Abstract
The utility model discloses a pulse screw millstone-type mixer, which is used to complete breakage, mixing and reactive processing for a polymer and a filling. The utility model is a whole process in which a machinery pulse dynamic field is generated from an electromagnetism filed and a vibration exciter is induced into a processing course. The circulation convey and cut-squeezing of the polymer and the filling is implemented by the screw edges of the internal screw and the external screw, as well as the end face milling prism of the millstone and the external screw rod so as to raise mixing-milling effect and chemical reaction efficiency of material. The rotation speed of the external screw is adjusted to change the accepted intensity of cutting and squeezing between the external screws and a hopper, the internal screw and the external screw, a mill and an external screw end. By the regulation of the vibration frequency and the range, a pulse cutting and squeezing are implemented so that mixing and scattering and even grain location of the material are intensified for valid cutting and mixing of the polymer and the filling, and the control of product structure and physical chemistry performance.
Description
Affiliated technical field
The utility model relates to a kind of mixed with polymers processing unit (plant), especially polymer and filler is carried out processing unit (plant) broken and mixing and reaction, more specifically to a kind of pulsation screw rod abrasive disk type blender.
Background technology
At present, the capital equipment of realizing polymer batch mixed and chemical reaction is a blender, and material is by the shear action between rotor and the mixing chamber, make polymer and filler fusion, mixing, disperse or react, goods have good physical and mechanical properties, and production efficiency is higher.But this processing method is owing to the limitation of structure, and the dispersion of filler in polymer is insufficient, and thermograde is big, and the mixed milling effect is bad, and chemical reaction rate is difficult to control, quality of item instability.
Summary of the invention
In order to overcome refinement in polymer of the filler in the conventional hybrid device, processed and uniform poor, the temperature of charge skewness, chemical reaction rate is difficult to control and the restriction narrow to processing materials adaptability, the utility model provides a kind of pulsation screw rod abrasive disk type blender, introduce the mixing and reaction processing overall process of polymer by the field of force of will pulsing, changed the mechanism of traditional polymer hybrid process, adopt the combination of inner screw and external screw rod to realize the cyclic process of material, material moves along helical trajectory in mill end face wedge-shaped slot simultaneously, be subjected to strong pulsation shear extrusion effect, thereby make that the stickiness and the elasticity of polymer melt reduces in process, mixing of materials is mixing effect improved with chemical reaction.
The technical scheme that its technical problem that solves the utility model adopts is: based on Electromagnetic Dynamic processing and forming theory, the Polymer Processing overall process is introduced in the mechanical pulse field of force of electromagnetic field and vibrator generation, broken through the notion of traditional polymer stable state moulding, utilize the spiral shell rib of inner screw and external screw rod and the end face mill rib of mill and external screw rod, realization is to the circulation conveying and the shear extrusion of polymer and filler, simultaneously to pressure in mixing and the course of reaction, temperature, rotating speed, vibration amplitude, the online complete monitoring of vibration frequency, this pulsation shear extrusion technology can improve the mixed milling effect and the chemical reaction efficiency of material.Inner screw and fixed millstone in the barrel connect firmly, and fixed millstone adopts screw attachment on barrel, and external screw rod and armature utilize sliding supported condition on the shell of vibrator, and barrel and magnet exciting coil are fixed on the vibrator shell by screw attachment.The rotating speed of regulating external screw rod can change material and be subjected to the shear extrusion action intensity between external screw rod and barrel, inner screw and external screw rod and fixed millstone and external screw rod end face, regulating the vibration frequency and the amplitude of external screw rod can realize the pulsation shearing and push and strengthen mixing of materials and disperse, granularity is consistent more, Temperature Distribution is more even, reaches the purpose of effective shear-mixed, control goods morphosis and the physical and chemical performance of polymer and filler.
The beneficial effects of the utility model are, can carry out fragmentation and mixing and reaction processing to polymer and filler, simple in structure, energy consumption reduces, chemical reaction course is controlled easily, the morphosis and the performance of this pulsation screw rod abrasive disk type blender institute processing materials are good, for the development high-performance polymer provides new way.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a structural map of the present utility model.
1. fixed millstones among the figure, 2. inner screw, 3. external screw rod, 4. heater, 5. barrel, 6. magnet exciting coil, 7. armature.
The specific embodiment
In the drawings, when external screw rod (3) rotatablely moves as circumference,, produce relative motion in barrel (5) thereby make between fixed millstone (1) and inner screw (2) and the external screw rod (3) because the adhesive effect of magnet exciting coil (6) and armature (7) produces axial pulse.Rotating speed by frequency converter change motor can make the rotating speed of external screw rod (3) change in a big way.By changing magnet exciting coil (6) current's intensity and change frequency, the vibration amplitude and the frequency of external screw rod (3) are adjusted in relative broad range.Polymer is pressed different ratio requirement inputs, closed charge door after the material compacting with filler by charge door.By switching on and off and the flow velocity of cooling medium of thermocouple control heater (4), realize accurately control institute processing materials temperature.
