[0002] High-strength and high-conductivity copper alloys have strong toughness. Copper alloys are often used to manufacture valves, water pipes, air conditioner indoor and outdoor unit connecting pipes and radiators. Copper alloy strips have a large market demand and wide range of applications due to their good mechanical properties. In the processing and production of copper alloy strips, a smelting device is required to smelt the raw materials.

[0003] In existing copper alloy smelting processes, the raw materials are directly guided through a feeding device. However, the particle size of the raw materials is not uniform, and the melting rate of these different-sized particles varies during the smelting process. This results in the presence of solid metal within the molten metal, altering the alloy composition and affecting the quality of the final alloy. Waiting for complete melting takes considerable time, reducing the processing efficiency of copper alloy strips. Therefore, optimization and improvement are necessary in the application of this technology. Utility Model Content

Figure 2 As shown, a packing port 4 is fixedly installed at the top of the smelting furnace 3. The smelting furnace 3 is used to smelt and process copper alloy smelting raw materials. A discharge pipe 5 is fixedly installed at one end of the outer side of the smelting furnace 3. The discharge pipe 5 is used to discharge the smelted raw materials.

[0019] The filler treatment assembly includes a feed box 6, which is fixedly connected to the top of the support frame 2. A discharge frame 8 is fixedly installed on one side of the feed box 6, and a turntable 11 is connected to the bottom of the discharge frame 8. A shredding roller 13 is connected to the inner side of the feed box 6. The filler treatment assembly is used for pretreatment before the preparation of steel alloy strip; specifically, such as... Figure 2 As shown, a discharge square tube 7 is fixedly connected to one end of the feed box 6. The size of the discharge square tube 7 is adapted to the size of the filling port 4. The discharge square tube 7 is square, which facilitates the dispersion and filling of the smelting raw materials and improves the smelting effect.

[0020] Specifically, such as Figure 3 As shown, a screen 9 is fixedly connected to one end of the feeding frame 8. The feeding frame 8 is inclined so that the raw material can slide downward under the action of gravity. A motor 10 is fixedly installed at the bottom of the feeding frame 8.

[0021] Specifically, such as Figure 3 As shown, the turntable 11 is connected to one output end of the motor 10, and an elastic telescopic block 12 is slidably connected to the inner side of the turntable 11. The motor 10 drives the turntable 11 to rotate. Four elastic telescopic blocks 12 are provided and are evenly distributed on the inner side of the turntable 11. The elastic telescopic blocks 12 are guided and elastically connected by guide rods, so that when the turntable 11 rotates, the elastic telescopic blocks 12 are thrown out to hit the bottom of the feeding frame 8.

[0022] Specifically, such as Figure 2 As shown, a shredding roller 13 is rotatably connected to the inner side of the feed box 6, and there are two shredding rollers 13. The screening screen 9 guides the larger particles after screening the raw material to the middle of the two shredding rollers 13 for shredding.

[0023] The sorting and transfer assembly includes a folding cover plate 14 and a collection hopper 20. The folding cover plate 14 is hinged to the top of the feed box 6, and a feed baffle 18 is connected to the inner side of the folding cover plate 14. The collection hopper 20 is connected to one end of the inside of the feed box 6. The sorting and transfer assembly is used for sorting and transferring raw materials.

[0024] Specifically, such as Figure 2 As shown, a slide rail 15 is fixedly connected to the top of the folding cover plate 14, and a slider 16 is slidably connected to the outside of the slide rail 15. The slider 16 reciprocates and adjusts within the slide rail 15. An elastic connecting rod 17 is slidably connected to the inside of the slider 16, and a spring is connected to the outside of the elastic connecting rod 17. The top of the spring is fixedly connected to the bottom of the slider 16, and the bottom of the spring is fixedly connected to the top of the feed baffle 18. The feed baffle 18 is fixedly connected to the bottom of the elastic connecting rod 17. When the feed baffle 18 slides, it facilitates the dispersion of materials and improves the crushing efficiency.

[0025] Specifically, such as Figure 4 As shown, a snap-fit ​​plate 19 is fixedly connected to the top of the collecting hopper 20, and a handle 21 is fixedly connected to the top of the snap-fit ​​plate 19. The collecting hopper 20 is attached to the front end of the discharge square tube 7. The outer side of the collecting hopper 20 is inclined and attached to the inner wall of the feed box 6. The inner wall of the collecting hopper 20 is provided with multiple holes to facilitate screening of the crushed material.

[0026] In this embodiment: the raw material for copper strip smelting is placed in the feeding frame 8, and then transferred by the impact of the turntable 11. The larger particles of the raw material are screened and fed into the inner side of the shredding roller 13 for crushing. After being screened again, the material is dispersed into the smelting furnace 3 through the discharge square tube 7 for smelting. When the raw material for steel strip smelting is being transported, a reciprocating adjustable feed baffle 18 is set to intermittently stop the material, so that the crushing of the material is more uniform. After two screenings, the incompletely crushed raw material is removed through the collection hopper 20 and poured back into the feeding frame 8 for secondary crushing, which helps to improve the stability of subsequent smelting.

[0027] Specifically, the solution is as follows: When smelting and processing high-strength, high-conductivity copper alloy strip, the raw material for copper strip smelting is first placed in the feeding frame 8. Then, the turntable 11 is rotated by the motor 10. The four elastic telescopic blocks 12 on the inner side of the turntable 11 will collide with the bottom of the feeding frame 8 under the action of centrifugal force. The raw material is transferred to the screening screen 9 by the impact of the turntable 11. The raw material with larger particles is screened out and fed into the inner side of the shredding roller 13 for crushing. Before the raw material enters the inner side of the shredding roller 13 for crushing, the feed baffle 18 is moved back and forth by the slider 16 to facilitate the crushing of the material. Dispersion adjustment is performed to avoid insufficient crushing of raw materials due to accumulation. Small particles are then screened through the screen 9 and fall to the bottom of the feed box 6. The bottom of the feed box 6 is also inclined to facilitate material transfer. The crushed material is then screened through the collection hopper 20 and then dispersed into the melting furnace 3 through the discharge square pipe 7 for melting. Finally, the incompletely crushed raw materials can be removed through the collection hopper 20 by hand handle 21 and poured back into the discharge frame 8 for secondary crushing to improve the stability of subsequent melting. The molten raw materials can be discharged through the discharge pipe 5.
