Description
Technical field
It the utility model is related to technical field of sewage, more particularly to a kind of aerating pipelines.
Background technology
During handling sewage, it can realize that sewage denitrification and dephosphorization is made by aeration tank microorganism alternating action
With.Because aeration tank needs to adjust dissolved oxygen to adapt to different type, such as anaerobism, anoxic, the growth ring of aerobic microorganism
Border, it is therefore desirable to which the dissolved oxygen of various concentrations is provided from air blower by pipeline into pond, it is ensured that the normal biochemical work in aeration tank
With.But when blower fail or abnormal power-down, negative pressure backflow will occur for aerating pipelines, both influence pipeline aeration head
In the life-span, the normal work of aeration tank is influenceed again.
Utility model content
In order to when aerating pipelines produce negative pressure for some reason, protect aeration head and pipeline, the utility model proposes one kind to be aerated
Pipeline.
The technical solution of the utility model is as follows：A kind of aerating pipelines, including air inlet pipe and an at least appendix, it is described
Air inlet pipe is connected by Air-regulating valves with the appendix respectively, is arranged on the appendix above aeration tank towards aeration tank
At least one aeration head is simultaneously provided with, one side of the appendix backwards to aeration tank is provided with check valve, when the appendix
During interior generation negative pressure, the check valve conducting, to connect the appendix inside and atmospheric environment.
The beneficial effects of the utility model are：At least appendix for the aerating pipelines being arranged on above aeration tank can be with
To needing the aeration tank of different dissolved oxygen environment to provide dissolved oxygen, the aeration head set below appendix is stretched into corresponding aeration tank
In treatment sewage.When providing the blower fail or abnormal power-down of power for conveying dissolved oxygen, microorganism will be rapid
The dissolved oxygen in aeration tank is run out of, the appendix connected by aeration head with aeration tank will likely produce negative pressure, sewage
In fine particle, the object such as impurity will because negative-pressure adsorption on the outside of aeration head by entering aeration head, and then blocking aeration head,
Influence the service life of aeration head and pipeline.It is arranged at when the check valve at the appendix back side produces negative pressure in appendix and turns on,
To connect appendix inside and atmospheric environment, closed in pipeline normal work, so as to prevent sewage from reversely flowing into aerating pipelines,
Protect aeration head and pipeline.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the aeration tube road includes three appendixs.
It is using the above-mentioned further beneficial effect of scheme：Three appendixs can be micro- to anaerobism, anoxic, aerobic respectively
Aeration tank where biological carries out gas transmission.
Further, the air inlet of the air inlet pipe is provided with Air-regulating valves.
It is using the above-mentioned further beneficial effect of scheme：Set Air-regulating valves can be according to reality in the air inlet of air inlet pipe
Situation adjusts the intake of air blower, makes aeration effect more preferable.
Further, the aeration head is micro porous aeration head.
It is using the above-mentioned further beneficial effect of scheme：Micro porous aeration head can make dissolved oxygen more fully dissolve in aeration
In the sewage in pond, make aeration effect more preferable.
Further, the trend of the appendix is S-shaped.
It is using the above-mentioned further beneficial effect of scheme：S-shaped trend appendix by with the waste water in aeration tank
More fully, make aeration effect more preferable.
Further, the air inlet pipe and the appendix are pvc pipe.
It is using the above-mentioned further beneficial effect of scheme：The easily disassembled installation of pvc pipe, when pipeline breaks down, side
Just repaired and changed.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are
Some embodiments of the utility model, for those of ordinary skill in the art, do not paying the premise of creative labor
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of aerating pipelines of the utility model embodiment.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in figure 1, the aerating pipelines that the utility model embodiment provides include air inlet pipe 1 and an at least appendix 2,
Air inlet pipe 1 is connected by Air-regulating valves 3 and appendix 2 respectively, is arranged on the appendix 2 of the top of aeration tank 6 towards the one of aeration tank 6
Face is provided with least one aeration head 4, and one side of the appendix 2 backwards to aeration tank 6 is provided with check valve 5, when generation in appendix 2
During negative pressure, check valve 5 turns on, to connect the inside of appendix 2 and atmospheric environment.
At least appendix for the aerating pipelines being arranged on above aeration tank can be to the exposure for needing different dissolved oxygen environment
Gas pond provides dissolved oxygen, and the aeration head set below appendix is stretched into the treatment sewage in corresponding aeration tank.When for conveying
When dissolved oxygen provides the blower fail or abnormal power-down of power, dissolving that microorganism will be run out of rapidly in aeration tank
Oxygen, the appendix connected by aeration head with aeration tank will likely produce negative pressure, the thing such as fine particle, impurity in sewage
Body will influence making for aeration head and pipeline because negative-pressure adsorption is by entering aeration head, and then blocking aeration head on the outside of aeration head
Use the life-span.It is arranged at when the check valve at the appendix back side produces negative pressure in appendix and turns on, it is inside appendix and big to connect
Compression ring border, closed in pipeline normal work, so as to prevent sewage from reversely flowing into aerating pipelines, protect aeration head and pipeline.
Preferably, the aeration tube road includes three appendixs 2.
Three appendixs can respectively to anaerobism, anoxic, aerobic Institute of Micro-biology aeration tank carry out gas transmission.
Preferably, the air inlet of air inlet pipe 1 is provided with Air-regulating valves.
Set Air-regulating valves to adjust the intake of air blower according to actual conditions in the air inlet of air inlet pipe, imitate aeration
Fruit is more preferable.
Preferably, aeration head 4 is micro porous aeration head.
Micro porous aeration head can be such that dissolved oxygen more fully dissolves in the sewage of aeration tank, make aeration effect more preferable.
Preferably, the trend of appendix 2 is S-shaped.Appendix 2 is preferably provided with multiple uniform towards the one side of aeration tank 6
The aeration head 4 of distribution.
The appendix of S-shaped trend will be more abundant with the waste water in aeration tank, makes aeration effect more preferable.
