Abstract
The utility model relates to a silencing and sound insulating device for a blower room, which is used for air intake, silencing and sound insulating of a blower room. The silencing and sound insulating device comprises a sound insulating shield fixed on the outer side of an air intake window on a wall of the blower room, the lower end of the shield body of the sound insulating shield, which is an opening, extends downwards to be positioned below the air intake window on the wall, vertical sound insulating plates distributed at intervals parallelly are arranged in the extension portion of the shield body below the air intake window, and air input passages are arranged among the vertical sound insulating plates. When blowers run, external air enters the blower room continuously through the sound insulating shield via the air input passages, and noise of airflow is weakened by the silencing and sound insulating device greatly, so that silencing and sound insulating effects are realized.
Description
Technical field
The utility model relates to a kind of Ventilator Room noise elimination sound arrester, is the device that is used for the air inlet of blast fan machine room, noise elimination and sound insulation.
Background technology
Often need in the production of industry such as chemical industry, metallurgy to adopt blast fan to produce compressed air.Blast fan is in service can to produce very big noise, and not only the Ventilator Room noise is huge, and noise leaks seriously.For reducing the Ventilator Room noise, conventional way is, for blower fan installs sound insulation enclosure additional.But sound insulation enclosure is not good to noise control, the powerful pneumatic noise of the uncontrollable Ventilator Room of sound insulation enclosure particularly, sound insulation enclosure makes that equipment cooling is not good, overhaul of the equipments is inconvenient in addition, because of in actual motion, sound insulation enclosure is opened usually or removes, and does not reach the purpose of control fan noise.
Summary of the invention
At the unmanageable problem of present Ventilator Room noise, the utility model purpose provides a kind of Ventilator Room and eliminates the noise and sound arrester, can effectively reduce the Ventilator Room pneumatic noise, possesses complex functions such as air inlet, air-flow noise elimination, sound insulation, ventilation and heat simultaneously.
The utility model noise elimination sound arrester comprises the sound insulation guard shield that is fixed on the Ventilator Room body of wall air intake window outside, the cover body lower ends downward of sound insulation guard shield extends to below the body of wall air intake window and the lower end is an opening, being positioned at the following cover body extension of air intake window and being provided with the vertical sound barrier that parallel interval distributes, is air input passage between each vertical sound barrier.
The skin of the cover body of said sound insulation guard shield is that steel plate, middle level are vertical sound barriers, and internal layer has the porous steel sheet again.
The outer layer plate of said cover body is provided with and turns up in one's ear, will be connected with body of wall in one's ear by expansion bolt.
Said each vertical sound barrier porous steel sheet cotton by ultra-fine fibre glass and surface recombination is formed.
Said body of wall air intake window is equipped with a plurality of noise elimination shutter boards that be arranged in parallel, and each shutter board porous steel sheet cotton by ultra-fine fibre glass and surface recombination is formed.
Between each plate face of said noise elimination shutter board is oblique parallel or horizontal parallel.
The sound insulation guard shield of this device is installed on the wall in the Ventilator Room air intake window outside, during the blast fan operation, extraneous air stream enters in the cover through parallel air input passage from the cover body lower ending opening, enter Ventilator Room by the air intake window on the wall then, ultra-fine fibre glass porous steel sheet cotton and surface recombination has the function of sound-absorbing and sound insulation, the air stream of big flow is before entering Ventilator Room, the powerful pneumatic noise guard shield that insulated against sound is isolated, and by parallel sound barrier, cover body and shutter board are eliminated the noise and absorption of noise, neither influence the ventilation and heat of Ventilator Room air inlet and blast fan, can reach good noise elimination again, defening effect, acoustical insulation sound-deadening amount meet relevant plant area of country and the Noise Control requirement of factory circle.Compact conformation, flexible for installation, good looking appearance.
Description of drawings
Fig. 1 is the cross-sectional view of Ventilator Room noise elimination and sound arrester.
Among the figure, 1-cover body, 2-air input passage, 3-vertically sound barriers, 4-noise elimination shutter board, 5-expansion bolt, 6-body of wall, 7-outer layer plate, 7-1-outer layer plate turns up in one's ear, 8-ultra-fine fibre glass cotton, 9-porous steel sheet, 10-body of wall air intake window.
The specific embodiment
Structure below in conjunction with description of drawings the utility model oxidation fan room oise damping means.
As shown in Figure 1, body of wall air intake window 10 is equipped with noise elimination shutter board 4; The sound insulation guard shield is installed on the wall in air intake window 10 outsides of Ventilator Room body of wall 6, cover body 1 lower ends downward of sound insulation guard shield extends to the body of wall air intake window below 10, be positioned at the cover body extension of air intake window below 10 and be provided with a plurality of vertical sound barrier 3 that parallel interval distributes, each vertical sound barrier 3 parallel interval distributes, and the position is an air input passage 2 at interval.Among Fig. 1, A portion represents the cross-section structure of cover body 1.The skin of cover body 1 is that steel plate 7, middle level are ultra-fine fibre glass cottons 8, and internal layer has porous steel sheet 9 again.Each vertical sound barrier 3 is formed by the porous steel sheet 9 of ultra-fine fibre glass cotton 8 and surface recombination.In the present embodiment, each shutter board 4 of eliminating the noise is oblique parallel fixed installation (but also horizontal parallel fixed installation), and the material of each shutter board 4 is made up of the porous steel sheet 9 of ultra-fine fibre glass cotton 8 and surface recombination with vertically sound barrier 3 is identical.
During the blast fan operation, outside air enters Ventilator Room by the direction of arrow among Fig. 1 continuously through the sound insulation guard shield, and the noise of air-flow is weakened greatly by this device, reaches the effect of the sound insulation of eliminating the noise.
The outer layer plate of cover body 1 of sound insulation guard shield is provided with the 7-1 in one's ear that turns up, by expansion bolt 5 in one's ear 7-1 fix with body of wall 6.
