Description
Technical field
The utility model relates to a kind of turbine stirrer, especially the double-deck disc turbine agitator of a kind of enclosed, with the device of insoluble matter emulsifyings such as solid and liquid, it is applicable to that the liquid viscosity scope is 0-3000mPa.s when specifically using materials such as dealing with stearate.
Background technology
Agitator claims paddle or agitator arm again, is the critical component of stirred reactor.Its function provides process energy needed and suitable flow regime.Several agitators commonly used have dasher, propeller agitator, turbine agitator.
Dasher and propeller agitator can make the temperature of charge homogeneous, prevent the solid sedimentation, prevent that liquid liquid from separating, and turbine stirrer is to use wider a kind of agitator, can finish nearly all stirring operation, and can handle the very wide fluid of range of viscosities.By being installed at centrifugal disc, 2～4 blades straight or bending constituted.The ratio of the external diameter of blade, width and height is generally 20:5:4, and peripheral speed is generally 3～8m/s.Turbine causes the Radial Flow of height turbulence when rotated, is applicable to dispersion and the liquid liquid phase reaction course of gas and immiscible liquid.
Turbine agitator is divided into the disc turbine agitator and opens turbine stirrer; Can be divided into straight leaf and oblique sheet leaf again according to impeller.Turbine stirrer speed is bigger, 300～600r/min.The major advantage of turbine stirrer is that stirring efficiency is higher when energy consumption is little, stirs to produce very strong radial flow.Therefore it is applicable to emulsion, suspension etc.
Turbine agitator has bigger shearing force, can make the very thin of fluid micellar dispersion, is applicable to that low viscosity arrives the mixing of medium-viscosity fluid, liquid-liquid dispersion, liquid-solid suspension, and promotes good heat transfer, mass transfer and chemical reaction.
We make incompatible or are being difficult for molten liquid, solid and powder additive etc. at present, common agitator moment uniform, fine dispersion and emulsion the time often stir speed (S.S.) is not enough, can make the size ratio of solid particle bigger, under the effect of emulsifying agent, can not reach and evenly spread in the liquid, thereby can't reach the emulsifying effectiveness that we want.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of energy savings, mixing evenness is good and be applicable to the disc turbine agitator that the stearate dispersion liquid prepares.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of disc turbine agitator, it comprises tank diameter, shaft and is located at disk on the shaft, its key technology is: described disk comprises the turbine that six straight shape blades constitute and is located at hoop closure plate on upper and lower two end faces of turbine, described disk is upper and lower to be arranged two-layerly, is provided with 4 axial baffle plates at described tank diameter inwall.
Described tank diameter inner diameter D is 400-500 ㎜, and barrier width is 40-50 ㎜, and liquid level H is 60-700 ㎜ in it.
The beneficial effect that adopts technique scheme to produce is: the utility model is provided with enclosed double-deck disk, and increased baffle plate, shear ability increases, improved the liquid flow field in the container, be of value to the dispersion and emulsion of solid particle in water, in being applicable to, high-speed stirred, avoided forming in jar (being tank diameter) whirlpool, weaken the slipstream of reactant liquor, the ratio of height to diameter that is applicable to tank diameter is 1.0-2.0, shear ability is big, makes the particle diameter of solid particle reach Nano grade, is a kind of good combination property, energy-efficient, stability of rotation, simple in structure, the novel agitator of low cost of manufacture.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of turbine of the present utility model;
Among the figure 1, shaft; 2, turbine; 3, baffle plate; 4, tank diameter; 5, ring seal plate; 6, straight shape blade.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Referring to accompanying drawing 1, this is novel to comprise tank diameter 4, shaft 1 and is located at the disk 2(of shaft 1 lower end or is agitator disk), described disk comprise the turbine 2 that six straight shape blades constitute and be located at turbine 2 upper surfaces and following two end faces on two hoop closure plate 5, described disk arranges two along shaft 1 is upper and lower, be provided with 4 axial baffle plates 3 in described tank diameter 4 inside, baffle plate 3 arranges perpendicular to tank diameter 4.
Present embodiment tank diameter internal diameter is D=476mm, and liquid level is got H=1.4D=666.4mm, and barrier width is got d=0.1D=47.6mm.Referring to accompanying drawing 1 and accompanying drawing 2 described turbines 2 by six straight shape blades 6, described six straight shape sheets 6 are spaced, rounded shaft 1 center that is centered around, on the turbine 2, under two rings shape closure plate 5 is arranged, two enclosed disks cooperate up and down, the stirring efficiency height, in the tank diameter 4 of cylindrical tube shape, uniform four baffle plates 3 all around, produce high jet in the turbine district, maximal rate appears at turbine 2 ends, and radial jet is being carried surrounding fluid secretly and struck baffle plate 3 in flow process after, radially current drainage is divided into two parts, a part upwards flows along baffle plate 3, a part flows downward, and at this moment, has 4 circulations in the tank diameter 4, there is apparent in view zoned phenomenon between the two-layer disk, form parallel popularly, whole basin does not have obvious dead band, liquid is mixed reach full and uniform.
When two disk spacings hour, last lower disc suppresses mutually, and the fluid center of vorticity extends to cell body is peripheral, and middle two collar vortexs are extruded, and the shearing force that rotating fluid produces makes on the surface of adjacent with it surrounding liquid and produces many small eddy current, and eddy current and turbulent flow are also deposited.This eddy current and turbulent flow and deposit can promote locally to mix, caused mass transfer and heat transfer effect such as interface renewal between out-phase, and the process of the division of bubble and drop, dispersion.
The utility model is particularly useful for stearate and is dispersed in the water, makes the grain diameter of stearate reach Nano grade by shear action and powerful the stirring, and the emulsification that is conducive in water disperses.
