Abstract
The utility model discloses an air inlet device of an aerator. A main air inlet pipe on an annular air inlet pipe is penetrated through a side surface of an H-shaped flange, the annular air inlet pipe is arranged in the H-shaped flange, the annular air inlet pipe is supported by a bracket which is composed of an upper bracket and a lower bracket and is tightly locked by screw bolts, the end of the lower bracket which is provided with screw threads penetrates through the side surface of the H-shaped flange, the lower bracket is fixed by screw nuts, small air outlets are uniformly distributed on the same circumference of the annular air inlet pipe, the included angle between the axis line of each small air outlet and the horizontal line is an angle alpha, and the small air outlets face the inner side. The utility model is provided with only one main air inlet pipe, the trouble caused by the original multipipe air inlet installation is altered, and the air-bubble fragmentation effect is good because of the multihole air outlet; each air outlet forms an angle with the horizontal line, which is favorable to use the initial velocity of the air flow, the air and the water mixing effect is good, and the oxygen in air-bubbles can dissolve in the water conveniently; the annular air inlet pipe can decrease the loss of the eddy kinetic energy, and thus the velocity of the air and water mixture at the nozzle point is enhanced, the service area is enlarged, and the oxygen dissolving rate is enhanced.
Description
Affiliated technical field
The utility model relates to the device of gas and liquid mixing, relates in particular to a kind of aerator diffuser.
Background technology
Present some diffuser that uses, be many inlet pipe radial radiation mounting means, install inconvenient, bubble fragmentation effect is undesirable, dissolved oxygen rate is not high when causing aerator work, the radial radiation mounting means makes eddy kinetic energy loss bigger in addition, thereby has reduced the water speed that of spout, causes service area to reduce and the bubble backwater time reduces.
Summary of the invention
The purpose of this utility model provides a kind of aerator diffuser, and the annular intake pipe that has the certain intervals production well is contained in the flange, makes the mixed effect of air water better, reduces the loss of eddy kinetic energy.
In order to achieve the above object, the technology that adopts of the utility model is: it comprise I-shaped flange, annular intake pipe, support.Main inlet pipe on the annular intake pipe is passed I-shaped flange side, annular intake pipe is contained in the I-shaped flange, hold and lock by the support that upper bracket and lower bracket are formed with bolt, the end that has a lower bracket of screw thread is passed I-shaped flange side and with nut support is fixed, uniform little production well on the same circumference of annular intake pipe, little production well axial line and sea line angle are the α angle, and little production well is towards the annular intake pipe inboard.
The beneficial effect that the utlity model has is: have only a main inlet pipe, changed original multitube air inlet the trouble that causes is installed, porous is given vent to anger, and makes the bubble fragmentation effective, production well and sea line are at angle, help utilizing the initial velocity of air-flow, make the mixed effect of air water better, the oxygen that helps in the bubble is water-soluble, annular intake pipe can reduce the loss of eddy kinetic energy, thereby improved the speed of spout place air water miscellany, increased service area, improved dissolved oxygen rate.Utility model is easy for installation.

Embodiment
As Fig. 1～Fig. 8, shown in, the utility model comprises I-shaped flange 1, annular intake pipe 2, bolt 3, support 4, nut 5; Main inlet pipe 2.1 on the annular intake pipe 2 is passed I-shaped flange 1 side, annular intake pipe 2 is contained in the I-shaped flange 1, hold and lock by the support 4 that upper bracket 4.1 and lower bracket 4.2 are formed with bolt 3, it is fixing with support 4 with nut 5 that I-shaped flange 1 side is passed in the end 4.3 that has a lower bracket of screw thread, uniform little production well on the annular intake pipe 2 same circumference, little production well axial line and sea line angle are the α angle, and little production well is towards annular intake pipe 2 inboards.
As Fig. 3, Fig. 5, shown in Figure 6, uniform little production well on the said annular intake pipe 2 same circumference, its interval angle is 7.5 °～15 °, little production well axial line and sea line angle α=30 °～60 °.
Working process is that whole device is installed in the aerator diversing bucket, and air enters from main inlet pipe by air pump, then by each little production well ejection, run into the eddy current that water screw produces, air-flow and the fully fragmentation of eddy current collision quilt, the air water thorough mixing, spouting by the guiding device spout then.
