Abstract
The utility model relates to a sound absorption and insulation cover comprising a fixed support, a sound absorption and insulation plate, a sound insulation door, and a ventilation and heat dissipation system. The sound absorption and insulation plate is fixed at the fixed support; and sealed rubber strips are arranged at positions where the surrounding of the sound insulation door is adjacent to the sound absorption and insulation plate. The sound insulation door is movably connected to the fixed support; the ventilation and heat dissipation system is arranged at the sound absorption and insulation plate; and a sound insulation observation window is arranged at the sound absorption and insulation plate. The sound absorption and insulation plate includes an outer surface layer, an inner surface layer and an interlayer; an outer erosion-resistant layer is arranged at an outer surface of the outer surface layer; an inner erosion-resistant layer is arranged at an inner surface of the inner surface layer; and the interlayer is formed by a sound absorption cotton plate and flame-retardant fiber cloths coat the inner and outer walls of the sound absorption cotton plate. According to the utility model, the sound absorption and insulation plate has the advantages of high strength, excellent acoustic performance and low cost and the like; a noise source is completely covered in the sound absorption and insulation cover; L-shaped dissipative mufflers of an air intake and an air outlet are arranged outside the sound absorption and insulation cover, so that a whole heat dissipation and ventilation problem is solved, the sound reduction index is ensured to be large, and the whole sound insulation effect is good.
Description
Technical field
The utility model relates to the noise opertaing device, especially a kind of sound absorption cover for big machinery.
Background technology
At present, the sound absorption cover is widely used in various generators, blower fan, motor, water pump, punch press and bowl mill etc. towards periphery on the strong noise plant equipment of environmental radiation noise energy, to reduce noise to the pollution of environment.The sound absorption cover is a comprehensive administration project, generally adopts noisy modes such as sound insulation, sound absorption and noise elimination.In order to make the sound absorption cover reach whole defening effect preferably, selecting a kind of is necessary for the manufacture of sound absorption cover and intensity and acoustical behavior is excellent, cost is low and defening effect is good Felt.
Summary of the invention
Advantages such as the utility model will solve the shortcoming of above-mentioned prior art, and a kind of sound absorption cover for big machinery is provided, and its Felt has intensity and acoustical behavior is excellent and cost is low, the whole defening effect of sound absorption cover that forms with its Felt manufacturing is good.
The utility model solves the technical scheme that its technical matters adopts: this sound absorption cover, comprise fixed support, Felt, soundproof door and aeration radiation system, Felt is fixed on the fixed support, be equipped with sealing rubber strip with the Felt adjacent around the soundproof door, soundproof door is movably connected on the fixed support, aeration radiation system is located on the Felt, is provided with the sound insulation view window at Felt; Felt comprises outer surface layer, interior surface layers and middle layer, the outside surface of outer surface layer is provided with external anti-corrosion layer, the inside surface of interior surface layers is provided with interior anticorrosive coat, and the middle layer mainly is made of the cotton plate of sound absorption, is enclosed with fire resistance fibre cloth on the inside and outside wall of the cotton plate that absorbs sound.Like this, advantage such as its Felt has intensity and acoustical behavior is excellent and cost is low, the whole defening effect of sound absorption cover that forms with its Felt manufacturing is good.
Further, outer surface layer thickness is 2mm, and interior surface layers thickness is 0.8mm, and intermediate layer thickness is 80mm, and sound absorption cotton board material material is centrifugally glass-wool or rock wool.Like this, the Felt that its manufacturing forms is effective, can be other thickness also, as long as reach the condition for the manufacture of the sound absorption cover.
Aeration radiation system comprises air inlet and air outlet, and air inlet is located at the below of sound absorption cover, and air outlet is located at the top of sound absorption cover, is equipped with L type dissipative muffler on air inlet and the air outlet.Like this, aeration radiation system adopts bottom air intake, top air draft, makes the air-flow circulation more smooth and easy, and the air flow stream general character is good in the sound absorption cover, even motor during normal operation, also can keep lower temperature in the sound absorption cover under hot environment.
The effect that the utility model is useful is: advantage such as Felt of the present utility model has intensity and acoustical behavior is excellent and cost is low, noise source all is coated in the sound absorption cover, the L type dissipative muffler of air inlet and air outlet all is located at outside the sound absorption cover, solved the integral heat sink ventilating problem, the assurance oise insulation factor is big, and whole defening effect is good.
