During this transfer, it is difficult to guide and limit the transfer position, which can easily cause the transfer to sway. This leads to instability in the melting process, affecting the melting rate and reducing the production efficiency of the equipment. Optimization and improvement are needed to address this issue.

Four cleaning rotating rods 7 are provided, which guide and limit the transmission of raw materials. Brushes are provided on the outer side of the cleaning rotating rods 7 to facilitate cleaning the surface of the raw materials. A movable plate 12 is connected to the inner side of the cleaning rotating rods 7, and a scraper 14 is connected to the bottom end of the movable plate 12. The feeding pretreatment assembly is used for pretreatment cleaning of raw materials during oxygen-free copper production; specifically, as shown... Figure 2 As shown, the upper and lower inner walls of the feeding processing frame 3 are both connected to fixed plates 9, and the inner side of the fixed plates 9 is fixedly connected to elastic connectors 10. The fixed plates 9 are fixedly connected to the inner side of the feeding processing frame 3 to limit the positioning position of the elastic connectors 10. The other end of the elastic connectors 10 is fixedly connected to the movable plate 12 to limit the rotation range of the movable plate 12.

[0019] Specifically, such as Figure 3 As shown, a rotating rod 11 is fixedly connected to the middle of the upper and lower inner walls of the feeding processing frame 3. The movable plate 12 is rotatably connected to the outside of the rotating rod 11. The rotating rod 11 is fixedly connected to the upper and lower walls of the feeding processing frame 3 and serves as the middle support for the rotation of the movable plate 12.

[0020] Specifically, such as Figure 3 As shown, an elastic connecting rod 13 is connected through the inner side of the movable plate 12. The bonding scraper 14 is fixedly connected to the bottom end of the elastic connecting rod 13. A spring is connected to the bottom outer side of the elastic connecting rod 13. The upper and lower ends of the spring are fixed between the movable plate 12 and the bonding scraper 14, respectively, for squeezing the bonding scraper 14 to tightly bond the raw material being transported.

[0021] Specifically, such as Figure 2 As shown, a discharge frame 8 is fixedly connected to the inner side of the bottom wall of the feeding processing frame 3. The discharge frame 8 is used to guide and discharge the debris generated during the raw material processing.

[0022] The feeding guide assembly includes a slider 5, which is connected to one side of the top of the furnace box 1. A feeding adjustment frame 15 is connected to the top of the slider 5, and an adjustment pressure roller 19 is connected to the inner side of the feeding adjustment frame 15. The feeding guide assembly is used for slow guidance when oxygen-free copper raw materials are filled.

[0023] Specifically, such as Figure 1 As shown, slide rails 4 are fixedly connected to both sides of the top of the furnace box 1. The slider 5 is slidably connected to the slide rail 4. The sliding of the slider 5 on the slide rail 4 facilitates the control of the orientation of the feeding guide component.

[0024] Specifically, such as Figure 4 As shown, a motor 6 is fixedly installed on the outside of the slider 5. The rotating end of the motor 6 passes through the slider 5 and is connected to a rotating connecting seat 16. The motor 6 is connected to the rotating connecting seat 16 to control the rotation adjustment of the feed adjustment frame 15.

[0025] Specifically, such as Figure 4 As shown, the feed adjustment frame 15 is connected to one side of the rotating connecting seat 16. The bottom inner side of the feed adjustment frame 15 is rotatably connected to a fixed roller 17. The end of the fixed roller 17 is provided with a rotational power to facilitate rotation. The top wall of the feed adjustment frame 15 is slidably connected to a sliding frame 18. The adjusting pressure roller 19 is rotatably connected to the bottom end of the sliding frame 18. The top of the feed adjustment frame 15 is rotatably connected to a rotating screw 20 that is threadedly connected to the sliding frame 18. Rotating the rotating screw 20 can drive the adjusting pressure roller 19 to adjust its height to adapt to the thickness of the raw material and facilitate clamping and positioning.

[0026] In this embodiment: Before the raw material is produced, the debris on the surface of the raw material is scraped and cleaned by setting the limiting transmission of the cleaning rotating rod 7 and the pressing of the sticking scraper 14, so as to reduce the impurities entering the electric furnace. During the filling process of the raw material, the feeding processing frame 3 is used for guiding pre-treatment to achieve the effect of pre-cleaning and avoid impurities from affecting the stability of subsequent clamping. Then, the raw material is transmitted and clamped by the feeding adjustment frame 15, and the feeding angle of the feeding adjustment frame 15 is controlled so that it is slowly filled into the inner melting furnace 2 for melting and processing.

[0027] Specifically, the solution is as follows: When processing oxygen-free copper, before the raw material is transported, it is first processed through the feeding processing frame 3. Four cleaning rotating rods 7 are set up in two sets to clean the surface of the raw material. Then, a movable plate 12 that can be rotated and adjusted within a certain range drives the bonding scraper 14 to bond and squeeze. The rotation range of the movable plate 12 is controlled by the cooperation of the rotating rod 11 and the fixed plate 9 to scrape and clean the debris on the surface of the raw material, allowing the debris to be discharged through the discharge frame 8. Then, when the raw material is filled into the inner melting furnace 2, the pre-cleaned raw material guided by the feeding processing frame 3 is stuck inside the fixed roller 17 and the adjusting pressure roller 19. The position of the adjusting pressure roller 19 is controlled by rotating the rotating screw 20. When the raw material is completely separated from the feeding processing frame 3, the feeding adjusting frame 15 can be rotated by the motor 6. Then, one end of the raw material will slowly move into the inner melting furnace 2 at a certain angle. Then, the fixed roller 17 rotates to continuously push the clamped raw material, allowing the raw material to slowly enter the inner melting furnace 2 for melting.
