Description

A kind of combined type impact agitating device

Technical field:

The utility model belongs to the mixing plant technical field, particularly a kind of combined type impact agitating device.

Background technology:

In the chemical process, the agitator kind of using usually has dasher, turbine agitator, propeller agitator, anchor agitator, gate stirrer, helix(ribbon type) agitator etc.All kinds of agitators are owing to its structure, and differences such as performance make it can be applicable to various operating mode in the Chemical Manufacture respectively.

Dasher can be divided into straight leaf again to be seen and two kinds in hinged joint agitator.The structure of this class agitator and processing are all fairly simple.The ratio d/D of stirrer diameter d and still footpath D is 0.35～0.8, and its running speed is 10～100r/min, is the large-sized low-speed agitator, is applicable to mixing and promotion heat transfer low, the medium-viscosity material, occasions such as the mixing of soluble solids and dissolving.During running based on shearing force.Compare for two kinds with regard to straight leaf and hinged joint, because the blade of hinged joint dasher and Plane of rotation form angle, therefore the axial flow that produces when rotated is greater than straight formula, and its macroscopical mixed effect is better.In actual production, can run into the high situation of the dark liquid of still, this moment, the individual layer dasher was difficult to stir, and the method that adopts is which floor blade of dress usually, staggered at an angle of 90 installation the between adjacent two layers of blade.Because dasher manufacturing and replacing are convenient, therefore be usually used in the operating mode that has anticorrosion and metallic pollution to require in the Chemical Manufacture.

Turbine agitator can be divided into again opens turbine type and disc turbine formula two classes, and every class can be divided into three kinds on straight leaf, hinged joint, palintrope leaf again.Similar with dasher on the turbine agitator contour structures, just blade is more.Stirrer diameter d and the ratio d/D of still footpath D are 0.17～0.5, and rotating speed is 30～500r/min.Higher partial cut effect is arranged during rotation, can obtain the high degree of dispersion micelle, be applicable to that gas-liquid mixed and liquid liquid mix or intensively stirred occasion, be usually used in low medium-viscosity material (＜5 * 10cP).Compare with regard to open-type and disc type, its textural difference causes open-type bigger than disc type circular flow, and axially mixed effect is better.The blade shape of turbine agitator also has a kind of curved leaf except straight leaf and hinged joint are arranged, in stirring, this kind blade extent of damage, consumed power are all low, is applicable to that solid suspension, solid dissolving etc. stir occasion.

Propeller agitator also often is called as propeller mixer.As its name suggests, its blade shape is similar to the screw on the steamer.Stirrer diameter d and the ratio d/D of still footpath D are 0.2～0.5, and rotating speed is higher, is 100～800r/min.Produce bigger axial circulation flow during running, macroscopical mixed effect is better, is applicable to that stirring such as homogeneous liquid mixing is not very strong to be mixed into the stirring occasion of purpose with macroscopic view, be usually used in the low viscosity feed liquid (t～＜2000cP) mixing.

Anchor agitator promptly adds vertical blade on the blade of straight leaf dasher from contour structures.Gate stirrer then adds a crossbeam on anchor agitator.Characteristics of this type of agitator are that stirring outer rim and still wall gap are very little, and d/D is 0.9～0.98, and these characteristics make that material is difficult for producing the dead band when stirring.Rotating speed is 1～100r/min, is low-speed agitator, only produces tangent line stream, and shear action is little, does not have axially and mixes, and is applicable to the high viscosity (＜105cP) stirring of material.As commonly used in the production process of fine chemical product coating, paint, cosmetics to this type of agitator.

Helix(ribbon type) agitator is that the spirality steel band of a constant pitch is fixed on the shaft, and the ribbon outer rim is very near the still wall.During stirring, material rises along the still wall, vertically motion down.Be applicable to (＜105cP) the mixing of high viscosity feed liquid.

The combined type agitator is divided into A, B amphitypy, the A type be usually placed in Type B above, A, B amphitypy all comprise inside and outside two-layer removable agitator.The inside and outside all similar propeller shape of paddle of A type, from clockwise, high back is low before the entoplasm, and ectoplasm is low early and high after.The inside and outside all similar oblique leaf turbine type of paddle of Type B, from clockwise, high back is low before the entoplasm, and ectoplasm is low early and high after.During operate as normal, A type entoplasm compressing liquid moves downward along shaft, and the Type B entoplasm is taken over the compressing of A type entoplasm and liquid down continues compressing liquid to move downward, and to a jar lower, moves upward by Type B ectoplasm promotion liquid again.Equally, A type ectoplasm is taken over the liquid that the transmission of Type B ectoplasm is come, and continues to move upward along tank skin, descends through the compressing of A type entoplasm again, finishes a circulation, near desirable flow pattern.Certainly, the multilayer layout is carried out in the requirement of visual agitated height.

In above-mentioned all agitating devices or the combination agitating device, the main body of liquid flows to and all is tending towards a stable circulation, and the relative motion between the liquid or solid granule therein is limited, and the efficient of stirring is lower.

The utility model content:

The purpose of this utility model provides a kind of can improve the particle degree of scatter, the combined type impact agitating device that stirring efficiency is high.

For achieving the above object, the utility model adopts following technical scheme:

A kind of combined type impact agitating device comprises reactor and agitator, is separately installed with the agitator of direction of rotation at the position, space of two opposition of reactor.
