Abstract
The utility model relates to a silencer of a silenced diesel engine, which can be applied to a marine diesel engine. The silencer of the silenced diesel engine comprises a shell, an air inlet pipe and an air outlet pipe, wherein the shell is cylindrical; the air inlet pipe is arranged on the side surface of one edge of the shell; the air outlet pipe is arranged at the other end of the shell and is located on the same central axis with the shell; a 90-DEG angle is formed between the air inlet pipe and the air outlet pipe. The silencer is characterized by also comprising a sound absorption layer; the shell comprises an inner side plate, a supporting member and an outer side plate. By using the silencer, the shell is improved, and the vibration noise of the shell is effectively reduced; meanwhile, the silencer has the advantages of simple structure, good sound insulation and damping effects, long service life and the like.
Description
Technical field
The utility model relates to a kind of silencing type diesel engine silencer, can be applicable in marine ships diesel engine.
Background technique
The waste gas that traditional boat diesel engine is discharged in its working procedure can produce very noisy, most diesel engine is all provided with baffler, the effect of baffler is to absorb the very noisy that waste gas produces, to eliminate, to reduce the impact of Noise upon Environment, the kind of the baffler on market is a lot, but these bafflers are only in shape and install and have difference, and the structure of baffler itself and working principle do not change.
Model utility content
The purpose of this utility model is to overcome existing the problems referred to above in prior art, and a kind of reasonable in design is provided, the silencing type diesel engine silencer of convenience, energy-saving and environmental protection.
The utility model solves the problems of the technologies described above adopted technological scheme: this silencing type diesel engine silencer, include housing, suction tude and steam outlet pipe, described housing is cylinder-like body, described suction tude is located on housing side on one side, steam outlet pipe is located at the housing the other end, and with housing on same central axis, described suction tude and steam outlet pipe are mutually 90 degree angles, its feature is being, also include absorbent treatment, described housing includes side inner panel, supporting element and outer panel, described side inner panel and outer panel encapsulate the vibration damper plate of composition with interlayer mutually, interlayer between side inner panel and outer panel is sealed vacuum chamber, between side inner panel and outer panel, support by supporting element, described supporting element is the one supporting bar of turning back, it is turned back to join by head and the tail in some the support vertical bar substantially horizontals that are parallel to each other and forms, the described supporting bar of turning back is integral type structure, described absorbent treatment is located in housing.
As preferably, described supporting element is soft heat-resistant sound-insulation material.
As preferably, described soft heat-resistant sound-insulation material is soft rubber pad.
As preferably, described absorbent treatment is fire prevention ore deposit rock wool.
As preferably, the thickness of described side inner panel, supporting element and outer panel is different, and the thickness of outer panel is greater than the thickness of side inner panel, and the thickness that is respectively side inner panel is 1.2mm, and the thickness of supporting element is 0.8mm, and the thickness of outer panel is 1.5mm.
The beneficial effects of the utility model are: when this product reduces discarded noise by traditional approach, improve for housing itself, effectively reduce the vibration noise of housing, have simple in structure simultaneously, sound insulation good damping effect, the advantages such as long service life, double layer design can also effectively reduce thermal radiation for the impact of component around.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment one: referring to Fig. 1-5, this product includes housing 1, suction tude 2, steam outlet pipe 3 and absorbent treatment 4, housing 1 is cylinder-like body, suction tude 2 is located on housing 1 side on one side, steam outlet pipe 3 is located at housing 1 the other end, and with housing 1 on same central axis, suction tude 2 is mutually 90 degree angles with steam outlet pipe 3, the housing 1 of this product includes side inner panel 11, supporting element 12 and outer panel 13, side inner panel 11 and outer panel 13 mutually encapsulation form the vibration damper plate 5 with interlayer, interlayer between side inner panel 11 and outer panel 13 is sealed vacuum chamber 14, between side inner panel 11 and outer panel 13, support by supporting element 12, supporting element 12 is the one supporting bars of turning back, it is turned back to join by head and the tail in some the support vertical bar substantially horizontals that are parallel to each other and forms, the supporting bar of turning back of this product is integral type structure, absorbent treatment 4 is located in housing 1, absorbent treatment 4 is fire prevention ore deposit rock wool.
Supporting element 12 in the present embodiment is soft heat-resistant sound-insulation material, and specifically soft heat-resistant sound-insulation material is a kind of soft rubber pad.
Side inner panel 11, supporting element 12 in the present embodiment are different with the thickness of outer panel 13, and the thickness of outer panel 13 is greater than the thickness of side inner panel 11, and the thickness that is respectively side inner panel 11 is 1.2mm, and the thickness of supporting element 12 is 0.8mm, and the thickness of outer panel 13 is 1.5mm.
In actual using process, waste gas enters as in housing 1 by suction tude 2, the vibration damper plate 5 own damping sound insulation sandwich structurees that housing 1 adopts can effectively reduce vibrating noise, waste gas, through the further sound-absorbing of absorbent treatment 4, is then discharged from steam outlet pipe 3 simultaneously, finally completes noise reduction.
