Description

Technical Field

[0001] This utility model relates to the field of casting electric furnace technology, specifically a feeding device for casting electric furnaces. Background Technology

[0002] Electric casting furnaces are core equipment in the modern casting industry for metal smelting. They convert electrical energy into heat energy to melt, refine, and alloy metal materials, and are widely used in the casting production of steel, non-ferrous metals, and special alloys.

[0003] During production, casting electric furnaces require feeding equipment to feed raw materials into the furnace. In existing technology, a hopper is typically used in conjunction with an auger to feed the furnace. However, because the material volume is usually small and it is easy to slide inside the device, some material will slide out when the auger stops feeding. This results in the auger being unable to feed the furnace quantitatively. Furthermore, when the auger is feeding, the material is prone to clogging, which can block the hopper and reduce the overall feeding speed of the device. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for casting electric furnaces, which solves the technical problems that the aforementioned auger cannot quantitatively feed materials to the casting electric furnace, and that the materials are prone to clogging together during feeding, thereby blocking the hopper and reducing the overall feeding speed of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A feeding device for a casting electric furnace includes: a feeding box 1 and a storage box 2. The storage box 2 and the feeding box 1 are connected by an inclined tube 21. A motor 4 is mounted on the right side of the feeding box 1 via a frame 41. A feeding roller 5 is mounted on the output shaft of the motor 4. A stirring mechanism 3 is mounted on the left side of the feeding roller 5.

[0024] The feeding box 1 and the storage box 2 can store materials, and the motor 4 can drive the feeding roller 5, which can quantitatively discharge materials into the interior of the casting furnace.

[0025] Please see Figure 3 and Figure 4 The stirring mechanism 3 includes a horizontal shaft 31, which is connected to the feeding roller 5. A first conical tooth 32 is fixedly connected to the outside of the horizontal shaft 31. A second conical tooth 33 is meshed with the outside of the first conical tooth 32. A stirring rod 34 is mounted on the top of the second conical tooth 33.

[0026] The horizontal shaft 31 can drive the first conical tooth 32 to rotate, which in turn drives the second conical tooth 33 to rotate, while the stirring rod 34 can agitate the material inside the storage box 2.

[0027] The bottom of the feeding box 1 is connected to the feeding port 11. The bottom of the inner cavity of the feeding box 1 is equipped with a guide plate 12. The feeding box 1 and the storage box 2 are connected by a bent arm 23. The guide plate 12 can guide the material inside the feeding box 1, so that the material can smoothly enter the inner cavity of the feeding port 11 for discharge. The upper and lower ends of the feeding roller 5 are provided with square grooves. The inner cavity of the square groove is embedded with a protective pad. The square groove can allow the material to enter the inner cavity of the feeding roller 5 and be discharged as the feeding roller 5 rotates.

[0028] Both the horizontal shaft 31 and the stirring rod 34 are fitted with sealed bearings 36. The two sets of sealed bearings 36 are connected to the feed box 1 and the storage box 2 respectively. The sealed bearings 36 can improve the stability of the horizontal shaft 31 and the stirring rod 34 during transmission. The top of the stirring rod 34 is equipped with a spherical bearing 35. The outside of the spherical bearing 35 is connected to the inner cavity of the storage box 2 through the cross arm. The spherical bearing 35 can support the stirring rod 34 and improve the stability of the stirring rod 34 during movement. The top of the storage box 2 is connected to the hopper 22. The bottom of the inner cavity of the hopper 22 is designed with a slope. The sloped design of the hopper 22 makes it easy for all materials to enter the interior of the storage box 2. The hopper 22 can store materials.

[0029] This scheme connects the feed inlet 11 to the inside of the feed inlet of the casting electric furnace, pours the material into the inner cavity of the hopper 22, and the material enters the inner cavity of the feed box 1 through the hopper 22, the storage box 2 and the inclined tube 21. The motor 4 is started to drive the feeding roller 5 to rotate, which in turn drives the material into the inside of the square groove. The material is discharged into the inside of the casting electric furnace by the rotation of the feeding roller 5. At the same time, the rotation of the feeding roller 5 drives the horizontal shaft 31 to drive the first conical tooth 32 to rotate, which in turn drives the meshing second conical tooth 33 and the stirring rod 34 to rotate, so as to avoid the material inside the storage box 2 from being blocked together.

[0030] By adding a motor 4 and a feeding roller 5, the material is driven to feed in a quantitative manner, avoiding the problem that in traditional devices, when feeding the casting furnace, the material is easily affected by its weight and rolls into the casting furnace, thus making it impossible to feed in a quantitative manner. At the same time, by adding a horizontal shaft 31, a first conical tooth 32, a second conical tooth 33 and a stirring rod 34, the material inside the storage box 2 is automatically driven to stir when the feeding box 1 is feeding, so as to avoid the material inside the storage box 2 from accumulating and blocking the storage box 2.
