Description

Technical Field

[0001] This invention relates to the field of aluminum alloy ingot production technology, specifically a cooling device for aluminum alloy ingot production. Background Technology

[0002] The general process of aluminum alloy ingot casting is as follows: solid aluminum alloy raw materials are melted into liquid aluminum at high temperature, and the liquid aluminum is quantitatively poured into the forming mold on the circulating conveyor line; a circulating cooling water pool is set up below the entire conveyor line, and the mold relies on the water in the pool to immerse the bottom outer wall of the mold for heat exchange and cooling as the mold moves with the conveyor chain.

[0003] Existing cooling methods rely solely on single-sided heat dissipation from the bottom of the mold, with heat being conducted unidirectionally upwards. The upper space of the mold cavity is completely open, resulting in a significantly lower heat dissipation rate for the molten aluminum on the upper surface compared to the bottom, leading to a large temperature difference between the upper and lower melts. This results in two main problems: firstly, the upper part of the aluminum ingot solidifies slowly, making the surface highly susceptible to oxidation upon contact with air, leading to oxide inclusions and porosity defects; secondly, the overall crystal grain size of the casting is uneven, resulting in poor consistency in the mechanical properties of the aluminum alloy ingot. Therefore, we propose a cooling device for the production of cast aluminum alloy ingots. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling device for the production of cast aluminum alloy ingots, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for the production of cast aluminum alloy ingots, comprising a forming mold conveyor line and a support frame installed above the forming mold conveyor line, wherein a follow-up transmission mechanism is mounted on the support frame, and a plurality of cooling cover plates are uniformly mounted on the follow-up transmission mechanism.

[0006] The cooling cover plate has a cooling chamber for circulating cooling water. The cooling cover plate can move synchronously with the forming mold and cover the upper opening of the forming mold to achieve top-sealed synchronous cooling of the molten aluminum liquid inside the mold.

[0007] Each cooling cover is equipped with a water inlet assembly and a water outlet assembly on both sides, which are connected to the cooling chamber.

[0010] The fixed water inlet shell is fixedly installed on one side of the support frame, the water pump is assembled on the outside of the fixed water inlet shell, the output end of the water pump is connected to the inside of the fixed water inlet shell, and the input end of the water pump is connected to the external cooling water source.

[0011] The fixed water inlet shell is provided with a sealing guide rail and a sealing groove on the side facing the transmission water shell, and the sealing gasket is embedded in the sealing groove.

[0012] The transmission water shell is slidably assembled to the sealing guide rail of the fixed water inlet shell, and the side wall of the transmission water shell is sealed and fitted with the sealing gasket.

[0013] Multiple water guide shells are provided, with one end of each water guide shell connected to the interior of the transmission water shell, and the other end of each water guide shell connected to the water inlet end of the cooling chamber of the cooling cover plate.

[0014] Furthermore, the water outlet assembly includes a fixed water outlet shell, a hot water pump, a sealing ring, a movable water shell, and a water outlet pipe;

[0015] The fixed water outlet shell is fixedly installed on the other side of the support frame. The hot water pump is assembled on the outside of the fixed water outlet shell. The input end of the hot water pump is connected to the inside of the fixed water outlet shell, and the output end of the hot water pump is connected to the external water collection and recovery equipment.

[0016] The fixed water outlet shell is provided with a limiting guide rail on the side facing the moving water shell, and the sealing ring is embedded in the end face of the fixed water outlet shell;

[0017] The movable water shell is slidably assembled on the limiting guide rail, and the end face of the movable water shell is sealed and abutted against the sealing ring.

[0018] The water outlet pipe is provided in multiple ways. One end of each water outlet pipe is connected to the inside of the movable water shell, and the other end of each water outlet pipe is connected to the water outlet end of the cooling cavity of the cooling cover plate.

[0019] Furthermore, the fixed inlet shell, the transmission shell, the fixed outlet shell, and the movable shell are all configured as elliptical structures.

[0020] Furthermore, both the transmission water shell and the moving water shell are made of wear-resistant elastic sealing material, and both the transmission water shell and the moving water shell are fixedly provided with support ribs at equal intervals inside.

[0021] The supporting ribs are used to provide shape support for the water shell, so that the transmission water shell and the moving water shell always maintain a stable docking shape and ensure continuous sealing and water flow during sliding.

[0022] Furthermore, a movable cavity is provided inside the cooling cover plate, and a movable screw is rotatably installed inside the movable cavity plate. One end of the movable screw extends to the outside of the cooling cover plate and is equipped with a driving component.

[0023] The movable lead screw is threaded with a movable frame that can slide horizontally along the movable cavity, and the bottom of the movable frame is equipped with a movable scraper mechanism that can adaptively adjust the angle.

[0024] The cooling cover plate is connected to a slag suction pipe at its side end, and the slag suction pipes of each cooling cover plate are connected to an elliptical follower shell. The support frame is fixedly equipped with a slag suction shell that dynamically docks with the follower shell.

[0025] The outside of the slag suction shell is connected to a slag suction pump, and the discharge end of the slag suction pump is connected to a collection shell for collecting oxidized slag.

[0026] Furthermore, a plurality of first guide teeth are fixedly installed on the top side of the fixed water inlet shell, and a plurality of second guide teeth are fixedly installed on the bottom side of the fixed water inlet shell.

[0027] During the cyclical movement of the cooling cover, the driving component can intermittently engage with the first guide tooth block and the second guide tooth block respectively.

[0028] Furthermore, the movable slag scraping mechanism includes a scraper plate, a support shaft, and a positioning component;

[0029] The slag scraper is arranged on the inner side of the lower end face of the cooling cover plate, corresponding to the position of the aluminum liquid surface. The upper end of the slag scraper is rotatably hinged to the bottom of the moving frame through a support shaft.

[0030] The inner walls on both sides of the movable cavity are symmetrically provided with guide grooves. The positioning component is slidably engaged between the guide groove and the movable frame to limit the angle and guide the slag scraper.

[0032] The positioning block is slidably embedded inside the movable frame, and the movable frame has symmetrical moving openings on both sides;

[0033] Two limiting shafts are provided, and the two limiting shafts slide through the corresponding moving openings respectively. The inner end of the limiting shaft is fixedly connected to the positioning block, and the outer end of the limiting shaft is slidably engaged with the guide groove.

[0034] The positioning support rods are symmetrically hinged between the positioning block and the slag scraper. The two sets of positioning support rods form a triangular support structure, which allows the slag scraper to adaptively conform to the angle of the aluminum liquid surface.

[0035] This invention has at least the following beneficial effects:

[0036] 1. The present invention adopts a follow-up cooling cover plate that runs at the same speed and synchronously with the conveying mold. The cover plate fastens to the upper opening of the mold to form a closed cavity. Forced water cooling of the upper surface is achieved by relying on the cooling cavity inside the cover plate. Combined with the original bottom water pool cooling, a bidirectional synchronous heat exchange mode is formed to ensure that the aluminum liquid solidifies evenly and stably.

[0037] 2. Unlike traditional water-cooled cover plates, which are all fixed structures and can only be used when the machine is stopped, making them completely unsuitable for automated ingot casting production lines with continuous circulating conveying, this invention relies on an independent chain plate follow-up transmission mechanism. Multiple sets of cooling cover plates circulate and follow the mold continuously, maintaining a closed cooling state throughout the entire production process under uninterrupted production conditions. This eliminates the process of waiting for the mold to cool statically, significantly reducing the total processing time for forming a single aluminum ingot and significantly improving the continuous production capacity of the entire production line.

[0038] 3. The present invention integrates a screw-driven slag scraping mechanism inside the cooling cover plate. The upper and lower guide teeth are fixedly arranged on the production line. During the circulation of the cooling cover plate, they automatically touch and trigger the drive to reverse forward and reverse. There is no need to add PLC electrical control program, displacement sensor and other electrical control components. The slag scraping plate reciprocates to clean the oxide slag on the surface of the aluminum liquid by relying on the pure mechanical structure. Attached Figure Description

Detailed Implementation

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1

[0057] Please see Figures 1 to 7A cooling device for the production of cast aluminum alloy ingots includes a forming mold conveyor line 1 and a support frame 2 installed above the forming mold conveyor line 1. In this application, the forming mold conveyor line 1 runs continuously and uniformly in a cyclical manner, and a casting mechanism is also provided at the existing forming mold conveyor line 1. The casting mechanism sequentially pours molten aluminum onto each forming mold. After the casting is completed, the forming mold moves forward with the conveyor line, and the existing cooling water pool is correspondingly set at the bottom of the forming mold conveyor line 1, which is not shown in the figure.

[0058] The support frame 2 is equipped with a follower transmission mechanism 3, and a number of cooling cover plates 4 are evenly mounted on the follower transmission mechanism 3.

[0059] The follow-up transmission mechanism 3 includes a chain plate type conveyor belt 31 mounted on the support frame 2. Each chain plate of the chain plate type conveyor belt 31 is fixedly mounted with a connecting block 32, and the cooling cover plate 4 is fixedly mounted on the connecting block 32 one by one.

[0060] In this application, the support frame 2 erected on the forming mold conveyor line 1 remains fixed, and the chain plate conveyor belt 31 on the support frame 2 keeps running synchronously at the same speed as the forming mold conveyor line 1. In this application, the length of the chain plate conveyor belt is less than the length of the forming mold conveyor line 1, thereby ensuring that the forming mold can retain the space for casting, so that the mold can be fully cast. At the same time, after the aluminum alloy ingot in the forming mold is formed, it can be accurately demolded at the other end.

[0061] The cooling cover plate 4 has a cooling chamber 41 for circulating cooling water. The cooling cover plate 4 can move synchronously with the forming mold and cover the upper opening of the forming mold to achieve top-sealed synchronous cooling of the molten aluminum liquid inside the mold.

[0062] Each cooling cover plate 4 is equipped with a water inlet assembly 5 and a water outlet assembly 6 on both sides, which are connected to the cooling chamber 41. The water inlet assembly 5 and the water outlet assembly 6 work together to achieve continuous water circulation and heat exchange inside the cooling cover plate 4. In this application, the water inlet assembly 5 and the water outlet assembly 6 always maintain a dynamic sealed water flow state during the entire operation of the production line.

[0063] The water inlet assembly 5 includes a fixed water inlet shell 51, a water pump 52, a sealing gasket 53, a transmission water shell 54, and a water guide shell 55;

[0064] The fixed water inlet shell 51 is fixedly installed on one side of the support frame 2. The water pump 52 is assembled on the outside of the fixed water inlet shell 51. The output end of the water pump 52 is connected to the inside of the fixed water inlet shell 51, and the input end of the water pump 52 is connected to the external cooling water source.

[0065] A sealing guide rail and a sealing groove are provided on the side of the fixed water inlet shell 51 facing the transmission water shell 54, and the sealing gasket 53 is embedded in the sealing groove.

[0066] The transmission water housing 54 is slidably assembled to the sealing guide rail of the fixed water inlet housing 51, and the side wall of the transmission water housing 54 is sealed and fitted with the sealing gasket 53.

[0067] Multiple water guide shells 55 are provided. One end of each water guide shell 55 is connected to the inside of the transmission water shell 54, and the other end of each water guide shell 55 is connected to the water inlet end of the cooling cavity 41 of the cooling cover plate 4.

[0068] The water outlet assembly 6 includes a fixed water outlet shell 61, a hot water pump 62, a sealing ring 63, a movable water shell 64, and a water outlet pipe 65;

[0069] The fixed water outlet shell 61 is fixedly installed on the other side of the support frame 2. The hot water pump 62 is assembled on the outside of the fixed water outlet shell 61. The input end of the hot water pump 62 is connected to the inside of the fixed water outlet shell 61, and the output end of the hot water pump 62 is connected to the external water collection and recycling equipment.

[0070] A limiting guide rail is provided on the side of the fixed water outlet shell 61 facing the movable water shell 64, and the sealing ring 63 is embedded in the end face of the fixed water outlet shell 61.

[0071] The movable water shell 64 is slidably mounted on the limiting guide rail, and the end face of the movable water shell 64 is in sealing contact with the sealing ring 63.

[0072] Multiple water outlet pipes 65 are provided. One end of each water outlet pipe 65 is connected to the inside of the movable water shell 64, and the other end of each water outlet pipe 65 is connected to the water outlet end of the cooling cavity 41 of the cooling cover plate 4.

[0073] The fixed inlet shell 51, the transmission shell 54, the fixed outlet shell 61, and the movable shell 64 are all designed with an elliptical structure.

[0074] Both the transmission water housing 54 and the movable water housing 64 are made of wear-resistant elastic sealing material, and both the transmission water housing 54 and the movable water housing 64 are fixedly provided with support ribs at equal intervals inside.

[0075] The supporting stiffeners are used to shape and support the water shell, so that the transmission water shell 54 and the moving water shell 64 always maintain a stable docking shape, and ensure continuous sealing and water flow during sliding.

[0076] The present invention adopts an elliptical shell structure with internal support ribs, which enables the transmission water shell 54 and the moving water shell 64 to maintain structural shape and elastic fit during long-term sliding friction, greatly improving dynamic sealing stability and effectively solving the defects of traditional mobile water cooling structures that are prone to water leakage, pipe pulling, and unstable water supply.

[0077] Specific implementation process: In this application, while the forming mold after the aluminum liquid is poured moves along the forming mold conveyor line 1, the chain plate transmission belt runs synchronously, and the corresponding cooling cover plate 4 covers the opening at the upper end of the forming mold. At this time, the water pump 52 continuously pumps external cooling water into the fixed water inlet shell 51. The fixed water inlet shell 51 slides and seals with the transmission water shell 54 that can move with the cooling cover plate 4 through the sealing gasket 53 and the sealing guide rail. Then the cooling water flows into the cooling chamber 41. At this time, a cooling space is formed on the forming mold. At the same time, combined with the cooling water pool below the forming mold, the aluminum liquid inside the forming mold is fully and uniformly cooled.

[0078] Meanwhile, the hot water heated inside the cooling chamber 41 flows into the movable water shell 64 through the outlet pipe 65 at the other end. The movable water shell 64 and the fixed outlet shell 61 are connected by a sealing ring 63 and a limiting guide rail. The hot water pump 62 works continuously to extract the high-temperature hot water inside the fixed outlet shell 61 and transport it to an external water collection device to complete the circulation and recycling. This allows each moving cooling cover plate 4 to achieve uninterrupted closed-loop water circulation cooling under moving conditions.

[0079] Example 2

[0080] Please see Figures 4 to 15 Example 2 is a further supplementary explanation of Example 1, specifically as follows:

[0081] The cooling cover plate 4 has a movable cavity 42 inside, and a movable screw 7 is rotatably installed inside the movable cavity 42. One end of the movable screw 7 extends to the outside of the cooling cover plate 4 and is equipped with a driving component 71.

[0082] As a further supplementary explanation, the drive component 71 includes a protective shell 711, a first drive gear 712, a second drive gear 713, a rotating rod 714, and a rotating gear 715. The protective shell 711 is fixedly installed on one side outside the cooling cover plate 4. The first drive gear 712 is fixedly connected to one end of the moving lead screw 7 that extends to the outside of the cooling cover plate 4. The second drive gear 713 is meshed with the first drive gear 712.

[0083] The protective shell 711 is located outside the first drive gear 712 and the second drive gear 713. One end of the rotating rod 714 is rotatably connected to the cooling cover plate 4, and the rotating rod 714 passes through the protective shell 711. The other end of the rotating rod 714 is fixedly connected to the rotating gear 715. The rotating rod 714 is rotatably connected to the cooling cover plate 4.

[0084] The movable lead screw 7 is threaded with a movable frame 72 that can slide horizontally along the movable cavity 42, and the bottom of the movable frame 72 is equipped with a movable scraper mechanism 8 that can adaptively adjust the angle.

[0085] The cooling cover plate 4 is connected to a slag suction pipe 73 on one side. In this application, the end of the slag suction pipe 73 located inside the movable cavity 42 is also connected to a slag suction head 731, and the slag suction head 731 is set in a trapezoidal funnel shape. Furthermore, a switch valve 732 is installed at the slag suction pipe 73. The cooling cover plate 4 is provided with a receiving groove at the valve stem 733 corresponding to the switch valve 732. A worm gear 734 is fixedly installed on the outside of the valve stem 733. A worm 735 is meshed on the outside of the worm gear 734. The worm 735 is rotatably connected inside the receiving groove. A connecting gear 736 is fixedly connected to one end of the worm 735. A push rack 722 is fixedly installed on one side of the movable frame 72. The slag suction pipes 73 of each cooling cover plate 4 are connected to an elliptical follower shell 74. A slag suction shell 75 that dynamically docks with the follower shell 74 is fixedly assembled on the support frame 2.

[0086] Specific implementation process: In this application, when the moving frame 72 moves the slag scraper 81 to scrape off the floating slag on the surface of the molten aluminum, and the slag scraper 81 moves to the slag suction head 731 and is in an inclined state, the slag scraper 81 approaches and fits against the slag suction head 731. During this process, the push rack 722 at the moving frame 72 drives the connecting gear 736, thereby causing the worm 735 to drive the worm wheel 734 to rotate, thereby opening the switch valve 732 at the slag suction pipe 73. At this time, the slag suction pipe 73 and the slag suction head 731 achieve the effect of fully removing the floating slag on the surface of the slag scraper 81.

[0087] A slag suction pump 76 is connected to the outside of the slag suction shell 75, and a collection shell for collecting oxidized slag is connected to the discharge end of the slag suction pump 76.

[0088] A number of first guide teeth 9 are fixedly installed on the top side of the fixed water inlet shell 51, and a number of second guide teeth 91 are fixedly installed on the bottom side of the fixed water inlet shell 51.

[0089] During the cyclical movement of the cooling cover plate 4, the drive component 71 can intermittently abut against the first guide tooth block 9 and the second guide tooth block 91 respectively. The forward and reverse rotation of the drive component 71 is triggered by the push of the tooth block, thereby driving the moving lead screw 7 to rotate in both directions.

[0090] The mobile slag scraping mechanism 8 includes a slag scraper 81, a support shaft 82, and a positioning component 83;

[0091] The slag scraper 81 is arranged on the inner side of the lower end face of the cooling cover plate 4, corresponding to the position of the molten aluminum. The upper end of the slag scraper 81 is rotatably hinged to the bottom of the movable frame 72 via the support shaft 82, as shown in the instruction manual. Figure 15 In this application, the slag scraper 81 is also provided with a surrounding edge on both sides, thereby preventing the slag from falling off the slag scraper 81.

[0092] The inner walls of the movable cavity 42 are symmetrically provided with guide grooves 43. The positioning member 83 is slidably engaged between the guide groove 43 and the movable frame 72 to limit the angle and guide the slag scraper 81. In this application, the two ends of the guide groove 43 are respectively provided with a first inclined section 431 and a second inclined section 432, and a transverse section 433 is provided in the middle of the guide groove 43. In this application, when the slag scraper 81 is in the first inclined section 431 along with the limiting shaft 832, the slag scraper 81 is in a retracted state. When it moves to the transverse section 433, the slag scraper 81 extends into the forming mold and scrapes off the slag on the surface of the aluminum liquid. At the same time, when it moves to the second inclined section 432, the slag scraper 81 is in an inclined position and fits against the slag suction head 731. The slag suction pump 76 runs to completely adsorb and remove the slag on the slag scraper 81.

[0093] Positioning component 83 includes positioning block 831, limiting shaft 832, and positioning support rod 833;

[0094] The positioning block 831 is slidably embedded inside the movable frame 72, and the movable frame 72 has symmetrical movable openings 721 on both sides;

[0095] Two limiting shafts 832 are provided. The two limiting shafts 832 slide through the corresponding moving openings 721 respectively. The inner end of the limiting shaft 832 is fixedly connected to the positioning block 831, and the outer end of the limiting shaft 832 slides in cooperation with the guide groove 43.

[0096] The positioning support rod 833 is symmetrically hinged between the positioning block 831 and the slag scraper 81. The two sets of positioning support rods 833 form a triangular support structure, which allows the slag scraper 81 to adaptively conform to the angle of the aluminum liquid surface.

[0097] Specific implementation process: In this application, after the cooling cover plate 4 is docked with the corresponding forming mold, the cooling water flows in the cooling chamber 41, which fully and evenly cools the aluminum liquid inside the forming mold. At the same time, when the corresponding cooling cover plate 4 moves to the position of several first guide tooth blocks 9, the driving component 71 drives the moving screw 7 to rotate. When the moving screw 7 rotates, it provides driving force to the moving frame 72. The moving frame 72 drives the positioning block 831 and the slag scraper 81 to move synchronously through the limiting shaft 832. Due to the limiting effect of the guide groove 43, the positioning block 831 adjusts the tilt angle of the slag scraper 81 through the positioning support rod 833, so that the slag scraper 81 can fully scrape off the floating slag on the surface of the aluminum liquid. Then, when the slag scraper 81 is attached to the slag scraper head, the corresponding slag suction pipe 73 opens, which can fully adsorb and remove the floating slag and other impurities at the slag scraper 81.

[0098] Meanwhile, in this application, during the operation of the follow-up transmission mechanism 3, the slag suction pump 76 is always in the open state, and when the drive component 71 moves to the position of several second guide tooth blocks 91, the moving screw 7 rotates in the opposite direction. At this time, the push rack 722 at the moving frame 72 disengages from the connecting tooth block, and the corresponding slag suction pipe 73 closes. As the moving screw 7 continues to run, the slag scraper 81 returns to its original position, thus preparing to cool the aluminum liquid at the next forming mold.
