Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration control device for a sewage pool. Background Art

[0002] In the process of sewage treatment, aeration is generally used to enhance the decomposition of organic matter in sewage. Nowadays, there are generally two ways of aeration. One is to inject oxygen into the pool through impellers and high-pressure pumps to mix the sewage, and the second is to use biological aeration to aerate the sewage in the treatment pool. Generally, aeration is a common way to treat sewage.

[0003] Generally, when sewage is treated by aeration, the flow of incoming air cannot be controlled. When the gas flow needs to be increased at a certain point, the power of the air pump is usually increased. In this way, when the air is discharged from several aeration holes, the gas flow will still decrease, and the desired effect is often not achieved, resulting in reduced aeration efficiency. Therefore, there is an urgent need for sewage pool aeration control devices to solve this type of problem. Utility Model Content

[0010] As a further solution of the present invention, racks are fixed to one end of the two second sliders close to the gear, and the racks are respectively engaged with the two ends of the gear. The gear will engage with the racks and drive the second sliders closer to each other.

It is simple to operate and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
