Abstract
The utility model relates to a propeller water flow oxygen increase machine, belonging to water flow oxygen increase machinery used for aquaculture. The utility model is provided to overcome the disadvantages of poor oxygen increase effects, greater noise, complex structure, etc. of the existing oxygen increase machine. The propeller water flow oxygen increase machine is formed by assembling a power device, a drive shaft, a propeller, etc. A gas nozzle and a guiding tube are also included to make the air ejected from the air outlet of a hollow drive shaft and the jet aperture of an air nozzle cut by propeller blades rotated at high-speed and water pressure to form subtle air-bubbles to be dissolved in water. The utility model which is excellent oxygen increase machinery in the aquaculture has the advantages of good oxygen increase effect, simple structure, lighter weight and less noise.
Description
The utility model is the propeller flow oxygenating machine, belongs to the used for aquiculture aerator.It has a tubular shaft, has into and out of pore on the axle, and water screw is equipped with in the tubular shaft lower end, and the upper end connects with shaft coupling with as the electric motor of power or diesel engine.
For output and the quality that improves aquaculture, prevent that the product of culturing are dead because of anoxic, need with oxygenating machine oxygenation to keep culturing certain dissolved oxygen amount in the pond.At present the oxygenating machine major part that adopts of home and abroad is water to be splash with air contact, and with expansion liquid, gas contact interface, reaching the oxygenation purpose, but oxygenation effect is undesirable, and weight is bigger, and noise is also bigger.Developed the air-breathing oxygenating machine of water screw in recent years abroad, propeller flow machine as Japan's " breed " magazine 1987 the 10th phases, 87 pages of introductions, the air-breathing oxygenating machine of water screw of 1988 the 4th phases, 52 pages of introductions, owing to do not utilize water screw blade back place negative pressure, can not give full play to the air-breathing oxygenation effect of water screw.
The utility model purpose is in order to overcome above-mentioned shortcoming, proposes a kind ofly can utilize water screw blade back place negative pressure, improves oxygenation effect, and simple in structure, weight is lighter, the propeller flow oxygenating machine that noise is less.
The utility model is realized with following two schemes:
The first string of the utility model propeller flow oxygenating machine is: a tubular shaft is arranged, have on the axle, production well, water screw is equipped with in the tubular shaft lower end, the upper end connects with electric motor as power with shaft coupling, tubular shaft is supported in the cannulated sleeve with bearing, the cannulated sleeve upper end is fixed on the motor casing, gas ejector pipe is equipped with in the lower end, gas ejector pipe is pressed close to water screw blade back place, water screw and gas ejector pipe are peripherally equipped with thrust-augmenting nozzle, are fixed on the cannulated sleeve outside, gas ejector pipe with support, tubular shaft all communicates with the cannulated sleeve inner chamber, cannulated sleeve surfaces and partly has air inlet port, and cannulated sleeve is connected in floating drum.Water screw is under the drive of electric motor, rotate in the water high speed, produce negative pressure at water screw blade back and the place ahead thereof, make air import the cannulated sleeve inner chamber from the cannulated sleeve air inlet port, in the ejection of blade back place, a part of air admission tubular shaft sprays from the tubular shaft production well a part of air along gas ejector pipe, the air of ejection is become micro bubble by the screw blade of high speed rotating with the hydraulic pressure shear extrusion and soluble in water, thereby has improved this partly intravital dissolved oxygen amount of water.Simultaneously because the end thrust that produced of water screw high speed rotating, this partly water containing high dissolved oxygen body push water screw the place ahead rapidly to, and the water body of the low dissolved oxygen of rear propeller constantly replenishes into and is inflated oxygenation.Because water screw pushes away water and advances, impel Chi Shui to flow, make waterborne oxygen-rich layer enter lower floor, acceleration gas mixes with water, like this through after a while, just can reach whole breed pond oxygenation purpose.
The thrust-augmenting nozzle of water screw and gas ejector pipe periphery is the sleeve pipe of an airfoil type section, and the effect of thrust-augmenting nozzle is the flow velocity that has increased the preceding water of water screw, has increased the negative pressure in water screw blade back place and oar the place ahead, thereby has improved inspiratory capacity.
The gas ejector pipe at water screw blade back place is shaped as the circle that pipe curves, and some jet apertures are arranged in the above.Spray by jet aperture from the cannulated sleeve inhaled air.
The utility model advantage is an oxygenation efficient height, and Chi Shui is flowed, and gas, water mixing velocity are fast, and diffusingsurface is big; Integral drive, simple in structure, weight is lighter, and noise is less.
Fig. 1 is the example structure figure of the utility model propeller flow oxygenating machine first scheme, wherein:
(1) be electric motor, (2) are shaft couplings, and (3) are tubular shafts, and (4) are water screws, (5) be gas ejector pipe, (6) are bearings, and (7) are cannulated sleeves, and (8) are thrust-augmenting nozzles, (9) be floating drum, (10) are the cannulated sleeve air inlet ports, and (11) are the tubular shaft air inlet ports.
The alternative plan of the utility model propeller flow oxygenating machine is: use submersible machine instead and replace land type motor, there is a nose cone to be contained on the submersible machine, water screw is contained on the submersible machine projecting shaft, and gas ejector pipe is contained on the nose cone, and water screw and gas ejector pipe are peripherally equipped with thrust-augmenting nozzle; Submersible machine, thrust-augmenting nozzle, inlet pipe all are fixed on the support, and gas ejector pipe, inlet pipe all communicate with the nose cone inner chamber; The inlet pipe the other end surfaces and communicates with atmosphere, and gas ejector pipe is pressed close to water screw blade back place, and support is connected with floating drum.This scheme is compared with first scheme, and the oxygenation principle is identical, just adopts submersible machine to be used as power, and drives the water screw high speed rotating, and the blade back place produces very high negative pressure, by inlet pipe air is sucked in the water.Under the water screw effect of high speed rotating, make the inhaled air atomizing, the current of generation gas-vapor mix soluble in water under water screw advances, make water movement, diffusion, acceleration gas mixes with water, increases dissolved oxygen amount.Difference is that structure is simpler, can produce the horizontal direction current, arbitrarily the degree of depth of adjusting screw oar current oxygenating machine in water.
The nose cone of this propeller flow oxygenating machine is the reducing pipe shape.
The advantage of this programme is simple in structure, and weight is lighter, oxygenation efficient height, and noise is little, and can be adjusted in the degree of depth in the water arbitrarily.
Fig. 2 is the utility model alternative plan example structure figure. Wherein:
(1) be submersible motor, (2) are radome fairing and air inlet pipe, and (3) are air jet pipes, and (4) are screws, and (5) are mozzles, and (6) are supports, and (7) are air inlet pipe, and (8) are floating drums.
