Description

Technical Field

[0001] The utility model relates to the field of aquaculture alkalinity regulation, in particular to a total alkalinity regulating device for mandarin fish breeding. Background Art

[0002] Aquaculture has certain requirements for the total alkalinity of water bodies. The total alkalinity of water bodies refers to the sum of alkaline substances in water bodies, mainly carbonates and bicarbonates. If the total alkalinity of water bodies is relatively low and insufficient carbonates and bicarbonates are provided, the bound alkaline substances in the water bodies will be released, and the alkalinity of the water bodies will increase, which will lead to unstable water bodies. Unstable water bodies will lose the balance of bacteria and algae, which may cause water changes. Therefore, it is particularly important to maintain the total alkalinity of water bodies.

[0003] A patent document in China with application number 201510124990.4 and publication date of July 1, 2015 discloses a device for adjusting pH value for turtle farming in a greenhouse, including a breeding pool, a storage box, a motor base, a pH tester, a bearing, a rotating base, an air pump, a discharge pipe, a motor, and a flow controller. The pH value of the water in the breeding pool is detected by the pH detector, and the pH tester feeds back the detected information to the air pump and the flow controller. The air pump and the motor are powered on to pump out lime powder from the center of the storage box, and the flow controller is controlled according to the acidity in the breeding pool. The flow controller controls the amount of lime powder discharged, and the rotating base is driven by the motor to rotate, and the lime powder is sprayed from the discharge pipe into the breeding pool, thereby adjusting the pH value in the breeding pool.

[0004] The regulating device cannot detect the total alkalinity of the water body. At the same time, it directly sprays lime powder into the breeding pool. The lime powder is directly mixed with the pool water in the breeding pool. The mixing uniformity of the lime powder and the pool water is poor. At the same time, the lime powder releases heat when in contact with the pool water, which will cause the temperature of the pool water to rise, thereby affecting the cultured animals.
