Abstract

PURPOSE:To put a material for mineral water to practical use by improving the material to meet actual requirements for producing mineral water instantly or continuously and for adjusting pH, which have not been satisfied by conventional materials. CONSTITUTION:A powdered mineral, which elutes mineral, such as mineral stones and magnesium oxide is pelletized as required with a binder containing low temperature melting frit and others. Ceramic pellets, which were obtained by sintering the above pellets to a degree not to cause intra-pellet or inter-pellet fusion, are packed in a water permeable bag or container to provide a material for conditioning water.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention mineralizes water used widely in general drinking water, seasonings, liquor, other various food industries, biological culture water, etc., adjusts PH, or decalcifies. The present invention relates to a water conditioning material used as a member such as a tea bag-shaped or cartridge for a water purifier.

[0002]

2. Description of the Related Art Recently, various cartridge type water purifiers have been widely used in order to remove chlorine in water supply or to add minerals, but these are recent trends. As the above, various substances in which harmful substances are not simply removed by activated carbon or a hollow fiber membrane but coral sand or grilled fish bone powder are packed in layers and water is allowed to pass therethrough to dissolve mineral components are found.

However, in the case of such substances, not only the elution degree of minerals (particularly alkali components) cannot be controlled (controlled) at the stage of the raw material, but also the elution amount varies remarkably after the product is used, and tends to be excessive in the initial stage. On the other hand, it has a drawback that its durability is rapidly lost and its stability and durability are poor.

Also, it has been attempted to crush and granulate so-called mineral stones such as boiled stone, medio stone, purified stone, etc. in a cartridge of a water purifier (water conditioner), or to make them into a tea bag. However, under the actual conditions of use, there is a research report that the amount of mineral elution is virtually equal to each other because the time during which water is in contact with them is very short, and it is absolutely not practical. It couldn't be.
The present invention aims to solve such problems.

[0005]

[Means for Solving the Problems] The above mineral stone or mineral-eluting mineral such as magnesium oxide is pulverized to, for example, about 200 mesh, and this is kneaded with a broad-sense binder such as bentonite or clay. After forming into granules (including granules) with a granulator or spray dryer, etc., these granules are melted inside or are fused between granules so that they are not connected to each other (appropriately Porous granular ceramics by sintering (eg, at low temperature) and put it in a water-permeable bag to make a tea bag, or in a water-permeable container (gauge) to make a cartridge. It is a thing.

At this time, the following measures are taken in order to more strongly mineralize or alkalinize, in addition to simply producing mineral water. That is, magnesium oxide powdered to about 200 mesh is mixed with an appropriate amount of a binder such as clay and a small amount of low-temperature frit such as boric acid or borax, and the mixture is granulated as described above. Sinter in the same manner as described above to form porous granular ceramics, and similarly put in a water-permeable bag or container to commercialize.

In the present invention, the case where the mineral stone and magnesium oxide are mixed is also included, but in reality, the former mixture having a mixing ratio of 50 to 75% may have a high commercial value. In many cases, all of the raw materials are regarded as "main components".

Further, in any of the above cases, the total of 1 to 5
Calcium sulfite powder of about wt% can be mixed and fired, and such a product has a very high removal power for calcination.

[0009]

In the water conditioning material of the present invention, the mineral-eluting mineral is first powdered. Granulate it further. It is sintered to the extent that it remains granular and does not melt internally. If you put it in a water-permeable bag or container and immerse it in water or let it pass through, the water will be completely different from the one containing the conventional raw material, It more quickly penetrates into the grains. This is because the raw materials that have been pulverized once are not melted and are sintered together in the form of powder aggregates, and the microscopic voids therein are enormous and continuous, but the surface area there is enormous. Therefore, the elution amount of minerals there is so large that it cannot be compared with the case of simple stone grains. Also, the difference in dissolved concentration that occurs at that time becomes the energy of so-called osmotic pressure, which promotes fine water flow,
Combined with the fact that the whole is a collection of particles, the elution of minerals will be further accelerated. This, of course, is considered to have a positive effect on the uptake of chyle by calcium sulfite.

When magnesium oxide is used as a raw material, the aim is to obtain alkaline water having a desired pH, rather than simply producing mineral water.
It has been found that, when the low-temperature molten frit is used in combination with the above-mentioned ceramics, not only does it have the ability to be rapidly alkalized, but it also maintains a stable PH for a long time without becoming excessive in the initial stage. Moreover, it does not dissolve when immersed in water like conventional alkalized materials, that is, it does not melt or lose strength, so it does not cloud the water even after repeated use, and its alkaline level does not fluctuate over a long period of time. To keep.

[Example 1] 8 parts by weight of Ikuo stone powdered to 200 mesh and 2 parts by weight of the same bentonite powder were kneaded together with water and granulated with a granulator to an arbitrary particle size. 0
Bake at 00 ° C. for about 5 hours. The obtained granular material is put in a water-permeable cartridge together with other raw materials if necessary, and is put in an outer container to form a water conditioner.
