Abstract
The utility model provides a totally-closed acoustic absorption air pipe. The totally-closed acoustic absorption air pipe comprises an air pipe outer surface (1), a heat preservation acoustic absorption layer (2) and an air pipe inner surface (3), wherein the air pipe outer surface (1) is made of aluminum foil fabric or reinforced aluminum foil, the heat preservation acoustic absorption layer (2) is made of centrifugal glass wool boards, the volume weight of the centrifugal glass wool boards ranges from 48kg/m<3> to 100 kg/m<3>, the air pipe inner surface (3) is made of coated fabric, and the heat preservation acoustic absorption layer (2) is arranged between the air pipe outer surface (1) and the air pipe inner surface (3). The totally-closed acoustic absorption air pipe can effectively solve the problem of noise of a traditional air pipe, can improve the environmental protection performance, and can be widely applied to central air conditioner ventilation systems of office spaces and public places with dense population.
Description
Technical field
The utility model relates to the totally-enclosed airduct of a kind of sound-absorbing, is applied to densely populated office and the ventilating system for central air-conditioner of public place.
Background technique
Traditional central air-conditioning system ventilation airduct, what generally adopt is the additional thermal insulating material insulation of galvanized sheet iron airduct.These airducts get rusty easily and can grow many bacteriums in long-term the use, and these bacteriums are delivered to each room and place by the hot and cold wind of central air-conditioning system through air-line system.Live in for a long time in the room of this central air-conditioning system, people very easily infect breathing problem, and people's body and mind is caused to very big injury.Not only the fabrication and installation cycle is long, speed is slow for these traditional galvanized sheet iron airducts, and also need to install additional silencing apparatus to reduce the noise of equipment noise and Air Flow generation in ventilation system, not only need the reserved larger device space, and increased installation difficulty and workload.The insulation of tradition airduct adopts glass wool, rubber and plastic insulation usually, generally at airduct, installs scene and does insulation, and construction environment is severe, and the outward appearance of thermal insulation layer is also not too attractive in appearance.Although common glass fiber air pipe is changing aspect noise reduction, insulation to some extent, in the interior surface layers of airduct and airduct, four jiaos of jointings exist the risk that glass comes off.
The utility model is improved for above-mentioned airduct drawback, makes it performance and can either meet the National Fire Academy fire protection requirement and reach and do not fire the A level, can play sound absorption function simultaneously.
Summary of the invention
The utility model relates to a kind of totally-enclosed airduct of sound-absorbing with sound absorption function, is applied to densely populated office and the ventilating system for central air-conditioner of public place, and fire-protection rating reaches does not fire the A level.
The totally-enclosed airduct of described sound-absorbing comprises: airduct outer surface 1 adopts aluminium foil cloth or adds reinforced aluminium foil; Heat-preservation and sound-absorption layer 2 adopts the unit weight scope at 48Kg/m
3to 100Kg/m
3the centrifugally glass-wool plate; Airduct internal surface 3 materials are coated fabric, and described heat-preservation and sound-absorption layer 2 is between airduct outer surface 1 and airduct internal surface 3.
Preferably, the totally-enclosed airduct of described sound-absorbing is characterized in that: described airduct adopts the V-type mode of grooving.
Preferably, the totally-enclosed airduct of described sound-absorbing, the connection between airduct, adopt flange to connect or adopt the bayonet joint of male and female mouth.
The utility model product through adopting above technical matters to produce has the following advantages:
(1) the totally-enclosed airduct of sound-absorbing has excellent Safety performance.Refractory nature is good, belongs to the A level and does not fire product.
(2) the totally-enclosed airduct simple installation of sound-absorbing, good airproof performance, be easy to repair.
(3) the totally-enclosed airduct of sound-absorbing adopts the heat-preservation and sound-absorption layer of centrifugally glass-wool plate as airduct, has good sound absorption qualities.
(4) the totally-enclosed airduct of sound-absorbing adopts the male and female mouth to peg graft, and adds the Placement of chewing-gum band sealing, has the performance that low air quantity is revealed, reduced energy consumption, energy saving.
(4), accompanying drawing explanation
Fig. 1 is the stereochemical structure schematic cross-section of the totally-enclosed airduct of the utility model sound-absorbing.
Fig. 2 is the deployed configuration schematic diagram of the totally-enclosed airduct of the utility model sound-absorbing.
1 airduct outer surface
2 heat-insulating and sound-absorbing layers
3 airduct internal surfaces
(5) embodiment
Fig. 1 is the structural representation of the totally-enclosed airduct of the utility model sound-absorbing, and Fig. 2 is the deployed configuration schematic diagram of the totally-enclosed airduct of the utility model sound-absorbing, below with reference to Fig. 1 and Fig. 2, describes the utility model.
The totally-enclosed airduct of the utility model sound-absorbing, with the unit weight scope at 48Kg/m
3to 100Kg/m
3the centrifugally glass-wool plate as airduct heat-insulating and sound-absorbing layer 2, this centrifugally glass-wool plate adopts porous loose structure, has superior sound absorbing capabilities.At the one side of heat-preservation and sound-absorption layer 2 tiling aluminium foil cloth or add reinforced aluminium foil as airduct outer surface 1.Another side at heat-preservation and sound-absorption layer 2 tiles coated fabric as airduct internal surface 3, this coated fabric has good waterproof, bacteriostasis property, form totally enclosed airduct space at the airduct inner face, the glass fibre that has solved the airduct inwall easily comes off, mildew-resistant, problem that humidity resistance is lower.Heat-insulating and sound-absorbing layer 2 is done to the V-type fluting near the one side of airduct internal surfaces 3, and groove depth is less than the thickness of heat-insulating and sound-absorbing layer 2, through above-mentioned steps, is made into air duct board, air duct board is carried out bonding, form the totally-enclosed airduct of sound-absorbing.
Connection between airduct, adopt flange to connect or the bayonet joint of employing male and female mouth, wherein, the male and female mouth bayonet joint of flangeless conjunction, after joint adopts Eight characters stickfast admittedly, reusable heat sensitive tape bonding is fixing, guarantees that the nothing of airduct air quantity is leaked and soundness.The airduct of making through above technique, lightweight, simple installation.
As well known to those skilled in the art, during practical application, the totally-enclosed airduct equipment of above-mentioned sound-absorbing is a unit, the totally-enclosed airduct equipment of a plurality of above-mentioned sound-absorbings continuously, wherein the totally-enclosed airduct equipment of the sound-absorbing of two adjacency adopts flange to connect or adopts the bayonet joint of male and female mouth, to form a whole set of airduct pipeline.
