Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1,2,3, 4, a kind of coal mine axis stream booster honeycomb silencer provided in this embodiment, including
Silencer cylinder 7 is equipped in the upstream end of silencer cylinder 7 and exports the abutted flange 1 docked with ventilation blower, in silencer cylinder
Outlet end be equipped with the connecting end surface 6 that connects with blower air hose, the silencer cylinder is set as close to the side of abutted flange
Guarantee that the reducer 2 of flow area, silencer cylinder are set as direct tube section 4, the noise elimination of direct tube section far from the side of abutted flange
One circle canister fabric cloth 8 is installed on device cylinder inboard wall, is equipped with inside the silencer cylinder that direct tube section connects with reducer close
Sealing end face, seal face and silencer cylinder axially vertical setting are equipped with inside the direct tube section of the silencer cylinder several
