Problems solved by technology

[0003] In the fry cultivation stage, the water depth of the fry cultivation pond is generally less than 0.7 meters, and the area is within 0.6 mu; if a traditional aerator or aeration pump is used, a large amount of energy will be consumed, such as electric energy, fuel oil, etc., and the breeding cost will increase. greatly increase

Embodiment 1

[0034] Please refer to Figure 1 to Figure 5 , the present embodiment provides an aerator, which includes a mounting frame 100, a stirring device 110, a rotating shaft 120 and multiple groups of windward components, and multiple groups of windward components are evenly distributed along the circumference of the rotating shaft 120, and the windward components and the stirring device 110 pass through The rotating shaft 120 is connected; the rotating shaft 120 is rotatably installed on the installation frame 100 .

[0035] In this embodiment, the mounting frame 100 is made of stainless steel, because the mounting frame 100 needs to be made of corrosion-resistant materials because it is fixed in water for a long time. However, stainless steel has the characteristics of corrosion resistance and easy processing. The shape of the entire installation frame 100 is the same as the stool seen in daily life, with four legs and a circular plate above the four legs, and a through rotation ...

Embodiment 2

[0040] Please refer to Figure 1 to Figure 5 , this embodiment proposes based on the technical solution of Embodiment 1: the windward assembly includes a plurality of windward tubes 150 with air inlets and air outlets, the air inlets are larger than the air outlets, and the orthographic projection directions of the windward assemblies partially overlap.

[0041] In this embodiment, the windward component can also be composed of six windward tubes 150, the diameter of the air inlets of these six windward tubes 150 is larger than the diameter of the air outlet, so that more air volume can enter, and the flow velocity of the wind outlet can be increased. with greater impetus. These six windward cylinders 150 are evenly distributed along the circumference of the rotating shaft 120, forming a ring shape, that is, the air outlet part of the first windward cylinder 150 extends to the air inlet of the second windward cylinder 150; the air outlet part of the second windward cylinder 15...

Embodiment 3

[0044] Please refer to Figure 1 to Figure 5 , this embodiment proposes based on the technical solution of Embodiment 1: the stirring device 110 includes a volute 111 and a plurality of agitating blades 112 arranged in the volute 111 , and the plurality of agitating blades 112 are evenly distributed along the circumference of the rotating shaft 120 .

[0045] In this embodiment, the stirring device 110 further includes a volute 111 and five stirring blades 112 disposed in the volute 111 , the five stirring blades 112 are evenly distributed along the circumference of the rotating shaft 120 , and the volute 111 is provided with an outlet. Due to the small internal space of the volute 111, combined with the special shape of the volute 111, when the rotating shaft 120 drives the stirring blade 112 to rotate, the path of the water flow in the volute 111 is increased, and the water is pushed out toward the outlet, and the water flows from the volute. The outlets on the shell 111 are...

Abstract

The invention provides an aerator, and relates to the technical field of aquaculture equipment. The device comprises a mounting frame, a stirring device, a rotating shaft and a plurality of windward assemblies, the windward assemblies are uniformly distributed in the circumferential direction of the rotating shaft, and the windward assemblies are connected with the stirring device through the rotating shaft; and the rotating shaft is rotationally mounted on the mounting frame. According to the aerator provided by the invention, wind energy of the nature is used as driving force, and the stirring device is driven to rotate in water through the windward assembly, so that convection exchange of water is promoted, the water quality condition is improved, and the oxygen content in water is increased. The whole structure is simple, and daily maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to an aerator. Background technique [0002] The aerator is a machine that is often used in fish farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the living environment of the fish. Traditional aerators generally rely on electric motors or diesel engines as power sources to drive air pumps to drive air into the water, so that the "oxygen" in the air can be quickly transferred to the aquaculture water body, so as to achieve the purpose of increasing the oxygen content in the water. [0003] In the fry cultivation stage, the water depth of the fry cultivation pond is generally less than 0.7 meters, and the area is within 0.6 mu; if a traditio...
