Description

Technical Field

[0001] This utility model belongs to the technical field of dust control equipment, and more specifically, it relates to a dust control dust collection hood structure. Background Technology

[0002] Currently, the common industrial dust control process mainly consists of a dust collection hood → dust collection duct → dust collector → dust collector fan → dust collection chimney. The dust collection hood, as the first step in dust control, primarily collects the dispersed dust. Through its design and layout, the dust source can be effectively confined to a small, localized space. When the hood sucks in air, a negative pressure is created inside, drawing in particles carried by the dust. After being captured by the hood, the dust is sent through the dust collection duct to the dust collection equipment. After purification, it is discharged into the atmosphere through the chimney, significantly reducing the concentration of dust in the air and minimizing environmental pollution. A common design for dust collection hoods is a square hood mounted above a material feeding trough, welded to the trough. Common problems include improper sealing or incomplete welding leading to incomplete dust collection or low efficiency. After prolonged use, dust and dirt accumulate on the dust collection hood, requiring cleaning and maintenance. During cleaning, dust may be dispersed into the air, posing a potential threat to human health.

[0003] Existing technology includes a dust collection hood entitled "A Dust Collection Hood" with publication number CN207412987U. This technology provides a dust collection hood comprising an air purifier, a side-suction hood, and a sealing curtain. The air purifier is symmetrically positioned around the side-suction hoods around the vehicle compartment, located above the compartment. At least one row of air outlets is provided on the inner wall of the side-suction hoods. The side-suction hoods are connected to ductwork, which in turn connects to a dust collector. A sealing curtain is vertically connected below the side-suction hoods. This invention solves the problem of dust collection hoods failing to meet national occupational health standards. The dust collection hood consists of an air purifier and side-suction hoods, with a sealing curtain below the side-suction hoods for sealing. The dust content in the air in the worker's facial breathing area is less than 1.5 milligrams. However, this technology does not address the technical problem and solution of this application.
