Abstract
The invention discloses an airfoil-type water-plowing aerator applicable to aquaculture and water treatment. The airfoil-type water-plowing aerator comprises an impeller-type aerator and a deflector plate (5), namely, on the basis of the impeller-type aerator, the deflector plate (5) for changing the flow direction of water is installed outside an impeller (2), so that a rotational water flow generated by the impeller (2) is converted into a radiative water flow to a distance so as to promote aeration and exchange of an upper water layer and a lower water layer; and the deflector plate is fixed on a motor base (1), a support rod (3) or a buoy (4) and can also be manufactured into the support rod (3) or the buoy (4). The invention overcomes the defects of the existing aerator and water-plowing machine, has double effects and a simple structure, and meets requirements of energy conservation and environment friendliness.
Description
Technical field
The present invention relates to a kind of aerator, relate in particular to the water-plowing type aerator that a kind of breed and water environment are handled usefulness.
Background technology
In recent years, China's aquaculture progressively develops to high density, intensification direction, and this is inseparable with the widely-used of aerator.Commonly used have patterns such as impeller, waterwheel, water spray, jet, spraying, diving, Tai Ji and bottom aeration.
Paddle aerator is the most commonly used one type; Utility model CN201938219U discloses a kind of energy-efficient paddle aerator; Oxygenation mechanism is to utilize the impeller of high speed rotating to impact water body to form spray, lets the air on the water surface get into water body and realize oxygenation.Oxygenation efficient is higher, but not enough below existing:
1, oxygenation is inhomogeneous.Mainly concentrate on top layer and middle level, in the pond, form the dissolved oxygen dead angle easily.
2, the DeGrain of water correction.The current that its impeller produces; Although can push the water of the high dissolved oxygen around the aerator open, the layering of can't large tracts of land breaking water body, the efficient of levels water exchange is low; Because the bottom sediment is rich in remaining bait and excreta, increased the probability of aquaculture product morbidity.
Other all kinds of aerators respectively have different pluses and minuses, but not good to the effect of water correction.
The cultivated water machine that occurred in recent years, its action principle are through the rotation of cultivated water plate, push current to a distant place, promote the exchange of levels water, break the water body layering, and reach the purpose of improving whole water quality in pond and substrate.Weak point is: oxygenation effect is slow, must unite use with aerator, can satisfy the requirement of breed and water environment treatment.
The water-plowing type aerator that has also occurred two-in-one type on the market, publication number CN201694896U disclose a kind of " water-plowing type aerator ", and the user can be according to actual needs, start major and minor motor (oxygenation, plough water) simultaneously or work independently; Publication number CN202152303U also discloses a kind of " frequency conversion type is ploughed aerator in water ", utilizes the computer frequency-variable controller to be connected with motor, realizes the cultivated water of high speed oxygenation low speed.No matter these water-plowing type aerators are that purchase cost, use cost or equipment are installed, and two machines are installed simultaneously, not the difference of essence.
Therefore, need to seek better water-plowing type aerator, be used for satisfying the requirement of modern aquaculture and water environment treatment.
Summary of the invention
The purpose of this invention is to provide a kind of water-plowing type aerator of aerofoil profile efficiently, in oxygenation, also can realize ploughing water function, and not increase too many cost and installation difficulty, it is to realize through following technical scheme:
Paddle aerator commonly used is by motor and pedestal, impeller, and pole, suspended substance is formed, and pole one end connects motor base, and the other end connects floating drum, and floating drum is the proportion object littler than water.
Aerofoil profile water-plowing type aerator of the present invention promptly on the basis of paddle aerator, has been installed the deflector that is used to change the direction of a stream of water in the outside of impeller, and the rotary water current that impeller is made can be to the distant place radiation.
Deflector is fixed on motor base, pole or the floating drum, also can be made into pole or floating drum, and material therefor is stainless steel, aluminium alloy, plastics or fiberglass etc.
Usually, the length of deflector is more than the 20cm, preferred 50-100cm; Highly be more than the 10cm, preferred 40-80cm; Distance apart from the impeller edge after installing is below the 80cm, preferred 10-30cm.
The mechanism of action of the present invention is following:
When one, impeller stirs, form the spray of rotation, let the air on the water surface get into the water body the inside and realize oxygenation, the mechanism and the mechanism of action of this point and prior art are identical;
Two, on the basis of paddle aerator, install deflector additional; " heavy-oxygen-enriched water " after the impeller oxygenation; Changed running orbit by deflector; Promptly change " the radiation current " that flow to a distant place to " rotary water current " around the aerator into, transfer to the upper strata, realize breaking the purpose of water body layering thereby drive lower layer of water.In oxygenation, also realize efficiently ploughing the function of water.
Three, because deflector has been guided a distant place into " heavy-oxygen-enriched water ", the pressure reduction of the oxygen partial pressure of water body increasing around the impeller, it is higher relatively to make oxygen incorporate the efficient of water body.It is higher relatively that the present invention makes oxygen incorporate the efficient of water body, and every degree electricity can oxygenation more than 2.0 kilograms.
The present invention is applicable to the processing and the improvement of sealing water body and open water, such as the breeding water body of fish, shrimp, crab, shellfish, the frog, ginseng etc., and polluted water regions such as lake, river course.
The advantage that the present invention had is:
One, it is higher to make oxygen incorporate the efficient of water body, and current have promoted the even oxygen aeration of whole water body melting oxygen water lead fast a distant place and bottom.
Two, realize cultivated water function simultaneously, can break the water body layering by rapid large-area, improved substrate, reduced the influence of nitrite and colibacillus, and can promote useful algae and planktonic growth, not only replenished natural bait but also produce oxygen.
Three, easy for installation, energy-saving effect is remarkable, with respect to existing aerator, has added cultivated water function, does not but cause the significantly rising of cost, meets energy-saving and emission-reduction, requirements of green environmental protection.
Description of drawings
Fig. 1 is the perspective view of aerofoil profile water-plowing type aerator of the present invention.(this sketch map only is for principle of the present invention is described; But not be confined to the described structure of this sketch map; As can be fixed on deflector 5 on the floating drum 4, or pole 3 connections that deflector 5 usefulness are independent, can also be designed to one to deflector 5 and floating drum 4 or pole 3; Even three-in-one, be not limited thereto equally).
