Furnace shell outer wall does not have the region of furnace shell horizontal position welding seam to be welded with horizontal cooling tube, is vertically bent to form some cooling water channels, and the port that enters, returns of each cooling water channel arranges respectively water inlet and water return outlet;
Closure when cooling tube is met furnace shell longitudinal seam or furnace shell horizontal position welding seam, is communicated with the closed cooling tube of furnace shell longitudinal seam or furnace shell horizontal position welding seam opposite side by jumper pipe.
Furnace shell outer wall ring week is welded with horizontal bar plate, is welded with vertical gusset perpendicular to horizontal bar plate, and cooling tube is horizontally through vertical gusset.
Cooling tube is semi-circular tube or channel-section steel, and thickness of pipe wall is the 1/4-1/3 of furnace shell thickness.
The water inlet of each cooling water channel and water return outlet are provided with water temperature and detect thermal resistance.
The eminence of water return outlet is provided with safety valve.
The utlity model has following advantage:
Water route of the present utility model adopts semi-circular tube or channel cross-section structure, be welded on furnace shell outer wall, be divided into some water routes by film-cooled heat, simple in structure, cost is low, environmental friendliness, water route adopts jumper pipe to avoid the vertical and horizontal weld seam of furnace shell, cooling tube or channel-section steel wall thickness are much smaller than furnace shell wall thickness, and all water routes weld seam is all positioned at furnace shell outer wall, and structural safety is reliable and maintain easily; In addition, the port that enters, returns of Mei road cooling water has water temperature to detect thermal resistance, and backwater end eminence is provided with safety air release valve, further improves cooling reliability; The cooling structure principle of this device also can be used for various corundum stoves, electric magnesite-smelting furnace etc.
