Description

Technical Field

[0001] This utility model belongs to the technical field of iron and steel metallurgical equipment, and specifically relates to a feeding and leveling device for a sintering ring cooler. Background Technology

[0002] In the steel production process, the sintering ring cooler is a key piece of equipment for cooling sintered ore. The flatness of the feed material plays a decisive role in the cooling effect of the sintered ore, the operational stability of the ring cooler, and the quality of the final product. Currently, common feeding and leveling methods have many drawbacks. Some companies still use manual leveling, which is not only inefficient but also makes it difficult to guarantee flatness, resulting in uneven cooling of the sintered ore and affecting product quality. Although some mechanical leveling devices improve efficiency to a certain extent, they are complex in structure, have high manufacturing costs, are difficult to maintain, and have poor adaptability to different working conditions and material characteristics, failing to effectively ensure uniform and flat feeding, thus affecting the overall performance and production efficiency of the ring cooler. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figure 1-7As shown, a sintering ring cooler feeding and leveling device includes: a support structure, which includes a top plate 1, with symmetrical support rods 2 fixedly connected to both sides of the lower end of the top plate 1, pulleys 26 fixedly connected to the lower ends of the support rods 2, slide rails 27 slidably connected to the lower ends of the pulleys 26, mounting plates 28 fixedly connected to the lower ends of the slide rails 27, and a first electric telescopic rod 3 fixedly connected to the lower middle of the top plate 1; a drive structure, which includes a U-shaped plate 4, which is disposed on the output end of the first electric telescopic rod 3, a drive motor 6 connected to the inner wall of one side of the U-shaped plate 4, a reciprocating screw 7 connected to the output end of the drive motor 6, a threaded sleeve 8 connected to the reciprocating screw 7, the threaded sleeve 8 slidably connected to the U-shaped plate 4, and a support column 10 fixedly connected to the lower end of the threaded sleeve 8; and a leveling structure, which includes a horizontal plate 14, which is connected to the support column 10 through a buffer structure, and a first scraper 17 fixedly connected to the lower middle of the horizontal plate 14. Specifically, the sliding connection structure is as follows: a first sliding groove 5 is opened on the U-shaped plate 4, a sliding rod 9 is slidably arranged in the first sliding groove 5, and the sliding rod 9 is fixedly connected to the screw sleeve 8.

[0028] When leveling the material fed into the sintering ring cooler is required, the mounting plate 28 is fixed to both sides of the sintering machine with bolts, and the slide rail 27 is stabilized on the mounting plate 28. Pushing the support rod 2, the support rod 2, under the sliding limit action of the pulley 26 and the slide rail 27, moves the entire device to the top of the material to be leveled. At this time, the first electric telescopic rod 3 and the drive motor 6 are simultaneously activated by an external power supply. The output end of the first electric telescopic rod 3 drives the U-shaped plate 4 to descend. When the U-shaped plate 4 descends, it drives the first scraper 17. When the scraper 17 comes into contact with the surface of the ore, the output end of the drive motor 6 drives the reciprocating screw 7 to rotate inside the U-shaped plate 4. At the same time, the reciprocating screw 7 drives the screw sleeve 8. When the screw sleeve 8 is driven, it works in conjunction with the sliding limit effect of the slide rod 9 and the first slide groove 5 to move stably on the wall of the reciprocating screw 7. At this time, the screw sleeve 8 drives the horizontal plate 14 and the first scraper 17 through the support column 10 to continuously flatten the surface of the ore, ensuring that the surface of the ore is uniform and flat. This solves the problem of uneven ore surface affecting the uneven cooling of sintered ore and ensures product quality.

[0029] Example 2:

[0030] Furthermore, this embodiment is basically the same as Embodiment 1, such as... Figure 1 , Figure 3 and Figure 7 As shown, the difference lies in the addition of a buffer structure in this embodiment, including: a connecting plate 11, a shock absorber 12, and an elastic element 13. The connecting plate 11 is located at the lower end of the support column 10, and the shock absorbers 12 are connected to both sides of the lower end of the connecting plate 11. The shock absorbers 12 are mainly responsible for absorbing and attenuating vibrations. The shock absorbers 12 are provided with elastic elements 13, which are springs that provide necessary support force and absorb and disperse the impact of external forces.

[0031] In this embodiment, the support column 10 drives the connecting plate 11 and the first scraper 17 to level the surface of the ore. Since the surface of the ore is uneven, the first scraper 17 will be damaged during the leveling process. At this time, the cross plate 14 compresses the elastic element 13 to shrink the shock absorber 12. The shock absorber 12 reduces the vibration through damping, and drives the first scraper 17 to level the surface of the ore with adaptive pressure. This solves the problem of poor adaptability to different material characteristics, reduces damage to the equipment, and reduces the difficulty of equipment maintenance.

[0032] Example 3:

[0033] Furthermore, in this embodiment, as Figure 1 , Figure 3 and Figure 7 As shown, in order to improve the flatness accuracy, a second electric telescopic rod 15 is added. The second electric telescopic rod 15 is fixedly connected to the lower surface of both sides of the connecting plate 11 near the edge. When the second electric telescopic rod 15 is extended, it abuts against the upper surface of the horizontal plate 14.

[0034] In this embodiment, when further leveling the surface of the ore, the second electric telescopic rod 15 is activated. The second electric telescopic rod 15 extends and abuts against the upper surface of the horizontal plate 14, controlling the compression force of the shock absorber 12 and the elastic element 13. At this time, the function of the above-mentioned buffer structure is ineffective, increasing the overall surface leveling accuracy of the ore.

[0035] Example 4:

[0036] Furthermore, in this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, to assist the first scraper 17, second scrapers 25 are provided on both sides of the first scraper 17. The specific connection structure is as follows: second sliding grooves 16 are provided on both sides of the lower end of the horizontal plate 14. The second sliding grooves 16 are slidably connected to the sliding plate 22. The lower end of the sliding plate 22 is fixedly connected to a toothed ring 23 with one side open. The middle of both sides of the first scraper 17 is fixedly connected to the mounting bracket 18. The bidirectional motor 19 is fixedly connected inside the mounting bracket 18. The output ends of both sides of the bidirectional motor 19 are fixedly connected to the rotating rod 20. The end of the rotating rod 20 away from the bidirectional motor 19 is fixedly connected to the half gear 21. The half gear 21 and the toothed ring 23 mesh with each other. The outer wall of the opening side of the toothed ring 23 is fixedly connected to the connecting rod 24. The side of the connecting rod 24 away from the toothed ring 23 is fixedly connected to the second scraper 25.

[0037] In this embodiment, while the first scraper 17 is leveling the surface of the ore, the bidirectional motor 19 is simultaneously started by an external power supply. The output ends of the bidirectional motor 19 drive the rotating rod 20 to rotate, which in turn drives the half gears 21 on both sides. When the half gears 21 rotate, they mesh and drive the gear ring 23. When the gear ring 23 moves, it drives the second scraper 25 through the connecting rod 24 to continuously level the material on both sides of the first scraper 17, further leveling the surface of the ore and effectively improving the leveling efficiency of the material.
