Description

Technical Field

[0001] The utility model relates to the field of recovery of metallic iron from electrolytic aluminum, in particular to a metallic iron recovery device for crushing electrolytic aluminum slag. Background Art

[0002] Electrolytic aluminum is a common process for producing high-purity aluminum and is also one of the main methods for producing aluminum in industry. The process of electrolytic aluminum is to dissolve aluminum oxide (Al2O3) in molten salt and reduce the aluminum oxide to aluminum metal by electrolysis. The slag contains a lot of metallic iron, which has a certain value and can be recycled to avoid waste.

[0003] After searching, a solid waste recycling and processing device with announcement number CN212263506U includes a bottom plate, a coarse crushing mechanism is installed on the upper end of the bottom plate through a support frame, an opening is arranged on the upper end of the coarse crushing mechanism, and the lower end of the coarse crushing mechanism is open-shaped. A reduction motor is also fixedly installed on the support frame, and the reduction motor is horizontally arranged. The output shaft of the reduction motor is rotatably connected with a shell, and the upper end of the shell is open-shaped, and the shell is connected with the coarse crushing mechanism. When the device is used, the coarse crushing mechanism is used to preliminarily crush the solid waste, and the crushed solid waste will fall into the shell, and the metal iron in the solid waste will be attracted by the electromagnet, and the metal iron will be adsorbed on the side wall of the shell. After completion, the shell is turned over by the reduction motor, and ordinary solid waste falls first. After the electromagnet is turned off, the metal iron falls, so as to realize the recycling of iron products.

[0004] Based on the above patent, solid waste is initially crushed by a coarse crushing mechanism, and the crushed solid waste will fall into the shell. The metal iron in the solid waste is attracted by the electromagnet and adsorbed on the side wall of the shell. After completion, the shell is turned over by the reduction motor. At this time, ordinary solid waste falls first. After the electromagnet is turned off, the metal iron falls, and the iron products are recycled. However, the coarse crushing mechanism alone cannot completely crush the slag, and there is still metal iron in the large pieces of slag, which will cause a certain amount of resource waste.
