Abstract

The invention provides a sound insulation and noise reduction device of a draught fan. The sound insulation and noise reduction device comprises a motor air opening silencer, a coupler silencer, a soft coupling sound insulation jacket, a draught fan body sound insulation jacket and an air flue sound insulation package, wherein the motor air opening silencer is arranged at the position of an air opening of a motor so as to conduct noise reduction on inlet and outlet air of the draught fan, the coupler silencer is arranged on a coupler connected with the motor and a draught fan body so as to conduct noise reduction on the coupler, the soft coupling sound insulation jacket is arranged on a ventilation channel between the draught fan body and an air flue so as to conduct sound insulation and noise reduction on an air flue soft coupling, the draught fan body sound insulation jacket is arranged on the draught fan body so as to conduct sound insulation and noise reduction on the draught fan body, and the air flue is wrapped by the air flue sound insulation package so as to conduct sound insulation and noise reduction on the air flue. According to the sound insulation and noise reduction device of the draught fan, various noise sources can be effectively insulated and reduced in a targeted manner, the appearance is attractive, space is saved, and overhauling and maintaining are more convenient.

Description

technical field [0001] The invention relates to the field of fans, in particular to a sound insulation and noise reduction device for fans. Background technique [0002] According to relevant data, the main harm of noise to the human body is to damage the auditory system. When the noise level exceeds 100 decibels, it can cause hearing damage. Mild hearing impairment is mainly manifested as mild tinnitus. If it develops further, it can affect speech and hearing to a certain extent, resulting in hearing difficulties in work, study and life. Sometimes a loud noise can cause temporary deafness in both ears, accompanied by severe tinnitus and vertigo. In addition, noise also affects other systems of the human body, mainly manifested as headache, dizziness, insomnia, dreaminess, memory loss, even unstable blood pressure or insufficient blood supply to extremities, nutritional disorders, and arrhythmia. Therefore, the control of excessive noise can improve the working environmen...
