A stirring disk, is respectively uniformly distributed the scraper of axially symmetric extension on the circumference of each stirring disk, each described to scrape
The knife edge of knife is concordant with the place stirring excircle of disk respectively, and the stirring disk on two roots rotor axis is arranged in pairs and in axial direction
Arrangement is mutually staggered, the phase of two column stirring disk upper blades is mutually uniformly staggered；The upper half of the inner cylinder is semicircle,
The lower half of the inner cylinder matches with the rotary knife blade profile of two armature spindle upper blades.
Compared with the existing technology, the present invention achieves following the utility model has the advantages that the stirring disk on a roots rotor axis is clipped in separately
On one roots rotor axis between adjacent two scraper, two column stir the scraper opposite direction rotating on disks and successively interval passes through horizontal plane,
To realize mutually evacuation, avoid collision.The lower half of inner cylinder is the circular arcs of two sections of intersections, makes the section of entire inner cylinder be in
Existing inverted heart-shaped or honey peach shape, liquid phase material are located at double curved bottoms of inner cylinder.High warm is passed through in thermal medium chamber
Medium such as conduction oil, the polymer masses of internal cylinder lumen are heated, and material enters stirring section from material inlet, and one
Side axis are heated stirring to flowing on one side, and polymer volatile matter under high temperature action overflows and generate polymerization reaction, and viscosity is gradually
Increase；With the rotation of stirring disk, two groups of scrapers continue the curved bottom of inswept inner cylinder, constantly agitation material and by material
