Description

Technical Field

[0001] The utility model relates to the technical field of slag scrapers, in particular to a slag scraper for metallurgy. Background Art

[0002] Blast furnace hot metal is the primary raw material for converter steelmaking. Its quality significantly impacts the converter smelting process, and improving its quality is a crucial step in improving the converter's technical and economic performance. Besides its composition and temperature, the amount of slag produced also significantly impacts converter performance, necessitating the use of a hot metal skimmer.

[0003] For example, the Chinese utility model patent with patent publication number CN220398272U includes a support frame, a slag removal mechanism, and a lifting mechanism. A support seat is provided at one end of the support frame, and the support seat moves along the length direction of the support frame; the slag removal mechanism is provided above the support frame, including a rotating frame with one end rotatably connected to the support seat, a slider that moves along its length direction is slidably fitted on the rotating frame, and a connecting rod is provided on the slider, and the connecting rod is arranged along the length direction of the rotating frame. This patent can remove slag with a relatively simple structure, which not only improves efficiency, does not cause a significant increase in cost, and can also avoid threats to the lives of workers. However, when using a slag removal plate for slag removal, residues often adhere to the slag removal plate. If there is a lot of residue attached to the slag removal plate, the surface of the slag removal plate will become uneven, which will lead to reduced efficiency in subsequent slag removal. Therefore, the slag removal plate needs to be cleaned after the slag removal is completed. In view of this, we have proposed a slag removal machine for metallurgy. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a metallurgical slag scraper that can solve the problem that residues on the surface of a slag scraper plate are difficult to clean.

[0005] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip.

[0006] Preferably, the locking assembly includes an electric push rod, which is fixedly connected to the right inner wall of the second sliding groove, and the output end of the electric push rod is fixedly connected to the locking rod.

[0007] Preferably, a locking plate is fixedly connected to the outer surface of the rotating shaft, and a groove extending from the right side surface of the U-shaped plate is formed on the left side surface.

[0008] Preferably, the left side surface of the locking plate is provided with a through groove extending from the right side surface thereof.

[0009] Preferably, the left end of the locking rod extends out of the left side surface of the locking plate through the through slot, and the front and rear side surfaces of the U-shaped plate are respectively fixedly connected to the limiting blocks.

[0010] Preferably, the left side surfaces of the two limit blocks are in contact with the right side surfaces of the two connecting sleeves respectively.

[0011] Preferably, the collecting assembly includes a collecting box, the collecting box is fixedly connected to the left side surface of the main body, and a triangular top block is fixedly connected to the left side surface of the collecting box.

[0012] Preferably, the left side surface of the triangular top block is arranged to be inclined, and the front side surface of the collection box is provided with a cabinet door.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The metallurgical scraper uses a rotating shaft to drive the connecting sleeve and the scraper plate to move. After the scraper plate moves, it contacts the collecting component. Since the rotating shaft can rotate at this time, the scraper plate is squeezed to rotate around the rotating shaft. After the scraper plate rotates, it becomes horizontal. Then the push rod continues to move so that the scraper plate contacts two cleaning plates in an eight-shaped shape, and then the two cleaning plates are used to complete the cleaning of the scraper plate surface. Through the above structure, when cleaning the outer surface of the scraper plate, it can be automatically cleaned in the process of retracting the scraper plate after unlocking the locking component, avoiding the problem that the outer surface of the scraper plate is too uneven due to the attachment of too much residue, which in turn causes the residue to be scraped to both sides by the protrusion during the scraping process, resulting in reduced efficiency.

[0015] (2) The metallurgical slag scraper uses an electric push rod to drive the locking rod to move. After the locking rod moves, it disengages from the locking plate, thereby completing the unlocking of the rotating shaft. Subsequently, during the process of retracting the slag scraper plate, the inclined surface of the triangular top block is used to make the slag scraper plate horizontal, thereby facilitating subsequent cleaning. At the same time, after cleaning the residue attached to the surface, the residue will fall into the interior of the collection box, facilitating the subsequent unified treatment of the residue. Through the above structure, not only can the unlocking and locking of the slag scraper plate be completed more conveniently, but the collection box can also be used to facilitate the subsequent unified treatment of the residue, and the limit block can be used to prevent the slag scraper plate from rotating to the right.

When the slag plate 8 is to be cleaned, the rotating shaft 6 is first unlocked by the locking assembly, thereby allowing the rotating shaft 6 to rotate, and then the telescopic rod 20 is used to drive the sliding block 3 to move to the right. When the sliding block 3 moves, it will synchronously drive the push rod 4 to move. When the push rod 4 moves, the U-shaped plate 5 is used to drive the rotating shaft 6 to move, and then the rotating shaft 6 is used to drive the connecting sleeve 7 and the slag plate 8 to move. After the slag plate 8 moves, it contacts the collecting assembly. Since the rotating shaft 6 can rotate at this time, the slag plate 8 is squeezed to rotate around the rotating shaft 6, and the slag is removed. After the plate 8 rotates, it becomes horizontal, and then the push rod 4 continues to move so that the scraping plate 8 contacts the two cleaning plates 10 in an eight-shaped shape, and then the two cleaning plates 10 are used to complete the cleaning of the surface of the scraping plate 8. Through the above structure, when cleaning the outer surface of the scraping plate 8, the locking component can be unlocked and the cleaning can be automatically completed during the process of retracting the scraping plate 8, avoiding the outer surface of the scraping plate 8 to adhere to a lot of residue, causing the surface to be too uneven, and then causing the protrusions in the scraping process to scrape the residue to both sides, resulting in reduced efficiency.

When the sliding block 3 moves, it will simultaneously drive the push rod 4 to move. When the push rod 4 moves, the U-shaped plate 5 drives the rotating shaft 6 to move, and then the rotating shaft 6 drives the connecting sleeve 7 and the scraping plate 8 to move. After the scraping plate 8 moves, it contacts the collecting component. Since the rotating shaft 6 can rotate at this time, the scraping plate 8 is squeezed to rotate around the rotating shaft 6. After the scraping plate 8 rotates, it presents The push rod 4 continues to move so that the scraping plate 8 contacts the two cleaning plates 10 in an eight-shaped shape, and then the two cleaning plates 10 are used to clean the surface of the scraping plate 8. The locking rod 13 is driven to move by the electric push rod 12. After the movement, the locking rod 13 disengages from the locking plate 14, thereby completing the unlocking of the rotating shaft 6.
