Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one.
As shown in Figure 1, 2.
The removable Catalytic Converter of a kind of silencing apparatus, comprise catalyst carrier 1 (can adopt the honeycomb metal catalyst), catalyst carrier 1 clamps and is positioned in the connecting sleeve 4, connecting sleeve 4 is made up of the left connecting sleeve 2 and the right connecting sleeve 3 that connect by thread seal, one end of left side connecting sleeve 2 links to each other with Motor Vehicle expansion tube 6 welded seals (also can adopt thread seal to be connected), the other end of left side connecting sleeve 2 links to each other by thread seal with an end of right connecting sleeve 3, and the other end of right connecting sleeve 3 links to each other with motor-driven front bar 5 welded seals (also can adopt thread seal to link to each other).During concrete enforcement, it is removable being tightly connected that connecting sleeve 4 itself, connecting sleeve 4 have a place with Motor Vehicle expansion tube 6 joints, connecting sleeve 4 at least with motor-driven front bar 5 joints, so that in the connecting sleeve 4 of after electroplating catalyst carrier 1 being packed into.Below with 4 of connecting sleeves as removable connection, all the other are further described for welded seal is connected to example.
As shown in Figure 1, the connecting sleeve 4 of present embodiment is made up of left connecting sleeve 2 and right connecting sleeve 3, the two is connected by closely cooperating of internal and external threads, two ends of the inner chamber of the connecting sleeve of forming at left connecting sleeve 2 and right connecting sleeve 34 respectively are provided with a conical surface, and two ends of catalyst carrier 1 are located (also can catalyst carrier 1 be positioned in the connecting sleeve 4 by positioning step) by contacting with conical surface.Catalyst carrier 1 is provided with and left connecting sleeve contacted boss of 2 inner chamber conical surfaces or flange 7 with respect to an end of Motor Vehicle expansion tube 6, this boss or flange 7 can reduce the area of contact of catalyst carrier 1 and connecting sleeve 4, reduce the heat output of catalyst carrier 1, prolong the life-span of connecting sleeve 4 surface electrical coating to connecting sleeve 4.This boss or flange 7 also can save during concrete enforcement.
Left connecting sleeve 2 adopts plug-in type to be weldingly connected (as shown in Figure 1, 2) with Motor Vehicle expansion tube 6 in the present embodiment, and right connecting sleeve 3 also adopts be weldingly connected (as Fig. 1,2) with motor-driven front bar 5.Certainly, also can connect when specifically implementing, as long as connect, seal reliably by screw thread or alternate manner.
By Fig. 1,2 can find out, when not adopting the connecting sleeve 4 of present embodiment, removable section is not detachable structure, and adopt will be removable the connection between the left end of connecting sleeve 4 and the Motor Vehicle expansion tube 6, or adopt when being removable the connection between the right-hand member of connecting sleeve 4 and the motor-driven front bar 5, owing to be subjected to the restriction of motor vehicle exhaust size, the external diameter of catalyst carrier 1 is less, can not do to such an extent that the external diameter of the catalyst carrier 1 of picture shown in the present embodiment can be greater than the external diameter of motor vehicle exhaust, thereby the purifying effect of this detachable connection (seeing embodiment two for details) is compared weaker with present embodiment.
