Description
Technical field
What the present invention relates to is a kind of rotor structure, and what be specifically related to is that a kind of continous way banbury is with the two mixed rotors of material.
Background technology
Banbury is one of capital equipment of using of plastics compounding, can be divided into two types of batch (-type) and continous ways by operation principle.It is made up of banburying chamber, rotor, floating weight (material pressing device), following top bolt (device for discharging), heating-cooling device and transmission system etc.Its operation principle is: compound gets into banburying chamber by loading hopper; At gap, rotor and the banburying chamber inwall gap of two counterrotating rotors, rotor and up and down in the gap of top bolt; Receive shearing, kneading and the rubbing action of continuous variation, make plastics give birth to heat and plastify, and mix.
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; Be 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.
Summary of the invention
The problem that is difficult to disperse to make its mixing to mixing shearing rate and the high material of temperature; The continous way banbury that the present invention seeks to be to provide a kind of and mix, possess 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 present invention realizes 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 screw-like.
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 present invention is non-meshing rotor; Through the first banburying section and the second banburying section are set; Its draw ratio can change; Material dispersed and preheating have been increased; 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
Describe the present invention in detail below in conjunction with the accompanying drawing and the specific embodiment;
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with the specific embodiment, further set forth the present invention.
Referring to Fig. 1; Continous way banbury of the present invention is with the two mixed rotors of non-engagement; It is non-meshing rotor; Comprise a pair of counterrotating rotor block 1; On every roots rotor body 1, be respectively equipped with the discharge zone E that is arranged on rotor block 1 one ends, an additive adding section C who is arranged on the mass transport section A of rotor block 1 other end and is arranged on rotor block 1 stage casing; Between mass transport section A and additive adding section C, be provided with the first banburying section B, be used for material dispersed and preheating; Discharge zone E and additive add between the section C and are provided with the fusion that is used for material, the second banburying section D that mixes; The first banburying section B and the second banburying section D are the forward and reverse screw thread of double end, are used for material dispersed and preheating.
In the present embodiment, the screw thread that the forward and reverse screw thread of double end is made up of forward and many ribs of direction spiral, the reach of this second banburying section D is less than the reach of the first banburying section B, the dispersion of increase and preheating.Above-mentioned mass transport section A is the multiple thread of non-engagement, that is, the non-engaging twin-screw section mainly is a mass transport; Said additive adds section C and mass transport section A all is screw-like, and additive adds the spiro rod length of the spiro rod length of section C less than mass transport section A, and additive adds section C through additive and adds.The spiral shell rib 2 of the mass transport section A of present embodiment is provided with four, and the spiral shell rib 12 that additive adds section C is provided with three.
