During the utility model work, the melt with certain viscosity enters into housing inner chamber from material inlet, under the drive of shaft, upwards taken up, the free-falling of melt gravitate also starts film forming, polymerization reaction take place in the vacuum environment of housing inner chamber, deviate from micromolecular volatile matter, melt in housing intracavity bottom is constantly taken up under the disturbance of mouse cage, melt flows along housing inner chamber to material outlet simultaneously, because housing inner chamber is tapered, all melts is easy to be subject to Action of Gravity Field and flows to material outlet, thereby make melt can local clustering phenomena not occur at housing inner chamber, finally obtain desirable homogeneous phase product.Compared with prior art, advantage of the present utility model is: all high viscosity polymer melts of housing inner chamber are easy to be subject to Action of Gravity Field and flow to material outlet direction, be aided with the continuous disturbance of shaft, high viscosity polymer melt is difficult for piling up impact reaction, thereby thoroughly solves the unsettled problem of product quality.
For guaranteeing the heat exchanging process of housing inner chamber, described housing comprises inner housing and shell body, between inner housing and shell body, leaves heating chamber, is respectively equipped with heating agent import, heating agent outlet is connected with heating chamber on shell body.
Larger for guaranteeing high-viscosity melt surface area, allow and react Quick uniform more and carry out, described mouse cage comprises two floral discs that are set in parallel on shaft, is arranged at intervals with some discs between floral disc, leaves the passage that tolerant material passes on floral disc and disc; It is latticed that disc is, and the periphery of floral disc and disc is provided with stiffening ring, between stiffening ring, through some lacing wires, is connected, and increased the rigidity of structure of mouse cage integral body.
Lacing wire can be uniformly distributed on the circumferencial direction of floral disc, can not only strengthen structural strength,, can provide and the more contact-making surface of melt, to form more evaporation surface meanwhile.
For guaranteeing the structural strength between lacing wire, between described lacing wire, through some dowels, be connected.
For guaranteeing two structural strengths between floral disc, the phase of described two floral discs is provided with reinforcement to the inside.
In order to allow mouse cage and melt have more contact, reduce the gap of mouse cage and housing inner chamber bottom, so that polymerisation is more abundant, the axis of described shaft is lower than the axis of housing.
