The pump pumps the water from the tap water source for water purification and provides it to the fine bubble generator 100 through the conduit 18.

The microbubble generator 100 is located in the conduit 18 (see FIG. 2), generates microbubble-containing water containing ionized air, and then flows out to the water supply source.

2 is a schematic perspective view of a micro bubble generator 100 (hereinafter referred to as 'MBG') for generating micro bubbles according to an embodiment.

Referring to FIG. 2, the MBG 100 may be installed in the conduit 18, and may include a gas injection tube 400, a blade unit 120, a chamber 130, and a driver 140.

The gas injection tube 400 is a circular tube for injecting gas (eg, ionized air) to the chamber 130 side. There may be a pump not shown between the gas injection tube 400 and the air ionizer 50, by which the air ionized by the air ionizer 50 may be injected into the gas injection tube 400. have.

In the illustrated embodiment, the gas injection pipe 400 is in the shape of a hollow circular pipe and is installed to penetrate the chamber 130 and the connection portion 121. A bearing 111 is interposed between the gas injection pipe 400 and the connection part 121, so that the rotation of the connection part 12 does not affect the gas injection pipe 400.

In this embodiment, the central axis of the gas injection pipe 400 and the protrusion 131 of the chamber are aligned with each other.

The gas injection pipe 400 has a shape of a pipe through which gas flows, and the gas flowing in the gas injection pipe 400 is pressurized to move in the direction of the chamber 130.

The blade unit 120 is coupled to surround the outside of the gas injection pipe 400 and is a member that rotates independently of the gas injection pipe 400. The blade part 120 may include a connection part 121 and a plurality of blades 122. The connection part 121 is a cylindrical member surrounding the outside of the gas injection pipe 400, and a plurality of blades 122 are connected to the connection part 122, which is a cylindrical member, at a predetermined interval along the side of the connection part 122 in a radial direction. Attached.

Each blade 122 extends in the radial direction at the connecting portion 121 and the blade 129 is suspended, so that the blade 122 rotates when the blade 129 is rotated by the flow rate.

One end of the blade 122 is attached to the connecting portion 121 and extends substantially horizontally in a radially outward direction therefrom, and is bent downward so that the other end thereof faces vertically downward.

Specifically, the blade 122 is a horizontal extension portion extending horizontally in the radial direction from the connecting portion 121 surrounding the gas injection pipe 400, and bent downward at the end of the extension portion is directed vertically downward It includes a vertical downward portion, wherein the horizontal extension portion is positioned in parallel with a predetermined distance spaced apart from the upper surface of the chamber 130 to be described later, the vertical downward portion is positioned parallel to the side surface of the chamber 130.

The chamber 130 is a member rotatably coupled to the lower end of the gas injection tube 400, and may include a protrusion 131, a body 132, and a filter 133.

The main body 132 of the chamber is hollow, and is a cylindrical member composed of an upper surface, a side surface, and a lower surface. The diameter of the chamber 130 is slightly smaller than the diameter of the blade portion 120. That is, when the chamber 130 is coupled to the rotational axis P1, a portion of the blade 122 facing downward is spaced apart from the side surface of the chamber 130 by a predetermined distance.

At the center of the upper surface of the chamber 130, the protrusion 131 is formed to protrude from the upper surface. The protrusion 131 has a vertical through hole formed therein, and the gas injection pipe 400 penetrates the protrusion 131. A bearing is interposed between the gas injection pipe 400 and the protrusion 131, so that the chamber 130 rotates around the gas injection pipe 400.

A plurality of openings are formed in the side surface of the chamber 130 at predetermined intervals, and a filter 133 is attached to each opening. In a preferred embodiment, the filter 133 may be a porous sintered filter, so that when gas passes through one side of the filter 133, it becomes a microbubble and may be discharged from the other side of the filter 133. The filter 133 may be made of a material (eg, stainless steel or resin) including a micro path through which gas can pass.

The driving unit 140 is disposed below the chamber 130. The driving unit 140 includes a motor 142 and a drive shaft 141. One end of the drive shaft 141 is connected to the rotation shaft of the motor 142 and the other end is coupled to the center of the lower surface of the chamber 130. Thus, the chamber 130 is rotated by the motor 142.

Figure 3 is a cross-sectional view of the connecting portion according to an embodiment of the present invention.

As shown in FIG. 3, a bearing 111 is interposed between the gas injection pipe 400 and the connection part 121 such that the rotation of the connection part 12 does not affect the gas injection pipe 400.

4 is a cross-sectional view of the chamber 130 according to one embodiment. 4, the protrusion 131 of the chamber 130 is coupled to the lower end of the gas injection pipe 400 through a bearing 134. Since the chamber 130 is rotatably coupled to the gas injection tube 400, the chamber 130 may rotate by receiving a driving force from the driving shaft 141 about the gas injection tube 400.

Meanwhile, gas is discharged from the lower end of the gas injection tube 400 to fill the inside of the body 132 of the chamber 130. When the pressure of the gas rises above a certain level, the gas is discharged to the outside (water in the river) through the filter 133. At this time, the gas passing through the filter 133 is discharged into the water in the form of micro-sized bubbles. Furthermore, since the chamber 130 is rotated in the direction opposite to the rotation direction of the blade, fine bubbles can be easily generated.

5 is a schematic side view of a state in which the above-described MBG 100 is disposed in the conduit 18 according to an embodiment.

Referring to FIG. 5, it can be seen that the gas injection pipe 400 penetrates the connection part 121 and is connected to the chamber 130. The blade portion 120 is coupled to the connection portion 121, and a chamber 130 is rotatably coupled to the gas injection pipe 400 below. The chamber 130 is driven by the motor 142 and may rotate independently of the rotational direction of the blade 122 (preferably in the opposite direction). In FIG. 5, for convenience of description, the blade 139 in FIG. 2 is omitted. As shown in FIG. 5, each blade 122 is positioned close to the filter 133 so that the bubbles exiting through the filter 133 may be generated by the blade 122 into further finer bubbles. will be.

FIG. 6 shows an enlarged view of a portion A in FIG. 5.

In the preferred embodiment, while the chamber 130 is rotated by the driving unit 140, the gas in the chamber 130 is rotated under pressure according to the continuous gas supply from the gas injection pipe 400, and thus the filter 133. ) Is discharged into the water in the form of fine bubbles (MB). At this time, since the chamber 130 is being rotated, the fine bubbles are cut by the flow of river water around the moment when discharged through the filter 133 can be broken down to a smaller size.

Since the side of the main body 132 of the chamber 130 and the vertically downward portion of the blade 122 are adjacent to each other, the fine bubbles collide with the blade 122 immediately after being discharged into water, Can be cut back. At this time, preferably, the larger the relative rotational speed of the chamber 130 and the blade 122 will be finely cut fine bubbles. That is, according to one embodiment, the relative rotation speed can be increased by rotating the chamber 130 in the opposite direction to the rotation direction of the blade 122.

The wing 129 is rotated by the flow of water flowing in the conduit 18, thereby rotating the blade 122. Referring to Fig. 2, the shape of the blade 129 is configured in a scoop shape (with recesses) such that the blade 122 is rotated in a specific direction (counterclockwise (ccw)). In this case, although not shown, the power supply (not shown) through the power supply line 450 supplies power to the motor 142 so that the chamber 130 rotates clockwise (cw). That is, in FIG. 1, a power source (not shown) that provides power to the microbubble generator 100 through the power supply line 450 may have a rotation direction of the chamber 130 opposite to a rotation direction of the blade 122. The motor 142 is controlled.
