Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for removing harmful components contained in tap water in cooperation with activated carbon and ore emitting a trace amount of radiation.

[0002]

2. Description of the Related Art Conventionally, a water purifier attached to a water tap of a home or the like is a purifying agent composed of activated carbon or activated carbon and a hollow fiber membrane, etc. Adsorbs and removes components. However, in these water purifiers, it is difficult to maintain an effective purifying action for a long period of time because the purifying agent reaches an adsorption saturation state relatively quickly and causes clogging.

In order to solve such problems, there has been a proposal to prevent clogging of the purifying agent by mixing fine powder of radioactive minerals such as Fergsonite into activated carbon. 56-33781). As shown in FIG. 4, this proposal proposes a large number of activated carbon pieces (43) and oxides of radioactive elements such as radium oxide and thorium oxide in a water channel connecting the water supply port (41) and the water outlet (42). The gist is to provide a porous chamber (45) filled with a large number of radioactive ore pieces (44) containing.

With the above structure, the activated carbon piece (43) adsorbs harmful components such as chlorine, odorous components, trihalomethanes, bacteria, rust and algae to purify the water supplied from the water supply port (41). At the same time, the harmful components adsorbed on the activated carbon pieces (43) are exposed to the radiation emitted from the radioactive ore (44) and-
Decomposed and sterilized by ions. Thus, according to the above-mentioned proposed device, while purifying water, the activated carbon pieces (4
Since the adsorption function of 3) can be restored, the frequency of exchanging the purifying agent composed of the activated carbon pieces (43) and the radioactive ore (44) is reduced.

[0005]

However, in the above-mentioned proposed apparatus (see Japanese Utility Model Application No. 56-33781), among the harmful components adsorbed on the activated carbon, very small harmful components such as chlorine, odorous components, trihalomethanes and various bacteria are present. As described above, although it is decomposed and sterilized by the radiation emitted from the radioactive ore, relatively large foreign matters such as rust and algae are not decomposed by the radiation and remain adsorbed on the activated carbon. If such a large foreign substance is cumulatively adsorbed by the purifying agent, it eventually reaches an adsorption saturation state, causes clogging, and deteriorates the purifying function. When such clogging occurs, not only is it time-consuming to replace the cleaning agent, but it is also necessary to replace the cleaning agent containing expensive ore, which reduces the cost of replacing the cleaning agent. There was a problem that it would increase. There is also a problem that the rust and the like, which are harmful to the human body, are mixed in the water that has passed through the purifying agent, because the rust and the like accumulate in the purifying agent.

In order to solve the above-mentioned problems, a fibrous filter is arranged upstream of the purifying agent, and large toxic components such as rust contained in water are removed by this filter in advance, and then the purifying agent is removed. A configuration in which the cleaning work is performed by

However, in this structure, since water easily remains in the fibrous filter, when not used for a long period of time, the filter becomes a hotbed for the propagation of various bacteria, which contaminates the water passing through the filter and is extremely unsanitary. Water may be supplied.

In view of the above problems, the present invention provides a water purifier capable of reducing the frequency and cost of exchanging the purifying agent and constantly supplying sanitary purified water even when it is not used for a long period of time. It is intended.

[0009]

In order to achieve the above object, the apparatus of the present invention comprises a first water purifying section comprising a water-permeable carrier that contains radioactive ore and a filter that surrounds the carrier.

Second combination of radioactive ore and activated carbon
The water purifier was provided, and the first water purifier connected to the water supply port and the second water purifier connected to the water outlet were communicated with each other and stored in a container.

Further, the first water purifying section and the second water purifying section were housed in separate containers and the two containers were communicated with each other.

Further, the carrier of the first water purification section is formed into a cylindrical structure having a bottom and a cylindrical shape.

[0013]

With the above structure, the water supplied from the water supply port is
It passes through the carrier and the filter of the first water purification unit. This time,
The filter removes relatively large harmful components such as rust and algae in water. Subsequently, the water flows into the second water purification section, where the activated carbon adsorbs and removes relatively small harmful components such as chlorine, odorous components, trihalomethanes and various bacteria in the water. The purified water that has passed through the second water purification section flows out from the outlet. On the other hand, since the adsorbate adsorbed on the activated carbon is decomposed and sterilized by the radiation or-ions emitted by the ore, the adsorbing function of the activated carbon is restored as the purification work progresses. Further, when the water purifier is not used, the radiation emitted from the carrier containing the radioactive ore suppresses the growth of various bacteria near the filter.

Further, by accommodating the first water purification section and the second water purification section in separate containers to communicate with each other, the first water purification section and the second water purification section are increased in size, respectively, and a large amount of radioactive ore and activated carbon are collected. It becomes possible to store. The filter replacement work can be easily performed regardless of the positional relationship between the first water purification unit and the second water purification unit.

Further, by forming the support body of the first water purification section into a cylindrical structure having a bottomed cylindrical shape, the support body itself can perform a filter function. Therefore, even if the filter surrounding the carrier is downsized, harmful components such as rust can be sufficiently removed. The filter function of the carrier is easily restored by washing the carrier.

[Embodiment 1] A first embodiment of a water purifier according to the present invention will be described below with reference to FIGS. 1 and 2. This water purifier is configured by connecting a first water purification unit (1) and a second water purification unit (2) with a communication pipe (3), and each constituent element will be described in detail below.

The first water purification section (1) is made of stainless steel mesh or the like,
A carrier (4) which is formed in a cylindrical shape with both ends closed and is filled with a granular radioactive ore (4a), and a cylindrical filter (5) which surrounds the carrier (4). It consists of and. Among these, the radioactive ore (4a), for example,
A natural ore powder containing radium oxide such as fergusonite and an oxide of a radioactive element such as thorium oxide is mixed with ceramic powder and fired, and the fired product is crushed and granulated. By bringing such a radioactive ore (4a) into contact with water, the mineral content in the ore is eluted into the water to produce mineral water beneficial to the human body. On the other hand, as shown in FIG. 2, the filter (5) is formed by bending the nonwoven fabric (6) and the like in a zigzag shape in the inner and outer diameter directions to increase the filtering area, and further, opening corresponding to the central hole (7). It is configured by being sandwiched from above and below by lids (8a) and (8b) having parts. Of the lids (8a) and (8b), the upper lid (8
The opening of a) is inserted into the closing member (1) through the packing (9).
0), while the opening of the lower lid (8b) is connected to one end of the communication pipe (3). The first water purification unit (1) having such a configuration is placed on the bottom surface of the upper container (12) through the packing (11) and is pressed downward by the spring (13) to press the upper container (12). Keep it in close contact with the bottom of the. The upper container (12) is made transparent or translucent, and the water supply port (15) is attached to the top.

On the other hand, the second water purification section (2) is constituted by mixing activated carbon granules and radioactive ore formed by the same method as described above, and the inner bottom plate (17) inside the lower container (16). ) And the inner ceiling plate (18) to partition the storage chamber (19).
Further, a water outlet (21) is attached to the upper water storage chamber (20) surrounded by the upper part of the lower container (16) and the middle ceiling plate (18), and the lower part of the lower container (16) and the inner bottom plate are installed. The lower water storage chamber (22) surrounded by (17) is connected to the lower end of the communication pipe (3). Further, the inner bottom plate (17) and the inner ceiling plate (18) are appropriately provided with circulation holes (24) (24) ... Tensioned with a stainless steel net (23), etc., and the lower water storage chamber (22). And storage room (19), storage room (1
It enables the flow of water between the upper water storage chamber (20) and the upper water storage chamber (20) and prevents the activated carbon and the radioactive ore constituting the second water purification unit (2) from scattering outside the storage chamber (19).

In the water purifier having the above structure, the water supplied from the water inlet (15) permeates from the outside of the first water purifier (1) toward the inside, and the filter (5) and the carrier (4).
Through the pipe to the communication pipe (3). At this time, large-scale harmful components such as rust and algae in water are removed by the filter (5). Then, the water that has flowed down in the communication pipe (3) passes through the circulation hole (24) of the middle bottom plate (17) from the lower water storage chamber (22) and rises inside the storage chamber (19). During this rise, relatively small harmful components such as chlorine, odorous components, trihalomethane, and various bacteria in the water are adsorbed by the activated carbon of the second water purification section (2) to purify the water. On the other hand, the adsorbate adsorbed on the activated carbon is decomposed and sterilized by the radiation or −ions emitted from the radioactive ore of the second water purification section (2). The water that has passed through the second water purification section (2) is stored in the upper water storage chamber (20), and eventually overflows to flow out from the water outlet (21) to the outside.

As described above, in the device of the present invention, large harmful components such as rust are removed in advance by the filter (5) of the first water purification unit (1) and then other harmful components are removed by the second water purification unit (2). It is adsorbed and removed, and at the same time, the adsorbed material is decomposed by radiation or the like to restore the adsorption function of the second water purification section (2). Therefore, since the purifying function of the entire apparatus is restored only by replacing the filter (5) having rust or the like attached thereto, the frequency of replacement of the carrier (4) containing the expensive radioactive ore or the second purification water purification unit (2). Is reduced. Further, not only the second water purification section (2) but also the first water purification section (1) has radioactive ore (4a), and the radiation emitted by this radioactive ore (4a) always causes the first water purification section (1) to operate. ) Suppresses the propagation of various bacteria in the vicinity. Therefore, even when it is reused after not being used for a long period of time, sanitized purified water can be promptly provided without discarding water.

Further, the first water purification section (1) and the second water purification section (2) are housed in separate containers (12) and (16) to communicate with each other, whereby the first water purification section (1) and the second water purification section (2) are connected. Water Purification Department (2)
It is possible to increase the size of each of the above, so that a large amount of radioactive ore and activated carbon, or a large-sized carrier (4) and filter (5) can be provided. Therefore, the purification function can be improved, and the water purifier is suitable for places such as restaurants where a large amount of purified water is required. Moreover, when the 1st water purification part (1) and the 2nd water purification part (2) are accommodated in the same container, depending on the positional relationship of the 1st water purification part (1) and the 2nd water purification part (2), a filter (5). Although it may be difficult to perform the replacement work of the filter, by storing in separate containers (12) and (16), the filter can be used regardless of the positional relationship between the first water purification section (1) and the second water purification section (2). The replacement work of (5) can be easily performed.

Further, since the upper container (12) is made transparent or semi-transparent, the degree of contamination of the filter (5) can be easily observed from the outside, and it is easy to judge the replacement time of the filter (5).

It is possible to store not only the radioactive ore (4a) but also a mixture of the radioactive ore and activated carbon in the carrier (4).

[Second Embodiment] A second embodiment of the device of the present invention will be described below with reference to FIG. This water purifier is the first
The water purification section (1) is characterized by being constituted by a bottomed cylindrical carrier (4) containing a radioactive ore and a bag-like filter (5) enclosing the carrier (4). It is a thing. The carrier (4) is obtained by mixing the same radioactive ore as in Example 1 with a ceramic material, adding pore-forming powder (for example, sawdust, etc.) to the mixture, press-molding the mixture, and calcining it. It is formed into a porous structure that allows water to pass through due to the burning of the powder. The filter (5) is made of bag-shaped non-woven fabric or the like. The first water purification section (1) having such a structure has an opening portion in a transparent or semitransparent cylinder (27) in which a water supply port (15) is attached to one end and the other end is bent and formed in a vertical direction. Insert toward the water inlet (15) side.

In such a structure, the water supplied from the water supply port (15) passes through the first water purification section (1) in the tubular body (27). At this time, relatively large harmful components such as rust and algae contained in water are removed by the support (4) having a porous structure and the filter (5). Subsequently, the water flows into the second water purification section (2), and relatively small harmful components such as chlorine, odorous components, trihalomethanes and various bacteria are adsorbed and removed by the activated carbon. Then, the adsorbed substance adsorbed on the activated carbon is decomposed by radiation or −ions emitted from the radioactive ore of the second water purification section (2).

As described above, in the water purifier according to this embodiment,
The same effect as that of the first embodiment can be obtained. In addition, the carrier (4) is washed regularly or at any time with water to recover the purification function,
Furthermore, if the filter (5) is replaced with a new one, the purifying function of the entire apparatus can be restored. Therefore, it becomes possible to reduce the replacement frequency of the carrier (4) containing the radioactive ore or the second water purification section (2). In addition, since various bacteria do not propagate in the cylindrical body (27) when not in use, it is possible to always supply mineral water that is hygienic and beneficial to the human body.

By the way, by making the carrier (4) have a porous structure which allows water to pass through as described above, the carrier (4)
Since the filter itself functions as a filter, even if the filter (5) that surrounds the carrier is bag-shaped as described above, sufficient filtering performance can be exhibited, and harmful components such as rust can be completely removed. can do. As described above, by using the carrier (4) having the porous structure, the filter (5) can be downsized, and thus the first water purification unit (1) can be downsized, and further the entire water purifier can be downsized. become able to.

[0029]

According to the present invention, the purifying function of the entire apparatus can be restored by exchanging the filter of the first water purifying unit, so that the carrier containing the expensive ore and the second water purifying unit can be recovered. The replacement frequency can be greatly reduced. From this, it is possible to reduce the maintenance cost of the water purifier and reduce the financial burden on the user. Further, even if it is not used for a long period of time, various bacteria do not propagate in the device, which is extremely hygienic. In addition, as described above, the first water purification unit and the second water purification unit are separately provided so that harmful components are removed stepwise.
The water purification unit can have a dedicated structure suitable for each purpose. Therefore, since it is possible to use the amount of radioactive ore or activated carbon suitable for achieving the purpose of both water purification units, efficient use of these can be achieved.

Further, by storing the first water purification unit and the second water purification unit in separate containers, it is possible to increase the size of each of the first water purification unit and the second water purification unit, and thus the water purifier. A large amount of radioactive ore and activated carbon, or a large carrier,
A filter can be provided. Therefore, the purifying function of the water purifier can be improved, and it is possible to provide a large-scale water purifier suitable for restaurants and the like that require a large amount of purified water. Further, the replacement work of the filter can be easily performed.

On the other hand, by making the carrier body a cylindrical structure with a bottom, the size of the filter can be reduced, so that the size of the first water purification unit and the size of the entire water purifier can be reduced. Therefore, it becomes possible to provide a small-sized water purifier that does not interfere even if the water supply port is directly attached to the domestic water faucet.
