Description

Technical Field

[0001] This invention relates to the field of alumina powder transportation technology, specifically to a material anti-clogging addition device for aluminum ingot production. Background Technology

[0002] In aluminum ingot production, the alumina powder screw conveyor is a core piece of equipment connecting the raw material processing and electrolytic smelting processes. Its core function is to achieve safe and efficient transportation of alumina powder through mechanical structure, and to solve process problems such as dust diffusion and material agglomeration. The screw blades are made of wear-resistant metal with a special surface treatment to reduce material adhesion. By rotating, the alumina powder is propelled along a fixed path. When the screw blades rotate, the alumina powder is driven forward by the thrust of the blades, forming a continuous material flow. The conveying speed can be controlled by adjusting the rotation speed to meet the production rhythm requirements, realizing the automated transportation of alumina powder from the storage silo to the electrolytic cell, avoiding the interruption and error of manual feeding, and ensuring the stable operation of the smelting process.

[0003] In aluminum ingot production, alumina powder is transported via a screw conveyor. The screw conveyor pushes the alumina powder through rotating helical blades. The existing helical blades have a spiral ring on their outer surface, which causes friction during the process of pushing the alumina powder. The continuous spiral surface of the ring blades repeatedly rubs against the alumina powder particles, causing an imbalance of surface charge on the particles. The repulsion of like charges should disperse the powder, but in a dry environment, static electricity is difficult to dissipate. Instead, weak electrostatic attraction causes the particles to form loose agglomerates. While the ring structure of the helical blades generates axial thrust on the powder during rotation, the small gap between the blade edge and the pipe wall causes the powder to be strongly compressed. The agglomerates are gradually compacted under mechanical pressure, forming hard lumps. These lumps accumulate at bends or diameter changes in the conveyor, and due to electrostatic effects, they further adhere, eventually forming a stable arch bridge structure that completely blocks the pipeline, causing production interruption. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing screw conveyors used in aluminum ingot production that generate static electricity, leading to agglomeration and bridging and causing blockages, this invention provides a material anti-blocking and adding device for aluminum ingot production.

[0006] Technical solution

[0007] To achieve the goal of reducing static electricity generation and rapidly discharging generated static electricity during the conveying of alumina powder materials in aluminum ingot production using a screw conveyor, the present invention achieves this through the following technical solution: a material anti-clogging and adding device for aluminum ingot production, comprising a screw conveyor, wherein the screw conveyor is provided with a housing, the housing has a material trough inside, a feeding assembly is installed inside the screw conveyor, an infeed assembly is installed on the outer surface of the screw conveyor, a spiral blade is installed on the outer surface of the feeding assembly, and a plurality of angle deflection assemblies are installed inside the spiral blade;

[0008] The angle deflection assembly includes a blade cavity and a motor. The blade cavity is located inside the helical blade. The motor is installed inside the blade cavity. A rotating shaft is installed on the outer surface of the output end of the motor. A main sprocket is installed on the outer surface of the rotating shaft. Several rotating columns are evenly and movably installed inside the helical blade. A driven sprocket is installed on one end surface of each of the rotating columns. An arc-shaped chain cover is installed inside the blade cavity. Two snap-fit ​​components are installed on the outer surface of each of the rotating columns. A blade deflector is movably installed on the other end surface of each of the rotating columns. The end face of each blade deflector has a rounded surface.

[0009] The screw conveyor is equipped with a conductive component. The angle deflection component is used to change the angle of the blades, thereby facilitating the change of the spacing between several blades. This reduces the static electricity generated by the alumina powder during the conveying process and also facilitates the change of the structural contact between different surfaces of the blades and the conductive component for conductivity.

[0010] Furthermore, the snap-fit ​​assembly includes a groove and a second rotating column. The groove is formed on the outer surface of the first rotating column, and the second rotating column is movably installed on the inner wall of the groove. A locking plate is installed on the outer surface of the second rotating column, and a movable column is installed on the bottom surface of the locking plate.

[0011] Furthermore, the rotating column has an internal telescopic groove, and a spring is movably installed on the inner wall of the telescopic groove. One end of the spring is fixedly connected to one end of the movable column, and the outer surface of the movable column is in contact with the inner wall of the telescopic groove.

[0012] Furthermore, two threaded grooves are evenly distributed on the outer surface of the blade plate, and threaded pins are movably installed on the inner walls of the two threaded grooves. The outer surface of the threaded pins is in contact with the outer surface of the clamping plate.

[0013] Furthermore, the feeding assembly includes a second motor and a first rotating shaft. The second motor is mounted on the outer surface of the housing, and the first rotating shaft is mounted on the outer surface of the output end of the second motor. Feeding baffles are evenly distributed on the outer surface of the first rotating shaft.

[0014] Furthermore, the feeding assembly includes a motor and a screw shaft. The motor is mounted on the outer surface of the housing, and the screw shaft is mounted on the outer surface of the output end of the motor. The outer surface of the screw shaft is fixedly connected to the inner surface of the screw blades.

[0015] Furthermore, the conductive component includes three wires, wire one and wire two. The three wires one are installed on the outer surface of the housing, and the three wires two are installed on the outer surface of the housing. One end of the wire two is fixedly connected to the outer surface of the screw shaft bearing seat. A grounding chain is installed on the outer surface of the housing. A carbon fiber conductive brush is installed inside the material trough. A wire three is installed on the outer surface of the carbon fiber conductive brush. The outer surface of the carbon fiber conductive brush is in movable contact with the outer surface of the blade plate. Beneficial effects

[0016] The present invention has the following beneficial effects:

[0017] 1. This material anti-clogging and adding device for aluminum ingot production helps alumina powder flow smoothly within the screw conveyor by adjusting the angle of the blades, reducing the risk of accumulation and blockage. It ensures that the alumina powder is pushed evenly and continuously, avoiding local overload. Adjusting the blade angle changes the contact pattern between the alumina powder and the blades, thereby reducing wear on the blades and the inner wall of the screw conveyor, further reducing static electricity generation. The working angle of the blades is adjusted according to the real-time flow rate, velocity, and accumulation of the alumina powder, thereby optimizing the distribution of the alumina powder between the screw blades and avoiding local overload or idling. The blade angle at the corresponding position is adjusted in real time, and the accumulation is dispersed by changing the pushing direction or speed, while maintaining the overall balance of the conveying flow, reducing the risk of blockage. Adjusting the blade angle changes the contact mode between the alumina powder and the trough, avoiding continuous high-speed friction of the alumina powder in local areas. Combined with the carbon fiber conductive brush and the three-grounded wire, static electricity is discharged, reducing the overall static electricity accumulation and further ensuring safe production.

[0018] 2. This material anti-clogging and adding device for aluminum ingot production utilizes the angle deflection of the blades, while the spiral blades drive several blades to rotate, causing different surfaces of the blades to contact the carbon fiber conductive brushes. This discharges static electricity from the blade surfaces. The static electricity generated by the spiral blades is also discharged through the second wire of the spiral shaft bearing seat. During rotation, different surfaces of the blades sequentially contact the carbon fiber conductive brushes, ensuring continuous and effective discharge of static electricity from the blade surfaces. This prevents the accumulation of static electricity on the blade surfaces, avoiding the formation of powder accumulation or agglomeration of alumina powder, which could lead to chute blockage and unstable flow. The device not only handles the static electricity on the blade surfaces but also discharges the static electricity generated by the spiral blades through the second wire of the spiral shaft bearing seat, minimizing the accumulation of static electricity throughout the conveying system and thus reducing the safety risks caused by static electricity.

[0019] 3. The material anti-clogging addition device for aluminum ingot production has arc-shaped surfaces on the end faces of the blades. These arc-shaped surfaces reduce the contact area between the blades and the alumina powder, making the contact more point-like or line-like, thus reducing the coefficient of friction. The shape of the arc-shaped surfaces helps the alumina powder slide more smoothly when it comes into contact with the blades, reducing the retention and accumulation of alumina powder on the surface of the blades, further reducing friction. Reducing friction between the blades and the alumina powder can reduce the speed and amount of charge transfer. Reduced friction means fewer opportunities for electron transfer, thus reducing the accumulation of static electricity. The arc-shaped surfaces help the alumina powder to be distributed more evenly during the conveying process and reduce accumulation on the end faces of the blades, which helps maintain the continuity of the conveying process and avoids problems such as blockage and unstable flow.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0035] Please see Figures 1-11 The present invention provides a technical solution: a material anti-clogging addition device for aluminum ingot production, including a screw conveyor 1, a housing 101 inside the screw conveyor 1, a material trough 102 inside the housing 101, a feeding assembly 103 inside the screw conveyor 1, an infeed assembly 2 on the outer surface of the screw conveyor 1, a spiral blade 1033 on the outer surface of the feeding assembly 103, and a plurality of angle deflection assemblies 3 inside the spiral blade 1033;

[0036] The angle deflection assembly 3 includes a blade cavity 301 and a motor 302. The blade cavity 301 is opened inside the spiral blade 1033. The motor 302 is installed inside the blade cavity 301. A rotating shaft 2 303 is installed on the outer surface of the output end of the motor 302. A main sprocket 304 is installed on the outer surface of the rotating shaft 2 303. Several rotating columns 1 307 are evenly and movably installed inside the spiral blade 1033. A sprocket 305 is installed on one end surface of each of the rotating columns 1 307. An arc-shaped chain cover 306 is installed inside the blade cavity 301. Two snap-fit ​​components 4 are installed on the outer surface of each of the rotating columns 1 307. A blade deflector plate 308 is movably installed on the other end surface of each of the rotating columns 1 307. An arc surface 309 is provided on the end face of each of the blade deflector plates 308.

[0037] The screw conveyor 1 is internally equipped with a conductive component 5. An angle deflection component 3 is used to change the angle of the blades 308, thereby facilitating changes in the spacing between several blades 308. This reduces static electricity generated between the blades and alumina powder during conveying and also facilitates changes in the structural contact between different surfaces of the blades 308 and the conductive component 5 for conductivity. The arc surface 309 reduces the contact area between the blades 308 and the alumina powder. Compared to a planar design, the contact area between the arc surface 309 and the alumina powder is more point-like or linear, thus reducing the coefficient of friction. The shape of the arc surface 309 helps the alumina powder slide more smoothly when contacting the blades 308, rather than generating static electricity as with a planar surface. The increased resistance reduces the retention and accumulation of alumina powder on the surface of the blade 308, further reducing friction. By reducing friction between the blade 308 and the alumina powder, the speed and amount of charge transfer can be reduced. Reduced friction means fewer opportunities for electron transfer, thus reducing static electricity accumulation. The arc surface 309 helps the alumina powder to be distributed more evenly during conveying and reduces accumulation on the end face of the blade 308. Due to the shape of the arc surface 309, the powder is more easily guided to the conveying direction of the spiral blade 1033 when it comes into contact with the blade 308, rather than remaining on the end face of the blade 308, which helps maintain the continuity of the conveying process and avoids... To address issues of blockage and unstable flow, a suitable angle for the blade 308 helps alumina powder flow smoothly within the screw conveyor 1, reducing the risk of accumulation and blockage. This ensures that the alumina powder is pushed evenly and continuously, avoiding localized overload. Adjusting the angle of the blade 308 changes the contact pattern between the alumina powder and the blade 308, thereby reducing wear on the blade 308 and the inner wall of the screw conveyor 1, further reducing static electricity generation. This allows the screw conveyor 1 to better adapt to alumina powders of different particle sizes and densities. By adjusting the working angle of the blade 308 according to the real-time flow rate, velocity, and accumulation of the alumina powder, the flow of alumina powder within the screw conveyor can be optimized. The distribution of blades 1033 prevents local overload or idling. The angle deflection of the blade plate 308 can actively intervene in the flow trajectory of alumina powder. When an alumina powder accumulation trend is detected in a certain area, the angle of the corresponding blade plate 308 is adjusted in real time. By changing the pushing direction or speed, the accumulation is dispersed, while maintaining the balance of the overall conveying flow and reducing the risk of blockage. The adjustment of the angle of the blade plate 308 can change the contact mode between alumina powder and the feed trough 102. By avoiding continuous high-speed friction of alumina powder in local areas, and with the help of the carbon fiber conductive brush 504 and the grounding of the wire 503, static electricity is discharged, reducing the overall static electricity accumulation and further ensuring safe production.

[0038] The snap-fit ​​assembly 4 includes a groove 401 and a second rotating column 402. The groove 401 is formed on the outer surface of the first rotating column 307. The second rotating column 402 is movably installed on the inner wall of the groove 401. A retaining plate 403 is installed on the outer surface of the second rotating column 402. A movable column 404 is installed on the bottom surface of the retaining plate 403. A telescopic groove 406 is formed inside the first rotating column 307. A spring 405 is movably installed on the inner wall of the telescopic groove 406. One end of the spring 405 is fixedly connected to one end of the movable column 404. The outer surface of the movable column 404 is in contact with the inner wall of the telescopic groove 406. Two threaded grooves 6 are evenly distributed on the outer surface of the blade plate 308. Threaded pins are movably installed on the inner walls of both threaded grooves 6. 7. The outer surface of the threaded nail 7 is in active contact with the outer surface of the clamping plate 403. The clamping plate 403 drives the rotating column 402 to deflect at an angle, thereby moving the clamping plate 403 into the column groove 401. At this time, the movable column 404 moves into the telescopic groove 406 and simultaneously squeezes the spring 405, thereby facilitating the separation of the rotating column 307 from the blade plate 308, thus facilitating the replacement of the blade plate 308. When installing the blade plate 308, it is only necessary to insert the blade plate 308 into the outside of the rotating column 307. The spring 405 has elastic deformation, thereby causing the clamping plate 403 to engage in the blade plate 308, thus allowing the blade plate 308 to be movably engaged in the outside of the rotating column 307, thereby facilitating the maintenance and replacement of the blade plate 308.

[0039] The feeding assembly 2 includes a second motor 201 and a first rotating shaft 202. The second motor 201 is mounted on the outer surface of the housing 101. The first rotating shaft 202 is mounted on the outer surface of the output end of the second motor 201. Feeding baffles 203 are evenly distributed on the outer surface of the first rotating shaft 202. The second motor 201 drives the first rotating shaft 202 to rotate, and the first rotating shaft 202 drives several feeding baffles 203 to rotate, thereby slowing down the entry of alumina powder into the feed trough 102 of the screw conveyor 1. A wire 501 is installed on the outer side of the housing 101 outside the feeding baffles 203 to facilitate the discharge of static electricity generated between the feeding baffles 203 and the alumina powder. During rotation, the feeding baffles 203 can slow down the entry of alumina powder into the screw conveyor 1. The speed of the feed trough 102 is adjusted by the rotation speed of motor 201 to easily control the inflow of alumina powder, thereby avoiding overload of the feed trough 102 or blockage of alumina powder. The wire 501 is installed on the outer side of the feed plate 203 on the housing 101. The function of the wire 501 is to discharge the static electricity generated between the feed plate 203 and the alumina powder. When the alumina powder rubs against the feed plate 203, static electricity is generated. If the static electricity is not discharged in time, the static electricity will cause the alumina powder to be adsorbed on the inner wall of the housing 101 or the feed plate 203, causing blockage or unstable flow, affecting production efficiency. The wire 501 is connected to the housing 101 and then conducts the static electricity to the grounding system through the grounding chain 505, thereby ensuring that the static electricity can be discharged safely and quickly.

[0040] The feeding assembly 103 includes a motor 1031 and a screw shaft 1032. The motor 1031 is mounted on the outer surface of the housing 101. The screw shaft 1032 is mounted on the outer surface of the output end of the motor 1031. The outer surface of the screw shaft 1032 is fixedly connected to the inner surface of the screw blades 1033. The motor 1031 drives the screw shaft 1032 to rotate. The screw shaft 1032 drives the screw blades 1033 to rotate. The screw blades 1033 drive several blades 308 to rotate, thereby feeding alumina powder.

[0041] The conductive component 5 includes three wires 501 and two wires 502. Wires 501 are mounted on the outer surface of the housing 101, and wires 502 are also mounted on the outer surface of the housing 101. One end of wire 502 is fixedly connected to the outer surface of the bearing seat of the screw shaft 1032. A grounding chain 505 is mounted on the outer surface of the housing 101. A carbon fiber conductive brush 504 is installed inside the feed trough 102. A wire 503 is mounted on the outer surface of the carbon fiber conductive brush 504. The outer surface of the carbon fiber conductive brush 504 is in active contact with the outer surface of the blade plate 308. The screw blade 1033 drives several blade plates 308 to rotate, causing different surfaces of the blade plates 308 to contact the carbon fiber conductive brush 504, thereby moving the blade plates 308... The static electricity generated on the surface of the blade 1033 is discharged through the second wire 502 of the bearing seat of the spiral shaft 1032. During the rotation of the blade plate 308, different surfaces of the blade plate 308 will come into contact with the carbon fiber conductive brush 504 in sequence, ensuring that the static electricity on the surface of the blade plate 308 can be continuously and effectively discharged, avoiding the accumulation of static electricity on the surface of the blade plate 308, and preventing alumina powder from forming powder accumulation or agglomeration on the surface of the blade plate 308, which would lead to blockage of the trough 102 and unstable flow. It not only deals with the static electricity on the surface of the blade plate 308, but also discharges the static electricity generated by the spiral blade 1033 through the second wire 502 of the bearing seat of the spiral shaft 1032, minimizing the accumulation of static electricity in the entire conveying system, thereby reducing the safety risks caused by static electricity.

[0042] The workflow of this invention is as follows: Alumina powder is fed into the feed trough 102 through a pipeline. The alumina powder first passes through the feeding assembly 2 and then enters the feeding assembly 103. The operation is controlled by motor 1031 and motor 201. Motor 201 drives rotating shaft 202 to rotate, which in turn drives several feed baffles 203 to rotate, thereby slowing down the entry of alumina powder into the feed trough 102 of the screw conveyor 1. A wire 501 is installed on the outer side of the outer casing 101 of the feed baffles 203 to facilitate the discharge of static electricity generated between the feed baffles 203 and the alumina powder. During rotation, the feed baffles 203 can slow down the speed at which alumina powder enters the feed trough 102 of the screw conveyor 1. The flow rate of alumina powder can be easily controlled by adjusting the speed of motor 201, thereby avoiding overload of trough 102 or blockage of alumina powder. Wire 501 is installed on the outer side of the feed plate 203 on the housing 101. The function of wire 501 is to discharge the static electricity generated between the feed plate 203 and the alumina powder. When the alumina powder rubs against the feed plate 203, static electricity is generated. If the static electricity is not discharged in time, it will cause the alumina powder to be adsorbed on the inner wall of the housing 101 or the feed plate 203, causing blockage or unstable flow, affecting production efficiency. Wire 501 is connected to the housing 101, and the static electricity is conducted to the grounding system through the grounding chain 505, thereby ensuring that the static electricity can be discharged safely and quickly.

[0043] Motor 1031 drives the spiral shaft 1032 to rotate, which in turn drives the spiral blades 1033 to rotate. The spiral blades 1033 then drive several blades 308 to rotate, thus feeding alumina powder. Each blade 308 has a rounded end face 309. The rounded end face 309 reduces the contact area between the blade and the alumina powder. Compared to a planar design, the contact between the rounded end face 309 and the alumina powder is more point-like or linear, thus reducing the coefficient of friction. The shape of the rounded end face 309 also helps the alumina powder slide more smoothly when it contacts the blade 308, rather than generating greater resistance as with a planar surface, reducing... The alumina powder is prevented from lingering and accumulating on the surface of the blade 308, further reducing friction. By reducing the friction between the blade 308 and the alumina powder, the speed and amount of charge transfer can be reduced. Reduced friction means fewer opportunities for electron transfer, thereby reducing the accumulation of static electricity. The arc surface 309 helps the alumina powder to be distributed more evenly during the conveying process and reduces accumulation on the end face of the blade 308. Due to the shape of the arc surface 309, the powder is more easily guided to the conveying direction of the spiral blade 1033 when it comes into contact with the blade 308, rather than lingering on the end face of the blade 308. This helps to maintain the continuity of the conveying process and avoid problems such as blockage and unstable flow.

[0044] Furthermore, the controller controls several motors 302 to operate, which drive rotating shaft 303 to rotate. Rotating shaft 303 drives main sprocket 304 to rotate, and main sprocket 304 drives one of its driven sprockets 305 to rotate via a chain. Several driven sprockets 305 are sequentially mounted with chains in pairs, driving the driven sprockets 305 to rotate. An arc-shaped chain cover 306 protects the chain. The driven sprockets 305 synchronously drive rotating column 307 to move forward. The rotating column 307 makes contact with the inner surface of the spiral blade 1033 during rotation. This causes the rotating columns 307 to stably drive the blade 308 to deflect at an angle. By adjusting the angle of the blade 308, a suitable angle helps the alumina powder flow smoothly within the screw conveyor 1, reducing the risk of accumulation and blockage. This ensures that the alumina powder is pushed evenly and continuously, avoiding local overload. Adjusting the angle of the blade 308 can change the relationship between the alumina powder and the blade 3033. The contact mode of 8 reduces wear on the blades 308 and the inner wall of the screw conveyor 1, further reducing static electricity generation. This allows the screw conveyor 1 to better adapt to alumina powders of different particle sizes and densities. The working angle of the blades 308 is adjusted according to the real-time flow rate, velocity, and accumulation of the alumina powder, thereby optimizing the distribution of alumina powder among the screw blades 1033 and avoiding local overload or idling. The angle deflection of the blades 308 can actively intervene in the flow trajectory of the alumina powder. When an alumina powder accumulation trend is detected in a certain area, the angle of the corresponding blades 308 is adjusted in real time. By changing the pushing direction or speed, the accumulation is dispersed, while maintaining the overall balance of the conveying flow, reducing the risk of blockage. The adjustment of the angle of the blades 308 can change the contact mode between the alumina powder and the trough 102. By avoiding continuous high-speed friction of alumina powder in local areas, and with the help of the carbon fiber conductive brush 504 and the grounding wire 503, static electricity is discharged, reducing the overall static electricity accumulation and further ensuring safe production.

[0045] During the angular deflection of several blades 308, the spiral blades 1033 drive the blades 308 to rotate, causing different surfaces of the blades 308 to contact the carbon fiber conductive brushes 504. This discharges static electricity from the surfaces of the blades 308. The static electricity generated by the spiral blades 1033 is also discharged through the second wire 502 of the bearing seat of the spiral shaft 1032. As the blades 308 rotate, their different surfaces sequentially contact the carbon fiber conductive brushes 504, ensuring that static electricity on the surfaces of the blades 308 is continuously and effectively discharged. This prevents the accumulation of static electricity on the surfaces of the blades 308, avoiding the formation of powder accumulation or agglomeration of alumina powder on the surfaces of the blades 308, which could lead to blockage of the trough 102 and unstable flow. This process not only addresses the static electricity on the surfaces of the blades 308 but also discharges the static electricity generated by the spiral blades 1033 through the second wire 502 of the bearing seat of the spiral shaft 1032, minimizing the accumulation of static electricity throughout the conveying system and thus reducing the safety risks caused by static electricity.

[0046] When the surface of the blade plate 308 is damaged, rotating the threaded pin 7 causes it to press against the clamping plate 403 within the threaded groove 6. This causes the clamping plate 403 to deflect the rotating column 402 at an angle, moving the clamping plate 403 into the column groove 401. At this time, the movable column 404 moves into the telescopic groove 406, simultaneously pressing the spring 405. This facilitates the separation of the rotating column 307 from the blade plate 308, making it easy to replace the blade plate 308. When installing the blade plate 308, simply insert it into the outside of the rotating column 307. The spring 405 elastically deforms, causing the clamping plate 403 to engage within the blade plate 308, thus allowing the blade plate 308 to be movably engaged with the outside of the rotating column 307. This facilitates the maintenance and replacement of the blade plate 308.
