Description
Technical field
This utility model relates to a kind of spraying machine, more specifically, particularly relates to a kind of environmental protection wind spraying aid type spray for dust suppression machine with noise reduction assembly.
Background technology
The noise reduction of the axial flow blower of the air-assisted type spraying machine used on domestic market mostly uses glass fibre to make sound-absorbing material, but owing to it is not provided with noise reduction assembly at air inlet, or it is too short to arrange noise reduction assembly, and erasure effect is the most not ideal, and noise is the biggest.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, to change original noise reduction modular construction, it is provided that a kind of compact conformation, the environmental protection wind spraying aid type dust removing sprayer of good muffling effect.
The technical solution adopted in the utility model is as follows: a kind of environmental protection wind spraying aid type spray for dust suppression machine with three grades of silencing means, including air duct, in described air duct, blower fan is installed, the air inlet of described blower fan is provided with deafener, described deafener includes more than 1 noise reduction assembly, connect at the air outlet of described air duct and have cone air duct, it is provided with air deflector cone cylinder in described cone air duct, described noise reduction assembly and air deflector cone cylinder are made by the above mesh plate of two-layer, described air duct and cone air duct all include outside plate and inner panel, described inner panel is mesh plate, described mesh plate is provided with mesh, sound-absorbing district is formed between described adjacent two mesh plates and between outside plate and mesh plate, it is filled with sound-absorbing material in described sound-absorbing district.
Further, described noise reduction assembly be shaped as annular, waveform or polygon.
Further, the quantity of described noise reduction assembly is 2.
Further, the thickness of described mesh plate is 2-4mm, and the aperture of described mesh is 5mm, and the pitch of holes between described two mesh is 8 mm.
Further, described air deflector cone cylinder is hollow cone cylinder, fills sound-absorbing material, increase noise reduction area, improve erasure effect simultaneously in hollow cone cylinder.
Further, described sound-absorbing material is that acoutic fibre board is cotton.
This utility model adds noise-damping interfaces and amasss; there is simple in construction, low cost, the advantage that effective, level of application is high; compared with prior art; its noise reduction is significantly larger than national standard requirement; be applicable to dust pollution that the exploitation of large outdoors colliery causes and Coal Yard, transport, crush, dedusting dust suppression that the dust uncontrollable discharge such as smelting pollutes, protection environment, dedusting cooling etc. are had good practical application effect.
