Heating tube: whole body of heater is furnished with and is no less than 10 heating tubes.Every heating tube outside is with stainless steel tube, the end sealing of steel pipe, other end opening.One end of the outside stainless steel tube opening of heating tube is welded with circular clasp, and the external diameter of circular clasp is greater than the aperture of insulation furnace shell inwall perforate.The inner lining of steel pipe ceramic insulating tube.Described heating tube is inner for being wound with the ceramic rod of resistance wire, and the positive pole of resistance wire and negative pole are drawn from an end of the stainless steel tube opening of heating tube outside.Described heating tube inside also can be Elema, and the positive pole of Elema and negative pole are drawn from an end of the stainless steel tube opening of heating tube outside.
One end of heating tube end welded seal is inserted in the side-wall hole place of combustion chamber, and the other end of heating tube is shelved on the tapping of insulation furnace shell inwall, and the circular clasp on the heating tube is positioned at the outside of insulation furnace shell inwall.
The bottom feed bin: the bottom feed bin is positioned at bottom of furnace body.Feed bin inside, bottom is made by stainless steel, and outside with the general steel plate making, central filling aluminosilicate fiber cotton is as insulation material, and the feed bin bottom is provided with discharging opening.
Owing to adopt the mode of inner heating external insulation, so the furnace diameter of heating furnace can design very greatly and not influence the actual efficiency of heating surface, and device energy conservation is efficient, is applicable to the industrialization production of superfine powder.
