Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture, and particularly relates to an oxygenation equipment for aquaculture. BACKGROUND

[0002] The main function of the oxygenation machine is to increase the oxygen content in water to ensure that the fish in the water will not be short of oxygen, and also to inhibit the growth of anaerobic bacteria in the water to prevent the deterioration of the water and threaten the living environment of the fish. The oxygenation machine generally blows air into the water by means of its air pump to achieve the purpose of increasing the oxygen content in the water.

[0003] The patent with the patent publication number CN108293947A discloses an oxygenation equipment for aquaculture, which comprises an equipment shell, a driving device, a propeller, an air inlet device, an air inlet pipe, a water jet pipe and a floating body. The equipment shell comprises an upper shell section and a lower shell section. The upper shell section is closed at the top and the cross-sectional curve is a straight line. The lower shell section is open at the bottom and the cross-sectional curve is an involute curve. The water enters the oxygenation equipment from the bottom of the lower shell section. The oxygenation equipment promotes the rapid and efficient work of the oxygen bacteria in the water, accelerates the decomposition of the organic matter in the water, and fully decomposes the animal excrement and excess feed generated in the aquaculture.
