Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid flow channel technology, specifically an emergency treatment device for aluminum liquid flow channels. Background Technology

[0002] As the core channel for transporting high-temperature molten aluminum in the aluminum smelting process, the aluminum molten flow channel plays a crucial role in conveying the high-temperature molten aluminum from the electrolytic cell to subsequent casting and processing steps. During operation, it must continuously withstand the scouring of high-temperature molten aluminum at around 1000℃, and is also subject to chemical corrosion from media such as molten salt and alumina dust. Therefore, stringent requirements are placed on its structural strength, corrosion resistance, and thermal insulation performance.

[0003] In actual operation, existing aluminum molten flow channels often require manual intervention to plug leaks or repairs in emergency situations such as sudden leaks or localized structural damage. This method is not only inefficient but also poses safety hazards such as burns and molten aluminum splashing, which can easily lead to personal injury and equipment damage. It fails to meet the demands of modern aluminum smelting production for safety and timely emergency response. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an emergency treatment device for aluminum liquid flow channels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency treatment device for aluminum liquid flow channels, comprising a support plate, a channel steel plate fixedly connected to the top of the support plate, a connecting rod fixedly connected to the side wall of the support plate, a guide rail fixedly connected to one end of the connecting rod, the outer surface of the guide rail slidingly contacting an emergency treatment component, an angle plate fixedly connected to the other side wall of the support plate, a rotating shaft rotatably connected inside the angle plate, a sprocket fixedly connected to one end of the rotating shaft, a chain meshing with the sprocket, and a crank fixedly connected to the other end of the rotating shaft;

[0006] The emergency treatment component includes a movable plate, with a C-shaped frame connected to its side by through bolts. Rollers are rotatably connected to the outer surface of the C-shaped frame. A sealing disc is placed on the top surface of the movable plate, and a top rod is fixedly connected to the center of the bottom surface of the sealing disc. A base plate is connected to the bottom end of the top rod by screws. The lower surface of the base plate abuts against a sliding wheel, the bottom end of the sliding wheel abuts against a spring, and the outer surface of the sliding wheel slides in contact with a locking rod. A sleeve is bolted to the lower surface of the movable plate, and an L-shaped plate is fixedly connected to the lower surface of the movable plate. A chain is bolted to the outer surface of the L-shaped plate.

[0007] As described above, a number of support plates are welded at equal intervals on the lower surface of the channel steel plate, and a flow channel shell is welded on the side wall of the channel steel plate, with a ceramic flow channel attached to the inside of the flow channel shell.

[0008] As described above, both the upper and lower surfaces of the guide rail are provided with grooves, and rollers are in rolling contact within both grooves.

[0009] As described above, a chain is clamped between the L-shaped plate and the chain buckle, and the chain is engaged with two sprockets.

[0010] As described above, a push rod is inserted inside the sleeve, and a vertical groove is formed through the outer wall of the sleeve. A slider is fixedly connected to the side of the base plate, and the slider slides in contact with the vertical groove.

[0011] As described above, the bottom end of the spring abuts against the inner bottom surface of the sleeve, and the top end of the spring abuts against the bottom of the sliding wheel bracket. A through hole is provided on the outer wall of the sleeve, and a locking rod is inserted into the through hole.

[0012] As described above, one end of the locking rod is fixedly connected to a collar, and fireproof putty is placed on the top surface of the sealing plate.

[0013] Compared with existing technologies, this emergency treatment device for aluminum liquid flow channels has the following advantages:

[0014] I. When the emergency treatment component of this utility model reaches below the leak point, the locking rod is pulled out, causing the spring to reset and drive the sealing plate to move upward. The vertical groove slider structure of the top rod and the sleeve ensures stable movement direction, making the sealing plate tightly fit the leak point. The high temperature resistance of the fireproof putty on the top surface is used to fill the gap. Rapid sealing can be completed without direct manual contact with the high temperature area, effectively preventing aluminum liquid leakage, reducing the risk of personnel casualties and equipment damage, and meeting the safety and emergency treatment needs of modern aluminum smelting production.

[0015] Second, this utility model forms a stable support system through a support plate, channel steel plate and connecting rod. It not only ensures the normal transportation of aluminum liquid through the high temperature and corrosion resistance of the ceramic flow channel, but also uses the guide rail and sprocket chain transmission structure to enable the emergency treatment component to be quickly moved to the leak location by a crank. The cooperation of the guide rail and roller ensures smooth and precise movement, buys time for emergency sealing, avoids the safety hazards of close-range manual operation, and improves the timeliness of emergency response.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-7 As shown, this utility model provides a technical solution: an emergency treatment device for aluminum liquid flow channels, including a support plate 1, a channel steel plate 2 fixedly connected to the top of the support plate 1, a connecting rod 3 fixedly connected to the side wall of the support plate 1, a guide rail 4 fixedly connected to one end of the connecting rod 3, an emergency treatment component 5 slidingly contacting the outer surface of the guide rail 4, an angle plate 6 fixedly connected to the other side wall of the support plate 1, a rotating shaft 7 rotatably connected inside the angle plate 6, a sprocket 8 fixedly connected to one end of the rotating shaft 7, a chain 9 meshing with the sprocket 8, and a crank handle 10 fixedly connected to the other end of the rotating shaft 7;

[0027] The emergency handling component 5 includes a movable plate 51, with a C-shaped frame 52 connected to the side of the movable plate 51 by through bolts. A roller 53 is rotatably connected to the outer surface of the C-shaped frame 52. A sealing plate 54 is placed on the top surface of the movable plate 51. A top rod 55 is fixedly connected to the center of the bottom surface of the sealing plate 54. A base plate 56 is connected to the bottom end of the top rod 55 by screws. The lower surface of the base plate 56 abuts against a sliding wheel 57. The bottom end of the sliding wheel 57 abuts against a spring 58. The outer surface of the sliding wheel 57 slides in contact with a locking rod 59. A sleeve 510 is bolted to the lower surface of the movable plate 51, and an L-shaped plate 511 is fixedly connected to the lower surface of the movable plate 51. A chain buckle 512 is bolted to the outer surface of the L-shaped plate 511.

[0028] like Figure 1 and Figure 2 As shown, several support plates 1 are welded at equal intervals on the lower surface of the channel steel plate 2, and a flow channel shell 11 is welded on the side wall of the channel steel plate 2. A ceramic flow channel 12 is attached to the inside of the flow channel shell 11.

[0029] By setting up the support plate 1 in conjunction with the channel steel plate 2 to support the outer shell 11 of the flow channel, a stable support structure can be formed to ensure the structural stability of the outer shell 11 and the internal ceramic flow channel 12 during the process of conveying high-temperature aluminum liquid. The outer surface of the ceramic flow channel 12 is wrapped with the outer shell 11, which can enhance the overall protection. The high temperature resistance and corrosion resistance of the ceramic flow channel 12 can directly withstand the scouring of aluminum liquid and the corrosion of chemical media, ensuring the safe transportation of aluminum liquid. The connecting rod 3 fixedly connected to the side of the support plate 1 can securely install the guide rail 4 under the outer shell 11 of the flow channel, providing a sliding track for the emergency treatment component 5.

[0030] like Figure 3 As shown, the upper and lower surfaces of the guide rail 4 are provided with grooves, and rollers 53 are in rolling contact in both grooves.

[0031] A chain 9 is clamped between the L-shaped plate 511 and the chain buckle 512, and the chain 9 is engaged with two sprockets 8.

[0032] When the ceramic flow channel 12 and the flow channel housing 11 leak unexpectedly, on-site personnel can immediately rotate the crank handle 10 to drive the rotating shaft 7 and sprocket 8 to rotate. The sprocket 8 engages with the chain 9 for transmission. Since the chain 9 is clamped between the L-shaped plate 511 and the chain buckle 512 of the emergency treatment component 5, it drives the moving plate 51 to slide along the guide rail 4. The grooves on the upper and lower surfaces of the guide rail 4 cooperate with the rollers 53 to ensure the smoothness and guidance of the moving plate 51, so that the emergency treatment component 5 can move quickly and accurately to the leak location, buying time for subsequent sealing operations.

[0033] like Figures 4-7As shown, a push rod 55 is inserted inside the sleeve 510, and a vertical groove 513 is provided through the outer wall of the sleeve 510. A slider is fixedly connected to the side of the base plate 56, and the slider slides in contact with the vertical groove 513.

[0034] The bottom end of the spring 58 abuts against the inner bottom surface of the sleeve 510, and the top end of the spring 58 abuts against the bottom of the sliding wheel 57 bracket. A through hole is provided on the outer wall of the sleeve 510, and a locking rod 59 is inserted into the through hole.

[0035] One end of the locking rod 59 is fixedly connected to a collar, and fireproof putty is placed on the top surface of the sealing plate 54.

[0036] Once the sealing disc 54 is positioned below the leak point, a hook or similar tool is used to hook the collar at one end of the locking rod 59. Pulling the collar causes the locking rod 59 to be pulled out of the sleeve 510. After the locking rod 59 is pulled out of the sleeve 510, the spring 58 loses its limiting effect and returns to its original deformation, pushing the sliding wheel 57 and the base plate 56 upward. This causes the top rod 55 and the sealing disc 54 to move upward, making the sealing disc 54 tightly fit below the leak point. At the same time, as the top rod 55 moves upward within the sleeve 510, the slider of the base plate 56 slides along the vertical groove 513, ensuring the stability of the top rod 55's movement direction. Finally, the fireproof putty on the top surface of the sealing disc 54 fills the leak gap, achieving rapid sealing of the leak point. This process, driven by the elastic reset of the spring 58, precisely positions the sealing disc 54. Combined with the high-temperature resistance of the fireproof putty, it can temporarily and effectively prevent aluminum liquid leakage, allowing for immediate shutdown and maintenance.

[0037] Working principle: First, when the ceramic flow channel 12 and the flow channel shell 11 leak, the crank handle 10 is turned to drive the rotating shaft 7 and sprocket 8 to rotate. The moving plate 51 is driven to slide along the guide rail 4 through the chain 9. With the cooperation of the guide rail 4 and the roller 53, the emergency treatment component 5 can be moved quickly and accurately to the leak position. After the sealing plate 54 is below the leak point, the locking rod 59 is hooked with a tool to pull it out of the sleeve 510. The spring 58 returns to its original shape and pushes the sliding wheel 57, the base plate 56, the top rod 55 and the sealing plate 54 to move upward, so that the sealing plate 54 fits tightly against the area below the leak point. At the same time, the slider of the base plate 56 slides along the vertical groove 513 to ensure stable movement. Finally, the fireproof putty on the top surface of the sealing plate 54 is used to fill the leak gap. After the rapid sealing is completed, subsequent shutdown maintenance can be carried out.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
