A limiting groove 7 is provided inside the gasification furnace 1. A slag discharge pipe 3 is fixedly connected to the bottom of the gasification furnace 1. The slag discharge pipe 3 needs to be sealed with a sealing component under normal conditions, and the slag discharge pipe 3 can be sealed with a sealing plug or a valve, thereby preventing leakage of raw materials during the gasification process. Support legs 4 are fixedly installed at the bottom of the gasification furnace 1. The support legs 4 are designed as triangular legs, which can improve the stability of the device during operation.

[0024] The gasification furnace 1 is equipped with a cleaning mechanism 5. This mechanism includes a motor 501 fixedly mounted on the top of the gasification furnace 1. The output end of the motor 501 is fixedly connected to a rotating shaft 502. The outer surface of the rotating shaft 502 rotates with the inner wall of the gasification furnace 1. A connecting bracket 503 is fixedly connected to the inner wall of the rotating shaft 502.

[0025] The connecting frame 503 is designed as a two-part structure. The upper and lower ends are designed as horizontal support rods for fixing the rotating shaft 1 502 to the scraper 504 and crushing plate 505. The middle portion of the connecting frame 503 is designed as an X-support frame. The X-support frame is used to securely connect the upper and lower horizontal support rods, thereby improving the support effect of the scraper 504 and crushing plate 505, preventing deformation during the slag crushing and scraping process. This improves the stability of the scraper 504 and crushing plate 505 during movement, thereby improving the slag cleaning effect of the scraper 504 and crushing plate 505. One end of the connecting frame 503 is fixedly connected to the scraper 504, and the outer surface of the scraper 504 contacts the inner wall of the gasification furnace 1. The end of the connecting frame 503 away from the scraper 504 is fixedly connected to the crushing plate 505, and the outer surface of the crushing plate 505 contacts the inner wall of the gasification furnace 1. The portion where the crushing plate 505 contacts the inner wall of the gasification furnace 1 is designed to be serrated, which can crush the slag on the inner wall of the gasification furnace 1, thereby improving the cleaning efficiency of the slag.

[0026] Turn on the motor 501. At this time, the motor 501 can drive the rotating shaft 502 to rotate. At the same time, the rotating shaft 502 will drive the connecting frame 503, the scraper 504 and the crushing plate 505 to rotate. Through the movement of the crushing plate 505 and the scraper 504, the slag on the inner wall of the gasification furnace 1 can be crushed and scraped away, thereby achieving the scraping and cleaning of the fireplace slag inside the gasification furnace 1.

[0027] The gasification furnace 1 is provided with a cleaning mechanism 6 inside. The cleaning mechanism 6 includes a second motor 601 fixedly mounted at the bottom of the gasification furnace 1. The output end of the second motor 601 is fixedly connected to a second rotating shaft 602, and the outer surface of the second rotating shaft 602 rotates with the inner wall of the gasification furnace 1. The end of the second rotating shaft 602 away from the second motor 601 is fixedly connected to a driving gear 603, and the driving gear 603 rotates with the limiting groove 7. The outer surface of the driving gear 603 is meshed with a driven gear 604, and the driven gear 604 rotates with the limiting groove 7. The inner wall of the driven gear 604 is fixedly connected to a limiting shaft 605, and the limiting shaft 605 rotates with the limiting groove 7. The outer surface of the limiting shaft 605 is fixedly connected to a cleaning plate 606, and the bottom surface of the cleaning plate 606 contacts the inner bottom wall of the gasification furnace 1.

At the same time, driving gear 603 will drive driven gear 604 and limiting shaft 605 to rotate. Then limiting shaft 605 will drive cleaning plate 606 to rotate. At this time, cleaning plate 606 will scrape off the slag adhered to the bottom wall of the gasification furnace 1. At the same time, the cleaning mechanism 6 can facilitate the collection of slag above the slag discharge pipe 3, so that the slag can be discharged through the slag discharge pipe 3 later.

[0029] Working principle: When the present invention is in use, the motor 501 can be turned on by an external controller. At this time, the motor 501 can drive the rotating shaft 502 to rotate, and the rotating shaft 502 will drive the connecting frame 503, the scraper 504 and the crushing plate 505 to rotate accordingly. The movement of the crushing plate 505 can crush the slag on the inner wall of the gasification furnace 1, and the crushed slag can be scraped off by the moving scraper 504. At the same time, the provided connecting frame 503 can support the scraper 504 and the crushing plate 505 to avoid deformation during the crushing and scraping process of the slag, thereby improving the stability of the scraper 504 and the crushing plate 505 during movement, thereby improving the cleaning effect of the scraper 504 and the crushing plate 505 on the slag. The motor 2 601 is turned on by the external controller. At this time, the motor 2 601 will drive the rotating shaft 2 602 and the driving gear 603 to rotate.

At the same time, the cleaning mechanism 6 can facilitate the concentration of the slag above the slag discharge pipe 3. The slag discharge pipe 3 is provided to facilitate the discharge of the slag. The cleaning mechanism 5, the cleaning mechanism 6 and the slag discharge pipe 3 cooperate with each other to facilitate the scraping and cleaning of the slag adhered to the furnace wall of the gasification furnace 1, thereby ensuring the production efficiency of the device, while improving the service life of the furnace wall and reducing the equipment maintenance cost.
