Technical Field
[0001] The utility model relates to a heavy metal separation device, in particular to a heavy metal separation device used for recycling domestic garbage slag. Background Art
[0002] In today's society, a variety of municipal waste treatment technologies are available. Using waste-to-energy incineration technology, municipal solid waste is burned at high temperatures, forming slag. The slag volume is approximately 10% to 30% of its original volume. The slag is dark brown, with varying particle sizes and a complex composition. Although the slag undergoes sintering, carbonizing a significant amount of carbohydrate impurities, it still contains a significant amount of pre-existing impurities such as glass, iron sheets, bottle caps, and metals such as iron, copper, gold, and silver.
[0003] The heavy metals in the slag from the incineration of domestic waste are metallic materials themselves and need to be sorted, screened, recycled and converted into corporate profits to save resources. However, if the iron heavy metal substances are not treated and randomly piled or buried, they will seriously pollute the environment after leaching. Some iron heavy metal screening devices have high operating costs and are not conducive to use. Utility Model Content
