Description

Technical Field

[0001] This invention relates to the field of aluminum alloy smelting and purification processing technology, and in particular to an integrated control device for online degassing and flow channel distribution of aluminum alloys. Background Technology

[0002] During the smelting and casting process of aluminum alloys, a large amount of hydrogen gas is easily dissolved in the molten aluminum. At the same time, impurities such as alumina inclusions and suspended slag are generated. The presence of hydrogen gas and solid impurities will significantly reduce the density, mechanical properties and corrosion resistance of aluminum alloy castings, resulting in quality defects such as porosity, looseness and cracks in the products, which seriously affects the quality of finished aluminum alloy products. Therefore, degassing and impurity removal of molten aluminum is an indispensable core process in the online production of aluminum alloys.

[0003] Currently, most traditional aluminum alloy degassing equipment and trough distribution equipment on the market are of a separate structure. The equipment has low integration, large footprint, and cumbersome production process. Problems such as aluminum liquid cooling, secondary oxidation, overflow and leakage are prone to occur at the equipment connection points. The degassing operation and the trough distribution operation are controlled independently, and the process parameters cannot be linked and matched. The aluminum liquid flow and pressure of different stations are inconsistent, which can easily lead to uneven distribution and liquid level fluctuations, affecting the casting stability. The supporting control system of the separate equipment is cumbersome, difficult to operate and debug, has high energy consumption, and high maintenance costs. It is difficult to adapt to the needs of large-scale, high-precision continuous casting production of aluminum alloys.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an integrated control device for online degassing and channel distribution of aluminum alloys. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an integrated control device for online degassing and flow channel distribution of aluminum alloys, so as to solve the problems mentioned above in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0007] An integrated control device for online degassing and channel distribution of aluminum alloy includes a sealed degassing box, a tank is fixedly installed inside the sealed degassing box, a degassing mechanism is installed inside the tank, and a channel distribution mechanism is installed at the bottom of the sealed degassing box.

[0008] The degassing mechanism includes a rotating rod, which is vertically arranged inside the tank. The bottom end of the rotating rod is rotatably connected to the bottom of the tank, and the top end of the rotating rod extends to the outside of the sealed degassing box. The rotating rod and the sealed degassing box are rotatably connected by a bearing at their through-connection. Two parallel rotating blocks are arranged inside the tank. The rotating blocks pass through the rotating rod and are fixedly connected to it. An airflow channel is opened inside the rotating rod, and the airflow channel is connected to the internal cavity of the rotating block. Several gas outlet stirring pipes are fixedly installed at the bottom of the rotating block, and the gas outlet stirring pipes are connected to the internal cavity of the rotating block.

[0009] The rotating block is internally fitted with several sliding rods, and a sliding plate is fitted around the outside of the sliding rods. The sliding plate slides in contact with the sliding rods. Several push rods are fixedly connected to the bottom of the sliding plate and extend vertically into the air outlet stirring tube. A disc is fixedly fitted around the outside of the push rod, and several through grooves are formed on the disc and arranged in a ring around the axis of the push rod. The outer wall of the disc slides in contact with the inner wall of the air outlet stirring tube. A plug is fixedly installed at the bottom of the push rod and seals against the bottom opening of the air outlet stirring tube.

[0010] To address the issues of uncontrollable rotation speed, poor mixing uniformity, and high manual labor intensity in the degassing and stirring structure, the degassing mechanism further includes a rotation control component. This component comprises a top shell fixed to the top of the sealed degassing box. A rotating rod passes through the top shell and is connected to it via a bearing. A motor is mounted on the top of the top shell, and a drive shaft is fixedly connected to the motor's output end. One end of the drive shaft is connected to the top of the sealed degassing box via a bearing. A first gear is fixedly sleeved on the outside of the drive shaft, and a second gear is fixedly sleeved on the outside of the rotating rod. The second gear meshes with the first gear.

[0011] To address the issues of traditional degassing ducts being unable to adaptively open and close, and the waste caused by continuous gas delivery, the degassing mechanism further includes a duct opening and closing assembly. This assembly comprises a top frame, a first hydraulic push rod, and a connecting rod. The top frame is fixedly installed on the top end face of the top shell, and the first hydraulic push rod is fixedly assembled on the top of the top frame. The telescopic end of the first hydraulic push rod is rotatably connected to the connecting rod. The connecting rod extends vertically into the airflow channel inside the rotating rod, and is fixedly connected through one of the sliding plates. The bottom end of the connecting rod is fixedly connected to the top surface of the other sliding plate.

[0012] To address the issue of poor sealing performance and easy air leakage in the airflow channel, two sealing rings are embedded and fixed inside the rotating rod. Both sealing rings are sleeved on the outside of the connecting rod, and the inner sidewall of the sealing ring is in a sealing sliding fit with the outer sidewall of the connecting rod.

[0013] To address the issues of easy entanglement of the air intake pipe and unstable air supply during the rotation of the rotating rod, a rotary joint is fixedly mounted on the outer side of the rotating rod, with the rotor end of the rotary joint connected to the airflow channel; an air intake pipe is fixedly connected to the stator end of the rotary joint, extending to the outside of the sealed degassing box and fixedly connected to the sealed degassing box; a base plate is fixedly installed on the outer wall of the sealed degassing box, and an air supply pump is fixedly mounted on the top of the base plate, with the output end of the air supply pump fixedly connected to the air intake end of the air intake pipe.

[0014] In order to solve the problems of low automation and failure to discharge exhaust gas in a timely manner, a controller is fixedly installed on the outer wall of the sealed degassing box; a negative pressure exhaust fan is installed on the top of the sealed degassing box, and the air inlet of the negative pressure exhaust fan is fixedly connected to an exhaust hood, which is arranged on the top of the inner cavity of the sealed degassing box.

[0015] To address the issues of traditional flow channel distribution structures' inability to independently control material across multiple channels and poor sealing during material interruption, the flow channel distribution mechanism includes a main flow channel, several branch flow channels, a second hydraulic push rod, and a third hydraulic push rod. The main flow channel vertically penetrates the bottom of the sealing degassing box and the bottom of the tank body and is fixedly connected to both. A stop ring is fixedly installed on the top inner side of the main flow channel. A second hydraulic push rod is fixedly installed at the bottom of the main flow channel, and the telescopic end of the second hydraulic push rod extends into the interior of the main flow channel and is fixedly connected to a sealing plate. The sealing plate can seal and abut against the stop ring.

[0016] Several branch channels are fixedly arranged in a ring outside the main channel and communicate with the inner cavity of the main channel; a bracket is fixedly assembled on the outside of the main channel and below the branch channels, and a third hydraulic push rod is fixedly installed at the bottom of the bracket. The telescopic end of the third hydraulic push rod vertically penetrates the bracket and is fixedly connected to a partition. The partition extends into the interior of the branch channels and slides in cooperation with the branch channels; a slag discharge pipe for slag discharge is also fixedly connected to the bottom of the main channel.

[0017] In order to solve the problems of large impact and splashing of molten aluminum during feeding, an inlet pipe is fixedly installed through the side wall of the sealed degassing box, and the outlet port of the inlet pipe is set towards the inner side wall of the tank.

[0018] In order to solve the problem of not being able to monitor the aluminum liquid level in real time and the easy occurrence of overflow, a liquid level sensor is installed on one side of the sealed degassing box. The detection end of the liquid level sensor extends into the tank body to detect the aluminum liquid level inside the tank body in real time.

[0019] To address the issue of equipment support, several support columns for supporting the equipment are fixedly installed at the bottom of the sealed degassing box.

[0020] The above technical solution has the following beneficial effects:

[0021] 1. This invention adopts an integrated structure for degassing and flow channel distribution, abandoning the traditional separate equipment layout, greatly reducing the equipment footprint, simplifying the production process, avoiding problems such as aluminum liquid cooling, secondary oxidation, and leakage during the connection of separate equipment, and effectively improving the continuity and stability of online aluminum alloy production.

[0022] 2. This invention features an adaptively openable and closeable jet agitation and degassing structure. The automatic opening and closing of the outlet pipe is achieved through a hydraulic linkage component. It can effectively prevent blockage when in standby mode and simultaneously agitate the air during operation, breaking the inert gas into micron-sized fine bubbles. This significantly improves the uniformity and thoroughness of aluminum liquid degassing and impurity removal, effectively solving the problems of large degassing blind spots, poor degassing effect, and gas waste in traditional equipment, and significantly improving the purification quality of aluminum liquid.

[0023] 3. This invention adopts a gear-driven rotary stirring structure, which is stable in transmission and adjustable in speed, and can be adapted to the degassing requirements of different working conditions. Combined with a rotary joint dynamic-static separation air intake structure, it completely solves the problems of entanglement and leakage in rotary air supply pipes, ensuring that the equipment can operate continuously and stably for a long time, and reducing the equipment failure rate and maintenance costs.

[0024] 4. This invention features a multi-channel, independently controllable flow channel distribution mechanism, which can achieve flexible diversion and feeding in single or multiple channels to meet diverse production needs. It is also equipped with an independent slag discharge structure to facilitate the cleaning of slag and residual liquid. It has a high degree of automation, requires no manual operation, and greatly improves production efficiency. Attached Figure Description

[0039] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] See Figures 1-11 As shown, an integrated control device for online degassing and channel distribution of aluminum alloy according to the present invention includes a sealed degassing box 1, a tank 13 fixedly installed inside the sealed degassing box 1, a degassing mechanism installed inside the tank 13, and a channel distribution mechanism installed at the bottom of the sealed degassing box 1.

[0041] The degassing mechanism includes a rotating rod 19, which is vertically arranged inside the tank body 13. The bottom end of the rotating rod 19 is rotatably connected to the bottom of the tank body 13, and the top end of the rotating rod 19 extends to the outside of the sealed degassing box 1. The rotating rod 19 and the sealed degassing box 1 are rotatably connected by a bearing at their through connection. Two parallel rotating blocks 20 are arranged inside the tank body 13. The rotating blocks 20 pass through the rotating rod 19 and are fixedly connected to the rotating rod 19. An airflow channel 21 is opened inside the rotating rod 19 and is connected to the internal cavity of the rotating block 20. Several gas outlet stirring pipes 26 are fixedly installed at the bottom of the rotating block 20 and are connected to the internal cavity of the rotating block 20.

[0042] The rotating block 20 is internally fitted with several sliding rods 36, and a sliding plate 35 is fitted around the outside of the sliding rods 36. The sliding plate 35 slides with the sliding rods 36. Several push rods 30 are fixedly connected to the bottom of the sliding plate 35. The push rods 30 extend vertically into the interior of the gas outlet stirring pipe 26. A disc 31 is fixedly fitted around the outside of the push rod 30. Several through grooves 32 are provided on the disc 31 and are distributed in a ring around the axis of the push rod 30. The outer wall of the disc 31 slides against the inner wall of the gas outlet stirring pipe 26. A plug 33 is fixedly installed at the bottom of the push rod 30. The plug 33 seals and abuts against the bottom opening of the gas outlet stirring pipe 26.

[0043] Working Principle: During operation, the degassing mechanism serves as the core structure for aluminum liquid purification, enabling precise supply of inert gas and dynamic agitation for degassing. Under normal conditions, the plug 33 tightly seals the bottom opening of the outlet agitator pipe 26, effectively preventing aluminum liquid from backflowing into the pipe and causing blockages and slag accumulation. When degassing is required, the slide plate 35 slides vertically upward along the slide rod 36, causing the push rod 30, disc 31, and plug 33 to move upward simultaneously, releasing the plug 33 from blocking the outlet agitator pipe 26 and fully opening the pipe passage. The inert gas enters the inner cavity of the rotating block 20 through the airflow channel 21 and is ejected from the bottom of the pipe through the inside of the outlet agitator pipe 26 and the through groove 32 of the disc 31. Simultaneously, the rotating rod 19 drives the rotating block 20 and the gas outlet stirring pipe 26 to rotate at high speed, shearing and dispersing the sprayed inert gas, causing the gas to form a large number of tiny bubbles that are evenly dispersed in the molten aluminum inside the tank 13. This fully adsorbs hydrogen and oxide impurities inside the molten aluminum, completing the degassing and purification operation of the molten aluminum. During standby operation, the sliding plate 35 moves down and resets, causing the plug 33 to re-seal the gas outlet stirring pipe 26, preventing molten aluminum and slag from entering the pipeline, ensuring unobstructed pipeline flow, and avoiding standby blockage failures.

[0044] The degassing mechanism further includes a rotation control component, which includes a top shell 6, which is fixedly mounted on the top of the sealed degassing box 1. A rotating rod 19 passes through the top shell 6 and is connected to the top shell 6 via a bearing. A motor 12 is mounted on the top of the top shell 6, and a drive shaft 27 is fixedly connected to the output end of the motor 12. One end of the drive shaft 27 is connected to the top of the sealed degassing box 1 via a bearing. A first gear 28 is fixedly sleeved on the outside of the drive shaft 27, and a second gear 29 is fixedly sleeved on the outside of the rotating rod 19. The second gear 29 meshes with the first gear 28.

[0045] Working Principle: The rotary control component provides stable and adjustable rotary power for degassing and agitation. During operation, the motor 12 starts and outputs torque, driving the transmission shaft 27 to rotate at a constant speed. The transmission shaft 27 synchronously drives the first gear 28 fixed on the outside to rotate. Relying on the gear meshing transmission principle, the first gear 28 drives the second gear 29 to rotate synchronously, thereby driving the rotating rod 19 to rotate as a whole. The speed and start / stop status of the motor 12 can be precisely adjusted through the controller 3, which can flexibly control the rotation speed of the rotating rod 19, the bottom rotating block 20, and the exhaust agitation pipe 26, adapting to different aluminum liquid capacities and different purification precision production conditions. The gear transmission structure has high transmission precision and good operational stability, enabling uniform agitation and avoiding uneven bubble distribution and degassing blind spots caused by speed fluctuations. At the same time, the entire process is fully automated, requiring no manual intervention and significantly reducing the intensity of manual operation. The top shell 6 provides protection and positioning for the overall transmission structure. In conjunction with the bearing connection structure, it can effectively reduce rotational friction resistance and improve the structural operational stability and service life.

[0046] The degassing mechanism also includes an air passage opening and closing assembly, which includes a top frame 7, a first hydraulic push rod 8, and a connecting rod 22. The top frame 7 is fixedly installed on the top end face of the top shell 6, and the first hydraulic push rod 8 is fixedly assembled on the top of the top frame 7. The telescopic end of the first hydraulic push rod 8 is rotatably connected to the connecting rod 22. The connecting rod 22 extends vertically into the airflow channel 21 inside the rotating rod 19. The connecting rod 22 is fixedly connected through one of the sliding plates 35, and the bottom end of the connecting rod 22 is fixedly connected to the top surface of the other sliding plate 35. Two sealing rings 34 are embedded and fixed inside the rotating rod 19. Both sealing rings 34 are sleeved on the outside of the connecting rod 22, and the inner sidewall of the sealing ring 34 is in a sealing sliding fit with the outer sidewall of the connecting rod 22.

[0047] A rotary joint 25 is fixedly mounted on the outside of the rotating rod 19. The rotor end of the rotary joint 25 is connected to the airflow channel 21. An air inlet pipe 23 is fixedly connected to the stator end of the rotary joint 25. The air inlet pipe 23 extends to the outside of the sealed degassing box 1 and is fixedly connected to the sealed degassing box 1. A base plate 4 is fixedly installed on the outer wall of the sealed degassing box 1. An air supply pump 5 is fixedly mounted on the top of the base plate 4. The output end of the air supply pump 5 is fixedly connected to the air inlet end of the air inlet pipe 23.

[0048] Working Principle: The air passage opening and closing assembly realizes automated and adaptive opening and closing control of the air outlet pipe, and works with the air supply structure to achieve stable and tangle-free air supply. The top frame 7 provides fixed support for the first hydraulic push rod 8. During operation, the telescopic end of the first hydraulic push rod 8 extends upward, pulling the connecting rod 22 vertically upward along the airflow channel 21. The connecting rod 22 simultaneously drives the upper and lower sets of sliding plates 35 to slide synchronously along the sliding rod 36, completing the opening action of all air outlet stirring pipes 26 in a coordinated manner, realizing the air passage opening. In standby mode, the first hydraulic push rod 8 retracts, pushing the connecting rod 22 downward, driving the plug 33 to reset and seal the pipe opening, cutting off the air outlet channel, avoiding gas waste due to empty transport, and preventing aluminum liquid backflow. During the relative sliding process between the connecting rod 22 and the rotating rod 19, the sealing ring 34 is always tightly fitted with the outer wall of the connecting rod 22, effectively sealing the gap in the airflow channel 21, preventing gas leakage, and ensuring stable air supply pressure. During gas supply operations, the gas pump 5 starts, delivering inert, pressure-stabilized gas to the inlet pipe 23. The gas is then introduced into the airflow channel 21 via the rotary joint 25. The rotary joint 25 employs a dynamic-static separation structure, with the stator end fixed and the rotor end rotating synchronously with the rotating rod 19. This completely solves the problems of entanglement, twisting, and leakage in the inlet pipe 23 during the high-speed rotation of the rotating rod 19, ensuring continuous and stable gas supply. Simultaneously, the connecting rod 22 and the rotating rod 19 can rotate synchronously without affecting the overall stirring and rotation operation, achieving independent operation of start / stop control and rotation.

[0049] A controller 3 is fixedly installed on the outer wall of the sealed degassing box 1; a negative pressure exhaust fan 9 is assembled on the top of the sealed degassing box 1, and an exhaust fan hood 24 is fixedly connected to the air inlet end of the negative pressure exhaust fan hood 9. The exhaust fan hood 24 is arranged on the top of the inner cavity of the sealed degassing box 1.

[0050] Working Principle: Controller 3, as the core control unit of the equipment, centrally controls all electrical components, including motor 12, first hydraulic push rod 8, second hydraulic push rod 17, third hydraulic push rod 18, air supply pump 5, negative pressure exhaust fan 9, and liquid level sensor 10. This enables fully automated control of the entire process, from degassing and diversion to exhaust and liquid level monitoring, uniformly matching production process parameters and solving the problems of parameter mismatch and cumbersome operation associated with traditional separate equipment. During the degassing process, after the adsorbed hydrogen and slag-laden bubbles rise and burst, hydrogen and trace amounts of dust and other waste gases gather at the top of the sealed degassing box 1. At this time, the negative pressure exhaust fan 9 starts, creating a negative pressure suction force on the cavity inside the box through the exhaust hood 24, quickly and centrally extracting and expelling the waste gas outside the equipment. This prevents waste gas from stagnating inside the box, causing pressure imbalance and gas backflow, while also preventing the accumulation of harmful gases, ensuring a sealed operating environment, and improving the quality of aluminum liquid purification and production safety.

[0051] The flow channel distribution mechanism includes a main flow channel 14, several branch flow channels 15, a second hydraulic push rod 17, and a third hydraulic push rod 18. The main flow channel 14 vertically penetrates the bottom of the sealed degassing box 1 and the bottom of the tank body 13 and is fixedly connected to both. A stop ring 38 is fixedly installed on the top inner side of the main flow channel 14. The second hydraulic push rod 17 is fixedly installed at the bottom of the main flow channel 14. The telescopic end of the second hydraulic push rod 17 extends into the interior of the main flow channel 14 and is fixedly connected to a sealing plate 40. The sealing plate 40 can seal and abut against the stop ring 38.

[0052] Several branch channels 15 are annularly fixed to the outside of the main channel 14 and communicate with the inner cavity of the main channel 14; a bracket 16 is fixedly assembled on the outside of the main channel 14 and below the branch channels 15, a third hydraulic push rod 18 is fixedly installed at the bottom of the bracket 16, the telescopic end of the third hydraulic push rod 18 vertically penetrates the bracket 16 and is fixedly connected to a partition 39, the partition 39 extends into the inside of the branch channels 15 and slides in cooperation with the branch channels 15; a slag discharge pipe 37 for slag discharge is also fixedly connected to the bottom of the main channel 14.

[0053] Working Principle: The flow channel distribution mechanism enables precise diversion, on / off control, and slag cleaning of the purified molten aluminum. Under normal conditions, the second hydraulic push rod 17 extends, pushing the sealing plate 40 to tightly seal against the abutment ring 38, blocking the top channel of the main flow channel 14, and temporarily storing and purifying the molten aluminum in the tank 13. After the molten aluminum is degassed and impurities removed, the controller 3 controls the second hydraulic push rod 17 to retract, causing the sealing plate 40 to move downwards, releasing the blockage of the main flow channel 14, allowing the purified molten aluminum in the tank 13 to flow smoothly into the main flow channel 14. According to production diversion requirements, the third hydraulic push rod 18 can be activated individually or in multiple groups. The telescopic end of the third hydraulic push rod 18 drives the partition plate 39 to slide vertically, opening or closing the corresponding branch flow channel 15 as needed, achieving flexible single-channel and multi-channel diversion and feeding to meet the production needs of different workstations and capacities. The diversion is precise and controllable, effectively avoiding uneven diversion and liquid level fluctuations. When the equipment is shut down or undergoing cleaning and maintenance, all branch channels 15 are closed. Residual molten aluminum and precipitated slag in the main channel 14 can be discharged through the bottom slag discharge pipe 37, eliminating the need for manual slag removal. This automated cleaning method is highly efficient and convenient to maintain. The bracket 16 provides stable support for the third hydraulic push rod 18, ensuring precise sliding alignment of the partition 39 and guaranteeing the sealing and shut-off effects of the flow channel.

[0054] A liquid inlet pipe 11 is fixedly installed through the side wall of the sealed degassing box 1, and the liquid outlet port of the liquid inlet pipe 11 is set towards the inner side wall of the tank body 13.

[0055] Working principle: After external smelting, the molten aluminum is transported to the inside of the tank 13 through the inlet pipe 11. The outlet of the inlet pipe 11 faces the inner wall of the tank 13. This changes the traditional direct-flow inlet method. The molten aluminum flows down along the inner wall of the tank, which can effectively buffer the impact force of the molten aluminum feed and avoid the direct impact of high-speed feed on the surface of the molten aluminum inside the tank 13. This eliminates the problems of molten aluminum splashing and violent fluctuations in the liquid surface. At the same time, it reduces the secondary oxidation inclusions caused by the feed impact, ensuring a stable surface of the molten aluminum inside the tank and providing a stable liquid layer environment for subsequent uniform degassing operations.

[0056] A liquid level sensor 10 is installed on one side of the sealed degassing box 1. The detection end of the liquid level sensor 10 extends into the tank body 13 and is used to detect the liquid level of aluminum liquid inside the tank body 13 in real time.

[0057] Working principle: The liquid level sensor 10 collects the liquid level signal of the aluminum liquid inside the tank 13 in real time and transmits the monitoring data to the controller 3 in real time. When the liquid level is lower than the set threshold, the controller 3 can link the front-end feeding equipment to replenish the material; when the liquid level is higher than the set threshold, it will issue an early warning and stop feeding in time to prevent the aluminum liquid inside the tank 13 from overflowing, the liquid level from affecting the stirring and degassing operation, and at the same time avoid the stirring structure from running idle and the equipment from running without load due to the liquid level being too low. This realizes real-time closed-loop control of the aluminum liquid level and ensures the continuous, stable and safe operation of the equipment.

[0058] The bottom of the sealed degassing box 1 is fixedly equipped with several support columns 2 for supporting the equipment.

[0059] Working principle: Multiple sets of support columns 2 are evenly distributed at the bottom of the sealed degassing box 1, which play a role in stabilizing the overall equipment and bearing the load and buffering. The equipment can be raised as a whole to avoid water, dust and debris from the ground from corroding the bottom structure and flow channel distribution mechanism of the equipment. At the same time, it ensures that the equipment is placed horizontally, effectively reducing the displacement and shaking caused by vibration during the operation of the equipment, improving the stability of the equipment operation, and facilitating the inspection and maintenance of the bottom slag discharge pipe 37 and hydraulic components.
