Description
Technical Field
[0001] This utility model relates to the field of melting furnaces, and in particular to a vacuum induction melting furnace with the prevention of residual metal. Background Technology
[0002] The working principle of vacuum induction melting: Eddy currents are generated during electromagnetic induction, which melt the metal. This process can be used to refine high-purity metals and alloys. Vacuum induction melting mainly includes vacuum induction furnace melting, suspension melting and cold crucible melting. Because melting under vacuum makes it easier to remove nitrogen, hydrogen, oxygen and carbon dissolved in steel and alloys to a level much lower than that of smelting under normal pressure.
[0003] However, existing vacuum induction melting furnaces often add other metals during the melting process, and the stirring mechanism in most vacuum induction melting furnaces is a single-axis stirring mechanism, which leads to uneven stirring, affecting the quality of metal melting. In addition, the metal will remain on the inner wall of the melting furnace after melting, which is not convenient for subsequent processing. Utility Model Content
[0004] In order to overcome the fact that most of the stirring mechanisms in existing vacuum induction melting furnaces are single-axis stirring, which leads to uneven stirring, affecting the quality of metal melting, and leaving metal residue on the inner wall of the melting furnace after melting, which is inconvenient for subsequent processing.

Electronic valves are provided on the inner sides of both the feed inlet and the discharge outlet, allowing materials to be input and output through the feed inlet and the discharge outlet.
[0008] Preferably, a control panel is fixedly connected to the front end of the melting shell.

[0010] Preferably, stirring rod A and transmission gear C are integrated into one structure, and stirring rod B and transmission gear D are integrated into one structure.

[0011] Preferably, the bottom of the device top cover is provided with a rotating groove, and when the transmission gear D drives the stirring rod B to rotate, the stirring rod B rotates inside the rotating groove.
[0012] Preferably, a cleaning wall mount is provided on the outer side of the stirring rod B, with one end of the cleaning wall mount fitting against the inner wall of the smelting shell. When the stirring rod B rotates, the cleaning wall mount contacts the inner wall of the smelting shell.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment of a vacuum induction melting furnace for preventing residual metal, comprising a melting shell 1, a device top cover 3 fixedly connected to the top of the melting shell 1, a rotating seat 4 rotatably connected to the top of the device top cover 3, a transmission gear A6 provided on the outer side of the rotating seat 4, a rotating assembly provided at one end of the transmission gear A6, the rotating assembly being used to connect the rotating seat 4 and the device top cover 3, a stirring rod A9 rotatably connected to the center position of the bottom end of the rotating seat 4, stirring rods B10 provided on both sides of the stirring rod A9, a transmission assembly provided at the top of the stirring rod B10, the transmission assembly being used to connect the stirring rod A9 and the stirring rod B10; the rotating assembly includes a servo motor B7, the output end of the servo motor B7 is fixedly connected to a transmission gear B8, the servo motor... B7 is the drive mechanism for transmission gear B8. Transmission gear B8 meshes with servo motor A5. When servo motor B7 drives transmission gear B8 to rotate, transmission gear B8 transmits the power of servo motor B7 to transmission gear A6, thereby causing the rotating seat 4 to rotate inside the top cover 3 of the device. The transmission assembly includes servo motor A5. The output end of servo motor A5 is fixedly connected to transmission gear C12. Servo motor A5 is the drive mechanism for transmission gear C12. Transmission gears D13 are provided on both sides of transmission gear C12. Transmission gear C12 meshes with the two transmission gears D13. When servo motor A5 drives transmission gear C12 to rotate, transmission gear C12 transmits the power of servo motor A5 to transmission gear D13.
[0024] Please see Figures 2-3 In this embodiment, a feed inlet is provided on the top surface of the rear end of the smelting shell 1, and a discharge outlet is provided at the bottom end of the smelting shell 1. Electronic valves are provided on the inner sides of both the feed inlet and the discharge outlet, allowing materials to be input and output through the feed inlet and the discharge outlet. A control panel 2 is fixedly connected to the front end of the smelting shell 1. The control panel 2 is electrically connected to the rotating assembly, the transmission assembly, and the electronic valves, allowing the control panel 2 to control the rotating assembly, the transmission assembly, and the electronic valves separately. A rotating hole is provided at the top of the device top cover 3, and a rotating seat 4 extends to the inner side of the smelting shell 1 through the rotating hole. Sealing gaskets are provided at the intersection of the rotating seat 4 and the rotating hole. When the rotating seat 4 rotates through the rotating assembly, the rotating seat 4 rotates inside the rotating hole.
[0025] Please see Figures 4-5In this embodiment, the stirring rod A9 and the transmission gear C12 are integrated, and the stirring rod B10 and the transmission gear D13 are integrated. When the servo motor A5 drives the transmission gear C12 to rotate, the transmission gear C12, in conjunction with the transmission gear D13, drives the stirring rod A9 and the stirring rod B10 to rotate respectively. A rotating groove is provided at the bottom of the device top cover 3. When the transmission gear D13 drives the stirring rod B10 to rotate, the stirring rod B10 rotates inside the rotating groove. A cleaning wall hanger 11 is provided on the outside of the stirring rod B10. One end of the cleaning wall hanger 11 is attached to the inner wall of the smelting shell 1. When the stirring rod B10 rotates, the cleaning wall hanger 11 contacts the inner wall of the smelting shell 1.
[0026] During operation, metal is injected into the melting shell 1, the power is turned on, and the device is started. The melting shell 1 achieves metal melting and refining through the synergistic effect of electromagnetic induction heating and vacuum environment. While refining the metal, the transmission gear C12 is driven to rotate by the servo motor A5. The transmission gear C12, in conjunction with the transmission gear D13, drives the stirring rods A9 and B10 to rotate respectively. Thus, the stirring rods A9 and B10 achieve multi-axis stirring, improving the stirring quality of the device. At the same time as the stirring rods A9 and B10 are stirring, the transmission gear B8 is driven to rotate by the servo motor B7. The transmission gear B8, in conjunction with the transmission gear A6, causes the rotating seat 4 to rotate inside the top cover 3 of the device. A cleaning wall hanger 11 is provided on the outside of the stirring rod B10, so that the cleaning wall hanger 11 cleans the inner wall of the melting shell 1 during the rotation of the stirring rod B10, preventing metal residue from accumulating on the inner wall of the melting shell 1 and affecting subsequent metal melting.
[0027] Through the above steps, multi-axis stirring is achieved by using stirring rod A9 in conjunction with stirring rod B10, thereby improving the stirring quality of the device. Furthermore, a cleaning wall mount 11 is provided on the outer side of stirring rod B10, which cleans the inner wall of the melting shell 1 during the rotation of stirring rod B10. This addresses the problem that most stirring mechanisms in existing vacuum induction melting furnaces are single-axis stirring, which can lead to uneven stirring, affecting the quality of metal melting. Additionally, metal residues left on the inner wall of the melting furnace after melting are difficult to process later.
