Abstract
The needle bar impeller type spiral ventilator is suitable for aerating water in aquatic culture and aerating in purifying sewage, and has the features of low power consumption and high water aerating efficiency. The spiral rotor impeller has vanes of strip rigid material and a shaft. The vanes always inside water sputter rich water sprays, water drops, water bubbles and water mist to increase surface area of water, prolong contact of water to air, enhance oxygen exchange of water and air and raise the water dissolving speed of water.
Description
Stick-type impeller helix oxygen-increasing machine is used for the oxygen replenishment of aquaculture water, increases the content of the dissolved oxygen of water; Simultaneously also can reach the effect of aeration to volatilizable harmful gas removing in the water, the aerator that therefore also can be used as in the sewage disposal uses.
Mechanical enhancement is all based on " two-film theory " at present." two-film theory " thought and existed air film and liquid film two membranes at gas-liquid interface, abbreviate two films as.Two films are that oxygen molecule is diffused into the main resistance in the water body.In addition, also can have influence on the velocity of diffusion of oxygen molecule with the oxygen concentration of the atmosphere contact part water surface, promptly oxygen concentration is low, and dissolved oxygen speed is just fast; Otherwise it is then slow.Pertinent data proves, fast 100 times than the dissolved oxygen speed of still water level of the moving waters surface.Therefore, increase gas-liquid contact area, extend contact time, constantly destroy two films of having generated, constantly upgrade liquid level, can quicken dissolved oxygen, the oxygenation speed of raising water.According to the principle of " two-film theory ", design various oxygenating machines have 20 surplus kind, all exist complex structure, watt consumption is big, have want step-down gear, have want water pump, increased the cost and the maintenance cost of equipment.The contact area of also depositing water and air in addition is little, and the convection velocity of water is more slow.
Stick-type impeller helix oxygen-increasing machine of the present invention.Overcome effectively and gone up above-mentioned deficiency, speed change, power are not arranged in pairs or groups mutually with efficient, and impeller contacts evenly with water, and resistance is little, does not have the surging force of momentary pulse, can prolong the work-ing life of equipment and motor effectively.Needle bar impeller high speed rotating has produced spray, the bubble of a large amount of exquisitenesses under the impact of needle bar blade, tangentially the needle bar blade has got rid of again and has enriched tiny water droplet under action of centrifugal force, can both fully contact, increase and accelerated water-soluble ability of airborne oxygen and speed with air.
Stick-type impeller helix oxygen-increasing machine of the present invention, by the motor case 1., motor 2., the needle bar impeller 3., transmission shaft 4., the carrier floating drum 5., unitor 6., 7. support wait and form.Description of drawings (accompanying drawing 1 structural representation) is characterized in that 3. the needle bar impeller of oxygenating machine is that blade and central shaft by wire or rigidity strip material constitutes.The wire of blade, rigidity strip material can be straight line, forms such as ripple.The blade of rigidity strip material comprises plastic wire-drawing, and reinforced plastics wire drawing, nylon reach and is the plastics steel wire behind the anticorrosion electrostatic plastic spraying of making.The central shaft of impeller can be materials such as round steel, steel pipe, reinforced plastics pipe, sticking plaster, can also be combined into the axle of twisted shape with the wire rod wringing.The combination of axle and wire, rigidity strip blade can be welding, insertion, injection moulding, can also be wire rod, insertion blade forming when the rigid material wringing is combined into the twisted shape axle.Because of oxygenating machine is in the moist environment and saltiness height in the seawater for a long time, big to Corrosion of Metallic Materials.The material of each parts of whole oxygenating machine all is moistureproof, corrosion resistant.According to the difference of water quality, can be divided into fresh water, seawater oxygenating machine.Quantity by impeller can be divided into simply connected, duplex and multi-joint oxygenating machine.
The characteristics of stick-type impeller helix oxygen-increasing machine maximum of the present invention are: 1. the needle bar impeller can be successively contact with water body uniformly and splashes abundant fine and smooth spray, water droplet, bubble and water smoke and can fully contact with air, water greatly surperficial, and water body oxygenation amount is fast; 2. speed of rotation is fast, compares with the oxygenating machine with equipower in the unit time, has increased water displacement, has fully improved oxygenation effect and speed; 3. impeller adopts rigidity strip shape, has reduced resistance, the long-pending increase at double of the water surface that splashes on the contrary, and the dissolving that helps oxygen absorbs; 4. the integral body of impeller is leptospira structure, can promote water body laterally, vertically carrying out convective exchange, helps improving the effect of oxygenation; 5. the water droplet distance of having got rid of along needle bar impeller tangential direction is far away, has prolonged the time that water contacts with air, has accelerated dissolved oxygen speed.
Application notice
1, the strip in the water body, board can be wrapped on the needle bar impeller, influence the works better of oxygenating machine, and therefore, water body can not have strip, flaky object to flow to oxygenating machine.
2, draft can not guarantee that motor normally moves above 40mm below the electric machine stand.
3,, correctly select the type of oxygenating machine according to the water quality situation.
When 4, installing, all should there be anchor line in the four directions or adopts alternate manner to fix.
Claims (1)
1, stick-type impeller helix oxygen-increasing machine by the motor case 1., motor 2., the needle bar impeller 3., transmission shaft 4., the carrier floating drum 5., unitor 6., 7. support wait and form, 3. the needle bar impeller that it is characterized in that oxygenating machine is that blade and the central shaft by wire or rigidity strip constitutes.
