[0026] A valve 41 is connected to the top of the ash discharge pipe 4, and a first expansion joint 42 and a second expansion joint 43 are arranged at the bottom of the valve 41 from bottom to top. The first expansion joint 42 and the second expansion joint 43 are both arranged on the body of the ash discharge pipe 4.
[0027] A rapping assembly 44 is provided between the first expansion joint 42 and the second expansion joint 43 , and the rapping assembly 44 is connected to the pipe body of the ash discharge pipe 4 .
[0028] For details, please refer to the attached Figure 1 and 2 The rapping assembly 44 includes a convex ring 441 connected to the outer surface of the ash discharge pipe 4, a motor 442 connected to the upper surface of the convex ring 441, and an active rotating ring 443 connected to the output shaft of the motor 442, and the outer surface of the active rotating ring 443 is rotatably connected to a first hammer 444;
[0029] The first hammer 444 includes a first connecting rod 4441 rotatably connected to the outside of the active rotating ring 443, and a hammer head 4442 rotatably connected to an end of the first connecting rod 4441 away from the active rotating ring 443 via a rotating shaft;
[0030] The outer surface of the ash discharge pipe 4 is connected to a plurality of striking plates 45, and the plurality of striking plates 45 are arranged in a circular array around the ash discharge pipe 4;
[0031] It should be noted that, in this embodiment, when the motor 442 drives its output shaft to rotate, the output shaft drives the active rotating ring 443 connected thereto to rotate, thereby driving the first hammer 444, so that the first hammer 444 hammers the struck plate 45, causing the body of the ash discharge pipe 4 to vibrate, so as to shake off the accumulated ash attached to the body of the ash discharge pipe 4;
[0032] Furthermore, the first connecting rod 4441 moves with the active rotating ring 443, and the hammer head 4442 is driven by the first connecting rod 4441, so that the stroke of the hammer head 4442 when falling is longer and more powerful, thereby improving the vibration and dust removal effect;
[0033] Furthermore, the hammering of the first hammer 444 and the second hammer 446 is received by the hammering plate 45 , so as to facilitate the shaking and ash discharge of the ash discharge pipe 4 .

[0039] Furthermore, the first coupling 447 and the second coupling 448 are used to make the driven rotating ring 445 rotate following the rotation of the driving rotating ring 443. Since the driven rotating ring 445 surrounds the ash discharge pipe 4, it is convenient to vibrate the ash discharge pipe 4 from multiple angles.
[0040] The specific operation mode of the utility model is as follows:
[0041] When the low negative pressure sintering ignition system is used, negative pressure is generated inside the ignition wind direction chamber 1 under the action of exhaust, and the waste gas and accumulated materials enter the wind box branch pipe 2 through the ignition wind direction chamber 1, the waste gas enters the bypass air duct 3, and the accumulated ash enters the ash discharge pipe 4;
[0042] During the ash discharge process, the valve 41 is opened to allow the accumulated ash to fall down, and after the ash discharge, the valve 41 is closed. When the motor 442 drives its output shaft to rotate, the output shaft drives the active rotating ring 443 connected to it to rotate, thereby driving the first hammer 444, so that the first hammer 444 hammers the impact plate 45, causing the tube body of the ash discharge pipe 4 to vibrate, so as to shake off the accumulated ash attached to the tube body of the ash discharge pipe 4. In this process, the first expansion joint 42 and the second expansion joint 43 are arranged to absorb the vibration of the ash discharge pipe 4 and reduce the impact of the vibration on the bellows branch pipe 2.

As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
