Description
Technical field
The utility model relates to a kind of stirring system, especially relates to a kind of stirring system that is provided with constant speed stirrer, is applicable to fields such as medicine, chemical industry, food.
Background technology
Agitator is to make liquid, gas medium forced convection and mixed uniformly device.The type of agitator, size and rotating speed, all influential to the distribution of power of agitator between overall flow and turbulent flow pulsation.Generally speaking, the power division of turbine agitator is favourable to the turbulent flow pulsation, and propeller mixer is favourable to overall flow.For the agitator of same type, under the identical condition of power consumption, major diameter, slow-revving agitator, power mainly is consumed in overall flow, helps macroscopic view and mixes.Minor diameter, high-revolving agitator, power mainly are consumed in the turbulent flow pulsation, help microcosmic and mix.The amplification of agitator is the challenge relevant with technical process, so far can only be through experience amplification step by step, and the amplification criterion according to obtaining is extrapolated to commercial scale.
Viscosity is meant the resistance capabilities that fluid convection is moving, and it is defined as: when liquid flowed with the speed of 1cm/s, the size of required shear stress was called dynamic viscosity on every 1cm2 plane, is unit with Pa/s.Viscosity is a kind of attribute of fluid.When fluid flows, laminar flow, transition flow, three kinds of states of turbulent flow are arranged in pipeline, equally also have this three kinds of flow regimes in the mixing plant, and one of major parameter that determines these states is exactly the viscosity of fluid.In whipping process, it is generally acknowledged the be low viscosity fluid of viscosity, for example: water, castor oil, maltose, jam, honey, lubricating oil heavy oil, low slimy milk liquid etc. less than 5Pa/s; 5-50Pa/s's is medium viscosity fluids, for example: printing ink, toothpaste etc.; 50-500Pa/s's is high viscosity fluid, for example chewing gum, plastisol, solid fuel etc.; Greater than 500Pa/s be the extra-high-speed rheid for example: rubber composition, plastic melt, organosilicon etc.For the low viscosity medium, the fluid circulation around just driving with the high-revolving agitator of minor diameter, and distant place extremely.And the fluid of high viscosity medium is quite different, needs directly to promote with agitator.Be applicable to that low sticking impeller with middle rheid has the oar formula, opens turbine type, push type, long slender lobule propeller type, disc turbine formula, Bu Lumajinshi, sheet frame oar formula, three leaf swept-backs, MIG formula etc.Be applicable to that high sticking impeller with the extra-high-speed rheid has helical-ribbon type impeller, screw, anchor formula, frame, propeller type etc.The fluid viscosity that has carries out with reaction and changes, just need with the impeller that can be fit to wide viscosity field, as general can the formula impeller etc.
The design selection of agitating device is combined closely with stirring operation purpose.Various whipping process need be moved by different agitating devices and realize; At first will be when design selection according to technology to stirring the purpose and the requirement of operation; Confirm agitator pattern, motor power (output), mixing speed, select each parts such as reductor, frame, shaft, axle envelope then.According to process conditions, stir purpose and requirement, select the agitator pattern, should fully grasp the dynamic characteristics of agitator and flow regime that agitator is produced and the causality of various stirring purposes when selecting the agitator pattern in whipping process; The flow regime that in whipping process, is produced according to determined agitator pattern and agitator; Technology is to the control requirement of the time of mixing, sinking speed, decentralization; Through laboratory facilities and computer simulation design, confirm motor power (output), mixing speed, stirrer diameter; According to motor power (output), speed of agitator and process conditions, from reductor type selecting table, select to confirm the reductor type.If select reductor according to the real work moment of torsion, then the real work moment of torsion should be less than the reductor allowable torque; According to installation form and structural requirement, design alternative shaft structural shape, and its intensity, rigidity are examined in the school; According to supporting and antivibration condition, determine whether to dispose aiding support.In above type selecting process, the combination of agitating device, configuration can be with reference to (agitating device design alternative schematic flow sheets), and connecting critical size between each parts in the layoutprocedure is the spindle nose size, interchangeable in principle, the combination of each parts of spindle nose consistent size.Motor can't keep stabilized (steady-state) speed after work a period of time, make mixing effect be affected.
