[0002] Iron and steel, often called ferrous metals, are categorized into pig iron, wrought iron, and steel. Due to differences in production processes, the sources and properties of wastewater vary. These wastewater can be categorized as ironmaking wastewater, steelmaking wastewater, and rolling mill wastewater. Iron and steel wastewater is typically treated using filtration and purification equipment for recycling.

[0003] Existing equipment, such as CN 216584529 U, describes a pretreatment and softening device for reused cold-rolling wastewater. This device relates to the field of environmental protection equipment and includes a box-shaped pretreatment tank with openings at the top, bottom, and sides. The bottom of the tank is sealed with a base, a support frame is mounted on the top of the base, and a motor is mounted on the side of the tank. The motor's output shaft is located within the tank and is equipped with an agitator. The base extends toward the side opening of the tank and is provided with a mesh-shaped filter screen. A filter box is sealedly connected to the bottom opening of the side of the tank, sealingly covering the upper portion of the filter screen. A valve is installed at the connection between the filter box and the pretreatment tank. This pretreatment and softening device for reused cold-rolling wastewater can efficiently and quickly filter out suspended solids after the dosing reaction, thereby improving the pretreatment efficiency of the cold-rolling wastewater.

[0004] In order to solve the problem that the waste materials and impurities pre-filtered by the existing equipment are difficult to clean, the filter screen in the existing technology is connected to the filter box and the base by welding, which makes it inconvenient for the staff to handle the filtered impurities and maintain the filter screen. The impurities adhere to the surface of the filter screen for a long time, which will affect the efficiency of the equipment. Improvements are needed. Utility Model Content
