産業上の利用分野
本発明は植物を栽培するための水耕栽培装置に使用する
養液への酸素供給及び殺菌装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for supplying oxygen to a nutrient solution and for sterilizing it used in a hydroponic cultivation apparatus for cultivating plants.
従来の技術
従来の水耕栽培装置は第３図、第４図に示すように養液
中への酸素供給は養液槽１及び栽培槽刷をポンプ３を使
用し養液を循環させ、その循環経路中で養液中に空気を
巻き込ませるか、養液槽１中に散気管４を設置し、エア
ーポンプ（図示せず）からの圧縮空気を養液中に細かい
気泡として噴出させる方式をとっていた。Conventional technology As shown in Figs. 3 and 4, conventional hydroponic cultivation equipment supplies oxygen to the nutrient solution by circulating the nutrient solution through the nutrient solution tank 1 and the cultivation tank plate using a pump 3. Either air is drawn into the nutrient solution in the circulation path, or a diffuser pipe 4 is installed in the nutrient solution tank 1, and compressed air from an air pump (not shown) is ejected into the nutrient solution as fine bubbles. I was taking it.
発明が解決しようとする問題点
従って何れの場合も栽培装置の寿命はポンプの寿命で決
まり、しかもそのポンプの寿命は約１年程であった。つ
まシその装置寿命も１年と短かいものであった。Problems to be Solved by the Invention Therefore, in any case, the lifespan of the cultivation device is determined by the lifespan of the pump, and the lifespan of the pump is approximately one year. The lifespan of the device was also short, only one year.
さらに従来の水耕栽培装置は栽培する植物が吸収したり
蒸散して減少した分の養液を追加するだけの方式である
ため、養液中に雑菌等が混入すると、その中で繁殖し、
ついには栽培している植物へも悪影響を及ぼすという問
題があった。Furthermore, conventional hydroponic cultivation systems simply add the nutrient solution that has been absorbed or transpired by the plants being cultivated, so if bacteria or the like gets mixed into the nutrient solution, they will breed within it.
Eventually, there was a problem that it also had a negative effect on the plants being cultivated.
本発明は上記従来の水耕栽培装置の問題点を解決し、よ
シ長寿命で且つ養液の殺菌性能を有する水耕栽培装置用
の酸素供給及び殺菌装置を提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the conventional hydroponic cultivation equipment described above, and to provide an oxygen supply and sterilization device for a hydroponic cultivation equipment that has a long service life and has the ability to sterilize nutrient solutions.
問題点を解決するための手段
本発明による酸素供給及び殺菌装置は、筒体内に電極を
相対して設け、これらの電極間に直流電圧を印加するよ
うにしたものである。そして下方から筒体内に養液が入
り、上方から出ていくようになっている。Means for Solving the Problems The oxygen supply and sterilization device according to the present invention is such that electrodes are provided facing each other in a cylindrical body, and a DC voltage is applied between these electrodes. The nutrient solution enters the cylinder from the bottom and exits from the top.
作 用
筒体内の電極に直流電圧を印加すると、養液中にはイオ
ンが存在するため養液は容易に電解され、陰極側から酸
素ガスが発生することになる。そして発生した酸素ガス
は微小気泡となって養液中を上昇するため筒体内には上
昇水流が発生する。酸素ガスは上昇しながら養液中に溶
は込み、養液へ酸素を供給することになる。且つ前記上
昇水流により電極周囲には常に新しい養液が供給される
ことになる。When a DC voltage is applied to the electrode in the working cylinder, the nutrient solution is easily electrolyzed due to the presence of ions, and oxygen gas is generated from the cathode side. Since the generated oxygen gas becomes microbubbles and rises in the nutrient solution, a rising water flow is generated inside the cylinder. The oxygen gas dissolves into the nutrient solution as it rises, supplying oxygen to the nutrient solution. Moreover, new nutrient solution is constantly supplied around the electrodes due to the rising water flow.
さらに、前記上昇水流によシ養液が電極部を通過する際
、養液中の雑菌等は陽極に電子を奪われ死滅することに
なる。つまり養液は筒体内の電極部を通過する際に殺菌
され、筒体内には前記上昇水流が生じているためこれに
より養液槽中の養液は常に殺菌作用を繰り返し受けるこ
とになる。Further, when the nutrient solution passes through the electrode section due to the rising water flow, germs in the nutrient solution are deprived of electrons by the anode and die. In other words, the nutrient solution is sterilized when passing through the electrode portion inside the cylinder, and since the above-mentioned rising water flow is generated inside the cylinder, the nutrient solution in the nutrient solution tank is constantly repeatedly subjected to the sterilization action.
実施例

際養液中の雑菌等は電極１２．１３に電子を奪われ死滅
することになる。つまり養液は殺菌されることになる。FIG. 1 shows a cylindrical body 11 in which a pair of mesh electrodes 12 and 13 are provided, which is the basic form of the oxygen supply and sterilization device according to the present invention. When a DC voltage is applied to the electrodes 12 and 13, the nutrient solution is electrolyzed, and oxygen is generated from the cathode and supplied to the nutrient solution. In addition, the generated oxygen becomes -H gas and dissolves into the solution while rising inside the cylinder 11 in the form of microbubbles, so a rising water flow is generated inside the cylinder 11, and this rising water flow provides a The nutrient solution in the liquid tank 14 passes through the electrode portions in the cylinder 11 in sequence. When passing through this electrode section, germs in the nutrient solution are deprived of electrons by the electrodes 12 and 13 and become extinct. In other words, the nutrient solution will be sterilized.

極を略水平状に配設する方式と、第２図の例のように網
状や孔を有する板状もしくは孔の無い板状の電極１２．
１３を略垂直状に配設する方式がある。There are two types of electrode shapes: net-like or plate-like electrodes with multiple holes arranged approximately horizontally, and mesh-like or plate-like electrodes with holes or no holes as shown in the example in Figure 2. Electrode 12.
There is a method of arranging 13 substantially vertically.
またこれら電極１２．１３への電源としては約１００ｍ
Ａの電流を供給できればよいので、太陽電池で十分であ
り、且つ太陽電池の方が取シ出せる電流が数十から数百
ミリアンペアに適宜調節できるため感電の危険もなくな
るという利点がある。In addition, the power supply to these electrodes 12 and 13 is approximately 100 m.
A solar cell is sufficient because it only needs to supply a current of A, and solar cells have the advantage of eliminating the risk of electric shock because the current that can be drawn can be adjusted appropriately from tens to hundreds of milliamperes.
電極材質としてカーボンや白金を使用すれば半永久的な
寿命が得られるし、ステンレス鋼でもその厚みにより５
〜７年の寿命も確保できるようになる。If carbon or platinum is used as the electrode material, a semi-permanent life can be obtained, and even stainless steel can have a

は期得できる。Effects of the Invention As described above, the oxygen supply and sterilization device of the present invention supplies oxygen obtained by electrolyzing the nutrient solution to the nutrient solution, so its life is determined by the life of the electrode. If stainless steel or platinum is used, a semi-light-lasting life can be obtained, and even if stainless steel is used, a life of 5 to 7 years can be expected depending on its thickness.
つまり本発明による酸素供給及び殺菌装置を使用した水
耕栽培装置は従来のものに比して格段に長寿命とするこ

Since the nutrient solution is sterilized as it passes through the electrode section, the nutrient solution is repeatedly sterilized and can always be maintained in a clean state.
