Novel submersible type aerator
Technical field:
The utility model relates to aquaculture field, is specifically related to a kind of novel submersible type aerator.
Background technology:
Sufficient dissolved oxygen is the essential condition that pond culture realizes stable and high yields.The use of aerator can increase the dissolved oxygen in the water, improves water quality, improves the primary productivity in the water body, and then realize volume increase.The aerator that present China uses in pond culture mainly contains vane type, Waterwheel-type, jetting type etc., and it is bigger that Chi Shui stirs the spray that forms, and effective area is little, and is low to pond bottom oxygen-transfer efficiency.The limitation that emerging micropore aerator exists installation, dismounting, uses, though improved the oxygenation effect of water body, the circulation of bottom water body, exchange are limited.
The utility model content:
The purpose of this utility model provides a kind of novel submersible type aerator, and equipment is small and exquisite, and utilization flexibly, and is easy for installation.It adopts the combination of hydraulic principle, improve the dissolved oxygen content of cultivating pool bottom water body, active area is big, circulating water flow does not have the dead angle, effectively suppressed growing in a large number of pond bottom anaerobic bacteria, improve pond water quality, bottom environment, reduced the disease generation of dwelling and culturing kind at the bottom of the pond, improved survival rate.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises submersible motor 1, air tank 2, sealing ring 3, whirligig 4, power line 5, external tracheae 6, metallic support 7; Submersible motor 1 is fixed in the top of metallic support 7, and its upper end is connected with power line 5, and air tank 2 is arranged on the lower end of submersible motor 1, and air tank 2 lower ends are provided with whirligig 4, air tank 2 is provided with sealing ring 3 with the junction of whirligig 4, and an end of external tracheae 6 is connected in air tank 2.
The utlity model has following beneficial effect: the dissolved oxygen content that can improve cultivating pool bottom water body, active area is big, circulating water flow does not have the dead angle, thereby suppressed growing in a large number of pond bottom anaerobic bacteria, pond water quality, bottom environment have been improved, reduce the disease generation of dwelling and culturing kind at the bottom of the pond, improve survival rate.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises submersible motor 1, air tank 2, sealing ring 3, whirligig 4, power line 5, external tracheae 6, metallic support 7; Submersible motor 1 is fixed in the top of metallic support 7, and its upper end is connected with power line 5, and air tank 2 is arranged on the lower end of submersible motor 1, and air tank 2 lower ends are provided with whirligig 4, air tank 2 is provided with sealing ring 3 with the junction of whirligig 4, and an end of external tracheae 6 is connected in air tank 2.
Described whirligig 4 is an impeller.
Described metallic support 7 is a triangle, is provided with securing member 7-1 between per two supports.
This embodiment adopts the combination of hydraulic principle, by the hydraulic part of uniqueness, and emanant water, gas hybrid channel, air is imported the pond bottom, and under the effect of centrifugal force and impeller cutting, current are powerful, the air bubble that forms is tiny, intensive, and is big with the contact area of water body.Stir up and down by the bubbles entrain water body that rises, take the oxygen of algae generation in the water body of upper strata and the oxygen in the atmosphere to pond bottom; Along with the rotation of impeller, driven the rotation of bottom current simultaneously, operating radius reaches 30~40 meters, has effectively increased the circulation and the gas exchange of bottom water body, has improved oxygenation effect and active area to pond bottom water body.
This embodiment can improve the dissolved oxygen content of cultivating pool bottom water body, and active area is big, and water circulation does not have the dead angle, thereby suppressed growing in a large number of pond bottom anaerobic bacteria, improve pond water quality, bottom environment, reduced the disease generation of dwelling and culturing kind at the bottom of the pond, improved survival rate.
