Abstract

The utility model relates to environmental technology fields, especially a kind of aeration head with back flush function, ontology including Ω shape, ontology one end is air inlet, and the other end is rinse mouth, is provided with valve on rinse mouth, stomata is provided on ontology, it is provided with back flush apparatus in stomata, enters air-flow or water flow from rinse mouth when the valve is open, back flush apparatus cleans stomata.The aeration head of the utility model uses the ontology of Ω shape, one end is into sewage one end into flushing water, when air-hole blockage needs back flush, open valve, push stomata to from rinse mouth water inlet by the protrusion on turnover panel, protrusion ejects the impurity blocked in stomata, it is only necessary to which periodic reverse rinses aeration head, just impurity, which can be removed, reduces failure rate, greatly improves the service life of aeration head.

Description

A kind of aeration head with back flush function

Technical field

The utility model relates to environmental technology field, especially a kind of aeration head of sewage treatment.

Background technique

Aeration is a kind of means for contacting air strongly with water, its object is to which the oxygen in air is dissolved in the water, Or banish gas unwanted in water and volatile materials in air, it is to promote mass exchange between gas and liquid A kind of means.Aerator is based on this means and is widely adopted in sewage treatment, since aerator is main For the aerobic section in biochemical wastewater treatment system, a large amount of Minute pores are offered on the aeration head of aerator, are used for oxygen Gas is broken into tiny bubble, to improve the oxygen concentration in sewage.

But there are a large amount of impurity in sewage, in aeration process, the Minute pores on aeration head are easy to be blocked up by impurity Plug, damages aeration head, influences the service life；When part Minute pores are blocked, due to the pressure inside aerator point Cloth is uneven, it is easy to cause the aperture of other Minute pores on aeration head to become larger, increase the bubble diameter generated, reduce The aeration efficiency of aerator.

Utility model content

The problem of being blocked purpose of the utility model is to solve traditional aeration head by impurity, and provide a kind of with anti- To the aeration head of pre-washing function.

The technical solution adopted in the utility model are as follows: a kind of aeration head with back flush function, the sheet including Ω shape Body, ontology one end are air inlet, and the other end is rinse mouth, and valve is provided on rinse mouth, are provided with stomata on ontology, by stomata Be provided with back flush apparatus, enter air-flow or water flow from rinse mouth when the valve is open, back flush apparatus to stomata into Row cleaning.

Further, the back flush apparatus includes the turnover panel hinged with inner body wall, and turnover panel is arranged towards stomata side There is a protrusion corresponding with stomata, when back flush, turnover panel, which rotates to stomata side protrusion and stretches out stomata, ejects the tamper of stomata.

Further, adjacent multiple stomatas share a turnover panel, correspond to each stomata on turnover panel and are provided with protrusion, more A stomata shares a turnover panel, reduces turnover panel quantity and facilitates installation and reduce cost.

Further, the raised front end is provided with the conical points for facilitating insertion stomata.

Further, the stomata is the small bell shape of outer imperial palace.

Further, the air inlet and rinse mouth be axially perpendicular to ontology where plane, facilitate air inlet and flushing Mouthful with corresponding piping connection.

The utility model has the beneficial effects that the aeration head of the utility model uses the ontology of Ω shape, one end is into sewage one end Into flushing water, when air-hole blockage needs back flush, valve is opened, intakes from rinse mouth and pushes the protrusion on turnover panel to stomata, Protrusion ejects the impurity blocked in stomata, it is only necessary to and periodic reverse rinses aeration head, and just can remove impurity reduces failure rate, Greatly improve the service life of aeration head.

Detailed description of the invention

Fig. 2 is the left view of the utility model；

Fig. 3 is the A of the utility model Fig. 1 to cross-sectional view back flush state；

Fig. 4 is the A of the utility model Fig. 1 to cross-sectional view working condition.

In figure: 1- ontology, 2- air inlet, 3- rinse mouth, 4- valve, 5- stomata, 6- back flush apparatus, 601- turnover panel, 602- protrusion.

Specific embodiment

The utility model is described further with reference to the accompanying drawing.

As shown in figs. 1 and 3, a kind of aeration head with back flush function, the ontology 1 including Ω shape, 1 one end of ontology are Air inlet 2, the other end are rinse mouth 3, are provided with valve 4 on rinse mouth 3, stomata 5 is provided on ontology 1, is provided with by stomata 5 Back flush apparatus 6, when normal use, valve 4 is closed, and is entered air from air inlet 2 and is sprayed from stomata 5, oxygen is broken into carefully Minute bubbles, to improve the oxygen concentration in sewage；When stomata 5 blocking need to clean when, valve 4 open, from rinse oral pore 5 into Enter air-flow or water flow, back flush apparatus 6 cleans stomata 5.

As shown in Figure 3 and Figure 4, back flush apparatus 6 includes the turnover panel 601 hinged with 1 inner wall of ontology, 601 direction of turnover panel Stomata side is provided with corresponding with stomata 5 raised 602, and raised 602 front ends are provided with the conical points for facilitating insertion stomata 5； When aeration head works normally such as Fig. 4 state, air turn left to flow from the right side and open turnover panel 601, and air is flowed out from stomata 5；Reversely When flushing, such as Fig. 3 state, air flows from left to right, and air push turnover panel 601 rotates to 5 side of stomata, and protrusion 602 stretches out gas Hole 5 ejects the tamper of stomata 5.

Further, three adjacent stomatas 5 share a turnover panel 601, correspond to each stomata 5 on turnover panel 601 and are respectively provided with There is protrusion 602, three stomatas 5 share a turnover panel 601, reduce 601 quantity of turnover panel and facilitate installation and reduce cost.

Further, the stomata 5 is the small bell shape of outer imperial palace, and protrusion 602 is facilitated to eject sundries from inside to outside.

Further, air inlet 2 and rinse mouth 3 are axially perpendicular to 1 place plane of ontology, facilitate air inlet 2 and rinse Mouthfuls 3 with corresponding piping connection.

Specific embodiment is the further explanation to the utility model rather than limits, and is come to those of ordinary skill in the art It says and further transformation is done to structure in the case where not departing from the utility model in essence content, and all these transformation all should belong to The protection scope of the appended claims for the utility model.
