Abstract
The utility model relates to an aeration stirrer. Aeration devices in existing sewage treatment have large energy consumption and low air dissloving efficiency. The utility model is characterized in that a pushing flow stirring paddle which can generate downward thrust force is arranged in a flow guiding cylinder; the upper part and the lower part of the flow guiding cylinder are provided with an opening; an air distribution pipe communicated with a blower is arranged under the pushing flow stirring paddle. When the utility model works, a low pressure area is generated surrounding the air distribution pipe under the stirring paddle which makes liquid generate violent radial and axial movements, and air in the air distribution pipes can easily enter stirring liquid. The utility model can save electricity by 35-80%, and the oxygen efficiency of the utility model can reach 35-45%.
Description
The utility model belongs to the aeration agitation device that is used for sewage disposal.
Aerating apparatus in the existing sewage disposal is common surface aeration equipment and blast aeration device, and the former carries out high-speed stirring to sewage, makes gas soluble in water, the latter is that Xiang Shuizhong feeds gas under pressure, make gas water-soluble, these two kinds of devices all exist power consumption big, the inefficient deficiency of molten gas.
The utility model aims to provide a kind of existing agitating function, and aeration performance is arranged again, and it is little to consume energy, the aeration agitation device that aeration efficient is high.
The technical scheme that realizes above-mentioned purpose is (referring to implementing illustration), this device is provided with vertical to the rotating shaft (2) that is contained on the shaft supporting frame in the guide shell (3) of upper and lower opening, it is characterized in that, the plug-flow stirring rake (4) that can produce downward direction thrust is housed in the rotating shaft, plug-flow stirring rake below is provided with the gas distribution pipe (9) of band qi-emitting hole, gas distribution pipe inlet and gas blower UNICOM.
Its principle of work is, this device is placed sewage, the plug-flow stirring rake of rotation produces whipping force and downward thrust, make liquid produce fierce axial and radial motion, thereby form an area of low pressure around the gas distribution pipe below stirring rake, the gas that gas blower blasts by qi-emitting hole is easy to enter this low pressure liquid zone and is dissolved in wherein.If change the supply of gas, can adjust the gas dissolving amount, do not influence it simultaneously and mix function.
The utility model can be made aerating apparatus usefulness when aerobic treatment, also can turn-off the gas that feeds and use as simple agitator when anaerobic treatment.
This apparatus structure is simple, and is easy for installation, both had aeration performance, also has simple agitating function, aspect aeration performance, saves power consumption 35-80% than existing blast aeration, surface aeration equipment simultaneously, and oxygen efficiency can reach 35-45%.

The embodiment explanation
This example axle resting support 5 is fixed on the vertical on the flow deflector 8 at guide shell 3 inner chambers middle part of upper and lower opening, and the rotating shaft 2 that links to each other with step-down gear 1 is vertical to the fixed hub 6 that passes on the shaft supporting frame; The plug-flow stirring rake 4 that can produce downward thrust is equipped with on its top, the gas distribution pipe 9 of band qi-emitting hole 12 is a ring pipe, level is to being located at thrust stirring rake below, and gas distribution pipe communicates with the inlet pipe that links to each other with gas blower, also is provided with degree of depth stirring rake 6 in the rotating shaft that is positioned at below the gas distribution pipe.Degree of depth stirring rake can further be strengthened the stirring to liquid, improves dissolved-air rate.
Claims (2)
1, Aeration stirrer, this device is provided with vertical to the rotating shaft (2) that is contained on the shaft supporting frame in the guide shell (3) of upper and lower opening, it is characterized in that, the plug-flow stirring rake (4) that can produce downward direction thrust is housed in the rotating shaft, plug-flow stirring rake below is provided with the gas distribution pipe (9) of band qi-emitting hole, gas distribution pipe inlet and gas blower UNICOM.
