[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry, and are widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, which has led to in-depth research on the weldability of aluminum alloys. A large amount of waste aluminum is generated in the production process of aluminum alloy die casting plants, aluminum alloy gravity casting plants and other enterprises. In order to improve the recycling rate, the waste aluminum left over from the processing of aluminum profiles is generally recycled. In order to better utilize the recycled aluminum, a smelting furnace is needed to smelt the waste aluminum.
[0003] Existing smelting furnaces typically place crushed scrap aluminum inside, heat and melt it, and then pour out the molten aluminum. However, these furnaces are usually single-layered, and a furnace breakage during use could cause a safety accident. Furthermore, the resulting molten aluminum is of low purity, and residue remains inside the furnace, making cleaning difficult. Therefore, those skilled in the art have provided a scrap parts smelting apparatus to solve the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste parts smelting device, which is equipped with an outer furnace and an inner furnace. The inner furnace is responsible for smelting, while the outer furnace is responsible for protection. This not only effectively reduces safety hazards but also enables multiple filtrations and convenient cleaning of residues.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A waste parts smelting device includes an outer furnace, an inner furnace, and a connecting mechanism. A lifting plate is movably sleeved inside the inner furnace. A connecting cylinder is fixedly connected to the center of the upper surface of the lifting plate. A first circular hole is opened on the upper part of the outer surface of the connecting cylinder. A connecting column is movably sleeved inside the connecting cylinder. A second circular hole is opened on the upper part of the outer surface of the connecting column. A connecting hole is opened on the lower side of the outer surface of the connecting column.
[0007] Guide tubes are fixedly connected to both sides of the outer surface of the inner furnace, and placement blocks are fixedly connected to both sides of the lower end face of the inner furnace. A filter plate is movably sleeved between the two placement blocks. A T-shaped block is fixedly connected to the center of the inner bottom surface of the filter plate. The connecting mechanism includes a hollow block and two bolts. A connecting block is threaded between the two bolts. The upper end face of the connecting block is fixedly connected to the lower end face of the hollow block.
[0008] Furthermore, the lower end of the connecting column passes through the lifting plate and extends to the bottom, and the first and second circular holes are connected.
[0009] Furthermore, heat-conducting plates are fixedly connected to both the front and rear of the outer surface of the inner furnace, and the opposite sides of the two heat-conducting plates are fixedly connected to the front and rear inner walls of the outer furnace, respectively.
[0010] Furthermore, the two guide tubes are fixedly connected to the inner walls of the outer furnace on opposite sides, and the outer surface of the T-shaped block is movably fitted inside the connecting hole.
[0011] Furthermore, a No. 1 flow guide port is provided on both upper sides of the inner wall of the inner furnace, and a No. 2 flow guide port is provided on both sides of the outer surface of the filter plate.
[0012] Furthermore, filter plates are fixedly sleeved on opposite sides inside the two No. 1 flow guide ports, and the connecting mechanism is set on the upper end face of the connecting cylinder.

[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model proposes a waste parts smelting device. A heat-conducting plate transfers the temperature of the outer furnace to the inner furnace. After smelting in the inner furnace, a connecting block is connected to a connecting cylinder by bolts. The hollow block is lifted upward to move the connecting block, which in turn moves the connecting cylinder. The connecting cylinder drives the lifting plate to move, thereby raising the position of the molten aluminum in the inner furnace. Then, it enters the guide pipe through the first guide port. A filter plate is installed on the first guide port. The filter plate has multiple holes to trap large-volume residues in the inner furnace. Then, the molten aluminum in the guide pipe enters the filter plate through the second guide port. The bottom surface of the filter plate has multiple holes for secondary filtration of the molten aluminum. The diameter of the holes on the filter plate is smaller than that on the filter plate, which can retain smaller residues in the filter plate. Only the filter plate needs to be replaced periodically, without the need for cleaning each time.
[0016] 2. The waste parts smelting device proposed in this utility model allows for the following steps: When cleaning the residue on the lifting plate, remove the cover and continue moving the lifting plate upwards. The lifting plate will bring large-volume residue to the furnace opening for easy cleaning. When cleaning the filter plate, screw the bolts into the connecting column, which will also cause the filter plate to rise. Move the filter plate completely outside the furnace, remove the T-shaped blocks on the filter plate from the connecting holes on the connecting column, and connect the T-shaped blocks on the new filter plate to the connecting holes on the connecting column. The filter plate can be reused after cleaning. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6This utility model provides an embodiment of a waste parts smelting device, comprising an outer furnace 2, an inner furnace 13, and a connecting mechanism 4. A discharge port 1 is fixedly connected to the lower front surface of the outer furnace 2. A cover 3 is slidably connected to both the front and rear sides of the upper end of the outer furnace 2. Heat-conducting plates 14 are fixedly connected to both the front and rear sides of the outer surface of the inner furnace 13. The opposite sides of the two heat-conducting plates 14 are respectively fixedly connected to the front and rear inner walls of the outer furnace 2. A first-order guide port 5 is opened on both upper sides of the inner wall of the inner furnace 13. The two first-order guide ports 5 are oriented in opposite directions. A filter plate 12 is fixedly sleeved on the side. A lifting plate 9 is movably sleeved inside the inner furnace 13. A connecting cylinder 11 is fixedly connected to the center of the upper end face of the lifting plate 9. A first round hole 17 is opened on the upper part of the outer surface of the connecting cylinder 11. A connecting column 10 is movably sleeved inside the connecting cylinder 11. A second round hole 18 is opened on the upper part of the outer surface of the connecting column 10. The first round hole 17 and the second round hole 18 are connected. The lower end of the connecting column 10 passes through the lifting plate 9 and extends to the bottom. A connecting hole 16 is opened on the lower side of the outer surface of the connecting column 10.
[0027] Guide pipes 6 are fixedly connected to both sides of the outer surface of the inner furnace 13. The two guide pipes 6 are fixedly connected to the inner walls of the outer furnace 2 on opposite sides. Placement blocks 15 are fixedly connected to both sides of the lower end face of the inner furnace 13. Filter plate 7 is movably sleeved between the two placement blocks 15. Second guide ports 19 are opened on both sides of the outer surface of the filter plate 7. T-shaped block 8 is fixedly connected to the center of the inner bottom surface of the filter plate 7. The outer surface of T-shaped block 8 is movably sleeved inside the connecting hole 16. The connecting mechanism 4 is set on the upper end face of the connecting cylinder 11. The connecting mechanism 4 includes a hollow block 401 and two bolts 403. A connecting block 402 is threaded between the two bolts 403. The upper end face of the connecting block 402 is fixedly connected to the lower end face of the hollow block 401.
[0028] Specifically, the shredded waste parts are placed inside the inner furnace 13. The heat-conducting plate 14 transfers the temperature of the outer furnace 2 to the inner furnace 13, causing the temperature of the inner furnace 13 to rise. The shredded waste parts are then melted inside the inner furnace 13. After melting, the connecting block 402 is connected to the connecting cylinder 11 by bolts 403. The hollow block 401 is then lifted upwards. The movement of the hollow block 401 moves the connecting block 402, which in turn moves the connecting cylinder 11. The movement of the connecting cylinder 11 then moves the lifting plate 9, which moves upwards. The movement causes the molten aluminum in the inner furnace 13 to rise, and then the molten aluminum enters the guide pipe 6 through the first guide port 5. The first guide port 5 is equipped with a filter plate 12, which has multiple holes to trap large-volume residues in the inner furnace 13. The molten aluminum in the guide pipe 6 enters the filter plate 7 through the second guide port 19. The bottom surface of the filter plate 7 has multiple holes for secondary filtration of the molten aluminum. The diameter of the holes on the filter plate 7 is smaller than the diameter of the holes on the filter plate 12, so that smaller residues can be retained in the filter plate 12.
[0029] After filtration is complete, remove the cover 3 and continue to move the lifting plate 9 upward. The lifting plate 9 will bring the large volume of residue to the furnace opening for easy cleaning. When cleaning the filter plate 7, simply screw the bolt 403 into the connecting column 10 so that the connecting column 10 is connected to the connecting block 402. The movement of the connecting column 10 will drive the T-block 8 to move, and the movement of the T-block 8 will also cause the filter plate 7 to rise. Move the filter plate 7 completely outside the furnace, remove the T-block 8 on the filter plate 7 from the connecting hole 16 on the connecting column 10, and connect the T-block 8 on the new filter plate 7 to the connecting hole 16 on the connecting column 10. The filter plate 7 can be reused after cleaning.
[0030] Working principle: The crushed waste parts are placed in the inner furnace 13. The heat conduction plate 14 conducts the temperature of the outer furnace 2 to the inner furnace 13. The waste parts are smelted in the inner furnace 13. After smelting, the connecting block 402 is connected to the connecting cylinder 11 by bolt 403. The hollow block 401 is lifted upward. The hollow block 401 moves and drives the connecting block 402. The connecting block 402 moves and drives the connecting cylinder 11. The connecting cylinder 11 moves and drives the lifting plate 9. The lifting plate 9 moves upward and raises the position of the aluminum liquid in the inner furnace 13. The aluminum liquid enters the guide pipe 6 through the first guide port 5. The first guide port 5 is equipped with a filter plate 12 to block large-volume residues in the inner furnace 13. The aluminum liquid in the guide pipe 6 enters the filter plate 7 through the second guide port 19 for secondary filtration of the aluminum liquid, retaining smaller residues in the filter plate 12.
[0031] Secondly, after filtration is complete, remove the cover 3 and continue to move the lifting plate 9 upward. The lifting plate 9 will bring the large volume of residue to the furnace opening for easy cleaning. When cleaning the filter plate 7, simply screw the bolt 403 into the connecting column 10, so that the filter plate 7 will also be driven to rise. Move the filter plate 7 completely outside the furnace, remove the T-shaped block 8 on the filter plate 7 from the connecting hole 16 on the connecting column 10, and connect the T-shaped block 8 on the new filter plate 7 to the connecting hole 16 on the connecting column 10. The filter plate 7 can be reused after cleaning.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
