Abstract
The invention discloses a novel underwater oxygenation aeration device. The novel underwater oxygenation aeration device comprises an aeration device shell and a micro-pore membrane, wherein the micro-pore membrane and the upper end of the aeration device shell are in sealed connection; an air inlet pipe is arranged at the lower part of the aeration device shell; the air inlet pipe upwards extends into the aeration device shell; the upper end part of the air inlet pipe is provided with an air inlet hole and two supporting rods; and a hollow cone-frustum-shaped shielding plate is arranged on the two supporting rods. With the adoption of the manner, the novel underwater oxygenation aeration device is simple in structure, and sludge can be delayed to block the air inlet pipe, so that the service life of the aeration device is prolonged.
Description
Technical field
The present invention relates to technical field of sewage treatment equipment, particularly relate to oxygenic aeration device in a kind of novel water.
Background technology
In industrial sewages such as weaving, printing and dyeing, papermaking, chemical industry and city domestic sewage biochemical processing process process, aerator is widely used, and provides biochemical water treatment required dissolved oxygen.At present, more common a kind of aerator is the microporous membrane aerator.
Existing microporous membrane aerator in the course of the work, along with micropore repeat open and close, it is big that the aperture of micropore becomes, mud enters in the aerator easily, back of long duration is stopped up inlet pipe, the work-ing life of having reduced aerator easily.
Summary of the invention
The technical problem that the present invention mainly solves provides oxygenic aeration device in a kind of novel water, and is simple in structure, can delay the sludge blockage inlet pipe, thereby prolongs the work-ing life of aerator.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: oxygenic aeration device in a kind of novel water is provided, comprise: aerator housing and microporous membrane, the upper end of described microporous membrane and described aerator housing is tightly connected, described aerator lower part of frame is provided with inlet pipe, described inlet pipe extends upwardly into the inside of described aerator housing, the upper end of described inlet pipe is provided with an air inlet port and two poles, and described two poles are provided with an open circles frustum shape shutter.
In a preferred embodiment of the present invention, the bottom surface of described open circles frustum shape shutter is positioned at the below of described air inlet port, leaves the slit between described open circles frustum shape shutter and the described inlet pipe.
In a preferred embodiment of the present invention, end face and the distance between the described microporous membrane of described open circles frustum shape shutter are 0.5 ~ 1cm.
In a preferred embodiment of the present invention, the aperture of the micropore on the described microporous membrane is 260 ~ 350 μ m.
The invention has the beneficial effects as follows: oxygenic aeration device in the novel water that the present invention discloses, simple in structure, can delay the sludge blockage inlet pipe, thereby prolong the work-ing life of aerator.
Description of drawings
Fig. 1 is the structural representation of oxygenic aeration device one preferred embodiment in the novel water of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, aerator housing, 2, microporous membrane, 3, inlet pipe, 4, air inlet port, 5, pole, 6, open circles frustum shape shutter.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
Oxygenic aeration device in a kind of novel water, comprise: aerator housing 1 and microporous membrane 2, described microporous membrane 2 is tightly connected with the upper end of described aerator housing 1, the bottom of described aerator housing 1 is provided with inlet pipe 3, described inlet pipe 3 extends upwardly into the inside of described aerator housing 1, the upper end of described inlet pipe 3 is provided with an air inlet port 4 and two poles 5, and described two poles 5 are provided with an open circles frustum shape shutter 6.
The bottom surface of described open circles frustum shape shutter 6 is positioned at the below of described air inlet port 4, leaves the slit between described open circles frustum shape shutter 6 and the described inlet pipe 3.
Along with the accumulation of duration of service, have mud and enter aerator housing 1 inside, mud is deposited in aerator housing 1 bottom, can not enter in the inlet pipe 3 at the beginning, thereby it is blocked to have delayed inlet pipe 3.
End face and the distance between the described microporous membrane 2 of described open circles frustum shape shutter 6 are 0.5 ~ 1cm.
The aperture of the micropore on the described microporous membrane 2 is 260 ~ 350 μ m.
Oxygenic aeration device in the novel water that the present invention discloses, simple in structure, can delay the sludge blockage inlet pipe, thereby prolong the work-ing life of aerator.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
