Detailed Description
The conception, the specific structure and the technical effects of the present invention will be clearly and completely described in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the schemes and the effects of the present invention.
As shown in fig. 1-2, the vertical upper exhaust silencer of the present invention requires 8 shell assemblies to be assembled, and a shell 9 of the shell assembly includes an anticorrosive layer 7, a sound insulation layer 6, an inner porous plate 1, and a rectifying plate 5 transversely disposed between the sound insulation layer 6 and the inner porous plate 1. The sound insulation layer 6 and the inner porous plate 1 are of a hollow structure, and the rectifying plate 5 is fixed between the sound insulation layer and the inner porous plate through welding or self-plugging rivets 11. The thickness of the shell of the silencer is 147-150 mm.
The outer surface of the silencer is plated with 180g/m zinc on the side sealing plate 2 to form an anticorrosive layer 7, so that various external severe environments can be well resisted, and an anticorrosive effect is achieved; the soundproof layer 6 is a soundproof layer filled with soundproof cotton, has waterproof and flame retardant effects, and is bonded to the anticorrosive layer 7. The rectifying plate 5 and the inner porous plate 1 both adopt 430 stainless steel porous plates.
As shown in fig. 1-2, the muffler of the present invention is formed by assembling a plurality of shell assemblies into an internal hollow square shell through pillars 4, connecting strips 3, etc. (the pillars 4 are arranged at four corners of the square shell). The upright post 4 is in a folded edge form. The surface of shell subassembly is equipped with connecting strip 3 along the silencer radial direction, and it adopts 4# square tube to make and forms, mainly does and strengthens the box and reduce the resistance, lets the air current more smooth and orderly. The surface of shell subassembly is equipped with reinforcing bar 8, reinforcing bar 8 set up the direction with the connecting strip is perpendicular.
As shown in FIG. 3, the inner porous plate 1 has staggered holes, the diameter of each hole is 3mm, the distance between two horizontally adjacent holes is 6mm, and the distance between two vertically adjacent holes is 5 mm.
