Abstract
The utility model relates to an automotive auxiliary accessory, in particular to a diesel vehicle muffler which comprises a muffler shell body, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are connected with the muffler shell body into a whole and are communicated with an inner cavity of the muffler shell body; and a plurality of air deflectors are arranged in the muffler shell body and are arranged in the muffler shell body in a staggered manner to form a muffling channel. The diesel vehicle muffler has the beneficial effects that the diesel vehicle muffler is simple in structure and has good noise elimination effect; and tail gas muffled by the diesel vehicle muffler satisfies the state environmental protection requirements, physical and psychological health of workers at the workplace are ensured and good production environment is created.
Description
Technical field
The utility model relates to a kind of automobile auxiliary accessories, is specifically related to a kind of diesel-oil vehicle silencing apparatus.
Background technique
The powerful diesel engine of oil field, the first-class use in ore deposit; It all can produce the noise up to 110 decibels, the noise pollution that it causes in work, running process; Worker, resident around not only making can not get having a rest for a long time, and severe impairment staff's physical and mental health.
Summary of the invention
To above-mentioned technical problem, the utility model provides a kind of and is installed on the Diesel Engine Exhaust Pipe, can when diesel engine turns round, reduce the diesel-oil vehicle silencing apparatus of its noise.
The technological scheme that realizes the utility model is following:
A kind of diesel-oil vehicle silencing apparatus; Comprise the noise elimination housing; And the suction tude, the steam outlet pipe that connect as one and be communicated with noise elimination housing inner chamber with the noise elimination housing, being provided with several wind deflectors in the said noise elimination housing, said wind deflector is crisscross arranged and in the noise elimination housing, forms a noise elimination passage.
Said wind deflector is provided with the wind-guiding inclined-plane, and the wind-guiding inclined-plane can lead to the tail gas that gets in the noise elimination housing, and tail gas is discharged in steam outlet pipe from the noise elimination passage.
Said wind deflector is provided with air-guiding hole.Air-guiding hole can alleviate the interior tail gas pressure of noise elimination housing and tail gas is produced certain noise elimination effect.
Said noise elimination housing outer wall is provided with cooling duct.The tail gas that goes out at diesel emission has higher temperature, through the setting of cooling duct, the temperature in the noise elimination housing is reduced.
Adopted such scheme, tail gas is guided by wind deflector after getting into the noise elimination housing, in the noise elimination passage, passes through, and prolongs its stroke, reduces noise, and the air-guiding hole on the wind deflector also can play certain effect that abates the noise in addition.The utility model is simple in structure, it is effective to abate the noise, and the tail gas through the utility model is eliminated the noise satisfies national requirements for environmental protection, has guaranteed work-yard staff's physical and mental health, has created good production environment.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1 is the noise elimination housing, and 2 is suction tude, and 3 is steam outlet pipe, and 4 is wind deflector, and 5 is the wind-guiding inclined-plane, and 6 is air-guiding hole, and 7 is cooling duct.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Referring to Fig. 1; A kind of diesel-oil vehicle silencing apparatus; Comprise noise elimination housing 1, and the suction tude 2, the steam outlet pipe 3 that connect as one and be communicated with noise elimination housing 1 inner chamber with noise elimination housing 1, suction tude one end has adpting flange; And suction tude being connected the tail gas exhaust port of DENG through this adpting flange, the tail gas that DENG is discharged can just go into to eliminate the noise in the housing; Be provided with seven wind deflectors 4 in the noise elimination housing 1, above three wind deflectors and four following wind deflectors are crisscross arranged and in the noise elimination housing, form a noise elimination passage.Wind deflector 4 is provided with wind-guiding inclined-plane 5, and the wind-guiding inclined-plane can lead to the tail gas that gets in the noise elimination housing, and tail gas is discharged in steam outlet pipe from the noise elimination passage.Wind deflector 4 is provided with air-guiding hole 6, and air-guiding hole can alleviate the tail gas pressure in the noise elimination housing and produce certain noise elimination effect.Noise elimination housing 1 outer wall is provided with cooling duct 7, through the setting of cooling duct, the temperature in the noise elimination housing is reduced, and plays the effect to the protection of noise elimination housing, prolongs the working life of silencing apparatus.
