Heating apparatus for vertically and helically conveying workpiece

Abstract

The invention makes public heating apparatus for vertically and helically conveying workpiece, including the main bracket, on which interconnected heating furnace and cooling furnace are arranged in parallel; The bracket is placed inside the heating furnace, the 1st spiral supporting plate is spiraling on the bracket, and conveyer belt is arranged on the 1st spiral supporting plate along spiral direction; one or multiple gas inlet/inlets are set on the heating furnace body to fill protective gas into furnace; The 2nd spiral supporting plate is spiraling vertically inside the mentioned cooling furnace; the direction of the mentioned conveyer belt inside the cooling furnace is uniform to that of the 2nd spiral supporting plate; drive mechanism for conveyer belt is installed on the mentioned main bracket. One or multiple gas inlet/inlets are set on the cooling furnace body to fill protective gas into furnace; the conveyer belt runs through the mentioned heating furnace and cooling furnace and forms one loop via drive mechanism. The protective atmosphere spiral conveying heating furnace and spiral conveying cooling device is energy-saving and space saving with high efficiency.
