Technical Field
[0001] This utility model relates to the field of circulating pipeline cleaning technology, and in particular to a backwashing and anti-sludge device for circulating pipelines in slag water treatment. Background Technology
[0002] Slag water treatment circulation pipelines are closed-loop pipeline systems used in the industrial field to collect, transport, and treat wastewater generated after the cooling of high-temperature slag. Their main function is to recycle slag water containing high concentrations of solid particles and pollutants through physical filtration, sedimentation, cooling, and water purification, achieving efficient water resource reuse and reducing industrial wastewater discharge. Simultaneously, the circulation pipelines avoid thermal and environmental pollution caused by direct slag discharge and recover some waste heat resources, reducing energy consumption. This system plays a crucial role in ensuring continuous industrial production, reducing operating costs, and promoting green and sustainable development.

Traditional anti-sludge devices often use screens or filters for cleaning, which can easily become clogged. This requires frequent manual cleaning, which is inefficient and increases maintenance costs. Furthermore, it is difficult to completely remove fine particles, leaving impurities behind, which affects the long-term stable operation of the circulation pipeline and shortens the service life of the device.
