An arc-shaped docking block 8 is abutted on the converter 4 at a position opposite to the limiting block 7. Several docking grooves 9 are formed on the arc-shaped docking block 8. In this embodiment, when the converter 4 is adjusted in angle, the first limiting cylinder 6 can insert the limiting block 7 into the corresponding docking groove 9, thereby limiting the position of the converter 4 when it rotates to a certain angle, ensuring stability.

[0025] The flue gas exhaust device includes a flue gas exhaust pipe 10, which is located on the top of the converter 4. A flue gas conveying sleeve 11 is movably fitted on the flue gas exhaust pipe 10. A flue gas conveying hose 12 is fixed on the flue gas conveying sleeve 11. A connecting rod 13 is fixed on the flue gas conveying sleeve 11. The connecting rod 13 is fixed on the rotor of a rotating motor 14. The rotating motor 14 is vertically fixed upward on a support plate. The support plate is movably fixed on the piston rod of a telescopic cylinder 15. The telescopic cylinder 15 is vertically fixed upward on the top of the converter 4 support 1.

[0026] In this embodiment, by rotating the motor 14 and the telescopic cylinder 15, the smoke conveying sleeve 11 can be removed from the exhaust pipe 10 for easy cleaning, and the smoke conveying hose 12 is connected to the external negative pressure smoke extraction pipe.

[0027] The drive brake device includes a drive bracket 16, a drive motor 17 is horizontally mounted on the drive bracket 16, a drive shaft 18 is fixed on the rotor of the drive motor 17, a drive gear 19 is fixed on the drive shaft 18, and a driven gear 33 is fixed on the second rotating shaft 3. The drive gear 19 and the driven gear 33 mesh together.

[0028] A first support plate 20 and a second support plate 21 are arranged sequentially from top to bottom on the left side of the drive bracket 16. A first drive cylinder 22 is arranged vertically downward on the first support plate 20. A first arc-shaped brake pad 24 is fixed on the piston rod of the first drive cylinder 22. The first arc-shaped brake pad 24 can be attached to the second rotating shaft 3. A second drive cylinder 23 is arranged vertically upward on the second support plate 21. A second arc-shaped brake pad 25 is fixed on the piston rod of the second drive cylinder 23. The second arc-shaped brake pad 25 can be attached to the second rotating shaft 3.

[0029] In this embodiment, when the converter 4 is adjusting its angle, the first arc-shaped brake pad 24 and the second arc-shaped brake pad 25 can be tightly attached to the second rotating shaft 3 by the first driving cylinder 22 and the second driving cylinder 23 respectively to achieve limiting, disperse stress, and ensure stability again.

[0030] The receiving and transferring device includes a second support plate 26, which is vertically fixed to the converter 4 support 1, and the second support plate 26 is arranged correspondingly to the first support plate 5 and the second support plate 26. A plurality of sliding limit rods 27 are provided between the first support plate 5 and the second support plate 26. A sliding support block 28 is slidably engaged on each sliding limit rod 27. A lifting cylinder 29 is vertically mounted at the bottom of the sliding support block 28, and a receiving plate 30 is fixed to the piston rod of the lifting cylinder 29. A receiving and limiting groove 31 is formed on the receiving plate 30. A transfer cylinder 32 is horizontally mounted on the second support plate 26, and the piston rod of the transfer cylinder 32 is fixedly connected to the sliding support block 28. In this embodiment, the horizontal distance of the external receiving hopper can be adjusted by the transfer cylinder 32, and the height of the external receiving hopper can be adjusted by the lifting cylinder 29, thereby improving production efficiency.

[0031] Working principle: The smelting material is placed into the converter 4 through the guide pipe 34 on the side of the converter 4. At this time, the inlet of the guide pipe 34 faces upward. Then, the guide pipe is made horizontal by the drive motor 17. The material is heated by the oxygen lance at the tail of the converter 4. If it is necessary to clean the flue during the heating and smelting process, the telescopic cylinder 15 is activated to move upward a certain distance, so that the smoke conveying sleeve 11 is pulled away from the exhaust pipe 10. The rotating motor 14 is activated to rotate a certain angle, so that the exhaust pipe 10 and the smoke conveying hose 12 are completely separated, thus facilitating the cleaning of soot.

[0032] After smelting is completed, the drive motor 17 is started to drive the converter 4 to rotate at a certain angle to facilitate unloading. At this time, the first arc-shaped brake pad 24 and the second arc-shaped brake pad 25 are both attached to the surface of the second rotating shaft 3. When the angle is fixed, the first limit cylinder 6 is started to insert the limit block 7 into the corresponding docking groove 9 to limit the position of the converter 4. The two work together to disperse the pressure and improve stability.

[0033] Before rotation, the external receiving hopper can be placed in the receiving limiting groove 31. The height of the receiving hopper can be adjusted by lifting cylinder 29, and the distance between it and the guide pipe 34 of converter 4 can be adjusted by transfer cylinder 32. This allows the material in converter 4 to flow accurately into the external receiving hopper when it flows out through the side guide pipe 34. The above operation reduces the labor intensity of manual labor. Since the converter 4 support 1 is located underground, the external receiving hopper can be moved to a suitable position after receiving the material by lifting cylinder 29 and transfer cylinder 32, which is convenient for workers to operate.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
