Abstract
The utility model relates to a silencer for lowering noise, which is arranged on an airflow channel or an intake system and an exhaust system of air power equipment and comprises an air inlet pipe and a silencer shell. Through holes are uniformly distributed on the air inlet pipe. One end of the air inlet pipe is sealed and the other end of the air inlet pipe is provided with an opening. The silencer shell is in a tubular shape. The seal end which is the upper end of the silencer shell is provided with a baffle plate which forms an interval with the seal end of the silencer shell. At least one piece of sound absorbing piece is arranged in the interval. Compared with the traditional silencer, the silencer adds a sound absorbing measure, thereby obtaining more attractive appearance and better silencing effect. Accordingly, the limited requirement for sounds of cities is satisfied.
Description
Technical field
The utility model relates on a kind of air-flow path that is installed in aerodynamic force equipment or the silencing apparatus of the reduction noise in the inlet and exhaust system.
Background technique
Be installed in the market aerodynamic force equipment especially on the air-flow path of blower and air compressor or the silencing apparatus of the reduction noise in the inlet and exhaust system be micropole diffusor, its principle is that frequency spectrum with jet noise is a foundation, replace with a lot of little spouts if the gross area of maintenance spout is constant, when the frequency spectrum of air-flow during through small holes, jet noise will be shifted to high frequency or ultra-high frequency, audible sound composition in the frequency spectrum is obviously reduced, thereby reduce interference and injury to the people, but this silencing apparatus outward appearance is not attractive in appearance, and the noise elimination effect neither be fine.
Summary of the invention
The purpose of this utility model is to provide a kind of appearance looks elegant, on the air-flow path that is installed in aerodynamic force equipment of noise elimination better effects if or the silencing apparatus of the reduction noise in the inlet and exhaust system.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of silencing apparatus, comprise suction tude and noise elimination housing, be evenly equipped with through hole on the described suction tude, the one end is a closed shape, its the other end is provided with opening, and described noise elimination housing is a tubulose, and the closed end of described noise elimination housing is that its upper end is provided with baffle plate, form spacing between the closed end of described baffle plate and noise elimination housing, be provided with the sound absorption plate of a slice at least in this spacing.
Said sound absorption plate is made of two-layer surface layer and the absorbent treatment that is clipped between two surface layers.
Vertically paralleling of the unilateral and noise elimination housing of described sound absorption plate.
Described absorbent treatment is the ultra-fine fibre glass cotton.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: the utility model is compared with conventional muffler, has increased the sound absorption measure, and outward appearance is more attractive in appearance by contrast, the noise elimination better effects if, thus satisfied the requirement for restriction of city to the sound.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of silencing apparatus, comprise suction tude 1 and noise elimination housing 2, be evenly equipped with through hole 11 on the described suction tude 1, the one end is a closed shape, its the other end is provided with opening, described noise elimination housing 2 is a tubulose, the closed end of described noise elimination housing 2 is that its upper end is provided with baffle plate 21, form spacing between the closed end of described baffle plate 21 and noise elimination housing 2, be provided with the sound absorption plate 22 of a slice at least in this spacing, said sound absorption plate 22 is made of two-layer surface layer and the absorbent treatment 23 that is clipped between two surface layers, vertically paralleling of the unilateral and noise elimination housing 2 of described sound absorption plate 22, described absorbent treatment 23 is the ultra-fine fibre glass cotton.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
