Description

Technical Field

[0001] This utility model relates to the field of slag grabbing technology, specifically a high-efficiency slag grabbing machine for electric furnaces used in silicon-manganese alloys. Background Technology

[0002] The foundry industry commonly uses electric furnaces to heat, adjust the composition, and purify silicon-manganese alloys. During the silicon-manganese alloying process, impurities in the silicon-manganese alloy are separated from the alloy after heating to form slag.

[0003] The inventors discovered that at least the following problems remain unsolved in existing technologies: valuable ferrosilicon manganese alloy liquid often remains in the slag. Traditional slag grabbers only have a single drain hole in their gripper, causing the slag to accumulate and making it difficult to effectively recover the residual ferrosilicon manganese alloy liquid, resulting in a waste of resources.

[0004] Therefore, we propose a high-efficiency slag grabber for electric furnaces used in silicon-manganese alloys. After grabbing the slag, it can automatically stir the slag and effectively recover the residual silicon-manganese alloy liquid in the slag. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency slag grabber for electric furnaces used in silicon-manganese alloys, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency electric furnace slag grabber for silicon-manganese alloys, comprising an installation block and two sets of grabbers. Rotation grooves are symmetrically opened in the middle of the bottom ends on both sides of the installation block. A drive rod is horizontally welded to the top of each grabber. A lead screw is vertically rotatably connected to the middle of the bottom side of the installation block via a bearing. A stirring rod is fixedly connected to the bottom end of the lead screw. The utility model also includes a drive mechanism for driving the grabbers and stirring rod to rotate.

[0007] As an optional solution to the technical solution of this application, the driving mechanism includes a servo motor, a groove is provided in the middle of the mounting block, a slide plate is slidably connected inside the groove, a connecting groove is vertically provided in the middle of the slide plate, the external thread on the outside of the lead screw is helically connected to the connecting groove, and the shaft end of the servo motor is fixedly connected to the top end of the lead screw.

[0008] As an optional solution to the technical solution of this application, the servo motor is fixedly connected above the slide groove, and a textureless area is provided on the outer side of the end of the lead screw near the servo motor, the textureless area matching the size of the slide plate.

[0009] As an optional solution to the technical solution of this application, a first rack is vertically welded to both ends of the lower surface of the slide plate, and an arc-shaped second rack is welded to the outer side of the drive rod, wherein the first rack meshes with the second rack.

[0010] As an optional solution to the technical solution of this application, the stirring rod is matched with the size of the gripper, and the bottom inner wall of the gripper is uniformly provided with drainage holes.

[0011] As an optional solution to the technical solution of this application, the two ends of the drive rod are rotatably connected to the inner walls of the front and rear sides of the rotating groove through bearings, and the two sets of grippers are symmetrically arranged.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: controlling the servo motor to work can drive the lead screw to rotate, and the slide can push the two sets of first racks to move downwards. The second rack can drive the drive rod to rotate, thereby driving the two sets of grippers to rotate relative to each other, realizing the grabbing of slag. When the slide moves to the top of the trough, the slide stops moving because the top of the lead screw is provided with a textureless area. The servo motor continues to work, which can drive the stirring rod at the bottom of the lead screw to rotate, thereby stirring the slag inside the two sets of grippers. The liquid ferrosilicon alloy remaining on the surface of the slag can be discharged through the drain hole, saving resources. Attached Figure Description

[0017] Please see Figures 1-2This utility model provides a technical solution: a high-efficiency electric furnace slag grabber for silicon-manganese alloys, comprising a mounting block 1 and two sets of grabs 13. The mounting block 1 has symmetrically arranged rotating grooves 11 at the center of its bottom sides. A drive rod 12 is horizontally welded to the top of each grab 13. The two ends of the drive rod 12 are rotatably connected to the inner walls of the rotating grooves 11 on both sides via bearings. A lead screw 21 is vertically rotatably connected to the center of the bottom side of the mounting block 1 via bearings. The model also includes a drive mechanism for driving the grabs 13 and the stirring rod 23 to rotate, the drive mechanism including a servo motor 25. The mounting block 1 has a groove 14 in the middle, and a slide plate 15 is slidably connected inside the groove 14. A connecting groove 2 is vertically opened through the middle of the slide plate 15. The external thread of the lead screw 21 is spirally connected to the connecting groove 2. The shaft end of the servo motor 25 is fixedly connected to the top end of the lead screw 21. The servo motor 25 is fixedly connected above the groove 14. The two ends of the lower surface of the slide plate 15 are vertically welded with a first rack 16. The outer side of the drive rod 12 is welded with an arc-shaped second rack 17. The first rack 16 and the second rack 17 mesh. The two sets of grippers 13 are symmetrically arranged.

[0018] In this technical solution, the telescopic mechanism at the top of the mounting block 1 pushes the two sets of grippers 13 separated on the bottom side of the mounting block 1 into the electric furnace. The corresponding controller controls the servo motor 25 to work, which can drive the lead screw 21 to rotate. The lead screw 21 is spirally connected to the connecting groove 2 in the middle of the slide plate 15 through the external thread on the outside of the lead screw 21. The rotation direction of the lead screw 21 is controlled, which can drive the slide plate 15 to move up and down in the slide groove 14. When the slide plate 15 moves up to the top of the slide groove 14, the slide plate 15 can push the two sets of first racks 16 to move down. The second rack 17 can drive the drive rod 12 to rotate, thereby driving the two sets of grippers 13 to rotate relative to each other and fit together, which can realize the slag grabbing operation.

[0019] In this embodiment, a textureless area 22 is provided on the outer side of the end of the lead screw 21 near the servo motor 25, and the textureless area 22 matches the size of the slide plate 15.

[0020] In this technical solution, when the slide plate 15 moves to the top of the slide groove 14, the top of the lead screw 21 is provided with a textureless area 22, which prevents the slide plate 15 from moving further. At the same time, the slide plate 15 does not interfere with the normal rotation of the lead screw 21.

[0021] In this embodiment, a stirring rod 23 is fixedly connected to the bottom end of the lead screw 21. The stirring rod 23 is matched with the size of the gripper 13. Drainage holes 24 are evenly opened on the inner wall of the bottom end of the gripper 13.

[0022] In this technical solution, the servo motor 25 drives the lead screw 21 to rotate, which in turn drives the stirring rod 23 at the bottom of the lead screw 21 to rotate, thereby stirring the slag inside the two sets of grippers 13. The liquid silicon-manganese alloy remaining on the surface of the slag can be discharged through the drain hole 24, saving resources.

[0023] When using a high-efficiency electric furnace slag grabber for silicon-manganese alloys, the telescopic mechanism at the top of the mounting block 1 pushes the two sets of grabbers 13, separated on the bottom side of the mounting block 1, into the electric furnace. The corresponding controller controls the servo motor 25, which drives the lead screw 21 to rotate. The lead screw 21 is spirally connected to the connecting groove 2 in the middle of the slide plate 15 via its external thread, controlling the rotation direction of the lead screw 21. This allows the slide plate 15 to move up and down within the slide groove 14. When the slide plate 15 moves upward to the top of the slide groove 14, it pushes the two sets of first racks 16 downward, which in turn move downward via the second rack 17. The drive rod 12 rotates, causing the two grippers 13 to rotate relative to each other and fit together, enabling the slag to be gripped. When the slide plate 15 moves to the top of the chute 14, the slide plate 15 cannot be driven to move further because the top of the lead screw 21 has a textureless area 22. At the same time, the slide plate 15 does not interfere with the normal rotation of the lead screw 21. While the servo motor 25 drives the lead screw 21 to rotate, it can also drive the stirring rod 23 at the bottom of the lead screw 21 to rotate, thereby stirring the slag inside the two grippers 13. The liquid ferrosilicon alloy remaining on the surface of the slag can be discharged through the drain hole 24, saving resources.
