Description

Technical Field

[0001] The utility model belongs to the technical field of solid waste reduction treatment, and specifically refers to a solid waste reduction and recycling treatment device for mine environmental management. Background Art

[0002] Solid waste reduction refers to reducing the amount of solid waste generated or its harmfulness, including two aspects: reducing the quantity and reducing the harmful nature of solid waste to the environment. With the rapid growth of mineral resource consumption, the amount of solid waste generated and stored in mines has increased year by year. Therefore, in order to achieve environmental governance while developing, it is necessary to reduce and recycle solid waste in mines.

[0003] Existing solid waste reduction and recycling treatment devices used for mine environmental governance, such as the solid waste reduction and recycling treatment device disclosed in application number CN202310123771.9, include a solid waste crushing component, a metal ion exchange component and a solidification component arranged on the bottom plate, which can crush, extract heavy metals and solidify mine solid waste, thereby improving the reduction treatment effect of mine solid waste.

[0004] However, in the actual recycling of mine solid waste, wet refining is adopted, the types of metals recovered are relatively small, and the treatment method is single, which can mainly recycle uranium, nickel, aluminum, etc., and because mine solid waste also contains other types of metals, such as iron, nickel, cobalt, etc., the metals recovered by the existing recycling and processing devices are not comprehensive enough, resulting in unnecessary waste. In addition, the recycling device in the prior art adopts a horizontal feeding and crushing method, and the solid waste is easy to leak from one side after being crushed, which makes it difficult to ensure the crushing effect, which not only reduces the subsequent recycling effect, but also easily causes damage to the equipment. For this reason, we propose a solid waste reduction and recycling treatment device for mine environmental governance to solve the above problems. Utility Model Content
