Description

Self-cleaning aeration head

Technical field

It the utility model is related to aerator, more particularly to the aeration head of aerator.

Background technology

Aeration is a kind of means for making air be contacted strongly with water, its object is to which the oxygen in air is dissolved in the water, Or banish unwanted gas and volatile materials in water 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 disposal, because 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, for by oxygen Gas is broken into tiny bubble, so as to improve the oxygen concentration in sewage.But a large amount of bacterium flcos in sewage be present and hanged with particle Float, on the one hand, in aeration process, the Minute pores on aeration head be easy to due to bacterium attachment with particulate matter deposition and Result in blockage, aeration head is caused damage；On the other hand, when part Minute pores are blocked, inside aerator Pressure distribution is uneven, it is easy to causes the aperture of other Minute pores on aeration head to become big, increases caused bubble diameter Greatly, the aeration efficiency of aerator is reduced.

Chinese utility model patent application number CN201620841542.6 discloses a kind of automatically cleaning selfreparing aeration head, bag Include aeration head outer barrel, the aeration head inner cylinder being engaged with the aeration head outer barrel and for controlling the aeration head inner cylinder to exist The telescoping mechanism moved up and down in the aeration head outer barrel, the upper end of the aeration head outer barrel offer opening, the aeration head The upper end of inner cylinder has the bulb coordinated with the opened gap, the inwall of the aeration head outer barrel and the aeration head inner cylinder Outer wall between formed with gas channel, the support for supporting the aeration head inner cylinder is provided with the aeration head outer barrel, Multiple holes are offered on the support；The telescoping mechanism includes being used to cause the aeration head inner cylinder in the aeration head The drop-down component that is moved down in outer barrel and moved up for causing the aeration head inner cylinder in the aeration head outer barrel Reset components, the drop-down component include the magnetic part and phase that are arranged on the aeration head inner cylinder bottom to attract each other It is arranged on the electromagnetic controller of gas transmission bottom of the tube to the magnetic part, the reset components are more springs, each bullet The upper end of spring is connected with the bottom of the aeration head inner cylinder, and the lower end of the spring is connected with the support；Outside the aeration head Cylinder and the aeration head inner cylinder are respectively provided with interlayer, and the interlayer is reconditioning layer, and the reconditioning layer includes being filled with asphalt mixtures modified by epoxy resin First microcapsules of fat and the second microcapsules filled with curing agent, first microcapsules and second microcapsules are handed over Mistake is embedded in the reconditioning layer.The upper end of the aeration head inner cylinder is in round table-like, and the upper end of the aeration head outer barrel is also in Round table-like, the taper of the upper end of the aeration head inner cylinder is identical with the taper of the upper end of the aeration head outer barrel, the aeration head The diameter of the upper end of inner cylinder is identical with the opening diameter of the aeration head outer barrel, the diameter of the bulb of the aeration head inner cylinder Less than the opening diameter of the aeration head outer barrel.The aeration head is in order to realize that automatically cleaning self-repair function greatly complicates The internal structure of aeration head, one causes manufacturing cost to greatly increase, and two safeguard inconvenience, are not suitable for a wide range of promote.

Utility model content

The technical problems to be solved in the utility model is that existing aeration head is easily blocked without good clean method Or with self-cleaning function but complicated cost it is too high be not suitable for it is a wide range of promote, provided for this one kind it is simple in construction into This cheap self-cleaning aeration head.

The technical solution of the utility model is：Self-cleaning aeration head, it includes air inlet section and the ball connected with air inlet section Shape aeration head body, horizontal rotating shaft is provided with the spherical aeration head body, some blades are connected with the horizontal rotating shaft, The external peripheral surface of the spherical aeration head is communicated with some spherical cavities, and the spherical cavity surface distributed has some aerations Hole.

Horizontal rotating shaft described in such scheme has one, and the side of air inlet section, institute are deviateed in spherical aeration head body The end for stating blade is located in the extended area that air inlet section extends to spherical aeration head body.

Horizontal rotating shaft described in such scheme has two, is symmetrically distributed in the spherical aeration head body of air inlet section both sides, The end of the blade is located in the extended area that air inlet section extends to spherical aeration head body.

The improvement of such scheme is that some rolling elements are filled with the spherical cavity.

The further improvement of such scheme is the uniform flexible bristle in surface of the rolling element.

The beneficial effects of the utility model are that the air-flow band movable vane piece for being passed through air inlet section surrounds axis of rotation, and then produce and disturb Dynamic circulation, the circulation of disturbance form turbulent flow after solarization air cap is discharged at a high speed after being compressed by spherical cavity on its surface, can from The dynamic fouling removed aeration hole surface and formed, keeps the unobstructed of solarization air cap, and the utility model entirety fouling is simple, is adapted to a wide range of Promote.
