Liquid gas mixing device

The present invention relates to a liquid-gas mixing device, and more particularly to a liquid-gas mixing device for increasing underwater oxygen content.

The breeding industry in various countries is developed, and a variety of aquatic animals and plants have been cultivated. However, since the general breeding areas are mostly pools constructed by enclosures, the oxygen solubility in the water is easily consumed. When the amount of oxygen dissolved in the pool is too low, not only will the organism not be able to absorb enough oxygen to die, but also the biological excretion in the water cannot be digested by the nitrifying bacteria, affecting the quality of the pool, causing the organism to be unhealthy or the number of deaths. increase.

In order to solve the problem of too low dissolved oxygen, some operators have developed underwater aerators or liquid-gas mixing devices, which mainly use the structure of the water-pumping vehicle, tapping the water surface to make the pool water contact with the air and increase the dissolved oxygen amount. The method is more noisy, consumes more power, and has a limited effect of increasing the amount of dissolved oxygen.

For the static application, please refer to FIG. 8. FIG. 8 is a schematic cross-sectional view showing a liquid-gas mixing device 140 according to an embodiment of the static type of the present invention.

If the underwater unit is in the shape of a rectangular parallelepiped and the angle between the center of the virtual line and the depth of the water is less than 90 degrees, and then the symmetrical arrangement of the upper and lower tubes is used, the underwater unit can be driven by the motor to rotate clockwise or counterclockwise, thereby driving the water flow and the air bubble to rise. Or sinking, which helps the circulation of water and is more conducive to the increase of dissolved oxygen.

4. In the dynamic application, when the liquid-gas mixing device of the present invention further comprises a protective cover, the underwater creature can be prevented from being damaged by being caught in the underwater unit, and the water-blocking member can restrict the water flow only from approaching. The water surface is located at and near the subsea unit, thus facilitating the circulation of water. When the protective cover further comprises a connecting member disposed at one end of the submerged water portion away from the exposed portion, the connecting member can be extended to the bottom of the water to drive the water flow at the bottom into the underwater unit to increase the circulation of the water at the bottom.

5. In the static application, the liquid-gas mixing device of the present invention can be placed underwater under the underwater unit and matched with a submersible motor. Directly pressurize the water stream to make the flow rate faster and speed up the generation of microbubbles.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Any one skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
