Revolving melting furnace of multi-stage type

Abstract

Abstract PURPOSE:To keep molten components from solidifying and piling up and discharge them smoothly from each revolving melting chamber by providing a first stage revolving melting chamber provided with a charging port for objects to be melted and an air port into which the combustion air is blown in and a second stage revolving melting chamber provided with an air port into which the combustion air is blown in and arranging both revolving melting chambers so as to have communication between them. CONSTITUTION:A first stage revolving melting chamber 4 has a cylindrical section and at its upper section a charging port 13 for objects to be melted and an air port 2 into which the combustion air is blown in, both port 13 and port 2 being located in the direction of a tangential line to the cylindrical section in order to form a revolving air flows for the objects to be melted in the melting chambers and melt them by combustion. Below this first stage revolving melting chamber 4 an outlet throttling section 11 is provided which is constituted of an inclining face 12 with its inner diameter gradually reduced, and a second stage revolving melting chamber 5 is connected which has a downwardly inclining cylindrical section. Its inlet section 18 communicates with the outlet throttling section 11. Further, to be second stage revolving melting chamber 5 an air port 3 into which the combustion air is blown is provided in the direction of a tangential line to the melting chamber 5. With this multistage arrangement the outlet throttling section 11 receives radiation heat from the second stage revolving melting chamber 5 so that there is almost no solidification of the objects to be melted and they are discharged smoothly.
