Aerator

Abstract

The invention discloses an oxygen enrichment device which comprises a fan (1), a pump box (2), an air inlet pipe (3) and an air floating barrel (4), wherein a position adjuster (9) is arranged at the lower end of the air floating barrel (4); the bottom of the air inlet pipe (3) is connected with a plurality of micropore aeration devices (5); a rotating shaft (11) is arranged at the lower end of the fan (1); a supporting rod (12) is arranged at the lower end of the rotating shaft (11); cleaning brushes (13) are arranged on the supporting rod (12); a telescopic sleeve (7) is also arranged at the lower end of the pump box (2). The assemblies such as aeration devices, the cleaning brushes and the telescopic sleeve are additionally arranged on the oxygen enrichment device, so that the oxygen dissolving amount in water can be increased due to a large quantity of formed micro air bubbles, and suspensions in the water can be separated away and collected; the depth of an oxygen enrichment water domain can be adjusted; the water circulation efficiency is improved, growth and multiplication of planktons are promoted, and the fish carrying capacity of the water is improved; the oxygen enrichment device is novel in structure, convenient to operate and wide in application range.

Description

technical field [0001] The invention relates to the technical field of aquaculture aeration, in particular to an aerator. Background technique [0002] At present, the aerators used in aquaculture include impeller type, water wheel type, water spray type and air pump type. The impeller type and water spray type aerators can only stir the water on the surface and increase the dissolved oxygen on the water surface. It is difficult to improve the dissolved oxygen in deeper water; the pump type can stir the water at a certain depth, but the pressure at the water outlet is too high, which will cause damage to the fish; It is clogged and costly, and it is laborious to clean; in traditional water aquaculture, surface water is exposed to air, algae photosynthesis, etc., making it saturated with oxygen, and the temperature is high, while the temperature of the bottom water is almost oxygen-free. If the surface water And the bottom water cannot be replaced and renewed by circulation,...

[0002] At present, the aerators used in aquaculture include impeller type, water wheel type, water spray type and air pump type. The impeller type and water spray type aerators can only stir the water on the surface and increase the dissolved oxygen on the water surface. It is difficult to improve the dissolved oxygen in deeper water; the pump type can stir the water at a certain depth, but the pressure at the water outlet is too high, which will cause damage to the fish; It is clogged and costly, and it is laborious to clean; in traditional water aquaculture, surface water is exposed to air, algae photosynthesis, etc., making it saturated with oxygen and high temperature, while the bottom water temperature is almost oxygen-free. If the surface water And the bottom water cannot be replaced and renewed in a cycle, and the residual feed, fish excrement and other pollutants are stored and accumulated in the pond, the water quality continues to deteriorate, the ecological chain is broken, and a vicious circle is formed, the growth capacity of the water body is reduced, and large fish diseases are prone to outbreaks , unhealthy and efficient farming of commercial fish
