Description

Technical Field

[0001] The invention relates to the technical field of smelting furnaces, in particular to a smelting furnace capable of automatically skimming slag. Background Art

[0002] In the field of metal smelting, dross removal is a key link in ensuring the purity of the melt and product quality. Traditional smelting furnaces mostly rely on manual slag removal or simple mechanical scraping devices, which have problems such as low efficiency, high operating risks, secondary oxidation of the melt and large heat energy loss. This is especially true for the high-precision smelting of non-ferrous metals such as aluminum and copper and special alloys. The dross has strong adhesion and uneven distribution. Manual intervention can easily lead to temperature fluctuations, affecting the stability of the composition.

[0003] In the existing technology, some automated slag removal equipment uses a single reciprocating mechanism to drive a scraper to remove slag. However, due to the limitation of the single motion trajectory, it is difficult to cover the entire area of ​​the molten pool surface, and there are blind spots for cleaning. Although the complex mechanical structure with multiple power sources can improve the coverage rate, it leads to high energy consumption and increased maintenance costs. In addition, the traditional filter-type slag removal device is prone to reducing the filtration efficiency due to slag blockage, and the slag discharge process relies on gravity dropping, which makes it difficult to completely remove the adhesive slag. Frequent shutdown for cleaning is required, affecting continuous production. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above difficulties and provide a smelting furnace capable of automatic slag removal.

A reversing slide rod and a directional slide plate are provided on the slag scoop column, and the reversing slide rod and the directional slide plate alternately slide with the reciprocating chute.

[0007] As an improvement, a reciprocating bracket is provided at the upper end of the reciprocating slide rod, and the reciprocating bracket rotates in cooperation with the connecting rotating column. A positioning rotating frame is provided at the lower end of the reciprocating slide rod. A matching rotating column is rotatably provided on the movable frame. A matching slide rod and a reciprocating fork are respectively provided at both ends of the matching rotating column. The reciprocating fork rotates in cooperation with the positioning rotating frame, and the matching slide rod swings back and forth as the slag scooping rotating column rotates.

[0008] As an improvement, a one-way turntable is provided on one side of the slag scooping column, and a one-way slide groove is provided on the one-way turntable for sliding cooperation with the matching slide rod, and the one-way slide groove is an 8-shaped structure.

[0009] As an improvement, the slag filter cartridge is a bucket-shaped structure with openings at both ends. A slag slide is provided in the slag filter cartridge, and a slag filter plate is slidably provided on the slag slide. The cross-section of the slag filter plate is a trapezoidal structure.

[0010] As an improvement, the movable frame is provided with a collecting bucket, the inner diameter of the collecting bucket is larger than the outer diameter of the lower end of the slag filter cylinder, and the collecting bucket is provided with a collecting top rod that cooperates with the slag filter plate. The movable frame is provided with a collecting pipe connected to the collecting bucket, and the collecting pipe extends out of the furnace body.

[0011] As an improvement, the driving mechanism includes a driving box arranged on one side of the furnace body, a driving sprocket driven by a motor is provided in the driving box, a reversing sprocket is provided in the driving box, a driving electric push rod is provided on the driving box, an adjusting sprocket is provided for rotating the telescopic end of the driving electric push rod, a one-way sprocket is provided on one side of the one-way turntable, and a driving chain is provided on the driving sprocket that passes through the adjusting sprocket, the one-way sprocket and the reversing sprocket in sequence.

[0012] As an improvement, a collecting plate is rotatably provided at the lower end of the movable frame, and the collecting plate is an arc-shaped structure. A fixed bevel gear is provided on the collecting plate. A collecting column is rotatably provided on the movable frame, and a reversing bevel gear meshing with the fixed bevel gear is provided at one end of the collecting column, and a collecting bevel gear is provided at the other end of the collecting column. A collecting column is rotatably provided on the movable frame, and a matching bevel gear meshing with the collecting bevel gear is provided at one end of the collecting column, and a collecting bevel gear is provided at the other end of the collecting column. One end of the slag scooping column is provided with a driving bevel gear meshing with the collecting bevel gear.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the electric push rod drives the mobile frame to position flexibly, the mechanical linkage design of the reciprocating sleeve and the slide rod in the slag scooping mechanism enables the slag scooping filter cartridge to form an N-shaped trajectory under the compound motion, thereby achieving full coverage and scooping of the slag on the surface of the molten pool; the bucket shape with openings at both ends of the slag scooping filter cartridge cooperates with the trapezoidal slag scooping filter plate to grade and intercept the slag, and the automatic forced discharge of the slag is achieved through the collection push rod and the negative pressure system; at the same time, the arc-shaped collecting plate driven by the integrated bevel gear synchronously gathers the slag, forming an integrated closed process of "slag scooping-collecting-slag discharge", which has the advantages of fast heating speed, high slag scooping efficiency, low energy consumption, and high degree of automation. It is particularly suitable for the high-cleanliness continuous production requirements of non-ferrous metal smelting. Specifically:

[0014] 1. The rigidity of the mobile frame is enhanced by combining longitudinal and oblique support frames. The continuous rotation of the slag scoop is converted into the alternating two-way rotation of the reciprocating casing and the periodic expansion and contraction of the slide bar. At the same time, the 8-shaped one-way chute constrains the slide bar's swing trajectory, driving the reciprocating slide bar to form a compound motion of "lifting-horizontal swinging". Ultimately, the slag filter achieves efficient slag scooping with precise three-dimensional coverage of the molten pool surface. Its mechanical linkage design does not require an additional power source, and the synergistic effect of the cross chute and the one-way chute effectively prevents jamming. It combines the advantages of high motion stability, strong fatigue resistance, and a high degree of automation, making it suitable for continuous operation requirements in high-temperature smelting environments.

[0015] 2. The slag filter cartridge adopts a bucket-shaped structure with open ends and a trapezoidal cross-section slag filter plate design. The tapered filter channel guides the slag to the center. Combined with the mechanical push of the collecting ejector and the negative pressure system, the slag is intercepted and forced to be discharged in a graded manner. The tolerance design of the collecting bucket inner diameter ensures the precise alignment of the filter cartridge. The external negative pressure quickly extracts the slag, forming a closed and automated slag discharge process, effectively avoiding filter hole blockage and heat loss. It has the advantages of high filtration efficiency, thorough slag discharge, stable structure, and environmental friendliness. It is suitable for continuous and efficient slag removal in high-temperature smelting scenarios.

[0016] 3. The aggregate plate is designed with a bevel gear linkage transmission to synchronously transmit the power of the slag scooping column to the arc-shaped aggregate plate, thereby realizing the directional gathering and pushing of the slag. The fixed bevel gear and the reversing bevel gear are engaged to force the aggregate plate to rotate in the opposite direction. Combined with the centrifugal force of the arc structure, the slag is efficiently swept. Its action sequence is precisely matched with the slag scooping filter cartridge to form a continuous cycle of "slag gathering - scooping - slag discharge". Power reuse reduces energy consumption. The high-temperature resistant material and modular design of the bevel gear ensure transmission stability and load resistance, reduce molten pool disturbance, and improve the cleanliness of the metal melt. It is suitable for high-precision automated smelting scenarios of non-ferrous metals. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5As shown, a smelting furnace with automatic slag removal includes a furnace body 1, on which a heating mechanism 11 is provided. The heating mechanism 11 is an induction heating mechanism 11. Through the principle of electromagnetic induction, an alternating magnetic field is generated by a copper induction coil surrounding the furnace body 1, so that eddy currents are generated inside the metal charge to generate heat. This heating method has fast heating speed, high efficiency, and precise temperature control. It is suitable for the smelting of non-ferrous metals (such as aluminum, copper) and special alloys. A supporting mechanism 2 is provided on the inside of the furnace body 1. The furnace body 1 is connected to a slag scooping mechanism 3 through the supporting mechanism 2. A driving mechanism 4 for driving the slag scooping mechanism 3 is provided on one side of the furnace body 1. A collecting mechanism 5 for collecting slag as the slag scooping mechanism 3 moves is provided in the furnace body 1. The supporting mechanism 2 includes a sliding mechanism arranged on the inside of the furnace body 1. The movable frame 27 is provided with a supporting electric push rod 26 on the outside of the furnace body 1 for driving the movable frame 27 to move. The slag scooping mechanism 3 includes a reciprocating sleeve 31 rotatably arranged on the movable frame 27, and a reciprocating slide 32 is slidably provided in the reciprocating sleeve 31. A connecting rotating column 33 is rotatably provided at one end of the reciprocating slide 32. A connecting slide 331 is slidably sleeved on the connecting rotating column 33, and a connecting rod 332 is provided on the connecting slide 331. A connecting rocker 333 rotatably connected to the movable frame 27 is provided on the connecting rod 332. A slag scooping filter cartridge 34 is provided at the lower end of the connecting rotating column 33. A slag scooping rotating column 35 for driving the reciprocating sleeve 31 to rotate back and forth is rotatably provided on the movable frame 27. A one-way turntable 36 for driving the reciprocating slide 32 to slide back and forth is provided on one side of the slag scooping rotating column 35.

[0029] The working principle of the present invention is as follows: the heating mechanism 11 adopts induction heating, and operates on the principle of electromagnetic induction through a copper induction coil surrounding the furnace body 1. When the induction coil is connected to an alternating current, an alternating magnetic field is generated. The metal charge placed in the furnace body 1 is exposed to this alternating magnetic field, and an induced electromotive force is generated therein, thereby forming eddy currents. According to Joule's law, the eddy currents flowing within the metal charge generate heat, thereby achieving heating of the metal charge.

[0030] The movable frame 27 of the support mechanism 2 is slidably arranged inside the furnace body 1. The supporting electric push rod 26 outside the furnace body 1 is the power source for its movement. When the position of the slag collecting mechanism 3 needs to be adjusted, the supporting electric push rod 26 is activated, and the movable frame 27 is pushed to slide inside the furnace body 1 through telescopic movement. The sliding of the movable frame 27 can drive the slag collecting mechanism 3 connected thereto to move to different positions inside the furnace body 1, so that the slag collecting mechanism 3 can salvage and collect slag in different areas of the furnace body 1.

[0031] The driving mechanism 4 drives the slag scooping column 35 to rotate. When the slag scooping column 35 rotates, it drives the reciprocating sleeve 31 to reciprocate. The one-way turntable 36 also rotates with the rotation of the slag scooping column 35. The one-way turntable 36 drives the reciprocating slide bar 32 to slide back and forth in the reciprocating sleeve 31. Under the combined action of the reciprocating rotation of the reciprocating sleeve 31 and the reciprocating sliding of the reciprocating slide bar 32, the connecting column 33 performs a complex spatial motion. The connecting slide plate 331 slidably sleeved on the connecting column 33 and the rotatably arranged connecting rocker bar 333 can guide and stabilize the movement of the connecting column 33. Finally, the slag scooping drum 34 at the lower end of the connecting column 33 will perform an N-shaped trajectory movement in the furnace body 1 to realize the salvage of slag. The filter screen structure of the slag scooping drum 34 can allow liquid metal to pass through and intercept the slag in the slag scooping drum 34.

[0032] The collecting mechanism 5 is arranged in the furnace body 1. As the slag scooping mechanism 3 moves, when the slag scooping filter cylinder 34 is full of slag, the slag scooping mechanism 3 moves the slag scooping filter cylinder 34 to the top of the collecting mechanism 5. At this time, the slag scooping filter cylinder 34 descends, and the slag in the slag filter cylinder 34 enters the collecting mechanism 5, completing the slag collection work.

[0033] Combined with attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 9 As shown, the movable frame 27 includes an upper support frame 21 and a lower support frame 22, the lower support frame 22 is provided with a longitudinal support frame 23 and an oblique support frame 24, the reciprocating sleeve 31 is rotatably arranged on the upper support frame 21, and a reciprocating chute 311 is penetrated by the reciprocating sleeve 31, and the reciprocating chute 311 is symmetrically cross-arranged, and the slag scooping column 35 is provided with a reversing slide bar 351 and a directional slide plate 352, and the reversing slide bar 351 and the directional slide plate 352 alternately slide with the reciprocating slide bar 311;

[0034] The upper end of the reciprocating slide 32 is provided with a reciprocating bracket 321, which rotates with the connecting rotating column 33, and the lower end of the reciprocating slide 32 is provided with a positioning rotating frame 322. A matching rotating column 363 is rotatably provided on the longitudinal support frame 23, and a matching slide 364 and a reciprocating fork 365 are respectively provided at both ends of the matching rotating column 363. The reciprocating fork 365 rotates with the positioning rotating frame 322, and the matching slide 364 swings back and forth as the slag scooping rotating column 35 rotates. A one-way turntable 36 is provided on one side of the slag scooping rotating column 35, and a one-way slide groove 361 is provided on the one-way turntable 36 to slide with the matching slide 364, and the one-way slide groove 361 is an 8-shaped structure.

[0035] The movement principle of the reciprocating slide 32: When the slag scooping column 35 rotates, the reversing slide 351 and the directional slide plate 352 on it slide alternately into the reciprocating slide 311 (symmetrical cross slide), forcing the reciprocating sleeve 31 to reciprocate around the axis, driving the internal reciprocating slide 32 to reciprocate around the axis synchronously. The cross design of the reciprocating slide 311 converts the continuous rotation of the slag scooping column 35 into the forward and reverse alternating rotation of the sleeve, realizing the periodic alternating rotation of the slide, thereby driving the connecting column 33 to cyclically move between the slag scooping point and the slag discharge point. The positioning rotary frame 322 at the lower end of the reciprocating slide 32 is linked to the matching column 363 through the reciprocating fork 365, and the matching rotary The mating slide 364 at the other end of the column 363 is constrained by the 8-shaped one-way slide groove 361 on the one-way turntable 36, forcing the mating slide 364 to swing. The swing of the mating slide 364 is transmitted to the reciprocating fork 365 through the mating rotating column 363, driving the positioning rotating frame 322 to drive the reciprocating slide 32 to move up and down. At the same time, the rotation of the reciprocating sleeve 31 causes the reciprocating slide 32 to swing horizontally, and finally transmits the composite motion to the slag filter drum 34 through the connecting rotating column 33. Under the composite motion of "lifting-rotating-swinging", the slag filter drum 34 is immersed in the surface of the molten pool, collects the slag, separates the slag through the filter holes, and transfers the slag to the collection mechanism 5.

[0036] Combined with attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 9 As shown, the slag filter cylinder 34 is a bucket-shaped structure with openings at both ends. A slag slide 341 is provided in the slag filter cylinder 34, and a slag filter plate 342 is slidably provided on the slag slide 341. The cross-section of the slag filter plate 342 is a trapezoidal structure. A collecting bucket 25 is provided on the movable frame 27. The inner diameter of the collecting bucket 25 is larger than the outer diameter of the lower end of the slag filter cylinder 34. A collecting top rod 251 is provided in the collecting bucket 25 to cooperate with the slag filter plate 342. A collecting pipe 252 is provided on the movable frame 27 to communicate with the collecting bucket 25. The collecting pipe 252 extends out of the furnace body 1 and is communicated with an external slag collecting device, which can generate negative pressure.

[0037] The working principle of the slag filter cartridge 34 and the collecting bucket 25 is as follows: the slag filter cartridge 34 (bucket-shaped structure) is immersed in the surface of the molten pool through a composite movement. The openings at both ends allow the slag on the surface of the molten pool to flow into the slag filter cartridge 34 along with the melt. The slag filter plate 342 (trapezoidal cross-section) slides along the slag slide bar 341 to form a "wide to narrow" filtering channel in the slag filter cartridge 34. The trapezoidal slope is used to guide the slag to gather in the center of the slag filter cartridge 34. The slag is blocked by the slag filter plate 342 and is taken away from the molten pool as the slag filter cartridge 34 moves. The movable frame 27 drives the slag filter cartridge 34 to move to the top of the collecting bucket 25. The slag filter cartridge 34 is then moved to the top of the collecting bucket 25. The lower end of the collecting hopper 25 is inserted into the collecting hopper 25 (due to the larger inner diameter of the collecting hopper 25, the alignment tolerance is ensured). The collecting push rod 251 in the collecting hopper 25 moves downward with the slag filter cylinder 34 to push the slag filter plate 342, forcing the slag filter plate 342 to slide upward along the slag sliding rod 341. When the slag filter plate 342 enters the wider part of the cross-section of the slag filter cylinder 34, the trapped slag slides down from the trapezoidal cross-section of the slag filter plate 342 under the action of gravity and falls into the collecting hopper 25 through the lower end opening of the slag filter cylinder 34. The slag in the collecting hopper 25 is guided by negative pressure through the connecting pipe and discharged from the furnace body 1 through the collecting pipe 252 and enters the external slag collecting device.

[0038] Combined with attachment Figure 3 , Attachment Figure 4 , Attachment Figure 6 and attached Figure 7 As shown, the driving mechanism 4 includes a driving box 41 arranged on one side of the furnace body 1, a driving sprocket 44 driven by a motor is provided in the driving box 41, a reversing sprocket 43 is provided for rotation in the driving box 41, a driving electric push rod 42 is provided on the driving box 41, an adjusting sprocket 421 is provided for rotation at the telescopic end of the driving electric push rod 42, a one-way sprocket 362 is provided on one side of the one-way turntable 36, and a driving chain 441 is provided on the driving sprocket 44 that passes through the adjusting sprocket 421, the one-way sprocket 362 and the reversing sprocket 43 in sequence.

[0039] The working principle of the driving mechanism 4: After the motor is started, it drives the driving sprocket 44 to rotate, and transmits power to the adjusting sprocket 421, the one-way sprocket 362 and the reversing sprocket 43 through the driving chain 441, forming a closed-loop transmission path. During this process, the telescopic end of the driving electric push rod 42 controls the position of the adjusting sprocket 421, and by pushing or pulling back the adjusting sprocket 421, the tension of the driving chain 441 and the length of the transmission path are adjusted in real time to maintain the transmission stability. The driving chain 441 drives the one-way turntable 36 to rotate in one direction, and through the 8-shaped slide groove thereon, it cooperates with the slide rod 364 to finally convert the power into a compound motion (lifting-rotation-swinging) of the slag filter drum 34.

[0040] Combined with attachment Figure 3 , Attachment Figure 4 , Attachment Figure 8 and attached Figure 9As shown, a collecting plate 54 is rotatably provided at the lower end of the movable frame 27, and the collecting plate 54 is an arc-shaped structure. A fixed bevel gear 53 is provided on the collecting plate 54. A collecting column 52 is rotatably provided on the movable frame 27. A reversing bevel gear 522 meshing with the fixed bevel gear 53 is provided at one end of the collecting column 52, and a collecting bevel gear 521 is provided at the other end of the collecting column 52. A collecting column 51 is rotatably provided on the movable frame 27, and a matching bevel gear 512 meshing with the collecting bevel gear 521 is provided at one end of the collecting column 51, and a collecting bevel gear 511 is provided at the other end of the collecting column 51. One end of the slag scooping column 35 is provided with a driving bevel gear 353 meshing with the collecting bevel gear 511.

[0041] The working principle of the collecting plate 54: When the slag scoop column 35 rotates, the driving bevel gear 353 at its end engages with the collecting bevel gear 511, driving the collecting column 51 to rotate. The matching bevel gear 512 at the other end of the collecting column 51 engages with the collecting bevel gear 521, driving the collecting column 52 to rotate. The reversing bevel gear 522 at the other end of the collecting column 52 engages with the fixed bevel gear 53 (fixed on the collecting plate 54), forcing the collecting plate 54 to rotate in the opposite direction around the rotation axis. 54 (arc-shaped structure) gathers the scattered scum toward the center as it rotates, and cooperates with the compound movement of the scum filter drum 34 to guide the scum to the collection bucket 25. The rotation of the scum rotating column 35 synchronously drives the scum filter drum 34 and the collecting plate 54 to ensure that the timing of scum removal and collection is matched. When the scum filter drum 34 absorbs scum, the collecting plate 54 rotates to gather the surrounding residue. When the scum filter drum 34 discharges scum, the collecting plate 54 pushes the new scum to the operating area of ​​the scum filter drum 34, forming a continuous cleaning cycle.

[0042] When the present invention is implemented, first, pre-operation preparations are carried out, and the appearance of the furnace body 1 is carefully inspected to ensure that there is no damage or cracks, and that all components are firmly connected. The heating mechanism 11 adopts an induction heating method, and it is necessary to focus on inspecting the copper induction coil surrounding the furnace body 1 to check whether there is wear or breakage, and to ensure that it can generate an alternating magnetic field through the principle of electromagnetic induction after the alternating current is connected, so that eddy currents are generated inside the metal charge to generate heat, thereby ensuring fast heating speed, high efficiency, and precise temperature control. When inspecting the support mechanism 2, confirm that the movable frame 27 (including the upper support frame 21 and the lower support frame 22, and the lower support frame 22 is provided with a longitudinal support frame 23 and an oblique support frame 24) slides smoothly on the inside of the furnace body 1 without any jamming;

[0043] The supporting electric push rod 26 is installed on the outside of the furnace body 1. Its telescopic function needs to be tested to ensure that it can normally push the movable frame 27 to slide inside the furnace body 1, thereby driving the slag scooping mechanism 3 to adjust its position. The reciprocating sleeve 31, reciprocating slide rod 32, connecting rotating column 33, slag scooping filter cartridge 34 and other components of the slag scooping mechanism 3 are inspected. The reciprocating sleeve 31 is rotatably set on the upper supporting frame 21. Check whether its reciprocating slide groove 311 (symmetrically cross-set) is normal. Ensure that the reversing slide rod 351 and directional slide plate 352 on the slag scooping rotating column 35 can alternately slide with the reciprocating slide groove 311 to drive the reciprocating sleeve 31 to rotate back and forth around the axis.

[0044] Check whether the reciprocating slide 32 slides flexibly in the reciprocating sleeve 31, whether the reciprocating bracket 321 at the upper end rotates with the connecting column 33 normally, and whether the positioning rotating frame 322 at the lower end is smoothly linked with the matching rotating column 363 through the reciprocating fork 365;

[0045] Confirm that the connection between the connecting column 33 and the slag filter cylinder 34 is firm, the slag filter cylinder 34 is a bucket-shaped structure with openings at both ends, the internal slag sliding rod 341 and the trapezoidal cross-section slag filter plate 342 are correctly installed, and check the drive box 41, drive sprocket 44, reversing sprocket 43, adjusting sprocket 421, drive chain 441 and other components of the drive mechanism 4. In the drive box 41, the drive sprocket 44 driven by the motor needs to transmit power to the adjusting sprocket 421, the one-way sprocket 362 and the reversing sprocket 43 in sequence through the drive chain 441 to form a closed-loop transmission path; drive the adjusting sprocket 421 set at the telescopic end of the electric push rod 42 to ensure that it can normally adjust the tension of the drive chain 441 and the length of the transmission path to ensure the normal rotation of the one-way turntable 36, thereby driving the slag rotating column 35 to rotate;

[0046] Check the collection hopper 25 and collection pipe 252 of the collection mechanism 5 to ensure that the collection hopper 25 is installed on the movable frame 27 and its inner diameter is larger than the outer diameter of the lower end of the slag filter cartridge 34. The collection push rod 251 in the collection hopper 25 can properly cooperate with the slag filter plate 342. The collection pipe 252 is connected to the collection hopper 25 and extends out of the furnace body 1. It is tightly connected to an external slag collection device that can generate negative pressure to ensure that the slag can be discharged from the furnace body 1 under the action of negative pressure.

[0047] Check the collecting plate 54 and its related transmission parts, and confirm that the fixed bevel gear 53 on the collecting plate 54 (arc-shaped structure) is reliably connected to the collecting rotating column 52, the collecting rotating column 51 and other components rotatably arranged on the movable frame 27, and that each bevel gear is engaged normally and rotates flexibly.

[0048] Afterwards, according to the smelting requirements, corresponding non-ferrous metals (such as aluminum, copper) or special alloys and other metal charges are prepared to ensure that the quality of the raw materials meets the process requirements and no impurities are mixed in. After the raw materials are prepared, they are placed steadily in the furnace body 1. After the metal charge is placed in the furnace body 1, the power supply of the induction heating mechanism 11 is turned on, the appropriate heating parameters are set, and the induction coil is started. At this time, the induction coil generates an alternating magnetic field. In the magnetic field, the metal charge generates an induced electromotive force inside to form eddy currents, which generate heat according to Joule's law to achieve heating of the metal charge;

[0049] Next, according to the distribution of slag, the supporting electric push rod 26 is started. The supporting electric push rod 26 pushes the movable frame 27 to slide along the preset sliding track inside the furnace body 1 through telescopic movement, and the slag scooping mechanism 3 is adjusted to a suitable salvaging position so that the slag scooping filter 34 can salvage and collect slag from different areas of the furnace body 1. The motor of the driving mechanism 4 is started, and the motor drives the driving sprocket 44 to rotate. The driving chain 441 transmits power to the adjusting sprocket 421, the one-way sprocket 362 and the reversing sprocket 43, forming a closed-loop transmission path. The one-way sprocket 362 drives the one-way turntable 36 to rotate, and then drives the slag scooping column 35 to rotate, providing power for the slag scooping mechanism 3.

[0050] When the slag scooping operation is performed, the slag scooping rotating column 35 rotates, and the reversing slide bar 351 and the directional slide plate 352 on it slide alternately into the reciprocating slide groove 311 of the reciprocating sleeve 31, forcing the reciprocating sleeve 31 to reciprocate around the axis, driving the internal reciprocating slide bar 32 to reciprocate around the axis synchronously. At the same time, the 8-shaped one-way slide groove 361 on the one-way turntable 36 and the matching slide, the matching rod slides and the matching slide bar 364 is constrained by the one-way slide groove 361 to swing, and the swing is transmitted to the reciprocating fork 365 through the matching rotating column 363, driving the positioning rotating frame 322 to drive the reciprocating slide bar 32 to reciprocate up and down. The rotation of the sleeve 31 causes the reciprocating slide 32 to swing horizontally. Under the combined effect of the up and down reciprocating motion of the reciprocating slide 32 itself, the connecting column 33 performs complex spatial motion, and finally causes the slag filter cylinder 34 at the lower end of the connecting column 33 to perform an N-shaped trajectory motion in the furnace body 1. The slag filter cylinder 34 is immersed in the surface of the molten pool. Its filter structure allows liquid metal to pass through, and the slag filter plate 342 with a trapezoidal cross-section forms a "wide to narrow" filtering channel in the slag filter cylinder 34. The trapezoidal inclined surface guides the slag to gather toward the center of the slag filter cylinder 34, intercepting the slag in the slag filter cylinder 34 to achieve slag salvage.

[0051] When the slag filter drum 34 is full of slag, the slag filter drum 34 is moved to the top of the collection bucket 25 by the support mechanism 2, so that the lower end of the slag filter drum 34 is inserted into the collection bucket 25. Since the inner diameter of the collection bucket 25 is larger than the outer diameter of the lower end of the slag filter drum 34, the accurate alignment of the two is ensured. As the slag filter drum 34 descends, the collecting push rod 251 in the collection bucket 25 pushes the slag filter plate 342, forcing the slag filter plate 342 to slide up along the slag sliding rod 341. When the slag filter plate 342 enters the wider part of the cross-section of the slag filter drum 34, the trapped slag slides off the trapezoidal cross-section slag filter plate 342 under the action of gravity and falls into the collection bucket 25 through the opening at the lower end of the slag filter drum 34. The slag in the collection bucket 25 is discharged from the furnace body 1 through the collection pipe 252 under the action of the negative pressure generated by the external slag collecting device and enters the external slag collecting device.

[0052] At the same time, when the slag scooping column 35 rotates, the driving bevel gear 353 at one end thereof meshes with the collecting bevel gear 511 at one end of the collecting column 51, driving the collecting column 51 to rotate, and the matching bevel gear 512 at the other end of the collecting column 51 meshes with the collecting bevel gear 521 at one end of the collecting column 52, driving the collecting column 52 to rotate, and the reversing bevel gear 522 at the other end of the collecting column 52 meshes with the fixed bevel gear 53 fixed on the collecting plate 54, forcing the collecting plate 54 to rotate in the opposite direction around the rotation axis. The collecting plate 54 is an arc-shaped structure. During the rotation process, it gathers the scattered slag to the center, and cooperates with the composite movement of the slag filter drum 34 to guide the slag to the collection bucket 25. When the slag filter drum 34 absorbs the slag, the collecting plate 54 rotates to gather the surrounding residue; when the slag filter drum 34 discharges the slag, the collecting plate 54 pushes the new slag to the working area of ​​the slag filter drum 34, forming a continuous slag cleaning cycle;

[0053] During the operation, the temperature in the furnace is monitored in real time to ensure that the induction heating mechanism 11 can accurately control the temperature and prevent the temperature from being too high or too low, which affects the smelting quality and equipment safety. If the temperature is abnormal, the heating parameters are adjusted in time. At the same time, the operation of the support mechanism 2, the slag removal mechanism 3, the drive mechanism 4 and the collection mechanism 5 are observed to check whether each component is operating normally and whether there are any abnormal sounds or vibrations. Focus on whether the movement of the slag removal rotating column 35, the reciprocating sleeve 31, the reciprocating slide rod 32 and other components is smooth, whether the transmission of the drive chain 441 is stable, and whether the collection bucket 25 and the slag removal filter cartridge 34 are working properly. If any abnormality is found, the machine is stopped immediately for inspection and the operation is continued after the fault is eliminated.

[0054] Regularly check the amount of slag collected in the collection hopper 25 and the external slag collection device. When it reaches a certain amount, clean it in time to ensure that the collection system is unobstructed and avoid affecting the normal operation of the equipment due to slag accumulation.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
