[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0019] Referring to the attached Figures 1-4 , a blast furnace for reducing steel from steel-containing waste, includes a blast furnace body 1. A blast furnace base 2 is fixedly connected to the bottom end of the blast furnace body 1. A blast furnace interface 4 is provided on the side of the blast furnace base 2. A blower interface 5 is inserted on the side of the blast furnace interface 4. A blower 3 is arranged on the side of the blast furnace body 1. The blower 3 is communicatively connected with the blower interface 5. An outer insertion tube 6 is fixedly connected to the outer wall of the blower interface 5. The outer insertion tube 6 is sleeved outside the blast furnace interface 4. An auxiliary groove 7 is provided inside the outer insertion tube 6. A pulling groove 9 is provided inside the auxiliary groove 7. A pulling groove 9 is provided on the outer wall of the blast furnace interface 4. An outer insertion block 10 is inserted into the pulling groove 9. A first limiting groove 8 is provided on the outer wall of the blast furnace interface 4. The outer insertion block 10 is inserted into the first limiting groove 8. A first spring 13 is wound around the outer wall of the outer insertion block 10. The first spring 13 passes through the pulling groove 9 and is fixedly connected to an auxiliary block 11; the insertion of the outer insertion block 10 into the first limiting groove 8 enables the outer insertion tube 6 and the blower interface 5 to stably insert the blower interface 5, thereby achieving the effect of fixing the blower 3 and the blast furnace body 1.
[0020] Then, an outer pulling ring 12 is fixedly connected to the outer wall of the auxiliary block 11. The outer pulling ring 12 is annularly arranged; through this mechanism, pulling the outer pulling ring 12 outwards drives the auxiliary block 11 and the outer insertion block 10, and drives the first limiting groove 8 to release the limit, thereby achieving the effect of releasing the installation of the blower 3 and the blast furnace body 1.
[0021] Subsequently, one end of the first spring 13 is fixedly connected to the auxiliary groove 7, and the other end of the first spring 13 is fixedly connected to the outer insertion block 10; through this structure, the elastic performance of the first spring 13 is utilized to drive the outer insertion block 10 to insert into the first limiting groove 8 more stably.
[0022] Next, a regulating column 14 is fixedly connected to the bottom end of the blower 3. A support column 15 is inserted into the regulating column 14. A moving groove 17 is formed inside the support column 15. A first limiting groove 8 is arranged inside the moving groove 17. A pressing and regulating block 19 is slidably connected inside the moving groove 17. A second limiting groove 16 is formed on the outer wall of the regulating column 14. The pressing and regulating block 19 passes through the moving groove 17 and is inserted into the second limiting groove 16. There are several groups of the second limiting grooves 16 arranged on the outer wall of the regulating column 14. Through this mechanism, the height of the blower 3 is adjusted by the movement of the regulating column 14 and the support column 15 to adapt to the blast furnace interfaces 4 at different heights, enabling the equipment to operate normally. Specifically, the limiting of the second limiting groove 16 can be released by pressing the pressing and regulating block 19 to drive the pressing and regulating block 19. Then, the regulating column 14 is adjusted. When the regulating column 14 is adjusted to the appropriate height, the corresponding position of the second limiting groove 16 can be released from being pressed by the pressing and regulating block 19, and it is reset by the second spring 18, so that the regulating column 14 and the support column 15 can be fixed again.
[0023] At this time, the outer wall of the support column 15 and the inner wall of the regulating column 14 are arranged in a fitting state; through this structure, the regulating column 14 slides stably, ensuring the stable operation of the equipment.
[0024] It should be noted that the outer wall of the pressing and regulating block 19 and the inner wall of the second limiting groove 16 are mutually fitted; through this structure, the pressing and regulating block 19 is more stable when inserted into the second limiting groove 16, ensuring the normal operation of the equipment.
