Abstract
The invention discloses an aeration device for a green house soft-shelled turtle raising pond, which has an aerator and an air supply pipe, wherein the air supply pipe is connected with the exhaust opening of the aerator; the air supply pipe is connected with more than two branch air pipes; and each branch air pipe is connected with more than one closed-loop-shaped micro pore nanotube. Each micro pore nanotube is arranged in the raising pond and close to the bottom of the pond, and after the aerator is started, the raising pond can be aerated through the micro pore nanotubes. The device, which has a reasonable structure, can be arranged conveniently and has good aeration effect and low energy consumption, is an ideal aerator for the green house soft-shelled turtle raising pond.
Description
Technical field
The present invention relates to the oxygen-increasing device of aquaculture, the used oxygen-increasing device of specifically a kind of greenhouse cultivation soft-shelled turtle.
Background technology
The oxygen-increasing device that is adopted in the existing greenhouse turtle culture pond is mainly by following two kinds: 1, being joined successively by air pump, steam line and aeration stone constitutes; 2, join successively and constitute by air pump, steam line and the pvc pipe of stamping eye.The deficiency that above-mentioned two kinds of oxygen-increasing devices in use exist is: noise is big in the greenhouse, and oxygenation effect is poor; Culture dissolved oxygen skewness in the pond; The water body suspension is many, is unfavorable for water quality management, influences the soft-shelled turtle growth; Energy consumption is high.
Summary of the invention
The object of the present invention is to provide a kind of breeding soft-shell turtle greenhouse oxygen-increasing device, the oxygenation effect of this oxygen-increasing device is good, and its ability activation water body, recovery water body oneself's detergent power and energy consumption are low.
For realizing above-mentioned purpose; The present invention adopts following scheme: breeding soft-shell turtle greenhouse oxygen-increasing device; Have aerator, steam line; The exhaust outlet of steam line and aerator joins, and is connected to the bronchi more than two on the steam line, is connected to the porous nano pipe that is closed circular more than on each bronchi.
Oxygen-increasing device provided by the invention is arranged in every porous nano pipe in the breed pond and near the bottom, pond in use, starts aerator, can carry out oxygenation to culturing in the pond through the porous nano pipe.Adopt porous nano pipe aeration oxygen replenishing, have following technique effect: 1, the bubble of porous nano pipe ultra micro pore aeration generation, very big with the contact area of water in water body, the come-up flow velocity is low, and time of contact is long, and the mass-transfer efficiency of oxygen is high; 2, porous nano pipe aeration oxygen replenishing, just as water body being become hundreds of millions rivers that slowly flow, sufficient dissolved oxygen makes water body can set up the ecosystem of nature, lets water work; 3, porous nano pipe aeration through increasing the oxygen of bottom, pond, can be accelerated organic decomposition in water-bed oxygenation; 4, porous nano pipe aeration oxygen replenishing, the oxygen of generation same amount, aerator power consumption is the 1/4-1/2 of other oxygen increasing equipment power consumption; 5, porous nano pipe aeration oxygen replenishing noise is low, reduces the stress reaction of soft-shelled turtle.
The present invention is rational in infrastructure, easy for installation, oxygenation effect is good, energy consumption is low, noise is little, is the desirable oxygen-increasing device of greenhouse turtle culture pond, can be applicable to bilayer, three layers of greenhouse turtle culture pond.
Description of drawings
Accompanying drawing is the structural representation of one embodiment of the invention.
Embodiment
Further specify the present invention below in conjunction with embodiment and use-case.
Referring to accompanying drawing
Greenhouse provided by the invention turtle culture pond oxygen-increasing device has aerator 5 and steam line 4; Steam line 4 joins with the exhaust outlet of aerator 5; Be connected to the bronchi 3 more than two on the steam line 4, be connected to the porous nano pipe 2 that is closed circular more than on each bronchi 3.
In the present embodiment, each bronchi 3 joins through flexible pipe 1 and two porous nano pipes 2.Porous nano pipe 2 is the rectangle of sealing.
In the present embodiment, aerator adopts air-out vortex air pump down, and model is XGB28-210; 50 millimeters of steam line diameters, 20 ~ 25 millimeters of bronchial diameter, 10 millimeters of hose diameters; 14 millimeters of porous nano pipe diameters, 10 millimeters of internal diameters, 5 meters of porous nano Guan Chengchang, wide 1.3 meters rectangle.In use, the porous nano pipe is fixed on cultures in the pond 5 centimetres position at the bottom of the pond, cultures 40 centimetres of the depth of waters in pond.The total length of a supporting porous nano pipe of aerator is no more than 200 meters, and per 25 square metres of waters surface are with one of porous nano pipe.
Adopt oxygen-increasing device provided by the invention, can change existing surperficial oxygenation, point type oxygenation, dynamic oxygenation into bottom oxygenation, full pond oxygenation, static oxygen increasing.Use this oxygen-increasing device can eliminate thermocline, the water density layer of culturing the pond, during the oxygenation of this oxygen-increasing device, dissolved oxygen is even; Can substantially improve the especially dissolved oxygen levels of bottom water body of culturing pool body; Optimize cultivation water environment, promote the soft-shelled turtle growth, reduce and culture the incidence of disease; Dosage is significantly reduced, and the soft-shelled turtle quality of breed is guaranteed.Through evidence, adopt oxygen-increasing device provided by the invention to compare in the soft-shelled turtle greenhouse cultivation with existing oxygen-increasing device, the former has following good effect than the latter: the water body ammonia-nitrogen content descends 42%, and nitrite descends 45%; Power consumption descends 50%, and output improves 10%, and the incidence of disease descends 15%; Growth rate improves 15%, and survival rate improves 6%, and feed coefficient descends 10%; Every square metre of economic benefit improves 40%-60%, and the seed of throwing in was then cultured through 9 months, goes out the average specification in pond and reaches 750 grams.
Claims (3)
1. greenhouse turtle culture pond oxygen-increasing device; Have aerator, steam line; The exhaust outlet of steam line and aerator joins, and it is characterized in that: be connected to the bronchi more than two on the steam line, be connected to the porous nano pipe that is closed circular more than on each bronchi.
2. greenhouse according to claim 1 turtle culture pond oxygen-increasing device is characterized in that: each bronchi and two porous nano pipes join.
