Abstract
The utility model relates to a secondary silencer of a silencer used for a generator set, which is characterized in that the secondary silencer of the silencer used for the generator set is provided with a shell (1), a middle baffle (2) is arranged in the shell (1), the shell is divided into a first cavity (3) and a second cavity (4) by the middle baffle (2), a through hole (5) is arranged in the middle baffle (2) to communicate the first cavity (3) with the second cavity (4), an inlet hole (6) is arranged in the shell of the first cavity (3), and a tail pipe (7) is arranged on the shell of the second cavity (4). As a resistance expanded type silencer is adopted and additionally mounted on the original silencer, the obvious silencing effect is guaranteed. Being matched with a ventilating-radiating air channel, the silencing effect can be lower than 80dB.
Description
Technical field
The utility model belongs to the generator set technical field, relates in particular to the secondary muffler of a kind of generator set with silencing apparatus.
Background technique
Along with deepening continuously of development of science and technology and basic scientific research, new material and The application of new technique have played bigger impetus to the development of generator set.But the air-cooled generator silencing apparatus of present some all is single, and noise reduction is not obvious, causes the generator set noise big and influence surrounding environment.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned existing technology; The secondary muffler of a kind of generator set with silencing apparatus is provided, and the technological scheme that the purpose of realization the utility model is taked is: the utility model is an expansion silencing apparatus that cooperates former silencing apparatus, and this generator set is provided with a housing with the secondary muffler of silencing apparatus; Be provided with central diaphragm in the housing; Central diaphragm is divided into first cavity and two cavitys of second cavity with housing, has through hole on the central diaphragm, and first cavity is connected with second chamber; Have inlet hole on the housing of first cavity, the housing of second cavity is provided with tailpipe.Housing is provided with mounting bracket, is convenient to be connected with former silencing apparatus.
The utility model adopts resistance expanssion type silencing apparatus, is installed on the former silencing apparatus, has guaranteed the explicitly of noise elimination effect, cooperates the ventilation and heat air channel, and the noise elimination effect is reached below the 80dB.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the appearance structure schematic representation of the utility model;
Fig. 3 is that the utility model is connected schematic representation with former silencing apparatus.
Among the figure, 1, housing, 2, central diaphragm, 3, first cavity, 4, second cavity, 5, through hole, 6, inlet hole, 7, tailpipe, 8, mounting bracket, 9. former silencing apparatus.
Embodiment
With reference to accompanying drawing; This generator set is provided with a housing 1 with the secondary muffler of silencing apparatus, is provided with central diaphragm 2 in the housing 1, and central diaphragm 2 is divided into first cavity 3 and 4 two cavitys of second cavity with housing; Have through hole 5 on the central diaphragm 2; First cavity 3 is connected with second chamber 4, and the housing that has inlet hole 6, the second cavitys 4 on the housing of first cavity 3 is provided with tailpipe 7.Housing 1 is provided with mounting bracket 8, is convenient to be connected with former silencing apparatus.
During use; The inlet hole 6 of secondary muffler is enclosed within on the tailpipe of former silencing apparatus 9, and is fixed on the former silencing apparatus 9 with mounting bracket 8, the tail gas of discharging from former silencing apparatus 9 gets in first cavity 3 through inlet hole 6; Because the unexpected increase in cross section, noise descends.Gas gets in second cavity 4 from the through hole 5 on the central diaphragm 2 then, and noise is further descended.At last, the gas of second cavity 4 is discharged from tailpipe 7, and at this moment, noise more obviously descends.
Claims (2)
1. a generator set is with the secondary muffler of silencing apparatus; It is characterized in that: this generator set is provided with a housing (1) with the secondary muffler of silencing apparatus; Be provided with central diaphragm (2) in the housing (1); Central diaphragm (2) is divided into first cavity (3) and (4) two cavitys of second cavity with housing, has through hole (5) on the central diaphragm (2), and first cavity (3) is connected with second chamber (4); Have inlet hole (6) on the housing of first cavity (3), the housing of second cavity (4) is provided with tailpipe (7).
