Abstract
A kind of catalyst converter, it comprises the housing extended vertically, the liner being contained in the carrier in described housing and being held between described housing and described carrier, the junction of described liner and described carrier forms junction plane, described carrier comprises the little second portion of first portion, the more described first portion of diameter and on airintake direction, is positioned at described junction plane upstream and shelters from the stopping surface of described junction plane, thus effectively can prevent the edge of gas attack liner.
Description
Technical field
The utility model relates to a kind of catalyst converter, belongs to automobile exhaust post-processing technology field.
Background technique
Traditional carrier is isodiametric vertically, and the carrier of this structure to be easy in automobile running play in housing, is subjected to displacement, thus have impact on purification efficiency.Once run into end cone in the process of play, be easy to carrier to rack.
Therefore, need to provide a kind of new scheme to solve the problems of the technologies described above.
Model utility content
The purpose of this utility model is to provide a kind of catalyst converter that effectively can prevent gas attack liner edge.
For achieving the above object, the utility model adopts following technological scheme: a kind of catalyst converter, it comprises the housing extended vertically, the liner being contained in the carrier in described housing and being held between described housing and described carrier, the junction of described liner and described carrier forms junction plane, and described carrier comprises the little second portion of first portion, the more described first portion of diameter and on airintake direction, is positioned at described junction plane upstream and shelters from the stopping surface of described junction plane.
As the technological scheme that the utility model improves further, described first portion is positioned at the upstream of described second portion on described airintake direction.
As the technological scheme that the utility model improves further, the cross section of described first portion and described second portion is T-shaped on the whole.
As the technological scheme that the utility model improves further, described first portion stretches out along described airintake direction from the centre of described second portion.
As the technological scheme that the utility model improves further, described second portion extends beyond described liner.
As the technological scheme that the utility model improves further, described junction plane axially extends along described, and described stopping surface extends along perpendicular to described axial vertical direction.
Compared to prior art, the utility model makes the stopping surface of described step on airintake direction, be positioned at described junction plane upstream and shelter from described junction plane, thus effectively can prevent the edge of gas attack liner.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the utility model catalyst converter.
Embodiment
Shown in please refer to the drawing 1, the utility model discloses a kind of catalyst converter 100, in automobile exhaust reprocessing.Described catalyst converter 100 comprises the housing 1 extended vertically, the liner 3 being contained in the carrier 2 in described housing 1 and being held between described housing 1 and described carrier 2.Described liner 3 forms junction plane 31 with the junction of described carrier 2.Described carrier 2 comprises the little second portion 22 of first portion 21 and the more described first portion of diameter 21, to form step 23 in described first portion 21 with the intersection of described second portion 22.Described step 23 is included in (direction of arrow on the left of please refer to the drawing 1) on airintake direction and is positioned at described junction plane 31 upstream and shelters from the stopping surface 231 of described junction plane 31.Described junction plane 31 axially extends along described, and described stopping surface 231 extends along perpendicular to described axial vertical direction.
Described first portion 21 is positioned at the upstream of described second portion 22 on described airintake direction.
Described first portion 21 is T-shaped on the whole with the cross section of described second portion 22.
Described first portion 21 stretches out along described airintake direction from the centre of described second portion 22, and described second portion 22 extends beyond described liner 3.
Because described junction plane 31 place may exist the risk of inefficacy, if namely sealing not, the waste gas of non-reduction-oxidation may directly overflow in this junction plane 31 place, thus affects purification efficiency.Carrier 2 is divided into the different two-part of diameter by catalyst converter 100 of the present utility model, and this design can play the effect of protective lining edge (i.e. junction plane 31) well, and can stop carrier 2 play in housing 1.
Compared with prior art, the utility model has the following advantages:
One, anti-liner corrosion: traditional carrier structure is easy to cause liner inlet end edge corrosion, in order to reduce corrosion, often adopts some Computer Aided Designs, so both adds the durability that cost also have impact on whole system.
Two, carrier play is prevented: carrier structure design of the present utility model, can be good at preventing the play of carrier in housing in the middle of automobile running.
In addition, the technological scheme of above embodiment only for illustration of the utility model and described by unrestricted the utility model, understanding of this description should based on person of ordinary skill in the field, although this specification has been described in detail the utility model with reference to the above embodiments, but, those of ordinary skill in the art is to be understood that, person of ordinary skill in the field still can modify to the utility model or equivalent replacement, and all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in right of the present utility model.
