[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In order to facilitate the cleaning of slag and avoid blockage, refer to Figure 1 , Figure 2 and Figure 3As shown, it comprises a boiler body 1, a slag receiving box 2, a slag discharge assembly and an auxiliary slag discharge assembly. The slag receiving box 2 is arranged vertically below the boiler body 1. The slag discharge port of the boiler body 1 extends into the slag receiving box 2. The slag discharge assembly is arranged in the slag receiving box 2. The auxiliary slag discharge assembly is used to discharge the residue missed during the slag discharge. When the boiler body 1 is used, the internal slag is discharged into the slag receiving box 2 through the discharge port. At this time, the motor 3 is started, and the power output of the motor 3 is The output end drives the rotating shaft to rotate, which drives the rotating roller 4 to rotate, so that the paddle 5 rotates accordingly, and the cleaning head 7 rotates at the same time. The cleaning head 7 pushes the slag discharged from the slag holding box 2 toward the side of the discharge port. The automated operation can clean the slag in time to avoid blockage, and the scraper 11 can be placed horizontally in the slag holding box 2 by pushing the telescopic rod 12 and the rotating block. As the telescopic rod 12 is pulled, the slider 9 slides in the strip groove 8, and the residue remaining in the slag holding box 2 can be scraped out.

[0020] In order to further discharge the slag inside the slag container 2, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the slag discharge assembly includes a motor 3 arranged outside the slag holding box 2, the power output end of the motor 3 extends to the slag holding box 2 and is connected to a rotating shaft, a rotating roller 4 is arranged outside the rotating shaft, and the rotating roller 4 can be driven to rotate by the motor 3 to drive the rotating shaft to rotate, and a bearing seat adapted to the rotating shaft is arranged on the side of the slag holding box 2 away from the motor 3 to facilitate the rotation of the rotating shaft. A paddle plate 5 is arranged at equal intervals around the outer side of the rotating roller 4, a spring 6 is arranged on the side of the paddle plate 5 away from the rotating roller 4, and the spring 6 is arranged in a plurality, and a cleaning head 7 is connected to the end of the spring 6 away from the paddle plate 5. When the rotating roller 4 drives the paddle plate 5 to rotate, its cleaning head 7 rotates with it, and the cleaning head 7 will abut against the inner wall of the slag holding box 2. At this time, the deformation of the spring 6 allows the cleaning head 7 to retract relatively, so that the cleaning head 7 can complete the rotation and discharge the slag. The auxiliary slag discharge assembly includes a strip groove 8 opened on one side of the slag holding box 2, and a slider 9 is provided in the strip groove 8, which can slide along the length direction of the strip groove 8. The slider 9 slides along the strip groove 8, which can drive the movement of the scraper 11 to discharge the slag remaining in the slag holding box 2, thereby improving the cleanliness. The slider 9 is provided with a groove on the side facing the discharge direction of the slag holding box 2, and a rotating plate 10 is provided in the groove. The rotating plate 10 extends to the outside of the groove and is connected to the scraper 11. The scraper 11 is hinged to the outer side of one end away from the rotating plate 10, and the telescopic rod 12 is extended to drive the scraper 11 to move closer to or away from the discharge port.

[0021] When in use, the slag inside the boiler body 1 is discharged into the slag receiving box 2 through the discharge port. At this time, the motor 3 is started, and the power output end of the motor 3 drives the rotating shaft to rotate, driving the rotating roller 4 to rotate, so that the paddle 5 rotates accordingly, and the cleaning head 7 rotates at the same time. The cleaning head 7 pushes the slag discharged from the slag receiving box 2 toward the side of the discharge port, so that the slag can be cleaned in time to avoid blockage, and the scraper 11 can be placed horizontally in the slag receiving box 2 by pushing the telescopic rod 12 and the rotating block is rotated. As the telescopic rod 12 is pulled, the slider 9 slides in the strip groove 8, and the residue remaining in the slag receiving box 2 can be scraped out.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
