Description

Technical Field

[0001] This invention belongs to the field of copper conductor production technology, and specifically relates to a raw material processing device for copper conductor production. Background Technology

[0002] The raw material processing for copper conductor production uses electrolytic copper as raw material. Through smelting and purification, plastic processing and surface treatment, copper is transformed into wires, rods or plates that meet the requirements of conductivity and size. Currently, electrolytic copper raw materials are usually in plate form. During the smelting process, the plate raw materials need to be added to the smelting furnace in sequence for smelting. Then, the molten copper is poured into a continuous casting machine to form round billets, square billets or flat billets with a diameter of 8-15mm. In order to ensure the production quality of copper conductors, the molten copper is usually filtered before billet formation to remove impurities.

[0003] Currently, copper molten metal filtration typically employs a three-dimensional mesh structure made of high-temperature resistant ceramic materials such as silicon carbide and zirconium oxide. This mesh is then fixed inside the smelting furnace using flange bolts or welding, physically intercepting and removing impurities such as oxides, slag, and sand particles from the molten copper. However, the three-dimensional porous structure of the ceramic foam mesh easily creates a labyrinth effect, causing impurities to accumulate not only on the surface but also deep within the pores. For welded or bolted meshes, simply rinsing is insufficient to remove impurities from the pores, failing to achieve the desired cleaning effect. Furthermore, for bolted meshes, the high temperature of molten copper (1200-1300℃) causes oxidation at the bolt and flange contact surfaces, forming a hard oxide layer that makes disassembly difficult, increasing the difficulty of cleaning and impacting the processing efficiency of the copper conductor. Summary of the Invention

[0004] The purpose of this invention is to provide a raw material processing device for copper conductor production, which can flexibly disassemble and clean the filter screen, and can also quickly replace the new filter screen without affecting the processing efficiency of copper conductors, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides, for example Figure 1-8The apparatus shown is a raw material processing device for copper conductor production, including a furnace body 1. The furnace body 1 has a melting chamber 8 inside, which is used for copper raw material smelting space. A filter screen 11 is inclinedly arranged at the lower end of the melting chamber 8. One end of the filter screen 11 is inserted into one side of the melting chamber 8, and the other end of the filter screen 11 abuts against one corner of the bottom of the melting chamber 8, so that the filter screen 11 is not fixedly installed, which is convenient for disassembly and assembly.

[0033] A drain port is provided on the side wall of the furnace body 1 located on one side of the filter screen 11. A drain pipe 3 is connected to the drain port for discharging the filtered copper liquid. Heating wires 12 are provided on the inner side of the four sides of the melting chamber 8 and the four sides of the drain port. The heating wires 12 cover the melting chamber 8 and the drain port to prevent the copper liquid from blocking the channel and stabilize the production process. A slag discharge port 15 is provided on the side wall of the furnace body 1 located on the other side of the filter screen 11. A blocking mechanism 9 for controlling the blocking of copper liquid or slag discharge is slidably installed in the slag discharge port 15. A discharge plate 10 is fixed on the furnace body 1 at the slag discharge port 15. A ventilation mechanism 13 for introducing inert gas is provided at the bottom of the melting chamber 8 and at the drain port.

[0034] During smelting, plate-shaped copper raw materials are fed into the melting chamber 8 and heated to 1200-1300℃ to melt into copper liquid. The copper liquid flows through the inclined filter screen 11 under the action of gravity. The filter screen 11 intercepts impurities such as oxides and slag in the copper liquid. The heating wire 12 continues to heat up to prevent the copper liquid in the melting chamber 8 and the drain port from solidifying. After filtration, the copper liquid is introduced into the continuous casting machine through the drain pipe 3. The slag discharge port 15 is opened by adjusting the blocking mechanism 9. The impurities intercepted by the filter screen 11 slide along the inclined filter screen 11 to the slag discharge port 15 and are discharged through the discharge plate 10. Inert gas is introduced to the bottom of the copper liquid through the ventilation mechanism 13 to further remove oxide inclusions in the copper liquid. Through the physical interception of the filter screen 11 and the chemical removal of oxide inclusions by the inert gas, the purity of the copper liquid is improved and the quality of the copper conductor is guaranteed.

[0035] The filter screen 11 has protrusions 112 integrally formed on both sides at one end. The upper side wall of the melting chamber 8 is provided with a slot 17 for the protrusions 112 to slide into. The protrusions 112 can slide into the slot 17 to position one end of the filter screen 11. A round rod 114 is movably inserted into the other end of the filter screen 11, and an arc-shaped hole 113 is provided at the other end of the filter screen 11 for the round rod 114 to be inserted. One side of the round rod 114 passes through the arc-shaped hole 113 and abuts against the inner bottom of the melting chamber 8. The depth of the arc-shaped hole 113 is greater than two-thirds of the diameter of the round rod 114 to ensure that the round rod 114 does not fall out and can be flexibly removed.

[0036] When installing the filter screen 11, first insert the round rod 114 into the arc-shaped hole 113, then insert the end of the filter screen 11 with the protrusion 112 into the slot 17 of the melting chamber 8, so that the round rod 114 touches the bottom of the melting chamber 8, and moves along the bottom of the melting chamber 8 to the corner opposite the protrusion 112, thus completing the support and positioning of the filter screen 11. No tools are required, and the filter screen 11 can be installed and removed manually, solving the problem of traditional bolted filter screens 11 being difficult to remove due to oxidation. The round rod 114 can reduce the friction when the filter screen 11 moves in the melting chamber 8, and at the same time can block the copper liquid, making it easier for the copper liquid to flow out of the drain port through the filter screen 11.

[0037] The filter screen 11 includes an orifice-shaped frame 111 and a mesh 115. The mesh 115 has an inverted T-shaped cross-section. One side of the orifice-shaped frame 111 has a slot for the mesh 115 to be fitted. The mesh 115 is fixed inside the slot by bolts 116. The bolts 116 only connect the mesh 115 to the frame and do not contact the furnace body 1. The orifice-shaped frame 111 provides structural support. The lateral part of the inverted T-shaped mesh 115 is held in the slot to prevent the mesh 115 from falling off due to the impact of molten copper. The pores of the mesh 115 intercept impurities. The mesh 115 can be replaced individually by unscrewing the bolts 116. It is not necessary to replace the entire filter screen 11 frame. Only the worn mesh 115 needs to be replaced, and the entire filter screen 11 does not need to be replaced, thus saving raw material costs.

[0038] The ventilation mechanism 13 includes a permeable brick 134 embedded in the bottom of the melting chamber 8 and the bottom of the drain port, and an air inlet pipe 131 connected to the bottom of the furnace body 1. One end of the air inlet pipe 131 is equipped with a solenoid valve, and the other end of the air inlet pipe 131 is connected to a branch pipe 132. Multiple air outlet pipes 133 are provided on the branch pipe 132. One end of the air outlet pipe 133 abuts against one side of the permeable brick 134, so that the gas passes through the permeable brick 134 and enters the interior of the melting chamber 8.

[0039] When inert gas is introduced, the solenoid valve is opened, and the inert gas enters the branch pipe 132 through the inlet pipe 131. Inert gases such as nitrogen and argon are evenly distributed to the permeable brick 134 through multiple outlet pipes 133. The inert gas passes through the permeable brick 134 and flows upward from the bottom of the copper liquid, reacting with or carrying oxide inclusions in the copper liquid to the surface, such as cuprous oxide. Finally, it is intercepted by the filter screen 11. The inert gas diffuses from the bottom, making more sufficient contact with the copper liquid, effectively removing oxide inclusions and reducing the loss of conductivity of the copper conductor. The combination of multiple outlet pipes 133 and permeable bricks 134 avoids local gas accumulation that could cause copper liquid to splash, ensuring production safety. The solenoid valve can adjust the gas flow rate and on / off state, avoiding waste of inert gas and adapting to different smelting volume requirements.

[0040] The blocking mechanism 9 includes a fixed plate 91 fixed to the outer wall of the furnace body 1 and a baffle 95 slidably connected to the slag discharge port 15. A rotating rod 93 is rotatably mounted on the fixed plate 91, and a pull rope is wound around the outer wall of the rotating rod 93. A movable cavity 16 for the baffle 95 to slide is opened at the slag discharge port 15. One end of the pull rope passes through one side of the movable cavity 16 and is fixed to the baffle 95. A second motor 92 is installed at one end of the rotating rod 93. A fixing ring 96 for fixing the pull rope is fixed to the upper end of the baffle 95. A device for fixing the pull rope is rotatably mounted on the upper end of the movable cavity 16. The guide rod 94 has a through hole on one side of the moving cavity 16 for the pull rope to pass through. The second motor 92 drives the rotating rod 93 to rotate, and the pull rope is wound on the rotating rod 93, pulling the baffle 95 to move upward along the moving cavity 16, opening the slag discharge port 15. Impurities slide out along the inclined filter screen 11. When the discharge port is closed, the second motor 92 drives the rotating rod 93 to rotate in the opposite direction, the pull rope loosens, and the baffle 95 moves downward under the action of gravity, closing the slag discharge port 15 and preventing copper liquid leakage. Slag discharge can be controlled by simply rotating the rotating rod 93. There is no need to manually touch the high-temperature baffle 95 to avoid burns.

[0041] The upper end of the melting chamber 8 is funnel-shaped. A cover plate 2 is hinged to one side of the upper end of the melting chamber 8. A placement groove 14 is provided at the upper end of the melting chamber 8 for the cover plate 2 to be placed and closed. When the cover plate 2 is closed, the upper end of the melting chamber 8 forms a feed port 7 for feeding plate-shaped copper materials. One side of the feed port 7 is inclined. When the cover plate 2 is closed, the plate-shaped copper materials are fed into the melting chamber 8 along the feed port 7 to prevent the material from shifting. When the cover plate 2 is open, it is inclined at the upper end of the melting chamber 8 to guide the material when feeding plate-shaped copper materials, such as block-shaped and fragmented copper raw materials. Non-plate-shaped materials slide into the melting chamber 8 along the inclined cover plate 2 to prevent the material from scattering outside the furnace body 1. The feeding structure needs to be changed to handle copper raw materials of different shapes such as plate-shaped, block-shaped, and fragmented materials, thus improving the versatility of the device.

[0042] When the cover plate 2 is closed, it is embedded in the placement groove 14 to reduce heat loss in the melting chamber 8 and prevent external dust and impurities from entering. When the cover plate 2 is closed, heat loss is reduced, smelting energy consumption is reduced, and impurities are prevented from contaminating the copper liquid. The tilted cover plate 2 guides the raw materials to slide in, preventing hands from approaching the high-temperature melting chamber 8 when manually feeding materials, thus reducing the risk of burns.

[0043] To facilitate the addition of materials to the melting chamber 8, the present invention also includes a feeding mechanism 4 installed on one side of the feed inlet 7. A scissor lift 5 is installed at the lower end of the feeding mechanism 4. The scissor lift 5 can adjust the height of the feeding mechanism 4 to adapt to different feeding requirements. A collection box 6 is fixed at the lower end of the scissor lift 5. One side of the collection box 6 is connected to the discharge plate 10. The collection box 6 is used to receive impurities discharged from the slag discharge port 15. A cooling mechanism, such as a cooling water pipe and a heat sink, is installed inside the side wall of the collection box 6. A door is installed on one side of the collection box 6. By opening and closing the door, it is easy to clean impurities.

[0044] During feeding, the tilt angle and height of the feeding mechanism 4 are adjusted by the scissor lift 5 according to the height of the feed inlet 7 of the melting chamber 8, ensuring that the raw materials enter the melting chamber 8 accurately. The high-temperature impurities discharged from the slag discharge port 15 slide into the collection box 6 through the discharge plate 10. The cooling mechanism cools down the impurities to prevent the collection box 6 from overheating or the impurities from clumping. After the impurities are cooled, they can be removed by opening the box door without contacting the high-temperature parts. The height adjustment of the scissor lift 5, together with the feeding mechanism 4, realizes automatic feeding, reduces manual handling, and reduces labor intensity. The cooling mechanism prevents high-temperature impurities from burning operators or igniting surrounding items. The collection box 6 centrally stores the materials for easy subsequent processing. The height of the scissor lift 5 can be flexibly adjusted to adapt to different workshop layouts and smelting furnace specifications.

[0045] The feeding mechanism 4 includes a U-shaped frame 41. Multiple rolling rods 46 are rotatably mounted on the bottom of the U-shaped frame 41. The multiple rolling rods 46 are used to reduce the friction between the plate-shaped copper raw material and the U-shaped frame 41. A limiting mechanism 47 for feeding multiple plate-shaped copper raw materials one by one is installed on the U-shaped frame 41 located at the feed inlet 7. A buffer mechanism 44 for reducing the impact of the plate-shaped copper raw material on the filter screen 11 is installed above the limiting mechanism 47. A push plate 42 for pushing the plate-shaped copper raw material to move is installed at the other end of the U-shaped frame 41. The push plate 42 is connected to the U-shaped frame 41 through a moving mechanism 43.

[0046] Plate-shaped copper raw materials are stacked on the rolling rods 46 of the U-shaped frame. The rolling rods 46 reduce the frictional resistance during material movement. The reduced friction makes it easier for the pusher plate 42 to move the raw materials, preventing jamming. The moving mechanism 43 drives the pusher plate 42 to slide along the U-shaped frame, pushing the raw materials towards the feed inlet 7. The limiting mechanism 47 ensures that only one raw material enters the feed inlet 7 at a time, preventing multiple raw materials from entering the melting chamber 8 simultaneously, thus avoiding overloading the melting chamber 8 or clogging the filter screen 11. The buffer mechanism 44 slows down the speed at which the raw materials enter the melting chamber 8, preventing impact on the filter screen 11, reducing the impact of the raw materials on the filter screen 11, and extending the service life of the filter screen 11.

[0047] The limiting mechanism 47 includes a rotating shaft 471 rotatably mounted on a U-shaped frame 41. Multiple limiting plates 472 are fixed at equal angles on the outer wall of the rotating shaft 471. The number of limiting plates 472 is adapted to the thickness of the raw material. One of the limiting plates 472 is inserted into the gap between two adjacent plate-shaped copper raw materials. Under normal conditions, one limiting plate 472 is inserted into the gap between two adjacent plate-shaped copper raw materials to prevent the movement of subsequent raw materials. During a single feeding, when the push plate 42 pushes the foremost raw material to move, the raw material drives the limiting plate 472 to rotate around the rotating shaft 471, causing the limiting plate 472 inserted into the gap to disengage. The foremost raw material enters the feed port 7. After the previous raw material enters, the rotating shaft 471 is reset under the action of gravity or an auxiliary spring. The next limiting plate 472 is inserted into the gap between the next two raw materials to prevent their movement, thus realizing feeding one material at a time.

[0048] The buffer mechanism 44 includes mounting seats 441 fixed on both sides of the U-shaped frame 41 and a powerful electromagnet 444 located at the end of the U-shaped frame 41. A rotating rod 442 is rotatably mounted inside the mounting seat 441. A traction rope 443 is wound around the outer wall of the rotating rod 442. One end of the traction rope 443 on both sides is fixed to the powerful electromagnet 444. A torsion spring for restoring the traction rope 443 after stretching is installed on the rotating rod 442. The raw material moves to the U-shaped frame 41. When the material is at the end of the frame, the powerful electromagnet 444 is energized to attract the raw material, slowing down the movement speed of the raw material and avoiding hard impact that could deform or damage the filter screen 11. When the raw material is attracted, the traction rope 443 pulls the rotating rod 442 to rotate, and the torsion spring stores energy. After the raw material enters the melting chamber 8, the powerful electromagnet 444 is de-energized, the torsion spring drives the rotating rod 442 to reset, and the traction rope 443 is retracted. The attraction force of the powerful electromagnet 444 is adjustable to adapt to plate-shaped raw materials of different weights. The torsion spring ensures that the traction rope 443 and the powerful electromagnet 444 are reset without manual intervention.

[0049] The moving mechanism 43 includes lead screws 432 rotatably mounted on both sides of the U-shaped frame 41. A connecting rod 433 is threaded onto the lead screw 432. One end of the connecting rod 433 is fixed to the push plate 42, and a first motor 431 is mounted on one end of the lead screw 432. Protrusions 421 are fixed to opposite sides of the push plate 42. Slide grooves 45 are provided on the inner walls of both sides of the U-shaped frame 41 for the protrusions 421 to slide. The first motor 431 drives the lead screw 432 to rotate, and the connecting rod 433 moves axially along the lead screw 432, causing the push plate 42 to move synchronously. This ensures a uniform moving speed for the push plate 42, preventing material jamming or deviation. When the push plate 42 moves, the protrusions 421 slide along the slide grooves 45 to prevent the push plate 42 from deviating, ensuring that the material enters the feed inlet 7 in a straight line, preventing the push plate 42 from tilting, ensuring accurate feeding position, eliminating the need for manual pushing, reducing labor intensity, and improving feeding efficiency.
