Abstract
The utility model relates to a wall type ventilation silencer, the internal part of which is provided with a sound-absorbing layer. The utility model is characterized in that the wall type ventilation silencer is tabular; an external surface of the wall type ventilation silencer can be served as a sound isolating layer; an air duct is in Z-shaped, and the internal part of the air duct can be provided with mutually parallel sound absorption sheets which are provided with O-N groups. The utility model has functions of ventilation, silencing, and sound insulation. The wall type ventilation silencer which has advantages of little space occupation and beautiful appearance can not only be suitable for industrial ventilation and noise reduction, but also can be particularly suitable for residential ventilation and noise reduction.
Description
The utility model belongs to the environmental protection silencing equipment, is specifically related to a kind of wall type ventilation silencer.
The employed ventilation silencer in this area all is a column at present, and promptly Cylinder, cuboid etc. during use, mostly are installed in it on wall or the partiting sound member, only have the noise elimination ventilation function, and it is big, not attractive in appearance again to take up room, and only limits to industrial use.And the silencing equipment of civilian construction still belongs to blank at present, and this makes the resident of some dwelling houses of city stand interference of noise for a long time.Therefore, develop civilian silencing equipment, become a new problem in present environmental protection field.
The purpose of this utility model just provides a kind of residential houses and other buildings of being applicable to and uses, and has the wall type ventilation silencer of ventilation, sound insulation, noise elimination function simultaneously.
Have absorbent treatment in this wall type ventilation silencer, its shape is tabular, and its external surface can be as soundproof course, and ventilation stack is the Z font, and O-N acoustical plate parallel to each other is housed in the ventilation stack.
When using the thin-sheet metal, need add one deck damping material, as damping material, to suppress the excited vibration of metal sheet roof covering at the metal sheet inwall as the shell of this wall type sound absorber.
Strengthen noise reduction as needs, can in passage, load onto several groups of acoustical plates more;
Its import and export can be adorned door, so that indoor heat insulating or ventilation also can prevent that toy from entering or being stopped up by foreign matter importing and exporting screening.If in importing and exporting passage, exhaust fan is installed, can make indoor quick ventilation, improve indoor air environment.
The utility model can directly embed wall when installing or be installed in by the window, become one with wall or window or other partiting sound member, like this, both had the function of ventilating and eliminating the noise, can bring into play the distinctive sound insulation function that wall or other partiting sound member and the utility model flat structure are brought again, it is little to take up room, elegant in appearance, be not only applicable to the industrial ventilation noise reduction, be particularly useful for the ventilation noise reduction of residential houses.
Below in conjunction with accompanying drawing in detail the utility model is described in detail:
Accompanying drawing is that the utility model is installed in an embodiment in the wall 1.
Present embodiment is to use metal sheet roof covering as shell, it is soundproof course 2, be stained with one deck damping material 3 at the metal sheet roof covering inwall, so that reduce the vibration that metal sheet roof covering is excited to cause, adjacent with damping material is absorbent treatment 4, can form by the sound absorption construction or the sound absorption material of routine, in order more effectively to eliminate noise, reach good noise reduction, present embodiment is equipped with one group of acoustical plate 9 in ventilation stack, in import and export door 6 is housed, need ventilation or when insulation when indoor, can open or close this door, in addition, gauze 7 also is housed, enters air channel 5 to stop toy or other foreign matters.Exhaust fan 8 in the air channel can make indoor quick ventilation, to improve indoor air environment.
Another embodiment of the present utility model is 3 groups of acoustical plates to be housed, with its noise elimination noise reduction effect of further enhancing in ventilation stack.Surplus with aforementioned embodiment.
Claims (3)
