[embodiment]
Below by specific embodiment, by reference to the accompanying drawings the utility model is described further, following embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.
Embodiment 1
As Figure 1 and Figure 4, the aerating apparatus of biological reaction tank, comprise pond body, position apart from pond body bottom below 1 meter is provided with the DN80 aeration supervisor of an annular along pond body inwall, aeration supervisor be communicated with the air standpipe of blower export by DN110, in connection, use joint flange to fix, so that the oxygen that in pond, microbial metabolism needs to be provided.
As shown in Figure 2, air standpipe is fixed by air riser cradle and pond body, concrete syndeton is: air standpipe is connected by reducing tee with annular aeration supervisor, the upper hoop of aeration supervisor has anchor ear, the both sides of anchor ear offer screw, the screw respectively expansion bolt vertical with is connected by thread fit, and the expand tube partial fixing of expansion bolt is in pond body bottom.On aeration supervisor, can also fixing horizontal setting device regulate to facilitate at Chi Tizhong.
The two ends connection of the DN50 film micropore aeration tube that this annular aeration supervisor's interior ring is parallel with many, its micropore generally forms by conventional mechanical tapping, and described micropore size is preferably 1.0mm, the preferred 0.35-1.0mm of wall thickness.So that produce bubble diameter, maintain between 1.0-1.5mm, maintain higher oxygen utilization rate, guaranteed the homogeneity of gas distribution in oxygenation requirement in whole service range and pond.Its film adopts TPU(Polyurethane Thermoplastic Elastomer) film, have that the incomparable intensity of other plastic, rubber material is high, the characteristic such as good toughness, wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant, weather, he has the function of many excellences such as high water-repellancy water vapour permeability, windproof, cold-proof, antibacterial, mildew-resistant, warming, uvioresistant and energy release simultaneously.Its mechanical property can reach: tensile strength (longitudinally): 1850 pounds per square foots, can elongatedness: 600%, tear strength: 100 pounds per square foots.
Film micropore aeration tube is equidistantly fixed with supporting tube outward, in Figure of description, do not draw the structure of supporting tube, but for reaching the object of support film micropore aeration pipe, those skilled in the art can be according to the position that supporting tube need to be set of oneself, for example domestic patent documentation CN2527555Y just provides a kind of set-up mode of supporting tube, different from this patent, supporting tube of the present utility model is not connected and washes by water with water route.Micropore is not contained at the position that film micropore aeration tube is connected with supporting tube, guarantees after long-play, diaphragm deformation can not occur.As shown in Figure 3, described film micropore aeration tube outer hoop has cingulum, and cingulum bottom is fixedly connected with level(l)ing device, and level(l)ing device is fixed on body bottom, pond by setscrew.At the bottom of film micropore aeration tube is fixed on pond by stainless level(l)ing device, be that air is responsible for air feed by aeration, supporting tube inside is water-filling not, such design makes aeration film air feed even, improve oxygen utilization rate, reduced drag losses simultaneously, at the bottom of level(l)ing device adopts stainless steel expansion bolt to be fixed on pond, guarantee no matter arm is subject to buoyancy or influence of gravity, all there will not be system failure phenomenon, up-down adjustment device can also be set, to make up the error that injustice is brought at the bottom of civil engineering pond, guarantee gas distribution pipe level; Can also before and after regulate to guarantee to expand with heat and contract with cold, brought to the damage of pipeline and compensation piping displacement.
In addition, on film micropore aeration tube, be also provided with water and get rid of device.Water is got rid of the flushometer of the similar this area of device routine, and the pressure air that flushometer brings with gas blower coordinates, to remove the mud in aeration tube.
During work, the film that struts film micropore aeration tube under the effect of gas blower rushes oxygen in biological reaction tank, when aeration stops, film is closed, thereby reach the requirement of anti-clogging plug, reverse-filling, counterflow-preventing, guaranteed that sewage can not enter in aerator, prevent sludge blockage, after stopping the supple of gas or steam for a long time, normal aeration still.
