Definitions

  • the present invention relates to a channel and a method for guiding and conditioning a glass melt with a floor drain which has a basin in the lower region.
  • streaks occur in the melting tank due to the contact between the tank material and the glass melt.
  • a streak is a contamination in the glass melt.
  • the density of the streaks can be larger or smaller than the glass melt. So far, attempts have been made to remove the streaks by stirring. It has been shown that, in particular, specifically heavier streaks, such as streaks containing ZrO 2 , cannot be substantially eliminated by stirring.
  • the streaks are guided with the glass melt from the melting trough over the feeder channel to the feeder head and are visible in the product.
  • the object of the present invention is to provide a device and a method for reducing the streaks in the glass product.
  • the object is achieved by a device for guiding and conditioning a glass melt, with a gutter with a floor drain which has a basin in the lower region.
  • the glass melt is guided over a channel, with streaks with a higher density settling in the basin.
  • the deposited contamination is removed by at least one floor drain.
  • a preferred embodiment of the invention is a device for guiding and conditioning a glass melt, the basin having a triangular geometry.
  • the pelvis tapers towards the bottom.
  • the heavy streaks sink and separate in the taper.
  • the melt enriched with streaks in the lower area is drawn off through the floor drain if necessary.
  • a further preferred embodiment of the invention is a device for guiding and conditioning a glass melt, the electrodes for thermal mix conditioning in the gutter are arranged asymmetrically. With this measure according to the invention, the formation of thermally formed streaks is reduced.
  • the object of the invention is further achieved by a method for low-streaking production of a glass, the glass melt being guided in the trough with a basin, heavier components settling in the basin and being discontinuously drawn off through a floor drain and the glass melt being fed to the feeder head.
  • the use of a basin for separating heavier constituents in the glass melt in a feeder channel is provided.
  • FIG. 1 a feeder channel in longitudinal section
  • FIG. 2 a feeder channel in cross section
  • FIG. 3 a plan view of a feeder channel.
  • FIG. 1 the basin (3) according to the invention in a feeder channel (1) is shown as an example.
  • the basin (3) has at least one floor drain (2).
  • the glass melt passes through the feeder channel (1), and heavier components of the glass melt can settle in the basin (3).
  • Fig. 2 the geometry of the feeder (1) and the basin (3) is shown.
  • 3 shows the asymmetrical arrangement of the electrodes (4).

Abstract

L'invention concerne une rigole permettant de guider et de conditionner du verre fondu, avec un siphon de sol, qui comporte une cuve dans la zone inférieure. L'invention concerne en outre un procédé permettant de produire un verre avec peu de stries. Le verre fondu est guidé dans la rigole d'alimentation avec la cuve. Les constituants lourds se déposent dans la cuve et sont extraits de manière discontinue par un siphon de sol et le verre fondu est guidé jusqu'à la tête d'alimentation. L'invention concerne pour finir l'utilisation d'une cuve pour séparer les constituants lourds dans le verre fondu dans une rigole d'alimentation.
