Flood dragon highly effective oxygen dissolving instrument
Technical field:
The present invention relates to a kind of flood dragon highly effective oxygen dissolving instrument, use when being particularly well-suited to biochemical sewage oxygenation.
Background technology:
The structures such as current biochemical sewage oxygenating system many employings conventional microporous aeration and mechamical xurface aeration, traditional micro-pore aeration system dissolved oxygen effectiveness comparison is good, but the defect such as device structure is complicated, maintenance is inconvenient, investment is big and floor space is big; Mechamical xurface aeration relies on the wheel on the water surface and rotates, and produces negative pressure, sucks air, reaches to hold the purpose of oxygen, but there is structure complexity, and maintenance is inconvenient, investment is big again, the problems such as noise is serious.
Summary of the invention:
The task of the present invention be a kind of simple in construction is proposed, convenient to install and maintain, oxygen-transfer efficiency is high, the flood dragon highly effective oxygen dissolving instrument that energy consumption is little.
The task of the present invention so completes, flood dragon highly effective oxygen dissolving instrument, it is characterized in that: whirlpool high-pressure pump is connected with the air inlet arranged on beam barrel by soft air pipe, described beam barrel one end is positioned at more than the water surface and associated electric motor and fixes, in beam barrel, radial position is equipped with quill shaft, quill shaft one end waterborne is connected with motor shaft by universal joint, the other end of quill shaft is positioned at and is equipped with impeller by water lubriucated bearing under water, below impeller, hollow the tip of the axis is provided with nebulizer, and the axle body of described quill shaft is provided with air inlet. Described air inlet is arranged on the side of beam barrel, the quantity of described air inlet more than at least two. Described motor, beam barrel and quill shaft are to tilt to be fixed on the crossbeam of more than the water surface, and angle of inclination is 30 °-60. The soft air pipe that the described gases at high pressure in whirlpool high-pressure pump are connected by beam barrel side enters inside beam barrel, and the outlet that gases at high pressure are introduced in inner chamber on the nebulizer being connected by quill shaft end under tiltedly by the air inlet that institute's quill shaft is arranged communicates with waters. Described impeller has at least two panels propeller blade, and what described universal joint adopted is candan universal joint.
The present invention has the effect that the blade of the underwater turbine that the technical program relates to adopts the paddle shape blade of propeller, add special nebulizer, drastically increase dissolved oxygen efficiency, not only dissolved oxygen is effective, and power consumption is low, dissolved oxygen meter can tilt to install, and also waters is carried out plug-flow while dissolved oxygen, making waters to circulate, dissolved oxygen efficiency is higher.This dissolved oxygen meter adopts water lubriucated bearing under water, and noise is low, easy for installation, it is simple to safeguard, and simple in construction, power consumption is low, long service life, and equipment is safeguarded in the keeping being suitable for the water treatment facilities such as oxidation ditch, common aeration, river course.

Detailed description of the invention:
Fig. 1 is with flood dragon highly effective oxygen dissolving instrument shown by structure chart mode, having of this dissolved oxygen meter installation waterborne: 1, whirlpool high-pressure pump, 2, soft air pipe, 3, air inlet and motor 4, furtherly: whirlpool high-pressure pump is connected with air inlet 3 by soft air pipe 2, described air inlet 3 is arranged on a side of beam barrel, one end of beam barrel is positioned at more than the water surface, its other end is positioned at below the water surface, one end waterborne of (arrow show the water surface) beam barrel 6 and motor 4 are connected and fix, it is provided with below this dissolved oxygen meter water surface: quill shaft 7, air inlet 8, bearing 9, impeller 10 and nebulizer 11, can show from Fig. 1, quill shaft 7 is that radially loading fits over the inside of beam barrel 6 and is connected to impeller 10 by water lubrication plane bearing, hollow the tip of the axis is provided with nebulizer 11, described quill shaft is provided with air inlet 8, air inlet is communicated with waters by the cavity of quill shaft, described air inlet quantity more than at least two, can up and down Heterogeneous Permutation on the axle body of quill shaft, the other end of quill shaft 7 is connected with the motor shaft on motor 4 waterborne by universal joint. described bearing is the novel water lubriucated bearing adopted, it is form with zirconium oxide axle sleeve and polytrimethylene ether axle sleeve, described impeller 10 is at least made up of 2 propeller blade sheets, what described universal joint 5 adopted is candan universal joint, described motor 4, beam barrel 6, adjustable between quill shaft 7 and the angle 30 °-60 ° of horizontal plane, this dissolved oxygen meter is to tilt to install, whirlpool high-pressure pump and soft air pipe can be arranged on pool wall during installation, on crossbeam, best position is that this dissolved oxygen meter is in and to be installed by the middle of the sewage of oxygenation, thus improving appearance oxygen efficiency.
The air path of dissolved oxygen meter is from whirlpool high-pressure pump 1, pressure-air in whirlpool high-pressure pump enters inside beam barrel by the air inlet 3 of soft air pipe 2 and beam barrel 6 side, being entered in quill shaft inner chamber by the air inlet 8 on quill shaft 7 by pressure-air, the outlet on nebulizer 11 being connected by quill shaft end under tiltedly is communicated with waters.
During work, motor 4 main shaft drives quill shaft 7, quill shaft impeller 10 and nebulizer 11 high speed rotating by universal joint 5, promotes waters flow forward, forms high speed rotating whirlpool with atomizer exit Its Adjacent Waters before impeller. Being broken down into micro-bubble from atomizer exit air out under the effect of this whirlpool, improve the specific area of unit volume air, minute bubbles travel forward along with current, and slowly emerge. Longer from minute bubbles this process time that produces to emerge, so energy of oxidation is well dissolved in water in bubble, thus reaching good dissolved oxygen effect. Furthermore, dissolved oxygen meter is inclined and mounted in water, has very strong plug-flow effect, is conducive to large-area waters to circulate, it is to avoid the generation at dead angle, can meet pulling flow type dissolved oxygen requirement, is particularly suitable for plug-flow and the dissolved oxygen of oxidation ditch; This dissolved oxygen meter according to the requirement of the height of pond middle water level and plug-flow, can adopt different setting angles, wherein with 30 ° of-60 ° of the bests, can more embody powerful plug-flow effect in this angular range, hold oxygen efficiency more efficient.
