Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a simple water purification device used in artificial ponds and the like where the flow of water is small and the water easily becomes stagnant and polluted.

[Conventional technology]

In ponds with low water flow, such as artificial ponds at golf courses, if the water is not constantly purified, it will easily become stagnant and dirty, and a large amount of harmful moss such as blue-green algae will grow, causing the water to corrode. Not only did it have a negative impact on the fish that lived there, but it also emitted a foul odor, and the floating leaves and garbage made it extremely inconvenient for the landscape.

With regard to activating water, for example, for eel farming ponds, the inventor of the present invention previously proposed the invention published in Japanese Patent Publication No. 61-36448 as an invention for mixing liquid and gas.
No. 2 was proposed.

[Problem that the invention attempts to solve]

The invention disclosed in this Japanese Patent Publication No. 61-36448 is
The high-speed rotation of the rotating body in the water is used to create violent vortex motion in the water, and this violent vortex motion violently stirs and mixes the water and air, causing the air to float in extremely small bubbles in the water. It is said to have an extremely high water purification effect.

However, the water purification device disclosed in Japanese Patent Publication No. 61-36448 cannot be used in places such as golf course ponds where it is sufficient to simply maintain a certain level of water quality.
Its water purification capacity is larger than necessary, resulting in waste, and the driving part for driving the rotating body to rotate at high speed underwater is placed directly above the water surface, so A part of the water purification device will be exposed above the water surface, which will harm the appearance of the pond.Furthermore, this type of pond will contain unnecessary floating foreign matter such as fallen leaves, paper scraps, etc. It had no ability to exert any action that would help remove foreign matter.

For this reason, in the case of ponds on golf courses, the only equipment for water purification is a fountain, and it is not possible to effectively prevent the deterioration of the water quality of the water in the ponds, and large amounts of water are regularly generated. They spent a lot of money and man-hours replacing the water in the pond and digging out the bottom.

This invention was devised to solve the problems and inconveniences of the conventional examples described above, and by generating a forced vortex under the water surface, it promotes the dissolution of air into water, and at the same time promotes the dissolution of pond water. The technical problem is to form a nearly constant water flow and to concentrate this water flow at a fixed water surface point.

[Means and actions for solving problems]

Hereinafter, the present invention will be explained with reference to the drawings showing one embodiment of the present invention.

The water purification device of the present invention includes an outer cylinder body 1 and a rotating body 2.
and a net body 6.

The outer cylindrical body 1 has a cylindrical shape with a length of 50 cm or more and is installed in an upright position in water with the upper end opening located directly below the water surface. They are inserted and assembled into a core at regular intervals, and are rotated by an underwater motor 5 connected to the lower end.

The net body 6 is assembled and arranged to cover the upper end opening of the outer cylinder body 1 with a portion of the net body 6 protruding above the water surface.

In the above configuration, water from the pond enters the gap formed between the outer cylinder 1 and the rotating body 2, and the rotating body 2 is rotated via the submersible motor 5. Then, water flows in from the upper end of the outer cylindrical body 1 and is discharged from the lower end, and a vortex is generated within the gap. Since the upper end opening of the outer cylinder 1 is located just below the water surface, gas enters as the water flows in, the gas and water are stirred and mixed, and are released from the lower end of the outer cylinder 1. Become.

Therefore, the water in the pond is mixed with air by the device of the present invention and released in all directions from the opening at the lower end of the outer cylinder 1 in a state containing a large number of thin air bubbles, and this release creates an almost constant water flow. The air flows along the water, and the large number of thin air bubbles that it contains allows the air to dissolve into the water efficiently.
Not only can it strongly inhibit the growth of blue-green algae and prevent water from rotting, but it can also promote water purification.

In addition, the water in the pond is
Since the water is sucked into the outer cylinder 1 from the upper opening and released in all directions, the water flow generated in the water of the pond by this device of the present invention is concentrated at the upper opening of the outer cylinder 1 at the water surface. Therefore, floating foreign matter on the water surface inevitably moves toward the upper end opening of the outer cylinder 1 along with the water flow. Since the net 6 is disposed at the upper opening of the outer cylinder 1, floating foreign matter that has moved along with the water flow on the water surface will be captured by the net 6. Therefore, by periodically removing floating foreign matter captured by the net 6, almost all of the floating foreign matter that enters the pond can be reliably removed.

Furthermore, since the rotating body 2 is rotationally driven by an underwater motor 5 connected to its lower end, the device of the present invention installed in a pond can only expose a part of the net 6 above the water surface while all other parts are exposed. Since this part will be submerged in water, the scenery of the pond will not be harmed at all by installing the device of the present invention.

The length of the outer cylindrical body 1 must be approximately 50 cm or more, and the reason for this is that the vortex generated between the outer cylindrical body 1 and the rotary body 2 effectively stirs water and air. The purpose is to form into thin bubbles,
If the length of the outer cylindrical body 1 is less than 50 cm, the water and air will be released from the opening at the bottom of the outer cylindrical body 1 before the water and air are sufficiently stirred by the vortex flow. This is because it becomes impossible to form many thin air bubbles in the water.

〔Example〕

In the illustrated embodiment, the rotating body 2 has a structure in which end plates are arranged at both the upper and lower ends of a cylindrical body, and a shaft 3 protruding from the center of the lower end is connected to an underwater motor 5. It is housed in a predetermined box-shaped support 4, and a power source is obtained by connecting it to other predetermined outlets installed around it.

The support body 4 stands on the bottom of the pond in a stable position by means of a plurality of supporting legs 11.

The outer cylindrical body 1 has connecting legs 10 connected to the plurality of supporting legs 11.
The rotary body 2 is attached at a predetermined distance from the rotating body 2.

Next, the net body 6 has a top portion 7 formed by a net plate.
It has an umbrella shape with a surrounding part 8 made of a similar net plate suspended around it, and the entire area of the top part 7 and the upper part of the surrounding part 8 protrude above the water, and it is attached to the outer cylinder body 1 via the holding legs 9. and covers the upper end opening of the outer cylindrical body 1.

Therefore, when the rotating body 2 is rotated, water in the pond enters the outer cylinder 1 from the lower part of the surrounding part 8, and as this water flows from the upper end to the lower end of the outer cylinder 1, it floats on the water surface. Debris that is floating is caught at the lower part of the peripheral part 8 of the net 6 by the flow of water at the water surface, and air flows in through the top part 7.

In addition, by providing a net between the lower end of the peripheral portion 8 and the outer cylinder 1, it is possible to eliminate the risk of fish, etc. in the pond being drawn between the outer cylinder 1 and the rotating body 2.

Also, according to experiments, the most suitable one that can currently be used as the underwater motor 5 has a rotation speed of
It does not exhibit a high rotational speed of about 3000 rpm, but in order to stir water and air with the vortex generated between the outer cylinder 1 and the rotating body 2, it is necessary to rotate the rotating body 2. Since the circumferential surface speed needs to be at least a certain level, for example at least 6 m/sec, the outer diameter of the rotating body 2 is preferably 4 cm or more, preferably 5 to 6 cm.

However, as a practical underwater motor, although expensive, 7000rpm and even
There are also models with a speed of 11,000 rpm, and when using an underwater motor capable of high-speed operation like this, the rotating body 2
This means that it is possible to use one with a small outer diameter. A rotating body 2 with a small outer diameter,
That is, being able to use a lightweight device means that there is less risk of undesirable vibrations occurring in the rotating body 2 due to high-speed rotation, and it is possible to obtain a device that is compact and has high water purification ability.

In this way, in the illustrated embodiment, the outer cylinder 1, the rotating body 2, the support 4, the underwater motor 5, the net 6, etc. are integrated, which is convenient for handling and easy to install and clean. Become something.

By the way, when actually using the device of the present invention, it is difficult to generate a constant water flow throughout the entire pond using only the device of the present invention.
The water purification effect of the device of the present invention will be more effective if the jet jet device is placed at an appropriate location, such as a location where water tends to stagnate, to form a nearly constant water flow over the entire area of the pond. It turns out.

[Effect of idea]

As is clear from the above explanation, according to the device of the present invention, the water in the pond can be appropriately stirred, so the upper water flows to the lower part and does not settle, so it is always fresh and algae. It does not cause corrosion, odor, or odor, creating favorable conditions for the fish that live there.Furthermore, it is possible to easily remove debris floating on the water surface. Since it is installed almost entirely submerged in water, it does not harm the landscape of the pond at all, has a simple structure, can be manufactured at low cost, and is easy to use, and has many excellent effects.
