Aquaculture water area temperature increasing and oxygenating device

Abstract

The invention discloses an aquaculture water area temperature increasing and oxygenating device which comprises a water pump. The water pump is connected with a temperature increasing device which comprises a cylinder water storage box. A cylinder rotor is arranged in the cylinder water storage box. Column holes are formed in the side face of the cylinder rotor. The axis of each column hole is perpendicular to the axis of the cylinder rotor. A water inlet and an air inlet are formed in the side face of the bottom of the cylinder water storage box. The water inlet is connected with the water pump. The air inlet is connected with an air pump. A water outlet is formed in the side face of the top of the cylinder water storage box. A motor is connected to the cylinder rotor. According to the technical scheme, the aquaculture water area temperature increasing and oxygenating device is compact in structure, easy to operate and capable of increasing water temperature of an aquaculture water area fast and increasing the oxygen content of water in the water area; time for culturing freshwater shrimps is prolonged to a certain degree, the culture yield is increased, and requirements of people for the daily freshwater shrimps are met.

Description

technical field [0001] The invention relates to an aquaculture water area temperature raising and oxygenation device for increasing the temperature and oxygen content of aquaculture water in aquaculture. Background technique [0002] Green shrimp is delicious and nutritious. It is a high-quality aquatic product with high protein, low fat and high energy. It has been welcomed by consumers for a long time. With the improvement of people's living standards, the demand for freshwater shrimp is also gradually increasing, but the raising of freshwater shrimp has extremely high requirements on the environment and temperature. During spawning and hatching of broodstock, the optimum temperature is 26-28°C. During the larval cultivation period, the optimum temperature is 28-29°C in the early stage, 30-32°C in the later stage, and 20-30°C for adult growth. When the water temperature drops below 14°C, it enters the overwintering period. Therefore, when the temperature drops in winter ...

AI Technical Summary

Problems solved by technology

Therefore, when the temperature drops in winter or even late autumn, the cultivation of freshwater shrimp cannot be carried out, which greatly reduces the production of freshwater shrimp, and winter is the period when the price of real goods rises, which greatly reduces the income of farmers.

In the prior art, the cultivation of freshwater shrimp mostly adopts the method of indoor heat preservation to prolong the cultivation time. This cultivation method is costly and is not conducive to quickly controlling the temperature of the cultivation area.
