Description

Technical Field

[0001] This disclosure relates to the technical field of metallurgical equipment, and in particular to an aluminum liquid transfer device and aluminum smelting equipment. Background Technology

[0002] In the aluminum smelting and casting process, the transfer of molten aluminum in the furnace is a crucial step, especially in the production of precision aluminum alloy products such as new energy vehicles and electronically controlled valve bodies, where higher requirements are placed on the purity of the molten aluminum and the efficiency of its transfer.

[0003] In the aluminum smelting industry, traditional aluminum molten metal transfer channels are typically fixed, with one end connected to the furnace outlet and the other extending above the transfer ladle. However, fixed transfer channels have significant limitations: First, during the transfer or replacement of transfer ladles, operators must adjust or move the fixed transfer channel, which not only increases labor intensity but also reduces transfer efficiency. Furthermore, there are safety hazards such as aluminum splashing or burns during the transfer process. Second, to ensure smooth flow of molten aluminum, the entire furnace body usually needs to be raised to create the necessary height difference, which increases the complexity of equipment installation and operation, hinders material feeding, and further exacerbates safety risks. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an aluminum liquid transfer device and aluminum smelting equipment that are simple in structure and flexible in operation.

[0010] When the molten aluminum is not being transferred, the power output end of the lifting drive assembly is located at the second height position, the support assembly abuts against the bottom of the movable groove, and the connection angle between the fixed groove and the movable groove is a preset angle, which is less than 180°, so that the angle between the liquid guiding direction of the fixed groove and the liquid guiding direction of the movable groove is equal to the preset angle; the height of the first height position is less than the height of the second height position.

[0011] In one embodiment, the support assembly includes a first support column and a second support column, the first support column being connected to the power output end of the lifting drive assembly, the second support column being connected to the outer peripheral wall of the first support column, and the end of the second support column away from the first support column being disposed near the furnace body.

[0012] The top of the first support column is rotatably provided with a first roller, and the end of the second support column adjacent to the furnace body is rotatably provided with a second roller;

[0013] When the power output end of the lifting drive assembly is at the second height position, both the first roller and the second roller roll against the bottom of the movable groove.

[0014] When the power output end of the lifting drive assembly is at the third height position, the connection angle between the fixed groove and the movable groove is the first transition angle, the first transition angle is greater than 120°, the first transition angle is less than 150°, and the first roller abuts against the bottom of the movable groove.

[0015] When the power output end of the lifting drive assembly is at the fourth height position, the connection angle between the fixed groove and the movable groove is the second transition angle, which is less than 120°. The first roller and the second roller both abut against the bottom of the movable groove. The first height position, the second height position, the third height position and the fourth height position are, from high to low, the second height position, the fourth height position, the third height position and the first height position.

[0016] In one embodiment, the end of the second support column is welded to the outer peripheral wall of the first support column.

[0017] In one embodiment, the rotating assembly includes a connecting plate and a rotating seat. The two side walls of the movable groove adjacent to one end of the fixed groove are provided with the connecting plate, and the two side walls of the fixed groove adjacent to one end of the movable groove are correspondingly provided with the rotating seat. The rotating seat is rotatably connected to the connecting plate.

[0018] In one embodiment, the preset included angle ranges from 90° to 150°.

[0023] An aluminum smelting equipment includes a furnace body, a transfer bag, and an aluminum liquid transfer device as described in any of the above embodiments.

[0024] Compared with the prior art, this disclosure has at least the following advantages:

[0025] Unlike traditional methods that involve raising the furnace body to create a height difference, the aluminum molten metal transfer device disclosed herein lowers the transfer bag via the power output end of a lifting drive component, thereby creating a height difference between the transfer bag and the furnace body's discharge port. The molten aluminum inside the furnace flows into the transfer bag through a reversible flow channel. Therefore, it is unnecessary to raise the furnace body to meet the required height difference for transportation, thus improving the convenience and safety of material feeding.

[0026] The reversible flow channel consists of a fixed channel and a movable channel. The fixed channel is fixedly connected to the furnace body, while the movable channel rotates relative to the fixed channel via a rotating assembly. A support assembly, raised by the power output of the lifting drive assembly, comes into contact with and supports the movable channel, ensuring it remains in its reversed state. This automatic reversing function separates the movable channel from the transfer package, facilitating the transfer and replacement of the package by workers, reducing their workload, and improving the efficiency and safety of molten aluminum transfer.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0038] Please see Figures 1 to 6The aluminum liquid transfer device 10, as an embodiment of this utility model, includes a reversible flow channel 100 and a lifting support mechanism 200. The reversible flow channel 100 is used to transfer aluminum liquid and includes a fixed channel 110, a movable channel 120, and a rotating assembly 130. The fixed channel 110 and the movable channel 120 are rotatably connected via the rotating assembly 130, making the connection angle between them adjustable. One end of the fixed channel 110 extends below the outlet of the furnace body 21, and the end of the movable channel 120 away from the fixed channel 110 is movably abutting against the transfer bag 22. The lifting support mechanism 200 includes a lifting drive assembly 210 and a support assembly 220. The lifting drive assembly 210 is disposed on the side adjacent to the outlet of the furnace body 21, and the support assembly 220 is connected to the power output end of the lifting drive assembly 210.

[0039] When transferring molten aluminum, the power output end of the lifting drive assembly 210 is at the first height, and the connection angle between the fixed groove 110 and the movable groove 120 is 180°, so that the liquid guiding direction of the fixed groove 110 and the liquid guiding direction of the movable groove 120 are on the same straight line.

[0040] When molten aluminum is not being transferred, the power output end of the lifting drive assembly 210 is located at the second height position, which is flush with the workshop floor. The support assembly 220 abuts against the bottom of the movable trough 120. The connection angle between the fixed trough 110 and the movable trough 120 is a preset angle, meaning the angle between the liquid guiding direction of the fixed trough 110 and the liquid guiding direction of the movable trough 120 is less than the preset angle. Specifically, the preset angle is less than 150°, and the height of the first height position is less than the height of the second height position.

[0041] In this embodiment, unlike the traditional method of raising the furnace body 21 to create a height difference, the aluminum liquid transfer device 10 of this disclosure lowers the transfer bag 22 through the power output end of the lifting drive component 210, thereby creating a height difference between the transfer bag 22 and the discharge port of the furnace body 21. The aluminum liquid in the furnace body 21 flows into the transfer bag 22 through the reversible flow channel 100. Therefore, it is not necessary to raise the furnace body 21 to meet the height difference required for transportation, thereby improving the convenience and safety of feeding.

[0042] Furthermore, the reversible flow channel 100 consists of a fixed channel 110 and a movable channel 120. The fixed channel 110 is fixedly connected to the furnace body 21. The movable channel 120 rotates relative to the fixed channel 110 via a rotating component 130. The support component 220, as the power output end of the lifting drive component 210 is raised, abuts against the movable channel 120 and provides support, ensuring that the movable channel 120 remains in a reversed state. This achieves the automatic reversing function of the reversible flow channel 100, allowing the movable channel to separate from the transfer package 22, facilitating the transfer and replacement of the transfer package 22 by workers, reducing the labor intensity of workers, and improving the efficiency and safety of aluminum liquid transfer.

[0043] It should be noted that the lifting drive assembly 210 falls within the scope of existing technology and will not be described in detail here.

[0044] like Figures 1 to 5 As shown, in one embodiment, the support assembly 220 includes a first support column 221 and a second support column 222. The first support column 221 is connected to the power output end of the lifting drive assembly 210, and the second support column 222 is connected to the outer peripheral wall of the first support column 221. The end of the second support column 222 away from the first support column 221 is located near the furnace body 21. A first roller 2211 is rotatably provided on the top plate of the first support column 221, and a second roller 2221 is provided at the end of the second support column 222 near the furnace body 21. It can be understood that the support assembly 220 has two rollers located in different directions, which provide support and guide the movement of the movable groove 120 during the rotation process, reducing friction between the support column and the movable groove 120, ensuring smooth operation of the rotation process of the movable groove 120, and avoiding jamming or shaking. Furthermore, the lifting support mechanism 200 realizes the automatic rotation function of the movable groove 120, simplifies the operation of rotating the movable groove 120, reduces the difficulty and labor intensity of workers, thereby improving efficiency and stability.

[0045] When the power output end of the lifting drive assembly 210 rises or falls, the support assembly 220 moves accordingly, as follows:

[0046] As the power output end of the lifting drive assembly 210 rises, the support assembly 220 and the transfer bag 22 rise along with it. The transfer bag 22 provides support, gradually lifting the movable slot 120. The connection angle between the movable slot 120 and the fixed slot 110 gradually decreases. When the power output end of the lifting drive assembly 210 rises to the third height position, the connection angle between the fixed slot 110 and the movable slot 120 is the first transition angle. The movable slot 120 separates from the transfer bag 22, and the first roller 2211 abuts against the bottom of the movable slot 120 and provides support, facilitating the replacement or movement of the transfer bag 22. When the power output end of the lifting drive assembly 210 continues to rise to the fourth height position, the connection angle between the fixed groove 110 and the movable groove 120 is the second transition angle. The first roller 2211 and the second roller 2221 both abut against the bottom of the movable groove 120 and provide support until the power output end of the lifting drive assembly 210 rises to the second height position. The angle of the connection angle between the fixed groove 110 and the movable groove 120 is the preset angle.

[0047] As the power output end of the lifting drive assembly 210 descends, the support assembly 220 and the transfer bag 22 descend along with it. The first roller 2211 and the second roller 2221 support and guide the movable groove 120 to flip downwards. When the power output end of the lifting drive assembly 210 descends to the fourth height position, the connection angle between the fixed groove 110 and the movable groove 120 is less than the second transition angle, and the movable groove 120 disengages from the second roller 2221. The first roller 2211 continues to support and guide the movable groove 120 to flip. When the power output end of the lifting drive assembly 210 descends to the second height position, the movable groove 120 disengages from the first roller 2211 and overlaps with the transfer bag 22 until the power output end of the lifting drive assembly 210 descends to the first height position, at which point the liquid guiding direction of the fixed groove 110 and the liquid guiding direction of the movable groove 120 are on the same straight line.

[0048] The first transition angle is greater than the second transition angle, and the second transition angle is greater than the preset included angle, while the first angle is less than 150°. The height positions, from highest to lowest, are the second height position, the fourth height position, the third height position, and the first height position.

[0049] like Figures 1 to 5 As shown, in one embodiment, the end of the second support column 222 is welded to the outer peripheral wall of the first support column 221. It is understood that through welding, a strong bond is formed between the second support column 222 and the first support column 221, enabling it to withstand larger loads and vibrations, ensuring the stability and reliability of the equipment during operation.

[0050] like Figures 1 to 4 As shown, in one embodiment, the rotating assembly 130 includes a connecting plate 131 and a rotating seat 132. The connecting plate 131 is provided on both side walls of the movable groove 120 adjacent to the fixed groove 110, and the rotating seat 132 is correspondingly provided on both side walls of the fixed groove 110 adjacent to the movable groove 120. The rotating seat 132 is rotatably connected to the connecting plate 131. Specifically, in this embodiment, the rotating seat 132 and the connecting plate 131 are connected by a rotating shaft 133, with both ends of the rotating shaft 133 passing through the corresponding connecting plate 131 and rotating seat 132. The rotating seat 132 supports the rotating shaft 133, ensuring smooth rotation, reducing friction, and extending service life. The rotating seat 132 and the connecting plate 131 are connected by the rotating shaft 133, enabling flexible rotation of the movable groove 120.

[0051] It should be noted that the number of rotating shafts 133 is not limited to one. For example, in other embodiments, the number of rotating shafts 133 is two, and the two rotating shafts 133 are respectively inserted through the connecting plate 131 and the rotating seat 132 on one side.

[0052] like Figures 1 to 4As shown, in one embodiment, the preset included angle ranges from 90° to 150°. Specifically, in this embodiment, when the power output end of the lifting drive assembly 210 is at the second height position, the connection angle between the fixed groove 110 and the movable groove 120 is 80°, that is, the preset included angle in this embodiment is 80°. At this time, the first roller 2211 and the second roller 2221 provide support for the movable groove 120, and the movable groove 120 does not overlap with the transfer bag 22, which facilitates the worker to transfer or replace the transfer bag 22.

[0053] like Figures 1 to 4 As shown, in one embodiment, the fixed groove 110 is provided with a first abutting slope 111 at one end near the movable groove 120, and the movable groove 120 is provided with a corresponding second abutting slope 121 at one end near the fixed groove 110.

[0054] like Figures 1 to 4 As shown, in one embodiment, the angle between the first abutting inclined surface 111 and the bottom of the fixed groove 110 ranges from 75° to 80°. It is understood that designing the first abutting inclined surface 111 and the second abutting inclined surface 121 as inclined surfaces increases the contact area of ​​the abutting surfaces, improves sealing performance, and prevents aluminum liquid leakage. The connection between the fixed groove 110 and the movable groove 120 is provided with an angle of 10° to 15°. When the movable groove 120 is pressed against the fixed groove 110, the total weight of the movable groove 120 itself can be used to tightly press it against the fixed groove 110, further improving the sealing effect between the fixed groove 110 and the movable groove 120, ensuring that the aluminum liquid does not leak during the transfer process.

[0055] Specifically, in this embodiment, the angle at the connection between the fixed groove 110 and the movable groove 120 is 10°, that is, the angle between the first contact surface and the bottom of the fixed groove 110 is 80°.

[0056] like Figures 1 to 4 As shown, in one embodiment, a sealing gasket 1111 is provided around the periphery of the end face of the first abutting inclined surface 111 facing the movable groove 120. Specifically, in this embodiment, the sealing gasket 1111 is made of refractory cotton, which has good elasticity and high temperature resistance. When the movable groove 120 and the fixed groove 110 are pressed together, it can tightly fit the abutting surface, fill the tiny gaps, prevent aluminum liquid leakage, ensure the sealing of the aluminum liquid transmission process, improve the reliability and service life of the reversible flow channel 100, and reduce safety hazards.

[0057] like Figure 1 , Figure 2 and Figure 6As shown, in one embodiment, the aluminum liquid transfer device 10 further includes a fixing component 300. The fixing component 300 includes multiple fixing members (not shown), a fixing plate 310, and a connecting seat 320. The fixing plate 310 is disposed at the end of the fixing groove 110 away from the movable groove 120. The connecting seat 320 is disposed around the liquid outlet of the furnace body 21. A connecting strip 330 is formed at the connection between the fixing plate 310 and the connecting seat 320. Multiple fixing members are spaced apart along the connecting strip 330. Specifically, in this embodiment, the connecting strip 330 is U-shaped and conforms to the shape of the flow channel. Multiple fixing holes 3301 are spaced apart on the connecting strip 330. Each fixing member passes through the corresponding fixing hole 3301 to fix the fixing groove 110 to the furnace body 21. The fixing hole 3301 is a threaded hole, and the fixing member is a bolt. The fixing groove 110 is firmly connected to the furnace body 21 by bolts to prevent the fixing groove 110 from shifting or loosening during the aluminum liquid transfer process, thus ensuring the stability and safety of the entire aluminum liquid transfer device 10.

[0058] Please see Figure 1 This disclosure also provides an aluminum smelting equipment 20, which includes a furnace body 21, a transfer bag 22, and an aluminum liquid transfer device 10 as described in any of the above embodiments.

[0059] In this embodiment, the aluminum smelting equipment 20 utilizes an aluminum molten material transfer device 10 and a transfer bag 22 to transfer the aluminum molten material within the furnace body 21. The transfer bag 22 is positioned at the power output end of the lifting drive assembly 210 of the aluminum molten material transfer device 10. As the power output end of the lifting drive assembly 210 rises and falls, the transfer bag 22 rises or falls accordingly. The transfer bag 22 can descend to a position below ground level and dock with the reversible flow channel 100, thereby completing the transfer of aluminum molten material below ground level. This avoids the traditional method of raising the furnace body 21 to meet the height difference for liquid transfer, facilitating the worker's feeding operation. Furthermore, the reversible flow channel of the aluminum molten material transfer device 10 works in conjunction with the lifting support mechanism 200 to achieve automatic rotation of the movable slot 120 of the reversible flow channel 100, simplifying the transfer and replacement process of the transfer bag 22, reducing the labor intensity of workers, and improving the efficiency and safety of aluminum molten material transfer.

[0060] Compared with the prior art, this disclosure has at least the following advantages:

[0061] Unlike traditional methods that involve raising the furnace body to create a height difference, the aluminum liquid transfer device disclosed herein lowers the transfer bag through the power output end of the lifting drive component, thereby creating a height difference between the transfer bag and the discharge port of the furnace body. The aluminum liquid inside the furnace body flows into the transfer bag through a reversible flow channel. Therefore, it is not necessary to raise the furnace body to meet the height difference required for transportation, thus improving the convenience and safety of feeding.

[0062] The reversible flow channel consists of a fixed channel and a movable channel. The fixed channel is fixedly connected to the furnace body, and the movable channel rotates relative to the fixed channel through a rotating component. The support component, as the power output end of the lifting drive component is raised, comes into contact with and supports the movable channel, ensuring that the movable channel remains in a reversed state. This realizes the automatic reversing function of the movable channel, allowing it to be separated from the transfer bag, making it easier for workers to transfer and replace the transfer bag, reducing the labor intensity of workers, and improving the efficiency and safety of aluminum liquid transfer.

[0063] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
