Description

Technical Field

[0001] This invention relates to the field of metal casting, and more particularly to a vacuum continuous casting equipment capable of continuous operation. Background Technology

[0002] In the field of precision casting of metal wires (such as high-purity copper, special alloys, etc.), vacuum casting technology is a key process to ensure the high purity and excellent performance of products. Its core process is to place the metal billet in a crucible in a sealed chamber, heat and melt it in a low-oxygen or oxygen-free environment formed by vacuuming, and then draw the molten metal into wires under controlled conditions through a mold. However, in traditional processes, after each production batch is completed, the vacuum state of the sealed chamber must be released first, the chamber opened to clean the residual slag and impurities in the crucible, and new metal billets must be placed in. Then, the chamber must be resealed and a new round of vacuuming must be performed before the next casting can begin. In the above-mentioned preliminary work, the sealing of the chamber and the vacuuming require a long preparation time, which reduces the proportion of the actual metal billet melting and wire drawing production time in the overall operation cycle, making it difficult to effectively improve equipment utilization and production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a vacuum continuous casting equipment that can operate continuously. In a vacuum environment, the first feeding mechanism and the second feeding mechanism respectively complete the crucible feeding and filter crucible replacement, thereby improving production efficiency.

A first vacuum chamber is mounted on the workbench, containing a crucible. A first heating element is located outside the crucible. A tilting mechanism is provided on the workbench, driving the crucible to rotate via a central shaft. A mounting base is located near the crucible inside the first vacuum chamber, and a filter crucible is detachably connected to the mounting base. A filter screen is located inside the filter crucible. A first gate valve and a second gate valve are connected to the first vacuum chamber, respectively located near the crucible and the filter crucible. A first feeding mechanism and a second feeding mechanism are provided on the workbench, both rotatably connected to... The device includes a rotating base with a first tank body having a first opening. A gripper is slidably connected inside the first tank body. The rotating base is equipped with a first screw mechanism for driving the gripper to rise and fall. The first openings of the two first tank bodies are respectively located near a first slide valve and a second slide valve. A casting mechanism is provided on the expansion platform. The casting mechanism includes a second vacuum chamber and a cooling assembly. The second vacuum chamber contains a storage crucible communicating with a filter crucible. The cooling assembly has a cooling channel communicating with the storage crucible. A traction mechanism and a traction rod are provided on the expansion platform. The traction mechanism is located near the end of the cooling channel, and the traction rod passes through the cooling channel.

[0005] As a preferred embodiment, a tilting seat is rotatably connected inside the first vacuum chamber, the crucible is placed on the tilting seat and fixedly connected thereto, the central shaft passes through the first vacuum chamber and is fixedly connected to the tilting seat, and the height of the crucible is higher than the height of the filter crucible.

[0006] As a preferred embodiment, a first conduit passes through the central axis and is fixedly connected to the first heating component. A second conduit passes through the first conduit and is fixedly connected to the first heating component.

[0007] As a preferred embodiment, the flipping mechanism includes a flipping motor, the output shaft of which is fixedly connected to a first gear, and the outer side of the central shaft is fixedly connected to a second gear, with the first gear and the second gear engaging in a cooperative connection.

[0008] As a preferred embodiment, a slot is provided on the inner wall of the filter crucible, and a buckle extends from the gripper arm of the second feeding mechanism.

[0009] As a preferred embodiment, a second heating component is provided on the outside of the mounting base, and a receiving groove is provided on the mounting base, into which the filter crucible is placed.

[0010] As a preferred embodiment, both the first feeding mechanism and the second feeding mechanism include a feeding seat, a first lifting seat is slidably connected to the feeding seat, a first lifting component is provided on the feeding seat to drive the first lifting seat to rise and fall, a rotating seat is rotatably connected to the first lifting seat, and a driving component is provided on the feeding seat to drive the rotating seat to rotate.

[0011] As a preferred embodiment, the rotating seat of the first feeding mechanism is provided with multiple second tanks, each with a second opening. Each second tank is provided with a sliding and rotatable connecting rod, with a stirring head and a brush fixedly connected to two of the connecting rods respectively. The rotating seat of the first feeding mechanism is provided with multiple second screw devices, which drive the connecting rods to slide up and down on the second tanks. Each second screw device is provided with a rotary motor, which drives the connecting rods to rotate on the second tanks.

[0012] As a preferred embodiment, a sealing cover is fixedly connected to the bottom of the first vacuum chamber, the top of the second vacuum chamber touches the sealing cover, and the filter crucible communicates with the storage crucible through the sealing cover.

[0013] As a preferred embodiment, the cooling assembly includes a through pipe and a water storage tank. The through pipe is fixedly connected to the bottom of the second vacuum chamber. A second connecting piece is embedded at one end of the through pipe. The second connecting piece is inserted into the storage crucible. A cooling channel passes through the second connecting piece and the through pipe and is connected to the storage crucible. The water storage tank is fitted on the outside of the through pipe.

[0014] The beneficial effects of the continuously operating vacuum continuous casting equipment disclosed in this invention are: By closing the first and second gate valves and blocking the cooling channel with the traction rod, the first and second vacuum chambers are isolated from the outside world. The air inside both chambers is extracted by an external vacuuming mechanism, and different antioxidant gases are injected into them respectively, so that the crucible, filter crucible and storage crucible can all work in a vacuum environment filled with protective gas. First, the first heating component heats and melts the metal billet in the crucible. The protective gas in the first vacuum chamber prevents metal oxidation, thereby improving the quality of the molten metal. After melting, the flipping mechanism drives the central shaft to rotate the crucible, pouring the molten metal into the filter crucible. As the molten metal flows through the filter screen, slag impurities are filtered out, improving the purity of the molten metal. Subsequently, the filter crucible guides the filtered molten metal into the storage crucible. The specific protective gas in the second vacuum chamber ensures the casting quality of the molten metal during the heat preservation stage. When the molten metal flows through the cooling channel, it is rapidly cooled, crystallizes, and changes from a liquid to a solid state, forming a metal wire. After being pulled out of the cooling channel by the traction rod, it is continuously pulled out by the traction mechanism.

[0015] When a blank needs to be replenished, the first feeding mechanism drives the rotating seat to align the first opening of the first tank with the first slide valve. After the first slide valve opens, its first screw device drives the gripper to descend, placing the blank into the crucible and then resetting it. Subsequently, the first slide valve closes. This process can be completed without opening the first vacuum chamber.

[0016] When the filter crucible needs to be replaced, the second feeding mechanism drives the rotating seat to align the first tank with the second slide gate valve. After the second slide gate valve opens, its first screw device drives the gripper to descend, pick up the old crucible and return it to the tank, and the second slide gate valve closes. Subsequently, the rotating seat moves the old crucible to the designated position and retrieves the new crucible. After aligning again and opening the second slide gate valve, the new crucible is placed on the mounting base. The slag impurities are cleaned by replacing the filter crucible, and this process can be completed without opening the first vacuum chamber.

[0017] Through the coordinated operation of the first and second feeding mechanisms with the first and second slide gate valves, respectively, the system can complete the feeding of metal billets and the replacement of filter crucibles without stopping the machine or damaging the vacuum of the first vacuum chamber, ensuring that the metal billets are always smelted in an oxygen-free environment, thereby significantly improving production efficiency and smelting quality. Furthermore, the design of the dual vacuum chambers allows the molten metal to use two different antioxidant gases under two different working conditions, further improving the quality of smelting and casting.

The connection between the inlet pipe and the first interlayer is located on one side of the first vacuum chamber 2, and the connection between the outlet pipe and the first interlayer is located on the other side of the first vacuum chamber 2. This allows the cooling water injected into the first interlayer by the external water circulation mechanism through the inlet pipe to flow along one side of the first vacuum chamber 2 to the other side, and then return to the external water circulation mechanism through the outlet pipe, thereby cooling the chamber of the first vacuum chamber 2. Furthermore, the first vacuum chamber 2 is connected to a first connecting channel 22 and a second connecting channel 23. The end of the first connecting channel 22 is connected to a first gate valve 221, and the end of the second connecting channel 23 is connected to a second gate valve 231.

[0034] A flipping seat 24 is rotatably connected inside the first vacuum chamber 2. One end of the flipping seat 24 is fixedly connected to a rotating shaft 241, which is rotatably connected to the inner wall of the first vacuum chamber 2. An installation cavity is provided on the flipping seat 24 for placing a crucible 242. Furthermore, a bushing is provided inside the first vacuum chamber 2, and the bushing extends out of the first vacuum chamber 2. In this embodiment, it is preferred that the gap between the bushing and the first vacuum chamber 2 is sealed by a first sealing ring. A central shaft 25 is provided on the first vacuum chamber 2.

Furthermore, a first heating assembly is provided on the outside of the crucible 242. The first heating assembly includes a first heating coil 28, the middle part of which is coiled around the outside of the crucible 242. Both ends of the first heating coil 28 are fixedly connected to connecting pipes 281. In this embodiment, the connection between the first heating coil 28 and the connecting pipes 281 is preferably filled with sealant, which is used to seal the connection between the first heating coil 28 and the connecting pipes 281. The two connecting pipes 281 are respectively connected to one end of the second conductor 27 and one end of the connecting pipe. An external positive wire passes through a wire hole, a first wire tube 26, a connecting tube, and a section of a connecting tube 281 in sequence and is electrically connected to one end of a first heating coil 28. An external negative wire passes through a second wire tube 27 and another section of a connecting tube 281 in sequence and is electrically connected to the other end of a first heating coil 28. This allows an external power source to energize the first heating coil 28 via the external positive and external negative wires, causing the first heating coil 28 to generate heat to heat the crucible 242 and melt the metal billet 562 placed in the crucible 242, turning it into molten metal.

When the gripper 561 of the first feeding mechanism 5 grips the metal billet 562, the teeth contact the metal billet 562, increasing the friction between the gripper arm of the gripper 561 and the metal billet 562. A buckle extends from the gripper arm of the second feeding mechanism 6 gripper 561. When the gripper 561 of the second feeding mechanism 6 grips the filter crucible 44, the buckle engages in the slot 441, increasing the firmness of the gripper 561 of the second feeding mechanism 6 in gripping the filter crucible 44.

This allows the cooling water injected into the second interlayer by the external water circulation mechanism through the inlet pipe to flow along one side of the second vacuum chamber 9 to the other side, and then return to the external water circulation mechanism through the outlet pipe, thereby cooling the chamber of the second vacuum chamber 9. Furthermore, the top of the second vacuum chamber 9 is provided with an inspection port, and a seventh sealing ring is fixedly connected to the inspection port of the second vacuum chamber 9; a sealing cover 29 is fixedly connected to the bottom of the first vacuum chamber 2, and an eighth sealing ring is fixedly connected to the sealing cover 29. The eighth sealing ring touches the bottom of the first vacuum chamber 2 and is used to seal the gap between the first vacuum chamber 2 and the sealing cover 29. The discharge channel 411 passes through the sealing cover 29 and is located inside the eighth sealing cover. Furthermore, the second vacuum chamber 9 is equipped with a storage crucible 93, which has a second discharge port. A connecting bracket is installed on the storage crucible 93, and a first docking member 94 is fixedly connected to the connecting bracket. A material injection channel 941 passes through the first docking member 94 and communicates with the storage crucible 93. Two conductive rods 95 are fixedly connected to the connecting bracket. In this embodiment, the conductive rods 95 are preferably made of graphite material, and the two conductive rods 95 are configured with one long and one short, with the longer one being the longer one. The conductive rod 95 extends to the bottom of the storage crucible 93, and the shorter conductive rod 95 extends to the middle of the storage crucible 93. When the molten metal in the storage crucible 93 is above the shorter conductive rod 95, the two conductive rods 95 form a conductive path. When the molten metal in the storage crucible 93 is below the shorter conductive rod 95, the conductive path between the two conductive rods 95 is broken, thereby determining the capacity of the molten metal in the storage crucible 93. In this embodiment, the current conducted by the conductive rod 95 is preferably a low-voltage current. Furthermore, a third heating coil 931 is provided on the outside of the storage crucible 93. The middle part of the third heating coil 931 is coiled around the outside of the storage crucible 93. An external power supply energizes the third heating coil 931, causing it to generate heat to keep the storage crucible 93 warm. A temperature monitoring device 96 is fixedly connected to the outside of the second vacuum box 9. The temperature monitoring device 96 penetrates into the second vacuum box 9 and contacts the storage crucible 93. The temperature monitoring device 96 is used to monitor the temperature of the storage crucible 93 in real time. When the temperature of the storage crucible 93 is lower than the preset temperature, the temperature of the heat generated by the third heating coil 931 is increased to maintain the temperature of the storage crucible 93.

[0049] The cooling assembly 83 includes a through pipe and a water storage tank 84; one end of the through pipe is fixedly connected to the bottom of the second vacuum box 9, and a ninth sealing ring is fixedly connected to one end of the through pipe. The ninth sealing ring touches the bottom of the second vacuum box 9 and is used to seal the gap between the through pipe and the second vacuum box 9; a second docking member 832 is embedded in one end of the through pipe, and the second docking member 832 passes through the second vacuum box 9 and enters the storage crucible 93. Furthermore, the casting mechanism 8 is equipped with a cooling channel 834, which passes through the second connecting piece 832 and the through pipe. One end of the cooling channel 834 is connected to the second discharge port of the storage crucible 93. Furthermore, a water storage tank 84 is fitted onto the outside of the through pipe. The water storage tank 84 is provided with a water inlet channel 841. One end of the water inlet channel 841 enters the water storage tank 84 from one end and extends to the other end of the water storage tank 84. The other end of the water storage tank 84 is connected to a drain channel 842. The water inlet pipe of the external water circulation mechanism is connected to the other end of the water inlet channel 841, and the water return pipe of the external water circulation mechanism is connected to the drain channel 842. When the external water circulation mechanism injects cooling water into the water storage tank 84 through the water inlet channel 841, the cooling water flows from one end of the water storage tank 84 to the other end, and returns to the external water circulation mechanism through the drain channel 842, thus improving the cooling effect of the through pipe.

[0050] The travel cylinder 813 pulls the travel slide 812 to slide on the guide rail 811 and approach the lower part of the first vacuum box 2, so that the inspection port of the second vacuum box 9 is aligned with the sealing cover 29; the second lifting cylinder 821 pushes the second vacuum box 9 to rise, so that the inspection port of the second vacuum box 9 is pressed against the sealing cover 29, and the seventh sealing ring seals the gap between the second vacuum box 9 and the sealing cover 29. The first docking part 94 docks with the mounting base 4, so that the injection channel 941 is connected with the discharge channel 411, thereby connecting the storage crucible 93 with the filter crucible 44. The molten metal in the filter crucible 44 can enter the storage crucible 93 in sequence through the discharge port, the discharge channel 411 and the injection channel 941. The molten metal in the storage crucible 93 enters the second discharge port under the action of gravity, and is guided to the other end through one end of the cooling channel 834. During this process, the cooling water rapidly cools the pipe, so that the molten metal in the cooling channel 834 is cooled and solidified to form a metal wire that is discharged from the other end of the cooling channel 834.

[0051] During equipment maintenance, the second lifting cylinder 821 pulls the second vacuum box 9 down, so that the second vacuum box 9 is away from the sealing cover 29. The traveling cylinder 813 pushes the traveling slide 812 to slide on the guide rail 811 away from the bottom of the first vacuum box 2, so that the operator can replace the parts inside the second vacuum box 9 through the inspection port.

[0052] Please refer to Figure 1 and Figures 11-13 .

[0053] The expansion platform 7 has a material inlet 71 located below the other end of the cooling channel 834. The expansion platform 7 is equipped with a traction mechanism 72 located below the material inlet 71. The traction mechanism 72 includes a cabinet, a traction motor, and a traction rod. Two connecting seats are fixedly connected to the rack, arranged side by side. A drive wheel is rotatably connected to the connecting seats, and a drive shaft extends from one end of the drive wheel. The drive shaft passes into the rack, and the part of the drive shaft inside the rack is fixedly connected to a first pulley. Two spring seats are fixedly connected to the rack, arranged side by side. The connecting seats and spring seats are arranged opposite each other. A spring rod is slidably connected to the spring seat, and a contact wheel is rotatably connected to the spring rod. The spring seat pushes the contact wheel toward the drive wheel through the spring rod. A threaded hole is opened at the top of the traction rod. The traction motor is placed inside the cabinet. A second pulley and a third pulley are fixedly connected to the output shaft of the traction motor. The second pulley and the third pulley are coaxial. A first transmission belt is fitted on one of the first pulleys and the second pulley, and a second transmission belt is fitted on the other first pulley and the third pulley. The traction rod is placed between the drive wheel and the contact wheel. The top of the traction rod is pushed into the cooling channel 834, blocking the cooling channel 834. After the molten metal enters the cooling channel 834, it flows into the threaded hole and solidifies in the cooling channel, allowing the traction rod to pull the solidified metal wire. The spring seat pushes the contact wheel to contact the traction rod, pressing it against the drive wheel and increasing the friction between the traction rod and the drive wheel. The output shaft of the traction motor drives two drive shafts to rotate via the first and second transmission belts, which in turn drive two drive wheels to rotate synchronously. The metal wire is pulled out from the cooling channel 834 by the traction rod. After the metal wire is removed from the metal wire by rotating the traction rod, the metal wire is placed between the drive wheel and the contact wheel. The spring seat pushes the contact wheel to touch the metal wire, pressing it against the drive wheel. The drive wheel pulls the metal wire continuously out from the cooling channel 834.

[0054] The cabinet has multiple adjusting blocks and multiple screw seats that slide together. Screws are rotatably connected to the adjusting blocks, and the screws are connected to the screw seats. Guide wheels are rotatably connected to the adjusting blocks. By rotating the screw and sliding it on the screw seat, the position of the adjusting block on the cabinet is changed, so that multiple guide wheels are located on both sides of the metal wire. When the metal wire approaches the guide wheel under the traction of the drive wheel, by changing the position of the adjusting block on the cabinet, the guide wheel can push the metal wire to change the direction of movement, so that the metal wire moves towards the external winding mechanism, allowing the external winding mechanism to better wind up the processed metal wire.

[0055] Please refer to Figures 1-13 .

[0056] When the device is running: The first slide valve 221 and the second slide valve 231 are closed to isolate the first vacuum chamber 2 from the outside world. The traveling cylinder 813 pulls the traveling slide 812 to slide along the guide rail 811, so that the second vacuum chamber 9 is located below the first vacuum chamber 2. At the same time, the second lifting cylinder 821 pushes the second vacuum chamber 9 to rise, so that the inspection port of the second vacuum chamber 9 is pressed against the sealing cover 29, and the traction rod is pushed to block the cooling channel, thereby isolating the second vacuum chamber 9 from the outside world. At this time, the air in the first vacuum chamber 2 and the second vacuum chamber 9 is extracted by the external vacuuming mechanism, and different anti-oxidation gases are injected into the first vacuum chamber 2 and the second vacuum chamber 9, so that the crucible 242, the filter crucible 44 and the storage crucible 93 all work in a vacuum environment filled with anti-oxidation gas. The anti-oxidation gas in the first vacuum chamber can prevent the metal billet from undergoing oxidation reaction during melting, thereby improving the quality of the molten metal. The specific anti-oxidation gas in the second vacuum chamber can ensure the casting quality of the molten metal during the heat preservation stage. The first heating coil 28 is energized, which generates heat and heats the crucible 242, thereby melting the metal billet 562 placed in the crucible 242 to form molten metal. After melting is completed, the output shaft of the flipping motor 31 drives the second gear 252 to rotate through the first gear 311, which in turn drives the flipping seat 24 and the crucible 242 to rotate through the central shaft 25, so that the molten metal in the crucible 242 is guided into the filter crucible 44 along the feed inlet. The molten metal must pass through the filter screen 442 before flowing into the first outlet. The filter screen 442, made of graphite, can filter out slag impurities mixed in with the molten metal. The second heating coil 43 is energized to generate heat and heat the filter crucible 44 to keep the molten metal inside the filter crucible 44 warm. The filtered molten metal in the filter crucible 44 enters the storage crucible 93 in sequence through the outlet, the discharge channel 411, and the injection channel 941. The third heating coil 931 is energized to generate heat and heat the storage crucible 93 to keep the molten metal inside the storage crucible 93 warm. Under the action of gravity, the molten metal in the storage crucible 93 flows into the cooling channel 834 through the second outlet. When the molten metal flows through the cooling channel, the cooling water rapidly cools the pipe, causing the molten metal to crystallize and change from a liquid to a solid state, forming a metal wire, which is finally discharged from the other end of the cooling channel 834 under the pull of the traction rod. After solidification, the metal wire is led out from the cooling channel 834 and passes through the feed port 71. After the traction rod is removed from the metal wire, the metal wire is placed between the drive wheel and the contact wheel. The drive wheel and the contact wheel together clamp the metal wire, and the metal wire is moved by the rotation of the drive wheel, thereby continuously pulling the metal wire out of the cooling channel 834. The two conductive rods 95 in the storage crucible 93 monitor the remaining amount of molten metal in real time and adjust the speed of the drive wheel accordingly to control the traction speed of the metal wire and avoid the molten metal content in the storage crucible 93 being too low. After the metal wire changes its direction of movement through multiple guide wheels, it is conveyed towards the external winding mechanism, which winds up the processed metal wire.

[0057] When crucible 242 needs to be loaded: After all the molten metal in the crucible 242 is poured into the filter crucible 44, the flipping motor 31 drives the flipping seat 24 and the crucible 242 to reset via the central shaft 25, so that the crucible 242 is located directly below the first gate valve 221. The drive motor of the first feeding mechanism 5 drives the rotating seat to rotate, aligning the first opening of the first tank 56 with the first slide valve 221; the first lifting cylinder 523 of the first feeding mechanism 5 pulls the first lifting seat 521 down, causing the sealing sleeve 63 of the first tank 56 to press against the first slide valve 221, thus connecting the first tank 56 with the first slide valve 221. Then, the first slide valve 221 opens, connecting the first tank 56 with the first vacuum chamber 2; next, the first lead screw device 57 of the first feeding mechanism 5 drives the gripper 561 to descend into the first vacuum chamber 2 through the connecting pipe 563, placing the metal billet 562 into the crucible 242; then, the gripper 561 is driven to reset, the first slide valve 221 closes, cutting off the connection between the first tank 56 and the first vacuum chamber 2, completing the feeding of the metal billet 562; The first lifting cylinder 523 of the first feeding mechanism 5 pushes the first lifting seat 521 to rise, so that the first tank 56 is away from the first slide valve 221; then, the drive motor of the first feeding mechanism 5 drives the first tank 56 to rotate above the material area so that the gripper 561 can pick up the new metal billet 562.

[0058] When crucible 242 needs to be stirred: After the metal billet 562 is loaded, the first heating coil 28 is energized to generate heat and heat the crucible 242 to melt the metal billet 562 therein. The drive motor of the first feeding mechanism 5 drives the rotating seat to rotate, moving the second tank 58 containing the stirring head 582 above the first slide valve 221, aligning the second opening of the second tank 58 with the first slide valve 221; the first lifting cylinder 523 pulls the first lifting seat 521 down, causing the sealing sleeve 63 of the second tank 58 to press against the first slide valve 221, thus connecting the second tank 58 with the first slide valve 221. Then the first slide valve 221 opens, connecting the second tank 58 with the first vacuum box 2; the second lead screw device 59 drives the stirring head 582 down into the crucible 242 through the connecting rod 581, and the output shaft of the rotary motor 591 drives the stirring head 582 to rotate through the connecting rod 581, thereby stirring the molten metal in the crucible 242; After stirring is completed, the second lead screw device 59 drives the stirring head 582 to reset, and then the first gate valve 221 closes, cutting off the connection between the second tank 58 and the first vacuum box 2.

[0059] When crucible 242 needs to be cleaned of slag impurities (first cleaning method): After the molten metal is poured into the filter crucible 44 through the crucible 242, the flipping motor 31 drives the flipping seat 24 and the crucible 242 to reset through the central shaft 25, so that the crucible 242 is located directly below the first gate valve 221. The drive motor of the first feeding mechanism 5 drives the rotating seat to rotate, so that the second tank 58, which contains the brush 583 and the waste tray 584, moves to above the first slide gate valve 221, aligning the second opening of the second tank 58 with the first slide gate valve 221. The first lifting cylinder 523 pulls the first lifting seat 521 down, so that the sealing sleeve 63 of the second tank 58 presses against the first slide gate valve 221, realizing the docking of the second tank 58 with the first slide gate valve 221. Then the first slide gate valve 221 opens, so that the second tank 58 is connected to the first vacuum box 2. The second screw device 59 drives the brush 583 and the waste tray 584 to descend into the crucible 242 through the connecting rod 581. The output shaft of the rotary motor 591 drives the brush 583 to rotate through the connecting rod 581, thereby scraping off the slag impurities attached to the inner wall of the crucible 242. The cleaned slag impurities fall into the waste tray 584 for collection. After cleaning is completed, the second lead screw device 59 drives the brush 583 and waste tray 584 to reset, and then the first slide valve 221 closes, cutting off the connection between the second tank 58 and the first vacuum box 2.

[0060] When filter crucible 44 needs to be replaced (second cleaning method): This method is based on the following situation: when the crucible 242 pours the molten metal into the filter crucible 44, most of the slag impurities enter the filter crucible 44, causing slag impurities to accumulate on the filter screen 442 of the filter crucible 44 after filtering a certain amount of molten metal. After the molten metal in the filter crucible 44 has been filtered, the drive motor of the second feeding mechanism 6 drives the rotating seat to rotate, aligning the first opening of the first tank 56 with the second slide valve 231. The first lifting cylinder 523 of the second feeding mechanism 6 pulls the first lifting seat 521 down, causing the sealing sleeve 63 of the first tank 56 to press against the second slide valve 231, thus connecting the first tank 56 with the second slide valve 231. The second slide valve 231 opens, connecting the first tank 56 with the first vacuum chamber 2. The first screw device 57 of the second feeding mechanism 6 drives the gripper 561 to descend into the first vacuum chamber 2 through the connecting pipe 563. The gripper 561 drives the gripping arm to open, causing the buckle to engage in the slot 441 of the filter crucible 44, thereby clamping the filter crucible 44. The first screw device 57 drives the gripper 561 to reset, and the second slide valve 231 closes, cutting off the connection between the first tank 56 and the first vacuum chamber 2. The first lifting cylinder 523 of the second feeding mechanism 6 pushes the first lifting seat 521 to rise, so that the first tank 56 is away from the second slide valve 231. Then the drive motor drives the first tank 56 to rotate above the material rack. The gripper 561 places the old filter crucible 44 on the material rack and clamps the new filter crucible 44. Next, the drive motor of the second feeding mechanism 6 drives the rotating seat to rotate again, so that the first opening of the first tank 56 is aligned with the second slide valve 231. The first lifting cylinder 523 of the second feeding mechanism 6 pulls the first lifting seat 521 down, so that the sealing sleeve 63 of the first tank 56 presses against the second slide valve 231, realizing the docking of the first tank 56 and the second slide valve 231. Then the second slide valve 231 opens, so that the first tank 56 is connected to the first vacuum box 2. The first screw device 57 of the second feeding mechanism 6 drives the gripper 561 to descend through the connecting pipe 563, and places the new filter crucible 44 on the mounting base 4. After the replacement is completed, the first lead screw device 57 of the second feeding mechanism 6 drives the gripper 561 to reset, the second slide valve 231 closes, and the connection between the first tank 56 and the first vacuum box 2 is cut off.

[0061] Filtering crucible 44 improves filtration efficiency when filtering molten metal. To improve filtration efficiency, after the crucible 242 pours all the molten metal into the filter crucible 44, the drive motor of the second feeding mechanism 6 drives the rotating seat to rotate, aligning the first opening of the third tank 61 with the second slide valve 231. The first lifting cylinder 523 pulls the first lifting seat 521 down, causing the sealing sleeve 63 of the third tank 61 to press against the second slide valve 231, thus connecting the third tank 61 with the second slide valve 231. Subsequently, the second slide valve 231 opens, connecting the third tank 61 with the first vacuum chamber 2. Then, the third screw device 62 drives the piston 612 down into the first vacuum chamber 2 through the connector 611, causing the piston 612 to touch the edge of the filter crucible 44. The third screw device 62 continuously pushes the piston 612 down, applying pressure to the molten metal and causing it to pass through the filter screen 442 more quickly. After filtration is completed, the third lead screw device 62 drives the piston 612 to reset, and then the second gate valve 231 closes, cutting off the connection between the third tank 61 and the first vacuum box 2.

[0062] This invention provides a vacuum continuous casting equipment that can operate continuously. By closing the first and second slide gate valves and blocking the cooling channel with the traction rod, the first and second vacuum chambers are isolated from the outside world. An external vacuum pumping mechanism is used to extract the air from both chambers and inject different antioxidant gases into them, so that the crucible, filter crucible and storage crucible all work in a vacuum environment filled with protective gas. First, the first heating component heats and melts the metal billet in the crucible. The protective gas in the first vacuum chamber prevents metal oxidation, thereby improving the quality of the molten metal. After melting, the flipping mechanism drives the central shaft to rotate the crucible, pouring the molten metal into the filter crucible. As the molten metal flows through the filter screen, slag impurities are filtered out, improving the purity of the molten metal. Subsequently, the filter crucible guides the filtered molten metal into the storage crucible. The specific protective gas in the second vacuum chamber ensures the casting quality of the molten metal during the heat preservation stage. When the molten metal flows through the cooling channel, it is rapidly cooled, crystallizes, and changes from a liquid to a solid state, forming a metal wire. After being pulled out of the cooling channel by the traction rod, it is continuously pulled out by the traction mechanism.

[0063] When a blank needs to be replenished, the first feeding mechanism drives the rotating seat to align the first opening of the first tank with the first slide valve. After the first slide valve opens, its first screw device drives the gripper to descend, placing the blank into the crucible and then resetting it. Subsequently, the first slide valve closes. This process can be completed without opening the first vacuum chamber.

[0064] When the filter crucible needs to be replaced, the second feeding mechanism drives the rotating seat to align the first tank with the second slide gate valve. After the second slide gate valve opens, its first screw device drives the gripper to descend, pick up the old crucible and return it to the tank, and the second slide gate valve closes. Subsequently, the rotating seat moves the old crucible to the designated position and retrieves the new crucible. After aligning again and opening the second slide gate valve, the new crucible is placed on the mounting base. The slag impurities are cleaned by replacing the filter crucible, and this process can be completed without opening the first vacuum chamber.

[0065] Through the coordinated operation of the first and second feeding mechanisms with the first and second slide gate valves, respectively, the system can complete the feeding of metal billets and the replacement of filter crucibles without stopping the machine or damaging the vacuum of the first vacuum chamber, ensuring that the metal billets are always smelted in an oxygen-free environment, thereby significantly improving production efficiency and smelting quality. Furthermore, the design of the dual vacuum chambers allows the molten metal to use two different antioxidant gases under two different working conditions, further improving the quality of smelting and casting.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
