Heating apparatus for vertically and helically conveying workpiece

A vertical and helical conveyer system for conveying a work piece, comprising:

• a heating furnace having a first opening and a second opening;
• a first spiral supporting plate installed in the heating furnace;
• a plurality of first supporting bars vertically disposed inside of the first spiral supporting plate and connected to the first spiral supporting plate;
• a first upper rotating shaft connected to top ends of the first supporting bars and penetrating a top plate of the heating furnace, the first upper rotating shaft installed to the top plate of the heating furnace via a bearing, wherein a part of the first upper rotating shaft is disposed outside of the top plate of the heating furnace;
• a first lower rotating shaft connected to bottom ends of the first supporting bars and penetrating a bottom plate of the heating furnace, the first lower rotating shaft installed on a base via a bearing;
• a cooling furnace having a third opening and a fourth opening;
• a second spiral supporting plate installed in the cooling furnace;
• a plurality of second supporting bars vertically disposed inside of the second spiral supporting plate and connected to the second spiral supporting plate;
• a second upper rotating shaft connected to top ends of the second supporting bars and penetrating a top plate of the cooling furnace, the second upper rotating shaft installed to the top plate of the cooling furnace via a bearing, wherein a part of the second upper rotating shaft is disposed outside of the top plate of the cooling furnace;
• a second lower rotating shaft connected to bottom ends of the second supporting bars and penetrating a bottom plate of the cooling furnace, the second lower rotating shaft installed on the base via a bearing;
• a conveyer belt running into the heating furnace through the first opening, arranged on the first spiral supporting plate, running out of the heating furnace through the second opening, running into the cooling furnace through the third opening, arranged on the second spiral supporting plate, and running out of the cooling furnace through the fourth opening, the conveyer belt forming a closed loop;
• a first motor driving the first lower rotating shaft and the second lower rotating shaft;
• a plurality of guiding rollers guiding the conveyer belt;
• and
• a second motor driving the guiding rollers.
