Microporous aeration and oxygenation device for aquaculture production

Abstract

The invention discloses a microporous aeration and oxygenation device for aquaculture production. The microporous aeration and oxygenation device comprises supporting plates, rotating paddles, hollow floating balls, rotating blades and a fixed frame; the fixed frame is installed at the center positions on the supporting plates; a power shell is fixed at the center position on the fixed frame; a motor is installed at the center position in the power shell; a worm is installed in the power shell below the motor; a rotary shaft which penetrates through the power shell is installed above the fixed frame on one side of the power shell through a bearing; the rotating paddles are installed at the two ends of the rotary shaft respectively; a worm gear is installed at the position, in the power shell, of the rotary shaft; supporting leg frames are installed on the two sides of the bottom of each supporting plate respectively; a fan is installed on one side in each supporting leg frame; and an aeration plate is installed on the inner wall of each supporting leg frame at the air outlet end of the corresponding fan. The microporous aeration and oxygenation device increases the dissolving rate of oxygen and water, also enlarges an oxygenation range of an oxygenation device and prevents the oxygenation device from being blocked.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to a microporous aeration and oxygenation device for aquaculture. Background technique [0002] With the continuous development of the economy, people's quality of life has been further improved, and many people's demand for aquatic products is also increasing, resulting in relatively high breeding densities across the country, and a large number of breeding organisms will consume a lot of water. Oxygen causes hypoxia in aquaculture water, and the result is that the aquaculture organisms are prone to illness and even death. In addition, there will inevitably be excess organic matter in the aquaculture water body. The dissolved oxygen in the aquaculture water is consumed, so that the dissolved oxygen content in the aquaculture water is lower than the aquaculture standard. Therefore, in the current aquaculture industry, an aeration and oxygenation device is required to a...

[0002] With the continuous development of the economy, people's quality of life has been further improved, and many people's demand for aquatic products is also increasing, resulting in relatively high breeding densities across the country, and a large number of breeding organisms will consume a lot of water. Oxygen causes hypoxia in aquaculture water, and the result is that the aquaculture organisms are prone to illness and even death. In addition, there will inevitably be excess organic matter in the aquaculture water body. The dissolved oxygen in the aquaculture water is consumed, so that the dissolved oxygen content in the aquaculture water is lower than the aquaculture standard. Therefore, in the current aquaculture industry, an aeration and oxygenation device is required to aerate the water body regularly or irregularly. The general aeration and oxygenation device is expensive, and the installation and maintenance are more complicated, the oxygenation capacity and dissolution rate are low, and some aeration and oxygenation devices are fixed in a specific position for oxygenation. In terms of aquaculture, it is impossible to achieve the purpose of increasing oxygen in a large area. Some aeration devices are even suspended on the water or placed on the bottom of the water. Not only the aeration effect is not good, but also the upper and lower water bodies cannot be exchanged. Blockage phenomenon
