The main structure parameters of banbury is rotating speed, diameter, length and the banbury total capacity of rotor; Rotor is the key working part of mixing roll, and its structure is that shape relates to the whether reasonable quality (dispersion and the uniformity coefficient of compounding ingredient in rubber) that directly influences energy consumption, production capacity and sizing material.And the general use of existing continous way banbury is mostly birotor is it is that a plurality of sheet rib bodies are set on the basis of rotor; The rib body is all along rotor pilum spiral extension; Two rotors rotate in opposite directions in the course of work; The rib body of rotor is meshing with each other, and raw material is along with rotor rotation receives promotion, extruding and friction.But the birotor of this structure in use, for mixing shearing rate and the high material of temperature, is difficult to disperse when in banbury, mixing; Mix inhomogeneous; Mixed process is unstable, causes discharging unstable, its inefficiency; Even cause the rotor infringement, influence the production process of whole logistics.
The utility model content
The problem that is difficult to disperse to make its mixing to mixing shearing rate and the high material of temperature; The utility model purpose is to be to provide a kind of and to mix, possess that the continous way banbury of forced conveyance plasticizing capacity and strong mixing ability is with the two mixed rotors of non-engagement; Be suitable for high devolatilization composition, be particularly suitable for the mixing of the material of difficulties in dispersion.
To achieve these goals, the utility model is to realize through following technical scheme:
The continous way banbury is with the two mixed rotors of non-engagement; Comprise a pair of counterrotating rotor block; It is characterized in that; The additive that on every roots rotor body, is respectively equipped with discharge zone, the mass transport section that is arranged on the rotor block other end that is arranged on rotor block one end and is arranged in the rotor block stage casing adds section; Add section at described mass transport section and additive and be provided with the first banburying section that is used for material dispersed and preheating, be provided with the fusion that is used for material, the second banburying section of mixing between said discharge zone and additive add section; The said first banburying section and the second banburying section are the forward and reverse screw thread of double end, are used for material dispersed and preheating; The multiple thread of said mass transport Duan Weifei engagement, said additive adds section and mass transport Duan Jun is shape of threads.
According to above-mentioned continous way banbury with the two mixed rotors of non-engagement, wherein, the screw thread that the forward and reverse screw thread of said double end is made up of forward and many ribs of direction spiral.
With the two mixed rotors of non-engagement, wherein, the cross sectional shape of said discharge zone is oval according to above-mentioned continous way banbury.
With the two mixed rotors of non-engagement, wherein, said additive adds the spiro rod length of the spiro rod length of section less than the mass transport section according to above-mentioned continous way banbury.
With the two mixed rotors of non-engagement, wherein, the reach of the said second banburying section is less than the reach of the first banburying section according to above-mentioned continous way banbury.
The utility model is non-meshing rotor; Through the first banburying section and the second banburying section are set; Its draw ratio can change, and has increased material dispersed and preheating, make difficulties in dispersion material mix, possess forced conveyance plasticizing capacity and strong mixing ability; Be suitable for high devolatilization composition; Be particularly suitable for the mixing of the material of difficulties in dispersion, this kind of and differentiation type rotor thereof can mixing shearing rate and the high materials of temperature, also can mixing low shearing rate and the material more responsive to temperature.
Description of drawings
