A disassembly and assembly mechanism for collecting dust is provided inside 111. When the gasifier needs to be cleaned, the output end of the starting motor 102 can drive the first pulley 103 to rotate. When the first pulley 103 rotates, the second pulley 105 can be driven to rotate through the transmission belt 104. When the second pulley 105 rotates, the first rotating rod 106 can be driven to rotate. When the first rotating rod 106 rotates, it can rotate through the bearing inside the furnace body 1. When the first rotating rod 106 rotates, it can drive the first bevel gear 107 to rotate. When the first bevel gear 107 rotates, it can drive the second bevel gear 108 to mesh and rotate.
