The present invention relates to a nozzle for generating micro-bubbles for accommodating a mixed liquid in which gas and liquid are mixed from the outside to generate micro bubbles. The present invention relates to a nozzle for generating micro bubbles for accommodating a formed liquid at a predetermined pressure and releasing the mixed liquid into fine bubbles.

In general, there are various methods of using air bubbles, and in daily life, people generally take a bath or shower to keep clean or to relieve fatigue. Scented and health-friendly foam baths are preferred, and are used for the supply of oxygen for ornamental fish farming and fish farming.

In addition, the dissolved oxygen is lowered due to the deterioration of the water quality is also used as a method for increasing this, it is used to purify and sterilize water quality or air.

As described above, various methods using bubbles are used in relation to daily life and environment, but the generation of bubbles is not easy, and the bubble efficiency is low due to the large size of bubbles generated.

In addition, in order to purify water quality and increase dissolved oxygen, bubbles are generated by using various fountains, waterfalls, and oxygen aeration in closed waters such as lakes, swamps, dams, etc., but the effects are insignificant. Expect only the effect of. This is because the size of the bubble that is put in contact with the water is large, and the degree of floating

This was because the effect of increasing the dissolved oxygen in water could not be expected.

In addition, when a gas such as oxygen (O) or ozone (O₃) is injected into and contacted with a liquid, the particle size of 0.2 to 3 mm corresponds to a large bubble, so that the contact area with the liquid is small and the floating speed of the gas is increased. It is fast and the contact time with the liquid is also short, and the gas dissolution rate into the liquid is very low.

Therefore, as an alternative to increase the gas dissolution rate into the liquid, a study in which the contact tank has a cylindrical shape and the liquid in the contact tank is rotated to increase the contact time even slightly, or an arrangement requiring more contact time of the liquid ( Although studies have been conducted to increase the effect by adding a larger amount of gas by using a batch method, the effect is insufficient for oxygen aeration in a real pond or swamp.

In addition, even if the existing waste treatment facility or the combined septic tank is aerated, the particle size of the input gas is large so that the aeration tank itself is largely secured. In addition, in the oxygen aeration of the aquaculture fishery, the particle size of the corresponding gas is similar. Due to the low melting rate of the furnace, that is, the dissolved oxygen rate cannot be enhanced, it is not possible to implement a high density farming, and there is a problem that the mortality rate due to disease or oxygen deficiency is high.

Various methods have been used to solve the above problems, and various forms of microbubble generating devices have been developed.

Such a micro bubble generator has been proposed as a "bubble dissolving device" in Korea Patent No. 10-0465756.

As shown in FIG. 1, the bubble dissolving device has a spiral swirl flow generating blade 3 formed therein so that the swirl flow generating unit 1 can generate swirl flow in the same direction inside the swirl flow tube 2. A gas inlet (4) having an adjustment valve (not shown) is formed at the tip of the swirl flow tube (2), and a swirl flow generation portion is formed at one end of the swirl flow tube (2) of the swirl flow generation unit (1). A bubble grinding tube 5 having a diameter slightly smaller than that of the swirl flow tube 2 of (1) is integrally extended, and a plurality of bubble grinding protrusions 6 are uniform on the inner surface of the bubble grinding tube 5 toward the center thereof. Are arranged.

That is, in the conventional bubble dissolving device, a mixed liquid in which a constant pressure is formed on the outside and a gas and a liquid are mixed is swirled by a swirl flow generating blade 3 provided inside the swirl flow tube 2, as described above. The bubble mixed with the liquid by the plurality of bubble grinding protrusions 6 provided in the bubble grinding tube 5 is refined.

However, in order to obtain the above effects, the bubble grinding protrusions 6 should be arranged in a pair of three at intervals of 120 ° on the side surface, for example, per unit length of the bubble grinding tube 5, for example, 10 In case of less than 3 stages, the bubbles in the swirling liquid are finely crushed by the swirling vane (3). Increasing resistance makes it impossible to obtain a proper flow of liquid, which makes it difficult to crush the bubbles properly, which makes the composition complicated and the inconvenience of having to assemble the swirl flow generating blade (3) and the bubble grinding protrusion (6) separately. There is a problem that the liquid is discharged to the outside by the gas injection.

In addition, since foreign matters contained in the liquid are loaded on the swirl flow generating blade 3 and the bubble grinding protrusion 6 to interfere with the flow of the liquid, smooth bubbles are not generated, and cleaning for removing the foreign matter is not easy. There is a problem.

In addition, when the bubble contained in the liquid collides with the bubble grinding projections 6, only a portion of the collision occurs, and the rest flows along the bubble grinding projections 6 due to the characteristics of the liquid. There has been a problem that can not be obtained.

In order to solve the conventional problems as described above, the present invention achieves cost reduction due to ease of assembly and a simple structure according to the simplification of the configuration, and can smoothly obtain fine bubbles, and by making a simple coupling to an existing facility, It is an object of the present invention to provide a nozzle for generating microbubbles unnecessary for the facility.

Preferably, at least one second through-hole is configured.
