[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-4 , the utility model provides a technical solution:
[0020] A noise-absorbing and noise-reducing generator set comprises a noise-absorbing outer shell 1, the outer shell of the noise-absorbing outer shell 1 is sleeved with a side end cover 2, a side position of the side end cover 2 away from the noise-absorbing outer shell 1 is connected to a first side interface 3, an inner side thread of the first side interface 3 is connected to an externally threaded sleeve 5, one side of the externally threaded sleeve 5 is fixedly connected to a limiting clamping ring 7, the other side of the externally threaded sleeve 5 is fixedly connected to a conical side clamping ring 6, a limiting collar 8 is provided on the outside of the limiting clamping ring 7, a side position of the limiting collar 8 away from the externally threaded sleeve 5 is fixedly connected to a conical filter screen 9, and a side position of the side end cover 2 close to the noise-absorbing outer shell 1 and the outside of the noise-absorbing outer shell 1 are respectively fixedly connected to flanges 13.
[0021] like Figure 1 and Figure 2As shown, a side position of the silencer outer shell 1 away from the side end cover 2 is connected to a second side interface 14, and a side position of the second side interface 14 away from the side position of the silencer outer shell 1 is connected to a smoke exhaust pipe body 11, and the exhaust port of the smoke exhaust pipe body 11 is arranged in an oblique cut structure. When the smoke exhaust pipe body 11 is extended to the outdoors for use, the oblique cut structure of the exhaust port can prevent rainwater from entering the inside of the pipe; the inner diameter of the side end cover 2 is set to be equal to the outer diameter of the silencer outer shell 1, and a silencer inner core body 10 is clamped and installed on the inner side of the side end cover 2, and the silencer inner core body 10 extends to the interior of the silencer outer shell 1, and the inner surface of the silencer outer shell 1 and the outer surface of the silencer inner core body 10 are fitted together, and the silencer inner core body 10 is provided on the inner side of the silencer inner core body 10. After being fitted and inserted into the interior of the silencer outer shell 1 and being fixed by the flange between the side end cover 2 and the silencer outer shell 1 to obtain an assembly limit, it will be convenient for the entire generator set to use the silencer inner core body 10 with a microporous structure on the surface to effectively reduce the noise generated when the exhaust gas is discharged during the exhaust process in the later stage; the first side interface 3 is connected to a switching elbow 4 at a side away from the side end cover 2, and a bellows 12 is connected to the end position of the switching elbow 4. The shape of the switching elbow 4 is an "L"-shaped structure. When the entire smoke exhaust assembly is connected to the boost pipeline of the generator set, the bellows 12 not only plays a certain switching role, but also can, to a certain extent, eliminate the stress caused to the supercharger when the smoke exhaust assembly is connected.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, there is a conducting arrangement between the external threaded sleeve 5 and the tapered side snap ring 6, the tapered side snap ring 6 is arranged in a structure gradually recessed toward the middle position, the outer diameter of the tapered side snap ring 6 is arranged to coincide with the inner diameter of the first side interface 3, the pointed cone end of the tapered filter screen 9 extends to the interior of the silencer inner core body 10, the outside of the limiting snap ring 7 is provided with an external threaded structure threadedly connected to the limiting sleeve 8, and when the exhaust gas enters the first side interface 3, the tapered side snap ring 6 is arranged in a structure gradually recessed toward the middle position, which will play a certain auxiliary guiding role in the circulation of the exhaust gas.
[0023] Working process: Before the device of the utility model is used, the flange assembly at the bottom of the bellows 12 can be used to quickly connect the booster pipeline of the generator set. When the entire noise reduction generator set is in operation, as the generator set generates power by igniting diesel and drives the motor rotor to rotate at high speed to generate electricity, the high-temperature exhaust gas generated during the operation will enter the exhaust pipeline composed of the flange 13, the adapter elbow 4, the silencer outer shell 1 and the exhaust pipe body 11 through the booster pipeline to be discharged outwardly, and the high-temperature exhaust gas is sent to the inside of the adapter elbow 4. When entering the interior of the first side interface 3, under the connection limitation of the first side interface 3, the limiting ring 8 and the limiting clamping ring 7, as the conical side clamping ring 6 pre-guides the high-temperature exhaust gas to a centralized manner and enters the interior of the external threaded sleeve 5, the conical filter screen 9 effectively filters the impurities in the high-temperature exhaust gas, and the filtered impurities will be concentrated in the aggregate space formed by the external threaded sleeve 5 and the conical side clamping ring 6 for subsequent centralized treatment. Finally, the exhaust gas after the impurities are filtered will be silenced and discharged through the interior of the silencer outer shell 1 and the smoke exhaust pipe body 11 in turn.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
