Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a hydraulic electromagnetic stirrer lift. Background Technology

[0002] The hydraulic electromagnetic stirrer lift is a specialized industrial piece of equipment that combines electromagnetic stirring technology with a hydraulic lifting system. It is primarily used in the smelting process of non-ferrous metals to achieve homogenization of melt composition and temperature, thereby significantly improving product quality and production efficiency.

[0003] Chinese utility model patent CN222393379U discloses an electromagnetic stirring device for molten metal: It includes a base, an electromagnetic stirrer on the top of the base, and an adjustment assembly on the base wall for driving the displacement of the electromagnetic stirrer. The adjustment assembly includes a load-bearing plate, a vertical plate, a lead screw, a limiting rod, and a connecting plate. The load-bearing plate is slidably connected to the base, the vertical plate is fixedly connected to the load-bearing plate, the lead screw is rotatably connected to the vertical plate, and the limiting rod is fixedly connected to the vertical plate. The electromagnetic stirrer causes the molten metal in the crucible furnace to flow from the center to both sides, promoting the mutual compression and convection effect between the inner wall and the center of the crucible furnace, ensuring the uniformity of the molten metal mixing and higher efficiency. The electromagnetic stirrer moves horizontally and vertically, continuously changing the stirring position, further improving the mixing effect of the liquid in the crucible furnace cavity.

[0004] However, existing technologies still have shortcomings: The above setup uses a mechanical lifting mechanism to adjust the height and angle of the electromagnetic stirrer. First, the electromagnetic stirrer can only rotate at the bottom when it rotates around the base, and cannot rotate after it rises, affecting the uniformity of processing. Second, the lead screw of the mechanical lifting mechanism is prone to thermal deformation in high-temperature environments, which can lead to jamming or loss of precision. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a hydraulic electromagnetic stirrer lift to address the problem in the prior art where mechanical lifting mechanisms, used to adjust the height and angle of the electromagnetic stirrer, can only rotate at the bottom when the stirrer is rotating around the base, and cannot rotate after rising, meaning that angle adjustment is impossible after rising, thus affecting the uniformity of processing.

[0006] To achieve the above objectives, this utility model proposes a hydraulic electromagnetic stirrer lift, comprising a base, a crucible furnace body for loading molten metal is fixedly mounted on the base, a small amount of interfering fluid is fixedly mounted inside the crucible furnace body, an electromagnetic stirrer is adjustablely mounted on the outside of the crucible furnace body, an L-shaped side plate is fixedly mounted on the side of the base, a hydraulic cylinder is fixedly mounted on the L-shaped side plate, a load-bearing plate is fixedly connected to the output shaft of the hydraulic cylinder, a limit ring is freely mounted on the base, a connecting frame is fixedly mounted on the limit ring, the load-bearing plate is fixedly connected to the connecting frame and the limit ring, a mounting plate is mounted on the limit ring, and the electromagnetic stirrer is fixedly mounted on the mounting plate.

[0007] As a further embodiment of this utility model: the turbulent fluid has a curved panel-like structure, and four turbulent fluids are arranged inside the crucible furnace.

[0008] As a further embodiment of this utility model, the load-bearing plate is slidably connected to the L-shaped side plate.

[0009] As a further embodiment of this utility model: a second guide groove is provided on the limiting ring, and a slider is fixedly provided at the lower end of the mounting plate, the slider being slidably embedded in the second guide groove.

[0010] As a further embodiment of this utility model, a telescopic rod is fixedly installed below the mounting plate.

[0011] As a further embodiment of this utility model, the lower end of the telescopic rod is slidably disposed within the base.

[0012] As a further embodiment of this utility model: a limiting frame is fixedly provided inside the base, and the lower end of the telescopic rod is slidably embedded in the limiting frame.

[0013] As a further embodiment of this utility model, the base is provided with an annular first guide groove that matches the telescopic rod.

[0014] As a further embodiment of this utility model: a guide gear ring is rotatably mounted on the base, a servo motor is fixedly mounted on the side of the base, the output shaft of the servo motor is fixedly connected to a drive wheel, the drive wheel meshes with the guide gear ring, a through groove is provided on the guide gear ring, and the telescopic rod passes through the through groove and is fixedly connected to the mounting plate.

[0015] As a further embodiment of this utility model: the inner diameter of the through groove is consistent with the outer diameter of the telescopic end of the telescopic rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a hydraulic cylinder to drive the movement of the electromagnetic stirrer, starting the hydraulic cylinder pushes the load-bearing plate to move upward, thereby driving the limit ring to move upward. The upward movement of the limit ring drives the mounting plate to move upward, pulling the telescopic rod to extend and retract. The upward movement of the mounting plate drives the electromagnetic stirrer to move upward, which can realize the processing of the electromagnetic stirrer at different heights of the crucible furnace body.

[0017] 2. By setting a motor to drive the circumferential movement of the electromagnetic stirrer, and by driving the limit ring to move up and down through the hydraulic cylinder, the motor drives the mounting plate to rotate on the limit ring. That is, the circumferential movement and the upward movement will not interfere with each other. The servo motor is started to drive the drive wheel to rotate, which drives the guide gear ring to rotate. The guide gear ring drives the telescopic rod to rotate, thereby driving the mounting plate to rotate on the limit ring. This can realize the adjustment of the circumferential position of the electromagnetic stirrer on the outer ring of the crucible furnace. With the lifting structure, it can realize all-round processing. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-4As shown, the hydraulic electromagnetic stirrer lift includes a base 1, on which a crucible furnace body 2 for loading molten metal is fixedly mounted. Several turbulent fluids 3 are fixedly mounted inside the crucible furnace body 2. An electromagnetic stirrer 9 is adjustablely mounted on the outside of the crucible furnace body 2. The turbulent fluids 3 have a curved plate-like structure and can cut and guide the molten metal. At least four turbulent fluids 3 are arranged inside the crucible furnace body 2. The multiple turbulent fluids 3 divide the chamber of the crucible furnace body 2. When the electromagnetic stirrer 9 moves around the crucible furnace body 2, the liquid will flow. The multiple turbulent fluids 3 continuously cut and divert the liquid, promoting mutual compression and convection between the liquids, thereby promoting the stirring and mixing of the liquid. The electromagnetic stirrer 9 can move circumferentially and vertically around the crucible furnace body 2. Specifically, a guide gear ring 10 is rotatably mounted on the base 1, a servo motor 12 is fixedly mounted on the side of the base 1, and the output shaft of the servo motor 12 is fixedly connected to a drive wheel 11. The drive wheel 11 meshes with the guide gear ring 10. An L-shaped side plate 4 is fixedly mounted on the side of the base 1, and a hydraulic cylinder 5 is fixedly mounted on the L-shaped side plate 4. The output shaft of the hydraulic cylinder 5 is fixedly connected to a load-bearing plate 18, and the load-bearing plate 18 slides with the L-shaped side plate 4. Next, a limit ring 7 is freely disposed on the base 1, and a connecting frame 6 is fixedly disposed on the limit ring 7. The load-bearing plate 18 is fixedly connected to the connecting frame 6 and the limit ring 7. A mounting plate 8 is slidably disposed on the limit ring 7. Specifically, a second guide groove 17 is opened on the limit ring 7, and a slider is fixedly disposed at the lower end of the mounting plate 8. The slider is embedded and slidably disposed in the second guide groove 17. Several mounting plates 8 are provided to balance the movement of the limit ring 7. A telescopic rod 13 is fixedly disposed below the mounting plate 8. A load-bearing plate 18 is fixedly disposed inside the base 1. A limit frame 14 is provided, and the lower end of the telescopic rod 13 is slidably embedded in the limit frame 14. An annular first guide groove 15 is provided on the base 1 to facilitate the movement of the telescopic rod 13. A through groove 16 is provided on the guide toothed ring 10, the inner diameter of which is the same as the outer diameter of the telescopic end of the telescopic rod 13. The telescopic rod 13 passes through the through groove 16 and is fixedly connected to the mounting plate 8. Activating the hydraulic cylinder 5 pushes the load-bearing plate 18 upward, thereby causing the limit ring 7 to move upward. The upward movement of the limit ring 7 causes the mounting plate 8 to move upward, pulling the telescopic rod 13 to extend and retract. The upward movement of the mounting plate 8 causes the electromagnetic stirrer 9 to move upward, enabling the electromagnetic stirrer 9 to process at different heights in the crucible furnace body 2. The servo motor 12 is started to drive the drive wheel 11 to rotate, which in turn drives the guide gear ring 10 to rotate. The guide gear ring 10 drives the telescopic rod 13 to rotate, which in turn drives the mounting plate 8 to rotate on the limit ring 7. This allows the electromagnetic stirrer 9 to be adjusted in the circumferential position on the outer ring of the crucible furnace body 2. Together with the turbulent fluid 3, this continuously cuts and diverts the liquid in the crucible furnace body 2, ensuring thorough mixing of the liquid.

[0022] Working principle: The molten metal to be processed is loaded into the crucible furnace body 2. The electromagnetic stirrer 9 is started, and the servo motor 12 drives the drive wheel 11 to rotate, which in turn drives the guide gear ring 10 to rotate. The guide gear ring 10 drives the telescopic rod 13 to rotate, which in turn drives the mounting plate 8 to rotate on the limiting ring 7. This allows the electromagnetic stirrer 9 to be adjusted in the circumferential position of the outer ring of the crucible furnace body 2. When the electromagnetic stirrer 9 revolves around the crucible furnace body 2, the liquid will flow. Multiple turbulent fluids 3 continuously cut and divert the liquid, promoting mutual compression and convection between the liquids, thereby promoting the mixing of the liquid. The hydraulic cylinder 5 is started, pushing the load-bearing plate 18 upward, which in turn drives the limiting ring 7 upward. The upward movement of the limiting ring 7 drives the mounting plate 8 upward, pulling the telescopic rod 13 to extend and retract. The upward movement of the mounting plate 8 drives the electromagnetic stirrer 9 upward, enabling the electromagnetic stirrer 9 to process at different heights in the crucible furnace body 2.
