Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a dissolved oxygen enrichment system for aquaculture. Background Art

[0002] In aquaculture, dissolved oxygen has the following specific functions: dissolved oxygen can provide the oxygen necessary for the life activities of farmed animals; dissolved oxygen can be beneficial to the growth and reproduction of aerobic microorganisms to promote the degradation of organic matter; dissolved oxygen can reduce toxic and harmful substances in water; dissolved oxygen can inhibit the activity of harmful anaerobic microorganisms; dissolved oxygen can enhance the immunity of farmed animals.

[0003] However, most existing dissolved oxygen aeration equipment directly supplies oxygen into the aquaculture water. That is, if the oxygen dissolution efficiency is low, part of the oxygen will leave the aquaculture water before dissolving, which will lead to a waste of oxygen resources. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model provides a dissolved oxygen enrichment system for aquaculture, which can be conducive to fully dissolving oxygen.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0014] In one embodiment, the premixing tank is provided with a liquid level sensor electrically connected to the controller.

[0015] The beneficial effects of adopting the above technical solution are: the liquid level sensor can monitor the liquid level in the premix tank so as to stop supplying oxygen and water when the liquid level is too high, and also facilitate supplying oxygen and water when the liquid level is too low.

[0017] The beneficial effects of adopting the above technical solution are: the check valve can prevent water and oxygen in the premixer from flowing back to the variable frequency water pump; the flexible joint can absorb the displacement generated during the operation of the premixer water inlet pipeline.

[0018] In one embodiment, the oxygen generating device includes a liquid oxygen tank and a vaporizer, and the outlet end of the liquid oxygen tank is connected to the vaporizer and the oxygen pressure regulating tank in sequence.
