Description

Technical Field

[0001] The present invention relates to the technical field of recycled aluminum alloy ingot casting, and in particular to a high-efficiency cooling device for recycled aluminum alloy ingot casting. Background Art

[0002] Recycled aluminum alloy ingots are made primarily from scrap aluminum alloy materials through a process of disassembly, classification, smelting, purification, and alloying. After casting, proper cooling methods are crucial to ensuring the quality and performance of the ingots, as well as the efficiency of subsequent processing.

[0003] At present, water cooling is generally used to cool the cast aluminum ingots, and water cooling can be divided into water immersion cooling and spray water cooling; among them, spray water cooling is to spray water evenly on the surface of the ingot through a nozzle, and the cooling uniformity is relatively good, and the cooling speed can be controlled by adjusting the water spray volume and the spray range; for example, the patent publication number is CN116571697B, which is a high-efficiency cooling device for casting recycled aluminum alloy ingots. Its main technical means is that the mold that has not been completely cooled can be cooled again through the design of a first intelligent robotic arm, a second intelligent robotic arm, a temperature detection system and a return cooling conveyor belt, thereby ensuring the subsequent processing steps and final product quality of the aluminum alloy ingot. After analysis by the applicant, the disadvantage of this technical solution is that the bottom of the aluminum ingot in the above solution is in direct contact with the conveyor belt, which will cause the cooling water to be unable to contact the bottom of the aluminum ingot, resulting in the bottom of the aluminum ingot being unable to be effectively cooled, resulting in problems such as uneven cooling of the entire aluminum ingot, imbalanced internal stress distribution, and even possible quality defects such as cracks and deformation, thereby affecting the casting quality of the aluminum ingot. Summary of the Invention

[0008] As a preferred embodiment of the above technical solution, two groups of guide frames are symmetrically installed in the sealing cover, the two groups of guide frames are located on the inner sides of the two groups of conveyor belts, the rotating shaft passes through the guide frames, two groups of magnets are symmetrically provided on the periphery of the rotating shaft, and two groups of magnetic parts are symmetrically provided at the straight section of the guide frame.

[0012] As a preferred embodiment of the above technical solution, an adjusting piece is installed on the adjusting plate, and the adjusting piece includes a plurality of elastic telescopic rods 2, a plurality of elastic telescopic rods 3 and a bonding plate. One end of the elastic telescopic rods 2 and 3 are hinged to the adjusting plate, and the other ends of the elastic telescopic rods 2 and 3 are hinged to the bonding plate. The bonding plate is bonded to the surface of the aluminum ingot on the placement rack, and the hinges at both ends of the elastic telescopic rods 2 and 3 are elastically rotatably connected, so that when the adjusting piece is in the initial state, the adjusting plate is in a vertical state, and the elastic telescopic rods 2 and 3 are in a horizontal state.

[0013] The beneficial effects of the present invention are: 1.

In the present invention, the cooperation of the elastic telescopic rod 1, the corrugated plate, the connecting plate, the rack and the gear allows the aluminum ingot to move back and forth in the horizontal direction while moving downward and rotating. When the aluminum ingot moves, the originally blocked area can be exposed to the cooling water, thereby further evenly cooling the aluminum ingot and avoiding the impact of uneven cooling on the casting quality of the aluminum ingot. 3. In the present invention, the spray assembly sprays cooling water horizontally, and the generated water vapor moves upward under the action of the exhaust plate, so that the movement directions of the cooling water and water vapor are perpendicular, thereby effectively avoiding contact between the cooling water and the water vapor, effectively preventing the oxides in the water vapor from returning to the surface of the aluminum ingot and affecting the quality of the aluminum ingot. At the same time, it effectively prevents the temperature of the cooling water from rising before cooling the aluminum ingot, thereby avoiding a reduction in the cooling effect of the cooling water; 4. In the present invention, the angle of the nozzle is adjusted in real time by the adjusting member so that the nozzle is always kept perpendicular to the surface of the aluminum ingot. In this way, the sprayed cooling water will be approximately perpendicular to the surface of the aluminum ingot. Since the cooling water will move downward due to its own gravity after being sprayed, it is difficult for the cooling water to move obliquely upward and contact the rising water vapor, which further effectively prevents the oxides in the water vapor from returning to the surface of the aluminum ingot and affecting the quality of the aluminum ingot, and further prevents the cooling effect of the cooling water from being reduced.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] like Figures 1-7 As shown, a high-efficiency cooling device for casting recycled aluminum alloy ingots includes a base 1, a conveying roller 10, a pusher plate 11 and a conveying roller 2 12, and the device also includes: A sealing cover 2 is provided on the base 1, and the conveying roller 10 and the conveying roller 2 12 are symmetrical along the center of the sealing cover 2. A feed hole 21 and a discharge hole 22 are respectively opened on the sealing cover 2, and the push plate 1 11 faces the feed hole 21. A push plate 2 13 is installed in the sealing cover 2, and the push plate 2 13 faces the discharge hole 22; Driving member 3, two sets of driving members 3 are symmetrically installed on the base 1 along the sealing cover 2, the output end of the driving member 3 extends into the sealing cover 2 and is provided with a turntable 31, and the turntable 31 is also rotatably installed on the inner wall of the sealing cover 2, and the outer periphery of the upper and lower turntables 31 is covered with a conveyor belt 32; The placing rack 4 is provided with several groups of placing racks 4 between the two symmetrical groups of conveyor belts 32. The placing rack 4 includes two rotating shafts 41. The two rotating shafts 41 are respectively rotatably installed on the opposite sides of the two groups of conveyor belts 32. A clamping plate 42 is provided on the rotating shaft 41. A rotating ring 43 is rotatably installed between the two symmetrical groups of clamping plates 42. A material discharging frame 44 is provided in the rotating ring 43. Aluminum ingots are placed in the material discharging frame 44. End water spray plates 6, two sets of end water spray plates 6 are symmetrically installed in the sealing cover 2 near the position of the conveying roller 10, and the two sets of end water spray plates 6 spray water to cool the two ends of the aluminum ingot respectively; A spray assembly 7 is installed in the sealing cover 2 near the conveying roller 2 12, and the spray assembly 7 sprays water to cool the surface of the aluminum ingot; A toothed plate 8 is provided on the base 1 , and the toothed plate 8 is located in the sealing cover 2 and close to the second conveying roller 12 . A toothed ring 431 is provided on the side of the rotating ring 43 , and the toothed ring 431 is meshed with the toothed plate 8 .

[0018] Two sets of guide frames 23 are symmetrically installed in the sealing cover 2. The two sets of guide frames 23 are located on the inner sides of the two sets of conveyor belts 32. The rotating shaft 41 passes through the guide frames 23. Two sets of magnets 411 are symmetrically provided on the periphery of the rotating shaft 41. Two sets of magnetic parts 231 are symmetrically provided at the straight section of the guide frame 23. The two sets of magnetic parts 231 cooperate with the two sets of magnets 411 to prevent the rotating shaft 41 from rotating.

[0019] In actual application of this embodiment, the aluminum ingot after preliminary shaping is transferred to the conveyor roller 10, and the aluminum ingot is conveyed to the feed hole 21 by the conveyor roller 10, and then the aluminum ingot is pushed into the sealing cover 2 by extending the push plate 11. At this time, the discharge frame 44 on the placement rack 4 coincides with the feed hole 21, and the aluminum ingot is pushed into the discharge frame 44. The turntable 31 is rotated by the driving member 3, so that the conveyor belt 32 moves, and then the placement rack 4 drives the aluminum ingot to move upward first. In the process of moving upward, it first moves to between the two groups of end water spray plates 6. The two groups of end water spray plates 6 spray cooling water on both ends of the aluminum ingot respectively, so that both ends of the aluminum ingot are cooled down, and the placement rack 4 continues to move. When passing through the curved area of ​​the conveyor belt 32, since the guide frame 23 is not provided with a magnetic member 231 here, the rotating shaft 41 can be rotated, so that the discharge frame 44 is always in a horizontal state, avoiding the aluminum The ingot slides off the discharge frame 44, and when the placement rack 4 passes the curved area of ​​the conveyor belt 32, the placement rack 4 moves downward. When moving downward, the gear ring 431 on the rotating ring 43 will slowly approach the tooth plate 8. When the gear ring 431 moves to the tooth plate 8, the gear ring 431 rotates along the tooth plate 8, thereby causing the rotating ring 43 to rotate, and then the discharge frame 44 drives the aluminum ingot to rotate. At the same time, the spray assembly 7 sprays cooling water on the aluminum ingot to cool it down. Since the aluminum ingot is in a rotating state, all surfaces of the aluminum ingot can be in contact with the cooling water, thereby ensuring that the aluminum ingot is cooled evenly, avoiding affecting the casting quality of the aluminum ingot due to uneven cooling. When the aluminum ingot moves to the point where it coincides with the push plate 2 13, the gear ring 431 passes over the toothed area on the tooth plate 8, and the discharge frame 44 no longer rotates. The push plate 2 13 is extended to push the cooled aluminum ingot through the discharge hole 22 to the conveyor roller 2 12, completing a group of aluminum ingot cooling.

[0020] Furthermore, a plurality of adjusting rods 45 are installed at the diagonal positions inside the discharge frame 44 , and movable wheels 46 are rotatably installed at the ends of the adjusting rods 45 .

[0021] A plurality of elastic telescopic rods 432 are provided on the side of the swivel 43, and a connecting ring 48 is provided at the end of the plurality of elastic telescopic rods 432. A plurality of racks 47 are provided on the other side of the connecting ring 48. The racks 47 are U-shaped and extend into the discharge frame 44. A gear 461 is provided on the movable wheel 46, and the gear 461 and the rack 47 are engaged with each other. A corrugated plate 9 is provided on the base 1, and the corrugated plate 9 is located in the sealing cover 2. When the swivel 43 moves downward and rotates, the elastic telescopic rods 432 elastically extend and retract after hitting the corrugated plate 9.

[0022] When the present embodiment is actually used, when the aluminum ingot enters the discharge frame 44 through the feed hole 21, the surface of the aluminum ingot will contact with the plurality of movable wheels 46, which makes it convenient for the aluminum ingot to move into the discharge frame 44. The size formed between the plurality of movable wheels 46 can be adjusted by adjusting the length of the adjusting rod 45, so as to adapt to aluminum ingots of different sizes. When the placement rack 4 passes over the curved area above the conveyor belt 32 and moves downward, the swivel 43 will first drive the discharge frame 44 to rotate. When the swivel 43 rotates, the elastic telescopic rod 432 on the swivel 43 will slowly approach the wave plate 9. When the elastic telescopic rod 432 contacts the wave plate 9, the elastic telescopic rod 432 contracts under the extrusion of the wave plate 9. When the elastic telescopic rod 432 When the movable wheel 46 is rotated, the plurality of movable wheels 46 will drive the aluminum ingot to move, thereby causing the aluminum ingot to move back and forth, and the aluminum ingot will remain in a rotating state. When the aluminum ingot moves, the areas originally blocked by the discharge frame 44, the movable wheel 46, the rotating ring 43 and other structures can all be in contact with the cooling water, thereby further evenly cooling the aluminum ingot and avoiding affecting the casting quality of the aluminum ingot due to uneven cooling.

[0023] like Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10 As shown, an exhaust plate 5 is installed on the top of the sealing cover 2, and a spray assembly 7 is located on the side of the placement rack 4.

[0024] In actual application of this embodiment, the aluminum ingot that has been initially shaped still has a relatively high temperature. When the cooling water meets the aluminum ingot, a large amount of water vapor will be generated, and the water vapor may carry some oxides or impurities. If traditional cooling water is used to fall and contact the aluminum ingot, the rising water vapor will come into contact with the cooling water, and the cooling water may knock down the oxides in the water vapor, causing the oxides to return to the surface of the aluminum ingot. When the oxides return to the surface of the aluminum ingot, they may melt and embed into the aluminum matrix, forming hard inclusions, which will reduce the quality of the aluminum ingot. In addition, after the cooling water comes into contact with the water vapor, Since the temperature of water vapor is high, the temperature of the cooling water will rise before the cooling water contacts the aluminum ingot, thereby reducing the cooling effect of the cooling water. In the present invention, the spray assembly 7 sprays cooling water horizontally, and the generated water vapor moves upward under the action of the exhaust plate 5, so that the moving directions of the cooling water and water vapor are vertically staggered, thereby effectively avoiding contact between the cooling water and water vapor, effectively preventing oxides in the water vapor from returning to the surface of the aluminum ingot and affecting the quality of the aluminum ingot, and effectively preventing the temperature of the cooling water from rising before cooling the aluminum ingot, thereby avoiding reducing the cooling effect of the cooling water. At the same time, after the horizontally sprayed cooling water is sprayed onto the surface of the aluminum ingot, since the aluminum ingot is in a rotating state and the aluminum ingot rotates in the direction away from the spray assembly 7, the unevaporated cooling water flows downward along the aluminum ingot, so that the cooling water can pre-cool the surface of the aluminum ingot in advance, thereby improving the cooling effect, and the flow of cooling water along the surface of the aluminum ingot will increase the contact area between the cooling water and the aluminum ingot, thereby improving the cooling uniformity; in addition, the cooling water may wash away the original impurities on the surface of the aluminum ingot when flowing, effectively preventing these impurities from affecting the quality of the aluminum ingot.

[0025] Furthermore, the spray assembly 7 includes a guide groove 71, which is fixed on the base 1. A slider 72 is slidably installed in the guide groove 71, and an adjustment plate 73 is elastically rotatably installed on the slider 72. A plurality of nozzles 74 are installed on the adjustment plate 73, and the plurality of nozzles 74 are facing the placement rack 4.

[0026] A fixing plate 77 is provided in the guide groove 71, and an elastic member 78 is connected between the fixing plate 77 and the slider 72. An elastic telescopic rod 476 is provided at the bottom of the slider 72, and a pressure rod 421 is provided on the side of the splint 42. When the splint 42 moves downward, the pressure rod 421 pushes the elastic telescopic rod 476 downward.

[0027] In actual application of this embodiment, when the placement rack 4 moves downward, the pressure rod 421 on the clamping plate 42 will slowly contact the elastic telescopic rod 476, thereby pushing the elastic telescopic rod 476 downward, so that the slider 72 drives the adjustment plate 73 and the plurality of nozzles 74 to move downward, so that the plurality of nozzles 74 move downward with the placement rack 4, so that the sprayed cooling water always follows the aluminum ingot, which can reduce the use of cooling water on the one hand, and further avoid the cooling water from contacting with the rising water vapor on the other hand, further effectively preventing the water vapor from entering the aluminum ingot. The oxides return to the surface of the aluminum ingot and affect the quality of the aluminum ingot, further avoiding the reduction of the cooling effect of the cooling water; when the elastic telescopic rod four 76 contacts the fixed plate 77, the elastic telescopic rod four 76 no longer moves downward, and the pressure rod 421 will press down the elastic telescopic rod four 76, so that the elastic telescopic rod four 76 will contract, thereby causing the pressure rod 421 to pass over the elastic telescopic rod four 76. When the pressure rod 421 passes over the elastic telescopic rod four 76, the elastic member 78 rebounds, causing the slider 72 to drive the adjustment plate 73 and the plurality of nozzles 74 back to their original positions.

[0028] Furthermore, an adjusting piece 75 is installed on the adjusting plate 73, and the adjusting piece 75 includes a plurality of elastic telescopic rods 2 751, a plurality of elastic telescopic rods 3 752 and a bonding plate 753. One end of the elastic telescopic rod 2 751 and the elastic telescopic rod 3 752 are hinged to the adjusting plate 73, and the other ends of the elastic telescopic rod 2 751 and the elastic telescopic rod 3 752 are hinged to the bonding plate 753. The bonding plate 753 is bonded to the surface of the aluminum ingot on the placement rack 4. The hinges at both ends of the elastic telescopic rod 2 751 and the elastic telescopic rod 3 752 are elastically rotatably connected, so that when the adjusting piece 75 is in the initial state, the adjusting plate 73 is in a vertical state, and the elastic telescopic rod 2 751 and the elastic telescopic rod 3 752 are in a horizontal state.

[0029] In actual application of this embodiment, since the cross section of the aluminum ingot is trapezoidal, when the angle of the nozzle 74 remains unchanged, the sprayed cooling water may form an obtuse angle with the surface of the aluminum ingot, so that the cooling water will move obliquely upward along the surface of the aluminum ingot, thereby causing the cooling water to meet the rising water vapor; when the placement rack 4 moves downward, the sharp edges of the bottom of the aluminum ingot will squeeze the bonding plate 753, causing the elastic telescopic rod 2 751 and the elastic telescopic rod 3 752 to contract. When the sharp edges of the bottom of the aluminum ingot pass over the bonding plate 753, the bonding plate 753 will slowly fit on the surface of the aluminum ingot, which will cause the elastic telescopic rod 2 751 and the elastic telescopic rod 3 752 to different degrees. The contraction of the adjusting plate 73 causes the adjusting plate 73 to rotate, thereby changing the angles of the nozzles 74 so that the nozzles 74 are kept perpendicular to the surface of the aluminum ingot. The laminating plate 753 is always in contact with the surface of the aluminum ingot so that the nozzles 74 are always kept perpendicular to the surface of the aluminum ingot. In this way, the sprayed cooling water will be approximately perpendicular to the surface of the aluminum ingot. Since the cooling water will move downward due to its own gravity after being sprayed, it is difficult for the cooling water to move obliquely upward and contact the rising water vapor, which further effectively prevents the oxides in the water vapor from returning to the surface of the aluminum ingot and affecting the quality of the aluminum ingot, and further prevents the cooling effect of the cooling water from being reduced. While the cooling water is kept approximately perpendicular to the surface of the aluminum ingot, the aluminum ingot also keeps rotating, and the aluminum ingot rotates in the direction away from the spray assembly 7. In this way, under the action of centrifugal force, the water vapor will move obliquely upward after being generated, which can further avoid the contact between the cooling water and the water vapor, and further effectively avoid the oxides in the water vapor returning to the surface of the aluminum ingot to affect the quality of the aluminum ingot, and further avoid the reduction of the cooling effect of the cooling water.
