Description

Technical Field

[0001] The utility model relates to the technical field of spheroidal graphite cast iron smelting, in particular to a slag scraping structure for smelting spheroidal graphite cast iron. Background Art

[0002] When the ductile iron is recycled and re-smelted, a furnace is used to hold the cast iron, and then the furnace is heated to melt the cast iron into molten iron in the furnace. After the molten iron inside the furnace is poured out, some molten iron may remain inside the furnace. This part of the molten iron will form solid slag after condensation and adhere to the inner wall of the furnace. When the furnace is scraped to remove the slag, the surface of the inner wall of the furnace may adhere to the slag, causing the slag to be scraped off together with part of the furnace surface, causing damage to the furnace body, which is inconvenient. In addition, furnace slag removal is generally mostly manual. For safety reasons, most of the cleaning is done after the furnace has cooled down, which is inconvenient. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In an embodiment of the utility model, a slag scraping structure for ductile iron smelting includes a furnace body 100, support plates 110 are arranged on opposite sides of the furnace body 100, and the tops of the two support plates 110 are rotatably connected with rotating rods 120, and the adjacent ends of the two rotating rods 120 are fixedly connected to the outer wall of the furnace body 100, a scraping mechanism 200 is arranged above the furnace body 100, and the scraping mechanism 200 is equipped with a driving mechanism 400, and the two rotating rods 120 are arranged at opposite ends thereof. The moving mechanism 300 is far away from the furnace body 100;

[0022] The scraping mechanism 200 includes two slides 210, and the bottom ends of the two slides 210 are provided with a sleeve hole 211, the inner walls of the two sleeve holes 211 are respectively slidably connected to the outer walls of the two rotating rods 120, a slide rail 220 is arranged above the furnace body 100, and the top ends of the two slides 210 are slidably connected to the inside of the slide rail 220, the top surface of the slide rail 220 is rotatably connected with a rotating shaft 231, and the outer wall of the rotating shaft 231 is fixedly connected with multiple scrapers 232, two shells 240 are arranged inside the furnace body 100, and the top ends of the two shells 240 are fixedly connected with sliders 241, the adjacent sides of the two slides 210 are provided with slide grooves 212, and the two sliders 241 are respectively slidably connected to the inside of the two slide grooves 212.

[0023] Specifically, the two shells 240 can be inserted into the furnace body 100 after closing, so that the outer wall of the shell 240 is close to the inner wall of the furnace body 100, and the cast iron is placed in the two shells 240 by putting it into the furnace body 100, and then the heat is transferred to the shells 240 by heating the furnace body 100 to melt the cast iron, and then the user can rotate the two rotating rods 120 to rotate and tilt the furnace body 100, so as to pour out the molten iron in the two shells 240, and then the two shells 240 can be opened while the molten iron in the shells 240 is not cooled. 0 slides to make multiple scrapers 232 enter the inside of the two shells 240, and then rotates the rotating shaft 231 to make multiple scrapers 232 scrape the inside of the two shells 240 to scrape out excess molten iron.

At the same time, the scraper 232 can be used to scrape the residual molten iron in the shell 240, which is convenient for users.

[0024] Embodiment 1

[0026] In this embodiment, by starting the power motor, the rotating shaft 231 can be driven to rotate, thereby rotating multiple scrapers 232, so that the scrapers 232 scrape the residual molten iron in the shell 240, which is convenient for users to use, and the swing cylinder can drive the rotating rod 120 and the furnace body 100 to rotate and tilt synchronously, so that the furnace body 100 drives its inner shell 240 to tilt and dump the molten iron, which is convenient for users to use.

[0027] like Figure 2-4As shown, in this embodiment, the driving mechanism 400 includes a moving frame 450, and the moving frame 450 is slidably sleeved with the outer wall of the slide rail 220, and the screw rods 410 are rotatably connected between the top and bottom ends of the two slide grooves 212, and the top surfaces of the two sliders 241 are provided with threaded holes whose inner walls are screwed with the outer walls of the adjacent screw rods 410, and the top surface of the slide rail 220 is provided with two guide grooves 221, and the top ends of the two screw rods 410 respectively penetrate the two guide grooves 221, and the top ends of the two screw rods 410 are fixedly sleeved with gears 411, and the outer walls of the two gears 411 are rotatably sleeved with a toothed belt 412, and the top surface of the moving frame 450 is fixedly connected with a driving box 451, and the driving box 451 is fixedly connected with the driving box 451. A driving motor is arranged inside the box 451, and the motor shaft of the driving motor passes through the movable frame 450 and is fixedly connected to the top of the adjacent screw rod 410, a connecting plate 430 is fixedly connected to the top surface of the slide rail 220, and a top plate 440 is arranged on one side of the connecting plate 430, a plurality of rebound springs 441 are fixedly connected between one side of the top plate 440 and one side of the connecting plate 430, and the other side of the top plate 440 is in contact with the outer side wall of the toothed belt 412, two limiting rollers 420 are rotatably connected to the top surface of the slide rail 220, and the two limiting rollers 420 are both located inside the toothed belt 412, and the two limiting rollers 420 are in contact with the inner side wall of the toothed belt 412, and the length of the slide groove 212 is greater than the length of the shell 240.

[0028] During specific implementation, the driving motor is started to drive the screw 410 connected thereto to rotate, and the toothed belt 412 is used to drive the relatively arranged screw 410 to rotate synchronously, so that the screw 410 drives the shell 240 to move synchronously, so that the shell 240 is moved out of the furnace body 100 or embedded in the furnace body 100. When the two shells 240 are moved out of the furnace body 100, the user can start the moving mechanism 300 to drive the slide plate 210 and the shell 240 to slide back and forth along the rotating rod 120, so that the shell 240 is scraped by multiple scrapers 232 to remove the residual molten iron inside, and the residual molten iron in the shell 240 can be more easily discharged by the gap generated by the separation of the shell 240 and the vibration generated by the collision of the shell 240 when the shell 240 is closed.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, the adjacent housing 240 is driven to move by the electric push rod 320 .

[0032] During specific implementation, when the swing cylinder drives the rotating rod 120 and the furnace body 100 to dump the molten iron, the electric push rods 320 and the two slides 210 on the two moving mechanisms 300 rotate and tilt synchronously with the adjacent rotating rods 120, and the slide rails 220 rotate and tilt synchronously with the two 210. After the molten iron is poured, the power motor and the drive motor are started to make the screw 410 rotate synchronously and drive the shell 240 to move out of the furnace body 100. At the same time, the rotating shaft 231 drives multiple scrapers 232 to scrape the inner wall of the shell 240 to scrape the remaining molten iron out of the shell 240. At the same time, the electric push rod 320 is started to drive the slide 210 and the adjacent shell 240 to move back and forth, so that the shell 240 moves away from each other to generate a gap, and when the shell 240 approaches each other and closes, they collide with each other to generate vibration, so that the residual molten iron in the shell 240 is easier to flow out of the shell 240 from the gap where the shell 240 is separated.
