Abstract

The invention discloses a polymerization glue solution film formation distributing device, belongs to a chemical industry device and in particular belongs to a device for forming glue solution as film state because of great viscosity of the polymerization glue solution. The polymerization glue solution film formation distributing device disclosed by the invention comprises a disc-shaped distributor roller fixed on a rotation shaft, wherein a circular plate boss is mounted at the upper part of the distributor roller; the disc-shaped distributor roller is characterized in that 6-12 rectangle scrapping plates in a circular array arrangement are fixedly mounted at the periphery of the disc-shaped distributor roller. By additionally mounting the scrapping plates on the normal distributor with the upper boss, when the rotation shaft rotates at a high speed, a centrifugal force is generated and simultaneously a downward pushing force is generated by the scrapping plates for the glue solution, so that the polymerization glue solution continuously and uniformly forms very thin films and flows along the container wall under the combined action of the centrifugal force and the downward pushing force, thus mass transfer and heat transfer are facilitated. Compared with the normal distributor, the effect of removing the solvent of the polymerization glue solution film formation distributing device disclosed by the invention is improved by several times.

Description

technical field [0001] The invention belongs to chemical industrial equipment, in particular to equipment for forming the glue into a thin film state due to the high viscosity of the polymerized glue. Background technique [0002] For solution polymerization, the removal of solvent from the polymer glue is an important process. The solvent removal process is generally in a vacuum state to form a thin film of the polymer glue on the surface of the hot wall to remove the solvent. In the solvent removal process of the polymer glue, how to make the viscous polymer glue form a thin film is a key link, and the film-forming effect directly affects the solvent removal effect. For many polymers, it is difficult to form a continuous and uniform film because the polymer glue is very viscous. At present, the commonly used method is to install a glue distributor with an upper boss on the high-speed rotating shaft, and feed the glue tangentially to the distributor. Under the action of th...
