Description

Technical Field

[0001] This utility model relates to the technical field of recycled aluminum smelting, specifically to a furnace for smelting recycled aluminum ingots from waste aluminum. Background Technology

[0002] As is well known, aluminum is a highly corrosion-resistant, lightweight, and hard metallic material. In modern industry, aluminum is gradually replacing steel in the production and manufacturing of industrial equipment. Aluminum can be recycled and repeatedly cast without changing its physical properties. Using recycled aluminum not only improves the metal recycling rate but also reduces energy and water consumption by 95% compared to mining bauxite and electrolytically extracting pure aluminum, achieving significant energy and resource savings. Using recycled aluminum as an organic supplement to new aluminum can both meet the ever-increasing demand for aluminum in economic production and alleviate the over-exploitation of mineral resources.

[0003] When recycling aluminum, it is necessary to smelt it. Existing smelting furnaces do not have material crushing equipment. When smelting scrap aluminum, the materials are of different shapes and sizes, which makes it inconvenient to feed and smelt them, thus affecting the smelting efficiency. Therefore, a scrap aluminum recycling furnace is needed to improve the above problems. Utility Model Content

[0017] Scrap aluminum is added into the crushing box through the first feed hole. The first motor is started, which powers the stirring shaft to rotate, thereby causing multiple stirring rods and crushing blades to rotate. The material is crushed through the combined action of the stirring rods and crushing blades. After crushing, the material is allowed to enter the conveying box through the valve on the feed pipe by opening the valve.

Four support plates 3 are symmetrically fixedly mounted on the mounting plate 2. The four support plates 3 are connected through a crushing box 4. The crushing box 4 has a first feed hole, through which scrap aluminum is added. The conveyor box 9 is welded to the crushing box 4. A first motor 5 is fixedly mounted on the crushing box 4. A stirring shaft 6 is fixedly mounted on the output end of the first motor 5. Multiple stirring rods 7 and multiple crushing blades 8 are fixedly mounted on the stirring shaft 6. When the first motor 5 is started, it provides power to drive the stirring shaft 6 to rotate, thereby causing the multiple stirring rods 7 and multiple crushing blades 8 to rotate. Through the cooperation of the multiple stirring rods 7 and multiple crushing blades 8, the material is crushed. In the crushing operation, a limit plate 14 is fixedly installed on the mounting plate 2, and the limit plate 14 is fixedly connected to the conveyor box 9.

The second motor 11 is started, and the second motor 11 provides power to drive the conveying auger 12 to rotate, and the conveying auger 12 is used to convey the material.

[0028] Please see Figure 1-4A secondary crushing mechanism is provided on the smelting furnace body 1. The secondary crushing mechanism includes two crushing rollers 17. An installation box 15 is fixedly installed on the smelting furnace body 1. The smelting furnace body 1 and the installation box 15 are connected through a second feed hole.

When the third motor 16 is started, it provides power to drive one of the crushing rollers 17 to rotate, which in turn causes the corresponding gear 18 to rotate. Through the meshing of the two gears 18, the two gears 18 drive the two crushing rollers 17 to rotate in opposite directions. Thus, the large pieces of material are crushed again by the compression of the material by the two crushing rollers 17, and then enter the smelting furnace body 1, thereby accelerating the melting speed of waste aluminum and improving the smelting efficiency.

The first motor 5 is started, which powers the stirring shaft 6 to rotate, thereby causing multiple stirring rods 7 and multiple crushing blades 8 to rotate. The material is crushed through the cooperation of the multiple stirring rods 7 and multiple crushing blades 8. After crushing, the valve on the feed pipe is opened, allowing the material to enter the conveying box 9 through the feed pipe. The second motor 11 is started, which powers the conveying auger 12 to rotate, and then... The conveying auger 12 transports the material through the conveying pipe 13 to the installation box 15. The third motor 16 is started, which provides power to drive one of the crushing rollers 17 to rotate, thereby causing the corresponding gear 18 to rotate. Through the meshing of the two gears 18, the two gears 18 drive the two crushing rollers 17 to rotate in opposite directions.
