Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting, and specifically to a desulfurization slag remover with self-cleaning function. Background Technology

[0002] During the steelmaking process, sulfur easily forms low-melting-point sulfides in steel, causing "hot brittleness" during hot working, which reduces the strength, toughness, and weldability of the steel. For example, when steel parts with excessive sulfur content are deformed at high temperatures, the melting of sulfides can cause grain boundary cracking, affecting the safety of the components. Desulfurization can remove sulfur from molten iron, thereby ensuring the quality of molten steel and optimizing the smelting process. However, desulfurization will produce a large amount of sulfur-containing slag, which needs to be cleaned up in a timely manner.

[0003] However, during the use of existing desulfurization slag removers, desulfurization slag easily adheres to the slag remover shovel. Due to the high temperature of the desulfurization slag, it is not convenient for operators to clean the slag remover shovel. This leads to the continuous accumulation of slag, which in turn affects the operating accuracy and working efficiency of the slag remover. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of desulfurization slag adhering to the slag scraper and being difficult to clean in the existing technology, and to provide a desulfurization slag scraper with a self-cleaning function. This desulfurization slag scraper has a self-cleaning function and can clean the sulfur slag adhering to the slag scraper in a timely manner as needed, so as to ensure the working efficiency of the slag scraper.

[0005] To achieve the above objectives, this utility model provides a desulfurization slag remover with a self-cleaning function. The desulfurization slag remover includes a base, on which a support column is mounted via a rotating mechanism. The rotation center of the support column is parallel to the vertical direction. A support rod is hinged to the support column, and the support rod is connected to a pitch drive component that drives it to pitch. The support rod is hollow inside, and a slag remover rod is mounted inside its cavity via a moving mechanism. A slag remover shovel is mounted at one end of the slag remover rod via a vibration mechanism, which causes the slag remover shovel to vibrate.

[0006] Using the above technical solution, the slag-removing shovel can be rotated as needed via a rotating mechanism to adjust it to the required slag-removing angle. The support rod is driven downward by a pitch drive to insert the slag-removing shovel into the required slag-removing position. The slag-removing shovel is then moved by a moving mechanism to push the sulfur slag to other locations. When a large amount of sulfur slag adheres to the slag-removing shovel, a vibration mechanism is activated to vibrate and shake off the sulfur slag, thus keeping the slag-removing shovel in a relatively clean state and improving its working efficiency.

[0007] Preferably, the vibration mechanism includes a first connecting plate, a second connecting plate, and a drive assembly. The first connecting plate is mounted on one end of the slag-removing rod, and the second connecting plate is mounted on the handle of the slag-removing shovel. The second connecting plate and the first connecting plate are slidably connected, and the drive assembly is connected to the second connecting plate. With this structure, the drive assembly drives the slag-removing shovel to perform rapid reciprocating vibration, effectively shaking off the adhering sulfur slag and keeping it clean.

[0008] Preferably, a guide seat is fixedly installed on the first connecting plate, and a guide hole is opened in the guide seat; a guide rod is fixedly installed on the second connecting plate, and the guide rod is inserted into the corresponding guide hole. The drive assembly includes a first motor with a cam mounted on its output shaft. A support block with a hole is mounted on the slag-removing rod, and a drive rod is movably inserted into the hole of the support block. The drive rod is parallel to the slag-removing rod, with one end passing through the first connecting plate and connecting to the second connecting plate. A spring is sleeved on the drive rod between the support block and the first connecting plate, with one end fixedly connected to the drive rod and the other end fixedly connected to the first connecting plate. A vibration block is mounted on the other end of the drive rod, and the cam drives the vibration block to move. With this structure, as the cam rotates, it pushes the drive rod to move in a preset direction. During this process, the spring is compressed and deformed. When the cam rotates to a certain position, the elastic potential energy of the spring is released, causing the drive rod to return to its original position. This reciprocating motion causes the slag-removing shovel to vibrate repeatedly.

[0009] Preferably, the moving mechanism includes a rack fixedly mounted on the slag-removing rod, and a second motor mounted on the support rod. The output shaft of the second motor extends movably into a cavity within the support rod and is fitted with a gear, which meshes with the rack. This structure, through the engagement of the rack and pinion, drives the slag-removing rod to move, thereby pushing the sulfur slag to a preset position.

[0010] Preferably, the pitch drive is an electric telescopic rod, one end of which is hinged to the support column and the other end of which is hinged to the support rod.

[0011] Preferably, the rotating mechanism includes a third motor, which is fixedly mounted on the base. The output shaft of the third motor movably passes through the base and is connected to a turntable. The support column is fixedly mounted on the turntable.

[0012] Preferably, a limiting plate is installed at the end of the slag-scraping rod corresponding to the rack, and the area of ​​the limiting plate is larger than the area of ​​the internal cavity of the support rod. With this structure, when the slag-scraping rod is moved so that the limiting plate abuts against the end of the support rod, it can limit the slag-scraping rod and prevent it from falling off the support rod.

[0013] Preferably, the support block is U-shaped, with an internal U-shaped groove forming a hole through which the drive rod passes. This structure facilitates direct insertion of the drive rod from the side notch of the U-shaped groove, enabling rapid assembly.

[0014] Preferably, the first motor is installed on the slag-removing rod on one side of the support rod, and the second motor is installed on the side wall of the other side of the support rod. This structure, by arranging the two motors on opposite sides of the support rod, helps to improve the balance of the support rod and enhances the stability of its operation.

[0015] Preferably, the support column has a movable hole, and the support rod is movably inserted into the movable hole and hinged to the support column. This structure allows for a larger movable hole, which provides some clearance for the movement of the support rod and avoids unnecessary collisions between the support rod and the support column.

[0016] Through the above technical solution, the rotating mechanism can adjust the slag-removing shovel to the required angle for slag removal. The pitch drive drives the support rod downward to insert the slag-removing shovel into the required slag-removing position. The moving mechanism then drives the slag-removing shovel to move, thus pushing the sulfur slag to other locations. When a large amount of sulfur slag adheres to the slag-removing shovel, the vibration mechanism is activated to make the slag-removing shovel vibrate back and forth, thereby shaking off the sulfur slag and keeping the slag-removing shovel in a certain clean state, which is conducive to improving its working efficiency.

[0025] like Figure 1 , 2 As shown in Figure 5, in some embodiments, a desulfurization slag remover with a self-cleaning function is provided. The desulfurization slag remover includes a base 1, on which a support column 101 is mounted via a rotating mechanism. The rotation center of the support column 101 is parallel to the vertical direction. A support rod 102 is hinged to the support column 101. The support rod 102 is connected to a pitch drive 311 that drives it to pitch. The support rod 102 is hollow inside, and a slag remover 103 is mounted in its cavity via a moving mechanism. The moving direction of the slag remover 103 is parallel to the support rod 102. A slag remover shovel 104 is mounted at one end of the slag remover 103 via a vibration mechanism 2. The vibration mechanism 2 is used to vibrate the slag remover shovel 104.

[0026] In some embodiments, such as Figure 7 As shown, the rotating mechanism includes a third motor 316, which is fixedly mounted on the lower surface of the base 1. The output shaft 317 of the third motor 316 moves upward through the base 1 and is connected to a turntable 105. The support column 101 is fixedly mounted on the turntable 105.

[0027] In some embodiments, such as Figure 6 As shown, the pitch drive 311 is an electric telescopic rod, one end of which is hinged to the support column 101 and the other end is hinged to the support rod 102.

[0028] In some embodiments, the support column 101 has a movable hole 106, and the support rod 102 is movably inserted into the movable hole 106 and hinged to the support column 101.

[0029] In some embodiments, such as Figure 6As shown, the moving mechanism includes a rack 315 fixedly mounted on the slag-removing rod 103, a second motor 312 mounted on the support rod 102, and a gear 314 mounted on the output shaft 313 of the second motor 312 after it extends movably into the cavity inside the support rod 102. The gear 314 meshes with the rack 315.

[0030] In some embodiments, such as Figure 1 As shown, a limiting plate 318 is installed at the end of the slag-removing rod 103 corresponding to the rack 315. The area of ​​the limiting plate 318 is larger than the area of ​​the cavity inside the support rod 102, so that when the gear 314 drives the rack 315 to move to the end limit position, the limiting plate 318 abuts against the end of the support rod 102, thus playing a limiting role.

[0031] like Figure 3 and Figure 4 As shown, the vibration mechanism 2 includes a first connecting plate 212, a second connecting plate 211, and a drive assembly. The first connecting plate 212 is fixedly installed at one end of the slag-scraping rod 103, and the second connecting plate 211 is fixedly installed on the handle of the slag-scraping shovel 104. The second connecting plate 211 and the first connecting plate 212 are slidably connected, and the drive assembly is connected to the second connecting plate 211.

[0032] In some embodiments, a guide seat 220 is fixedly installed on the first connecting plate 212, and a guide hole is provided in the guide seat 220. A guide rod 221 is fixedly installed on the second connecting plate 211, and the guide rod 221 is inserted into the corresponding guide hole. The drive assembly includes a first motor 213, on which a cam 215 is mounted. A support block 216 with a hole is mounted on the slag-removing rod 103. A drive rod 217 is movably inserted into the hole of the support block 216. The drive rod 217 is parallel to the slag-removing rod 103. One end of the drive rod 217 movably passes through the first connecting plate 212 and is fixedly connected to the second connecting plate 211. A spring 219 is sleeved on the drive rod 217 between the support block 216 and the first connecting plate 212. One end of the spring 219 is fixedly connected to the drive rod 217, and the other end is fixedly connected to the first connecting plate 212. A vibration block 218 is mounted on the other end of the drive rod 217. The cam 215 is used to drive the vibration block 218 to move.

[0033] In some embodiments, the guide rod 221 is L-shaped, with its short arm fixedly connected to the second connecting plate 211 and its long arm movably inserted into the guide hole of the guide seat 220.

[0034] The support block 216 is U-shaped, and its internal U-shaped groove forms a hole through which the drive rod 217 passes. The surface of the vibrating block 218 that is in close contact with the cam 215 is an arc-shaped surface.

[0035] like Figure 3 As shown, a spring fixing plate 222 is installed on the drive rod 217 between the support block 216 and the first connecting plate 212. One end of the spring 219 is fixedly connected to the first connecting plate 212, and the other end is fixedly connected to the spring fixing plate 222. The spring fixing plate 222 is close to the support block 216.

[0036] In some implementations, such as Figure 2 As shown, the first motor 213 is installed on the slag-removing rod 103 on one side of the support rod 102, and the second motor 312 is installed on the side wall on the other side of the support rod 102.

[0037] In this application, the support rod 102, the slag-removing rod 103, the pitch drive component 311, the moving mechanism, and the slag-removing shovel 104 together constitute the slag-removing mechanism 3. The slag-removing mechanism 3 is supported by the base 1, and the slag-removing mechanism 3 can complete the slag-removing operation. When sulfur slag adheres to the slag-removing shovel 104, it can be shaken off by the vibration mechanism 2. The specific working principle of the slag-removing machine provided in this application is as follows: As needed, the third motor 316 is activated to rotate the support column 101, thereby rotating the slag scraper 104 to the position where slag needs to be scraped. Then, the electric telescopic rod is activated to move the support rod 102 downward, so that the slag scraper 104 is inserted into the sulfur slag pile. Then, the second motor 312 is activated, and the rotation of the gear 314 drives the rack 315 to move, thereby pushing the slag scraper 103 to move, thereby pushing a certain amount of sulfur slag away from the sulfur slag pile, achieving the purpose of cleaning the sulfur slag. When a lot of sulfur slag adheres to the slag scraper 104, the first motor 213 of the vibration mechanism 2 is activated, and the rotation of the cam 215 pushes the drive rod 217 to move in a preset direction, thereby pushing the slag scraper 104 to move (e.g., Figure 3 (On the left side of the image), the spring 219 is compressed. When the cam 215 rotates to a certain position, the compressed spring 219 drives the drive rod 217 to reset. This process repeats, thereby achieving the reciprocating vibration of the slag scraper 104 to shake off the sulfur slag adhering to it.
