Melting Process Having Sheathing That Can Be Pushed Through

Abstract

The invention relates to methods and devices for melting furnaces, conveying paths and conveying means for the melt, the melt product and for any type of discharges from a melting furnace and transportation means for the melt, with an extended service life, which in the case of a complete screen, that is to say in the optimum situation, may also be infinite, and/or with increased purity of the melt. This is achieved by the pushing-through or rotating-through of screens, clinkers, coatings, linings, etc., that is to say solid materials which are situated between the melt or melt product or the discharges and the materials situated behind the same which counteract the pressure of the melt, of the melt product or the discharges, for example walls. Here, new pieces of the screens etc. may be added at one free end, and used or worn pieces of the screens can be removed or withdrawn at another free end.

1 . A method for screens of conveying paths of the melt/melt product and/or melting furnaces and/or transportation means for the melt/melt product and/or discharges from the melting process, in particular for glass melting, characterized in that
 the screen or screens can be pushed and/or rotated through the conveying paths of the melt/melt product and/or melting furnaces and/or transportation means for the melt/melt product and/or discharges from the melting process, at least while the respective region is performing its main function, such that at one free end pieces of the screen can be added and at another free end pieces of the screen can be removed.   
     
     
         2 . The method as claimed in  claim 1 , wherein at least one screen composed of at least one piece of the screen can be at least pushed through and/or rotated through. 
     
     
         3 . The method as claimed in  claim 1 , wherein at least one piece of screen can be at least raised and/or lowered and/or moved into the chamber. 
     
     
         4 . The method as claimed in  claim 1 , wherein at least two pieces of the screen at least partially and at least temporarily overlap. 
     
     
         5 . The method as claimed in  claim 1 , characterized in that at least one piece of the screen can be moved at least back and forth. 
     
     
         6 . A device for screens of conveying paths of the melt/melt product and/or melting furnaces and/or transportation means for the melt/melt product and/or discharges from the melting process, in particular for glass melting, characterized in that
 the screen or screens can be held and/or guided and/or moved through the conveying paths of the melt/melt product and/or melting furnaces and/or transportation means for the melt/melt product and/or discharges from the melting process, at least while the respective region is performing its main function, by means of the guide and/or the retention device and/or movement device, such that pushing-through and/or rotated-through and/or erecting and/or displacement into the chamber can take place, in such a way that at one free end pieces of the screen can be added and at another free end pieces of the screen can be removed.   
     
     
         7 . The device as claimed in  claim 6 , wherein at least one piece of the screen has at least one guide and/or at least one retention device and/or at least one movement device. 
     
     
         8 . The device as claimed in  claim 6 , wherein at least one screen has at least one guide and/or at least one retention device and/or at least one movement device. 
     
     
         9 . The device as claimed in  claim 6 , wherein at least one piece of screen has at least one passage opening. 
     
     
         10 . The method as claimed in  claim 5 , wherein at least one screen is composed of at least one piece of the screen ( 6 . a ).
