Technical Field

[0001] This utility model relates to the field of medium frequency furnace technology, specifically to a medium frequency furnace for alloy melting. Background Technology

[0002] An intermediate frequency furnace is a device that rectifies three-phase industrial frequency alternating current into direct current, and then converts the direct current into an adjustable intermediate frequency current. This intermediate frequency alternating current is supplied to the capacitor and induction coil, generating high-density magnetic lines of force in the induction coil. These lines of force cut through the metal material placed inside the induction coil, generating large eddy currents in the metal material, which then melt the metal.

[0003] Existing medium-frequency furnaces, such as the utility model patent document with authorization announcement number "CN221555067U" and patent name "a medium-frequency furnace tilting device", disclose a medium-frequency furnace including a medium-frequency furnace support. The inner wall of the medium-frequency furnace support is provided with a tilting locking device. A brake wheel is adjacent to the inner side of the medium-frequency furnace support. The rear end face of the brake wheel is fixedly connected to the medium-frequency furnace body. The inner side of the medium-frequency furnace support is rotatably connected to the medium-frequency furnace body. A feeding port is fixedly connected to one side of the medium-frequency furnace body. A servo motor is fixedly connected to the front end face of the medium-frequency furnace body.

[0004] The medium-frequency furnace described in the aforementioned patent document requires operators to manually add the metal scraps to the furnace. When the metal scraps are placed into the furnace, the unmelted metal scraps may generate large sparks upon contact with the molten liquid inside the furnace. These sparks may splash onto the operators, causing injury. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an alloy melting intermediate frequency furnace. This furnace solves the technical problem mentioned in the background art: the metal scraps to be melted in existing intermediate frequency furnaces need to be manually added to the furnace by the operator. When the metal scraps are put into the furnace, the unmelted metal scraps may come into contact with the molten liquid in the furnace, which may generate large sparks. These sparks may splash onto the operator and cause injury.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An alloy melting medium-frequency furnace includes a workbench, a support frame, and a furnace body. The support frame is located on one side of the workbench, and the furnace body is located on one side of the support frame. A conveying pipe for conveying materials toward the furnace body is slidably mounted on the support frame. A mounting cover is fixedly mounted on the workbench. A conveyor for conveying materials toward the feed inlet of the conveying pipe is mounted on the workbench, and the conveyor is located inside the mounting cover. A feed pipe is provided through the mounting cover, and the feed pipe is vertically opposite to the conveyor. A crushing component for crushing materials is provided on the feed pipe. Several drying pipes for drying the materials on the conveyor are provided on the mounting cover.

[0008] Working principle:

[0009] First, the operator puts the metal scraps to be melted into the feed pipe. The crushing component crushes the metal scraps in the feed pipe.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] like Figure 1 and Figure 2 As shown, an alloy melting intermediate frequency furnace includes a workbench 1, a support frame 2, and an intermediate frequency furnace body 3. A mounting cover 5 is fixedly installed on the workbench 1. A conveyor 6 for conveying material towards the feed inlet of a conveying pipe 4 is located on the workbench 1, and the conveyor 6 is situated inside the mounting cover 5. A feed pipe 7 is connected to the mounting cover 5, and the feed pipe 7 is vertically opposite to the conveyor 6. A crushing assembly for crushing material is installed on the feed pipe 7. The crushing assembly includes two crushing rollers 8, two gears 9, and a first motor 10. The two crushing rollers 8 are rotatably disposed within the feed pipe 7 and are used to crush the material passing through the feed pipe 7. Both ends slide through the feed pipe 7 and extend outward. Two gears 9 are fixed to the ends of the two crushing rollers 8 and are located outside the feed pipe 7. The two gears 9 mesh with each other. The first motor 10 is fixed on the mounting cover 5 and the output end of the first motor 10 is fixed to one of the crushing rollers 8. The first motor 10 drives one of the crushing rollers 8, which drives the two gears 9 to rotate. Thus, the two crushing rollers 8 can crush the metal scraps passing through the feed pipe 7. After crushing, the metal scraps can fall onto the conveyor 6. The metal scraps on the conveyor 6 can move toward the conveyor pipe 4 and fall into the conveyor pipe 4.

[0021] like Figure 1 and Figure 3 As shown, the mounting cover 5 is equipped with several drying pipes 12 for drying the materials on the conveyor 6. Several blowers 11 are fixed on the workbench 1. The drying pipes 12 are fixed inside the mounting cover 5 and their outlets face the conveyor 6. Each blower 11 has a connecting pipe 13 at its outlet, and the connecting pipe 13 is connected to the inlet of the drying pipe 12. The blowers 11 can generate hot airflow, which flows through the connecting pipe 13 into the drying pipes 12. The drying pipes 12 can dry the metal scraps passing on the conveyor 6, reducing the residual moisture on the metal scraps.

[0022] like Figure 1As shown, a guide hopper 14 is provided on one side of the mounting cover 5 to guide the material on the conveyor 6 to the feed inlet of the conveying pipe 4. The guide hopper 14 can transport the metal scraps on the conveyor 6 into the conveying pipe 4. The support frame 2 is located on one side of the workbench 1, and the medium frequency furnace body 3 is located on one side of the support frame 2. The support frame 2 is slidably provided with a conveying pipe 4 for conveying material toward the medium frequency furnace body 3. Two guide rails 15 are fixed on the support frame 2. The two guide rails 15 are respectively provided with a screw 16 and a guide rod 17, and the screw 16 and the guide rod 17 are parallel to each other. A second motor 18 is fixed on the support frame 2, and the output end of the second motor 18 is fixedly connected to the screw 16. Slider 19 is slidably provided on both guide rails 15. One slider 19 is screwed to the screw 16, and the other slider 19 is slidably connected to the guide rod 17. Both sliders 19 are fixedly connected to the outer wall of the conveying pipe 4. The second motor 18 drives the screw 16 to drive the slider 19 to slide on the guide rail 15, thereby the slider 19 drives the conveying pipe 4 to move.

[0023] like Figure 1 and Figure 4 As shown, a connecting block 20 is fixed on one of the sliders 19, and a sliding block 21 is fixed on the connecting block 20 and the sliding block 21 is slidably connected to the guide rod 17. A shield 22 for shielding the furnace opening of the medium frequency furnace body 3 is fixed on the sliding block 21. The shield 22 on the connecting block 20 can be moved to the top of the medium frequency furnace body 3 by moving the slider 19.

[0024] Working principle:

[0025] First, the operator places the metal scraps to be melted into the feed pipe 7. The first motor 10 is then started, driving one of the crushing rollers 8 to rotate. This rotation drives two gears 9, allowing the two crushing rollers 8 to crush the metal scraps entering the feed pipe 7, breaking large pieces into smaller metal scraps. The crushed metal scraps then fall onto the conveyor 6, which moves them towards the guide hopper 14. While the conveyor 6 is transporting the metal scraps, the blower 11 is started, generating a hot airflow. This hot airflow can be conducted through the connecting pipe 13 to the drying chamber. Inside the dry pipe 12, the hot airflow inside the drying pipe 12 can dry the metal scrap on the conveyor 6, reducing the residual moisture on the surface of the metal scrap. The dried metal scrap falls onto the guide hopper 14, which can transport the metal scrap to the conveying pipe 4. The conveying pipe 4 can transport the metal scrap to the medium frequency furnace body 3 for melting. After the metal scrap is added, the operator starts the second motor 18, which drives the screw 16. The screw 16 drives the slider 19 to move within the guide rail 15, thereby the slider 19 drives the shield 22 on the connecting block 20 to move to the furnace mouth of the medium frequency furnace body 3.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
