Description
Technical field
The present invention relates to a kind of aeration oxygenator, belong to technical field of sewage in environment protection.
Background technology
Aeration refers to artificially and passes into air by suitable equipment in biochemical aeration tank, to reach the purpose that improves dissolved oxygen in waste water.Aeration not only makes liquid-to-air contact oxygenation in pond, and, due to agitated liquid, has accelerated oxygen in air and shifted in liquid, thereby completes the purpose of oxygenation; In addition, aeration prevents that pond inner suspension body from sinking in addition, strengthens the purpose that in pond, organism contacts with dissolved oxygen with microorganism, thereby guarantees in pond there be under the condition of sufficient dissolved oxygen microorganism, to organic oxygenolysis in sewage.
Aerating apparatus refers in waste water activated sludge process water treatment procedure the equipment to the aeration tank oxygen supply.The quality of aerating apparatus, not only affect the sewage Biochemical Treatment, and directly have influence on a processing occupation of land, investment and working cost.
Aerating apparatus commonly used has vertical surface aeration machine, and its mechanical transmission structure is roughly the same, and all with aeration impeller, the key distinction is on the structure formation of aeration impeller that pump type impeller, inversed umbrella type, K3 type impeller, plate impeller etc. are arranged.Its fixed form has two kinds of fixed and Float cylinder types, wherein fixedly take pump type and inversed umbrella type impeller as main, and Float cylinder type is arranged on floating drum, with steel cable, is fixed in water, with water-proof cable, is attached thereto, and it can move as required within the specific limits.All vertical surface aeration machines all rely on impeller in effect, bigcatkin willow to be risen, and form droplet, and the globule contacts with air, this castering action relies on impeller power fully, and oxygenation capacity changes greatly with impeller diameter, but impeller is larger, institute's consumption of power is also larger, and power loss is large, and energy consumption is high.
Summary of the invention
The objective of the invention is, for overcoming the deficiencies in the prior art, provides the aerating apparatus that a kind of power loss is little, efficiency is high.
The technical solution used in the present invention is: comprise two upper and lower parallel and coaxial disks, the be fixedly connected axle center place of two disks of axle, the upper end of axle is fixedly connected with electric motor, circumferential direction along the card of two disks evenly is fixed with several bend pipes, each bend pipe forms by the straight tube of hypomere and the bending tube of epimere, the straight tube of the hypomere of each bend pipe is all parallel with axle and stretch out first disk of bottom downwards, on superposed second disk of the bending tube of the epimere of each bend pipe, the bending tube of the epimere of several bend pipes is all outwardly-bent towards oblique upper radially along the center of second disk, each bend pipe upper end all has one section trunnion, the side of trunnion is provided with perpendicular to the outward extending kapillary of trunnion, kapillary communicates with extraneous air, first disk of bottom and the bend pipe of its underpart all are placed in treatment sewage.
Further, the angle of bend of the bending tube of the epimere of several bend pipes is 90 ° ~ 150 °, and the angle of bend of all bending tubes is identical or different.
The present invention has the following advantages after adopting technique scheme: (1) consumes energy low, and disk is done little as possible, as long as can meet the bend pipe erection space, to reduce, stirs the water yield, reduces power waste; (2) submersion depth is darker, and along with the bend pipe lower end increases, the water at the bottom of pond can be drunk up oxygenation, has increased the degree of mixing of waste water in the pond; (3) trunnion can make current accelerate, and the negative pressure formed at the trunnion place increases, and the kapillary at trunnion place can suck more air, can be effectively and the current mixing, and the increase dissolved efficiency.(4) the small gas column that kapillary forms is more conducive to dissolve; (5) trunnion accelerates current, and water is the spurting ejection, forms more droplet, with air, contacts fully, and oxidation effect is better.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of aerating apparatus of the present invention;
Fig. 2 is the local enlarged diagram of bend pipe and disc set assembling structure in Fig. 1;
In figure: 1. disk; 2. axle; 3. bend pipe; 4. trunnion; 5. kapillary; 6. electric motor.
Embodiment
With reference to Fig. 1, the present invention includes 1, two disk 1 of two upper and lower parallel and coaxial disks and place up and down, there is identical axial line, be fixedly linked in the place, axle center of two disks 1 by axle 2 simultaneously.The place, axle center of first disk 1 of bottom is fixed in the lower end of axle 2, and the upper end of axle 2 is passed second disk 1 on top and extended upward certain length, and the upper end of axle 2 is fixedly connected with electric motor 6, by electric motor 6, drives two disks 1 coaxial rotating simultaneously.
Refer again to Fig. 2, circumferential direction along the card of two disks 1 is evenly fixed a circle bend pipe 3, bend pipe 3 has several, several bend pipes 3 pass the card of two disks 1 simultaneously, each bend pipe 3 forms by the bending tube of the straight tube of hypomere and epimere, the straight tube of the hypomere of each bend pipe 3 all and first disk 1 of stretching out bottom parallel with axle 2 to downward-extension.On superposed second disk 1 of the bending tube of the epimere of each bend pipe 3, the bending tube of the epimere of several bend pipes 3 all has certain angle a along the center of second disk 1 towards oblique upper radially is outwardly-bent, and angle of bend a is between 90 ° ~ 150 °.The angle of bend a of the bending tube of all bend pipes 3 can be identical, also can be different.
Each bend pipe 3 upper end all has one section trunnion 4 that diameter is thinner, and trunnion 4 the thinnest sides partly are provided with kapillary 5, and kapillary 5 tube walls stretch out perpendicular to trunnion 4, and kapillary 5 communicates with extraneous air.
When the present invention works, the bend pipe 3 of first disk 1 and its underpart all is placed in the pond for the treatment of sewage, at the bottom of the bend pipe mouth of bend pipe 3 bottoms is positioned at sewage lagoon, by electric motor 6 band moving axis 2, rotated, axle 2 drives two disks 1 and is fixed on two bend pipes 3 on disk 1 and rotates together, bend pipe 3 tops can form negative pressure, water can be drunk up and be thrown away by gas pressure, along with water is thrown out of, the interior formation negative pressure of bend pipe 3, water is drunk up and is thrown out of continuously by bend pipe mouth at the bottom of pond, when water process trunnion 4, trunnion 4 accelerates current and produces negative pressure in pipe, air is inhaled into mixing by kapillary 5, be thrown out of again the formation two-pass aerating.
