Further, metal decking described in the utility model adopts the metal sheet roof covering with anti-corrosion ability to make.
Further, insect repellent described in the utility model adopts glass fibre mat, glass fibre mat has that acoustic absorptivity is large, corrosion-resistant, Anti-moth-eating, anti-ly go mouldy, the feature such as fire-retardant, quality is light, both reached sound-absorbing effect, can effectively suppress again growing of cigarette worm.
Further, sound absorption packed layer described in the utility model adopts polyester fiber acoustical cotton, polyester fiber acoustical cotton is a kind of nontoxic, harmless, free of contamination sound-absorbing material, have that acoustic absorptivity is high, sound insulation value good, heat insulation, fire-retardant, lightweight, not containing features such as formaldehyde, be highly suitable for this place higher to environmental requirement of cigarette industry.
Further, metal decking described in the utility model surface is provided with plurality of through holes.
Further, the diameter of through hole described in the utility model adopts the aperture of 1.0mm, 1.5mm, 2.0mm.
The utility model advantage is compared with prior art:
1, good sound absorbing capabilities.According to different demands, by adjust panel bending height, change the thickness of sound absorption packed layer, and adjust the mode such as size that cavity is installed, sound absorbing module can reach more than 0.95 sound absorption coefficient.
2, good fireproof performance.Metal decking, the glass fibre mat with fireproof performance, polyester fiber acoustical cotton and damping sheet, make the fire protection flame retarding grade of this sound absorbing module reach B1 level.
3, suppress cigarette worm function.Glass fiber paper has good insect protected function, and special aperture and closely knit structure make cigarette worm cannot enter into sound absorbing module to survive.
4, decoration, workshop function.This sound absorbing module has carried out particular design to the layout in hole, and the workshop wall and the top that have made to install module have more aesthetic feeling.
5, stable quality and efficiently installing/dismounting, cleaning.Complete in factory the sound absorbing module of producing and assemble completely and have more stable quality, special structure design has guaranteed conveniently installing/dismounting and cleaning.

The specific embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Embodiment 1:
As shown in Figure 1 and Figure 2, a kind of cigarette factory's wraparound workshop dedicated suction sound module, be made up of metal decking 1, insect repellent 2, sound absorption packed layer 3, damping layer 6, described panel 1 adopts anti-corrosion metal sheet roof covering that 0.8～1.2mm is thick to be made into have the box body that one side is opening, be convenient to filling sucting sound material etc.; The thickness of its material is determined according to the size of module, and on panel, have plurality of through holes 5, there is decoration function, through-hole diameter has respectively tri-kinds of 1.0mm, 1.5mm and 2.0mm, plate face punching rate reaches 10%, guarantee broad band sound absorption ability, the especially acoustical absorptivity to low-frequency noise, and aperture below 2.0mm can prevent that the adult of cigarette worm from climbing into.
Described sound absorption packed layer 3 is filled in metal decking 1, and sound absorption packed layer 3 adopts environmental protection sound absorption material---polyester fiber acoustical cotton (claiming again environment friendly acoustical absorption cotton).Environment friendly acoustical absorption cotton is a kind of nontoxic, harmless, free of contamination sound-absorbing material, have that acoustic absorptivity is high, sound insulation value good, heat insulation, fire-retardant, lightweight, not containing features such as formaldehyde, be highly suitable for this place higher to environmental requirement of cigarette industry;
Described insect repellent 2 is arranged on the inner surface of metal decking, and is placed between sound absorption packed layer 3 and metal decking 1 inner surface, and insect repellent 2 adopts glass fibre mat (glass fiber paper).Glass fibre mat has that acoustic absorptivity is large, corrosion-resistant, Anti-moth-eating, anti-ly go mouldy, the feature such as fire-retardant, quality is light, both reached sound-absorbing effect, can effectively suppress again growing of cigarette worm;
Described damping layer 6 is fixed on the opening part of box body by press strip 4, damping layer is very good to the attenuating of the very strong low-frequency noise of penetration power, with the complementation of polyester fiber acoustical cotton, forms the acoustical absorptivity of module full frequency band.Sound absorbing module is installed the cavity that can leave a 30～50mm between rear damping layer and metope, and this cavity has good attenuation to noise, has further improved the acoustically effective of sound absorbing module.Damping layer has served as the encapsulant of acoustical cotton simultaneously, and damping layer surrounding is used press strip to fix.
The utility model sound absorbing module completely completes and produces and assembling in factory, and both instant packed transportations, can guarantee again product quality.While needing cleaning, individual module can be opened from the back side, be taken out polyester fiber acoustical cotton and clean, the laying dust in panel hole purges with compressed air.
The utility model sound absorbing module is directly positioned over T shape keel while being used for workshop furred ceiling, during for metope, need to solve its installation question.As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, while installation for metope, there are two kinds of mounting meanss:
A kind of is the mounting means that does not stay gap between module and module.Method is at four jiaos of reserved macropores of module faceplate, sees through after macropore is fixed module and with cork 9, macropore is clogged with self-tapping screw 10.Its mounting means is as Fig. 3, and the effect after installation is as Fig. 4.
Another kind is that module is not stayed gap between upper and lower, reserves the mounting means in 20mm gap between left and right.Method is to change the press strip vertical back side 4 into special bending press strip, and module reserves 20mm gap between left and right, uses C shape press strip 11 to push down special bending press strip, more fixing with self-tapping screw 10.Its mounting means is as Fig. 5, and the effect after installation is as Fig. 6.
But the above-mentioned specific embodiment is exemplary, be to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.
