Title:
METHOD FOR REMOVING VOLATILE CONTENT IN VENT APPARATUS
Document Type and Number:
Japanese Patent JP3700203
Kind Code:
B2
Abstract:
PURPOSE: To efficiently perform removal of volatile content by using a molding material used for molding as a filtering medium for a filter in a vacuum vent passage of a vent apparatus.
CONSTITUTION: In a vent apparatus wherein a vent hole 3 is provided in a heating cylinder 1 in which a screw is built and a vacuum vent passage 4 provided with a vacuum pump is connected to the vent hole 3 and the volatile content in the molding material is exhausted out of the heating cylinder by decreasing the pressure in the vent hole by means of the vacuum pump, for removal of the volatile content, a filter 7 which is filled with a particulate filtering medium 8 is provided in the vacuum vent passage. The molding material used for molding is used as the filtering medium 8.
