Abstract

12,766. Wedge, U. May 29. Charging.-In roasting and other furnaces, especially those of the type in which the material to be treated is caused to travel through the furnace by means of stirring-arms fastened to a vertical rotary shaft, provision is made for feeding the material through apertures at the top of the furnace in such a manner that the escape of hot gases is prevented. Fig. 1 shows the invention applied to a furnace witb superposed muffled chambers a. The material is fed from a storage bed d, which also serves as a drying-floor, on to a delivery bed e communicating with the storage bed d by a passage g, which is constantly filled with material, thus forming a gastight closure. The passage g is formed by mounting upon the shaft b a flange or plate h, so as to leave an annular passage between the inner edge of the bed d and the edge of the flange h. To form a more effective seal, the flange h is provided with a vertical flange i having one or more openings j, as shown in Fig. 4. To stir the ore on the drying-bed, and at the same time to feed it forward gradually, a number of stirring-blades p are mounted un the transverse beam e attached to the shaft b. The blades p are adapted to rise and fall by being mounted on a bar o, Fig. 2, which is secured to a rocking shaft m. One or more inclined rabbles q may be provided, projecting into the passage g and serving to feed the material on to the delivery bed. In order to feed the material from the delivery bed into the working-chamber a, an adjustable blade r, Figs. 1 and 3, guided in a sealed opening t within a box s, and maintained in position by a screw u, is mounted on the flange h. In the modified form of feeding-device shown in Fig. 6, the delivery bed e<1> is formed by an horizontal flange e' secured to the shaft b<1>, and the passage g<1> is formed by extending the inner edge of the storage bed d' sufficiently near to the shaft b<1>. An adjustable blade r<1> serves to regulate the amount of ore fed to the furnace.
