Description

Water tank aerator with air compressor and impeller stirring water flow

The invention relates to an aerator, in particular to a water tank aerator which can increase the oxygen content of a bottom layer of a water body and combines an air compressor and an impeller to agitate the water flow.

In order to improve the oxygen content of water bodies, the aquaculture machine will place aerators in the culture ponds. With the different design principles, the common aerators can be basically divided into waterwheel type, disc type, deep water type and exposure. Different forms such as gas. The waterwheel aerator basically comprises a stage which can float on the water surface, a driving mechanism mounted on the stage, and two impellers which are bilaterally symmetrical and rotated by the driving mechanism. When the impellers are driven to rotate, a plurality of blades of each impeller can dial the water body adjacent to the water surface, and disperse the water body into fine water droplets, and throw them into the air to contact with the air, when the water drops fall into the breeding pool. The oxygen in the air can be brought into the water body, so that the oxygen content of the water body can be increased.

Although the conventional water tank aerator has the above-mentioned effects, the blades of the impeller can only agitate the water near the water surface. Therefore, although the oxygen content of the upper and middle layers of the culture tank can be increased, it is adjacent to the culture. The oxygen content of the water at the bottom of the pool has no effect. Although the conventional deep-water aerator can change the oxygen content of the water near the bottom of the pool, in order to achieve the above objectives, it is necessary to purchase an aerator with different design principles, which not only has a high purchase cost but also requires different powers. The cost of use is higher.

The pressure aeration mechanism 5 is actuated. Since the air pressure aeration mechanism 5 of the present invention is directly erected on a general water tank type aerator, the present invention has the advantages of convenient installation and low installation cost, since the air pressure aeration mechanism 5 directly mounts the drive. The upper portion of the mechanism 3 is located above the water surface 1, and therefore, the aerator has a convenient maintenance effect.
