Description

Technical Field

[0001] This invention relates to the field of aluminum rod production technology, and in particular to a recycling mechanism for aluminum rod production with a separation function. Background Technology

[0002] Aluminum rods are typically melted in a smelting furnace during production. During the smelting process, a layer of aluminum slag is formed. Currently, the aluminum slag generated in the smelting furnace is usually handled by manual or mechanical slag removal. This involves using slag removal tools to push, gather, and remove the floating slag from the surface of the molten aluminum from the smelting furnace.

[0003] However, traditional slag removal methods mainly target the removal of slag from the surface of molten aluminum. Their function focuses on removing aluminum slag from the smelting furnace and does not have the function of further separating and processing the aluminum slag. Since aluminum slag will carry a certain amount of molten aluminum during its formation, and the molten aluminum is easily coated by oxide film and oxide particles, the aluminum slag that has not been removed from the furnace still contains a lot of recyclable aluminum. If it is directly treated as waste slag, it will result in the waste of aluminum resources. At the same time, in the existing slag removal process, aluminum slag is usually mixed with some molten aluminum and discharged, which requires secondary manual processing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a recycling mechanism for aluminum rod production with a separation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A recycling mechanism for aluminum rod production with separation function includes a furnace body and a separation box located beside the furnace body. The furnace body is equipped with a rotary slag removal mechanism for collecting slag and transferring it to the separation box. The upper part of the separation box is equipped with a main drive group for driving the separation cylinder mechanism to rotate. The separation cylinder mechanism is installed inside the lifting cylinder mechanism, and the separation cylinder mechanism and the lifting cylinder mechanism perform solid-liquid separation of slag. The lifting cylinder mechanism includes a lifting cylinder, a conical bottom, and a pusher head. The lifting cylinder is slidably installed on the inner wall of the separation box through a lifting mechanism connecting pair. The lifting mechanism connecting pair is used to connect with an external lifting drive mechanism to realize the lifting function of the lifting cylinder. Connecting ropes are installed on both sides of the upper end of the lifting cylinder. The connecting ropes are used to control the lifting and lowering of the rotating slag-removing mechanism. The separation cylinder mechanism includes a separation cylinder and a spiral blade. The spiral blade is installed on the outside of the separation cylinder. The separation cylinder is located at the center inside the lifting cylinder. The top of the separation cylinder is connected to the main drive group via a driven shaft. An overflow port is provided on the upper part of the side wall of the separation cylinder. The furnace body is equipped with a rotary slag removal mechanism to automatically collect the floating slag on the surface of the molten aluminum liquid. It works in conjunction with a separation cylinder mechanism and a lifting cylinder mechanism to realize continuous conveying and solid-liquid separation of the floating slag. The reciprocating lifting motion of the lifting cylinder mechanism enables continuous operations such as slag removal and feeding, floating slag separation, and waste slag discharge.

[0006] In addition, the preferred structure is that the rotating slag-removing mechanism includes a drive gear ring, a connecting ring, and a slag-removing frame. The drive gear ring and the connecting ring are rotatably installed on the inner wall of the furnace body. The connecting ring is slidably engaged with the middle of the drive gear ring through a connecting column. The connecting column is fixedly installed on both sides of the slag-removing frame.

[0007] In addition, a preferred structure is that the slag removal frame is provided with an inclined discharge port inside, and a collection trough is provided on one side of the slag removal frame. The collection trough is connected to the inclined discharge port. When the slag removal frame rotates and moves, the slag floating on the surface of the molten aluminum liquid enters the inclined discharge port through the collection trough and is discharged outward along the inclined discharge port.

[0008] In addition, a preferred structure is that the inner wall of the furnace is provided with an inclined flow channel, which is arranged downwards toward the separation box and is used to receive the aluminum-containing slag mixture discharged from the slag removal frame.

[0009] Furthermore, in a preferred configuration, the main drive assembly includes a support base, a motor, a driven shaft, and a drive toothed disc. The support base is fixedly installed on the upper part of the separation box, the motor is installed on one side of the support base, and the drive toothed disc is rotatably installed on the upper part of the separation box. The drive toothed disc is driven to rotate by the motor. The driven shaft and the drive toothed disc form a nested rotatable connection. The upper end of the driven shaft is rotatably installed inside the support base, and the bottom of the driven shaft is connected to the separation cylinder.

[0010] In addition, a preferred structure is that the upper part of the side wall of the lifting cylinder is provided with a liquid inlet two, which is connected to the output end of the inclined flow channel to receive the molten aluminum liquid and slag mixture transported by the inclined flow channel, and a pusher is provided in the middle of the upper end of the lifting cylinder.

[0011] In addition, a preferred structure is that the bottom of the lifting cylinder is provided with a conical bottom in the middle, the bottom side wall of the conical bottom is provided with a liquid inlet, the bottom end of the conical bottom is provided with an outlet, the outlet is connected to the top inlet of the transfer furnace, the transfer furnace is installed at the bottom of the separation box, and the top inlet of the transfer furnace extends through the waste residue outlet to connect with the bottom outlet of the conical bottom.

[0012] Furthermore, in a preferred configuration, the driving toothed disc and the driven toothed disc mounted in the middle of the driven shaft are meshed together. A driving gear is connected to the bottom of the driven toothed disc. The bottom of the driving gear is rotatably connected to the connecting frame. The other side of the connecting frame is rotatably connected to the input gear. The driven toothed disc and the input gear are mounted together on the connecting frame. The input gear is mounted on the input shaft of the transmission box. The output end of the transmission box is used to drive the driving gear ring to rotate.

[0013] In addition, a preferred structure is that connecting ropes are installed on both sides of the upper end of the lifting cylinder. The connecting ropes extend into the furnace body and are connected to the support roller frame. The support roller frame is located below the connecting ring and forms a support cooperation with the connecting ring. When the lifting cylinder moves vertically up and down, the connecting ropes generate a pulling force simultaneously, causing the connecting ropes to drive the support roller frame to rotate, thereby supporting the bottom wall of the connecting ring.

[0014] In addition, a preferred structure is that the bottom outer side of the lifting cylinder has multiple discharge ports, one side of which is slidably fitted with a fixing plate. The fixing plate is fixedly installed on the inner wall of the separation box, and a retaining ring is installed on the upper part of the inner wall of the lifting cylinder.

[0015] The beneficial effects of this invention are as follows: In this invention, a rotary slag-removing mechanism is installed inside the furnace to automatically collect the floating slag on the surface of the molten aluminum liquid. In conjunction with the separation cylinder mechanism and the lifting cylinder mechanism, the floating slag is continuously transported and the solid-liquid separation process is realized. The reciprocating lifting motion of the lifting cylinder mechanism realizes the continuous operation of the whole device, such as slag removal and feeding, floating slag separation and waste slag discharge. This allows the floating slag to enter the separation area while remaining in a molten state, realizing effective recycling and separation functions and ensuring the operating efficiency of the device.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Reference Figure 1-5 A recycling mechanism for aluminum rod production with separation function includes a furnace body 1, a separation box 2 arranged on the side of the furnace body 1, and a rotary slag removal mechanism arranged inside the furnace body 1. The rotary slag removal mechanism is used to collect the slag generated on the surface of the molten aluminum liquid during the aluminum rod production process and transfer the slag containing aluminum liquid to the subsequent separation and processing area.

[0020] The rotating slag-removing mechanism includes a drive gear ring 5, a connecting ring 6, and a slag-removing frame 7. The drive gear ring 5 and the connecting ring 6 are rotatably installed in the groove opened inside the furnace body 1. The connecting ring 6 is slidably engaged with the middle part of the drive gear ring 5 through a connecting post 61. The connecting post 61 is slidably installed in the vertical direction at the corresponding position of the drive gear ring 5. The connecting post 61 is fixedly installed on both sides of the slag-removing frame 7.

[0021] Specifically, the drive gear ring 5 drives the slag removal frame 7 to rotate synchronously through the connecting column 61, so that the slag removal frame 7 moves along the surface of the molten aluminum liquid, thereby collecting the floating slag on the surface of the aluminum liquid.

[0022] Furthermore, the slag removal frame 7 is provided with an inclined discharge port 71, which is arranged along the length of the slag removal frame 7, and its inner bottom surface forms a guide surface that slopes from high to low, so that the molten aluminum liquid and slag mixture entering the slag removal frame 7 flows to the lower area under its own gravity. A collection trough is opened on one side of the slag removal frame 7, which is connected to the inclined discharge port 71. When the slag removal frame 7 rotates and moves, the slag floating on the surface of the molten aluminum liquid enters the interior of the inclined discharge port 71 through the collection trough and is discharged outward along the inclined discharge port 71, so as to realize the continuous collection of slag.

[0023] A guide plate 72 is rotatably installed on one side of the inclined discharge port 71, and the guide plate 72 covers the opening of the inclined discharge port 71 in its natural state.

[0024] Furthermore, the inner wall of the furnace body 1 is provided with an inclined flow channel 11. The inclined flow channel 11 is arranged downwards towards the separation box 2. The inclined flow channel 11 is used to receive the aluminum-containing slag mixture discharged from the slag removal frame 7 and forms a continuous conveying path through the inclined structure.

[0025] In actual operation, after the aluminum material is smelted inside the furnace body 1, oxide slag and inclusions gradually accumulate on the surface of the molten aluminum liquid. The rotating slag removal mechanism is activated to collect the floating aluminum-containing slag, and then transports it to the separation box 2 through the inclined flow channel 11 for separation processing.

[0026] Reference Figure 6-14 The upper part of the separation box 2 is equipped with a main drive group, which is used to drive the separation cylinder mechanism to rotate. The separation cylinder mechanism is installed inside the lifting cylinder mechanism, and through the rotational cooperation between the separation cylinder mechanism and the lifting cylinder mechanism, the aluminum-containing slag mixture entering the separation box 2 is subjected to solid-liquid separation treatment.

[0027] Among them, the bottom of the separation box 2 is equipped with a waste slag discharge port 4 and a transfer furnace 10.

[0028] The main drive assembly includes a support base 3, a motor 31, a driven shaft 311, and a drive tooth disc 32. The support base 3 is fixedly installed on the upper part of the separation box 2, the motor 31 is installed on one side of the support base 3, and the drive tooth disc 32 is rotatably installed on the upper part of the separation box 2. The drive tooth disc 32 is driven to rotate by the motor 31.

[0029] Specifically, the driven shaft 311 and the drive tooth disc 32 form a nested rotatable connection. The upper end of the driven shaft 311 is rotatably installed inside the support base 3, and is supported and limited by the support base 3. The bottom end of the driven shaft 311 extends into the separation box 2 and is connected to the lower separation cylinder mechanism.

[0030] The bottom of the drive toothed disc 32 is provided with a toothed disc 1, which is meshed with the driven toothed disc 13 installed in the middle of the driven shaft 311. The bottom of the driven toothed disc 13 is connected to a drive gear 131, the bottom of the drive gear 131 is rotatably connected to the connecting frame 21, and the other side of the connecting frame 21 is rotatably connected to the input gear 121. Therefore, the driven toothed disc 13 and the input gear 121 are mounted together on the connecting frame 21.

[0031] Furthermore, the separation cylinder mechanism includes a separation cylinder 9 and a spiral blade 92. The spiral blade 92 is installed on the outside of the separation cylinder 9. The separation cylinder 9 is located at the center inside the lifting cylinder 8. The top of the separation cylinder 9 is drivenly connected to the driven shaft 311. An overflow port 91 is opened on the upper part of the side wall of the separation cylinder 9. The overflow port 91 is used to maintain the solid-liquid ratio of the molten liquid and maintain the solution and temperature required for the existence of slag. Furthermore, the lifting cylinder mechanism includes a lifting cylinder 8, a conical bottom 81, and a pusher head 82. The lifting cylinder 8 is slidably installed on the inner wall of the separation box 2 through a lifting mechanism connecting pair 19. The lifting mechanism connecting pair 19 is used to connect with an external lifting drive mechanism to realize the vertical movement of the lifting cylinder 8 relative to the separation box 2.

[0032] The external lifting drive mechanism can be any one of a hydraulic lifting mechanism, an electric push rod mechanism, a cross linkage lifting mechanism, or a screw lifting mechanism. Those skilled in the art can select one according to the actual use environment. The purpose is to drive the lifting mechanism connecting pair 19 to perform a single reciprocating lifting function. Its specific driving principle belongs to the prior art and will not be described in detail here.

[0033] Next, an inlet 20 is provided on the upper side wall of the lifting cylinder 8. The inlet 20 is connected to the output end of the inclined flow channel 11 to receive the molten aluminum liquid and slag mixture transported by the inclined flow channel 11 and allow it to enter the interior of the lifting cylinder 8.

[0034] In addition, a pusher head 82 is provided at the middle of the upper end of the lifting cylinder 8. The pusher head 82 and the bottom end of the connecting frame 21 form a sliding contact engagement. The pusher head 82 is used to push the connecting frame 21 to move.

[0035] Connecting ropes 14 are installed on both sides of the upper end of the lifting cylinder 8. The connecting ropes 14 extend into the furnace body 1 and are connected to the roller support frame 18. The roller support frame 18 is located below the connecting ring 6 and forms a support cooperation with the connecting ring 6. Under normal working conditions, the roller support frame 18 is embedded in the corresponding groove inside the furnace body 1, and one end of the roller support frame 18 is connected to the connecting rope 14.

[0036] The connecting rope 14 is arranged along the channel between the furnace body 1 and the separation box 2, and passes through the side wall of the furnace body 1 and enters the interior of the separation box 2. The other end of the connecting rope 14 is connected to the lifting cylinder 8.

[0037] When the lifting cylinder 8 moves vertically, the connecting rope 14 pulls synchronously, causing the connecting rope 14 to drive the support roller frame 18 to rotate, thereby pushing the connecting ring 6 and the slag removal frame 7 to their respective height positions.

[0038] Furthermore, the connecting rope 14 forms a sliding friction contact with the furnace body 1 and the separation box 2. Therefore, the connecting rope 14 can be any one of a metal wire rope or a high-temperature resistant composite fiber rope with good high-temperature resistance and wear resistance. At the same time, a wear-resistant and high-temperature resistant sliding bushing or guide sleeve structure is set in the contact area between the connecting rope 14 and the furnace body 1 and the separation box 2, in order to ensure reasonable friction loss during the reciprocating motion of the connecting rope 14.

[0039] In addition, a conical bottom 81 is provided at the middle of the bottom end of the lifting cylinder 8. The conical bottom 81 has a top-inward contraction structure, and a concentrated channel is formed inside to guide the flow of molten aluminum liquid.

[0040] Next, a liquid inlet 83 is provided on the bottom side wall of the conical bottom 81. The liquid inlet 83 is used to guide the molten aluminum liquid that has entered the lifting cylinder 8 into the conical bottom 81. An outlet is provided at the bottom end of the conical bottom 81. The outlet is connected to the top inlet of the transfer furnace 10. The transfer furnace 10 is installed at the bottom of the separation box 2, and the top inlet of the transfer furnace 10 extends through the waste discharge outlet 4, which is used to connect to the bottom outlet of the conical bottom 81. The transfer furnace 10 is connected to the interior of the separation box 2 via a valve body.

[0041] In addition, the bottom of the lifting cylinder 8 is provided with multiple discharge ports 84. One side of the discharge port 84 is in sliding fit with the fixing plate 15. The fixing plate 15 is fixedly installed on the inner wall of the separation box 2. The fixing plate 15 and the discharge port 84 constitute a material flow port.

[0042] In addition, a retaining ring 16 is installed on the upper part of the inner wall of the lifting cylinder 8. The retaining ring 16 and the side wall of the separation cylinder 9 form a squeezing contact fit. When the retaining ring 16 contacts the separation cylinder 9, it is used to reduce the flow of molten liquid and prevent molten slag from falling.

[0043] Reference Figure 13The driven toothed disc 13 is fixedly connected to the bottom of the driven toothed disc 13. The driven toothed disc 13 is slidably mounted on the driven shaft 311 by the limiting key block 17. The upper end of the driven toothed disc 13 is correspondingly set with the driving toothed disc 32, and the two opposite ends are respectively provided with toothed disc structures that mesh with each other.

[0044] The drive gear 131 is meshed with the input gear 121 on one side.

[0045] Furthermore, a transmission box 12 is provided on one side inside the separation box 2. The input shaft end of the transmission box 12 is slidably equipped with an input gear 121 through a keyway structure. In addition, the output end of the transmission box 12 is connected to the drive gear ring 5 through a gear mechanism, so that the slag removal frame 7 can be driven to rotate synchronously during the rotation of the separation cylinder 9, thereby realizing the synchronous operation between the collection of surface slag of molten liquid and subsequent separation processing.

[0046] Among them, a limit key block 17 structure is provided between the input gear 121 and the transmission box 12, so that the input gear 121 can adapt to the vertical displacement changes generated by the lifting cylinder 8 while maintaining power transmission.

[0047] Specifically, when the lifting cylinder 8 moves upward, the pusher 82 on the lifting cylinder 8 pushes the connecting frame 21 to drive the driven toothed disc 13 to move synchronously, so that the driven toothed disc 13 gradually approaches the driving toothed disc 32 until it forms a hard engagement connection with the driving toothed disc 32. When the lifting cylinder 8 descends, the driven toothed disc 13 disengages from the driving toothed disc 32, thereby cutting off the power transmission.

[0048] In this embodiment, after the furnace body 1 produces aluminum rods and generates a slag layer, the motor 31 is started to drive the drive toothed disc 32 to rotate. At this time, the drive toothed disc 32 and the driven toothed disc 13 are in a meshing transmission state, and the power is transmitted to the driven shaft 311 and the separation cylinder 9 rotates synchronously.

[0049] At the same time, the drive gear 131 at the bottom of the driven tooth insert 13 rotates synchronously and drives the input gear 121 to rotate. The input gear 121 transmits power to the transmission box 12, and then the transmission box 12 outputs power to the drive gear ring 5, so that the drive gear ring 5 drives the connecting ring 6 and the slag removal frame 7 to rotate slowly along the surface of the molten aluminum liquid.

[0050] During the rotation of the slag removal frame 7, the slag on the surface of the molten aluminum enters the interior of the slag removal frame 7 through the collection tank.

[0051] After one slag removal process is completed, a separation operation is required. Therefore, both the separation cylinder 9 and the slag removal frame 7 need to stop rotating. Specifically: The external lifting drive mechanism drives the lifting cylinder 8 to descend. At this time, the lifting cylinder 8 drives the push head 82 to move synchronously, causing the driven toothed disc 13 to gradually disengage from the driving toothed disc 32, thus interrupting the power transmission.

[0052] As the lifting cylinder 8 continues to descend, relative displacement occurs between the lifting cylinder 8 and the connecting rope 14. The connecting rope 14 drives the support roller 18 at the other end to move upward. The support roller 18 pushes the connecting ring 6 and the slag removal frame 7 to rise synchronously, causing the slag removal frame 7 to move to the position corresponding to the liquid inlet 20. At this time, the guide plate 72 is no longer constrained by the wall of the furnace body 1 and opens on its own, allowing the aluminum-containing slag mixture collected inside the slag removal frame 7 to enter the interior of the lifting cylinder 8.

[0053] After entering the lifting cylinder 8, the molten mixture is first temporarily stored in the processing area formed by the lifting cylinder 8 and the separation cylinder 9. A large amount of molten aluminum liquid enters the interior of the separation cylinder 9 through the overflow port 91 and is transferred to the transfer furnace 10 by the conical bottom 81.

[0054] During this process, the retaining ring 16 at the top of the lifting cylinder 8 forms a limiting fit with the separation cylinder 9, so that the material remains relatively stable during the descent of the lifting cylinder 8, avoiding the rapid loss of a large amount of molten liquid and ensuring the continuous progress of the subsequent separation process.

[0055] After the separation time reaches the set requirement, the external lifting drive mechanism drives the lifting cylinder 8 to reset and rise. The lifting cylinder 8 drives the driven toothed disc 13 to re-engage with the driving toothed disc 32, so that the power system can resume transmission.

[0056] At the same time, during the ascent of the lifting cylinder 8, the connecting frame 21 drives the input gear 121 to return to its working position, causing the drive gear 131 to drive the input gear 121 to rotate again, and through the transmission box 12 to drive the drive gear ring 5 to rotate, so that the slag removal frame 7 continues to perform the next round of slag removal.

[0057] During the lifting and resetting process of the lifting cylinder 8, the relative position between the separating cylinder 9 and the lifting cylinder 8 changes, and the retaining ring 16 and the separating cylinder 9 form a periodic opening and closing effect, thereby controlling the flow state of molten aluminum inside the separating cylinder 9. Specifically, during slag discharge, there is an assembly gap between the retaining ring 16 and the separating cylinder 9, and the retaining ring 16 is located at the position of the spiral blade 92. During the slag feeding process, the lifting cylinder 8 descends, causing the retaining ring 16 to connect with the side wall of the separating cylinder 9, forming a small gap to block the molten slag.

[0058] When the separator 9 resumes rotation, the spiral blades 92 on its outer side rotate synchronously, causing the molten mixture inside the separator 9 to flow in a spiral pattern. Because the top of the conical bottom 81 and the bottom of the separator 9 form mutually cooperating extrusion zones, the molten mixture is subjected to axial extrusion force and circumferential shearing during rotation, causing relative movement between the molten slag particles inside, thereby accelerating the separation between the molten slag and the aluminum liquid.

[0059] Specifically, when the spiral blade 92 rotates, it can drive the molten aluminum liquid to generate continuous circulation flow, so that the slag particles are concentrated under the action of centrifugation and disturbance. At the same time, the matching structure of the conical bottom 81 and the bottom of the separation cylinder 9 can restrict the flow direction of the material, so that the molten slag is subjected to periodic compression and release, which promotes the detachment of the molten aluminum liquid attached to the surface of the molten slag and improves the aluminum liquid recovery effect.

[0060] After sufficient separation, when the lifting cylinder 8 descends again to discharge the material, the molten aluminum liquid has already entered the conical bottom 81 through the liquid inlet 83 and flows to the transfer furnace 10 for collection; while the separated solid slag is discharged through the discharge port 84 at the bottom of the lifting cylinder 8 and enters the waste slag discharge port 4 for centralized treatment.

[0061] In practical applications, the fixed plate 15, along with the lifting cylinder 8, periodically blocks and opens the bottom discharge port 84 to store and release aluminum dross.

[0062] Therefore, during the entire separation process, after the slag is discharged, the device first introduces the waste slag into the separation box 2. After the single waste slag introduction is completed, the device is reset to continue to perform the secondary slag discharge operation. Meanwhile, the separation process is carried out simultaneously in the separation box 2. As the device repeatedly takes and discharges slag, the separation box 2 performs the operation of storing, separating, and discharging slag in a cycle, thereby achieving continuous collection of floating slag.

[0063] Through the above process, the device utilizes slag collection, aluminum molten metal separation, and power switching control to enable the floating slag in the furnace body 1 to automatically enter the separation area, and achieves preliminary aluminum liquid recovery and continuous slag discharge through the rotation of the separation cylinder 9 and the action of the spiral blades 92.

[0064] In addition, it should be noted that the motor 31, the external lifting drive mechanism and the gear transmission mechanism inside the transmission box 12 are all conventional power and transmission structures in mechanical equipment. Those skilled in the art can select and configure them according to actual usage needs. The specific structure and control method will not be explained further. Among them, furnace body 1 is the melting furnace body.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
