Specific implementation mode
Fig. 1 is a kind of ammonia filter for engine exhaust post-processing, is made of head cover 1, filter tank 2 and filter core 3.
Head cover 1 and filter tank 2 connect, in the air-tightness inner cavity that filter core 3 is constituted after being connect with filter tank by head cover.Wherein
The upper end of filter core is connect with head cover inner cavity, and filter core upper end and the junction of head cover 1 are provided with sealing ring 4, and the lower end of filter core is solid
It is scheduled on the bottom surface of filter tank inner cavity.
In fig. 2, the port of head cover 1 is equipped with a circle wedge-shaped impression 102 downward, at port.The section of wedge-shaped impression is interior
Recessed splayed, and the two sides of wedge-shaped impression is inclined inclined-plane (Fig. 6).
In figure 3, the port of filter tank 2 is equipped with a circle wedge joint 201 upward, at port.Wedge joint is at the end of filter tank
It is stretched out upwards at mouthful, for the section shape of wedge joint similar to a upward arrow, inside and outside two sides is inclined slope surface (figure
7)。
In Figure 5, wedge joint 201 is adapted with the shape of wedge-shaped impression 101.When assembly, the wedge shape of filter tank port connects
Head is inserted into the cavity of head cover port wedge-shaped impression, and the slope surface on wedge joint two sides and the inclined-plane on wedge-shaped impression two sides mutually paste
Merge contact.
In Fig. 4, the upper end of filter core 3 is equipped with a groove 301 of the circle for installing sealing ring, there are one the bottom surface of filter core is set
Round bump 302, when assembly, which can just be embedded in the pit for being located at 2 inner chamber bottom surface of filter tank.
Head cover 1 and filter tank 2 are all made of the making of nonmetal heating plastic material, and Buddhist nun can be used in common nonmetal heating plastic material
Dragon plus glass fiber composite material or nylon add carbon-fiber composite material.In the present embodiment, filter tank and head cover, which have been selected, is specially
The nylon of PA66+GF30 adds glass fiber composite material, and this composite material can use friction in addition to having preferable thermoplastic property
Welding, while also there is good intensity.
In the present embodiment, head cover and filter tank are that the port of the two is welded to each other by the method for using spin friction.
Specific practice is first to assemble filter core 3 and head cover 1 and filter tank 2, then by the wedge shape of the wedge joint 201 and head cover of filter tank
Groove 102 is in contact, and then so that head cover 1 and filter tank 2 is rotated around common axis by spin friction welding machine, and to the upper of the two
Lower port junction axial pressure melts the material in self-contact face by heat caused by contact surface friction at the two port
Material, to achieve the purpose that wedge-shaped impression is welded to each other with wedge joint.
The ammonia filter of the present embodiment is in use, the exhaust gas of engine discharge enters from the inlet pipeline on head cover by pushing up
It covers in the inner cavity after being connect with filter tank, by being discharged again from the outlet conduit on head cover after filter element filtering.Due to head cover and filter tank
Connection welding is melted using frictional heat so that the inner cavity of filter has preferable air-tightness, and exhaust gas will not overflow from filter
Go out.And filter core is also to be tightly connected with head cover and filter tank so that exhaust gas can follow the prescribed course after filter element filtering again
Discharge.
The filter tank of the present embodiment ammonia filter and the nonmetal heating moulding material selected by head cover comply fully with current road
Vehicle environmental protection, light-weighted requirement, the wherein connection structure of wedge joint and wedge-shaped impression improve product company with welding design
The intensity and reliability of socket part position.
It should be understood that the filter tank and head cover of the present embodiment, although selected nonmetal heating moulding material is PA66+
GF30, but can also be in any other form thermoplastic material, such as PBT, PTFE, PA6 etc..
Above-described the utility model embodiment, does not constitute the restriction to scope of protection of the utility model.It is any
Modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in the utility model
