Description

TECHNICAL FIELD

[0001] The utility model relates to pyrite technical field, concretely is a kind of pyrite slag desulfurization treatment device. BACKGROUND

[0002] Pyrite is a common sulfur-containing mineral, widely used in sulfuric acid production, metallurgy and chemical industry. However, in the process of mining, beneficiation and smelting of pyrite, a large amount of slag will be produced. These slags usually contain unreacted sulfides, heavy metals and other harmful substances, which will cause serious pollution to the environment if discharged or stacked directly without treatment. Sulfides are easily oxidized to form sulfur dioxide in the natural environment, which in turn forms acid rain, causing damage to soil, water and atmosphere. In addition, heavy metal elements such as lead, cadmium and arsenic in the slag may enter the groundwater system through rainwater erosion, posing a threat to the ecosystem and human health.

[0003] Pyrite slag contains rich iron, which can be used as iron-containing raw material for ironmaking. However, pyrite slag contains unremoved sulfur elements. The existing technology is to crush and grind pyrite slag, then extract the internal iron powder raw material to realize the raw material for ironmaking, and then realize the sulfur collection and desulfurization treatment of pyrite slag after extracting iron powder. There is a lack of a convenient and easy-to-use iron extraction and desulfurization pyrite slag resource utilization device, which is not conducive to the reuse of effective components in pyrite slag. The existing authorized patent "A pyrite slag desulfurization treatment device" with patent number CN202220352445.6 realizes the large-scale swinging action of the bottom of the extraction iron powder long swing arm assembly around the swing arm fixing shaft as the center through the cooperation of multiple structures. The two sides of the bottom of the extraction iron powder long swing arm assembly are provided with extraction iron powder magnetic rod assemblies. The swinging of multiple extraction iron powder magnetic rod assemblies in the sulfur collection and desulfurization pool assembly is driven by multiple extraction iron powder long swing arm assemblies. The iron powder in the ground pyrite slag is magnetically adsorbed by the E-shaped extraction iron powder magnetic rod on the extraction iron powder magnetic rod assembly.

[0004] The extraction iron powder magnetic rod assembly in the above-mentioned utility model has a small area itself, and there is a certain distance between adjacent extraction iron powder magnetic rod assemblies, which is difficult to fully contact with the pyrite slag in the sulfur collection and desulfurization pool assembly, and thus it is difficult to better adsorb the iron powder in the pyrite slag.
