Main types: 1. The propeller agitator is composed of 2 to 3 propeller blades. The working speed is relatively high. The peripheral speed of the outer edge of the blade is generally 5 to 15m/s. The propeller agitator mainly causes the axial liquid flow and produces a larger circulation volume. It is suitable for stirring low-viscosity (<2Pa·s) liquids, 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 surface from sinking. 2. Turbine agitator is composed of 2 to 4 flat or curved blades installed on a horizontal disc. The ratio of the outer diameter, width and height of the blade is generally 20:5:4, and the circumferential speed is generally 3-8m/s. The turbine causes highly turbulent radial flow when it rotates, which is suitable for the dispersion of gas and immiscible liquids and the liquid-liquid reaction process. The viscosity of the liquid being stirred generally does not exceed 25Pa·s.
3. Paddle agitator has two types: flat paddle type and inclined paddle type. The flat paddle agitator consists of two straight paddles. The ratio of the diameter of the blades to the height is 4-10, and the circumferential speed is 1.5-3m/s. The two blades with the smaller radial liquid flow velocity are turned oppositely by 45° or 60°, thus producing axial liquid flow. The paddle agitator has a simple structure and is often used for mixing low-viscosity liquids and dissolving and suspending solid particles. 4. The shape of the outer edge of the blade of the anchor stirrer should be the same as the inner wall of the stirring tank, with only a small gap in between, which can remove the viscous reaction product attached to the tank wall or the solid matter accumulated on the bottom of the tank, and maintain a good transmission. Thermal effect. The peripheral speed of the outer edge of the blade is 0.5~1.5m/s, which can be used to stir Newtonian fluids and pseudoplastic fluids with a viscosity of up to 200Pa·s (see the flow of viscous fluids. Only when stirring high-viscosity liquids, the liquid layer is larger The stagnant zone. 5. The outer diameter of the spiral ribbon agitator is equal to the pitch, which is specially used for stirring high-viscosity liquids (200～500Pa·s) and pseudoplastic fluids. It is usually operated under laminar flow. 6. Magnetic force The Corning digital heater has a closed-circuit knob to monitor and adjust the stirring speed. The microprocessor automatically adjusts the motor power to adapt to the water quality, viscous solution and semi-solid solution. 7. Magnetic heating stirrer Corning digital heating stirrer belt There is an optional external temperature controller (Cat. No. 6795PR), they can also monitor and control the temperature in the container. 8. The folding blade stirrer selects the appropriate stirring according to the physical properties, capacity, and stirring purposes of different media It can play a great role in promoting chemical reaction speed and improving production efficiency. The folding blade turbine agitator is generally suitable for the reaction of gas and liquid mixing, and the rotation speed of the agitator should generally be selected above 300r/min. 9. Frequency conversion The base, support rod, and motor of the double-layer agitator frequency conversion stirrer are fixed as a whole using patented technology. Patented chuck, no looseness, no swing, no falling off, safe and reliable. Chrome-plated support rod, lower thickness and upper thickness, strong rigidity , Reasonable structure. It has the advantages of convenient movement and light weight. It is suitable for all kinds of small containers. 2. What are the functions of the food blender 1. The food blender has two speeds, high and low, regardless of the mixing function or the grinding function. It can play seamlessly and handily. 2. Chopper combination, easily chop meat, vegetables, nuts and coffee beans, and make a variety of delicious food. 3. Powerful accessories, including egg beater, dough hook and mixer, and more These functions are all in one.
