Description

Technical Field

[0001] This utility model relates to the technical field of melt purification, and in particular to a melt purification mechanism for oxygen-free copper rod continuous casting units. Background Technology

[0002] With the development of technology, the wire and cable industry has increasingly higher requirements for the quality of copper rods used in electrical applications. Oxygen-free copper rods have good conductivity, ductility, airtightness, and low hydrogen embrittlement tendency, and have been widely favored in the wire and cable industry. In the continuous casting production process of oxygen-free copper rods, melt purification is a key step to ensure the high purity and high performance of the copper rods. At present, flux purification process is widely used, which removes inclusions and gases by adding special purifying agents to the high-temperature copper melt. When adding the purification solvent to the melt furnace, the temperature around the furnace is high. If workers add the solvent directly, the high temperature will burn the workers, resulting in poor stability in use.

[0003] Existing feeding methods, such as the spiral feeding device used in a melt purification device for oxygen-free copper rod processing (patent number CN219907805U), have the advantages of high efficiency and strong continuity in continuous feeding processes. However, for intermittent or single-time feeding, there are problems such as uneven feeding and inaccurate metering. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a melt purification mechanism for an oxygen-free copper rod continuous casting unit that provides uniform feeding and accurate single-feeding measurement.

[0005] The melt purification mechanism of the oxygen-free copper rod continuous casting unit of this utility model includes: The storage box is independently and fixedly installed, and an addition funnel is provided at the bottom of the storage box; The adapter box is installed on the adding funnel, and a slot is provided at the connection between the adapter box and the adding funnel; The transfer pipe is coaxially installed at one end of the adapter box, and the tail end of the transfer pipe is provided with a discharge port. The transfer component is slidably connected to the transfer box and the transfer pipe respectively, and the transfer component is provided with a through groove; Limiting mechanisms are installed at the connections between the transfer components and the transfer box and transfer pipe; The power mechanism, mounted on the adapter box, is used to drive the working position of the transfer component. The flipping mechanism, installed on the adapter box, is used to adjust the direction of the through groove of the transfer component.

[0006] As a preferred embodiment of this utility model, the limiting mechanism includes: A hollow shaft is rotatably mounted in the shaft hole of the adapter box; The drive shaft is connected to the cavity of the hollow shaft and rotates synchronously with the hollow shaft. The drive shaft is slidably connected along the length of the hollow shaft. The guide is installed in the cavity of the transfer tube and is slidably connected to the positioning groove of the transfer component.

[0007] As a preferred embodiment of this utility model, a baffle plate is coaxially mounted on the hollow shaft. The baffle plate is slidably connected to the positioning groove of the transfer component. The baffle plate is used to seal the slot of the transfer box when the through groove of the transfer component faces downward.

[0008] In a preferred embodiment of this utility model, at least one of the transfer component, the guide component, the hollow shaft, and the transmission shaft is in a state of mutual connection.

[0009] As a preferred embodiment of this utility model, the flipping mechanism includes: The connecting shaft is rotatably installed in the slot of the adapter box, and a drive gear is provided on the connecting shaft; The driven gear is coaxially mounted on a hollow shaft, and the driving gear meshes with the driven gear. The servo motor is mounted on the adapter box, and the output end of the servo motor is installed in conjunction with the connecting shaft.

[0010] As a preferred embodiment of this utility model, the servo motor drives the hollow shaft to rotate 180° by meshing the driving gear and the driven gear during a single start.

[0011] As a preferred embodiment of this utility model, the power mechanism includes: The threaded rod is coaxially and rotatably installed in the inner cavity of the transfer tube; The threaded tube is coaxially installed in the slot cavity of the transfer component, and the threaded rod is installed in conjunction with the threaded tube.

[0012] As a preferred embodiment of this utility model, a protective box is installed on the adapter box, and the power mechanism is located inside the protective box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The storage box serves as the storage and supply unit for the purifying agent. It supplies the transfer box to the transfer box through a funnel added to the bottom. The transfer box and the transfer pipe cooperate to form a conveying channel. The through groove on the transfer component can realize the quantitative reception and transfer of the purifying agent. By selecting transfer components with different volumes, the amount added at one time can be changed. The quantitative addition is realized in conjunction with the power mechanism. The flipping mechanism can adjust the direction of the through groove of the transfer component. That is, when the through groove is inside the transfer box, the through groove is connected to the slot of the transfer box, and the purifying agent flows into the inner cavity of the transfer component. After the transfer component flips, the through groove is connected to the outlet of the transfer pipe. At this time, the purifying agent flows out in the transfer component.

The overall structure realizes the automatic quantitative addition of the purifying agent through mechanical transmission, keeping the operator away from the high temperature environment. At the same time, quantitative addition ensures the stability of the purification effect. Attached Figure Description

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figures 1 to 5 As shown, this embodiment provides a melt purification mechanism for an oxygen-free copper rod continuous casting unit, including: Storage tank 1 is a storage and supply unit for the purifying agent. It is independently and fixedly installed on the side support of the continuous casting unit. An addition funnel 2 is provided at the bottom of storage tank 1. The adapter box 3 is installed on the adding funnel 2, and a slot is provided at the connection between the adapter box 3 and the adding funnel 2; The transfer pipe 4 is coaxially installed at one end of the adapter box 3, and the tail end of the transfer pipe 4 is provided with a discharge port. The transfer component 5 is the core execution component for realizing the quantitative transfer of the purifying agent. It is slidably connected to the transfer box 3 and the transfer pipe 4 respectively. The transfer component 5 is provided with a through groove. Limiting mechanisms 6 are provided at the connection points between the transfer component 5 and the transfer box 3 and the transfer pipe 4; The power mechanism 7 is installed on the adapter box 3 and is used to drive the working position of the transfer component 5. The flipping mechanism 8 is installed on the adapter box 3. The flipping mechanism 8 is used to adjust the direction of the through groove of the transfer component 5. In this embodiment, the storage tank 1 serves as the storage and supply unit for the purifying agent. It supplies the purifying agent to the transfer tank 3 through the funnel 2 at the bottom. The transfer tank 3 and the transfer pipe 4 cooperate to form a conveying channel. The through groove on the transfer component 5 can realize the quantitative reception and transfer of the purifying agent. By selecting transfer components 5 with different volumes, the amount added at one time can be changed. The quantitative addition is realized in conjunction with the power mechanism 7. The flipping mechanism 8 can adjust the direction of the through groove of the transfer component 5. That is, when the through groove is inside the transfer tank 3, the through groove is connected to the slot of the transfer tank 3, and the purifying agent flows into the inner cavity of the transfer component 5. After the transfer component 5 is flipped, the through groove is connected to the outlet of the transfer pipe 4. At this time, the purifying agent flows out in the transfer component 5. The limiting mechanism 6 at the connection between the transfer component 5 and the transfer tank 3 and the transfer pipe 4 ensures the stability of the transfer process and avoids leakage of the purifying agent at the slot of the transfer tank 3. The overall structure realizes the automatic quantitative addition of the purifying agent through mechanical transmission, keeping the operator away from the high temperature environment. At the same time, quantitative addition ensures the stability of the purification effect.

[0018] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the limiting mechanism 6 includes: Hollow shaft 61 is rotatably mounted in the shaft hole of adapter box 3; The drive shaft 62 is connected to the shaft cavity of the hollow shaft 61 and rotates synchronously with the hollow shaft 61. The drive shaft 62 is slidably connected along the length of the hollow shaft 61. The guide 63 is installed in the cavity of the transfer tube 4, and the guide 63 is slidably connected to the positioning groove of the transfer component 5; A baffle plate 64 is coaxially mounted on the hollow shaft 61. The baffle plate 64 is slidably connected to the positioning groove of the transfer component 5. The baffle plate 64 is used to seal the slot of the transfer box 3 when the through groove of the transfer component 5 is facing downward. At least one of the following components—transfer component 5, guide component 63, hollow shaft 61, and drive shaft 62—is in a state of mutual connection. In this embodiment, the drive shaft 62 rotates with the hollow shaft 61 to adjust the direction of the through groove of the transfer component 5, thereby ensuring the alignment of the transfer component 5 with the slot of the transfer box 3. The drive shaft 62 and the hollow shaft 61 are slidably connected along the length direction so that the movement of the transfer component 5 will not cause obstruction. The guide 63 is slidably connected with the positioning groove of the transfer component 5 so that the transfer component 5 will not flip when it is displaced, thereby ensuring that the slot of the transfer component 5 is aligned with the outlet of the transfer pipe 4, and ensuring the transfer of additives into and out of the inner cavity of the transfer component 5. The baffle 64 on the hollow shaft 61 seals the slot of the transfer box 3 when the through groove of the transfer component 5 is facing down, preventing the purifying agent from leaking. The design of at least one of the following connections, namely the transfer component 5 and the guide 63, and the hollow shaft 61 and the drive shaft 62, ensures that the rotation of the transfer component 5 is always in a restricted state, ensuring the stability of the transfer.

[0019] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the flipping mechanism 8 includes: The connecting shaft 81 is rotatably installed in the slot of the adapter box 3, and the connecting shaft 81 is provided with a drive gear 82; Driven gear 83 is coaxially mounted on hollow shaft 61, and driving gear 82 is meshed with driven gear 83; Servo motor 84 is mounted on adapter box 3, and the output end of servo motor 84 is installed in conjunction with connecting shaft 81. The servo motor 84, upon a single start, drives the hollow shaft 61 to rotate 180° by meshing the drive gear 82 and the driven gear 83. In this embodiment, the servo motor 84 of the flipping mechanism 8 is mounted on the adapter box 3. Its output end drives the connecting shaft 81 to rotate. Through the meshing transmission of the driving gear 82 and the driven gear 83, the hollow shaft 61 is precisely driven to flip the transfer component 5 by 180°, realizing the precise switching of the slot direction of the transfer component 5, that is, from being connected to the slot of the adapter box 3 to being connected to the outlet of the transfer pipe 4. The stable output of the servo motor 84 ensures the consistency of a single flipping action, making the quantitative transfer process of the purifying agent reliable and orderly, improving the automation level of the mechanism, and ensuring the efficiency of quantitative addition.

[0020] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the power mechanism 7 includes: The threaded rod 71 is coaxially and rotatably installed in the inner cavity of the transfer tube 4; The threaded tube 72 is coaxially installed in the groove of the transfer component 5, and the threaded rod 71 is installed in conjunction with the threaded tube 72. The power motor 73 is mounted on the adapter box 3. Both the output end of the power motor 73 and the threaded rod 71 are equipped with transmission gears 74, and the two transmission gears 74 are meshed and connected. The adapter box 3 is equipped with a protective box 75, and the power mechanism 7 is located inside the protective box 75; In this embodiment, the power motor 73 of the power mechanism 7 drives the threaded rod 71 to rotate through two meshing transmission gears 74. The threaded rod 71 cooperates with the threaded tube 72 in the groove of the transfer component 5, converting the rotational motion into the linear sliding of the transfer component 5, realizing the precise adjustment of its working position, and ensuring the stable docking of the transfer component 5 with the transfer box 3 and the transfer tube 4. The protective box 75 on the transfer box 3 completely encloses the power mechanism 7, which can effectively prevent external dust and impurities from entering, avoiding them from affecting the gear meshing accuracy or the stability of the cooperation between the threaded rod 71 and the threaded tube 72. At the same time, it protects the operator from injury from mechanical transmission components. The overall structure takes into account both driving accuracy and protection effect, improving the reliability and safety of the mechanism operation.
