Description

Dissolved oxygen amount increasing type bubble generating device {BUBBLE GENERATING APPARATUS FOR INCREASING DISSOLVED OXYGEN}

The present invention relates to a bubble generating device for increasing the amount of dissolved oxygen, and more particularly, by discharging a large amount of fine bubbles directly into the water of a farm or lake, thereby increasing the amount of dissolved oxygen in the farm or lake, thereby increasing the amount of dissolved oxygen that can increase the efficiency of water quality purification. It relates to an augmented bubble generating device.

In general, as water purification methods for purifying water quality of reservoirs or freshwater lakes, a method of purifying water quality using chemicals, a method using organisms, and a composite method using both the chemical and biological methods are known.

However, in the case of a chemical water purification facility or a biological sewage or wastewater treatment facility using such chemicals, a huge initial capital must be invested, and there is a serious concern about environmental destruction during the construction of the facility, and in most cases, the above treatment In the case of installing facilities, it is a situation that is experiencing difficulties due to strong opposition from local residents and private environmental groups.

Therefore, the need for water purification using an economical and environmentally friendly technique is gradually emerging, and for this purpose, a method using a plant island for purification by planting plants in an artificial structure has been disclosed and applied.

However, it costs considerably to install the artificial structure, and the buoyancy is reduced due to the growth of aquatic plants, causing the artificial structure to sink into the water.

Accordingly, the present applicant, through Korean Patent Registration No. 10-1301267, makes the water in the water soar like a fountain to increase the amount of dissolved oxygen in the water, and also causes the water near the bottom of the water to rise to the outside, so that the water flows through the water. A water purification device that prevents corruption has been proposed.

However, since the conventional water purification device is configured to spray water in all directions while the impeller is rotated by the driving force of the driving motor, when the area of the lake in which the water purification device is installed is small, the scattered water is scattered in the grass or trails around the lake. It is scattered to the outside of the lake, such as a situation that causes damage to nearby facilities or lake users.

Moreover, a high-output drive motor is used to rotate the impeller. Due to the nature of the water purification device that is continuously operated for a long period of time, noise-related complaints from neighboring private houses are continuously raised due to the noise caused by the driving of the high-output drive motor in the evening. As the damage to crops is increasing, the development of technology for this is urgently needed.

In addition, the conventional water purification device has a complicated structure, so the manufacturing cost is increased, as well as the increase in maintenance cost due to frequent breakdowns and the decrease in water purification efficiency due to the extension of maintenance time.

The present invention was devised in view of the above situation, and an object of the present invention is to directly discharge a large amount of microbubbles into the water of the farm or lake to increase the dissolved oxygen content of the farm or lake to increase the efficiency of water purification, By forming a bubble film on the lower side of the opening of the concentrated jet unit accommodating the impeller member, it is possible to effectively prevent the adult fish or fry of the farmer from entering the inside of the concentrated jet unit.
