[0031] When in use, place the device in a suitable position, then assemble the mounting frame assembly 1 and the smelting device 2, the base 14 is in close contact with the ground to ensure the stability of the entire furnace body, install the heat-insulating tube 10 inside the outer tube 21, and quickly install the inner tube assembly 3 inside the heat-insulating tube 10 through the locking structure 8. The second telescopic rod 81 is engaged with the card groove 42 on the outer wall of the furnace tube 41 under the action of the return spring 82 to achieve a firm fixation of the inner tube assembly 3. At the same time, the filter structure 11 is placed inside the furnace tube 41 set with the smelting structure 4, and then The copper material to be smelted is placed inside the melting furnace tube 41, and finally the sealing plate 71 provided inside the sealing assembly 7 is clamped to the top of the melting furnace tube 41 to form a closed space inside the melting furnace tube 41. The support frame 15 provides an installation position and support for the servo motor 13. When the servo motor 13 is powered on, it drives the outer tube 21 to swing through the rotating shaft, thereby assisting the melting of the copper material during the melting process. Then, the first resistance belt 51 and the second resistance belt 53 are powered on to generate high temperature, which heats the melting furnace tube 41 and achieves the effect of melting the copper material.

[0032] The dustproof plate 125 provided inside the protective structure 12 can prevent dust from entering. When the heating structure 5 is installed or repaired, an external force pushes the dustproof plate 125 upward, and the bellows 122 extends and deforms accordingly, providing space for the operation of the heating structure 5. After the operation is completed, the dustproof plate 125 is reset under the action of the spring force to continue to protect the heating structure 5.

[0033] When the furnace tube 41 needs to be installed, the slot 42 below the tube wall will squeeze the arc-shaped clamping plate 83 provided inside the locking structure 8.

The first telescopic rod 73 and the first thrust spring 74 cooperate to provide elastic support for the special-shaped fixing block 75, so that the sealing plate 71 fits tightly against the thickened eaves 43 to achieve dynamic sealing, preventing copper liquid from splashing and heat loss, and then the handle 112 can be fixed by the special-shaped fixing block 75 to prevent the filter tube 111 arranged inside the filter structure 11 from shaking during the smelting process.

The dustproof plate 125 of the protective structure 12 is elastically connected to the bellows 122 through the third telescopic rod 123. When idle, it falls and seals the dustproof box 121 to prevent dust accumulation.

[0036] The copper material is placed in the furnace tube 41, and the heating structure 5 is started. The first resistance belt 51 and the second resistance belt 53 work simultaneously to heat and melt the copper material in the furnace tube 41. The heat circulation component 9 plays a role, and the insulation sleeve 91 retains the heat in the furnace. The heat is recycled through the circulation channel composed of the hose 96, the connecting pipe 92, the air supply pipe 93, the installation pipe 94 and the air outlet pipe 95, thereby improving energy utilization and reducing heat loss. At the same time, the air supply pipe 93 will drive the stirring component 6 to operate when supplying air. The rotating rod 61 drives the thickening block 62, the stirring plate 63 and the impeller 64 to stir the molten copper liquid, so that the copper liquid is heated more evenly and the melting process is accelerated.

[0037] When the copper liquid is melted, it passes through the filter cylinder 111 of the filter structure 11, and the impurities therein are intercepted, separating the sealing plate 71 from the furnace cylinder 41. The staff then takes out the filter cylinder 111 by holding the handle 112 with protective gear, and the impurities in the melted copper can be separated from the melted copper. The pure copper liquid enters the subsequent casting link. During the entire smelting process, the dustproof plate 125 of the protective structure 12 is tightly fitted with the dustproof box 121 under the action of the second thrust spring 124 and the third telescopic rod 123, preventing dust, impurities, etc. from entering the heating structure 5, thereby ensuring the stable operation of the heating structure 5.
