Abstract

The present invention provides a wave aeration device for culture pond with surface and bottom layer circulation and turbulence, which is to configure an auxiliary impeller and a rotary water stirring assembly with buoyancy and capable of floating on the water surface on top of a submerged motor sunk into a culture pond. When the submerged motor pumps the pond water at bottom layer and utilizes the water flow to drive the auxiliary impeller, the power generated by the rotation of the auxiliary impeller may drive and rotate the water stirring blades of the water stirring assembly to disturb the water surface and rotate to form a wide range of wave, which cannot only increase the amount of dissolved oxygen in water, but also enable the pond water at bottom layer flowing toward the upper layer, and thus exchange the pond water between surface layer and bottom layer in circulation. By contacting the surface layer with the air, the excess carbon dioxide may be dissipated into the air, and the oxygen may be dissolved in the water at surface layer and then uniformly distributed around the culture pond. Moreover, the present invention employs the water flow to drive and rotate the water stirring assembly with no need of a speed reduction mechanism, so as to further effectively extend the service life, and reduce the manufacturing and maintenance costs.

Description

Wave-type aerator for circulating circulation at the bottom of the culture pond

The present invention is an aeration device for applying a rotating water-discharging component to a water in a culture pond, especially an aeration device capable of disturbing a wave on the water surface to increase the dissolved oxygen amount, and circulating the surface layer and the bottom layer water.

In general, the culture tank will install a water tank aeration device on the surface of the pool water to accelerate the dissolution of oxygen in the air into the water to increase the dissolved oxygen content of the pool water. The conventional water tank aeration device is divided into a vertical axis or a horizontal axis according to the axial direction of the blade, wherein:

The horizontal axis water tank aeration device is provided with a motor floating on the surface of the water surface of the culture tank and a speed reduction mechanism coupled with the motor. The speed reduction mechanism has horizontal drive shafts extending on both sides thereof, and vertical rotations are respectively arranged on both ends of the horizontal transmission shaft The blade assembly; the motor drives the two-side blade assembly to rotate vertically through the speed reduction mechanism, so that each blade on the blade assembly generates a large amount of water splash by tapping and impacting, increasing the contact area between the pool water and the air, and allowing the air to be dissolved into the pool water. Increase the dissolved oxygen of the pool water.

Although the horizontal axis water tank aerator can be used in large quantities for the aquaculture industry, the power transmission is to convert the motor kinetic energy into potential energy, and then use the position of the blade assembly to vertically pat the water surface for a long time operation. It consumes electricity and does not meet the economic benefits it deserves.

Another vertical axis water tank aeration device also has a motor and a speed reduction mechanism, and the speed reduction mechanism has a vertical transmission shaft extending downward, the vertical transmission The moving shaft is respectively provided with a horizontally rotating blade assembly; the motor drives the blade assembly to rotate horizontally through the speed reducing mechanism region, so that the blade assembly agitates the water surface to form a wave, so that the air is dissolved into the pool water, and the dissolved oxygen amount of the pool water is increased. For example: Taiwan's new type M429775, which is a vertical axis water tank aeration device.

The vertical axis water tank aeration device has less kinetic energy loss than the horizontal axis aeration device because it does not need to convert kinetic energy into potential energy during operation, but in operation, it increases the dissolved oxygen in a wave pattern. The amount is limited to the surface layer of the water surface and cannot exchange the pool water at the bottom of the pond. Therefore, the carbon dioxide at the bottom of the pond water does not easily escape upward in the air, and the oxygen in the surface layer cannot convect downward. The effect of oxygen is limited.

Furthermore, both aerobic devices must reduce the motor speed through a speed reduction mechanism (gearbox) to increase the torque to allow the blade assembly to push the water flow. However, the long-term operation of the speed reduction mechanism is prone to heat and in a humid environment, even if it is Waterproof treatment is still very easy to cause malfunction due to problems such as oxidation of the parts caused by heat and moisture, and dampness of the circuit, which causes considerable trouble to the aquaculture industry.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and created an oxygen-increasing device that not only overcomes the shortcomings of the deceleration mechanism, but also pushes the bottom pool water upwards into the surface water.
