[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0043] Example 1:

[0044] See Figures 1 to 6 An alloy vacuum induction melting and rapid solidification equipment includes a support part 1 and a smelting chamber 2 fixedly installed on the upper end of the support part 1, a smelting component 3 is provided in the middle of the inner side of the smelting chamber 2, a slag component 4 is provided on the side of the smelting component 3, and a cooling component 5 is provided below the side of the slag component 4 away from the smelting component 3, and the cooling component 5 is slidably fitted with the inner wall of the smelting chamber 2.

[0045] A feed pipe 21 is installed in the middle of the upper end of the smelting chamber 2, a vacuum pipe 22 is provided on one side of the feed pipe 21, a vacuum release valve 23 is installed on the side of the feed pipe 21 away from the vacuum pipe 22, and a chamber door 24 is provided on the side wall of the end of the smelting chamber 2.

[0046] The smelting assembly 3 includes an electrode assembly 31, which is rotatably mounted in the middle of the side wall of the smelting chamber 2. One end of the electrode assembly 31 extends to the outside of the smelting chamber 2 and is connected to the power supply through a wire. The other end of the electrode assembly 31 extends to the inside of the smelting chamber 2 and is connected to an induction coil 32. A smelting crucible 33 is provided inside the induction coil 32, and the outer wall of the smelting crucible 33 and the induction coil 32 are in contact. A connecting frame 34 is fixedly mounted on the side wall of the smelting crucible 33 away from the electrode assembly 31. One end of the connecting frame 34 away from the smelting crucible 33 extends to the outside of the smelting chamber 2 and is connected to the output shaft of the drive motor 35. The drive motor 35 is fixedly mounted on the side wall of the smelting chamber 2 through a motor base.

[0047] The filter residue assembly 4 includes an arc groove 41. The arc groove 41 is symmetrically opened on the inner wall of the smelting chamber 2 and located on one side of the smelting assembly 3. A support plate 42 is slidably installed inside the arc groove 41 through an extrusion spring 43. The proximal end of the support plate 42 is detachably connected to a ceramic filter screen 44. The smelting crucible 33 and the ceramic filter screen 44 are both made of high-temperature resistant graphite material.

[0048] A guide plate 441 is fixedly installed on the lower edge of the side wall of the ceramic filter 44 away from the smelting component 3, and an arc-shaped anti-overflow strip 442 is fixedly installed on the outer edge of the lower half of the side wall of the ceramic filter 44 close to the smelting component 3.

[0049] During the specific operation, the feed tube 21 is first opened manually, and then two or more metal materials are added into the smelting crucible 33 from the feed tube 21. Then, the end cover at the upper end of the feed tube 21 is closed, and the vacuum tube 22 is connected to the external exhaust device. The inside of the smelting chamber 2 is evacuated by the external exhaust device, and the external power supply is started. The electrode assembly 31 is energized by the external power supply, thereby driving the induction coil 32 to heat and melt the metal material inside the smelting crucible 33. During the heating process, the inside of the smelting chamber 2 can be observed manually through the observation window provided on the chamber door 24. When the metal material inside the smelting crucible 33 is melted into molten metal, the drive motor 35 is started, and the drive motor 35 drives the connected The frame 34 and the smelting crucible 33 are rotated 90 degrees toward the chamber door 24, thereby pouring the molten metal inside the smelting crucible 33 into the cooling assembly 5. During this process, the smelting crucible 33 will continuously squeeze the ceramic filter screen 44 and drive the support plate 42 to move in the arc groove 41, thereby driving the extrusion spring 43 to compress. Subsequently, the molten metal inside the smelting crucible 33 will be filtered by the ceramic filter screen 44 and then flow downward through the guide plate 441 into the cooling assembly 5. The ceramic filter screen 44 can filter the slag in the molten metal into the smelting crucible 33, and the arc-shaped anti-overflow strip 442 can prevent the molten metal from overflowing and falling during the pouring process, causing waste. After the pouring is completed, the connecting frame 34 and the smelting crucible 33 are reset by the driving motor 35.

[0050] See Figures 1 to 4 as well as Figures 7 to 11 The cooling assembly 5 includes a mold barrel 51. The mold barrel 51 is provided below the side of the slag assembly 4 away from the smelting assembly 3. The lower end of the mold barrel 51 is in sliding contact with the bottom of the smelting chamber 2 through a guide unit 52. The upper end of the side wall of the mold barrel 51 is symmetrically installed with a lining plate 53. The end of the lining plate 53 away from the mold barrel 51 is rotatably installed with a pulley 54. The pulley 54 and the side wall of the smelting chamber 2 are slidably matched. A cooling unit 55 is provided on the outside of the mold barrel 51 near the upper end. The upper end of the side of the cooling unit 55 is opposite to the lower end of one of the lining plates 53. The lower end of the cooling unit 55 passes through the smelting chamber 2 and extends to the outside of the smelting chamber 2. A side skirt 56 is fixedly installed on the lower end of the outer wall of the mold barrel 51. A receiving groove is formed between the side skirt 56 and the side wall of the mold barrel 51.

[0051] The guide unit 52 includes an arc-shaped limit bar 521, which is symmetrically installed on the inner wall of the smelting chamber 2 below the mold barrel 51. A slideway is formed between the two arc-shaped limit bars 521. The mold barrel 51 is installed with a plurality of rollers 522 through a roller frame plate 523. The lower ends of the rollers 522 are located on the inner side of the slideway and are in sliding contact with the bottom of the smelting chamber 2.

[0052] The cooling unit 55 includes a high-pressure water pipe 551, wherein the high-pressure water pipe 551 is provided through the side wall of the smelting chamber 2 below one of the liner plates 53. A retaining ring 553 is fixedly installed on the inner side of the high-pressure water pipe 551 near the upper end, and a top cap 552 is installed on the upper end of the retaining ring 553. A transverse support pipe 554 is installed on the upper end of the side wall of the high-pressure water pipe 551. The end of the transverse support pipe 554 away from the high-pressure water pipe 551 is connected to an annular water reservoir 555. Water spray valves are evenly installed on the inner wall of the annular water reservoir 555 along its circumference.

[0053] The top cap 552 is a hollow structure with a spherical upper end, and an overflow hole 5521 is formed on the side wall of the top cap 552 near the lower end.

[0054] During specific operation, after the molten metal enters the mold barrel 51, high-pressure water flow is intermittently introduced into the high-pressure water pipe 551 through an external water supply device. The pressure of the high-pressure water flow will drive the top cap 552 to be pushed upward and drive the lining plate 53 to tilt. Under the action of the pulley 54 and the guide unit 52, the mold barrel 51 can swing back and forth, thereby driving the molten metal inside it to swing, thereby increasing the contact area between the molten metal and the inner wall of the mold barrel 51. When the overflow hole 5521 moves to the same height as the horizontal support pipe 554, the high-pressure water flow will pass through the horizontal support pipe 554 into the annular water reservoir 555, and then be sprayed onto the outer wall of the mold barrel 51 through the water spray valve, and finally formed between the side skirt 56 and the side wall of the mold barrel 51. The water vapor is collected by the receiving groove, thereby quickly cooling the molten metal inside the mold barrel 51. During the cooling process, the water flow sprayed by the water spray valve will quickly vaporize after contacting the outer wall of the mold barrel 51. The vaporized water vapor can increase the pressure inside the smelting chamber 2. When the pressure reaches the preset value, the vacuum release valve 23 will open. At this time, the water vapor inside the smelting chamber 2 will be quickly discharged through the vacuum release valve 23. During the discharge process, the water vapor can take away the heat of the molten metal and the waste gas generated by the metal material during the melting process, thereby improving the quality of the alloy ingot. After the molten metal inside the mold barrel 51 is cooled into an alloy ingot, the cavity door 24 is manually opened, and the alloy ingot is taken out for subsequent operations through the existing lifting equipment.

[0055] Example 2:

[0056] The technical solution is basically the same as that of embodiment 1, see Figure 2 、 Figure 4 as well as Figure 12 and Figure 13 The difference is that a slag filter cylinder 6 is installed below the side of the smelting assembly 3 away from the slag filter assembly 4, and the lower end of the slag filter cylinder 6 is fixedly connected to the bottom of the smelting chamber 2. A slag scraping assembly 7 is provided above the slag filter cylinder 6 at a position corresponding to the smelting assembly 3, and the slag scraping assembly 7 is installed on the side wall of the smelting chamber 2.

[0057] The slag removal assembly 7 includes an electric push rod 71. An electric push rod 71 is provided on the side wall of the smelting chamber 2 away from the chamber door 24. The electric push rod 71 slides with the side wall of the smelting chamber 2 away from the chamber door 24 through the push rod base and the middle part of the lower end of the push rod base is fixedly connected to a shift rod 77. The telescopic end of the electric push rod 71 extends into the interior of the smelting chamber 2 and is fixedly connected to an electromagnet block 72. A transverse shaft 73 is fixedly connected to the middle part of the side wall of the electromagnet block 72. An insulating cylinder 74 is provided on the outside of the transverse shaft 73. The end of the transverse shaft 73 away from the electromagnet block 72 extends to the inside of the insulating cylinder 74 and is evenly hinged with a transition rod 75 along its circumference. The insulating cylinder 74 opens toward the smelting assembly 3 and its end side wall close to the smelting assembly 3 is evenly hinged with a slag removal tooth 76 along its circumference through a torsion spring. The middle part of the side wall of the slag removal tooth 76 is hinged with the end of the transition rod 75 away from the transverse shaft 73.

[0058] In this embodiment, the heat insulating tube 74 has magnetic attraction.

[0059] In specific operation, after the melting crucible 33 is reset, the connecting frame 34 and the melting crucible 33 are driven by the driving motor 35 to rotate 90 degrees in the opposite direction, and then the electric push rod 71 is started, and the electric push rod 71 drives the electromagnet block 72, the horizontal shaft 73, the insulation cylinder 74, the transition rod 75 and the slag scraping teeth 76 to move into the melting crucible 33. When the slag scraping teeth 76 contact the side wall of the melting crucible 33, the electromagnet block 72 is energized, and then the electric push rod 71 continues to push, and the electromagnet block 72 will move toward the insulation cylinder 74, and finally the electromagnet The iron block 72 will be attracted to the end of the insulation tube 74, and the slag scraping teeth 76 will move to a state of contact with the inner wall of the melting crucible 33. Then, the electric push rod 71 will drive the electromagnet block 72, the horizontal shaft 73, the insulation tube 74, the transition rod 75 and the slag scraping teeth 76 to move away from the melting crucible 33 as a whole, so that the slag inside the melting crucible 33 is scraped into the slag filter tube 6 by the slag scraping teeth 76. During the slag scraping process, the slag scraping assembly 7 can be driven to rotate as a whole by manually controlling the lever 77, thereby improving the slag removal efficiency.

[0060] The working principle of the present invention when in use:

[0061] One: First, manually open the discharge pipe 21, then add two or more metal materials into the melting crucible 33 from the discharge pipe 21, then close the end cover at the upper end of the discharge pipe 21, connect the vacuum tube 22 to the external exhaust device, evacuate the interior of the melting chamber 2 through the external exhaust device, start the external power supply, and energize the electrode assembly 31 through the external power supply, thereby driving the induction coil 32 to heat and melt the metal material inside the melting crucible 33. During the heating process, the internal situation of the melting chamber 2 can be observed manually through the observation window provided on the chamber door 24.

[0062] Second: After the metal material inside the smelting crucible 33 is melted into molten metal, the drive motor 35 is started, and the drive motor 35 drives the connecting frame 34 and the smelting crucible 33 to rotate 90 degrees toward the chamber door 24, so that the molten metal inside the smelting crucible 33 is poured into the mold barrel 51. During this process, the smelting crucible 33 will continuously squeeze the ceramic filter screen 44 and drive the support plate 42 to move in the arc groove 41, thereby driving the extrusion spring 43 to compress. Subsequently, the molten metal inside the smelting crucible 33 will be filtered by the ceramic filter screen 44 and then flow downward through the guide plate 441 into the cooling assembly 5. The ceramic filter screen 44 can filter the slag in the molten metal in the smelting crucible 33, and the arc-shaped anti-overflow strip 442 can prevent the molten metal from overflowing and falling during the pouring process, causing waste. After the pouring is completed, the drive motor 35 drives the connecting frame 34 and the smelting crucible 33 to reset.

[0063] 3: After the molten metal enters the mold barrel 51, high-pressure water is intermittently introduced into the high-pressure water pipe 551 through an external water supply device. The pressure of the high-pressure water will drive the top cap 552 to push upward and drive the liner 53 to tilt. Under the action of the pulley 54 and the guide unit 52, the mold barrel 51 can rock back and forth, thereby driving the molten metal inside it to rock, thereby increasing the contact area between the molten metal and the inner wall of the mold barrel 51. When the overflow hole 5521 moves to the same height as the horizontal support pipe 554, the high-pressure water will pass through the horizontal support pipe 554 into the annular water reservoir 555, and then be sprayed onto the outer wall of the mold barrel 51 through the water spray valve, and finally be contained in the volume formed between the side skirt 56 and the side wall of the mold barrel 51. The water vapor collected by the nanotrough can quickly cool the molten metal inside the mold barrel 51. During the cooling process, the water flow sprayed by the water spray valve will quickly vaporize after contacting the outer wall of the mold barrel 51. The vaporized water vapor can increase the pressure inside the smelting chamber 2. When the pressure reaches the preset value, the vacuum valve 23 will open. At this time, the water vapor inside the smelting chamber 2 will be quickly discharged through the vacuum valve 23. During the discharge process, the water vapor can take away the heat of the molten metal and the waste gas generated by the metal material during the melting process, thereby improving the quality of the alloy ingot. After the molten metal inside the mold barrel 51 is cooled into an alloy ingot, the cavity door 24 is manually opened, and the alloy ingot is taken out for subsequent operations through the existing lifting equipment.

[0064] Fourth: After the melting crucible 33 is reset, the connecting frame 34 and the melting crucible 33 are rotated 90 degrees in the opposite direction by the driving motor 35, and then the electric push rod 71 is started, and the electric push rod 71 drives the electromagnet block 72, the horizontal shaft 73, the heat insulation cylinder 74, the transition rod 75 and the slag scraper 76 to move into the melting crucible 33. When the slag scraper 76 contacts the side wall of the melting crucible 33, the electromagnet block 72 is energized, and then the electric push rod 71 continues to push, and the electromagnetic The iron block 72 will move toward the insulating tube 74, and eventually the electromagnet block 72 will be attracted to the end of the insulating tube 74. At the same time, the slag scraper teeth 76 will move to a state of contact with the inner wall of the smelting crucible 33. Then, the electric push rod 71 will drive the electromagnet block 72, the horizontal shaft 73, the insulating tube 74, the transition rod 75 and the slag scraper teeth 76 to move as a whole away from the smelting crucible 33, so that the slag inside the smelting crucible 33 is scraped into the slag filter tube 6 by the slag scraper teeth 76.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
