Abstract

The invention relates to a high-reliability plate-type muffler, which comprises a smoke inlet pipe (1), a shell (5) and a smoke exhaust pipe (6), and is characterized in that: the shell (5) of the muffler is internally provided with two U-shaped partition boards (4), the two U-shaped partition boards (4) are oppositely arranged, the two U-shaped partition boards (4) are welded into a whole by utilizing the upper connecting board and the lower connecting board (3), the U-shaped partition boards (4) are welded onto the smoke inlet pipe (1) through the fixing board (2), and the smoke inlet pipe (1) and the smoke outlet pipe (6) are small hole type muffler pipes with tail ends being sealed and are welded on the front side wall and the rear side wall of the shell (5). The internal silencing structure of the silencer and the upper surface and the lower surface of the shell have no welding spots, so that the generation of cracks is avoided, the leakage problem of a common silencer is solved, and the silencer is particularly suitable for the fields with high requirements on silencing performance and reliability, such as small-sized silencing generator sets.

Description

High-reliability plate-type muffler
Technical Field
The invention belongs to the technical field of small-sized mute generator sets, and particularly relates to a high-reliability plate-type muffler.
Background
Along with the improvement of environmental protection requirements, noise becomes an important index for measuring the quality of the generator set, and in the noise reduction system of the generator set, the muffler plays an indispensable role, and the reliability of the muffler even determines whether the generator set can be normally used. The smoke exhausted by the engine has the characteristics of high temperature, high pressure and strong impact force, and is extremely easy to cause the cracking of the weld joint of the muffler to cause leakage failure.
Disclosure of Invention
The invention aims to solve the problem that a muffler is easy to leak due to the impact of engine smoke exhaust, and provides a high-reliability plate-type muffler. In order to achieve the above purpose, the invention adopts the following technical scheme: the utility model provides a high reliable plate type muffler, includes smoke tube, casing and exhaust pipe, its characterized in that: the shell of the muffler is internally provided with two U-shaped clapboards, the two U-shaped clapboards are oppositely arranged, the two U-shaped clapboards are welded into a whole by utilizing an upper connecting plate and a lower connecting plate, the U-shaped clapboards are welded onto a smoke inlet pipe through a fixing plate, the smoke inlet pipe and the smoke outlet pipe are small hole type silencing pipes with tail ends closed, the small hole type silencing pipes are welded on the front side wall and the rear side wall of the shell, superfine glass wool is densely filled in a cavity of the shell, and silicone heat-conducting glue is uniformly smeared on the contact surface of the clapboards and the shell.
The invention relates to a high-reliability plate-type muffler, which is particularly suitable for the fields of small-sized mute generator sets and the like with higher requirements on mute performance and reliability.
Drawings
FIG. 1 is a front view of a schematic construction of the present invention;
fig. 2 is a cross-sectional view A-A of fig. 1.
In the figure, a smoke inlet pipe 1, a fixing plate 2, a connecting plate 3, a U-shaped partition plate 4, a shell 5 and a smoke exhaust pipe 6.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings.
The utility model provides a high reliable plate type muffler, includes advances tobacco pipe 1, casing 5 and exhaust pipe 6, its characterized in that: the shell 5 of the muffler is internally provided with two U-shaped partition boards 4, the two U-shaped partition boards 4 are oppositely arranged, the two U-shaped partition boards 4 are welded into a whole by utilizing the upper connecting board 3 and the lower connecting board 3, the U-shaped partition boards 4 are welded to the smoke inlet pipe 1 through the fixing board 2, the smoke inlet pipe 1 and the smoke exhaust pipe 6 are small hole type silencing pipes with closed tail ends, the small hole type silencing pipes are welded on the front side wall and the rear side wall of the shell 5, superfine glass wool is densely filled in a cavity of the shell 5, and silicone heat-conducting glue is uniformly smeared on the contact surface of the partition boards 4 and the shell 5.
The working process of the invention is as follows: when the air flow passes through the small holes, the frequency spectrum in the noise moves to high frequency or ultrahigh frequency, so that the audible sound component in the frequency spectrum is obviously reduced, the interference and injury to people are reduced, and resistance silencing is performed; then the air flow goes along a zigzag path formed by the two U-shaped partition boards 4 and passes through the superfine glass wool in the process, a part of sound energy is rubbed in the pores of the superfine glass wool to be converted into heat energy to be dissipated, resistive silencing is carried out, and the silicone heat-conducting glue uniformly smeared on the contact surface of the U-shaped partition boards 4 and the shell 5 can quickly dissipate the heat in the shell 5; finally, the air flow flows through the small holes on the smoke exhaust pipe 6, resistance noise elimination is performed again, and then the air flow is discharged out of the muffler.
The inner silencing structure of the silencer and the upper and lower surfaces of the shell are not provided with any welding spots, and the side surfaces of the shell with good rigidity are welded with the smoke inlet pipe and the smoke outlet pipe, so that the upper and lower surfaces of the shell with poor rigidity are not pulled by the inner silencing structure when the upper and lower surfaces are subjected to expansion and contraction and the impact of engine smoke outlet, thereby avoiding the generation of cracks and solving the leakage problem of the common silencer.
The invention relates to a high-reliability plate-type muffler, which is particularly suitable for the fields of small-sized mute generator sets and the like with higher requirements on mute performance and reliability.
