Abstract
The utility model discloses a novel underwater oxygenation aerator which comprises an aerator housing and a microporous membrane; the microporous membrane is hermetically connected with the upper end of the aerator housing; an air inlet pipe is arranged at the lower part of the aerator housing, and extends upwards into the inner part of the aerator housing; an air inlet hole and two fulcrum bars are arranged at the upper end part of the air inlet pipe; a hollow cone frustum-shaped baffle plate is arranged on the two fulcrum bars. Therefore, the novel underwater oxygenation aerator has a simple structure, and can slow down the speed of sludge entering into the air inlet pipe, and the service life of the aerator is further prolonged.
Description
Technical field
The utility model relates to technical field of sewage treatment equipment, particularly relates to oxygenic aeration device in a kind of new type water.
Background technology
In the 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 microporous diaphragm aeration apparatus.
In the course of the work, along with the keying that repeats of micropore, it is large that the aperture of micropore becomes existing microporous diaphragm aeration apparatus, and mud easily enters in aerator, rear easy obstruction inlet pipe of long duration, the work-ing life of having reduced aerator.
The utility model content
The technical problem that the utility model mainly solves is to provide oxygenic aeration device in a kind of new type water, simple in structure, can delay the sludge blockage inlet pipe, thereby extends the work-ing life of aerator.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: oxygenic aeration device in a kind of new type water is provided, comprise: aerator housing and microporous membrane, the upper end of described microporous membrane and described aerator housing is tightly connected, the bottom of described aerator housing is provided with inlet pipe, described inlet pipe extends upwardly into the inside of described aerator housing, be provided with an air inlet port and two poles on the upper end of described inlet pipe, described two poles are provided with an open circles frustum shape shutter.
In preferred embodiment of the utility model, the bottom surface of described open circles frustum shape shutter is positioned at the below of described air inlet port, between described open circles frustum shape shutter and described inlet pipe, leaves gap.
In preferred embodiment of the utility model, the distance between the end face of described open circles frustum shape shutter and described microporous membrane is 0.5 ~ 1cm.
In preferred embodiment of the utility model, the aperture of the micropore on described microporous membrane is 260 ~ 350 μ m.
The beneficial effects of the utility model are: oxygenic aeration device in the new type water that the utility model discloses, and simple in structure, can delay the sludge blockage inlet pipe, thereby extend the work-ing life of aerator.
The accompanying drawing explanation
Fig. 1 is the structural representation of oxygenic aeration device one preferred embodiment in the utility model new type water;
In accompanying drawing, the mark of each parts is as follows: 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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model embodiment comprises:
Oxygenic aeration device in a kind of new type 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, be provided with an air inlet port 4 and two poles 5 on the upper end of described inlet pipe 3, 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, between described open circles frustum shape shutter 6 and described inlet pipe 3, leaves gap.
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 inlet pipe 3 at the beginning, thereby it is blocked to have delayed inlet pipe 3.
Distance between the end face of described open circles frustum shape shutter 6 and described microporous membrane 2 is 0.5 ~ 1cm.
The aperture of the micropore on described microporous membrane 2 is 260 ~ 350 μ m.
Oxygenic aeration device in the new type water that the utility model discloses, simple in structure, can delay the sludge blockage inlet pipe, thereby extend the work-ing life of aerator.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
