Description

A kind of sewage disposal aeration head

Technical field

In sewage disposal process by activated sludge process, because technological requirement needs, in order that activated sludge is in consersion unit It is middle into suspended state, make mixed liquor well mixed, it is necessary to the need for compressed air is passed through in processing pond to meet technique.Useless Generally realize that aeration aerating is operated in pond using aeration tube and aeration head, current aeration head is generally micropore membrane type aeration Head, its form is the microporous barrier that lining sets elasticity in a hard, the hole under the air pressure in aeration on elastic microlevel membrane Open and be aerated in pond, elastic micropore pinch confinement realizes the function of sealing during stuffiness, this aeration head has following defect：One Need to expend larger energy when being and opening the hole on microporous barrier, these energy are included for overcoming elastic microlevel membrane and liner Between power and the power for opening microporous barrier, these energy to formed bubble be useless；Two be microporous barrier repeatedly Open shrink be easily caused its elasticity change and other manner damage, particularly in the case of air pressure shakiness, and expose The damage of gas head is generally embodied in the damage of microporous barrier.

The content of the invention

The purpose of this utility model is the above mentioned problem for overcoming the aeration head for using at present to exist, there is provided at a kind of sewage Reason aeration head.

To realize the purpose of this utility model, following technical schemes are employed：A kind of sewage disposal aeration head, it is described Aeration head be tubulose, one end of tubulose has the connection screw thread between gas distributing pipeline, and described aeration head includes internal layer Stereoplasm tube and the elastic microlevel membrane being set on stereoplasm tube, tight fit between elastic microlevel membrane and stereoplasm tube, on hard tube wall Multiple ventholes are offered, sunk structure is provided with described hard pipe outer wall, described sunk structure is pit or edge Groove on stereoplasm tube length direction, further, described sunk structure is the multiple arcs for being opened in hard tube outer surface Pit, multiple arcs pit is arranged along stereoplasm tube in stereoplasm tube in row, is handed over along the circumferentially upper two adjacent row arc pits of stereoplasm tube Mistake is set, and further, described sunk structure is the multiple arcs elongated slot opened up along stereoplasm tube length direction, described arc Elongated slot is arranged circumferentially along stereoplasm tube, and the shared ratio in hard pipe outer wall circumference of arc elongated slot is 20-40%.

Positive Advantageous Effects of the present utility model are：One is the presence due to there is sunk structure, elastic microlevel membrane Real contact area between tube wall reduces, and the more traditional aeration head of elastic microlevel membrane increased very big elastic space, exposes Required " elastic resistance " for overcoming diminishes during gas, can effectively reduce the energy ezpenditure in aeration process；Two is aeration knot Microcellular elastomeric film is provided with larger shrink space after beam, can be good at shrinking, and closing is tight, and strong in its holding bullet Property；Extend its service life, reduce spoilage；Three is that these sunk structures form air chamber one by one in itself in aeration, is made Gas in more large area can be entered into pond by micropore, improve the aeration rate and aeration effect of unit area.This reality It is simple with new structure, it is easy to accomplish, effect is good, low cost.

Specific embodiment

In order to more fully explain implementation of the present utility model, there is provided embodiment of the present utility model.These implement real Example is only, to elaboration of the present utility model, scope of the present utility model not to be limited.

With reference to accompanying drawing to the further details of explanation of the utility model, in accompanying drawing each mark for：1：Stereoplasm tube；2：Elasticity is micro- Pore membrane；3：Venthole；11：Sunk structure.As shown in drawings, a kind of sewage disposal aeration head, described aeration head is tubulose, One end of tubulose has the attachment structure between gas distributing pipeline, and described aeration head includes the stereoplasm tube 1 of internal layer and is set in Elastic microlevel membrane 2 on stereoplasm tube, tight fit between elastic microlevel membrane 2 and stereoplasm tube 1, on hard tube wall offering multiple goes out Stomata, 3 show a venthole, and sunk structure is provided with described hard pipe outer wall, and 11 show sunk structure, described Sunk structure for pit or along the sunk structure described in the groove on stereoplasm tube length direction to be opened in stereoplasm tube appearance The multiple arcs pit in face, multiple arcs pit, along stereoplasm tube arrangement in a row, adjacent two along stereoplasm tube is circumferential in stereoplasm tube Row arc pit is staggered, and as indicated at 3, described sunk structure is along hard length of tube side to the sunk structure of arc pit To the multiple arcs elongated slot for opening up, described arc elongated slot is arranged circumferentially along stereoplasm tube, and arc elongated slot is in hard pipe outer wall Shared ratio is 20-40% in circumference, and effect on driving birds is not good if proportion is too small, ratio is excessive, in the case where not being aerated The probability that leak occurs increases.

After implementation method of the present utility model is described in detail, one of ordinary skilled in the art is clearly understood that, Do not depart from that above-mentioned claim is lower with spirit can be carried out various change and change, it is all according to technical spirit of the present utility model Any simple modification, equivalent variations and the modification made to above example, belong to the scope of technical solutions of the utility model, And the utility model is also not only restricted to the implementation method of example in specification.
