[0002] Gold processing is an industry that combines exquisite craftsmanship with advanced technology. First, using specialized melting equipment, such as gold melting furnaces and vacuum melting furnaces, the raw gold is heated to its melting point. This process requires precise control of temperature and environment to prevent oxidation and the introduction of impurities. The molten gold is then cast into bars, ingots, or specific blanks. Subsequently, according to design requirements, it undergoes fine processing using techniques such as forging, stamping, wire drawing, and inlaying to create a variety of beautiful and uniquely shaped gold jewelry pieces, or high-precision gold products that meet industrial needs. These finished products not only possess extremely high aesthetic value and are highly sought after in the jewelry market, but also play a crucial role in high-end industrial fields such as electronics and aerospace due to gold's excellent physical and chemical properties, carrying both economic and practical value.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7 This utility model provides a technical solution:

[0025] like Figures 1-2 As shown, the device includes a base plate 1, a melting chamber 2 at the top of the base plate 1, a holding tank 8 at the bottom of the melting chamber 2 for holding molten gold, and an induction coil 6 on the inner wall of the melting chamber 2 for melting the gold. It also includes:

[0026] Top cover unit 3 is used to ensure the airtightness of melting chamber 2 and to collect vaporized gold;

[0027] The intermediate frequency power supply cabinet 4 has a circuit board 5 fixedly connected to its outer surface for transmitting power to the induction coil 6.

[0028] The condensation unit 7 is used to condense the air containing gaseous gold, thereby recovering the gold.

[0029] In operation, solid gold is first placed in the container 8, and then the intermediate frequency power supply cabinet 4 is turned on, so that current passes through the induction coil 6. The current generates a magnetic field effect to heat the gold, thereby melting the gold. During this process, the top cover unit 3 ensures the sealing of the device and collects the vaporized gold, which is then recovered through the condensation unit 7.

[0030] like Figures 3-4 As shown, the top cover unit 3 includes a cover plate 31. When melting gold, the cover plate 31 is placed on top of the melting chamber 2. A detachable vent plate 32 is provided on the cover plate 31. A servo motor 33 is provided on the top of the cover plate 31. A rotating shaft 34 is fixedly connected to the output end of the servo motor 33. A rotating base plate 35 is fixedly connected to the bottom of the rotating shaft 34. An air extraction device 36 is fixedly connected to the outer surface of the rotating base plate 35. An air inlet 37 is fixedly connected to the top of the air extraction device 36. A descaling mechanism 38 is provided on the side of the air extraction device 36 away from the rotating base plate 35 to filter out dirt in the air and prevent dirt from adhering and affecting the recovery of gold.

[0031] When heating gold, the cover plate 31 needs to be placed on top of the melting chamber 2. Then, the servo motor 33 will drive the rotating shaft 34 to rotate, which in turn drives the descaling mechanism 38 to rotate along the bottom of the cover plate 31. The rotation will drive the top gas into the descaling mechanism 38, and then the suction device 36 will suck the gas into the interior.

[0032] like Figures 5-6 The descaling mechanism 38 includes a processing plate 381. The inner wall of the processing plate 381 is provided with a double-layer partition 382. The outer surface of the double-layer partition 382 is relatively rough and is used to collect dirt in the air. One end of the processing plate 381 is provided with a dirt chamber 383. One end of the dirt chamber 383 of the processing plate 381 is provided with an electromagnetic plate 384. The bottom of the processing plate 381 is provided with a guide rod 385. The outer surface of the guide rod 385 is slidably connected with a moving ring 386. The top of the moving ring 386 is fixedly connected with a magnetic block 387. The outer surface of the moving ring 386 is provided with two scraping plates 388 that are in contact with the double-layer partition 382.

[0033] When the gas enters the processing plate 381, it comes into contact with the double-layer partition 382. The vaporized gold and dust impurities in the air are adhering to the double-layer partition. The rotation of the processing plate 381 generates centrifugal force, which causes the moving ring 386 to move and drives the scraping plate 388 to scrape the dust adhering to the double-layer partition 382 into the stain bin 383, thereby cleaning the double-layer partition 382. The moving ring 386 can be reset by generating magnetic force through the electromagnetic plate 384 to attract the magnetic block 387.

[0034] The outer surface of the processing plate 381 is fixedly connected to the outer surface of the air extraction device 36.

[0035] like Figure 7 As shown, the condensation unit 7 includes a support plate 71, an inlet pipe 72 is placed on the top of the support plate 71, a condensation pipe 73 is fixedly connected to the top of the inlet pipe 72, a water storage tank 74 is provided in the middle of the condensation pipe 73, an inlet 75 is provided on the top of the water storage tank 74, and a collection box 76 is fixedly connected to the end of the condensation pipe 73 away from the inlet pipe 72.

[0036] After the vaporized gold enters the suction device 36, the servo motor 33 will drive the suction device 36 to be located below the vent plate 32. At this time, the vent plate 32 is removed and the inlet pipe 72 is inserted into the air inlet 37. The vaporized gold will enter the condenser pipe 73. After contacting the condensate in the water storage tank 74, it will condense into gold particles and fall into the collection box 76, realizing the recycling of vaporized gold.

[0037] The outer surface of the support plate 71 is fixedly connected to the end of the base plate 1 away from the intermediate frequency power cabinet 4, and the gas inlet 37 is adapted to the inlet pipe 72.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
