[0024] 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.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a medium frequency melting furnace, including a bracket 1, a material unloading component 5 is installed on the right side of the bracket 1, and the material unloading component 5 is used for unloading the melting furnace. A furnace body 7 is installed on the outside of the material unloading component 5, and the furnace body 7 is rotatably connected to the middle part of the bracket 1. A feeding port 8 is opened on the upper part of the furnace body 7, and fixed blocks 9 are fixedly connected to both sides of the upper part of the furnace body 7. Baffles 10 are arranged inside the two fixed blocks 9, and a mounting block 11 is fixedly connected to the rear side of the upper part of the furnace body 7. A rotating plate 12 is rotatably connected inside the mounting block 11, and the rotating plate 12 is lower A handle 13 is fixedly connected to the rotating plate 12, a connecting frame 14 is rotatably connected to the outside of the rotating plate 12, the connecting frame 14 is sleeved on the outside of the mounting block 11, a baffle 10 is rotatably connected to the right side of the connecting frame 14, sliding grooves 15 are provided inside the two fixed blocks 9, the baffle 10 is slidably connected to the inside of the two sliding grooves 15, extension plates 3 are fixedly connected to the outside of the bracket 1 on both sides, mounting holes are provided inside the two extension plates 3, a placement rack 2 is fixedly connected to the front side of the outside of the bracket 1, a liquid storage barrel is provided on the upper part of the placement rack 2, and the baffle 10 is made of aluminum oxide.

[0026] When using the medium frequency melting furnace, first, pour the metal material to be melted into the furnace body 7 through the feed port 8. This process requires careful operation to ensure that the metal material enters the furnace body 7 accurately to avoid material spillage or loss. After the feeding is completed, the feed port 8 needs to be quickly covered to prevent heat leakage and other operational risks. Next, by lifting the handle 13 upward, the movement of the handle 13 drives the external fixed rotating plate 12 to rotate in a circle inside the mounting block 11. When the rotating plate 12 rotates, it drives the external rotating connection connecting frame 14 to move, so that the connecting frame 14 moves out from the outside of the mounting block 11. In this process, the movement of the connecting frame 14 will synchronously drive the baffle 10 connected to its right side to move inside the two fixed blocks 9. When the baffle 10 moves inside the two fixed blocks 9, it will gradually cover the feed port 8 completely. At this time, the handle 13 can be loosened, and the baffle 10 will stabilize in the position of covering the feed port 8 to ensure that the feed port 8 is covered. After the metal material to be smelted is placed in the furnace body 7, the feed port 8 can be quickly and effectively covered to prevent the molten metal from splashing out, thereby protecting the operator and equipment. The baffle 10 is made of alumina, which has high high temperature resistance and can withstand the high temperature environment in the medium frequency smelting furnace, thereby ensuring that the baffle 10 will not melt or deform during the smelting process.

[0027] Reference Figure 1 and Figure 4 The unloading component 5 includes an electric push rod 501, which is arranged on the right side of the outside of the bracket 1. The output end of the electric push rod 501 is fixedly connected to a rack plate 502, and the lower part of the rack plate 502 is fixedly connected to a guide ring 503. The right side of the inside of the bracket 1 is rotatably connected to a transmission column 505, and the outside of the transmission column 505 is fixedly connected to a gear 504. The gear 504 is meshed with the rack plate 502, and the outside of the transmission column 505 is fixedly connected to a furnace body 7. The right side of the outside of the bracket 1 is fixedly connected to a guide rod 6, and the guide ring 503 is slidably connected to the outside of the guide rod 6. The right side of the upper part of the bracket 1 is fixedly connected to a mounting ring 4, and the electric push rod 501 is fixedly connected to the inside of the mounting ring 4.

[0028] When unloading, first, the baffle 10 is moved away from the feed port 8 by moving the handle 13. This operation makes the feed port 8 completely open and ready for the unloading process. Next, the electric push rod 501 is started. When it is started, the rack plate 502 fixed at the output end of the push rod begins to move. The movement of the rack plate 502 is a linear motion, and the movement of the rack plate 502 drives the upper meshing gear 504 to rotate. During the rotation process of the gear 504, the internal fixed transmission column 505 is driven to rotate inside the bracket 1. The rotation of the transmission column 505 is a key step, which directly drives the tilting movement of the furnace body 7. When the transmission column 505 rotates, it drives the external fixed furnace body 7 to rotate synchronously. At this time, the furnace body 7 gradually tilts to a predetermined angle, so that the molten metal liquid inside the furnace body 7 flows out through the feed port 8. The tilt angle can be adjusted as needed to ensure that the metal liquid can flow out smoothly without overflowing or wasting. The metal liquid flows into the liquid storage barrel placed on the upper part of the placement rack 2 through the feed port 8. The liquid storage barrel is designed to be high temperature resistant and corrosion resistant, and can safely receive and store high temperature metal liquid. After the metal material is smelted, the molten liquid inside the furnace body 7 can be automatically poured out, reducing the dependence on manual labor and reducing labor costs. The installation ring 4 is provided to facilitate the fixing of the electric push rod 501.

[0029] Working principle: When using the medium frequency melting furnace, first, pour the metal material to be melted into the furnace body 7 through the feed port 8, then lift the handle 13 upwards, the handle 13 moves with the external fixed rotating plate 12 to rotate in a circle inside the mounting block 11, and when the rotating plate 12 rotates, it moves with the connecting frame 14 connected to the external rotation, so that the connecting frame 14 is moved out from the outside of the mounting block 11, and then when the connecting frame 14 moves, it moves with the baffle 10 connected to the external right side rotation inside the two fixed blocks 9, so that the baffle 10 blocks the feed port 8, and then the handle 13 can be released to complete the covering of the feed port 8, so that when the metal material to be melted is placed in the furnace body 7, it is convenient to cover the feed port 8, and covering the feed port 8 can prevent the high-temperature molten metal from splashing, reducing the operation The risk of personnel being injured by heat radiation and splashing objects is reduced, and the operational safety is improved. Then, when unloading, the baffle 10 is moved away from the feed port 8 by moving the handle 13, and then the electric push rod 501 is started. The electric push rod 501 moves with the rack plate 502 fixed at the output end, and the rack plate 502 moves with the upper meshing gear 504 to rotate. The gear 504 rotates and drives the internal fixed transmission column 505 to rotate inside the bracket 1. When the transmission column 505 rotates, it drives the external fixed furnace body 7 to rotate, so that the furnace body 7 is tilted at a certain angle, and then the metal liquid inside the furnace body 7 flows into the liquid storage barrel placed on the upper part of the placement rack 2 through the feed port 8. After the metal material is smelted, the molten liquid inside the furnace body 7 can be automatically poured out, which reduces the dependence on manual labor and reduces labor costs.
