Description

Height-Adjustable Intermittent Underwater Equipment {Adjustable-Height Air Lifter}

The present invention is installed in the water such as the easy to stagnate appeal, and the height adjustable intermittent underwater aerator configured to maintain a constant aeration depth irrespective of the fluctuation of the water level, aeration of the compressed air supplied from the land at a time in deep water The present invention relates to a height adjustable intermittent underwater aeration apparatus capable of performing water quality improvement of the appeal by pumping the water and pushing the surface water around and stirring the entire appeal.

In general, lakes and reservoirs that have stagnant water with little flow, such as lakes and reservoirs, have a stratification of the lakes compared to rivers with relatively fast water flow, and it is difficult to mix the surface and deep layers of the lakes. In these appeals, problems such as overgrowth of algae on the surface and odor generation, aesthetic disorders, and water purification problems at intake sources occur at certain times of the year, and algae proliferation in the upper layer of the appeal and odors may occur frequently. . In addition, the deep part of the appeal may deplete dissolved oxygen due to the decay of various sediments and organic matter precipitated from the outside, etc. As a result, eutrophication is promoted by eluting nutrients such as phosphorus and manganese. This is repeated.

In order to prevent water pollution of such an appeal, as an apparatus generally used among various apparatuses, an intermittent underwater aerator which is an artificial circulation method of an appeal is known. The device has a hollow body, a fixed weight connected to the lower part of the main body by a fixed length rope and wire rope and fixed to the bottom of the appeal, and the air supplied from the air compressor is located at the lower part of the main body so that the special diving air It includes an air chamber to which the supply hose is connected, a float acting so that the main body is standing upright in the water, and a position indicating buoy which is floated on the surface to indicate the installation position of the intermittent underwater aerator.

The body is made of a hollow body to provide an upward passage of compressed air that is intermittently released. The air chamber functions to discharge compressed air, which is compressed and supplied at high pressure on land and temporarily stored, temporarily into the water from the main body at a time in a warhead shape. At this time, the warhead-type bubble discharged into the water rises while raising the water in the lower part of the height adjustable intermittent underwater aerator as described above and pushing up the water in the upper part of the bubble. The water in the upper layer is repeatedly diffused in the horizontal direction, so that the water in the entire layer is mixed and circulated eventually.

Therefore, by injecting compressed air into the water, the lower layer of water is pulled upwards and the entire appeal is agitated, so that the dissolved oxygen concentration in the lower layer is increased while algae in the upper layer, especially cyano algae, which cause odors, are moved to the lower layer to block sunlight. As a result, the growth of algae is suppressed, and the occurrence of odor by algae can be prevented.

Recently, a height-adjustable underwater aerator has been used in which its length (height) is flexibly adjusted according to the level of the appeal.

The device is provided with a cylindrical height-adjustable underwater aerator, which is erected in the water by buoys and anchoring weights, and is provided with a water level spacing tube which slides into the body according to the water level, and the water level spacing tube floats on the water through the wire rope. Is connected to a buoy. Therefore, when the height of the water surface of the appeal increases due to weather conditions such as rainy season or drought, the water level gap control tube slides upward from the main body because the water level gap control tube is connected to the buoy floating on the water surface. Thus, the length of the main body is increased in accordance with the water level.

However, the conventional height-adjustable underwater aeration apparatus as described above has a structure in which the length is adjusted by sliding to the main body by the weight of several water level interval control tubes when the water level is lowered, so that the main body and the water level interval The foreign matter is caught between the control tube in a short time, the height of the height adjustable underwater width device is impossible to control the device performance is difficult and there is a problem that the stirring ability is lowered.

In addition, the conventional height adjustable underwater aeration apparatus is connected to a special diving air supply hose on the upper air chamber, the compressed air supplied to the air chamber is filled in the air chamber, the induction pipe formed in the vertical direction in the air chamber Therefore, it has a structure that rises at a time. However, in the structure as described above, since the guide tube is formed in the vertical direction of the U-shape, due to the residue bubble generated as the warhead-shaped bubble is formed to be wide and vertically raised to the inner diameter of the guide tube There was a problem that the pumping capacity and the stirring ability is lowered.

Accordingly, it is an object of the present invention to provide a height adjustable intermittent underwater aeration apparatus having a structure capable of maintaining an optimal depth of aeration in accordance with the fluctuation of the water level to be installed to provide an optimum pumping and stirring ability.

Another object of the present invention is to provide a height adjustable intermittent underwater aerator having a structure that can prevent the generation of residues during aeration to improve the pumping capacity and stirring ability.
