Sewage submersible mixer is also called submersible because the submersible equipment itself has a certain mixing capacity and spraying effect. If there is any function of the equipment, in fact, its function is to mix the suspended particles in the sewage treatment plant with some sludge to play a spraying role. It is a medium to promote the next step of operation and a good helper. The submersible mixer is a complex work, and the correct selection will not directly affect the normal use of the equipment.
Drive the impeller to rotate, stir the liquid, generate vortex jet and axial push flow, and the formed jet is mixed by shear force along the jet surface, so that the liquid outside the flow field is stirred. By friction; Flow, using axial thrust to move the controlled fluid forward. Under the combined mixing, stirring and pushing of swirling jet and axial push flow, volume flow is formed, and the required water flow rate and process flow field are obtained by using the mass flow method.
The selection of submersible mixer is a complicated work. Whether the type selection is correct will directly affect the normal use of the equipment. of course. According to different process requirements of sewage treatment plant.
Therefore, before type selection, it is necessary to determine the use site of submersible mixer, such as sewage pool, sludge pool and biochemical pool; Secondly, the parameters of the medium, such as: suspended solids content, viscosity, temperature, PH value; And the shape and depth of the pool. The matching power required by the mixer shall be determined according to the volume, the density of the mixing liquid and the mixing depth. One or more mixers shall be selected according to the specific situation.
