1、 Definition and purpose
Aquaculture oxygenation tray, also known as aeration tray, is a device that releases small bubbles through micropores to evenly disperse oxygen from the air into the water. It is mainly used in aquaculture ponds, fish boxes, fish ponds and other water bodies to increase the oxygen content in the water, improve water quality, and promote the growth of aquatic organisms.
2、 Working principle
The working principle of the oxygenation disc is mainly based on the air compressor or three blade Roots blower fan compressing the air and sending it into the oxygenation disc. There are a large number of tiny holes inside the oxygenation disc, and air is released from these holes, forming a large number of fine bubbles. These bubbles rise very slowly in water and have a significant effect on dissolving oxygen, thereby greatly increasing the oxygen content in the water.
3、 Structure and Type
Structure: Oxygenation discs are usually made of materials such as plastic or stainless steel, with small holes covering the surface for spraying small bubbles. It has one or more air ducts inside for delivering compressed air to small holes.
Type: Depending on the shape and installation method, oxygenation discs can be divided into various types such as disc type, strip type, etc. Disc aerators are usually used for smaller bodies of water, such as fish boxes, ponds, etc; The strip type aerator is suitable for larger water bodies, such as aquaculture ponds.
4、 Installation and use
Installation: The installation of the oxygenation disc needs to be carried out according to the actual situation of the water body. Generally speaking, a frame can be made of materials such as steel bars or stainless steel, and the oxygenation disc can be fixed on the frame, and then connected to a gas duct and an oxygen source (such as an oxygen cylinder or air compressor). During installation, it is necessary to pay attention to the placement of the aerator disc to ensure the aeration effect. For larger water bodies such as ponds, the disc or strip installation method can be used to evenly distribute the aerator disc at the bottom of the pond or in the water body.
Usage: Determine the time and period for starting up and increasing oxygen based on the pattern of dissolved oxygen changes in the water body. Generally speaking, during low oxygen periods such as rainy weather or nighttime, it is necessary to increase the startup time appropriately. At the same time, it is necessary to regularly clean the oxygenation tray to prevent blockage and contamination.
5、 Advantages and Characteristics
Improving water quality: Oxygen plates can significantly increase the oxygen content in water bodies, improve water quality and environment, and provide better growth conditions for aquatic organisms.
Promoting growth: Adequate oxygen helps with the metabolism and growth of aquatic organisms, improving aquaculture yield and quality.
Energy saving and environmental protection: Compared with traditional oxygenation methods, oxygenation discs have higher energy efficiency and lower energy consumption, while reducing noise and pollutant emissions.
Easy to maintain: The aerator disk has a simple structure, is easy to clean and maintain, and reduces breeding costs.
6、 Precautions
When using an aerator, attention should be paid to safe use of electricity and fire prevention measures.
Regularly clean and maintain the oxygenation disc to prevent blockage and contamination.
Reasonably adjust the start-up time and time period of the aerator according to the actual situation of the water body and the needs of aquaculture.
In summary, aquaculture aerators are efficient, energy-saving, and environmentally friendly aerators, which are of great significance for improving water quality, promoting the growth and reproduction of aquatic organisms. Widely used in aquaculture, it provides strong support for the sustainable development of the breeding industry.
