Abstract

PURPOSE:To obtain purified water not containing chlorine and at the same time, mineral water best suited as a health drink by arranging activated carbon, porous water-permeable isolation member, granite porphyry and/or coral in that laminated order from the lower part to the upper part of a cylinder interior, and supplying an untreated water from the lower part. CONSTITUTION:Tap water from a tap water faucet 13 first comes into contact with activated carbon 4 padded at a bottom layer. Therefore, impurities or organic substances such as chlorine contained in tap water are adsorbed and captured by the activated carbon 4, and then removed. Next, the water now free from impurities passes through a porous water-permeable isolation member, coming into contact with granite porphyry 6 and/or a coral 7 layer. The porous water-permeable isolation member 5 has pores of such a size as not to allow passage of the activated carbon 4 and granite porphyry 6 or coral 7. For this reason, the activated carbon 4 is never mixed with granite porphyry 6 or coral 7. Consequently, the mineral portion melting out of granite porphyry 6 or coral 7 is adsorbed by the activated carbon 4 and is conducted out through an outlet pipe 15 without being diluted to a low concentration level.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for passing chlorine-sterilized water such as tap water to obtain chlorine-free purified water and producing mineral water suitable as a health drink. .

[0002]

2. Description of the Related Art Recently, in recent years,
The quality of drinking water, such as tap water, has declined considerably, and it is said that this is due to remarkable industrial development and the concentration of the population in large cities. That is, the river water, which is the source of tap water, contains a large amount of organic substances caused by domestic drainage, food industry drainage, agricultural drainage, etc., and due to this, various bacteria and algae are breeding, This is because trace amounts of harmful substances such as heavy metal ions are flowing in due to the outflow of factory wastewater into rivers.

Therefore, as measures against the above-mentioned organic polluted water, chlorine is added to tap water to kill or prevent growth of various bacteria in public water supply facilities, etc., but the contamination of the chlorine significantly impairs the taste of tap water. Moreover, the organic off-flavor is not sufficiently removed. In addition, as a countermeasure for the above-mentioned inorganic polluted water, only the factory is required to comply with the emission standard of harmful substances, and public water supply facilities rarely carry out water treatment for trace harmful substances such as heavy metal ions.

Therefore, there is a possibility that tap water has bad taste, has an offensive odor, and contains trace amounts of harmful substances such as heavy metal ions. The above circumstances are not limited to tap water using river water, but are the same in wells using groundwater.

Therefore, there are many cases in which drinking water is manufactured by improving tap water by a water purifying device for each home.
However, most conventional household water purifiers simply touch a filter medium such as activated carbon to pass raw water such as tap water, thereby removing chlorine and the like contained in tap water, Even if chlorine and the like in tap water can be removed to some extent by this, drinking water containing delicious water and moderate calcium and minerals, which are the requirements for healthy water, could not be obtained.

In order to solve the above problems, therefore, not only activated carbon but also a calcium-containing material or natural ore is packed in the filtration device, and water is passed while touching these, so that calcium is added to drinking water. Although it has been proposed to try to add minerals and minerals, the content of calcium and the like in the actually obtained drinking water was low, which was unsatisfactory.

[0007]

The present invention solves the above problems, removes trace harmful substances such as chlorine and heavy metals, improves the taste of water, and contains minerals necessary for maintaining health. (1) Activated carbon-porous porous water-permeable separating member such as pore mesh plate-bare stone and /
Alternatively, the coral is arranged in layers in the same order, and the raw water is configured to pass through from above to above each layer while contacting each layer in the above order, and a mineral water producing apparatus having a water purification function, and (2) ) Porous water-permeable shielding material-activated carbon-porous porous water-permeable separating member such as a porous mesh plate-bare stone and / or coral-porous water-permeable shielding in a vertically arranged cylinder. A mineral water producing apparatus having a water purification function, in which raw materials are arranged in layers in the same order so that raw water passes through the layers from the lower side to the upper side in the order mentioned above.

In the above-mentioned present invention, it is preferable that the activated carbon is silver-loaded activated carbon because it can prevent bacterial growth when the device of the present invention is not used. The coral is preferably fossil coral or calcined coral. Further, it is preferable that the barley stone is calcined at 800 ° C to 1100 ° C. It is preferable that the barley stone and / or coral have coarse particles on the upstream side through which the raw water passes and fine particles on the downstream side, respectively, and are packed in a cylinder. Not only does it remove harmful substances such as chlorine and heavy metal ions contained in water such as tap water, but it also produces mineral water containing a large amount of minerals, especially calcium, which are beneficial to the human body. can do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the drawings. FIG. 1 is a partially cutaway perspective view of an apparatus for producing mineral water having a tap water purification function according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the apparatus. As shown in each figure, at the lower end and the upper end in the cylinder (cylindrical body) 1, 1 ′,
Lower-end porous water-permeable shielding material 2 consisting of mesh plates, respectively
And an upper end porous water permeation shielding material 3, and between the respective shielding materials 2 and 3, in order from the bottom to the top, activated carbon (silver-added activated carbon) 4 and a porous water permeation layer composed of a mesh plate. Isolation member (mixing prevention member) 5, barley stone 6, and fossil coral 7 are packed and laminated.

In the above embodiment, the cylinder for packing the activated carbon, the barley stone, and the fossil coral is a cylinder, and the cylinder is an integrated body having a constricted portion such as 1, 1 '. This is a shape that is convenient for sandwiching the porous water-permeable separating member 5 by the mesh plate, and is not necessarily limited to this, and the cylindrical body may be a polygonal column shape, and the upper and lower sides are separate or integrated. It may be a cylinder.

The above-mentioned activated carbon (silver-added activated carbon) 4 is obtained by coating the surface of coconut shell or other activated carbon with silver, and is commercially available. However, the activated carbon is not limited to this, and activated carbon is mixed with silver foil or the like. You may use the thing. In addition, when such activated carbon is used, silver comes into contact with water to elute silver ions, but since the ions have sterilizing power, when dechlorinated water by activated carbon stays and does not flow (when the water purifier is not used). ) Has the effect of preventing the growth of bacteria in water.

The following porous water-permeable separating member 5 is for preventing the activated carbon 4 packed in the lower layer from mixing with the barley stone 6 packed therein, and Then 12
A mesh plate of No. 0 (JIS standard) adhered and held on a plastic frame 5a as shown in the drawing was used. The outer peripheral edge of the plastic frame 5a is in close contact with the constricted portion on the inner surface of the cylindrical body 1, and the porous water-permeable separating member 5 made of a mesh plate is a mesh that does not allow the activated carbon 4 particles to pass through. Therefore, the activated carbon 4 does not flow into the boiled stone 6 tank on the upstream side. 2b and 3b are sealing rings made of silicon rubber.

8 is provided on the porous water-permeable separating member 5.
The granules of barley stone 6 pre-sintered at 00 ° C to 1100 ° C are packed. The properties of bakuhanishi will be described later. Although the grain size of barley stone is arbitrary, it is desirable that relatively coarse particles are arranged in the lower layer and fine particles are packed in the upper layer, as in the fossil coral 7 described later.

Next, a fossil coral 7 is filled on the layer of the boiled stones 6. However, the fossil coral 7 has a coarse fossil coral with a diameter of about 2.8 mm to 5 mm on the layer of the boiled stone 6, and a diameter of 0.8 mm to 2.8 on it.
Fine fossil corals of about mm are packed in layers one after another. The uppermost end of the fossil coral 7 is shielded by the upper end porous water-permeable shield 3. A sealing ring 3b made of silicon rubber is provided around the outer circumference of the shielding material. The fossil coral is made of coral fossil, and contains porous lime as a main component and other trace components as described later.

The lower-end porous water-permeable shielding material 2 and the upper-end porous water-permeable shielding material 3 are 100 to 140 mesh (JIS) having the same or slightly larger or finer mesh than the porous water-permeable separating member 5. This mesh cloth is adhered and held to the plastic frames 2a and 3a in the same manner as the water-permeable separating member 5.

The above is the main part of the mineral water producing apparatus having the water purifying function of the embodiment of the present invention, and only this portion is separately manufactured as a replacement cartridge for the mineral water producing apparatus having the water purifying function of the present invention. It can also be used. Therefore, in the following, the main part is referred to as the cartridge part 100.

As described below, the cartridge portion 100 is provided upright, and allows raw water such as tap water to pass from bottom to top, that is, below the cartridge portion 100, upstream of the flow of raw water. If water is passed from top to bottom, the layers of the cartridge section must be arranged upside down. Even when the cartridge unit 100 is installed horizontally, the four layers of activated carbon should be arranged on the upstream side of the water supply.

The cartridge unit 100 is installed on the base 8 by screwing, and the front side of the cartridge unit 100 is covered with a cover 11 having a mounting port 10 for a flexible hose 9 on the upper side as shown in the drawing. It is installed as usual. Further, as shown in FIG. 1, a water hose mounting pipe 12 is opened in the lower part of the table 8, and the water hose mounting pipe 12 and the faucet 13 of the water pipe can be connected by a water hose 14. It has become. The water supply hose 14 is preferably a pressure resistant hose containing a net so that the water flow can be stopped first.

The tap water flowing from the water supply hose mounting pipe 12 has a lower-end porous water-permeable shielding material 2 of the cartridge portion 100, the inside of the cartridge portion, the upper-end porous water-permeable shielding material 3, The structure is such that it passes through the water outlet pipe 15 mounted on the upper end water-permeable shield 3 by the water pressure of the tap water.

By the way, a hollow packing (not shown) having a shape for holding the tip of the water discharge pipe 15 is provided inside the upper portion of the cover 11, and the hollow portion of the hollow packing is a mounting portion of the flexible hose. Since it is integrated with the hollow portion of the container 10, the mineral water passing through the inside of the cartridge portion and flowing out from the water discharge pipe 15 is a flexible hose provided on the upper portion of the cover 11 from the hollow packing. It passes through the mounting portion 10 and flows out to the flexible hose 9.

An apparatus for producing mineral water having a water purification function of the above construction, provided that the length of the cartridge portion 100 is 2
00mm, diameter 100mm, 500g of silver-loaded activated carbon (4) packed in a cartridge, bakuhanishi (6)
Using 100 g and 950 g of the same fossil coral (7), water was treated at a speed of 2 liters for 1 minute to improve the quality of tap water of the Tokyo Waterworks Bureau in Chuo-ku, Tokyo. The obtained water was analyzed at the Tokyo Food Technology Research Institute, Tokyo Metropolitan Food Hygiene Association, which is designated by the Minister of Health and Welfare, and the results were excellent as chlorine-free mineral water. The analysis results were as shown in Table 1 and Table 2. However, in Table 1, the measurement results of calcium and magnesium are shown in Table 2.

[0032]

[Table 1]

[0033]

[Table 2]

According to the data shown in the above tables, the content rate of calcium shows a value of 36.9 / liter, which is almost epoch-making for a mineral water production apparatus having this type of water purification function. It can be seen that the calcined barley rice stone and fossil coral used in the present invention eluted a large amount of calcium in tap water. Also potassium,
Trace amounts of substances such as magnesium are contained appropriately, while chlorine ions, heavy metal ions and organic substances are removed appropriately,
It can be seen that H is also kept weakly alkaline.

Although the operation of the present invention has been described above by taking the improvement of the quality of tap water as an example, the present invention is not limited to this, and can be implemented to improve the quality of well water and other water. Further, as in the embodiment, instead of using the water pressure of the tap water to pass the water from the bottom to the top of the cartridge part, it is possible to improve by pump water supply or by pouring water from the top part of the cartridge part and by gravity. The structure may be such that the generated water flows downward. In that case, it has already been stated that the order of the materials to be packed in the cartridge should be reversed from that in the above embodiment.

Further, the water of which the water quality is improved by the present invention is not only useful as a drinking water for maintaining the health of the human body as described above, but also useful as a drinking water for livestock and further for plants. Even with this, beneficial results are obtained. The reason is that chlorine-free, mineral-containing weakly alkaline water is necessary for the maintenance of life regardless of animal or plant, and the water activated by the present invention is
It is thought to be to activate each institution of life.

When the mineral water producing apparatus of the present invention having a water purification function is used for a long period of time and its effectiveness decreases and the amount of calcium ions eluted decreases, hot water should be passed through the apparatus. By doing so, it is possible to restore the same effect as before. This is because impurities contained in raw water are adsorbed and attached to the surface of activated carbon, barley stone and fossil coral, and those that cover the surface of each of the above materials are eluted by hot water and removed. It is believed that there is. However, if it is used for a long time in a normal household for a long time, the activated capacity of activated carbon reaches its limit, and the porous parts of barley stone and fossil coral become clogged. Therefore, the mineral water producing apparatus having the water purification function of the present invention can be used semipermanently.

The operation of the present invention will be described below by taking as an example the purification process of tap water and the mineral water production process using the apparatus of the above embodiment. As described above, tap water from the tap is passed through the cartridge portion 100 of the mineral water producing apparatus having the water purifying function of the present invention and flows out to the flexible hose 9. Therefore, the tap water
First, it comes into contact with the activated carbon (preferably silver-added) 4 packed in the lowermost layer of the cartridge unit 100 of the present invention. Therefore, impurities such as chlorine and organic substances contained in the tap water are adsorbed and captured by the activated carbon 4 and removed, so that the water becomes clean water containing no such impurities. Next, the water from which the impurities have been removed passes through the porous water-permeable separating member 5 and the barley stone 6 and / or the coral 7
Reach the layer of and touch it. Porous water-permeable separating member 5
Is a pore of a size that does not allow activated carbon and barley stone or coral to pass through, so activated carbon 4 does not mix with barred stone 6 or coral 7 and, as a result, minerals eluted from barley stone 6 or coral 7 Mineral water is not adsorbed by the activated carbon 4 and reduced in concentration, and chlorine-free mineral water sufficiently containing calcium and other minerals is discharged from the water discharge pipe 15.

[Other Details] As the barley stone, a domestic one produced from the Gifu region or a foreign one such as China may be used. Its main mineral composition is potassium feldspar, plagioclase, quartz, biotite (chlorite fossil), amphibole,
It is made of zircon, magnetite, apatite, etc. Bakuhanishi is useful for improving water quality because it has ion exchange and electrostatic adsorption effects and contains trace elements useful for the human body, and it elutes these elemental ions to make the human body healthy. It is thought to have the effect of maintaining. That is, the ion exchange action of bakuhanishi is
Heavy metals such as Hg, Pb, Cd, hexavalent Cr, and Tl have weak ionic radius and high charge, and weak activity, while the element that elutes barley stone first in water is ion with high chemical activity. Since K, Na, Ca, and Mg of the above, when heavy metal ions are present in water, these ions having high chemical activity are replaced by heavy metal ions and are eluted, and the heavy metal ions are incorporated into barite stone to form silicate. Form a complex. As a result, heavy metals harmful to the human body are removed from the tap water, and instead, minerals useful for maintaining the health of the human body are eluted into the water.

In the electrostatic adsorption action of barley stone, most of the minerals that compose barite stone have a tetrahedral structure of SiO ₄ , and the apical oxygen of the tetrahedron is positively charged. Absorbs bacteria and organic substances with a negative charge from the outside. Furthermore, bakuhanishi is roughly 4μ-1
It is known to emit far infrared rays with a wavelength of 4μ,
It is known that such far-infrared rays penetrate the deep part of the human body and have an activating effect on human body tissues, etc., so water containing such ingredients of barley stone maintains the human health and prevents aging. Is useful for.

Further, with respect to bakuhanishi, 800 ° C to 1
What was calcined at 100 ° C, especially in the above ion exchange action, electrostatic adsorption action, and trace component elution action,
All of them are excellent and are effective for use in a mineral water production apparatus having a water purification function. If the calcination temperature is lower than 800 ° C, sufficient porosity and mineral elution cannot be obtained.
Calcination at a temperature above 00 ° C is not preferable because part of the barley stone structure is melted and the porosity is closed. As with the fossil coral described below, it is desirable to arrange coarse grains in the lower layer and fine grains in the upper layer. The reason is the same as that of the fossil coral described below.

The water that has passed through the above-mentioned bourneishi then passes through the layer of fossil coral 7. As mentioned above, the fossil coral 7 has coarse particles in the lower layer and fine particles in the upper layer.
Each is arranged and packed. If similar particles were packed in the upper and lower layers, the flow of water would pass through a place with low flow resistance, such as a groundwater vein, and a water flow would occur in other parts. Since there is a possibility that there will be no such problem, the arrangement is made in this way in order to prevent this.

That is, with the arrangement of fossil corals as described above, the water flow of the tap water first hits a coarse layer of fossil coral particles, where the water flow is dispersed and then contacts the fine fossil coral particles. It will be. As a result, the flow of water will flow evenly through the entire cylindrical body 1 '. By the way, since the fossil coral 7 is made of fossil coral as described above, since it is mainly composed of porous lime, when water passes through the layer of the fossil coral 7, the contact area is reduced. Is increased, and Ca ions, which are easily absorbed and ingested by the human body, are eluted into water. The coral is preferably one that easily elutes calcium ions, and therefore, even a normal coral calcined is effective.

Between the layer of boiled stones 6 and the layer of corals 7, the upper or lower porous water-permeable material 2, 3 or the porous water-permeable separating member 5 such as a mesh cloth plate is provided. It is preferable to prevent the mixture of both layer materials by interposing a material similar to the above.

The tap water (raw water) passes through each of the above layers, and finally is led out from the water discharge pipe 15 to the flexible hose 9 through the flexible hose attachment port 10, and the user flows out from the flexible hose 9. Mineral water containing no chlorine and containing a sufficient amount of minerals such as calcium can be used as drinking water, cooking water and the like.

The activated carbon 4 is preferably coated with silver or mixed with silver foil or the like, and the silver ions eluted from the silver prevent the growth of various bacteria in tap water. While not using the mineral water production device having the water purification function of the invention,
Propagation of germs and other miscellaneous bacteria in the dechlorinated, chlorine-free water accumulated in the cartridge portion is suppressed.

[0031]

As described above, according to the present invention, activated carbon-a porous water-permeable separating member such as a pore mesh plate-bare stone and / or coral are arranged in the same order from the lower side to the upper side in the vertically arranged cylindrical body. (1) Impurities contained in raw water because the mineral water production apparatus has a water purification function and is arranged in a layered manner so that the raw water passes through the layers while contacting the layers in the above order. Is first adsorbed and captured by activated carbon and removed, and then the water passes through the porous water-permeable separating member and then flows through the layers of barley stone and fossil coral, so it is eluted from the barley stone and coral fossil. Beneficial components such as minerals are not adsorbed and captured by activated carbon again. As a result, sufficient calcium that is easily ingested by the human body, which is eluted from the above-mentioned barley stone, and trace elements that are useful as drinking water are derived as they are contained in the purified water. That's what gives you delicious water.

(2) The fossil coral and / or the barley stone are arranged in the upstream of the flow of the raw water, the coarse particles are arranged in the downstream side, and the fine particles are arranged in the downstream side. The water quality is efficiently improved because it flows while making uniform contact with the water quality improving substance.

(3) Boiled rice stones at 800 ° C to 1100 °
In the case where the present invention is carried out by using the one temporarily calcined at the temperature of C, since the activity of barley stone is increased, harmful trace substances such as heavy metals are removed more effectively, and beneficial minerals are removed. It will be eluted.

(4) In the case where the device of the present invention is made into a cartridge, if the water purification performance is deteriorated, just replace it.
Since the mineral water production apparatus having a water purification function can be restored to a completely new function, the other members of the present invention can be used semi-permanently as it is, and at the time of replacement, they can be attached to the tap of the water supply or the installation of the equipment. It is not necessary to do the above.
