Description

Technical Field

[0001] This invention belongs to the field of converter steelmaking technology, specifically relating to an intelligent auxiliary material addition device for converter steelmaking. Background Technology

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as main raw materials. Without external energy input, it relies on the physical heat of the molten iron itself and the chemical reactions between its components to generate heat, completing the steelmaking process within the converter. Converters are classified by refractory materials (acidic or basic), by the location of gas introduction (top-blown, bottom-blown, or side-blown), and by the type of gas used (air converters or oxygen converters). Basic oxygen top-blown and top-and-bottom combined-blown converters are the most widely used steelmaking equipment due to their high production speed, large output, high single-furnace output, low cost, and low investment.

[0003] The converter steelmaking process requires the addition of auxiliary materials, including slag-forming agents, coolants, carburizing agents, and deoxidizing alloys. These materials are added in batches, at designated points, automatically or manually, according to process stages. The core principles are "early slag formation, stable dephosphorization, temperature control, and uniform melting." However, blockages may occur during the feeding and conveying of auxiliary materials, leading to interruptions in feeding. This necessitates manual knocking or vibration to break up the blockages, disrupting the continuity of automation. Therefore, this application provides an intelligent auxiliary material adding device for converter steelmaking to solve the problem of feeding blockages.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0007] Preferably, the upper and lower ends of the connecting pipe are provided with a first flange and a second flange that cooperate with each other; the bottom of the first flange is provided with a limiting ring, and the limiting ring is provided with a bearing inside.

[0008] Preferably, the rotating assembly includes two limiting rings, which engage with the inner rings of the bearings at corresponding positions; multiple rotating rods are arranged between the two limiting rings, each rotating rod having a protrusion on its inner side that contacts the outer wall of the guide tube and a rotating sleeve on its outer side; the rotating sleeve has multiple guide strips on its inner wall that engage with the rotating rods and meshing teeth on its outer wall that engage with the driving assembly.

[0009] Preferably, a limiting groove is formed on the second limiting ring; the end of the rotating rod enters the limiting groove and is fixed by bolts.

[0012] Preferably, the two ends of the feed tube are fixed between the first flange and the second flange at corresponding positions.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) The intelligent auxiliary material adding device for converter steelmaking of the present invention, by setting a dredging component inside the connecting pipe, squeezes the material guide pipe when it is blocked, which can quickly dredge the blockage and avoid interrupting the feeding and affecting the working efficiency.

[0014] (2) The intelligent auxiliary material adding device for converter steelmaking of the present invention can squeeze the side wall of the guide pipe to different degrees by using protrusions of different sizes on adjacent rotating rods, which is beneficial to improving the unblocking effect.

[0015] (3) When the intelligent auxiliary material adding device for converter steelmaking of the present invention drives the rotating rod to rotate around the outside of the guide pipe, the guide pipe will not rotate, which facilitates the continuous change of the degree of compression at different positions of its side wall, which is beneficial to speeding up the unblocking efficiency.

[0020] See attached document Figure 1-5 A smart auxiliary material adding device for converter steelmaking includes: a silo 1, a connecting pipe 3, and a guide chute 2. The guide chute 2 is located below the silo 1; the connecting pipe 3 is located between the silo 1 and the guide chute 2, and is equipped with a guide pipe 4 and a clearing component inside.

[0021] In this embodiment, the unblocking component includes a rotating component and a driving component; the driving component is used to drive the rotating component to rotate around the outside of the guide pipe 4, and to squeeze the guide material, which can play a role in unblocking. The guide pipe 4 is made of a deformable material (such as a metal corrugated pipe, a metal skeleton + rubber composite pipe, etc.), which can return to its original state after being squeezed and deformed.

[0022] Specifically, the drive assembly includes a fixed frame 15 and a drive motor 16 and a reducer 17 located within the fixed frame 15; the fixed frame 15 is fixed to the outer wall of the connecting pipe 3 and communicates with the inside of the connecting pipe 3; the drive motor 16 is remotely intelligently controlled, and the output shaft of the reducer 17 is provided with a drive gear 18; a rotating shaft 19 is also provided inside the fixed frame 15, and a driven gear 20 is provided on the rotating shaft 19.

[0023] Both ends of the connecting pipe 3 are equipped with a first flange 5 and a second flange 6 that cooperate with each other. The two ends of the guide pipe 4 are respectively fixed between the first flange 5 and the second flange 6 at the corresponding positions. The bottom of the first flange 5 is provided with a limiting ring 7; in order to enable the rotating component to rotate, a bearing 8 is provided inside the limiting ring 7.

[0024] In this embodiment, the rotating assembly includes two limiting rings 9 and multiple rotating rods 10 disposed between the two limiting rings 9. The limiting rings 9 cooperate with the inner rings of the bearings 8 at corresponding positions so that the rotating assembly can rotate. The inner side of the rotating rod 10 is provided with a protrusion 11 that contacts the outer wall of the guide tube 4, and the protrusion 11 can squeeze the guide tube 4. The protrusions 11 on the inner side of adjacent rotating rods 10 are of different sizes, and the degree of squeezing the guide tube 4 is also different. A rotating sleeve 12 is provided on the outer side of the rotating rod 10. The inner wall of the rotating sleeve 12 is provided with multiple guide strips 13 that cooperate with the rotating rod 10, which facilitates installation and can also limit the rotation of the rotating sleeve 12.

[0025] On the other hand, a limiting groove 14 is provided on the limiting ring 2 9; the end of the rotating rod 10 enters the limiting groove 14 and is fixed by bolts. The outer wall of the rotating sleeve 12 is provided with meshing teeth that mesh with the driven gear 20, which in turn meshes with the driving gear 18. When the drive motor 16 starts, the rotating sleeve 12 will rotate, further driving the rotating rod 10 and the limiting ring 2 9 to rotate synchronously. When the rotating rod 10 rotates, the protrusion 11 on its inner side will squeeze the side wall of the guide tube 4 and continuously change its position, improving the unblocking effect and accelerating the unblocking efficiency.
