[0002] In the production of blast furnace pump stations, water needs to be replenished daily due to water evaporation and equipment leakage. The replenishment volume is about 10 m³ / h. However, due to the long-term operation of the water source pipeline, some impurities are present, causing the replenishment water to enter the open-loop clean water tank of the blast furnace pump station and then enter the equipment, resulting in scaling, blockage and other phenomena. Therefore, the water tank needs to be cleaned regularly, which consumes a lot of manpower and resources.

[0003] Traditional filtration devices have poor filtration efficiency, and impurities are difficult to remove from the equipment, leading to accumulation and affecting water replenishment in the blast furnace pump station. Therefore, it is necessary to provide a convenient filtration device for purifying circulating water in blast furnace pump stations. Utility Model Content
