In aquatic animal sapling multiplication base, for sufficient dissolved oxygen is arranged in the water body, each fry chamber all is equipped with the blower more than 2, day and night gives the inflation of fry chamber incessantly.Blower pressurized air order about air through pipeline transmission at the bottom of the larval rearing water, gas is risen at the bottom of the pond becoming continual bubble through gas stone at the bottom of the pond, reaches the purpose that increases dissolved oxygen, also is through with to the utilization of air-flow simultaneously.
The purpose of this utility model is to provide a kind of and can makes full use of air-flow to make it become a kind of be the water pump of power with the air-flow.
The aerodynamic force water pump is provided with base, tracheae, gas stone and conduit, and tracheae is located on the base; The air outlet of tracheae connects gas stone, and the lower end of conduit is located on the base and is established water intake, and gas stone places in the conduit.Or/and water outlet can be established filtering layer, be used for collection of debris, fertilized egg, food organisms etc. at the water intake of conduit, for example adopt the filtering layer of bolting silk layer, adopt the filtering layer of bolting silk bag as the conduit water outlet as the water injection through pipe mouth.
When the utility model being applied to aquatic animal sapling multiplication place, at the bottom of it is positioned over larval rearing water, when gas when the water surface is poured at the bottom, water body around must driving produces and stirs, if gas is confined in the narrow space, water body around the stirring that the gas rising is produced will force forms directive flowing, thereby reaches the purpose of pump water.The height of pump water can reach 10~20cm.Obviously, this aerodynamic force water pump can increase the dissolved oxygen of breeding water body; Can be in same seedling pond equidirectionally put several aerodynamic force water pumps, then can reach the purpose of ordering about full pond water body directional flow, this cultivation for kind of fish is especially crucial; If the bolting silk layer of different size or bag just can reach the purpose of collecting organic debris, fertilized egg, food organisms etc. on water inlet and water outlet mouth mask.
The advantage of this aerodynamic force water pump is: 1, simple in structure, and be easy to assembling, use, not fragile, cost is low; 2, need not extra motor and power supply, do not have danger, expense is low; 3, it is abundant and flow that the water body in the filtering layer contains oxygen, and the biology in the filtering layer can because of anoxic or to drain the refuse excessive concentration dead; When 4, collecting fertilized egg, food organisms, light and slow because of collecting current, so to almost not damage of biology; 5, the intensity of pump water can realize by the size that changes air-flow.
As seen from Figure 1, the aerodynamic force water pump is made up of base 1, tracheae 2, gas stone 3, conduit 4, water intake bolting silk layer 5 and water outlet bolting silk bag 6.Tracheae 2 is located on the base 1, and the air outlet of tracheae 2 connects gas stone 3.The lower end of conduit 4 is located on the base, establishes water intake bolting silk layer 5 at the water inlet of conduit 4, sets out mouth of a river bolting silk bag 6 at water outlet.
