A device for pushing water and increasing oxygen in a culture pond

Abstract

The invention relates to a water pushing oxygenation device of a culture pond. An output shaft of a submersible motor is coaxially connected with an air flotation shaft, the front end of the air flotation shaft is connected with an air flotation device in an air flotation cover, the outer wall of the air flotation cover is communicated with an air pipe, and the air pipe upwards penetrates a diversion barrel and extends to space above water; the submersible motor is connected with an input end of a speed reduction box, an output end of the speed reduction box is assembled with a propeller shaftthrough a three-stage gear in a meshed manner, the propeller shaft and the air flotation shaft are coaxially arranged outside the air flotation shaft in a sleeved manner, and a propeller is fixed onthe propeller shaft and positioned in rear of the air flotation cover; only the front end of the diversion barrel is open, and the diversion barrel wraps the air flotation cover and the propeller in space surrounded by the diversion barrel. An aeration device is not needed, so that blockage of an aeration hole is avoided, and maintenance work and cost are reduced; the water pushing oxygenation device is uniform in water pushing flow speed and good in adjusting performance; the air flotation cover utilizes negative pressure to suck air in, so that airflow stability is high, and adjustability ishigh.

Description

technical field [0001] The invention relates to an aeration device for pushing water and increasing oxygen, and belongs to the technical field of pushing water and increasing oxygen for breeding ponds. Background technique [0002] Pond farming has become the main form of aquaculture and the main source of aquatic product supply in China. China's aquaculture is developing rapidly towards high density and intensification. More and more aquaculture wastes are accumulated in the aquaculture environment, causing the aquaculture environment to deteriorate. However, China has not yet established aquaculture wastewater discharge standards, and a large amount of aquaculture wastewater is discharged into the surrounding environment. It also puts a lot of pressure on the surrounding environment of the breeding. In addition, due to the low level of industrial development, the degree of facilities for pond aquaculture is very low. Most aquaculture ponds have problems such as dilapidate...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is: in the existing pond culture, the device that can realize the function of pushing water and increasing oxygen at the same time is generally an aeration device, and if the aeration and oxygen increasing device is used for a long time, some algae will grow on the surface of the aeration tube , forming biofouling to block the aeration holes, after blocking, it should be cleaned regularly, and the maintenance cost is high
