Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal alloy smelting technology, and in particular to an anti-oxidation stirring device for non-ferrous metal alloy smelting. Background Technology

[0002] Non-ferrous metal alloys, with their high strength, corrosion resistance, and excellent electrical and thermal conductivity, are widely used in core areas of modern industry such as aerospace, electronics, automotive manufacturing, and machining. Their product quality directly affects the performance and stability of end-use equipment. Smelting is a crucial step in the production of non-ferrous metal alloys, requiring heating to melt and homogenize the raw materials to ensure the alloy composition meets standards.

[0003] However, the heating structure of traditional smelting equipment is bottom heating, which results in uneven heating temperature. Furthermore, the stirring structure lacks anti-sticking features, which not only leads to insufficient alloy purity and uneven composition, but also waste due to raw materials sticking to the wall, increases cleaning difficulty, and affects smelting efficiency and product quality. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an anti-oxidation stirring device for non-ferrous metal alloy smelting. It can solve the technical problems of the traditional smelting device in the prior art, which has a bottom heating structure, resulting in uneven heating temperature, and the stirring structure lacking anti-sticking structure. This not only causes insufficient alloy purity and uneven composition, but also waste due to raw materials sticking to the wall, increases cleaning difficulty, and affects smelting efficiency and product quality.

[0005] This utility model embodiment proposes an anti-oxidation stirring device for smelting non-ferrous metal alloys, including: a support frame, a heating component, a filter component, and a U-shaped plate control mechanism; The heating assembly includes an outer shell, an inner shell, a spiral heating wire, a discharge pipe, and a switching valve; The filtration assembly includes a feed pipe, a feeding hopper, and a filter screen; The control mechanism includes a servo motor, a first reduction gear, a second reduction gear, and a stirring assembly; The stirring assembly includes a movable rod, a rotating rod, a first fixed rod, a scraper, a second fixed rod, and a spiral stirring blade.

[0006] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the invention, non-ferrous metal raw materials are fed into the feeding hopper of the filter assembly. After impurities are filtered out by the filter screen, the raw materials enter the inner shell of the heating assembly through the feed pipe. The filter screen can reduce the impact of impurities on the purity of the alloy. Then, the spiral heating wire is activated to heat and melt the raw materials. The double-layer structure of the outer shell and the inner shell, together with the spiral heating wire, can achieve uniform heating and improve melting efficiency. During the melting process, the servo motor of the control mechanism is activated. The servo motor drives the first reduction gear to rotate. After being decelerated by the meshing second reduction gear, it drives the movable rod and rotating rod of the stirring assembly to rotate. The first reduction gear and the second reduction gear can make the stirring more stable and controllable. The rotating rod drives the spiral stirring blade to stir the molten alloy to ensure uniform composition. At the same time, the scraper fixed by the first fixed rod and the second fixed rod rotates against the inner wall of the inner shell to avoid alloy sticking to the wall, which would cause waste and cleaning difficulties.
