Description

Technical Field

[0001] The present invention relates to the technical field of aluminum liquid refining, and specifically, to a multi-tube refining vehicle for aluminum liquid refining. Background Art

[0002] Aluminum and its alloys are widely used in our daily life and industrial production. Many components use aluminum or its alloys as raw materials, such as doors, windows, and automobile wheels. When melting aluminum and its alloys, it is generally necessary to refine the melt, that is, to remove impurities in the melt through various chemical or physical methods.

[0003] Regarding refining vehicles, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN222665951U discloses an aluminum liquid refining vehicle. The aluminum liquid refining vehicle includes a moving base, a linear slide table module, and a powder spraying component. The linear slide table module is horizontally rotatably arranged on the top of the base, and a limiting frame is fixedly connected to the movable end of the linear slide table module; the powder spraying component includes a support frame, an adjusting member, a powder spraying member, and a forward and reverse motor; the support frame is located above the moving base, and the bottom of the support frame has a limiting protrusion that matches the inner wall shape of the limiting frame; the adjusting members are arranged at the four corners of the support frame for lifting and adjusting the support frame; the forward and reverse motor is horizontally slidably arranged in the support frame, and one end of the output shaft of the forward and reverse motor is connected to one end of the powder spraying pipe of the powder spraying member, and the other end of the powder spraying pipe of the powder spraying member is bent downward and used as a powder spraying end. The present invention realizes multi-track and multi-angle movement through the horizontal linear movement and angular rotation of the steel pipe, meets the actual refining requirements, and eliminates the need for manual operation, ensuring the refining effect while reducing the operation safety hazard.

[0005] However, in the actual use process, there are still some problems:

[0006] 1. At present, during the use of traditional refining vehicles, the mixture formed by the reaction of the refining agent and the impurities in the aluminum liquid floats on the liquid surface. Due to the lack of an immediate cleaning mechanism, as the operation continues, the slag layer gradually thickens and expands in volume. When the operator needs to clean it, the high-temperature slag is extremely likely to splash out. Coupled with the limited operation space, it not only significantly increases the risk of scalding, but also may cause splashing due to the contact between the tool and the aluminum liquid, forming a safety hazard;

[0007] 2. Existing refining vehicles rely on the method of directly injecting the refining agent into the refining pipe. The refining agent is prone to accumulate in the pipe and is difficult to mix fully with the conveying gas, resulting in uneven dispersion when entering the aluminum liquid and unable to achieve full and efficient coverage of the aluminum liquid.

[0008] In view of this, we propose a multi-tube refining vehicle for aluminum liquid refining. Summary of the Invention

[0009] The purpose of the present invention is to provide a multi-tube refining vehicle for aluminum liquid refining, so as to solve the problems proposed in the above-mentioned background technology.

[0010] To achieve the above object, the present invention aims to provide a multi-tube refining vehicle for aluminum liquid refining, including a moving trolley. A control box and a gas tank are arranged on the surface of the moving trolley. A vertical frame is arranged at the center of the surface of the moving trolley. A rotating motor is arranged at the top of the vertical frame. A lead screw is arranged at the output end of the rotating motor. A moving seat is arranged on the surface of the lead screw. When the lead screw rotates, it drives the moving seat to move in the vertical direction. A spiral feeding pipe is arranged on the surface of the moving seat. A refining box is arranged at the top of the spiral feeding pipe. An extension plate is arranged at the end of the spiral feeding pipe. Strong magnets are arranged at both ends of the extension plate. An agitation assembly is arranged on the surface of the extension plate. A feeding pipe is arranged at the end of the spiral feeding pipe. An air inlet is arranged at the top of the feeding pipe. The air inlet is connected to the air outlet of the gas tank through an air pump. A connecting plate is arranged near the bottom of the feeding pipe. The agitation assembly includes a cylinder arranged on one side of the extension plate. A first rack is arranged on the piston rod at the end of the cylinder. The piston rod drives the first rack to move in the vertical direction. A double-headed gear rod is arranged on one side of the first rack. The double-headed gear rod is fixed above the connecting plate. When the first rack moves in the vertical direction, it drives the double-headed gear rod to engage and rotate. A driven gear is arranged at one end of the double-headed gear rod away from the first rack. A stirring rod is arranged at the bottom of the driven gear. A reciprocating assembly is arranged on one side of the double-headed gear rod. A slag collection assembly is arranged on the surface of the reciprocating assembly. The slag collection assembly automatically collects the floating slag in the aluminum liquid during the movement through the reciprocating assembly.

[0011] As a further improvement of this technical solution, the reciprocating assembly includes a second rack arranged on one side of the double-headed gear rod. A placing plate is arranged at the top of the second rack. When the double-headed gear rod moves in the vertical direction and drives the double-headed gear rod to rotate, the second rack arranged on one side of the double-headed gear rod moves vertically in the opposite direction to the first rack.

[0012] As a further improvement of this technical solution, column cylinders are arranged on both sides of the placing plate. Slide rods are slidably arranged on the inner walls of the column cylinders. Compression springs are arranged between the column cylinders and the slide rods. Clamping plates are arranged at the ends of the slide rods. A slag collection assembly is arranged between the clamping plates.

[0013] As a further improvement of this technical solution, a branch connecting pipe is arranged at the bottom of the feeding pipe to expand the dispersion range of the refining agent through the branch connecting pipe.

[0014] As a further improvement of this technical solution, the slag collection assembly includes a barrel body. A collection seat is clamped at the bottom of the barrel body. Liquid leakage holes are formed on the surface of the barrel body, and the liquid leakage holes are arranged in an array on the surface of the barrel body.

[0015] As a further improvement of the technical solution, a stepped block is provided at the center of the barrel body. The cross-section of the stepped block is trapezoidal, the diameter of the bottom of the stepped block is larger than that of the top, and there is a gap between the stepped block and the barrel body. The floating slag enters the collection seat through the gap for automatic collection.

[0016] As a further improvement of the technical solution, a hollow column is provided at the top of the barrel body. A connecting rod is slidably arranged inside the hollow column. An elastic member is provided between the hollow column and the connecting rod. A baffle is provided at the bottom of the hollow column. The baffle fills the gap, and the surface of the baffle is in a slope shape.

[0017] As a further improvement of the technical solution, a pull rod is provided at the top of the connecting rod. The pull rod passes through the hollow column to the upper part of the barrel body. A metal block is provided at the center of the pull rod. When the metal block moves to the position of the strong magnet, it is magnetically attracted and moves in the vertical direction.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the multi-tube refining vehicle for aluminum liquid refining, the piston rod at the end of the air cylinder pushes the first rack to reciprocate in the vertical direction. During the movement of the air cylinder, the double-headed gear rod is driven to rotate. When the double-headed gear rod rotates, the driven gear is driven to mesh and rotate. When the driven gear rotates, the stirring rod is driven to rotate coaxially. When the stirring rod rotates, it stirs the aluminum liquid, accelerating the mixing of the refining agent and the aluminum liquid, so as to facilitate the rapid reaction with impurities for impurity removal.

[0020] 2. In the multi-tube refining vehicle for aluminum liquid refining, when the piston rod at the end of the air cylinder drives the first rack to move downward in the vertical direction to drive the stirring rod to rotate and stir the aluminum liquid, the second rack drives the placement plate to move upward in the vertical direction. The barrel body placed on the surface of the placement plate moves from the aluminum solution to the outside. At this time, the aluminum liquid leaks out from the liquid leakage holes opened on the surface of the barrel body, and the floating impurity mixture formed by the impurities and the refining agent in the aluminum liquid falls on the bottom of the collection seat, so as to facilitate the automatic collection of impurities, reduce the furnace operation of the operators, and improve the safety of refining.

[0021] 3. In the multi-tube refining car for aluminum liquid refining, when the pull rod approaches a strong magnet during the movement of the barrel body, the metal block provided at the center of the pull rod is attracted by the magnetic force, so that the pull rod moves in the vertical direction. The pull rod pulls the connecting rod during the movement, and the connecting rod drives the baffle to move up in the vertical direction, so that the gap formed between the barrel body and the step block is opened, and the impurity mixture accumulated on the surface of the baffle falls into the collecting seat. When the barrel body moves downward in the vertical direction, the gravitational force on the pull rod disappears, and the connecting rod is driven by the force of the elastic part to drive the baffle to reset, so that the baffle blocks the gap between the barrel body and the step block, thereby avoiding the impurity mixture from overflowing from the collecting seat, facilitating the rapid collection of the impurity mixture, and avoiding the impurity mixture from hindering heat transfer, resulting in uneven temperature of the aluminum liquid, and affecting the efficiency of the subsequent refining process.

An agitation assembly 300 is provided on the surface of the extension plate 208. A feeding pipe 206 is provided at the end of the spiral feeding pipe 204. An air inlet 207 is provided at the top of the feeding pipe 206. The air inlet 207 is connected to the outlet of the gas tank 102 through an air pump. A connecting plate 209 is provided near the bottom of the feeding pipe 206. The agitation assembly 300 includes a cylinder 301 provided on one side of the extension plate 208. A first rack 302 is provided on the piston rod at the end of the cylinder 301. The piston rod drives the first rack 302 to move in the vertical direction. A double-headed gear rod 303 is provided on one side of the first rack 302. The double-headed gear rod 303 is fixed above the connecting plate 209. When the first rack 302 moves in the vertical direction, it drives the double-headed gear rod 303 to engage and rotate. A driven gear 304 is provided at the end of the double-headed gear rod 303 away from the first rack 302. A stirring rod 305 is provided at the bottom of the driven gear 304. A reciprocating assembly 400 is provided on one side of the double-headed gear rod 303. A slag collection assembly 500 is provided on the surface of the reciprocating assembly 400. During the movement of the slag collection assembly 500 through the reciprocating assembly 400, the floating slag in the molten aluminum is automatically collected.

[0039] The refining of molten aluminum is a crucial process. Its purpose is to remove impurities in the molten aluminum to improve the quality of the molten aluminum. Currently, a refining agent is usually added to the molten aluminum. In order to quickly and evenly disperse the refining agent to every corner of the molten aluminum and improve the reaction efficiency with impurities, therefore, the stirring assembly 300 includes a cylinder 301 provided on one side of the extension plate 208. A first rack 302 is provided on the piston rod at the end of the cylinder 301. The piston rod drives the first rack 302 to move in the vertical direction. A double-headed gear rod 303 is provided on one side of the first rack 302. The double-headed gear rod 303 is fixed above the connecting plate 209. When the first rack 302 moves in the vertical direction, it drives the double-headed gear rod 303 to engage and rotate. A driven gear 304 is provided at one end of the double-headed gear rod 303 away from the first rack 302. A stirring rod 305 is provided at the bottom of the driven gear 304. Control the moving trolley 100 to move beside the molten aluminum furnace. Control the output shaft of the rotating motor 201 to drive the lead screw 202 to rotate. When the lead screw 202 rotates, the moving seat 203 moves in the vertical direction, so that the spiral feeding pipe 204 drives the feeding pipe 206 into the interior of the melting furnace. Control the air pump to make the gas in the gas tank 102 enter the interior of the feeding pipe 206 through the air inlet 207, so as to quickly disperse the refining agent into the molten aluminum. At this time, the piston rod at the end of the cylinder 301 is pushed to move the first rack 302 reciprocally in the vertical direction. During the movement of the cylinder 301, it drives the double-headed gear rod 303 to rotate. When the double-headed gear rod 303 rotates, it drives the driven gear 304 to engage and rotate. When the driven gear 304 rotates, it drives the stirring rod 305 to rotate coaxially. When the stirring rod 305 rotates, it stirs the molten aluminum, accelerating the mixing of the refining agent and the molten aluminum, so as to facilitate the reaction with impurities for impurity removal quickly.

[0040] Considering that when removing impurities in molten aluminum, the impurities react with the refining agent to form a mixture that floats on the surface of the molten aluminum. To facilitate the collection of the floating impurities, the reciprocating assembly 400 includes a second rack 401 provided on one side of the double-headed gear rod 303. A placement plate 402 is provided at the top of the second rack 401. When the double-headed gear rod 303 moves vertically and drives the double-headed gear rod 303 to rotate, the second rack 401 provided on one side of the double-headed gear rod 303 moves vertically in the opposite direction to the first rack 302. Column cylinders 403 are provided on both sides of the placement plate 402. A sliding rod 404 is slidably provided on the inner wall of the column cylinder 403. A compression spring 405 is provided between the column cylinder 403 and the sliding rod 404. A clamping plate 406 is provided at the end of the sliding rod 404. A slag collection assembly 500 is provided between the clamping plates 406. When the first rack 302 moves to drive the stirring rod 305 to rotate and stir the molten aluminum, during the mixing process of the impurities in the molten aluminum and the refining agent, the second rack 401 provided on one side of the double-headed gear rod 303 drives the placement plate 402 to move relative to the first rack 302. Since the slag collection assembly 500 is provided on the surface of the placement plate 402, during the reciprocating movement of the slag collection assembly 500, the impurity mixture floating on the surface of the molten aluminum is automatically collected, avoiding the increase in volume and weight caused by the accumulation of the impurity mixture, and reducing the labor intensity of the operator for collecting the impurity mixture.

[0041] To facilitate the acceleration of the mixing of molten aluminum and the refining agent and improve the refining efficiency of the molten aluminum, a split joint pipe is provided at the bottom of the feeding pipe 206. By means of the split joint pipe, the dispersion range of the refining agent is increased. The gas flow control valve is adjusted so that the gas in the gas tank 102 enters the interior of the feeding pipe 206 through the air inlet 207. After the gas is mixed with the refining agent, driven by the gas, the refining agent is sprayed into the molten aluminum at a high speed from the lower ends of the split joint pipes provided on both sides of the bottom of the feeding pipe 206. The operator can also control the movement of the mobile trolley 100 through the controller, so that the refining vehicle slowly moves beside the molten aluminum melting furnace, ensuring that all parts of the molten aluminum can be fully mixed with the refining agent, and further ensuring that the molten aluminum can be fully refined.

[0042] Considering that impurities in the molten aluminum react with the refining agent to form floating substances, in order to facilitate the collection of the formed floating impurities, the slag collection assembly 500 includes a barrel body 501. A collection seat 502 is clamped at the bottom of the barrel body 501. Liquid leakage holes are formed on the surface of the barrel body 501, and the liquid leakage holes are arranged in an array on the surface of the barrel body 501. When the piston rod at the end of the air cylinder 301 drives the first rack 302 to move downward in the vertical direction to drive the stirring rod 305 to rotate and stir the molten aluminum, the second rack 401 drives the placement plate 402 to move upward in the vertical direction. The barrel body 501 placed on the surface of the placement plate 402 moves from the aluminum solution to the outside. At this time, the molten aluminum leaks out from the liquid leakage holes formed on the surface of the barrel body 501, and the floating impurity mixture formed by the impurities and the refining agent in the molten aluminum falls on the bottom of the collection seat 502, thus facilitating the automatic collection of impurities, reducing the work of operators in the furnace, and improving the safety of refining.

[0043] Considering that during the input process of the refining agent, impurity mixtures are continuously generated. During the repeated movement of the barrel body 501 in and out of the molten aluminum, the impurity mixture falling into the collection seat 502 re-enters the molten aluminum, and the molten aluminum mixture collected inside it is likely to float out, resulting in low collection efficiency of the impurity mixture. Therefore, a stepped block 503 is provided at the center of the barrel body 501. The cross-section of the stepped block 503 is trapezoidal, the bottom diameter of the stepped block 503 is larger than the top diameter, and there is a gap between the stepped block 503 and the barrel body 501. The floating slag enters the collection seat 502 through the gap for automatic collection. When the barrel body 501 moves vertically to collect the impurity mixture floating on the surface of the molten aluminum, when the barrel body 501 moves from the inside of the furnace molten aluminum to the outside, the excess molten aluminum leaks out from the liquid leakage holes provided on the surface of the barrel body 501, and the collected impurity mixture falls on the bottom of the collection seat 502 under the action of gravity. When the barrel body 501 moves vertically downward into the molten aluminum, the stepped block 503 blocks the impurity mixture collected at the bottom of the collection seat 502, reducing the floating out of the collected impurity mixture from the barrel body 501, thereby improving the collection efficiency of impurities.

[0044] In order to improve the collection of the impurity mixture generated during the refining process, a hollow column 504 is provided at the top of the barrel body 501. A connecting rod 505 is slidably arranged inside the hollow column 504. An elastic member 506 is arranged between the hollow column 504 and the connecting rod 505. A baffle 507 is provided at the bottom of the hollow column 504. The baffle 507 fills the gap. The surface of the baffle 507 is in a slope shape. A pull rod 508 is provided at the top of the connecting rod 505. The pull rod 508 penetrates through the hollow column 504 to the upper part of the barrel body 501. A metal block is provided at the center of the pull rod 508. When the metal block moves to the strong magnet 210, it is magnetically attracted and moves in the vertical direction. When the placement plate 402 drives the barrel body 501 to reciprocate in the vertical direction in the melting furnace, the impurity mixture formed by the refining agent and the impurities in the molten aluminum floats on the surface of the molten aluminum. When the barrel body 501 moves away from the molten aluminum, the impurity mixture floating on the surface of the molten aluminum is collected into the barrel body 501. When the barrel body 501 moves away from the molten aluminum, the molten aluminum is discharged from the liquid leakage holes opened on the surface of the barrel body 501. At the same time, when the barrel body 501 moves, the pull rod 508 approaches the strong magnets 210 arranged on both sides of the extension plate 208. Under the action of the magnetic force, the metal block provided at the center of the pull rod 508 is attracted, so that the pull rod 508 moves in the vertical direction. During the movement of the pull rod 508, the connecting rod 505 is pulled. The connecting rod 505 drives the baffle 507 to move upward in the vertical direction. The baffle 507 is hollow. During the movement of the baffle 507, the gap formed between the barrel body 501 and the step block 503 is opened. The impurity mixture accumulated on the surface of the baffle 507 falls into the collection seat 502. When the barrel body 501 moves downward in the vertical direction, the gravitational force on the pull rod 508 disappears. The connecting rod 505 drives the baffle 507 to reset under the action of the elastic member 506, so that the baffle 507 blocks the gap generated between the barrel body 501 and the step block 503, thereby preventing the impurity mixture from overflowing from the inside of the collection seat 502, facilitating the rapid collection of the impurity mixture, and thus improving the impurity removal efficiency.

[0045] Specifically, when in use, control the moving trolley 100 to move to the side of the molten aluminum furnace. Control the output shaft of the rotating motor 201 to drive the lead screw 202 to rotate. When the lead screw 202 rotates, the moving seat 203 moves in the vertical direction, so that the spiral feeding pipe 204 drives the feeding pipe 206 to enter the melting furnace. Control the air pump to make the gas in the gas tank 102 enter the feeding pipe 206 through the air inlet 207, so as to quickly disperse the refining agent into the molten aluminum. At this time, the piston rod at the end of the air cylinder 301 pushes the first rack 302 to reciprocate in the vertical direction. During the movement of the air cylinder 301, the double-headed gear rod 303 is driven to rotate. When the double-headed gear rod 303 rotates, the driven gear 304 is driven to mesh and rotate. When the driven gear 304 rotates, the stirring rod 305 is driven to rotate coaxially. When the stirring rod 305 rotates, the molten aluminum is stirred to accelerate the mixing of the refining agent and the molten aluminum, so as to facilitate the rapid reaction with the impurities for impurity removal;

[0046] The first rack 302 moves to drive the stirring rod 305 to rotate and agitate the molten aluminum. When the impurities in the molten aluminum are mixed with the refining agent, the second rack 401 on one side of the double-headed gear rod 303 drives the placing plate 402 to move relative to the first rack 302. Since the slag collection assembly 500 is provided on the surface of the placing plate 402, during the reciprocating movement of the slag collection assembly 500, the impurity mixture floating on the surface of the molten aluminum is automatically collected, avoiding the increase in volume and weight caused by the accumulation of the impurity mixture, and reducing the labor intensity of the operator for collecting the impurity mixture.

[0047] When the piston rod at the end of the cylinder 301 drives the first rack 302 to move downward in the vertical direction to drive the stirring rod 305 to rotate and agitate the molten aluminum, the second rack 401 drives the placing plate 402 to move upward in the vertical direction. The barrel 501 placed on the surface of the placing plate 402 moves out of the molten aluminum solution to the outside. At this time, the molten aluminum leaks out from the liquid leakage holes opened on the surface of the barrel 501, and the floating impurity mixture formed by the impurities and the refining agent in the molten aluminum falls to the bottom of the collection seat 502, thus facilitating the automatic collection of impurities, reducing the furnace operation of the operator, and improving the safety of refining.

[0048] When the placing plate 402 drives the barrel 501 to reciprocate in the vertical direction in the furnace, the impurity mixture formed by the refining agent and the impurities in the molten aluminum floats on the surface of the molten aluminum. When the barrel 501 moves away from the molten aluminum, the floating impurity mixture on the surface of the molten aluminum is collected into the barrel 501. When the barrel 501 moves away from the molten aluminum, the molten aluminum is discharged from the liquid leakage holes opened on the surface of the barrel 501. At the same time, when the pull rod 508 approaches the strong magnet 210 during the movement of the barrel 501, under the action of the magnetic force, the metal block provided at the center of the pull rod 508 is attracted, so that the pull rod 508 moves in the vertical direction. During the movement of the pull rod 508, the connecting rod 505 is pulled, and the connecting rod 505 drives the baffle 507 to move upward in the vertical direction. The baffle 507 is hollow. During the movement of the baffle 507, the gap formed between the barrel 501 and the step block 503 is opened, and the impurity mixture accumulated on the surface of the baffle 507 falls into the collection seat 502. When the barrel 501 moves downward in the vertical direction, the gravitational force on the pull rod 508 disappears, and the connecting rod 505 drives the baffle 507 to reset under the action of the elastic member 506, so that the baffle 507 blocks the gap generated between the barrel 501 and the step block 503, thus preventing the impurity mixture from overflowing from the inside of the collection seat 502, facilitating the rapid collection of the impurity mixture, and thus improving the impurity removal efficiency.
