Abstract
The utility model relates to a foamed aluminium automobile internal-combustion engine exhaust silencer which is wrapped by a columnar steel shell (1) and is internally provided with a foamed aluminium acoustic board liner (3); a silencer intake tube (4) is inserted into the other end of the silencer from one end of the silencer and passes through two layers of foamed aluminium silencing filter plates (7); a port of the silencer intake tube is provided with a foamed aluminium intake silencing filter cover (2); a silencer exhaust pipe (5) is inserted from the other end of the silencer and passes through the two layers of foamed aluminium silencing filter plates (7); an airflow inlet of the exhaust pipe is provided with a foamed aluminium exhaust silencing filter cover (8); the foamed aluminium silencing filter plates divide the interior of the silencer into three sections so as to form three relatively independent silencing cavities (6); and the foamed aluminium automobile internal-combustion engine exhaust silencer is formed by the structures.
Description
One, technical field: foamed aluminium car combustion engine exhaust silencer has adopted novel sound-absorbing material foamed aluminium, belong to the new material application, foamed aluminium automobile, exhaust silencer for internal-combustion engine are applicable to that all use the exhausting silencer of internal-combustion engine as the machinery of the large, medium and small automobile of power, steamer, generator etc., therefore also belong to and eliminate noise and field of noise control.
Two, background technique: traditional car combustion engine exhaust silencer is that the noise elimination structure that adopts steel plate to make a barrel shape is eliminated exhaust sound, itself does not absorb sound steel plate, but the good conductor of sound, in order to improve the noise elimination effect steel plate of the inner key position of silencing apparatus is made cellular, but stephanoporate steel plate is compared with new material foamed aluminium acoustic board, acoustically effective falls far short, the utility model is to adopt novel sound-absorbing material foamed aluminium to make the silencing apparatus of noise elimination structure again, and this silencing apparatus has dual noise elimination and filtration.Most in addition automobiles, exhaust silencer for internal-combustion engine all are lower than the working life of internal-combustion engine working life, use anaphase effect worse and worse, noise pollution to environment also can increase the weight of, the main cause that conventional muffler is damaged is the high temperature corrosion induced gas that internal-combustion engine is discharged, and foamed aluminium is consistent with the metallic aluminium physical property, corrosion-resistant, high temperature resistant, good heat conductivity, thereby can effectively prolong working life of silencing apparatus.
Three, summary of the invention: the utility model foamed aluminium car combustion engine exhaust silencer, wrap up by steel shell (1), in foamed aluminium acoustic board liner (3) is arranged, silencing apparatus suction tude (4) is inserted into the other end from an end of silencing apparatus, pass two layers of foam aluminium noise elimination filter plate (7), silencing apparatus suction tude port is equipped with foamed aluminium intake noise reduction filter cap (2), muffler tail pipe (5) is inserted by the other end of silencing apparatus, pass two layers of foam aluminium noise elimination filter plate (7), at the gas exhausting tube inflow entrance foamed aluminium exhausting silencer filter cap (8) is housed, foamed aluminium noise elimination filter plate (7) is being divided into three sections in the silencing apparatus.Form relatively independent three noise elimination cavitys (6).
Foamed aluminium car combustion engine exhaust silencer off-gas flows trend: enter through silencing apparatus suction tude (4) that------------------muffler tail pipe (5) enters atmosphere to noise elimination cavity (6)---exhausting silencer filter cap (8)---to foamed aluminium noise elimination filter plate (7) to noise elimination cavity (6) to foamed aluminium noise elimination filter plate (7) to noise elimination cavity (6) to foamed aluminium intake noise reduction filter cap (2).
Its principle of foamed aluminium car combustion engine exhaust silencer is that the waste gas that has the sharp pounding noise behind the combustion in IC engine enters silencing apparatus through silencing apparatus suction tude (4), noise is at first eliminated the noise for the first time by suction port foamed aluminium sound proof housing (2), eliminate the noise for the second time through noise elimination cavity (6), filter noise elimination for the third time through foamed aluminium noise elimination filter plate (7) near suction port foamed aluminium sound proof housing (2), waste gas enters two blocks of foamed aluminium noise elimination filter plates (7) and the common noise elimination cavity of forming of foamed aluminium acoustic board liner (3) is eliminated the noise for the 4th time, filter noise elimination the 5th time through foamed aluminium noise elimination filter plate (7) near relief opening foamed aluminium sound proof housing (8), eliminate the noise for the 6th time through silencing apparatus resonant cavity (6) resonance, the back is discharged by muffler tail pipe after relief opening foamed aluminium sound proof housing (8) is eliminated the noise for the 7th time, thereby reaches good exhausting silencer effect through above seven impedance complex noise elimination.
Four, description of drawings: Fig. 1 is the sectional drawing of foamed aluminium car combustion engine exhaust silencer, and foamed aluminium car combustion engine exhaust silencer is mainly by constituting with the bottom.
1, steel casing
2, foamed aluminium intake noise reduction filter cap
3, foamed aluminium sound absorption interior lining panel
4, silencing apparatus suction tude
5, muffler tail pipe
6, noise elimination cavity
7, foamed aluminium noise elimination filter plate
8, foamed aluminium exhausting silencer filter cap
Five, specific embodiments: making cross section with the 3mm steel plate is the ellipse garden of 150mm-250mm type, length is the oval column shell of 400mm, long to being welding, two ends are the flange seaming, the shell inwall adheres to the thick fine-crystal spume aluminium alloy acoustic board of 10mm, the two blocks of thick foamed aluminium noise elimination filter of 10mm plates (7) are being divided into three sections in the silencing apparatus, form relatively independent three noise elimination cavitys (6), the foamed aluminium noise elimination filter plate of close silencing apparatus suction tude end is in the lower openings away from suction port, the foamed aluminium noise elimination filter plate of close muffler tail pipe port is at the upper opening away from exhaust port, diameter 40mm silencing apparatus suction tude is inserted into the other end from an end of silencing apparatus and passes two layers of foam aluminium noise elimination filter plate, it is outer through 60mm length 100mm intake noise reduction filter cap that the suction port end is equipped with internal diameter 40mm, the other end that diameter 40mm muffler tail pipe is inserted by the silencing apparatus suction tude inserts, outside being equipped with internal diameter 40mm, the gas exhausting tube inflow entrance, promptly can be made into the foamed aluminium automobile by above specific embodiments through 60mm length 100mm exhausting silencer filter cap, exhaust silencer for internal-combustion engine.
