APPARATUS FOR ELIMINATING AUTOMATICALLY THE SOOT OF A WATER TANK SMOKE TUBE WITHIN A BOILER IN THE INSIDE UPPER, MIDDLE, AND LOWER LATERAL SMOKE TUBES BY THE ROTATION OF UPPER, MIDDLE, AND LOWER SCREW SHAFTS

摘要

PURPOSE: An apparatus for eliminating automatically the soot of a water tank smoke tube within a boiler is provided to control arbitrarily the feeding speed of combustion gas transferred to upper, middle, and lower screws, thereby improving thermal efficiency to the maximum.;CONSTITUTION: Upper, middle, and lower shafts(21,31,41) pass through both side walls in the inside of upper, middle, and lower lateral smoke tubes(20,30,40). The upper, middle, and lower shafts have upper, middle, and lower removing tools(22,32,42). The upper, middle, and lower screw removing tools have the external diameter smaller than the inside diameter of the smoke tubes up to 2 to 4mm. The upper and lower screw removing tools are formed in the right direction and the middle screw removing tool is formed in the left direction so as for combustion gas to be transferred from a lower inlet(13) to an upper outlet(14) in the same direction. The sprocket of a motor reduction gear shaft and the sprocket of the middle shaft are connected to the chain. 2 gears mounted on the middle shaft are engaged with gears mounted on the upper and lower shafts.;COPYRIGHT KIPO 2010
