This invention relates to the field of
platinum feed channels, specifically to a variable cross-section homogenization and purification device for
platinum feed channels used in glass
float glass production. The device includes a feed channel body composed of a contraction section, a homogenization section, and a flaring section. The contraction section is located on one side of the feed channel body at the inlet end. The contraction section has a funnel-shaped structure, with the larger opening end located at the feed end of the feed channel body. The
diameter ratio of the two openings of the contraction section is 4:3, and the length ratio of the contraction section to the
diameter of the smaller opening end is 3.5:3. The homogenization section has a cylindrical structure, with one end connected to the smaller opening end of the contraction section. The flaring section is located at the end of the homogenization section furthest from the contraction section. The flaring section also has a funnel-shaped structure, with the smaller opening end connected to the end of the homogenization section. This invention can suppress glass melt
backflow, simplify the process flow, reduce production
energy consumption, improve homogenization efficiency, and reduce the defect rate.
