This drain structure includes a drain pipe with unobstructed drainage. A detachable scale settling device, comprising a magnesium rod, is installed within the drain pipe. This magnesium rod reacts with carbonate ions in the boiler, forming magnesium carbonate crystals on its surface. During operation, the magnesium rod is installed within the drain pipe, effectively sealing the drain channel. The carbonate ions in the hot water of the boiler preferentially react with the magnesium rod, precipitating magnesium carbonate crystals. This prevents calcium ions from reacting with carbonate ions, reducing the amount of calcium carbonate deposited on the boiler's inner wall and extending the cleaning machine's lifespan. Subsequently, the magnesium rod can be removed from the drain channel for cleaning. Simultaneously, when the scale settling device is removed, wastewater from the boiler can be discharged through the drain channel, effectively reducing scale buildup on the boiler's inner wall and extending the cleaning machine's lifespan.
