[0002] The converter is a cylindrical oxygen-blowing steelmaking container that can be tilted. The furnace body is cylindrical and mounted on a horizontal axis frame and can rotate. The converter flue, also known as the waste heat boiler, is one of the main supporting equipment for converter steelmaking. The converter flue is usually composed of multiple parts, including a movable smoke hood, a fixed section flue at the furnace mouth, an intermediate section flue, and a final section flue. These parts are connected in sequence to form a complete flue system. When working, the flue system must collect high-temperature flue gas to the maximum extent, withstand the highest furnace gas temperature and drastic and frequent temperature changes, and at the same time, the working conditions are the worst, and it is most likely to adhere to the splashed steel slag, forming a situation of flue scaling. Therefore, in addition to soot, there is also adhered dirt in the flue.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment

[0027] As Figure 1 shown, an efficient flue cleaning device for converter steelmaking includes a main body 1 of the cleaning device. The main body 1 of the cleaning device includes a sleeved barrel, a fixed circular plate, a telescopic cylinder assembly, a telescopic rod, a servo motor, a rotating shaft, an ash cleaning structure one 2, an ash cleaning structure two 3, and an ash collection structure 4. The ash cleaning structure two 3 includes a fixed rod 5, and a descaling structure 6 is connected to the side of the fixed rod 5 close to the ash cleaning structure one 2.

[0028] Specifically, when the servo motor drives the ash cleaning structure 1 to rotate, it will also drive the fixed rod 5 to rotate. One end of the fixed rod 5 is connected to the ash cleaning structure 2, and the other end is connected to the scale cleaning structure 6. When the fixed rod 5 rotates, it will drive the ash cleaning structure 2 and the scale cleaning structure 6 to rotate together. By setting the scale cleaning structure 6, the device can not only clean the soot, but also clean the adhered dirt, thus making the cleaning efficiency of the whole device higher.

[0029] As Figure 2 shown, the scale cleaning structure 6 includes a connecting rod 7 connected to the fixed rod 5. The front and back surfaces of the connecting rod 7 are sequentially connected with a scale cleaning component 1 8 and a scale cleaning component 2 9 from left to right.

[0030] Specifically, the connecting rod 7 plays a fixing role for the scale cleaning component 1 8 and the scale cleaning component 2 9. By setting the scale cleaning component 1 8 and the scale cleaning component 2 9, the cleaning range is enlarged, which is more conducive to improving the cleaning efficiency.

[0031] As Figure 3 shown, the scale cleaning component 1 8 includes a bidirectional telescopic rod 1 10 passing through the connecting rod 7. One end of the bidirectional telescopic rod 1 10 away from the connecting rod 7 is connected with a first fixing block 11. A connecting port 12 is opened on the side of the first fixing block 11 away from the connecting rod 7, and a scraping knife 13 is connected at the connecting port 12.

[0032] Specifically, through the telescopic movement of the bidirectional telescopic rod 1 10, the scraping knives 13 at both ends of the bidirectional telescopic rod 1 10 are closely attached to the inner surface of the flue. By the rotation of the fixed rod 5, the scraping knives 13 are driven to rotate and scrape the adhered dirt on the inner surface of the flue, so as to scrape off the adhered dirt.

[0033] As Figure 3 shown, the scraping knife 13 is T-shaped. A first connection hole 14 is opened on the knife handle, and a second connection hole 15 is opened on the corresponding first fixing block 11. The scraping knife 13 and the first fixing block 11 are connected by bolts 16 and their corresponding nuts.

[0034] Specifically, by setting the scraping knife 13 to be T-shaped, when the fixed rod 5 rotates in different forward and reverse directions, the scraping knife 13 can scrape the inner surface of the flue without replacing the scraping knife 13. By setting the scraping knife 13 and the first fixing block 11 to be connected by bolts 16 and their corresponding nuts, the bolts 16 are tightly connected, and at the same time, it is convenient to replace the scraping knife 13 when the scraping knife 13 is damaged.

[0035] As Figure 4 shown, the scale cleaning component 2 9 includes a bidirectional telescopic rod 2 17 passing through the connecting rod 7. One end of the bidirectional telescopic rod 2 17 away from the connecting rod 7 is connected with a second fixing block 18. An internal thread hole 19 is opened on the side of the second fixing block 18 away from the connecting rod 7, and a friction component 20 is connected at the internal thread hole 19.

[0036] Specifically, through the telescopic movement of the double-acting telescopic rod II 17, the friction components 20 at both ends of the double-acting telescopic rod II 17 are closely attached to the inner surface of the flue. By rotating the fixed rod 5, the friction components 20 are driven to rotate and rub the dirt adhered to the inner surface of the flue, so as to rub off the adhered dirt.

[0037] As Figure 5 shown, the friction component 20 includes a connecting block 21 connected to the second fixed block 18. An external thread 22 matching the internal thread hole 19 is provided on the connecting block 21. A steel wool 23 is connected to one end of the connecting block 21 away from the second fixed block 18.

[0038] Specifically, by providing the external thread 22, it is convenient for the connection and disassembly of the friction component 20 and the second fixed block 18. At the same time, the steel wool 23 has a strong frictional scraping force on the inner surface of the flue, and can effectively remove the adhered dirt.

[0039] As Figure 5 shown, anti-slip lines 24 are provided on the side wall of the connecting block 21.

[0040] Specifically, by providing the anti-slip lines 24, the frictional force between the human hand and the connecting block 21 can be increased, which is convenient for the connection and disassembly of the friction component 20.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
