The main structure principle of shallow air flotation machine
The shallow air flotation machine adopts the principle of dissolved air flotation, which involves introducing a portion of dissolved air water into the water to be treated, and using the tiny bubbles released from the dissolved air water to float suspended solids or oil to the surface, thereby achieving solid-liquid separation. The main unit of a shallow air flotation machine refers to the separation part of the shallow air flotation machine, which includes the tank body, floating slag, collection device, stationary ring, overflow regulation device, walking frame, rotating inlet pipe, rotating water distribution structure, etc. The rotating part of the host includes the inlet, outlet, and sludge removal mechanism, which rotates along the pool at the same speed as the inlet water speed as the spiral scum hopper. The raw water enters from the rotating inlet pipe at the center of the pool and is distributed through the rotating part of the water pipe. The movement speed of the water distribution pipe is the same as the inlet flow rate, resulting in "zero velocity". The application of this principle is the key to shallow air flotation machines.
In this way, the inflow will not disturb the pool water, allowing particles to suspend and settle in a relatively static environment, thereby shortening the residence time. The spiral slag hopper in the scum collection device has two movements: self rotation and revolution. Self rotation sweeps away the scum on the liquid surface, while revolution allows the slag hopper to cover the entire liquid surface.
