Agitadores Agitaser is a company that has been designing and manufacturing industrial agitators since 1942. Our expertise in the treatment of liquids.

Introduction to agitator design:

Agitators are machines used in industries for mixing fluids. In industries mixing of fluids is necessary for many chemical processes. It may include mixing of liquid with liquid, gas with a liquid, or solids with liquid. Mixing is accomplished by the rotating action of an impeller in the continuous fluid. Type of fluid and its physical state, the degree of agitation and geometry of vessel are key factors in the design and selection of agitator components.Here we will discuss the design of agitator vessel based on practical data inputs as given below:

Solution:

Step-1: Power calculations and selection of motor

For required power calculations, selection of the type of impeller is very important to achieve required agitation power. Selection of impeller is done based on application and type of flow. Flat paddle, turbine, anchor type, pitched blade impellers are used most commonly. For given type of agitation flat paddle impeller is used as given below:After selection of impeller dimensionless number Reynold’s number is calculated as given belowRe = ρ*N*d⁵/ µFrom generic agitator curve, as shown in Fig.1, impeller power number is calculated based on calculated Reynold’s number.Fig. 1 – Power number against Reynolds number of some turbine impellers [Ref. Bates, Fondy, and Corpstein, Ind. Eng. Chem. Process. Des. Dev. 2(4) 311 (1963)]Based on impellers selected the layout of the shaft is done as shown in Fig.2.Fig.2 Agitator assembly layout

Agitator Design Calculation

Step 2: Design of shaft

Design of solid shaft subjected to shear stressFor selected motor power rated torque and maximum torque is calculated as given below:Rated torque: Tr = P*4500 / 2*π*NMaximum torque: Tm= (1.5 to 2.5) TrTherefore, solid shaft diameter is calculated byTm = π* ζ*ds³/16

Step:3 Design of solid shaft subjected to pure bending

Maximum bending force is assumed to be acting at the point of jamming i.e. 0.75 of maximum agitator radius from the axis.Maximum bending force Fm = Tm/0.75*rMaximum bending moment Mm= π*бb*ds³/32

Step:4 Design of solid shaft subjected to bending and twisting

According to maximum shear stress theory for ductile material, equivalent twisting moment is calculated asTe = √(Mm²+Tm²) = π* ζ*ds³

/16According to maximum normal stress theory for brittle material, equivalent bending moment is calculated asTe = ½ ( Mm+√(Mm²+Tm²) ) = π*бb*ds³/32Larger of all calculated diameters is considered as the minimum required diameter of the shaft. Therefore, selecting shaft diameter of 100mm, the shaft is checked for critical speed.

Step:5 Design of solid shaft based on critical speed

Maximum deflection (∆) due to bending force and corresponding critical speed (Nc) is calculated as follows,∆ = WL³

/ 3EINc = 946/√∆Agitator should be designed to operate at less than 70% of the critical speed. Since selected 100mm dia. shaft is failing at critical speed, select next standard shaft of diameter 120mm and perform the calculations for critical speed.

Thus required solid shaft diameter is 130mm.
