Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

The embodiment of the utility model provides a:

as shown in fig. 1 to 3, a mechanism having a function of sufficiently burning pulverized coal fed in a pipe includes a blower 1, a burner 2, and a duct 3 for feeding pulverized coal; a combustion chamber 20 is arranged in the combustion furnace 2, one end of the conveying pipeline 3 is communicated with the combustion chamber 20, and the other end of the conveying pipeline is communicated with the blower 1; the connection mode of the blower 1 and the delivery pipe 3 and the connection mode of the delivery pipe 3 and the combustion furnace 2 are the prior art, and will not be described in detail in the embodiment; in order to avoid that the pulverized coal always falls on one position in the combustion chamber 20 when being blown out from the conveying pipe 3, the structure of the conveying pipe 3 is improved in the technical scheme, and the specific improvement is as follows.

For convenience of explanation, it is assumed that the right end of the duct 3 is connected to the combustion furnace 2 and the left end of the duct 3 is connected to the blower 1.

The right end of the conveying pipeline 3 is provided with helical blades 4 for dispersing pulverized coal, in the embodiment, the number of the helical blades 4 is four, one end of each helical blade 4, which is mutually concentrated, is arranged on one connecting column 40, the other end of each helical blade is arranged on the inner wall of the conveying pipeline 3, and the length direction of the connecting column 40 arranged at the position is consistent with the length direction of the conveying pipeline 3; spliced pole 40 forms a whole with four helical blade 4, and all can't move, blows pulverized coal to this when locating when air-blower 1, and the air current that carries the pulverized coal will be the helicization under helical blade 4's effect, and the one end of following pipeline 3 simultaneously blows in the combustion chamber 20 for carry the pulverized coal and obtain the air current and scatter as far as possible, avoid piling up each other when falling into combustion chamber 20.
