With the floating barrel floating on the water, when the utility model works, the electric motor provides dynamic force to drive the oxygen increasing blade to rotate in the water, and the air is sucked into the water through the small air inlet holes on the blade, making the water area become to an oxygen rich area.
Description
The utility model belongs to the employed mechanical devices in field such as environmental protection, waste water treatment and aquaculture.This device is to charge into gas in liquid, and the content that increases gas in the liquid is the machinery of oxygenation in water especially.By oxygenation the biochemical process of sewage is handled and be carried out, can make the oxygen content of water body in the fish pond improve assurance fish pond stable high yield.
Existing various oxygen-increasing device is divided into two kinds of basic methods of operation, a kind of is water sports, as vane type, Waterwheel-type, jetting type, water burst formula aerator, a kind of is that oxygen injects, as the inflatable oxygen-increasing device, the former impacts water body with strong agitation, makes spray raise out the water surface and counts the airborne oxygen contact of Mi Yuanyu or make the water high velocity jet suck water body to oxygen, and the latter will start large blower the aerator that oxygen compression back feeds is under water carried out oxygenation.This two classes oxygen-increasing device exists all that energy consumption is big, oxygen transfer efficiency is not high and the operation noise is big, the weakness of interference environment.It is better that last class oxygen-increasing device is used for the water body oxygenation effect of shallow water position, but the oxygenation effect of deep water just is greatly affected.In addition, to can produce the sewage of a large amount of bubbles in oxygenation process, foam can hinder liquid level and absorb oxygen, and oxygen-increasing devices such as vane type, water burst formula can't use.It is good that back one class oxygen-increasing device is used for darker treatment tank oxygenation effect, but if when being used for water level shallow and fish pond that the water surface is more vast and treatment tank, its effective oxygenation scope is just inadequate, lays a large amount of gas distribution pipeline and aerator unless throw huge fund.
In order to overcome above-mentioned deficiency, the utility model has designed a kind of new-type oxygen-increasing machine, and purpose is energy savings, reduces noise, protection environment, improves the efficient of oxygenation.Do to flow fast without the strong agitation water body and also need not pressurization to oxygen and just can carry out oxygenation effectively.According to hydromechanical basic principle, the streamlined object that in fluid, moves, pressure on its side can be much smaller than the static pressure of fluid under a stable condition, the decay of this pressure is with regard to the negative pressure suction force that constituted convection current line style object side surface (overwhelming majority that this attraction provides airfoil lift to jet-propelled airliner of modern times---can up to more than 3,000,000 newton---); In addition, the negative pressure suction force that is subjected to much smaller than its side of the resistance of motion of fairing.Utilize above-mentioned principle that this device is designed to streamlined air suction type structure, the resistance of motion is very little when making device busy, and the energy of consumption reduces greatly, but can automatically suck oxygen in the water in large quantities simultaneously, thereby obtain higher oxygenation efficient.
Streamlined air suction type aerator includes: case (1), electromotor (2), floating drum (3), decelerator (4), hollow turning cylinder (5) and oxygenation blade (6).The utility model adopts the one-level pulley decelerates, speed reducing ratio is 1:3:5, electromotor (2) is connected with the input of decelerator (4), output links to each other with Hollow Transmission Shafts (5) by belt pulley, Hollow Transmission Shafts (5) welds together with oxygenation blade (6), case (1) is fixed on the decelerator (4), cover electromotor (2) and decelerator (4) in case water logging, and case (1), electromotor (2), decelerator (4) and Hollow Transmission Shafts (5), oxygenation blade parts such as (6) swim on the water surface by the floating drum (3) of three symmetric arrangement, floating drum (3) links to each other with decelerator (4), also can be without floating drum (3) for this device that continental rise uses.Oxygenation blade (6) is made the streamlined hollow structure, the leading edge (8) of oxygenation blade (6) is wanted fairing, slick and sly, trailing edge (9) is sharp-pointed, oxygenation blade (6) can weld together with Hollow Transmission Shafts (5), the cavity of oxygenation blade (6) is connected with the cavity of Hollow Transmission Shafts (5), constitutes inlet channel, in the side of oxygenation blade (6) is to be drilled with the air inlet aperture (10) that many diameters are 1～2mm on the relevant position of suction surface.The side of oxygenation blade (6) can use general metal or density material mechanical such as nonmetal to process, also can use micro-porous permeable material (as cellular plastic, alumina sintering porous material etc.) directly to make, numerous air inlet micropore will be arranged like this.Hollow Transmission Shafts (5) be higher than the water surface lateral location or the axle the top have air inlet (7).Provide power by electromotor (2) during operation, drive several oxygenation blade (6) rotations through decelerator (4) by Hollow Transmission Shafts (5), after oxygenation blade (6) rotates in water, a large amount of gases are inhaled in the water by the air inlet aperture (10) of the suction surface of oxygenation blade (6), make oxygenation blade (6) waters on every side become oxygen-rich area very soon.Also be able to dissolved oxygen in order to make from oxygenation blade (6) water body far away, this device with oxygenation blade (6) do with the rotation Hollow Transmission Shafts (5) between become a little lead angle α, desirable 5 °～20 ° of α, make oxygenation blade (6) water body on every side have one to flow slowly like this, by flowing the water of anoxic is taken near the oxygenation blade (6), flow to the waters of other anoxic after the oxygenation again, further improve the dissolved oxygen amount of water body by convection current, diffusion.
