to chlorine.
-The treatment of water with strong magnetic fields is also of ~;
interest because of the surface tension of the water which ; ;
will be reduced, and whereby the treated water is behaving like soft water. Therefore, it is particularly useful for the preparation of coffee and tea. Furthermore, it is of interest to prevent e.g. the calcination of coffee machines and steam ironers or at least to reduce it. `~

~ "' ' ' The object of the invention is to provide such an device for the ecologically beneficial treatment of small amounts of water with activated charcoal and, event~lally with strong permanent magneti~ fields, which is particularly suitable for use in kitchen and household, and which is inexpensive and can be applied in a simple and safe way.

The treatment of small amounts of water with strong magnetic fields is possible by using a device consisting of a water permeable pipe made of non-ferrous metal, plastic material or pipe material and a strong permanent magnet surrounding this one, or being fixed in the pipe, whereby this device is connected to a funnel. Pipe diameter or the outlet of the same have to be designed that narrow, that maximally 10 l/min can flow through, having a water column of from 10 to 50 cm.

The treatment of small amounts of water with activated char-coal is much more difficult, since cartridges filled with charcoal are either being passed by a water column of from 10 to 50 cm too slowly to get useful results, or the charcoal filters must be made that short and porous, that no suffi~
cient cleaning effect is attained.

Therefore, the device according to the invention has to solve the problem that a sufficient amountl of water can pass through a sufficient amount of activated charcoal in a suffi-ciently short time. This is not possible without application of external water pressure.

It has been found now, that the set problem, particularly with regard to the activated charcoal, can be solved in that way that a water permeable cartridge filled with granulated activated charcoal is connected to a conical connection piece made of plastic material which can be pressed manually against the outlet of a faucet. Furthermore, if necessary, the water can flow before or afterwards through a pipe made of non-ferrous metal, plastic material or hose pipe material ~ .,:

with strong permanent magnets surrounding this pipe or being attached to this pipe.
~ :
Preferably, the connection piece having externally one or more flat-spread extensions which facilitate the pressing-on of the connection piece against the outlet of the faucet. In ~ -the most simple case, this flat-spread extension is consist-ing of a disk firmly connected to the connection piece, or is consisting of two flat-spread extensions which are displaced by 180 o, and which can be pressed only by two fingers to the outlet of the faucet. ~
' ': ';
In a preferred embodiment, the inner wall of the connection ;
piece can be provided with a sealing element. As a sealing element being suitable, e.g. sealing rings which are arran-ged e.g. in the form of an annular ring, particularly in a horizontal position at the inner wall of the connection piece. The sealing element, particularly the annular ring, is favorably fixed at the inner wall, such that the annular ring does not change its position by squeezing the faucet. The fixation can be done, e.g. by adhesive bonding. However, it can be advantageously, to take-up partially the sealing ele-ment, particularly the annular ring, in correspondingly pre- ;
pared grooves at the inner wall of the connection piece, and to secure it against position changes in this way. A further preferred embodiment consists in fixing the inserted sealing ring which is lying on a pro~ecting part by a snap ring.

In another embodiment, the material of the connection piece can be, at least in the part taking up the faucet, a flexib-le, rubbery material which is enclosing elastically the faucet, and which by way of its tension is enabling a seal-ing. With this embodiment, the connection piece can also be equipped with an excrescence circulating around the inner wall and enabling a sealing of the faucet towards the connec-tion piece. The connection piece made of the flexible mate-rial, is pushed over the faucet, and the circulating excres~
, ' ' '.~ ~-. ~ . .. , :

213~2 ~ " . "~,~

cence is sealing the connection piece; after passage of e.g.
a perlator end piece of a faucet, it is sealing the faucet.
..
Due to the elastic behavior, the excrescence circulating around the inner wall, tends to come back to the equilibrium state and, due to the pressure being combined therewith, the excrescence is fitted closely to the outer wall of the faucet. Finally, also in the conical connection piece, eventually an again conical, rubbe-ry insert can be placed which, as far as it is concerned, has annular naps or recesses and thereby providing a better sealing.

The preferably conical connection piece has an angle of in- ~;
clination which on the one hand is great enough to take up outlets of faucets of different sizes, on the other hand is not that flat~ that a sufficient sealing upon pressing-on is no more possible. The angle of the cone is preferably in the range of between 30 and 85, and in the most simple case of ;
about 75. Since also faucets are existing in some countries comprising a perlator which for its part is developed in a I
conical form, the connection piece can also be designed alto~
gether in a non-conical form, i.e., then the angle can also amount to 90. However, also for such a kind of connection piece it is recommendable, to place a rubber-elastic sealing ring and to secure the same against position changes by adhe-sive bonding or by groove forming. This embodiment being very inexpensive, it can also be useful, to deliver additionally such a conical perlator. If necessary, an adaptor which can be fastened with screws thereon, can be delivered in order to use the conical perlator more universally, particularly when travelling.

Particularly reliable is a conical rubber gasket having a Shore hardness of from 40 to 75 which is provided with particular, internal sealing rings, being attached on a suitable bulb at the connection piece, and being firmly connected with a jacketed plastic ring to the connection piece, whereby the plastic ring being welded with the :
~. '': ~

_ 5 _ 2136~2~
connection piece. This welding is realized preferably by ultrasonics.

As a plastic material for the connection piece, every plastic material can be used which is unobjectionable with regard to the food act, and which has a certain elasticity. Particular~
ly suitable are polyethylene and polypropylene which further~
more can be processed by the injection mou:Lding process. If elastomers are being applied, they still have to have a suf~
ficient hardness, in order to prove a sufficient sealing upon pressing-on by hand. Also suitable are harder materials which are coated with an elastic layer.

The grained activated charcoal has preferably a grain size of between 0,1 and 1 mm. Particularly proven are grain sizes of 0,5 mm. Particularly, the reyular packing and the regular cleaning characteristics are obtained, when activated char-coal of a homogeneous grain size is used.

In order to obtain a sufficient cleaning capacity, it is favorable to dimension the cartridge in such a way that it has a greater circumference than the connection piece. Both openings, i.e. the inlet and the outlet of the cartridge are preferably closed by sieve plates which prevent a un-desired discharge of activated charcoal. Lid and bottom of the cartridge are then preferably worked out in form of very flat funnels, whereby the central bore is corresponding more or less to the diameter of the connection piece of the conical form.

A preferred embodiment having strong permanent magnets, has also a sealing element between the pipe which can take up the permanent magnet, and the cartridge which preferably can be screwed off containing the activated charcoal. This sealing element can be, e.g., an annular ring made of rubber or other elastic materials. It is also possible to make the sealing element, e.g. the sealing ring, from the same material as the .

- 6 - ~ ~ 3 ~
one to be used to seal the connection piece towards the fau~
cet. The annular ring, e.g. is firmly attached to the outer wall of the pipe taking up the permanent magnet, in the area of the pipe end which can be screwed in (for the screwing-in of the charcoal container). Thereby, the sealing element can , .
be fixed by adhesive bonding or by fitting it into a groove ~ .
.. ..
surrounding the pipe in a circumferential direction. In order to prevent the ring being pushed out into the activated charcoal cartridge during the screwing~in of the pipe taking up the permanent magnet, furthermore, an excrescence circulating around the outer wall of the pipe taking up the permanent magnet, e.g. in the form of a rib, can be arranged.
Then, the sealing element will be overlaid at the side of the thread (facing the openiny which takes up the connection piece of the pipe which takes up the permanent magnet), such ~ ;
that during the screwing-in of the pipe into the cartridge containing the activated charcoal, the sealing element will be squeezed between the opening of the activated charcoal cartridge and the excrescence which is circulating in the circumferential direction. In this case, the excrescence ~ ;
which is circulating at the outer wall of the pipe must be placed at such a distance from the pipe end which can be screwed-in into the activated charcoal cartridge, that I
sealing will be accomplished by means of the sealing element.

If the device according to the invention is consisting only of the connection piece and the cartridge, the same can be connected tightly with one another, and, eventually, they can be formed during the production process to a large extent in the form of one piece only. Then, such a device has to be provided only with the upper sieve plate, to be filled with the grained activated charcoal, to be covered by a second sieve plate, and to be connected with the lower funnel of the cartridge serving as an outlet.

to the invention additionally comprises a pipe with surroun-~ ,.

ding or attached permanent magnet, to design the cartridge as a whole in form of a replaceable cartridge.

Indeed, it is possible to provide such a cartridge with two threads, and to screw it on the one hand Wit?h the connection piece, and on the other hand with the pipe having the permanent magnet. However, for many reasons it has been found to be essentially more favorable, to arrange the pipe having the permanent magnet between the connection piece and the cartridge. With this embodiment, e.g. crystals of the hard water deposited by the magnets, can be captured by the cartridge containing activated charcoal. Eventually, also other undesired ingredients of the water can be activated, such that they are resorbed quicker and more carefully by the activated charcoal. According to the manufacturing process, such a device is preferred, since the connection piece on the one hand and the pipe on the other hand, can be-produced in the form of one piece only. Thereafter, only the permanent mag-nets must be installed. This can be done, e.g. by application of disk-shaped permanent magnets around a round pipe, or by placing rectangular magnetic bars or blocks consisting of superimposed magnetic sheets at a pipe which, e.g. is preferably worked out in a flat manner. ~hen using this embodiment, particularly much stronger magnetic fields can be applied. By this way magnetic field strengths of 2000 Gauss can be accomplished between bars of hard ferrite and a flat pipe of plastic material having a slit of from 2 to 4 mm, to allow the passage of the water. The higher the magnetic field strengths the faster and more intensive the water quality will be influenced, such that the treated water is behaving like softer water. Such a pretreated water no more deposits the solid ingredients deriving from the water hardness at the wall of the container upon heating, but is depositing them in the form of powdery crystals.
~ . ;
Therefore, the devices according to the inventi ?n make it possible by application of the pressure of the water piping, ,, 2136~.21 to treat amounts of water of between 50 ml and 5 1 in the shortest period of time, in such a way that all exigencies will be satisfied. The replaceable cartridges containing activated charcoal can purify according to the dimensioning lOo to 500 1 of water, such that they are only exhausted after several weeks or some months of use, and thereafter should be replaced. The permanent magnets do not loose their serviceability, such that they can be used during many years.

Correspondingly, devices which are designed in a greater dimension are necessary for greater amounts of water such as being necessary in hotels, restaurants and canteens. Corres~
pondingly, the magnets and the charcoal filters should also be of a larger scale. Optionally, such devices can also be connected to a bigger faucet by means of a snap or express coupling.

The water treatment with the device according to the inven-tion is very safe to the environment, since no chemicals are used. Spent cartridges containing activated charcoal can be burned without any difficulty or can be added to the garbage, particularly, if the wall of the cartridge and the filter bottoms are consisting of polyethylene and/or polypropylene.
The treatment with strong permanent magnets is also sacrifi~
cing the use of chemicals and does not lead to any problem during the waste disposal.

g Figure 2 shows a device, wherein the treatment is a combined treatment of activated charcoal and permanent magnet.

Figure 3 is showing a device in which a sealing element in the form of an annular ring, preferably of rubber, is ~ ~-arranged in the connection piece in a particularly preferred embodiment. Also possible as a sealing material are other sealing materials, preferably those made of elastic materials, as e.g. silicone plastics and other materials used in the sealing industry.

Figure 4 shows a device according to figure 3 having an additional sealing element which can be screwed in into the activated charcoal cartridge, in the region of the end of the i`
pipe taking up the permanent magnet. Thereby, a sealing ring, e.g. an annular ring made of rubber or of another elastic material, is arranged between a rib circulating around the outer wall of the pipe an the top edge of the thread o~ the activated charcoal cartridge. Thereby, a reliable sealing between the pipe taking up the permanent magnet and the cartridge containing the activated charcoal is guaranteed.

Figures 5 and 5a show a device, being parti~ularly small and manageable and, therefore, is particularly suited for taking along when travelling, in order to use the device in practically all places where potable water is disposable from pressure pipings. Since the quality of the water worldwide being very different and unstable, it is possible according to the invention to provide practically everywhere better potable water for private use. The device according to figure 5 consists of a connection piece made of a plastic material which can be pressed by hand to the outlet of a faucet, and of a water permeable cartridge filled with grained activated charcoal, whereby at least the upper part of the filling consists of coal which additionally contains mineral additives as e.g. zeolites, and the lower part of the filling ... .- . . . .

consisting of coal which additionally is impregnated with silver ions.

Figures 6 and 6a are showing a device which is suitable for common household use, and also containing the two different qualities of coal mentioned above, however, in two separated containers. These containers can again be screwed together, such that they can be changed and replaced individually.

Figures 7 and 7a are showing an embodiment of the device which has been proven successful for taking along when travelling according to figures 5 and 5a. It consists of the connection piece made of a plastic material which can he pressed-on by hand, a replaceable cartridge filled with two qualities of activated charcoal, an outlet chamber which can be screwed on, a conical rubber sleeve which is mounted on a bulb at the connection piece and being welded with the connection piece with a jacketed plastic ring. A second, narrower rubber sleeve can be delivered which can be inserted into the first rubber sleeve, in order to be also applicable to smaller faucets.

Figure 8 shows a proven embodiment of the device for house-hold use consisting of the connection piece made of a plastic material which can be pressed-on by hand, a bigger cartridge which can be screwed-on having two kinds of charcoal, and the same rubber sleeve as in figure 7.

Figure 9 shows an embodiment having one permanent magnet and applying the same cartridge which can be screwed-on, as in figure 8.

Preferably, among the coal filters also such a coal can be applied that due to certain absorbent mineral additives as silicic acid, alumina and natural or synthetic zeolites, is in the position to eliminate lead from the water. This can be of special importance in houses or municipalities, where -: . . ~ . , 2136~2~

still lead pipes or water pipes plumbed with lead solder are present which are leading to an undesired lead body burden of the water. Such a material is produced and sold, e.g. under the label ATC TM and ATS TM, e.g. by the company Engelhard.
It is impregnated onto the surface of microporous, activated charcoal granulate.

Since these mineral additives can de deactivated by silver ions, therefore, the coal filters are filled preferably with two layers of differPnt activated charcoal. The lower layer is then preferably consisting of activated charcoal which is impregnated with silver ions, whereas the upper layer is consisting of activated charcoal containing no silver ions, and instead of this, is mixed or impregnated with the mineral additives. These two layers are preferably separated by a sieve plate or a non woven fabric filter from one another.

The upper activated charcoal can as well absorb the in water dissolved cationic heavy metals like lead as eliminate the undesired ingredients, as flavoring matter, odors, chlorine and organic contaminations like pesticides and herbicides.
According to the special needs of the regions and the water being available thereabout, and the contaminations contained therein, the upper and the lower layer can be selected from an equally or differently strong size. The lower layer will preferably again be impregnated with silver ions.

Due to the costs, the cartridge can also be filled with a mixture of two different types of activated charcoal. This mixture is at least in the beginning as efficient as the two types of activated charcoal distributed in two separated parts of the cartridge. The lifetime of such cartridges is eventually somewhat shorter, since the silver ions can deactivate the mineral additives earlier.
