Flocculation mixer is mainly used in coagulation process of water supply and drainage. Flocculation mixer is to promote the role of colloidal particles collide, adsorption and gradually form a certain size of vanadium flowers, the majority of colloidal particles in the form of vanadium precipitation down.
Mixing intensity and mixing time is the key to determine the flocculation effect. The mixing intensity (i.e. G) in the flocculation pool should be decreased, and the line speed of the center of the propeller blades of each file is gradually slowed down, and the mixing time should be sufficient to complete the flocculation process.
The flocculation mixer can meet flocculation rules, make each section in the flocculation process with different stirring intensity, changes can be suitable for water and the water temperature, water head has the advantages of little damage, simple basin structure, convenient combination of external energy.
The flocculation mixer can adjust the mixing intensity with the change of the water quantity, the turbidity of the raw water and the dosage of the water, and the flocculation effect can be achieved, and the dosage of the medicament can be saved.
Flocculation mixer according to the installation of the mixing shaft into a vertical mixer and two kinds of vertical mixer. Horizontal flocculation mixer paddles near the bottom of rotation, the general flocculation of sludge accumulation does not exist.
Most of the flocculation mixer adopts frame type mixer, and the frame type mixer is divided into three forms, which are the straight blade, the oblique blade and the net blade.
