Abstract
The utility model relates to a combined flow diffusing aerator which relates to oxygen replenishing equipment for biochemical sewage treatment. The utility model is characterized in that the utility model comprises a flange, a pipe sleeve, flow diffusing covers, a nozzle and an air pipe, and the air pipe passes through the central circular hole of the flow diffusing covers; the flow diffusing covers are positioned at a pipe sleeve support of the air pipe, and the nozzle is arranged at the lower part of the air pipe; the radial direction on theflow diffusing cover is provided with a flow guiding plate which is evenly distributed with a plurality of small holes; the lower part of the nozzle is provided with a supporting leg which is fixed at the tank bottom. Due to the adoption of the flow diffusing covers, the utility model improves the oxygenation performance of the aerator, 20 percent of energy is saved, and the service life is extended by 2-3 times.
Description
The utility model belongs to the C02F1/00 field, relates to the oxygen replenishing equipment in a kind of sewage biochemical treatment.
Air diffusion aerator has good processing, cost is low, and advantages such as good installations have been widely used in the sewage air blast biochemical aerator device, but air passes through air diffusion aerator, and after cutting twice, bubble is bigger, and the utilization ratio of oxygen is on the low side, thereby energy consumption is bigger; The present air diffusion aerator in aspect all is fixed in addition, accounts for volume, and inconvenience is carried, dismantled, and is suspended under the arm, and easily vibrations damage, so work-ing life is low.
The purpose of this utility model provide a kind of have energy-conservation, oxygenation capacity good, simple structure, quick detachable, that productive expense is low, transportation is repaired is convenient, the built-up type air diffusion aerator of long service life.
The utility model takes following scheme to realize: the built-up type air diffusion aerator is characterized in that: comprise flange, pipe box, loose and flow cover, nozzle, ventpipe; Ventpipe passes the center hole of the stream cover that looses, and the stream cover that looses is by the pipe box supporting that is positioned at ventpipe, and the ventpipe bottom is furnished with nozzle.In addition, on the stream cover that looses, radially be provided with flow deflector, and several apertures of uniform distribution, and be provided with supporting leg in the bottom of nozzle.
The utility model is owing to pass a plurality of diffusing stream covers on ventpipe, the stream cover number of loosing can suitably be set as the case may be, because the increase of cutting number of times, make water boundling bubble, at first pass nozzle after peripheral sawtooth once cuts, at the continuous multi-stage cutting and crushing of the stream cover that looses through each by ventpipe, increased the contact area of gas-liquid, thereby improved the utilization ratio of oxygen effectively, improved the oxygenation capacity of aerator, thereby reduced energy consumption.In addition, the nozzle of this aerator is thicker, and airiness is unobstructed, and resistance is little, is difficult for stopping up, and fixes at the bottom of the nozzle bottom is provided with supporting leg and pond, and is shockproof sturdy and durable, thereby long service life.
Advantage of the present utility model is as follows:
1. diffusing stream cover of the present utility model can a plurality of arbitrary combination form, and can select suitable number as the case may be for use, and the cutting number of times increases, and has improved the oxygenation capacity of aerator, thereby than existing aerator energy-conservation 20%.
2. the utility model can disintegrate fixed changing into, just Zu Zhuan aerator.Can according to circumstances be assembled into and three cut, four cut or more cutting type aerator.The assembly of this aerator is convenient to process, carry, install, dismantle, and has reduced cost of use.
3. the utility model is fixed at the bottom of the bottom of nozzle is provided with supporting leg and pond, and is shockproof sturdy and durable, and prolong 2-3 doubly than existing aerator work-ing life.
Below in conjunction with accompanying drawing the utility model is described in further details:
Fig. 1 is plan structure figure of the present utility model
Fig. 2 is main TV structure figure of the present utility model
The built-up type air diffusion aerator as shown in Figure 2, comprise and send out blue 1, ventpipe 7, pipe box 2, stream cover 3 looses, nozzle 4, supporting leg 6, flow deflector 8, aperture 9, above-mentioned each parts are injection molded by highstrenghtpiston ABS, also can or nonmetally process with metal as glass reinforced plastic, the stream that looses covers on 3 flat boards and radially has stiffening web flow deflector 8, periphery about 120 sawtooth that all distribute, and the several holes that the last uniform distribution diameter of stream cover that looses is ∮ 1mm is little by 9, play air cutting shunting action, the diffusing stream cover diameter that ventpipe 7 tops are passed is ∮ 600mm, down be followed successively by ∮ 400mm, ∮ 200mm, the cover distance is 100mm, each looses and to be separated mutually by pipe box 2 supportings between the stream cover, and nozzle 4 diameters are ∮ 120mm, its underpart about 30 sawtooth that all distribute.To have the DN32pg10 standard and send out that blue ventpipe 7 bottoms are threaded to penetrate the 1st pipe box 2 earlier, penetrating diameter again is the diffusing stream cover 3 of ∮ 600mm, penetrate second pipe box 2 then, diffusing stream cover that to penetrate diameter successively and be the diffusing stream cover 3 of ∮ 400mm, the 3rd pipe box 2, diameter be ∮ 200m 3, the 4th pipe box 2, nozzle 4, fastening by M32 nut 10 at last, in nozzle 4 bottoms two bore dias being set is ∮ 12mm, the supporting leg 6 that 100MM is long is by being bolted on the nozzle 4, at the bottom of supporting leg 6 bottoms and the pond by ground leg bolting.Working conditions: the depth of water is 3-8 rice, and air quantity is 30M
3/ h.
