Description

1274544 IX. Description of the Invention: [Technical Field] The present invention relates to an aeration device, and more particularly to a method for feeding water in the vicinity of a surface layer to a bottom layer of a pool to increase the temperature of the bottom pool water and promote the water circulation of the pool. An aeration device that increases the oxygen content of the bottom pool water. [Prior Art]

Aquaculture ponds or fishing rods need to maintain the concentration of pool dissolved by aeration devices to maintain the aquaculture, aquatic organisms and microbial respiration. Second, it is necessary to stabilize the water quality and maintain the ecological balance of the fish pond. The traditional inversion device uses an electric motor to drive the waterwheel, and the motor drives the impeller of the waterwheel to pour water into the air, thereby increasing the contact time and surface area of the water and the air, and promoting the oxygen in the air to dissolve in the water to reach the gas. Increase the purpose of dissolution. Although the conventional waterwheel installed in the breeding pond has the effect of aeration and increasing dissolved oxygen, the above-mentioned aeration and oxygen supply by the waterwheel can only increase the dissolved oxygen amount of the pool water near the surface layer, and cannot increase the dissolved oxygen of the bottom layer. Some benthic organisms that live in the bottom of the culture pond, such as shrimp, shellfish and crabs, are effective in increasing the amount of dissolved oxygen in the bottom layer, and in the case of the health of the bottom (four) t health, it is also affected by the anaerobic The breeding of the bacteria = the deterioration of the larvae of the larvae, so that the density of the water in the culture pond can not be increased. It is difficult to meet the demand for high-density farming. The aeration effect of the owed/1^ waterwheel is only limited to the larger waters in the waters near the aeration device. At least the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In this way, not only does it require considerable power resources, but the cost of setting up multiple conventional waterwheels is also increasing.曰 Therefore, it is necessary to develop a method that saves costs, consumes less power, has high aeration efficiency, promotes pool water circulation, and greatly increases water-soluble oxygen in the bottom pool to balance the economic and environmental protection of the fishermen. ",, [invention content]. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an aeration device which has the characteristics of low lift and large aircraft and can be placed in any position in the pool in any suitable manner. By directly extracting the pool water near the surface layer and spraying it down to the bottom layer in large quantities, the convection of the surface pool water and the bottom pool water is increased by the forced circulation of the water stream, and the warmer and high oxygen content pool water near the surface layer is sent to the bottom layer 2 bottom pool water. To increase the temperature, the water density of the pool is changed by the water temperature difference to generate a machine to promote the water circulation of the pool, and the surface pool water is exchanged with the bottom layer and the middle pool water to adjust the oxygen concentration of the pool water at different depths in the pool (j〇nCentration). In this way, the conventional waterwheel can be improved only by aeration on the surface of the pool water, and it is difficult to dissolve the dissolved oxygen in the water to effectively increase the dissolved oxygen content of the bottom pool. Yet another object of the present invention is to provide a self-moving low lift large flow aeration 5, in addition to directly extracting pool water near the surface layer and spraying a large amount down to the bottom layer for adjusting different depths in the pool. The oxygen content of the pool water can also be circulated in a specific direction in the pool, which can reduce the demand for aeration damage per unit area, and improve the exposure of the traditional fixed aerator. 6 1274544
