Description

Backpulsing collects the latent husky pond of culturing of blowdown Double bottom automatically

Technical field:

The utility model relates to aquaculture device, relates in particular to a kind of backpulsing and collects the latent husky pond of culturing of blowdown Double bottom automatically.

Background technology:

Japonicus claims car shrimp, flower shrimp, ring shrimp, zebra shrimp again, extensively is distributed in India, the Pacific region, and coastal on the south China Jiangsu Province all have a distribution.Japonicus have growth rapidly, premunition is not strong, dried up dead for a long time, is fit to the long-distance dried fortune pin of living.The japonicus meat is solid, protein abundance, and delicious flavour, fresh and alive edible other tool local flavor is welcome by deeply the domestic and international market.The Japanese likes eating something rare japonicus T﹠B, and the Japanese market is in great demand to fresh and alive japonicus, and price is high for a long time.World's prawn culturing is stored up foster japonicus since Japanese in 1902.Purpose at that time is not to consider the prawn growth, but obtains seasonal variations in price.By 1933, Teng Yongyuan did doctor just in the breed that has truly begun japonicus.Up to now, japonicus is still main shrimps in culture in Japan.China begins to introduce the japonicus examination from the eighties and forms merit, has obtained favorable economic benefit.Therefore, development in recent years is very fast, has all carried out breed from Hainan to Liaoning.The cultured area of present national japonicus has 1,000,000 mu approximately.The shrimp farming aquaculture models of raising together with that adopt with multiple stocking and multiple fishing more.Generally put three batches of shrimp seedlings in that Southern Shandong Province is coastal, and raise together with, but output is very low with shellfish and swimming crab, general single batch, the autumn stubble that particularly price is high, general 667m ²Has only the 5-10 kilogram.Therefore, japonicus can not satisfy the demand of domestic market for a long time.The factor of restriction japonicus raising output is except that prawn disease at present, and cultivator also is one of main factor.

Japonicus has the husky habit of diving, and cultures survival rate and significantly reduce under nothing is dived husky condition.Culture japonicus in the pond of shop sand, because density is big, it is big to cause daily ration, feeding quantity, and residual bait is many, and prawn ight soil is many, and the precipitation of algae death and suspension makes sand bed bear the accumulation of dirt very soon in addition.Like this, discharge, enter between the grains of sand and accumulate always have dirt in small, broken bits even the bulky grain dirt is screwed into central authorities.If the water of sand bed is static stagnant water, water temperature height in addition, dirt is very fast to rot smellyly, makes the sand bed blackening, just japonicus can't be perched, causes morbidity dead.At present, spread husky cultivator at the bottom of using two layers, water is added from top, discharge down, because the grains of sand can not be too thick from sand, sand bed can not be too thin, the husky net of retaining is arranged under husky, and dirt particle still can accumulate between the husky online grains of sand space of retaining, and the time one is long, still the sand bed blackening can occur and foul, cause japonicus can't perch and the dead problem of falling ill.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, providing a kind of can thoroughly recoil away the dirt of sand bed, fundamentally overcome the critical defect that the sand bed blackout fouls in the breeding process, realization cleaning, healthy foster shrimp, the backpulsing that improves breeding density and output collects the latent husky pond of culturing of blowdown Double bottom automatically.

The purpose of this utility model can realize by following technical measures:

Connect substrate under the pool wall, be connected with the porous plate that is connected in the pool wall inwall by several pillars in the substrate, the husky net of retaining is arranged on the porous plate, retaining sand has sand bed on the net, pool wall is provided with several spout holes, every Kong Jun is furnished with stopper or is connected with valve, be provided with the gas upspout in the pond, pass through sand bed under the gas upspout successively, keeping off husky net is connected with substrate with porous plate, tail end is provided with the inlet opening under the gas upspout, is equipped with annular conduit in the substrate, connects the annular conduit of annotating drainpipe and is provided with several water holes, substrate is connected with sewage well on the middle part, and suitable for reading have the bottom of the sewage well of cover net to be provided with the mudhole that is communicated with blow-off pipe.

The purpose of this utility model also can realize by following technical measures:

Each water hole on the annular conduit is in same horizontal plane, and the water hole density difference at each position; The all upper and lower settings multilayers of pool wall ring spout hole, every layer spout hole is uniform on same horizontal plane; Cover net is a multilayer, and it is big that each layer mesh becomes from top to bottom gradually; Annotating drainpipe, blow-off pipe is connected with the notes draining valve, the blowoff valve that are positioned at the pool wall outside respectively; The end of sewage well, is tapered, and cover net is a multilayer, and it is big that each layer mesh becomes from top to bottom gradually.

There is mudhole at the middle part at the bottom of the utility model pond, but by opening the blowoff valve automatic pollution discharge.At the bottom of the pond outside sewage well, establish the ring pipe that has the water hole, annotate draining valve, can change water, draining by sand bed by opening.Be that about 40 purposes are kept off husky net below the sand bed, run off, keep off husky net and be layered on the porous plate in order to prevent sand bed.Porous plate can be various material such as cement, bamboo and wood, plastics.Under the porous plate pillar is arranged, in order to support porous plate and husky weight.The husky pond of culturing dive at the bottom of these two layers when foster shrimp running, and the sewage well cover net that the different meshes of multilayer are arranged suitable for reading carries out automatic pollution discharge by small amount of water in short-term, and prevents that prawn from escaping from by sewage well.A large amount of change water, draining is to be discharged through annotating draining valve by the water hole after seeing through sand bed.Change water at every turn like this, draining can both be washed sand bed, does not gather permanent stagnant water in the sand bed thereby make.The innovative point of core is a backwash sand, when promptly the prawn in water feeder is changed water, can improve hydraulic pressure by annotating draining valve, water injection pipe, the water filling from the pond of the pond bottom on sand bed of ring pipe and water hole, make new water see through sand bed from the bottom and spring back over sand bed top, discharge by spout hole again.Sand bed hardens or when uneven, available founding rake stirs gently, makes the recoil current evenly have ground, dead angle the dirt that accumulates in the sand bed recoil away, outside the discharge pond; And stir water by the splash bar of belt scraping plate, the various dirts that attach on the sand are discharged outside the pond to greatest extent, thereby can under the condition of high water temperature, realize permanent the breed and that the sand bed blackening can not take place is smelly.The latent husky environment of japonicus can remain pure and fresh.So just can improve breeding density, improve output.In addition, the utility model also is suitable for the high yielding culture that all bury the aquatic animal that dwells.

The utility model is provided with some gas upspouts, and the bottom of the outer sand bed of sewage well is inserted in the bottom of gas upspout; The bottom of gas upspout has several inlet openings, when the gas exhausting stone of putting into when the gas upspout looses gas by fan blower, with the gas upspout suitable for reading maintain an equal level or lower slightly pipe in water level will raise, in the breed pond outside pipe of overflowing.The gas exhausting stone of these gas upspouts resembles a platform water pumper, continuously the water of bottom is extracted into the upper strata, upper water sees through sand bed again and is back to bottom, form vertical convection, continuously wash sand bed, making the latent japonicus that is embedded in the sand bed continuously accept the flushing of fresh water, obtaining sufficient oxygen at any time.

Automatically collection blowdown intensive culture method at the bottom of two layers of the japonicus backpulsings of the present invention, the angle is smeared for circular or square, rectangle that length and width are close in the pond of design, and it is dirty to make it the horizontal circulation of easy formation central authorities collection.The method that forms circulation is a lot, by adding water along the pool side orientation, can form circulation.If amount of water is little, flow velocity is not enough, is not enough to form necessary circulation, can form the dirt of circulation collection by directed aerator.Directed aerator has Waterwheel-type, jetting type etc.As long as form certain circulation in the pond, dirt will concentrate on the top of the sewage well at middle part.Sewage well top is provided with the multilayer cover net, prevents that japonicus from runing away when blowdown.Lowermost one deck is large mesh C, can prevent that the finished product shrimp spills.Middle one deck is middle mesh B, can prevent that the semi-finished product shrimp spills.Uppermost one deck is fine mesh A, can prevent that the small dimension juvenile prawn spills.Just put seedling and cultured, can blowdown, only use and change water drainpipe or the sand surfing of gas upspout, treat detailed catalogue anti-escape to net begin blowdown when A does not leak the shrimp seedling again.Along with japonicus is grown up, when reaching the semi-finished product shrimp, then the upper strata fine mesh wire is extractd, unobstructed in order to blowdown.Equally, long when undermost large-meshed net C can not leak when shrimp, the middle order net B excision in middle level, the blowdown meeting is more smooth and easy again.Blowdown operation is as long as open blowoff valve, and the dirt on the cover net just can be discharged automatically.

When normally changing water, upper water keeps off husky net and porous plate and arrives bottom through sand bed, is discharged through annular conduit, notes drainpipe and notes draining valve by the water hole again, and this is first kind and is just washing sand.By inflation incessantly in 24 hours, the gas exhausting stone in the gas upspout constantly ejected the mouth of pipe water surface to the water in the pipe, overflows to the top water body.And bottom water cognition constantly enters upspout by the inlet opening, and the water that reduce the bottom is then replenished via sand bed infiltration downwards by upper water continuously, thereby has just ceaselessly realized that second kind is just being washed sand.

Recoil to add to stir by this backpulsing two-layer sand buried breeding apparatus and wash sand, can thoroughly dash the dirt that removes in the above sand bed of the husky net of retaining, adopt the gas lift water body to realize vertical convection; Automatically collect dirty, blowdown by horizontal circulation; It is smelly that sand bed is no longer turned black, and it is pure and fresh that the latent husky environment of japonicus is remained, and the prawn metabolism is vigorous, keep high health status, effectively control leukodermal breaking out, growth rapidly, so just can realize cleaning, healthy shrimp, raising breeding density, the raising output of supporting.
