Abstract
The utility model relates to a casual flow type aerator which utilizes the air current turbulence theory to generate a few bubbles. The aerator comprises an intake chamber, a conduction current support, a casual flow shield and a check valve ball. The conduction current support and the casual flow shield consisting of three tiers of the upper, the middle and the lower with different diameters are in turn arranged on the intake chamber, and a check valve ball is arranged between the intake chamber and the conduction current support. The air current firstly impacts the check valve ball via the intake chamber fixed on the intake tube. By the action of the pneumatic, the check valve ball floats and rotates on the intake chamber so that air can fully mix with water and the flowed air current is even. When the air current is stopped, the check valve ball is enclosed on the intake port of the intake chamber by the action of the self-weight, avoiding the floats in the aerator flowing backward and depositing. Compared with the prior art, the utility model has advantages of small resistance, uniform gas distribution, little thin bubble, high filling oxygen rate and without blocking.
Description
Technical field
The utility model relates to the oxygen supply distribution device that a kind of biological treatment of sewage is used, particularly a kind of turbulent flow type aerator that utilizes the turbulent air flow principle to produce the pettiness bubble.
Background technology
The aerator of treatment unit is the most key parts in sewage biological treatment technique at present, and its quality directly affects wastewater treatment efficiency and the height of device working cost and the job run effect of device of device.Because the kind difference of aerator, the effect that Xiang Shuizhong fills oxygen are also different.At present the aerator that uses mainly contains two kinds: a kind of is big or middle bubble aeration devices such as perforated pipe, Kingsoft type, turbulent flow type, though they have velocity flow pattern preferably, because its bubble diameter is big, the gas-liquid area that contacts is little, so coefficient of oxygen utilization is low; Second kind is the micro-hole aerator that resembles bell jar type, dome-type structure, and it is abundant good dispersity when oxygen supply, and the gas-liquid mixed contact surface is big, oxygen supply effect height.But because long-time aeration uses, the gas distribution face is sedimentary clay shape thing and the outgassing micropore of gas distribution face is stopped up gradually, and the aerator drag losses is strengthened, and energy consumption raises, and aeration oxygen supply effect descends.The applicant has once announced notification number on the patent gazette of State Intellectual Property Office's issue on July 16th, 2003 be CN2532076, name is called the utility model patent of " power air diffusion aerator ", it is with gas process impeller, three cuttings of falling umbrella shape, being with the diffusing stream cover of conical insert, segment bubble, improved the utilization ratio of oxygen and the mass-transfer efficiency of oxygen.But when stopping aeration, floating outstanding thing is back in the inlet pipe easily, causes air inlet obstruction, intake efficiency not high.
The utility model content
The purpose of the utility model is to provide that a kind of gas distribution is even, oxygen-transfer efficiency is high, the power turbulent flow type aerator that uses or be difficult for when inactive taking place stopping up.
For realizing above-mentioned purpose, the technical solution of the utility model is such: it comprises inlet plenum, be contained in the water conservancy diversion support on the inlet plenum successively and have the upper, middle and lower-ranking of different diameter to fall the umbrella shape stream cover that looses, the non-return that is contained between inlet plenum and the water conservancy diversion support is shunted ball; The water conservancy diversion support is by screw rod, nut and the three layers of stream cover combination assembling of loosing, and inlet plenum is provided with hickey and is connected with inlet pipe.Three layers are fallen the loose periphery of stream cover of umbrella shape is the sawtooth tooth, wherein goes up the conical insert that distributing on the stream cover cover wall that looses, and its effect is cutting, dispersion air bubble, stirs water body.
Its principle of work is such: air communication is crossed the inlet plenum that is fixed on the inlet pipe and is impacted non-return shunting ball earlier; Because air operated effect, the rotation that on inlet plenum, suspends of non-return shunting ball, make the air water thorough mixing, it is even to go out entraining air stream, again through three layers of band saw teeth fall umbrella shape loose the stream cover and on conical insert cutting bubble, disadvantages such as thereby improved the utilization ratio of oxygen and the mass-transfer efficiency of oxygen in the air greatly, the hole that has changed traditional aeration is diffused as power collision diffusion, and the resistance that has overcome micropore hole aeration is big, easily stop up, energy consumption is many.When air-flow stopped air inlet, non-return shunting ball was under the effect of conducting oneself with dignity, and involution deposits thereby avoided the interior floating outstanding thing of aerator to flow backwards on the inlet mouth of inlet plenum.It is compared with existing technology, has the macropore exhaust, resistance is little, gas distribution is even, bubble is tiny, oxygenation rate height, do not stop up, exempt from cleaning, long service life, stable, low cost and other advantages.
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Description of drawings
Fig. 1 is the utility model assembling synoptic diagram.
Embodiment
Referring to shown in Figure 1, power turbulent flow type aerator is by inlet plenum 1, is contained in water conservancy diversion support 3 on the inlet plenum 1 and three layers of different upper, middle and lower of diameter and falls loose stream cover 4,5,6 and place non-return shunting ball 2 compositions between water conservancy diversion support 3 and the inlet plenum 1 of umbrella shape.Wherein upper reversed-umbrella hood shape loose stream cover 6 and in fall the umbrella shape stream cover 5 that looses and be provided with leg, leg is linked in next and falls the umbrella shape stream cover that looses and go up and form the certain clearance distance; Three layers of loose stream cover 4,5,6 and water conservancy diversion support 3 are by being applied in bolt 7, packing ring 8, the nut 9 combination assemblings on its axis hole.Inlet plenum 1 is bowl-shape shape, and its bottom is provided with the threaded air inlet mouth of pipe, fixes with the inlet pipe screw thread; Non-return shunting ball 2 is when airless, and lucky involution is on the air inlet mouth of pipe under the effect of deadweight.The periphery of the diffusing stream cover 4,5,6 of the umbrella shape of falling is provided with and is the sawtooth tooth, its diameter increases from the bottom to the top layer successively, go up the conical insert 6a that distributing on the stream cover 6 cover walls that loose, the bubble that diffuses out from non-return shunting ball 2 through the stream cover 4 that looses down, loose after stream covers 5 cutting, pass through the repeatedly cutting of conical insert 6a with the sawtooth tooth of periphery of diffusing stream cover 6 again, form tiny and uniform bubble, thereby improved the utilization ratio of oxygen.
