Description
Technical field
The utility model relates to a kind of motor vehicle components, particularly relates to a kind of SCR silencing apparatus of automobile-use.
Background technique
In order to improve the utilization ratio of fuel oil, reducing the content of pollutant in vehicle exhaust, reducing vehicle exhaust to the injury of environment, country is about to implement state IV Abgasgesetz.In order to reach state IV emission standard, just must use emission aftertreatment technology, SCR technology is exactly the one in post-processing technology.But adopt outlet pipe most boundary dimension precision of SCR technology not high at present, make troubles to follow-up assembling and affect appearance.
Model utility content
The utility model is for the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, and boundary dimension is accurate, is conducive to follow-up assembling and appearance, and the SCR silencing apparatus of the high automobile-use of intensity.
To achieve these goals, the utility model provides a kind of SCR silencing apparatus of automobile-use, comprise cylindrical shell, described inner barrel is welded with inner assembly, described inner assembly comprises two cylindric SCR ceramic monoliths and cylindrical case, vermiculite liner is provided with, described shell two ends reducing between described ceramic monolith and described shell; Described inner assembly two ends are welded with circular connector, described link and described barrel soldering, and described link is provided with through hole; Described cylindrical shell two ends are provided with end cap, and the end cap of described cylindrical shell one end is provided with suction tude and outlet pipe, is connected with tubaeform air flue between described outlet pipe and described shell; Described suction tude side is provided with urea nozzle seat, and described exhaust pipe side face is provided with nitrogen oxide sensor seat, and described suction tude and suction tude end are provided with flange; The end cap of the described cylindrical shell the other end is provided with the support for installing thermal baffle.
Wherein, described link is by the ring channel structures of steel plate punched.
Described suction tude, between outlet pipe and described end cap, be provided with stiffening rib.
Described suction tude, outlet pipe and described flanged ends are provided with flange.
Described cylindrical shell and shell are that 06Cr19Ni10 (SUS304) corrosion resistant plate makes.
During production, first with vermiculite liner parcel ceramic monolith, then to shell shaping ceramic monolith is pressed into shell, the reducing of shell two ends is formed inner assembly; On mould, shell is welded with link afterwards; Then inner assembly pressed fit into cylindrical shell with link and weld; Afterwards, weld tubaeform air flue to weld with outer casing end; Retell end cap to weld with cylindrical shell, tubaeform air flue; Finally weld suction tude, steam outlet pipe, flange, support.
The beneficial effect of this programme can be learnt according to describing of such scheme, and structure is simple, reasonable in design, and boundary dimension is accurate, be conducive to follow-up assembling and appearance, and intensity is high.By ceramic monolith be the inner assembly filling type of main body be encapsulated into inner barrel, ensure that overall apparent size precision, and improve the structural strength around ceramic monolith.Suction tude and steam outlet pipe end arrange flange, not only ensure that the dimensional accuracy of suction tude and steam outlet pipe, and end strengthening is avoided and distortion during flange welding, also effectively prevent the weld cracking phenomenon shaking and cause.The reducing process of shell two ends can prevent the play of ceramic monolith.Link is by the ring channel structures of steel plate punched, is conducive to the size in adjustment ring and outside ring on grinding tool.Be provided with dividing plate between inner assembly and suction tude one end, the intensity improving cylindrical shell while inner assembly and suction tude have sufficient space can be ensured again.Cylindrical shell and shell are that 06Cr19Ni10 (SUS304) corrosion resistant plate makes, and well can solve the etching problem of urea to silencer cylinder, and silencing apparatus are without the need to carrying out surface treatment.
