A device for forcing convection and uniform mixing of liquid and gaseous media. The type, size, and speed of the agitator have an effect on the distribution of the agitation power between the overall flow and the turbulent pulsation. Mechanical equipment that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, the contact surface area of the materials can also be increased to promote chemical reactions; it can also accelerate physical changes.
① Rotary propeller agitator It consists of 2 to 3 propelling propeller blades (Figure 2), with a high working speed, and the peripheral speed of the outer edge of the blade is generally 5 to 15 m / s.
② Turbo type agitator By installing 2 to 4 straight or curved blades on a horizontal disc Made up.
③ Paddle Agitator There are two types of flat paddle and oblique paddle. The flat paddle agitator consists of two straight paddles.
④ Anchor mixer The shape of the outer edge of the blade must be consistent with the inner wall of the stirring tank, with only a small gap between them. It can remove the viscous reaction products attached to the tank wall or the solids accumulated on the bottom of the tank, and maintain good heat transfer effect.
⑤ Spiral Stirrer The outer diameter of the spiral ribbon is equal to the pitch. It is specially used for stirring high-viscosity liquids (200-500Pa · s) and pseudoplastic fluids. It is usually operated in laminar flow.
⑥ Magnetic stirrer The microprocessor automatically adjusts the motor power to adapt to water quality, viscous solutions and semi-solid solutions.
⑦Magnetic heating stirrer
⑧Folding leaf agitator Choosing the corresponding agitator according to the physical properties, capacity, and stirring purpose of different media can greatly promote the speed of chemical reactions and improve production efficiency. Folded-blade turbine stirrers are generally suitable for gas-liquid phase mixing reactions, and the number of revolutions of the stirrer should generally be selected above 300 r / min.
⑨Inverter double-layer mixer The base, support rod and motor of the inverter mixer are fixed into one with patented technology
⑩Side-in mixer The side-entry mixer is equipped with a stirring device on the side wall of the equipment cylinder. The agitator on the mixer is usually an axial flow type. There are many push-type mixers. Under the condition of consuming the same power, the highest mixing effect can be obtained. . Widely used in desulfurization, denitrification, and various large tanks or tanks. Especially in large storage tanks or tanks, one or more side-entry mixers are used to work together, and a good mixing effect can be obtained with low energy consumption.
