Description

Technical Field

[0001] This invention relates to the field of metal smelting technology, and more particularly to a smelting apparatus for casting copper alloys. Background Technology

[0002] Casting is one of the earliest metal heat treatment processes mastered by mankind. It involves pouring liquid metal into a casting cavity that conforms to the shape of the part, and then cooling and solidifying it to obtain the part or blank. Copper alloys are alloys made by adding one or more other alloying elements to pure copper as the base. Depending on the application requirements, different types and proportions of alloys can be added for smelting. Therefore, to realize the casting production of copper alloys, it is necessary to use a smelting device to smelt the raw materials.

[0003] During the smelting of copper alloy furnace charge, solid residues in the charge form a layer of slag on the surface of the liquid metal. When adding furnace charge, the charge will be mixed with slag and sink to the bottom, which seriously affects the quality of the final alloy product. Current smelting equipment still relies on traditional ladle to clean the slag, which is not very effective. Furthermore, furnace charge can only be added after the slag has been cleaned, which affects smelting efficiency. Summary of the Invention

[0007] As a further aspect of the present invention: a plurality of feeding holes are provided through the fixed material plate, and a plurality of screening holes are provided through the screening plate. The screening holes and the feeding holes have the same diameter, and the arrangement of the screening holes is consistent with that of the feeding holes.

[0008] As a further embodiment of the present invention: a plurality of scraper rods are evenly arranged circumferentially at the top end of the feed pipe, the scraper rods are attached to the surface of the discharge ramp, the top end of the scraper rods is fixedly connected to the screen plate, and two adjacent scraper rods form a groove between their bottom ends.

[0009] As a further embodiment of the present invention: a lifting control rod is fixedly provided at the center of the upper end of the fixed material placement plate, the bottom end of the lifting control rod is rotatably engaged with the top end of the synchronous rod, a cover is connected to the bottom end of the synchronous rod, the cover is engaged with the slot, and a plurality of oil-absorbing felt rollers are evenly connected to the outer wall of the synchronous rod.

[0010] As a further embodiment of the present invention: a slag inlet is provided on one side of the slag cleaning filter cylinder along the axial direction, the slag inlet is connected to the slag cleaning filter cylinder, a slider is provided at the upper end of the slag cleaning filter cylinder, a cylinder cover is rotatably installed at the top of the discharge cylinder, a slide rail is provided at the bottom end of the discharge cylinder, and the slider is adapted to slide within the slide rail.

[0011] As a further embodiment of the present invention: a horizontal screw is coaxially arranged inside the slag cleaning filter cylinder, and the two ends of the horizontal screw are respectively rotatably engaged with the slag cleaning filter cylinder and the feed pipe. One end of the horizontal screw is fixedly sleeved with a mating tooth, and the other end of the horizontal screw is threaded through with a scraper plate. The scraper plate is adapted to slide and install in the inner cavity of the slag cleaning filter cylinder.

[0012] As a further aspect of the present invention: blades are provided on the inner wall of the feed pipe, and an extension shell is provided on the outer side of the feed pipe. The blades are rotatably installed inside the extension shell via a pivot. The two ends of the pivot pass through the extension shell and are rotatably engaged with the extension shell via torsion springs. Synchronous teeth are fixedly sleeved at both ends of the pivot, and the synchronous teeth mesh with corresponding mating teeth.

[0013] As a further aspect of the present invention: a slag discharge cover is detachably provided at the bottom of the slag collection box, and the bottom end of the feed pipe extends through and out of the slag discharge cover.

[0014] As a further aspect of the present invention: a sealing cover for sealing the furnace is connected to one side of the crucible, a tilting motor is installed inside the sealing cover, the output end of the tilting motor is fixedly connected to the outer wall of the crucible, the tilting motor is fixedly installed in a fixed frame, a support guide rod is fixedly connected to one side of the fixed frame, and the support guide rod is slidably installed through the side wall of the furnace frame.

[0015] The beneficial effects of this invention are: (1) By setting up a feeding cylinder, when preparing to melt copper alloy, the crucible is pulled into the furnace by using a telescopic control rod. During the melting process, the feeding cylinder is gradually lowered by using a lifting screw until the slag removal filter cylinder extends into the surface of the liquid metal in the crucible. At this time, the feeding pipe is controlled to start rotating. On the one hand, the feeding pipe will drive the top screen plate to rotate synchronously and cooperate with the fixed feeding plate to screen and separate the furnace material with uniform particle size. The screened furnace material falls onto the feeding ramp to prepare for feeding. On the other hand, the feeding pipe will drive the bottom slag removal filter cylinder to rotate synchronously. The slag removal filter cylinders on both sides can effectively collect and clean the slag on the surface of the liquid metal in the crucible. After the slag is cleaned, the furnace material enters the crucible through the feeding pipe for melting, thereby effectively avoiding the addition of slag to the bottom when adding furnace material and effectively improving the melting process quality.

[0016] (2) By setting a synchronizing rod, when the lifting control rod drives the synchronizing rod to move down until the cover at the bottom of the synchronizing rod engages with the slot, the cover will close the top of the feed pipe. During the process of removing slag, the feed pipe will drive the screen plate, scraper and synchronizing rod to rotate simultaneously. The screen plate will rotate to screen the material in cooperation with the fixed material plate. The furnace material falling on the feeding ramp will be continuously scraped and turned over by the rotating scraper. At the same time, the synchronizing rod drives the oil-absorbing felt roller to rotate synchronously, so that the oil-absorbing felt roller can fully mix and contact with the constantly turning furnace material. The oil-absorbing characteristics of the oil-absorbing felt roller can effectively remove the oil stains on the surface of the furnace material, so that the furnace material is kept dry and clean, which is conducive to improving the smelting quality.

[0017] (3) By setting up a scraper, when cleaning the slag, the slag is collected in the inner cavity of the slag cleaning filter. After the slag is cleaned, the furnace charge is prepared to be fed. The furnace charge falls directly into the crucible through the feed pipe. During this process, the furnace charge falling continuously in the feed pipe will continuously impact the blades, causing the blades to rotate continuously with the falling furnace charge, thereby driving the pivot to rotate. The pivot drives the synchronous teeth at both ends to rotate. The synchronous teeth drive the horizontal screws at both ends to rotate through the mating teeth. The horizontal screws will drive the corresponding scraper to move linearly along the axis of the slag cleaning filter, thereby scraping off the slag accumulated in the inner cavity of the slag cleaning filter, so that the slag is pushed into the slag collection box for collection. Thus, the slag scraping process in the inner cavity of the slag cleaning filter can be realized when feeding, avoiding the accumulation of slag in the slag cleaning filter and affecting the next slag cleaning.

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. 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] Please see Figures 1-6 and Figure 9 As shown, this invention is a smelting apparatus for casting copper alloys, including a furnace 1, a supporting furnace frame 2 extending from one side of the furnace 1, a feeding cylinder 3 at the upper end of the furnace 1, a crucible 4 inside the furnace 1, the feeding cylinder 3 located directly above the crucible 4, a feeding slot 201 penetrating through the supporting furnace frame 2, a telescopic control rod 101 fixedly mounted on one side of the furnace 1 for pushing the crucible 4 to the feeding slot 201, the output end of the telescopic control rod 101 rotatably engaging with the side wall of the crucible 4, a lifting screw 202 rotatably mounted on the upper end of the supporting furnace frame 2, a support plate 301 extending from one side of the feeding cylinder 3, the lifting screw 202 threaded through the support plate 301, and a fixed feeding plate 304 and a feeding ramp 304 sequentially arranged from top to bottom on the inner wall of the feeding cylinder 3. 5 and fixed plate 306, the bottom center of the feeding ramp 305 is coaxially provided with feeding pipe 5, feeding pipe 5 is rotatably installed on fixed plate 306, the top end of feeding pipe 5 is connected to screen plate 502, screen plate 502 is rotatably installed on the bottom of fixed material plate 304 for rotating screening, the outer wall of feeding pipe 5 is provided with slag cleaning assembly 6, slag cleaning assembly 6 includes a set of slag cleaning filter cylinder 601 and slag collection box 602, the slag cleaning filter cylinder 601 is symmetrically arranged on both sides of slag collection box 602 and is connected to slag collection box 602, the bottom of feeding pipe 5 passes through slag collection box 602 and extends out from the bottom of slag collection box 602, slag collection box 602 is fixed to the outer wall of feeding pipe 5, and the feeding pipe 5 drives the slag cleaning filter cylinder 601 to rotate horizontally to remove floating slag.

[0033] Specifically, by setting up the feeding cylinder 3, when preparing to melt copper alloy, the crucible 4 is drawn into the furnace 1 using the telescopic control rod 101. During the melting process, the feeding cylinder 3 is gradually lowered using the lifting screw 202 until the slag removal filter cylinder 601 extends into the surface of the liquid metal in the crucible 4. At this time, the feeding pipe 5 is controlled to start rotating. On the one hand, the feeding pipe 5 will drive the top screening plate 502 to rotate synchronously, and cooperate with the fixed feeding plate 304 to screen and separate the furnace charge with uniform particle size. The screened furnace charge falls onto the discharge ramp 305 for discharge. On the other hand, the feeding pipe 5 will drive the bottom slag removal filter cylinder 601 to rotate synchronously. The slag removal filter cylinders 601 on both sides can effectively collect and clean the slag on the surface of the liquid metal in the crucible 4. After the slag is cleaned, the furnace charge enters the crucible 4 through the feeding pipe 5 for melting, thereby effectively avoiding the addition of slag to the bottom when adding furnace charge, and effectively improving the melting process quality.

[0034] It should be noted that fine holes are provided through the outer walls of the slag cleaning filter cylinder 601 and the slag collection box 602 in this embodiment, so that the liquid metal contained in the slag can flow back into the crucible 4 through the holes, avoiding resource waste, and at the same time, it can effectively filter and block the slag, preventing the slag from being mixed into the liquid metal.

[0035] like Figure 5 and Figure 9 As shown, a rotary motor 307 is fixed on the fixed plate 306. The output end of the rotary motor 307 is connected to a drive gear 3071. A transmission gear 503 is fixedly sleeved on the outer wall of the feed pipe 5. The drive gear 3071 meshes with the transmission gear 503.

[0036] Specifically, the rotation of the feed pipe 5 is achieved by the rotary motor 307. When the rotary motor 307 starts, it drives the drive gear 3071 to rotate, and the drive gear 3071 drives the transmission gear 503 to rotate, thereby realizing the rotation control process of the feed pipe 5.

[0037] like Figure 5 and Figure 6 As shown, a number of feeding holes 3041 are provided through the fixed feeding plate 304, and a number of screening holes 5021 are provided through the screening plate 502. The screening holes 5021 and the feeding holes 3041 have the same diameter, and the arrangement of the screening holes 5021 is consistent with that of the feeding holes 3041.

[0038] Specifically, by setting a fixed feeding plate 304 and a sieve plate 502, the sieve hole 5021 of the sieve plate 502 will intermittently align with the discharge hole 3041 during the rotation of the sieve plate 502. When the two holes are aligned, the furnace charge on the fixed feeding plate 304 will fall sequentially through the discharge hole 3041 and the sieve hole 5021 onto the discharge ramp 305, thereby screening out furnace charge particles of uniform size to ensure smelting quality. When the two holes are staggered, the furnace charge will be blocked. At the same time, the opening and closing of the discharge can be controlled by the rotation of the sieve plate 502, and the intermittent discharge process can precisely control the discharge amount, avoiding excessive discharge of furnace charge at one time, which would interfere with the composition of the smelted alloy.

[0039] like Figures 6-8 As shown, a number of scraper rods 501 are evenly arranged around the top of the feed pipe 5. The scraper rods 501 are attached to the surface of the discharge inclined platform 305. The top of the scraper rods 501 is fixedly connected to the screen plate 502. Two adjacent scraper rods 501 form a groove 5011 between their bottoms.

[0040] Furthermore, a lifting control rod 308 is fixedly installed at the center of the upper end of the fixed material plate 304. The bottom end of the lifting control rod 308 is rotatably engaged with the top end of the synchronous rod 309. A cover 3091 is connected to the bottom end of the synchronous rod 309. The cover 3091 is engaged with the slot 5011. Several oil-absorbing felt rollers 3092 are evenly connected to the outer wall of the synchronous rod 309.

[0041] Specifically, by setting a synchronizing rod 309, when the lifting control rod 308 drives the synchronizing rod 309 to move downwards until the cover 3091 at the bottom of the synchronizing rod 309 engages with the slot 5011, the cover 3091 closes the top of the feed pipe 5. During the process of removing scum, the feed pipe 5 rotates continuously. Because the top of the synchronizing rod 309 is engaged with the lifting control rod 308, the feed pipe 5 will drive the screen plate 502, the scraper rod 501, and the synchronizing rod 309. Simultaneously rotating, the screen plate 502, in conjunction with the fixed material placement plate 304, rotates to screen the material. The furnace charge falling onto the discharge ramp 305 will be continuously scraped and turned over by the rotating scraper 501. At the same time, the synchronizing rod 309 drives the oil-absorbing felt roller 3092 to rotate synchronously, so that the oil-absorbing felt roller 3092 can fully mix and contact with the continuously turning furnace charge. Utilizing the oil-absorbing characteristics of the oil-absorbing felt roller 3092, the oil stains on the surface of the furnace charge can be effectively removed, keeping the furnace charge dry and clean, which is conducive to improving the smelting quality.

[0042] After the slag is removed, the feed pipe 5 stops rotating. At this time, the lifting control rod 308 is driven to rise synchronously until the cover 3091 disengages from the slot 5011. At this point, the top of the feed pipe 5 opens, and the furnace charge on the discharge ramp 305 will fall directly into the crucible 4 through the feed pipe 5 for melting. The opening and closing process of the feed pipe 5 is realized by the cooperation of the cover 3091 and the slot 5011, so that the slag removal process and the discharge process can be carried out independently and orderly, avoiding the mixing of slag and sinking to the bottom of the furnace charge during the discharge process.

[0043] like Figure 4 and Figure 9 As shown, a slag inlet 6011 is provided on one side of the slag cleaning filter cylinder 601 along the axial direction. The slag inlet 6011 is connected to the slag cleaning filter cylinder 601. A slider 6012 is provided at the upper end of the slag cleaning filter cylinder 601. A cylinder cover 302 is rotatably installed at the top of the discharge cylinder 3. A slide rail 303 is provided at the bottom end of the discharge cylinder 3. The slider 6012 is adapted to slide and install in the slide rail 303.

[0044] Specifically, during the removal of scum, the feed pipe 5 drives the scum removal filter cylinder 601 to rotate continuously. The scum on the surface of the liquid metal will be caught through the scum inlet 6011 and enter the scum removal filter cylinder 601. During this process, the scum removal filter cylinder 601 always maintains circumferential rotation on the slide rail 303 through the slider 6012, ensuring the stability during rotational scum removal.

[0045] like Figure 10 and Figure 11 As shown, a horizontal screw 603 is coaxially arranged inside the slag cleaning filter cylinder 601. The two ends of the horizontal screw 603 are rotatably engaged with the slag cleaning filter cylinder 601 and the feed pipe 5, respectively. One end of the horizontal screw 603 is fixedly sleeved with a mating tooth 6031, and the other end of the horizontal screw 603 is threaded through with a scraper plate 604. The scraper plate 604 is adapted to slide and install in the inner cavity of the slag cleaning filter cylinder 601.

[0046] Furthermore, a blade 504 is provided on the inner wall of the feed pipe 5, and an extension shell 5041 is provided on the outer side of the feed pipe 5. The blade 504 is rotatably installed inside the extension shell 5041 via a pivot 5042. Both ends of the pivot 5042 pass through the extension shell 5041 and are rotatably engaged with the extension shell 5041 via a torsion spring 5044. Synchronizing teeth 5043 are fixedly sleeved at both ends of the pivot 5042, and the synchronizing teeth 5043 mesh with the corresponding mating teeth 6031.

[0047] Specifically, by setting up a scraper 604, the scum is collected in the inner cavity of the scum cleaning filter cylinder 601 during scum removal. After the scum is removed, the furnace charge is prepared for feeding. The furnace charge falls directly into the crucible 4 through the feed pipe 5. During this process, the furnace charge continuously falling into the feed pipe 5 will continuously impact the blades 504, causing the blades 504 to rotate continuously with the falling furnace charge, thereby driving the pivot 5042 to rotate. The pivot 5042 drives the synchronous gears 5043 at both ends to rotate. The synchronous gears 5043 are matched with... The gear 6031 drives the horizontal screws 603 at both ends to rotate. The horizontal screws 603 drive the corresponding scraper 604 to move linearly along the axis of the cleaning filter cylinder 601, thereby scraping away the floating scum accumulated in the inner cavity of the cleaning filter cylinder 601. The floating scum is pushed into the scum collection box 602 for collection. This process of scraping away floating scum in the inner cavity of the cleaning filter cylinder 601 during material feeding avoids the accumulation of floating scum in the cleaning filter cylinder 601, which would affect the next cleaning.

[0048] It should be noted that during the process of the blade 504 being impacted and causing the pivot 5042 to rotate, the torsion springs 5044 at both ends of the pivot 5042 will simultaneously twist and accumulate potential energy. After the material is discharged, the blade 504 is no longer subjected to impact. At this time, the torsion springs 5044 will release elastic potential energy, causing the pivot 5042 to rotate in the opposite direction, thereby causing the horizontal screws 603 at both ends to rotate in the opposite direction as well, which in turn causes the corresponding scraper 604 to move in the opposite linear direction until the scraper 604 moves back to the farthest end of the cleaning filter cylinder 601 to prepare for the next scraping process.

[0049] like Figure 9 As shown, the bottom of the slag collection box 602 is detachably equipped with a slag discharge cover plate 6021. The bottom end of the feed pipe 5 passes through and extends out of the slag discharge cover plate 6021. By removing the slag discharge cover plate 6021, the floating slag collected in the slag collection box 602 can be uniformly discharged and cleaned.

[0050] like Figures 1-3 As shown, a sealing cover 401 for sealing the furnace 1 is connected to one side of the crucible 4. A tilting motor 402 is installed inside the sealing cover 401. The output end of the tilting motor 402 is fixedly connected to the outer wall of the crucible 4. The tilting motor 402 is fixedly installed in the fixing frame 403. A support guide rod 404 is fixedly connected to one side of the fixing frame 403. The support guide rod 404 is slidably installed on the side wall of the supporting furnace frame 2.

[0051] Specifically, after the smelting is completed, the lifting screw 202 is used to control the discharge cylinder 3 to rise, making room for the horizontal movement of the crucible 4. Then, the telescopic control rod 101 pushes the crucible 4 horizontally out of the furnace 1 until the crucible 4 reaches the position of the discharge slot 201. During this process, the support guide rod 404 can provide support and guidance for the horizontal pushing of the crucible 4, keeping it balanced and stable. Then, the tilting motor 402 is used to control the crucible 4 to gradually rotate and tilt, thereby pouring out the liquid metal inside the crucible 4.

[0052] The working principle of this invention is as follows: Figures 1-11As shown, when preparing to smelt copper alloy, the crucible 4 is pulled into the furnace 1 using the telescopic control rod 101. During the smelting process, the discharge cylinder 3 is gradually lowered using the lifting screw 202 until the slag removal filter cylinder 601 extends into the surface of the liquid metal in the crucible 4. The lifting control lever 308 drives the synchronizing lever 309 to move down until the cover 3091 at the bottom of the synchronizing lever 309 engages with the slot 5011. At this time, the cover 3091 closes the top of the feed pipe 5, and the feed pipe 5 starts to rotate. The feed pipe 5 will drive the screen plate 502, the scraper 501 and the synchronizing lever 309 to rotate simultaneously. The screen plate 502, in conjunction with the fixed material plate 304, rotates to screen the material. The furnace charge falling on the discharge ramp 305 will be continuously scraped and turned over by the rotating scraper 501. At the same time, the synchronizing lever 309 drives the oil-absorbing felt roller 3092 to rotate synchronously, so that the oil-absorbing felt roller 3092 can fully mix and contact with the constantly turning furnace charge. The oil-absorbing characteristics of the oil-absorbing felt roller 3092 can effectively remove the oil stains on the surface of the furnace charge, keeping the furnace charge dry and clean. At the same time, the feed pipe 5 will drive the bottom slag cleaning filter 601 to rotate synchronously. The slag cleaning filter 601 on both sides will be able to effectively collect and clean the slag on the surface of the liquid metal in the crucible 4. After the slag is cleaned, the feed pipe 5 stops rotating. At this time, the lifting control rod 308 is driven to rise synchronously until the cover 3091 is separated from the slot 5011. At this time, the top of the feed pipe 5 opens, and the furnace charge on the feeding ramp 305 will fall directly into the crucible 4 through the feed pipe 5 for melting. The continuously falling furnace charge inside the feed pipe 5 will continuously impact the blades 504, causing the blades 504 to rotate continuously with the falling furnace charge, thereby driving the pivot 5042 to rotate. The pivot 5042 drives the synchronous gears 5043 at both ends to rotate. The synchronous gears 5043 drive the horizontal screws 603 at both ends to rotate through the mating gears 6031. The horizontal screws 603 will drive the corresponding scraper plates 604 to move linearly along the axis of the slag cleaning filter cylinder 601, thereby scraping off the floating slag accumulated in the inner cavity of the slag cleaning filter cylinder 601, so that the floating slag is pushed into the slag collection box 602 for collection. After smelting, the lifting screw 202 is used to control the discharge cylinder 3 to rise, making room for the horizontal movement of the crucible 4. Then, the telescopic control rod 101 pushes the crucible 4 horizontally out of the furnace 1 until the crucible 4 reaches the position of the discharge slot 201. During this process, the support guide rod 404 can provide support and guidance for the horizontal pushing of the crucible 4, keeping it balanced and stable. Then, the tilting motor 402 is used to control the crucible 4 to gradually rotate and tilt, thereby pouring out the liquid metal inside the crucible 4.

[0053] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
