Description

Technical Field

[0001] The present invention relates to the technical field of spreading devices, in particular to a medicament spreading device for conditioning heavy metals in coal gangue. Background Art

[0002] Gangue, derived from ancient soil, is a secondary mineral formed by plant remains mixed into the coal during the coal-forming process and deposited under high temperature and pressure. It contains soil components and, through scientific processing, can be transformed into nutrient-rich artificial soil suitable for plant growth, achieving resource reuse and ecological recycling.

[0003] Gangue, a natural relic from coal formation, contains rich traces of ancient soils, including over 30 elements essential for plant growth, including iron, calcium, potassium, phosphorus, zinc, titanium, and selenium. However, most of these elements exist in fixed states, limiting their direct absorption by plants.

[0004] At the same time, some coal gangue may contain heavy metals such as copper, mercury, lead, and arsenic. Excessive levels of these elements can pose a serious threat to the soil environment. To ensure soil health and safety, heavy metals in coal gangue need to be treated to prevent them from being absorbed by plant roots and thus cut off their entry into the food chain.

[0005] Most existing reagent spreading devices spray the reagent directly on the surface of the coal gangue material, which is unable to pre-treat the coal gangue, resulting in the reagent being unable to fully contact the material accumulated inside, thereby affecting the heavy metal treatment effect and failing to achieve effective treatment of heavy metals. For this reason, we proposed a reagent spreading device for regulating heavy metals in coal gangue. Summary of the Invention
