Description

【０００１】
【発明の属する技術分野】
この発明は、磁場を通した水を浄化して供給する、濾材の逆洗手段を設けた装置に関する。
【０００２】
【従来の技術】
従来の水質浄化装置は、濾過槽の上部から給水して降下する水を濾材で濾過する構造をとっていた。そのため、濾材が水勢で掻き乱される結果、微細なゴミが浄化水に混入しやすく、混入した微細なゴミを除去する高精度のフィルタを必要としていた。
【０００３】
又、水質を浄化する方法として濾材を用いるものが多用されている。濾材には種々のものが採用されているが、どのように優れた濾材でも、時間の経過とともに次第に浄化能力を失うので、濾材の洗浄や交換が必要となる。
【０００４】
このため、濾材の洗浄手段、即ち逆洗手段を備えた水質浄化装置があるが、従来のものは構造が複雑であるため、装置そのものが高価となるうえ、ランニングコストがかかる欠点があった。
【０００５】
【発明が解決しようとする課題】
この発明が解決しようとする課題は、磁場を通した水が活性化することを利用して、磁気処理した水を濾過して上質の浄化水を得るとともに、濾材の逆洗手段を備えたランニングコストのかからない構造にすることにある。
【０００６】
【課題を解決するための手段】
この発明は、濾過槽内に、フィルタの下方の給水室とフィルタの上方の濾過室とを形成し、濾過槽には、磁気処理器で磁力線を浴びて、磁気処理された水を給水室に送る吐出口を下向きにした給水管と、濾過室に収容した濾材で濾過された水を取り出す送水管と、濾材を攪拌する攪拌手段とを取付けたことに特徴がある。
【０００７】
【発明の実施の形態】
濾過槽が１個の場合について図１により説明すると、１は濾過槽で、底部２の上方にはステンレスネットなどのフィルタ３が着脱可能に取付けられ、底部２とフィルタ３との間には給水室４が、又、フィルタ３の上方には濾過室５が形成されている。６は濾材であって、濾過室５の上方に収容される。
【０００８】
濾材６には、ビオライト、木炭、活性炭など、鉄、マンガン、マグネシウムなどの重金属微粒子を吸着しやすく、かつ生物膜を付着させやすいものが適している。このような特性を有するものであれば、天然濾材に限られず、プラスチック製濾材も採用できる。例えば、本出願人が先に「濾材」の名称で特許出願をした（特願平９−１４５９５２）プラスチック製濾材も採用できる。この濾材は、六角筒などの多角筒の各稜線から腕板が外延されており、さらに各腕板の外縁には、腕板の延出方向と直交する外板が設けられている。そのため、極めて表面積が大きく、又、軽量、安価であるうえ、多数の微細孔を有する炭素を混入して形成すれば、強い吸着力を得ることができる。
【０００９】
７は３本の攪拌棒で、濾過槽１の上部に取付けられたモ−タＭにより回転して、濾材６を攪拌する。攪拌棒７とモ−タＭとで攪拌手段を構成する。モ−タＭを用いないで手動で攪拌棒７を回転させることもできる。又、図示例に替えて公知の攪拌手段を採用できる。
【００１０】
８は前磁気処理器で、給水管９を挟んで複数対の永久磁石が、異極を対向させてケ−ス内に固定されている。そして、ポンプＰで前磁気処理器８に送られた水、例えば地下水は、前磁気処理器８を通過する間に強力な磁力線を浴びて、磁気処理される。磁気処理された水は、イオン化するとともに、水分子が活性化する。
【００１１】
磁気処理された水は給水室４に送られ、下向きの吐出口１０によって底部２に吹き付けられたのち、濾材６が収容されている濾過室５に入る。従来の濾過槽が濾過室の上から吸水されるのと異なり、このような下からの給水はこの発明の特徴であり、底部２に水を吹き付けることにより、比重の大きいゴミを給水室４に止めて濾過室５に入れない効果があり、又、一端底部２に当たって水勢が弱まるので上から給水する場合のように濾材６を掻き乱して微細なゴミが濾過中の水に入ることがない。
【００１２】
濾過室５に送られた磁気処理されてイオン化された水のうち、陽イオン化された水の分子により、鉄、マンガン、マグネシウムなどの重金属微粒子の原子は濾材６に吸着される。重金属微粒子以外の有害物も濾材６に吸着されるうえ、濾材６に付着した生物膜によって濾過される。
【００１３】
１１は送水管で、濾過槽１の上部に取付けられ、濾過室５で濾過された浄化水は、後磁気処理器１２を経てさらに磁気処理されて、飲料水などに広く利用される。
【００１４】
なお、濾材６の逆洗は、水道水を注水管１３、送水管１１をへて濾過室５に送り、攪拌棒７を回転させて濾材６を洗浄する。洗浄により生じた汚水は、給水室４、給水管９を経て放水管１４から放出する。なお、１５は水路切替え用の三方コックである。濾材６の逆洗は２週間間毎に行う。
【００１５】
次に図２は、濾過槽を２個接続した例を示す。第１の濾過槽１で浄化した浄化水を、吐出口１０′が下向きの接続管１６で、濾過槽１と同じ構造の第２の濾過槽１′の給水室４′へ送って濾過する。第２の濾過槽１′で濾過して得られた浄化水は、図１の例とどうように、送水管１１で後磁気処理器１２で磁気処理される。２個の濾過槽１、１′で２度濾過することによって、より上質の浄化水が得られる。
【００１６】
【発明の効果】
濾過槽の下から上へ給水して濾過するので、微細なゴミが浄化水中に紛れ込むおそれがなく、高精度のフィルタを必要としないで、上質の磁気処理された浄化水が得られる。
【００１７】
構造が簡単で小型に造れるので安価であり、逆洗時以外はポンプを作動させるための電気代を要するだけのため、ランニングコストが極めて低廉である。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus provided with a backwashing means for a filter medium for purifying and supplying water through a magnetic field.
[0002]
[Prior art]
The conventional water purification device has a structure in which water falling from the upper part of the filtration tank is filtered with a filter medium. Therefore, as a result of the filter medium being disturbed by water, fine dust is likely to be mixed into the purified water, and a high-accuracy filter that removes the mixed fine dust is required.
[0003]
In addition, a method using a filter medium is often used as a method for purifying water quality. Various types of filter media are employed. However, any excellent filter media gradually loses its purification capacity with time, and thus the filter media must be washed or replaced.
[0004]
For this reason, there is a water purification device provided with a filter medium cleaning means, that is, a backwashing means. However, the conventional apparatus has a complicated structure, so that the apparatus itself is expensive and has a running cost.
[0005]
[Problems to be solved by the invention]
The problem to be solved by the present invention is that the magnetically treated water is filtered to obtain high-quality purified water by utilizing the activation of the water through the magnetic field, and the running with the backwashing means for the filter medium It is to make the structure cost-effective.
[0006]
[Means for Solving the Problems]
In the filter tank, a water supply chamber below the filter and a filter chamber above the filter are formed in the filter tank. The filter tank is subjected to magnetic lines of force by a magnetic processor, and magnetically processed water is supplied to the water supply chamber. It is characterized in that a water supply pipe with a delivery outlet facing downward, a water supply pipe for taking out the water filtered by the filter medium accommodated in the filtration chamber, and a stirring means for stirring the filter medium are attached.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The case where there is one filtration tank will be described with reference to FIG. 1. 1 is a filtration tank, and a filter 3 such as a stainless steel net is detachably attached above the bottom 2, and water is supplied between the bottom 2 and the filter 3. A chamber 4 is formed, and a filter chamber 5 is formed above the filter 3. Reference numeral 6 denotes a filter medium, which is accommodated above the filtration chamber 5.
[0008]
The filter medium 6 is suitable for easily adsorbing heavy metal fine particles such as iron, manganese, and magnesium, such as biolite, charcoal, and activated carbon, and easily attaching a biofilm. If it has such a characteristic, it will not be restricted to a natural filter medium, A plastic filter medium can also be employ | adopted. For example, it is also possible to employ a plastic filter material for which the applicant previously applied for a patent under the name of “filter medium” (Japanese Patent Application No. 9-145952). As for this filter medium, the arm plate is extended from each ridgeline of polygonal cylinders, such as a hexagon cylinder, and the outer plate orthogonal to the extending direction of an arm plate is provided in the outer edge of each arm plate. Therefore, it has a very large surface area, is light and inexpensive, and can be obtained by mixing with carbon having a large number of micropores to obtain a strong adsorption force.
[0009]
Reference numeral 7 denotes three stirring rods, which are rotated by a motor M attached to the upper part of the filtration tank 1 to stir the filter medium 6. The stirring rod 7 and the motor M constitute stirring means. The stirring rod 7 can be manually rotated without using the motor M. Moreover, it replaces with the example of illustration and a well-known stirring means is employable.
[0010]
Reference numeral 8 denotes a pre-magnetic processor, and a plurality of pairs of permanent magnets are fixed in the case with opposite poles facing each other across the water supply pipe 9. Then, the water, for example, groundwater, sent to the pre-magnetic processor 8 by the pump P is subjected to a magnetic treatment while receiving strong magnetic lines while passing through the pre-magnetic processor 8. Magnetically treated water is ionized and water molecules are activated.
[0011]
The magnetically treated water is sent to the water supply chamber 4, sprayed onto the bottom 2 by the downward discharge port 10, and then enters the filtration chamber 5 in which the filter medium 6 is accommodated. Unlike conventional filtration tanks that absorb water from the top of the filtration chamber, such water supply from the bottom is a feature of the present invention. By blowing water to the bottom portion 2, waste having a large specific gravity is supplied to the water supply chamber 4. There is an effect of stopping and not entering the filtration chamber 5, and since the water force is weakened by hitting the bottom 2 at one end, the filter medium 6 is disturbed as in the case of supplying water from above, so that fine dust does not enter the water being filtered. .
[0012]
Among the water ionized by magnetic treatment sent to the filtration chamber 5, atoms of heavy metal fine particles such as iron, manganese, and magnesium are adsorbed to the filter medium 6 by molecules of the cationized water. Hazardous substances other than the heavy metal fine particles are also adsorbed to the filter medium 6 and filtered by a biofilm attached to the filter medium 6.
[0013]
Reference numeral 11 denotes a water pipe, which is attached to the upper part of the filtration tank 1, and the purified water filtered in the filtration chamber 5 is further magnetically processed through a post-magnetic processor 12, and is widely used for drinking water and the like.
[0014]
In addition, the backwashing of the filter medium 6 is performed by feeding tap water through the water injection pipe 13 and the water supply pipe 11 to the filtration chamber 5 and rotating the stirring rod 7 to wash the filter medium 6. The sewage produced by the washing is discharged from the water discharge pipe 14 through the water supply chamber 4 and the water supply pipe 9. In addition, 15 is a three-way cock for water channel switching. The filter medium 6 is backwashed every two weeks.
[0015]
Next, FIG. 2 shows an example in which two filtration tanks are connected. The purified water purified in the first filtration tank 1 is sent to the water supply chamber 4 ′ of the second filtration tank 1 ′ having the same structure as the filtration tank 1 through the connecting pipe 16 having the discharge port 10 ′ facing downward and filtered. The purified water obtained by filtration in the second filtration tank 1 ′ is magnetically processed by the post-magnetic processor 12 in the water supply pipe 11 as in the example of FIG. By filtering twice in the two filtration tanks 1, 1 ′, higher quality purified water can be obtained.
[0016]
【The invention's effect】
Since the water is filtered from the bottom to the top of the filtration tank, fine dust is not likely to be mixed into the purified water, and high-quality magnetically treated purified water can be obtained without requiring a high-precision filter.
[0017]
Since the structure is simple and can be made small, it is inexpensive, and the running cost is extremely low because it only requires an electricity bill for operating the pump except during backwashing.
