Description
Technical field
The present invention relates to vehicle exhaust process field, the purifier cavity body structure of specifically processing for vehicle exhaust.
Background technique
vehicle exhaust exceeds standard defective, is because the fuel oil in engine can not perfect combustion, causes carbon distribution to produce, and piles up, and the direct discharge of gas can contaminated air.In the automotive engineering development of past many decades, automobile factory has used many different modes to reduce exhaust emission, such as exhaust cycle, the recovery of fuel tank oil gas and engine electronic control system etc., these mode effects are not good, and a kind of exhaust purifier, also make Catalytic Converter but can bring into play effective effect aspect control exhaust emission pollution, it can reduce the discharge of carbon monoxide, black smoke and other toxic gas.At present, purifier is communicated with the relief opening of cylinder by outlet pipe, the whole cavity of purifier is to be generally directly weldingly fixed on car body, this gives maintenance, the maintenance in later stage very large constant, also there is in addition the symbolic fixing mode that adopts,, by being connected and fixed of the outlet pipe at purifier two ends, purifier cavity is simply fixed, this mode is not considered the stressed and center of gravity of purifier cavity, and this all may bring great impact to the tightness of purifier cavity and working life.
Summary of the invention
The object of the present invention is to provide the purifier cavity body structure of processing for vehicle exhaust, solved current purifier cavity and lacked comparatively firm fixing, do not take into full account the rational problem that is subject to force direction and means of fixation of purifier cavity.
The present invention for achieving the above object, realize by the following technical solutions: the purifier cavity body structure of processing for vehicle exhaust, comprise cavity and be separately fixed at the air inlet flange disks at cavity two ends and the flange plate of giving vent to anger, it is conical that the two ends of cavity are, described air inlet flange disks is provided with two the first connecting sheets, two the first connecting sheets lay respectively at the both sides of cavity and are symmetric, and two the first connecting sheets equate with the angle that air inlet flange disks place plane forms with the angle of air inlet flange disks place plane formation and the element of cone at cavity two ends;
Described cavity is provided with two the second connecting sheets, two the second connecting sheets lay respectively at the both sides of cavity, described the second connecting sheet comprises L-shaped vertical portion and horizontal component, and the vertical portion of the second connecting sheet is vertical with cavity, and horizontal component is parallel with the center line of cavity;
The plane at the plane at described two the first connecting sheet places and two the second connecting sheet places is same plane, on described two the first connecting sheets and two the second connecting sheets, is equipped with through hole.
Further, as preferred version, the angle that described the first connecting sheet becomes with air inlet flange disks is 30 ~ 45 degree.
Further, as preferred version, the length of described the first connecting sheet is 3 ~ 4cm.
Further, as preferred version, the length of described the second connecting sheet vertical portion is 2 ~ 3cm, and the length of horizontal component is 3 ~ 4cm.
Further, as preferred version, described the second connecting sheet is arranged on the vertical bisector of cavity 1 with the right side.
The present invention compared with prior art, have the following advantages and beneficial effect: the present invention has adopted the first connecting sheet and the second connecting sheet effectively to fix purifier cavity, the angle that the first connecting sheet forms with air inlet flange disks place plane and the element of cone at cavity two ends equate with the angle that air inlet flange disks place plane forms, thereby what make the first connecting sheet is subject to force direction consistent with the airintake direction of waste gas as much as possible, make the fixing more effective of the first connecting sheet; The second connecting sheet adopts L shaped structure, when the center of gravity of whole cavity is fixing, the horizontal component of the second connecting sheet is just consistent with airflow direction, has guaranteed rationality and stability that cavity is fixing, thereby is conducive to improve tightness and the working life of purifier cavity.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
As shown in Figure 1, the purifier cavity body structure of processing for vehicle exhaust described in the present embodiment, comprise cavity 1 and be separately fixed at the air inlet flange disks 2 at cavity 1 two ends and the flange plate 3 of giving vent to anger, it is conical that the two ends of cavity 1 are, described air inlet flange disks 2 is provided with two the first connecting sheets 4, two the first connecting sheets 4 lay respectively at the both sides of cavity 1 and are symmetric, two the first connecting sheets 4 equate with the angle that air inlet flange disks 2 place planes form with air inlet flange disks 2 angles of place planes formation and the element of cone at cavity 1 two ends, guaranteed like this first connecting sheet 4 be subject to force direction and fixed-direction basically identical, because the two ends of cavity 1 are taper, waste gas is just consistent with the fixed-direction of the second connecting sheet 4 to the souring force direction of cavity 1 inwall, thereby effectively played fixation.
The cavity 1 of the present embodiment is provided with two the second connecting sheets 5, two the second connecting sheets 5 lay respectively at the both sides of cavity 1, the second connecting sheet 5 comprises L-shaped vertical portion and horizontal component, and the vertical portion of the second connecting sheet 5 is vertical with cavity 1, horizontal component is parallel with the center line of cavity 1, vertical portion plays the effect of the whole cavity 1 that stretches, horizontal component can be tackled the souring of air-flow, thereby realized in correct direction reasonably, fix, make purifier cavity fixing more firm.
