Abstract
The utility model relates to a ventilating noise silencer comprises an air outlet flange, an air inlet flange, a blower and a tank body, wherein the air outlet flange and the air inlet flange are fixedly connected to the tank body; the blower is fixedly connected inside the tank body comprising an air outlet channel, a silencing air channel and an air inlet channel; the tank body is provided with a thin metal sheet used as a keel at a middle; porous absorbing materials are coated outside the tank body; an outermost layer is the structure of a perforated metal sheet; one end of the air outlet channel is connected with the silencing air channel; one end of the air inlet channel is connected with the silencing air channel. The ventilating noise silencer of the utility model adopts the s-shaped silencing air channels connected end-to-head to enhance silencing quantity, and adopts the thin metal plate as the keel; the utility model is attached to the porous absorption materials and the perforated metal structure. Thus, the utility model not only ensures the strength of the tank body but also improves the noise absorbing effect; wire meshes are additionally arranged between the air inlet flange, the air outlet flange and the tank body, which prevents mosquitoes from going in; thus, the normal work of the utility model is ensured.
Description
Technical field
The utility model relates to a kind of noise abatement equipment, concretely, relates to a kind of wall type ventilation silencing apparatus.
Background technology
The ventilation silencing apparatus has been widely used in industry and the commercial building, yet the general volume of ventilation silencing apparatus of the prior art is bigger, is not suitable for average family.Also be useful on the ventilation silencing apparatus of the small size of family in the prior art, but its sound deadening capacity is very little, the noise elimination poor effect.
The utility model content
The utility model is intended to overcome deficiency of the prior art, and a kind of ventilation silencing apparatus that can increase substantially sound deadening capacity is provided.
For achieving the above object, ventilation silencing apparatus of the present utility model comprises exhaust outlet flange, air inlet flange, exhaust blower and casing, described exhaust outlet flange and air inlet flange are fixed on the casing, described exhaust blower is fixed on box inside, described casing comprises exhausting duct, noise elimination air channel and air inlet duct, casing is made substrate for the intermediate thin metallic plate, outsourcing sound-absorbing porous material, the structure of the attached perforated plate of outermost layer; Described exhausting duct one end links to each other with described noise elimination air channel; The noise elimination air channel comprises at least three S type air channels, and the S type air channel in every group is end to end, and air inlet duct one end links to each other with the noise elimination air channel.
Further, described exhausting duct is a cross-section variation structure at least once.
Further, the S type air channel in described noise elimination air channel is that cross-sectional area changes twice structure at least.
Further, described sound-absorbing porous material is block of glass wool or rock cotton board or mineral wool board outsourcing glass wool cloth or entrant sound nonwoven.
Further, described exhaust outlet flange, air inlet flange are being equipped with woven wire with the casing junction.
The end to end S type noise elimination air channel that ventilation silencing apparatus in the utility model adopts and the change of air channel cross-sectional area have improved sound deadening capacity greatly, adopt metal sheet to make substrate, go up the structure of attached sound-absorbing porous material and perforated plate, not only guaranteed the intensity of casing, also improved acoustically effective, advancing, placing woven wire between exhaust outlet flange and casing, prevented entering of mosquito, thereby guaranteed that this device can operate as normal.
