Description

Technical Field

[0001] The present invention relates to the technical field of metal waste treatment, and particularly to a DC plasma furnace melting device for metal waste. Background Art

[0002] Metal waste is a waste generated during the metal smelting process, mainly divided into non-ferrous metal slag and steel smelting slag. The DC plasma furnace melting device is a device that uses plasma technology for metal melting. The DC plasma furnace has the characteristics of high efficiency, energy saving and environmental friendliness, and is widely used in metal recycling, smelting and the production of special alloys.

[0003] At present, most DC plasma furnace melting devices generate a strong plasma arc by inserting a pole column into the furnace body to melt metal waste. However, during the melting process, the electrode will generate a high-temperature plasma arc, and the slag becomes highly fluid at high temperatures and may be attracted and adhered to the surface of the electrode. When the accumulated amount is too large, it is likely to affect the conductivity of the electrode and the melting efficiency. In addition, harmful gases are generated during the melting of the waste, which is likely to affect the human body. However, most of the current DC plasma furnaces have an open feed inlet, so some of the harmful gases generated during melting are easily discharged through the feed inlet, which is likely to affect the processing environment. In view of the above problems, the inventor proposes a DC plasma furnace melting device for metal waste to solve the above problems. Summary of the Invention

[0050] By adopting the above technical solution, the installation rod 406 can drive the rotating plate 402 and the sealing plate 403 to rotate.

[0051] Working principle: First, turn on the fourth motor 408 to drive the mounting rod 406 to rotate. The rotation of the mounting rod 406 drives the fourth bevel gear 407 to rotate. The rotation of the fourth bevel gear 407 drives the third bevel gear 404 to rotate. The rotation of the two third bevel gears 404 drives the rotating plate 402 and the sealing plate 403 to rotate respectively. At this time, the rotation of the rotating plate 402 opens the feed inlet, and the rotation of the sealing plate 403 closes the exhaust port. Then, turn on the second electric cylinder 411 to drive the moving plate 409 to move. The movement of the moving plate 409 opens the discharge port. At this time, the metal waste residue is transported into the lower material box 401 through the feeding equipment and enters the processing box 101 through the lower material box 401. After the feeding is completed, turn on the fourth motor 408 to drive the rotating plate 402 and the sealing plate 403 to rotate, close the feed inlet and open the exhaust port;

[0052] Secondly, turn on the third motor 316 to drive the multi-stage bidirectional screw 315 to rotate. The rotation of the multi-stage bidirectional screw 315 drives the slide bar 314 to move. The movement of the slide bar 314 drives the moving frame 313 to move, so that the mutually approaching sides of the moving frames 313 are in contact with each other. At this time, the movement of the slide bar 314 drives the limiting bar 318 to move. The movement of the limiting bar 318 drives the sealing seat 317 to move, so that the mutually approaching sides of the sealing seats 317 are in contact with each other;

[0053] Then, turn on the first electric cylinder 311 to drive the mounting plate 326 to move. The movement of the mounting plate 326 drives the rack 327 to move. When the rack 327 meshes with the external gear ring 325, it drives the external gear ring 325 to rotate. The rotation of the external gear ring 325 drives the internal gear ring 324 to rotate. The rotation of the internal gear ring 324 drives the second gear 323 to rotate. The rotation of the second gear 323 drives the vertical rod 321 to rotate. The rotation of the vertical rod 321 drives the second bevel gear 322 to rotate. The rotation of the second bevel gear 322 drives the first bevel gear 320 to rotate. The rotation of the first bevel gear 320 drives the drive screw 319 to rotate. The rotation of the drive screw 319 drives the slider 310 to move. The movement of the slider 310 drives the cleaning pipe 307 to move, so that the mutually approaching sides of the cleaning pipes 307 are in contact with each other;

[0054] Then, turn on the first motor 209 to drive the rotating rod 206 to rotate. The rotation of the rotating rod 206 drives the winding disc 207 to rotate. The rotation of the winding disc 207 drives the steel rope 208 to move. The movement of the steel rope 208 drives the moving seat 203 to move. The movement of the moving seat 203 drives the pole 205 to move, so that the pole 205 moves downward and inserts into the cleaning pipe 307;

[0055] At this time, the second motor 305 is turned on to drive the first gear 306 to rotate. The rotation of the first gear 306 drives the first toothed ring 304 located on the left to rotate. At this time, since the two first toothed rings 304 are meshed with each other, the other first toothed ring 304 is driven to rotate. The rotation of the first toothed ring 304 drives the rotating pipe 303 to rotate. The rotation of the rotating pipe 303 drives the rotating disk 302 to rotate. The rotation of the rotating disk 302 drives the cleaning pipe 307 to rotate. The trapezoidal scraper on the inner wall of the cleaning pipe 307 cleans the slag on the outer surface of the terminal post 205.

[0056] At this time, the cleaned slag falls on the upper surface of the moving frame 313. At this time, the rotation of the rotating pipe 303 drives the push rod 309 to perform a circular motion. At this time, the circular motion of the push rod 309 drives the slag to move, so that the slag is discharged from the inside of the cleaning box 301 through the inclined plate 308.

[0057] Finally, when feeding materials in the middle of smelting, the second electric cylinder 411 is turned on to drive the moving plate 409 to move. The movement of the moving plate 409 seals the discharge port of the feeding box 401 to prevent the harmful gas generated by smelting from floating out through the discharge port. Then, the fourth motor 408 is turned on to rotate the rotating plate 402 and the sealing plate 403, opening the feeding port and closing the exhaust port. At this time, the raw materials are transported by the feeding equipment so that the raw materials enter the inside of the feeding box 401. At this time, the raw materials are piled up on the moving plate 409. When the feeding reaches a certain amount, the fourth motor 408 is turned on to rotate the rotating plate 402 and the sealing plate 403, closing the feeding port and opening the exhaust port to prevent the harmful gas from smelting from being discharged through the feeding port. Then, the second electric cylinder 411 is turned on to drive the moving plate 409 to move, opening the discharge port of the feeding box 401 so that the added raw materials enter the inside of the processing box 101.

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
