design of vertical shaft agitation tank

vertical agitators fluidmixthe vertical agitators are equipment with a shaft which end side is near the bottom of the tank and through one or several mobiles made great part of processes of the industry in general: mix, dispersion, homogenization, suspension, etc. vertical industrial agitator nbi inoxpa agitatorsthe agitators are normally installed inside the tank either centrally with current deflectors, or offset to prevent the rotation of the stirred product. the rotation of the propeller makes the fluid flow to the bottom and then up to the surface of the product along the walls of the tank. the effect is promoted if the bottom of the tank is curved. process engineering mind mixer mechanical design chemical apr 18, 2006 · the shaft length to support may exceed the shaft length inside the tank because the nearest support bearing may be in the drive or seal above the tank mounting or flange. multiple impellers require separate bendingload calculations for each, using the fraction of the motor power at each impeller and at the appropriate shaft length, and review on design of agitator to optimize its performanceii. shaft design the shaft is attached to the agitator and may be located in horizontal, vertical or angular position. a. power requirement for agitation: power required to operate an agitator depends on several factors such as the properties of the liquid, agitator type and size, the tank or vessel size and speed of agitation. n p chapter 21 mechanical design of mixing equipment1250 mechanical design of mixing equipment figure 211 directdrive portable mixer. (courtesy of lightnin.) mixers are mounted on the vertical centerline of a tank with bafes, but may be offcenter or offcenter, angle mounted. longer shafts and larger impellers cause more severe loads on topentering mixers than portable mixers. a typical 1mb d. s. dickey, j. b. fasano 88 2004are you using the right tank design for your industrial viscosity is the most critical factor in tank design for liquid blending. when the viscosities are waterlike (e.g., whiskey, beer, wine, window cleaner, mouthwash), the flow is turbulent. almost any mixing tank configuration is allowed. it can be short and squatty or tall and skinny. it can be round, square, rectangular, horizontal cylindrical or even irregularly shaped. although you can use just about any tank design for blending waterlike liquids, the tank geometry determines the placement and number of industrial mixer(s) for effectiveblending. as an example, for a typical miscible liquid blending application, you cant place one industrial mixer close to the end of a long, horizontal cylindrical mixing tank (figure 1) and expect to effectively agitate the vessel contents. odd shaped mixing tanks often require more than one industrial mixer as do very shallow pits and sumps. when you are blending liquids of significant viscosity, the flow is laminar (i.e., not turbulent). in th see full list on proquipinc the optimum tank design for solids suspension mixing applications is round and has an aspect ratio of about 1:1. it must either be baffled with the industrial mixer on center or the mixer can be angleoffset mounted. a center mounted industrial mixer in an unbaffled tank does not effectively suspend solids. straightvertical offset mixers in unbaffled tanks leave a significant heal of solids in one sector of the tank floor. angleoffset mixers are generally restricted to relatively small volumes although we have used them successfully in 25,000 gallon tanks. it is important to recognize that solids can easily be suspended to a height of about 85% of the tank diameter with a single agitator impeller. however, even when multiple agitator impellers are used, it is generally impractical to suspend solids higher than about 1.4 times the tank diameter, and it is nearly impossible to suspend them more than twice the tank diameter in a conventional tank. if these constraints are unacceptabl see full list on proquipinc click the following links for more information about liquid blending and solids suspension mixing applications. if you need help with mixing tank design for your liquid blending or solids suspension application, email [email protected] or call us at 3304681850. part two of our blog series on tank design addresses several more mixing applications including dispersion, dissolution, emulsification, heat transfer and several others. print version see full list on proquipinc three important considerations for mixing biomaterials how to use process objectives to compare industrial mixers should you use impeller pumping rate to compare industrial mixers? when to use a steady bearing in your industrial mixer shaft design 3 reasons steady bearings are not used in industrial mixer shaft design how to prevent fatigue failure in the gearbox shaft of your industrial mixer 5 things to consider when designing an industrial mixer shaft how to stop your industrial mixer from shaking 3 ways viscosity affects your industrial mixer specifications and mixing process [contactform [email protected] subject=i would like email updates][contactfield label=name type=name required=1/][contactfield label=email type=email required=1/][/contactform] see full list on proquipinc
