図1は、本発明にかかる攪拌装置の一実施態様を示す図である。
加圧装置110と、気体押圧管120と、加圧装置110と気体押圧管120の間を接続する送気管130と、を備え、気体押圧管120は、送気管130が接続された側から離れる方に、攪拌されるべき液体に浸漬する浸漬長以上の長さと、その先端側に開口部121Aと又は/及び下記の開口穴121Bを有していて、気体押圧管120が、浸漬された状態で、加圧装置110により送り込んだ気体押圧管120内の気体の圧力を上昇させ、気体押圧管120内の液体の液水位を浸漬長以上下降させることで、気体を開口部121A又は/及び下記の開口穴121Bに到達させ、直後、気体が開口部121A又は/及び下記の開口穴121Bを越えた瞬間から瞬時に気体を開口部121A又は/及び下記の開口穴121Bの周囲に噴出せしめることで液体を攪拌することを特徴としている。加圧装置110から送気管130で槽の下部から気体泡を出す従来の装置では、送気管130の排気抵抗(気体が管内を移動するときの抵抗(通りにくさ))があるため攪拌効果が低下してしまうが、本願の装置では、その欠点はなくなって、気体押圧管120内に溜まっていき、開口部121A又は/及び下記の開口穴121Bのある位置即ち浸漬長だけ液水位が下がって、気体の噴出を直接抑えていた液体の膜(薄い層)を押し破って、気体押圧管120内に溜まった気体全量が一気に噴出する。この事情は、従来の装置ではないことである。
尚、本願では、明細書及び請求の範囲の請求項2から請求項13において記述する、「上向、下向」及び「内向、外向」の定義は以下のものとする。
定義:「攪拌される液体を槽に満たし、液の液面の上方から液面に直角に気体押圧管を挿入した使用状態で、槽の底面から液面に向かう方向が上向、液面から槽の底面に向かう方向が下向」とする。
FIG. 1 is a diagram showing one embodiment of a stirring device according to the present invention.
A pressurizing device 110, a gas pressing pipe 120, and an air pipe 130 connecting between the pressurizing device 110 and the gas pressing pipe 120 are provided, and the gas pressing pipe 120 is separated from the side to which the air feeding pipe 130 is connected. On the other hand, it has a length longer than the immersion length to be immersed in the liquid to be stirred, and an opening 121A and/or an opening hole 121B described below on the tip side thereof, and the gas pressing tube 120 is immersed. By increasing the pressure of the gas in the gas pressing tube 120 sent by the pressurizing device 110 and lowering the liquid level of the liquid in the gas pressing tube 120 by the immersion length or more, the gas is released to the opening 121A or / and below. Immediately after the gas reaches the opening 121B, and immediately after the gas passes through the opening 121A and/or the following opening 121B, the gas is instantaneously ejected around the opening 121A and/or the following opening 121B. It is characterized by stirring liquids. In the conventional device in which air bubbles are emitted from the lower part of the tank from the pressurizing device 110 through the air pipe 130, the stirring effect is ineffective due to the exhaust resistance of the air pipe 130 (resistance when the gas moves in the pipe (difficulty passing)). However, in the apparatus of the present application, that drawback is eliminated, and the liquid level is lowered by the position of the opening 121A and/or the following opening hole 121B, that is, the immersion length. , the liquid film (thin layer) that directly suppresses the ejection of gas is broken, and the entire amount of gas accumulated in the gas pressing tube 120 is ejected at once. This situation is not a conventional device.
In the present application, the definitions of "upward, downward" and "inward, outward" described in claims 2 to 13 of the specification and claims are as follows.
Definition: "The tank is filled with the liquid to be stirred, and the gas pressure tube is inserted perpendicular to the liquid surface from above the liquid surface. The direction from the bottom of the tank to the liquid surface is upward, and The direction toward the bottom of the tank is defined as "downward" .

攪拌力は、気体押圧管120の浸漬長の部分の容積に溜まる気体の量で決まる。
即ち、攪拌効果が、浸漬長及び浸漬長の部分の容積で決める設計ができる。
適度の時間間隔で、加圧と瞬時噴出を繰り返して攪拌を行う。尚、1-Aでは、気体押圧管120の開口部121Aとして、気体押圧管120の下部に開口穴121Bを設けている。開口穴121Bは図のように外側ほど下がる斜め穴にすると、横方向への攪拌を効果的にできる。開口穴121Bがなくとも、開口部121Aがその役目をすることができる。
1-Bには、加圧前の気体の圧力と液水位の寸法を示し、浸漬長がh0である。Hは、液槽の空間長である。1-Cでは、加圧により、液水位が浸漬長h0だけ下げられて、瞬時噴出が起こる寸前での液水位の状態における気体の圧力、液水位関係を示している。同時に、気体押圧管120の断面の面積S0と液槽の断面の面積S1も示している。1-Cの状態の直後、一気に瞬時噴出が発生し、気体押圧管120内の気体は液体側にでて、液は逆に気体押圧管120内に戻って、液水位は1-Bの状態に戻る。
The stirring power is determined by the amount of gas accumulated in the volume of the immersion length portion of the gas pressing tube 120 .
In other words, a design can be made in which the stirring effect is determined by the immersion length and the volume of the portion of the immersion length.
Stirring is performed by repeating pressurization and instantaneous jetting at appropriate time intervals. In addition, in 1-A, an opening hole 121B is provided in the lower portion of the gas pressing tube 120 as the opening 121A of the gas pressing tube 120. FIG. If the opening hole 121B is an oblique hole that descends toward the outside as shown in the figure, stirring in the lateral direction can be effectively performed. Even if there is no opening hole 121B, the opening part 121A can play the role.
1-B shows the pressure of the gas before pressurization and the dimensions of the liquid level, and the immersion length is h0. H is the spatial length of the liquid bath. 1-C shows the relationship between the gas pressure and the liquid level when the liquid level is lowered by the immersion length h0 due to pressurization and the liquid level is just before instantaneous jetting occurs. At the same time, the cross-sectional area S0 of the gas pressing tube 120 and the cross-sectional area S1 of the liquid tank are also shown. Immediately after the state of 1-C, an instantaneous jet occurs at once, the gas in the gas pushing tube 120 goes out to the liquid side, the liquid returns to the gas pushing tube 120, and the liquid water level is in the state of 1-B. back to

因みに、瞬時噴出直前の管内圧力は、使用時を外気に通じた条件で、以下の計算のようになる。
瞬時噴出直前の加圧力Paと空間圧Pは、槽内圧力P0、液水位差h0、管面積S0、
容器面積S=S1-S0、液上昇水位差h1として、(長さ単位はm、圧力単位は気圧)
槽内圧力は、槽内がフィルタを介し外気に通じている条件で、P0一定とする。
Pa=P0+0.1(h0+h1) (1)
h0S0=h1S=h1(S1-S0)
h1=h0S0/(S1-S0) (2)
計算例:P0=1気圧、S0(直径3cm)=7.07/10000m、S1(直径30cm)=700/10000m、h0=0.15m、H=0.1mとして、
h1=0.15×7.07/10000/(700/10000-7.07/10000)
=0.15×7.07/693=0.0015m⇒水位上昇は1.5mm (3)
(3)から、Pa=1+0.1(0.15+0.0015)
=1+0.1×0.1515=1+0.01515
=1.015(気圧) (4)
P0の1気圧⇒Paの1.015気圧に昇圧で噴出限界が達成できる。
By the way, the pressure inside the pipe just before the momentary ejection is calculated as follows under the condition that the air is open during use.
The pressurizing force Pa and the space pressure P just before the instantaneous jet are determined by the tank internal pressure P0, the liquid level difference h0, the pipe area S0,
Assuming the container area S = S1 - S0 and the liquid rising water level difference h1, (length unit is m, pressure unit is atmospheric pressure)
The pressure inside the tank is kept constant at P0 under the condition that the inside of the tank communicates with the outside air through a filter.
Pa = P0 + 0.1 (h0 + h1) (1)
h0S0=h1S=h1(S1-S0)
h1=h0S0/(S1-S0) (2)
Calculation example: P0 = 1 atmospheric pressure, S0 (diameter 3 cm) = 7.07/10000 m 2 , S1 (diameter 30 cm) = 700/10000 m 2 , h0 = 0.15 m, H = 0.1 m,
h1=0.15×7.07/10000/(700/10000−7.07/10000)
= 0.15 x 7.07/693 = 0.0015 m ⇒ Water level rise is 1.5 mm (3)
From (3), Pa = 1 + 0.1 (0.15 + 0.0015)
= 1 + 0.1 x 0.1515 = 1 + 0.01515
= 1.015 (air pressure) (4)
The ejection limit can be achieved by raising the pressure from 1 atm of P0 to 1.015 atm of Pa.

尚、1-Aに示す開口部121Aが全開のものに対して、1-Dに示すように、気体押圧管120の下部の底部にある開口部121Aを狭い穴にしたものをしめす。更に、1-Eでは、開口部あるなしにかかわらず、側面にある開口穴121Bを上下に2段に形成し、液***置が加圧により、上側の開口穴121B2に到達したときに、気体を開口穴121B2から噴出させ、同時に下側の開口穴121B1から液体を気体押圧管120の管内に入れる動作をさせる。このような変更案も可能である。 1-A shows that the opening 121A is fully opened, while the opening 121A at the bottom of the lower portion of the gas pressing tube 120 is narrowed as shown in 1-D. Furthermore, in 1-E, the opening holes 121B on the side are formed in two stages, regardless of whether there is an opening, and when the liquid position reaches the upper opening hole 121B2 by pressurization, the gas is released. The liquid is ejected from the opening hole 121B2, and at the same time, the liquid is put into the tube of the gas pressing tube 120 from the lower opening hole 121B1. Such modifications are also possible.

図2は、本発明にかかる攪拌装置の他の一実施態様を示す図である。
図1では、気体押圧管120が単管構成であったが、図2の2-Aにおいては、気体押圧管120は、多重管構成である。外管120Aの内部に内菅120Bが、内菅120Bの開口部121Aのある先端が外管120Aの開口部121Aのある先端と同じ高さ又は内菅120Bが外管120Aより下側に出る配置になっている方が好ましい。尚、内菅120Bの先端が外管120Aの先端より上側にあるほど、多重管の効果は低下する。
図1と同様に、気管壁下部に開口穴121Bがあってもよいし、開口穴121Bが無くとも、内菅120Bと外管120Aの間の空間がその役割をする。尚、多重管は、外管12-Aの中にある内管120Bが複数本あってもよいが、基本的には、図示のように1本で効果が達成される。
2-Bのように液槽の液体に浸漬して使う。加圧してない状態で内菅120Bの上側先端を液水位が上回るか、下に来るかは任意に選べるが、上回る位置まで浸漬する方が、液体の戻りと気体の噴出に有利になる。
FIG. 2 is a diagram showing another embodiment of the stirring device according to the present invention.
1, the gas-pressing tube 120 has a single tube configuration, but in 2-A of FIG. 2, the gas-pressing tube 120 has a multi-tube configuration. The inner tube 120B is placed inside the outer tube 120A, and the tip of the inner tube 120B with the opening 121A is at the same height as the tip of the outer tube 120A with the opening 121A, or the inner tube 120B protrudes below the outer tube 120A. It is preferable that It should be noted that the more the tip of the inner tube 120B is located above the tip of the outer tube 120A, the more the effect of the multiple tube is reduced.
As in FIG. 1, there may be an opening hole 121B in the lower part of the trachea wall, or even if there is no opening hole 121B, the space between the inner tube 120B and the outer tube 120A will play the role. Note that the multiple tubes may have a plurality of inner tubes 120B in the outer tube 12-A, but basically the effect is achieved with one tube as shown in the figure.
It is used by immersing it in the liquid in the liquid tank as in 2-B. Whether the liquid level is higher or lower than the upper tip of the inner tube 120B in a non-pressurized state can be arbitrarily selected, but immersion to the upper position is advantageous for liquid return and gas ejection.

図1の単管構成も図2の多重管構成も基本動作は同じなので、多重管構成の図を用いて、動作を図3で説明する。図3は、本発明にかかる攪拌装置の動作の一実施態様を示す図である。3-Aは、液槽に攪拌装置が配置された図である。A)は、加圧前で、太線で示す気体押圧管120内と槽内で同じ液水位である。B)は、加圧途中で、気体押圧管120内の液水位が下がり、その分、液槽の液水位は上がっている。C)は、気体押圧管120内の液水位が開口部121A又は開口穴121Bの位置まで下がった状態で、この直後には、D)のように、開口部121A又は開口穴121Bから気体が一気に周りの液体中に噴き出す瞬時噴出状態になり、暴発的な噴出で液体が攪拌される。多重管構成では、気体は、内菅120Bと外管120Aの間の空間を通って液体中に吹き出し、同時に液体は、内菅120Bの内側を通って、上に戻ると同時に槽内上部の気体を押し出して吐き出させる。多重管構成は、気体の通路と液体の通路が分かれているため、互いの間で勢いを低減する不都合がないが、単管構成では、液体が戻る方向と気体の流れの方向が逆であり、更に、液体が入ると気体の通路が狭められ、気体が通路を維持することと反対の効果があるため、気体を押し出す力は、多重管構成に比べて弱まる。その代わり、単管構成は、単純な点が利点である。 Since the basic operation is the same for the single-tube configuration of FIG. 1 and the multi-tube configuration of FIG. 2, the operation will be explained with reference to FIG. FIG. 3 is a diagram showing one embodiment of the operation of the stirring device according to the present invention. 3-A is a diagram of a stirring device arranged in a liquid tank. A) is the same liquid level in the gas pressing tube 120 indicated by the thick line and in the tank before pressurization. In B), the liquid level in the gas pressing tube 120 drops during pressurization, and the liquid level in the liquid tank rises accordingly. C) is a state in which the liquid level in the gas pressing tube 120 has fallen to the position of the opening 121A or the opening hole 121B, and immediately after this, as in D), the gas is suddenly released from the opening 121A or the opening hole 121B. It becomes an instantaneous jet state in which it jets into the surrounding liquid, and the liquid is stirred by the violent jet. In the multi-tube configuration, the gas blows out into the liquid through the space between the inner tube 120B and the outer tube 120A, and at the same time the liquid passes through the inner tube 120B and goes back up to the upper part of the tank. push out and exhale. In the multi-tube configuration, the gas passage and the liquid passage are separated, so there is no disadvantage of reducing the momentum between them, but in the single-tube configuration, the direction of liquid return and the direction of gas flow are opposite. Furthermore, liquid entry narrows the gas passageway, which has the opposite effect of maintaining the passageway, so the force pushing the gas out is weaker than in a multi-tube configuration. Instead, the single tube construction has the advantage of simplicity.

動作は、両者は同じである。3-Bには、気体押圧管120内の気体の圧力Pと液水位H、噴出量Qの時間変化を3サイクル分示す。
A)状態から加圧を開始して、液水位は、B)状態で下がっていく、C)で液水位が最下点になると、その直後D)のように瞬時噴出量Qのように気体が一気に噴き出し、元のA)状態に戻っていく。瞬時噴出量Qによって攪拌が行われる。これが繰り返される。噴出の総量は、液水位の差である浸漬長h0の部分の気体押圧管120の容積で決まり、噴出力は、圧力、従って浸漬長h0で決まり、両者が攪拌効果に寄与するので、浸漬長h0と気体押圧管120の断面も大きい方がよい。尚、加圧してない状態での液水位と内管の上端位置とは、互いに制限関係はなく、瞬時噴出量は、浸漬長(液水位差)に対応する気体押圧管120又は、多重管構造では外管120Aの容積で決まる。
Operation is the same for both. 3-B shows changes over time in the gas pressure P, the liquid level H, and the ejection amount Q in the gas pressure tube 120 for three cycles.
Pressurization is started from the state A), the liquid level drops in the state B), and when the liquid level reaches the lowest point in C), immediately after that, as in D), the gas like the instantaneous ejection amount Q erupts at once and returns to the original A) state. Stirring is performed by the instantaneous ejection amount Q. This is repeated. The total amount of ejection is determined by the volume of the gas pressing tube 120 at the immersion length h0, which is the difference in the liquid water level, and the ejection force is determined by the pressure, and therefore the immersion length h0, both of which contribute to the stirring effect. The larger the cross section of h0 and the gas pressing tube 120, the better. In addition, the liquid water level and the upper end position of the inner tube in a state without pressure are not mutually restricted, and the instantaneous ejection amount is the gas pressure tube 120 or the multi-pipe structure corresponding to the immersion length (liquid water level difference). Then, it is determined by the volume of the outer tube 120A.

That is, a guide fin 402 for guiding the gas laterally downward in the liquid is attached immediately above the opening hole 121B when the gas pressing tube 120 has a single tube configuration, and at the lower end of the outer tube 120A when the gas pressing tube 120 has a multiple tube configuration. .
4-C is common to both the single-tube configuration and the multiple-tube configuration, and the gas-pressing tube 120 is provided with a swelling portion 403 . That is, a swelling portion 403 is provided to increase the volume at the immersion position of the outer tube 120A of the gas pressing tube 120 having a single tube configuration or the gas pressing tube 120 having a multiple tube configuration. This corresponds to the fact that the total amount of jetting is determined by the volume of the immersion length h0 of the gas pressing tube 120 described above.
