①Rotary paddle agitator
Constituted by 2 to 3 propelling propeller blades, the working speed is high, the circumferential speed of the outer edge of the blades is generally 5-15m/s. Rotary paddle agitators are mainly used to cause axial liquid flow and generate a large amount of circulation, and are suitable for mixing low-viscosity (＜2Pa-s)Liquids,Emulsions,和solids，suspensions with particle content less than 10%. The particle content is less than 10% of the suspension. The rotating shaft of the agitator can also be inserted horizontally or obliquely into the tank, in which case the circulation circuit of the liquid flow is asymmetric, which can increase the turbulence and prevent the liquid surface from sinking.
②Turbine agitator
Constituted by the installation of two to four flat or curved blades on a horizontal disk. The ratio of the outer diameter, width and height of the paddles, generally 20:5:4, the circumferential speed is generally 3 to 8 m / s. Turbine in the rotation of the radial flow caused by a high degree of turbulence, suitable for gas and insoluble liquids dispersion and liquid-liquid phase reaction process. The viscosity of the stirred liquid is generally not more than 25Pa-s.
③Paddle stirrer
There are two types of paddle stirrer: flat paddle stirrer and inclined paddle stirrer. Flat paddle mixer consists of two flat paddles. Paddle diameter and height ratio of 4 ~ 10, circumferential speed of 1.5 ~ 3m / s, the resulting radial liquid velocity is small. Inclined paddle agitator of the two leaves opposite folded 45 ° or 60 °, thus generating axial liquid flow. Paddle stirrer structure is simple, commonly used in the mixing of low-viscosity liquids as well as the dissolution and suspension of solid particles.
④Anchor agitator
The shape of the outer edge of the paddle blade should be the same with the inner wall of the mixing tank, and there is only a small gap between them, so that the viscous reaction products attached to the tank wall or the solids piled up on the bottom of the tank can be removed, and a better heat transfer effect can be maintained. The circumferential speed of the outer edge of the paddle is 0.5~1.5m/s, which can be used to stir the Newtonian fluid with viscosity up to 200Pa-s and the proposed plastic fluid (see viscous fluid flow.). Only when mixing high viscosity liquid, there is a large stagnation zone in the liquid layer.
5 spiral belt agitator
The outer diameter of the spiral belt is equal to the pitch of the screw, specially used for mixing high-viscosity liquids (200-500Pa-s) and plasticized fluids, usually operated in laminar flow.
6 Magnetic Stirrer
The Corning digital heater has a closed-circuit knob to monitor and adjust the stirring speed. The microprocessor automatically adjusts the motor power to suit aqueous, viscous and semi-solid solutions.
7 Magnetic Heating Stirrers
Corning Digital Heating Stirrers come with an optional external thermostat (Cat. No. 6795PR), which allows them to monitor and control the temperature in the vessel.
⑧Folded Blade Stirrer
Selecting the appropriate stirring according to the physical properties of different media, capacity, and purpose of stirring,]? To promote the speed of chemical reaction, improve production efficiency can play a great role. Folded-blade turbine stirrer is generally adapted to the reaction of gas-liquid phase mixing, and the stirrer rotation should generally be selected above 300r/min.
9 frequency double layer stirrer
Frequency stirrer base, support rod, motor using patented technology fixed as one. Patented collet, no loosening, no swaying, will not fall off, safe and reliable. The chrome-plated support rod is thick at the bottom and thin at the top, with strong steel and reasonable structure. It has the advantages of easy to move and light weight. Suitable for all kinds of small containers.
