Description

Technical Field

[0001] This utility model relates to the field of medium-frequency induction furnace technology, specifically to a feeding device for a medium-frequency induction furnace. Background Technology

[0002] A medium-frequency induction furnace is a device that uses the principle of electromagnetic induction to heat or melt metal, with an operating frequency range of 150–10000 Hz. By converting industrial frequency alternating current (50 Hz) into medium-frequency alternating current, an alternating magnetic field is generated in the induction coil, causing eddy currents inside the metal and generating heat, thereby achieving rapid heating or melting. Currently, medium-frequency induction furnaces require a feeding device for material feeding. Existing feeding devices are usually not convenient for pre-crushing scrap iron materials, resulting in slow melting efficiency and low processing efficiency after the scrap iron materials are put into the medium-frequency induction furnace.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a feeding device for a medium-frequency induction furnace, including a material rack 1 and a feeding box 3. The inner cavity of the material rack 1 has sliding grooves 5 on both side walls. An adjustment component 6 is installed on the material rack 1. A crushing component 4 is installed inside the feeding box 3. Rollers 2 are fixedly installed at the bottom of the material rack 1. The crushing component 4 can pre-crush the scrap iron, processing it into spherical or granular shapes, reducing the material volume and increasing the material surface area. This results in more uniform melting and heating of the scrap iron after it is fed into the medium-frequency induction furnace, thereby accelerating the melting speed and improving production efficiency. With the adjustment component 6, the height of the feeding box 3 can be adjusted, facilitating the adjustment of the feeding height of the medium-frequency induction furnace, improving flexibility, and facilitating feeding.

[0022] The crushing assembly 4 includes a support plate 41 fixedly installed on one side of the feed box 3. A connecting rod 42 is rotatably connected inside the support plate 41. A drive motor 43 is fixedly installed on one side of the support plate 41. The output shaft of the drive motor 43 is fixedly connected to the connecting rod 42. Multiple active bevel gears 44 are fixedly installed on the outer wall of the connecting rod 42. Multiple crushing rollers 45 are rotatably connected inside the feed box 3. A driven bevel gear 46 is fixedly installed on one side of each crushing roller 45. The drive motor 43 drives the connecting rod 42 to rotate, which in turn drives the active bevel gears 44 to rotate. The driven bevel gears 46 rotate, which in turn drives the crushing rollers 45 to rotate, thus performing preliminary crushing of the scrap iron through the crushing rollers 45.

[0023] like Figure 3 As shown, in some embodiments, the driving bevel gear 44 meshes with the driven bevel gear 46; this facilitates pre-crushing.

[0024] like Figure 2As shown, in some embodiments, the adjustment component 6 includes a support plate 66 fixedly installed on the upper part of the material rack 1. A servo motor 67 is fixedly installed on the support plate 66. Two slide rods 61 are fixedly installed inside each of the two slide grooves 5. A slide plate 62 is slidably connected between the two slide rods 61 on the same side. Both slide plates 62 are fixedly connected to the feed box 3. Threaded rods 63 are rotatably connected inside each of the two slide grooves 5. Rotating gears 64 are fixedly installed on the upper part of each of the two threaded rods 63. The threaded rods 63 are threadedly connected to the slide plate 62. A toothed belt 65 is meshed between the two rotating gears 64. The output shaft of the servo motor 67 is fixedly connected to one of the rotating gears 64. The servo motor 67 drives the rotating gear 64 to rotate, which drives the toothed belt 65 to rotate, which in turn drives the two threaded rods 63 to rotate, causing the slide plate 62 to slide on the slide rods 61, thereby adjusting the height of the feed box 3 to facilitate the adjustment of the feeding height.

[0025] like Figure 1 As shown, in some embodiments, the roller 2 is a universal brake wheel; it facilitates movement while also facilitating positioning.
