Description
Technical field
The present invention relates to a kind of agitating device, belong to industrial application.
Background technology
Agitating device generally comprises motor, and the swingle that motor connects, be arranged on the stirrer paddle composition on swingle in addition, agitating device effect makes liquid, the mixed uniformly equipment of gas medium forced convection, most of agitating devices of current industrial utilization are all that structure is single, and when stirring the larger liquid medium of density, mixing effect is bad, and the service life of agitating device parts is shorter.
The object stirred: Liquid-liquid mixing, gas-liquid mixing and solid-liquid mix.The influence factor stirred has several as follows:
1) type of agitator, size and rotating speed have impact to the distribution of power of agitator between overall flow and turbulence pulsation.
2) the stirring viscosity of different medium viscosity refers to and the resistance capabilities that fluid convection is dynamic is called dynamic viscosity.Fluid, when flowing, is divided into laminar flow, transition flow, turbulent flow three kinds of states, and determines the principal element of these three kinds of states and the viscosity of fluid.
3) internals stirred particularly impeller, guide shell, baffle plate etc. is also the key factor that impact is stirred.
Other
The motion of liquid in tank diameter, is divided into overall flow and turbulence pulsation from yardstick.The flow of overall flow is called internal circulating load, adds the degree of mixing well (see mixability) that big cycle volume is conducive to improving micromixing.Speed when intensity and the fluid of turbulence pulsation leave agitator is relevant, strengthens turbulence pulsation and is conducive to reducing to separate yardstick and segregation intensity.Different processes has different requirements to these two kinds of flowings.The dispersion of drop, bubble, needs strong turbulence pulsation; The even suspension of solid particle, depends on overall flow.During stirring, the distribution of energy in these two kinds flowings, is the major issue in agitator design.
When stirring the mixture, the density contrast of two-phase, viscosity and interfacial tension have a significant impact stirring operation.Density contrast and interfacial tension less, system is more easy to reach stable dispersion; Viscosity is more unfavorable for more greatly forming good circulating and enough turbulence pulsations, and consumes larger power of agitator.
The motion of tank diameter inner fluid is complicated single-phase flow or multiphase flow.The stirring of non-newtonian fluid, the rule having some special in flow regime and power consumption.The measurement of tank diameter inner fluid flow parameter, the expectation of power of agitator, and the amplification method etc. of agitating device, be all mixing theory research and engineer applied in important topic.
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, and in every 1cm2 plane, the size of required shear stress, is called dynamic viscosity, in units of Pas.Viscosity is an attribute of fluid.When fluid flows in pipeline, there are laminar flow, transition flow, turbulent flow three kinds of states, equally also there are this three kinds of flow regimes in mixing plant, and one of major parameter determining these states are exactly the viscosity of fluid.In whipping process, it is generally acknowledged viscosity be less than 5Pa/s such as, for low viscosity fluid, water, castor oil, maltose, jam, honey, lubricating oil heavy oil, low slimy milk liquid etc.; 5-50Pa/s's is medium viscosity fluids, such as ink, toothpaste etc.; 50-500Pa/s's is high viscosity fluid, such as chewing gum, plastisol, solid fuel etc.; Be greater than 500Pa/s for extra-high rheid such as: rubber composition, plastic melt, organosilicon etc.For low-viscosity media, fluid around just can be driven to circulate with the high-revolving agitator of minor diameter, and at a distance.And the fluid of high viscosity medium is quite different, direct agitator is needed to promote.Be applicable to low impeller that is sticky and middle rheid and have paddle, open turbine formula, push type, long slender lobule propeller type, orbital, Bu Lumajinshi, sheet frame paddle, three leaf swept-backs, MIG formula etc.Be applicable to high impeller that is sticky and extra-high rheid and have helical-ribbon type impeller, screw, anchor formula, frame, propeller type etc.Some fluid viscosities carry out with reaction and change, and just needs can be applicable to the impeller in wide viscosity field, as general energy formula impeller etc.
As the patent of invention in publication number to be CN103100345A publication date be May 15 in 2013, this agitator comprises the first blade is connected the device clutch end that reduces by half shaft with one end, the middle part of the first blade and the other end of shaft are fixedly connected, also comprise the second blade, be socketed in sleeve and the motor that is fixed on shaft that shaft slides along shaft, the output of motor is connected with the expansion link for push-and-pull sleeve, one end of second blade and the end points of the first blade hinged, be hinged with adjusting rod between the other end of the second blade and sleeve; This patent can regulate mixing position, and make liquid agitation even, but its blade is shorter, does not reach good stirring, secondly, the second blade quantity is also more, and the resistance of stirring strengthens, and adds cost.
Open text CN104014268, date of publication is the patent on September 3rd, 2014, propose a kind of agitator, comprise the blade be connected with motor by swingle, lower end and a supporting seat of described swingle abut against, supporting seat there is base, base upper end is provided with the support bar being vertically to horizontal plane, the external wall of upper portion of support bar is provided with screw thread, screw thread is set with the nut adjusting described support bar height, agitator when rotated, non-loosening, without waving, the advantage and blade can not come off etc., but blade design is too single, during agitated liquid, mixing power lacks, this patent is when the lightweight conveniently moving of pursuit, the effect stirred also is reduced greatly.
Therefore, for existing disclosed technology and practical application, this patent is intended to propose one, and to overcome existing structure design mixing effect undesirable, and mixing time is long, the new solution that energy consumption is large.
