Stirrer
A device that forces liquid and gaseous media to convection and uniformly mix. The type, size and speed of the stirrer have an impact on the distribution of stirring power between the overall flow and the turbulent pulsation. Generally speaking, the power distribution of turbine mixers is good for turbulent pulsations, while the propeller mixer is good for overall flow. For the same type of agitator, under the same power consumption conditions, the power of a large-diameter, low-speed agitator is mainly consumed in the overall flow, which is conducive to macroscopic mixing.
①Propeller mixer
It is composed of 2 to 3 pusher propeller blades (Figure 2). The working speed is high, and the peripheral speed of the outer edge of the blade is generally 5 to 15m/s. The propeller mixer mainly produces axial liquid flow and produces a large circulation volume, and is suitable for stirring low-viscosity (<2Pa·s) liquids and emulsions. and suspensions with a solid particle content of less than 10%. The rotating shaft of the agitator can also be inserted into the tank horizontally or diagonally. At this time, the circulation loop of the liquid flow is asymmetrical, which can increase turbulence and prevent the liquid level from sinking.
②Turbine agitator
It consists of 2 to 4 straight or curved blades installed on a horizontal disk

Consists of. The ratio of the outer diameter, width and height of the blade is generally 20:5:4, and the peripheral speed is generally 3~8m/s. The turbine causes highly turbulent
radial flow when rotating, which is suitable for the dispersion and liquid-liquid phase reaction
processes of gases and immiscible liquids. The viscosity of the stirred liquid generally does not exceed 25 Pa·s.
③Paddle mixer
Incline paddle mixer
Incline paddle mixer
There are flat paddle type and inclined paddle type Two types. The flat paddle mixer consists of two straight paddles. The ratio of blade diameter to height is 4 to 10, the peripheral speed is 1.5 to 3 m/s, and the radial liquid flow velocity generated is small. The two blades of the inclined paddle agitator (Figure 4) are turned in opposite directions by 45° or 60°, thus producing axial liquid flow. Paddle agitators have a simple structure and are often used for mixing low-viscosity liquids and dissolving and suspending solid particles.
④Anchor mixer
The shape of the outer edge of the blade should be consistent with the inner wall of the mixing tank (Figure 5). There is only a small gap between them, which can remove the dirt attached to the tank wall. Viscous reaction products or solid objects accumulated at the bottom of the tank maintain good heat transfer effect. The peripheral speed of the outer edge of the blade is

0.5~1.5m/s, which can be used to stir viscosity up to 200Pa ·S Newtonian fluids and pseudoplastic fluids (see viscous fluid flow. Only when stirring high-viscosity liquids, there is a large stagnation area in the liquid layer.
⑤ Ribbon agitator
The outer diameter of the ribbon is equal to the pitch, and is specially used to stir high-viscosity liquids (200~500Pa·s) and pseudo-plastic fluids. It is usually operated in a laminar flow state.
⑥Magnetic 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 water quality, viscous solutions and semi-solid solutions.
⑦ Magnetic Heated Stirrers
Corning digital heated stirrers come with an optional external temperature controller (Cat. No. 6795PR), which can also monitor and control the temperature in the container.
< p>⑧Blade-type stirrerSelecting the corresponding stirrer according to the physical properties, capacity, and stirring purpose of different media can play a great role in promoting the speed of chemical reactions and improving production efficiency. Folding blade turbine stirrers are generally suitable for gas and liquid phase mixing reactions, and the stirrer rotation speed should generally be selected to be above 300r/min.
⑨ Frequency conversion double-layer mixer
The base, support rod and motor of the frequency conversion mixer are fixed into one body using patented technology. Patented chuck, no looseness, no swing, no falling off, safe and reliable. Chrome-plated struts, thick at the bottom and thin at the top, have strong rigidity and reasonable structure. It has the advantages of easy movement and light weight. Suitable for all types of small containers.
⑩Side-entry mixer
A side-entry mixer has a mixing device installed on the side wall of the equipment cylinder. The agitator on the mixer usually adopts an axial flow type to propel There are many types of stirrers, which can achieve the highest stirring effect under the same power consumption. The power consumption is only 1/3 to 2/3 of top stirring, and the cost is only 1/4 to 1/3 of top stirring. The rotation speed can be between 200~750r/min.
Widely used for desulfurization, denitrification and agitation of various large storage tanks or tanks. Especially when one or more side-entry mixers are used to work together in large storage tanks or tanks, good mixing effects can be obtained with low energy consumption.
