Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal casting technology, and in particular to an aluminum alloy casting crystallizer. Background Technology

[0002] The aluminum alloy casting crystallizer is a core component in the continuous aluminum alloy casting process. It primarily guides the solidification of molten aluminum into shape, controlling the heat transfer rate through an external cooling system, directly influencing the ingot's crystalline structure, surface quality, and internal density. The uniformity and stability of its cooling performance have a decisive impact on ingot quality. Especially in the critical ingot forming stage, existing crystallizers have gradually revealed a series of significant limitations and technical problems in meeting the demands of high-efficiency, high-quality casting.

[0003] Utility model patent CN208214255U discloses an aluminum alloy casting crystallizer. Although it is equipped with multiple sets of water inlets and water flow sensors, and monitors the water volume through a control box, improving the controllability of the cooling process, it lacks an externally interconnected and independently adjustable dual-channel water inlet structure. This means that when dual water supply is required, it must rely on two independent water sources, resulting in low system integration, complex piping, and increased installation and maintenance difficulty.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a new type of aluminum alloy casting crystallizer to solve this problem. This novel crystallizer should be able to achieve external connectivity and independent control of dual-channel water inlet, improve the redundancy and operational flexibility of the cooling system, and better meet the production requirements of high efficiency, stability, and intelligent control, thus providing strong support for the sustainable development of the aluminum alloy casting industry. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum alloy casting crystallizer that solves the problem of existing technologies lacking an externally interconnected and independently adjustable dual-channel water inlet structure. This results in reliance on two independent water sources when dual water supply is required, leading to low system integration, complex piping, and increased installation and maintenance difficulties.

[0006] To achieve the above objectives, this utility model provides an aluminum alloy casting crystallizer, including an aluminum alloy casting crystallizer body and two water inlet pipes disposed on the top of one side of the aluminum alloy casting crystallizer body. A water supply pipe is disposed on one side of the aluminum alloy casting crystallizer body. One end of the water supply pipe is provided with a top pipe and a bottom pipe. The bottom pipe is connected to the bottom of the top pipe through a connecting pipe. The top end of the top pipe is connected to the bottom of the water supply pipe.

[0007] A water supply pipe is connected to one side of both the top pipe and the bottom pipe, and the end of the water supply pipe is detachably connected to the end of the adjacent water inlet pipe.

[0008] The bottom end of the top tube has a bottom opening, and a tapered plug is provided inside the bottom opening. The bottom of the tapered plug is connected to an adjusting screw with one end threaded through the bottom tube.

[0009] Each of the two inlet pipes is fixedly connected to a connecting flange at one end, and each of the two outlet pipes is fixedly connected to a mating flange that is bolted to the connecting flange at one end.

[0010] The top end of the connecting tube is fixedly connected to the bottom end of the top tube, the bottom of the inner ring of the connecting tube is provided with an internal thread, and the top of the bottom tube is connected to an external threaded tube.

[0011] The water supply pipe has a tapered pipe that is adapted to the inside of the water inlet pipe at one end, and sealing rings are connected to the sides of the docking flange and the connecting flange that are close to each other.

[0012] The bottom end of the adjusting screw is fixedly connected to a rotating handle, and the length of the adjusting screw is greater than the length of the bottom tube.

[0013] The outer ring of the rotating handle is connected to several grip rods, and the outer ring of each grip rod is connected to an anti-slip sleeve.

[0014] This utility model discloses an aluminum alloy casting crystallizer. Through a combination of a water supply pipe, a top pipe, a bottom pipe, and a connecting pipe, it forms a dual-channel water inlet system with interconnected external connections. This solves the problem in existing technologies that require two independent water sources for dual-channel water supply, significantly improving system integration and pipeline layout simplicity, and reducing installation and maintenance complexity. The top and bottom pipes are detachably connected to the water inlet pipe via water supply pipes, allowing for flexible adjustment of the water supply path and facilitating the selection of single-sided or dual-sided water supply modes according to actual working conditions. Specifically, by setting a bottom opening at the bottom of the top pipe and installing a conical plug driven by an adjusting screw inside, it achieves top-to-bottom... The controllable adjustment of the connection between the main pipe and the bottom pipe allows for the sealing or opening of the bottom opening by rotating the adjusting screw. This enables on / off control between the two channels, allowing for the independent closure of a branch in case of a fault or maintenance requirement without affecting the normal water supply of the other branch. This ensures the continuity of the casting process and the redundancy of the cooling system. The structure avoids the risk of the entire cooling system shutting down due to a single point of failure, improving the stability and reliability of the equipment. The fit between the conical plug and the bottom opening provides excellent sealing performance, ensuring no leakage when closed. The threaded drive of the adjusting screw provides smooth operation and precise control, facilitating manual adjustment on-site. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, an aluminum alloy casting crystallizer of this embodiment includes an aluminum alloy casting crystallizer body 3 and two water inlet pipes 2 disposed on the top of one side of the aluminum alloy casting crystallizer body 3. A water supply pipe 1 is disposed on one side of the aluminum alloy casting crystallizer body 3. A top pipe 7 and a bottom pipe 5 are disposed at one end of the water supply pipe 1. The bottom pipe 5 is connected to the bottom of the top pipe 7 through a connecting pipe 6. The top end of the top pipe 7 is connected to the bottom of the water supply pipe 1.

[0025] A water supply pipe 16 is connected to one side of both the top pipe 7 and the bottom pipe 5, and the end of the water supply pipe 16 is detachably connected to the end of the adjacent water inlet pipe 2.

[0026] The bottom end of the top tube 7 has a bottom opening 15, and a tapered plug 12 is provided inside the bottom opening 15. The bottom of the tapered plug 12 is connected to an adjusting screw 11 with one end threaded through the bottom tube 5.

[0027] Workflow: When using this aluminum alloy casting crystallizer, first install the aluminum alloy casting crystallizer body 3 in the designated position of the casting equipment, ensuring that it is aligned with the casting platform and firmly fixed; the water supply pipe 1 is set on one side of the aluminum alloy casting crystallizer body 3, and its bottom is connected to the top pipe 7. The bottom end of the top pipe 7 is connected to the bottom pipe 5 through the connecting pipe 6, forming an externally connected dual-channel water supply structure; when cooling water enters from the water supply pipe 1, the water flow can flow into the top pipe 7 and the bottom pipe 5 simultaneously or selectively; the top pipe 7 and the bottom pipe 5 are respectively connected to the side of the water supply pipe 16, and the end of the water supply pipe 16 is detachably connected to the water inlet pipe 2 set on the top of one side of the aluminum alloy casting crystallizer body 3, thereby delivering cooling water to the cooling water channel inside the crystallizer to achieve uniform cooling of the ingot; under normal operating conditions, if dual-channel water supply is required, the adjusting screw 11 is in the loose state, and the conical plug 12 does not completely seal the bottom opening 1. 5. Maintain communication between the top pipe 7 and the bottom pipe 5, allowing water to flow between the two pipes via the connecting pipe 6, achieving dual-path coordinated water supply and improving cooling efficiency. When one side of the inlet pipe 2 or the delivery pipe 16 needs maintenance, replacement, or becomes blocked, the adjusting screw 11 can be rotated to allow its thread to pass through the bottom pipe 5 and push the conical plug 12 downwards, tightly embedding it into the bottom opening 15, thereby cutting off the communication path between the top pipe 7 and the bottom pipe 5 and achieving independent closure of the bottom pipe 5. At this time, cooling water is supplied to the corresponding inlet pipe 2 only through the top pipe 7 and its connected delivery pipe 16, while the other side stops supplying water, without affecting the continuity of the overall casting process. After maintenance, the adjusting screw 11 is rotated in the opposite direction to remove the conical plug 12, restoring the communication between the two pipes, and the dual-channel water supply mode can be restarted. The detachable connection between the delivery pipe 16 and the inlet pipe 2 also facilitates quick disassembly and replacement, improving maintenance efficiency.

[0028] Example 2

[0029] Please see Figure 1-5 As shown in this embodiment, an aluminum alloy casting crystallizer has a connecting flange 8 fixedly connected to one end of each of the two water inlet pipes 2, and a docking flange 10 fixedly connected to the connecting flange 8 with bolts at one end of each of the two water delivery pipes 16. Specifically, by cooperating with the connecting flange 8 at one end of the two water inlet pipes 2 and the docking flange 10 at one end of the water delivery pipe 16 and fixing them with bolts, the docking flange 10 and the connecting flange 8 are aligned and tightened with bolts during installation, realizing a detachable connection between the water delivery pipe 16 and the water inlet pipe 2. The operation is simple and the connection is firm, achieving the effect of improving connection stability and maintenance and disassembly convenience.

[0030] One end of the water supply pipe 16 is fixedly connected to a tapered pipe 9 that is adapted to the interior of the water inlet pipe 2. Sealing rings are connected to the sides of the mating flange 10 and the connecting flange 8 that are close to each other. Specifically, by setting a tapered pipe 9 at one end of the water supply pipe 16 to be adapted to the interior of the water inlet pipe 2, and by setting sealing rings on the sides of the mating flange 10 and the connecting flange 8 that are close to each other, the sealing rings are deformed under pressure during the tightening of the flange bolts to fill the gap between the flange surfaces. At the same time, the tapered pipe 9 is inserted into the water inlet pipe 2 to achieve guidance and sealing, effectively preventing cooling water leakage. This achieves the effects of enhancing the sealing performance of the interface, preventing leakage, and improving the safety of the system.

[0031] Example 3

[0032] Please see Figure 1-5 As shown in this embodiment, an aluminum alloy casting crystallizer has a connecting pipe 6 whose top end is fixedly connected to the bottom end of a top pipe 7. The bottom of the inner ring of the connecting pipe 6 is provided with an internal thread 14, and the top of the bottom pipe 5 is connected with an external threaded pipe 13. Specifically, by fixing the top end of the connecting pipe 6 to the bottom end of the top pipe 7, and providing an internal thread 14 at the bottom end of the inner ring of the connecting pipe 6, and providing an external threaded pipe 13 at the top end of the bottom pipe 5, the external threaded pipe 13 is screwed into the internal thread 14 to achieve a threaded connection between the bottom pipe 5 and the connecting pipe 6, thereby completing the assembly between the bottom pipe 5 and the top pipe 7. This achieves the effects of easy disassembly and assembly, ensuring sealing, and improving the reliability of the structural connection.

[0033] A rotating handle 4 is fixedly connected to the bottom end of the adjusting screw 11. The length of the adjusting screw 11 is greater than the length of the bottom tube 5. Specifically, by setting the rotating handle 4 at the bottom end of the adjusting screw 11 and setting the length of the adjusting screw 11 to be greater than the length of the bottom tube 5, the operator can manually rotate the rotating handle 4 to drive the adjusting screw 11 to rise and fall on the bottom tube 5, thereby controlling the insertion or withdrawal of the conical plug 12 into or out of the bottom opening 15. Even when the bottom tube 5 is long, full-range adjustment can be achieved, which achieves the effect of convenient manual operation, improved adjustment convenience and control accuracy.

[0034] The outer ring of the rotating handle 4 is connected to several grip rods, and the outer ring of each grip rod is connected to an anti-slip sleeve. Specifically, by rotating the outer ring of the handle 4 to set several grip rods, and by setting the outer ring of each grip rod to be connected to an anti-slip sleeve, the force application radius is increased and the friction of the hand grip is improved. Especially in wet or oily environments, it can still apply force stably and prevent slippage, thereby achieving the effects of enhancing operational safety, reducing labor intensity and improving ergonomic performance.

[0035] When using this aluminum alloy casting crystallizer, first install the aluminum alloy casting crystallizer body 3 in the designated position of the casting equipment and fix it firmly. The water supply pipe 1 is set on one side of the aluminum alloy casting crystallizer body 3, and its bottom is connected to the top pipe 7. The bottom end of the top pipe 7 is connected to the bottom pipe 5 through the connecting pipe 6. The top end of the connecting pipe 6 is fixedly connected to the top pipe 7, and its inner ring bottom is provided with an internal thread 14. The top of the bottom pipe 5 is provided with an external thread pipe 13. The threaded connection between the two is achieved by screwing the external thread pipe 13 into the internal thread 14, which facilitates disassembly and assembly and ensures continuity. For sealing, cooling water enters from the supply pipe 1 and flows into the top pipe 7 and the bottom pipe 5. A water delivery pipe 16 is connected to one side of each of the top pipe 7 and the bottom pipe 5. One end of the water delivery pipe 16 has a tapered pipe 9, which can be inserted into the inlet pipe 2 for guidance and sealing. The other end of the water delivery pipe 16 has a connecting flange 10, which is aligned with the connecting flange 8 at the end of the inlet pipe 2 and then fastened with bolts. Sealing rings are provided on the sides of the connecting flange 10 and the connecting flange 8 that are close to each other. When the bolts are tightened, the sealing rings deform to fill the gap, effectively preventing cooling water leakage. When simultaneous water supply from both channels is required, the adjusting screw 11 is in the loosened state, and the conical plug 12 at its bottom does not completely seal the bottom opening 15 at the bottom end of the top pipe 7, allowing the top pipe 7 and the bottom pipe 5 to remain connected through the connecting pipe 6. Cooling water can be simultaneously delivered to both inlet pipes 2 via the water supply pipe 16, achieving dual-path coordinated cooling. When maintenance is required on one side of the water supply pipe 16 or the inlet pipe 2, the operator rotates the handle 4, which is fixedly connected to the bottom end of the adjusting screw 11. The length of the adjusting screw 11 is greater than the length of the bottom pipe 5, ensuring complete retraction. The conical plug 12 is removed; the outer ring of the rotating handle 4 is equipped with multiple gripping rods, each of which is covered with an anti-slip sleeve to facilitate stable force application in humid or oily environments. Rotating the adjusting screw 11 moves it downward, pushing the conical plug 12 tightly into the bottom opening 15, cutting off the passage between the top pipe 7 and the bottom pipe 5, and realizing the independent closure of the water supply to the bottom pipe 5 side. At this time, the cooling water is only supplied through the path of the top pipe 7 side, ensuring the continuous operation of the casting process; after maintenance, the rotating handle 4 is rotated in the opposite direction to remove the conical plug 12 and restore the dual-channel connection. The device forms a dual-channel water supply structure with external connectivity through the combination of top pipe 7, bottom pipe 5, and connecting pipe 6, solving the problem of dependence on dual water sources and improving system integration. The adjusting screw 11 and the conical plug 12 can control the on / off state between the two channels, improving system redundancy and operational reliability. The bolted connection between the connecting flange 8 and the docking flange 10 facilitates disassembly and maintenance. The conical pipe 9 and the sealing ring work together to enhance the interface sealing and prevent leakage. The threaded connection between the external threaded pipe 13 and the internal threaded pipe 14 facilitates the assembly of the connecting pipe 6 and the bottom pipe 5. The design of the rotating handle 4, its grip rod, and the anti-slip sleeve improves the ease of operation and safety.
