Description

Technical Field

[0001] This utility model relates to the technical field of batching equipment, specifically to an intelligent aluminum electrolytic cell fluoride salt constant volume feeder. Background Technology

[0002] Fluoride salts for aluminum electrolysis refer to the collective term for fluoride salts such as cryolite, aluminum fluoride, sodium fluoride, magnesium fluoride, calcium fluoride, and sodium hydroxide in industrial aluminum electrolytes. These are materials used in aluminum electrolysis, with cryolite and aluminum fluoride being the main components of industrial aluminum electrolytes. Currently, the feeding method for fluoride salts used in aluminum electrolysis is mostly based on manual weighing and volume determination.

[0003] Utility model patent CN220619141U discloses an intelligent aluminum electrolytic cell fluoride salt constant-volume feeder, belonging to the technical field of batching equipment. It addresses the problem that most existing chemical batching methods rely on manual weighing and volume determination, which is highly dependent on the accuracy of the weighing equipment and suffers from low production efficiency due to slow weighing. The device includes a batching device base plate, with a batching device mounting plate fixedly installed at the top, and a feed tank fixedly installed at the top of the mounting plate. The feed tank has an internal feed ramp, and a leak-proof piston is fixedly installed on one side of the top of the feeder mounting plate. One side of the leak-proof piston extends into the interior of the feed tank, and a feed pipe is provided at the bottom of the feed tank. This utility model, by including a feed tank, a leak-proof piston, a feed pipe, a support frame, and a feed tank, effectively solves the problem that most existing chemical feed methods rely on manual weighing and volume determination for batching. This batching method is highly dependent on the accuracy of the weighing equipment, and the slow weighing efficiency leads to low chemical production efficiency.

[0004] However, the above patent still has shortcomings: although it can control the quantitative feeding of fluoride salts for aluminum electrolysis, it does not have the function of preventing leakage. As a result, during the process of controlling the closing of the feeding pipe by the extension and retraction of the anti-leakage piston, a small amount of fluoride salts for aluminum electrolysis will continue to be discharged through the feeding pipe, which causes errors in the feeding of fluoride salts for aluminum electrolysis and makes it impractical. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intelligent aluminum electrolysis cell fluoride salt constant volume feeder, which solves the problem mentioned in the background art that although the existing intelligent aluminum electrolysis cell fluoride salt constant volume feeder can control the quantitative feeding of fluoride salt for aluminum electrolysis, it does not have the function of preventing leakage. As a result, during the process of the anti-leakage piston extending and retracting to control the closing of the feeding pipe, a small amount of fluoride salt for aluminum electrolysis will continue to be discharged through the feeding pipe, resulting in errors in the feeding of fluoride salt for aluminum electrolysis and poor practicality.

[0006] The technical solution of this utility model is:

[0007] A smart aluminum electrolytic cell fluoride salt constant volume feeder includes: a base plate; a storage box is provided on the top of the base plate, and support rods are fixedly connected to both sides of the storage box. The bottom ends of the support rods are fixedly connected to the base plate. A discharge port is opened at the center of the bottom of the storage box. A fixing ring is fixedly connected to the outer surface of the bottom end of the discharge port. A drive shaft is provided inside the discharge port. Leakage prevention mechanisms to improve the feeding accuracy are provided on both sides of the bottom of the fixing ring. An anti-clogging feeding mechanism is provided on the outer surface of the drive shaft located inside the discharge port.

[0009] Preferably, a lifting rod is fixedly connected to the top center of each lifting plate, the top end of each lifting rod passes through the mounting plate and extends to the lifting ring, the lifting ring is sleeved on the outer surface of the discharge port, the lifting rod is slidably connected to the mounting plate, the mounting plate is fixed to the outer surface of the discharge port, and two electric push rods are fixedly connected to the top of each mounting plate, the telescopic ends of each electric push rod are fixedly connected to the lifting ring.

[0010] Preferably, the feeding mechanism includes: an auger blade fixedly connected to the outer surface of the drive shaft located inside the discharge port, the auger blade being adapted to the discharge port; a rotating scraper provided on one side of the drive shaft located inside the storage bin; three connecting rods fixedly connected to the side of the rotating scraper near the drive shaft; a fixing sleeve fixedly connected to the end of each connecting rod away from the rotating scraper; the fixing sleeves being fixed to the outer surface of the drive shaft; the rotating scraper being adapted to the storage bin; the top end of the drive shaft passing through the cross and extending to the motor; the motor being fixedly connected to the cross; the cross being fixedly connected to the storage bin; and the drive shaft being fixedly connected to the output end of the motor.

[0011] Preferably, a matching rubber strip is fixedly connected to the side of the rotating scraper near the storage bin.

[0012] Preferably, a weighing sensor is fixedly connected to the bottom plate near the discharge port, and a material cylinder is provided at the top center of the weighing sensor.

[0013] Preferably, each of the four bottom corners of the base plate is fixedly connected to a caster wheel with a braking function, and a control box with an internal touch screen is fixedly connected to the side of one of the support rods away from the storage box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Firstly, this utility model, through the coordinated action of the base plate, storage box, support rod, discharge port, fixing ring, transmission shaft, and anti-leakage mechanism, can not only accurately control the metering of fluoride salts for aluminum electrolysis, but also quickly close the discharge port at the end of the feeding process, preventing a small amount of fluoride salts from continuing to be discharged. This improves the accuracy of fluoride salt feeding and solves the problem that while existing intelligent aluminum electrolysis cell fluoride salt constant volume feeders can control the quantitative feeding of fluoride salts for aluminum electrolysis, they do not have an anti-leakage function. As a result, during the process of the anti-leakage piston extending and retracting to control the closing of the feeding pipe, a small amount of fluoride salts for aluminum electrolysis continues to be discharged through the feeding pipe, causing errors in the feeding of fluoride salts for aluminum electrolysis and poor practicality.

[0016] Secondly, through the coordinated action of the base plate, storage box, support rod, discharge port, fixing ring, transmission shaft and feeding mechanism, this utility model can continuously agitate the aluminum electrolysis fluoride salt at the discharge port and scrape off the aluminum electrolysis fluoride salt adhering to the inner wall of the device while controlling the feeding of aluminum electrolysis fluoride salt. This not only avoids the aluminum electrolysis fluoride salt clogging the discharge port, but also avoids the waste caused by a small amount of aluminum electrolysis fluoride salt adhering to the inner wall of the device due to static electricity.

[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] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A smart aluminum electrolytic cell fluoride salt constant volume feeder includes: a base plate 1; a storage tank 2 is provided on the top of the base plate 1, and support rods 3 are fixedly connected to both sides of the storage tank 2. The bottom ends of the support rods 3 are fixedly connected to the base plate 1. A discharge port 4 is opened at the center of the bottom of the storage tank 2. A fixing ring 5 is fixedly connected to the outer surface of the bottom end of the discharge port 4. A drive shaft 6 is provided inside the discharge port 4. Leakage prevention mechanisms 7 are provided on both sides of the bottom of the fixing ring 5 to improve the accuracy of feeding. A clogging-preventing feeding mechanism 8 is provided on the outer surface of the drive shaft 6 located inside the discharge port 4. The user pours aluminum electrolytic cell fluoride salt into the storage tank 2, and then controls the leak prevention mechanism 7 and the feeding mechanism 8 to open, so that the aluminum electrolytic cell fluoride salt inside the storage tank 2 can be discharged through the discharge port 4 to achieve the function of quantitative feeding. After feeding is completed, the leak prevention mechanism 7 and the feeding mechanism 8 can be closed.

[0028] like Figure 4 and Figure 5As shown, the leak-proof mechanism 7 includes: opening and closing hoppers 9 are provided on both sides of the bottom of the fixing ring 5; first fixing blocks 10 are fixedly connected to the top of the two opening and closing hoppers 9 on both sides; first rotating shafts 11 are rotatably connected inside the first fixing blocks 10; the ends of the first rotating shafts 11 away from the first fixing blocks 10 are fixedly connected to the fixing ring 5; second fixing blocks 12 are fixedly connected to the opposite sides of the two first fixing blocks 10; second rotating shafts 13 are fixedly connected inside the second fixing blocks 12; the ends of the second rotating shafts 13 away from the second fixing blocks 12 pass through the lifting plate 14 and extend to the limiting block 15; the limiting block 15 is divided into... The lifting plate 14 is fixedly connected to the second rotating shaft 13. Each lifting plate 14 is provided with a matching stroke groove 16 near the second rotating shaft 13. When the lifting plate 14 rises, it pulls the second rotating shaft 13 through the stroke groove 16. The second rotating shaft 13 drives the second fixed block 12, and the second fixed block 12 drives the first fixed block 10, so that the first fixed block 10 rotates around the first rotating shaft 11. When the first fixed block 10 rotates, it drives the opening and closing hopper 9, thereby controlling the two opening and closing hoppers 9 at the bottom of the discharge port 4 to rotate and open to both sides at the same time. After the material is discharged, the lifting plate 14 is controlled to move downward, which can control the two opening and closing hoppers 9 to close.

[0029] like Figure 4 As shown, a lifting rod 17 is fixedly connected to the top center of the lifting plate 14. The top of the lifting rod 17 passes through the mounting plate 18 and extends to the lifting ring 19. The lifting ring 19 is sleeved on the outer surface of the discharge port 4. The lifting rod 17 is slidably connected to the mounting plate 18. The mounting plate 18 is fixed to the outer surface of the discharge port 4. Two electric push rods 20 are fixedly connected to the top of the mounting plate 18. The telescopic ends of the electric push rods 20 are fixedly connected to the lifting ring 19. When the electric push rods 20 are started, the telescopic ends of the electric push rods 20 extend and retract, driving the lifting ring 19 to move vertically up and down on the outer surface of the discharge port 4. While the lifting ring 19 is moving up and down, it drives the lifting rod 17. The lifting rod 17 drives the lifting plate 14, thereby achieving the purpose of controlling the lifting plate 14 to move up and down.

[0030] like Figure 6As shown, the feeding mechanism 8 includes: an auger blade 21 fixedly connected to the outer surface of the drive shaft 6 located inside the discharge port 4, the auger blade 21 being adapted to the discharge port 4; a rotating scraper 22 provided on one side of the drive shaft 6 located inside the storage tank 2; three connecting rods 23 fixedly connected to the side of the rotating scraper 22 near the drive shaft 6; a fixing sleeve 24 fixedly connected to the end of each connecting rod 23 away from the rotating scraper 22; the fixing sleeves 24 being fixed to the outer surface of the drive shaft 6; the rotating scraper 22 being adapted to the storage tank 2; the top end of the drive shaft 6 passing through the cross 25 and extending to the motor 26; the motor 26 being fixedly connected to the cross 25; the cross 25 being fixedly connected to the storage tank 2; and the drive shaft 6 being... The output end of motor 26 is fixedly connected. When motor 26 is started, the output end of motor 26 drives transmission shaft 6. While transmission shaft 6 rotates, it drives fixed sleeve 24 and auger blade 21. While auger blade 21 rotates, it discharges the aluminum electrolytic cell fluoride salt inside storage tank 2 through discharge port 4. While fixed sleeve 24 rotates, it drives connecting rod 23. Connecting rod 23 drives rotating scraper 22, thereby causing connecting rod 23 and rotating scraper 22 to rotate around transmission shaft 6 inside storage tank 2. While rotating, connecting rod 23 and rotating scraper 22 continuously scrape off the aluminum electrolytic cell fluoride salt adhering to the inside of storage tank 2, and can also continuously agitate the aluminum electrolytic cell fluoride salt at discharge port 4.

[0031] like Figure 3 As shown, a matching rubber strip 27 is fixedly connected to the side of the rotating scraper 22 near the storage bin 2, which can protect the inner wall of the storage bin 2 and prevent the rotating scraper 22 from scratching the inner wall of the storage bin 2.

[0032] like Figure 1 and Figure 2 As shown, a weighing sensor 28 is fixedly connected to the bottom plate 1 near the discharge port 4. A material cylinder 29 is set at the top center of the weighing sensor 28. The discharged aluminum electrolytic cell fluoride salt enters the interior of the material cylinder 29. The weighing sensor 28 measures the aluminum electrolytic cell fluoride salt inside the material cylinder 29. When the aluminum electrolytic cell fluoride salt inside the material cylinder 29 reaches the set threshold, the control motor 26 is turned off and the telescopic end of the electric push rod 20 is retracted.

[0033] like Figure 1 As shown, the bottom four corners of the base plate 1 are all fixedly connected with casters 30 with braking function. One of the support rods 3 is fixedly connected to a control box 31 with an internal touch screen on the side away from the storage box 2. The casters 30 can facilitate the user to move and fix the device, and the control box 31 can facilitate the user to operate the device.

[0034] Working principle: The user pours the fluoride salt from the aluminum electrolysis cell into the storage tank 2, then starts the motor 26 and controls the extension end of the electric push rod 20 to extend outward. Simultaneously, the extension end of the electric push rod 20 controls the lifting ring 19 to move upward. The lifting ring 19 drives the lifting plate 14 via the lifting rod 17. As the lifting plate 14 rises, it pulls the second rotating shaft 13 via the stroke groove 16. The second rotating shaft 13 drives the second fixed block 12, which in turn drives the first fixed block 10, causing the first fixed block 10 to rotate around the first rotating shaft 11. While rotating, the motor drives the opening and closing hopper 9, thereby controlling the two opening and closing hoppers 9 at the bottom of the discharge port 4 to rotate and open to both sides simultaneously. At the same time, the output end of the motor 26 drives the transmission shaft 6. As the transmission shaft 6 rotates, it drives the fixed sleeve 24 and the auger blades 21. As the auger blades 21 rotate, they discharge the aluminum electrolytic cell fluoride salt inside the storage tank 2 through the discharge port 4. While the fixed sleeve 24 rotates, it drives the connecting rod 23. The connecting rod 23 drives the rotating scraper 22, thereby causing the connecting rod 23 and the rotating scraper 22 to rotate around the transmission shaft 6 inside the storage tank 2. 3. Simultaneously, the rotating scraper 22 continuously scrapes off the aluminum electrolytic cell fluoride salt adhering to the inside of the storage tank 2, and also continuously agitates the aluminum electrolytic cell fluoride salt at the discharge port 4, thereby conveying the aluminum electrolytic cell fluoride salt into the material cylinder 29. The weighing sensor 28 measures the amount of aluminum electrolytic cell fluoride salt inside the material cylinder 29. When the amount of aluminum electrolytic cell fluoride salt inside the material cylinder 29 reaches the set threshold, the control box 31 controls the motor 26 to shut down and the telescopic end of the electric push rod 20 to retract, thereby controlling the lifting plate 14 to move downwards, thus controlling the closure of the two opening and closing hoppers 9. Not only can it accurately control the metering of fluoride salts used in aluminum electrolysis, but it can also quickly close the outlet 4 at the end of the feeding process to prevent a small amount of fluoride salts from continuing to be discharged. This improves the accuracy of fluoride salt feeding and solves the problem that while existing intelligent aluminum electrolysis cell fluoride salt constant volume feeders can control the quantitative feeding of fluoride salts, they do not have a leakage prevention function. This causes a small amount of fluoride salts to continue to be discharged through the feeding pipe during the process of the leakage prevention piston extending and retracting to control the closing of the feeding pipe, resulting in errors in the feeding of fluoride salts and poor practicality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
