Principle of work and methods for using them of the present invention:
The present invention adopts three-dimensional the installation, is fixed on the stand at the bottom of the prawn fishing breeding pond pond by stiffening plate 9, and the submergence water level is about 2/3 place of the present invention's height, and water level is too high or too low all can to influence the foam separation effect; The level of oxygenation 11 is stretched out direction and should be become parallel placement with pond dike wall.
The present invention includes foam separation and oxygenation two portions, is to be the equipment of one with foam separation part and oxygenation segment set double effects.
The foam separation part is by air suction pipe 1, valve A5, ejector A6, inlet pipe A8, bubble decollator 7; With compositions such as water pump 3, water-in 4, foam mixing chamber 14, dirt collecting chamber 16, sewage draining exit 17 and water outlets 20.When jet-pump and water pump 3 are started working, current by ejector A6 through inlet pipe A8, utilize the jet current principle of Venturi ejector, ambient air is sucked continuously by air suction pipe 1, air is regulated the air input size by valve A5, be transported to bubble decollator 7, and fully and equably disperse by gas distributor 7, produce a large amount of micro-bubbles, enter in the foam mixing chamber 14, at this moment water pump 3 enters the water of foam mixing chamber 14 through water inlet pipe 4, with in foam mixing chamber 14 in the micro-bubble thorough mixing, these micro-bubbles can planar water in the process of come-up in suspended substance and dissolved organic matter, this moment, foam mixing chamber 14 was full of the mixture of a large amount of foams and water, and overflow from foam spillway 18, combine in the contaminants collector 16, at this moment, should open regulated valve A5, the formation speed of suitable adjusting and control foam, generate abundant up to foam, stable, open the valve of sewage draining exit 17 again, spissated foam is discharged from by sewage draining exit 17 by contaminants collector 16, and treated water flows into by water outlet 20 and cultures the pond.After treating that jet-pump and water pump 3 operations are normal, the aquifer yield size of observing water outlet 20 covers sealing cover 19.
Oxygenation part is made of air suction pipe 1, valve B15, ejector B13, inlet pipe B12 and oxygenation 11, when carrying out foam separation, after treating that jet-pump and water pump 3 operations are normal, open valve B15 again, when current are flowed through inlet pipe B12 by ejector B13, utilize the jet current principle of Venturi ejector, during by suction line continuously, air is regulated the air input size by valve B15 to ambient air, gives the water body oxygenation through ejector B13 by oxygenation 11 ejection by air suction pipe 1.Airflow from oxygenation 11 ejection makes aquaculture water be turbulence-like and circulates forward, and the water in the fishing breeding pond is constantly repeatedly finished the aqueous vapor building-up process, has formed enough oxygen enrichment current.Be dissolved in the medium and small bubble of oxygen enrichment current and flow before with current direction, be difficult at short notice emerge, thereby prolonged the dissolution time of air in water, improved the dissolution rate and the meltage of water body dissolved oxygen.
When need to this equipment clean, maintenance or when mobile, can open water shoot 10, the intravital water of jar is discharged, just can lightly propose, move and carry out work.
