[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Refer to the attached Figure 1-3 A boiler burner decoking device comprises a driving device, a boiler 1, and a placing tube 2. The placing tube 2 is installed on a cover along the axial direction of the boiler 1 through a bearing, so that the placing tube 2 can rotate on the boiler 1, and the placing tube 2 extends into the boiler 1. The driving device comprises a motor and a gear installed at the output end of the motor. The gear on the motor meshes with the gear ring arranged on the surface of the placing tube 2. The motor drives the placing tube 2 to rotate on the boiler 1. A pushing tube 3 is arranged in the placing tube 2 to slide along its axial direction. At least one pair of extension rods 24 are hinged on the pushing tube 3 through a pushing pin 31. The extension rod 24 pushes the pushing tube 3. The pushing rod 24 extends outward from the outside of the placement tube 2 and forms a lever structure with the placement tube 2. The extension rod 24 is provided with a scraper 26 for abutting against the inner wall of the boiler 1, pushing the push tube 3 toward the direction of the boiler 1, pushing the extension rod 24 at the hinge with the push tube 3, and the extension rod 24 of the lever structure tilts to both sides to drive the scraper 26 to extend toward the inner wall of the boiler 1 until it abuts, and then drives the placement tube 2 to rotate through the driving device, and drives the scraper 26 to scrape off the coke on the inner wall of the boiler 1.

[0027] In this embodiment, refer to the attached Figure 4 A pushing tube groove for accommodating the extension rod 24 is relatively arranged on the pushing tube 3. The length of the pushing tube groove is greater than the length of the stroke required for the extension rod 24 to swing, giving the extension rod 24 enough space for swinging. The pushing tube groove is in the shape of a strip and axially penetrates the side wall of the pushing tube 3, making it convenient to extend the extension rod 24 toward the inside of the boiler 1.

[0028] In this embodiment, refer to the attached Figure 5-6At least one pair of placement slots 21 are relatively opened on the placement tube 2, and an extension block 22 is fixedly installed on the placement slot 21. The two sides of the extension block 22 are fixedly installed on the two sides of the placement slot 21. The extension block 22 is a square structure with three sides inwardly concave and connected, and an extension slot 23 for accommodating the rotation of the extension rod 24 is arranged on the other side. That is to say, the extension block 22 is a pair of identical rectangular blocks arranged relatively, and one corner of the extension block 22 is connected to each other. The extension slot 23 is a notch for accommodating the rotation of the extension rod 24. When the extension rod 24 swings with the extension pin 25 as the center of the circle, it will not affect the downward swing of the extension rod 24 When the scraper 26 has finished scraping, the push tube 3 can be moved away from the boiler 1. At this time, the push tube 3 drives the extension rod 24 at the push pin 31 to move upward. At this time, the extension rod 24 extending to the outside of the placement tube 2 moves downward, and the extension rod 24 is close to both sides of the placement tube 2, which is convenient for taking the overall structure out of the boiler 1. Conversely, the extension rod 24 on the outside of the placement tube 2 can be supported on the extension block 22 to form a limit. At this time, the extension rod 24 is perpendicular to the placement tube 2, and the scraper 26 is supported on the inner wall of the boiler 1. The extension block 22 also hinges the extension rod 24 through the extension pin 25 to form a lever structure.

[0029] In this embodiment, a cap for supporting the pushing tube 3 is threadedly sleeved on the placement tube 2 located outside the boiler 1 .

[0030] In this embodiment, U-shaped connecting pieces are installed on the ends of the extension rod 24, and the extension rod 24 is placed between the connecting pieces and fixed by bolts.
