A kind of scrap aluminum recovery slag removal device

Abstract

The invention relates to the technical field of metal smelting and recovery, in particular to a waste aluminum recovery and slag removal device, which includes a stirring roller furnace, a hopper, a dust scraping shovel, a driving wheel, a driven wheel, a runner, a hydraulic support, a multi-stage filter and Conveying device, the furnace wall of the stirring roller furnace is equipped with staggered electromagnetic stirring devices and thermocouples for temperature measurement; the retractable dust scraping shovel is located in the stirring roller furnace, and the interior of the dust scraping shovel adopts a hollow structure, and the bottom adopts a porous structure ; The hopper is located directly above the upper surface of the scraping shovel at the mouth of the stirring roller furnace; the main and driven shafts are located under the two sides of the stirring roller furnace, a hydraulic support is installed directly below the rear end pillar of the stirring roller furnace, and the furnace mouth of the stirring roller furnace is directly below A crusher and a multi-stage filter are installed, and a conveying device is arranged under the multi-stage filter; the invention can improve the operation environment and high degree of automation in the process of recycling and slag removal of waste aluminum, and also improve the removal rate of aluminum ash.

Description

technical field [0001] The invention relates to the technical field of metal smelting and recycling, in particular to a waste aluminum recycling and deslagging device. Background technique [0002] Aluminum processing, especially aluminum alloy manufacturing, in order to obtain high-quality, high-purity aluminum ingots or aluminum alloys, various solvents, refining agents, etc. are generally added during the smelting process. After these solid solvents and refining agents are melted, they will melt with them. When the impurities in the melt react, a certain amount of scum, commonly known as aluminum ash, will be formed on the upper surface of the melt. According to the European Hazardous Waste Catalogue, aluminum ash is a toxic and hazardous waste. Direct stockpiling of aluminum ash not only takes up a lot of arable land, but also its salt will slowly accumulate in the soil, resulting in salinization and disrupting the normal physiological activities of the surrounding plant...

Problems solved by technology

[0003] At present, the typical methods for recovering metal aluminum from aluminum ash include frying ash recovery method, tilting rotary kiln method and pressing recovery method, but some of these methods produce a large amount of harmful gas, pollute the environment, and some are easy to operate, but The recovery rate is low and the cost is high. Some have a good operating environment and a high degree of automation, but the recovery rate is low
