Detailed description of the invention
A kind of water circulation blowdown cultivation apparatus of indoor industrially-cultured Penaeus vannamei,
In figure: 1, arc-shaped transition angle, 2, gradient direction, 3, waterwheel, 4, separation net, 5, isolation frame, 6, pool wall, 7, sewage draining exit, 8, blow-off pipe, 9, water-inflow and drain valve door, 10, vertical tube, 11, micro-pipe.
Culturing pool: cultivating workshop uses hot house or glass steel tile booth to bind, and culturing pool open area is 80m2-200m2, depth of water 1.2m-1.5m；Chi Kou is the biggest or the least effect is bad, and pond mouth is circular, and preferably square takes second place, rectangle effect relative mistake some.
Pool wall with at the bottom of pond: pool wall with at the bottom of pond: the corner of vertical pool wall should not use right angle, is done camber with cement, has both prevented the dead angle of remaining dirt, avoids prawn possible mechanical damage occur simultaneously；Chi Dipaiwukou is preferably disposed in centre, and four base angles and the gradient of four bases and sewage draining exit at the bottom of pond are 1%-2%；If sewage draining exit is located at the centre of culturing pool one end, four base angles and the gradient of four bases and sewage draining exit at the bottom of pond are 2%-3%.At the bottom of pond and pool wall is smooth, preferably spraying paint before cultivation, spray paint and can reduce the vivosphere of pathogenic microorganism, the time of spraying paint is carried out for cultivation water inlet for first 1 month, typically sprays paint 1-2 time.
Separation net and isolation frame: mesh size is with damaged 1 mesh of separation net, and minimum gauge prawn is without fleeing from or being standard without blocking prawn；If possible, separation net can be changed with one or many during cultivation, to adjust mesh size, increase filth-discharging effect, when prawn specification is less than 7cm, monthly change a separation net, during prawn 7cm-10cm, every separation net of replacing the most month in and month out, prawn specification is more than 10cm, monthly changes 4 separation nets.Being embedded in by separation net in isolation frame, separation net is circular or square, and radius or the length of side are 10cm or 15cm；Isolation frame is covered on sewage draining exit by screw or other form, it is desirable to sewage draining exit horizontal edge and isolation frame clamping fixing, and contact surface smooths, it is to avoid gap occurs and remaining deposit；If isolation frame makes convex the radius increasing isolation frame or the length of side, filth-discharging effect can be more preferably.
In actual production operates, use circular bamboo cover curtain as isolation frame, on cover curtain, port radius is 15cm, it is highly 12cm, the gauze of the suitable mesh of overcoat as required, gauze is close to cover curtain outside and is fixed on cover curtain, at the bottom of tight-lipped patch pond, cover curtain limit, if desired with the gap between at the bottom of the filling cover curtain Bian Kou such as gauze and pond, generally use weight and be pressed on cover curtain；In the case of not having suitable sewage draining exit, water pump can be placed on waste removal position, water pipe passes cover curtain and etting, by the electronic blowdown of water pump, and 1 cun of immersible pump of many uses, each draining in morning 4h.
Arranging micro-pipe oxygen supplement at the bottom of pond, micro-pipe is 1cm-2cm from height at the bottom of pond；After culturing pool enters full water, lay four waterwheels in four corners in culturing pool saliva face；During carrying out prawn culturing, near sewage draining exit, put 1-5 the free gas exhausting stone that can artificially move；
Blow-off pipe: whole external form substantially l-shaped, blow-off pipe diameter 15cm-20cm, pvc pipe；In pond, short tube is blowdown water inlet pipe, long 3cm-5cm, vertically, is embedded at the bottom of pond and connects horizontal tube one end by joint；Horizontal tube is to be embedded at the bottom of pond and the most downward-sloping horizontal blow-off pipe, and horizontal tilt angle is 5 °；The water-inflow and drain valve door of another termination pond threeway in addition of horizontal tube；Water-inflow and drain valve door upper end open connects pvc pipe but interface is Active Interface, this pvc pipe and horizontal plane, height with cultivation during peak level maintain an equal level.
