Description
Technical field
The invention belongs to Aquatic product equipment technical field, be specially a kind of fishery auxiliary cultivation apparatus.
Background technology
China is the first in the world aquaculture big country, accounts for about the 70% of world aquaculture total amount.How to change existing aquaculture model, improve cultivation operating automation degree and water treatment efficiency, all the development of aquaculture current on China will have appreciable impact.
During aquaculture, the most serious two problem can be there is, one is that As time goes on and significantly the concentration of the carbon dioxide in water body can rise, generally reach 20～100 times of surrounding saturated concentration, and carbon dioxide has the alkali effect that disappears and makes the pH value rapid decrease of water body, the heavy damage acid-base balance of water body, the control to circulating water culture system causes the biggest difficulty；Two is As time goes on to increase substantial amounts of solid particulate matter in breeding water body, these solid particulate matters are mainly derived from fish faeces, residual bait and fish body deformed limb etc., and the long stop in water body of these solid particulate matters can cause: corrupt decomposition produces ammonia and other noxious products；Blocking waste water processes biofilter, limits the bearing capacity of system；Catabolic process consumes oxygen；The directly infringement fish gill, reduces fish growth speed etc..
So, how to be effectively reduced the content of aquifer cultivation carbon dioxide in process with remove aquifer cultivation during finely ground particles become the most important thing of aquifer cultivation development.The general mode using ventilation removes CO2, but removal effect is inconspicuous, and it is long to process the time.Also there is Chinese patent CN02139079, a kind of carbon dioxide from aquaculture water removal device, including a tower body, at least one of which is located at the packing layer within described tower body, one inlet pipeline connecting described tower body top, one outlet pipeline connecting described tower body bottom, one air outlet being located at described tower body center of top, and one be located at the air inlet that described tower body sidewall is slightly above the outlet of tower body wall, also include in the air outlet that a negative pressure air draft apparatus, the lower end of described negative pressure air draft apparatus are matched with described tower body top.And for example CN101642075B, a kind of carbon dioxide removal device in fishery water body, it includes a body, the upper outside face of described body is provided with water inlet, portion is provided with and sprays and formed multi-level vaporific water curtain and the most unrestrained annular water injector along its horizontal diameter direction on the body, and described water inlet couples with described annular water injector；The one side of described body lower part is provided with air inlet, and described internal lower central is provided with the aerator of the most uniform release air microbubble, and described aerator connects with described air inlet；This internal middle part is provided with the filler chamber promoting that carbon dioxide carries out gas exchange；The top of described body is provided with the moisture trap excluded by carbon dioxide and hood assembly；The another side of described body lower part is provided with the outlet of clean water；The blow-off pipe described intrinsic deposit dirt excluded and controlled valve it is provided with in the bottom of described body；Described aerator is made up of an aerator assembly and the aeration plate being arranged on aerator assembly top, some inverted tusks it are provided with on the arch back side of described aeration plate, it is provided with through flow hole between described tusk, be provided with the one-way cock of automatic shutter between described aerator and described air inlet, described aerator by a mounting structures part be fixed on described internal；Being equipped with a gear on described aerator assembly, the long-pending air cavity channel perisporium of described aerator assembly is provided with some ventholes, described gear is arranged on the top of described venthole.
But this kind of apparatus structure is complex, and need that water body is extracted out culturing pool and just can carry out filtering removing carbon dioxide in solid particulate matter and water body, the existence of Fish during water body filtration removing carbon dioxide in carrying out culturing pool cannot be ensured, therefore, in use need to treat that culturing pool Mesichthyes grows up to pull out and could use.
Summary of the invention
So that just can carry out culturing pool clearing up solid particulate matter removing carbon dioxide during fish culture, it carries out continual fish culture in realizing culturing pool body, and the present invention provides a kind of fishery auxiliary cultivation apparatus.
For realizing above-mentioned technical purpose, the concrete technical scheme that the present invention takes is: a kind of fishery auxiliary cultivation apparatus, for culturing pool, including one and the above filter mechanism being positioned in culturing pool, main QI invigorating pipeline, two and above auxiliary air compensating pipeline, aerator and ozone machine；Described filter mechanism includes metal screen frame, the filler being positioned in metal screen frame, and metal screen frame is hung on the pool wall of culturing pool；Main QI invigorating pipeline is arranged vertically within the centre of culturing pool, and one end of main QI invigorating pipeline exceeds the water surface, and the other end is positioned at the bottom of the pond of culturing pool；Auxiliary air compensating pipeline is distributed at the bottom of the pond of culturing pool, and one end is closed, and other end opening, one end of opening is connected to main QI invigorating pipeline and is positioned at one end at the bottom of pond of culturing pool；Aerator and ozone machine are respectively positioned on the water surface, and the gas outlet of aerator and ozone machine is concurrently accessed main QI invigorating pipeline and is positioned at one end of the water surface；On described main QI invigorating pipeline, auxiliary air compensating pipeline, the part in being positioned at water body is provided with several equally distributed holes, a diameter of 5-10mm in hole.
As the technical scheme of the improvement of the present invention, aerator is different from the occurrence frequency of ozone machine, and the occurrence frequency of aerator is the twice of the occurrence frequency of ozone machine.
As the technical scheme of the improvement of the present invention, metal screen frame is when being installed on the pool wall of culturing pool, it is ensured that the bottom of metal screen frame exceeds 5-10cm at the bottom of the pond of culturing pool.
As the technical scheme of the improvement of the present invention, described filler includes the material of following weight portion: plasticity synthetic resin 1-3 part；Aluminium sesquioxide 10-15 part；Calcium hydroxide 15-23 part；Manganese sand 9-14 part.
As the technical scheme of the improvement of the present invention, on described metal screen frame, the particle size being smaller in size than filler of mesh.
Beneficial effect
Aerator is used in mixed way with ozone machine, air and ozone it is passed through in culturing pool, promote that in culturing pool, water circulates under the drive of gas, and then the solid particulate matter in culturing pool also can be with water body flow, the filter mechanism being eventually hung on cultivation pool wall filters, carbon dioxide in water body also can filled be assimilated simultaneously, finally realizes the purification of water body.
