Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 This utility model provides the following technical solution: A melting furnace for precious metal processing, comprising: a furnace body 1, mounting plates 2 on both sides of the furnace body 1, an electric telescopic cylinder 3 mounted on the top of the mounting plates 2, an adjusting rod 4 on the top of the electric telescopic cylinder 3, a first bolt 5 threadedly connected to the top of the adjusting rod 4, an adjusting column 6 threadedly connected to the bottom of the first bolt 5, a first rotating shaft 7 rotatably connected to one side of the adjusting column 6, a clamping ring 8 rotatably connected to the other side of the first rotating shaft 7, a melting chamber 9 sleeved on the inner wall of the clamping ring 8, a first clamping plate 10 sleeved on the lower surface of the melting chamber 9, a second rotating shaft 11 rotatably connected to one side of the first clamping plate 10 longitudinally, a second clamping plate 12 rotatably connected to the surface of the second rotating shaft 11, and the second clamping plate 12 abutting against the first clamping plate 1 at its transverse end. At the horizontal end, a second bolt 13 is horizontally connected through the intersection of the first clamping plate 10 and the second clamping plate 12. The surface of the protrusion at the front end of the second clamping plate 12 is rotatably connected to the third rotating shaft 14. The surface of the third rotating shaft 14 is rotatably connected to the upper end of the telescopic rod 15. The bottom surface of the telescopic rod 15 is connected to the top of the horizontal end of the connecting frame 16. The surface of the bottom vertical plate of the connecting frame 16 is rotatably connected to the fourth rotating shaft 17. The surface of the fourth rotating shaft 17 is rotatably connected to the moving block 18. In this design, the smelting furnace body 1 and the smelting chamber 9 constitute the main body of the precious metal smelting furnace. A large number of related components are set in the main body of the precious metal smelting furnace. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0023] In use: Precious metal melting furnaces primarily use electromagnetic induction heating or combustion heating to rapidly heat precious metal raw materials to a molten state. Electromagnetic induction heating utilizes a changing electric current to generate a magnetic field, which in turn induces eddy currents within the precious metal, causing it to heat up and melt. This method offers rapid heating and precise temperature control, making it suitable for processing temperature-sensitive precious metals.

[0024] Preferably, a circular through groove is opened laterally on the side wall of the adjusting rod 4, and the shape and size of the through groove are adapted to the adjusting column 6. The adjusting rod 4, the first bolt 5 and the adjusting column 6 form a threaded connection structure.

[0025] In practical use, the first bolt 5 is used to longitudinally pass through the adjusting rod 4 and then be fixed in the threaded groove at the corresponding position on the top of the adjusting column 6, so as to facilitate fixing the position of the adjusting column 6 on the adjusting rod 4.

[0026] Preferably, the adjusting column 6, the first rotating shaft 7, and the clamping ring 8 form a rotary connection structure.

[0027] In practical use, after the two clamping rings 8 are clamped on the upper end of the melting chamber 9, the clamping rings 8 can be rotated to adjust the angle on one side of the adjusting column 6 by using the first rotating shaft 7 connected between the adjusting column 6 and the clamping rings 8.

[0028] Preferably, two clamping rings 8 are respectively sleeved on the upper surface of the melting chamber 9, and the clamping rings 8 have three sets of limiting teeth distributed in a ring.

[0029] In practical use, the limiting teeth provided on the upper end of the clamping ring 8 are used to stably clamp the melting chamber 9, thereby preventing the melting chamber 9 from sliding when tilting forward.

[0030] Preferably, the first clamping plate 10, the second rotating shaft 11, the second clamping plate 12, and the second bolt 13 form a rotary threaded connection structure.

[0031] In practical use, the lower end of the melting chamber 9 is clamped by the first clamping plate 10 and the second clamping plate 12, and the connection between the first clamping plate 10 and the second clamping plate 12 is fixed by the second bolt 13.

[0032] Preferably, the top of the smelting furnace body 1 has a smelting groove and two circular sluices are respectively opened on both sides, and the shape and size of the sluices are adapted to the moving block 18. The connecting frame 16, the fourth rotating shaft 17 and the moving block 18 form a rotating connection structure.

[0033] In practical use, the sliding groove provided on the top of the smelting furnace body 1 facilitates the sliding movement of the moving block 18 on the top of the smelting furnace body 1 to adjust its position.

[0034] Working principle: During precious metal processing, the precious metal raw materials are melted using the melting chamber 9 fitted onto the top of the melting furnace body 1. After melting, the clamping rings 8 fitted onto the side wall of the adjusting rod 4 move towards the melting chamber 9, thereby clamping the two sides of the melting chamber 9. The first bolt 5 is then longitudinally inserted through the adjusting rod 4 and fixed to the adjusting column 6, facilitating the clamping and lifting of the melting chamber 9. After the melting chamber 9 is clamped and fixed, the electric telescopic cylinders 3 on both sides are activated to lift the melting chamber 9 upwards. Simultaneously, the moving block 18, which is slidably connected to the top of the melting furnace body 1, moves towards the melting chamber 9, thereby clamping the lower end of the melting chamber 9 using the first clamping plate 10 and the second clamping plate 12. The connection between the first clamping plate 10 and the second clamping plate 12 is fixed by the second bolt 13. At this time, the moving block 18 can be moved backward so that it drives the connecting frame 16 to move backward together through the fourth rotating shaft 17 connected above. When moving, the fourth rotating shaft 17 connected between the connecting frame 16 and the moving block 18 adjusts the angle. At the same time, the telescopic rod 15 connected to the top of the connecting frame 16 slides upward, and the third rotating shaft 14 connected to the top of the telescopic rod 15 rotates at the front end of the second bolt 13, thereby driving the melting chamber 9 clamped by the first clamping plate 10 and the second clamping plate 12 to move backward. This causes the clamping ring 8 clamped at the upper end of the melting chamber 9 to tilt forward under the action of the adjusting columns 6 on both sides, pouring out the precious metal liquid in the melting chamber 9.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
