Abstract
A round dissipative silencing and gas exhaust device is composed of a gas outlet pipe (1), a net plate (2), a net pipe (3), sound absorption materials (4), a gas inlet pipe (5) and a silencer body (7), wherein the gas outlet pipe (1) is arranged at one end of the annular silencer body (7), the gas inlet pipe (5) is arranged at the other end of the annular silencer body (7), the gas inlet pipe (5) is an elbow with an angle, one end of the gas inlet pipe (5) is connected with an exhaust port of an engine, and the other end of the gas inlet pipe (5) is connected with the gas outlet pipe (1) through the net plate (2). The round dissipative silencing and gas exhaust device is characterized in that a plurality of sets of dissipation holes (6) are formed in the net pipe (3), and the net pipe (3) is surrounded by the sound absorption materials. According to the round dissipative silencing and gas exhaust device, noise of the engine is propagated along a pipeline in the net pipe through the four sets of dissipation holes, is dispersed into the rock wool sound absorption materials and then is absorbed, part of sound energy is converted into heat energy through friction and the effect of adhesive tape so as to be dissipated, and the noise reduction and elimination effect of greatly reducing medium-and-high-frequency noise in the silencer body is achieved.
Description
Technical field
The utility model relates to the exhaust noise silencing facility of heavy duty equipment, especially about a kind of resistive muffling and exhausting device of circle.
Background technique
China recent years rapid economic development, is accompanied by economic rapid development, and country is also in newly-built Infrastructure energetically.From Qinghai-Tibet Railway to the Yangtze River Gorges, from the south water to north to transfering natural gas from the west to the east.None is not large-scale, a to strike the world with amazement engineering.Yet in these large construction projects, we can see the figure of the heavy machineries such as hoist, loader, grader, road roller, this is also indicating that China's heavy machinery obtained great development, along with the change of construction project is large, for heavy machinery industry be opportunity be also once to challenge simultaneously, the hoist of originally little tonnage can not meet the demand of production, must produce the needs that larger heavy machinery could meet market, because the engine power of large-scale engineering machinery is large, caused noise large, the problem such as exhaust pollution is serious.Muffling and exhausting device is exactly mainly to address these problems, and existing this series products exists that noise reduction is not up to standard, motor is because exhaust does not freely produce power loss, baffler barrel temperature is crossed the problems such as high mostly.
Summary of the invention
For above problem, the purpose of this utility model is to provide a kind of resistive muffling and exhausting device of circle, be to utilize two ends to have the cylindrical configuration of nose circle lid, internal structure adopts damped type, can weaken greatly the medium, high frequency noise effects problem that motor produces in the process of work.We,, at the inner absorbing exotic material of filling of this muffling and exhausting device, make this muffling and exhausting device in noise reduction, also greatly reduce the temperature of baffler outer wall simultaneously.
The technical solution of the utility model is achieved in the following ways: a kind of resistive muffling and exhausting device of circle, by steam outlet pipe, web plate, webmaster, sound-absorbing material, suction tude and baffler body, formed, one end of ring-type baffler body is provided with steam outlet pipe, the other end is provided with suction tude, suction tude is the bend pipe with angle, suction tude one end is connected with the relief opening of motor, the other end is connected with steam outlet pipe by web plate, it is characterized in that: in described webmaster, be provided with the loose hole of multicomponent, the surrounding of webmaster is surrounded by sound-absorbing material.
Described dispersion is to be longitudinally made as three groups, to be radially made as one group along baffler body.
Described sound-absorbing material is the rock wool of absorbing exotic material.
The utility model structure, the noise of motor is distributed in rock wool sound-absorbing material and is absorbed along the pipe transmmision in webmaster by four groups of interior dispersion hole, and when noise is propagated along silencing apparatus pipeline, sound wave just " dispersion " arrives in the sound-absorbing material of porous.Because friction and adhesive tape effect change part acoustic energy into thermal energy consumption and dissipate, soundproof effect falls in the medium, high frequency that reduces greatly baffler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By Fig. 1, known, a kind of resistive muffling and exhausting device of circle, by steam outlet pipe 1, web plate 2, webmaster 3, rock wool sound-absorbing material 4,5 suction tude and baffler body 7, formed, one end of ring-type baffler body 7 is provided with steam outlet pipe 1, and the other end is provided with suction tude 5, and suction tude 5 is the bend pipes with angle, the exhaust of suction tude 5 one end motors connects, the other end is connected with steam outlet pipe 1 by web plate 2, is provided with loose 6 holes of multicomponent in described webmaster 3, and the surrounding of suction tude 5 is surrounded by rock wool sound-absorbing material.Described dispersion 6 is to be longitudinally three groups, to be radially one group along baffler body 7.
Claims (3)
1. a circular resistive muffling and exhausting device, by steam outlet pipe (1), web plate (2), webmaster (3), sound-absorbing material (4), suction tude (5) and baffler body (7) form, one end of ring-type baffler body (7) is provided with steam outlet pipe (1), the other end is provided with suction tude (5), suction tude (5) is the bend pipe with angle, suction tude (5) one end is connected with the relief opening of motor, the other end is connected with steam outlet pipe (1) by web plate (2), it is characterized in that: in described webmaster (3), be provided with the loose hole (6) of multicomponent, the surrounding of webmaster (3) is surrounded by sound-absorbing material.
