Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically to a feeding mechanism for oxygen-free copper continuous casting electrolytic copper. Background Technology

[0002] In the oxygen-free copper vertical continuous casting process, electrolytic copper needs to be continuously added to the melting furnace. Traditional feeding methods typically use sliding plates or tracks. When electrolytic copper slides from the feeding slide (roller conveyor) into the melting furnace, it impacts the molten copper, causing splashing and impacting the refractory material at the furnace bottom. This splashing can burn equipment and personnel, posing a safety hazard. Impact on the furnace lining can cause refractory material to detach, reducing lining life and even leading to furnace leakage risks. Complex electrolytic copper feeding mechanisms, such as robotic arms, operate in high-temperature, dusty environments for extended periods, resulting in a very high failure rate and impacting furnace capacity. The purpose of this invention is to utilize a simple, reliable, and efficient mechanism to control the speed at which electrolytic copper enters the furnace, reducing or even eliminating molten copper splashing and improving furnace lining life.

[0003] Therefore, it is necessary to provide a feeding mechanism for oxygen-free copper continuous casting electrolytic copper to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing technologies, molten copper splashing can cause burns to equipment and personnel, posing a safety hazard. It can also impact the furnace lining, causing refractory material to detach, reducing the furnace lining's lifespan, and even leading to the risk of furnace leakage.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: it includes a frame and a sliding plate installed on the upper end of the frame for receiving and conveying electrolytic copper. Support columns are fixedly installed at both ends of the frame, and rotating arms are rotatably connected to the two support columns. The same end of the two rotating arms is connected to the same moving pressure roller. A driving device is fixedly installed at the lower end of the frame, and the upper end of the driving device cooperates with the moving pressure roller to make the electrolytic copper block pass through slowly. The driving device includes a motor, gear one, gear two, gear three, chain one, chain two, mounting block, lower support roller one, and lower support roller two. The motor is fixedly installed at the bottom of the frame, and the mounting block is fixedly installed on one side of the frame. Gear one is coaxially connected to the output end of the motor. Gear two and gear three are rotatably connected to the mounting block. One end of gear two is connected to gear one via chain one, and the other end of gear two is connected to gear three via chain two. A rotating rod one is coaxially connected to the inner side of gear two. Lower support roller one is fixedly connected to the rotating rod one. A rotating rod two is coaxially connected to the inner side of gear three. Lower support roller two is fixedly connected to the rotating rod two.

[0006] As a preferred embodiment of this utility model, the slide plate is inclined downwards, and the slide plate has an opening. The upper surfaces of the first lower support roller and the second lower support roller pass through the slide plate and are flush with its inner surface.

[0007] As a preferred embodiment of this utility model, the inner surface of the frame is provided with two bearings, and one end of the rotating rod one and the rotating rod two passes through and is rotatably connected to the two bearings.

[0008] In a preferred embodiment of this utility model, the rotating arm is L-shaped, with one end of the rotating arm connected to one end of spring one, the other end of spring one connected to the support column, and the other end of the rotating arm connected to one end of spring two, the other end of spring two connected to the sliding plate.

[0009] As a preferred embodiment of this utility model, the upper end of the slide plate is provided with a roller for receiving electrolytic copper.

[0010] As a preferred embodiment of this utility model, a protective net is provided on the side of the frame near the drive device.

[0011] As a preferred embodiment of this utility model, the lower end of the upper valve hammer is tapered.

[0012] Compared with related technologies, the feeding mechanism for oxygen-free copper continuous casting electrolytic copper provided by this utility model has the following beneficial effects: In this technical solution, electrolytic copper is conveyed from the preheating furnace conveyor chain onto the slide plate, buffered by idler rollers, and then flows along the slide plate towards the gap between the moving pressure roller and the first and second lower support rollers. When the electrolytic copper contacts the first lower support roller, the motor drives gear one to rotate. Under the connection of chains one and two, gears two and three will rotate, which in turn will drive the first and second lower support rollers to rotate respectively. At this time, the rotation speed of the first lower support roller is less than that of the electrolytic copper. At this moment, the first lower support roller performs its first contact with the electrolytic copper. The process involves deceleration. When the electrolytic copper moves to contact the moving pressure roller, the moving pressure roller bounces upwards due to the impact of the electrolytic copper. With the cooperation of spring one and spring two, the elastic potential energy is quickly counteracted, causing the moving pressure roller to fall back onto the surface of the electrolytic copper under its own weight and press it down. Subsequently, the electrolytic copper passes through the lower support roller one and lower support roller two in sequence under the pressure of the moving pressure roller, thereby adjusting the speed at which the electrolytic copper enters the furnace. The speed of the electrolytic copper entering the furnace can be controlled by adjusting the motor speed, and the speed can be adjusted to 200 mm / s.

[0013] The feeding mechanism, in conjunction with the driving device, uses a moving pressure roller. The electrolytic copper undergoes its first deceleration upon contact with the lower support roller 1. Upon contact with the moving pressure roller, the impact of the electrolytic copper causes it to bounce upwards, resulting in a second deceleration. Subsequently, under the pressure of the moving pressure roller, the electrolytic copper passes sequentially through the lower support rollers 1 and 2, thereby regulating the speed at which the electrolytic copper enters the furnace. By adjusting the motor speed, the rotational speeds of the lower support rollers 1 and 2 can be controlled, thus controlling the copper feeding speed. This reduces the splashing of molten copper, preventing burns to equipment and personnel, improving equipment safety, eliminating damage to the furnace lining from impacts, extending furnace lining life, and reducing the risk of furnace leakage.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0018] like Figure 1-3As shown, the present invention discloses a feeding mechanism for continuous casting of oxygen-free copper electrolytic copper, comprising a frame 1 and a sliding plate 2 installed on the upper end of the frame 1 for receiving and conveying electrolytic copper. Support columns 3 are fixedly installed at both ends of the frame 1, and rotating arms 4 are rotatably connected to the two support columns 3. The same end of the two rotating arms 4 is connected to the same moving pressure roller 5. A driving device is fixedly installed at the lower end of the frame 1. The upper end of the driving device cooperates with the moving pressure roller 5 to allow the electrolytic copper block to pass slowly. A protective net 18 is provided on the side of the frame 1 near the driving device to protect the driving device. When the electrolytic copper passes through the moving pressure roller 5, the moving pressure roller 5 is lifted under the impact force, and the front end of the electrolytic copper passes through the gap on the lower surface of the moving pressure roller 5.

[0019] Furthermore, the drive device includes a motor 6, gear 7, gear 8, gear 9, chain 10, chain 21, mounting block 12, lower support roller 13, and lower support roller 214. The motor 6 is fixedly mounted at the bottom of the frame 1, and the mounting block 12 is fixedly mounted on one side of the frame 1. Gear 7 is coaxially connected to the output end of the motor 6. Gear 8 and gear 9 are rotatably connected to the mounting block 12. The motor 6 drives gear 7 to rotate. Since one end of gear 8 is connected to gear 7 via chain 10, the rotation of gear 7 will drive gear 8 to rotate simultaneously. The other end of gear 8 is connected to gear 9 via chain 21. The transmission connection is such that when gear 2 (8) rotates, it drives gear 3 (9) to rotate. A rotating rod 1 is coaxially connected to the inner side of gear 2 (8), and a lower support roller 13 is fixedly connected to the rotating rod 1. A rotating rod 2 is coaxially connected to the inner side of gear 3 (9), and a lower support roller 2 (14) is fixedly connected to the rotating rod 2. Two bearings are provided on the inner surface of the frame 1. One end of rotating rod 1 and rotating rod 2 passes through and is rotatably connected to the two bearings. When gear 2 (8) and gear 3 (9) rotate, they will drive the lower support roller 13 and lower support roller 2 (14) to rotate respectively. When the electrolytic copper moves to the gap between the lower support roller 13, lower support roller 2 (14) and the dynamic pressure roller 5, the speed at which the electrolytic copper enters the furnace is adjusted.

[0020] The slide plate 2 is tilted downwards and has an opening. The upper surfaces of the lower support roller 13 and the lower support roller 2 14 pass through the slide plate 2 and are flush with its inner surface. The upper end of the slide plate 2 is provided with a support roller 17 to receive electrolytic copper. Electrolytic copper is conveyed from the preheating furnace conveyor chain to the slide plate 2, buffered by the support roller 17, and then rushes along the slide plate 2 towards the gap between the dynamic pressure roller 5 and the lower support roller 13 and the lower support roller 2 14. The speed of electrolytic copper entering the furnace is controlled by adjusting the speed of the motor 6. The speed can be adjusted to 200 mm / s to enter the furnace.

[0021] The rotating arm 4 is L-shaped. One end of the rotating arm 4 is connected to one end of spring 15, and the other end of spring 15 is connected to the support column 3. The other end of the rotating arm 4 is connected to one end of spring 2 16, and the other end of spring 2 16 is connected to the slide plate 2. When the electrolytic copper passes through the moving pressure roller 5 and the lower support roller 13 and the lower support roller 2 14, the moving pressure roller 5 will bounce upward under the impact of the electrolytic copper. Under the combined action of spring 15 and spring 2 16, the elastic potential energy is quickly offset, causing the moving pressure roller 5 to fall down under its own weight, and then fall back to the surface of the electrolytic copper and press it down.

[0022] In this technical solution, electrolytic copper is conveyed from the preheating furnace conveyor chain to the slide plate 2, buffered by the idler roller 17, and then flows along the slide plate 2 towards the gap between the moving pressure roller 5 and the lower support roller 13 and lower support roller 2 14. When the electrolytic copper contacts the lower support roller 13, the motor 6 drives the gear 17 to rotate. Under the connection of the chain 10 and the chain 21, the gears 28 and 39 will rotate, which will simultaneously drive the lower support rollers 13 and 24 to rotate respectively. At this time, the rotation speed of the lower support roller 13 is less than that of the electrolytic copper. The copper undergoes its first deceleration. When the electrolytic copper moves to contact the moving pressure roller 5, the moving pressure roller 5 will bounce upwards due to the impact of the electrolytic copper. Under the combined action of spring 15 and spring 26, the elastic potential energy is quickly offset, causing the moving pressure roller 5 to fall back onto the surface of the electrolytic copper and press it down. Subsequently, the electrolytic copper passes through the lower support roller 13 and lower support roller 24 in sequence under the pressure of the moving pressure roller 5, thereby adjusting the speed at which the electrolytic copper enters the furnace. The speed of the electrolytic copper entering the furnace is controlled by adjusting the speed of the motor 6, and the speed can be adjusted to 200 mm / s.

[0023] The feeding mechanism works in conjunction with the drive device via the dynamic pressure roller 5. The electrolytic copper undergoes its first deceleration when it first contacts the lower support roller 13. Upon contact with the dynamic pressure roller 5, the impact of the electrolytic copper causes the roller 5 to bounce upwards, resulting in a second deceleration. Subsequently, under the pressure of the dynamic pressure roller 5, the electrolytic copper passes sequentially through the lower support roller 13 and the lower support roller 2 14, thereby regulating the speed at which the electrolytic copper enters the furnace. By adjusting the speed of the motor 6, the rotational speeds of the lower support roller 13 and the lower support roller 2 14 can be controlled, thus controlling the speed at which the electrolytic copper enters the furnace. This reduces the splashing of molten copper, preventing burns to equipment and personnel, improving equipment safety, eliminating damage to the furnace lining during impact, extending the furnace lining's lifespan, and reducing the risk of furnace leakage.

[0024] 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.
