The shock pad is laid at the bottom of the bag-type dust collector and the exhaust fan. The soundproof cover is bolted to the shock pad through connecting feet and bolts.
[0006] Specifically, the bag-type dust collector and the exhaust fan are connected by a pipeline.
[0007] Specifically, the soundproof cover is a multi-layer structure composed of an outer soundproof board and an inner filling layer. The soundproof cover has openings at both ends to facilitate the sleeve of the soundproof cover outside the exhaust fan. The side of the soundproof cover is provided with an observation window.
[0008] Specifically, the soundproof board is made of gypsum board material and is divided into two layers with a filling layer in between.
[0009] Specifically, the filling layer is made of soundproof felt material and is placed between the two layers of soundproof boards to achieve maximum sound insulation and noise reduction effect.
[0010] Specifically, the shock pad is made of rubber material and is laid under the dust removal and exhaust system. The shock pad reduces noise by reducing the vibration of the bag-type dust collector and the exhaust fan.
[0011] The utility model has the advantages of the following beneficial effects:
[0012] The dust exhaust system noise reduction device has the advantages of the following beneficial effects: BRIEF DESCRIPTION OF DRAWINGS
