Abstract

The invention discloses a small automotive silencer and compound corrosion prevention for the surfaces thereof. The small automotive silencer comprises a shell (1), a gas inlet tube (2), an exhaust tube (3) and a silencing chamber (4). The gas inlet tube (2) is manufactured at the left lower end of the shell (1), the exhaust tube (3) is manufactured at the right upper end of the shell (1), the silencing chamber (4) is an irregular gourd-shaped closed chamber, one end of the silencing chamber (4) is connected with the gas inlet tube (2), the other end of the silencing chamber (4) is connected with the exhaust tube (3), the silencing chamber (4) is filled with three-level novel sound absorption and noise reduction materials which comprise novel environment-friendly noise reduction materials with bamboo carbon fibers, melt-blow superfine single-component sound absorption fibers and melt-blow superfine double-component sound absorption fibers, and Dacromet coating, zinc impregnation and closing layer compound corrosion prevention treatment is carried out on the inner and outer surfaces of the gas inlet tube (2), the inner and outer surfaces of the exhaust tube (3) and the inner and outer surfaces of the silencing chamber (4). The small automotive silencer and the compound corrosion prevention have the advantages that the small automotive silencer is simple in structure and scientific in design and is made of the advanced materials, obvious sound absorption and silencing effects can be realized, the service life of the small automotive silencer can be obviously prolonged, and the maintenance cost can be greatly reduced.

Description

Compact car baffler and surface recombination thereof are anticorrosion
Technical field
The present invention relates to vehicle key component manufacturing technology field, be specifically related to a kind of compact car baffler and surface recombination thereof anticorrosion.
Background technique
Along with family's passenger car is universal, the especially increase day by day of urban taxi, the noise that vehicle traveling process sends, has become the arch-criminal who affects city peacefulness.Baffler is installed is and reduce one of effective measures of automobile running noise.
Current most of compact car baffler, adopts many many casees of dividing plate cell structures, although erasure effect is obvious, automobile engine to exhaust is formed to larger resistance, reduce motor effective output, and manufacture cost is high, and maintain and replace is loaded down with trivial details.The more important thing is, mobile muffler working environment is comparatively severe, hot soak condition, and a large amount of contact corrosion gas, need to bear larger active force, not only need structure reasonable in design, also need baffler itself to carry out surface peening preservative treatment, could extend mobile muffler working life, reduce maintenance cost.
Summary of the invention
In order to address the above problem, the invention provides a kind of compact car baffler and surface recombination thereof anticorrosion, not only simple in structure, design science, use material is advanced, sound-absorbing and erasure effect are obvious, and air intake-exhaust is unobstructed, engine exhaust resistance is little, output power is normal, the more important thing is: due to mobile muffler air inlet-outlet pipe and anechoic chamber inner and outer surface have been carried out, NEW TYPE OF COMPOSITE is anticorrosion, and mobile muffler can effectively be resisted the erosion of harmful gas under long term high temperature environment, be able to significant prolongation working life, thereby significantly reduce maintenance cost.
To achieve these goals, the present invention adopts technological scheme as follows:
A kind of compact car baffler and surface recombination thereof are anticorrosion, comprise housing, suction tude, outlet pipe, anechoic chamber.Described Inlet Manifold Design is produced on described housing lower-left end, and described Design of Exhaust Manifold is produced on described housing upper right side, and described anechoic chamber manufactures and designs for irregular calabash shaped airtight chamber, and its one end connects described suction tude, and the other end connects described outlet pipe.
As further optimization of the present invention, a kind of compact car baffler and surface recombination thereof are anticorrosion, be filled with bamboo-carbon fibre novel environment friendly acoustic damping materials, melt and spray ultra-fine one pack system acoutic fibre board and melt and spray three grades of sound-absorbing acoustic damping materials that ultra-fine double-component acoutic fibre board forms in described anechoic chamber.
Further optimization as invention, a kind of compact car baffler and surface recombination thereof are anticorrosion, the bamboo-carbon fibre novel environment friendly acoustic damping materials of filling in described anechoic chamber, melt and spray ultra-fine one pack system acoutic fibre board and melt and spray three grades of absorbing sound and lowering noise materials that ultra-fine double-component acoutic fibre board forms, can be for convenience detach, change and clean.
As the further optimization of invention, a kind of compact car baffler and surface recombination thereof are anticorrosion, and described suction tude, outlet pipe and anechoic chamber's inner and outer surface are all processed through Dacroment coating+zincizing+confined bed composite anti-corrosive.
The present invention is not only simple in structure, design science, use material is advanced, and sound-absorbing and erasure effect are obvious, and air intake-exhaust is unobstructed, engine exhaust resistance is little, output power is normal, the more important thing is: because mobile muffler air inlet-outlet pipe and anechoic chamber inner and outer surface have all carried out NEW TYPE OF COMPOSITE preservative treatment, mobile muffler can effectively be resisted the erosion of harmful gas under long term high temperature environment, be able to significant prolongation working life, thereby significantly reduce maintenance cost.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
In Fig. 1,1 is that housing, 2 is that suction tude, 3 is that outlet pipe, 4 is anechoic chamber.
embodiment:
Below in conjunction with Fig. 1, by specific embodiment, the present invention will be further described.
A kind of compact car baffler and surface recombination thereof are anticorrosion, comprise housing 1, suction tude 2, outlet pipe 3, anechoic chamber 4.Described suction tude 2 designs and produces at described housing 1 lower-left end, described outlet pipe 3 designs and produces at described housing 1 upper right side, described anechoic chamber 4 manufactures and designs for irregular calabash shaped airtight chamber, and its one end connects described suction tude 2, and the other end connects described outlet pipe 3.In described anechoic chamber 4, be filled with bamboo-carbon fibre novel environment friendly acoustic damping materials, melt and spray ultra-fine one pack system acoutic fibre board and melt and spray three grades of sound-absorbing acoustic damping materials that ultra-fine double-component acoutic fibre board forms.
As further optimization of the present invention, a kind of compact car baffler and surface recombination thereof are anticorrosion, the bamboo-carbon fibre novel environment friendly acoustic damping materials of described anechoic chamber 4 interior fillings, melt and spray ultra-fine one pack system acoutic fibre board and melt and spray three grades of sound-absorbing acoustic damping materials that ultra-fine double-component acoutic fibre board forms, can be for convenience detach, change and clean.
As the further optimization of invention, a kind of compact car baffler and surface recombination thereof are anticorrosion, and described suction tude 2, outlet pipe 3 and anechoic chamber's 4 inner and outer surface are all processed through Dacroment coating+zincizing+confined bed composite anti-corrosive.
