Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying apparatus for purifying water having a large capacity and a large depth.

[0002]

2. Description of the Related Art Conventional intermittent air pumping equipment allows dams,
It is known to improve purified water and dissolved oxygen content in lakes and marshes, and it has a great effect. Also, a composite pumping cylinder has been proposed for a large capacity (for example, tens of millions of tons or more) dams, lakes and marshes (Actual No. 60-176300).

[0003]

However, in the conventional pumping cylinder, the algae that propagate in the shallow water layer are caught in the bottom of the water (deep water layer) and retained in a position where light does not reach relatively, so that the algae are killed or weakened. The water is purified by making it. Therefore, there is a problem that the purpose of water purification cannot be achieved when there are few deep water layers or when fine solid particles (for example, clay particles) cause pollution.

Further, when the water depth becomes large (for example, water depth 30
(m or more) If the air chamber is installed at the lower end of the pumping cylinder, it is necessary to supply air against the water pressure, which causes a large and large capacity of the air supply device, which increases running costs. was there. Further, when air is supplied to each of the plurality of pumping cylinders to float inside the pumping cylinder as a bubble can, it is preferable that the bubble can be released from each pumping cylinder at the same time, but there is a problem that the adjustment is difficult. .

[0005]

According to the present invention, however, an air chamber is fitted in the lower part of a plurality of pumping cylinders, a large diameter pumping cylinder is connected to the lower end of the pumping cylinders, and a chemical injection means is provided. The above-mentioned conventional problems are solved by providing the self-supporting means.

That is, according to the present invention, an air chamber for supplying pressurized air to each pump is fitted and installed outside the lower part of the pumps, and the upper end of a large-capacity pump is connected to the lower end of the pump. However, the water purification apparatus is characterized in that the plurality of pumping cylinders are provided with an independence means in water. Still another invention is to install and install an air chamber for feeding pressurized air to each pumping cylinder outside the lower part of a plurality of pumping cylinders, and connect an air storage chamber to the air chamber,
The water purification apparatus is characterized in that an upper end of a large-diameter pumping cylinder is connected to a lower end of the pumping cylinder, and a medicine supplying means and a self-supporting means in water are provided to the plurality of pumping cylinders. Next, in another invention, the medicine supply means is one in which a chemical injection hose is connected to a part or all of a plurality of pumping cylinders, and the self-supporting means of the pumping cylinder has a float attached to the upper part and a weight attached to the lower part. It was done.
The large diameter pumping cylinder is a cylinder or an expandable and contractible bellows cylinder.

As the chemical injection means in the above, in addition to the above, for example, a medicine basket can be connected to the upper part of a pumping cylinder, and ascending water can be circulated in the medicine basket to elute the medicine. In addition, a number of modified structures are conceivable, such as providing a chemical injection chamber on the outer wall of the pumping cylinder, forming a small hole between the pumping cylinder and the chemical injection chamber, and automatically injecting it. Any structure that can be easily used belongs to the scope of the present invention.

The water depth position of the air chamber is appropriately determined, but the shallower the better, as long as it does not significantly lower the pumping efficiency of the amount of rising water. This point has a correlation with the diameter of the pump. For example, a pumping cylinder with a diameter of 10 cm is 1 m
The above length is required, and a pump with a diameter of 40 cm is 3 m
The above length is required. If the pump is deep and has a large capacity, a diameter of 40 cm or more is preferable.
Inevitably, a length of 3 m or more is required, and the water depth of the air chamber is the sum of the distance between the top of the pump and the water surface (for example, 1 m to 5 m, sometimes 10 m) and the required length of the pump. Therefore, the water depth will be approximately 5 m or more.

[0009] In addition, since a large-diameter pumping cylinder is connected in order to reduce water flow resistance and to pump water from a planned depth layer, in order to achieve the purpose, it is usually one, but in terms of strength. It is possible to reinforce the inside and outside.

[0010]

According to the present invention, since the air chamber can be installed at the relatively upper portion, the feed air pressure can be made as low as possible. In addition, since it is possible to dosing by chemicals, not only algae killing but also fine particle solids can be aggregated and purified by precipitation.

Further, by utilizing the air storage chamber, it is possible to adjust the levitation of the bubbles from each pumping cylinder.

The upper ends of the water bottles) are connected to communicate with the respective water pumps 1.

The lower end flange 21 of the cylinder 5 is provided with a cord 6
The weight 9 is connected via.

A step portion is provided on the outer periphery of the upper portion of the air chamber 4, and the air storage chamber 7 is fitted and fixed to the step portion, and the air storage chamber 7 and the air chamber 4 are communicated with each other by communication holes 8 and 8. Let

The air chamber 4 is constructed by loosely fitting an outer cylinder 11 outside the inner cylinder 10 at a predetermined distance and inserting a partition cylinder 12 between the outer cylinder 11 and the inner cylinder 10. Communication holes 14, 14 are provided between each pumping cylinder 1 and the inner chamber 13, a communication hole 16 is provided between the inner chamber 13 and the intermediate chamber 15, and a communication hole 18 is provided between the intermediate chamber 15 and the outer chamber 17. In the figure, 19 is a closing plate that closes the gaps between the pumping cylinders 1, and 20 is a chemical injection hose that is connected and opened to each pumping cylinder 1.

In the above embodiment, when pressurized air is supplied from the air supply hose 22 as shown by the arrow 23, the air is filled in the air storage chamber 7 and enters the air chamber 4 through the communication holes 8, 8. , The water level in the air chamber 4 is pushed down as shown by the arrow 24 (FIG. 4). In this way, when the water level reaches the chain line 25,
The air in the air chamber 4 is shown by the communication holes 18, 16 and 14 in the direction of arrow 2.

The water inside rises as shown by arrow 31.

On the other hand, a small amount of a drug (coagulant or algaecide) is injected from the chemical injection hose 20 into each pump 1 and mixed with the rising water to be sprayed from the upper end of the pump 1 (FIG. 1). ).

The water jetted up as described above rises up to the water surface 32 as indicated by an arrow 33, and then diffuses into four circles as indicated by an arrow 34.

In this case, the water on the water bottom side has a large specific gravity and the water on the water surface side has a small specific gravity, but the jetted water and the water on the water surface are mixed with each other, and the mixed water has a slightly higher specific gravity than the water near the water surface. Become.

Then, the radial diffusion water advances in a depth corresponding to its specific gravity as shown by an arrow 35. In this way, the diffused water descends as shown by the arrow 36 near the shore, and further flows as shown by the arrow 37 near the bottom of the water to be in a recirculation state as a whole.

Therefore, the chemicals contained in the pumped water also flow and diffuse into the whole water area, so that the fine particles are aggregated (or algae killed), and the oxygen-rich water near the water surface is circulated to the water bottom to make the whole as a whole. It increases the amount of dissolved oxygen.
