[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-4The utility model provides a technical solution: a smelting furnace impurity purification device, including a smelting furnace main body 1 and a molten metal barrel 2, a support plate 3 is provided between the discharge port of the smelting furnace main body 1 and the inlet of the molten metal barrel 2, a guide tube 4 is embedded and installed on the support plate 3, both sides of the guide tube 4 are provided with support rods 7 inserted on the support plate 3, an adjustable pressure plate 8 is provided on the outer side of the support rod 7, a vibrator 11 is installed on the outside of the guide tube 4, and a multi-stage filtering mechanism 5 is provided inside the guide tube 4, and a plurality of guide blades 6 are provided at the inlet of the guide tube 4 along the circumferential direction. When the molten metal flows out from the discharge port of the smelting furnace main body 1, this structure can guide the flow through the guide tube 4. In this process, the guide blades 6 guide the molten metal to be evenly distributed and slow down its flow rate. In order to help the impurities therein be fully exposed to the front of the filtering mechanism, the support rod 7 not only provides a stable support for the guide tube 4, but also the adjustable pressure plate 8 on the outside thereof can be adjusted according to actual needs to adapt to the pressure requirements under different working conditions, ensuring the stable flow of the molten metal. The vibrator 11 can generate vibrations outside the guide tube 4 to help loosen the impurities attached to the multi-stage filtering mechanism 5, prevent the filter holes from being blocked, ensure the filtering effect and extend the service life of the equipment. At the same time, the multi-stage filtering mechanism 5 effectively removes fine non-metallic inclusions and high-density metal compounds in the molten metal through the two layers of filter plates with different pore sizes designed inside it, thereby improving the purification efficiency. Therefore, the device not only improves the impurity purification efficiency, ensures the quality of the metal products, but also reduces the subsequent The problems that may occur during processing are solved, which reduces production costs. At the same time, it also solves the problems of low purification efficiency and unstable product quality caused by simple gravity or basic filtering means in the process of transferring molten metal from the smelting furnace to the molten metal barrel 2 in the prior art, bringing higher economic benefits to the enterprise. The multi-stage filtration mechanism 5 is composed of two layers of ceramic filter plates 51 with different pore sizes, and the ceramic filter plates 51 are embedded in the interior of the guide tube 4 through support rings 52. The support rings 52 are welded and fixed on the inner wall of the guide tube 4 and an annular embedding groove is provided on its inner edge. The pore size of the ceramic filter plate 51 on the upper layer of the multi-stage filtration mechanism 5 is larger than that of the ceramic filter plate 51 on the lower layer, and the pore size on the ceramic filter plate 51 gradually decreases. In this structure, the molten metal first passes through the ceramic filter plate with a larger pore size. The large upper ceramic filter plate 51 initially filters out larger particles of impurities, and then flows into the lower ceramic filter plate 51 with a smaller pore size for finer filtration, effectively removing fine non-metallic inclusions and high-density intermetallic compounds, and the support ring 52 is tightly matched with the ceramic filter plate 51 through the annular interlocking groove set on its inner edge, ensuring the stable installation and efficient operation of the filter plate, while avoiding displacement or damage caused by high temperature or high pressure environment, thereby not only improving the filtration efficiency and purification effect, but also ensuring the continuity and reliability of the filtration process. A through-hole is provided in the middle of the support plate 3, which is consistent with the structure of the guide tube 4, and a rubber ring 12 is bonded to the inner wall of the through-hole in the middle of the support plate 3. This structure allows the support plate 3 to accurately match the shape of the guide tube 4 through the through-hole.The stability of the connection between the support plate 3 and the guide tube 4 is strengthened, and the mechanical stress caused by thermal expansion and contraction is also reduced, thereby improving the stability and safety of the entire device. Both sides of the support plate 3 are provided with movable openings, and the support rod 7 and the adjustable pressure plate 8 are both passed through the movable openings of the support plate 3, and the upper and lower ends of the back side of the adjustable pressure plate 8 are provided with positioning shafts 9. The connection between the positioning shaft 9 and the adjustable pressure plate 8 is connected by welding. The upper and lower ends of the movable opening of the support plate 3 are welded and fixed with positioning sleeves 10, and the positioning sleeve 10 is connected with a locking screw through a threaded structure. The movable opening of this structure support plate 3 can be adjusted laterally with the adjustable pressure plate 8, and the adjustable pressure plate 8 can be adjusted by inserting and moving in the positioning sleeve 10 through the positioning shaft 9 to ensure that the position of the adjustable pressure plate 8 is accurate, and the locking screw on the positioning sleeve 10 can fix the position of the adjustable pressure plate 8 by tightening it to prevent it from being caused by vibration and the like during use. The adjustable pressure plate 8 is displaced, and the adjustable pressure plate 8 is an arc-shaped structure and an elastic pad is bonded and fixed on the inner wall, so that the adjustable pressure plate 8 can better fit the outer wall of the guide tube 4, and the elastic pad bonded and fixed on the inner wall can flexibly press against the outer wall of the support rod 7, which not only enhances the friction between the adjustable pressure plate 8 and the support rod 7, ensuring that the adjustable pressure plate 8 can be firmly fixed after adjusting the position, but also can absorb the vibration and impact generated when the molten metal flows. The surface of the guide blade 6 is provided with a plurality of guide ridges, and the guide blade 6 is evenly distributed in a circular shape at the entrance of the guide tube 4. This structure of the guide blade 6 and the guide ridges on its surface can effectively guide the molten metal to enter the guide tube 4 evenly. The turbulent effect of the guide ridges can promote the floating of tiny bubbles and light impurities inside the molten metal, while reducing the turbulence and impact of the molten metal when entering the guide tube 4, ensuring that the molten metal passes through the guide tube 4 smoothly and orderly.
[0019] Working principle: When using the impurity purification device for a smelting furnace, the molten metal first flows out from the discharge port of the smelting furnace body 1 and enters the interior of the guide tube 4, where it contacts a number of guide blades 6. At this time, the guide blades 6 guide the molten metal to be evenly distributed and slow down its flow rate. The molten metal is then filtered through a multi-stage filter mechanism 5 inside the guide tube 4. The ceramic filter plate 51 on the upper layer of the multi-stage filter mechanism 5 first preliminarily filters out larger particles of impurities, and the ceramic filter plate 51 on the lower layer then performs a finer filtration to remove fine non-metallic inclusions and high-density intermetallic compounds. At the same time, the outside of the guide tube 4 The vibrator 11 generates vibration to help loosen impurities attached to the ceramic filter plate 51 and prevent the filter holes from being blocked. After multi-stage filtration, the molten metal flows into the molten metal barrel 2 through the outlet of the guide tube 4. At the same time, the adjustable pressure plate 8 can be adjusted according to actual needs during this process. When the adjustable pressure plate 8 is adjusted laterally, it is inserted and moved in the positioning sleeve 10 through the positioning shaft 9, and the position of the adjustable pressure plate 8 is fixed by the locking screw on the positioning sleeve 10 until the adjustable pressure plate 8 moves to a suitable position at the through-hole of the support plate 3 to press against the outer wall of the support rod 7 to prevent displacement caused by vibration, thereby completing a series of tasks.
