Abstract

The utility model relates to a high-reliability plate-type silencer, including advancing tobacco pipe (1), casing (5) and discharging fume pipe (6), its characterized in that: be equipped with two U-shaped baffle (4) in casing (5) of this silencer, two U-shaped baffle (4) set up relatively, utilize two upper and lower connecting plates (3) with two U-shaped baffle (4) welding as an organic whole to through fixed plate (2) with U-shaped baffle (4) weld advance on tobacco pipe (1), advance tobacco pipe (1) and discharge fume pipe (6) for terminal confined aperture formula muffler pipe, all weld on casing (5) front and back lateral wall. The utility model discloses an inside noise-abatement structure of silencer and casing upper and lower surface do not have any solder joint, have avoided the crackle to produce, have solved the problem of revealing of general silencer, the field that specially adapted small-size silence generator unit etc. required higher to silence performance and reliability.

Description

High-reliability plate-type silencer

Technical Field

The utility model belongs to the technical field of small-size silence generator unit, especially, relate to a highly reliable plate-type silencer.

Background

With the improvement of environmental requirements of people, noise becomes an important index for measuring the quality of a generator set, and in a noise reduction system of the generator set, a silencer plays an indispensable role, and the reliability of the silencer even determines whether the generator set can be normally used. The smoke discharged by the engine has the characteristics of high temperature, high pressure and strong impact force, and easily causes the cracking of a welded junction of the muffler to cause leakage failure.

Disclosure of Invention

The utility model aims to solve the problem that the silencer is easily leaked by the engine smoke discharge impact, provide a highly reliable plate-type silencer. In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a high reliable plate-type silencer, includes into tobacco pipe, casing and the pipe of discharging fume, its characterized in that: the casing of this silencer is equipped with two U-shaped baffles in, two U-shaped baffles set up relatively, and two connecting plates weld two U-shaped baffles as an organic whole about utilizing to weld the U-shaped baffle through the fixed plate and advance on the tobacco pipe, advance the tobacco pipe and discharge fume the pipe and be terminal confined aperture formula muffler pipe, all weld on lateral wall around the casing, closely knit packing superfine glass cotton in the casing cavity, evenly paint silicone heat-conducting glue on the contact surface of U-shaped baffle and casing.

The utility model relates to a board-like silencer of high reliable type, the higher field of requirements for silence performance and reliability such as the small-size silence generator unit of specially adapted.

Drawings

Fig. 1 is a front view of the structure diagram of the present invention;

Fig. 2 is a sectional view a-a of fig. 1.

In the figure, 1 is a smoke inlet pipe, 2 is a fixing plate, 3 is a connecting plate, 4 is a U-shaped partition plate, 5 is a shell, and 6 is a smoke exhaust pipe.

Detailed Description

The invention is described in further detail below with reference to the drawings.

the utility model provides a board-like silencer of high reliable type, includes into tobacco pipe 1, casing 5 and discharge fume 6, its characterized in that: be equipped with two U-shaped baffles 4 in the casing 5 of this silencer, two U-shaped baffles 4 set up relatively, two connecting plates 3 weld two U-shaped baffles 4 as an organic whole about utilizing, and weld U-shaped baffle 4 through fixed plate 2 and advance on the tobacco pipe 1, advance tobacco pipe 1 and discharge fume pipe 6 and be terminal confined aperture formula muffler pipe, all weld on casing 5 front and back lateral wall, closely knit packing superfine glass cotton in the 5 cavities of casing, evenly paint silicone heat-conducting glue on the contact surface of U-shaped baffle 4 and casing 5.

The working process of the invention is as follows: the smoke exhausted by the engine enters the silencer through the smoke inlet pipe 1, and when airflow passes through the small holes, the frequency spectrum in the noise moves to high frequency or ultrahigh frequency, so that audible components in the frequency spectrum are obviously reduced, the interference and the damage to people are reduced, and the reactive silencing is carried out; then, the airflow moves forward along a zigzag path formed by the two U-shaped partition plates 4 and passes through the superfine glass wool in the process, a part of sound energy is rubbed in pores of the superfine glass wool to be converted into heat energy to be dissipated, resistive noise elimination is carried out, and the silicone heat-conducting glue uniformly coated on the contact surface of the U-shaped partition plates 4 and the shell 5 can dissipate the heat in the shell 5 as soon as possible; finally, the airflow flows through the small holes on the smoke exhaust pipe 6, and then is subjected to reactive noise elimination again and then is discharged out of the silencer.

The silencer internal silencing structure of the invention has no welding points with the upper and lower surfaces of the shell, and the smoke inlet and the smoke outlet pipes are only welded on the side surface of the shell with better rigidity, so that the upper and lower surfaces of the shell with poorer rigidity are not drawn by the internal silencing structure when the shell is expanded with heat and contracted with cold and impacted by smoke discharged by an engine, thereby avoiding the generation of cracks and solving the leakage problem of the common silencer.

The invention relates to a high-reliability plate-type silencer, which is particularly suitable for the fields of small silent generator sets and the like with higher requirements on the silencing performance and reliability.
