This can prevent the accumulation of iron slag from affecting the quality of galvanizing, reduce the viscosity of the flux, improve its fluidity, and cooperate with the magnetic adsorption filter screen to use magnetic force to adsorb iron slag and ferromagnetic impurities, and can intercept finer iron slag particles inside the fluxing bath. When the cleaning scraper scrapes the iron slag in the fluxing bath to the designated area, it is connected to the lifting ring through the operation of the electric winch, driving the cleaning scraper to move upward in cooperation with the slider and the slide rail, enabling automatic salvage, improving the salvage efficiency, optimizing the iron slag cleaning process, thereby improving the galvanizing quality and production efficiency. After the iron slag salvage is completed, it is necessary to manually clean the dirt and iron slag impurities inside the scraper and the filter screen to ensure its normal operation in the follow-up. The motor and the screw are protected by the protective cover and the protective tube, which can prevent the splashing liquid in the fluxing bath and avoid affecting its normal operation due to the accumulation of liquid or dust. When the fluxing liquid reaches the usage standard and becomes wastewater, the drain valve of the fluxing bath is opened, and in cooperation with the operation of the first water pump, it is convenient to pump the wastewater inside to the storage water tank. The spiral rod is rotated by the operation of the drive motor to uniformly stir, and zinc hydroxide and ammonia water are put in through the feeding port to adjust the pH value to 3.0 - 5.5, enabling the metal ions in the wastewater to form precipitates; 2. The hot-dip galvanized workpiece heating device facilitates pumping the wastewater that has been neutralized and precipitated inside the storage water tank to the inside of the filter tank through the operation of the second water pump. The filter tube and activated carbon can adsorb pollutants such as surfactants and oils in the wastewater to ensure that the wastewater meets the discharge standard or the reuse requirement. The normal operation of the filter tank is judged by the change of the pressure gauge. Through the reasonable arrangement of the first electric heating tubes around the fluxing bath and the second electric heating tubes at the bottom, it helps to evenly increase the temperature of the fluxing liquid, can avoid local overheating or overcooling, reduce the damage of thermal stress to the fluxing bath, and quickly heat the fluxing liquid to the process temperature, which can reduce the waiting time and improve the overall efficiency of the production line.
