Abstract:
1. An apparatus for manufacturing a polymer resin, comprising: a polymerization vessel including a main body, and a protruding part which protrudes downwardly from a bottom face of the main body and a lower part of which is composed of a bottom cover; an agitation apparatus including a driving part installed above the main body, a rotatable agitation axis connected to the driving part and extending from the driving part into the protruding part, and a blade provided on a side face of the agitation axis; a bearing part provided on the bottom cover of the protruding part so as to cover the side face of the agitation axis without coming into contact therewith and so as to form a gap between the bearing part and the side face of the agitation axis and between the bearing part and a bottom face of the agitation axis; a solution-retrieving port provided in the main body; a protection part covering the side face of the agitation axis without coming into contact therewith and forming a first flow path between the protection part and the side face of the agitation axis within the protruding part; a first cooling means provided within the main body; a circulating cooling means including a circulating inlet nozzle provided on a side face of the protruding part so as to be opposite to the protection part, a circulation pipeline leading from the main body to the circulating inlet nozzle, and a second cooling means and a circulating pump coupled with the circulation pipeline at a point midway therethrough; a third cooling means provided so as to cover an outer wall of the polymerization vessel; a raw material-injecting nozzle coupled with the protruding part; and a flow path-constituting part provided between the bearing part and the protection part so as to cover the side face of the agitation axis and so as to fix the bearing part and the protection part, the flow path-constituting part forming a second flow path between the side face of the agitation axis and the flow path-constituting part and a third flow path for coupling the second flow path with the raw material-injecting nozzle, wherein the first to third flow paths constitute a continuous flow path, an uppermost end of the first flow path is opened to the inside of the protruding part, and the gap, part of the first flow path other than the uppermost end, the second flow path and the third flow path are isolated from the inside of the protruding part.
