Sound insulation device suitable for coal mill and method

Abstract

A sound insulation device suitable for a coal mill includes a steel structure sound insulation skeleton, a sound insulation cover is fixedly arranged on the steel structure sound insulation skeleton, a sound insulation board from which the sound insulation cover is prepared comprises a FC (fiber cement) board composite layer and an impedance composite sound absorbing material layer; the impedance composite sound absorbing material layer comprises a wavy perforated aluminum plate and a sound absorption non-woven cloth layer, the sound absorption non-woven layer is internally packaged and provided with a first superfine glass cotton layer; the FC (fiber cement) board composite layer is arranged on the inner side of the wavy perforated aluminum plate, the FC (fiber cement) board composite layer comprises two FC boards, a second superfine glass cotton layer is arranged between the two FC boards, and a light steel keel for fixing the second superfine glass cotton layer is arranged on the edge of the two FC boards. The invention also discloses a method for using the sound insulation device for sound insulation. The sound insulation device has the advantages of good sound insulation and sound absorption effects, light weight, convenient use and reasonable design.

Description

technical field The invention relates to a sound insulation device suitable for coal mills, belonging to the technical field of noise treatment devices; the invention also relates to a sound insulation method using the aforementioned sound insulation device. Background technique There is serious noise pollution during the operation of existing mechanical equipment, and the main technology for noise prevention and control is to isolate mechanical equipment from the external environment through sound insulation devices. Sound insulation devices have become an important component of comprehensive noise control, thereby reducing the amount of noise. To achieve the effect of sound insulation and noise reduction. There are various types of sound insulation devices in the prior art, but the overall sound insulation effect is not ideal, and cannot meet the environmental protection requirements of industrial enterprises. Especially for coal mills, there is no sound insulation device...
