Microbubble aerator for fish and shrimp ponds

Abstract

The invention relates to a microbubble aerator for fish and shrimp ponds, which is composed of a cabinet 12, a gas-water mixer 2, a gas-water outlet pipe 1, a sinking pump 11 and a pump-outlet pipe 10, wherein the cabinet 12 is a cylinder; the sinking pump 11 is positioned on the bottom in the cabinet 12; the pump-outlet pipe 10 is connected to the gas-water mixer 2; the gas-water mixer 2 is externally connected with the gas-water outlet pipe 1; the gas-water mixer 2 is provided with a gas inlet pipe 5; the lower end of the gas inlet pipe 5 is communicated with the inside of the gas-water mixer 2; and an internal water pipe 4 is arranged in the gas-water mixer and provided with a strong magnet 7 and a weak magnet 8. The invention has the advantages of simple structure, low production cost and energy conservation, and is a microbubble aerator for fish and shrimp ponds; the aeration quantity can be regulated according to the water quality status, and the dissolved oxygen is 8-9.2 mg / L; the bubble size can reach 20-30 micrometers, and the bubbles can not be diluted by the air in water within 20-50 seconds; and the aerator has the function of air flotation, and is convenient for removing impurities in water and keeping the water clear.

Description

Technical field: [0001] The invention belongs to high-density aquaculture water treatment technology, and is a microbubble aerator in a fish and shrimp pond: Background technique: [0002] Before the present invention was made, the method for dissolving oxygen in the ponds of domestic farms mainly relied on waterwheel type aerators and nano waterfall tube aeration to increase oxygen. Waterwheel type aerator (such as YC-1.5 aerator produced by Jinhu Huaneng Electromechanical Co., Ltd.) mainly relies on the motor to drive the plastic blades to roll in the water to increase the oxygen in the water. This aeration method has low aeration effect. , The dissolved oxygen effect is poor, and the motor power consumption is large, and it is prone to failure, uneven oxygenation, low dissolved oxygen at the bottom of the water body, and boiling water on the surface, which has an adverse effect on the growth of high-density aquaculture fish and shrimp; nano-cascade aeration and oxygenation Me...

AI Technical Summary

Problems solved by technology

This kind of breeding system mainly relies on air bubbles to increase oxygen in the water, which can make the oxygen content in the water reach 6 milliliters, but the oxygen injected into the water is quickly absorbed by the air, the oxygen utilization rate is low, the cost is high, and the construction is relatively complicated. It is relatively difficult to maintain, and it is not suitable for the current situation of domestic breeding

[0004] Micro-bubble equipment oxygenation device is also useful abroad, such as the micro-bubble equipment oxygenation device developed by the University of Tokyo in Japan, the motor uses 1.5KW, and the area of ​​aquaculture water is only 500m 3 .It uses the principle of high-pressure water pump and jet flow, but the bubbles are relatively large, it is difficult to separate the fine oil and suspended solids in the water, the oxygen content in the water is not balanced, and the jet tube must be cleaned regularly manually
