Abstract

The exhaust gas stirring device comprises a cylindrical frame on an inner surface of a flow path member forming an exhaust flow path; supporting parts arranged to radially reach across the frame; a shielding part shielding a central axis of the frame and its circumference in the axis direction of the frame. One of the supporting parts comprises a pair of first skeletons extending radially outwardly from the central axis of the frame. The frame and the supporting parts are configured by assembling assembling members. One of the assembling members comprises the pair of first skeletons, and second skeletons respectively extending in an arc shape from one end of each of the first skeletons and constituting a part of the frame. Each of the first skeletons and the second skeletons in the assembling members comprises a vane part formed to protrude respectively from each of the first and second skeletons.

First claim

1 . An exhaust gas stirring device that stirs an exhaust gas flowing through an exhaust flow path, comprising:
a frame in a cylindrical shape arranged on an inner surface of a flow path member that forms the exhaust flow path; a plurality of supporting parts arranged to reach across the frame in a radial direction; a shielding part shielding a central axis of the frame and its circumference in an axis direction of the frame, wherein a first one of the plurality of supporting parts comprises a pair of first skeletons that extends outwardly from the central axis of the frame in a radial direction, wherein the frame and the plurality of supporting parts are configured by assembling at least a plurality of assembling members, wherein a first one of the plurality of assembling members comprises the pair of first skeletons, and second skeletons that are respectively extended in an arc shape from one end of each one of the pair of first skeletons and constitute a part of the frame, and wherein each one of the pair of first skeletons and the second skeletons in the plurality of assembling members comprises a vane part that is formed to protrude respectively from each one of the pair of first skeletons and the second skeletons.

2 . The exhaust gas stirring device according to claim 1 , wherein the first one of the plurality of assembling members comprises the first one of the plurality of supporting parts having the pair of first skeletons, and a pair of the second skeletons respectively extended in an arc shape from both ends of the first one of the plurality of supporting parts.

3 . The exhaust gas stirring device according to claim 2 ,
wherein, in the first one of the plurality of assembling members, the vane parts disposed respectively on the pair of first skeletons are formed in an identical shape, and the vane parts disposed respectively on the pair of the second skeletons are formed in an identical shape.

4 . The exhaust gas stirring device according to claim 1 ,
wherein, in the plurality of assembling members, all of the vane parts disposed on the pair of first skeletons are formed in an identical shape, and all of the vane parts disposed on the second skeletons are formed in an identical shape.

5 . The exhaust gas stirring device according to claim 1 ,
wherein the first one of the plurality of assembling members is configured with one metal plate member.

6 . The exhaust gas stirring device according to claim 1 ,
wherein the plurality of supporting parts are spaced at equal intervals so that distances between each of the plurality of supporting parts in the circumferential direction of the frame are equal.
