Embodiment
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
a kind of aquaculture aeration system shown in Figure 1, this aeration system comprises for the compressed-air actuated air accumulator 2 providing compressed-air actuated air compressor 1, produce for stored air compressor 1, the air supply header 3 being connected to the band air feed main valve 31 at air accumulator 2 gas outlet place, is connected to the gas manifold 4 with pressure-reducing valve that air supply header 3 exports, is positioned at multiple oxygen-increasing devices 5 in pond used for aquiculture, in the present embodiment, all oxygen-increasing devices 5 in same pond are all spaced apart along same circumferencial direction.
as shown in Figure 2, oxygen-increasing device 5 comprises the bottom bracket being provided with oxygen increasing tube 53 with the top board 51 of ball float, the side plate 52 being around in top board 51 weeks outside, row, side plate 52 offers targeting port 54, the targeting port 54 on all oxygen-increasing devices 5 in each pond distributes all clockwise or counterclockwise.The circumferential side wall of the oxygen increasing tube 53 on bottom bracket offers multiple micropore communicated with its tube chamber, and the mouth of pipe of oxygen increasing tube 53 is connected to the pipe exit on gas manifold by tube connector 6.In the present embodiment, oxygen increasing tube 53 or in parallel or series connection or be fixed on across on this bottom bracket.And the pressure-reducing valve 41 gas manifold 4 is also provided with for regulating arm supply gas pressure, and the manometer 42 be provided with after pressure-reducing valve 41 for monitoring gas manifold 4 supply gas pressure, by arranging pressure-reducing valve 41, supply gas pressure can be regulated according to the aerobic situation of aqueous bio in pond.
shown in Figure 1, when to water oxygenation, by providing compressed air in the oxygen increasing tube 53 of gas manifold in pond on each oxygen-increasing device 5 bottom bracket, compressed air discharges air by the micropore in oxygen increasing tube 53 circumferential side wall in water body, increases the oxygen content in water body.Simultaneously, water body is driven upwards to flow, current limit by the structure of oxygen-increasing device 5, by targeting port 54 outwardly, targeting port 54 because of all oxygen-increasing devices 5 in pond is arranged in distributing clockwise or counterclockwise, thus drive water body in flowing clockwise or counterclockwise, like this, not only increase the dissolved oxygen ability of water body, and also can reach same oxygenation effect without the need to being covered with oxygen increasing tube 53 in pond, simultaneously by water body same circumferencial direction or be similar to same circumferentially clockwise or counterclockwise flow, drive bottom water to produce biogenic excreta to gather, be convenient to cleaning, decrease artificial.
in the present embodiment, pond has multiple, and accordingly, the gas manifold 4 that the pipeline exit of air supply header 3 connects has multiple.In the present embodiment, have at least the pipe of a gas manifold 4 to export to be connected with the mouth of pipe of the oxygen increasing tube 53 bottom all oxygen-increasing devices 5 in a pond accordingly.By arranging air accumulator 2 after air compressor 1, the supply gas pressure in air supply header 3 pipe can be stablized, in tank Stress control between 0.45 ~ 0.6MPa to guarantee the supply gas pressure from air accumulator 2 arm farthest.Because total overpressure is high, and have air compressor 1 to provide Compressed Gas continuously, the gas transport distance in air supply header 3 can be made like this to extend, the longlyest reach 1000 meters, like this, without the need to arranging the object that feeder can reach water oxygenation in pond in each pond.
in order to while cost-saving, improve oxygenation efficiency, in the present embodiment, oxygen increasing tube 53 is made up of plastic pipe, plastic pipe has good elasticity, when in managing, the blowing pressure reaches certain value, micropore on oxygen increasing tube 53 expands and blows gap open, Xiang Chizhong is filled with air, air and water body friction produce oxygen to meet the demand of aqueous bio to oxygen, and when stopping is in oxygen increasing tube 53 during air feed, hydraulic pressure is greater than the air pressure in pipe, micropore is inwardly closed, the micropore on the impurity blocking oxygen increasing tube in anti-water-stop body.
in order to while water oxygenation, kill the noxious bacteria in water, shown in Figure 1, this aeration system also comprises the ozone generator 7 passing into ozone in system, ozone generator 7 can be connected between air accumulator 2 and air supply header 3, also can being connected on air supply header 3, effectively can killing noxious bacteria in water body by passing into ozone in water body.
in order to prevent air compressor 1 oily substance of carrying when producing compressed air from entering in water body, oil water separator 8 being set between air compressor 1 and air accumulator 2 or on air supply header 3, making the compressed air that passes in water body more pure.
in sum, aquifer cultivation aeration system of the present invention, by arranging air compressor, ozone generator, air accumulator, air supply header, the gas manifold being provided with pressure-reducing valve, oxygen-increasing device to reach the oxygen demand meeting aqueous bio in pond, equipment is easy for installation, install oxygen-increasing device without the need to each pond can complete air feed object, decrease energy consumption, and noiselessness pollutes, the noxious bacteria in water body has been killed while oxygenation, the micro-pore oxygenation pipe low price adopting plastic pipe to make, not easily blocking, long service life, saved cost.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
