Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown, this embodiment provides a medium-frequency electric furnace with an adaptive early warning device, including: electric furnace 1.

[0029] like Figure 1-5As shown, in this embodiment, the electric furnace 1 has an inner furnace 2 inside, and a heating tube 3 is arranged between the electric furnace 1 and the inner furnace 2. The top of the electric furnace 1 is equipped with a furnace cover 4. Support frames 6 are arranged on the left and right sides of the electric furnace 1. Support frame 9 is arranged on the top of support frame 6. A movable plate 10 is arranged below support frame 9. A detection rod 13 is vertically installed through the center of support frame 9. The detection rod 13 passes through the movable plate 10 and is fixed with a clamp 1001 at the bottom of the movable plate 10. Height adjustment screws 11 are vertically installed on both sides of support frame 9. A motor 12 is arranged on the top of the height adjustment screw 11. A controller 17 is arranged on the side of motor 12. The controller 17 and the detection rod 13 are connected through a connecting bus 16. Multiple openings are made on the surface of the detection rod 13. An installation cavity 1301 is provided, and a detection device 14 is installed inside the installation cavity 1301. The inner furnace 2 is placed in the electric furnace 1 and heated by the heating tube 3. The detection rod 13 passes through the support frame 9 and the movable plate 10 from the top and is fixed to the movable plate 10 by the fixing clamp 1001. The height adjustment screws 11 on both sides pass through the threaded holes of the movable plate 10. The motor 12 drives the height adjustment screws 11 to rotate and move the movable plate 10 downward. The furnace cover 4 has a hole. As the movable plate 10 is lowered, the detection rod 13 is inserted into the electric furnace 1. The detection device 14 on the detection rod 13 can detect the current environment of the inner furnace 2. The detection device 14 is controlled and collects data by the controller 17.

[0030] like Figure 1-5 As shown, in this embodiment, the detection rod 13 has multiple sets of vertically opened circuit pipes 1302 inside, and the detection device 14 has a connecting branch line 1401 on its side. The top of the connecting branch line 1401 is connected to the connecting bus 16, and the top of the detection rod 13 is provided with a retaining ring 15. The detection rod 13 has multiple sets of mounting cavities 1301, and each set of mounting cavities 1301 can install a detection device 14. The detection device 14 is arranged in the detection rod 13 through the circuit pipes 1302 via a single connecting branch line 1401. The multiple sets of mounting cavities 1301 and multiple sets of circuit pipes 1302 are vertically distributed at the edge of the mounting cavity 1301. Each set of circuit pipes 1302 does not interfere with each other. Finally, all the connecting branch lines 1401 extend from the top of the detection rod 13, are wrapped and fixed by the retaining ring 15, and are then covered by the connecting bus 16. Finally, they are connected to the controller 17 for unified control, so that multiple detection devices 14 can work simultaneously in one test.

[0031] like Figure 1As shown, the electric furnace 1 in this embodiment has a discharge port 5 on its front side, and a motor 8 is provided on one side of the support frame 6. The center of the motor 8 is provided with a support shaft 7 facing the electric furnace 1. The electric furnace 1 is supported by the support shaft 7 on the support frame 6. The motor 8 drives the support shaft 7 to rotate, causing the entire electric furnace 1 to rotate and tilt towards the discharge port 5, thereby dumping the heated material in the electric furnace 1. During dumping, the detection rod 13 rises to the highest point to prevent jamming.

[0032] like Figure 1 , 3 As shown, in this embodiment, the electric furnace 1 has a base plate 18 at its bottom. A power supply device 26 is located on the top of the base plate 18 at the back of the electric furnace 1. Support frames 3 19 are located on both sides of the power supply device 26. A movable cavity 1901 is opened at the top of the support frame 3 19. A connecting screw 21 and a support plate 20 are installed inside the movable cavity 1901. The support plate 20 and the connecting screw 21 are installed vertically. A motor 3 22 is located on the back of the support frame 3 19. An interface 23 is located at the front end of the support plate 20. A connecting seat 25 is located on the top of the power supply device 26. The connecting seat 25 and the interface 23 are connected by a power supply line 24. The electric furnace 1... A plug plate 101 is provided on the back; wherein, the power supply device 26 is connected to the interface 23 through the power supply line 24 on the connector 25, and the interface 23 is inserted into the plug plate 101, so that the power supply device 26 supplies power to heat the heating tube 3. The support plate 20 is L-shaped, and the interface 23 is installed on the support plate 20, with the front end aligned with the plug plate 101 on the electric furnace 1. The threaded hole on the support plate 20 passes through the docking screw 21. The motor 3 22 controls the rotation of the docking screw 21 to move the support plate 20 in the movable cavity 1901, which drives the interface 23 to approach and insert into the plug plate 101, thereby connecting the power supply device 26 and the heating tube 3.

[0033] like Figure 4 As shown, in this embodiment, there is a distance between the bottom of the electric furnace 1 and the base plate 18; wherein, the electric furnace 1 is supported and rotated by the support shaft 7 on the support frame 6, and the reserved distance is used to prevent the electric furnace 1 from hitting the base plate 18 when rotating.

[0034] like Figure 1-3 As shown, in this embodiment, a sufficiently long distance needs to be reserved between the connecting bus 16 and the power supply line 24; wherein, the detection rod 13 at one end of the connecting bus 16 and the interface 23 at one end of the power supply line 24 can both move, so that the distance between the two ends will change due to adjustment, and a reserved distance is needed to prevent the corresponding wires from being torn off.

[0035] Working principle: The corresponding testing device 14 is pre-installed on the testing rod 13. The connecting branch line 1401 passes through the line pipe 1302 and extends from one end of the testing rod 13. It is fixed by the retaining ring 15 and finally connected to the controller 17. The inner furnace 2 is installed in the electric furnace 1. Materials are added. The motor 3 22 drives the docking screw 21 to rotate and push the interface 23 on the support plate 20 forward to insert into the insertion plate 101 of the electric furnace 1. The heating tube 3 is connected and heated by the power supply device 26. After running for a period of time, the motor 2 12 is started and controlled by the height adjustment screw 11. The movable plate 10 descends, causing the detection rod 13 to pass through the hole on the furnace cover 4 and be inserted into the inner furnace 2 for detection. After the controller 17 collects the detection information, the second motor 12 rotates the height adjustment screw 11 in the opposite direction to lift the movable plate 10 and the detection rod 13. Based on the detection information, it is determined whether to continue heating or shut down the electric furnace 1. When shutting down the electric furnace 1, the third motor 22 rotates the docking screw 21 in the opposite direction to move the support plate 20, thereby disconnecting the interface 23 and the insertion plate 101, stopping the power supply, and finally the first motor 8 controls the support shaft 7 to rotate, and the electric furnace 1 tilts towards the discharge port 5 to discharge the material.
