Description
The utility model belongs to the improvement of paddle aerator.
Aerator has oxygenation, stirs water, aeration three acts on greatly.The various aerators that abroad begin one's study from the fifties end are mainly used in environmental protection, waste water treatment, and it is less to be used in the aquatic products aspect.China's culture fishery brings into use aerator to have the history of more than ten years so far, and the oxygen content, the solution fish that increase the waters with various types of aerators raise the nose above water to breathe because of anoxic, thereby the phenomenon of death by suffocation had got significant effect.What quantity at most in all kinds of aerators of China's use at present, use face is the widest, oxygenation effect is best is paddle aerator, shown in figure one.Among the figure: 1, case; 2, motor; 3, reduction box; 4, impeller; 5, blade; 6, air inlet pipe; 7, floating drum; 8, pole.Electromotor 2 is by 4 rotations of gearbox impeller, and blade 5 makes pond circulation down waterborne, and the referred water surface of the water of bottom, liquid level are brought in constant renewal in, the ingress of air dissolved oxygen.Simultaneously, after impeller 4 rotation, water from impeller 4 to around throw away, form horizontal flow and get rid of back taper water curtain shape hydraulic jump to the water surface.Water curtain gets rid of to all around the time, causes water level fluctuation, makes airborne oxygen soluble in water.Be welded with several air inlet pipe 6 on the reverse taper of impeller 4, when impeller 4 rotations, air inlet pipe 6 back sides in face of water on the impeller 4 produce negative pressure, suck some air, and the air that is inhaled into mixes with the water that raises up and makes oxygen soluble in water.Although existing aerator has oxygenation, stirs water, the advantage of aeration, but owing to also there is following shortcoming in the reason in the design: 1, in order to utilize negative pressure inlet, the air inlet pipe 6 of many apertures is installed on the impeller reverse taper, these pipes are when impeller rotates, suck air on the one hand, also want consumed energy on the other hand; 2, because blade 5 is vertical with air inlet pipe 6 aspects, enter strike and pulverizing that bubble in the water can not get blade, can not fully mix with the water body of lifting; 3, because the oblique throwing of current is moving, the gas that enters in the water in the water lift process is very easily escaped in air.
The utility model is exactly the shortcoming at said apparatus, and the negative pressure inlet device that design a kind of need not be special, does not increase energy consumption, and the aerator that the negative pressure inlet effect is improved.
Feature of the present utility model is: design a kind of new negative pressure inlet device, change the hollow blade of V-type into by the single blade on original impeller, cancel original core barrel that advances; And be provided with quantity and equate with blade on circumference at the bottom of the impeller reverse taper, the position is corresponding one by one with blade, and has the rectangle deflector of certain curvature.
Accompanying drawing the 2, the 3rd, structural representation of the present utility model.Among the figure: 1, case; 2, motor; 3, reduction box; 4, impeller; 5, blade; 7, floating drum; 8, pole; 9, air admission hole; 10, deflector; 11, blade anter; 12, blade rear panel; 13, air admission hole; 14, air admission hole.Further specify the utility model below in conjunction with drawings and Examples.
Impeller 4 is made the back taper bodily form.On the bus of impeller reverse taper, be welded with 8～12 V-type hollow blades 5.V-type hollow blade 5 be by two slightly the rectangle steel plate intermittent weld of height connect and form, its space of being interrupted welding is the air admission hole 14 that blade enters the waters, and the angle of two length of a film square plates is controlled between 15 °-20 °, the effect of stirring water and oxygenation like this is best.A high block length square plate is an anter 11, and its base all is welded on the reverse taper bus; A short block length square plate is a rear panel 12, and its base and reverse taper bus are at a distance of the 1-2mm distance, and the interruption welding, in case the distortion of uppermost leaf sheet, discontinuities also becomes the air admission hole 13 that blade enters the waters simultaneously.For the water effect is stirred in raising, two ends at V-type hollow blade 5 can be sealed with two triangle steel plate welding, also the two ends of two block plates directly can be welded, as long as making it seals, with the hollow corresponding reverse taper bus of blade 5 on also be drilled with several air admission holes 9, for the effect that guarantees to stir water, blade 5 is made long and short two kinds, and alternate being welded on the back taper bus.When impeller 4 rotated in the waters, the anter 11 of V-type air blades 5 was a zone of positive pressure, and rear panel 12 and top are negative pressuren zones.So air admission hole 13,14 all can air inlet in the waters.Promptly all slits can suck, under the situation that does not increase energy consumption, the air inlet effect is improved greatly, has saved the pipe 6 that is specifically designed to negative pressure inlet again.Simultaneously.Front vane 11 enters strike, the pulverizing through rear blade 12 of the bubble that produces in the waters, increased the aqueous vapor contact area, quicken the dissolving of oxygen in water, and overcome original aerator blade and airintake direction is inconsistent, the gas that enters can not obtain blade the low shortcoming of effective pulverizing, dissolved efficiency.
In addition, for the hydraulic jump that remedies former aerator water curtain shape is freely got rid of shortcoming to the water surface, the utility model has also designed a kind of guiding device, quantity on the circumference equates with blade at the bottom of the reverse taper by being welded on, the position is corresponding one by one with blade 5, and has the deflector 10 of certain curvature to finish.Deflector 10 can be a light material, also can be other substitute.Its effect is that the water of forcing to elevate is not upward throwing, but downward oblique fire water.Owing to shortened the time that water curtain moves in air, therefore help reducing the escape of bubble in the water curtain, form downwards jet in addition during oblique fire water, effect is entrainmented in generation, promptly entrainment air and enter water body, and water body is produced strong impact, cause the stirring of water fluctuation and swallow, this all helps airborne oxygen and is dissolved in water.
Paddle aerator according to the utility model is made has distinguishing feature efficient, energy-conservation and that oxygen transfer rate is strong. Take 1.5 kilowatts impeller enhanced machines as example, by test, performance indications are considerably beyond ministry standard, and its dynamic efficiency surpasses 2.3kg02/kwh, is 1.6 times of the standard laid down by the ministries or commissions of the Central Government; Oxygen transfer rate surpasses 3.4kg02/h. Increase the oxygen of equivalent amount in the waters, energy consumption can reduce more than 40% at least. It is the oxygen increasing equipment of high density sea, freshwater aquaculture industry indispensability.
