Description

Segmentation adverse current hinged joint agitator
Technical field
The utility model relates to a kind of agitating device of low-consumption high-efficiency, in being particularly suitable for, the liquid of the liquid mixed system of low-viscosity/liquid dispersion and heat transfer, solid-liquid suspend.
Background technology
Agitating device is extensive in sector applications such as chemical industry, medicine, usually comes the type of choice for use agitator according to physico-chemical property, stirring purpose and the kettle features of shape etc. of agitated medium, and wherein, the viscosity size of medium is a very important Consideration.
Generally speaking, for the stirring system of middle low-viscosity, the conventional agitator that can Gong select has push type, turbine type, oar formula, anchor formula, frame and screw rod/helical-ribbon type etc.Wherein, propeller agitator can form very strong axial circulation and flow, and the radial flow moment only is suitable for the very low stirring system of viscosity; It is large that anchor formula and gate stirrer stir scope, but the shearing force of slowing down when low is little, and whole still circulation ability is very weak, only is suitable for than the high viscosity system or low glutinous system in take crystallization/conduct heat as purpose; Screw rod/helix(ribbon type) agitator is than the anchor gate stirrer, and partial cut and whole still axial circulation increase, but it is also large to stir power consumption, and the mixing efficiency under middle low viscosity system is not high, generally also only uses under the sticking system of height; Oar formula and turbine agitator have certain axial and Radial Flow, and shear action is stronger, and the axial dispersion effect is also good, can be suitable for middle low viscosity liquid-phase system and solid-liquid suspension system, but power consumption is large, and is less economical.In published patent documentation, also just like hinge paddle type stirrer, be called " a kind of hinge paddle type stirrer " utility model technical scheme such as following No. 201120249964.1 name of the patent No., but still have the large and less economical shortcoming of power consumption.
The utility model content
The purpose of this utility model is to provide a kind of segmentation adverse current hinged joint agitator that can solve conventional agitator deficiency of existence in middle low viscosity stirring system is used.
The technical scheme of taking for achieving the above object is: a kind of segmentation adverse current hinged joint agitator is made of root oar, end oar, blade connection and wheel hub.Root oar and end oar adopt dull and stereotyped, form with specific crooked radian and radius compacting, and blade connection is slotted according to the bending shape of segmentation blade.
As preferred version of the present utility model, the blade of agitator evenly distributes, and quantity is generally 2-4, preferably two.
As preferred version of the present utility model, described segmentation adverse current hinged joint agitator places kettle, and the still of kettle directly is made as DI, the oar of agitator footpath Dj is 40 ~ 98% of still footpath DI, when kettle during with baffle plate, and preferred 40 ~ 60%, when kettle during without baffle plate, preferred 90 ~ 98%; The oar footpath D1 of root oar is 60 ~ 80%, preferred 65 ~ 70% of oar footpath Dj; The length L of end oar is 8 ~ 20%, preferred 12 ~ 15% of oar footpath Dj; The length L of the oar footpath Dj of agitator, the oar footpath D1 of root oar and end oar can be adjusted according to the requirement of stirring operating mode and stirring purpose;
As preferred version of the present utility model, the blade width b1 of the root oar of agitator is 5 ~ 20%, preferred 12% of agitator oar footpath Dj; Root oar radius bend r1 is 10 ~ 20%, preferred 15% of agitator oar footpath Dj; The angle α of root oar placed side and horizontal plane is 30 ~ 60 °, preferred 45 °; Root oar blade width b1, root oar radius bend r1 and root oar angle α can adjust according to the requirement of stirring operating mode and stirring purpose;
As preferred version of the present utility model, the blade width b2 of the end oar of agitator is 3 ~ 15%, preferred 8% of agitator oar footpath Dj; End oar radius bend r2 is 10 ~ 20%, preferred 15% of agitator oar footpath Dj; The angle β of oar placed side, end and horizontal plane is 30 ~ 60 °, preferred 45 °; End oar blade width b2, end oar radius bend r2 and end oar angle β can adjust according to the requirement of stirring operating mode and stirring purpose;
As preferred version of the present utility model, described agitator is generally multi-layer configuration and uses, and is 90 ° between the adjacent layer and staggers.Interlamellar spacing S is 30 ~ 120%, preferred 50 ~ 70% of agitator oar footpath Dj.
The design principle of the segmentation adverse current hinged joint agitator that the utility model provides is that during described agitator rotation, the root oar of blade and end oar advance liquid respectively toward opposite direction, impel liquid to form axial circulation, possess the Field Characteristics of pusher blade.Because blade width is narrower, described agitator is generally multilayer and uses, and stirrer combination is similar to again a discrete ribbon-screw impeller.Therefore, described agitator is suitable for low, middle viscosity liquid system, is particularly suitable for the operation in transition region basin.In the transition region basin, blade nearby has little turbulent area, occasion in multi-layer configuration, the turbulent area of the agitator between adjacent layer can be coupled together, form the axial circulation in the whole still scope, therefore have the mixing efficiency suitable with ribbon-screw impeller, and its power levels number is much smaller than ribbon-screw impeller, therefore the standby efficient mixed effect of described mixing tool; In addition, the blade of described agitator is pressed into arc according to special bending rule, and fluid can further reduce the mechanical loss of described agitator through round and smooth passing through of its when surface.
Another beneficial effect of the segmentation adverse current hinged joint agitator that the utility model provides is, in middle low-viscosity zone, and the stirring system that described agitator can change applicable to the operational process of craft medium viscosity, this is that conventional agitator can not be compared; Secondly, when the operation liquid level in the still changed, the combination of the multi-layer configuration of described agitator also can provide stable mixing and dispersion effect.
