Problems solved by technology
In reality, due to various conditions, such as the continuous development of the oxidation ditch, the fluid thrown by the impeller when the inverted umbrella aerator is running is not fully in contact with the air, resulting in a mediocre oxygenation capacity and the deposition of deep dirt, which affects Fluid circulation and deep sewage promotion lead to the inability to provide sufficient oxygen to the middle and lower parts of the oxidation ditch, and cannot achieve a good oxygenation effect, which directly leads to poor aeration and oxygenation performance

Embodiment approach
[0033] figure 1 It is an embodiment of a diversion optimization device for an inverted umbrella type aerator proposed by the present invention, which specifically includes: a baffle plate (1) and a bracket (2) of the diversion optimization device.
[0034] like figure 1 As shown in the figure, the motor is connected with the reduction box and the inverted umbrella seat through the coupling, and is fixed on the foundation plane through the supporting member. The inverted umbrella type aerator is installed under the inverted umbrella seat, and the inverted umbrella type aerator Diameter D=150mm.
[0035] The baffle plate (1) of the diversion optimization device is installed directly below the inverted umbrella aerator, the bracket (2) is installed and fixed at the bottom of the oxidation ditch by bolts, and the baffle plate (1) and the bracket (2) are connected by welding.
[0036] The support (2) of the backflow optimization device is covered with small holes, so that larger ...

The invention provides a flow guide optimization device for an inverted umbrella-shaped aerator, which comprises a flow guide device baffle (1) and a flow guide device bracket (2), and can significantly improve the oxygenation performance and oxygen transfer efficiency of the inverted umbrella-shaped aerator. The flow guide device is additionally arranged at the bottom of the aeration tank, in the operation process of the inverted umbrella aeration machine, a water body in the aeration tank is influenced by the flow guide device, the flowing characteristics of internal fluid are changed, deep sewage is lifted to a shallow layer more easily and quickly, circulation is accelerated, the updating of a gas-liquid contact surface is accelerated, and the oxygen mass transfer rate is enhanced; the impeller rotates to wrap more sewage to be in contact with oxygen, the gas-liquid contact area is increased, and the oxygenation performance is enhanced. Compared with a traditional device, the device has the advantages that the oxygenation performance of the inverted umbrella-shaped aerator is obviously enhanced, and the device is reasonable in design and obvious in optimization effect.
Description
technical field [0001] The invention belongs to the research field of environmental protection equipment and fluid machinery, and particularly relates to a diversion optimization device for an inverted umbrella type aerator. Background technique [0002] my country is a country with a serious shortage of water resources. The total amount of freshwater resources ranks fourth in the world, but the per capita water resources are only 1 / 4 of the world average. With the rapid development of industry and social economy, the problem of water pollution has become increasingly prominent. The treatment of domestic sewage and industrial sewage plays a very important role in the protection of the natural environment and the development of cities. Therefore, sewage treatment is an important link in the construction of ecological civilization. [0003] As a traditional machine, the inverted umbrella aerator integrates stirring, mixing and oxygenation, and plays a vital role in the field o...
