Description

Technical Field

[0001] This invention relates to the field of aluminum alloy refining degassing and static furnace bottom slag discharge technology, specifically to an integrated device for degassing and static furnace bottom slag discharge in an aluminum alloy refining vehicle. Background Technology

[0002] Aluminum alloys are widely used in aerospace, automotive manufacturing, building decoration, and electronics industries due to their excellent properties such as low density, high specific strength, corrosion resistance, and ease of processing. In the aluminum alloy casting process, the purity of the molten aluminum directly determines the mechanical properties, density, and machinability of the final casting. Dissolved hydrogen and suspended solid inclusions in the molten aluminum are the most significant harmful impurities. Currently, the industry generally adopts an independent process of "degassing first, then settling, and then slag removal". First, the aluminum liquid in the settling furnace is degassed by rotating the refining car. After degassing, the aluminum liquid is settling for 15-30 minutes so that the slag inclusions float or sink in layers under the action of gravity. Then, the slag discharge port at the bottom of the furnace is opened manually to discharge the slag. Finally, the surface slag is skimmed off. The aforementioned existing technology has the following obvious defects: the process is fragmented, the production efficiency is low, the degassing and bottom slag discharge are two independent processes, and a 15-30 minute settling and waiting time must be set in between, which results in an excessively long single furnace aluminum liquid processing cycle, low equipment utilization, and seriously restricts the capacity improvement of the production line. Therefore, it is necessary to invent an integrated device for degassing and static bottom slag discharge in aluminum alloy refining vehicles. Summary of the Invention

[0003] Therefore, the present invention provides an integrated device for degassing and static bottom slag discharge in an aluminum alloy refining vehicle to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated device for degassing and static bottom slag discharge in an aluminum alloy refining vehicle, comprising a frame, a housing fixedly connected to the top of the frame, a movable shell slidably disposed inside the housing, a base plate fixedly connected to the top of the movable shell, a hydraulic cylinder fixedly connected between the inner wall of the top of the movable shell and the top of the frame, a dual-axis motor fixedly connected to the top of the base plate, an agitating capture component disposed on the side of the base plate away from the housing, and a conveying component disposed on the side of the base plate closer to the housing, wherein the dual-axis motor drives the agitating capture component to agitate the molten aluminum, and simultaneously drives the conveying component to intermittently convey inert gas into the agitating capture component.

[0005] Furthermore, the agitation-type capture component includes a housing fixedly connected to the top of the base plate, a connecting shell fixedly connected to the top of the housing, a sleeve rotatably connected to the housing and the base plate, an agitation rod fixedly embedded in the sleeve, the bottom end of the agitation rod extending towards the bottom of the base plate, and the top end of the agitation rod located in the connecting shell.

[0006] Furthermore, two connecting rods are fixedly connected to the bottom end of the stirring rod, and both connecting rods and the stirring rod are hollow and interconnected. A nozzle is fixedly connected to the outer end of each of the two connecting rods, and an impeller is fixedly sleeved on the outside of the bottom end of the stirring rod, with the impeller located at the bottom of the connecting rod.

[0007] Furthermore, multiple capture frames are fixedly connected to the outside of the stirring rod, and the multiple capture frames are arranged in a spiral shape. A collection shell is fixedly connected to each of the multiple capture frames. A rotating shaft is rotatably connected to one side of the outer shell. One end of the rotating shaft is fixedly connected to one output end of a dual-axis motor. A bevel gear is fixedly connected to the other end of the rotating shaft. A bevel gear is provided on one side of the bevel gear and meshes with it. The bevel gear is fixedly sleeved on the outside of the sleeve.

[0008] Furthermore, the conveying component includes a connecting plate connected to the base plate. The connecting plate is in sliding contact with one side of the housing. An air pump and a fixing plate are fixedly connected to one side of the connecting plate, and the fixing plate is located on top of the air pump. Two protrusions are fixedly connected to one side of the fixing plate, and a pipe is fixedly embedded on the two protrusions. One end of the pipe is fixedly connected to the air outlet of the air pump, and the other end is connected to the stirring rod through a sealed bearing. The pipe passes through the top of the housing and is fixedly connected thereto.

[0009] Furthermore, the air inlet of the air pump is also fixedly connected to a second pipe, and the second pipe is a flexible hose.

[0010] Furthermore, a reciprocating screw is connected to the other side of the fixed plate. One end of the reciprocating screw is fixedly connected to the other output end of the dual-axis motor. A sliding seat is fitted around the reciprocating screw for use with it. A limit rod is fixedly connected to the top of the base plate. The limit rod passes through the sliding seat and slides in contact with it.

[0011] Furthermore, a movable frame is slidably provided on the fixed plate, the movable frame is fixedly connected to the sliding seat, a pressure rod is fixedly connected to the inner wall of one side of the movable frame, an air cushion is fixedly connected to one side of the fixed plate, the air cushion is fixedly connected to the first pipe, and the air cushion is located inside the movable frame.

[0012] Furthermore, four reinforcing rods are fixedly connected between the housing and the frame.

[0013] The beneficial effects of this invention are: 1. This invention uses a dual-axis motor to synchronously drive the stirring and capturing components and the conveying components. While stirring and degassing the molten aluminum, it actively captures and collects suspended impurities in the molten aluminum using a spirally distributed capturing frame and collection shell.

The single furnace molten aluminum processing cycle is shortened, the equipment utilization rate is improved, and the production line capacity is significantly increased.

[0014] 2. This invention uses the agitation of the impeller to fully suspend the heavy inclusions in the molten aluminum that are originally difficult to settle. Then, the inclusions are captured and collected from all directions by multiple spirally distributed capture frames and collection shells. This can effectively remove heavy inclusions that are difficult to remove by traditional processes, improve the removal rate of inclusions, and greatly improve the purity of the molten aluminum and the mechanical properties of the final casting.

[0015] 3. This invention uses a dual-axis motor to drive a reciprocating lead screw, which in turn drives the sliding seat, moving frame, and pressure rod to reciprocate, periodically compressing the air cushion to achieve intermittent delivery of inert gas. Intermittent gas delivery not only ensures effective degassing but also reduces inert gas consumption, lowers production costs, and achieves cost reduction and efficiency improvement.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Reference Figures 1-10 The present invention provides an integrated device for degassing and slag removal at the bottom of an aluminum alloy refining car, comprising a frame 1, which is welded from steel profiles and has sufficient strength and rigidity to support the weight of the entire device. Four omnidirectional wheels are installed at the bottom of the frame 1 to facilitate free movement of the device within the workshop. One device can serve multiple slag removal furnaces. The top of the frame 1 is fixedly connected to the housing 2. The housing 2 is a rectangular hollow structure and is welded from steel plates. A movable housing 3 is slidably provided inside the housing 2. The outer wall of the movable housing 3 is clearance-fitted with the inner wall of the housing 2 and can slide up and down along the inner wall of the housing 2. The top of the movable housing 3 is fixedly connected to the base plate 4. The base plate 4 is a horizontally set steel plate used to install various functional components. A hydraulic cylinder 5 is fixedly connected between the top inner wall of the movable shell 3 and the top of the frame 1. The cylinder body end of the hydraulic cylinder 5 is fixedly connected to the top of the frame 1, and the piston rod end is fixedly connected to the top inner wall of the movable shell 3. When the hydraulic cylinder 5 is working, it can push the movable shell 3 to slide up and down along the inner wall of the shell 2, thereby driving the base plate 4 and all the components installed on the base plate 4 to move up and down, so as to extend into or out of the molten aluminum. Four reinforcing rods 31 are fixedly connected between the housing 2 and the frame 1. The four reinforcing rods 31 are used to enhance the connection strength between the housing 2 and the frame 1 and improve the overall stability of the device. A dual-axis motor 6 is fixedly connected to the top of the base plate 4. The dual-axis motor 6 has two output ends, which can simultaneously output power to drive two different components to work, realizing the synchronous utilization of power and simplifying the device structure. The bottom plate 4 is provided with an agitation-type capture component on the side away from the shell 2, which is used to agitate and degas the aluminum liquid and simultaneously capture and collect impurities in the aluminum liquid. The bottom plate 4 is provided with a conveying component on the side close to the shell 2, which is used to convey inert gas into the agitation-type capture component. When the dual-shaft motor 6 is working, it can drive the agitation-type capture component and the conveying component to work at the same time, so as to realize the synchronous operation of degassing and impurity capture. Specifically, the agitation-type capture component includes a housing 7 fixedly connected to the top of the base plate 4. The housing 7 is a rectangular hollow structure used to protect the internal transmission components. A connecting shell 8 is fixedly connected to the top of the housing 7. A sleeve 9 is rotatably connected to the housing 7 and the base plate 4. The sleeve 9 is rotatably connected to the housing 7 and the base plate 4 respectively through bearings and can rotate freely. A stirring rod 10 is fixedly embedded on the sleeve 9. The stirring rod 10 is a hollow round rod made of isostatically pressed high-purity graphite. Its surface is uniformly coated with a silicon carbide anti-oxidation coating with a thickness of 50-100μm. This material has a melting point as high as 3652℃, which is much higher than the conventional working temperature of aluminum liquid of 700-750℃. It will not be melted by aluminum liquid during use. At the same time, it does not react chemically with liquid aluminum, has extremely poor wettability, and aluminum liquid will not adhere to its surface, thus not contaminating the aluminum liquid. It also has excellent thermal shock resistance and self-lubricating properties, making it suitable for high-speed rotation operation. The bottom end of the stirring rod 10 extends through the base plate 4 to the bottom of the base plate 4 for insertion into the molten aluminum for operation; the top end of the stirring rod 10 extends through the sleeve 9 and the outer shell 7 to the inside of the connecting shell 8. Two connecting rods 11 are fixedly connected to the bottom end of the stirring rod 10. The two connecting rods 11 are symmetrically distributed on both sides of the stirring rod 10. Both connecting rods 11 and the stirring rod 10 are hollow and interconnected. The connecting rods 11 are made of the same isostatic high-purity graphite material as the stirring rod 10. They are fixedly connected to the stirring rod 10 by threaded connection or high-temperature adhesive to ensure connection strength and airtightness. Both connecting rods 11 are fixedly connected to nozzles 12 at their outer ends. The nozzles 12 are made of isostatic high-purity graphite and have 8-12 nozzle holes with a diameter of 0.5-1mm on their surface. The nozzle holes are radially distributed and can disperse inert gas into uniform micron-sized bubbles, thereby improving degassing efficiency. The inert gas can pass through the channels inside the stirring rod 10 and the connecting rod 11 and finally be ejected from the nozzle holes of the nozzles 12 and enter the aluminum liquid for degassing. An impeller 13 is fixedly sleeved on the bottom of the stirring rod 10. The impeller 13 is located at the bottom of the connecting rod 11 and is made of reaction-sintered silicon carbide ceramic. This material has a melting point of 2730℃, which is much higher than the temperature of aluminum liquid and will not melt. At the same time, it has extremely high wear resistance and impact resistance, and can withstand the strong scouring of aluminum liquid and the impact of slag inclusions. When the impeller 13 rotates with the stirring rod 10, it can generate a strong stirring effect on the aluminum liquid, so that the aluminum liquid forms an up-and-down circulating flow field. This not only makes the inert gas bubbles evenly distributed in the entire aluminum liquid, improving the degassing effect, but also makes the heavy slag inclusions that were originally deposited at the bottom of the furnace fully suspended, which is convenient for subsequent capture and collection. Multiple capture frames 14 are fixedly connected to the outside of the stirring rod 10. The capture frames 14 are spirally distributed on the outer wall of the stirring rod 10. The capture frames 14 are made of isostatic high-purity graphite and are fixedly connected to the stirring rod 10 by a high-temperature adhesive. Each capture frame 14 is fixedly connected to a collection shell 15. The collection shell 15 is made of silicon nitride combined with silicon carbide ceramic. Multiple leakage holes with a diameter of 1-2 mm are evenly opened on the side wall and bottom. The melting point of this material is about 1900℃. It will not be melted by aluminum liquid. It has extremely poor wettability with aluminum liquid and hardly sticks to aluminum. It also has high strength and good toughness and is not easy to crack due to slag inclusion impact. When the capture frame 14 rotates with the stirring rod 10, the impurities suspended in the aluminum liquid will enter the capture frame 14 and fall into the collection shell 15, while the aluminum liquid can flow out through the leakage holes, thereby realizing the separation of impurities from aluminum liquid. A rotating shaft 16 is rotatably connected to one side of the outer casing 7. The rotating shaft 16 is rotatably connected to the outer casing 7 through a bearing. One end of the rotating shaft 16 is fixedly connected to one output end of the dual-axis motor 6, and the other end is fixedly connected to a bevel gear 17. A bevel gear 2 18 is provided on one side of the bevel gear 17 and meshes with it. The bevel gear 2 18 is fixedly sleeved on the outside of the sleeve 9. When the dual-shaft motor 6 is working, one of its output ends drives the rotating shaft 16 to rotate, the rotating shaft 16 drives the bevel gear 17 to rotate, the bevel gear 17 drives the bevel gear 2 18 to rotate, the bevel gear 2 18 drives the sleeve 9 to rotate, and the sleeve 9 ultimately drives the stirring rod 10 to rotate, thereby realizing the functions of stirring, degassing and impurity capture. Specifically, the conveying component includes a connecting plate 19 connected to the base plate 4. The connecting plate 19 is a vertically arranged steel plate, one side of which is fixedly connected to the base plate 4, and the other side is in sliding contact with one side of the housing 2, and can move up and down together with the base plate 4. A gas pump 20 and a fixing plate 21 are fixedly connected to one side of the connecting plate 19. The fixing plate 21 is located on the top of the gas pump 20. Two protrusions 22 are fixedly connected to one side of the fixing plate 21. The two protrusions 22 are distributed vertically and are used to fix the pipe 23. The pipe 23 is fixedly embedded on the two protrusions 22. The pipe 23 is made of 310S high temperature resistant stainless steel and can withstand the transportation of high temperature gas. One end of pipe 23 is fixedly connected to the outlet of air pump 20, and the other end is connected to the top of stirring rod 10 through a high-temperature resistant graphite sealed bearing. Pipe 23 passes through the top of connecting shell 8 and is fixedly connected to connecting shell 8. Pipe 24 is also fixedly connected to the air inlet of air pump 20. Pipe 24 is a high-temperature resistant silicone hose used to connect to an external inert gas source (such as an argon cylinder). A reciprocating screw 25 is connected to the other side of the fixed plate 21. One end of the reciprocating screw 25 is fixedly connected to the other output end of the dual-axis motor 6, and the other end is rotatably connected to the fixed plate 21 through a bearing. A sliding seat 26 is fitted on the outside of the reciprocating screw 25 for use therewith. The sliding seat 26 has a thread inside that matches the reciprocating screw 25. A limiting rod 27 is fixedly connected to the top of the base plate 4. The limiting rod 27 is set parallel to the reciprocating screw 25. The limiting rod 27 passes through the sliding seat 26 and slides in contact with it. The limiting rod 27 is used to restrict the rotation of the sliding seat 26 so that the sliding seat 26 can only move back and forth along the axial direction of the reciprocating screw 25. A movable frame 28 is slidably provided on the fixed plate 21. The movable frame 28 has a U-shaped structure and its bottom is fixedly connected to the top of the sliding seat 26. It can move back and forth with the sliding seat 26. A pressure rod 29 is fixedly connected to the inner wall of one side of the movable frame 28. The pressure rod 29 is a horizontally set round rod made of stainless steel. An air cushion 30 is fixedly connected to one side of the fixed plate 21. The air cushion 30 is made of fluororubber and has good high temperature resistance, elasticity and sealing performance. It can work stably for a long time below 150℃. The air cushion 30 is fixedly connected to the pipe 23 and is located inside the moving frame 28, directly opposite the pressure rod 29. When the dual-axis motor 6 is working, its other output end drives the reciprocating screw 25 to rotate. Under the restriction of the limit rod 27, the reciprocating screw 25 drives the sliding seat 26 to move back and forth along its axis. The sliding seat 26 drives the moving frame 28 and the pressure rod 29 to move back and forth synchronously. When the pressure rod 29 moves towards the air cushion 30, it will squeeze the air cushion 30, causing the air cushion 30 to deform and press the pipe 23, thereby cutting off the flow path of the inert gas. When the pressure rod 29 moves away from the air cushion 30, the air cushion 30 returns to its original shape, the pipe 23 is opened, and the inert gas continues to flow. This cycle repeats to achieve intermittent delivery of inert gas. The working process of this device is as follows: the device is moved to the side of the target stationary furnace by the omnidirectional wheels at the bottom of the frame 1, and the stirring rod 10 is aligned with the center of the furnace door. The hydraulic cylinder 5 is extended, pushing the movable shell 3 to slide upward along the inner wall of the shell 2. The movable shell 3 drives the base plate 4 and all the components installed on the base plate 4 to move upward. Then, the hydraulic cylinder 5 is retracted, pushing the movable shell 3 to slide downward along the inner wall of the shell 2. The movable shell 3 drives the base plate 4 and all the components installed on the base plate 4 to move downward, so that the stirring rod 10, impeller 13, capture frame 14 and collection shell 15 and other components extend from the furnace door into the molten aluminum in the stationary furnace. Then connect pipe 24 to the external argon gas source, open the gas source valve, and adjust the argon gas pressure to 0.2-0.3 MPa; Next, the dual-shaft motor 6 and air pump 20 are started. One output end of the dual-shaft motor 6 drives the sleeve 9 and the stirring rod 10 to rotate through the rotating shaft 16, bevel gear 17 and bevel gear 2 18. When the stirring rod 10 rotates, it drives the impeller 13, connecting rod 11, nozzle 12, capture frame 14 and collection shell 15 to rotate synchronously. The impeller 13 rotates to strongly agitate the molten aluminum, creating a circulating flow field that lifts up the heavy inclusions at the bottom of the furnace and suspends them evenly in the molten aluminum. The gas pump 20 works to send argon gas into the agitator 10 through pipe 24 and pipe 23, and then sprays it out from the nozzle 12 through the channel inside the connecting rod 11, forming a large number of microbubbles. As the microbubbles float in the molten aluminum, they adsorb hydrogen dissolved in the molten aluminum and eventually carry the hydrogen to the surface and break, releasing the hydrogen into the atmosphere, thus achieving the degassing function. As the stirring rod 10 rotates, the spirally distributed multiple capture frames 14 capture impurity particles suspended in the molten aluminum from all directions. After entering the capture frame 14, the impurities fall into the collection shell 15, while the molten aluminum flows out through the leakage hole on the collection shell 15, thereby achieving the capture and collection of impurities. While the dual-axis motor 6 is working, its other output end drives the reciprocating screw 25 to rotate. The reciprocating screw 25 drives the sliding seat 26, the moving frame 28 and the pressure rod 29 to move back and forth along the axial direction, periodically squeezing the air cushion 30, so that the pipeline 23 is periodically opened and closed, realizing the intermittent delivery of argon gas. In this way, while ensuring the degassing effect, the consumption of argon gas is reduced. After the degassing and impurity capture operations are completed (usually 15-20 minutes), turn off the dual-shaft motor 6 and air pump 20, control the hydraulic cylinder 5 to retract, drive the moving shell 3, base plate 4 and all components to move upward, so that the stirring rod 10 and other components extend out of the aluminum liquid and return to the initial position. After the operation is completed, the components should be removed from the aluminum liquid immediately to avoid prolonged exposure to high temperature air, which may cause the graphite components to oxidize and burn. After the collection shell 15 has cooled to room temperature, clean the impurities in the collection shell 15 for use in the next operation. Finally, it is readily apparent that all content not described in detail in this specification, except as described above, is prior art known to those skilled in the art.

[0022] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
