The bubble crushing plate 3300 has a plurality of through-holes 3320, so that the water containing the air bubbles discharged from the bubble generating tube 3200 is separated from the plurality of through-holes 3320 and then mixed. Thus, the air bubbles contained in the water are more finely pulverized.

A discharge passage 3520 is formed in the lower housing 3500 to discharge water containing the air bubbles pulverized from the bubble crushing plate 3300.

In addition, the water containing the crushed air bubbles discharged to the discharge passage 3520 of the lower housing 3500 is injected into the bubble grinding nozzle 3700 through the connecting pipe 3600, the bubble grinding nozzle 3700 is water The bubbles contained in the pulverizer are further crushed to discharge water containing the rich fine bubbles.

In addition, a fitting hole 3310 for passing the support bar 3400 may be formed in the central region of the plate-shaped bubble crushing plate 3300.

Accordingly, the support rod 3400 is inserted into the fitting hole 3310 of the bubble crushing plate 3300, and the bubble crushing plate 3300 fitted to the support rod 3400 is caught by the catching jaw 3410, and thus the lower portion of the catching jaw 3410. The support rod 3400 does not go down, and one end of the support rod 3400 is fixed to the fixing groove 3510 of the lower housing 3500.

In addition, the microbubble generating device of the embodiment of the present invention in order to maintain the balance of the bubble crushing plate 3300 inserted in the support rod 3400, the fitting fixing hole (3451) that can be fixed to the support rod 3400 and the fitting fixed The balance plate 3450 may be further configured to include a plurality of water flow passages 3451 formed around the hole 3451.

5 is a bottom perspective view of a bubble grinding plate applied according to the present invention, and FIG. 6 is a cross-sectional view of a bubble grinding plate applied according to the present invention.

5 and 6, the bubble crushing plate 3300 has a plate shape (including a disc shape), and a fitting hole 3310 is formed in the center area, and a plurality of through holes formed in the bubble crushing plate 3300 are formed. The hole 3320 is formed in an area around the fitting hole 3310.

Water containing the air bubbles discharged from the bubble generating tube 3200 to the bubble crushing plate 3300 passes through the plurality of through holes 3320 of the bubble crushing plate 3300 and the housing (upper housing and lower housing are combined). State) to the bottom.

Here, at least some of the plurality of through holes 3320 of the bubble crushing plate 3300 may be formed of an inflow area 3321 and an outflow area 3322 of water, and an inner diameter of the inflow area 3321 may be an outflow area 3322. It is designed smaller than the inner diameter of.

That is, the water containing air bubbles introduced into the plurality of through holes 3320 of the bubble crushing plate 3300 passes through the inflow area 3321 with a small inner diameter, and then flows out into the outflow area 3322 with a large inner diameter. By mixing, the fine air bubbles are broken down to finer size.

In this case, the inner diameters D1, D2, and D3 of the outlet regions 3322 of the plurality of through holes 3320 of the bubble crushing plate 3300 are gradually increased in the radial direction from the fitting hole 3310 as shown in FIG. 5. Can be designed.

When the water containing the introduced air bubbles flows into the inflow area 3321 of the plurality of through holes 3320 of the bubble breaking plate 3300, the inner diameter of the inflow area 3321 of the plurality of through holes 3320 is small, The water containing the introduced air bubbles may not quickly exit the plurality of through holes 3320 and may remain above the bubble crushing plate 3300.

In order to solve this problem, the flow rate through the through hole increases toward the edge of the bubble grinding plate 3300 far from the fitting hole 3310 to reduce water staying on the upper side of the bubble grinding plate 3300 as much as possible and The inner diameters D1, D2, and D3 of the outlet regions 3322 of the plurality of through holes 3320 may be gradually increased in the fitting holes 3310 so that air bubbles may be crushed in the through holes 3320. will be.

At this time, the area of the bubble crushing plate 3300 increases as the radial direction increases in the fitting hole 3310. For this reason, the area of the bubble crushing plate 3300 farther from the edge of the bubble crushing plate 3300 farther from the fitting hole 3310 is increased. The inner diameter of the outlet area 3322 of the through hole 3320 may not be large in the area of the bubble grinding plate 3300 adjacent to the fitting hole 3310 because the area of the adjacent bubble grinding plate 3300 is small.

Therefore, the inner diameters D1, D2, and D3 of the outflow areas 3322 of the plurality of through holes 3320 are formed by the coupling relationship between the bubble crushing plate 3300, the fitting hole 3310, and the plurality of through holes 3320. In the fitting hole 3310 is to be designed to increase gradually in the radial direction.

7 is a perspective view of a bubble generating tube according to the present invention, Figure 8 is a schematic cross-sectional view of the bubble generating tube according to the present invention.

7 and 8, in the bubble generating tube according to the present invention, the first flow path 11, the boosting structure 200, and the second flow path 111 are sequentially arranged to flow water in that order. A water supply part configured to be connected to the water supply part, a drain part connected to the second flow path 111 of the water supply part to discharge water supplied from the water supply part, and an air supply formed at a side of the drain part to supply air to the drain part; Pipe 300. At this time, the inner diameter (D2) of the second flow path 111 is smaller than the inner diameter (D3) of the drainage portion or the inner diameter (D1) of the first flow path (11), the first flow path 11 and the first The boosting structure 200 interposed between the two flow passages 111 and passing the water from the first flow passage 11 to the second flow passage 111 is a portion adjacent to the first flow passage 11. The inner diameter gradually decreases from (a) to the portion (b) adjacent to the second flow path 111. A mountain and a valley are formed on the inner inclined surface thereof.

That is, the second flow path 111 is located at the center of the boosting structure 200.

The water supply part of the present invention is composed of a first flow passage 11, the pressure-increasing structure 200 and the second flow passage 111, Figure 8 is a first horizontal pipe 100 and the second horizontal pipe (10) 2 The above configuration is shown by connecting two pipes. Here, the first horizontal pipe 100 and the second horizontal pipe 10 are screwed.

The constant supplied through the first flow path 11 of the water supply part is increased in pressure in the booster structure 200 and flows to the second flow path 111, and the water pressure of the water flowing into the second flow path 111 is the first flow path. It becomes larger than the water pressure of the constant supplied to the furnace 11.

Here, the constant is the water pressure of the water flowing in the second flow path 111 while being bumped out of the mountain and valley formed in the pressure-increasing structure 200 to the second flow path 111 is greater than the water pressure of the constant.

In addition, a spiral screw (not shown) may be protruded from the inner circumferential surface of the second flow passage 111 to guide the rotation of the flowing water. In this case, the water flowing through the second flow passage 111 may be rotated by the screw. By forming a current it can be strongly discharged to the third flow path 121 of the drain portion (120).

At this time, the second flow path 111 may be defined as extending from the pressure-increasing structure 200 to the drain.

The booster structure may be formed integrally with the first horizontal pipe 100 or may be manufactured separately from the first horizontal pipe 100.

In the following description, it is assumed that the pressure-increasing structure is composed of a component manufactured separately from the horizontal pipe 100.

The inner diameter D1 of the first flow passage 11 is designed to be larger than the inner diameter D2 of the second flow passage 111 of the water supply unit 110.

The constant supplied through the first flow path 11 flows through the second flow path 111 of the water supply unit 110 at the center of the pressure-increasing structure 200 by increasing the pressure in the pressure-increasing structure 200. The water pressure of the water flowing into the second flow passage 111 of 110 becomes greater than the water pressure of the constant.

That is, the water pressure of the water flowing into the second flow passage 111 of the water supply unit 110 while the constant hits the booster structure 200 quickly exits the second flow passage 111 is greater than the water pressure of the constant.

Since the inner diameter D3 of the third flow path 121 of the drainage part 120 is designed to be larger than the inner diameter D2 of the second flow path 111 of the water supply part 110, the water supply part having a smaller inner diameter is provided. Water flowing into the second flow passage 111 of 110 suddenly exits to the third flow passage 121 having a large inner diameter and negative pressure is generated.

Water exiting from the second flow passage 111 of the water supply portion 110 to the third flow passage 121 of the drain portion 120 by the negative pressure is disposed perpendicular to the horizontal axis of the first horizontal pipe 100. It sucks in the air supplied from the air supply pipe (300).

That is, air is absorbed into the water flowing in the third flow passage 121 of the drainage portion 120 to form water containing bubbles.

Therefore, the water discharged from the third flow passage 121 of the drainage portion 120 becomes bubbled water containing air (air bubble form).

Accordingly, the bubble generating tube according to the present invention distributes the constant of which the water pressure is increased through the pressure-increasing structure to the second flow passage of the water supply portion having the small inner diameter, and the third portion of the drain having the relatively large inner diameter of the water flowing in the second flow passage. By discharging to the distribution channel to generate a negative pressure in the third flow path of the drain, the air supplied from the air supply pipe is absorbed by the water discharged from the second flow path of the water supply to the third flow path of the drain through the negative pressure In this case, the water containing the bubbles may be discharged from the third flow passage of the drain.

At this time, in view of the inventor's experience, it is preferable that each of the hills and valleys of the boost structure is formed with at least three or more odd numbers.

That is, as shown in FIG. 9A, the peaks 205a1, 205a2, and 205a3 are positioned on 360 ° of the one surface 205 of the booster structure with the second flow path 111 of the water supply unit 110 as the central axis. When each of the valleys 205b1, 205b2, and 205b3 is formed in three, the angles α1, α2, and α3 between the mountains are 120 °, the valleys are formed between the mountains, and the booster structure separately manufactured is illustrated in FIG. 3B. It becomes a structure like Here, the boosting structure 200 of FIG. 9B functions as the second flow path 111 beyond the range from the portion a adjacent to the first flow passage to the portion b adjacent to the second flow passage 111. It shows the case that the part is made to include part.

That is, by controlling the opening and closing degree of the plurality of air holes of the opening and closing means by turning the screw protruding to the outside of the air control valve 520, to control the amount of air supplied to the air supply pipe 300 in communication with the extension pipe 510 will be.

15 is an exploded perspective view of a first embodiment of the bubble grinding nozzle of the present invention, and FIG. 16 is an assembled cross-sectional view of FIG. 15.

Bubble crushing nozzle of the present invention is made of a pipe shape including an inlet in which the water containing the bubble is introduced, and a flow passage communicating with the inlet and having an inner diameter larger than the inner diameter of the inlet, a plurality of passages through the water The first plate having a first flow path of the second plate and the second plate formed with a plurality of second flow paths are formed sequentially at a predetermined interval so that the water entering the inlet through the first plate and a predetermined space through the second plate It is configured to pass through. 15 and 16 illustrate a first embodiment implementing the above configuration.

15 and 16, the bubble grinding nozzle according to the first embodiment of the present invention is in communication with the inlet 1101, and the inlet 1101 through which the water containing the fine air bubbles made from the outside is in communication with the A first nozzle pipe 1100 including a flow path 1102 having an inner diameter greater than that of the inlet 1101; A first plate (1200) opposed to the inlet (1101) and inserted into the flow path (1102) and having a plurality of first flow paths (1210) through which the water passes; A first ring chamber 1300 contacted with the first plate 1200 and inserted into the flow path 1102 and filled with water passing through the plurality of first flow paths 1210 of the first plate 1200. ; A second plate contacting the first ring chamber 1300 and inserted into the flow path 1102, and having a plurality of second flow paths 1610 passing through the water filled in the first ring chamber 1300. (1600); And a second nozzle pipe 1800 contacted with the second plate 1600 and inserted into the flow path 1102, and coupled to an end of the flow path 1102 of the first nozzle pipe 1100. .

In addition, in the first embodiment, when the end of the flow path 1102 of the first nozzle pipe 1100 is defined as the first outlet 1103, the second nozzle pipe 1800 is coupled to the first outlet 1103. do.

For reference, in the present invention, a predetermined interval between the first plate and the third plate may be implemented by various configurations, but in the first embodiment, the above-described constant interval is formed by the first ring chamber. will be.

In addition, although the two nozzle pipes are not necessarily required in the practice of the present invention, the first embodiment exemplifies a case in which the two nozzle pipes, the first nozzle pipe 1100 and the second nozzle pipe 1800, are used. It was.

By the above configuration, the inlet 1101 of the first nozzle pipe 1100 is introduced into the water containing the fine air bubbles generated by any fine bubble generator, the water is located on the flow path 1102 More finely pulverized while passing through the first plate 1200, the first ring chamber 1300, and the second plate 1600 is discharged to the second nozzle pipe 1800 coupled with the first outlet 1103.

In the first embodiment, the inner diameter of the flow path 1102 of the first nozzle pipe 1100 is larger than the inner diameter of the inlet port 1101. The first plate 1200 and the first ring chamber located on the flow path 1102. This is to prevent the 1300 and the second plate 1600 from being separated into the inlet 1101. Therefore, as long as it has an appropriate structure, it is also possible to design the inner diameter of the flow path 1102 of the 1st nozzle pipe 1100, and the inner diameter of the inflow port 1101, for example.

In the first embodiment, the second nozzle pipe 1800 is inserted into the flow path 1102 to be coupled to the first outlet 1103 of the first nozzle pipe 1100 while being in contact with the second plate 1600. The plate 1200, the first ring chamber 1300, and the second plate 1600 serve to closely contact the inlet 1101.

That is, as shown in FIG. 16, the end of the second nozzle pipe 1800 is coupled with the first outlet 1103 of the first nozzle pipe 1100, so that the end of the second nozzle pipe 1800 is second. While contacting the plate 1600, the first plate 1200, the first ring chamber 1300, and the second plate 1600 are in close contact with each other, and the first plate 1200 is in close contact with the inlet 1101. Thus, the water passing through the inlet 1101 passes through the first flow path 1210 of the first plate 1200, the first ring chamber 1300, and the second flow path 1610 of the second plate 1600. do.

Here, the first and

second plates

1200 and 1600 are plate-shaped (preferably disc-shaped). The number of the second flow paths 1610 of the second plate 1600 may be larger than the number of the first flow paths 1210 of the first plate 1200. The mixing of water may be promoted by varying the water passage flow rates of the first flow path 1210 and the second flow path 1610 of the second plate 1600.

In addition, by increasing the number of the second flow path 1610 of the second plate 1600 that can perform the water mixing and grinding action alone, it is also possible to increase the water mixing and grinding action.

Here, the inner diameter of the second flow path 1610 of the second plate 1600 may be designed to be smaller than the inner diameter of the first flow path 1210 of the first plate 1200.

In addition, in the first embodiment, the first ring chamber 1300 is interposed between the first and second plates 1600 in a ring shape, so that the inside of the ring functions as a chamber in which water is filled. Thus, the water passing through the first flow path 1210 of the first plate 1200 is filled in the first ring chamber 1300 and mixed to separate the fine air bubbles contained in the water to a finer size. Then, the water filled in the first ring chamber 1300 exits to the second flow path 1610 of the second plate 1600.

Meanwhile, each of the plurality of second flow paths 1610 of the second plate 1600 includes an inflow area 1611 and an outflow area 1612 of water, and an inner diameter of the inflow area 1611 is an outflow area 1612. It is designed smaller than the inner diameter of. Thus, as water passes through the inflow region having the small inner diameter of the second flow path 1610 and exits to the outflow region having the relatively large inner diameter, the water mixes with each other and strikes the side wall of the outlet region 1612. The air bubbles are more finely crushed through the mixing process in which the fine air bubbles are mixed with water and the collision process against the side walls.

Here, the outflow region 1612 having a large inner diameter of the second plate 1600 is formed by processing into a concave cylindrical (preferably cylindrical) groove, and the inflow region 1611 having a small inner diameter has an outflow region 1612. It can be implemented as a hole having a smaller inner diameter than).

The inside angle of the outlet area 1612 of the second flow path 1610 of the second plate 1600 is preferably at right angles, from the inlet area 1611 having a small inner diameter to the outlet area 1612 having a large inner diameter. When water is discharged, the mixing action of the water can be increased to improve the crushing effect of the bubbles.

By the above structure, the water filled in the first ring chamber 1300 first flows into the inlet area 1611 having a smaller inner diameter of each of the second flow passages 1610, and then has a relatively large inner diameter outlet region 1612. The fine air bubbles contained in the water are pulverized to a finer size through the outflow process to).

On the other hand, the length of the water outlet area 1612 of the second flow path 1610 in the second plate 1600 is preferably designed to be longer than the length of the water inlet area 1611. The inflow area 1611 of the second flow path 1610 is simply an area through which water passes, whereas the outflow area 1612 substantially mixes water, thereby pulverizing fine air bubbles contained in the water. This is because it is an area.

By the bubble grinding nozzle according to the first embodiment of the present invention described above, the water containing the introduced fine air bubbles is the first flow path of the first plate, the first ring chamber, the second flow path of the second plate By passing through the mixing and grinding process, it is possible to produce abundantly finer bubbles.

Next, a second embodiment of the bubble grinding nozzle will be described.

17 is an exploded perspective view of a bubble grinding nozzle according to a second embodiment of the present invention, and FIG. 18 is an assembled cross-sectional view of FIG. 17.

The bubble grinding nozzle according to the second embodiment of the present invention may include a third plate 1400 and a second ring chamber between the first ring chamber 1300 and the second plate 1600 of the bubble grinding nozzle of the first embodiment. 1500) are sequentially configured to further intervene.

Here, one surface of the third plate 1400 contacts the first ring chamber 1300, and one surface of the second ring chamber 1500 contacts the other surface of the third plate 1400, and the second ring chamber 1500. The second plate 1600 is in contact with the other surface.

Therefore, the second ring chamber 1500 is interposed between the third plate 1400 and the second plate 1600 to form a chamber inside the ring structure of the second ring chamber 1500.

The third plate 1400 includes a plurality of third flow passages 1410 through which water passes, and the third flow passage 1410 is implemented as a hole penetrated from one surface of the third plate 1400 to the other surface.

Furthermore, in the second embodiment, when the end of the second nozzle pipe 1800 is coupled with the first outlet 1103 of the first nozzle pipe 1100, the first plate 1200, the first ring chamber 1300, The third plate 1400, the second ring chamber 1500, and the second plate 1600 may be in close contact with the inlet 1101 so that the third plate 1600 and the second nozzle pipe 1800 may be more closely adhered to each other. The contact ring 1700 may be further interposed between the ends.

The first and third plates 1400, the first and second ring chambers 1500, and the second plate 1600 are configured to adjust the flow rate and the filling amount of the chamber to maximize the mixing of water to more fine air bubbles. By pulverization, water with increased bubble generation can be discharged.

In addition, in the present invention, the number of the third flow paths 1410 of the third plate 1400 is equal to or less than the number of the first flow paths 1210 of the first plate 1200, and the first plate 1200. The number of first flow paths 1210 of the second plate 1600 may be designed to be less than the number of second flow paths 1610 of the. That is, by differently designating the number of distribution channels of the first to

third plates

1200, 1600 and 1400, the water mixture passing through the distribution channels of the first to

third plates

1200, 1600 and 1400 may be further increased. It is.

Here, designing the number of the third flow paths 1410 of the third plate 1400 to be equal to or less than the number of the first flow paths 1210 of the first plate 1200 may include the first plate 1200. When the water discharged into the first flow passage 1210 of the (3) passes through the third flow passage 1410 of the third plate 1400, the water pressure is increased to activate the mixing of the bubbles to improve the crushing effect of the bubbles To do so.

In addition, the number of second flow paths 1610 of the second plate 1600 may be determined by the number of first flow paths 1210 of the first plate 1200 and the third flow paths 1410 of the third plate 1400. More than the number is to increase the mixing action of the water in the second flow path 1610 of the second plate 1600 and the grinding action of the fine air bubbles contained in the water.

Meanwhile, in the first embodiment, the first nozzle pipe 1100, the first plate 1200, the first ring chamber 1300, the second plate 1600, and the second nozzle pipe 1800 are illustrated as separate configurations. However, some or all of these configurations may be formed in one configuration. The same applies to the second embodiment. For example, the first plate 1200 and the first ring chamber 1300 may be integrally formed.
