[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a filter for removing solids such as dust in collected rainwater, a purifier for purification / tuning, and an ozone gas generator. The present invention relates to a rainwater drinker that purifies and adjusts water suitable for drinking while rainwater passes through the space.

2. Description of the Related Art Without being blessed with rivers for obtaining domestic water,
In addition, rainwater is effectively used on small remote islands that are poor in groundwater, especially on remote islands with high rainfall. Rainwater has an advantage that it can be easily collected only by providing, for example, a gutter for collecting water on the roof or the like. Therefore, it can be said that rainwater is water that can be obtained at low cost depending on the application. Therefore, various methods of using rainwater have been proposed. For example, JP-A-62-946
No. 25 proposes a method and a device for utilizing rainwater as miscellaneous water. This device is composed of a filtration layer, a magnetic treatment device, and the like. Therefore, it is possible to remove sedimented mud in rainwater, scales of iron, lime dissolved in concrete, and the like.

Further, Japanese Patent Laid-Open No. 55-157374 proposes a rainwater purifying device in which a filter layer is provided above a storage tank. This filter layer is composed of sand layer and gravel layer soil,
Since it is composed of surface soil suitable for growing plants on its upper surface, solid matter, organic matter, etc. in the collected rainwater are filtered and purified by microorganisms in the gravel layer.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
According to the rainwater treatment device described in No. 4625,
Although there is an advantage of being able to purify rainwater to the extent that it is used as miscellaneous water, this device is used to purify rainwater collected from the floors where railroad rails are laid, platforms for getting on and off, etc. It is not possible to obtain drinking water with this device, as is evident from the fact that it is aimed at obtaining water. On the other hand, JP-A-55-1573
According to the rainwater purification device disclosed in No. 74, it is recognized that the rainwater is purified to some extent. However,
There are various problems in obtaining drinking water. For example, rainwater is already contaminated when it is collected by various bacteria floating in the air before it reaches the ground, or by bacteria accumulated on the roof, etc., but measures against these bacteria are taken. Therefore, it cannot be made into drinking water unless it is sterilized with chlorine that requires careful handling, or is subjected to boiling treatment that requires a large amount of energy. Further, in the above-mentioned JP-A-55-157374,
It is stated that rainwater is purified by microorganisms growing on the gravel layer surface and voids, but since rainwater does not circulate on the gravel layer surface and voids, some of it is purified. Only the rainwater in is purified, most rainwater is not.

As described above, rainwater has a feature that it can be obtained at low cost, but since it is soft water and does not contain minerals, it has not only a poor refreshing taste but is also unhealthy. There is also a drawback that it is not good to look because bubbles tend to form. The pH value of normal rainwater Ph is 5.6, but due to recent air pollution, the average pH value of rainwater in Japan is 5.3 and the pH value of Europe and the United States is 4.0. Rainwater having a high pH value is not preferable for daily use. The above-mentioned drawbacks cannot be solved by the technique disclosed in the above publication. However, JP-A-58-159892 proposes a method for treating fresh water obtained by dissolving minerals such as calcium in fresh water obtained by the evaporation method to obtain drinking water. According to this treatment method, fresh water can be converted into hard water. In addition, since the fresh water obtained by the evaporation method is less likely to be contaminated with solid matters such as dust and dust and foreign substances such as bacteria, drinking water can be obtained by this treatment method. However, since rainwater contains various bacteria in addition to solids such as dust and dust,
Rainwater cannot be made suitable for drinking by this treatment method of converting fresh water into hard water. In particular, organic matter is mixed in rainwater at the collecting stage, but it cannot be treated.

An object of the present invention is to provide a rainwater drinker which can obtain water suitable for drinks, which cannot be obtained by the conventional water treatment apparatus as described above, from rainwater at a low cost. . Specifically, it is possible to treat inorganic or organic dust, bacteria, etc. that are mixed in at the collecting stage, and to obtain drinking water that is rich in health and also has a refreshing taste, at a low cost, as well as mineral water. An object is to provide a beverage-making device.

[0007]

In order to achieve the above object, the present invention provides a filter for removing solid matters such as dust in collected rainwater, and a purifier for purifying / tuning.
An ozone gas generator for sterilization, which is a drink-making device adjusted to water suitable for drinking while rainwater passes between them, wherein the purifier is composed of activated fossil and a mineral-eluting material. At the same time, at least the activated fossil is supplied with ozone-blown water from the ozone gas generator. The invention according to claim 2 comprises a filter for removing solid matter such as dust and the like in the collected rainwater, a purifier for purification / conditioning, an ozone gas generator for sterilization, and a tank. A drink making device in which rainwater is adjusted to water suitable for drinking while circulating between them and at least between the purifier, the ozone gas generator and the tank, wherein the purifier is active. It is composed of a fossil and a mineral eluent, and at least the activated fossil is supplied with ozone-blown water from the ozone gas generator. The invention according to claim 3 is that the purifier according to claim 1 or 2 is one kind of porous mineral containing silicic acid anhydride, aluminum oxide as a main constituent, natural zeolite, and calcium compound. Alternatively, the invention according to claim 4 is such that the calcium compound according to claim 3 is selected from one or several kinds of aragonite-based calcium carbonate, fossil shells, and coral stones.

[0008]

As described above, the present invention is provided with a filter, a purifier, an ozone gas generator, etc., and rainwater is passed between them to be purified into water suitable for drinks, so the order of passing is a particular problem. However, first, for example, ozone gas generated by an ozone gas generator is blown into the collected rainwater. Then, bacteria in the rainwater are sterilized. In addition, organic substances are decomposed. Furthermore, it is decolorized and deodorized depending on the type of rainwater. Then, when the rainwater is passed through a filter, solid matters such as dust in the rainwater are removed. Then pour it into the purifier. Since the purifier is composed of activated fossil and mineral eluent, organic matter in rainwater is decomposed and purified by bacteria growing on activated fossil. Then, for example, calcium is dissolved from the mineral eluting material. In this way, rainwater is purified and adjusted into water suitable for drinking. According to the second aspect of the present invention, since the filter, the purifier, and the ozone gas generator are also provided with the tank, the filter removes solid matter in the rainwater and circulates at least between the tank and the purifier. Meanwhile, ozone gas is blown from the ozone gas generator. In this way, a large amount of rainwater is more completely purified and adjusted while circulating between the tank and the purifier.

[0009]

The present invention can be carried out in various forms, but it is desirable that rainwater be provided at the lower end of the roof and the rainwater be collected by this gutter. This is because the roof is generally located at a high place, is less dirty than the ground, and can collect rainwater with less impurities, which facilitates post-treatment. However,
According to the present invention, while the solid matter in rainwater is removed,
Since organic matter, oil, etc. are decomposed and purified, when rainwater becomes scarce, it can be collected from buildings on the ground, such as the gutters of roads. According to this embodiment, the collected rainwater is
It is configured to forcibly circulate between the tank, the filter, and the purifier, during which solids in rainwater are filtered and purified, and minerals such as calcium are dissolved. It By the way, the solid matter is almost completely removed by passing through the filter once, but it takes a relatively long time to decompose and purify the organic matter and dissolve the mineral content. Therefore, at the time of purification and dissolution, the filter can be bypassed to eliminate energy loss due to the filter.

The purifier has a function of decomposing and purifying organic matter contained in rainwater and dissolving minerals, and can be composed of a single tank filled with activated fossil and mineral eluent. . However, the figure shows an example in which one tank is divided into two and filled with activated fossil and mineral eluent, respectively. Various minerals can be applied to activated fossils and mineral eluents. For example, it is possible to apply one or several kinds of porous minerals containing silicic acid anhydride and aluminum oxide as main constituents including barite, natural zeolites, and calcium compounds. Further, among the minerals, calcium particularly affects the taste of drinking water, so that it is desirable to apply a calcium compound to the mineral eluting material. Examples of the calcium compound include aragonite-based calcium carbonate in which calcium dissolves relatively easily, fossil shells, and coral stones.

When rainwater is passed through or circulated in a tank filled with the above-mentioned calcium compound, calcium is dissolved in the rainwater, but a means for dissolving a large amount of calcium in a relatively short time is provided. You can also take it. For example, slaked lime may be used to release bubbles of carbon dioxide into water to cause an absorption reaction between slaked lime and carbon dioxide to dissolve minerals in rainwater.

It is desirable that ozone gas for sterilizing various bacteria in the rainwater is mixed with the rainwater before entering the activated stone. This is because a large amount of oxygen in ozone gas dissolves in rainwater, which helps the aerobic bacteria growing on activated fossils to promote purification of rainwater. Since ozone gas also has an action of promoting a chemical reaction, rainwater infused with ozone gas can be directly supplied to the mineral eluent to dissolve a large amount of mineral content in a short time. However, the above example is not shown.

An embodiment of the present invention will be described below. Figure 1
Fig. 2 is a schematic view showing a water supply system equipped with the purifying device according to the present embodiment, and Fig. 2 is a front view showing a part of the purifying device according to the present embodiment in section. As shown in FIG. 1, the water supply system includes a water collecting device 1 for collecting rainwater falling from the sky, a rainwater tank 10 for temporarily storing the collected rainwater, and a predetermined amount in the rainwater tank 10. The water purification apparatus 20 for purifying the rainwater into water suitable for drinking and the water discharge apparatus 50 for discharging the purified water are roughly configured.

The water collecting device 1 is provided with a gutter 2 for collecting rainwater that has fallen on the roof, and rainwater collected by the gutter 2 into a rainwater tank 10.
It is composed of a pipe 3 for guiding up to. And tube 3
A dust trap 4 for collecting rough dust and a solenoid valve 5 are interposed in the solenoid valve 5, and the solenoid valve 5 is controlled to open and close by signals from two long and short water level seisers 6, 7.

The rainwater tank 10 is composed of a container which is long in the vertical direction. A partition member 11 divides the chamber approximately in the middle thereof into upper and lower chambers, the lower chamber is a purification chamber 12, and the upper chamber is a storage chamber 13. Partition member 11
Is composed of a plurality of plate members 14, ..., 15 provided at a predetermined interval in the vertical direction. That is, one end of each of the plate members 14, ... Is the rainwater tank 10.
Alternately attached to the side walls of the. Further, a plurality of through holes are formed in the uppermost partition plate 15. Therefore, the rainwater in the storage chamber 13 will flow into the purification chamber 12 in a zigzag shape through the plurality of through holes. Since the partition member 11 is provided in this manner, the purification chamber 12
When purifying the rainwater, the water purified as described below in the purification chamber 12 does not deliberately mix with the unpurified rainwater in the storage chamber 13. Further, since the partition plate 15 is formed with a plurality of through holes, ozone gas, which will be described later, uniformly rises in the unpurified rainwater through these through holes.

At the upper opening of the rainwater tank 10, the lid 1 is provided.
6 is detachably provided, and two long and short water level sensors 6 and 7 are attached to the lid 16. The solenoid valve 5 in the pipe 3 is controlled to be opened and closed by these water level sensors 6 and 7, and a predetermined amount of rainwater is constantly stored in the rainwater tank 10. Further, the lid body 16 is also provided with an ozone killer 17.

As shown in FIG. 2, the purifier 20 comprises a filter 22, a purifier 35, an ozone generator 48, etc., which are housed in a box 21. The filter tank 23 of the filter 22 has a tubular shape as a whole. A flange bent horizontally to the outside is integrally formed in the opening above it, and the lid 24 is attached to the flange.
Can be removably attached via packing. A through hole to which the drainage first drainage pipe 25 is attached is opened in the bottom, and an introduction pipe 26 for supplying rainwater in the purification chamber 12 is provided on a side portion of the filtration tank 23. The introduction pipe 26 is located slightly below the intermediate height of the filtration tank 23 in this embodiment.

The filter body is a cylindrical strainer 2 inside and outside.
7 and 28, and a filter medium 29 concentrically filled between the strainers 27 and 28 as a unit. The outer diameter of the outer strainer 28 is smaller than the inner diameter of the filtration tank 23, and the inner strainer 27 is
The inner diameter is larger than the outer diameter of the drain pipe 30 described later. Therefore, when the filter body is inserted into the filter tank 23 and positioned by the spacer, and the filter tank 23 is closed with the lid body 24, the filter body is fixed at a predetermined position. , There is a predetermined gap between the outer strainer 28 and the outer circumferential surface, and the inner strainer 2
A predetermined interval is also formed between the inner peripheral surface of 7 and the outer peripheral surface of the drain pipe 30.

The lower end portion of the drainage pipe 30 has a filter tank 23.
It is attached to the bottom of the machine by any suitable means. The upper end of the drain pipe 30 extends upward, and the opening 31 has a lid 24.
And the distance between the opening 31 and the lid 24 is H. The lower end portion of the drain pipe 30 extends to the outside of the filtration tank 23 and is connected to the first drain pipe 25. A pump P for suction is provided in the first drain pipe 25. In this way, the opening 31 of the drainage pipe 30 has the lid 2
Since it extends to the vicinity of 4, the filtration tank 23
There is no such thing as an air pocket. However, in such a configuration, the water in the filtration tank 23 does not flow into the pump P when it is stopped. That is, the water in the filtration tank 23 does not serve as the starting priming water. In addition, it is impossible to prevent surging during the pressure feeding method. Therefore, in this embodiment, a plurality of small through holes 33, 33, ... Are opened in the drain pipe 30 at predetermined intervals in the vertical direction.

The purifier 35 comprises one tank 36 in this embodiment.
And a lower part is a septic tank 37, and an upper part is a mineral dissolving tank 38. That is, the discharge pipe 40 of the pump P is connected to the bottom 39 of the tank 36, and the detachable lid 41 is provided with the second drain pipe 42. Then, between the bottom 39 and the lid 41, the perforated plates 43, 43 arranged at a predetermined interval in the vertical direction to the septic tank 37.
The septic tank 37 is filled with porous activated stones, for example, barley stones 45 crushed to an appropriate size.
Like the septic tank 37, the mineral dissolving tank 38 is also composed of perforated plates 46, 46 arranged at a predetermined interval in the vertical direction, and is crushed into an appropriate size between the perforated plates 46, 46. For example, aragonite calcium carbonate,
Molten minerals 47, 47, such as shellfish and coral fossils ...
Are filled so that there is a gap above. Since there is a gap like this, the mineral melt stone 4
, 47, ... Can move in the vertical direction, and during movement, they are in frictional contact with each other to promote melting.

The ozone generator 48 is also the box body 2 in this embodiment.
1, the ozone gas generated by the ozone generator 48 is blown into the second drain pipe 42 through the gas pipe 49. The second drain pipe 42 is
It is connected to the purification room 12.

As shown in FIG. 1, the water discharge device 50 is provided with a pump 51 for raising the purified water suitable for drinks to a predetermined pressure. The suction pipe 52 of the pump 51 is connected to the purification chamber 12. The suction pipe 52 can be connected to the second drain pipe 42 to directly take out purified drinking water. Incidentally, reference numeral 5 in FIG.
Reference numerals 3, 54, 55, 56 and 59 denote solenoid valves, and these solenoid valves 53, 54, 55, 56 and 59 are controlled by the controller 60 together with the pump P described above. The discharge pipe 57 of the pump 51 is provided with, for example, an electronic calan 58. When the calan 58 is operated, the pump 51 is started and the solenoid valve described above is appropriately opened and closed so that purified and adjusted drinking water is discharged. ing.

Next, the operation of the above embodiment will be described.
Large pieces of dust are removed from the rainwater collected in the gutter 2 by the dust trap 4 and flow into the rainwater tank 10. Then, the solenoid valve 5 is opened and closed by the water level sensors 6 and 7, and a predetermined amount of rainwater is accumulated in the rainwater tank 10 as shown in FIG. In the purification device 20, even when the pump P is stopped, the rainwater in the purification chamber 12 is supplied to the filter 22 from the introduction pipe 26 and is not filtered between the filtration tank 23 and the outer strainer 27. However, inside the inner strainer 27, filtered rainwater is drained from the drain pipe 3
... through the 0 through holes 33, 33, ... And reach the pump P and accumulate at a predetermined depth. Therefore, as it is, the pump P
Can be started. Therefore, the solenoid valves 53 and 56 are closed, the solenoid valves 54 and 55 are opened, and the pump P of the purification device 20 is started. Then, the purification room 1 of the rainwater tank 10
The rainwater in 2 is sucked into the filter 22 from the water conduit 26.

The rainwater sucked flows through the filter device 22, the drain pipe 30, and the first drain pipe 25 in this order, and the purifier 3
Pumped to 5. When passing through the filter device 22, the filter material 29 captures solids. At this time, since the diameters of the through holes 33, 33, ... Of the drainage pipe 30 of the filter 22 are smaller than the suction capacity of the pump P, most of the rainwater filtered by the filter material 29 has the through holes 33, 33 ,. It is not possible to circulate through 33, .... Therefore, the water level in the filtration tank 23 gradually rises. It rises and is discharged from the open end 31 of the drain pipe 30. That is, the rainwater that has passed through the through holes 33, 33, ...
It will be drained from 0. Since the water level in the filtration tank 23 gradually rises, the air in the filtration tank 23 is pushed up by the rainwater and is discharged from the open end 31 of the drain pipe 30 together with the rainwater. When the rainwater passes through the filter material 29, solid matter having a relatively small diameter, which has not been removed by the dust trap 4, such as dust particles in the rainwater is removed. It should be noted that, even when the introduction pipe 26 is provided with the pump P and is of a pressure-feeding type, it is apparent that substantially the same operation is performed.

According to this embodiment, the drain pipe 30 has a through hole 3
3, 33, ... Are provided, a small amount of rainwater filtered by the filter medium 29 is sucked into the drainage pipe 30 through the through holes 33, 33, ..., and most of it is drained from the open end 31 of the drainage pipe 30. Therefore, air is not accumulated in the filtration tank 10. Further, the filter 22 of the present embodiment has a pump P for the first drain pipe 25.
There is no problem of priming because it is a suction type. Further, even if the introduction pipe 26 is configured to be a pumping type by interposing a pump, since the through holes 33, 33, ... Are provided,
There are no surging problems.

The reason why air does not accumulate in the filtration tank 23 and the reason why surging does not occur can not be theoretically explained, but whether such an effect can be obtained is determined by the through holes 33, 33 ,. ... hole diameter, drainage pipe 30 diameter, drainage pipe 3
It has been experimentally confirmed that this is due to a delicate relationship between the distance H and the like between the open end 31 of 0 and the inner surface of the lid 24. That is, it cannot be uniquely determined by the volume of the filtration tank 23, the diameter of the drainage pipe 30, the resistance of the filtration device 22, etc., but as a result of the experiment, a single-phase, 100V, 50W (rated) pump is used and the drainage pipe is used. The diameter of 30 is 25 mm and the distance H is 10 m
m, the diameter of the through holes 33, 33, ... (4) is 5 mm, that is, the area of the drainage pipe 30 is about 490 mm ² ,
Four through holes 33, 33, ... area of about 79mm ² of 4
When the area of each of the through holes 33, 33, ... Is about 16% of the area of the drainage pipe 30, the generation of air pockets can be suppressed and surging does not occur. For comparison, using the same pump, the distance H is set to 10 mm or more, and the through holes 33, 33, ...
As a result of an experiment in which the hole diameters of (4 holes) were also set to 5 mm or more, an air pocket was generated, a pumping noise was generated in the pump P, and surging was generated. On the contrary, when the diameter of the through holes 33, 33, ... Is reduced to about 3 mm, the pump P makes an intermittent noise. It is considered that this intermittent sound causes cavitation that shortens the life of the pump P.

A plurality of drain pipes 30, 30, ... Are provided, for example, seven rainwater supplied from one introduction pipe 26 are filtered by seven units and drained from one first drain pipe 25. Even if it did so, the same action and effect as the above-mentioned filter were obtained as a whole. Single phase, 100V, 150W
(Rated) pump, height 250 mm, eye size 150
An experiment was conducted in the same manner as the above-described filter using μ filter medium. The diameter of the drainage pipe 30 is 13 mm, the distance H is 7 and the distance H is 7 mm, the through holes 33, 33, ... {14 (7 × 2)
When the hole diameter is 5 mm, the generation of air pockets can be suppressed and surging does not occur. For comparison,
The same pump is used, the height of the filter medium is set to 500 mm, the drainage pipes 30, 30, ...
3, 33, ... are opened, the distance H is set to 10 mm or more, and the through holes 33, 33 ,. Surging also occurred.

The rainwater filtered by the filter 22 is purified by the purifier 3.
Pumped to 5. In the septic tank 37 of the purifier 35, 4
Since 5 is filled, the organic matter such as plants and oil floating in the filtered rainwater is decomposed and purified by the aerobic and anaerobic bacteria that feed mainly the organic matter on the barley stone 45. . At this time, the rainwater flows in the septic tank 37 from below against the gravity, so that the rainwater flows uniformly in the barley stones 45 and does not cause a short circuit.

The purified rainwater, that is, water, is sent to the mineral dissolving tank 38. In the mineral dissolution tank 38, mineral dissolved stones 47, 4 such as aragonite-based calcium carbonate, shell fossils, and coral fossils in which calcium is relatively easily eluted.
From 7, ..., Calcium is mainly dissolved. Acid rain is neutralized by calcium as it dissolves. Since the mineral dissolution stones 47, 47, ... Are accommodated in the mineral dissolution tank 38 with a margin, when the water flows in the mineral dissolution tank 38 from below against gravity, the mineral dissolution stones 47, 47 ,. Lift up. The lifted mineral molten stones 47, 47, ... Settle by gravity this time. Due to such movements, mineral melt stones 47, 4
.. are in frictional contact with each other and act so as to scrape the surface. Therefore, the dissolution of minerals is promoted.
Mineral is added and exits from the second drain pipe 42.

Ozone gas generated in the ozone generator 48 is blown into the purified water in the second drain pipe 42 through the gas pipe 49. Bacteria in water purified by this ozone gas are sterilized. If pigments, ammonia, etc. are mixed in the water, it will be decolorized and deodorized. Further, the ozone gas decomposes large organic substances that cannot be decomposed by the bacteria feeding on the barley stone 45. In addition, when an ozone pump is provided to inject ozone gas, aeration is promoted and the effect of ozone is further enhanced. The water into which the ozone gas is blown is returned from the second drain pipe 42 to the purification chamber 12 in the rainwater tank 10.

Rainwater is stored in the rainwater tank 10 as described above.
Inside purification chamber 12, introduction pipe 26, filter 22, drain pipe 3
0, the pump P, the discharge pipe 40, the septic tank 37, the mineral dissolving tank 38, the second drain pipe 42, and the purifying chamber 12 in the rainwater tank 10 are circulated and purified and adjusted to drinking water. The circulating time is set by the control device 60, for example. During such purification, the purification chamber 12 and the storage chamber 13 are partitioned by the partition member 11, so that purified water and unpurified rainwater are not mixed. The ozone gas separated from the water in the purification chamber 12 is used as the plate members 14, 14, ... Of the partition member 11.
It rises by bypassing the space between them and is dispersed by the plate material 15 having a plurality of through holes formed therein, and rises in the rainwater in the storage chamber 13. While rising, the rainwater in the storage chamber 13 is subjected to pretreatment such as sterilization and decomposition. Then, it is rendered harmless by the ozone killer 17 and released into the atmosphere.

The ozone gas blown into the second drainage pipe 42 partially becomes dissolved oxygen and dissolves in water. It is said that the amount of oxygen dissolved from ozone gas is larger than the amount of dissolved oxygen in the air. As described above, the water containing a large amount of oxygen is supplied to the barley stone 45 in the septic tank 37. Therefore, the reproduction of aerobic bacteria is promoted,
It is efficiently purified by this bacterium.

In FIG. 1, when the electronic calan 58 is operated, the pump 51 is turned on and the solenoid valves 53 and 59 are opened, so that the purified drinking water in the purification chamber 12 is discharged. The amount of water that has flowed out is supplied from the storage chamber 13 to the purification chamber 12 through the partition member 11. Since the unpurified rainwater is supplied to the purification chamber 12 through the partition member 11, it does not mix with the purified drinking water. In addition, purification device 2
It is also possible to stop the pump P of 0 and stop the cleaning operation. When the purification operation is stopped, there is no risk of unpurified rainwater being mixed with purified drinking water. If water continues to flow, unpurified rainwater may come out.
Therefore, a meter or the like may be provided in the discharge pipe 57 of the pump 51 to stop the pump 51 when a predetermined amount of water is discharged. When the water is directly discharged from the second drain pipe 42, even if unpurified rainwater is mixed, the purification device 20
The filter 2 is operated at least once by operating the
It is filtered in 2, treated in the purifier 35, and is blown with ozone gas for sterilization, so that safe drinking water is obtained.
