Description

Technical Field

[0001] The invention relates to the technical field of copper rod smelting, in particular to a melting furnace for low-oxygen regeneration copper rod smelting. Background Art

[0002] The industrial frequency induction furnace is an induction furnace that uses industrial frequency current (50 or 60 Hz) as power supply. The industrial frequency induction furnace has developed into a widely used smelting equipment. It can also be used to generate oxygen-free copper rods. The production process of oxygen-free copper rods is: cathode copper plate - melting furnace - transition chamber - insulation furnace - crystallizer - traction machine - automatic speed regulating device - wire take-up machine - finished product. The cathode copper is directly added to the melting furnace of the upper lead combination furnace, and melted into copper liquid after industrial frequency induction. After melting, the copper liquid will automatically and smoothly flow into the insulation furnace through the transition chamber and pass through the charcoal covering the surface, so that the copper liquid has a stable reduction and deoxidation process. After reduction, the copper liquid passes through the crystallizer in the continuous casting machine in the insulation furnace to quickly crystallize the copper liquid into a cast rod, and the cast rod is pulled upward through the two pairs of traction rollers in the continuous casting machine. After the cast rod is pulled out from the traction mechanism of the continuous casting machine, it is introduced into the wire take-up machine through the guide wheel frame and the automatic speed regulating device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] See also Figure 1-Figure 9 The embodiment of the present invention provides a technical solution: a melting furnace for low-oxygen regenerated copper rod smelting, comprising a furnace body 1, the furnace body 1 comprising a smelting zone 101 and a holding zone 102, the smelting zone 101 and the holding zone 102 are separated by a perforated partition, a W-type inductor is arranged at the bottom of the smelting zone 101, the W-type inductor is used to smelt electrolytic copper, an O-type inductor is arranged at the bottom of the holding zone 102, the O-type inductor is used to keep the copper liquid warm; a closing component for closing a feed port is arranged at the top of the smelting zone 101, and an insertion hole for installing a crystallizer is arranged at the top of the holding zone 102; a feeding component is arranged at the top of the furnace body 1, and the feeding component is arranged on the top of the closing component through a packaging shell 2.

[0031] Specifically, the closing assembly includes a first docking plate 3 and a second docking plate 4, both sides of the first docking plate 3 are fixedly connected with a first rack 5, both sides of the second docking plate 4 are fixedly connected with a second rack 6, the first rack 5 and the second rack 6 located on the same side are both meshed with a spur gear 7, and the spur gear 7 is movably connected to the furnace body 1 through a short shaft; an electric push rod 8 is fixedly connected to the top of the furnace body 1, and the output shaft of the electric push rod 8 movably passes through the packaging shell 2 and is fixedly connected to the first docking plate 3, the packaging shell 2 is fixedly connected to the top of the furnace body 1, the first docking plate 3 and the second docking plate 4 are both arranged inside the packaging shell 2, and the top of the packaging shell 2 has an opening; the top of the furnace body 1 is fixedly connected to a limit rod 9, and the first docking plate 3 and the second docking plate 4 are both movably sleeved on the surface of the limit rod 9.

[0032] Specifically, a closing plate 10 is connected to the top of the encapsulation shell 2, a stirring motor 11 is fixedly connected to the top of the closing plate 10, the end of the output shaft of the stirring motor 11 movably passes through the closing plate 10 and is fixedly connected to one end of a stirring rod 12, a surface array of the stirring rod 12 is fixedly connected to a plurality of inclined rods 13; the surfaces of the first docking plate 3 and the second docking plate 4 are both provided with semicircular grooves 14, and the two semicircular grooves are both movably connected to the surface of the stirring rod 12.

[0033] In this embodiment, the electric push rod 8 contracts to drive the first docking plate 3 to move. The first docking plate 3 rotates the spur gear 7 through the first rack 5, so that the second rack 6 drives the second docking plate 4 to move, thereby realizing the separation of the first docking plate 3 and the second docking plate 4. The feed port on the top of the furnace body 1 is opened. During the movement of the first docking plate 3 and the second docking plate 4, the limit rod 9 can play a guiding and limiting role.

[0034] The melted copper liquid is separated by a perforated partition and enters the insulation zone 102, and the copper liquid in the insulation zone 102 can be drawn out through a crystallizer. Waste foil or other additives can be added during the smelting of the copper liquid, and stirring and mixing are required. When the first docking plate 3 and the second docking plate 4 are separated, the stirring rod 12 is inserted into the interior of the furnace body 1, and the closing plate 10 is fixed to the top of the packaging shell 2 by bolts. After the stirring motor 11 is powered on, the stirring rod 12 can drive the inclined rod 13 to rotate, thereby stirring, and at the same time, it can also facilitate the unmelted electrolytic copper to be heated evenly and melt quickly.

[0035] Specifically, an anti-falling mesh plate 15 is fixedly connected between any two adjacent inclined rods 13 , and a surface of the anti-falling mesh plate 15 is fixedly connected to a surface of the stirring rod 12 .

[0036] In this embodiment, an anti-falling mesh plate 15 is fixedly connected between any two adjacent inclined rods 13. The anti-falling mesh plate 15 can prevent the electrolytic copper raw materials from falling directly to the bottom of the furnace body 1 when the electrolytic copper raw materials are manually or automatically delivered, thereby damaging the sensor at the bottom. The anti-falling mesh plate 15 is positioned close to the sensor to achieve melting.

[0037] Specifically, the surface of the stirring rod 12 is connected to an anti-friction bearing 16, the surfaces of the first docking plate 3 and the second docking plate 4 are movably connected to a sealing plate 17, and the surfaces of the first docking plate 3 and the second docking plate 4 are fixedly connected to a fixing member 18; the surface of the fixing member 18 is fixedly connected to a connecting spring 19, and the end of the connecting spring 19 away from the fixing member 18 is fixedly connected to the sealing plate 17, and the surface of the sealing plate 17 is movably connected to the surface of the anti-friction bearing 16.

[0038] Specifically, a guide rod 29 is fixedly connected to the surface of the sealing plate 17 . The guide rod 29 movably passes through the fixing member 18 . The fixing member 18 is movably connected to the sealing plate 17 .

[0039] In this embodiment, during the use of the stirring rod 12, the sealing plate will squeeze the stirring rod 12, and when the stirring rod 12 rotates, the sealing plate 17 will cause wear to the stirring rod 12. Therefore, an anti-wear bearing 16 is connected to the surface of the stirring rod 12, and the sealing plate 17 is connected to the anti-wear bearing 16 to avoid direct connection with the stirring rod 12, thereby reducing wear.

[0040] Specifically, the feeding assembly includes a docking orifice plate 20, which is connected to the top of the packaging shell 2, and a cutting box 21 is connected to the top of the docking orifice plate 20. The interior of the cutting box 21 is provided with a first cutting roller 22 and a second cutting roller 23. The first cutting roller 22 is used for longitudinal cutting to cut the electrolytic copper plate into strips, and the second cutting roller 23 is used for transverse cutting to cut the strip-shaped electrolytic copper plate into blocks; the first cutting roller 22 is located on the top of the second cutting roller 23, and the first cutting roller 22 and the second cutting roller 23 are both driven by a driving motor.

[0041] Specifically, a limiting hole 24 is provided inside the cutting box 21 between the first cutting roller 22 and the second cutting roller 23 , and the limiting hole 24 is used to limit the strip-shaped electrolytic copper plate.

[0042] In this embodiment, when automatic feeding is performed, the docking hole plate 20 is installed on the packaging shell 2 by bolts, and the docking hole plate 20 is docked with the closing plate 10 to seal the top of the packaging shell 2. The electrolytic copper plate is sent into the cutting box 21, and the first cutting roller 22 cuts the material longitudinally to cut the electrolytic copper plate into strips. The strip-shaped electrolytic copper plate then passes through the limiting hole 24 to prevent deviation after cutting, and then passes through the second cutting roller 23 to cut the strip-shaped electrolytic copper plate into blocks. Then the block electrolytic copper plate falls into the interior of the packaging shell 2. The bottom of the docking hole plate 20 is fixedly connected with a guide shell, which can guide the block electrolytic copper plate to the top opening of the furnace body 1.

[0043] Specifically, an exhauster 25 is fixedly connected to the surface of the cutting box 21 , and an air supply box 26 is fixedly connected to the surface of the closing plate 10 , and the air supply box 26 stores inert gas inside.

[0044] In this embodiment, in order to better prevent oxidation, an inert atmosphere can be formed inside the packaging shell 2, that is, inert gas is flushed into the interior of the packaging shell 2 through the air supply box 26. For the convenience of recycling, an exhaust fan 25 can be fixedly connected to the surface of the cutting box 21, and the collection is carried out through an external collection device, so that the interior of the packaging shell 2 always maintains an inert atmosphere.

[0045] Specifically, a first rubber strip 27 is fixedly connected to the surface of the closing plate 10 , and a second rubber strip 28 is fixedly connected to the surface of the docking hole plate 20 . The first rubber strip 27 is movably connected to the second rubber strip 28 .

[0046] In this embodiment, the first rubber strip 27 and the second rubber strip 28 can prevent air leakage and avoid excessive leakage of inert gas to cause waste.

[0047] The outer shell of furnace body 1 is a steel structure, and the interior is built with refractory bricks, insulation bricks, silicon ramming materials and insulation materials; the furnace frame supports the entire furnace and is fixed on the floor foundation; the sensor is composed of an outer shell, a coil, a water jacket, a square iron core and a melting groove. The primary of the high-voltage side of the sensor is composed of a coil. A melting sensor adopts a 450KW three-phase balanced autotransformer, and the voltage can be from 90V to 420V, with 10 gears of contact-type stepped electric voltage regulation. The insulation furnace sensor adopts a 150KW three-phase autotransformer with a 150KW sensor, and the voltage can be from 90V to 380V, and the PLC program controls the contact-type stepped automatic voltage regulation. The low-voltage secondary of the inductor is composed of a short-circuited coil melting groove. After power is turned on, under the action of the electromagnetic inductor, low voltage and high current are generated inside the melting groove, so that the melting groove is melted and the added electrolytic copper is melted into copper liquid after the melting groove is melted. The melting furnace inductor adopts a W-type inductor "W"-type connected melting groove. The "W" inductor has the characteristics of high melting rate and low power consumption.

[0048] It should be noted that during the use of the "W"-shaped connected melting groove, the melted melting groove mold merges with the copper liquid in the melting furnace cavity. The temperature of the copper liquid in the W-shaped melting groove is high, and the temperature of the copper liquid in the melting furnace cavity is low. At this time, the temperature of the copper liquid in the W-shaped melting groove differs from the temperature of the copper liquid in the melting furnace cavity by 10°C-20°C. The copper liquid with low temperature has high density and emerges from the melting furnace cavity to the middle position of the W-shaped melting groove and enters the W-shaped melting groove. Under the action of the magnetic induction current generated by the coil, the copper liquid in the W-shaped melting groove gradually heats up, and the copper liquid with high temperature has low density and is sprayed into the melting furnace cavity from the channels on both sides of the W-shaped melting groove, thereby achieving a self-stirring effect and allowing the slag in the melting groove to be washed away.

[0049] The feeding can be done manually or automatically. When manual feeding is used, the cut electrolytic copper needs to be prepared in advance, the electric push rod 8 contracts, drives the first docking plate 3 to move, the first docking plate 3 rotates the spur gear 7 through the first rack 5, so that the second rack 6 drives the second docking plate 4 to move, the first docking plate 3 and the second docking plate 4 are separated, and the feeding port on the top of the furnace body 1 is opened. During the movement of the first docking plate 3 and the second docking plate 4, the limit rod 9 can play a guiding and limiting role.

[0050] The melted copper liquid is separated by a perforated partition and enters the insulation zone 102, and the copper liquid in the insulation zone 102 can be drawn out through a crystallizer. Waste foil or other additives can be added during the smelting of the copper liquid, and stirring and mixing are required. When the first docking plate 3 and the second docking plate 4 are separated, the stirring rod 12 is inserted into the interior of the furnace body 1, and the closing plate 10 is fixed to the top of the packaging shell 2 by bolts. After the stirring motor 11 is powered on, the stirring rod 12 can drive the inclined rod 13 to rotate, thereby stirring, and at the same time, it can also facilitate the unmelted electrolytic copper to be heated evenly and melt quickly.

[0051] An anti-falling mesh plate 15 is fixedly connected between any two adjacent inclined rods 13. The anti-falling mesh plate 15 can prevent the electrolytic copper raw materials from directly falling into the bottom of the furnace body 1 when the electrolytic copper raw materials are manually or automatically delivered, thereby damaging the sensor at the bottom. The anti-falling mesh plate 15 is located close to the sensor, so melting can be achieved.

[0052] In addition, after no further feeding is needed, in order to prevent the copper liquid inside the furnace body 1 from being excessively oxidized, the furnace body 1 can be closed, and semicircular grooves 14 are provided on the surfaces of the first docking plate 3 and the second docking plate 4. When the first docking plate 3 and the second docking plate 4 are docked, the two semicircular grooves 14 are docked with the stirring rod 12, and oxygen can be isolated over a certain length. However, if the stirring rod 12 is removed, the semicircular grooves 14 will expose the copper liquid in the furnace body 1. Sealing plates 17 are movably connected to the surfaces of the first docking plate 3 and the second docking plate 4. The two sealing plates 17 can achieve the sealing of the semicircular grooves 14 under the action of the connecting spring 19.

[0053] However, during the use of the stirring rod 12, the sealing plate will squeeze the stirring rod 12, and when the stirring rod 12 rotates, the sealing plate 17 will cause wear to the stirring rod 12. Therefore, an anti-wear bearing 16 is connected to the surface of the stirring rod 12, and the sealing plate 17 is connected to the anti-wear bearing 16 to avoid direct connection with the stirring rod 12 and reduce wear.

[0054] When automatic feeding is performed, the docking hole plate 20 is installed on the packaging shell 2 by bolts, and the docking hole plate 20 is docked with the closing plate 10 to seal the top of the packaging shell 2. The electrolytic copper plate is sent into the cutting box 21, and the first cutting roller 22 cuts the material longitudinally to cut the electrolytic copper plate into strips. The strip-shaped electrolytic copper plate then passes through the limiting hole 24 to prevent deviation after cutting, and then passes through the second cutting roller 23 to cut the strip-shaped electrolytic copper plate into blocks. Then the block electrolytic copper plate falls into the interior of the packaging shell 2. The bottom of the docking hole plate 20 is fixedly connected with a guide shell, which can guide the block electrolytic copper plate to the top opening of the furnace body 1.

[0055] Before feeding, the first docking plate 3 and the second docking plate 4 are separated to facilitate the smooth entry of the block electrolytic copper plate, and an anti-falling mesh plate 15 can be set. After the feeding is completed, the first docking plate 3 and the second docking plate 4 are docked to prevent oxidation. In addition, in order to better prevent oxidation, an inert atmosphere can be formed inside the packaging shell 2, that is, inert gas is flushed into the packaging shell 2 through the air supply box 26. For the convenience of recycling, an exhauster 25 can be fixedly connected to the surface of the cutting box 21, and collected through an external collection device, so that the interior of the packaging shell 2 always maintains an inert atmosphere.

[0056] Through the above technical scheme, various feeding methods can be realized, and at the same time, the oxygen in the air can be prevented from oxidizing the copper liquid to cause excessive oxides, and stirring can be facilitated.
