Of the present utility model being achieved in that
The utility model is based on the ultramicropore aerating apparatus of aeration and plug-flow integrated optimization, the output shaft of underwater propeller (1) is connected with impeller (3), hollow aeration plate (4) is fixed on the underwater propeller (1) and is positioned between underwater propeller (1) clutch end and the impeller, aeration plate (4) side has inlet mouth (7) to be connected with air compressor, and aeration plate is evenly equipped with some aeration producers (5) by impeller (3) one side rings on week.
Have guide shell (2) to be connected with an end of underwater propeller (1), impeller (3) and aeration plate (4) are positioned at guide shell (2).
Aeration producer (5) has shell (10), the one end is connected with aeration plate (4), there is rubber pad (11) to be connected in the shell (10) with porous plate (14), rubber pad (11) is sealed the passage of the logical aeration plate inner chamber of this end, porous plate (14) and shell (10) inner chamber are movingly, shell (10) the other end is equipped with microwell plate (13), has bung flange (12) to be connected and to limit the position of microwell plate (13) with shell, between microwell plate (13) and porous plate (14) pressure spring (15) is arranged.
One end of shell (10) has outside screw to cooperate with internal thread hole on the aeration plate (4), and rubber pad (11) is fastening by bolt (16) with porous plate (14), and microwell plate (13) is the vertical overlapping placement microwell plate of multilayer.
Aeration plate (4) has 4 boss (9) to be distributed on the outside of disk body (6), by bolt aeration plate (4) is fixed on the underwater propeller (1), is evenly equipped with 6 screws (8) on the card of aeration plate (4) and is threaded with aeration producer (5).
Underwater propeller (1) is a motor, and the axis of the axis of aeration producer (5) and impeller (3) acutangulates angle.
The utility model has following actively useful effect:
(1) this ultramicropore aeration belongs to dynamic aeration, gas comes out through the stirring of impeller from the aeration producer, form a kind of helical flow of high-speed motion with liquid, make mud, water, gas three-phase thorough mixing, realize integrating aeration, plug-flow, the multi-functional high efficient aeration mode of stirring.
(2) gas through the stirring of impeller, forms the proal bubble of rotation after the ejection of aeration producer, gas is moved ahead in the horizontal direction apart from elongated, enlarge the aeration scope, increased the residence time of gas in water, effectively improved the transfer efficiency of oxygen.
(3) behind the impeller of gas through rotation, can be smashed by impeller and form the littler bubble of particulate, so just can increase the contact area of gas and water greatly, more help the transfer of oxygen.
(4) in traditional aeration mode, bubble is easy to form bigger gas bag because of the collision contact polymerization of bubble in uphill process, be unfavorable for the transfer of oxygen, and in this structure, after gas stirs through impeller, in the process that travels forward at a high speed, can form the hangover bubble of tadpole shape, this hangover bubble is not easy just to have increased the contact area of gas and water so virtually because of the collision contact aggregates into bigger bubble, has improved aeration efficient.
(5) the aeration producer is offset certain angle on the impeller sense of rotation, and when aeration, the gas of ejection can be given the acceleration of current that enters impeller like this, and energy-conservation effect has been played in the load that alleviates motor.
(6) the aeration producer has good Visible Counterflow performance, is difficult for stopping up.
(7) oxygenation capacity of this ultramicropore aeration is easy to regulate, and can adapt to the variation of oxygen requirement neatly.
(8) can cutting down the consumption of energy greatly of this ultramicropore aeration saved cost of sewage disposal.
(9) this ultramicropore aerating apparatus carries out aeration and plug-flow simultaneously when work, and when oxygen content is enough in the oxidation ditch, but close compressor stops aeration, only moves motor and carries out plug-flow under water, has both realized the optimization running of oxidation ditch, has saved energy consumption again.
Description of drawings:
Fig. 1 is the structure iron of the integrated ultramicropore aerating apparatus of aeration and plug-flow.
Fig. 2 is the outer side view of aeration plate.
Fig. 3 is the installation of A-A sectional view and the aeration producer of Fig. 2.
Fig. 4 is the structural representation of aeration producer.
Embodiment:
With reference to Fig. 1, the utility model is a kind of energy-efficient aeration and oxygenation for sewage device.Aeration plate 4 is fixed on the underwater propeller 1, aeration plate 4 has been installed six aeration producers 5 by being evenly distributed on the circumference of impeller 3 one sides, source of the gas is provided by air compressor, with plastic hose air compressor is linked to each other with the inlet mouth 7 of aeration plate 4, and gas diffuses out by aeration producer 5.3 rotations of underwater propeller 1 impeller, gas carries out the gas-liquid thorough mixing under the brute force of impeller 3 stirs, and mixed solution is radial powerfully to ejection all around from the discharge opening of guide shell 2 again.When aeration rate increases, can accelerate the rotating speed of impeller 3, gas is carried out more effective pulverizing, improve aeration efficient; When aeration rate diminished, the rotating speed of the impeller 3 that can slow down guaranteed that on the one hand motor can overcurrent, can save energy consumption on the one hand.And when dissolved oxygen content is enough in the oxidation ditch, can stop aeration, only allow motor 1 running realize plug-flow effect to oxidation ditch further having reduced energy consumption.
