Hereinafter, a preferred embodiment of the water purification aeration system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view showing a preferred embodiment of the water purification aeration system according to the present invention, Figure 2 is a plan view showing a schematic connection structure of the water pipe and the air pipe constituting an embodiment of the present invention, Figure 3 is an embodiment of the present invention 4 is a cross-sectional view illustrating a structure of an air supply unit, and FIG. 4 is a cross-sectional view illustrating a structure of an air supply unit according to another embodiment of the present invention.

As shown in these figures, the water purification aeration system according to an embodiment of the present invention is provided with a water discharge device for discharging the water in the water to various locations in the water.

As the water discharging device, in this embodiment, the pump unit 1 for drawing up the water in the water and the moving path of the water to discharge the water introduced into the pump unit 1 to various positions in the water The first water pipe 21 and the second water pipe 22 are provided.

The pump unit 1 introduces a water inlet duct 12 having a water inlet 12a and water into the water inlet duct 12 to the first water pipe 21 and the second water pipe 22. It consists of a pump 11 for flowing in turn. Here, each of the second water pipes 22 is provided with a water discharge port 22a.

A first hydraulic pressure balance tank 31 is disposed between the first and second water pipes 21 and 22. The first water pressure balance tank 31 is connected to the first water pipe 21 and the second water pipes 22 to temporarily store water introduced into the water through the first water pipe 21.

As described above, a large amount of water is stored in the first hydraulic pressure balance tank 31 having a large storage space for a predetermined time, and the second water pipes having a narrow diameter at about the same time after the predetermined time has elapsed. By discharging to 22, it is possible to prevent the phenomenon that water is discharged through only one of the second water pipes 22.

As a result, water is uniformly distributed to each of the second water pipes 22 having a small inner diameter, so that the speed of the water is increased, and the air discharge ports 62a to be described below disposed adjacent to each of the water discharge ports 22a. The speed of the air discharged to the air becomes faster. When the speed of the discharged air is increased, the pressure at each air discharge port 62a is lowered, and the air can be smoothly discharged through each air discharge port 62a.

Similarly, each of the second water pipes 22 is provided with a second hydraulic pressure balance tank 41 that can temporarily store water discharged from the first hydraulic pressure balance tank 31 before being supplied to the water discharge port 22a. The second hydraulic pressure balance tank 41 has the same function as the first hydraulic pressure balance tank 31.

On the other hand, the water purification aeration system according to an embodiment of the present invention is provided with an air discharge device for allowing the air in the air to be discharged to various locations in the water together with the water.

As such an air discharge device, in this embodiment, the air suction unit 5, the first air engine 61, and the second air engine 62 are provided.

The air suction unit 5 serves to introduce air in the air into the first air engine 61, and includes an air inlet duct 51 and a fan 52 disposed in the air and having an air inlet.

The air inlet duct 51 is formed in a conical shape that gradually decreases the inner diameter, so that the pressure of the portion connected to the first air pipe 61 side is reduced to smoothly flow air into the first air pipe 61.

In addition, the air inlet duct 51 has a rotating member 53 extending downward from the position corresponding to the center of gravity. The rotating member 53 is rotatably coupled to the first air engine 61 so that the air inlet duct 51 can be rotated according to the wind direction.

Of course, in this embodiment, the air pressure tank 7 is disposed between the air inlet duct 51 and the first air pipe 61, so that the rotating member 53 via the air pressure tank (7). By rotatably coupled to the first air pipe 61, it is apparent that the present invention can also be applied to a structure that is not provided with an air pressure tank (7).

Here, the air pressure tank (7) is for temporarily storing the air introduced from the air inlet duct 51, disturbance that prevents air from being discharged to the air outlet (62a), that is, the second air engine It is possible to continuously supply air even in the case of flow of the 62 elements.

As such, a large amount of air is stored in the air pressure tank 7, which may result in backflow of the stored air to the air inlet duct 51. However, the check damper 54 is provided in the present invention. Such reverse spillage is prevented.

In addition, the first air pipe 61 is provided with an air amount measuring device for measuring the amount of air flowing from the air pressure tank (7). Such an air volume measuring instrument is provided to remotely monitor the air amount introduced into the first air engine 61 and to measure the air amount introduced into the first air engine 61.

The fan 52 is rotatably installed at the air inlet side of the air inlet duct 51 to allow air in the atmosphere to flow into the air inlet duct 51. Thus, the principle and function that allows the fan 52 to enter the air inlet duct 51 is as follows.

When the pressure at the air discharge port 62a is lowered by the speed of water discharged to the water discharge port 22a, the air is discharged from the air inlet duct 51 by the pressure difference between the air inlet port 51a and the air discharge port 62a. Air in the water is forced into the air inlet duct 51. The fan 52 rotates due to the inflow of air, and the rotation of the fan 52 sucks the surrounding air into the air inlet duct 51.

Then, after the fan 52 is rotated, the rotation can be maintained by the rotational inertia, so that air can be continuously introduced into the air inlet duct 51.

On the other hand, the first pneumatic balance tank 31 is provided with a first pneumatic balance tank 32 disposed between the first air pipe 61 and each of the second air pipe (62). Each of the second air pipes 62 is provided with a second pneumatic balance tank 42 capable of temporarily storing the air discharged from the first pneumatic balance tank 32 before being supplied to the air discharge port 62a. The second pneumatic balance tank 42 is provided inside the second hydraulic balance tank 41.

The first pneumatic balance tank 32 stores a large amount of air in a large storage space for a predetermined time, and after the predetermined time has elapsed, the first pneumatic balance tank 32 has a diameter in each of the second air pipes 62 having a narrow diameter. By discharging, it is possible to prevent the phenomenon that the air is discharged only through either of the second air pipes 62. The second pneumatic balance tank 42 also has a similar function.

Here, as each pneumatic balance tank is provided in each hydraulic balance tank, each second air pipe 62 is provided inside each second water pipe 22. As such, by providing the second air pipe 62 inside the second water pipe 22, it is possible to prevent the second air pipes 62 from rising to the surface due to buoyancy.

Now, the air supply unit 8 according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4.

As shown in Figure 3, the air supply unit 8 according to an embodiment of the present invention accommodates the water discharge port 22a and the air discharge port 62a. The air supply unit 8 is provided with a through hole 80 having the same inner diameter for a predetermined section. The through hole 80 makes the turbulent flow of water and air discharged from the water discharge port 22a and the air discharge port 62a into a laminar flow state. By doing so, it is possible to effectively purify the contaminated water by reducing the amount of water and air discharged.

Here, the length of the through hole 80 is preferably formed to be longer than the length of the tapered portion (22b) provided in the second water pipe (22). The tapered portion 22b is gradually formed to have a narrow water flow cross section, and is a portion where the water discharge port 22a is provided.

On the other hand, the air supply unit 9 according to another embodiment of the present invention shown in Figure 4 has a through hole 90 having the same inner diameter for a certain section, a plurality of discharge holes (branched from the through hole 90 ( 90a). Each discharge hole 90a disperses the water and air guided in the discharge hole 90a to various positions in the water, thereby effectively purifying the contaminated water.

Hereinafter, the operation of the water purification aeration system according to the present invention will be described in detail.

When the pump 11 is operated to allow the water in the water to flow into the first water pipe 21 through the water inlet 12a, the water introduced into the first water pipe 21 is transferred to the first water pressure balance tank 31. It is discharged and stored temporarily. After the water is stored in the first water pressure balance tank 31 for a predetermined time, the stored water flows into each of the second water pipes 22 branched at about the same time after a certain time.

In this case, water flows into only one of the second water pipes 22, thereby preventing the water from being discharged only to the water discharge port 22a side of the second water pipes 22. As a result, water can be discharged uniformly to the water discharge port 22a of each second water pipe 22, so that the contaminated water in the water can be purified efficiently.

Of course, in the present invention, the second hydraulic pressure balance tank 41 is provided at the point where each of the second water pipes 22 branches into several branches, thereby making it possible to more efficiently purify the contaminated water in the water.

Here, when water is discharged to each of the water discharge ports 22a, each of the second water pipes 22 is provided with a taper portion 22b in which the water flow cross-sectional area gradually narrows, so that the water on the water discharge port 22a side of the water discharge port 22a is provided. The flow rate will be faster.

In this case, the pressure on the air discharge port 62a side disposed adjacent to the water discharge port 22a side becomes relatively lower than the air inlet port side by the Bernoulli principle, thereby introducing air in the air into the air inlet duct 51. It will be able to flow smoothly.

Here, looking at the process of discharging the air in the air to the air discharge port 62a, when the air in the air flows into the air inlet duct 51 as described above, the fan 52 is rotated by the inflow of the air. The introduced air is temporarily stored in the air pressure tank 7, so that the discharge of the air can be prevented from being disturbed by the disturbance.

That is, when the second water pipes 22 and the second air pipes 62 flow up and down in water due to a sudden change in the water flow, the pressure on the air discharge port 62a side is less than the required pressure to discharge the air. In this case, the discharge of the air cannot be expected, but a large amount of air is stored in the present invention, and the forced air can be supplied to enable the discharge of the air to the respective air discharge ports 62a.

Of course, in addition to the air pressure tank (7), in the present invention, the first pneumatic balance tank (32) is provided at a position where air is branched to each of the second air pipes (62), so that even when the disturbance as described above occurs, The discharge can be expected more. Similarly, the second pneumatic balance tank 42 is provided at a position where air is branched to each air discharge port 62a, so that smooth air can be discharged and the polluted water in the water can be efficiently purified.

On the other hand, since the air direction in the atmosphere changes every time, the air inlet duct 51 is required to rotate in accordance with the wind direction in order to allow the air in the air to smoothly flow into the air inlet duct 51.

However, in the present invention, there is provided a rotating member 53 extending downward to be rotatably coupled to the air pressure tank 7 at a position corresponding to the center of gravity of the air inlet duct 51. Therefore, since the area in which the wind power acts on the basis of the center of gravity is different, the air inlet duct 51 can be rotated according to the wind direction. In this case, a large amount of air can be introduced into the air inlet duct 51.

Here, the air introduced into the air inlet duct 51 is introduced into the air pressure tank (7), the reverse flow of air generated by storing a large amount of air in the air pressure tank (7) is a check damper (54) To be prevented. When the fan 52 rotates as the air flows into the air inlet duct 51, the fan 52 is continuously rotated by the rotational inertia even when the wind speed is small, thereby reminding the air around the air inlet side. The air inlet duct 51 can be introduced into the inside.

Of course, the fan 52 is also rotated by the pressure difference between the air inlet and the air discharge port 62a in addition to the case where the fan 52 is rotated by the rotational inertia, to guide the air around the air inlet side to the air inlet duct 51. It becomes possible.

Now, look at the action of the air supply unit 8 shown in Figure 3 constituting an embodiment according to the present invention, the through hole 80 in the air supply unit 8, the tapered portion (2) of the second water pipe 22 It is formed with the same diameter longer than 22b), and the water and air which are discharged to the water discharge port 22a and the air discharge port 62a to become a turbulent state are made into a laminar flow state. In this way, water and air are made into a laminar flow state and finally discharged into water, so that the loss of the discharged air can be suppressed.

In addition, referring to the operation of the air supply unit 9 shown in FIG. 4 constituting another embodiment according to the present invention, the air supply unit 9 has a through hole having the same inner diameter as that of the through hole 80 over the same section. 90 is formed, and a plurality of discharge holes 90a branched from the through holes 90 are provided to disperse air to various positions in the water. In this way, contaminated water in the water can be efficiently purified.

The invention is not limited to the embodiments described above but is defined by the claims, and it is obvious that various modifications and adaptations can be made in the art.

The following effects are expected in the water purification aeration system according to the present invention having the configuration described above.

That is, in the present invention, the water pressure balance tanks are temporarily stored before the water flowing from the water inlet is discharged to the water outlets, so that the water is smoothly discharged to each water outlet, thereby smoothly discharging air to each air outlet. You can expect. Therefore, in the present invention, there is an effect that can effectively purify the water in the contaminated water.

In the present invention, pneumatic balance tanks are temporarily stored before water introduced from the air inlet is discharged to the air outlets, so that air is smoothly discharged to each air outlet so that air can be smoothly discharged to each air outlet. You can expect. Therefore, in the present invention, there is an effect that can effectively purify the water in the contaminated water.

 On the other hand, in the present invention, the air inlet duct rotated in accordance with the wind direction and the fan for guiding the air in the air to the air inlet duct and the air pressure tank that can temporarily store a large amount of air smoothly to the air outlet side, respectively By discharging, there is an effect of more effectively purifying the contaminated water.
