DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Embodiment 1-1] The present invention relates to a nano bubble generating device, comprising: a casing (100) forming an inlet (110) and a discharge port (120) both sides of which pass through and forming a flow passage therein; And a bubble generator 200 having a plurality of bubble diffusions formed therein and formed as a cylindrical body.

The present invention generates nano-sized bubbles by using a gas-liquid mixture (water and air mixture). To achieve this, a gas-liquid mixture compressed at a high pressure passes through a bubble generator and air is separated into nano-sized particles.

[Example 1-2] The nano bubble generating device of the present invention In Example 1-1, a step 130 is formed on both sides of the casing, and a screw is formed on the outer peripheral surface of the step.

[Example 1-3] The nano bubble generating device of the present invention In Example 1-2, a casing cover 140 coupled to both sides of the casing and having a through hole 141 communicating with the flow path is included do.

For installation and replacement of parts inside the casing, the casing cover is screwed onto the step of the casing to enable the coupling and detachment. The casing cover prevents external departure of the parts.

[Embodiment 1-4] In the nano bubble generating device of the embodiment 1-3, a packing 150 is formed between the casing and the casing cover.

To prevent leakage of the gas-liquid mixture, a rubber-made packing is coupled between the casing and the casing cover. The packing exerts a sealing effect to prevent the outflow of the gas-liquid mixture.

[Example 1-5] Nano-bubble generator of the present invention In Example 1-1, the bubble generator forms a bubble diffuser in the inside thereof, and a stationary body 210 is formed in the outside.

The bubble generator supports the flow dispersion to be described later, and at the same time the bubble diffuser has to be accommodated. This is because high pressure is generated when bubbles are generated. Therefore, the fixture is preferably made of a stainless steel material having high corrosion resistance and durability. Or may be replaced with a material which exhibits the same purpose and effect as the substitution.

[Example 1-6] In the nano bubble generator of Example 1-6 of the present invention, the bubble diffuser includes a honeycomb-like structure.

The bubble diffuser physically breaks the minute bubbles and generates nano bubbles. In the case of the prior art, it is formed into a film-like structure in which most of the fine holes are formed. Therefore, fine holes cause flow resistance. Therefore, it is preferable that the bubbles have a shape capable of minimizing the flow resistance in the course of passing through the bubble diffuser. The bubble diffuser is formed in a honeycomb shape in which a plurality of thin plates are uniformly formed. Further, by uniformly forming the thin plate, the strength of the bubble diffuser can be maintained, and the size of the bubble can be uniformly generated.

 [Example 1-7] The nano bubble generator of Example 1-7 of the present invention includes a split piece 220 formed inside the bubble diffuser and formed of a projecting pin.

The nano bubbles passing through the bubble diffuser must be uniformly dispersed in water. A plurality of divided pieces are formed in the diagonal direction on the inner side of the bubble diffuser. The nano bubbles are uniformly dispersed by the plurality of divided pieces, and at the same time, the turbulent phenomenon is caused to obtain stable nano bubbles.

[Example 2-1] Nano-bubble generator of the present invention [0156] The nano bubble generator of Example 1-1 was manufactured in the same manner as in Example 1-1, except that a first flow path 160 extending from one side of the inlet port, a second flow path 160 extending from one side of the first flow path, And a third flow path 180 extending from one side of the second flow path.

The casing compresses air in the gas-liquid mixture and is continuously formed in a flow structure of the first flow path, the second flow path and the third flow path to increase the explosive force. Whereby the gas / liquid mixture can induce the production of nanobubbles by the first flow path, the second flow path and the third flow path.

[Example 2-2] In the nano bubble generator of Example 2-1 of the present invention, the first flow path had a first inclined surface 161 formed with an inclination and a first horizontal surface 162 extended from the first inclined surface, .

In order for the air in the gas-liquid mixture to be compressed, the gas-liquid mixture must flow smoothly. For this purpose, the flow area of the flow path can be widened to reduce the flow resistance. The first flow path forms a first inclined surface and a first horizontal surface. The first inclined surface extends from one end of the inlet, and the first horizontal surface extends from one end of the first inclined surface.

 [Example 2-3] In the nano bubble generator of Example 2-1 of the present invention, the second flow path had a second inclined surface 171 formed with an inclination and a second horizontal surface 172 extended from the second inclined surface, .

In order to generate nano bubbles, high-speed flow must be maintained inside the flow path. To this end, the second flow path must be reduced in width toward the rear. When the gas-liquid mixture rapidly passes through the second flow path, nano bubbles are generated by the fluid shear force. The second inclined surface extends from one end of the first horizontal surface, and the second horizontal surface extends from one end of the second inclined surface.

[Example 2-4] Invention Example 2-3 of the nano bubble generator of the present invention includes a spiral tube 174 having a plurality of spiral protrusions 173 formed on the inner circumferential surface of the second horizontal surface.

Inducing spiral rotation for effective bubbling and energy filling of the vapor-liquid mixture, which is obtained by the spiral projection formed inside the second horizontal plane.

 [Embodiment 2-5] In Embodiment 2-4 of the nano bubble generating device of the present invention, the spiral tube includes a case in which the interval between the projections becomes narrow toward the rear side.

[Example 2-6] In the nano bubble generating device of Example 2-4 of the present invention, the spiral tube includes those in which the intervals between the projections are formed uniformly or nonuniformly.

The spacing between the projections of the spiral tube may vary depending on the velocity of the vapor-liquid mixture flowing into the flow passage.

[Example 2-7] In the nano bubble generator of Example 2-1 of the present invention, the third flow path has a third inclined surface 181 formed upwardly inclined and a third inclined surface 181 extended from the third inclined surface 182).

In order to stabilize the nano bubbles in the water, a space for dispersing the flow of the nano bubbles should be formed. The third inclined surface extends from one end of the second horizontal surface, and the third horizontal surface extends from one end of the third inclined surface.

[Embodiment 2-8] In Embodiment 2-7 of the nano bubble generator of the present invention, the third horizontal surface includes a coupling groove 183 formed on one side.

There must be a flow path of nanobubbles between the third flow path and the flow dispersion. In order to form a flow passage, the position of the flow dispersion body must be fixed. To this end, the third horizontal surface forms a coupling groove to which one side of the flow dispersion body is coupled.

[Example 3-1] Invention Example 2-1 of the nano bubble generator of the present invention includes a accelerated derivative 300 disposed between the first flow path and the second flow path.

It should be possible to increase the rate of bubble generation. Therefore, the flow rate of the gas-liquid mixture in the flow path must be increased and discharged quickly. To this end, an accelerated derivative is formed between the first flow path and the second flow path. A gas-liquid mixture that passes through an accelerating derivative increases the flow rate and extraction energy.

 [Example 3-2] In the nano bubble generator of Example 3-1 of the present invention, the above-mentioned accelerated derivatives include those in which both sides are formed in a streamlined shape.

The flow resistance of the gas-liquid mixture should be minimized. For this purpose, the accelerating derivatives are formed in streamlined form. Since the gas-liquid mixture flows in a streamlined manner, the gas-liquid mixture flowing into the channel is not subjected to a great resistance.

 [Example 3-3] In the nano bubble generator of Example 3-2 of the present invention, the accelerated derivatives include a plurality of guides 310 formed at regular intervals on the outer circumference.

A plurality of guides are formed to induce a stable flow of the gas-liquid mixture and prevent flow resistance by turbulence. The flow rate in the accelerating derivative is increased. Therefore, turbulence occurs due to the increase of the speed, which causes the problem of bubble breaking at an early stage.

[Example 4-1] Nano bubble generator of the present invention A flow dispersion body 400 according to the practical example 2-1, which is disposed in the third flow path and has a plurality of dispersion plates 410 formed therein, .

The bubbles generated through the second flow path must be finely divided to have a nanoscale size. For this purpose, a flow dispersion is formed behind the accelerating derivatives. The flow dispersion body is supported by a casing cover. The bubble particles are pulverized and uniformly dispersed through the dispersion plate. The dispersed nanobubbles stabilize in water.

[Example 4-2] In the nano bubble generator of Example 4-1 of the present invention, the flow dispersion body was formed in a ring shape, and a coupling protrusion 420 was protruded on one side.

The flow dispersion enhances the strength of the dispersion plate. This is because high pressure is generated when bubbles are generated. Therefore, the flow dispersion body is formed in a ring shape so as to surround the dispersion plate. The engaging projection is formed to fix the flow dispersion body in the third flow path. The engaging projection is engaged with the engaging groove formed on the third horizontal surface of the third flow path.

[Example 4-3] Invention Example 4-1 of the nano bubble generating device of the present invention: Fixture 430 formed on the other side of the flow dispersion material; And a dispersion head 440 coupled to one side of the fixture and moving laterally.

The explosive power of the gas-liquid mixture should be high. To this end, a fixture is formed in the middle portion of the flow dispersion body, and a dispersion head is formed at the tip of the fixture. The nano bubbles first collide with the dispersing head before colliding with the dispersing plate to improve the explosive force.

[Example 4-4] In Example 4-3 of the nano bubble generator of the present invention, one side of the dispersion head includes a cone-shaped one.

It is an ideal shape with a small hydrodynamic resistance. The dispersion head is tapered toward the tip and the tip is sharpened. This shape minimizes the flow loss of nano bubbles.

[Example 4-5] Invention Example 4-4 of the nano bubble generator of the present invention is a transfer bubble generating device in which the transfer shaft 450, which is connected to the other side of the dispersion head and forms a male screw on the outer circumferential surface, (470) formed on one side of the feed shaft, a rotary member (490) coupled to the spline, and rotated by a drive motor (480) .

The dispersion head can be coupled back and forth to the fixture. To this end, the rotary member is rotated by the operation of the drive motor, and the delivery shaft is also rotated while the spline is rotated together with the rotation of the rotary member. The rotating conveying shaft is guided by the fixing body to reciprocate. Therefore, the pressure is formed at the time of advancing the dispersion head, and the effect of increasing the pressure increase efficiency can be obtained. Increasing the pressure increase efficiency increases the discharge amount of nano bubbles.

[Example 5-1] Nano-bubble generating device of the present invention [0216] The nano bubble generator of Example 1-1 was provided with a pump 500 connected to one side of the casing for conveying a gas-liquid mixture mixed with a gas and a liquid, And a chamber 600 connected to the other side and receiving water therein.

A pump is used to mix the gas-liquid mixed vapor-liquid mixture to produce nanobubbles. The liquid and gas introduced at the front end of the pump are mixed to form a gas-liquid mixture. The gas-liquid mixture passes through the nano bubble generator to be nano-saturated and is discharged into the water contained in the chamber.
