Selection of oxygenation equipment for shrimp fry farming: Reasonable combination of Roots blower and explosive oxygen disc
In shrimp aquaculture, it is crucial to properly match the Roots blower and explosive oxygen tray (usually referred to as the oxygenation tray) in order to effectively increase oxygen production. The following are recommendations for the combination of Roots blowers and aerators based on the actual situation of aquaculture:
1、 Selection of Roots blower
1. Model and specifications:
Select the appropriate Roots blower model based on the aquaculture area and water depth. For example, for larger aquaculture areas or deeper water bodies, Roots blowers with larger diameters and higher power can be selected.
Common models of Roots blowers include SR50-350 and Three Leaf Roots blowers, which have characteristics such as energy efficiency and stability.
2. Power and Flow:
The higher the power and flow rate, the better the oxygenation effect is usually. But we also need to consider energy consumption and cost, and choose economically reasonable power and flow.
For shrimp fry aquaculture, it is recommended to calculate the power and flow rate of the Roots blower based on the aquaculture density and oxygen demand.
3. Quality and Service:
Choose Roots blowers with reliable quality and service. For example, priority can be given to those with a good reputation and credibility in the market.
Ensure that the fan is stable and reliable during operation, and can provide a continuous and stable oxygen supply.
2、 Configuration of oxygenation disk
1. Installation method:
You can choose between disc installation method or strip installation method. The disc installation method is to fix the oxygenation disc at the bottom of the pool, with a distance of 10-15 centimeters from the bottom of the pool. The strip installation method is to fix the exposure pipe at intervals at the bottom of the pool.
Determine the number and location of aerators based on the layout and breeding density of the aquaculture pond. Ensure that the aerators are evenly distributed throughout the entire breeding area to achieve the desired oxygenation effect.
2. Material and Structure:
Oxygen plates are usually made of corrosion-resistant and wear-resistant materials to ensure that they are not easily damaged during long-term use.
Structurally, the aerator should have a good aeration effect, capable of generating a large number of tiny bubbles and increasing the dissolved oxygen in the water.
3. Maintenance and upkeep:
Regularly check the operation of the oxygenation disc to ensure its normal functioning. If blockage or damage is found, it should be cleaned or replaced in a timely manner.
Regularly maintain the Roots blower and aerator, including changing lubricating oil, cleaning the inside of the blower, etc., to extend the service life of the equipment.
3、 Matching suggestions
1. Determine configuration based on breeding needs:
When determining the configuration of Roots blowers and aerators, factors such as breeding species, breeding density, water quality conditions, and the specific needs of breeders should be fully considered.
For example, for high-density aquaculture or ponds with poor water quality, the power of Roots blowers and the number of aerators can be appropriately increased.
2. Optimize layout and installation:
Reasonably plan the layout and installation location of Roots blowers and aerators to reduce energy consumption and improve oxygenation efficiency.
For example, Roots blowers can be installed near the breeding area to reduce energy loss during pipeline transportation.
3. Equipped with monitoring and control equipment:
It is recommended to equip dissolved oxygen monitoring equipment to monitor real-time changes in dissolved oxygen levels in water bodies.
According to the changes in dissolved oxygen content, flexibly adjust the working time and operating parameters of the Roots blower and aerator disk to achieve the desired oxygenation effect and economic benefits.
In summary, when aerating shrimp fry aquaculture, it is necessary to reasonably match Roots blowers and aerators. By selecting appropriate models and specifications, optimizing layout and installation, and equipping monitoring and control equipment, measures can be taken to ensure sufficient and stable dissolved oxygen in the aquaculture water, providing good environmental conditions for the growth of shrimp seedlings.
