Description

Technical Field

[0001] The utility model relates to the technical field of noise control, in particular to a device for controlling noise at the boundary of a coal mine equipped with ultra-light sound-absorbing cotton. Background Art

[0002] Noise pollution refers to the acoustic environment phenomenon caused by noise sources that has adverse effects on human life, work, study, and health. With the rapid development of industrialization and urbanization, noise pollution has become one of the major environmental issues facing modern society.

[0003] Coal mining produces a lot of noise, which poses a threat to the physical and mental health of workers underground. Noise control devices are needed to reduce the noise. Currently, noise control devices are mainly made of sound-absorbing materials, which are relatively large and heavy, making them inconvenient to carry and set up underground. Moreover, when reducing noise, the device closes the space, causing ventilation difficulties, which is not conducive to underground mining work of workers. Utility Model Content

During use, the fan blades are driven to rotate at high speed by the operation of the driving device, and the fan blades can blow air when rotating at high speed, so that negative pressure is generated in the ventilation and noise reduction box, and external air enters from one end of the ventilation and noise reduction box, and is discharged from the other end of the ventilation and noise reduction box, so that air circulates, and dust can be prevented from entering the ventilation and noise reduction box through the filter.
