[0002] At present, environmental protection and process technology are developing towards high quality and refinement, and are in an important stage of industrial transformation and upgrading. Environmental protection, occupational health and resource utilization are gradually deepening.
[0003] Existing technologies such as Figure 1 As shown: During the electrolytic zinc smelting process, after the "zinc scale stuck" fault occurs at the feed port of the induction furnace, the workshop operator generally lifts and swings the feed port. When the feed port is lifted and swung, gaps are generated, causing smoke leakage, further affecting the on-site operating environment and on-site hygiene.
[0004] Ammonium chloride is added to the electrolytic zinc induction furnace to solve the problem of zinc inclusion in zinc slag, so a large amount of smoke is generated in the furnace. Since the feeding port and the furnace body are movably connected, they can be lifted freely by a crane. However, during the lifting process, smoke will leak out, which can easily affect the on-site operating environment, on-site hygiene, resource utilization and processing costs.
[0005] In view of this, we propose a smoke leakage prevention and treatment structure during the lifting process of the feeding port of the casting induction furnace. Utility Model Content
