Description

Technical Field

[0001] The utility model relates to the technical field of alloy production casting, in particular to a purification structure for exhausting smoke in ferrochrome alloy production casting. Background Art

[0002] Due to the high temperature of alloy casting smoke, the air pressure at the smoke source increases, causing the high-temperature smoke to quickly diffuse to the low-temperature and low-pressure area, causing uneven air pressure distribution, and the presence of unstable interfering airflow around, resulting in extremely fast diffusion of smoke, and the diffusion law is even less obvious, causing serious spillover of smoke in the local sealed space. The local sealed smoke hoods currently used by enterprises cannot effectively capture high-temperature smoke. Alloy casting smoke has the characteristics of large volume, high temperature, high smoke concentration, and small particle size, resulting in a harsh on-site working environment, which is prone to respiratory diseases, lung cancer, silicosis and other occupational diseases. At the same time, it also has a huge impact on the surrounding environment. For example, dust will reduce visibility, affect plant growth and traffic order, and the emission of harmful gases will cause photochemical pollution, acid rain and other environmental pollution, which will damage human health.

[0003] There is smoke pollution in the production area, and employees do not have a good working environment during production activities. Therefore, it is necessary to propose a purification structure for exhausting smoke in the casting of ferrochrome alloy production. Utility Model Content

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up movable smoke hoods, the smoke generated during the casting process of ferrochrome alloy production is centrally treated to avoid smoke and dust pollution in the production area and ensure that employees have a better working environment during production activities.
