Abstract

The utility model relates to a micro-porous oxygen feeding plate, which consists of a micro-porous nano tube, a framework and a connecting hose. The micro-porous oxygen feeding plate is characterized in that the micro-porous nano tube is coiled in an incense coil shape and is fixedly connected with the circular framework which is provided with a radiation cross-shaped outer ring, the port of the outer end of the incense coil-shaped micro-porous nano tube is closed, and the port of the inner end of the incense coil-shaped micro-porous nano tube is connected with the connecting hose and a fresh compressed air source. The utility model can be used as the oxygen feeding equipment in the high-density waters for aquatic products such as fish, shrimp, crabs and the like, and has the advantages that the diameters of micro bubbles overflowing from the micro-porous nano tube are less than or equal to 3.8 nm, the micro bubbles can be fully contacted with water for gas-liquid exchange, the time required to reach the saturated amount of dissolved oxygen in breeding waters is shortened, the structure is simple and durable and has resistance against acid, alkali and sea water, the oxygen feeding effect is good, and the oxygen feeding efficiency is high.

Description

The porous nano oxygen increasing disc

Technical field

The utility model relates to a kind ofly propagates the device of waters delivering oxygen artificially to fish, shrimp, crab and so on aquatic organism high density, specifically is the porous nano oxygen increasing disc.

Background technology

Along with expanding economy, people's material requisite improves constantly, and a lot of the product of self-sow far can not satisfy the growing needs of people as aquatic products such as fish, shrimp, crabs, need propagate artificially, replenishes the market demand continually.But propagate aquatic products artificially, particularly high density is propagated aquatic products such as fish shrimp crab artificially, and is very close with the height relation of breeding water body oxygen content.The dissolved oxygen amount of breeding water body directly influences food ration, food digestion absorption ratio, growth rate and the feed coefficient of culturing object.Dissolved oxygen amount is not enough or low excessively, in the time of can not satisfying the aquatic organism needs, and the fishes and shrimps food of not only not pursuing progress, slow in reacting, poor growth, even large quantities of death by suffocation.Traditional float-type impeller automatic aerator and submersible type aerator, respectively from the shallow table water surface or water-bed to culturing waters oxygenation, certain oxygenation effect is arranged, but all there is big, the inefficient deficiency of energy consumption, the rotation of used impeller also can injure the aquatic organism that draws close to it, culturing the waters current bottom sludge that also can rise, influence the aquatic organism living environment.Existing a kind of oxygen-increasing device with aeration head, its weak point is to fix because of its pipeline, complex structure, and parts are many, aeration head easily stops up, dismounting, cleaning maintenance difficult, the bubble that aeration head produces in water is big, converges easily, the rate of climb is fast, time of staying weak point in water, oxygenation efficient is low, and energy resource consumption is big.

Summary of the invention

In order to overcome existing Spiralism type, submersible type and big, the inefficient deficiency of oxygenation of aeration hair style aerator ubiquity energy consumption.The utility model provides a kind of porous nano oxygen increasing disc oxygen-increasing device, makes it simple in structure, and easy accessibility is sturdy and durable, significantly improves oxygenation efficient.

The technical scheme in the invention for solving the technical problem is: a kind of porous nano oxygen increasing disc, by porous nano pipe, framework be connected flexible pipe and form, it is characterized in that the porous nano pipe is incense coil shape and is connected with the frame fixation that includes radiation M shape outer ring circle; The mouth of pipe sealing of the outside one end of the above-mentioned porous nano pipe that is incense coil shape, the mouth of pipe of an inboard end be connected the connection of flexible pipe pipe, inner chamber communicates therebetween; One end of connection flexible pipe is connected with the fresh compressed air source from oxygen increasing pump; Evenly being covered with around the tube wall of the above-mentioned porous nano pipe that is incense coil shape has intensive inside and outside ventilative micropore, exposes diameter≤3.8 millimicron of microbubble through this micropore.

The beneficial effects of the utility model are simple in structure, easy accessibility, sturdy and durable, need not maintenance, after entering incense coil shape porous nano pipe from the fresh compressed air of flexible pipe input, the terminal port sealing of pipe, the compression fresh air that pumps into can only expose in the numerous intensive micropore of porous nano pipe, and the little shape bubble that forms countless intensive diameter≤3.8 millimicron enters cultures in the waters, slowly overflows in the breed waters of 1.5～2 meters of the depth of waters, oxygen in the microbubble is fully absorbed by water, dissolved oxygen amount in the water reaches 〉=6.8 grams per liters very soon, and the time of the dissolved oxygen that reaches capacity is short, the saving energy, adopt the good porous nano pipe of material, the erosion of energy acid and alkali-resistance and seawater, not fragile, durable, need keep in repair hardly, easy to use.

Fig. 2 is the connection relation figure of the utility model and fresh compressed air source oxygen increasing pump.

In Fig. 1, Fig. 2,1. incense coil shape porous nano pipe, 2. framework 3. connects flexible pipe, and 4. arm 5. is responsible for, 6. Roots's oxygen increasing pump.Arrow among the figure is meant the flow direction in fresh compressed air source.

Embodiment

In Fig. 1, a kind of porous nano oxygen increasing disc, by porous nano pipe (1), framework (2) be connected flexible pipe (3) and form, it is characterized in that porous nano pipe (1) is incense coil shape and fixedlys connected with the framework (2) that includes radiation M shape outer ring circle, the mouth of pipe sealing of the outside one end of the above-mentioned porous nano pipe that is incense coil shape, the mouth of pipe of an inboard end is managed connection with being connected flexible pipe (3), and inner chamber communicates therebetween, and the other end of connection flexible pipe is connected with the fresh compressed air source from oxygen increasing pump (6); Evenly be covered with around the tube wall of the above-mentioned porous nano pipe (1) that is incense coil shape intensive inside and outside ventilative micropore is arranged, millimicron overflow from water diameter≤3.8 of the microbubble that exposes through these micropores, these microbubbles fully contact with water, the exchange of generation gas-liquid, oxygen dissolves in the purpose that reaches efficient oxygenation in the water.The oxygen increasing disc of formula under water that diameter is 1.5 meters can be supported 450 square metres of effective oxygenation areas growing the waters, the framework (2) that includes radiation M shape outer ring circle can be made in advance with reinforcing bar or plastics, its diameter is at 0.5～2 meter, 30～100 meters of the length of porous nano pipe, the size of optic disk and deciding, 14 millimeters of the external diameter Φ of porous nano pipe, 10 millimeters of internal diameter Φ.In Fig. 2, the oxygen increasing disc made from be connected flexible pipe (3), arm (4), be responsible for (5), oxygen increasing pump (6) pipe connects.The utility model number of oxygen increasing disc is not in actual use limit, and a plurality of oxygen increasing discs in parallel are suspended on breed waters bottom, very suitable scale high-density breeding needs with support or rope simultaneously.
