Shredder dust feeding facilities and reverberatory furnace provided with this feeding facilities

Abstract

The present invention relates to facilities for feeding shredder dusts to a reverberatory furnace in which shredder dusts is fed to a reverberatory furnace for non-ferrous smelting, and in particular, to facilities for feeding shredder dusts to a reverberatory furnace in which a feeding chute that passes to the inside of the reverberatory furnace is fitted to the ceiling of the reverberatory furnace and shredder dusts can be fed from this feeding chute, and which also allows oxygen enriched air to be supplied to the feeding chute and fed to the inside of the reverberatory furnace. Further, the present invention relates to a reverberatory furnace for non-ferrous smelting in which a burner is able to be installed in a wall portion of one end side thereof, and in particular, to a reverberatory furnace for non-ferrous smelting in which a plurality of feeding ports to which are connected the feeding chutes of the shredder dusts feeding facilities are provided at the one end side in the ceiling portion thereof forming a plurality of staggered rows facing the other end side.

What is claimed is:  
     
         1 . Facilities for feeding shredder dusts to a reverberatory furnace in which shredder dusts is fed to a reverberatory furnace for non-ferrous smelting and is burned, wherein a feeding chute that passes to the inside of the reverberatory furnace is fitted to a ceiling of the reverberatory furnace and shredder dusts can be fed from the feeding pipe, and wherein oxygen enriched air can also be supplied to the feeding nozzle and fed to the inside of the reverberatory furnace.  
     
     
         2 . The facilities for feeding shredder dusts according to  claim 1 , wherein the feeding chute is branched partway along its length and the shredder dusts is fed from one end of the branched pipe while the oxygen enriched air is supplied in from the other end of the branched pipe.  
     
     
         3 . The facilities for feeding shredder dusts according to  claim 1  or  2 , wherein an air supply nozzle that has a smaller diameter than the feeding chute is inserted in the other end of the branched feeding chute and the distal end of the air supply nozzle is positioned adjacent to the branched portion of the feeding chute and the oxygen enriched air is supplied in from the air supply nozzle.  
     
     
         4 . A reverberatory furnace for non-ferrous smelting provided with the shredder dusts feeding facilities, wherein a burner is able to be installed in a wall portion of one end side of the reverberatory furnace and a plurality of feeding ports to which are connected the feeding chutes of the shredder dusts feeding facilities are provided at the one end side in a ceiling portion forming a plurality of staggered rows facing the other end side.  
     
     
         5 . The reverberatory furnace according to  claim 4 , wherein in the ceiling portion, the one end side where the feeding ports are provided is raised above the other end side.  
     
     
         6 . The reverberatory furnace according to  claim 4  or  5 , wherein a feed chute of the feed facilities is connected to each one of the plurality of feeding ports and the positions at which shredder dusts is fed to the feeding hoppers are arranged in a single row.
