Detailed Description
The following detailed description of the embodiments of the invention will be described in conjunction with the accompanying drawings, in which, if there are several embodiments, the features of these embodiments can be combined with each other without conflict. When the description refers to the accompanying drawings, like numbers or symbols in different drawings represent the same or similar elements unless otherwise specified. The statements made in the following exemplary embodiments do not represent all embodiments of the invention, but rather they are merely examples of products consistent with the invention as recited in the claims.
The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. It should be understood that the use of terms such as "first," "second," and the like, in the description and in the claims of the present invention do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another.
Referring to fig. 1 to 9, the present invention discloses an exhaust gas aftertreatment package 100, which includes a carrier assembly 3, a first end cone 1 connected to one end of the carrier assembly 3, a second end cone 2 connected to the other end of the carrier assembly 3, a first supporting sleeve 4, a second supporting sleeve 5, a first steel wool gasket 6, and a second steel wool gasket 7.
Specifically, in the illustrated embodiment of the present invention, the carrier assembly 3 includes a housing 31 and a carrier 32 enclosed in the housing 31. The housing 31 includes a first end 311 at one end and a second end 312 at the other end. The second end 312 is disposed opposite to the first end 311. The first end 311 is provided with a first external thread 3111 and the second end 312 is provided with a second external thread 3121.
The first end cone 1 and the second end cone 2 are detachably connected to the housing 31 by a screw mechanism. Specifically, the first end cone 1 is provided with a first internal thread 11 matching with the first external thread 3111. The second end cone 2 is provided with a second internal thread 21 which is matched with the second external thread 3121. In the illustrated embodiment of the present invention, the diameter of the housing 31 is smaller than the diameter of the opening of the first end cone 1 connected to the housing 31, and the diameter of the housing 31 is also smaller than the diameter of the opening of the second end cone 2 connected to the housing 31. In other words, the outer side of the housing 31 is retracted radially inside the first end cone 1 and the second end cone 2.
The first support sleeve 4 includes a first body portion 40 fixed within the first end portion 311, a first protrusion portion 41 protruding radially outward from one end of the first body portion 40 to the first body portion 40, and a second protrusion portion 42 protruding radially inward from the other end of the first body portion 40 to the first body portion 40. The first body portion 40 can support the first end portion 311 in the radial direction. The first protrusion 41 is used to abut against the first end 311 along the axial direction to limit the first end 311. In addition, the first end cone 1 is provided with a first limiting strip 12 protruding inwards, and the first limiting strip 12 is used for being abutted against the first protruding part 41 along the axial direction to limit the first protruding part 41, so that better limiting is realized.
The first steel wool gasket 6 is accommodated in the shell 31 and located at one end of the carrier 32. The second protruding portion 42 abuts against the first steel wool gasket 6 along the axial direction to limit the first steel wool gasket 6. The first steel wool gasket 6 can play a role in buffering the end face of the carrier 32 which is in contact with the first steel wool gasket, so that the risk of carrier breakage is reduced.
Similarly, the second support sleeve 5 includes a second body portion 50 fixed within the second end portion 312, a third protrusion 51 protruding the second body portion 50 radially outward from one end of the second body portion 50, and a fourth protrusion 52 protruding the second body portion 50 radially inward from the other end of the second body portion 50. The second body portion 50 can support the second end portion 312 in the radial direction. The third protrusion 51 is configured to abut against the second end 312 along the axial direction to limit the second end 312. In addition, the second end cone 2 is provided with a second limiting strip 22 protruding inwards, and the second limiting strip 22 is used for being abutted against the third protruding part 51 along the axial direction to limit the third protruding part 51, so that better limiting is realized.
The second steel wool gasket 7 is accommodated in the housing 31 and located at the other end of the carrier 32, and the fourth protrusion 52 abuts against the second steel wool gasket 7 along the axial direction to limit the second steel wool gasket 7. The second steel wool gasket 7 can play a role in buffering the end face of the carrier 32 which is in contact with the second steel wool gasket, so that the risk of carrier breakage is reduced.
Preferably, the first end cone 1 and the second end cone 2 can be shared by parts, so that the number of dies is reduced, and the cost is reduced.
When the carrier 32 is damaged or blocked, the first end cone 1 and the second end cone 2 are screwed, the first support sleeve 4, the second support sleeve 5, the first steel wool washer 6 and the second steel wool washer 7 are taken out, and then the carrier 32 which needs to be replaced or repaired is taken out.
Compared to the prior art, the exhaust aftertreatment package of the present invention facilitates maintenance and replacement of the carrier 32.
The above embodiments are only for illustrating the invention and not for limiting the technical solutions described in the invention, and the understanding of the present description should be based on the technical personnel in the field, and although the present invention has been described in detail by referring to the above embodiments, the technical personnel in the field should understand that the technical personnel in the field can still make modifications or equivalent substitutions to the present invention, and all technical solutions and modifications thereof without departing from the spirit and scope of the present invention should be covered in the claims of the present invention.
