Description

Technical Field

[0001] This invention relates to the field of metallurgical and mining equipment technology, specifically to a dust control device and method for metallurgical mining. Background Technology

[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and processing them into metallic materials with specific properties using various methods. Metallurgy has a long history, from the Stone Age to the Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development is intertwined with the history of metallurgy. During metallurgical mining operations, a large amount of dust is generated. To prevent this dust from directly entering the atmosphere and polluting the environment, metallurgical mines need to employ dust control devices to collect and manage the dust.

[0003] Patent announcement number CN211799722U discloses a dust control device for metallurgical mining, including a base plate, a dust collection unit, and an extraction structure. The base plate has a discharge port on its bottom side with a conveying hopper, and the inlet on the upper side of the conveying hopper is connected to the inner cavity of a dust treatment cylinder. A second dust collection box is located on the bottom side of the conveying hopper, and its discharge port is also connected to the inner cavity of the second dust collection box. A dust treatment cylinder is located on the upper side of the base plate, with a fixing plate fixed to the outside of the dust treatment cylinder. Two fixing rods are fixed to the upper end of the inner side of the dust treatment cylinder, and the two fixing rods are perpendicular to each other.

[0036] This invention provides a dust control method for metallurgical mining to address another technical problem, comprising the following steps: S1. Adjustment of the vacuum head By activating cylinder 23, the first support plate 21 slides up and down on the surface of support rod 22, thereby adjusting the height of the suction head 31. Then, by activating motor 202, the motor 202 drives the second spur gear 29 and the first spur gear 28 to rotate synchronously, and drives the rotating rod 27 and the rotating disk 24 to rotate synchronously, thereby achieving the purpose of adjusting the angle of suction head 31 and enabling the adsorption of dust at different angles and heights.

[0038] S3, Wet dust collection As the dust passes through two filter plates 43, impurities inside the dust are adsorbed.

At this time, the dust passes through two filter plates. 43. Under the action of the filter plate 43, impurities inside the dust can be adsorbed. At the same time, by starting the water pump 401, the water inside the box 42 can be sprayed out from the nozzle through the first connecting pipe 48 and the second connecting pipe 402.
