Abstract
The utility model relates to the technical field of auto parts and particularly discloses a gas exhaust pipe. The gas exhaust pipe comprises a body and a filter. One end of the body is in the shape of a cone, the other end of the body is columnar, and the outer surface of the body is in smooth transition from the columnar end to the cone end; the inner wall of the body and the outer wall of the body are provided with zinc coatings respectively, and therefore anti-corrosion ability of the gas exhaust pipe is guaranteed. The body is further provided with a through hole communicated with the two ends, and the filter is arranged in the through hole. A particle filter screen, an intermediate-efficiency filter screen and an efficient filter screen are sequentially arranged in the filter, one supporting screen is arranged between the particle filter screen and the intermediate-efficiency filter screen, another supporting screen is arranged between the intermediate-efficiency filter screen and the efficient filter screen, the thickness of the particle filter screen, the thickness of the intermediate-efficiency filter screen and the thickness of the efficient filter screen respectively range from 2 mm to 3 mm, and the thickness of each supporting screen is 1 mm. Small particles and dust in tail gas of a car are filtered out by the filter in a layered filtering mode, and therefore the phenomenon that car tail gas containing small particles and dust is discharged to the atmosphere by the car is avoided.
Description
Technical field
The utility model relates to the accessory technical field of automobile, is specifically related to a kind of outlet pipe for automobile.
Background technique
Along with the development of human society, the quantity of the needed automobile of mankind's activity is also more and more, and the waste gas that therefore automobile is discharged is also more and more, makes the pollution of air quality day by day serious; In order to alleviate the situation of pollution of air quality now, therefore the present outlet pipe for automobile is all provided with filter layer, so but filter layer is now all monolayer of particles filter layer, can only filter big dust particle, granule dust (as PM2.5 etc.) can not be filtered, the situation of the pollution of air quality now can not be alleviated.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of outlet pipe, its object: have corrosion resistance, can filter granule dust.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of outlet pipe, comprises main body and filter, and one end of main body is conical, and the other end of main body is cylindrical, and the appearance of main body to conical end, is equipped with zinc coat on the inner and outer wall of described main body by cylindrical end rounding off;
Main body is also provided with the through hole that connects two ends, and filter is arranged on the inside of through hole;
In described filter, be provided with successively particle filtering net, medium air filtration net and high efficiency pariculate air, between particle filtering net and medium air filtration net, be provided with supporting network, between medium air filtration net and high efficiency pariculate air, be also provided with supporting network;
The thickness of particle filtering net, medium air filtration net and high efficiency pariculate air is 2 millimeters to 3 millimeters, and the thickness of supporting network is 1 millimeter.
Preferably, the cross section of described through hole is circular.
By technique scheme, on the inner and outer wall of main body, be equipped with zinc coat, guarantee that this outlet pipe has corrosion resistance; Filter falls vehicle exhaust small particles dust filtration by layered filtration, effectively prevented automobile by the motor vehicle exhaust emission that contains granule dust in the middle of atmosphere.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of outlet pipe disclosed in the utility model;
Fig. 2 is that the master of a kind of outlet pipe disclosed in the utility model looks schematic diagram.
Numeral and the represented corresponding part title of letter in figure:
1. main body 11. zinc coat 12. through hole 21. particle filtering net 22. medium air filtration net 23. high efficiency pariculate air 24. supporting networks
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of outlet pipe, comprises main body 1 and filter, and one end of main body 1 is conical, and the other end of main body 1 is cylindrical, and the appearance of main body 1 to conical end, makes this outlet pipe be convenient to install by cylindrical end rounding off.
On the inner and outer wall of described main body 1, be equipped with zinc coat 11, zinc coat 11 has good corrosion resistance.
Main body 1 is also provided with the through hole 12 that connects two ends, the cross section of through hole 12 is circular, filter is arranged on the inside of through hole 12, in filter, be provided with successively particle filtering net 21, medium air filtration net 22 and high efficiency pariculate air 23, between particle filtering net 21 and medium air filtration net 22, be provided with supporting network 24, between medium air filtration net 22 and high efficiency pariculate air 23, be also provided with supporting network 24, supporting network 24 can firmly support particle filtering net 21, medium air filtration net 22 and high efficiency pariculate air 23.
Particle filtering net 21 falls oarse-grained dust filtration, and medium air filtration net 22 and high efficiency pariculate air 23 cooperatively interact and tiny dust filtration can be fallen, effectively prevented automobile by the motor vehicle exhaust emission that contains granule dust in the middle of atmosphere.
The thickness of particle filtering net 21, medium air filtration net 22 and high efficiency pariculate air 23 is 2.5 millimeters, guarantee the filtering effect of filter, the thickness of supporting network 24 is 1 millimeter, the integral thickness of filter is controlled in 20 millimeters, facilitate dismounting and the installation of filter, reduced the maintenance cost of this outlet pipe.
Be exactly more than a kind of structural feature and action effect of outlet pipe, its advantage: simple in structure, easy for installation; There is corrosion resistance, can filter granule dust.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
