Description
Technical field
The utility model relates to a kind of macromolecular material compounding machinery, particularly a kind of high/the cold kneading unit that stirs.
Background technology
At present the stirring theory of domestic and international various high speed kneaders all is by the structures shape of agitator.The agitator of these high speed kneaders generally adopts oar formula structure.Because the hypotenuse of oar face becomes certain inclination angle with the direction of motion, so when agitator moves,, except that producing the dispersion of horizontal loops streaming, also produce axial shunting simultaneously and disperse for becoming the material of powder state.Material is thrown to the still wall as quick as thought, rise along the still wall friction, thereupon again by the deflection plate baffling to the still center, fall in the formed eddy current in center, thrown to the still wall again, so endlessly, until mixing end.Needed heat is mainly from frictional heat in mixed process for material, and therefore, with under the speed conditions, the volume of equipment is bigger, and its shear stress is higher, and temperature arrising caused by friction speed is higher thereupon.Otherwise after equipment was less than 100 liters, it is very little that its frictional heat can become, when equipment during less than 10 liters, and frictional heat no better than zero.So the high speed kneader below 100 liters when work, can not rely on frictional heat to reach and mix needed mixing temperature, have to provide heat by the electrically heated oil in the still wall chuck.So just cause the still temperature to be higher than the material temperature, the part that molecular weight is low in the material at first adheres to the still wall, causes the component ratio to change, and produces and mixes uneven, the unequal phenomenon of preplasticizing.If do not heat outward and do not adopt, the material in the mixing does not reach the effect of preplasticizing again.One of major reason that Here it is laboratory data and big creation data can not be consistent.
The content of utility model
The purpose of this utility model provides a kind of macromolecular material compounding with the height/cold kneading unit that stirs, it can solve the above problems, can in process, produce higher shear stress, make low capacity testing equipment by frictional heat material is warmed up to preplasticizing temperature (110 ℃); Also can under 200-500 liter capacity state, nanometer grade powder material be carried out pre-dispersed processing.Guarantee that the component ratio mixes, preplasticizing is even.
The purpose of this utility model realizes by following technical scheme.
The utility model height/cold kneading the unit that stirs is characterized in that: it comprises that height stirs machine, discharge gate and cold mixer, and described height stirs machine and interlinks through described discharge gate and described cold mixer;
Described height stirs machine and comprises upper kettle, last main shaft, upper, middle and lower-ranking leaf oar, goes up kettle cover, deflection plate; One end of described upward main shaft extend in the described upper kettle from the bottom of described upper kettle, on described in described upper kettle on the main shaft, be equipped with successively from bottom to top described down, in, last three layers of leaf oar, described upward kettle cover is positioned at the top of described upper kettle, described deflection plate is equipped with on top in described upper kettle, bottom at described upper kettle has end socket, interlinks through the upper end of described end socket and described discharge gate, has water jacket in the outside of described upper kettle;
Described cold mixer comprises lower kettle, leaf oar, lower main axis, following kettle cover, one end of described lower main axis extend in the described lower kettle from the bottom of described lower kettle, described leaf oar is housed on the described lower main axis in described lower kettle, described down kettle cover is positioned at the top of described lower kettle, has the hole and described discharge gate lower end interlinks on described kettle cover down; Outside at described lower kettle has water jacket.
Described height stir machine following, in, two layers of leaf oar are the sheet of symmetry, wherein, the longitudinal cross-section shape of described lower blade is consistent with the respective base cross sectional shape of described upper kettle, hypotenuse on the end of described lower blade has; Have the inclined-plane on described middle period oar, described inclined-plane becomes the inclination angle with the direction of motion; Described upper blade is two fairings that two port claims; Described deflection plate is contained on the kettle cover.The lower surface of described deflection plate is a curved surface,
The refraction angle of described deflection plate lower surface be with on the materials flow of gushing be folded to the eddy current center.
The volume that described height stirs machine is the 200-500 liter, and the volume of described cold mixer is the 350-800 liter, and the speed of mainshaft that described height stirs machine is not less than 4000 rev/mins.
The volume minimum that described height stirs machine can be 2 liters, and the volume of described cold mixer is 6 liters, and the speed of mainshaft that described height stirs machine is not less than 4000 rev/mins.
The water route of the water jacket of described upper and lower kettle outside is spiral helicine.
In the utility model, in three layers of leaf oar in the high speed kneader, following oar effect is that the bottom material is thrown; Middle oar effect is that the middle level material is thrown, and makes between layer and the layer and produces friction; Last oar is two fairings that two port claims, do parallel motion with the still wall, effect is to being thrown to the still wall by following, middle blade, and carry out compaction type along the material that the friction of still wall do is risen and shear, this shear stress is bigger, can produce enough frictional heats material is heated up, be enough to break the agglomerating force of nanometer particle again, and it is carried out pre-dispersed processing.Deflection plate is the curved baffle that covers formula at the operation principle of three layers of leaf oar on being designed to, and its effect is that the material of shearing through the fairing compaction type is rolled over to the eddy current center.The effect of described low speed kneader part is that the high-temperature material that will change over to from the high speed kneader is reduced to normal temperature non-cakedly.The main effect of the water jacket of upper and lower kettle is evenly to control temperature rise rate with spiral helicine cooling water channel.Through experiment, the rotating speed of main shaft can not be lower than 4000 rev/mins, and when being used for the nanometer grade powder dispersion, the rotating speed of main shaft is between 4000-6000 rev/min.
In sum, the utility model has been strengthened to shear and has been disperseed the mixing ability owing to adopt novel leaf oar combination, make small-scale test that 2-100 rises with equipment in also can with data consistent during production of being mixed of industrialization macromolecular material.Equally, this structure also can be given pre-dispersed processing to nanometer grade powder effectively.And can in the identical time, high-temperature material be reduced to normal temperature dispersedly.Thereby solved the problem of lab scale compounding frictional heat difficulty and the pre-dispersed difficulty of nanometer grade powder.The low capacity that the utility model the is suitable for material usefulness that is mixed.
