Embodiment 1

[0028] Such as Figure 1-6 As shown, the edge chamfering structure of the honeycomb ceramic particle catcher according to the embodiment of the present invention includes a honeycomb ceramic particle catcher body 1, and the honeycomb ceramic particle catcher body 1 is composed of a central area 2 and an edge area 3, so The central area 2 is located in the middle of the honeycomb ceramic particle trap body 1, the edge area 3 is located inside the honeycomb ceramic particle trap body 1 and outside the central area 2, and the central area A number of channel holes 1 4 and a number of channel holes 2 5 are arranged inside the 2, and a number of channel holes 3 6 and a number of channel holes 4 7 are arranged inside the edge area 3 .

[0029] Let's talk about the specific settings and effects of channel hole one 4, channel hole two 5, channel hole three 6 and channel hole four 7 below.

[0030] Such as figure 1 As shown, channel hole 3 6 and channel hole 4 7 are respectively subj...

Embodiment 2

[0033] Such as Figure 1-6 As shown, the ratio of the diameter of the central area 2 to the diameter of the honeycomb ceramic particle trap body 1 is between 0-0.5, the first channel hole 4, the second channel hole 5, and the third channel hole 6 The cross-sections of the channel holes 4 and 7 are square structures respectively, the channel hole 1 4 and the channel hole 2 5 are non-chamfered structures, the channel hole 3 6 is a chamfered structure, and the channel The chamfering structure of hole three 6 is one of arc chamfering and straight chamfering, the channel hole four 7 is a chamfering structure, and the chamfering structure of the channel hole four 7 is arc chamfering and one of straight chamfers.

[0034] The ratio of the diameter of the central area 2 to the diameter of the honeycomb ceramic particle trap body 1 is between 0-0.5, and the optimum range of the diameter ratio of the central area 2 to the diameter of the honeycomb ceramic particle trap body 1 is 0.1 B...

Abstract

The invention discloses an edge chamfering structure of a honeycomb ceramic particle catcher. The edge chamfering structure of the honeycomb ceramic particle catcher comprises a honeycomb ceramic particle catcher body, the honeycomb ceramic particle catcher body is composed of a central area and an edge area, the central area is located at the center of the interior of the honeycomb ceramic particle catcher body, the edge area is located in the honeycomb ceramic particle catcher body and located on the outer side of the central area, a plurality of first channel holes and a plurality of secondchannel holes are formed in the central area, and a plurality of third channel holes and a plurality of fourth channel holes are formed in the edge area. The edge chamfering structure of the honeycomb ceramic particle catcher has the beneficial effects that design is simple and easy to operate, the thermal shock resisting capability of the particle catcher is enhanced by chamfering channel corners of the peripheral edge zone, and as only the structure of the edge zone is improved, little influences are generated on back pressure.

Description

technical field [0001] The invention relates to the technical field of a honeycomb ceramic particle catcher, in particular to an edge chamfering structure of a honeycomb ceramic particle catcher. Background technique [0002] Honeycomb ceramic particle trap technology has been widely used in automobile and truck exhaust gas treatment. Generally, honeycomb ceramic particle traps use wall-flow filtration to remove particles from exhaust gas. The principle is that every other hole is blocked at the entrance, and the other hole remains unobstructed; while at the exit, the corresponding hole remains blocked or open. In this way, the honeycomb ceramics are in the chessboard shape, ensuring that the exhaust gas must pass through the wall, so as to achieve the purpose of trapping the particles in the exhaust gas on the wall. [0003] In the application, the particles in the exhaust gas (such as carbon black) accumulate in the unblocked channel at the entrance. After reaching a c...
