[0020] Please refer to Figures 1-5, the present utility model provides a technical solution: an efficient and energy-saving biomass hot blast stove, including a conveying pipe 1, a fitting block 2, a connecting ring 13 and a fixing block 24. On one side of the inner wall of the conveying pipe 1, there is a connecting ring 13. On the outer wall of one side of the connecting ring 13, there is a support frame 15 installed. On the outer wall of the upper end of the support frame 15, there is a first magnet 16 installed. On one side of the upper outer wall of the conveying pipe 1, there is a fitting block 2 embedded and installed. On one side of the upper outer wall of the fitting block 2, there is a chute 21 opened. Inside the chute 21, there is a slider 22 slidably installed. On both sides of the upper outer wall of the fitting block 2, there are fixing blocks 24 installed.

[0021] On the outer wall of the connecting ring 13, there is a scraper 14 installed. The scraper 14 is in contact with the inner wall of the conveying pipe 1. Through the scraper 14, the connecting ring 13 can scrape and clean the inner walls of the conveying pipe 1 and the fitting block 2.

[0022] On both sides of the inner wall of the conveying pipe 1, there are limiting rings 12 installed. The limiting rings 12 are distributed on both sides of the connecting ring 13. The limiting rings 12 limit the moving track of the connecting ring 13 and can block the falling-off objects.

[0023] On both sides of the lower outer wall of the conveying pipe 1, there are waste pipes 11 inserted and installed. On one side of the outer wall of the waste pipe 11, there is a valve. The falling-off objects inside the conveying pipe 1 can be discharged through the waste pipes 11, and the waste pipes 11 are controlled to be connected through the valve. The scraper 14 scrapes and cleans the inner walls of the conveying pipe 1 and the fitting block 2, so that the coke-like substances and particulate matters adhered to the inner walls of the conveying pipe 1 and the fitting block 2 fall off, and the falling-off objects are pushed to move until the falling-off objects move to the position of the waste pipes 11. The falling-off objects can be discharged through the waste pipes 11, ensuring the relative cleanliness of the inner wall of the conveying pipe 1, ensuring the conveying efficiency of the flue gas inside the conveying pipe 1, and achieving the effect of ensuring the heat exchange efficiency of the hot blast stove.

[0024] On one side of the lower outer wall of the slider 22, there is a second magnet 23 embedded and installed. The second magnet 23 attracts the first magnet 16. The slider 22 can drive the support frame 15 to move through the magnetic force between the first magnet 16 and the second magnet 23.

[0025] Inside the fixing block 24, there is a screw rod 25 rotatably installed. The screw rod 25 meshes with the inside of the slider 22. One end of the screw rod 25 penetrating through the fixing block 24 is provided with a motor body. The motor body drives the screw rod 25 to rotate in a circle, thereby being able to drive the slider 22 to move horizontally. The motor body drives the screw rod 25 to rotate in a circle, thereby driving the slider 22 to move horizontally inside the chute 21. The attractive force between the first magnet 16 and the second magnet 23 drives the support frame 15 and the connecting ring 13 to move accordingly.

[0026] Working principle: The motor body drives the screw rod 25 to rotate circumferentially, thereby driving the slider 22 to move horizontally inside the chute 21. The attraction between the first magnet 16 and the second magnet 23 drives the support frame 15 and the connecting ring 13 to move accordingly. And the inner walls of the conveying pipe 1 and the fitting block 2 are scraped and cleaned by the scraper 14, so that the coke deposits and particulate matters adhering to the inner walls of the conveying pipe 1 and the fitting block 2 fall off, and the fallen matters are pushed to move until the fallen matters move to the position of the waste pipe 11, and the fallen matters can be discharged through the waste pipe 11.
