Description
Technical field
The present invention relates to a kind of agitating device and stirring means thereof.
Background technology
Agitating device generally comprises motor, and the swingle that motor connects, and is also arranged on stirring on swingle
Mixing blade composition, agitating device effect is to make liquid, the mixed uniformly equipment of gas medium forced convection, current industrial utilization
Most of agitating devices be all that structure is single, and stirring density bigger liquid medium time, mixing effect is bad, and agitating device
The service life of parts is shorter.
The purpose of stirring: Liquid-liquid mixing, gas-liquid mixing and solid-liquid mixing.The influence factor of stirring has the most several:
1) type of agitator, size and rotating speed have shadow to power of agitator distribution between overall flow and turbulence pulsation
Ring.
2) the stirring viscosity of different medium viscosity refers to the resistance capabilities that fluid convection is dynamic, referred to as dynamic viscosity.Fluid exists
During flowing, it is divided into laminar flow, transition flow, three kinds of states of turbulent flow, and determines the principal element i.e. viscosity of fluid of these three state.
3) internals stirred particularly impeller, guide shell, baffle plate etc. are also the key factors of impact stirring.
Other
The motion of liquid in agitator tank, is divided into overall flow and turbulence pulsation from yardstick.The flow of overall flow is referred to as circulation
Amount, adds big cycle volume and is conducive to improving the degree of mixing well (see mixability) of micromixing.The intensity of turbulence pulsation is left with fluid
Speed during agitator is relevant, strengthens turbulence pulsation and is conducive to reducing separation yardstick and segregation intensity.Different processes to this two
Plant flowing and have different requirements.Drop, the dispersion of bubble, need strong turbulence pulsation；The even suspension of solid particle, depends on
In overall flow.During stirring, energy distribution in both flowings, is the major issue in agitator design.
When stirring mixture, stirring operation is had a significant impact by biphase density contrast, viscosity and interfacial tension.Density contrast
The least with interfacial tension, system more easily reaches stable dispersion；Viscosity the biggest be unfavorable for being formed good circulate and
Enough turbulence pulsations, and consume bigger power of agitator.
In agitator tank, the motion of fluid is complicated single-phase flow or multiphase flow.The stirring of non-Newtonian fluid, in flow regime
Some special rules are had with power consumption aspect.The measurement of fluid flow parameters in agitator tank, power of agitator it is expected that with
And the amplification method etc. of agitating device, it is all the important topic in mixing theory research and engineer applied.
Viscosity refers to the resistance capabilities that fluid convection is dynamic, and it is defined as: when liquid flows with the speed of 1cm/s, often
The size of required shear stress in 1cm2 plane, referred to as dynamic viscosity, in units of Pa s.Viscosity is an attribute of fluid.Stream
When body flows in pipeline, there are laminar flow, transition flow, three kinds of states of turbulent flow, mixing plant there is also these three flowing shape equally
State, and one of major parameter determining these states is exactly the viscosity of fluid.In whipping process, it is considered that viscosity is less than
5Pa/s for low viscosity fluid, such as water, Oleum Ricini, maltose, fruit jam, Mel, lubricating oil heavy oil, low slimy milk liquid etc.；5-
50Pa/s for medium viscosity fluids, such as ink, toothpaste etc.；50-500Pa/s for high viscosity fluid, such as chewing gum, plasticising
Colloidal sol, solid fuel etc.；More than 500Pa/s for extra-high rheid such as: rubber composition, plastic melt, organosilicon etc..Right
In low-viscosity media, fluid circulation around just can be driven with the high-revolving agitator of minor diameter, and at a distance.And high viscosity
The fluid of medium is quite different, needs direct agitator to promote.Be applicable to low viscous and the impeller of rheid have paddle, open whirlpool
Slender lobule propeller type wheeled, pusher, long, orbital, Bu Lumajinshi, sheet frame paddle, SANYE swept-back, MIG formula etc..
It is applicable to high viscous and extra-high rheid impeller and has helical-ribbon type impeller, screw, anchor formula, frame, propeller type etc..Some fluids
Viscosity carries out with reaction and changes, it is necessary to being suitable for the impeller in width viscosity field, such as general energy formula impeller etc..
Such as the patent of invention that Publication No. CN103100345A publication date is May 15 in 2013, this agitator includes first
Blade and one end connect the shaft halving device clutch end, the middle part of the first blade connection fixing with the other end of shaft
Connect, also include the second blade, be socketed on shaft the sleeve slided along shaft and the motor being fixed on shaft, motor
Outfan connect have the expansion link for push-and-pull sleeve, one end of the second blade is hinged with the end points of the first blade, the second leaf
It is hinged with adjusting rod between the other end and the sleeve of sheet；This patent can regulate mixing position so that liquid agitation is uniform, but
Its blade is shorter, does not reaches preferably stirring, and secondly, the second blade quantity is the most more, and the resistance of stirring strengthens, and adds into
This.
Disclosure CN104014268, date of publication is in JIUYUE, 2014 patent of 3 days, it is proposed that a kind of agitator, including
The blade being connected with motor by swingle, the lower end of described swingle supports seat with one and abuts against, supports and have base, the end on seat
Seat upper end is provided with the support bar being vertically to horizontal plane, and the external wall of upper portion of support bar is provided with screw thread, and screw thread is set with adjustment
The nut of described support bar height, agitator when rotated, non-loosening, without waving, and blade such as does not comes off at the advantage, but oar
Leaf design is the most single, and during agitated liquid, mixing power lacks, and this patent is pursuing lightweight conveniently moving when so that stirring
Effect is greatly reduced.
Therefore, for existing disclosed technology and actual application, this patent is directed to one and overcomes existing structure to set
Meter mixing effect is undesirable, and mixing time is long, the new solution that energy consumption is big.
