Problems solved by technology

[0007] The cutting-type impeller-type surface aeration aerator cuts the water surface through the impeller to realize the mixing of water body and oxygen, and forms high dissolved oxygen near the impeller. The actual situation is that the cutting-type impeller aerates the dissolved oxygen efficiency is not high, and it is not easy to transmit oxygen to a long distance
[0008] Underwater aeration generally installs a networked aeration pipe system on the bottom of the water, and aerates through a fan. This aeration method has good oxygenation efficiency and uniform oxygenation. However, the installation of the aeration pipe needs to drain the water body, and it needs to be installed and fixed. Pile, and the blockage of the aeration pipe is also a disadvantage of underwater aeration

Embodiment Construction

[0040] What is to be processed in this embodiment is an area of ​​6300m 2 , the plane shape is nearly circular, relatively regular, and the pond with an average water depth of 2m uses a single surface harmonic surface aerator for oxygenation treatment.

[0041] Referring to the accompanying drawings, the curved surface harmonic surface exposure machine used in this embodiment includes a motor 1 fixed on the top of the buoy 2, and a blade 4 linked with the motor 1 through a connecting rod 3. The blade 4 is arranged coaxially with the connecting rod 3 The ring, which regularly fluctuates up and down along the circumference, is in the shape of a sine wave.

[0042] The bottom of the connecting rod 3 is provided with a fixed sleeve 6, and the blade 4 is installed on the periphery of the fixed sleeve 6 through a bracket 5. The bracket 5 is four spokes connected between the fixed sleeve 6 and the blade 4.

[0043] The connecting rod 3 extends to below the buoy 2, and the length of ...

Abstract

The invention discloses a curved surface harmonic wave surface aerator. The curved surface harmonic wave surface aerator comprises a motor and a blade linked with the motor by a coupling rod. The blade is a ring coaxial with the coupling rod. The ring has a regular undulating shape along a circumferential direction. The curved surface harmonic wave surface aerator utilizes the blade with the particular shape, and the blade can form harmonic wave uniformly propagated to the whole water surface so that uniform oxygen charge of the water surface is realized. The curved surface harmonic wave surface aerator is convenient for installation and is not blocked easily.

Description

technical field [0001] The invention relates to the technical field of surface exposure machines, in particular to a curved surface harmonic surface exposure machine. Background technique [0002] In recent years, the construction of urban sewage treatment plants in my country is developing at an unprecedented speed, and hundreds of urban sewage treatment plants are currently under construction. Among the leading processes of urban sewage treatment plants, the oxidation ditch process has been paid more and more attention due to its simple process, high cost efficiency, convenient management, simple equipment, etc., as well as its strong ability in denitrification. Wide range of applications, especially suitable for small and medium-sized urban sewage treatment plants. [0003] The key equipment of the oxidation ditch process is the surface aerator (referred to as the surface aerator), which is used for oxygenation of the aeration tank of the sewage treatment plant, and the ...
