Technical Field

[0001] This utility model relates to the field of aluminum refining technology, specifically to an aluminum alloy ingot refining and impurity removal device. Background Technology

[0002] Aluminum alloy ingots are components formed by casting molten aluminum. Aluminum alloy ingot refining and impurity removal devices generally use refining agents dispersed on the molten aluminum used to make aluminum alloy ingots. Through physical or chemical reactions, hydrogen, non-metallic inclusions (such as alumina and slag) and trace metallic impurities in the molten aluminum are removed, thereby improving the purity of the molten aluminum and improving the mechanical and processing properties of the alloy.

[0003] The patent document, published under the number CN213357709U, entitled "An Aluminum Alloy Ingot Refining Device," describes a device that uses the linkage of multiple components to vibrate a screen, facilitating the removal of inclusions from the treated molten aluminum with high efficiency.

[0004] However, after the second solenoid valve on the feed port is opened, a large amount of molten aluminum still falls mainly into the center of the screen. Over time, this can easily cause the center of the screen to be damaged before other parts. Furthermore, the existing technology does not make it convenient to remove the screen for regular cleaning and maintenance, which brings many inconveniences in actual use and needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum alloy ingot refining and impurity removal device, which solves the problems existing in the above-mentioned prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an aluminum alloy ingot refining and impurity removal device, including a refining cylinder, the top of the refining cylinder is provided with a cylinder cover, the cylinder cover is provided with a water inlet, a refining agent tank, a nitrogen tank and a stirring motor, the stirring motor is provided with a rotating shaft, and the rotating shaft is provided with a stirring component and a uniform ejection component.

[0007] The bottom of the refining cylinder is provided with a guide cavity, and both sides of the top of the guide cavity are provided with solenoid valves. The bottom of the guide cavity is provided with a discharge port, and a uniform ejection assembly is used to discharge the molten aluminum discharged from the discharge port.

[0008] The refining cylinder has tracks on both sides of its bottom, and supports are installed at the bottom of the tracks. A controller is installed on the supports. Both tracks are connected to a purification component, and the purification component is connected to an electric telescopic rod installed at the bottom of the refining cylinder.

[0009] Preferably, a support bearing is connected between the rotating shaft and the refining cylinder, the stirring assembly includes stirring rods evenly arranged on the rotating shaft, and all stirring rods are located inside the refining cylinder, a stirring cover is provided on the rotating shaft, an annular groove is opened at the bottom of the refining cylinder to contact the stirring cover, and the stirring cover is covered on the support bearing.

[0010] Preferably, the uniform discharge assembly includes a fixed bearing disposed outside the discharge port, the outer wall of the fixed bearing is connected to a collecting cylinder, and the bottom of the outer wall of the collecting cylinder is uniformly provided with through grooves.

[0011] Preferably, the impurity removal component includes a slide cylinder mounted on an electric telescopic rod. The slide cylinder is slidably connected to two tracks. Support blocks are evenly arranged circumferentially on the inner wall of the slide cylinder, and the top of the support blocks contacts a filter plate that is attached to the inner wall of the slide cylinder. The filter plate is located below the collection cylinder. A through hole is opened on the rear side of the slide cylinder below the support block. A connecting pipe is connected to the rear end of the through hole. The bottom of the connecting pipe is slidably inserted into a fixed pipe, which is mounted on a bracket.

[0012] Preferably, the track is provided with bolts for connection to the slide.

[0013] Preferably, the top two sides of the support are provided with baffles, the bottom inner wall of the slide cylinder is provided with top tubes on both sides, and the top of the top tubes are in contact with the filter plate, and the baffles on both sides are respectively attached to the top tubes on both sides.

[0014] This invention provides a refining and impurity removal device for aluminum alloy ingots. Compared with the prior art, it has the following advantages:

[0015] 1. This aluminum alloy ingot refining and impurity removal equipment, by setting a guide cavity, ensures that the solenoid valve is not opposite to the outlet, making it easy for the rotating shaft to pass through the outlet. In this way, when discharging molten aluminum, the stirring motor keeps working, which can drive the collection cylinder to rotate at high speed. This allows the molten aluminum entering the collection cylinder through the outlet to be evenly thrown onto the filter plate through the through groove under the action of centrifugal force. Then, by changing the speed of the stirring motor, the centrifugal force can be changed, so that the range of molten aluminum being thrown out can be varied, thereby avoiding premature damage to a certain part of the filter plate.

[0016] 2. This aluminum alloy ingot refining and impurity removal equipment uses an electric telescopic rod to move the slide cylinder downwards, and the connecting pipe can also move downwards inside the fixed pipe, so that the top of the filter plate is no longer obstructed, making it easier to remove the filter plate for cleaning and maintenance. A stop bar is set up so that the filter plate is blocked when it moves downwards, and then the filter plate stops moving downwards after the slide cylinder moves downwards, so that the filter plate does not need to be manually removed from the slide cylinder, which is more convenient.

[0022] 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.

[0023] See Figures 1-4 This utility model provides the following two technical solutions:

[0024] First embodiment: An aluminum alloy ingot refining and impurity removal device includes a refining cylinder 1, a cylinder cover 2 is provided on the top of the refining cylinder 1, a water inlet 3, a refining agent tank 4, a nitrogen tank 5 and a stirring motor 6 are provided on the cylinder cover 2, the refining agent tank 4 is used to add refining agent so as to react with molten aluminum for refining, the nitrogen tank 5 is used to transport nitrogen to achieve the purpose of degassing, and the stirring motor 6 is provided with a rotating shaft 7, and the rotating shaft 7 is provided with a stirring component and a uniform ejection component;

[0025] The bottom of the refining cylinder 1 is provided with a guide cavity 8, and both sides of the top of the guide cavity 8 are provided with solenoid valves 9. The bottom of the guide cavity 8 is provided with a discharge port 10, and a uniformly thrown component is used to discharge the molten aluminum discharged from the discharge port 10.

[0026] The bottom of the refining cylinder 1 is provided with rails 11 on both sides, and a support 12 is provided at the bottom of the rails 11. A controller 13 for controlling the electrical components in the document is provided on the support 12. Both sides of the rails 11 are connected to the impurity removal component, and the impurity removal component is connected to the electric telescopic rod 17 provided at the bottom of the refining cylinder 1.

[0027] A support bearing is connected between the rotating shaft 7 and the refining cylinder 1. The stirring assembly includes stirring rods 26 evenly arranged on the rotating shaft 7, and all stirring rods 26 are located inside the refining cylinder 1. A stirring cover 27 is provided on the rotating shaft 7. An annular groove is opened at the bottom of the refining cylinder 1 to contact the stirring cover 27, and the stirring cover 27 is covered on the support bearing. When the stirring motor 6 is working, the rotating shaft 7 drives the stirring rods 26 to rotate, and the stirring cover 27 rotates on the annular groove, which can prevent molten aluminum from contacting the support bearing and causing damage to the support bearing.

[0028] The uniform ejection assembly includes a fixed bearing located outside the outlet 10. The outer wall of the fixed bearing is connected to a collection cylinder 14. The bottom of the outer wall of the collection cylinder 14 is uniformly provided with through grooves 15. After refining is completed, the outlet discharges molten aluminum and impurities into the collection cylinder 14. The molten aluminum and impurities are ejected through the through grooves 15. Since the fixed bearing is located on the upper side, it will not be burned by the molten aluminum.

[0029] The impurity removal assembly includes a slide cylinder 16 mounted on an electric telescopic rod 17. The slide cylinder 16 is slidably connected to two tracks 11. Support blocks 18 are evenly arranged circumferentially on the inner wall of the slide cylinder 16. The top of the support blocks 18 contacts the filter plate 19 attached to the inner wall of the slide cylinder 16, which can support the filter plate 19. The filter plate 19 is located below the collection cylinder 14, which can filter the falling aluminum liquid. A through hole 20 is opened on the rear side of the slide cylinder 16, located below the support block 18, for discharging the filtered aluminum liquid. A connecting pipe 21 is connected to the rear end of the through hole 20. The bottom of the connecting pipe 21 is slidably inserted into a fixed pipe 22. The fixed pipe 22 is mounted on a bracket 12. The vertically slidably inserted connecting pipe 21 will not affect its subsequent lifting and lowering with the slide cylinder 16.

[0030] The track 11 is provided with bolts 23 that connect to the slide cylinder 16, which can fix the slide cylinder 16 during use and prevent only the electric telescopic rod 17 from bearing the force.

[0031] The second implementation differs from the first implementation in that: both sides of the top of the support 12 are provided with baffles 25, and both sides of the bottom inner wall of the slide cylinder 16 are provided with top tubes 24, with the top of the top tubes 24 in contact with the filter plate 19. Contact with the filter plate 19 can prevent the filtered aluminum liquid from entering the top tubes 24 and causing leakage. The baffles 25 on both sides are respectively attached to the top tubes 24 on both sides. In this way, when the slide cylinder 16 moves down, the top tubes 24 move up and down with the baffles 25, and the filter plate 19 can be supported by the baffles 25. Thus, after the slide cylinder 16 moves down, the filter plate 19 is detached from the slide cylinder 16, so that the filter plate 19 does not need to be manually removed from the slide cylinder 16.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] During use, after the aluminum molten material is refined, the solenoid valve 9 is opened and the shaft 7 continues to rotate. At this time, the aluminum molten material and impurities enter the guide cavity 8 and finally enter the collection cylinder 14 through the outlet 10. The aluminum molten material in the collection cylinder 14 can be evenly thrown onto the filter plate 19 through the through groove 15 under the action of centrifugal force. Then, the speed of the stirring motor 6 is changed to change the centrifugal force, so that the range of aluminum molten material thrown out can be varied, thereby avoiding premature damage to a certain part of the filter plate 19. After being filtered by the filter plate 19, the aluminum molten material is discharged through the through hole 20 and finally discharged under the guidance of the connecting pipe 21 and the fixed pipe 22. When it is necessary to remove the filter plate 19 for cleaning and maintenance, the slide cylinder 16 is moved down to separate the filter plate 19 from the slide cylinder 16.
