Details:

The anchor type and frame type agitator belong to the same class, which is called the anchor frame agitator. The impeller diameter of the mixer is larger for the tank diameter. When using low viscosity liquid, the blade diameter of the anchor impeller is 0.7 to 0.9, and the high viscosity liquid is 0.8-0.95. The rotational speed is usually 10 ~ 50r/min. Stir in order to increase the scope and take away the impaction of the residue or liquid layer, anchor box stirrer outer profile close to the drum wall, at the bottom of the shape in order to adapt to the bottom of the tank has the outline of ellipse, cone, etc. In order to increase the scope of high viscosity material mixing and impeller rigidity, also often in anchor and frame to add some leaves and beams, which makes the anchor frame structure shape appeared diverse.

Application:

The anchor frame agitator is usually operated at low speed and does not produce large shear force when mixing low viscosity liquid, so it does not apply to liquid-liquid and gas-liquid dispersion. Another aspect, the impeller of the tank mobile traffic is large, dominant level rotary flow, do not have good mixing uniformity, but near the tank wall velocity than other impeller, can achieve greater heat transfer film coefficient, reason often used in heat transfer, crystal analysis operation. In addition, because of the larger diameter of the blade and close to the bottom of the tank, it is also used to stir the high concentration of slurry and sedimentary slurry. It is also used for high viscosity fluid agitation.
