Description

Technical Field

[0001] This utility model relates to the field of plate technology, specifically to wear-resistant lining plates for the sintering operation area of ​​an ironmaking plant. Background Technology

[0002] Sintering is a crucial step in steel production. It involves mixing various powdered iron-containing raw materials with appropriate amounts of fuel, flux, and water. After mixing and pelletizing, the materials undergo a series of physicochemical changes on sintering equipment, binding the ore particles into lumps. The sintering process involves mixing and granulating iron ore powder, various fluxes, and fine coke, then feeding them into the sintering machine via a feeding system. The fine coke is ignited by an ignition furnace, and the sintering reaction is completed by ventilation fans. The high-heat sintered ore is then crushed, cooled, and screened before being sent to the blast furnace as the main raw material for smelting iron. During sintering, the ore raw materials are fed through a hopper.

[0003] Commonly available feeding hoppers use bolts to install high-chromium alloy welded wear-resistant steel plates as liners on the bottom of the inner wall to reduce wear. However, these bolts are worn by the ore during feeding, making it difficult to replace the high-chromium alloy welded wear-resistant steel plates later. This reduces the efficiency of replacing the high-chromium alloy welded wear-resistant steel plates. Furthermore, fixing the high-chromium alloy welded wear-resistant steel plates with bolts is time-consuming and requires tools such as wrenches, making it quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide wear-resistant liners for the sintering operation area of ​​an ironmaking plant, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant liner for the sintering area of ​​an ironmaking plant, comprising:

[0006] The wear-resistant liner body is located inside the hopper;

[0007] Two fixing blocks are respectively fixed on both sides of the inner wall of the hopper, and each fixing block is provided with a limiting mechanism for fixing the wear-resistant liner body.

[0008] Preferably, the wear-resistant liner body has slots on both sides, and the two fixing blocks are respectively inserted into the two slots to facilitate subsequent limiting work. Each of the two slots is fixed with a stop block to block the fixing block and limit its movement.

[0009] Preferably, the limiting mechanism includes a sliding groove inside the fixed block, a sliding plate inside the sliding groove, a limiting post fixed at the bottom of the sliding plate, a circular hole at the bottom of the fixed block through which the limiting post passes, limiting grooves on both sides of the wear-resistant liner body, a spring sleeved on the limiting post inside the sliding groove, a rectangular block at the top of the sliding plate inside the sliding groove, a cylinder fixed at the top of the rectangular block through the top of the fixed block, the cylinder rotating on the fixed block, a rotating plate fixed at the top of the cylinder, and a second rectangular groove at the top of the sliding groove. The second rectangular groove and the rectangular block are inserted and engaged. By pressing the sliding plate downward with the rectangular block, the sliding plate moves the limiting post downward, and the limiting post inserts into the limiting groove on the wear-resistant liner body to limit the wear-resistant liner body.

[0010] Preferably, the spring is in a compressed state within the sliding groove, which facilitates its upward contact with the rectangular block.

[0011] Preferably, the limiting groove corresponds to the limiting post, and the limiting post can be inserted into the limiting groove, so that the limiting post can cooperate with the fixing block to limit the wear-resistant liner body.

[0012] Preferably, a first protrusion is fixed to the top of the fixed block, and a second protrusion is fixed to the rotating plate. When the first protrusion and the second protrusion correspond to each other, the bottom end of the limiting post is located inside the rectangular groove, which makes it easy to observe the state of the limiting post.

[0013] Preferably, a rectangular groove is provided at the top of the sliding groove. The rectangular groove and the rectangular groove are perpendicular to each other. The rectangular block is inserted into the rectangular groove. The rectangular groove can limit the rectangular block and prevent the rectangular block from rotating.

[0014] Preferably, there is a depth difference between the second rectangular groove and the first rectangular groove. When the rectangular block is inside the first rectangular groove, the limiting post is inside the second rectangular groove. When the rectangular block is inside the second limiting groove, the limiting post is disengaged from the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting the limiting mechanism on the top of both sides of the wear-resistant liner body, the ore can be prevented from directly contacting the limiting mechanism, thus avoiding wear of the limiting mechanism and facilitating the replacement of the wear-resistant liner body in the future.

[0017] 2. By pressing the sliding plate downwards with the rectangular block, the sliding plate drives the limiting post to move downwards. The limiting post inserts into the limiting groove on the wear-resistant liner body to limit the wear-resistant liner body. The installation and disassembly speed is fast, which can improve the replacement efficiency of the wear-resistant liner body. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 One embodiment of this utility model provides: a wear-resistant liner plate for the sintering operation area of ​​an ironmaking plant, comprising:

[0027] Wear-resistant liner body 2 is located inside the hopper 1;

[0028] Two fixing blocks 3 are fixed on both sides of the inner wall of the hopper 1, and each fixing block 3 is provided with a limiting mechanism for fixing the wear-resistant liner body 2.

[0029] Furthermore, slots 10 are provided on both sides of the wear-resistant liner body 2, and two fixing blocks 3 are respectively inserted into the two slots 10 to facilitate subsequent limiting work. Stop blocks 4 are fixed on the two slots 10 to block the fixing blocks 3 and limit the fixing blocks 3 to prevent the fixing blocks 3 from sliding in the slots 10. At the same time, the fixing blocks 3 can limit the wear-resistant liner body 2 longitudinally to prevent the wear-resistant steel plate from moving longitudinally.

[0030] Furthermore, the limiting mechanism includes a sliding groove 14 inside the fixed block 3, a sliding plate 13 inside the sliding groove 14, a limiting post 15 fixed at the bottom of the sliding plate 13, a round hole at the bottom of the fixed block 3 through which the limiting post 15 can pass, limiting grooves 9 on both sides of the wear-resistant liner body 2, a spring 11 sleeved on the limiting post 15 inside the sliding groove 14, a rectangular block 12 at the top of the sliding plate 13 inside the sliding groove 14, the rectangular block 12 in contact with the sliding plate 13, and a round post fixed at the top of the rectangular block 12. The column 8 passes through the top of the fixed block 3 and can rotate on the fixed block 3. A rotating plate 7 is fixed on the top of the column 8. A rectangular groove 17 is opened on the top of the sliding groove 14. The rectangular groove 17 and the rectangular block 12 are inserted and cooperate. The spring 11 is in a compressed state in the sliding groove 14, which makes it easy to push the rectangular block 12 upward, so that the rectangular block 12 enters the rectangular groove 16 or the rectangular groove 17. The limiting groove 9 corresponds to the limiting post 15. The limiting post 15 can be inserted into the limiting groove 9, which makes it easy for the limiting post 15 to cooperate with the fixed block 3 to limit the wear-resistant liner body 2. Press down on the rotating plate 7. The rotating plate 7, through the cylinder 8, drives the rectangular block 12 to press down on the sliding plate 13. The sliding plate 13 drives the limiting post 15 to move downward. The sliding plate 13 will further compress the spring 11. Then rotate the rotating plate 7 ninety degrees and release the rotating plate 7. Under the action of the spring 11, the rotating plate 7 will push upward against the rectangular groove 16. The rectangular groove 16 limits the rectangular block 12. At this time, the limiting post 15 is inserted into the limiting groove 9 on the wear-resistant liner body 2, thereby limiting the wear-resistant liner body 2 and completing the quick fixation of the wear-resistant steel plate. When it is necessary to remove the wear-resistant liner body 2, press down on the rotating plate 7 again and rotate it ninety degrees. Release the rotating plate 7. Under the action of the spring 11, the rectangular block 12 will abut against the rectangular groove 17. At this time, the limiting post 15 will disengage from the limiting groove 9, making it easy to remove the wear-resistant liner body 2.

[0031] Furthermore, a protrusion 5 is fixed to the top of the fixed block 3, and a protrusion 6 is fixed to the rotating plate 7. When protrusion 5 and protrusion 6 correspond, the bottom end of the limiting post 15 is located inside the rectangular groove 16, which makes it easy to observe the state of the limiting post 15.

[0032] Furthermore, a rectangular groove 16 is provided at the top of the sliding groove 14. The rectangular groove 16 and the rectangular groove 17 are perpendicular to each other. The rectangular block 12 is inserted into the rectangular groove 16. The rectangular groove 16 can limit the rectangular block 12 and prevent the rectangular block 12 from rotating. There is a depth difference between the rectangular groove 17 and the rectangular groove 16. The rectangular groove 17 is deeper than the rectangular groove 16. When the rectangular block 12 is inside the rectangular groove 16, the limiting post 15 is inside the limiting groove 9. When the rectangular block 12 is inside the rectangular groove 17, the limiting post 15 is disengaged from the limiting groove 9.

[0033] Among them, the wear-resistant liner body 2 is a high-chromium alloy welded wear-resistant steel plate.

[0034] When installing the wear-resistant liner body 2, it is necessary to ensure that the angle difference between protrusion 1 5 and protrusion 2 6 is 90 degrees. Then, align the groove 10 on the wear-resistant liner body 2 with the fixing block 3 and insert it until the stop block 4 blocks the fixing block 3. Then, press down and twist the rotating plate 7 to align protrusion 1 5 and protrusion 2 6. Release the rotating plate 7 to complete the installation of the wear-resistant liner body 2.

[0035] When disassembling the wear-resistant liner body 2, press down and twist the rotating plate 7 to create a 90-degree angle difference between protrusion 1 5 and protrusion 2 6. Then release the rotating plate 7 to remove the wear-resistant liner body 2.
