Air cooling apparatus for vertical extruders |
摘要 |
Air-cooling apparatus for a heat-exchange jacket which surrounds the outside of a vertical extruder barrel. The apparatus comprises a hood which surrounds the jacket and includes a plenum chamber at one side of the jacket, an outlet opening at the opposite side of the jacket and a restricted inlet opening between the jacket and plenum chamber wherein the hood provides a through-passage between the inlet and outlet openings. Means are provided for forcing air into the plenum chamber to create a super-atmospheric pressure therein and provide an air flow through the through-passage. The hood also includes an outlet chamber adjacent the outlet opening which has the same vertical cross-sectional configuration as the plenum chamber to provide a balanced air draft condition on opposite sides of the heat-exchange jacket.
