Abstract
The invention discloses a silencer, in particular to an exhaust silencer for reducing the noise generated by air flows, which comprises an exhaust pipe for exhausting of a motor. A sealing board is arranged on the end portion of the exhaust pipe, the tail portion of the exhaust pipe is wrapped in a sealed container which is fixedly connected onto the exhaust pipe, and the tail portion of the container is provided with a gas outlet pipe. The exhaust silencer is characterized in that a plurality of ventilating through holes are arranged on the exhaust pipe in the container, and silencing sheets arranged on the tail portion of the exhaust pipe and on the inner wall of the container are further arranged in the container. The exhaust silencer changes the structure of a traditional silencer, thereby overcoming the defect that dust can accumulate on a traditional silencer, ensuring the silencing effect of the silencer, prolonging service life of the silencer and maintenance time of the silencer at the same time and lowering maintenance cost.
Description
Technical field
The present invention relates to a kind of silencer, particularly a kind of muffler that is used to reduce the sound that air flow produces.
Background technique
Motor corporation is provided with silencing apparatus in order to alleviate the exhaust sound from motor in the exhaust passageway of motor.Silencing apparatus forms a chamber volume at the outlet pipe of exhaust passageway at outer circumferential side, fills the sound absorbing material that is formed by glass fibre or Foamex etc. in the chamber volume, through this structure, reduces in the silencing apparatus by the sound that flows through the air generation that exhaust passes through.
Because there is partial combustion in motor; Contain solid particle in the gas of its discharge; Deposit on glass fibre that solid particle is filled in silencing apparatus easily or the Foamex; Use after a period of time when solid particle to deposit to a certain amount of the time, influenced the work of silencing apparatus, made improvement so the present invention is directed to the deficiency of existing technology.
Summary of the invention
The present invention is directed to the deficiency of existing technology, designed a kind of muffler that adopts the chip noise-reducing structure, can overcome the solid particle that long-time use causes and pile up influence, be convenient to maintenance, reduced maintenance cost exhaust silencer to the silencing apparatus effect.
The present invention realizes through following technological scheme:
Exhaust silencer comprises the outlet pipe that supplies engine exhaust, and the end of outlet pipe is provided with sealing plate; The afterbody of described outlet pipe is wrapped in the container of a sealing, and described container is fixedly connected on the outlet pipe, and the afterbody of container is provided with steam outlet pipe; It is characterized in that: the described outlet pipe that is positioned at container is provided with several noise elimination through holes, also is provided with the anechoic sheet that is connected outlet pipe afterbody and container inner wall in the described container, several noise elimination through holes of setting; Can reduce the flow velocity of the gas of motor discharge; When air communication was crossed the bloop of setting, bloop can further reduce the speed of air-flow, had reduced the flow velocity of discharging the gas of silencing apparatus; The bloop that adopts in addition is not that the muffler material that adopts is directly filled; Reduce the deposition of solid particle on muffler material, guaranteed the noise elimination effect of silencing apparatus, prolonged the working life of silencing apparatus.
The set inside of described steam outlet pipe has sound absorbing material.
Described anechoic sheet comprises a support plate, and a side layering of support plate is provided with multilayer noise reduction sheet material, and the support plate between the adjacent noise reduction sheet material is provided with sound hole.
The upper surface and the lower surface of described noise reduction sheet material are provided with muffler material.
The present invention has changed the structure of conventional muffler, has overcome the defective of traditional easy dust stratification of silencing apparatus, has guaranteed the noise elimination effect of silencing apparatus, has prolonged the working life of silencing apparatus, has prolonged the maintenance time of silencing apparatus simultaneously, has reduced the expense of safeguarding.
Description of drawings
Fig. 1 is the structural representation of exhaust silencer,
1 is outlet pipe among the figure, and 2 is sealing plate, and 3 is container, and 4 is steam outlet pipe, and 5 are the noise elimination through hole, and 6 is anechoic sheet, and 7 is support plate, and 8 are the noise reduction sheet material, and 9 is sound hole.
Embodiment
Below in conjunction with accompanying drawing the present invention is further specified:
Exhaust silencer as shown in Figure 1 comprises the outlet pipe 1 that supplies engine exhaust, and the end of outlet pipe 1 is provided with sealing plate 2; The afterbody of described outlet pipe 1 is wrapped in the container 3 of a sealing, and described container 3 is fixedly connected on the outlet pipe, and the afterbody of container 3 is provided with steam outlet pipe 4; The described outlet pipe 1 that is positioned at container is provided with several noise elimination through holes 5, also is provided with the anechoic sheet 6 that is connected outlet pipe 1 afterbody and container 3 inwalls in the described container 3, several noise elimination through holes 5 of setting; Can reduce the flow velocity of the gas of motor discharge; When air communication was crossed the bloop 6 of setting, bloop 6 can further reduce the speed of air-flow, had reduced the flow velocity of discharging the gas of silencing apparatus; The bloop that adopts in addition is not that the muffler material that adopts is directly filled; Reduce the deposition of solid particle on muffler material, guaranteed the noise elimination effect of silencing apparatus, prolonged the working life of silencing apparatus.
The set inside of described steam outlet pipe 4 has sound absorbing material, and the sound absorbing material of setting can further absorb the energy of air-flow, the noise when reducing the air-flow outflow.
Described anechoic sheet comprises a support plate 7; One side layering of support plate 7 is provided with multilayer noise reduction sheet material 8, and the support plate between the adjacent noise reduction sheet material 8 is provided with sound hole 9, here the structure of anechoic sheet is described; The sound hole worker air communication mistake that is provided with; Air communication is out-of-date, and the noise reduction sheet material weakens flowed energy, the noise when reducing the air-flow discharge.
The upper surface and the lower surface of described noise reduction sheet material are provided with muffler material.
The present invention has changed the structure of conventional muffler, has erasure effect preferably, has overcome the defective of traditional easy dust stratification of silencing apparatus; Guaranteed the noise elimination effect of silencing apparatus; Prolong the working life of silencing apparatus, prolonged the maintenance time of silencing apparatus simultaneously, reduced the expense of safeguarding.
