Accompanying drawing in type embodiment, is clearly and completely described, it is clear that retouched to the technical scheme in this utility model embodiment
The embodiment stated is a part of embodiment of the present utility model, rather than the embodiment of whole.Based on the reality in this utility model
Apply example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made, all
Belong to the scope of this utility model protection.
This utility model is described for convenience, defines waste gas along direction flowing from front to back, each technical characteristic
Front and back position relation be the flow direction relative to waste gas being defined.
Facilitate description for convenience, be in the following description referred to as in the blender that a kind of surface can avoid the formation of crystallization
Blender.
As shown in Figure 1 to Figure 3, blender 5 includes blender frame 1 and some vane pieces 2, and blender frame 1 is in annular,
The extension track 21 of each vane piece is in respectively circular arc, defines the extension track of vane piece to extend track, extends track 21
In the tangent line and the diameter parallel of the inner chamber of blender frame 1 of front end, respectively extend the front end of track 21 positioned at the same of blender frame
In individual cross section, the angle of axis of the tangent line of track 21 and the inner chamber of blender frame 1 is extended along direction from front to back gradually
Increase.It is vane section to define figure of the vane piece in any one section perpendicular with the tangent line for extending track 21, is revolved
Leaf section is in arc-shaped structure.The vane section that definition is located in the cross section for extending the blender frame that the front end of track 21 is located is
Front end vane section 22；The one end in front end vane section 22 is connected to the circle centre position of the cross section of blender frame 1, each front end vane
The other end of section 22 is connected on the inner ring of blender frame 1.In same front end vane section, define front end vane and cut
The side that the center of circle in face is located is the inner side in front end vane section, and opposite side is the outside in front end vane section.Each front end vane
Section is uniformly distributed along the circumferencial direction of blender frame；Between the adjacent front end vane section of any two, positioned at previous
The inner side in front end vane section is arranged towards the outside in the front end vane section for being located at latter.Positioned at the same of same vane piece
In individual vane section, the center of circle in the center of circle and vane section that extend track 21 is located at the same side for extending track 21.
As depicted in figs. 1 and 2, the cross section that definition is located at the blender frame for extending the front end of track 21 place is blender frame
Front elevational sectional, projection of the vane piece in blender frame front elevational sectional include the contour line 24 of first round profile 23 and second, first
The contour line 24 of contour line 23 and second is in respectively circular arc, and the contour line 24 of first round profile 23 and second constitutes " S " type structure.
As shown in Figures 1 to 5, when engine exhaust gas is processed using this utility model, by blender 5 according in the past
Direction to after is installed in intermediate exhaust pipe 4, and as shown in Figure 4 and Figure 5, intermediate exhaust pipe 4 is in place for the installation direction of blender 5
Nozzle 41 is provided with the position of the front side of blender 5, nozzle is used to spray reducing agent to the direction of blender 5, intermediate exhaust
The front end of pipe 4 connects with front exhaust pipe 3, and the rear end of intermediate exhaust pipe 4 connects with heel row trachea 6, and the premenstrual exhaustor 3 of waste gas is flowed into
Intermediate exhaust pipe 4, the structure of blender 5 both can ensure that to give up and uniformly mix with reducing agent, also can guarantee that after a long time use
It is not in the problem of crystallization on vane piece.When reducing agent flows to blender along direction from front to back, vane section
The side of the vane piece 23 and reducing agent spraying that is located of the center of circle and waste gas collide, the mixture of reducing agent and waste gas is being flowed through
When blender, mixture produces eddy flow in the presence of each vane piece, and eddy flow can promote reducing agent and waste gas uniform
Mixing.Meanwhile, extending the center of circle of track can avoid in rotation with the center of circle in vane section positioned at the structure of the homonymy for extending track
Crystallization is formed on blade, so as to ensure the cleannes on the surface of vane piece, it is ensured that this utility model continues efficient work.Due to
It is in circular arc to extend track 21, and vane section is also in circular arc, even if so reducing agent spraying long-time is touched with vane piece
Hit and droplet is formed on vane piece, droplet also can subsequently be given up along the tangential direction of the structure of circular arc from vane piece
Gas is washed away, and crystallization is also not easily formed on vane piece, so as to ensure the long-time efficiency operation of blender.
