Description

Technical Field

[0001] This utility model relates to the field of rheological die casting technology, and in particular to an aluminum alloy liquid degassing and refining device. Background Technology

[0002] Rheology pressure casting is a casting process in which molten alloy is poured into a slurry chamber at a temperature above the liquidus to form a semi-solid slurry. Gravity is then used to fill the mold, and pressure is applied by an extrusion mechanism to completely solidify the semi-solid slurry. Its advantage lies in the good rheological properties of the semi-solid slurry, enabling the production of castings with dense internal structures and excellent performance.

[0003] In actual production, after aluminum alloy smelting, the surface of the aluminum alloy has a lot of slag, mainly Al2O3 and other oxide inclusions. These fine inclusions are heavier than the molten aluminum, but after agglomerating, they are lighter and float on the surface, requiring slag removal. After the slag is removed, degassing and refining are carried out. Degassing and refining mainly remove gas and hydrogen. Common methods for degassing rotary refining include degassing refining and powder injection refining. The principle is to introduce inert gas or refining agent into the bottom of the furnace. The refining agent is very light, and the inert gas or refining agent is sprayed from the bottom of the furnace and rises. During the rising process, it carries away hydrogen and slag from the molten aluminum, thereby purifying the molten aluminum. In actual production, slag removal agents are mostly applied manually. Whether it is manually applying slag removal agents or adding materials, operators need to be in close contact with the holding furnace, which poses a risk of burns.

[0004] Furthermore, existing technologies, such as the aluminum alloy liquid degassing equipment disclosed in Chinese Patent No. CN 221566271 U, although employing a stirring unit and a nitrogen supply unit for aluminum alloy liquid degassing, cannot treat the slag generated during the degassing process, thus affecting the refining effect. Moreover, its stirring height is not adjustable, resulting in uneven stirring, which in turn affects the degassing effect. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a rheological die-casting aluminum alloy liquid refining device for degassing and refining molten aluminum before rheological treatment; it solves the problems of low stirring and degassing efficiency and poor refining effect in existing aluminum alloy liquid degassing equipment.

[0006] The technical solution of this utility model is implemented as follows: A refining device for rheological die-casting aluminum alloy liquid includes a vertical column and a cantilever beam. The cantilever beam is slidably mounted on the vertical column and its height on the vertical column is adjusted by a lifting mechanism. A stirring mechanism and a slag-floating mechanism are provided on the cantilever beam. The stirring mechanism includes a stirring drive and a stirrer; the stirring drive drives the stirrer to rotate via a first transmission mechanism. The slag-floating mechanism includes a slag-floating drive and a slag-floating baffle; the slag-floating drive drives the slag-floating baffle to move up and down via a second transmission mechanism. This utility model, by simultaneously setting a stirring mechanism and a slag-floating mechanism on the cantilever beam, can clean slag while stirring. Stirring promotes the floating of inclusions, and the slag-floating mechanism cleans in real time, preventing slag from being re-entered into the melt and improving the continuity of refining. Furthermore, the height of the cantilever beam is adjustable via the lifting mechanism, enabling real-time adjustment of the stirring height to fully stir the aluminum liquid in the holding furnace and improve degassing refining efficiency.

[0007] Further optimization includes an automatic slag removal agent adding mechanism on the cantilever beam. This mechanism comprises a hopper mounted on the cantilever beam, with a miniature screw conveyor at the hopper's outlet. The outlet of the miniature screw conveyor is connected to a discharge pipe, and the miniature screw conveyor is connected to a discharge servo motor mounted on the cantilever beam. By setting the rotation speed and number of revolutions of the discharge servo motor, the amount of slag removal agent conveyed forward by the screw conveyor is controlled, achieving automatic feeding and avoiding the risks associated with manual feeding; moreover, the feeding is more precise.

[0008] Further optimization reveals that the lifting mechanism includes a U-shaped connecting plate seat fixedly connected to the cantilever beam and a chain lifting mechanism mounted on a vertical column. The U-shaped connecting plate seat is connected to the chain of the chain lifting mechanism. A slider is provided on the inner wall of the U-shaped connecting plate seat, and a vertically mounted heavy-duty guide rail is fixed to the side wall of the vertical column. The slider and the heavy-duty guide rail slide against each other. Using a material bar lifting mechanism to drive the cantilever beam up and down results in smoother operation.

[0009] Further optimization reveals that the chain lifting mechanism includes a first motor, a sprocket, and a chain. A vertically positioned guide groove is formed on the vertical column, with the sprocket positioned at both ends of the guide groove. The chain engages with the sprocket, and the first motor is connected to the lower sprocket via a drive system. The advantages of using a chain to lift the cantilever beam are: the rigid meshing of the chain eliminates the risk of slippage; and the height of the stirring mechanism and the scum-flying mechanism can be flexibly adjusted.

[0010] Further optimized, the vertical column is equipped with an adjustable clamp, and the clamp has a limit switch. The U-shaped connecting plate base has a trigger rod corresponding to the limit switch. The output end of the first motor is connected to a reduction motor, and the output end of the reduction motor has a driving sprocket. The axle of the lower sprocket has a driven sprocket, and the driving sprocket is connected to the driven sprocket through a transmission chain. The displacement distance of the cantilever beam is limited by adjusting the vertical position of the limit switch to avoid interference.

[0011] In a further optimized configuration, the scum drive includes a second motor, a guide rail groove fixedly mounted on the cantilever beam, a guide plate slidably mounted within the guide rail groove, and a scum baffle fixed to the guide plate. The second motor drives the guide plate to move up and down along the guide rail groove via a second transmission mechanism. The up-and-down movement of the guide plate achieves the up-and-down movement of the scum baffle, enabling dynamic interception and preventing scum backflow.

[0012] In a further preferred embodiment, the second transmission mechanism includes a gear shaft rotatably mounted on one side of the cantilever beam. One end of the gear shaft has a gear, and the other end has a driven pulley. A vertically arranged rack is mounted on the guide plate, with the rack corresponding to a slot in the guide rail groove. The gear meshes with the rack. The output shaft of the second motor has a driving pulley, which is connected to the driven pulley via a belt. The gear and rack mechanism drive the scum baffle to move smoothly up and down, adapting to different liquid levels.

[0013] In a further preferred embodiment, the stirring drive includes a stirring motor, and the stirrer includes a stirring rod and a stirring head. The stirring head is fixed to the bottom of the stirring rod, and the upper part of the stirring rod is rotatably connected to the cantilever beam. The stirring motor drives the stirring rod to rotate through a first transmission mechanism. The stirring head can move up and down under the action of the cantilever beam, enabling stirring at different liquid levels and improving stirring efficiency.

[0014] Further preferably, the first transmission mechanism includes a first sprocket connected to the output shaft of the stirring motor and a second sprocket rotatably mounted on the cantilever beam. The first sprocket and the second sprocket are connected by a first chain drive, and the axle of the second sprocket is connected to the stirring rod. The stirring head is a disc-shaped component with toothed grooves evenly distributed on its outer circumference. The stirring rod is a hollow tube with a ventilation pipe formed inside, which is connected to an argon cylinder. Under the action of the ventilation pipe, the argon cylinder enters the molten aluminum through the stirrer, making full contact with the molten aluminum and improving the degassing efficiency.

[0015] Further optimization involves mounting the vertical column on a movable base, which also houses the control cabinet and argon cylinder. The movable base facilitates rapid movement of the entire device.

[0016] The beneficial effects of this invention are as follows: This invention adopts a composite design that integrates both a stirring mechanism and a slag removal mechanism in a cantilever beam, achieving parallel stirring and slag removal for continuous slag removal; improving stirring and degassing efficiency, reducing process changeover time, and shortening the single refining cycle; moreover, stirring promotes the floating of inclusions, and the slag removal mechanism cleans them in real time, preventing slag from being re-entered into the melt and improving refining continuity. Stirring ensures uniform melt composition, while slag removal prevents local enrichment, making it particularly suitable for the production of high-alloy aluminum materials; and significantly reducing the product defect rate.

[0017] This invention employs an automatically lifting slag-removing mechanism. The slag baffle can move independently up and down to dynamically intercept slag, preventing slag backflow. Combined with a stirrer, it can thoroughly stir aluminum liquid at different heights, further improving degassing efficiency. Furthermore, the cantilever beam of this invention is equipped with an automatic slag-removing agent addition mechanism. By setting the speed and number of rotations of the servo motor, the amount of slag-removing agent conveyed forward by the screw conveyor is controlled, achieving precise automatic feeding and eliminating the need for manual feeding. Moreover, the slag-removing agent is evenly dispersed in the stirring vortex, preventing localized component segregation. In this embodiment, the cantilever beam integrates stirring, slag removal, and feeding into a compact structure with integrated processes, reducing process changeover time and losses. This makes aluminum refining technology more unmanned, highly purified, and energy-efficient, further improving the degassing and refining effect of rheological die-casting aluminum alloy liquid.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, such as Figure 1As shown, a refining device for rheological die-casting aluminum alloy liquid includes a vertical column 1 and a cantilever beam 2. In actual use, the vertical column 1 can be set on a movable base 8. The movable base is equipped with wheels or an existing mobile trolley to facilitate the rapid movement of the entire device. The movable base 8 also houses a control cabinet 10 and an argon cylinder 7. The control cabinet is the control center of the entire device, controlling the lifting mechanism 3, the stirring mechanism 4, the slag mechanism 5, and automatic feeding, etc. It should be noted that this utility model improves the equipment components and does not involve improvements to the circuit or control program. This utility model only controls the operation and shutdown of various electronic components through a PLC control system. Since the PLC control system is a mature automatic control system in industry, the circuit and control program content will not be described in detail in this utility model. In this invention, the cantilever beam 2 is slidably mounted on the vertical column 1, and its height on the vertical column 1 is adjusted by the lifting mechanism 3. That is, under the action of the lifting mechanism, the cantilever beam can move relative to the vertical column, thereby adjusting its height and consequently adjusting the height of the stirring mechanism 4 and the slag removal mechanism 5. The cantilever beam 2 is equipped with the stirring mechanism 4 and the slag removal mechanism 5; these two mechanisms are integrated on the cantilever beam, allowing stirring and slag removal to proceed in parallel and synchronously, thus improving refining efficiency.

[0025] Specifically, the stirring mechanism 4 includes a stirring drive and a stirrer. The stirrer extends into the holding furnace through the insulation cover 11. The stirring drive drives the stirrer to rotate via a first transmission mechanism, stirring and degassing the molten aluminum in the holding furnace. The slag mechanism 5 includes a slag drive and a slag baffle 51. The slag baffle 51 extends into the holding furnace through the insulation cover 11. The slag drive drives the slag baffle to move up and down via a second transmission mechanism. The slag baffle can move up and down independently to dynamically intercept slag and prevent slag backflow. The stirrer and slag baffle work together to promote the floating of inclusions, and the slag mechanism cleans them in time, preventing slag from being re-entered into the melt and improving refining continuity. The rotation of the stirrer will cause the molten aluminum to form a surface vortex, which can easily re-enter the newly floated oxide slag into the melt. The up-and-down moving baffle can cut into the edge of the vortex in real time, physically blocking the slag backflow path and reducing slag inclusion defects.

[0026] In this preferred embodiment, the cantilever beam 2 is further equipped with an automatic slag removal agent adding mechanism 6 for automatically adding slag removal agent into the holding furnace. Specifically, the automatic slag removal agent adding mechanism 6 includes a hopper 61 mounted on the cantilever beam 2. The hopper is fixed to the cantilever beam by a triangular brace and moves up and down with the cantilever beam. A miniature screw conveyor 62 is provided at the outlet of the hopper 61. The outlet of the miniature screw conveyor 62 is connected to a discharge pipe 63, which passes through the insulation cover 11 and extends into the holding furnace. The miniature screw conveyor 62 is connected to a discharge servo motor 64 mounted on the cantilever beam 2. The discharge servo motor is fixed to the cantilever beam by a plate. By setting the speed and number of rotations of the servo motor, the amount of slag removal agent conveyed forward by the screw conveyor is controlled, achieving precise automatic feeding; avoiding manual feeding; and uniformly dispersing the slag removal agent in the stirring vortex, avoiding local component segregation. In this embodiment, the cantilever beam integrates stirring, slag removal, and feeding into one compact structure and process integration, reducing process switching time and losses, and enabling unmanned, high-purity, and energy-saving aluminum refining technology.

[0027] Example 2, as Figure 4 As shown, a rheological die-casting aluminum alloy liquid refining device is presented in this embodiment, which is a further optimization based on Embodiment 1. In this embodiment, the lifting mechanism 3 includes a U-shaped connecting plate seat 31 fixedly connected to the cantilever beam 2 and a chain lifting mechanism set on the vertical column 1. The U-shaped connecting plate seat 31 is connected to the chain of the chain lifting mechanism and moves synchronously up and down with the chain to realize the height adjustment of the cantilever beam. In this embodiment, sliders 32 are provided on both inner walls of the U-shaped connecting plate seat 31, and vertically arranged heavy-duty guide rails 33 are fixed on both sides of the vertical column 1. The sliders 32 and the heavy-duty guide rails 33 slide in cooperation, so as to realize the smooth sliding of the U-shaped connecting plate seat relative to the vertical column.

[0028] In this embodiment, the chain lifting mechanism includes a first motor 34, a sprocket 35, and a chain 36. A vertically positioned guide groove 37 is provided on the vertical column 1. The sprocket 35 is located at both ends of the guide groove 37, and the chain engages with the sprocket 35, also situated within the guide groove 37. The first motor 34 is connected to the lower sprocket 35 via a transmission chain. Specifically, a reduction motor 311 is connected to the output end of the first motor 34. A drive sprocket 312 is located at the output end of the reduction motor 311, and a driven sprocket 313 is located on the axle of the lower sprocket 35. The drive sprocket 312 is connected to the driven sprocket 313 via a transmission chain 314. The reduction motor drives the sprocket to rotate via the transmission chain, thereby rotating the chain within the guide groove and driving the cantilever beam to rise and fall. The two sets of chain drives achieve smooth movement of the cantilever beam, preventing uneven loading that could cause the cantilever beam to jam. Furthermore, the rigid meshing of the chains reduces the risk of slippage and increases resistance to instantaneous impacts.

[0029] In this preferred embodiment, the vertical column 1 is equipped with an adjustable clamp 38. The clamp 38 is fixed to the column by screws and its position can be adjusted arbitrarily according to actual needs. The clamp 38 is equipped with a limit switch 39, and the U-shaped connecting plate base 31 is equipped with a trigger rod 310 corresponding to the limit switch 39. One clamp corresponds to one limit switch, and the number of clamps can be set to two or more as needed. The vertical displacement of the cantilever beam is limited by adjusting the vertical position of the limit switch, and the upper and lower limit positions can also be set to avoid interference during the operation of the U-shaped connecting plate base 31.

[0030] Example 3, as Figure 2 As shown, a rheological die-casting aluminum alloy liquid refining device is presented. This embodiment is a further optimization based on Embodiment 1 or 2. In this embodiment, the slag drive includes a second motor 52, and a guide rail groove 53 is fixedly provided on the cantilever beam 2. The guide rail groove is fixed to the side wall of the cantilever beam and is vertically arranged. A guide plate 54 is slidably provided in the guide rail groove 53, and a slag baffle 51 is fixed on the guide plate 54. The second motor 52 drives the guide plate 54 to move up and down along the guide rail groove 53 through a second transmission mechanism, thereby realizing the up and down movement of the slag baffle 51. The slag baffle divides the surface of the melt into a "stirring zone" and a "clarification zone", forcing the slag to gather and improving the slag removal efficiency. The slag baffle 51 is a high-temperature resistant baffle. During the process of the agitator stirring the molten aluminum, the slag hits the baffle and stops rotating, then floats to the surface, playing a role in purifying the molten aluminum.

[0031] Specifically, in this embodiment, the second transmission mechanism includes a gear shaft 55 rotatably mounted on one side of the cantilever beam 2. The gear shaft is connected to the cantilever beam via a bearing seat with bearings, enabling its rotation. One end of the gear shaft 55 has a gear 56, and the other end has a driven pulley 59. A vertically arranged rack 57 is fixed on the guide plate 54, and the rack 57 corresponds to a slot in the guide rail groove 53, facilitating meshing between the gear 56 and the rack 57. The output shaft of the second motor 52 has a driving pulley 58, which is connected to the driven pulley 59 via a belt. The second motor transmits power via belt drive, or chain drive. The second motor drives the driven pulley 59 to rotate via the driving pulley 58 and the belt, thereby rotating the gear. The rotation of the gear drives the meshing rack 57 and the guide plate 54 to move relative to the guide rail groove 53, thereby moving the scum baffle 51 up and down to adjust its height.

[0032] In this embodiment, the stirring drive includes a stirring motor 41, which is fixed to the cantilever beam via a motor mount. The stirrer includes a stirring rod 42 and a stirring head 43. The stirring head 43 is fixed to the bottom of the stirring rod 42, and the upper part of the stirring rod 42 is rotatably connected to the cantilever beam 2. The stirring motor 41 drives the stirring rod 42 to rotate via a first transmission mechanism. This allows for uniform stirring of the molten aluminum. Furthermore, in conjunction with the lifting and lowering of the cantilever beam, the stirrer can fully stir molten aluminum at different levels, thereby improving degassing efficiency.

[0033] like Figure 3 As shown, in this embodiment, the first transmission mechanism includes a first sprocket 44 connected to the output shaft of the stirring motor 41 and a second sprocket 45 rotatably mounted on the cantilever beam 2. The first sprocket 44 and the second sprocket 45 are connected by a first chain drive, and the axle of the second sprocket 45 is connected to the stirring rod 42. That is, the stirring motor transmits power to the stirring rod through chain drive, realizing the rotation of the stirring rod. It should be noted that the stirring motor can also use belt drive to transmit power to the stirring rod. In this embodiment, the stirring head 43 is a disc-shaped part with toothed grooves evenly distributed on its outer circumference, forming a petal-like structure, which can improve its efficiency in stirring the molten aluminum. The stirring rod 42 is a hollow tube with a ventilation pipe inside. The ventilation pipe is connected to the argon cylinder 7 through a rotary joint and a pipe. Inert gas is introduced while stirring, which can effectively remove gas from the molten aluminum and improve degassing efficiency.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
