Abstract

The utility model discloses a convection aerator device for fish ponds, composed of an oxygenation pump, a water division head, an air exhausting panel and an aqueduct. The utility model can keep sufficient oxygen content in the fish pond and prompt the air directly ascend to the water surface so that the water in the fish pond can aggregatively flow in a short time and form the convection, which can avoid the partial oxygen-containing saturation and anoxic zones in the pond. The utility model has the advantages of simple structure, and low cost, and is useful for raising substantially the survival rate of the fish in the sea-water and the freshwater fish pond.

Description

The fish pond convective oxygenation apparatus

The utility model belongs to the breed instrument in seawater, the freshwater aquaculture industry, particularly a kind of convective oxygenation apparatus that is used for the fresh water fish pond.

Seawater encloses pond and freshwater and breeds fish and can improve the output of unit are, create considerable economic, but owing to do not flow in the pond, the density of in addition breeding fish is big, can cause anoxic in the pond, therefore have only the suitable aeration device of employing that the breeding environment in fish pond is significantly improved, oxygenation apparatus power consumption height in the existing technology, and can not use continuously, and in the pond, form easily and locally hold that oxygen is full to be closed and the anoxic zone, a kind ofly can make whole fish pond form even mixed flow current, and can keep the convection current oxygenation apparatus of q.s oxygen not to be reported so far.

The purpose of this utility model is a kind of fish pond convection current aeration device that provides in order to overcome above-mentioned shortcoming.

Implementation of the present utility model is:

It is one by water guide part, water diversing head partly, the device that suction part and wooden tripod are formed, during use, only need this device is fixed in the fish pond, starting oxygen charging pump squeezes into air in the appendix, gas just can air jet pipe and diffusing gas plate, aqueduct in installing be diffused in the pond, thereby realizes the task that the utility model proposed.

The utility model has the advantages that owing to reach loose gas plate and air jet pipe by being placed with an aqueduct above the device at it, thereby can guarantee that the gas in the oxygenation process directly rises to the pond water surface site, make whole pond water can very fast gathering, flowing forms convection current, water is difficult for forming full the closing and the anoxic zone of local appearance oxygen in the pond, thereby make the fish pond maintain sufficient oxygen content, thereby can increase substantially the survival rate of fish.

The utility model is provided by following examples:

Below in conjunction with accompanying drawing the utility model is described further.

Accompanying drawing: fish pond convective oxygenation apparatus structural representation.

Among the figure: pin tripod 1, oxygen charging pump 2, appendix 3, air guide cap 4, diffusing gas plate 5, water diversing head 6, aqueduct 7, air jet pipe 9, bottom pin 10.

This device is to cross four mutually perpendicular aqueducts 7 in the upper part of hollow water diversing head 6, there is a diffusing gas plate 5 parallel each other with aqueduct on the last top of hollow water diversing head, this plate end positions place has several diffusing gas apertures, there is a circular air jet pipe 9 that has aperture at following position in water diversing head, this pipe is hung in above the water diversing head with rope system, on the water diversing head that assembles is fixed at the bottom of the pond, fish pond by the bottom pin 10 that is installed in the water diversing head lower end, oxygen charging pump 2 is fixed on the item position, end of pin tripod 1, join by appendix 3 and air jet pipe 9 then, only need during use this device is immersed in the water, start oxygen charging pump 2 gases and just enter air jet pipe 9 and diffusing gas plate 5 through appendix 3, be input in the pond water, the effect of aqueduct 7 is that the air in the dispersing water increases the oxygen content in the pond, therefore should adopt larger-diameter polytetrafluoroethyltubing tubing during fabrication, its diameter generally is advisable at 10-15 centimeters.

The material of diffusing gas plate 5, water diversing head 6 is made for polytetrafluoroethylplastic plastic tubing.

Claims

1, a kind of convection current oxygenation apparatus that is used for fresh water fishpond cultivation; Form by hollow water diversing head 6 and oxygen charging pump 2; Four mutually perpendicular aqueducts 7 have been crossed in the upper part that it is characterized in that described hollow water diversing head 6, the last top of hollow water diversing head has one to have several diffusing gas apertures with the parallel each other diffusing gas plate 5 of aqueduct, at its two ends, position, following position in water diversing head also has a circular air jet pipe 9 that has several apertures, and this pipe is hung in above the water diversing head by system with rope; Top bit at pin tripod 1 has an appendix 3, connects with oxygen charging pump 2, air jet pipe 9.

2, convection current oxygenation apparatus in fish pond according to claim 1; It is characterized in that diffusing gas plate, the water diversing head in the convection current oxygenation apparatus, the material of aqueduct are that polytetrafluoroethylene (PTFE) is made.
