PROCEDIMENTO E DISPOSITIVO PER OMOGENEIZZARE UNA MASSA FUSA DI VETRO

摘要

The invention relates to a method and a device for homogenizing a glass melt using at least one stirring means which is respectively arranged in a stirring vessel having an inlet (4) and an outlet (5), the respective stirring means having a plurality of stirrer blades (11, 20, 21) arranged spaced apart from one another along a common stirrer shaft (10). According to the invention, the stirring means and/or the device is configured in such a way that a net conveying effect of the stirring means overall from the inlet to the outlet is substantially imperceptible. The conveying effect of the stirring means overall from the inlet (4) to the outlet (5) is caused by the positioning of the stirring blades (11, 20, 21), by the geometric shape thereof and/or by the angular position of the stirring blades in the circumferential direction of the stirrer shaft (10). According to the invention, the rotational speed of the stirring means can be freely varied at least within certain limits, in order to set a desired degree of homogenization of the glass melt, without this leading to a significant change in the total throughput of the device.
